Abstract
Lipoprotein glomerulopathy (LPG) is a rare condition of renal lipidosis characterized by lipoprotein thrombi in glomeruli, an abnormal plasma lipoprotein profile, and a marked increase in serum apolipoprotein E (apo E) levels. It is a monogenic disorder with autosomal dominant inheritance and the average age of presentation is 32 years (4-69 years). It is rare in children. The presentation can be nephrotic syndrome, hematuria, or progressive renal failure. Here we report the first described case of LPG in an Indian 7.5-year-old boy who presented with steroid-resistant nephrotic syndrome with normal renal function. A renal biopsy was suggestive of lipoprotein glomerulopathy. The detection of a pathogenic variant in apo E, Kyoto type, by exome sequencing, confirmed the diagnosis of lipoprotein glomerulopathy. Complete response was achieved with Angiotensin-converting Enzyme inhibitor and fenofibrates.
