Hepatitis during chloroguanide prophylaxis.

This case shows that it is possible to develop drug-induced hepatitis with considerable morbidity while taking chloroguanide prophylaxis.

A patient was admitted with fever and jaundice. This man had recently returned from Indonesia and was still using chloroguanide 200 mg once daily for 6 weeks. Evaluation of the liver function test results was consistent with cholestatic liver disease (alkaline phosphatase 158 U/L, aspartate aminotransferase 33 U/L, alanine aminotransferase 58 U/L increasing up to 183 U/L, gamma-glutamyl transferase 96 U/L). This condition was thought to be caused by chloroguanide. A biopsy of the liver indicated drug-induced hepatitis.

To our knowledge, this is the first report in the literature of cholestatic hepatitis associated with chloroguanide prophylaxis. In our patient, chloroguanide-induced hepatotoxicity can be considered as a combined allergic and idiosyncratic manifestation.

To describe a case of severe hepatitis that we attribute to the use of chloroguanide.
