Ten-year trends of syphilis in sero-surveillance of pregnant women in Rwanda and correlates of syphilis-HIV co-infection
Syphilis can be transmitted by pregnant women to their children and is a public health problem in Africa. A cross-sectional survey was conducted in 24 antenatal clinics from 2002 to 2003 and increased to 30 sites from 2005 to 2011. Participants were tested for syphilis and HIV. Multi-variate logistic regression was performed to identify risks associated with syphilis and its co-infection with HIV. Results showed that syphilis decreased from 3.8% in 2002 to 2.0% in 2011. Syphilis in the HIV-infected participants increased from 6.0% in 2002 to 10.8% in 2011, but decreased from 3.7% to 1.7% in the HIV-negative participants. In 2011, syphilis in urban participants was 2.7% and 1.4% in rural ones. HIV-infected participants screened positive for syphilis more frequently in both rural (aOR = 3.64 [95% CI: 1.56%-8.51%]) and urban areas (aOR = 7.26 [95% CI: 5.04%-10.46%]). Older participants (25-49 years) residing in urban areas (aOR = 0.43[95% CI: 0.32%-0.58%]) and women with secondary or high education (aOR = 0.35[95% CI: 0.20%-0.62%]) were less likely to screen positive for syphilis. HIV-syphilis co-infection was more likely in women residing in urban areas (aOR = 8.32[95% CI: 3.54%-19.56%]), but less likely in women with secondary/high education (aOR = 0.11[95% CI: 0.01%-0.77%]). In conclusion, syphilis increased in HIV-positive pregnant women, but decreased in HIV-negative women. Positive HIV status and young age were associated risks for syphilis. HIV-syphilis co-infection was associated with a lower level of education and urban residence
Hepatitis B virus and HIV co-infection among pregnant women in Rwanda
Background
Hepatitis B virus (HBV) affects people worldwide but the local burden especially in pregnant women and their new born babies is unknown. In Rwanda HIV-infected individuals who are also infected with HBV are supposed to be initiated on ART immediately. HBV is easily transmitted from mother to child during delivery. We sought to estimate the prevalence of chronic HBV infection among pregnant women attending ante-natal clinic (ANC) in Rwanda and to determine factors associated with HBV and HIV co-infection.
Methods
This study used a cross-sectional survey, targeting pregnant women in sentinel sites. Pregnant women were tested for hepatitis B surface antigen (HBsAg) and HIV infection. A series of tests were done to ensure high sensitivity. Multivariable logistic regression was used to identify independent predictors of HBV-HIV co-infection among those collected during ANC sentinel surveillance, these included: age, marital status, education level, occupation, residence, pregnancy and syphilis infection.
Results
The prevalence of HBsAg among 13,121 pregnant women was 3.7% (95% CI: 3.4–4.0%) and was similar among different socio-demographic characteristics that were assessed. The proportion of HIV-infection among HBsAg-positive pregnant women was 4.1% [95% CI: 2.5–6.3%]. The prevalence of HBV-HIV co-infection was higher among women aged 15-24 years compared to those women aged 25–49 years [aOR = 6.9 (95% CI: 1.8–27.0)]. Women residing in urban areas seemed having HBV-HIV co-infection compared with women residing in rural areas [aOR = 4.3 (95% CI: 1.2–16.4)]. Women with more than two pregnancies were potentially having the co-infection compared to those with two or less (aOR = 6.9 (95% CI: 1.7–27.8). Women with RPR-positive test were seemed associated with HBV-HIV co-infection (aOR = 24.9 (95% CI: 5.0–122.9).
Conclusion
Chronic HBV infection is a public health problem among pregnant women in Rwanda. Understanding that HBV-HIV co-infection may be more prominent in younger women from urban residences will help inform and strengthen HBV prevention and treatment programmes among HIV-infected pregnant women, which is crucial to this population.Medicine, Faculty ofNon UBCPopulation and Public Health (SPPH), School ofReviewedFacult
Ten-year trends of syphilis in sero-surveillance of pregnant women in Rwanda and correlates of syphilis-HIV co-infection
HIV surveillance in Rwanda: readiness assessment to transition from antenatal care-based to prevention of mother-to-child transmission program-based HIV surveillance
SummaryBackgroundIn 2013, the World Health Organization (WHO) recommended that for efficiency and ethical considerations, transitioning from antenatal clinic-based surveillance to prevention of mother-to-child transmission (PMTCT)-based routine data should be investigated. An assessment of the readiness for this transition was carried out in Rwanda in 2011 and 2013.MethodsThis assessment applied the WHO recommended method. Individual HIV rapid testing at site was compared to antenatal surveillance results at all existing 30 sites, involving 13 292 women. In addition, PMTCT HIV testing quality assurance and PMTCT routine data quality were assessed at 27 out of the 30 sites.ResultsAll sentinel sites provided PMTCT services and had a high uptake of HIV testing (more than 90%). At all sites, PMTCT data were recorded in longitudinal and standardized antenatal clinic registers. Twenty-six out of 27 sites had HIV result completeness above 90%. A positive percentage agreement of 97.5% and negative percentage agreement of 99.9% were observed between routine PMTCT and sero-surveillance HIV test results. Of 27 sites, 25 scored more than 80% in all phases of HIV testing quality assurance.ConclusionsAccording to WHO standards, Rwanda antenatal care HIV sero-surveillance is ready to transition to PMTCT-based sero-surveillance
