Characterizing HIV-1 Genetic Subtypes and Drug Resistance Mutations among Children, Adolescents and Pregnant Women in Sierra Leone.

ABSTRACT: Human immunodeficiency virus (HIV) drug resistance (HIVDR) is widespread in sub-Saharan Africa. Children and pregnant women are particularly vulnerable, and laboratory testing capacity remains limited. We, therefore, used a cross-sectional design and convenience sampling to characterize HIV subtypes and resistance-associated mutations (RAMs) in these groups in Sierra Leone. In total, 96 children (age 2-9 years, 100% ART-experienced), 47 adolescents (age 10-18 years, 100% ART-experienced), and 54 pregnant women (>18 years, 72% ART-experienced) were enrolled. Median treatment durations were 36, 84, and 3 months, respectively, while the sequencing success rates were 45%, 70%, and 59%, respectively, among children, adolescents, and pregnant women. Overall, the predominant HIV-1 subtype was CRF02_AG (87.9%, 95/108), with minority variants constituting 12%. Among children and adolescents, the most common RAMs were M184V (76.6%, n = 49/64), K103N (45.3%, n = 29/64), Y181C/V/I (28.1%, n = 18/64), T215F/Y (25.0%, n = 16/64), and V108I (18.8%, n = 12/64). Among pregnant women, the most frequent RAMs were K103N (20.6%, n = 7/34), M184V (11.8%, n = 4/34), Y181C/V/I (5.9%, n = 2/34), P225H (8.8%, n = 3/34), and K219N/E/Q/R (5.9%, n = 2/34). Protease and integrase inhibitor-RAMs were relatively few or absent. Based on the genotype susceptibility score distributions, 73%, 88%, and 14% of children, adolescents, and pregnant women, respectively, were not susceptible to all three drug components of the WHO preferred first-line regimens per 2018 guidelines. These findings suggest that routine HIVDR surveillance and access to better ART choices may improve treatment outcomes in Sierra Leone.

Project description:BackgroundThe quality of contraceptive counseling information received by prospective clients of family planning services can greatly influence both the uptake and continued use of contraceptives. Therefore, an understanding of the level and determinants of quality contraception information among young women in Sierra Leon could inform family programs, with the aim of reducing the high unmet need in the country.MethodsWe analyzed secondary data from the 2019 Sierra Leone Demographic Health Survey (SLDHS). Participants were young women aged 15-24 years, who were using a family planning method (n = 1,506). Good quality family planning counselling was defined a composite variable that included; a woman being told about side effects, how to deal with side effects, and the availability of other family planning methods/options. Logistic regression was performed using SPSS software version 25.ResultsOut of 1,506 young women, 955 (63.4%, 95% CI: 60.5-65.3) received good quality family planning counselling services. Of the 36.6% that received inadequate counselling, 17.1% received no counselling at all. Good quality family planning counselling services was positively associated with receiving family planning services from government health facilities (aOR: 2.50, 95% CI: 1.83-3.41), having no major challenges with distance to access healthcare (aOR: 1.45, 95% CI: 1.10-1.90), having visited a health facility (AOR: 1.93, 95% CI: 1.45-2.58), and having been visited by a health field worker within the last 12 months (aOR: 1.67, 95% CI: 1.24-2.26) while residing in the southern region ( aOR: 0.39, 95% CI: 0.22-0.69) and belonging to the richest wealth quintile (aOR: 0.49, 95% CI: 0.24-0.98) were associated with less odds of receiving good quality family planning counselling services.ConclusionAbout 37% of the young women in Sierra Leone do not receive good quality family planning counselling services of which 17.1% received none. Based on the study's findings, it is important to emphasize the need to ensure that all young women have access to proper counselling services especially for those receiving these services from private health units, from the southern region and richest wealth quintile. Ensuring easier access through increasing affordable and friendly access points and strengthening field health workers' capacity in providing family planning services could also help improve access to good quality family planning services.

Project description:BackgroundA nationwide assessment of the link between women's empowerment and homebirth has not been fully examined in Sierra Leone. Our study examined the association between women's empowerment and homebirth among childbearing women in Sierra Leone using the 2019 Sierra Leone Demographic Health Survey (2019 SLDHS) data.MethodWe used the individual file (IR) of the 2019 SLDHS dataset for our analysis. A total of 7377 women aged 15-49 years who gave birth in the five years preceding the survey were included. Outcome variable was "home birth of their last child among women in the five years preceding the 2019 SLDHS. Women's empowerment parameters include women's knowledge level, economic participation, decision-making ability and power to refuse the idea of intimate partner violence. We used the complex sample command on SPSS version 28 to conduct descriptive and multivariate logistic regression analyses.ResultsThree in every 20 women had home childbirth (n = 1177; 15.3%). Women with low [aOR 2.04; 95% CI 1.43-2.92] and medium [aOR 1.44; 95%CI 1.05-1.97] levels of knowledge had higher odds of giving birth at home compared to those with high levels of knowledge. Women who did not have power to refuse the idea of intimate partner violence against women were more likely to had given birth at home [aOR 1.38; 95% CI1.09-1.74]. In addition, women with no [aOR 2.71; 95% CI1.34-5.46) and less than four antenatal care visits [aOR 2.08; 95% CI:1.51-2.88] and for whom distance to a health facility was a major problem [aOR 1.95; 95% CI1.49-2.56] were more likely to have had a homebirth. However, no statistically significant association was observed between a women's decision-making power and home birth [aOR 1.11; 95% CI 0.86-1.41].ConclusionDespite improvements in maternal health indicators, homebirth by unskilled birth attendants is still a public health concern in Sierra Leone. Women with low knowledge levels, who did not have power to refuse the idea of intimate partner violence against women, had less than four ANC visits and considered distance to a health facility as a major problem had higher odds of giving birth at home. Our findings reflect the need to empower women by improving their knowledge level through girl child and adult education, increasing media exposure, changing societal norms and unequal power relations that promote gender-based violence against women, and improving roads and transport infrastructure.

Project description:BACKGROUND:HBV, HCV, HDV and HIV are blood borne and can be transmitted from mother-to-child. Reports of HBV infection rates show up to 11.9% in Cameroon while for HCV, the rate is less than 2%. More so, as pregnant women get enrolled in the HIV PMTCT Programme and stay in the care continuum, selection of HIV-1 drug resistant strains is evident. We sought to determine the seroprevalence of HBV, HCV, HDV and HIV among pregnant women, assess their knowledge, attitudes and practices on transmission and prevention of HBV infection, and determine HIV drug resistance profile of breastfeeding women. METHODS:A serosurvey of HBV, HCV, HDV and HIV was carried out among 1005 pregnant women in Yaounde, Cameroon. In 40 HIV-infected breastfeeding women enrolled in the PMTCT Programme, HIV-1 genotypes and HIV-1 resistance to NRTIs, NNRTIs and PIs, were determined by phylogeny and the Stanford University HIV Drug Resistance interpretation tool, respectively. RESULTS:Among the pregnant women, the rates of HIV-1, HBV, HCV and HDV infections were 8.5, 6.4, 0.8 and 4.0%, respectively. About 5.9% of the women knew their HBV status before pregnancy unlike 63.7% who knew their HIV status. Although 83.3% reported that vaccination against HBV infection is a method of prevention, and 47.1% knew that HBV could be transmitted from mother-to-child, only 2.5% had received the Hepatitis B vaccine. Of the 40 women on antiretroviral therapy (ART), 9 had at least one major resistance-associated mutation (RAM, 22.5%) to NRTI, NNRTI or PI. Of these M184?V (12.5%), K70R (10.0%), K103?N (12.5%), Y181C (10.0%), M46?L (2.5%) and L90?M (2.5%) were most frequently identified, suggesting resistance to lamivudine, nevirapine, efavirenz and zidovudine. Eighty four percent were infected with HIV-1 recombinant strains with CRF02_AG predominating (50%). CONCLUSIONS:The rates of HBV and HIV-1 infections point to the need for early diagnosis of these viruses during pregnancy and referral to care services in order to minimize the risk of MTCT. Furthermore, our results would be useful for evaluating the HIV PMTCT Programme and Treatment Guidelines for Cameroon.
