    Abstract:
    BACKGROUND: Calorie-protein malnutrition is associated with increased morbidity and mortality in hemodialysis patients. The aim of this study was to evaluate the prevalence of malnutrition in uremic patients treated with hemodialysis in two areas of Southern Italy. METHODS: A questionnaire was sent out to all Dialysis Centers in the two regions to select and enrol eligible patients by considering these parameters: Body Mass Index (BMI), serum albumin, serum creatinine, urea, calcium, phosphate, triglycerides, cholesterol, body weight. Enrolment criteria were patients on dialysis for at least six months and BMI less than 21 kg/m2. The dialytic dose was evaluated by reporting the hours of dialysis and filter surfaces. The number of weekly sessions (n. 3) remained unchanged over time. RESULTS: Twenty-three Dialysis Centers in the two Regions replied to our questionnaire and 149 patients were enrolled in the study out of the 1546 patients examined. The overall prevalence of calorie-protein malnutrition was observed in 9.6% of the patients. The prevalence of malnutrition was found to be higher in males and in patients on dialysis for longer time. We observed no correlation with the hypoproteic diet administered in the pre-dialysis phase. Malnourished patients showing progressive weight loss were older and had undergone dialysis for a longer time. CONCLUSIONS: This retrospective study indicates low prevalence of malnutrition in the two regions examined. The lack of correlation between the hypoproteic diet and dialytic dose suggests the need for further studies to evaluate if increased dialytic dose or early start of dialysis could improve the nutritional status and quality of life in elderly patients.
