摘要

Introduction: Mostly reported common side effects of carbimazole are cutaneous allergies and severe agranulocytosis. However, hepatotoxicity is rarely described. Thus, we report four observations of carbimazole drug-induced hepatitis during the treatment of Graves’ disease, which imputability is likely and probably an immuno-allergic mechanism. Observations: They were four women whose average age was 43 years, with extreme ages of 32 and 54. Patients were monitored and treated with carbimazole in doses contained between 40 mg and 60 mg per day. Clinical manifestations of liver injury were mainly dominated by cholestatic jaundice, found in 100% of our patients. A painful sensitivity of the right hypochondrium was concomitant with jaundice for two patients. The jaundice time to onset after the beginning of treatment with carbimazole varies between 1 month and 6 months. They all had acute hepatitis. The biological assays used to determine the type of liver injury showed, in all cases, a mixed, cholestatic and cytolytic hepatitis. Therapeutically, in all patients, carbimazole was stopped as soon as the suspicion of its incrimination in the occurrence of liver damage was set up. They all had a substitution of carbimazole with benzylthiouracil. Evolution was favorable for all patients, after therapeutic substitution. It was marked by disappearance of jaundice and normalization of the liver biological parameters within a maximum delay of two months after stopping carbimazole use. Conclusion: Treatment with synthetic antithyroid drugs, particularly carbimazole that is most widely used in our regions, requires clinical and biological monitoring. This surveillance, which is often difficult in Africa because of the limited economic resources, can lead to the occurrence of side effects such as potentially serious drug-induced hepatitis, but which has been favorable in our observations.
