We report on a 3-year-old Melanesian girl admitted for acute renal failure following subfulminant hepatitis A virus infection. While the child was slowly recovering from severe cytolytic hepatitis, she presented 8 weeks of protracted fever and major eosinophilia (30,000/microl); thereafter, acute renal failure (serum creatinine 295 micromol/l) occurred. Renal histology displayed diffuse eosinophilic infiltrate, with severe acute tubulointerstitial lesions associated with mild glomerular endocapillary proliferation and eosinophilic infiltrate, suggesting an immunoallergic mechanism. The child had received cefixime and cotrimoxazole 3 weeks prior to hospitalisation for the hepatitis A virus infection. The final diagnosis was of the syndrome drug reaction with eosinophilia and systemic symptoms or DRESS, induced by cefixime or cotrimoxazole and possibly triggered by the hepatitis A virus infection.
