Preeclampsia (PE) affects 2 to 8% of pregnant women and represents one of the major causes of maternal and perinatal morbidity and mortality, particularly in sub-Saharan Africa. A limited number of biomarkers have been proposed for the identification of pregnant women predisposed to preeclampsia. Syncytin-2 is an endogenous retrovirus envelope protein playing a key role in placental formation through the fusion of villous cytotrophoblasts, resulting in syncytiotrophoblast formation. The reduction of Syncytin-2 levels detected in placental tissue and on the surface of exosomes has been shown to strongly correlate with the severity of symptoms in preeclamptic patients. We were thus interested in conducting an analysis of a Benin cohort of pregnant women over the predictive value of this marker. From July 2015 to January 2017, 260 pregnant women were recruited in two health facilities. Blood samples were monthly collected from the beginning of pregnancy up to 20 weeks of gestation and exosomes were then isolated. We then compared Syncytin-2 levels in exosome preparations from women who presented PE to those with normal pregnancy. Our results showed that Syncytin-2 significantly decreased between 7 to 10 weeks of gestation in pregnant women with PE compared to normal pregnant women (p=0.02). Our study thereby suggests that Syncytin-2 could be a promising biomarker for early diagnosis of PE.

Malaria still remains a challenging infection affecting the lives of several HIV infected pregnant women in sub-Saharan Africa. This study was undertaken to determine malarial infection in HIV infected pregnant women in relation to sociodemographic and obstetrical factors. The study also assessed relationship between malarial infection and haemoglobin level, CD4+ counts, and ART regimen, as well as predisposing risk factors that influenced occurrence of malarial infection in the women. Thick and thin blood smears were prepared and stained with Giemsa. Haemoglobin level was determined using a hematology analyzer, while the flow cytometry was used to measure CD4+ counts. Sociodemographic and obstetrical parameters were obtained through the administration of questionnaires. Of the 159 HIV infected pregnant women examined, 33.3% (59/159) had malarial infection. Malarial infection was significantly higher in pregnant women who were divorced, 40.24% (33/82) (χ2=5.72; P=0.05), were at their first trimester (4–12 weeks), 54.8% (17/31) (χ2=14.85; P=0.01), had CD4+ = [201–500 cells/μL], 42.42% (42/99) (χ2=10.13; P=0.00), and those that had severe anaemia (<8 dg/L), 100.00% (χ2= 45.75; P=0.00). However, risk factors that influenced the occurrence of malarial infection in the pregnant women were occupation (farming) (AOR=0.226; P=0.03), marital status (divorced) (AOR=2.80; P=0.02), gestation (first trimester) (AOR=0.33; P=0.00), haemoglobin level (Hb < 8 dg/L) (AOR=0.02; P=0.00), and CD4+ counts (low CD4+) (OR=0.40; P=0.05). The study reported endemicity of malaria in HIV infected pregnant women living in rural areas of Benue State, Nigeria. Malarial infection was higher in women that were divorced, and at their first trimester, had low CD4+ count, and had severe anaemia. Farming, divorce, gestation, severe anaemia, and low CD4+ counts were predisposing risk factors that influenced malaria occurrence in the HIV infected pregnant women. It is advocated that HIV infected pregnant women should be properly and thoroughly educated on malaria preventive measures in rural areas so as to avoid unpleasant effect of malaria during their pregnancies.

Abstract Background Malaria in pregnancy is a crucial public health concern due to the enormous risk it poses to maternal and newborn health. The World Health Organisation therefore recommends insecticide-treated net (ITN) for pregnant women. The world over, sub-Saharan Africa bears the highest prevalence of malaria and its associated complications. This study investigated the individual, community and society level factors associated with ITN use among pregnant women in sub-Saharan Africa. Methods The study was conducted with Demographic and Health Survey data of 21 sub-Saharan African countries. A total of 17,731 pregnant women who possessed ITN participated in the study. Descriptive computation of ITN use by survey country and socio-demographic characteristics was conducted. Further, five multi-level binary logistic regression models were fitted with MLwiN 3.05 package in STATA. The Markov Chain Monte Carlo (MCMC) estimation procedure was used in estimating the parameters whilst the Bayesian Deviance Information Criterion was used for the model fitness test. Results On average, 74.2% pregnant women in SSA used ITN. The highest prevalence of ITN use occurred in Mali (83.7%) whilst the least usage occurred in Namibia (7%). Women aged 30–34 were more likely to use ITN compared with those aged 45–49 [aOR = 1.14; Crl = 1.07–1.50]. Poorest women were less probable to use ITN relative to richest women [aOR = 0.79; Crl = 0.70–0.89]. Compared to women who did not want their pregnancies at all, women who wanted their pregnancies [aOR = 1.06; Crl = 1.04–1.19] were more probable to use ITN. Women in male-headed households had higher likelihood of ITN use compared to those from female-headed households [aOR = 1.28; Crl = 1.19–1.39]. On the whole, 38.1% variation in ITN use was attributable to societal level factors whilst 20.9% variation was attributable to community level factors. Conclusion The study has revealed that in addition to individual level factors, community and society level factors affect ITN use in SSA. In as much as the study points towards the need to incorporate community and societal variations in ITN interventions, active involvement of men can yield better outcome for ITN utilisation interventions in SSA.

Nigeria is one of the high-burden countries in sub-Saharan Africa for HIV/AIDS and contributes to reproductive health morbidities and mortalities. This study was aimed at determining the prevalence of HIV-discordant rate among pregnant women in Plateau state Nigeria. The study sought to determine the prevalence and trend of HIV sero-discordance among pregnant women in Plateau state, Nigeria. The study was a 5-year descriptive analysis of HIV sero-discordance among pregnant women accessing prenatal care and their partners in Plateau state, Nigeria based on data generated between January 2012 and December 2016. The data was disaggregated by year, HIV concordant negative, HIV concordant positive, and HIV sero-discordant prevalence in the software and analysis were done using excel to obtained the proportions and trend of HIV sero-discordant prevalence among the antenatal population. Out of a total of 7,851 partners of pregnant women studied, 969 (16.3%) were HIV sero-discordant, 5,795 (73.8%) were HIV concordant negative, and 773 (9.9%) were HIV concordant positive. HIV sero-discordant positive males accounted for 12.3% while females were 4.0%. The prevalence of HIV sero-discordance was low with a high proportion of HIV positive male partners in Plateau state with grave public health implications for new HIV infections among partners and eroding the gains made in the Prevention of mother-to-child transmission of HIV.

Abstract In sub-Saharan Africa little is known about how often women use pregnancy self-tests or characteristics of these women despite evidence that pregnancy self-testing is associated with early antenatal care (ANC) attendance. Understanding the characteristics of women who use pregnancy self-tests may facilitate early access to ANC and preventive interventions in pregnancy. We conducted a cross-sectional survey on an ongoing pre-exposure prophylaxis (PrEP) implementation study which enrolled pregnant women to determine the prevalence and factors associated with pregnancy self-testing among women in western Kenya. Overall in our study population, the prevalence of pregnancy self-testing was 22% and higher among women who were employed, currently in school, had previous pregnancy complications, received services from urban health facilities, and had partners who had at least attended secondary school. The most reported reasons for non-use of pregnancy self-tests included not thinking it was necessary, lack of knowledge, and lack of money to pay for the test. Future research should focus on understanding the knowledge and attitudes of women toward pregnancy self-testing.

Background Anemia is one of the world’s leading cause of disability and the most serious global public health issues. This systematic review and meta-analysis was conducted very carefully in order to give up the pooled compliance of Iron and Folic-Acid Supplementation in Sub-Saharan Africa. Methods To conduct this brief systematic review and meta-analysis, a related literature search was done from different sources, PubMed Medline and Google Scholar Journals. Then IFA Supplementation related searching engine was used to make the work more meaningful and intensive. Moreover, we used modified Newcastle-Ottawa quality assessment scale for cross sectional studies to assess the quality of the study in terms of their inclusion. Then, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed to carry out the work in a carful manner. Finally, the pooled effect size was computed using the review manager and Compressive Meta-analysis software. Results Twenty-three studies, which encompassed 24272 pregnant women, were chosen for the analysis. From those an overall prevalence of compliance with Iron and Folic Acid Supplementation (IFAS) in pregnancy in SSA was 39.2%. However, the result from meta-analysis showed that women who were counseled on IFAS in their courses of pregnancy were 1.96 times more likely to adhere to IFAS compared to those who were not counseled [OR:1.96, 95% CI (1.76-,5.93)]. Moreover, it showed that women who had knowledge of IFAS were 2.71 times more likely to have compliance with IFAS as compared to those who had no knowledge of IFAS [OR:2.71, 95% CI (1.33,5.54)]. Also it revealed that those women who had knowledge of anemia were 5.42 times more likely to have compliance with IFAS as compared with those who had no knowledge of anemia [OR5.42, 95% CI (1.52, 19.43)]. Furthermore, women who had received fourth visit for ANC were 1.54 times more likely to have compliance with IFAS as compared to those who had not received for ANC [OR 1.54, 95% CI (0.66, 3.58.43)]. Conclusions Our finding from this systematic review and meta-analysis shows the low case in prevalence of compliance to IFAS among pregnant women in SSA. Predictors for this includes: knowledge about anemia, knowledge about IFAS, counseling on IFAS and receiving fourth antenatal care visit were statistically correlated positively with compliance to IFAS. This demands careful appraisal of effect of prevention work for functioning policy, programs and plan nutrition intrusions for refining maternal dietary intake in gestation. Also dietary education intrusion requires to be planned to satisfy the needs of pregnant women. So we hope that the result of this study might be essential as a bridging stone for policy makers of Africa; exclusively for maternal and child health care. Finally, we recommended further studies to be conducted in the area of the study for more intensive and detailed suggestions.

BACKGROUND: According to the theory of endothelial dysfunction, the pathogenesis of preeclampsia is associated with the imbalance of angiogenic and anti-angiogenic factors. Transforming growth factor-beta 1 (TGF-β1) has also proposed as a proangiogenic factor that influences preeclampsia. This study was conducted to compare a mean difference of TGF-β1 between preeclampsia and normal pregnancy.METHODS: This study was an observational crosssectional study with 25 subjects of pregnant women with preeclampsia and 25 subjects of normotensive pregnant women. The study was conducted in Dr. Reksodiwiryo Hospital, Bhayangkara Hospital, and Dr. Rasidin Hospital in Padang, Indonesia from October 2015 to January 2016. For the determination of TGF-β1 concentration, peripheral Abstract venous blood samples were taken. The blood samples wereanalyzed by enzyme-linked immunosorbent assay (ELISA) in Biomedical Laboratory, Faculty of Medicine, Andalas University. The mean difference was statically analyzed by independent samples T-test.RESULTS: The mean difference of TGF-β1 was lower in preeclampsia group than normal pregnancy group (2.02±0.99 ng/mL vs. 3.24±2.67 ng/mL; p<0.05).CONCLUSION: The TGF-β1 concentration was lower in pregnant women with preeclampsia. Thus, it may have a role as a marker in preeclampsia.KEYWORDS: preeclampsia, normal pregnancy, transforming growth factor-beta1, TGF-β1

The aims of this study were to present and discuss ultrasound findings of prenatal fetal cholelithiasis in two cases with different etiology and evolution. Case 1: a pregnant woman from sub-Saharan Africa, suffering from Lyme disease, was treated with ceftriaxone sodium. Six weeks later, biliary sludge associated with polyhydramnios was detected in the fetus and the fetal growth percentile was 14. Emergency caesarean was performed at 36 weeks of gestation due to fetal distress. Biliary sludge persists in the two-and-a-half-year-old child. Case 2: the fetus of a Caucasian woman with normal pregnancy showed multiple cholelithiasis associated with polyhydramnios at 31 weeks of gestation. At 39 weeks and 4 days, cesarean section was performed due to lack of dilation. The biliary disease resolved spontaneously at seven months of age, with no associated abnormalities. In conclusion, prenatal diagnosis of cholelithiasis is straightforward, but prognosis cannot be defined yet. Serious complications do not arise in 70% of cases, but severe diseases may ensue in 20%. Persistence of cholelithiasis after one year of age results in cholelithiasis in childhood and beyond. Biliary sludge is associated with worse prognosis than cholelithiasis when it appears before 28 weeks of gestation.
