RESUMO
Objective: We systematically identified the prevalence of triplex infections (combined human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV)) in pregnancy. Methods: To gather information on the frequency of triplex infections, we searched the databases of PubMed, CINAHL, and Google Scholar. Without regard to language, we utilized search terms that covered HIV, HBV, HCV, and pregnancy. Pregnant women with triplex infections of HIV, HBV, and HCV were included in studies that also examined the prevalence of triplex infections. Review Manager 5.4.1 was employed to conduct the meta-analysis. Critical appraisal and bias tool risk data were provided as percentages with 95% confidence intervals (95% CIs), and I2 was used as the statistical measure of heterogeneity. The checklist was created by Hoy and colleagues. The study protocol was registered on PROSPERO, under the registration number CRD42020202583. Results: Eight studies involving 5314 women were included. We identified one ongoing study. Pooled prevalence of triplex infections was 0.03% (95% CI: 0.02-0.04%) according to meta-analysis. Subgroup analysis demonstrated a significantly high prevalence of 0.08% (95% CI: 0.06-0.10%; 3863 women) in HIV-positive population than 0.00% (95% CI:-0.00-0.00; 1451 women; P < 0.001) in general obstetric population. Moreover, there was a significant difference in the pooled prevalence between studies published between 2001 and 2010 and between 2011 and 2021 (0.14% (95% CI: 0.12 to 0.16 versus 0.03% (95% CI: 0.02 to 0.04%; P < 0.001))) and participants recruited in the period between 2001 and 2011 and between 2012 and 2021 (0.13% (95% CI: 0.05 to 0.21; p=0.002 versus 0.00% (95% CI: -0.00 to 0.00%; p=1.00))), respectively. Conclusion: The combined prevalence of prenatal triplex infections was 0.03%, with rates notably higher among the group of pregnant women who were HIV-positive and during the recruitment period that took place before 2012. This prevalence still necessitates screening for these infections as necessary.
RESUMO
Objectives: To systematically review literature and identify mother-to-child transmission rates of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus among pregnant women with single, dual, or triplex infections of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in Nigeria. PRISMA guidelines were employed. Searches were on 19 February 2021 in PubMed, Google Scholar and CINAHL on studies published from 1 February 2001 to 31 January 2021 using keywords: "MTCT," "dual infection," "triplex infection," "HIV," "HBV," and "HCV." Studies that reported mother-to-child transmission rate of at least any of human immunodeficiency virus, hepatitis B virus and hepatitis C virus among pregnant women and their infant pairs with single, dual, or triplex infections of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in Nigeria irrespective of publication status or language were eligible. Data were extracted independently by two authors with disagreements resolved by a third author. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary mother-to-child transmission rates in terms of percentage with 95% confidence interval. Protocol was prospectively registered in PROSPERO: CRD42020202070. The search identified 849 reports. After screening titles and abstracts, 25 full-text articles were assessed for eligibility and 18 were included for meta-analysis. We identified one ongoing study. Pooled mother-to-child transmission rates were 2.74% (95% confidence interval: 2.48%-2.99%; 5863 participants; 15 studies) and 55.49% (95% confidence interval: 35.93%-75.04%; 433 participants; three studies), among mother-infant pairs with mono-infection of human immunodeficiency virus and hepatitis B virus, respectively, according to meta-analysis. Overall, the studies showed a moderate risk of bias. The pooled rate of mother-to-child transmission of human immunodeficiency virus was 2.74% and hepatitis B virus was 55.49% among mother-infant pairs with mono-infection of HIV and hepatitis B virus, respectively. No data exists on rates of mother-to-child transmission of hepatitis C virus on mono-infection or mother-to-child transmission of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus among mother-infant pairs with dual or triplex infection of HIV, hepatitis B virus and HCV in Nigeria.
RESUMO
BACKGROUND: Studies reporting factors associated with exclusive breastfeeding are mostly quantitative. No study has performed a systematic qualitative summary to document the recurring constraints and facilitators to exclusive breastfeeding in sub-Saharan African countries from breastfeeding mothers' perspective. This study systematically reviews the literature reporting barriers and facilitators to exclusive breastfeeding from the breastfeeding mothers' perspective in sub-Saharan Africa to develop an educational intervention to optimize exclusive breastfeeding. METHODS: A systematic literature review of qualitative studies such as phenomenological studies, followed by a risk of bias and methodological assessment of the included studies' quality using the Critical Appraisal Skills Programme (CASP) tool was conducted. MEDLINE and Google Scholar were searched from January 1990 to October 2019 to retrieve studies of breastfeeding mothers who had infants aged between 0 and 12 months. Two authors independently carried out the review process and resolved disagreements through consensus. We analyzed the data thematically. RESULTS: After reviewing 92 studies, 20 studies involving 836 participants from 11 countries were eligible. Of the 72 studies excluded, 39 were not conducted in sub-Saharan Africa, and 33 included other participants such as fathers. Three themes emerged as barriers to exclusive breastfeeding (EBF) and five additional themes were identified with facilitators of maternal-infant factors being the most significant in both cases. Maternal employment and knowledge of the benefits of EBF were the most common maternal-infant factors that served as a barrier and a facilitator, respectively. The study's limitations were that the review involved only primary research among breastfeeding mothers living in sub-Saharan Africa and excluded studies not available in the English language. The information synthesized from this review could be used to develop communication strategies employed during individual and group patient education in the hospitals to improve breastfeeding mothers' understanding, acceptance, and practice of exclusive breastfeeding. This review was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42020133761. CONCLUSIONS: This review found that maternal-infant factors have the most significant influence over the practice of exclusive breastfeeding. Therefore, interventions targeted towards maternal-infant factors will improve and optimize exclusive breastfeeding significantly and, ultimately, improve maternal-child health outcomes.
