Background
Nephrotic syndrome occurring as a complication of immune tolerance therapy for inhibitors in hemophilia B is well recognized. It is also known to occur in association with factor borne infections, especially hepatitis C. This is the first case report of nephrotic syndrome occurring in a child receiving prophylactic factor VIII in the absence of inhibitors of hepatitis infection. However, the pathophysiology of this phenomenon is poorly understood.
Case presentation
A 7-year Sri Lankan boy diagnosed with severe hemophilia A on weekly factor VIII prophylaxis was diagnosed with three episodes of nephrotic syndrome, a condition in which there is leakage of plasma protein into urine. He had three episodes of nephrotic syndrome, all of which responded well to 60 mg/m2 daily dose of oral steroids, achieving remission within 2 weeks of starting daily prednisolone. He has not developed inhibitors for factor VIII. His hepatitis screening remained negative.
Conclusions
There is a possible link between factor therapy for hemophilia A and nephrotic syndrome, which can be a T-cell-mediated immune response. This case also highlights the importance of monitoring for renal involvement in patients treated with factor replacement.
