The prevalence of metabolic syndrome is high in hemodialysis. MS is defined by the combination of high blood pressure, dyslipidemia, central obesity and a state of insulin resistance. The aim of this work is to see if there's a difference by gender in the different parameters of metabolic syndrome and in cardiovascular morbidity in our hemodialysis patients. It is a cross-sectional study of 120 patients older than 18 years on hemodialysis. The metabolic syndrome was defined according to the criteria of the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III). A comparison by gender was performed for the following parameters: age, diabetes, hypertension, obesity, dyslipidemia, coronary artery disease and heart failure. Forty chronic hemodialysis patients with metabolic syndrome have been the subject of this study. The sex ratio was 1.88 and the mean age was 55.97 years. Seventy percent had diabetes and 90% were hypertensive. Coronary artery disease was present in 57.5% of cases and heart failure in 52.5% of cases. The study by gender showed no significant difference except for the prevalence of hyper LDL cholesterol. There is a high prevalence of cardiovascular complications in men but a significant difference by gender could not be demonstrated.

Obesity is a cardiovascular risk factor in the general population. However, obesity on hemodialysis is associated with better survival. The aim of this study is to determine the prevalence of obesity in our chronic hemodialysis population and to specify the different cardiovascular complications. It is a cross-sectional study with 120 patients older than 18 years on hemodialysis. Abdominal obesity was defined as waist circumference > 94 cm in men and > 80 cm in women. The following were analyzed: socioeconomic and demographic parameters, lifestyle, initial renal disease, duration of hemodialysis, food consumption and body mass index (BMI), biological parameters (C-reactive protein (CRP), albumin, lipid profiles, serum calcium, phosphorus, parathyroid hormone), comorbidities: Diabetes, hypertension, stroke, coronary artery disease. Twenty-four patients had a BMI> 25. The prevalence of abdominal obesity was 20%. The sex Ratio was 0.71. The average age of our patients was 55.97 years [23-78 years]. Reduced physical activity was observed in 75% of patients. Duration in hemodialysis was 79 months. Hemoglobin (Hb) average was 8.9 g/dl, serum calcium was 2.25 mmol/l, serum phosphorus was 1.7 mmol/l, parathyroid hormone (PTH) was 412 pg/ml, albuminemia was 30.7 g/l, total cholesterol was 3.75 mmol/l and CRP was 15 U/l. Coronary artery disease was found in 20.8% of cases, stroke in 8.3% of cases, diabetes in 58.33% of cases and hypertension in 75% of cases. There was a high prevalence of abdominal obesity in hemodialysis patients. Obesity is recognized by its association with increased risk of cardiovascular disease and mortality. However in the paradoxical epidemiology, obesity becomes in chronic hemodialysis, a protective factor and is associated with better survival. Our study has a small population and cannot reach such a conclusion; further studies with larger numbers are needed to support this concept.
