Hypersensitivity angiitis with granulomatous glomerulitis in a patient with preexisting IgA nephropathy.
Following a 6-year history of asymptomatic proteinuria and microhematuria, a 51-year-old man suffered from acute systemic eruption, liver dysfunction and acute renal failure immediately after developing a cold and taking drugs including piroxicam, aspirin and bristocycline. Renal biopsy revealed progressive IgA nephropathy associated with acute tubulointerstitial nephritis and granulomatous glomerulitis. Although the drug actually responsible for this condition was not defined, it is likely that drug-induced hypersensitivity angiitis with granulomatous glomerulitis was superimposed on preexisting IgA nephropathy in this patient.
