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…
Triglycerides, HDL cholesterol and atherogenic dyslipidaemia in the 2019 European guidelines for the management of dyslipidaemias.
2019
In general, both European and American clinical guidelines have addressed the management of atherogenic dyslipidaemia in an unconvincing and even superficial way, largely because of the available therapeutic limitations. Consequently, this type of dyslipidaemia is underdiagnosed, under-treated, and under-controlled. Given the recent presentation of the 2019 guidelines of the European Atherosclerosis Society and the European Society of Cardiology on the management of dyslipidaemias, it seems appropriate to examine its position with respect to atherogenic dyslipidaemia and/or its main components, the increase in triglyceride-rich lipoproteins, and the decrease of high-density lipoprotein chol…
Association of Aldosterone and Cortisol with Cardiovascular Risk Factors in Prehypertension Stage
2012
Background. The Pakistani population has higher incidence of cardiovascular (CV) diseases at younger ages, due to undiagnosed, uncontrolled hypertension (HTN). A variety of associated HTN stressors is also reported. The study plans to understand the variables associated with initiation of HTN in this population.Objective. To find plasma aldosterone and cortisol relationship with some CV risk factors (obesity, dyslipidemia, hyperglycemia, sodium and potassium) in different stages of HTN particularly prehypertension.Subjects and Methods. The study conducted on 276 subjects (25–60 years), classified into prehypertensive (n=55), HTN stage-1 (n=70) and II (n=76) according to 7th JNC report and c…
0102: Atherogenic lipid profile and lipid peroxide products of patients with rheumatoid arthritis
2016
IntroductionRheumatoid Arthritis (RA) is a chronic relapsing immune-inflammatory multisystem disease with predominant synovial proliferation and destruction of articular cartilage. Patients with RA have a higher riskof mortality related to increased risk of cardiovascular disease with atherogenic lipid profile. In recent years, oxidative stress in RA patients has received considerable attention and has been implicated as mediators of tissue damage and cardio-vascular disease in patients with RA.The aim of the present study was to assess the lipid profile and lipid peroxide products of patients with rheumatoid arthritis compared with healthy controls.Patients and MethodsThe study included 70…
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…
The role of fibrate treatment in dyslipidemia: an overview.
2012
Dyslipidemia, and especially atherogenic dyslipidemia, a combination of small low-density lipoproteins cholesterol (LDL-C), decreased high-density lipoprotein cholesterol (HDL-C) and increased triglyceride (TG) concentrations, represents a major cardiovascular (CV) risk factor. Nuclear receptor peroxisome proliferator-activated receptors (PPARs) are involved in the regulation of lipid metabolism; PPAR ligands are used to treat dyslipidemias. Fibrates have a major impact on TG metabolism as well as on modulating LDL size and subclasses. Fibrates target atherogenic dyslipidemia by increasing plasma HDL-C concentrations and decreasing small dense LDL (sdLDL) particles and TGs, thus contributin…
Constitutive androstane receptor activation stimulates faecal bile acid excretion and reverse cholesterol transport in mice.
2010
The constitutive androstane receptor (CAR) is a nuclear receptor expressed in the liver and involved in xenobiotic metabolism. The aim of this study was to assess whether pharmacological CAR activation could affect neutral sterol and bile acid elimination under conditions of cholesterol overload.Wild type, Car-/-, ApoE-/-, and low-density lipoprotein receptor (Ldlr)-/- mice fed a western-type diet were treated with the CAR agonist TCPOBOP.CAR activation was associated with a decrease in faecal cholesterol output related to the repression of the Abcg5/g8 cholesterol transporters. In contrast, TCPOBOP treatment induced a marked increase (up to three fold, p0.01) in the elimination of faecal b…
Chronic kidney disease and dyslipidaemia
2016
Chronic kidney disease (CKD) has to be considered as a high, or even very high risk cardiovascular risk condition, since it leads to an increase in cardiovascular mortality that continues to increase as the disease progresses. An early diagnosis of CKD is required, together with an adequate identification of the risk factors, in order to slow down its progression to more severe states, prevent complications, and to delay, whenever possible, the need for renal replacement therapy. Dyslipidaemia is a factor of the progression of CKD that increases the risk in developing atherosclerosis and its complications. Its proper control contributes to reducing the elevated cardiovascular morbidity and …
Recent Updates and Advances in the Use of Glycated Albumin for the Diagnosis and Monitoring of Diabetes and Renal, Cerebro- and Cardio-Metabolic Dise…
2020
Diabetes mellitus is a heterogeneous and dysmetabolic chronic disease in which the laboratory plays a fundamental role, from diagnosis to monitoring therapy and studying complications. Early diagnosis and good glycemic control should start as early as possible to delay and prevent metabolic and cardio-vascular complications secondary to this disease. Glycated hemoglobin is currently used as the reference parameter. The accuracy of the glycated hemoglobin dosage may be compromised in subjects suffering from chronic renal failure and terminal nephropathy, affected by the reduction in the survival of erythrocytes, with consequent decrease in the time available for glucose to attach to the hemo…
Cholesterol and ocular pathologies: focus on the role of cholesterol-24S-hydroxylase in cholesterol homeostasis
2015
The retina is responsible for coding the light stimulus into a nervous signal that is transferred to the brain via the optic nerve. The retina is formed by the association of the neurosensory retina and the retinal pigment epithelium that is supported by Bruch’s membrane. Both the physical and metabolic associations between these partners are crucial for the functioning of the retina, by means of nutrient intake and removal of the cell and metabolic debris from the retina. Dysequilibrium are involved in the aging processes and pathologies such as age-related macular degeneration, the leading cause of visual loss after the age of 50 years inWestern countries. The retina is composed of severa…
