Central venous catheter infection-induced Henoch-Schönlein purpura in a patient on hemodialysis.

A 69-year-old man, who had been dialyzed using a permanent central venous catheter for 2 years, presented with Henoch-Schönlein purpura and positive perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA). He was diagnosed with catheter-related infection by Staphylococcus aureus. After administration of antibiotic and steroid therapy, purpura disappeared and p-ANCA gradually became negative. This case supports the conclusion that infection can be pathogenesis of the vasculitis, including ANCA-positive HSP. Additionally, impregnation of catheters with antibiotics can be an effective treatment for catheter infections.
