Differences in the behavior of advanced glycation end products and advanced oxidation protein products in patients with allergic rhinitis

2013

BACKGROUND: The presence of oxidative stress in patients with asthma is well documented; however, the role of oxidative stress in allergic rhinitis has received less attention, although it is likely to be similar to that observed in patients with asthma. Advanced glycation end products (AGEs) and advanced oxidation protein products (AOPPs) are compounds formed by the transformation of macromolecules, including proteins, which can serve as densitometric markers of oxidative stress and inflammation in several diseases. OBJECTIVE: The aim of this study was to investigate the role of AGEs and AOPPs as new markers of oxidative stress and inflammation in patients affected by allergic rhinitis. ME…

The effect of age on mitogen responsive T cell precursors in human beings is completely restored by interleukin-2.

1992

Abstract It is well known that the function of T lymphocytes is significantly impaired by advancing age. In the present study, attempts have been made to further characterize the T cell impairment of elderly subjects. Thus, we have performed limiting dilution microculture analysis to evaluate the precursor frequency of T lymphocytes responding to a mitogenic stimulus in old and young subjects. Furthermore we have evaluated the activity of recombinant interleukin-2 (rIL-2) on these cells. The results demonstrate that in older subjects the frequency of these precursors is significantly decreased. The in vitro treatment with rIL-2 increased the frequency of mitogen responsive T lymphocyte prec…

Efficacy and safety of allergen immunotherapy in patients with allergy to molds: A systematic review

2018

BACKGROUND Allergen immunotherapy (AIT) with mould extracts has been performed for many years but the final demonstration of its clinical efficacy is still missing, due to the small number of studies and their inconsistent results. OBJECTIVE To systematically review efficacy and safety of AIT for the treatment of respiratory allergies to moulds. DESIGN The primary outcomes were safety and reduction of symptoms (Symptom Score, SS) and medication use (Medication Score, MS) in patients treated with AIT compared to controls. The strength of the evidence was graded based on the risk of bias, consistency and magnitude of effect, according to the GRADE Working Group's guide. DATA SOURCES Medline, …

Age-related changes in the expression of CD95 (APO1/FAS) on blood lymphocytes☆

1999

Abstract Aging is associated with alterations of the immune system, thought to be related to an increased susceptibility to infectious diseases, and possibly to cancer and autoimmunity in the elderly. In the present paper we report data obtained on freshly collected blood from 148 healthy subjects of different ages (from cord blood to 102 years old). The subjects were divided into seven age classes (cord blood, 3–11 years, 15–39 years, 41–60 years, 61–74 years, 75–84 years, 85–102 years) and their lymphocyte subsets and the expression of the apoptosis-related molecule CD95 were evaluated. In respect of lymphocyte subsets, the major differences were found in the cord-blood samples compared w…

2006

Background. HLA genes play a role in the predisposition of several diseases. The aim was to analyze the prevalence of HLA class I phenotypes and HLA-DRB1*genotype in patients with CIU associated with ASA and NSAIDs hypersensitivity (AICU).Methods. 69 patients with AICU, and 200 healthy subjects.Results. 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…

Apoptosis and ageing.

1998

Stimulation of T cells from aged individuals leads to different kinds and/or size of responses if compared with the responses of T cells obtained from young individuals. In fact elderly is associated with a progressive decline of immune response besides an increasing incidence of autoimmune phenomena. These differences might be the result of modified cellular mechanisms controlling the immune system in the course of ageing. The apoptotic deletion of activated T cells has been proposed as the key mechanism to maintain T cell homeostasis, and in this respect CD95 (Fas antigen) seems to play a major role in this course of events. In this study we show that just collected lymphocytes from old s…

The model developed was validated using the data set obtained from another medical institution. Methods The analysis was performed using a database obtained from a questionnaire administered to the patients with nasal symptoms containing personal data, clinical data, and results of allergy testing (SPT). All variables found to be significantly different between patients w…

The effect of allergen immunotherapy in the onset of new sensitizations: a meta-analysis

2017

Background Although the preventive efficacy of allergen immunotherapy (AIT) in the onset of new allergen sensitizations has been asserted by many reviews, position papers, and consensus conferences, the evidence available is from only 3 studies. The objective of this work was a systematic review to evaluate the preventive efficacy of AIT in the onset of new allergen sensitizations. The end-point was the risk difference (RD) in the onset of new allergen sensitizations between patients treated with AIT and pharmacotherapy. Methods Computerized bibliographic searches of MEDLINE, EMBASE, and the Cochrane Library (until November 30th, 2016) were done. Random-effects and fixed-effects model meta-…

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…

2006

BACKGROUND: Desquamative gingivitis (DG) is a clinical condition characterized by red, painful, glazed, and friable gingiva, which might be a manifestation of some autoimmune mucocutaneous diseases. The time from the development of initial signs of DG to diagnosis can vary from months to years. Based on a literature search, no data concerning patients with DG without signs of autoimmune disease were available. OBJECTIVE: The aim of this trial was to compare the efficacy and tolerability of monotherapy with topical tacrolimus 0.1% in pectin ointment versus clobetasol propionate 0.5% ointment in adults affected by DG. METHODS: This randomized, double-blind clinical trial was conducted at the …

A study of serum immunoglobulin levels in elderly persons that provides new insights into B cell immunosenescence.

2007

The literature on immunosenescence has focused mainly on T cell impairment. With the aim of gaining insight into B cell immunosenescence, we investigated the serum immunoglobulin levels in a cohort of 166 subjects (20-106 years). Serum IgG (and IgG subclasses) were quantified by the nephelometric technique, IgE by CAP system fluorescence enzyme immunoassay, and IgD by radial immunodiffusion (RID). There was an age-related increase of IgG and IgA; the IgG age-related increase was significant only in men, but IgG1 levels showed an age-related increase both in men and women, whereas IgG3 showed an age-related increase only in men. IgE levels remain unchanged, whereas IgD and IgM serum levels d…

Efficacy of subcutaneous and sublingual immunotherapy with grass allergens for seasonal allergic rhinitis: a meta-analysis–based comparison

2012

Background: Subcutaneous (SCIT) and sublingual (SLIT) immunotherapy are the 2 most prescribed routes for administering allergen-specific immunotherapy. They were shown to be effective in control of symptoms and in reducing rescue medication use in patients with allergic diseases, but their effectiveness has to be balanced against side effects. In recent years, SLIT has been increasingly prescribed, instead of SCIT, because of improved safety and easy administration. Objective: We assessed which route is the most effective in the treatment of patients with seasonal allergic rhinitis to grass pollen. Methods: An indirect meta-analysis–based comparison between SCIT and SLIT was performed. Trea…

Prevalence of organ-specific and non organ-specific autoantibodies in healthy centenarians.

1997

In the present study we have investigated the prevalence of organ-specific and non organ-specific autoantibodies in 26 healthy centenarians (6 men, 20 women; age range 101-106 years), using as controls 54 healthy old (33 men and 21 women, age range 71-93) and 56 young subjects (29 men and 27 women, age range 26-60). We assayed sera of each group for the following organ-specific autoantibodies, anti-gastric mucosa (anti-PCA), anti-thyroglobulin (anti-Tg) and non organ-specific autoantibodies, anti-cardiolipin (anti-APA IgG and IgM), anti-nuclear antigens (anti-ANA), anti-double strand DNA (anti-ds-DNA), anti-extractable nuclear antigens (anti-ENA). Finally, natural anti-alpha-galactosyl (ant…

Prevalence of Sensitization toAnisakis simplexAmong Professionally Exposed Populations in Sicily

2012

Anisakis simplex (AS) is a cause of allergic sensitization and potential occupational risk is suggested in fishermen and workers assigned to fish processing and sale. A cross-sectional study was conducted in order to assess possible health effects of occupational exposure to AS in workers recruited from western Sicily fisheries sector. Social, demographic, and occupation-related data were collected. Serum total immunoglobulin E (IgE) and specific IgE levels to AS (threshold >0.35 kU/L) were determined by an fluoroimmunoassay technique. Ninety-four subjects with potential occupational exposure (fishmongers, fishermen, fish industry employees) were recruited. Specific AS IgEs were detected in…

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…

In vitro treatment with interleukin-2 normalizes type-1 cytokine production by lymphocytes from elderly

2000

The term immunosenescence is taken to mean the deterioration of immune function seen in elderly, which is manifested in increased susceptibility to infectious diseases, neoplasias, and autoimmune diseases. It is only recently that we have begun to understand the cellular and molecular changes involved. Of special interest in this regard are observations of a decline in synthesis of Type-1 cytokines which predisposes to diminished cell mediated immunity. We have evaluated the production of type 1 cytokines in old and young donors either in presence or in absence of recombinant interleukin-2 (rIL-2). Lymphocytes were stimulated with plastic bound anti-CD3 and after 48 h the supernatants were …

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…

Assessment of a qualitative serological assay to screen for allergic sensitization in elderly subjects

2013

We used a commercially available specific IgE qualitative serological assay to screen for allergic sensitization. Two hundred twenty-eight elderly subjects took part in the study. Skin-prick tests (SPTs) to a panel of relevant aeroallergens present in the study area were used as the diagnostic reference procedure (gold standard). Subjects with at least one positive SPT (≥3 mml n = 76) were considered to have developed an allergic sensitization. The qualitative assay correctly classified subjects as sensitized to an allergen or not sensitized in 257 of 288 cases (accuracy, 88.9%; 95% CI, 85.0-92.0%). The qualitative assay sensitivity was 70.0 (95% CI, 58.1-79.7) and specificity was 95.7 (95%…

Memory B Cell Subpopulations in the Aged

2006

The literature on immunosenescence has focused mainly on T cell impairment. With the aim of gaining insight into B cell immunosenescence, the authors investigated the serum IgD levels in 24 young and 21 old people and analyzed their relationship with the number of CD19 CD27 memory cells. Serum IgD were quantified by the use of radial immunodiffusion and the lymphocyte population CD19 CD27 was identified by a FACScan flow cytometer. Serum IgD levels were significantly lower (p 0.0001) in old subjects, and the percentage of CD19 CD27 lymphocytes were significantly increased (p 0.01) in old subjects. Finally, a significant negative correlation was found (p 0.01) between serum concentrations of…

Efficacy of Grass Pollen Allergen Sublingual Immunotherapy Tablets for Seasonal Allergic Rhinoconjunctivitis: A Systematic Review and Meta-analysis.

2015

IMPORTANCE: Randomized clinical trials (RCTs) and meta-analyses of sublingual immunotherapy (SLIT) for the treatment of seasonal allergic rhinoconjunctivitis (SARC) have shown a modest clinical benefit compared with placebo. Furthermore, indirect comparison by meta-analyses showed that subcutaneous immunotherapy is more effective than SLIT. Despite these data, SLIT has become the most prescribed treatment of SARC in Europe in recent years, and it was approved by the US Food and Drug Administration for the treatment of SARC to grass pollen in the United States on April 1, 2014. OBJECTIVE: To assess the efficacy and safety of the grass pollen sublingual tablets licensed as drugs in the treatm…

Comparison between statistical and fuzzy approaches for improving diagnostic decision making in patients with chronic nasal symptoms

2014

This paper compares a fuzzy model, expressed in rule-form, with a well known statistical approach (i.e. logistic regression model) for diagnostic decision making in patients with chronic nasal symptoms. The analyses were carried out using a database obtained from a questionnaire administered to 1359 patients with nasal symptoms containing personal data, clinical data and skin prick test (SPT) results. Both the fuzzy model and the logistic regression model developed were validated using a data set obtained from another medical institution. The accuracy of the two models in identifying patients with positive or negative SPT was similar. This study is a preliminary step to the creation of a so…

Additive Effects of Salmeterol and Fluticasone or Theophylline in COPD

2000

ss(2)-Agonists and corticosteroids or theophylline can interact to produce beneficial effects on airway function in asthma, but this has not been established in COPD.Eighty patients with well-controlled COPD were randomized to receive 3 months of treatment in one of four treatment groups: (1) salmeterol, 50 microg bid; (2) salmeterol, 50 microg, plus fluticasone propionate, 250 microg bid; (3) salmeterol, 50 microg, plus fluticasone propionate, 500 microg bid; and (4) salmeterol, 50 microg, plus titrated theophylline bid. At each visit, a dose-response curve to inhaled salbutamol was constructed using a total cumulative dose of 800 microg.A gradual increase in FEV(1) was observed with each …

Polymorphisms of cyclo-oxygenases and 5-lipo-oxygenase-activating protein are associated with chronic spontaneous urticaria and urinary leukotriene E4

2011

The mechanisms of chronic spontaneous urticaria (CSU) continue to be unknown. Our working hypothesis is that polymorphisms of cyclo-oxygenases and 5-lipo-oxygenase-activating protein may be involved in the pathways leading to CSU. We examined five candidate polymorphisms of cyclo-oxygenases 1 and 2 and of 5-lipo-oxygenase-activating protein in 109 controls and in 94 CSU patients from Northern Italy. We also examined the levels of urinary leukotriene E4 (LTE4) before and after challenge with ASA. A multiple regression model was found to show that COX-2 5'UTR T/G, COX-2 Exon 10 T/C, and FLAP -336 G/A polymorphisms were significantly associated with CSU, with the minor allele more represented …

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…

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×…

Granulocyte and natural killer activity in the elderly

1999

The deterioration of the immune system in ageing, 'immunosenescence', is thought to contribute to increased morbidity and mortality from infections and possibly autoimmune diseases and cancer. The most profound changes involve effector and immunoregulatory T-cell functions. Immunosenescence appears also to be related to changes in non specific immunity as well. In the present study we have assessed superoxide production, chemotaxis and the expression of the apoptosis-related molecule APO1/Fas (CD95) on neutrophils (PMN) from young and old subjects. Furthermore, we have measured the basal natural killer (NK) activity of young and elderly subjects and we have compared the number of CD16+ cell…

Circulating levels of soluble adhesion molecules in patients with ANCA-associated vasculitis

2004

BACKGROUND: During inflammation, activated vascular endothelial cells and other cell types express various adhesion molecules, which facilitate the binding of circulating leukocytes and their extravasation in surrounding tissue (i.e. renal tissue). The serum concentration of circulating soluble adhesion molecules is supposed to reflect the degree of this activation. OBJECTIVE: In the first part of the study, we determined if the serum levels of the soluble intercellular adhesion molecule (sICAM)-1 and the soluble endothelial cell-leukocyte adhesion molecule (sELAM)-1, in patients affected by microscopic polyangiitis (MPA), associated with myeloperoxidase (MPO)-anti-neutrophil cytoplasmic an…

A study of age-related IgE pathophysiological changes.

2003

Abstract The literature on immunosenescence has focused mainly on T cell impairment. However, it is well known that B function is also profoundly affected. In particular, several studies have shown age-related changes in immunoglobulin serum levels. Concerning allergic diseases, the incidence of onset of allergic symptoms, as well as their severity, seems to decrease with age. So, the decline of onset of allergic symptoms observed in ageing might result from a decrease of serum total IgE due to an unbalance of cytokines and soluble factors involved in its production. To gain insight into the mechanisms of age related incidence of onset of allergic symptoms, as well as their severity, in thi…

Chronic Urticaria as a presenting symptom of Crohn’s disease.

2009

Clinical presentation of Crohn’s disease (CD) may be variable according to the location and the intensity of the inflammation. Some patients may have atypical symptoms which could delay the diagnosis. We report the first case of chronic urticaria related to a subclinical, complicated CD. Although the pathologic mechanism of this association was unclear in our patient, this case suggests that in patients with unexplained chronic urticaria it is opportune to investigate for a possible CD, even if there are no or few specific symptoms of intestinal inflammatory disease.

Measurement of inflammatory mediators of mast cells and eosinophils in native nasal lavage fluid in nasal polyposis.

2001

<i>Background:</i> Nasal polyposis (NP) often coexists with asthma, rhinitis and sinusitis. Polyp histology typically shows chronic, eosinophilic inflammation. The inflammatory cell infiltrate generally includes eosinophils, lymphocytes, plasma cells and mast cells. <i>Objective:</i> To gain insight into the natural history of NP, we analysed mediator levels and leukocyte values in nasal fluids and eosinophil cationic protein (ECP), total IgE levels and eosinophils in the blood in several groups of both allergic and non-allergic patients with nasal polyps and in patients with allergic rhinitis (AR). <i>Methods:</i> Thirty-two patients with nasal polyps en…

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…

Comparative effect of tacrolimus 0.1% ointment and clobetasol 0.05% ointment in patients with oral lichen planus.

2008

Background Oral lichen planus (OLP) is considered to be an autoimmune disease of unknown aetiology that affects the mucosae, especially the oral cavity. Objective We compared tacrolimus 0.1% ointment and clobetasol 0.05% ointment for the treatment of OLP. Patients and methods A total of 32 patients (20 females and 12 males; all white, Italian origin, mean age of 43.6+/-18.4 years; 16 patients per treatment group) were treated with tacrolimus or clobetasol ointment for 4 weeks in a randomized, double-blind, clinical trial. Pain severity, burning sensation, and mucosal lesion extension were assessed using a four-point scale. Results At the end of the treatment period, symptom scores were sign…

Interleukin-5 production by mononuclear cells from aged individuals: implication for autoimmunity.

1999

It is well known that in the elderly a deterioration of immune functions may occur. Particularly, stimulation of T cells from aged individuals leads to different kind and/or size of responses if compared with the responses obtained from T cells from young individuals. At the same time, an increase in prevalence of autoantibodies occurs in elderly. The altered production of certain cytokines might explain this paradox of decreased responsiveness to foreign antigens in the face of an increased response to self-antigens. We and others have suggested that this kind of immune response might depend on an age-associated impairment of Th-1 type function that selectively affects production of cytoki…

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…

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…

Biological Basis of the HLA-B8,DR3-Associated Progression of Acquired Immune Deficiency Syndrome

1998

The factors influencing the evolution of human immunodeficiency virus (HIV) infection are not fully known, but the host genotype undoubtedly plays a role in determining the outcome of the disease by affecting the immune response to HIV. The role of the host human leukocyte antigen (HLA) genotype in the regulation of susceptibility to HIV infection and expression has been studied extensively in different major risk groups. Certain HLA alleles and haplotypes, being associated with aberrant immune responses independently from HIV infection, have been reported to facilitate the rapid progression of disorders related to HIV infection. Particularly, the association of rapid acquired immunodeficie…

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…

Food allergy in gastroenterologic diseases: Review of literature

2007

Food allergy is a common and increasing problem worldwide. The newly-found knowledge might provide novel experimental strategies, especially for laboratory diagnosis. Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the “gold standard” for diagnosis of food allergy, shows that questionnaire-based studies overestimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or nonimmunologic mechanisms and the organ system or systems affected. Diagnosis of food allergy is based on clini…

Among human rickettsial diseases caused by micro-organisms of the genus Rickettsia (Order Rickettsiales; Family Rickettsiaceae), transmitted to human hosts through arthropod vectors, Mediterranean Spotted Fever, or Boutonneuse Fever, and Rocky Mountain Spotted Fever are considered to be important infectious diseases due to continued prevalence in the developed world, and potentially fatal outcome in severe cases. Proliferation of rickettsiae, at the site of the tick bite, results in focal epidermal and dermal necrosis (tache noire). Rickettsiae then spread via lymphatic vessels to the regional lymph nodes, and, via the bloodstream, to skin, brain, lungs, heart, liver, spleen and kidneys. Th…

Identificazione e Prevenzione delle allergie indoor

2023

L’inquinamento può essere definito come la presenza di un eccesso di elementi nell’ambiente con conseguenti effetti dannosi per la salute. Può assumere la forma di sostanze chimiche o di energia, come rumore, calore o luce. Può contaminare l’aria, il suolo e l’acqua, e può provenire da contaminanti naturali o da attività di ingegneria umana. Si stima che nel 2015 l’inquinamento abbia causato la morte di 9 milioni di persone in tutto il mondo, di cui l’inquinamento atmosferico (AP) domestico è stato responsabile di 2.9 milioni di morti. L’AP riguarda sostanze emesse al di sopra dei livelli ammissibili nell’aria ambiente ed è generato da emissioni solide (particolato), liquide o gassose. In b…

Interleukin-12 release by mitogen-stimulated mononuclear cells in the elderly.

1998

Abstract Defects involving cellular expression of activation molecules, cell mediated immune response and natural killer (NK) activity are commonly observed in the elderly. Herein, data are reported on the evaluation of IL-12 production by old subjects. IL-12 is, actually, considered the key molecule for the induction of a T helper 1 (Th1) -type and NK response. IL-12 production from old subjects peripheral blood mononuclear cells (PBMNC) was evaluated using T-independent (bacterial lipopolysaccharide, LPS) or -dependent (phytoemagglutinin, PHA; immobilized anti-CD3 monoclonal antibodies, anti-CD3) mitogens. The IL-12 production after LPS stimulation was not reduced in cultures from old sub…

Bronchial reactivity and intracellular magnesium: a possible mechanism for the bronchodilating effects of magnesium in asthma

1998

1.Increased bronchial smooth muscle contractility with consequent bronchial hyperreactivity are characteristic physiopathological events of asthma. Since magnesium intervenes in calcium transport mechanisms and intracellular phosphorylation reactions, it constitutes an important determinant of the contraction/relaxation state of bronchial smooth muscle. In the present study we investigated the relationship between bronchial reactivity, assessed by methacholine-provocation test, and magnesium concentrations both at extracellular and intracellular levels measured by spectrophotometry. Twenty-two patients with mild-to-moderate asthma and 38 non-asthmatic subjects with allergic rhinitis (24 all…

Aspetti psicologici e strategie di coping nella dialisi e nel trapianto renale

2006

Aim. Although with different results, dialysis and kidney transplantation represent two effective strategies in treating chronic uraemia. Our study compares the psychological aspects of two categories of patients: on one hand those who faced kidney transplantation and have been in dialysis, on the other hand the non complaint patients treated with these therapies. Methods. We used a test for the analysis of the personality (MMPI2) and the COPE, that tests the abilities to coping used by the patient in certain conditions that can be perceived us stressful or, in any case, as unusual. With both MMPI2 and COPE we tested 120 patients that have faced haemodialysis and 50 that have been subject t…

A Case of Fatal Drug Rash Eosinophilia and Systemic Symptoms from Allopurinol

2015

Hypereosinophilia is a systemic condition that has several possible etiologies: allergies, medications, infectious, autoimmune or other systemic diseases, and finally idiopathic forms. Skin involvement seems to relate to subcutaneous inflammatory infiltration in this condition, as can be observed in parasitic, autoimmune and bullous diseases, as well as in drug reactions. Generalizing, a severe adverse drug-induced reaction may cause a systemic inflammatory disease: Drug Rash with Eosinophilia and Systemic Symptoms (DRESS). Its diagnosis requires the application of a complex diagnostic algorithm and immediate identification to prevent inauspicious evolution. The prognosis is severe; drug di…

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

2005

<i>Background:</i> 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. <i>Methods:</i> 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. Th…

Introduction: The significance of the association between allergic rhinitis and abnormal airway responsiveness is unclear. For this reason, we have studied, in patients with seasonal allergic rhinitis, non specific bronchial hyperreactivity, total serum IgE and blood eosinophils, with reference to the responsible allergen, during and out of the pollen season. Materials and methods: Fourty-nine, non-smoking patients, living in Palermo, with clinical diagnosis of allergic rhinitis, skin prick tests and specific serum IgE mono-sensitive to pollen allergens, were enrolled in the study. Twenty patients suffered from seasonal rhinitis to Parietaria pollen, 15 patients to Graminacee pollen and 14 …

Rickttsial disease: classical and modern aspects

2004

Rickettsial diseases have been reassessed in recent years since they represent an important field in today's medicine. New agents have been described: some are non-pathogenic agents and the others are associated with well-defined or peculiar clinical patterns. In addition, different species of rickettsiosis are found in relation to the geographic areas of the world. Some agents may be defined as variants of older diseases whereas most of the newly described forms of rickettsiosis represent distinct entities with unique epidemiologial and clinical features. Probably the main news regards the group of the spotted fevers. An additional new aspect is linked to the medicine of travellers and tou…

The effect of allergen immunotherapy in the onset of new sensitizations: a meta-analysis.

2017

Background Although the preventive efficacy of allergen immunotherapy (AIT) in the onset of new allergen sensitizations has been asserted by many reviews, position papers, and consensus conferences, the evidence available is from only 3 studies. The objective of this work was a systematic review to evaluate the preventive efficacy of AIT in the onset of new allergen sensitizations. The end-point was the risk difference (RD) in the onset of new allergen sensitizations between patients treated with AIT and pharmacotherapy. Methods Computerized bibliographic searches of MEDLINE, EMBASE, and the Cochrane Library (until November 30th, 2016) were done. Random-effects and fixed-effects model meta-…

Di Lorenzo1 1University of Palermo, Palermo, Italy Background: Several epidemiological studies demonstrate that a timeline from rhinitis to asthma exists, and that rhinitis is a risk factor for asthma. In particular, rhinitis increases the chance of development of asthma by about three times. In addition to environmental factors, genetic factors play an important role in the development of atopic airway diseases. The aim of this study is to analyse the role of cytokine polymorphism in the evolution of rhinitis-asthm…

Aspetti psicologici in dialisi e nei pazienti non collaboranti

2005

L’emodialisi e la dialisi peritoneale, anche se rappresentano (con il trapianto) la terapia sostitutiva d’elezione dell’insufficienza renale, non sempre vengono vissute positivamente dai pazienti, a causa delle rigide prescrizioni terapeutiche e per i cambiamenti che apportano nella vita quotidiana (1,2). Ciò potrebbe incidere negativamente sulla non compliance che è definita, in entrambi i trattamenti, come l’inosservanza parziale o totale della terapia, che può essere associata alla non accettazione del trattamento sostitutivo (3). In letteratura viene stimato che il 50% dei pazienti in emodialisi ed un terzo di quelli in peritoneale abbia almeno una parziale non compliance che nella magg…

Prevalence of Sensitization to Anisakis simplex Among Professionally Exposed Populations in Sicily

2012

Anisakis simplex (AS) is a cause of allergic sensitization and potential occupational risk is suggested in fishermen and workers assigned to fish processing and sale. A cross-sectional study was conducted in order to assess possible health effects of occupational exposure to AS in workers recruited from western Sicily fisheries sector. Social, demographic, and occupation-related data were collected. Serum total immunoglobulin E (IgE) and specific IgE levels to AS (threshold >0.35 kU/L) were determined by an fluoroimmunoassay technique. Ninety-four subjects with potential occupational exposure (fishmongers, fishermen, fish industry employees) were recruited. Specific AS IgEs were detected in…

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…
