Background: Post-transplantation recurrence of primary focal and segmental glomerulosclerosis (FSGS) is estimated to occur in 30%-50% of cases and doubles the risk of allograft failure. Treatment of recurrent FSGS is challenging because specific pathogenic targets are unknown and available therapeutic options have limited efficacy.
Case report: We report a case of recurrent FSGS with nephrotic-range proteinuria (urine protein creatinine ratio [UPCR], >50) and debilitating edema that was resistant to rituximab and plasmapheresis. The patient had a remarkable response to adrenocorticotropic hormone (ACTH) gel and achieved complete remission (UPCR, 0.5; serum albumin, 4.1 g/dL; serum creatinine, 1.0 mg/dL) which was maintained over 10 months on this treatment.
Conclusions: We conclude that ACTH gel is a potential therapeutic option for post-transplantation recurrence of FSGS and warrants further evaluation.
