Abstract

Background: Maintenance of a good nutritional status is associated with prolonged survival in many chronic diseases. To date, the nutritional status of outpatients with immunoglobulin light-chain (AL) amyloidosis has not been evaluated. Objective: The aims of this study were to obtain information regarding the nutritional status of AL amyloidosis outpatients and to investigate its prognostic role. Design: One hundred six consecutive patients with histologically confirmed AL amyloidosis were enrolled. Anthropometric, biochemical, and clinical variables were measured. The Kaplan-Meier method was used to calculate survival. A Cox proportional hazard model was constructed to evaluate the prognostic effect of the nutritional variables. Results: Unintentional weight loss (median: 11.3%; range: 2.6-34% of usual nonedematous body weight) was documented in 58 subjects (54.7%). Body mass index (BMI; in kg/m2) was
