Treatment of Clonorchiasis in Guangxi With Albendazole, Tribendimidine, and Praziquantel

The goal of this clinical trial is to evaluate and compare the efficacy and safety of three commonly used antiparasitic drugs-albendazole, tribendimidine, and praziquantel-for the treatment of clonorchiasis, a liver fluke infection acquired by consuming raw or undercooked freshwater fish. This study aims to answer the following primary questions: How effective is each drug in achieving parasitological cure, as measured by clearance of Clonorchis sinensis eggs in stool? What types and frequencies of adverse events are associated with each treatment? Participants in this randomized, open-label trial will: Be randomly assigned to receive one of the three study drugs according to a predefined dosing regimen. Provide stool samples before treatment and at follow-up to assess for Clonorchis sinensis eggs. Undergo a second round of the same treatment regimen and repeated stool examination if eggs are still detected after the first course. Attend follow-up visits, which include symptom assessment and blood tests (hematology and liver function). Report any side effects, discomfort, or adverse reactions experienced during or after treatment. The findings from this study will help inform optimal therapeutic strategies for clonorchiasis in outpatient clinical settings.
