title: A case report of Henoch-Schoenlein purpura nephritis associated with a postbulbar duodenal ulcer.
abstract: We experienced an adult patient with Henoch-Schoenlein purpura (HSP) nephritis associated with a postbulbar duodenal ulcer. Chronic inflammatory changes of the arterioles (i.e. vasculitis) in the kidney and skin were prominently observed by immunofluorescence and light microscopic analysis. It is postulated that a postbulbar duodenal ulcer occurred in this patient and was mediated by vascular deposition of circulating immune complexes. It was suggested that HSP nephritis is a diffuse vascular form of IgA nephropathy.
