Cysticercosis is the presence of Taenia solium larvae in humans or swines tissues. It is a public health problem related to bad hygienic habits and consumption of infected pork. T. crassiceps is a widely used cysticercosis experimental model. The combination of two effective drugs such as nitazoxanide (NTZ) and flubendazole (FBZ) may potentialize their effect. The aim of this study was to use biochemical analysis to determine the metabolic impact of the combination of NTZ and FBZ on cysticerci inoculated intraperitoneally in mice.
Balb/c mice intraperitoneally infected with T. crassiceps cysticerci received a single oral dose NTZ/FBZ (50 mg/kg). 24 h after the treatment the cysticerci were removed, frozen and analyzed by high performance liquid chromatography regarding the detection of the following metabolic pathways: glycolysis, gluconeogenesis, homolactic fermentation, tricarboxylic acid cycle, proteins catabolism and fatty acids oxidation.
The treatment with the drugs combination induced a statistically significant increase in gluconeogenesis and in protein catabolism when compared to the control groups.
The drugs combination is potentialized and capable of causing greater metabolic stress than the separate treatment with NTZ or FBZ, showing its potential for an alternative cysticercosis treatment.
囊尾蚴病是猪带绦虫幼虫在人体或猪组织中的存在。它是与不良卫生习惯和食用受感染猪肉有关的公共卫生问题。细粒棘球蚴是一种广泛应用的囊尾蚴病实验模型。硝唑尼特(NTZ)和氟苯达唑(FBZ)这两种有效药物的联合使用可能会增强其效果。本研究的目的是使用生化分析来确定 NTZ 和 FBZ 联合用药对腹腔内接种的小鼠细粒棘球蚴的代谢影响。
用 T. crassiceps 囊尾蚴腹腔感染的 Balb/c 小鼠接受单次口服剂量的 NTZ/FBZ(50mg/kg)。治疗后 24 小时,取出囊尾蚴,冷冻并通过高效液相色谱法分析以下代谢途径:糖酵解、糖异生、同型乳酸发酵、三羧酸循环、蛋白质分解代谢和脂肪酸氧化。
与对照组相比,药物联合治疗诱导了糖异生和蛋白质分解代谢的统计学显著增加。
该药物联合使用具有增效作用,并能引起比单独使用 NTZ 或 FBZ 更大的代谢应激,显示出其作为囊尾蚴病替代治疗的潜力。
