Lipoprotein glomerulopathy: a rare cause of steroid-resistant nephrotic syndrome in a child

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.
