Comparison of the effectiveness of 2 treatment regimens in patients with isoniazid-resistant tuberculosis

We compared the effectiveness of 2 treatment regimens for isoniazid-resistant tuberculosis [TB] in 42 patients attending a TB referral centre in the Islamic Republic of Iran. The patients were divided into 2 treatment groups: 26 received the 6-month standard HRZE treatment and 16 received a modified treatment of RZE for 6 months. There were no significant differences in age or sex of the groups. With the standard method of treatment, 21 [80.8%] patients were cured, 4 [15.4%] resulted in treatment failure, and 1 [3.8%] died. In the modified treatment group, 16 [100%] patients were cured. These differences were not statistically significantly different [P = 0.194]
