title: [ANCA associated glomerulonephritis related to benzylthiouracil].
abstract: BACKGROUND
  Vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA) have been reported in patients suffering from Graves' disease treated with anti-thyroid drugs and especially propylthiouracil (PTU).
  
  
  METHODS
  We report a case of Graves' disease treated with benzylthiouracil (Basdène). This therapy was complicated by acute renal insufficiency due to crescentic glomerulonephritis associated with pANCA. After benzylthiouracil withdrawal and under corticosteroids, renal insufficiency, biological inflammation and pANCA levels decreased.
  
  
  CONCLUSIONS
  Similar vasculitis associated with pANCA secondary to anti-thyroid drugs, especially propylthiouracil, were described. This suggests a causal relation between drug and vasculitis. To our best knowledge, it is the first case of vasculitis secondary to benzylthiouracil.
