Health Insurance Status of Pregnant Women and the Likelihood of Receipt of Antenatal Screening for HIV in Sub-Saharan Africa. Curr HIV Res 2021; 19:248-259.

Abstract
BACKGROUND We investigated if initiating preventive care against HIV vertical transmission by antenatal HIV screening is independent of the patients' source of financial reimbursement for the care received in sub-Saharan Africa (SSA). METHODS Using information from the WHO's Global Health Expenditure Database and the Demographic Health Surveys Database for 27 sub-Saharan countries, we used Spearman's correlation and adjusted survey logistic regression to determine the potential relationship between enrollment in health insurance and the likelihood that expectant mothers would be offered antenatal HIV screening. RESULTS We found that expectant mothers covered by health insurance were more than twice as likely to be offered antenatal screening for HIV compared to the uninsured. The likelihood differed by the type of insurance plan the expectant mother carried. DISCUSSION Health insurance is more of a financial tool that this study finds to be necessary to boost the uptake of preventive and therapeutic HIV care in SSA. CONCLUSION The ensuing disparity in receiving proper care could hinder the goals of 90-90-90 and the forthcoming 95-95-95 plan in SSA.

Etowa J, Hannan J, Etowa EB, Babatunde S, Phillips JC. Determinants of infant feeding practices among Black mothers living with HIV: a multinomial logistic regression analysis. BMC Public Health 2021; 21:663. [PMID: 33827510 PMCID: PMC8025335 DOI: 10.1186/s12889-021-10675-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 03/22/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Infant feeding practices are imperative for babies' and mothers' health and emotional wellbeing. Although infant feeding may seem simple, the decisions surrounding it are complex and have far-reaching implications for women globally. This is an especially difficult concern among mothers living with HIV because breastfeeding can transmit HIV from mother to child. This is further complicated by cultural expectations in case of Black mothers living with HIV. This paper discusses determinants of infant feeding practices among Black mothers living with HIV who were on anti-retroviral therapy (ART) in two North American cites and one African city. METHODS A cross-sectional, multi-country survey using venue-based convenience sampling of Black mothers living with HIV was employed. The effective response rates were 89% (n = 89) in Ottawa, Canada; 67% (n = 201) in Miami, Florida, US; and 100% (n = 400) in Port Harcourt, Nigeria, equaling a total sample size of 690. Data were collected in Qualtrics and managed in Excel and SPSS. Multinomial logistic regression analyses were used to determine the factors influencing the mothers' infant feeding practices (Exclusive Formula Feeding [EFF] = 1; Mixed Feeding [MF] = 2; and Exclusive Breastfeeding [EBF while on ART] =3). RESULTS The results highlight socio-demographics, EFF determinants, and EBF determinants. The statistically significant determinants of infant feeding practices included national guideline on infant feeding, cultural beliefs and practices, healthcare systems, healthcare personnel, infant feeding attitudes, social support, and perceived stress. Mothers' mean ages were Ottawa (36.6 ± 6.4), Miami (32.4 ± 5.8), and Port Harcourt (34.7 ± 5.7). All sampled women gave birth to least one infant after their HIV diagnoses. Statistically significant (p < .05) determinants of EFF relative to MF were the national guideline of EFF (relative risk [RR] = 218.19), cultural beliefs (RR = .15), received healthcare (RR = 21.17), received healthcare through a nurse/midwife (RR = 3.1), and perceived stress (RR = .9). Statistically significant determinants of EBF relative to MF were received healthcare (RR = 20.26), received healthcare through a nurse/midwife (RR = 2.31), functional social support (RR = 1.07), and perceived stress (RR = .9). CONCLUSION While cultural beliefs and perceived stress favoured MF over EFF, advice of healthcare workers, and the care received from a nurse/midwife improved EFF over MF. Also while the mothers' perceived stress favoured MF over EBF, advice of their nurses or midwife and the social support improved EBF over MF. The providers advice was congruent with WHO and national guidelines for infant feeding among mothers living with HIV. These results have implications for nursing, healthcare practice, and policies on infant feeding practices for mothers living with HIV.

Abstract
OBJECTIVE To evaluate the association of type and timing of prophylactic maternal and infant antiretroviral regimen with time to first positive HIV-1 DNA PCR test, in nonbreastfed HIV-infected infants, from populations infected predominantly with HIV-1 non-B subtype virus. DESIGN Analysis of combined data on nonbreastfed HIV-infected infants from prospective cohorts in Botswana, Thailand, and the United Kingdom (N = 405). METHODS Parametric models appropriate for interval-censored outcomes estimated the time to first positive PCR according to maternal or infant antiretroviral regimen category and timing of maternal antiretroviral initiation, with adjustment for covariates. RESULTS Maternal antiretroviral regimens included: no antiretrovirals (n = 138), single-nucleoside analog reverse transcriptase inhibitor (n = 165), single-dose nevirapine with zidovudine (n = 66), and combination prophylaxis with 3 or more antiretrovirals [combination antiretroviral therapy (cART), n = 36]. Type of maternal/infant antiretroviral regimen and timing of maternal antiretroviral initiation were each significantly associated with time to first positive PCR (multivariate P < 0.0001). The probability of a positive test with no antiretrovirals compared with the other regimen/timing groups was significantly lower at 1 day after birth, but did not differ significantly after age 14 days. In a subgroup of 143 infants testing negative at birth, infant cART was significantly associated with longer time to first positive test (multivariate P = 0.04). CONCLUSION Time to first positive HIV-1 DNA PCR in HIV-1-infected nonbreastfed infants (non-B HIV subtype) may differ according to maternal/infant antiretroviral regimen and may be longer with infant cART, which may have implications for scheduling infant HIV PCR-diagnostic testing and confirming final infant HIV status.

Prevalence of Caesarean sections in Enugu, southeast Nigeria: Analysis of data from the Healthy Beginning Initiative. PLoS One 2017; 12:e0174369. [PMID: 28355302 PMCID: PMC5371319 DOI: 10.1371/journal.pone.0174369] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2016] [Accepted: 03/07/2017] [Indexed: 11/29/2022] Open
Abstract
Background In order to meet the Sustainable Development Goal to decrease maternal mortality, increased access to obstetric interventions such as Caesarean sections (CS) is of critical importance. As a result of women’s limited access to routine and emergency obstetric services in Nigeria, the country is a major contributor to the global burden of maternal mortality. In this analysis, we aim to establish rates of CS and determine socioeconomic or medical risk factors associated with having a CS in Enugu, southeast Nigeria. Methods Data for this study originated from the Healthy Beginning Initiative study. Participant characteristics were obtained from 2300 women at baseline via a semi-structured questionnaire. Only women between the ages of 17–45 who had singleton deliveries were retained for this analysis. Post-delivery questionnaires were used to ascertain mode-of-delivery. Crude and adjusted logistic regressions with Caesarean as the main outcome are presented. Results In this sample, 7.22% women had a CS. Compared to women who lived in an urban setting, those who lived in a rural setting had a significant reduction in the odds of having a CS (aOR: 0.58; 0.38–0.89). Significantly higher odds of having a CS were seen among those with high peripheral malaria parasitemia compared to those with low parasitemia (aOR: 1.54; 1.04–2.28). Conclusion This study revealed that contrary to the increasing trend in use of CS in low-income countries, women in this region of Nigeria had limited access to this intervention. Increasing age and socioeconomic proxies for income and access to care (e.g., having a tertiary-level education, full-time employment, and urban residence) were shown to be key determinants of access to CS. Further research is needed to ascertain the obstetric conditions under which women in this region receive CS, and to further elucidate the role of socioeconomic factors in accessing CS.

Abstract
Etiology, transmission and protection: Transmission of HIV, the causative agent of AIDS, occurs predominantly through bodily fluids. Factors that significantly alter the risk of HIV transmission include male circumcision, condom use, high viral load, and the presence of other sexually transmitted diseases. Pathology/Symptomatology: HIV infects preferentially CD4+ T lymphocytes, and Monocytes. Because of their central role in regulating the immune response, depletion of CD4+ T cells renders the infected individual incapable of adequately responding to microorganisms otherwise inconsequential. Epidemiology, incidence and prevalence: New HIV infections affect predominantly young heterosexual women and homosexual men. While the mortality rates of AIDS related causes have decreased globally in recent years due to the use of highly active antiretroviral therapy (HAART) treatment, a vaccine remains an elusive goal. Treatment and curability: For those afflicted HIV infection remains a serious illness. Nonetheless, the use of advanced therapeutics have transformed a dire scenario into a chronic condition with near average life spans. When to apply those remedies appears to be as important as the remedies themselves. The high rate of HIV replication and the ability to generate variants are central to the viral survival strategy and major barriers to be overcome. Molecular mechanisms of infection: In this review, we assemble new details on the molecular events from the attachment of the virus, to the assembly and release of the viral progeny. Yet, much remains to be learned as understanding of the molecular mechanisms used in viral replication and the measures engaged in the evasion of immune surveillance will be important to develop effective interventions to address the global HIV pandemic.

Abstract
Exclusive formula feeding, exclusive breastfeeding (EBF) with early weaning or the administration of antiretroviral therapy to lactating mothers and/or to breastfed newborns may lower postnatal HIV transmission. The aim of this study was to assess mothers' knowledge, attitudes and practice (KAP) on lactation in various real-life settings in sub-Saharan Africa. A questionnaire survey investigating KAP with regard to breastfeeding in pregnant women of unknown status (Questionnaire A, 16 items) or HIV-infected women (Questionnaire B, 37 items) was administered. Associations between newborn feeding KAP and demographic, socioeconomic, cultural and obstetric variables were investigated. From January 2007 to January 2008, 2112 pregnant women answered Questionnaire A in Burkina Faso, Cameroon, Chad, Tanzania, Uganda and Zambia. Most women (53.0%) declared EBF as the preferred feeding modality. The practice of strictly defined EBF in previous pregnancies was only 11.4%, which was inversely correlated with education and parity. Questionnaire B was answered by 225 HIV-infected pregnant women in Burkina Faso, Tanzania and Uganda. Knowledge about the lactation-associated risk was associated with previous dead children. Significant variability was observed among collaborating sites. The introduction of fluids other than maternal milk within 6 months of age is common practice in sub-Saharan Africa, requiring intensive health education efforts if strictly defined EBF is to be adopted to decrease HIV postnatal transmission. Significant variation in newborn feeding determinants was observed.

Abstract
Background The HIV epidemic in Russia has increasingly involved reproductive-aged women, which may increase perinatal HIV transmission. Methods Standard HIV case-reporting and enhanced perinatal HIV surveillance systems were used for prospective assessment of HIV-infected women giving birth in St. Petersburg, Russia, during 2004-2008. Trends in social, perinatal, and clinical factors influencing mother-to-child HIV transmission stratified by history of injection drug use, and rates of perinatal HIV transmission were assessed using two-sided χ2 or Cochran-Armitage tests. Results Among HIV-infected women who gave birth, the proportion of women who self-reported ever using injection drugs (IDUs) decreased from 62% in 2004 to 41% in 2008 (P < 0.0001). Programmatic improvements led to increased uptake of the following clinical services from 2004 to 2008 (all P < 0.01): initiation of antiretroviral prophylaxis at ≤28 weeks gestation (IDUs 44%-54%, non-IDUs 45%-72%), monitoring of immunologic (IDUs 48%-64%, non-IDUs 58%-80%) and virologic status (IDUs 8%-58%, non-IDUs 10%-75%), dual/triple antiretroviral prophylaxis (IDUs 9%-44%, non-IDUs 14%-59%). After initial increase from 5.3% (95% confidence interval [CI] 3.5%-7.8%) in 2004 to 8.5% (CI 6.1%-11.7%) in 2005 (P < 0.05), perinatal HIV transmission decreased to 5.3% (CI 3.4%-8.3%) in 2006, and 3.2% (CI 1.7%-5.8%) in 2007 (P for trend <0.05). However, the proportion of women without prenatal care and without HIV testing before labor and delivery remained unchanged. Conclusions Reduced proportion of IDUs and improved clinical services among HIV-infected women giving birth were accompanied by decreased perinatal HIV transmission, which can be further reduced by increasing outreach and HIV testing of women before and during pregnancy.

Abstract
Perinatal HIV prevention has been successful in developing countries but disparities in success between rich countries and poor countries have also been observed. Access to prevention of mother-to-child transmission (PMTCT) remains a challenge in many developing countries. In 2007, the Ministry of Health launched the Plan to Reduce the Vertical Transmission of HIV and Syphilis in Brazil to address this need. A cross-sectional study of children living in families affected by HIV was conducted in Ceara State, Northeast Brazil between June 2008 and January 2009 to explore socioeconomic effects of HIV status. Proportion of children with an HIV-positive test was calculated and stratified by age to estimate the impact of PMTCT programs. Chi-square test was employed to compare those proportions. Stata™10.0 software was used for the calculation. We interviewed 437 adults who were visiting the hospital for a consultation or to pickup medication who also had a child less than 13 years of age living with them. They also provided information about other household members (n=1789). Our study showed that children infected with HIV or who live in a household with one or both parents infected with HIV or dead from AIDS live in families of low social class and educational achievement. Seroprevalence is not lower in the cohort of those children 0-2 as compared to 3-4 and 5-12 years of age. Even in Brazil, with its successful PMTCT program overall, there are great disparities among sites. Data from the sites reported here are equivalent to many poor areas in sub-Saharan Africa. This argues that global concern for targeting areas most affected by the epidemic must consider areas within some of the most prosperous countries in the world.

Mother-to-infant transmission of simian immunodeficiency virus is rare in sooty mangabeys and is associated with low viremia. J Virol 2011; 85:5757-63.

Abstract
Mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) occurs in utero, intrapartum, and through breastfeeding, with a cumulative rate of transmission of 35 to 40%. As a result, ∼ 400,000 children become infected each year. Little is known about mother-to-infant transmission (MTIT) during natural simian immunodeficiency virus (SIV) infection of sooty mangabeys (SMs) that typically is nonpathogenic despite high viral loads. In this study, we retrospectively investigated the rates of MTIT in a large colony of naturally SIV-infected SMs using serological (anti-SIV antibody by enzyme-linked immunosorbent assay [ELISA] and Western blot analysis) and virological (SIV(smm) real-time reverse transcription-PCR) methods. We examined 161 SM infants born to SIV-infected mothers and found that 150 (93.2%) were infected by non-MTIT (n = 120) or remained uninfected (n = 30). The remaining 11 SM infants (6.8%) were defined as acquiring SIV by presumptive MTIT based on (i) the presence of anti-SIV antibodies without seroreversion and (ii) a viral load of >500 copies/ml of serum in the first year of life. SM infants infected with SIV by presumptive MTIT did not show any increased morbidity or mortality, indicating that the infection is nonpathogenic even when acquired early in life. Interestingly, viral loads of SIV-infected SM infants with presumptive MTIT were 2-log lower than those of SIV-infected adult SMs living in the same colony (i.e., ∼ 1,000 and 100,000 copies/ml, respectively). These results indicate that MTIT is substantially less frequent in naturally SIV-infected SMs than in HIV-1-infected humans and results in nonpathogenic infection associated with low SIV viremia. Evolutionary pressure to reduce MTIT may have contributed to the restriction of SIV pathogenesis in natural hosts.

Abstract
BACKGROUND Early HIV infant diagnosis and treatment have been shown to dramatically improve survival in infants. Despite these findings, infants accessing HIV diagnosis and treatment remain low in Uganda. We describe the antiretroviral (ARV) drugs given in the Mulago Hospital prevention of mother-to-child transmission (PMTCT) program from January 2007 to May 2009 and its impact on early infant HIV infection rates. METHODS Pregnant women identified as HIV infected in the Mulago antenatal clinics received one of the following regimens: short-course ARV prophylaxis plus single-dose nevirapine (sdNVP) in labor, highly active antiretroviral therapy (HAART), or sdNVP if they presented in labor. Infants received sdNVP and zidovudine (ZDV) for 1 week. Infants HIV diagnosis was done from 6 weeks after delivery. RESULTS 62.3% of HIV-infected women received combination ARVs, including HAART. Early infection rates were highest among infants with no maternal ARV [36.4; 95% confidence interval (CI): 17.2 to 59.3] or only sdNVP (11.2; 95% CI: 8.1 to 14.8). Similar rates were observed for the group that took short-course ARVs, ZDV/sdNVP (4.6; 95% CI: 3.2 to 6.4), and ZDV/lamivudine/sdNVP (4.9; 95% CI: 3.1 to 7.2) and lowest rates for those that took HAART (1.7: 95% CI: 0.8 to 2.8). Overall infection rate was 5.0% (95% CI: 4.1 to 5.9). CONCLUSIONS Findings indicate low rates of infant infection for mothers receiving combination ARVs. These findings demonstrate that provision of combination ARV for PMTCT is feasible and effective in busy referral hospital's PMTCT programs in resource-limited settings.
