Background The influence of serum leptin levels on nutritional status and survival in chronic
hemodialysis patients remained to be elucidated. We conducted a prospective longitudinal
study of leptin levels and nutritional parameters to determine whether changes of serum
leptin levels modify nutritional status and survival in a cohort of prevalent hemodialysis
patients. Methods Leptin, dietary energy and protein intake, biochemical markers of nutrition
and body composition (anthropometry and bioimpedance analysis) were measured at …
