Nephritis is observed in around 30% of children with Henoch–Schönlein purpura (HSP). The treatment of these patients is complicated by similarity to IgA nephropathy. Here, the authors discuss advances in understanding of the pathophysiology, diagnosis and treatment of paediatric HSP nephritis. They suggest that current treatment guidelines based evidence obtained in adults with IgA nephropathy might be inappropriate for children with HSP nephritis.
