Many antimalarials sold in sub-Saharan Africa are poor-quality (falsified, substandard, or degraded), and the burden of disease caused by this problem is inadequately quantified. In this article, we estimate the number of under-five deaths caused by ineffective treatment of malaria associated with consumption of poor-quality antimalarials in 39 sub-Saharan countries. Using Latin hypercube sampling our estimates were calculated as the product of the number of private sector antimalarials consumed by malaria-positive children in 2013; the proportion of private sector antimalarials consumed that were of poor-quality; and the case fatality rate (CFR) of under-five malaria-positive children who did not receive appropriate treatment. An estimated 122,350 (interquartile range [IQR]: 91,577-154,736) under-five malaria deaths were associated with consumption of poor-quality antimalarials, representing 3.75% (IQR: 2.81-4.75%) of all under-five deaths in our sample of 39 countries. There is considerable uncertainty surrounding our results because of gaps in data on case fatality rates and prevalence of poor-quality antimalarials. Our analysis highlights the need for further investigation into the distribution of poor-quality antimalarials and the need for stronger surveillance and regulatory efforts to prevent the sale of poor-quality antimalarials.
在撒哈拉以南非洲销售的许多抗疟药物质量不佳(伪造、不合格或变质),而这一问题所导致的疾病负担尚未得到充分量化。在本文中,我们估算了撒哈拉以南39个国家中,因使用质量不佳的抗疟药物进行无效疟疾治疗而导致的五岁以下儿童死亡人数。通过拉丁超立方抽样法,我们的估算值计算如下:2013年疟疾呈阳性的儿童在私营部门消费的抗疟药物数量;私营部门消费的质量不佳的抗疟药物所占比例;以及未接受适当治疗的五岁以下疟疾呈阳性儿童的病死率(CFR)。据估计,122,350例(四分位间距[IQR]:91,577 - 154,736)五岁以下疟疾死亡与使用质量不佳的抗疟药物有关,占我们所研究的39个国家样本中所有五岁以下儿童死亡人数的3.75%(IQR:2.81 - 4.75%)。由于病死率数据以及质量不佳的抗疟药物流行情况方面存在缺口,我们的结果存在相当大的不确定性。我们的分析强调,需要进一步调查质量不佳的抗疟药物的分销情况,以及加强监测和监管力度,以防止销售质量不佳的抗疟药物。
