Abstract

Henoch-Schönlein purpura nephritis (HSPN) is one of the most common types of chronic glomerulonephritis in children; however, there have been few reports on the pathogenesis and management of grade VI HSPN. We present the case of a 6-year-old boy with grade VI HSPN accompanied by severe nephrotic syndrome and hypocomplementaemia. Immunohistological studies revealed profound glomerular accumulation of CD45- and CD68-positive inflammatory cells. Moreover, some cells expressed the proliferating marker proliferating cell nuclear antigen. His proteinuria and general oedema persisted despite repeated high-dose steroid therapy; however, these clinical symptoms immediately improved after beginning treatment with cyclophosphamide (CYP). Grade VI HSPN was successfully treated with steroids and immunosuppressants. Among immunosuppressive drugs, CYP was considered the most effective.
