Co-existing autosomal dominant polycystic kidney disease and nephrotic syndrome in a Nigerian patient with lupus nephritis

A little over 30 cases on co-existing nephrotic syndrome and autosomal dominant polycystic kidney disease (ADPKD) have been reported from different regions of the world since 1957. We present a case report on co-existence of nephrotic syndrome (secondary to lupus nephritis) with ADPKD in a 24-year-old woman from Nigeria. She was positive for anti-double stranded DNA. Renal histology showed International Society of Nephrology/Renal Pathology Society Class II lupus nephritis. The co-existence of nephrotic syndrome and ADPKD may have been overlooked in Africa in the past. There is a need to screen for nephrotic syndrome in patients with ADPKD among clinicians in the African setting.
