[PMID: 38941957 DOI: 10.1016/j.ebiom.2024.105210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 05/07/2024] [Accepted: 06/04/2024] [Indexed: 06/30/2024] Open
Abstract
BACKGROUND In developing countries, the safety of blood transfusions remains an important public health concern as it is associated with a higher risk of transfusion-transmissible infections (TTIs). In this study, we aimed to estimate the seroprevalence of HIV among blood donors in Africa and assess the temporal trends and regional differences within the continent through a systematic review and meta-analysis. METHODS Seven electronic databases (PubMed, Web of Science, Cochrane, Scopus, HINARI, Global Index Medicus and Clinical. TRIAL gov) were searched for relevant studies for our research. We included all primary studies that estimated the seroprevalence of HIV among blood donors in Africa with an age population from 16 to 65 years old, without language restrictions, from inception up to March 1st 2024. The pooled seroprevalence was estimated through the DerSimonian-Laird random effects model. The temporal trends and regional differences were assessed through subgroup and meta-regression analysis. FINDINGS We obtained 122 studies that met our inclusion criteria, comprising 7,814,996 blood donors tested for HIV. Sixty-six percent of the studies were from Western and Eastern Africa. The pooled seroprevalence of HIV among blood donors in Africa was 2.66% (95% CI: 2.17-3.20%; I2 = 99.80%, p < 0.01). The highest prevalence was observed in the Central African region, 3.28% (95% CI: 2.57%-4.06%), followed by the Eastern 3.21% (95% CI: 2.12%-4.52%), and the Western 2.66% (95% CI: 1.93%-3.49%) regions. Lower prevalences were observed in the Northern region, 0.57% (95% CI: 0.0%-2.10%), followed by the Southern African region with 0.45% (95% CI: 0.16%-0.86%). We observed a temporal decreased trend of HIV prevalence. INTERPRETATION The prevalence of HIV infection among African blood donors remains high and is not homogeneous across the continent. Efficient measures to strengthen HIV testing and prevent HIV transmission through blood transfusion are needed in Africa. Systematic review protocol registration: PROSPERO CRD42023395616.

HIV, syphilis and sexual-risk behaviours' prevalence among in-and out-of-school adolescent girls and young women in Zambia: A cross-sectional survey study. PLoS One 2024; 19:e0294545. [PMID: 38837995 DOI: 10.1371/journal.pone.0294545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 05/06/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND In Zambia, 3.8% of young women and men aged 15-24 are HIV positive. However, like in most developing nations, HIV prevalence is higher among young women than young men (5.6% versus 1.8%). Despite the recognition of the rights of young people to sexual reproductive health (SRH) information and services, adolescent and young people (AYP) still face challenges in accessing healthcare in public health institutions including access to comprehensive knowledge on HIV/AIDs, HIV testing and contraceptives. The overall objective of the study was to collect baseline HIV, SRH and gender based violence (GBV) data at district level to inform the design of interventions targeting adolescent girls and young women (AGYW) aged 10-24 years in 20 districts of Zambia. METHODS A cross-sectional, mixed-methods study was conducted in 20 districts of Zambia with the highest incidence of HIV. Data was collected between August and October 2022 with a total response rate of 92% (12,813/13960), constituting 5979 (46.7%) in-school and 6834 (53.3%) out-of-school participants. RESULTS Overall, Mwinilunga, Chinsali, Chisamba and Chembe districts had the highest number of respondents, while Sinazongwe and Mungwi districts contributed the least. The overall age distribution was such that 12.6% (n = 1617) of those interviewed were aged 10 to 14 years, 35.4% (n = 4536) were aged 15-19 years, and 52.0% (n = 6660) were aged 20-24 years. The overall mean age at first sex among AGYW interviewed was 16.6 years which was broken down as follows: 16.2 years for in-school and 16.8 years for out of school. Overall, most of the respondents had first time sex with either their boyfriend (80.4%) or husband (15.6%), with 2.4% of the in-school participants reporting to have had their sexual debut in marriage compared to 21.0% among out-of-school AGYW. Prevalence of HIV was higher in the out-of-school compared to the in-school participants (5.5% vs 2.0%), Similarly, the prevalence of syphilis was higher in the out-of-school than the in-school participants (4.1% vs 1.5%). CONCLUSION The study focused on assessing the prevalence and vulnerability of HIV, syphilis, GBV, and SRH services uptake among adolescent girls and young women, and exploring factors affecting girls' stay-in-school and re-engagement. The study found that HIV and syphilis are still significant public health problems among adolescent girls and young women in Zambia, emphasizing the need for increased efforts to prevent and manage these infections.

Quintas AE, Dias CC, Cogle ADC, Cordeiro L, Sarmento A. Seroprevalence of viral transfusion transmissible infections (HBsAg, anti-HCV, anti-HIV, Syphilis) and coinfection among healthy volunteer blood donors during 5-years in Luanda, Angola. Braz J Infect Dis 2023; 27:103704. [PMID: 38036021 PMCID: PMC10698569 DOI: 10.1016/j.bjid.2023.103704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 11/09/2023] [Accepted: 11/12/2023] [Indexed: 12/02/2023] Open
Abstract
BACKGROUND The transmission of diseases by blood products continues to be a worldwide health problem, especially in Africa. Seroprevalence rates of the Hepatitis B virus (HBV), Hepatitis C virus (HCV), Human Immunodeficiency Virus (HIV), Syphilis, and Coinfection in Angola are poorly documented. This study aims to identify the seroprevalence of markers with positive results for Hepatitis B, C, HIV, Syphilis, and Coinfection in blood donors. MATERIAL AND METHODS A retrospective study was conducted using a database of positive serological markers for these infections and coinfection in 2734 blood donors traced from 2011 to 2016 in Luanda, Angola. The Chi-Square test (χ2) or Fisher's exact test was used to evaluate serological positivity and donors' characteristics. A p-value < 0.05 was considered statistically significant. RESULTS 2734 blood donors aged 18 to 64 (median age 32 ± 9) were screened from 2011 to 2016. 73.9 % of the donors were positive for one Transfusion-Transmitted Infection (TTI), and 5.9 % showed evidence of multiple infections. The overall seroprevalence rate was 50.2 % (1373) for HBV, 20 % (436) for Syphilis, 7 % (191) for HIV, 5.1 % (140) for HCV, and 5.8 % for coinfected donors. 2467 (90 %) were men, and 267 (10 %) were women. We identified 118 (5.8 %) coinfected donors. Of those, 40 (33.9 %) simultaneously presented Hepatitis B virus surface antigen (HBsAg)/Syphilis, 24 (20.3 %) HBsAg/HIV, 22 (18.6 %) HBsAg/HCV, 20 (16.9 %) HIV/Syphilis, 8 (6.8 %) HCV/Syphilis, and 4 (3.4 %) HIV/HCV. CONCLUSION A high transfusion-transmissible infection prevalence was found compared to some countries in Sub-Saharan Africa. Therefore, intensifying the screening for these transfusion-transmitted infections in blood donors is critical to ensure blood safety.

Magnitudes and Correlates of Human Immunodeficiency Virus, Hepatitis B Virus, and Syphilis among Pregnant Mothers Attending Antenatal Care in Addis Ababa, Ethiopia. Infect Dis Obstet Gynecol 2022; 2022:6156613. [PMID: 35221648 PMCID: PMC8865988 DOI: 10.1155/2022/6156613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Accepted: 02/07/2022] [Indexed: 11/24/2022] Open
Abstract
Background Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and syphilis are major sexually transmitted infections (STIs) among the general population in Ethiopia, which in turn result in a wide range of adverse pregnancy outcomes. Hence, it is important to determine the seroprevalence and risk factors of HIV, HBV, and syphilis infection among pregnant mothers attending antenatal care in Addis Ababa, Ethiopia. Method A cross-sectional study was conducted among 286 pregnant women from February 1, 2021, to March 30, 2021, in four selected public hospitals in Addis Ababa. Sociodemographic, risky sociocultural, behavioral, and hospital-related factors were collected using an interview-administered questionnaire. Detection of anti-HIV antibodies, hepatitis B surface antigen (HBsAg), and rapid plasma reagin (RPR) for syphilis was conducted. A binary logistic regression analysis was used to determine predictors of STIs using SPSS version 25. Result A total of 281 pregnant mothers with a mean age of 27.5 (SD 4.6) completed the study. Among the participants, the seroprevalence rates of HIV, HBV, and syphilis were 15 (5.3%), 9 (3.2%), and 5 (1.8%), respectively. Twenty six (9.3%) of the participants tested positive for any one of the STIs, and 3 (1.1%) of the women had HIV and syphilis coinfections. History of multiple sexual partners (AOR 3.42, 95% CI: 1.6-11.63) and STIs (AOR 3.7; 95% CI: 1.70-13.45) were significantly associated with HIV infection. Likewise, history of abortion (AOR 7.65, 95% CI: 1.17-49.74), tattooing (AOR 9.72, 95% CI: 1.41-66.73), and rape (AOR 9.72, 95% CI: 1.41-66.73) were significantly associated with hepatitis B virus infection. Husband history of multiple sexual partners (AOR 20.9, 95% CI: 1.8-241.8) was significantly associated with syphilis infection. The educational level of participants, history of tattooing (AOR 6.24, 95% CI: 1.79-21.7), and history of multiple sexual partners (AOR 5.15, 95% CI: 1.68-15.7) were independent predictors of infection with any one of the STIs. Conclusion There is still a high burden of HIV, HBV, and syphilis among pregnant mothers in Ethiopia. History of multiple sexual partners, abortion, rape, and tattooing was a significant predictor of STIs.

Sexual-risk behaviours and HIV and syphilis prevalence among in- and out-of-school adolescent girls and young women in Uganda: A cross-sectional study. PLoS One 2021; 16:e0257321. [PMID: 34506577 PMCID: PMC8432796 DOI: 10.1371/journal.pone.0257321] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 08/20/2021] [Indexed: 11/24/2022] Open
Abstract
Background Adolescent girls and young women (AGYW) are at increased risk of sexually transmitted infections (STIs). We assessed sexual-risk behaviours and HIV and syphilis prevalence among AGYW in Uganda to inform the design of target-specific risk-reduction interventions. Methods This analysis utilizes data from 8,236 AGYW aged 10–24 years, collected in 20 districts, between July and August 2018. AGYW engaged in sexual-risk behaviour if they: a) reported a history of STIs; or b) had their sexual debut before age 15; or c) engaged in sex with 2+ partners in the past 12 months; or c) did not use or used condoms inconsistently with their most recent partners. We diagnosed HIV using DetermineTMHIV-1/2, Stat-PakTMHIV-1/2 and SD Bioline. We used SD Bioline Syphilis test kits to diagnose syphilis and Treponema Pallidum Hemagglutination Assay for confirmatory syphilis testing. Comparison of proportions was done using Chi-square (χ2) tests. Data were analysed using STATA (version 14.1). Results Of 4,488 AGYW (54.5%) that had ever had sex, 12.9% (n = 581) had their sexual debut before age 15; 19.1% (n = 858) reported a history of STIs. Of those that had ever had sex, 79.6% (n = 3,573) had sex in the 12 months preceding the survey; 75.6% (n = 2,707) with one (1) and 24.2% (n = 866) with 2+ partners. Condom use with the most recent sexual partner was low, with only 20.4% (n = 728) reporting consistent condom use while 79.6% (n = 2,842) reported inconsistent or no condom use. In-school AGYW were significantly less likely to have ever had sex (35.6% vs. 73.6%, P<0.001), to have had sexual debut before age 15 (7.7% vs. 15.5%, P<0.001) or to engage in sex with 2+ partners (5.3% vs. 15.8%, P<0.001). Consistent condom use was significantly higher among in-school than out-of-school AGYW (40.1% vs. 12.7%, P<0.001). Overall, 1.7% (n = 143) had HIV while 1.3% (n = 104) had syphilis. HIV and syphilis prevalence was higher among out-of-school than in-school AGYW (HIV: 2.6% vs. 0.9%; syphilis: 2.1% vs. 0.5%, respectively). Conclusion In-school AGYW engaged in more protective sexual behaviors and had less HIV and syphilis than their out-of-school counterparts. These findings suggest a need for target-specific risk-reduction interventions stratified by schooling status.
