Mzuzu Central Hospital (MZCH), Mzuzu, and Chitipa District Hospital (CDH), Chitipa, Malawi. To compare management and outcomes of human immunodeficiency virus (HIV) exposed infants in early infant diagnosis (EID) programmes at MZCH, where DNA polymerase chain reaction (PCR) testing is performed on site, and CDH, where samples are sent to MZCH, between 2013 and 2014. Retrospective cohort study. Of infants enrolled at MZCH ( = 409) and CDH ( = 176), DNA PCR results were communicated to the children's guardians in respectively 56% and 51% of cases. The median time from sample collection to guardians receiving results was 34 days for MZCH and 56 days for CDH. In both hospitals, only half of the dried blood spot (DBS) samples were collected between 6 and 8 weeks. More guardians from MZCH than CDH received test results within 1 month of sample collection (25% vs. 10%). Among the HIV-positive infants, a higher proportion at MZCH (92%) started antiretroviral therapy than at CDH (46%). The relative risk (RR) of death was higher among infants with late DBS collection (RR 1.3, 95%CI 1.0-1.7) or no collection (RR 5.8, 95%CI 4.6-7.2), and when guardians did not receive test results (RR 8.3, 95%CI 5.7-11.9). EID programmes performed equally poorly at both hospitals, and might be helped by point-of-care DNA PCR testing. Better programme implementation and active follow-up might improve infant outcome and retention in care.
马拉维姆祖祖市的姆祖祖中心医院(MZCH)以及奇蒂帕区的奇蒂帕区医院(CDH)。为比较2013年至2014年期间,在姆祖祖中心医院(现场进行DNA聚合酶链反应(PCR)检测)和奇蒂帕区医院(样本送至姆祖祖中心医院检测)的早期婴儿诊断(EID)项目中,暴露于人类免疫缺陷病毒(HIV)的婴儿的管理情况及结局。回顾性队列研究。在姆祖祖中心医院登记的409名婴儿和奇蒂帕区医院登记的176名婴儿中,分别有56%和51%的病例将DNA PCR检测结果告知了儿童监护人。从样本采集到监护人收到结果的中位时间,姆祖祖中心医院为34天,奇蒂帕区医院为56天。在两家医院,仅一半的干血斑(DBS)样本是在6至8周之间采集的。与奇蒂帕区医院相比,姆祖祖中心医院有更多监护人在样本采集后1个月内收到检测结果(25%对10%)。在HIV阳性婴儿中,姆祖祖中心医院开始抗逆转录病毒治疗的比例(92%)高于奇蒂帕区医院(46%)。干血斑样本采集延迟(相对风险(RR)1.3,95%置信区间(CI)1.0 - 1.7)或未采集(RR 5.8,95%CI 4.6 - 7.2)的婴儿,以及监护人未收到检测结果的婴儿(RR 8.3,95%CI 5.7 - 11.9)死亡的相对风险更高。两家医院的早期婴儿诊断项目表现同样不佳,即时检测DNA PCR可能会有所帮助。更好地实施项目和积极随访可能会改善婴儿结局及护理依从性。
