The Prevention of Mother to Child transmission (PMTCT) of HIV, an important intervention in the fight against HIV/AIDS can only be of benefit if the HIV status of the mother is known. Unfortunately, some women receive HIV counseling and testing (HCT) during the window period or prior to new infection in pregnancy and therefore, miss-out on the gains of PMTCT. A repeat HIV test would identify this later seroconversion and ensure early intervention. This study aimed at determining the prevalence of HIV seroconversion during pregnancy and assessing the factors associated with HIV seroconversion in clients who attended ante-natal clinic (ANC) in University of Uyo Teaching Hospital, Uyo.
A descriptive cross-sectional design was used to study 502 HIV negative clients who consecutively presented for ANC in the University of Uyo Teaching Hospital Uyo over a 3 months period (July -September 2013).
Fifteen (3%) of the 502 women who were HIV negative at booking visit tested positive (seroconverted) to HIV. Determinants of seroconversion at multivariate level were age bracket of 25-29 years (OR: 3.20; 95%CI: 2.39-4.29) clients' partners who had sexually transmitted infections, as evidenced by penile discharge (OR: 0.09; 95%CI: 0.01-0.45); Clients in polygamous setting (OR: 3.98; CI: 1.64-9.65); those taking alcohol (OR: 0.12; CI: 0.20-0.80) and those with partners taking recreational drugs (OR: 0.05, 95%CI: 0.002-0.995).
The study revealed a high seroconversion rate. Re-screening of pregnant women after the booking HCT is a very cost effective and beneficial strategy for the elimination of mother to child transmission of HIV.
预防艾滋病毒母婴传播(PMTCT)是抗击艾滋病毒/艾滋病的一项重要干预措施,只有在知晓母亲的艾滋病毒感染状况时才能发挥作用。不幸的是,一些女性在窗口期或孕期新感染之前接受了艾滋病毒咨询和检测(HCT),因此错过了PMTCT的益处。重复进行艾滋病毒检测可以发现这种后期的血清转化,并确保早期干预。本研究旨在确定孕期艾滋病毒血清转化的患病率,并评估在乌约大学教学医院参加产前检查(ANC)的患者中与艾滋病毒血清转化相关的因素。
采用描述性横断面设计,对2013年7月至9月这3个月期间在乌约大学教学医院连续前来进行产前检查的502名艾滋病毒阴性患者进行研究。
在初次就诊时艾滋病毒呈阴性的502名女性中,有15名(3%)检测出艾滋病毒呈阳性(血清转化)。多变量分析中血清转化的决定因素包括年龄在25至29岁之间(比值比:3.20;95%置信区间:2.39 - 4.29)、伴侣有性传播感染(表现为阴茎分泌物)的患者(比值比:0.09;95%置信区间:0.01 - 0.45);处于一夫多妻制环境中的患者(比值比:3.98;置信区间:1.64 - 9.65);饮酒者(比值比:0.12;置信区间:0.20 - 0.80)以及伴侣使用消遣性药物的患者(比值比:0.05,95%置信区间:0.002 - 0.995)。
该研究显示血清转化率较高。在初次产前检查艾滋病毒检测后对孕妇进行重新筛查是消除艾滋病毒母婴传播的一项非常具有成本效益且有益的策略。
