[Quinine-induced renal bilateral cortical necrosis]. / Nécrose corticale rénale bilatérale induite par la quinine.

ABSTRACT

Acute bilateral renal cortical necrosis is a rare cause of renal failure frequently induced by disseminated intravascular coagulation (Dic) following obstetrical complications, sepsis and drugs. We describe a case of Dic with bilateral cortical necrosis after ingestion of only one tablet of quinine. A 41-year-old woman was admitted for severe abdominal pain, melaena, fever and anuria two hours after quinine tablet intake for nocturnal leg cramps. Her medical history included angioneurotic edema caused by chloroquine for malaria prevention. Physical examination was normal. Laboratory data showed acute renal failure, hemolytic anemia without schistocytes and Dic. Platelet antibodies were negative. Ultrasonographic examination showed a complete defect of renal perfusion with permeable renal arteries. Results of abdominal CT scan and MAG3 scintigraphy led to the diagnosis of bilateral renal cortical necrosis. The patient underwent plasma exchanges with fresh frozen plasma which induced rapid resolution of Dic. She remained dependent on chronic hemodialysis. Quinine-induced microangiopathic hemolytic anemia and Dic is a rare described entity. These complications occur typically in quinine-sensitized subjects. The presence of acute renal failure is generally associated with poor prognosis in case of bilateral renal cortical necrosis. Caution is required for the prescription of quinine derivates, which should be avoided in patients experienced on adverse reaction to the drug.
