title: [Evolution of nutritional status in hemodialysis patients during 4 years of follow].
abstract: Protein-calorie malnutrition as well as systemic inflammation and metabolic disorders are common among patients with chronic renal failure undergoing renal replacement therapy (hemodialysis), which contributes to their morbidity and mortality. This work has followed 90 patients of both sexes with chronic kidney disease who were treated with hemodialysis periodically in our unit for four years. All patients were performed quarterly measurements of plasma albúmina (A1b), total cholesterol (TC), total protein (TP) and monthly transferrin (Tr), Anthropometric measurements of height and weight were taken on all patients by using a balance/stadiometer (Perperson 113481); weight was measured in kilograms and height in centimetres. BMI was calculated with this formula: weight/height2 and classified according to the WHO criteria: BMI < 18.50: Underweight; from 18.50 to 24.99: Normal range; from 25.00 to 29.99: Overweight; and BMI > or =30.00: Obese. The aim of this work was evaluate the nutritional status of these patients through the assessment of biochemical parameters and anthropometric parameters and determine if these patients suffer alterations suggesting nutritional deterioration directly related to the time on dialysis. During the 4 years all patients showed a significant decline of biochemical parameters, on the other hand the BMI did not significant changes in relation to malnutrition. Malnutrition in patients on dialysis is therefore evident, the BMI does not correspond with the biochemical parameters observed, so nutritional deterioration of these patients is mainly manifested by biochemical parameters studied.
