Gedefie A, Shimeles G, Motbainor H, Kassanew B, Genet C. Vaginal colonization and vertical transmission of Candida species: prevalence and associated factors among pregnant women and their neonates at public health facilities of Northeast Ethiopia. BMC Pregnancy Childbirth 2025; 25:22. [PMID: 39789438 PMCID: PMC11716415 DOI: 10.1186/s12884-024-07103-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2024] [Accepted: 12/23/2024] [Indexed: 01/12/2025] Open
Abstract
BACKGROUND Vaginal colonization by Candida can lead to vulvovaginal candidiasis, which is the second most prevalent vaginal condition globally. It is frequently associated with sepsis and adverse neonatal outcomes in pregnant women. This issue is worsening in Sub-Saharan Africa, including Ethiopia. However, evidence of the existing problem is very scarce yet crucial. Thus, this study aimed to determine the vaginal colonization and vertical transmission of Candida species and their associated factors among pregnant women and their neonates in public health facilities of northeast Ethiopia. METHODS A facility-based cross-sectional study was conducted at selected public health facilities in Dessie town from April 1 to June 30, 2023, among 348 pregnant women and their newborns, using convenience sampling techniques. Socio-demographic, and clinical-related data were collected using a pre-tested, semi-structured questionnaire. Vaginal swab samples from pregnant women and pooled swabs from the external ear, nasal area, and umbilical areas of the newborns were collected and transported using Amies transport media. The samples were inoculated into Sabouraud Dextrose Agar for isolation, followed by inoculation onto a standard CHROM agar Candida plate for species identification, and a germ-tube test confirmed pseudophyphae of C.albicans. Data was entered into Epi Data version 4.6.0 software and exported and analyzed by SPSS version 25.0. A stepwise logistic regression model was used to identify the associated factors. Variables with p < 0.05 and their 95% confidence interval were considered statistically significant. RESULT A total of 348 pregnant women attending vaginal delivery were included in the study. The maternal and neonatal colonization rates of Candida species were 14.1% (49/348) and 6.3% (22/348), respectively. The overall proportion of vertical transmission of Candida species was 44.9% (22/49, 95% CI: 41.2, 49.7). Among Candida isolates, 63.3% (31/49) were C. albicans and 36.7% (18/49) were C. krusei. Gestational diabetes mellitus (AOR: 4.2, 95% CI: 1.23-38.6, P = 0.047) and HIV (AOR: 1.58, 95% CI: 1.11-6.12, P = 0.049) were independently associated with maternal colonization of Candida species. Moreover, rural residence (AOR = 3.6, 95% CI: 1.37-9.5, P = 0.010) and maternal age above 28 years (AOR = 2.39, 95% CI: 1.97-5.89, P = 0.048) were independently associated with vertical transmission of Candida species. CONCLUSION The findings of this study highlight the need for effective screening and treatment of Candida colonization during antenatal care.

Malindi FC, Maputle MS. Involvement of Male Partners in Sustaining Interventions for Preventing Mother-to-Child Transmission of HIV Among Women with HIV. Int J MCH AIDS 2024; 13:e023. [PMID: 39526166 PMCID: PMC11544484 DOI: 10.25259/ijma_645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 05/31/2024] [Indexed: 11/16/2024] Open
Abstract
Background and Objective Although male partners are eager to support the implementation of prevention of mother-to-child transmission (PMTCT) of HIV programs, several obstacles prevent them from participating. The purpose of this study was to explore the support of male partners of HIV-positive women in sustaining the implementation of PMTCT interventions. Methods This study adopted a qualitative approach. The case study research design was used to generate an in-depth understanding of the factors that hinder male participation in PMTCT interventions. Non-probability purposive sampling was used to 20 sample participants. Data was collected from two focus group discussions and analyzed using open coding. Trustworthiness was achieved by credibility, transferability, and confirmability. Adherence to ethical principles was upheld. Results Findings revealed two themes, perceived practices that hinder the provision of support and perceived support provided to sustain PMTCT intervention during childbirth. Sustaining PMTCT interventions included how the male partner adheres to interventions that prevent the transmission of the virus, like consistent condom use, especially during breastfeeding, support in exclusive breastfeeding, adherence to ART, and limiting the use of cultural practices. Conclusion and Global Health Implications The involvement of males in the interventions of PMTCT has been found to improve the sustainability of eliminating transmission of the virus to the baby. All clinics were recommended to be men user-friendly to encourage men to accompany their partners. Men are to be actively involved during decision-making and physical examination, where possible. Workshops and information-sharing sessions for men forums and community members on PMTCT interventions to be conducted.

Abstract
Background and Objective Understanding the preferences of women living with HIV (WLH) for the prevention of mother-to-child HIV transmission (PMTCT) services is important to ensure such services are person-centered. Methods From April to December 2022, we surveyed pregnant and postpartum WLH enrolled at five health facilities in western Kenya to understand their preferences for PMTCT services. WLH were stratified based on the timing of HIV diagnosis: known HIV-positive (KHP; before antenatal clinic [ANC] enrollment), newly HIV-positive (NHP; on/after ANC enrollment). Multivariable logistic regression was used to determine associations between various service preferences and NHP (vs. KHP) status, controlling for age, facility, gravidity, retention status, and pregnancy status. Results Among 250 participants (median age 31 years, 31% NHP, 69% KHP), 93% preferred integrated versus non-integrated HIV and maternal-child health (MCH) services; 37% preferred male partners attend at least one ANC appointment (vs. no attendance/no preference); 54% preferred support groups (vs. no groups; 96% preferred facility - over community-based groups); and, preferences for groups was lower among NHP (42%) versus KHP (60%). NHP had lower odds of preferring support groups versus KHP (aOR 0.45, 95% CI 0.25-0.82), but not the other services. Conclusion and Global Health Implications Integrated services were highly preferred by WLH, supporting the current PMTCT service model in Kenya. Further research is needed to explore the implementation of facility-based support groups for WLH as well as the reasons underlying women's preferences.

Efficacy and safety of tenofovir disoproxil fumarate or telbivudine used throughout pregnancy for the prevention of mother-to-child transmission of hepatitis B virus: A cohort study. Eur J Obstet Gynecol Reprod Biol 2022; 276:102-106. [PMID: 35853269 DOI: 10.1016/j.ejogrb.2022.07.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 07/06/2022] [Accepted: 07/11/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Tenofovir disoproxil fumarate (TDF) use compared with telbivudine (LdT) use throughout pregnancy has not been adequately investigated. To compare the efficacy and safety of TDF and LdT for the prevention of mother-to-child transmission (MTCT) of hepatitis B from highly viremic mothers throughout pregnancy in real-world settings. STUDY DESIGN This was a single-center, retrospective cohort study. From January 1, 2013, to December 31, 2018, we retrospectively enrolled 602 mothers with chronic hepatitis B (CHB) who received antiviral treatment throughout pregnancy at Beijing Ditan Hospital. A total of 562 mothers met the inclusion criteria, with 167 in the TDF group and 395 in the LdT group. Mothers and infants were followed for 28 weeks postpartum. The primary endpoint was the MTCT rate of HBV. The secondary endpoints were the safety profiles in mothers and infants. RESULTS The MTCT rates were 0 % in both the TDF and LdT groups. The rates of neonatal congenital abnormalities were similar between the TDF and LdT groups (1.2 % vs 1.8 %, P = 0.896). There were no significant differences in perinatal complications between the two groups (all P > 0.05). There were also no significant differences in gestational age or infant height, weight, Apgar score. The level of HBV DNA at 28 weeks postpartum was an independent risk factor for postpartum alanine aminotransferase (ALT) flares (OR = 2.348, 95 % CI: 1.100-5.016, P = 0.027). CONCLUSION TDF and LdT treatments throughout pregnancy in mothers with CHB were equally effective in preventing MTCT and safe.

Abstract
INTRODUCTION Even though the risk of COVID-19 in pregnancy may be increased, large-scale studies are needed to better understand the impact of the infection in this population. The aim of this study is to describe obstetric complications and the rate of vertical transmission in pregnant women with SARS-CoV-2 infection. MATERIAL AND METHODS Detected cases of SARS-CoV-2 infection in pregnancy were registered in Portuguese hospitals by obstetricians. Epidemiological, pregnancy and childbirth data were collected. RESULTS There were 630 positive cases in 23 Portuguese maternity hospitals, most at term (87.9%) and asymptomatic (62.9%). The most frequent maternal comorbidity was obesity. The rates of preterm birth and small-to-gestational-age were 12.1% and 9.9%, respectively. In the third trimester, 2.9% of pregnant women required respiratory support. There were eight cases (1.5%) of fetal death, including two cases of vertical transmission. There were five cases of postpartum respiratory degradation, but no maternal deaths were recorded. The caesarean section rate was higher in the first than in the second wave (68.5% vs 31.5%). RT-PCR SARS-CoV-2 positivity among newborns was 1.3%. CONCLUSION SARS-Cov-2 infection in pregnancy may carry increased risks for both pregnant women and the fetuses. Individualized surveillance and the prophylaxis of this population with vaccination. is recommended in these cases.

Abstract
An overlooked endemic zoonosis in Africa, monkeypox infection, which has spread to multiple non-endemic countries since early May 2022, was declared a Public Health Emergency of International Concern by the World Health Organization on July 23, 2022. As of August 8, 2022, over 28,000 confirmed and probable monkeypox cases were reported globally, including 6 deaths from the African continent and 4 deaths from the non-endemic regions. Although the current outbreak mostly belongs to the West African clade, which has a lower-case fatality ratio of <1%, there is limited data among immune-weakened individuals infected with monkeypox. It is still unknown if pregnant people are more susceptible to monkeypox. In addition, it is unclear whether having monkeypox increases the risk of birth defects. This commentary addresses reported cases of monkeypox infection in pregnancy and the possible maternal and fetal outcomes, including congenital monkeypox, miscarriage, or stillbirth. Factors behind the escalating global monkeypox outbreak, as well as the prevention and control of monkeypox via the One Health approach, are discussed to shed light on curbing the continuous emergence of monkeypox.

Abstract
BACKGROUND The emergence and fast spread of coronavirus disease 2019 (COVID-19) threatens the world as a new public health crisis. Little is known about its effects during pregnancy. This study aimed to investigate the clinical manifestations of COVID-19 on maternal and neonatal outcomes. METHODS In this systematic review, PubMed, Scopus, Web of Science, and Google Scholar databases were searched focusing on pregnancy and perinatal outcomes of COVID-19. RESULTS The initial search yielded 1236 articles, from which finally 21 unique studies, involving 151 pregnant women and 17 neonates, met the criteria. Mean ± SD age of included mothers and mean ± SD gestational age at admission were 30.6 ± 6.2 years and 30.8 ± 8.9 weeks, respectively. The common symptoms were fever, cough, fatigue, dyspnea and myalgia. The mortality rates of pregnant women and neonates were 28 out of 151 (18.5%) and 4 out of 17 (23.5%), respectively. Most of the neonates were preterm at the time of delivery. Three neonates had positive RT-PCR test on the first day after birth and three others on day two. On the average, neonate's PCR became positive on day 4 for the first time. CONCLUSION Early diagnosis of COVID-19 is crucial due to the possibility of the prenatal complications. Strict prevention strategies may reduce the risk of mother to infant transmission.

Abstract
The low rate of screening for hepatitis B virus (HBV) in pregnant women is a highrisk factor for its vertical transmission. The objectives of this study were: i) to screen pregnant women for HBV infection; ii) vaccinate all children from birth against HBV regardless their mother HBV status; and iii) evaluate after 7 months of birth the level of their AbHBs among babies who received HBV vaccine at birth. Serological markers of HBV (HBsAg, HBeAg, AbHBs, AbHBe, and AbHBc) were determined on venous blood samples from 237 pregnant women and their children using the Abon Biopharm Kit. One hundred and two (102) children received the three doses of the EUVAX B® vaccine respectively at birth, two months and four months of life. Seven months after delivery, venous blood samples were collected from mothers and their children. Antibodies against hepatitis B surface antigen (AbHBs) were measured in vaccinated children using the ELISA Kit AbHBs Quantitative EIA. DNA extraction was performed on samples from HBV-seropositive mothers and their children using the Ribo Virus (HBV Real-TM Qual) Kit and for Real Time PCR, the HBV Real-TM Qual Kit was used. Serological diagnosis in pregnant women revealed 22 (9.28%) hepatitis B surface antigen (HBsAg) positive samples of which 21 were positive for viral DNA by real-time PCR. Among the 22 HBsAg+ women, five (05) transmitted the virus to their children with a vertical transmission rate of 22.73%. A transmission rate of 23.81% (5/21) was found with the PCR method. Analysis of AbHBs levels revealed that 98.31% of the children had an average concentration of 218.07 ± 74.66 IU/L, which is well above the minimum threshold for protection (11 IU/L). This study has confirmed that vertical transmission of HBV is a reality in Burkina Faso and that vaccination at birth would significantly reduce this transmission.

Abstract
OBJECTIVE To determine the prevalence of Hepatitis B Virus (HBV) infection in pregnant women and identify markers associated with vertical transmission of HBV. METHODS Prospective and cross-sectional study over 10 months on 298 pregnant women attending antenatal clinics in the Cité Verte and Efoulan District hospitals in Cameroon. A dry tube blood collection was performed on all pregnant women and babies born to HBsAg-positive mothers. Serum from the women was used to test for HBsAg through immunochromatography and then confirmed by ELISA. The test for HBeAg, HBeAb and HBcAb and dosage of transaminases were performed on the serum of HBsAg-positive women. Only HBsAg was tested in babies within 24 hours after birth. RESULTS HBsAg was present in 23 (7.7%) mothers while 275 (92.3%) tested negative. Due to loss to follow-up, we assessed vertical transmission in 20 babies born to20 mothers. In all, eight babies tested HBsAg-positive; six mothers tested positive with HBeAg; 10 mothers with HBeAb and two were simultaneously infected with HBV and HIV. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS HBeAg and increase in liver transaminases were serum markers associated with the vertical transmission of HBV while HBeAb and anti-HIV therapy were protective markers. There is need to systematically screen all pregnant women for hepatitis B, follow up those that are positive, and administer a dose of gammaglobulin anti-HBs to their children to reduce the risks of chronic hepatitis and hepatocellular carcinoma (CHC) and curb mortality and morbidity due to viral hepatitis B.

Abstract
Chronic hepatitis B is a worldwide disease, with significant burden on health care systems. While universal vaccination programs have led to an overall decrease in incidence of transmission of hepatitis B, unfortunately, there remain large areas in the world where vaccination against hepatitis B is not practiced. In addition, vertical transmission of hepatitis B persists as a major concern. Hepatitis B treatment of the pregnant patient requires a thorough assessment of disease activity and close monitoring for flares, regardless of initiation of antiviral therapy. We discuss, in this article, the current and emergent strategies which aim to reduce the rate of transmission of hepatitis B from the pregnant mother to the infant and we review the updated guidelines regarding management of liver disease in pregnant women with hepatitis B.

Abstract
Context: Neonatal conjunctivitis is associated with poor prenatal care worldwide. Purpose: Data on neonatal conjunctivitis is scarce in Malawi. This study describes risk factors associated with conjunctivitis in neonates born in a large tertiary care hospital in Blantyre, Malawi. Materials and Methods: Medical records of a retrospective cohort of 231 neonates diagnosed with conjunctivitis from January 2006 to December 2009 at a large tertiary hospital in Malawi were reviewed. All subjects were clinically diagnosed with ophthalmia neonatorum. Data were collected on patient demographics and clinical features. The frequencies were calculated of various risk factors in neonates with ophthalmia neonatorum and their mothers as well as the treatments administered. Results: Mean age of the mother was 23.45 years (range, 15-40 years), and the mean number of previous deliveries was 2.3 (range, 1-7) children. Nearly, 80% of mothers delivered preterm infants via spontaneous vaginal delivery. The mean birth weight of neonates was 2869.6 grams (1100-5000 grams). Among mothers, premature rupture of membranes was the leading risk factor (24%) followed by sepsis during labor (9%), and history of sexually transmitted infections (STI) (7%). Neonates presented with low Apgar scores (19%), fever (8%), and/or meconium aspiration (5%). Providers treated patients empirically with a varied combination of benzyl penicillin, gentamicin, tetracycline eye ointment, and saline eye wash. Tetracycline with a saline eyewash was used frequently (34%) compared with combinations of benzyl penicillin and gentamicin. Conclusions: Improving prenatal care to reduce sepsis, traumatic deliveries, and early diagnosis of STI with appropriate treatment may potentially reduce vertical transmission of neonatal conjunctivitis in this understudied population.

Abstract
BACKGROUND Little information is available about the timing of mother-to-child transmission of hepatitis C virus (HCV), and no interventions to decrease transmission rates have been identified. We examined the effect of risk factors, including mode of delivery, on the vertical transmission rate. METHODS Data from HCV-infected women and their infants from three hospitals in Ireland and from a British Paediatric Surveillance Unit study of infants born to HCV-infected mothers were used to estimate the vertical transmission rate and risk factors for transmission. We used a probabilistic model using methods that simultaneously estimated the time to HCV-antibody loss in uninfected infants and the diagnostic accuracy of PCR tests for HCV RNA. FINDINGS 441 mother-child pairs from the UK (227) and Ireland (214) were included. 50% of uninfected children became HCV-antibody negative by 8 months and 95% by 13 months. The estimated specificity of PCR for HCV RNA was 97% (95% CI 96-99) and was unrelated to age; sensitivity was only 22% (7-46) in the first month but rose sharply to 97% (85-100) thereafter. The vertical transmission rate was 6.7% (4.1-10.2) overall, and 3.8 times higher in HIV coinfected (n=22) than in HIV-negative women after adjustment for other factors (p=0.06). No effect of breastfeeding on transmission was observed, although only 59 women breastfed. However, delivery by elective caesarean section before membrane rupture was associated with a lower transmission risk than vaginal or emergency caesarean-section delivery (odds ratio 0 [0-0.87], p=0.04, after adjustment for other factors). INTERPRETATION The low sensitivity of HCV RNA soon after birth and the finding of a lower transmission rate after delivery by elective caesarean section suggest that HCV transmission occurs predominantly around the time of delivery. If the findings on elective caesarean section are confirmed in other studies, the case for antenatal HCV testing should be reconsidered.

Abstract
This study determines the factors which correlate with attitudes towards mother-to-child transmission of HIV in pregnant women. Using a structured questionnaire, 527 pregnant women who visited a hospital to have prenatal checkups were interviewed. The survey items were: sociodemographic characteristics, experiences of pre-test counselling, knowledge of mother-to-child transmission, and attitude towards termination of pregnancy. Results showed that many pregnant women (80%) did not have proper knowledge of the possibility of mother-to-child transmission. Logistic regression analysis also indicates that age and knowledge of the possibility of mother-to-child transmission were the significant determinants of attitudes towards termination of pregnancy. Older women who believe that all the babies of pregnant women with HIV will be infected are most likely to terminate their pregnancy when they are diagnosed as HIV positive. Considering the importance of informed decisions regarding pregnancy, this study must have important implications for future support programmes for HIV-positive pregnant women.

Abstract
While international guidelines are currently being drawn up about HIV and infant feeding practices, and national and regional guidelines are under discussion in South Africa, there have been remarkably few studies that have sought to elicit HIV-positive mothers' experiences of breastfeeding and of paediatric infection. There is an urgent need to document this 'grass roots' knowledge in different sites, and for this data to be used to inform policy development, and for advocacy and counselling purposes. This qualitative investigation reports on the experiences and decisions taken around breastfeeding by a peer support group of 13 HIV-positive mothers meeting at King Edward VIII Hospital, Durban. In this study, the particular focus of information-giving and decision-making as to breast or formula feed is concerned with the impact on individual HIV-positive women and their babies. The most significant finding is that at no stage during their pregnancy were any of these mothers given information about the risks of HIV transmission through breastmilk. The study data were elicited in an in-depth group discussion, and individual women were invited to re-enact their stories in a follow-up discussion for clarification purposes. The women also discussed how they dealt with problems surrounding confidentiality in cases where few have been able to disclose their status to the extended family. There have been renewed calls for further investment in counsellors, with an enhanced role for community activists as peer educators. While there are severe resource constraints and low morale among many overworked nurses, one of the general problems in hospital settings remains the vertical health paradigm. This does not accommodate women's experiences, preferences, social networks and lay knowledge, and inhibits many women from becoming full participants in decisions affecting their own and their family's health.

Abstract
BACKGROUND The AIDS Clinical Trials Group protocol 076 zidovudine prophylaxis regimen for HIV-1-infected pregnant women and their babies has been associated with a significant decrease in vertical HIV-1 transmission in non-breastfeeding women in developed countries. We compared the safety and efficacy of short-course nevirapine or zidovudine during labour and the first week of life. METHODS From November, 1997, to April, 1999, we enrolled 626 HIV-1-infected pregnant women at Mulago Hospital in Kampala, Uganda. We randomly assigned mothers nevirapine 200 mg orally at onset of labour and 2 mg/kg to babies within 72 h of birth, or zidovudine 600 mg orally to the mother at onset of labour and 300 mg every 3 h until delivery, and 4 mg/kg orally twice daily to babies for 7 days after birth. We tested babies for HIV-1 infection at birth, 6-8 weeks, and 14-16 weeks by HIV-1 RNA PCR. We assessed HIV-1 transmission and HIV-1-free survival with Kaplan-Meier analysis. FINDINGS Nearly all babies (98.8%) were breastfed, and 95.6% were still breastfeeding at age 14-16 weeks. The estimated risks of HIV-1 transmission in the zidovudine and nevirapine groups were: 10.4% and 8.2% at birth (p=0.354); 21.3% and 11.9% by age 6-8 weeks (p=0.0027); and 25.1% and 13.1% by age 14-16 weeks (p=0.0006). The efficacy of nevirapine compared with zidovudine was 47% (95% CI 20-64) up to age 14-16 weeks. The two regimens were well tolerated and adverse events were similar in the two groups. INTERPRETATION Nevirapine lowered the risk of HIV-1 transmission during the first 14-16 weeks of life by nearly 50% in a breastfeeding population. This simple and inexpensive regimen could decrease mother-to-child HIV-1 transmission in less-developed countries.
