Abstract

Chemoprophylaxis with hydroxychloroquine (HCQ) and primaquine has been used in the Republic of Korea (ROK) Army since 1997. It may facilitate the development of chloroquine (CQ)-resistant strains of Plasmodium vivax. We investigated the therapeutic efficacy of HCQ and the pvmdr1 gene polymorphisms in P. vivax. From June to September 2006, 102 soldiers with vivax malaria near the demilitarized zone in Gyeonggi-do, ROK, were enrolled in the study. We determined the status of compliance of chemoprophylaxis. In 85 patients, therapeutic efficacy was monitored 28 days after standard HCQ treatment; 66 (64.7%) of 102 malaria patients had taken all chemoprolaxis with HCQ. In all patients enrolled in the therapeutic efficacy monitoring, parasitemia had not been observed since 3 days after standard HCQ treatment. However, the ubiquitous presence of the F1076L mutation of the pvmdr1 was observed. There was no evidence that the F1076L mutation of pvmdr1 could contribute to failure of HCQ treatment.

摘要

自 1997 年以来,羟氯喹(HCQ)和伯氨喹联合化学预防方案一直在韩国军队中使用。它可能会促进恶性疟原虫对氯喹(CQ)的耐药株的产生。我们调查了 HCQ 治疗效果和恶性疟原虫 pvmdr1 基因多态性。2006 年 6 月至 9 月,102 名在京畿道非军事区附近患有间日疟的士兵参加了这项研究。我们确定了化学预防的用药依从性。在 85 名接受标准 HCQ 治疗的患者中,监测了 28 天的治疗效果;102 例疟疾病例中 66 例(64.7%)患者均按规定服用了 HCQ 预防药物。在所有接受治疗效果监测的患者中,自标准 HCQ 治疗后 3 天起,均未观察到寄生虫血症。然而,普遍存在恶性疟原虫 pvmdr1 的 F1076L 突变。没有证据表明 pvmdr1 的 F1076L 突变会导致 HCQ 治疗失败。
