Minimal change disease following autologous stem cell transplant for Hodgkin lymphoma.

Abstract

Nephrotic syndrome is characterised by heavy proteinuria secondary to glomerular injury. It is an uncommon but serious complication of allogeneic haematopoietic stem cell transplant (HSCT), but rarely reported after autologous HSCT. Here, we report the case of a man in his mid-20s who presented with significant peripheral oedema 2 months after autologous HSCT for Hodgkin lymphoma. Investigations demonstrated nephrotic range proteinuria and hypoalbuminaemia. Renal biopsy demonstrated minimal change disease. Initial treatment with glucocorticoids was complicated by toxicity without remission. However, the clinical and biochemical resolution of his nephrotic syndrome promptly followed administration of rituximab. This case highlights nephrotic syndrome as a complication after autologous HSCT and suggests potential effectiveness of rituximab in minimal change disease in the presence of steroid toxicity or other contraindications.
