Prevalence of sexually transmitted infections (HIV, hepatitis B virus, herpes simplex virus type 2, and syphilis) in pregnant women in Ethiopia: Trends over 10 years (2005-2014)

Vertical transmission of hepatitis B virus in the WHO African region: a systematic review and meta-analysis

BACKGROUND

More new infections with hepatitis B virus (HBV) occur annually in the WHO African region than in the rest of the world combined. We did a systematic review and meta-analysis to estimate the prevalence of hepatitis B surface antigen (HBsAg) in pregnant women and vertical transmission events in the region.

METHODS

In this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, Africa Index Medicus, and Africa Journals Online for publications between Jan 1, 1992, and Jan 7, 2024, with no language restrictions. HBsAg prevalence and vertical transmission (HBsAg positivity in children aged 6-12 months) were estimated with the use of binomial mixed models with logit links, stratified by infant vaccination status. We estimated HBsAg prevalence for subregions of Africa and for the WHO African region by weighting by estimated livebirths for each subregion. We estimated transmission events using WHO and UNICEF vaccine coverage data and UN population estimates.

FINDINGS

We included 113 studies reporting on HBsAg prevalence from 190 983 pregnant women and 11 studies reporting on vertical transmission. HBsAg prevalence in women receiving antenatal care in the WHO African region (based on 2014-23 data) was 6·2% (95% CI 5·3-7·2). No relationship between risk of bias and HBsAg prevalence was observed. In 2022, an estimated 172 000 vertical transmission events (95% CI 82 000-383 000) occurred (0·4% of livebirths), a fall from a peak of 339 000 (149 000-634 000; 1·2% of all livebirths) in 2001. Increasing birth dose vaccination coverage to the WHO target of 90% could reduce vertical transmission by 43·7% (95% CI 11·6-78·0) to 97 000 events per year (95% CI 58 000-160 000). Adding maternal antiviral prophylaxis with 90% coverage could reduce transmission by 86·3% (95% CI 78·4-94·6) to 24 000 events per year (95% CI 14 000-39 000; 0·06% of livebirths) and achieve WHO elimination targets.

INTERPRETATION

Vertical transmission is an important contributor to HBV transmission in the WHO African region. Scaling up of hepatitis B birth dose vaccination and antiviral prophylaxis is urgently needed, which could achieve elimination of vertical transmission.

Plants used for the management of venereal diseases in sub-Saharan Africa: a systematic review and critical assessment of their research status

BACKGROUND

Sub-Saharan Africa faces one of the highest burdens of venereal diseases (VDs) globally. This review aims to critically evaluate the existing literature on the diverse Indigenous knowledge and medicinal plants utilised for treating VDs in sub-Saharan Africa.

METHODS

We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) protocol to guide the execution of the review. Relevant papers from scientific databases and search engines were assessed. The inclusion criteria included literature published from 2008 and May 16, 2024, and assessment of specific predetermined VDs. Medicinal plants based on certain ethnobotanical indices and data were recorded from each literature.

RESULTS

Among the 131 studies included in this review, a total of 20 relevant ethnobotanical reports were identified, with Nigeria and South Africa having the highest contributions (25% each). A high diversity and richness of 445 ethnobotanically valued anti-venereal plants (99 families) from over 872 Indigenous knowledge holders were inventoried. Plants with the highest diversity of use in traditional treatment of VDs are Cassia abbreviata, Ziziphus mucronata, Ximenia caffra, Catharanthus roseus, and Terminalia prunioides. The most represented families are Fabaceae (15.8%), Cucurbitaceae (5.9%), Solanaceae (5.9%), Euphorbiaceae (5%), and Combretaceae (5%). Roots and leaves were highly utilised with frequencies of 41.5% and 26.3%, respectively. The most used method of preparation are decoctions (36.7%) and infusions (12.2%), whereas oral route (72.9%) dominated the mode of administration of the medicinal plants.

CONCLUSIONS

This review consolidated data from sub-Saharan Africa-notwithstanding a limited number of studies in quantitative synthesis-and identified a diverse array of ethnobotanically valued anti-venereal plants, enabling meaningful conclusions to be drawn for future ethnopharmacological assessments. Effective plant conservation and advancement of ethnobotanical research in the region require stringent regulations and cross-country collaborations.

High Prevalence of Syphilis among Young Pregnant Women in the Brazilian Amazon: A Cross-Sectional Study Based on Clinical Records in a Public Health Reference Unit in the City of Belém

BACKGROUND

Syphilis remains a significant global public health concern, and one of its consequences in pregnant women is the potential occurrence of congenital syphilis due to Treponema pallidum infection. This study determined the prevalence of syphilis among pregnant women undergoing prenatal care in a neighborhood on the outskirts of the city of Belém, Brazilian Amazon.

METHODS

This cross-sectional study used data from clinical records of 611 pregnant women who underwent prenatal care at a public health unit in 2019 and 2020. The reagent result for VDRL was used as an indicator of syphilis. Odds Ratio and chi-square tests were used to evaluate the association of information from pregnant women with syphilis.

RESULTS

The overall prevalence of syphilis was 5.2 % (32/611; 95 % CI: 3.5-7.0 %). Age under 23 years was identified as a risk factor for syphilis.

CONCLUSIONS

The prevalence of syphilis among pregnant women in the outskirts of Belém is high, especially among younger women. There is an urgent need to intensify innovative sexual and reproductive health education initiatives and emphasize the importance of consistent practice of preventive measures against syphilis and other STIs in the Amazon region, especially in the young population.

Seroprevalence of HIV, HBV, and syphilis co-infections and associated factors among pregnant women attending antenatal care in Amhara regional state, northern Ethiopia: A hospital-based cross-sectional study

BACKGROUND

Co-infections involving human immunodeficiency virus (HIV), hepatitis B virus (HBV), and syphilis pose significant public health problems during pregnancy. It can increase the risk of adverse outcomes for both the woman and the infant more than each infection alone does. However, the magnitude of these co-infections remains insufficiently documented. Hence, this study aimed to determine the seroprevalence of HIV, HBV, and syphilis co-infections and associated risk factors among pregnant women attending antenatal care in Amhara region referral hospitals in northern Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted in Amhara regional state referral hospitals from January 1 to February 30, 2024, among 606 pregnant women. Pregnant women were selected using a systematic random sampling technique. An interviewer-administered questionnaire and chart review were used to collect data. Data were analyzed in SPSSV26.0. Descriptive statistics were used to determine the magnitude of co-infections, and binary logistic regression was used to determine associated factors. Variables with a P-value < 0.05 were used to declare statistical significance.

RESULT

Overall, 4.1% (95% CI: 2.7, 6.1) of pregnant women were co-infected. The prevalence of specific co-infections was 2% (95% CI: 1, 3.5) for HIV/HBV, 1.3% (95% CI: 0.6, 2.6) for HIV/syphilis, and 0.8% (95% CI: 0.3, 1.9) for HBV/syphilis. No cases of triple co-infection were observed. Women with a history of unsafe sex (AOR = 8.2, 95% CI: 1.5, 16.7) and incarceration (AOR = 9.3, 95% CI: 1.6, 20.8) were associated with HIV/syphilis co-infection. For HIV/HBV co-infection, contact with jaundice patients (AOR = 5.5, 95% CI: 1.3, 22.5) and women with a history of STIs (AOR = 4.6, 95% CI: 1.4, 14.9) was significantly associated. Women with STI history (AOR = 6.3, 95% CI: 1.2, 15.9) were also significantly associated with HBV/syphilis co-infection.

CONCLUSION

Despite the government's elimination efforts, a relatively high prevalence of coinfections with the infections studied was found among pregnant women. Therefore, HIV, HBV, and syphilis testing and treatment packages should be strengthened by targeting pregnant women with a history of STIs, contact with patients with jaundice, a history of incarceration, and unsafe sex.

Prevalence of sexually transmitted infections, and its associated factors among students in Ethiopia: a systematic review and meta-analysis study

BACKGROUND

Sexually transmitted infections (STIs) are illnesses mainly spread through unprotected sexual activity. There is a scarcity of aggregate evidence in Ethiopia. The aim of this review was to assess the pooled prevalence of STI, and its associated factors among students in Ethiopia to fill the aforementioned gap.

METHODS

We extensively searched the bibliographic databases of PubMed, Scopus, and Google Scholar to obtain eligible studies. Further screening for a reference list of articles was also done. The Microsoft Excel Spreadsheet was used to extract data, and Stata 17 was used for analysis. The PRISMA-guidline and Newcastle-Ottawa quality assessment scale were used for quality appraisal. To check heterogeneity, the Higgs I2 and Cochran's Q tests were employed. Sensitivity and subgroup analysis were implemented. To detect publication bias, Egger's test and funnel plots were used.

RESULTS

The pooled prevalence of STI among students in Ethiopia was 13.6% with a 95% CI (10.2, 17). Findings from sub group analysis based on student category shows that the pooled prevalence of STI were 14.5% among University students, 14.2% among college students and 10.6% among high school students. Having multiple sexual partners (AOR 3.31; 95% CI: 2.40-4.57), not using condoms during sexual intercourse (AOR 2.56; 95% CI: 1.72-3.81), and having poor knowledge about sexually transmitted infections were 3.08 times (AOR 3.08; 95% CI: 1.84-5.15) significantly associated with STI.

CONCLUSION

The pooled prevalence of STIs among students in Ethiopia was high, and factors like having multiple sexual partners, not using condoms during sexual intercourse, and having poor knowledge about sexually transmitted infections were significantly associated with STIs. Hence, reduce STIs among students, strengthening sexual and reproductive health services, raising awareness about transmission and prevention, and promoting consistent condom use through health information dissemination is crucial. Further qualitative studies are suggested to explore the barriers and facilitators of STI prevention.

Triple sexually transmitted infections among pregnant woman in the context of Elimination of mother to child transmission in Southern Ethiopia: Reports from a survey of questionnaires and laboratory studies

Introduction

Sexually transmitted infections (STIs) cause a wide range of public health problems if left untreated. They can lead to adverse birth outcomes, including stillbirth, fetal loss, neonatal death, preterm birth, and low birth weight. Although great efforts have been made to reduce STIs nationally, their incidence remains high in Ethiopia, and their co-infection calls for urgent action. Therefore, this study aimed to identify the determinants of three STIs among pregnant women attending antenatal care (ANC) in the context of the elimination of mother-to-child transmission in public health facilities in Sawla Town, Gofa zone, Southern Ethiopia.

Methods

A cross-sectional study design was conducted among pregnant women attending antenatal care in public health facilities in Sawla Town, Southern Ethiopia, from May to July 2022. Data were collected from pregnant women's serum using an HIV rapid test, an HBsAg rapid test device, and a VDRL for HIV, HBV, and syphilis, respectively. Descriptive statistics, such as frequencies and percentages, were used to describe each relevant variable. Logistic regression analyses were used to identify the determinants of STIs.

Results

A total of 484 pregnant women attending antenatal care were screened. The mean age of the women was 24.0 ± 4.6 years, and nearly half of the participants had completed secondary school or higher. The overall seroprevalence of three STIs (HIV, HBV, and syphilis) among pregnant women was 6.8%. These three sexually transmitted infections were shown to be more common among pregnant women who were not able to read and write, had tattoos, had previously had an abortion, and had a history of multiple sexual partners.

Conclusions

The seroprevalence found in this study was intermediate in comparison with the WHO standard. Efforts should be made to strengthen the existing health education and RH service integration on STI screening, and treatment that further eliminates vertical infection.

Prevalence of and risk factors for Human Immunodeficiency Virus (HIV) infection in entrants and residents of an Ethiopian prison

BACKGROUND

Prisoners generally have a higher prevalence of HIV infection compared to the general population from which they come. Whether this higher prevalence reflects a higher HIV prevalence in those entering prisons or intramural transmission of HIV within prisons or both is unclear. Any of these possibilities would increase the prevalence found in resident prisoners above that in the general population. Moreover, comparisons of HIV prevalence in entrants and residents and in men and women in African prisons are not well documented. The purpose of this study was to estimate and compare the prevalence and risk factors for HIV infection amongst both male as well as female and entrant and resident prisoners in a large Ethiopian Federal Prison.

METHODS

We studied consenting prisoners cross-sectionally from August 2014 through November 2016. Prison entrants were screened continuously for HIV infection and its associated risk factors and residents were screened in two waves one year apart. HIV was diagnosed at the prison hospital laboratory based on the Ethiopian national HIV rapid antibody testing protocol. An external, internationally-accredited reference laboratory confirmed results. Agreement of results between the laboratories were assessed.

RESULTS

A total of 10,778 participants were screened for HIV. Most participants were young (median age of 26 years, IQR: 21-33), male (84%), single (61%), literate (89%), and urban residents (91%) without prior incarceration (96%). Prevalence of HIV was 3.4% overall. Rates of HIV (p = 0.80) were similar in residents and entrants in wave 1 and in entrants in both waves, but were 1.9-fold higher (5.4% vs 2.8%) in residents than entrants in wave 2 (both p<0.001). At entrance to the prison women were more likely to be HIV+ than men (5.5% in women vs 2.5% in men, p< 0.001). In contrast resident women were less likely to be HIV+, but this difference was not statistically significant (3.2% in women vs 4.3% in men, p = 0.125). Other risk factors associated with HIV infection were increasing age (p<0.001), female gender (p<0.001), marital status (never vs other categories, p = 0.016), smaller number of rooms in their houses pre-imprisonment (p = 0.031), TB diagnosis ever (p<0.001), number of lifetime sex partners (especially having 2-10, p<0.001), and genital ulcer (p = 0.037).

CONCLUSIONS

Prevalence of HIV in the residents at this large, central Ethiopian prison was higher than that estimated for the general population and lower than in many other studies from other smaller Ethiopian prisons. A higher prevalence in residents than in entrants were found only in our second wave of screening after one year of continuous screening and treatment, possibly representing increased willingness of residents at increased risk of HIV to participate in the second wave. Thus, this findings did not clearly support intramural transmission of HIV or the effectiveness of screening to reduce prevalence. Finally, the higher HIV prevalence in women than men requires that they be similarly screened and treated for HIV infection.

Burden of HIV, HBV and syphilis among children in urban Ethiopia: Community-based cross-sectional study

BACKGROUND

Children have largely been ignored in the fight against sexually transmitted infection (STI). Among children, STI is reported to be a globally emerging public health challenge. We evaluated the burden of HIV, hepatitis B virus (HBV) and syphilis among children (< 15 years old) and its determinants in urban Ethiopia.

METHODS

For this study, we used data from the Ethiopian Population-based HIV Impact Assessment (EPHIA), collected through a nationally representative, community-based study conducted in Ethiopia from October 2017 to April 2018. We used plasma samples from 4729 children. Moreover, we linked the data and analysed them alongside their respective mothers. Child and maternal HIV status was determined using the national testing algorithm. Plasma samples from children were also tested for syphilis and HBV surface antigen. A descriptive analysis was done followed by bivariable analysis with 95% confidence interval (CI) at a significance level of p < 0.05. We finally evaluated predictors of STIs using regression analysis.

RESULTS

HIV, HBV and syphilis prevalence rates among urban children in Ethiopia were 0.36%, 1.48% and 0.28%, respectively. Children living in Gambella and Addis Ababa had a 6.41-fold (95% CI: 3.20-9.88) and 4.20-fold (95% CI: 3.24-5.46) higher risk of HIV infection compared with those in Dire Dawa. Children of HIV-positive mothers had a 10.31-fold (95% CI: 3.20-18.19) higher risk of HIV infection, and if those mothers were not taking highly active antiretroviral therapy (HAART), the risk was 7.27 times higher (95% CI: 2.57-12.64). Those who were from HIV-positive mothers with viral load ≥ 1000 copies/mL had a 18.64-fold (95% CI: 6.36-31.24) higher risk of HIV infection and those with a history of breastfeeding had a 3.27-fold (95% CI: 1.11-5.67) higher risk. Children from Addis Ababa had a 3.26-fold (95% CI: 1.64-6.66) higher risk of HBV infection compared with those from Dire Dawa. Moreover, for those from HIV-positive mothers and whose mother was not taking HAART, the risk of HBV transmission was 6.37 (95% CI: 2.20-19.96) and 3.62 (95% CI: 1.27-11.29), respectively. Children living in Gambella, Somali, Afar and Tigray had a 7.21-fold (95% CI: 2.30-18.68), 3.10-fold (95% CI: 1.28-3.74) and 1.32-fold (95% CI: 1.11-3.38) higher risk of acquiring active syphilis compared with those living in Dire Dawa, respectively. Those from HIV-positive mothers also had a 4.22-fold (95% CI: 1.16-8.39) higher risk of acquiring active syphilis.

CONCLUSION

The burden of HIV, HBV and syphilis was high among children in urban Ethiopia. The key determinants for the high burden of HIV, syphilis and HBV were maternal factors including maternal HIV status and breastfeeding. This might be due to the challenges associated with mother-to-child transmission. Hence, the programme shall focus on the elimination of the triple infections of HIV, syphilis and HBV.

Burden of hepatitis B virus and syphilis co-infections and its impact on HIV treatment outcome in Ethiopia: nationwide community-based study

BACKGROUND

Hepatitis B virus (HBV) and syphilis have been the most common co-infections that hinder treatment outcomes and increase early mortality among people living with human immunodeficiency virus (PLHIV). In this study, we aimed to determine the burden of HBV and syphilis co-infections and its impact on treatment outcomes among PLHIV in Ethiopia.

METHODS

We used data from the Ethiopian Population-based HIV Impact Assessment (EPHIA), which was a household-based national survey in 2017/2018. Human immunodeficiency virus (HIV) testing was done among 19,136 participants using the national testing algorithm and 662 participants (3.50%) were HIV positives who were further tested for viral hepatitis and syphilis co-infections using HBV surface antigen and Chembio DPP syphilis assay, respectively. Viral load, CD4 count and high-sensitivity C-reactive protein (hsCRP) were done to measure HIV treatment outcomes. Descriptive statistics were used to determine the burden of co-infections and a logistic regression model to evaluate the determinants of co-infections using STATA V17.0.

RESULTS

Overall prevalence of HBV and syphilis co-infection was 5.5% and 2.2%, respectively. HBV and syphilis (double co-infection) was 5.9%. The highest prevalence of HBV co-infection was observed among 10-19 years age group (12.9%) and male participants (7.44%) while the highest syphilis co-infection was among people aged ≥50 years (3.5%) followed by age groups 40-49 (3.3%) and 10-19 years (3.2%). Syphilis co-infection was higher among males (5.2%) compared to females (1.1%). After adjusted regression analysis, HBV co-infected PLHIV had higher odds of virologic failure (AOR (95% confidence interval (CI)) = 6.3 (4.2-14.3)), immunosuppression (CD4 count < 500 cells/mm³) (AOR (95%CI) = 2.1(1.3-4.9)) and inflammation (hsCRP >10 mg/dL) (AOR (95%CI) = 9.2(4.3-14.6)). Immunosuppression was also significantly higher among syphilis co-infected PLHIV (AOR (95%CI) = 3.4 (1.3-5.2)).

CONCLUSIONS

Burden of HBV and syphilis co-infections is high particularly among male and adolescent PLHIV and these co-infections hinder virologic and immunologic outcome in Ethiopia. Hence, the program shall enhance HBV and syphilis testing and treatment.

Burden of sexually transmitted infections from acute HIV infection among women in South Africa: Evidence from a prospective cohort study

PURPOSE

HIV and other sexually transmitted infections (STIs) often co-occur. However, less evidence exists on the long-term STI dynamics among persons living with HIV in sub-Saharan Africa to inform interventions. We investigated the incidence, prevalence and factors associated with STIs, starting from acute HIV infection in a cohort of South African women.

METHODS

The CAPRISA002 study enrolled women with acute HIV infection and performed STI testing and treatment 1-2 times annually from 2004-2020. We estimated STI incidence, re-infection, and prevalence trends before and after antiretroviral treatment (ART). We fitted Cox regression models to identify factors associated with STIs.

RESULTS

We followed up 235 women (median age = 25 years, IQR 22-29) for 7.5 years (IQR 5.7-10.8). New STI and re-infection cases per 100 person-years (PYs) were 5.1 and 9.5 for Neisseria gonorrhoeae (NG), 7.4 and 14.7 for Chlamydia trachomatis (CT), 8.0 and 26.6 for Trichomonas vaginalis (TV), 7.7 and 16.7 for Mycoplasma genitalium (MG) and 25.2 and 37.3 for any STI. STI incidence, was associated with HIV log₁₀ viral load (AHR = 1.24, 95% CI 1.06-1.44), active syphilis (AHR = 16.55, 95% CI 7.49-36.55), a positive HSV-2 PCR (AHR = 1.54, 95% CI 1.01-2.35), bacterial vaginosis (AHR = 1.48, 95% CI 1.01-2.18), recent regular sexual partners at enrolment (one vs none: AHR = 2.62, 95% CI 1.41-4.87; two plus vs none: AHR = 3.68, 95% CI 1.79-7.59) and age (5-year fold: AHR = 0.80, 95% CI 0.70-0.92).

CONCLUSION

The persistent STI/HIV co-infection burden among South African women highlights that early HIV diagnosis and ART initiation needs to be combined with better STI care for women and their partners to prevent HIV and STI transmission.

Seroprevalence of syphilis and its predictors among pregnant women in Buno Bedele zone, southwest Ethiopia: a community-based cross-sectional study

OBJECTIVES

The study was aimed at assessing the prevalence of syphilis and associated factors among pregnant women with antenatal care follow-up.

DESIGN

A health facility-based, cross-sectional study.

SETTING

The study was conducted in 12 health facilities in Buno Bedele zone, southwest Ethiopia.

PARTICIPANTS

Randomly selected 920 pregnant women who came to health facilities in the Buno Bedele zone for antenatal care services from May to August 2021 were included in the study. Women with previously diagnosed syphilis and those on treatment were excluded from the study.

OUTCOME MEASURES

Blood samples and data on sociodemographic and other risk factors for syphilis were collected. Sera were screened for syphilis using the one-step rapid syphilis diagnostic test kit, and positive tests were retested using the rapid plasma reagin test. Data were analysed using SPSS V.22. Bivariate and multivariate logistic regression analyses were used to identify risk factors for maternal syphilis at a p value less than 0.05.

RESULTS

The prevalence of syphilis among pregnant women was found to be 1.4% (95% CI: 0.8% to 2.3%, p=0.002). Women with no formal education (adjusted OR (AOR)=3.6; 95% CI: 1.02 to 13.2, p=0.047), husbands with a history of substance use (AOR=3.3, 95% CI: 1.04 to 10.7, p=0.042), more than one antenatal care visit (AOR=3.5, 95% CI: 1.07 to 10.5, p=0.038), age at marriage under 18 years (AOR=4.3, 95% CI: 2.2 to 7.9, p=0.045) and a woman's poor knowledge of syphilis (AOR=3.3, 95% CI: 1.04 to 10.4, p=0.042) were significantly associated with syphilis.

CONCLUSION

The prevalence of maternal syphilis in this study area was found to be comparable with the national prevalence. Women's educational status, husbands' history of substance use, antenatal care, age at marriage and knowledge about syphilis were the independent predictors of syphilis. Emphasis shall be given to screening all pregnant women, education of women, lifestyle factors and avoiding early marriage.

Investigating latent syphilis in HIV treatment-experienced Ethiopians and response to therapy

Objectives

We investigated people with HIV (PWH) receiving combination antiretroviral therapy (cART) for latent syphilis infection prevalence, risk factors, treatment response, and neurosyphilis.

Methods

A prospective follow-up study was conducted on PWH and latent syphilis. The cases were randomly assigned to receive either benzathine penicillin G (BPG) or doxycycline (DOXY), and the posttreatment response was evaluated after 12 and 24 months. The traditional algorithm was used for serodiagnosis, and a semi-quantitative rapid plasma reagin (RPR) test monitored disease activity and treatment effectiveness.

Results

Of the 823 participants, 64.8% were women, and the mean age was 41.7±10 years. Thirty-one (3.8%) of the participants (22 males and nine females) had latent syphilis. The risk factors were male sex (aOR = 3.14), increasing age (aOR = 1.04 per year), and cART duration (aOR = 1.01 per month). Baseline RPR titers were: ≤1:4 in 19 (61.3%), between 1:8 and 1:32 in 10 (32.2%), and >1:32 in 2 (6.4%). None of the seven cerebrospinal fluid analyses supported a neurosyphilis diagnosis. In the 12^th month of treatment, 27 (87.1%) had adequate serological responses, three (9.7%) had serological nonresponse, and one (3.2%) had treatment failure. Syphilis treatment was repeated in the last four cases with the alternative drug. In terms of adequate serologic response, both therapies were comparable at the 12^th month, p = 0.37. All cases responded to treatment in the 24^th month.

Conclusion

In PWH receiving cART, latent syphilis occurred more in men than women, suggesting an investigation of sexual practices and the impact of antenatal syphilis screening. Syphilis disease activity reduces in the latent stage. Therefore, the routine cerebrospinal fluid analysis contributes little to the diagnosis of asymptomatic neurosyphilis and the treatment success of latent syphilis. DOXY is an alternative to BPG, and cART improves serologic response to latent syphilis treatment.

Prevalence trends and risk factors associated with HIV, syphilis, and hepatitis C virus among pregnant women in Southwest China, 2009–2018

Objective

This study investigated prevalence trends and identified the associated factors of HIV, syphilis and hepatitis C virus (HCV) among pregnant women in the Guangxi Zhuang Autonomous Region (Guangxi), Southwest China.

Methods

Serial cross-sectional surveys were performed annually among pregnant women in Guangxi from 2009 to 2018. Blood specimens were collected to test the prevalence of HIV, syphilis and HCV. Cochran–Armitage analysis was used to assess the trends of HIV, syphilis and HCV prevalence, as well as the sociodemographic and behavioural data. In this study, we used zero-inflated negative binomial (ZINB) regression models to identify factors associated with HIV, syphilis and HCV infection.

Results

A total of 23,879 pregnant women were included in the study. The prevalence of HIV, syphilis and HCV was 0.24%, 0.85% and 0.19%, respectively. There was a decrease in HIV prevalence from 0.54% to 0.10%, a decrease in HCV prevalence from 0.40% to 0.05% and a decrease in syphilis prevalence from 1.53% to 0.30%. The findings based on the ZINB model revealed that pregnant women who had a history of STI had significantly increased risks of HIV (OR 6.63; 95% CI 1.33–32.90) and syphilis (OR 9.06; 95% CI 3.85–21.30) infection, while pregnant women who were unmarried/widowed/divorced were more likely to have HIV (OR 2.81; 95% CI 1.20–6.54) and HCV (OR 58.12; 95% CI, 3.14–1076.99) infection. Furthermore, pregnant women whose husband had a history of STI (OR 5.62; 95% CI 1.24–25.38) or drug use (OR 7.36; 95% CI 1.25–43.43) showed an increased risk of HIV infection.

Conclusions

There was a relatively low prevalence of HIV, syphilis and HCV among pregnant women. Although decreasing trends in HIV, syphilis and HCV infections were observed, effort is needed to promote STI testing in both premarital medical check-ups and antenatal care, especially targeting couples with a history of STI or drug use.

Risky Sexual Practice and Associated Factors Among Youth Preparatory Students in Gondar City, Northwest Ethiopia

Background

Risky sexual practices can negatively affect the health of youths by predisposing them to a variety of sexually transmitted infections, including HIV/AIDS and unwanted pregnancy, which, in turn, would lead to serious lifelong deleterious health, social, and economic consequences. While youths tend to be less well-informed and require more information, little has been known in Ethiopia. Therefore, this study aimed to assess the prevalence of risky sexual practices and associated factors among youth students in Gondar city, northwest Ethiopia.

Methods

A cross-sectional study was conducted among 414 regularly attending youth students in Gondar city from April to May 2019. A simple random sampling technique was used to select the study participants. Data were collected by using a pre-tested, structured, and self-administered questionnaire. Bivariable and multivariable logistic regression analyses were employed, and a multivariable binary logistic regression model was used to identify the effect of independent variables on the outcome variable at p < 0.05 with its 95%CI.

Result

The prevalence of risky sexual practices was 49.3%. Peer pressure (AOR = 1.99, 95%CI: 1.21, 3.26), drinking alcohol (AOR = 4.88 95%CI: 3.06, 7.79), and watching pornography (AOR = 2.82, 95%CI: 1.74, 4.56) were positively associated with the risky sexual practice of youths. Whereas, age, gender, and pocket money did not have any association with risky sexual practice in this study.

Conclusion

In this study, the prevalence of risky sexual practices was found to be high. Thus, multisector collaboration efforts are needed from parents, schools, health facilities, and the government to tackle the exposure of in-school youth toward peer pressure, drinking alcohol, and watching pornographic films, which in turn helps to bring about healthy sexual practices among them.

Prevalence of HIV and hepatitis B virus among pregnant women in Luanda (Angola): geospatial distribution and its association with socio-demographic and clinical-obstetric determinants

Background

HIV and HBV infections remain responsible for high rate of morbidity and mortality in many African Countries, affecting women and newborns. This study aims to analyze the spatial pattern of HIV and HBV infections in pregnant women in Luanda, Angola, and the statistical association between HIV and HBV and socio-economic characteristics, hygiene, and health status.

Methods

Detection of anti-HIV antibodies (total anti-HIV-1, anti-HIV-2 and HIV-1 p24 antigen) and Hepatitis B antigens (HBsAg, HBeAg) and antibodies (anti-HBc Total II, HBc IgM, Anti-HBsT II) was performed by Enzyme Linked Fluorescent Assay (ELFA) in serum samples of 878 pregnant women attended at the Lucrecia Paim Maternity Hospital (LPMH). Data were collected by questionnaire after written consent, and spatial distribution was assessed through a Kernel Density Function. The potential risk factors associated with HIV HBV infection were evaluated using bivariate and multivariate binomial logistic regression analysis.

Results

Anti-HIV antibodies were positive in 118 samples (13.4%) and HBV infection were positive in 226 (25.7%). The seroprevalence of HIV/HBV coinfection was of 6.3%. The results showed that the seroprevalence of HBV was similar in most municipalities: 25.8% in Belas; 26.6% in Viana; 27.6% in Luanda; 19.2% in Cacuaco; and 15.6% Cazenga. For HIV, the seroprevalence was also close ranges among the municipalities: 10.0% in Belas; 14.5% in Viana 14.9% in Luanda and 12.5% in Cazenga. However, the seroprevalence in municipality of in Cacuaco was lower (5.8%) and bivariate and multivariate analysis showed a lower risk for HIV in this area (OR 0.348, CI 0.083–0.986; OR 0.359, CI 0.085–1.021). The multivariate analysis had also showed a significant increased risk for HIV in women with 2 or 3 births (OR 1.860, CI 1.054–3.372).

Conclusions

Our results underlined the need to improve the screening and clinical follow-up of HIV and HBV in Angola, as well the educational campaigns to prevent not only the morbidity and mortality associated with these diseases, but also their transmission, mainly in women in reproductive age and pregnant, encouraging the pre-natal consultations in order to avoid mother-to-child transmission.

Antenatal hepatitis B screening in Nigeria: A comparative analysis with syphilis and HIV

Nigeria has adopted routine screening of pregnant women for hepatitis B virus (HBV) as part of the interventions to eliminate its vertical transmission. However, there is a dearth of evidence on the coverage of routine antenatal HBV screening as recommended in the national guidelines. This study examined the antenatal HBV screening rate and the positivity rate compared with syphilis and HIV. We conducted a descriptive analysis of the 2019 national HIV/AIDS health sector data. The study included approximately 2.8 million pregnant women who received antenatal care (ANC) in over 6000 health facilities providing prevention of mother-to-child transmission of HIV services in Nigeria. Of the ANC clients, 0.2 million (7.2%) were screened for HBV. At the zonal level, the South West had the highest HBV screening rate (19%), while the lowest rate was in the North East (2.5%). The percentage of pregnant women screened for HBV was lower than those screened for syphilis (16.3%) and HIV (90.3%). Among those screened for HBV, the positivity rate was 5%. The HBV positivity rate ranged from 8.5% in the North Central zone to 1.3% in the South East zone. The positivity rates for syphilis and HIV were 0.4% and 0.5%, respectively. Our results indicate a low antenatal HBV screening rate and a wide disparity compared with HIV and syphilis. This finding highlights the need to understand and address the barriers affecting routine antenatal HBV screening and to strengthen the integration of HBV services into the HIV program in Nigeria.

Sexually transmitted infection associated syndromes among pregnant women attending antenatal care clinics in southwest Ethiopia

Background

Sexually transmitted infections (STIs) are widely reported in pregnant women in Africa and can cause significant maternal and perinatal morbidity. The availability of epidemiologic data on STIs and their associated factors in pregnant women is critical to developing effective prevention strategies. Therefore, this study aimed to assess the prevalence and factors associated with sexually transmitted infection-associated syndromes among pregnant women attending antenatal care clinics at selected public health facilities in southwest Ethiopia.

Methods

A cross-sectional study was carried out with 303 pregnant women who attended ANC between November 1 and 30, 2018. The consecutive sampling technique was employed until the required sample size was reached. The data were collected using a structured and pre-tested questionnaire. Bi-variable and multivariate logistic regressions were used to identify independent variables associated with the outcome of interest. The level of significance was declared at a p-value < 0.05.

Results

Of the 303 respondents surveyed, STI-associated syndromes had a prevalence of 19.1% (95% CI: 14.7%–23.5%). Nearly one-tenth (8.9%) of the respondents had vaginal discharge syndrome followed by lower abdominal or pelvic pain (7.6%). The study also found that being unmarried (AOR = 5.61, 95% CI [2.34–9.36]), not formally educated (AOR = 2.24, 95% CI [1.58–3.86]), having multiple sexual partners in the past 3 months (AOR = 3.93, 95% CI [1.44–5.23]), history of spontaneous abortion (AOR = 4.48, 95% CI [2.21–7.72]), and history of STI (AOR = 3.76, 95% CI [2.24–6.46]) were the factors associated with STI-associated syndromes.

Conclusion

The prevalence of STI-associated syndromes among respondents was 19.1%. The study found that being unmarried, not formally educated, having multiple sexual partners, history of spontaneous abortion, and history of STI were largely accountable for the occurrence of STI-associated syndromes in the study sample. Therefore, in addition to the one-time assessment of HIV and syphilis at the first ANC visit, there is a need to emphasize the syndromic approach diagnosis of STIs among pregnant women during each ANC visit to reduce and ultimately prevent both vertical and horizontal transmissions of STIs.

Seroprevalence and Associated Factors of Human Immunodeficiency Virus, Treponema pallidum, Hepatitis B Virus, and Hepatitis C Virus among Female Sex Workers in Dessie City, Northeast Ethiopia

Introduction

Sexually transmitted infections (STIs) are prevalent in Ethiopia and elsewhere among different population groups particularly among female sex workers (FSWs). Because of their work and their behavior, FSWs are at high risk to acquire STIs. The aim of the study was to assess the seroprevalence and associated factors of HIV, HBV, HCV, and T. pallidum among FSWs in Dessie City, Northeast Ethiopia.

Methods

This cross-sectional study was conducted in Dessie City, Amhara Region, Northeastern Ethiopia, from November 2017 to April 2018. A total of 360 FSWs whose age is greater than or equal to 18 years and who are willing to participate were recruited by simple random sampling technique. Interview-based questionnaire was administered, and 5 ml of venous blood from each participant was drawn under aseptic conditions. The rapid test was performed to obtain the result of the four STIs (HIV, T. pallidum, HBV, and HCV). The collected data were entered and analyzed by SPSS version 20.0. From the bivariable analysis, variables having P value < 0.2 were retained into multivariable analysis. From the multivariable analysis, variables with P value < 0.05 were affirmed as statistically associated factors. Adjusted odds ratios and their 95% confidence intervals were used as indicators of the strength of association.

Results

Majority of study participants were urban dwellers, 10 (2.8%) respondents were married, 61 (16.9%) have more than two children, and more than half of them were at the age range between 18 and 27 years. Any infection with STIs was 84 (23.3%), whereas 27 (7.5%), 47 (13.1%), 2 (0.6%), and 45 (12.5%) study participants were positive for laboratory test of HIV, HBV, HCV, and T. pallidum, respectively. Marital status, sharing of sharp materials, breakage of condom, number of customers per week, genital discharge, and pain had significant association with any STI.

Conclusions

In comparison with different research works in Ethiopia and abroad, the prevalence of any STI, HIV, HBV, and T. pallidum was found to be relatively high. Preventive approach and appropriate treatment of STIs should be developed. Concerned body should work together to alleviate the problem by counseling and recruiting them on other productive job sectors in the country.

HIV, hepatitis B virus, hepatitis C virus, and syphilis among pregnant women attending antenatal care in Luanda, Angola: Seroprevalence and risk factors

Infectious diseases during pregnancy remain a public health concern, especially in a resource-limited setting. The study aimed to determine the seroprevalence and determinants of HIV and co-infection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis among pregnant women attending antenatal care in Luanda, the capital city of Angola. A cross-sectional study was conducted with 1612 pregnant women screened for HIV during antenatal care. HIV-reactive were also screened for the HBV, HCV, and syphilis using immunoassay kits. A logistic regression model, adjusted odds ratios (AOR) and their 95% confidence interval (CI) were calculated with a level of significance set at 5%. The overall seroprevalence of HIV was 2.6%. About 13% of HIV-positive pregnant women were coinfected. From which, 7.5% were reactive to HBV and 5% to syphilis. There was no reactivity to HCV. Pregnant women younger aged than 25 years were significantly protected from HIV-infection (AOR, 0.43 [95% CI, 0.20-0.91], P = .026). The co-infection was 1.3 times (AOR, 0.04-41.0) in younger aged than 25 years, 7.0 times (AOR, 0.50-99.2) to residents in urbanized areas, and 1.4 times (AOR, 0.10-20.9) in pregnant women with a high educational level. In conclusion, infectious diseases are a public health burden among pregnant women in Luanda. However, include an integrated antenatal screening mainly in urbanized areas is crucial to reduce the spread of infectious diseases in different communities of Angola.

<p>Risky Sexual Practice, Sexually Transmitted Infection and Associated Factors Among Newly Diagnosed HIV-positive People in Northwest Ethiopia</p>

Purpose

Risky sexual practice expose for the acquisition of sexually transmitted infection (STI) including human immunodeficiency virus (HIV). This study was conducted to fill the knowledge gap on the prevalence of risky sexual practice, STIs and associated factors among newly diagnosed HIV-positive people in northwest Ethiopia.

Patients and Methods

This study was a cross-sectional study design which was conducted on 745 newly diagnosed HIV patients. An interviewer-administered questionnaire was used to interview patients within seven days of HIV diagnosis using client exit interview approach. Data were entered to EpiData and exported to SPSS version 24 for analysis. Binary logistic regression analysis was employed to select factors for multivariate logistic regression at p-value of less than 0.25. Two separate logistic regression models were used for risky sexual practice and STI as dependent variables. The strength of statistical association was quantified using an adjusted odds ratio (AOR) with a 95% confidence level.

Results

The prevalence of risky sexual practices and STIs among newly diagnosed HIV-positive people were 15.8% (95%CI: 13.1–18.4) and 6.6% (95%CI: 4.8–8.5), respectively. Although there were no statistically significant factors associated with STI, having two or more lifetime sexual partners (AOR=3.19; 95%CI: 1.57–6.49) and frequent use of alcohol (AOR=3.10; 95%CI: 1.34–7.19) were the factors associated with risky sexual practice.

Conclusion

Risky sexual practice and STI were found to be low among newly identified HIV patients. Factors associated with risky sexual practice failed to explain STI diagnosis using the syndromic approach. Therefore, revisiting the definition of risky sexual practice is necessary for the universal test and treat approach since sustained viral suppression may leave the need for consistent use of condoms among HIV patients who are on ART especially with regular sexual partners. Further study is also recommended to measure changes in sexual practice after initiating antiretroviral therapy.

Standardized treatment and determinants on 9,059 syphilis-infected pregnant women during 2015-2018 in Hunan, China

This study was aimed to describe the standardized treatment rate of syphilis-infected pregnant women in Hunan province and to explore the determinants for standardized treatment. All syphilis-infected pregnant women registered in the Information System of Prevention of Mother-to-Child Transmission of Syphilis Management (IPMTCT) in Hunan between January 2015 and December 2018 were included in this study. Among 9,059 pregnant women with syphilis, 7,797 received syphilis treatment, with a treatment rate of 86.1%, and 4,963 underwent standardized syphilis treatment, with an average standardized treatment rate of 54.8%. The facilitators for the standardized treatment included abnormal reproductive histories (aOR = 1.15, 95%CI:1.03–1.28), time of first prenatal care within 1–12 weeks (aOR = 5.17, 95%CI:4.19–6.37) or within 13–27 weeks (aOR = 5.56, 95%CI:4.46–6.92), previous syphilis infection (aOR = 1.64, 95%CI: 1.48–1.81), and definite syphilis infection status of sexual partner (negative: aOR = 1.73, 95%CI:1.57–1.91; positive: aOR = 1.62, 95%CI:1.34–1.95). The barriers included marital status being unmarried/divorced/widowed (aOR = 0.81, 95%CI: 0.65–0.99), pluripara (aOR = 0.58, 95%CI: 0.46–0.74), number of children ≥ 2 (aOR = 0.45, 95%CI: 0.35–0.57), and syphilis clinical stage being primary/secondary/tertiary (aOR = 0.72, 95%CI: 0.58–0.88) or unclear (aOR = 0.78, 95%CI: 0.70–0.86). Though the treatment rate of syphilis-infected pregnant women was high, the standardized treatment rate was low. The facilitators and barriers on standardized treatment of gestational syphilis were identified at the patient level.
