light chain myeloma induced severe hypertriglyceridemia

Hyperlipidemia is very common in general population and incidence has further increased in recent years. Evaluation of patient presenting with lipid disorders is essential to obtain a definite diagnosis to prevent complications, and apply the most appropriate treatment. An isolated elevation in triglyceride levels may be caused by a primary disorder of lipid metabolism like familial hypertriglyceridemia. It may also arise secondary to a number of conditions like diabetes mellitus, alcohol intake, hypothyroidism, drugs, infections and nephrotic syndrome. Herein, we describe a case of secondary hypertriglyceridemia leading to Nonalcoholic Steatohepatitis (NASH) in a young female which was attributed to Multiple Myeloma (MM). Significant reduction in triglyceride levels after starting anti-myeloma therapy established their relation. This is the first case of light chain myeloma causing severe secondary hypertriglyceridemia.
