title: [Hepatic toxicity of antitubercular agents. Role of different drugs. 199 cases].
abstract: One hundred and ninety-nine cases of hepatic injury related to antituberculous treatment were analysed in order to assess the role played by each drug and to look for predisposing factors. This is a retrospective study of 169 cases reported in the literature and 30 cases reported to the regional pharmacovigilance centre of Paris Saint-Antoine. The mortality rate was related to the dose of isoniazid: it was 43 percent with a daily dose higher than 300 mg, and 9 percent with a daily dose of 300 mg or less (P < 0.001). Hepatic injury appeared significantly earlier in the case of rifampicin combination: 11 weeks without rifampicin and 2 weeks with rifampicin (P < 0.01). The role of pyrazinamide was difficult to determine because isoniazid and pyrazinamide were always used in combination. The influence of a preexisting liver disease could not be evaluated because of the small number of cases reported (8 cases). Alcoholism did not increase the mortality rate. Our results confirm the dose-dependent toxicity of isoniazid. Because of the short time elapsed before the apparent onset of hepatitis observed with the rifampicin combination, a close supervision of the patients should be exerted during the first weeks of treatment.
