Genital tract infections among HIV-infected pregnant women in Malawi, Tanzania and Zambia

Abstract

SummaryThe aim of this study was to compare the prevalence and factors associated with genital tract infections among HIV-infected pregnant women from African sites. Participants were recruited from Blantyre and Lilongwe, Malawi; Dar es Salaam, Tanzania; and Lusaka, Zambia. Genital tract infections were assessed at baseline. Of 2627 eligible women enrolled, 2292 were HIV-infected. Of these, 47.8% had bacterial vaginosis (BV), 22.4% had vaginal candidiasis, 18.8% had trichomoniasis, 8.5% had genital warts, 2.6% had chlamydia infection, 2.2% had genital ulcers and 1.7% had gonorrhoea. The main factors associated with genital tract infections included genital warts (adjusted odds ratio [AOR] 1.8, 95% CI 1.2-2.7), genital ulcers (AOR 2.4, 95% CI 1.2-5.1) and abnormal vaginal discharge (AOR 2.5, 95% CI 1.9-3.3) for trichomoniasis. BV was the most common genital tract infection followed by candidiasis and trichomoniasis. Differences in burdens and risk factors call for enhanced interventions for identification of genital tract infections among HIV-infected women.

Prevalence and factors associated with Chlamydia trachomatis infection among women with HIV in São Paulo

“…However, a Canadian study reported a much lower prevalence of CT infection (0.6%) (21) . Our results regarding the prevalence of CT infection are consistent with the results from studies that were performed in Rio de Janeiro (2.2%) (22) , Europe (1%) (23) , and Africa (2.6%) (24) .…”

High burden of STIs among HIV-infected adults prior to initiation of ART in South Africa: a retrospective cohort study

“…A systematic review found only 2 African studies of STIs among people already infected with HIV and one of them was among pregnant women [7,8,9]. Thus the majority of studies examining STI co-infections among people already infected with HIV were in Western Europe and North America, where prevalence, incidence and risk factors for STIs may differ in important ways from that of sub-Saharan Africa.…”

Prevalence of Bacterial Vaginosis and Impact of Genital Hygiene Practices in Non-Pregnant Women in Zanjan, Iran

“…1 In developing countries, patients with genital tract infections often bypass formal healthcare services and seek care in the informal sector. 2 Diverse studies performed, with the objective of establishing the frequency of the most common infectious agents for vaginitis, have shown varying results.…”
