Phosphate binders, appetite and nutritional status in maintenance hemodialysis patients
摘要
Background and Objectives: The potential side effects of common phosphate binders are gastrointestinal in practice. We hypothesized that regular use of phosphate binders may be associated with decreased appetite, dietary intake and consequently, poor nutritional status. Methods and Study Design: This was cross-sectional study of 78 patients (mean age 67.5±13.0, 34.6% women) undergoing maintenance hemodialysis (MHD) treatment. Participants were divided into three equal groups - sevelamer (n=25), lanthanum (n=24) and the control group (n=29). Eating motivation was assessed using visual analogue scales (VAS) and by a self-reported appetite assessment which was graded on a 5-point Likert scale. Main outcome measure was differences in VAS scores for appetite, dietary intake and nutritional status (malnutrition-inflammation score [MIS]) in the study groups. Results: Appetite, dietary intake, biochemical nutritional markers, anthropometric measures and MIS were similar in the three groups. A statistically significant difference was observed in sensation of fullness between the groups: multivariable adjusted ORs in the sevelamer carbonate group was 4.90 (95% CI: 1.12 to 21.43), p=0.04 and in the lanthanum carbonate group was 5.18 (95% CI: 1.15 to 23.30), p=0.03 versus the control group. However, no linear association was observed between MIS scores and VAS scores for appetite in any study group. Conclusions: Regular use of these phosphate binders was not associated with anorexia, decreased dietary intake and nutritional status in the study population. Therefore, there is no preference in the choice of phosphate binders in MHD patients with hyperphosphatemia, even those who are at nutritional risk.
