Comparison of nutritional and hydration status in patients undergoing twice and thrice-weekly hemodialysis: a silent drama in developing countries.

Abstract：

PURPOSE:In low and middle- income countries, due to lack of financial resources, the number of patients receiving one or two hemodialysis (HD) sessions a week has increased, leading to a large number of complications. Protein-energy wasting (PEW) and overhydration (OH) are common complications; nevertheless, the evidence regarding the nutritional status of patients receiving 2 and 3 weekly dialysis sessions is scarce. Thus, our objective was to compare the nutritional and hydration status of patients with two and three HD sessions. Secondarily, we aimed to compare hospitalizations, infectious complications and mortality within the following 6 months after the initial assessment. METHODS:Forty-four patients in a 3 weekly session scheme and 44 dialyzed twice a week were included. Anthropometrical, biochemical, dietary and impedance measurements were performed. Malnutrition Inflammation Score (MIS) and PEW score were applied. Number of hospitalizations, infectious complications and mortality during the 6 months following the evaluation were recorded. RESULTS:Prevalence of moderate/severe undernutrition (63.6% vs 36.4%, p < 0.006) and prevalence of OH (90.9% vs 77.3%, p < 0.001) were significantly higher in the twice-weekly sessions group compared to the 3 weekly sessions. The twice a week session group showed a 3.7-fold (OR 3.7, 95% CI 1.3-10.5, p = 0.01), a 2.5-fold (OR 2.4, 95% CI 0.9-6.6, p = 0.01), a 4.5-fold (OR 4.5, 95% CI 1.0-20.2, p < 0.05), a 8.3-fold (HR 8.3, 95% CI 2.4-28.2, p = 0.001) and a 11.6-fold (HR 11.6, 95% CI 2.4-54.0, p = 0.002) increased odds of developing undernutrition, PEW, OH, being hospitalized or death, respectively, compared to those who received three sessions per week. CONCLUSIONS:Twice weekly hemodialysis scheme is associated with higher odds of moderate or severe undernutrition, PEW, OH status, hospitalization and mortality compared to a thrice-weekly hemodialysis scheme.
