Abstract | BACKGROUND:
Clonorchiasis is of considerable public health importance, particularly in the People's Republic of China (PR China), where most of the 15 million individuals infected with Clonorchis sinensis are currently concentrated. Praziquantel is the drug of choice, but tribendimidine might be an alternative. METHODS: We performed a randomized open-label trial in Guangxi, PR China, to assess the efficacy and safety of 400 mg tribendimidine once, 400 mg tribendimidine daily for 3 days, and 75 mg/kg praziquantel in 1 day divided in 3 doses against parasitological-confirmed C. sinensis infections. Cure and egg reduction rates were determined 3 weeks posttreatment using available case analysis. Clinical symptoms were documented at baseline, and adverse events were recorded and graded 3 and 24 hours after each dose. RESULTS: A total of 74 patients were included in the final analysis. Single-dose tribendimidine achieved a cure rate of 44%, whereas cure rates of 58% and 56% were obtained for tribendimidine administered for 3 days and praziquantel, respectively. High egg reduction rates (97.6%-98.8%) were observed for all treatment regimens. Single-dose tribendimidine was the best-tolerated treatment scheme. Patients treated with praziquantel experienced significantly more adverse events than did tribendimidine recipients (P < .05). CONCLUSIONS:
