AB0266 METHOTREXATE AND CARDIOVASCULAR RISK IN RHEUMATIC DISEASES:A COMPREHENSIVE REVIEW
2021
Background:The management of inflammatory rheumatic disease has evolved in the last decade with the importance of the management of comorbidities. Methotrexate is the cornerstone of inflammatory rheumatic disease management, but its cardiovascular effects are still poorly understoodObjectives:To assess the cardiovascular impact of methotrexate in inflammatory rheumatic disease.Methods:A systematic review of the literature, following the prisma recommandations, was performed on the PubMed and Embase databases with the following keywords: (“Methotrexate”) AND (“cardiovascular”). We included papers written in English and including patients older than 18 years.Results:570 references were identi…
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…
The importance of diagnosing the Polycystic Ovary Syndrome
2000
The polycystic ovary syndrome (PCOS) is an extremely common disorder that occurs in 4% to 7% of women of reproductive age. Although PCOS is known to be associated with reproductive morbidity and increased risk for endometrial cancer, diagnosis is especially important because PCOS is now thought to increase metabolic and cardiovascular risks. These risks are strongly linked to insulin resistance and are compounded by the common occurrence of obesity, although insulin resistance and its associated risks are also present in nonobese women with PCOS. Women with PCOS are at increased risk for impaired glucose tolerance, type 2 diabetes mellitus, and hypertension. Cardiovascular disease is believ…
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…
Platelet membrane fluidity and platelet membrane lipid pattern in essential hypertension
1995
In a group of subjects with essential hypertension platelets were studied in resting conditions: platelet membrane fluidity was measured with the fluorescent probe 1.4-(trimethylamino)-phenyl-4-phenylhexatriene (TMA-DPH), platelet membrane cholesterol/phospholipid ratio was evaluated separating the membrane lipids with column chromatography, and platelet membrane individual phospholipids were determined using two-dimensional thin-layer chromatography. From the obtained results, it is evident that platelet membrane fluidity does not differentiate normals from hypertensives; platelet membrane cholesterol/phospholipid ratio is increased in hypertensives, while of the platelet membrane individu…
Chapter 23: Choline, a precursor of acetylcholine and phospholipids in the brain
1993
Publisher Summary The plasma level of free choline is remarkably constant at about 10 pM in animals and human. Ingestion of food, especially when rich in choline or lecithin, transiently elevates the plasma choline level up to 20 pM or more. In contrast, choline-deficient diet leads to a reduction of the plasma level by about 50%. Choline is considered an essential nutrient, which is predominantly supplied as phosphatidylcholine (lecithin). For a long time, neuroscientists have been intrigued by the fact that choline is a precursor for the biosynthesis of both acetylcholine (ACh) and phospholipids. For 50 years, lecithin has been marketed in Europe as a drug that was claimed to prevent exha…
Antiphosphatidylserine Antibodies Affect Rat Yolk Sacs in Culture: a Mechanism for Fetal Loss in Antiphospholipid Syndrome
2004
PROBLEM: A variety of reproductive impairments have been reported in the context of the antiphospholipid syndrome (APS). APS is associated with the presence of antibodies to negatively charged phospholipids that may affect the outcome of pregnancy. METHOD OF STUDY: Rat embryos were cultured within their yolk sacs. The effects of two antiphosphatidylserine monoclonal aPS antibodies (HL5B, RR7F) regarding their influence on growth and apoptotic events of the yolk sacs, as well as on growth and the morphology of the embryos, were studied. RESULTS: Exposure of rat embryos and their yolk sacs to aPS inhibited yolk sac growth. Moreover, increased number of apoptotic events of giant cells in the a…
The LDL receptor in the retina: the missing link in aging, the new target in dietary prevention
2012
National audience; Purpose: The discovery of the LDL receptor (LDLR) in 1985 by Brown and Goldstein was awarded by a Nobel Prize. The LDLR has initially been identified for its role in mediating the endocytosis of LDL particles in the vascular endothelium. The deposition of lipids, including cholesterol and cholesteryl esters in Bruch’s Membrane in the one hand, and in the vessel intima in the other hand, is one of the common features of age related macular degeneration (AMD) and cardiovascular disease (CVD). Dietary habits with high intakes of omega 3 long chain fatty acids (LCFA) have been associated with AMD prevention. Similar effects have been demonstrated in CVD prevention. The mechan…

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…
