BACKGROUND: To compare the efficacy of two different regimens in treatment of brucellosis. METHODS: This randomised clinical trial study was conducted on 280 patients with brucellosis in Babol, Iran, from April 1999 to January 2002. One of the following two regimens was randomly prescribed for two months: co-trimoxazole plus doxycycline (CD group) and co-trimoxazole plus rifampin (CR group). RESULTS:140 patients with the mean age of 35.56 (16.2) years, and 140 patients with the mean age of 31.39 (18) years, were treated with co-trimoxazole plus doxycycline and co-trimoxazole plus rifampin, respectively. Clinical manifestations and laboratory test results were similar in both groups (p >0.05), except in sex and clinical types (p <0.05). Failure of treatment was seen in 10 (7.1%) and 23 (16.4%) cases treated in the CD group and CR group, respectively (95% CI, 0.174 to 0.862; OR = 0.387; p = 0.020). Relapse was seen in 12 cases (8.6%) treated in the CD group and in 14 cases (10%) treated in the CR group (95% CI, 0.365 to 1.87; OR = 0.826; p = 0.646). Failure of treatment plus relapse was seen in 22 (15.7%) and 37 (26.4%) cases treated in the CD group and CR group, respectively (95%CI, 0.278 to 0.929, OR = 0.508; p = 0.028). Risk for developing of failure of treatment and relapse in patients treated with co-trimoxazole plus rifampin was 1.96 times higher than those treated with co-trimoxazole plus doxycycline. Among the relapsed patients, 18 (69.2%) cases occurred within 6 months after completion of therapy, and most of them in uncomplicated patients. CONCLUSION: Using two months of treatment, the efficacy of co-trimoxazole plus doxycycline is better than co-trimoxazole plus rifampin.
