Lancet:7日伯氨喹疗法治疗间日疟

2019-07-22 MedSci MedSci原创

研究发现,对于葡萄糖-6-磷酸脱氢酶正常的间日疟患者,7天与14天伯氨喹治疗的差异不显著,并且短疗程方案的依从性更高,有望提高伯氨喹治疗的疗效

伯氨喹是唯一被广泛使用的预防间日疟(VAX)原虫疟疾复发的药物,但14天标准治疗的效果不显著。近日研究人员评估了7天伯氨喹短疗程间日疟的疗效。

研究在阿富汗、埃塞俄比亚、印度尼西亚和越南开展。葡萄糖-6-磷酸脱氢酶(G6PD)正常和非复杂的VAX疟患者参与,随机接受7天(1.0mg/kg/天)、14天(0.5mg/kg/天)伯氨喹治疗或安慰剂。研究的主要终点是12个月随访期间症状性P-VAX寄生虫血症的发生率。

2336名患者参与,症状性间日疟在7天组935例患者中的比例为0.18 ,14天组937例患者中组为0.16,差异为0.02。安慰剂组464例患者的发病率为0.96。7天组935例患者中有9例(1.0%)在开始治疗后42天内出现药物相关严重不良事件,14天组937例患者中有1例(0.1%)在开始治疗后42天内出现药物相关严重不良事件,对照组464例患者中无1例发生药物相关严重不良事件。严重不良事件中有4例为严重溶血(其中7天组3例,14天组1例)。

研究发现,对于葡萄糖-6-磷酸脱氢酶正常的间日疟患者,7天与14天伯氨喹治疗的差异不显著,并且短疗程方案的依从性更高,有望提高伯氨喹治疗的疗效。
