Relapsing Henoch-Schonlein purpura associated with Pseudomonas aeruginosa pyelonephritis

Henoch-Schonlein purpura is a systemic vasculitis of unknown cause. It is f requently triggered by a streptococcal upper respiratory tract infection. O ther bacteria have been implicated as triggering agents. We report a recurr ing case of Henoch-Schonlein purpura in a patient with Pseudomonas pyelonep hritis. The Henoch-Schonlein purpura remitted only when the infection was e radicated. Pseudomonas infection should be added to the list of bacteria th at can trigger Henoch-Schonlein purpura.
