Mother-to-child Transmission Of Human Immunodeficiency Virus Research Articles

Is breastfeeding an equipoise option in effectively treated HIV-infected mothers in a high-income setting?

Combined antiretroviral treatment (cART) has reduced mother-to-child transmission (MTCT) of the human immunodeficiency virus (HIV) to virtually zero in industrialised countries, where strictly bottle feeding is recommended for HIV-infected mothers, and to as low as 0.7% after 12 months in low-resource settings, where breastfeeding is strongly encouraged. Given the theoretically very low risk of transmission by breastfeeding with cART, and the advantages and benefits of breastfeeding, also in industrialised countries, the strong recommendation to HIV-infected mothers to refrain from breastfeeding in this setting may no longer be justified. We have evaluated risks of breastfeeding for HIV MTCT in the light of accessible cART, the general benefits of breastfeeding, and the women's autonomy to consent to any intervention. As we found no evidence in the literature of HIV MTCT via breastfeeding whilst on effective cART, we identified a situation of clinical equipoise. We propose how to proceed in Switzerland when HIV-infected women consider breastfeeding. We advocate a shared decision-making process and suggest a list of topics on which to provide unbiased information for the HIV-infected mother to enable her comprehensive understanding of one or the other decision. Although breastfeeding still should not be actively recommended in Switzerland, any HIV-infected mother, regardless of her geographical and cultural background, who decides to breastfeed should be supported by the best strategy to achieve optimal medical care for both herself and her child. This includes continuous support of cART adherence and regular maternal HIV plasma viral load monitoring.

Investigation of mother-to-child transmission of HIV in pregnancy and among HIV-exposed infants accessing care at a PMTCT clinic in southwest Nigeria

ABSTRACTBackground: Over 90% of infant acquired immunodeficiency syndrome (AIDS) cases have been through mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV). Consequent to this, prevention of mother-to-child transmission (PMTCT) programs have instituted as dual purposes for prevention of HIV transmission from mother to child and enrollment of infected pregnant women and their families into antiretroviral treatment (ART) program. However, there are still some breakthrough infections and challenges. Therefore, this study was designed to assess risk of HIV transmission among HIV-exposed infants on follow-up at a PMTCT clinic in an antiretroviral (ARV) referral health facility in southwest Nigeria.Methods: A cohort of 60 purposively recruited consenting pregnant women referred to PMTCT HIV clinic in Ibadan, southwest Nigeria were enrolled and followed up for 1 year (2015–2016). A well-structured epidemiological questionnaire was used to capture all relevant information. Data were then analyzed by SPSS version 21 (St. Louis, MO, USA), while bivariate and multivariate analyses were used to identify associations.Results: A total of 44 mothers and their infants were available for the analysis with an attrition rate of 26.7%. The mean age of mothers at enrollment to follow-up was 32.9 years (SD = 4.2 years). Two (4.5%, 95% CI: 7.2–12.3%) of the infants were HIV positive by DNA PCR test. There was no linear relationship between age of the mothers with CD4 count or viral load both before and after delivery but there was a significant positive relationship with year on ARV (r = 0.318, 95% CI: 0.024–0.562). Infants of rural dwelling mothers were at 3.39 (adjusted odds ratio (AOR) = 3.39, 95% CI: 1.32, 2.29) times higher risk of vertical HIV transmission compared to those of urban dwelling mothers. Infants delivered at home had 2.61(AOR = 2.61, 95% CI: 1.59, 7.91) times higher risk of MTCT compared to those delivered at health institution. Mixed feeding was also another important predictor in which the risk of MTCT was about two (AOR = 2.21, 95% CI: 0.68, 9.97) times higher compared to exclusive breastfeeding.Conclusions: There was a high risk of MTCT of HIV among exposed infants on follow-up at the PMTCT clinic of Adeoyo Maternity Teaching referral hospital. Our findings will assist health policy makers in providing important information capable of enhancing assurance HIV control in such population and in raising the standard of PMTCT program in Nigeria.

Mother-to-child transmission of HIV in Australia and other high-income countries: Trends in perinatal exposure, demography and uptake of prevention strategies.

Virtual elimination of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) is a global target. A review of the literature was conducted using medical databases and health department websites to examine the current trends related to perinatal HIV exposure and MTCT in Australia in comparison with other high-income countries (HICs). The review discusses the uptake of prevention strategies and barriers that impede MTCT prevention. The literature suggests an increase in the numbers of HIV-exposed deliveries, but a marked decline in the rates of MTCT within HICs. MTCT remains high when the mother's HIV infection is diagnosed late or postpartum. Data supports increasing trends of perinatal HIV exposure in migrant populations from low- and middle-income countries (particularly African women). Increased uptake and earlier initiation of antiretroviral therapy (ART) was associated with overall MTCT decline. Caesarean section remains the main mode of delivery described; however, the numbers of planned vaginal deliveries are increasing over time. Heterogeneity of data periods and outcome measures within published literature made comparisons between countries difficult. Future development should focus on clear national guidelines and a potential national database for perinatal HIV, culturally appropriate service provision, and more evidence on acute infections in pregnancy and the effects that longer duration and increased uptake of ART has on the fetus and resistance to ART.

Challenges and successes in the implementation of option B+ to prevent mother-to-child transmission of HIV in southern Swaziland

BackgroundUniversal antiretroviral therapy (ART) for all pregnant/ breastfeeding women living with Human Immunodeficiency Virus (HIV), known as Prevention of mother-to child transmission of HIV (PMTCT) Option B+ (PMTCTB+), is being scaled up in most countries in Sub-Saharan Africa. In the transition to PMTCTB+, many countries face challenges with proper implementation of the HIV care cascade. We aimed to describe the feasibility of a PMTCTB+ approach in the public health sector in Swaziland.MethodsLifelong ART was offered to a cohort of HIV+ pregnant women aged ≥16 years at the first antenatal care (ANC1) visit in 9 public sector facilities, between 01/2013 and 06/2014. The study enrolment period was divided into 3 phases (early: 01–06/2013, mid: 07–12/2013 and late: 01–06/2014) to account for temporal trends. Kaplan-Meier estimates and Cox proportional-hazards regression models were applied for ART initiation and attrition analyses.ResultsOf 665 HIV+ pregnant women, 496 (74.6%) initiated ART. ART initiation increased in later study enrolment phases (mid: aHR: 1.41; later: aHR: 2.36), and decreased at CD4 ≥ 500 (aHR: 0.69). 52.9% were retained in care at 24 months. Attrition was associated with ANC1 in the third trimester (aHR: 2.37), attending a secondary care facility (aHR: 1.98) and ART initiation during later enrolment phases (mid aHR: 1.48; late aHR: 1.67). Of 373 women eligible, 67.3% received a first VL. 223/251 (88.8%) were virologically suppressed (< 1000 copies/mL). Of 670 infants, 53.6% received an EID test, 320/359 had a test result recorded and of whom 7 (2.2%) were HIV+.ConclusionsPMTCTB+ was found to be feasible in this setting, with high rates of maternal viral suppression and low transmission to the infant. High treatment attrition, poor follow-up of mother-baby pairs and under-utilisation of VL and EID testing are important programmatic challenges.

Audit of prevention of mother-to-child transmission programme interventions in HIV-Exposed children at national hospital, Abuja, Nigeria

Ninety percentage of children acquire human immunodeficiency virus (HIV) infection in the form of Mother-to-child Transmission (MTCT). In the absence of interventions, transmission rates range from 15% to 45%. This can be reduced to below 5% with effective interventions. The last published national guideline (NG) on prevention of MTCT (PMTCT) was in 2010. Clinical audits are essential in improving the quality of care delivered to patients. The study objectives were to determine the rate of MTCT of HIV in exposed infants at a follow-up clinic between 2011 and 2014 and to determine the level of adherence to 2010 NG on the use of highly active antiretroviral therapy (HAART), polymerase chain reaction (PCR) testing, feeding options, antiretroviral (ARV) prophylaxis and the use of co-trimoxazole (CTZ). A retrospective review of data was done over 4 years. The population consisted of babies delivered through PMTCT programme and those referred to the clinic from other centres. Data analysis was done using the Statistical Package for the Social Sciences (SPSS) version 21. Out of 699 babies enrolled, MTCT occurred in 22 babies (3.2%) and PCR testing was done in 445 babies (64.7%), most in the 1-2 months' age group. Breastfeeding was practiced in 402 (58.2%) babies, while about 88.0% of them received post-exposure ARV prophylaxis (PEP). CTZ prophylaxis was offered to only 226 (34.6%) babies. The regression model showed that maternal use of HAART and PEP for babies was independently associated with a reduction in transmission rate. The MTCT rate was 3.2%. There is a need to strengthen service provision to adhere to NG, especially on breastfeeding and CTZ prophylaxis.

Human Immunodeficiency Virus Antiretroviral Resistance and Transmission in Mother-Infant Pairs Enrolled in a Large Perinatal Study.

The presence of antiretroviral drug-associated resistance mutations (DRMs) may be particularly problematic in human immunodeficiency virus (HIV)-infected pregnant women as it can lead to mother-to-child transmission (MTCT) of resistant HIV strains. This study evaluated the prevalence and the effect of antiretroviral DRMs in previously untreated mother-infant pairs. A case-control design of 1:4 (1 transmitter to 4 nontransmitters) was utilized to evaluate DRMs as a predictor of HIV MTCT in specimens obtained from mother-infant pairs. ViroSeq HIV-1 genotyping was performed on mother-infant specimens to assess for clinically relevant DRMs. One hundred forty infants acquired HIV infection; of these, 123 mother-infant pairs (88%) had specimens successfully amplified using ViroSeq and assessed for drug resistance genotyping. Additionally, 483 of 560 (86%) women who did not transmit HIV to infants also had samples evaluated for DRMs. Sixty-three of 606 (10%) women had clinically relevant DRMs; 12 (2%) had DRMs against >1 drug class. Among 123 HIV-infected infants, 13 (11%) had clinically relevant DRMs, with 3 (2%) harboring DRMs against >1 drug class. In univariate and multivariate analyses, DRMs in mothers were not associated with increased HIV MTCT (adjusted odds ratio, 0.8 [95% confidence interval, .4-1.5]). Presence of DRMs in transmitting mothers was strongly associated with DRM presence in their infants (P < .001). Preexisting DRMs were common in untreated HIV-infected pregnant women, but did not increase the risk of HIV MTCT. However, if women with DRMs are not virologically suppressed, they may transmit resistant mutations, thus complicating infant management.

Fertility desire and utilization of family planning methods among HIV-positive women attending a tertiary hospital in a suburban setting in Northern Nigeria

Background: One of the pillars of prevention of Mother to child transmission (MTCT) of Human Immunodeficiency Virus (HIV) involves prevention of pregnancy or delaying pregnancy until when it is desired in HIV-positive women. This study aimed to assess fertility desire, utilization of family planning method, and predictors for use of contraception among women living with HIV. Materials and Methods: This was a descriptive cross-sectional study, carried out at the Federal Medical Centre Birnin Kudu, Jigawa state, Nigeria. Using an interviewer-administered questionnaire, the fertility desire, utilization, and predictors of use of modern contraceptive methods was assessed among 330 HIV-positive women attending the hospital specialist clinic. Data was analyzed using SPSS. Results: Majority (n = 250; 75.8%) of the respondents desired to have more children, out of which 100 (40%) desired to have more than 6 children each while 80 women (24.2%) no longer wanted more children. Sixty-eight (20.6%) respondents had a change in fertility intention since diagnosed as HIV positive. The use of family planning methods was significantly associated with having formal education, being married, and being of the Christian faith (P Conclusion: Women living with HIV have different reproductive intentions with majority desirous of childbearing, hence they should be supported either to space their births or limit child bearing to reduce the risk of MTCT of HIV.

FACTORS THAT AFFECT MOTHER-TO-CHILD HIV TRANSMISSION AT A UNIVERSITY HOSPITAL IN SOUTHERN BRAZIL

Objective: To evaluate factors that may interfere in mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV). Method: A historical cohort study with a sample of 299 HIV-infected mothers and their newborns who delivered at the Obstetric Center of the Hospital de Clinicas de Porto Alegre, southern Brazil, from January 2010 to December 2014. Results: Of the 299 newborns of HIV-infected mothers, 3.7% (n = 11) were infected. Of those, 90.9% (n = 10) were born by cesarean section; 90.9% (n = 10) had ≥ 37 weeks; 54.6% (n = 6) received zidovudine starting within the first 4 hours after birth; and 45.4% (n = 5) received zidovudine and nevirapine. Four women whose newborns were infected with HIV had syphilis during pregnancy (36.4%). Poor adherence to highly active antiretroviral therapy (HAART) (p < 0.003), viral load ≥ 1000 copies/mL or ignored in the third trimester (p < 0.000), and CD4 count < 500 cells/mm 3 in the third trimester (p < 0.046) were significantly associated with an increased risk of MTCT. Conclusion: Lack of control of risk factors may contribute to unfavorable rates of MTCT of HIV.

Vaccine-Elicited Mucosal and Systemic Antibody Responses Are Associated with Reduced Simian Immunodeficiency Viremia in Infant Rhesus Macaques.

Despite significant progress in reducing peripartum mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) with antiretroviral therapy (ART), continued access to ART throughout the breastfeeding period is still a limiting factor, and breast milk exposure to HIV accounts for up to 44% of MTCT. As abstinence from breastfeeding is not recommended, alternative means are needed to prevent MTCT of HIV. We have previously shown that oral vaccination at birth with live attenuated Mycobacterium tuberculosis strains expressing simian immunodeficiency virus (SIV) genes safely induces persistent SIV-specific cellular and humoral immune responses both systemically and at the oral and intestinal mucosa. Here, we tested the ability of oral M. tuberculosis vaccine strains expressing SIV Env and Gag proteins, followed by systemic heterologous (MVA-SIV Env/Gag/Pol) boosting, to protect neonatal macaques against oral SIV challenge. While vaccination did not protect infant macaques against oral SIV acquisition, a subset of immunized animals had significantly lower peak viremia which inversely correlated with prechallenge SIV Env-specific salivary and intestinal IgA responses and higher-avidity SIV Env-specific IgG in plasma. These controller animals also maintained CD4(+) T cell populations better and showed reduced tissue pathology compared to noncontroller animals. We show that infants vaccinated at birth can develop vaccine-induced SIV-specific IgA and IgG antibodies and cellular immune responses within weeks of life. Our data further suggest that affinity maturation of vaccine-induced plasma antibodies and induction of mucosal IgA responses at potential SIV entry sites are associated with better control of viral replication, thereby likely reducing SIV morbidity. Despite significant progress in reducing peripartum MTCT of HIV with ART, continued access to ART throughout the breastfeeding period is still a limiting factor. Breast milk exposure to HIV accounts for up to 44% of MTCT. Alternative measures, in addition to ART, are needed to achieve the goal of an AIDS-free generation. Pediatric HIV vaccines constitute a core component of such efforts. The results of our pediatric vaccine study highlight the potential importance of vaccine-elicited mucosal Env-specific IgA responses in combination with high-avidity systemic Env-specific IgG in protection against oral SIV transmission and control of viral replication in infant macaques. The induction of potent mucosal IgA antibodies by our vaccine is remarkable considering the age-dependent development of mucosal IgA responses postbirth. A deeper understanding of postnatal immune development may inform the design of improved vaccine strategies to enhance systemic and mucosal SIV/HIV antibody responses.

Prevention and care of paediatric HIV infection in Ouagadougou, Burkina Faso: knowledge, attitudes and practices of the caregivers.

BackgroundThe paediatric Human Immunodeficiency Virus (HIV) epidemic still progresses because of operational challenges in implementing prevention of mother-to-child HIV transmission (PMCT) programs. We assessed the knowledge, attitudes and practices (KAP) of children’s caregivers regarding mother-to-child transmission (MTCT) of HIV, paediatric HIV infection, early infant diagnosis (EID), and paediatric antiretroviral treatment in Ouagadougou, Burkina Faso.MethodsWe undertook a qualitative survey in the four public hospitals managing HIV exposed or infected children, in Ouagadougou in 2011. A sociologist used a semi-structured questionnaire to interview caregivers of children less than 5 years old attending the paediatrics wards on their KAP. Study participants were divided into four groups as follows:those who did not yet know their children’s HIV infection status, those who were waiting for their children’s HIV test results, those who were waiting for antiretroviral treatment, and those who were already on antiretroviral treatment.ResultsA total of 37 caregivers were interviewed. The mean age was 32.5 years, and 29 (78 %) were mothers. Twenty seven (73 %) caregivers had primary or higher level of education, and 15 (40 %) described their occupation as “housewife”. Overall, 36 (97 %) of caregivers knew that the main route of HIV transmission for infants was through MTCT and 14 (38 %) specified that it occurred during pregnancy or delivery. Five percent thought that MTCT of HIV occurred during conception. PMTCT interventions could help prevent infant HIV infection according to 32 (87 %) caregivers. Thirty five percent of caregivers stated EID as a prevention strategy. Fifty-four percent of the participants believed that replacement feeding option would prevent MTCT of HIV; 24 (65 %) stated that they would prefer medical practitioners seek caregivers’ consent before carrying out any HIV-test for their child, and that caregivers’ consent was not compulsory before antiretroviral treatment. All caregivers thought that it was necessary to treat HIV-infected children, although they did not know what interventions could be done.ConclusionsThis study highlighted the low level of caregivers’ knowledge on paediatric HIV prevention and care in Ouagadougou. Awareness programs targeting caregivers need to be strengthened in order to improve the uptake of HIV early infant diagnosis and care.Electronic supplementary materialThe online version of this article (doi:10.1186/s12887-016-0569-y) contains supplementary material, which is available to authorized users.

Soluble CD14: An Independent Biomarker for the Risk of Mother-to-Child Transmission of HIV in a Setting of Preexposure and Postexposure Antiretroviral Prophylaxis.

Elevated soluble CD14 (sCD14) concentrations, a marker of monocyte activation, predicts adverse outcomes in human immunodeficiency virus (HIV)-infected adults. To examine the association of sCD14 concentrations with the risk of mother-to-child transmission (MTCT) of HIV, we nested a case-control study (49 pairs of infants and their HIV-infected mothers) within the Six-Week Extended-Dose Nevirapine trial. Median peripartum maternal log2 sCD14 concentration was higher among transmitters (defined as pairs in which maternally transmitted HIV infection occurred by 12 months of age) than nontransmitters (20.29 pg/mL vs 19.41 pg/mL; P = .005). There was an increased odds of MTCT for every log2 increase in maternal sCD14 concentration, after adjustment for maternal HIV load, CD4 count and cART exposure (adjusted odds ratio, 3.51; 95% confidence interval, 1.21-10.21). Maternal monocyte activation may adversely influence the risk of MTCT of HIV.

Vertical transmission rate of human immunodeficiency virus amid formula-fed infants in a resource-constrained tertiary hospital in Jos, Nigeria

Background: Human Immunodeficiency Virus (HIV) can be transmitted from infected mother to her baby. Objective: To assess transmission rate of HIV from seropositive mothers on highly active anti-retroviral therapy (HAART) to their formula-fed babies. Method: A cross-sectional study of 65 paired mothers on HAART and their formula-fed babies was carried out. Polymerase chain reaction-deoxyribonucleic acid (PCR-DNA) of the babies was done at six weeks of age. Epi info was used to analyse data. Results: Mean age of mothers was 30.26 ± 0.5 years. About 73.8% of the paired mothers were diagnosed with HIV before their current pregnancies and 69.2% initiated HAART before their current pregnancies. Duration of HAART use was between three months and two years. Modes of deliveries were caesarean section (15.4%) and vaginal route (84.6%). Only one (1.5%) of the babies was positive to PCR-DNA test at six weeks of age. There was no statistically significant association between the baby’s PCR-DNA at six weeks of age and the mode of delivery (OR-0.0047, CI-95%, Fisher Exact=0.8461) as well as between the time of initiation of HAART by the paired mothers and the paired baby’s PCR-DNA results (RR-0.9778, CI-95%, Fisher Exact=0.6923). Conclusions: Overall mother to child transmission (MTCT) rate in this study was 1.5%. Use of HAART for more than three months, irrespective of delivery route, is capable of significantly reducing MTCT of HIV even in resource-constrained settings.

Eliminating mother-to-child transmission of the human immunodeficiency virus in sub-Saharan Africa: The journey so far and what remains to be done.

This review was carried out to provide a comprehensive overview of efforts toward elimination of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) with respect to progress, challenges, and recommendations in 21 sub-Saharan African priority countries. We reviewed literature published from 2011 to April 2015 using 3 databases; PubMed, Scopus, and Web of Science, as well as the 2014 Global Plan Progress Report. A total of 39 studies were included. Between 2009 and 2013, there was a 43% reduction in new HIV infections, the final MTCT rate was reduced from 28% to 18%, and antiretroviral therapy (ART) coverage increased from 11% to 24%. Challenges included poor adherence to antiretroviral therapy, poor linkage between mother-child pairs and post-natal healthcare services low early infant diagnosis coverage, low pediatric ART coverage, and high unmet needs for contraceptive services. Future recommendations include identification of key barriers, health system strengthening, strengthening community involvement, and international collaboration. There has been significant progress toward eliminating MTCT of HIV, but more effort is still needed.

Prenatal Transmission of Syphilis and Human Immunodeficiency Virus in Brazil: Achieving Regional Targets for Elimination

Background. The Pan-American Health Organization has called for reducing (1) human immunodeficiency virus (HIV) mother-to-child transmission (MTCT) to ≤0.30 infections/1000 live births (LB), (2) HIV MTCT risk to ≤2.0%, and (3) congenital syphilis (CS) incidence to ≤0.50/1000 LB in the Americas by 2015. Methods. Using published Brazilian data in a mathematical model, we simulated a cohort of pregnant women from antenatal care (ANC) through birth. We investigated 2 scenarios: "current access" (89.1% receive one ANC syphilis test and 41.1% receive 2; 81.7% receive one ANC HIV test and 18.9% receive birth testing; if diagnosed, 81.0% are treated for syphilis and 87.5% are treated for HIV) and "ideal access" (95% of women undergo 2 HIV and syphilis screenings; 95% receive appropriate treatment). We conducted univariate and multivariate sensitivity analyses on key inputs. Results. With current access, we projected 2.95 CS cases/1000 LB, 0.29 HIV infections/1000 LB, 7.1% HIV MTCT risk, and 11.11 intrauterine fetal demises (IUFD)/1000 pregnancies, with significant regional variation. With ideal access, we projected improved outcomes: 1.00 CS cases/1000 LB, 0.10 HIV infections/1000 LB, HIV MTCT risk of 2.4%, and 10.65 IUFD/1000 pregnancies. Increased testing drove the greatest improvements. Even with ideal access, only HIV infections/1000 LB met elimination goals. Achieving all targets required testing and treatment >95% and reductions in prevalence and incidence of HIV and syphilis. Conclusions. Increasing access to care and HIV and syphilis antenatal testing will substantially reduce HIV and syphilis MTCT in Brazil. In addition, regionally tailored interventions reducing syphilis incidence and prevalence and supporting HIV treatment adherence are necessary to completely meet elimination goals.

Voluntary HIV Counseling and Testing Service Utilization among Pregnant Mothers in North West Ethiopia In 2014

Introduction: According to 2011 Ethiopian demographic health survey result, about 2.2% mothers were HIV (Human Immunodeficiency Virus) positive in Amhara regional state. HIV testing during pregnancy is the gateway for PMTCT (Prevention of Mother to Child Transmission) of HIV though its coverage was 72.0% to 82.5% in North-West Ethiopia. Objective: To assess VHCT (Voluntary HIV Counseling and Testing) service utilization and its determinants among pregnant mothers in North-West Ethiopia in 2014. Methods: A community based cross sectional study using both quantitative and qualitative research methods was conducted in Enemay woreda/district. Data was collected on systematically selected 386 pregnant mothers and 4 FGDs (Focus Group Discussion) on purposively selected pregnant mothers and their partners. A pre tested closed ended structured questionnaire and open ended questions were used to collect the quantitative and qualitative data respectively. Binary logistic regression was used for multivariate analysis of quantitative data. Result: Majority (81.6%) of participants were known transmission of HIV during pregnancy and about three quarter (76.2%) of them were tested for HIV in current pregnancy. In FGD, all participants were not agreed as HIV testing was important during pregnancy. The repeatedly cited reason for not up taking HIV testing during pregnancy was fear of stigma and discrimination if test result becomes positive. Pregnant mothers not knowledgeable about MTCT (Mother to Child Transmission) of HIV; have not intension for ARV Prophylaxisis, unable to bring their partner for test and mothers who believe VHCT was importance before marriage only were less likely utilizing VHCT service thus organizations working on VHCT should further enhance awareness creation by giving especial attention for these groups of pregnant mothers.

Lack of knowledge about mother-to-child HIV transmission prevention in pregnant women at Tijuana General Hospital, Baja California, Mexico.

The objective of this study was to identify determinants of human immunodeficiency virus (HIV) knowledge regarding mother-to-child transmission (MTCT) among pregnant women at Tijuana General Hospital, Baja California, Mexico. Between March and November 2003, patients from the prenatal care (n = 1294) and labor and delivery (L&D) units (n = 495) participated in a cross-sectional study to measure HIV knowledge. Less than one-third (30%) knew that HIV could be transmitted to a child during delivery, and 36% knew that HIV could be transmitted by breast-feeding. Only 27% knew that an MTCT could be prevented. Prenatal patients were more likely to know that MTCT was preventable (prenatal: 31% versus L&D 25%; P = .02). Logistic regression indicated that prenatal patients (odds ratio = 1.49, confidence interval 1.07-2.07) were more likely to know that HIV could be transmitted through breast-feeding. Overall, both groups had poor knowledge regarding MTCT of HIV.

Utilization of PMTCT services and associated factors among pregnant women attending antenatal clinics in Addis Ababa, Ethiopia.

BackgroundMother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) remains the major source of HIV infection in young children. Targeting pregnant women attending antenatal clinics provide a unique opportunity for implementing prevention of mother-to-child transmission (PMTCT) programmes against HIV infection of newborn babies. This study aimed to investigate factors associated with the acceptability and utilization of PMTCT of HIV.MethodsAn institution based cross-sectional study was conducted in April 2010 using exit interviews with 843 pregnant women attending antenatal care (ANC) clinics of 10 health centers and two hospitals in Addis Ababa, Ethiopia. Trained nurses administered structured questionnaires to collect data on socio-demographic characteristics, knowledge about MTCT, practice of HIV testing and satisfaction with the antenatal care services. Six focus group discussions among pregnant women and 22 in-depth interviews with service providers complemented the quantitative data.ResultsAbout 94% of the pregnant women visited the health facility for ANC check-up. Only 18% and 9% of respondents attended the facility for HIV counselling and testing (HCT) and receiving antiretroviral prophylaxis, respectively. About 90% knew that a mother with HIV can pass the virus to her child, and MTCT through breast milk was commonly cited by most women (72.4%) than transmission during pregnancy (49.7%) or delivery (49.5%). About 94% of them reported that they were tested for HIV in the current pregnancy and 60% replied that their partners were also tested for HIV. About 80% of the respondents reported adequacy of privacy and confidentiality during counseling (90.8% at hospitals and 78.6% at health centers), but 16% wished to have a different counselor. Absence of counselors, poor counselling, lack of awareness and knowledge about HCT, lack of interest and psychological unpreparedness were the main reasons cited for not undergoing HIV testing during the current pregnancy.ConclusionsHIV testing among ANC attendees and knowledge about MTCT of HIV was quite high. Efforts should be made to improve the quality and coverage of HCT services and mitigate the barriers preventing mothers from seeking HIV testing. Further research should be conducted to evaluate the uptake of antiretroviral prophylaxis among HIV-positive pregnant women attending ANC clinics.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2393-14-328) contains supplementary material, which is available to authorized users.

A survey of awareness and knowledge of mother-to-child transmission of HIV in pregnant women attending Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria

Objective: To determine the knowledge and awareness of Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) and mother-to-child transmission (MTCT) among women attending the antenatal clinic. Methods and Subjects: This was primarily a descriptive cross-sectional study carried out at the antenatal clinic of Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Nigeria from July 1st, 2010 to October 31st, 2010. Results: The age range of the respondents was 18 - 41 years, (mean 29 ± 5 years). One hundred and forty-nine (92.5%) were married. All the respondents interviewed were aware of HIV/AIDS and 93 (57.8%) had been aware of the disease for ≥5 years. The main sources of information were television 93 (57.8%), radio 77 (47.8%), health workers 53 (32.9%), friends, relatives and neighbors 41 (25.5%) and posters 34 (21.1%). Majority of the respondents identified sexual intercourse as a route of transmission of HIV. Sharing of sharp objects and blood transfusion were identified as routes of transmission by 99 (61.5%) and 82 (50.9%) respectively. One hundred and sixteen (72%) of the respondents knew an apparently healthy person could be living with HIV. Majority of the respondents 125 (77.6%) were aware that HIV can coexist with pregnancy and 120 (74.5%) were aware of MTCT of HIV. Vaginal delivery and breastfeeding were identified as routes of HIV transmission by 44 (27.3%) and 53 (32.9%) of respondents respectively. Delivery by caesarean section was identified as a method of prevention of MTCT by 25 (15.5%) respondents while as many as 48 (29.8%) respondents did not know any method of prevention of MTCT of HIV. Conclusion: This study demonstrates a low level of awareness of methods of prevention of MTCT of HIV among pregnant women booking for antenatal care in our center. Thus, there is the need for adequate counseling about HIV/AIDS and specific aspects of prevention of mother-to-child transmission in our antenatal clinics.

HIV mother-to-child transmission, mode of delivery, and duration of rupture of membranes: experience in the current era.

Objective. To evaluate whether the length of time of rupture of membranes (ROM) in optimally managed HIV-positive women on highly active antiretroviral therapy (HAART) with low viral loads (VL) is predictive of the risk of mother to child transmission (MTCT) of the human immunodeficiency virus (HIV). Study Methods. A retrospective case series of all HIV-positive women who delivered at two academic tertiary centers in Toronto, Canada from January 2000 to November 2010 was completed. Results. Two hundred and ten HIV-positive women with viral loads <1,000 copies/ml delivered during the study period. VL was undetectable (<50 copies/mL) for the majority of the women (167, 80%), and <1,000 copies/mL for all women. Mode of delivery was vaginal in 107 (51%) and cesarean in 103 (49%). The median length of time of ROM was 0.63 hours (range 0 to 77.87 hours) for the entire group and 2.56 hours (range 0 to 53.90 hours) for those who had a vaginal birth. Among women with undetectable VL, 90 (54%) had a vaginal birth and 77 (46%) had a cesarean birth. Among the women in this cohort there were no cases of MTCT of HIV. Conclusions. There was no association between duration of ROM or mode of delivery and MTCT in this cohort of 210 virally suppressed HIV-positive pregnant women.
