Abstract

Weight loss is common in systemic immunoglobulin light chain amyloidosis but there are limited data on the impact of nutritional status on outcome. Using the Patient-Generated Subjective Global Assessment (PG-SGA) score, we prospectively examined nutritional status in 110 consecutive newly-diagnosed, treatment-naïve patients with immunoglobulin light chain amyloidosis attending the UK National Amyloidosis Centre. At study entry, 72 of 110 (66%) patients had a PG-SGA score of 4 or over, indicating malnutrition requiring specialist nutritional intervention. Number of amyloidotic organs, elevated alkaline phosphatase, presence of autonomic neuropathy and advanced Mayo disease stage were independently associated with poor nutritional status (P<0.05). Quality of life was substantially poorer among those with higher PG-SGA scores (P<0.001). Furthermore, PG-SGA score was a powerful independent predictor of patient survival (P=0.02). Malnutrition is prevalent and is associated with poor quality of life and reduced survival among patients with systemic immunoglobulin light chain amyloidosis. The PG-SGA score would be an appropriate tool to evaluate whether nutritional intervention could improve patient outcomes.
