Аннотация

Background: Praziquantel (PZQ) is the most commonly used anthelmintic drug for treating trematodiases. It was shown here that PZQ in complex with disodium glycyrrhizinate (PZQ-Na2GA, in the 1:10 ratio) has higher bioavailability than PZQ alone. Our aim was to determine the effects of three-time administration of PZQ-Na2GA in an experimental opisthorchiasis felinea model. Methods: The PZQ-Na2GA complex (1:10) at a 400 mg/kg dose (meaning 36.4 mg/kg PZQ) was administered to Opisthorchis felineus-infected hamsters three times under a “9:00 am–6:00 pm–9:00 am” regimen (PZQ-Na2GA × 3). Effects of treatment were assessed as a reduction of helminth load in the hamsters and as changes in physiological, hematological, and blood biochemical parameters. The helminths extracted from the liver of the hamsters that received PZQ-Na2GA thrice were assayed for sensitivity to PZQ in vitro. Results: PZQ-Na2GA × 3 reduced the number of O. felineus helminths in the liver by 87%, which is 30% better than a previously reported effect of one-time administration of the complex. Meanwhile, relative weights of the liver and thymus diminished, and some hematological parameters improved. The helminths extracted from the hamsters 1 month after the PZQ-Na2GA × 3 treatment showed elevated sensitivity to PZQ, as determined in vitro. Conclusion: Compared with previously published data on the effectiveness of various drugs in experimental opisthorchiasis felinea, PZQ-Na2GA × 3 exerts the most potent anthelmintic effect. In addition, PZQ-Na2GA × 3 improves physiological status of O. felineus-infected hamsters and sensitizes the surviving parasites to subsequent PZQ treatment.
