Plasmodium vivax intervention trials customarily report uncorrected treatment failure rates. Application of recrudescence-reinfection genotyping and drug resistance single-nucleotide polymorphism typing to a 4-arm comparative efficacy trial illustrated that molecular approaches can assist in understanding the relative contributions of true drug resistance (recurrent with same genotype) and new infections to treatment failure. The PCR-corrected adequate clinical and parasitologic response may constitute an informative secondary endpoint in future P. vivax drug trials.
间日疟原虫干预试验通常报告未经校正的治疗失败率。应用复发再感染基因分型和药物耐药性单核苷酸多态性分型对四臂比较疗效试验的研究表明,分子方法有助于了解真正的药物耐药性(与相同基因型复发)和新感染对治疗失败的相对贡献。PCR 校正后的充分临床和寄生虫学反应可能成为未来间日疟原虫药物试验的一个有用的次要终点。
