Atherogenic dyslipidemia and oxidative stress: a new look

2009

Although results from in vitro studies and clinical trials demonstrate strong associations between oxidative stress and cardiovascular risk, to date still no convincing data are available to suggest that treatment with antioxidants might reduce vascular events. Oxidative modifications of low-density lipoproteins (LDL) represent an early stage of atherosclerosis, and small, dense LDL are more susceptible to oxidation than larger, more buoyant particles. Oxidized LDL are independent predictors of subclinical and clinical atherosclerosis. Recent studies suggested that novel therapeutic strategies may take into account the removal of such particles from circulation. Future research is required …

Effects of Rosiglitazone on Fasting and Postprandial Low- and High-Density Lipoproteins Size and Subclasses in Type 2 Diabetes

2010

Rosiglitazone may increase cardiovascular risk in patients with type 2 diabetes. Yet, its effects on atherogenic dyslipidemia are still not fully elucidated. In a prospective open-label study rosiglitazone (4 mg/day for 12 weeks) was added to a maximum of 2 oral antidiabetic drugs in 18 diabetic patients. We evaluated the effects on plasma lipids before and after an oral fat load. The size and subclasses of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) were also determined (by gradient gel electrophoresis). Rosiglitazone improved glycosylated hemoglobin ([HbA1c] P = .0023), without significant effects on fasting and postprandial plasma lipids. Fasting LDL size increased …

Subjects with HLA-B44 and HLA-Cw5 antigens were more represented in patients with AICU than in control group. Subjects with HLA-A11, HLA-B13, HLACw4, and HLA-Cw7 antigen were more represented in control group than in patients with AICU. Multiple logistic regression demonstrated an association of HLA-Cw4 and HLA-Cw7 with a lower risk of AICU, whereas carriers of HLA-B44 phenotype had a higher…

“The Linosa Study”: Epidemiological and heritability data of the metabolic syndrome in a Caucasian genetic isolate

2009

Abstract Background and aims Growing evidence suggests that the metabolic syndrome (MetS) has both a genetic and environmental basis. To evaluate the possibility of a further genetic analysis, we estimated prevalence rates and heritabilities for the MetS and its individual traits in the adult population of Linosa, a small and isolated Italian Island in the southern-central part of the Mediterranean Sea. Methods and results The Linosa Study (LiS) group consisted of 293 Caucasian native subjects from 51 families (123 parents; 170 offsprings). The MetS was defined according to NCEP/ATP III criteria and the following prevalence rates were calculated: hyperglycaemia 20.3%; central obesity 34.9%;…

Atherogenic forms of dyslipidaemia in women with polycystic ovary syndrome.

2009

OBJECTIVE: Dyslipidaemia is very common in patients with polycystic ovary syndrome (PCOS) but, beyond plasma lipids, atherogenic lipoprotein (Lp) and apolipoprotein (apo) alterations are still ill defined. DESIGN: We measured concentrations of apoB, Lp(a) and small, dense low-density lipoprotein (LDL) in 42 patients with PCOS [age: 28 +/- 7 years, body mass index (BMI): 27 +/- 5 kg/m(2)] vs. 37 age- and BMI-matched healthy controls. METHODS: Elevated Lp(a) levels considered were those > 30 mg/dl while elevated apoB concentrations were those > 100 g/l. RESULTS: Polycystic ovary syndrome showed increased triglycerides levels (p = 0.0011) and lower high-density lipoprotein (HDL)-cholesterol co…

A case of bowel schistosomiasis not adhering to endoscopic findings

2005

Schistosomiasis is a chronic worm infection caused by a species of trematodes, the Schistosomes. We may distinguish a urinary form from Schistosomes haematobium and an intestinal-hepatosplenic form mainly from Schistosomes mansoni characterized by nausea, meteorism, abdominal pain, bloody diarrhea, rectal tenesmus, and hepatosplenomegaly. These infections represent a major health issue in Africa, Asia, and South America, but recently S mansoni has increased its prevalence in other continents, such as Europe countries and North America, due to international travelers and immigrants, with several diagnostic and prevention problems. We report a case of a 24-year-old patient without HIV infecti…

Clinical importance of eosinophil count in nasal fluid in patients with allergic and non-allergic rhinitis

2009

Eosinophil count in nasal fluid (ECNF) was used to differentiate nasal pathologies. Receiver Operating Characteristic (ROC) curve analysis and the area under the curve (AUC) were performed to evaluate the ECNF's accuracy in distinguishing allergic rhinitis (AR) from non-allergic rhinitis (NAR). We also evaluated the accuracy of ECNF in recognizing patients with mild and severe symptoms of rhinitis and patients with ineffective and effective clinical responses to antihistamines. 1,170 consecutive adult patients with a clinical history of rhinitis were studied. ECNF's median in AR was 6.0 and 2.0 in NAR and the best cut-off value was > 3.0, AUC = 0.75. ECNF's median in AR with mild nasal …

Determinants of bronchial hyperresponsiveness in subjects with rhinitis.

2005

Subjects with rhinitis but without asthma may have coexisting bronchial hyperresponsiveness, although the reasons for this are uncertain. To evaluate the factors that determine BHR in rhinitis we examined 410 patients with symptomatic rhinitis with forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) ≥ 80% of the predicted value. In all subjects a skin prick test (SPT) was performed, a determination of total serum IgE and an eosinophils count in the blood. Of the 410 subjects we found that 161 (39.3%) exhibited a methacholine PD20 of 800 mg or less (Group A), whereas 249 (60.7%) had a methacholine PD20 more of 800 mg (Group B). Despite the matched mean values for FEV…

Effects of hypocaloric diets with different glycemic indexes on endothelial function and glycemic variability in overweight and in obese adult patien…

2013

Background & aims: The role of glycemic index of the diet in glucose control and cardiovascular prevention is still not clear. The aim of this study was to determine the effects of hypocaloric diets with different glycemic indexes and glycemic loads on endothelial function and glycemic variability in nondiabetic participants at increased cardiovascular risk. Methods: Forty nondiabetic obese participants were randomly assigned to a three-month treatment with either a low glycemic index (LGI; n ¼ 19) or high glycemic index (HGI; n ¼ 21) hypocaloric diet with similar macronutrient and fiber content. Endothelial function was measured as flow-mediated dilatation (FMD) of the brachial artery befo…

Significance of persistence of antibodies against Leishmania infantum in Sicilian patients affected by acute visceral leishmaniasis.

2012

The background of this article is as follows: Few data are available about the persistence of serum-specific IgG antibodies to L. infantum after acute VL. The objective of this article is to evaluate the persistence of antibodies against L. infantum in patients healed from acute VL, and the kinetic of the same antibodies observed in 2 cases of VL relapse and 2 cases of resistance to therapy. The methods which we used to obtain our objective are the following: 55 apparently immunocompetent, HIV-negative patients were examined for antibodies to L. infantum by IFAT over 14 years period, and we got the following results: Serum-specific IgG antibodies titers decrease slowly, but constantly. In t…

Is diabetes the cost to pay for a greater cardiovascular prevention?

2010

The recent JUPITER (Justification for the Use of statins in Primary prevention: an Intervention Trial Evaluating Rosuvastatin) trial is another study providing evidence about the effectiveness of statin therapy in reducing cardiovascular risk. Yet, in this study significantly higher glycated hemoglobin levels and incidence rates of diabetes were observed in persons treated with rosuvastatin than the placebo group. It should be noted that adverse effects on glucose metabolism have already been reported, albeit rarely, in previous trials with statins. Although the exact mechanisms involved are unknown, it seems that statins may deteriorate glycemic control by decreasing different metabolites,…

The therapeutic modulation of atherogenic dyslipidemia and inflammatory markers in the metabolic syndrome: what is the clinical relevance?

2008

The metabolic syndrome consists of a constellation of clinical and biochemical risk factors that cluster together and heighten the risk for atherogenesis, cardiovascular diseases, and diabetes. Established risk cardiovascular factors like hypertension, atherogenic dyslipidaemia, and glucose intolerance occur in the setting of insulin resistance and central adiposity, with genetic and environmental influences modulating the ultimate risk. Chronic insults to the endothelium take its toll in the form of silent as well as clinically evident cardiovascular events. The cellular and vascular accompaniments have shed some light into the underlying pathophysiology. Heightened, low-grade inflammatory…

The Val432Leu polymorphism of the CYP1B1 gene is associated with differences in estrogen metabolism and bone density.

2009

Polymorphisms of the CYP450 genes that encode for the enzymes that metabolize estrogen are linked to hormone-related cancers. We investigated the impact of two polymorphisms of the CYP1B1 gene previously reported to be associated with hormone-related disorders on estrogen metabolism and bone mineral density (BMD), another hormone-dependent condition, in women from different ethnic backgrounds. Four hundred sixty-eight postmenopausal Caucasian women, 220 from St. Louis, MO, USA (mean age=63.5+/-0.53 years) and 248 from Palermo, Italy (mean age=72.9+/-0.44 years) participated in the study. Measurements of urinary estrogen metabolites by enzyme-linked immunoassay, serum estradiol by ultrasensi…

LDL size and subclasses in patients with abdominal aortic aneurysm

2009

Abstract Since the type of dyslipidemia in patients with abdominal aortic aneurysm (AAA) is still insufficiently defined, we measured plasma lipids and analyzed LDL size and subclasses by gradient gel electrophoresis in 30 male patients (69±6 years, BMI: 27±3) with newly diagnosed AAA and in 26 age- and BMI-matched male healthy controls. Patients with AAA had lower HDL-cholesterol ( p p =.0002) and smaller LDL size ( p p =.0210) in relation to controls. Multivariate analysis also showed that small LDL size was independently associated with the presence of AAA ( p =.0350). Increased levels of small, dense LDL may therefore represent a common feature in patients with AAA.

Quantitative and qualitative effects of rosuvastatin on LDL-cholesterol: what is the clinical significance ?

2009

Summary Background:  Statins have emerged as the global leader in pharmacologic therapy for dyslipidaemia, and rosuvastatin has demonstrated clinical efficacy as well as safety in several clinical trials and postmarketing analyses. Aim:  The present article reviewed the effects of rosuvastatin on the quantity and the quality of low-density lipoproteins (LDL). Methods:  We searched for and reviewed all the available evidence in a systematic way. A literature search (by Medline and Scopus) was performed using the following headings: ‘LDL-cholesterol’, ‘LDL size’, ‘LDL subclasses’, ‘small dense LDL’, ‘apolipoprotein B, apo B’ and ‘rosuvastatin’ up to 11 November 2008. The authors also manually…

Ezetimibe, cardiovascular risk and atherogenic dyslipidaemia.

2010

Ezetimibe is a selective cholesterol absorption inhibitor with an excellent side-effect profile, able to reduce low-density lipoprotein (LDL) cholesterol by 15-25% from baseline in monotherapy and on top of statins and fibrates. Yet, it seems that ezetimibe produces quantitative rather than qualitative changes in LDL, with small net effects on atherogenic dyslipidaemia. This is supported by findings from the Ezetimibe and Simvastatin in Hypercholesterolemia Enhances Atherosclerosis Regression (ENHANCE) study on atherosclerosis progression, where the addition of ezetimibe to simvastatin in patients with heterozygous familial hypercholesterolaemia did not affect the mean change in carotid int…

Small, dense low-density lipoproteins (LDL) are predictors of cardio- and cerebro-vascular events in subjects with the metabolic syndrome

2009

Summary Objective  Small, dense low-density lipoproteins (LDL) are a feature of the metabolic syndrome (MS) but their predictive role still remains to be established. We performed a 2-year follow-up study in 124 subjects with MS (63 ± 6 years), as defined by the American Heart Association/National Heart, Lung and Blood Institute guidelines, to assess clinical and biochemical predictors of cerebro- and cardio-vascular events. Methods and results  Beyond traditional cardiovascular risk factors, we measured LDL size and subclasses by gradient gel electrophoresis. Clinical events were registered in the 25% of subjects. At univariate analysis subjects with events had increased prevalence of elev…

Low serum levels of 25-hydroxy vitamin D in adults affected by thalassemia major or intermedia

2006

Adult thalassemic patients have reduced bone mass due to disturbances in several different mechanisms affecting bone turnover. To determine if vitamin D deficiency contributes to the low bone mass of adult thalassemic subjects, we studied serum 25-OH-vitamin D levels in 90 patients (age ranging between 21 and 48 years) affected with thalassemia major (TM) and 35 (age 21-56 years) with thalassemia intermedia (TI). TM patients had been receiving regular transfusions from the age of 2 years and had increased serum ferritin, glutamic oxalacetic transaminase, glutamic piruvic transaminase as well as low bone density (L1-L4 Z score -2.07 +/- 0.2). TI patients did not receive transfusions, but the…

Milder forms of atherogenic dyslipidemia in ovulatory versus anovulatory polycystic ovary syndrome phenotype

2017

BACKGROUND: Dyslipidemia is common in women with polycystic ovary syndrome (PCOS) but its prevalence in different PCOS phenotypes is still largely unknown. METHODS: We measured plasma lipids and lipoproteins in 35 anovulatory PCOS (age: 25 ± 6 years, BMI: 28 ± 6 kg/m2), 15 ovulatory PCOS (age: 30 ± 6 years, BMI: 25 ± 3 kg/m2) and 27 healthy women (controls) age- and BMI-matched with ovulatory PCOS. PCOS was diagnosed by the presence of clinical or biologic hyperandrogenism associated with chronic anovulation and/or polycystic ovaries at ultrasound. In women with normal menses chronic anovulation was indicated by low serum progesterone levels (<9.54 nmol/l) during midluteal phase (days 21…

Prevalence and predictors of left ventricular hypertrophy in patients with hypertension and normal electrocardiogram.

2013

Background: Electrocardiography (ECG) has low sensitivity for detecting left ventricular hypertrophy (LVH), while echocardiography cannot be routinely performed. Design/methods: In this study we evaluate the prevalence of LVH and diastolic dysfunction in hypertensive patients with normal ECG. We excluded patients with cardiovascular (CV) diseases, diabetes, chronic kidney disease, or presenting ECG-LVH or other ECG anomalies. The enrolled 440 hypertensive patients underwent echocardiographic examination (Acuson Sequoia 512); LV mass was indexed by body surface area (LVMI) and LVH was defined as LVMI >125 g/m2 in men and >110 g/m2 in women. Diastolic function was evaluated by mitral inflow a…

SummaryBackgroundDiagnosing asthma cannot be always easy. It is important to consider the validity of the diagnostic tests, and/or how much more commonly they are positive in patients with asthma compared to healthy subjects and, particularly, to patients with asthma-like symptoms.ObjectiveTo evaluate the validity of diagnostic tests for asthma, in terms of sensitivity, specificity, positive and negative predictive values, in patients with bronchial asthma compared to patients affected by gastro-oesophageal reflux disease (GERD) with asthma-like symptoms, and healthy control subjects without asthma and gastro-oesophageal reflux (GER).DesignSingle-center, cross-sectional, observational study…

“European Panel on Low Density Lipoprotein (LDL) Subclasses”: A Statement on the Pathophysiology, Atherogenicity and Clinical S…

2011

Aim of the present Consensus Statement is to provide a comprehensive and up to-date document on the pathophysiology, atherogenicity and clinical significance of low density lipoproteins (LDL) subclasses. We sub-divided our Statement in 2 sections: section I discusses the pathophysiology, atherogenicity and measurement issues, while section II is focused on the effects of drugs and lifestlyle modifications. Suggestions for future research in the field are highlighted at the end of section II. Each section includes Conclusions.

The endocrine response to severe burn trauma.

2013

The endocrine system is frequently altered after a major burn trauma. Besides the endocrine response to stress characterized by hypercortisolism, several hypothalamus-hypophysis-target gland axes are rapidly perturbed within a few days. These alterations can persist in the long term and deserve an appropriate treatment. Disturbances in water clearance and glucidic metabolism are also common and need to be diagnosed and corrected to decrease morbidity in such patients. Bone and mineral metabolism is deeply compromised and requires correction of mineral abnormalities in order to improve symptoms and prevent bone loss. No large prospective and/or intervention trials are available to date to el…

Cilostazol and atherogenic dyslipidemia: a clinically relevant effect

2011

Cilostazol is a reversible, selective inhibitor of PDE3A able to significantly improve walking distance in patients with intermittent claudication. However, beyond its antiplatelet and vasodilator properties, cilostazol seems to have significant effects on atherogenic dyslipidemia.The effects of cilostazol on plasma lipids, lipoproteins, apolipoproteins and postprandial lipemia are reviewed. A literature search (using Medline and Scopus) was performed up to 24 October 2010. The authors also manually reviewed the references of selected articles for any pertinent material.Cilostazol is able to significantly lower plasma triglyceride levels, with a concomitant increase in high-density lipoprot…

The Clinical Relevance of LDL Size and Subclasses Modulation in Patients with Type-2 Diabetes

2007

increasing evidence suggest that the "quality" rather than only the "quantity" of low density lipoproteins (LDL) exerts a great influence on the cardiovascular risk. Hypertriglyceridemia, low HDL-cholesterol and increased levels of small dense LDL characterise diabetic dyslipidemia. in subjects with type-2 diabetes LDL size seems also to represent a good marker of clinical apparent and non-apparent atherosclerosis. Recently, the Coordinating Committee of the National Cholesterol Education Program stated that high-risk patients may benefit of stronger therapeutical approaches, a category of subjects that include those with type-2 diabetes. Screening for the presence of small, dense LDL may p…

Abdominal fat quantity and distribution in women with polycystic ovary syndrome and extent of its relation to insulin resistance.

2007

Composizione corporea in relazione alla sindrome dell'ovaio policistico. Increased abdominal fat has been linked to insulin resistance and increased cardiovascular risk. Because many patients with polycystic ovary syndrome (PCOS) present abdominal obesity, it may be the cause of insulin resistance in this disorder.Setting: Fat quantity and distribution were evaluated by dual x-ray absorptiometry at the Departments of Clinical Medicine at the University of Palermo and the University of Naples, Italy.Patients: A total of 110 patients with PCOS and 112 weight-matched controls were studied. Anthropometric data, blood glucose, serum insulin, and testosterone were evaluated. Total, trunk, and cen…

Assessing cardiovascular risk in Mediterranean women with polycystic ovary syndrome

2010

Background: Although dyslipidemia is common in the polycystic ovary syndrome (PCOS), current diagnostic guidelines suggest to evaluate only plasma HDL-cholesterol and triglyceride concentrations, assuming that, in this disorder, cardiovascular risk is mainly due to the presence of the metabolic syndrome (MS). In the US, MS has been found in up to 50% of PCOS, but in other countries its prevalence is lower. Methods: We compared the prevalence of MS with that of increased LDL- and non-HDL-cholesterol levels in 350 Mediterranean PCOS women (244 anovulatory and 106 ovulatory), and 95 normo-weight and 90 body mass index (BMI)-matched controls. Results: The prevalence of MS was 7.1% in PCOS, high…

Effects of statins, fibrates, rosuvastatin, and ezetimibe beyond cholesterol: the modulation of LDL size and subclasses in high-risk patients.

2007

Increasing evidence suggests that the quality-rather than just the quantity-of low-density lipoproteins (LDLs) exerts a great influence on cardiovascular risk. LDLs comprise multiple subclasses with discrete size and density, and different physicochemical composition, metabolic behaviors, and atherogenicity. Individuals generally cluster into 2 broad subgroups. Most have a predominance of large LDLs, and some have a higher proportion of small particles. Small, dense LDLs are good predictors of cardiovascular events and progression of coronary artery disease. Their predominance has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Tre…

Diagnostic Accuracy of Fecal Calprotectin Assay in Distinguishing Organic Causes of Chronic Diarrhea from Irritable Bowel Syndrome: A Prospective Stu…

2003

AbstractBackground: Fecal calprotectin (FC) has been proposed as a marker of inflammatory bowel disease (IBD), but few studies have evaluated its usefulness in patients with chronic diarrhea of various causes. We evaluated the diagnostic accuracy of a FC assay in identifying “organic” causes of chronic diarrhea in consecutive adults and children.Methods: We consecutively enrolled 70 adult patients (30 males, 40 females; median age, 35 years) and 50 children (20 males, 30 females; median age, 3.5 years) with chronic diarrhea of unknown origin. All patients underwent a complete work-up to identify the causes of chronic diarrhea. FC was measured by ELISA.Results: In adult patients, FC showed 6…

Leukotriene receptor antagonists in monotherapy or in combination with antihistamines in the treatment of chronic urticaria: A systematic review

2008

In vitro and in vivo clinical and experimental data have suggested that leukotrienes play a key role in inflammatory reactions of the skin. Antileukotriene drugs, ie, leukotriene receptor antagonists and synthesis inhibitors, are a class of anti-inflammatory drugs that have shown clinical efficacy in the management of asthma and in rhinitis with asthma. We searched MEDLINE database and carried out a manual search on journals specializing in allergy and dermatology for the use of antileukotriene drugs in urticaria. Montelukast might be effective in chronic urticaria associated with aspirin (ASA) or food additive hypersensitivity or with autoreactivity to intradermal serum injection (ASST) wh…

Endothelial function and other biomarkers of cardiovascular risk in frequent consumers of street food.

2012

Summary Background & aims Street food (SF) is defined as out-of-home food consumption, and generally consists of energy dense meals rich in saturated fats, and poor in fibers, vitamins and anti-oxidants. Though SF consumption may have unfavorable metabolic and cardiovascular effects, its possible association with endothelial function has not been considered. Methods Participants were recruited among those who took part in a previous study of ours, done in Palermo, Italy, which investigated the association between consumption of SF and health in 1002 people. In that study, a score of SF consumption was obtained by categorizing each of ten foods consumed less than or more than once a month (0…

Phenotypic variation in hyperandrogenic women influences the findings of abnormal metabolic and cardiovascular risk parameters.

2005

In hyperandrogenic women, several phenotypes may be observed. This includes women with classic polycystic ovary syndrome (C-PCOS), those with ovulatory (OV) PCOS, and women with idiopathic hyperandrogenism (IHA), which occurs in women with normal ovaries. Where other causes have been excluded, we categorized 290 hyperandrogenic women who were seen consecutively for this complaint between 1993 and 2004 into these three subgroups. The aim was to compare the prevalence of obesity, insulin resistance, and dyslipidemia as well as increases in C-reactive protein and homocysteine in these different phenotypes with age-matched ovulatory controls of normal weight (n = 85) and others matched for body…

Psychological and behavioural factors associated with long-term weight maintenance after a multidisciplinary treatment of uncomplicated obesity

2013

Obesity is a multifactorial syndrome and the likelihood of success of a medical nutritional treatment (MNT) over the long term is low. As psychological and behavioural factors have an important role in both pathogenesis and the treatment of obesity, these issues were investigated in individuals with obesity who reported a long-term success or a failure in terms of weight loss following a MNT. Eighty-eight individuals of an original cohort of 251 subjects were re-evaluated 10 years after a MNT with cognitive-behavioural approach for uncomplicated obesity. Fifty-three participants were classified as failure (body weight change ≥0.5 kg) and 35 as a success (10-year body weight change <0.5 kg) …

Atherogenic lipoprotein phenotype and LDL size and subclasses in women with gestational diabetes.

2008

AIMS: Women with gestational diabetes are more likely to develop Type 2 diabetes and cardiovascular disease after pregnancy; however, the exact nature of the lipid alterations present is not clear. In Mediterranean women with gestational diabetes, we measured low-density lipoprotein (LDL) size and all seven subclasses, as well as the 'atherogenic-lipoprotein phenotype'[ALP, e.g. concomitant presence of elevated triglycerides, reduced high-density lipoprotein (HDL)-cholesterol and increased small, dense LDL]. METHODS: In 27 women with gestational diabetes and 23 healthy pregnant women matched for age, weeks of gestation and body mass index, we measured plasma lipids and LDL size and subclass…

Atherogenic lipoprotein phenotype and LDL size and subclasses in drug-naïve patients with early rheumatoid arthritis.

2009

Abstract Objective : Subjects with rheumatoid arthritis (RA) have increased cardiovascular risk and may show atherogenic forms of dyslipidemia. The present study investigated whether patients with early RA, beyond alterations in plasma lipids, also show lower LDL size and altered LDL subclass distribution. Design and Methods We identified 25 subjects with RA (47±8 years, body mass index (BMI) 25±4kg/m 2 ) by the American College of Rheumatology diagnostic criteria, with a disease durations Results As compared to controls RA patients had higher plasma triglycerides (1.8±0.5 vs. 1.0±0.5mmol/L, p p =0.0027), while total- and LDL-cholesterol concentrations were similar. LDL particle size was lo…

OBJECTIVE: To evaluate the role of social and cultural differences inside the same ethnic group on the ovulatory status of women with polycystic ovary syndrome (PCOS). DESIGN: To correlate social and cultural status with the phenotypic expression (body weight and ovulation) and with androgen and insulin levels of PCOS. SETTING: University department of medicine. PATIENT(S): Two hundred and forty-four consecutive PCOS women. INTERVENTION(S): All studied patients completed a simple questionnaire to indicate their mean family income and their school education. MAIN OUTCOME MEASURE(S): Ovulation was assessed by measurement of serum progesterone on day 22 of a spontaneous or induced menstrual cy…

The differential effects of thiazolidindiones on atherogenic dyslipidemia in type 2 diabetes: what is the clinical significance?

2008

Diabetic dyslipidemia is typically characterized by an increase in plasma triglycerides, a decrease in high-density lipoprotein cholesterol and a concomitant increase in atherogenic small dense low-density lipoproteins. Thiazolidindiones are able to lower the levels of fasting glucose and glycated hemoglobin significantly by improving insulin sensitivity, as well as improving some aspects of diabetic dyslipidemia: total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol tend to increase while triglycerides are generally decreased.This paper reviewed the effects of pioglitazone and rosiglitazone on atherogenic diabetic dyslipidemia, in particular on sma…

Similarity and differences in elderly patients with fixed airflow obstruction by asthma and by chronic obstructive pulmonary disease

2008

SummaryBackgroundEpidemiologic studies have demonstrated that elderly patients with fixed airflow obstruction can be affected by asthma or chronic obstructive pulmonary disease (COPD).MethodsWe studied 49 consecutive elderly outpatients, presenting fixed airflow obstruction, by clinical history (smoking), pulmonary function tests, blood gas analysis, and induced sputum.ResultsThe age was not different in patients with COPD (n=28) and asthma (n=21) (70.2±3.9 years vs. 69.6±3.7 years), also the degree of fixed airflow obstruction was similar (FEV1: 58.3±1.5% vs. 59.0±1.4% of predicted). Patients with asthma had significantly more eosinophils in peripheral blood (0.43±0.05×10−3μL vs. 0.27±0.1×…

Statins, Fracture Risk, and Bone Remodeling: What Is True?

2006

Besides the action on plasma lipid levels, statins show a series of ancillary effects defined as all of their vascular and nonvascular effects independent from the cholesterol reduction. It has been recently hypothesized that one of these ancillary effects could be the improvement of bone health, due to the interference with bone metabolism. This may potentially represent the rationale for statins' use in the treatment of osteoporosis, the most common disease of the bone. Both experimental observations and clinical studies on this topic generated a number of conflicting results; however, the largest randomized clinical trials, the Scandinavian Simvastatin Survival Study (4S), Long Term Inte…

New Insight into Immunity and Immunopathology of Rickettsial Diseases

2011

Human rickettsial diseases comprise a variety of clinical entities caused by microorganisms belonging to the generaRickettsia,Orientia,Ehrlichia, andAnaplasma. These microorganisms are characterized by a strictly intracellular location which has, for long, impaired their detailed study. In this paper, the critical steps taken by these microorganisms to play their pathogenic roles are discussed in detail on the basis of recent advances in our understanding of molecularRickettsia-host interactions, preferential target cells, virulence mechanisms, three-dimensional structures of bacteria effector proteins, upstream signalling pathways and signal transduction systems, and modulation of gene exp…

V?9V?2 T lymphocytes activation in osteoporotic patients treated with bisphosphonates

2014

Treatment with bisphosphonates induces differentiation and activation of Vγ9Vδ2 T lymphocytes obtained from peripheral blood showing also an antitumoral effect in both in vitro and in vivo models. Aim of the present study was to determine in vivo the effect of BPs treatment in patients affected with osteoporosis on Vγ9Vδ2 T lymphocytes. We have studied Vγ9Vδ2 T lymphocytes expansion and differentiation from PBMC obtained from osteoporotic patients treated with one of the following bisphosphonates zoledronate, alendronate, neridronate or risedronate. We have found that zoledronic acid, followed by alendronate was the most effective on reducing CM population (100%) and increasing TEM and TEMR…

How should we manage atherogenic dyslipidemia in women with polycystic ovary syndrome?

2007

Despite their young age, women with polycystic ovary syndrome (PCOS) have increased cardiovascular risk. Besides normal concentrations of low-density lipoprotein (LDL) cholesterol, dyslipidemia is very common and includes elevated triglyceride levels and low high-density lipoprotein cholesterol concentrations. Recent findings also showed that women with PCOS have qualitative LDL alterations, with increased levels of atherogenic small, dense LDL particles. Such lipid abnormalities constitute a common form of dyslipidemia, the so-called atherogenic lipoprotein phenotype (ALP), associated with a greater cardiovascular risk. Weight reduction and increased physical activity may constitute first-…

2005

One of the most promising genetic approaches to dissecting a multifactorial disease is represented by genetically isolated population studies. We studied a genetic marker in a cohort of women living on the Mediterranean island of Lampedusa, a geographically isolated population. Lampedusa, located between the African coast and Sicily, consists of a young genetic isolate (<20 generations) with an exponential growth in the last generations. We analyzed the association between the FokI vitamin D receptor (VDR) gene polymorphism, previously proposed as a predictor of bone mass, with parameters of bone mass and turnover in a cohort of pre- and postmenopausal women living on Lampedusa. In 424 wome…

Glucose lowering and anti-atherogenic effects of incretin-based therapies: GLP-1 analogues and DPP-4-inhibitors

2009

Type 2 diabetes is a chronic, progressive disease with a multi-faceted pathophysiology. Beyond the known defects of insulin resistance and beta-cell insufficiency, derangement of incretin hormones normally produced from the gut wall in response to food intake play an important role. In recent years, the 'incretin-based' therapies (IBTs) have been developed to address hyperglycemia through either mimicking the action of the endogenous incretin glucagon-like polypeptide (GLP-1) (GLP-1 receptor agonists) or by inhibiting the activity of the enzyme that degrades GLP-1 (the dipeptyl peptidase-4 inhibitors).We reviewed available evidence on the glucose lowering and anti-atherogenic effects of IBT…

Therapeutic patient education in oncology: pedagogical notions for women's health and prevention.

2007

Therapeutic patient education has been defined by the World Health Organization as a comprehensive approach to support patients and their families to better understanding of their diseases. In oncology, the contribution of therapeutic education may enable the patients to have adequate information of the illness, to actively participate in the management of the disease, to understand how to live with the illness, to learn how to face the critical moments of the clinical course, and to live in harmony with all health professionals. In addition, there may be several advantages for health professionals: a reduction in emotional labour, increased professional satisfaction, and a reduction in the…

Should we measure routinely oxidised and atherogenic dense low-density lipoproteins in subjects with type 2 diabetes?

2010

Beyond low-density lipoprotein (LDL)-cholesterol concentrations, in recent years, several clinical studies have shown that both oxidised and small, dense LDL have a strong predictive role for the presence of vascular atherosclerosis. These two lipid parameters seem to have a synergistic impact on cardiovascular risk, with a greater importance in patients at higher-risk, such as those with type-2 diabetes. Increased levels of oxidised and small, dense LDL levels are a feature of diabetic dyslipidaemia, and small, dense LDL have been shown to be a good predictor of future cardiovascular events, at both univariate and multivariate analyses. On the other hand, although the association of oxidis…

Long-term consequences of polycystic ovary syndrome on cardiovascular risk

2009

Most available data suggest that the prevalence of cardiovascular diseases in women with polycystic ovary syndrome (PCOS) is smaller than expected based on risk calculations during fertile years; therefore, more studies are needed on long-term cardiovascular consequences. Evidence is accumulating that postmenopausal women with PCOS have an increased risk of cerebrovascular events and cardiovascular morbidity. These events are partially related to persisting hyperandrogenism but are mostly correlated with excessive body weight (mainly visceral obesity); this suggests that our best long-term strategy is to ensure that women with PCOS are informed about their high risk for metabolic and cardio…

Clinical course of rhinitis and changes in vivo and in vitro of allergic parameters in elderly patients: a long-term follow-up study

2012

Changes in rhinitis symptom severity tend to decrease with aging, but whether the decrease is associated with allergic skin test reactivity, serum total and specific IgE, and nasal eosinophils or determined only by aging is poorly understood. The aim of the study was to analyze sensitivity in vivo and in vitro some 15 years after primary testing, skin prick test (SPT), serum total and specific IgE, ratio sIgE/tIgE, and nasal eosinophils in order to evaluate changes due to age and changes due to the severity of rhinitis symptoms. One hundred and eight rhinitis patients who had been investigated in 1995 were re-interviewed and their current allergy re-assessed after a follow-up of 15 years. A…

The effects of ezetimibe on LDL-cholesterol: quantitative or qualitative changes ?

2009

Ezetimibe represents the first of a new class of agents, the cholesterol absorption inhibitors, able to reduce low-density lipoproteins (LDL)-cholesterol by 15-25% from baseline in monotherapy and on top of statins and fibrates. To-date all the data regarding the efficacy of ezetimibe comes from the studies of its lipid-lowering power. Yet, recent findings from the ENHANCE study on atherosclerosis progression showed that the addition of ezetimibe to simvastatin in patients with heterozygous familial hypercholesterolemia did not affect the mean change in carotid intima-media thickness, although a significant reduction in LDL-cholesterol levels was present. Therefore, we cannot exclude that e…

Activin A circulating levels in patients with bone metastasis from breast or prostate cancer

2006

Recent studies have highlighted that Activin A, a member of the transforming growth factor-beta (TGF-beta) superfamily, may be involved in the regulation of osteoblastic activity and in osteoclast differentiation. Therefore, we have investigated the clinical significance of its circulating levels in patients with bone metastasis. Activin A serum concentrations were determined, by a commercially available enzyme-linked immunosorbent assay kit, in 72 patients with breast cancer (BC) or prostatic cancer (PC) with (BM+) or without (BM-) bone metastases, in 15 female patients with age-related osteoporosis (OP), in 20 patients with benign prostatic hypertrophy (BPH) and in 48 registered healthy b…

PREVALENCE OF ANTIBODIES ANTI-BARTONELLA HENSELAEIN WESTERN SICILY: CHILDREN, BLOOD DONORS, AND CATS

2011

To evaluate seroprevalence of B. henselae infection both in Sicilian children and healthy blood donors. Furthermore, circulation of Bartonella in the natural reservoir was also studied. Two hundred forty-three children, living in Sicily (Palermo), affected by various diseases, without clinical features suggesting B. henselae infection, together with 122 healthy blood donors were serologically investigated for IgG and IgM antibodies by indirect fluorescent antibody test (IFAT). One hundred twenty stray and 62 pet cats were also analyzed only for IgG. Among children 25.1% had IgG antibodies to B. henselae; 18.5% showed a titer 1:64, 2.4% 1:128, 2.4% 1:256, 0.8% 1:512, 0.4% 1:1024, and 0.4% 1:…

Correlation between different degree and duration of metabolic control and thyroid hormone levels in type 1 and type 2 diabetics.

1983

Thyroxine (T4), triiodothyronine (T3), reverse T3 (rT3) and HbA1c were assayed in 21 insulin-dependent (type 1) diabetics and in 45 non-insulin-dependent (type 2) diabetics with normal thyroid function and different levels of control, and were compared to values found in apparently healthy controls. rT3 and rT3/T3 ratio were significantly increased both in type 1 and type 2 diabetics. T3 and T4 were significantly lower in type 2 diabetics than in the controls. Significant positive correlations of HbA1c to rT3 (r = 0.63) and to rT3/T3 ratio (r = 0.53) were found in type 1, and in type 2 diabetics (HbA1c, rT3-r = 0.50), (HbA1c, rT3/T3-r = 0.37). There was no correlation between glycemia (BG),…

Effects of hypolipidemic and hypoglycemic agents on atherogenic small, dense LDL in Type 2 diabetes

2011

Type 2 diabetes is associated with a cluster of inter-related plasma lipid and lipoprotein abnormalities, including reduced HDL-C, a predominance of small, dense LDL and elevated triglycerides. These abnormalities occur even in prediabetes, before blood sugars rise sufficiently in order to confirm a diagnosis of diabetes, and this transition phase incurs important cardiovascular risk. This is the rationale for paying attention to dyslipidemia through the use of the hypolipidemic, rather than hypoglycemic drugs only. A literature search (by Medline and Scopus) was performed. The authors also manually reviewed the references of selected articles for any pertinent material. Beyond the ‘quantit…

Optimal duration of low molecular weight heparin for the treatment of cancer-related deep vein thrombosis. The ”CANCER DACUS” study

2014

Purpose We evaluated the role of residual vein thrombosis (RVT) to assess the optimal duration of anticoagulants in patients with cancer who have deep vein thrombosis (DVT) of the lower limbs. Patients and Methods Patients with active cancer and a first episode of DVT treated with low molecular weight heparin (LMWH) for 6 months were eligible. Patients were managed according to RVT findings: those with RVT were randomly assigned to continue LMWH for an additional 6 months (group A1) or to discontinue it (group A2), and patients without RVT stopped LMWH (group B). The primary end point was recurrent venous thromboembolism (VTE) during the 1 year after disconinuation of LMWH, and the secondar…

Correlation between osteoporosis and cardiovascular disease

2014

Several evidences have shown in the last years a possible correlation between cardiovascular diseases and osteoporosis. Patients affected with osteoporosis, for example, have a higher risk of cardiovascular diseases than subjects with normal bone mass. However, the heterogeneous approaches and the different populations that have been studied so far have limited the strength of the findings. Studies conducted in animal models show that vascular calcification is a very complex mechanism that involves similar pathways described in the normal bone calcification. Proteins like BMP, osteopontin, osteoprotegerin play an important role at the bone level but are also highly expressed in the calcifie…

High prevalence of polycystic ovary syndrome in women with mild hirsutism and no other significant clinical symptoms

2010

Objective To verify the conclusions of the Endocrine Society Guidelines that patients with mild hirsutism and no other important clinical signs (menstrual irregularities, infertility, central obesity, acanthosis nigricans, rapid progression of the hirsutism, clitoromegaly) should not be further studied. Design Retrospective study in patients referred because of mild hirsutism and no other clinical signs. Setting Department of Clinical Medicine of the University of Palermo. Patient(s) One hundred fifty-two patients with mild hirsutism.

Oligo-antigenic diet in the treatment of chronic anal fissures. Evidence for a relationship between food hypersensitivity and anal fissures.

2013

Abstract OBJECTIVES: Patients with chronic constipation due to food hypersensitivity (FH) had an elevated anal sphincter resting pressure. No studies have investigated a possible role of FH in anal fissures (AFs). We aimed to evaluate (1) the effectiveness of diet in curing AFs and to evaluate (2) the clinical effects of a double-blind placebo-controlled (DBPC) challenge, using cow's milk protein or wheat. METHODS: One hundred and sixty-one patients with AFs were randomized to receive a "true-elimination diet" or a "sham-elimination diet" for 8 weeks; both groups also received topical nifedipine and lidocaine. Sixty patients who were cured with the "true-elimination diet" underwent DBPC cha…

The predictive role of atherogenic dyslipidemia in subjects with non-coronary atherosclerosis

2009

Abstract Background Recent findings have suggested that subjects with non-coronary atherosclerosis may show elevated prevalence of atherogenic dyslipidemia, including higher triglyceride levels, reduced HDL-cholesterol concentrations and increased levels of small, dense low-density lipoproteins (LDL). These three lipid abnormalities constitute the so-called “atherogenic-lipoprotein-phenotype” (ALP) but its predictive role in these patients still remains to be established. Methods We performed a 2-year follow-up study to assess clinical and biochemical predictors of cardiovascular events in 44 male patients (64 ± 5 years, BMI: 27 ± 3), 26 with peripheral arterial disease and 18 with abdomina…

MALIGNANT TUMOR-LIKE GAASTRIC LESION DUE TO CANDIDA ALBICANS IN A DIABETIC PATIENT TREATED WITH CYCLOSPORIN: A CASE REPORT AND REVIEW OF THE LITERATU…

2012

The gastrointestinal tract of healthy individuals is colonized by hundreds of saprophytes and mycetes, especially the Candida species, are habitual ones. Under certain conditions, the fungal flora may overgrow, resulting in lesions of the digestive mucosa which, rarely, can have a local diffusion and/or spread to the lympho-hematogenous system. Mycotic infections of the stomach can sometimes look like benign gastric ulcers. Here, we present the case report of a woman, aged 64, who presented with type II diabetes mellitus and psoriasis, on chronic treatment with cyclosporin A and with endoscopic evidence of an ulcerated, vegetating gastric lesion secondary to Candida albicans infection. Alth…

Interleukin-18 levels are associated with low-density lipoproteins size

2009

INTRODUCTION: Both low-density lipoproteins (LDL) size and serum interleukin (IL)-18 levels have been shown to be predictors of cardiovascular morbidity and mortality. However, it is still unknown whether IL-18 levels are independently associated with LDL size. METHODS: In this cross-sectional study including 53 premenopausal women (18-45 years), LDL size (by gradient gel electrophoresis), serum IL-18, high-sensitivity C-reactive protein (hs-CRP), serum lipids, insulin sensitivity (S(I), by frequently sampled intravenous glucose tolerance test) were measured. RESULTS: LDL size correlated with IL-18 (r = -0.38, P = 0.006), hs-CRP (r = -0.40, P = 0.003), S(I) (r = 0.36, P = 0.011), serum trig…

Circulating levels of adipose products and differences in fat distribution in the ovulatory and anovulatory phenotypes of polycystic ovary syndrome.

2009

Central fat distribution is increased in anovulatory women with polycystic ovary syndrome (PCOS) compared with ovulatory PCOS and matched controls. Among secreted adipocytokines, this is reflected mainly in lower levels of adiponectin.

Randomized placebo-controlled trial comparing desloratadine and montelukast in monotherapy and desloratadine plus montelukast in combined therapy for…

2004

BACKGROUND: H 1 -receptor antagonists are considered to be particularly effective in reducing pruritus, and they are therefore recommended as first-line treatment in patients with chronic idiopathic urticaria (CIU). Recently, antileukotriene receptors have been used in patients with CIU, either administered as monotherapy or combined with H 1 -receptor antagonists. OBJECTIVE: We compared the clinical efficacy of 5 mg of desloratadine administered once daily either as monotherapy or combined with a leukotriene antagonist, 10 mg of montelukast daily, and 10 mg of montelukast administered daily as monotherapy for the treatment of patients affected by CIU with placebo. METHODS: One hundred sixt…

Effect of CYP1A1 Gene Polymorphisms on Estrogen Metabolism and Bone Density

2004

UNLABELLED: In this study, we evaluated the effect of polymorphisms of the CYP1A1 gene, linked to hormone-related cancers, on estrogen metabolism and BMD. We found that variants carrying the A allele (CA and AA) for the C4887A polymorphism have a significantly higher degree of estrogen catabolism and lower femoral BMD. INTRODUCTION: Polymorphisms of the CYP1A1 gene, one of the key enzymes that metabolize estrogen, have been linked with hormone-related cancers. We investigated the impact of these polymorphisms on estrogen metabolism and BMD, which is another hormone-dependent health issue. MATERIALS AND METHODS: One hundred seventy postmenopausal women (mean age, 63.5 +/- 0.6 years) particip…

Evaluation of serum s-IgE/total IgE ratio in predicting clinical response to allergen-specific immunotherapy.

2009

Background: To date, no predictive tests for the clinical response to allergen-specific immunotherapy (ASI) are available. Therefore an in vivo or in vitro test would be of great value. Objective: We sought to evaluate pretreatment parameters used in diagnosing allergic rhinitis and determining serum specific IgE (s-IgE) levels, serum total IgE (t-IgE) levels, and blood eosinophil counts and to identify whether can be used to predict clinical improvement in monosensitized patients with allergic rhinitis with or without asthma treated with immunotherapy. Methods:We analyzed 279 patients who had undergone 4 years of ASI administered either by means of the subcutaneous immunotherapy (76 patien…

Heat Shock Protein-60 and Risk for Cardiovascular Disease

2011

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. There is growing evidence that molecularchaperones, many of which are heat shock proteins HSPs, are involved in CVD pathogenesis. In this review we focus on HSP60,the human mitochondrial chaperone that also displays extramitochondrial and extracellular functions. HSP60 is typically cytoprotectivebut a number of stress conditions determine its conversion to a potentially toxic molecule for cells and tissues. We present illustrative examplesof specific subtypes of CVD where HSP60 is implicated in the initiation and/or progression of disease. The data not only indicatea pathogenic role for HSP60 but also its …

Predicting efficacy and toxicity in the era of targeted therapy: focus on anti-EGFR and anti-VEGF molecules

2011

The treatment of solid malignancies includes various target drugs, such as monoclonal antibodies and tyrosine kinase inhibitors, which exert their effect alone or in combination with chemotherapy. The main part of these molecules have a target on proteins of EGFR and VEGF pathways. The particular toxicity profile and the financial impact, deriving from the application of these agents in cancer treatment, prompted a lot of researches to define predictive factors of their efficacy. Various biomarker were identified among the components of the targeted pathways. However just few studies allowed to identify specific factors to predict the toxicity of these drugs. In this review EGFR and VEGF-re…

Is there a role for antileukotrienes in urticaria?

2006

In vitro and in vivo clinical and experimental data have suggested that leukotrienes play a key role in inflammatory reactions of the skin. Antileukotriene drugs, i.e. leukotriene receptor antagonists and synthesis inhibitors, are a new class of anti-inflammatory drugs that have shown clinical efficacy in the management of asthma. We searched the MedLine database and carried out a manual search on journals specializing in allergy and dermatology for the use of antileukotriene drugs in urticaria. Montelukast might be effective in chronic urticaria associated with aspirin or food additive hypersensitivity or with autoreactivity to intradermal serum injection when taken with an antihistamine b…

Two novel mutations at exon 8 of Sequestosome 1 gene (SQSTM 1)in an Italian series of patient affected by Paget’s disease of bone (PDB)

2004

PDB is genetically heterogeneous. Mutations of the sequestosome1 gene have been reported in sporadic and familial forms of Paget's in patients of French Canadian and British descent. Mutational analyses in different ethnic groups are needed to accurately investigate hereditary diseases. We describe two novel mutations of sequestosome1 in 62 Italian sporadic patients, confirming the role of the encoded protein in this disorder. INTRODUCTION: Paget's disease of bone (PDB) is a relatively common disease of bone metabolism reported to affect up to 3% of whites over 55 years of age. The disorder is genetically heterogeneous, and at present, there is scientific evidence that at least eight differ…

Endothelial abnormalities in young women with PCOS: correlations with insulin resistance and decreased levels of serum adiponectin

2006

Abstract PURPOSE: Polycystic ovary syndrome (PCOS) is an extremely prevalent disorder in which elevated blood markers of cardiovascular risk and altered endothelial function have been found. This study was designed to determine if abnormal carotid intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) in young women with PCOS may be explained by insulin resistance and elevated adipocytokines. METHODS: A prospective study in 50 young women with PCOS (age: 25.2 +/- 1 years; body mass index [BMI]: 28.7 +/- 0.8) and 50 matched ovulatory controls (age: 25.1 +/- 0.7 years; BMI: 28.5 +/- 0.5) was performed. Carotid IMT, brachial FMD, and blood for fasting glucose, insulin, leptin, …

Food-additive-induced urticaria: a survey of 838 patients with recurrent chronic idiopathic urticaria

2005

&lt;i&gt;Background:&lt;/i&gt; Recurrent chronic idiopathic urticaria (RCIU) is a common skin condition that affects 0.1–3% of the population in the USA and Europe and accounts for nearly 75% of all ‘ordinary’ chronic urticaria (CU) cases. &lt;i&gt;Methods:&lt;/i&gt; We studied 838 consecutive patients with RCIU referred to hospital between 1998 and 2003. Patients with known causes of CU were excluded. Clinical history, physical examination, and symptom diaries were evaluated during two periods, a diet-free period (1 week) and a food-additive-free diet (FAFD) period (4 weeks), respectively, and two double-blind placebo-controlled (DBPC) challenges of six food additives were administered.

PREVALENCE OF DIASTOLIC DYSFUNCTION IN PATIENTS WITH ARTERIAL HYPERTENSION AND CHRONIC KIDNEY DISEASE

2013

Introduction: In patients with arterial hypertension and chronic kidney disease (CKD), the prevalence of diastolic heart failure (HF-PEF) is probably very high. However, in these patients the diagnosis is difficult, especially because the signs and symptoms suggestive of HF-PEF are very common in CKD; in these cases the detection of left ventricular structural and functional alterations (as reported in the 2012 ESC guidelines on heart failure), assumes a decisive role for the diagnosis of HF-PEF. Aim: To evaluate the prevalence of patients with diastolic dysfunction according to ESC guidelines 2012 in a population of Hypertensive patients with CKD. Methods: We studied 466 hypertensive patie…

The Val432Leu polymorphism of the CYP1B1 gene is associated with differences in estrogen metabolism and bone density.

2009

Polymorphisms of the CYP450 genes that encode for the enzymes that metabolize estrogen are linked to hormone-related cancers. We investigated the impact of two polymorphisms of the CYP1B1 gene previously reported to be associated with hormone-related disorders on estrogen metabolism and bone mineral density (BMD), another hormone-dependent condition, in women from different ethnic backgrounds. Four hundred sixty-eight postmenopausal Caucasian women, 220 from St. Louis, MO, USA (mean age=63.5±0.53 years) and 248 from Palermo, Italy (mean age=72.9±0.44 years) participated in the study.

ASSOCIATION OF SERUM URIC ACID WITH AORTIC STIFFNESS IN UNTREATED HYPERTENSIVE SUBJECTS.

2013

INTRODUCTION: Recent studies have reported an association between serum uric acid (SUA) and reduced arterial elasticity. However, in these studies arterial elastic properties have been assessed chiefly by measuring brachial-ankle pulse wave velocity (PWV) or peripheral PWV and only sometimes by using aortic PWV, that is considered the gold standard for measuring arterial stiffness. Moreover, the studies exploring the influence of SUA on aortic distensibility in subjects with arterial hypertension yielded conflicting results. AIM: The purpose of our study was to evaluate the relationships between SUA and aortic stiffness in a group of essential hypertensive patients. METHODS: We enrolled 222…

Relationship between aortic stiffness and serum uric acid in essential hypertension

2012

In last years hyperuricemia has been associated with an increased incidence of renal and cardiovascular events in general population, as well as in patients with diabetes and hypertension. However, the role of serum uric acid (SUA) as independent cardiovascular risk factor is still controversial. It is well known that increased aortic stiffness is a powerful independent predictor of cardiovascular events. Little is known about the influence of uric acid on aortic distensibility in subjects with arterial hypertension. The aim of our study was to evaluate the relationships between SUA and aortic stiffness in a group of essential hypertensive patients, attending our Hypertension Centre. We enr…

GERD in the elderly: an endoscopic experience.

2013

Analyzing medical issues related to the elderly patients, particularly in the gastroenterological sphere, Gastro-Esophageal Reflux Disease (GERD) seems to be a disease that reaches an important role in terms of diagnosis and therapy, as well as adversely affect the quality of life of these “frail” patients. Comorbidities that affect these patients often lead to reduce the importance of this disease, which in fact, not infrequently, it is difficult to identify because of mild symptom picture compared to younger patients. Is important to remember that GERD, although in most cases provokes only vague dyspeptic symptoms, can also lead to serious complications, such as bleeding especially in pat…

Autoimmune liver disease in a sicilian woman.

2012

Autoimmune hepatitis (AIH) is a chronic liver disease characterized by clinical features analogue to viral and non-autoimmune liver disorders, but with distinct sero-autoimmunologic properties. The disease results from a network of complex interactions involving genetic predisposition, triggering factors, autoantigens and immunoregulatory system. Diagnosis of AIH relies on positive autoantibodies determination and on liver core biopsy histological appearance. Corticosteroid and immunosuppressive drugs are generally useful in the treatment of disease. However, when inflammation cannot be controlled, progression from chronic hepatitis to cirrhosis is often observed and hepatocellular carcinom…

2004

Urticaria and angioedema will affect 15-20% of the general population during their lifetime, and this remains one of the most vexing conditions to evaluate and treat. This review of the literature is to give the reader a global insight into the spectrum of urticaria and angioedema, focusing on differential diagnosis and pathogenic mechanisms. It will define the role of the mast cell, exploring a possible autoimmune basis for urticaria. Last, the different potential treatments will be discussed. Urticaria and angioedema are frustrating problems for both physicians and their patients; however, the problem may best be approached by considering urticaria as a general affection rather than a spe…

THE BIA VECTOR IN OBESITY AND DIABETES

2013

Although the assessment of body water compartments is of great diagnostic value, appropriate methods are not readily available for routinely clinical application. Bioelectrical impedance analysis (BIA) is a safe, noninvasive, rapid and highly reproducible procedure that is strongly influenced by body water and intra-/extracellular distribution. Four-hundred-fifty-six adults (224 males and 232 females) were enrolled and divided in subgroups on the basis of the presence of obesity and diabetes (type 1 and type 2). The aim of the study was to investigate if different BIA measurements in terms of resistance (R), reactance (Xc) and phase angle (PA) were associated to these conditions. Plotting t…
