Abstract
BACKGROUND Despite global efforts to eliminate mother-to-child-transmission of HIV (MTCT), many children continue to become infected. We determined the prevalence of HIV among children with severe acute malnutrition (SAM) and that of their mothers, at admission to Mwanamugimu Nutrition Unit, Mulago Hospital, Uganda. We also assessed child factors associated with HIV-infection, and explored factors leading to HIV-infection among a subset of the mother-child dyads that tested positive. METHODOLOGY We conducted a cross-sectional evaluation within the REDMOTHIV (Reduce mortality in HIV) clinical trial that investigated strategies to reduce mortality among HIV-infected and HIV-exposed children admitted with SAM at the Nutrition Unit. From June 2021 to December 2022, we consecutively tested children aged 1 month to 5 years with SAM for HIV, and the mothers who were available, using rapid antibody testing upon admission to the unit. HIV-antibody positive children under 18 months of age had a confirmatory HIV-DNA PCR test done. In-depth interviews (IDIs) were conducted with mothers of HIV positive dyads, to explore the individual, relationship, social and structural factors associated with MTCT, until data saturation. Quantitative data was analyzed using descriptive statistics and logistic regression in STATAv14, while a content thematic approach was used to analyze qualitative data. RESULTS Of 797 children tested, 463(58.1%) were male and 630(79.1%) were ≤18months of age; 76 (9.5%) tested positive. Of 709 mothers, median (IQR) age 26 (22, 30) years, 188(26.5%) were HIV positive. Sixty six of the 188 mother-infant pairs with HIV exposure tested positive for HIV, an MTCT rate of 35.1% (66/188). Child age >18 months was marginally associated with HIV-infection (crude OR = 1.87,95% CI: 1.11-3.12, p-value = 0.02; adjusted OR = 1.72, 95% CI: 0.96, 3.09, p-value = 0.068). The IDIs from 16 mothers revealed associated factors with HIV transmission at multiple levels. Individual level factors: inadequate information regarding prevention of MTCT(PMTCT), limited perception of HIV risk, and fear of antiretroviral drugs (ARVs). Relationship level factors: lack of family support and unfaithfulness (infidelity) among sexual partners. Health facility level factors: negative attitude of health workers and missed opportunities for HIV testing. Community level factors: poverty and health service disruptions due to the COVID-19 pandemic. CONCLUSION In this era of universal antiretroviral therapy for PMTCT, a 10% HIV prevalence among severely malnourished children is substantially high. To eliminate vertical HIV transmission, more efforts are needed to address challenges mothers living with HIV face intrinsically and within their families, communities and at health facilities.

Abstract
Most children acquire human immunodeficiency virus (HIV) infection through mother-to-child transmission (MTCT). The risk of MTCT of HIV is generally 15%-40% without prophylaxis. MTCT has been responsible for approximately 370,000 infant HIV infections worldwide, with Nigeria accounting for 30% of cases. The study evaluated the effectiveness of a prevention program for MTCT of HIV infection by determining the rate of MTCT of HIV in infants who underwent the program by reviewing health records of mother-infant pairs at the Olabisi Onabanjo University Teaching Hospital. This cross-sectional study conducted over 12 years used medical records of 545 mother-infant pairs. The rate of MTCT of HIV infection was 2.9% in this study compared to 7.1% reported by the center earlier. The rate of MTCT of HIV infection was the lowest among mother-infant pairs who received prophylaxis. Ages at recruitment are a strong determinant of the risk of infection. Late usage of the MTCT prevention service is a risk for HIV infection in exposed infants.

Abstract
Objectives: Intimate partner violence (IPV) against pregnant or human immunodeficiency virus (HIV)-positive women have been previously studied. However, data on the impact of IPV on HIV-positive pregnant women have not been systematically synthesized. We performed a meta-analysis to explore this issue and provide evidence regarding IPV prevention and HIV infection control. Method: The PubMed, Web of Science, Cochrane Library, and Embase databases were systematically searched. Studies that quantitatively assessed the association between IPV and its adverse impact on HIV-positive women during pregnancy and post-partum were eligible for inclusion. Pooled odds ratios (ORs) were calculated. Findings: Eight studies were identified to meet our eligibility criteria. The adverse impacts of IPV against HIV-positive pregnant women mainly included nonadherence to maternal antiretroviral treatment during pregnancy, nondisclosure of HIV-positive status to male partners, nonadherence to infant antiretroviral prophylaxis, and antenatal depression. IPV caused a 180% and 145% increase in the odds of antenatal depression and nonadherence to infant antiretroviral prophylaxis, respectively, among HIV-positive women, compared to the odds of their IPV-free counterparts [OR = 2.80, 95% confidence interval (CI): 1.66-4.74; OR = 2.45, 95% CI: 1.40-4.27]. Conclusion: Limited evidence has suggested that IPV against HIV-positive pregnant women caused maternal depression during pregnancy and led to the possible failure of HIV prophylaxis adherence in infants. Interventions to address IPV may ultimately reduce the risk of depression-related adverse birth outcomes and vertical transmission in infants exposed to maternal HIV. Prevention and control against IPV should be developed for HIV-positive pregnant women.

Abstract
BACKGROUND This study aimed to evaluate the implementation of the prevention of mother-to-child transmission (PMTCT) of the HIV-PMTCT program in Kermanshah, west of Iran, from 2014 to 2021. METHODS The data of all HIV-infected mothers and their infants who were monitored by the Kermanshah behavioral diseases counseling center was extracted and recorded in a checklist. RESULTS Out of 95 included infant, 45 (47.4%) were girls and 50 (52.6%) were boys. The mothers were mostly infected with HIV via their infected spouse. The pregnancies of 77 cases (82.1%) were in accordance with the national guideline. The average length of treatment for this group was 185 days. Of the 18 mothers who did not receive treatment, nine were diagnosed during childbirth and nine had no available information. All infants born from infected mothers underwent after-birth-antiretroviral prophylaxis, and all remained healthy. There was no statistically significant relationship between the birth weight and height of neonates with maternal age, maternal last viral load, disease stage, education, and maternal CD4 levels. Only a statistically significant relationship was observed between the duration of treatment and the infants' weight. CONCLUSION The results suggest the feasibility and effectiveness of the PMTCT program for HIV-positive mothers in Kermanshah. It seems that if pregnant HIV-positive women are diagnosed early and covered by a good prevention program on time, the risk of HIV to their babies will be reduced, significantly.

PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0001218. [PMID: 36963073 PMCID: PMC10021727 DOI: 10.1371/journal.pgph.0001218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 12/28/2022] [Indexed: 03/14/2023]
Abstract
Option B+ approach for prevention of mother-to-child transmission (PMTCT) has demonstrated the potential to eliminate pediatric HIV infections. Its success depends on early infant diagnosis (EID) of HIV among the exposed infants within the first 6 weeks, and a subsequent confirmatory HIV test within 18 months. However, most mothers enrolling in option B+ in Tanzania do not come for such confirmatory tests. We examined factors associated with the turning-up of mother-baby pairs on the PMTCT program for a confirmatory HIV testing 18 months post-delivery in Tanzania. This study utilized longitudinal data collected between 2015 and 2017, from 751 mother-baby pairs enrolled in the PMTCT-option B+ approach in 79 health facilities from the 12 regions of Tanzania-mainland. Only 44.2% of 751 mother-baby records observed received the HIV confirmatory test by the 18th month. Mothers aged 25 years or above (adults' mothers) were 1.44 more likely to turn up for confirmatory HIV testing than young mothers; mothers with partners tested for HIV were 1.74 more likely to have confirmatory HIV testing compared with partners not tested for HIV. Newly diagnosed HIV-positive mothers were 28% less likely to bring their babies for a confirmatory HIV-testing compared to known HIV-positive mothers. Mothers with treatment supporters were 1.58 more likely to receive confirmatory HIV-testing compared to mothers without one. Mother-baby pairs who collected DBS-PCR-1 were 3.61 more likely to have confirmatory HIV-testing than those who didn't collect DBS-PCR-1. In conclusion, the confirmatory HIV testing within 18 months among mother-baby pairs enrolled in the Option B+ approach is still low in Tanzania. This is associated with low maternal age, having a male partner not tested for HIV, lack of experience with HIV services, lack of treatment supporters, and failure to take the DBS-PCR-1 HIV test within the first two months post-delivery.

Abstract
BACKGROUND The mother-to-child transmission of HIV-1 (MTCT) remains on the major route of HIV-transmission among pediatric populations in Africa. Though a prevention of MTCT (PMTCT) high-priority country, data on the MTCT burdens in Cameroon remains fragmented. OBJECTIVE We sought to assess the pooled MTCT rate, its risk-factors, and to characterize viral reservoirs of infected-children in Cameroon. METHODS All relevant observational cohort and cross-sectional studies conducted in Cameroon were searched from PubMed, African Journals Online, Google scholar, ScienceDirect and academic medical education databases. Heterogeneity and publication bias were respectively assessed by the I2 statistic and the Egger/funnel plot test. Meta-analysis was performed using the random effects model. MTCT rate >5% was considered as "high". This review was registered in the Prospero database, CRD42021224497. RESULTS We included a total of 29 studies and analyzed 46 684 children born from HIV-positive mothers. The overall rate of MTCT was 7.00% (95% CI = 6.07-8.51). According to regions, the highest burden was in Adamaoua-region (17.51% [95% CI:14.21-21.07]) with only one study found. PMTCT option-B+ resulted in about 25% reduction of MTCT (8.97% [95% CI: 8.71-9.24] without option-B+ versus 2.88% [95% CI: 5.03-9.34] with option-B+). Regarding risk-factors, MTCT was significantly associated with the absence of PMTCT-interventions both in children (OR:5.40 [95% CI: 2.58-11.27]) and mothers (OR: 3.59 [95% CI: 2.15-5.99]). Regarding viral reservoirs, a pro-viral DNA mean of 3.34±1.05 log10/mL was observed among 5/57 children and archived HIV drug resistance mutations were identified in pro-viral DNA marker among 21/79 infected-children. CONCLUSION In spite of the dropdown in MTCT following option-B+ implementation, MTCT remains high in Cameroon, with substantial disparities across regions. Thus, in this era of option-B+, achieving MTCT elimination requires interventions in northern-Cameroon. The variation in pro-viral load in infected-children underlines the relevance of characterizing viral reservoirs for possible infection control in tropical settings.

Abstract
Background The prevention of mother-to-child transmission (PMTCT) is considered one of the most successful HIV prevention strategies in detecting and reducing HIV acquisition in utero or at birth. It is anticipated that with the increasing growth of digital technologies mobile phones can be utilized to enhance PMTCT services by improving provider-client interactions, expanding access to counseling services, and assisting in counteracting social and structural barriers to uptake of PMTCT services. Understanding the subjective experiences of women accessing PMTCT services in different settings has the potential to inform the development and promotion of such methods. This paper explores the perspectives of HIV-positive pregnant women attending maternal and neonatal clinic services in Kisumu, Kenya. Methods Data are reported from in-depth interviews with women, following a longitudinal study investigating the impact of a structured, counselor-delivered, mobile phone counseling intervention to promote retention in care and adherence to ARV prophylaxis/treatment, for HIV-positive pregnant women. Thematic content analysis was conducted. Results Discussions indicated that mobile-phone counseling provided useful health-related information, enhanced agency, and assisted mothers access critical PMTCT services across the cascade of care. Similarly, mobile-phone counseling offered personalized one-to-one contact with trained health providers including facilitating discussion of personal issues that likely affect access to services. Findings also identified barriers to the uptake of services, including a lack of partner support, poor health, poverty, facility-related factors, and provider attitudes. Discussion Overall, findings show that mobile-phone counseling is feasible, acceptable, and can enhance access to PMTCT services by overcoming some of the individual and facility-level barriers. Although mobile-phone counseling has not been routinized in most health facilities, future work is needed to assess whether mobile-phone counseling can be scaled-up to aid in the effective use of HIV and PMTCT services, as well as improving other related outcomes for mother and child dyad.

Health care costs associated with clinic visits for prevention of mother-to-child transmission of HIV in Dar es Salaam, Tanzania. Medicine (Baltimore) 2021; 100:e27828. [PMID: 34797311 PMCID: PMC8601283 DOI: 10.1097/md.0000000000027828] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 10/28/2021] [Indexed: 01/05/2023] Open
Abstract
Early and appropriate antenatal care (ANC) is key for the effectiveness of prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV). We evaluated the importance of ANC visits and related service costs for women receiving option B+ to prevent mother-to-child transmission (MTCT) of HIV in Tanzania.A cost analysis from a health care sector perspective was conducted using routine data of 2224 pregnant women newly diagnosed with HIV who gave birth between August 2014 and May 2016 in Dar es Salaam, Tanzania. We evaluated risk of infant HIV infection at 12 weeks postnatally in relation to ANC visits (<4 vs ≥4 visits). Costs for service utilisation were estimated through empirical observations and the World Health Organisation Global Price Reporting Mechanism.Mean gestational age at first ANC visit was 22 (±7) weeks. The average number of ANC/prevention of MTCT visits among the 2224 pregnant women in our sample was 3.6 (95% confidence interval [CI] 3.6-3.7), and 57.3% made ≥4 visits. At 12 weeks postnatally, 2.7% (95% CI 2.2-3.6) of HIV exposed infants had been infected. The risk of MTCT decreased with the number of ANC visits: 4.8% (95% CI 3.6-6.4) if the mother had <4 visits, and 1.0% (95% CI 0.5-1.7) at ≥4. The adjusted MTCT rates decreased by 51% (odds ratio 0.49, 95% CI 0.31-0.77) for each additional ANC visit made. The potential cost-saving was 2.2 US$ per woman at ≥4 visits (84.8 US$) compared to <4 visits (87.0 US$), mainly due to less defaulter tracing.Most pregnant women living with HIV in Dar es Salaam initiated ANC late and >40% failed to adhere to the recommended minimum of 4 visits. Improved ANC attendance would likely lead to fewer HIV-infected infants and reduce both short and long-term health care costs due to less spending on defaulter tracing and future treatment costs for the children.

Abstract
HIV-1 integrates its genome into the DNA of host cells. Consequently, HIV-1 genomes are copied with the host cell DNA during cellular division. Little is known about the emergence and persistence of human immunodeficiency virus (HIV)-infected T-cell clones in perinatally infected children. We analyzed peripheral blood mononuclear cells (PBMCs) for clonal expansion in 11 children who initiated antiretroviral therapy (ART) between 1.8 and 17.4 months of age and with viremia suppressed for 6 to 9 years. We obtained 8,662 HIV type 1 (HIV-1) integration sites from pre-ART samples and 1,861 sites from on-ART samples. Expanded clones of infected cells were detected pre-ART in 10/11 children. In 8 children, infected cell clones detected pre-ART persisted for 6 to 9 years on ART. A comparison of integration sites in the samples obtained on ART with healthy donor PBMCs infected ex vivo showed selection for cells with proviruses integrated in BACH2 and STAT5B. Our analyses indicate that, despite marked differences in T-cell composition and dynamics between children and adults, HIV-infected cell clones are established early in children, persist for up to 9 years on ART, and can be driven by proviral integration in proto-oncogenes.

Abstract
Despite the goal of eliminating new human immunodeficiency virus (HIV) infections in children, mother-to-child transmission is still common in resource-poor countries. The aims of this study were to assess the occurrence of mother-to-child transmission of HIV (MTCT) by age 18 months, risk factors for transmission, and the implementation of the national prevention of MTCT (PMTCT) program in a rural hospital in Tanzania. Data were collated from various medical registers and records. We included 172 children and 167 HIV-infected mothers. Among 88 children (51%) with adequate information, 9 (10.2%) were infected. Increased risk of MTCT was associated with late testing of the child (>2 months) [OR = 9.5 (95% CI: 1.8–49.4)], absence of antiretroviral therapy during pregnancy [OR = 9.7 (95% CI: 2.1–46.1)], and maternal CD4 cell count <200 cells/mm3 [OR = 15.3 (95% CI: 2.1–111)]. We were unable to determine the occurrence of MTCT transmission in 84 children (49%). The results from this study highlight that there is an urgent need for enhanced efforts to improve follow-up of HIV-exposed children, to improve documentation in registries and records, and to facilitate ease of linkage between these.

The Frequency of HIV-1 Infection in Iranian Children and Determination of the Transmitted Drug Resistance in Treatment-Naïve Children. Curr HIV Res 2021; 17:397-407. [PMID: 31702525 DOI: 10.2174/1570162x17666191106111211] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 10/23/2019] [Accepted: 10/31/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND The advent of resistance-associated mutations in HIV-1 is a barrier to the success of the ARTs. OBJECTIVE In this study, the abundance of HIV-1 infection in Iranian children, and also detection of the TDR in naïve HIV-1 infected pediatric (under 12 years old) were evaluated. MATERIALS From June 2014 to January 2019, a total of 544 consecutive treatment-naïve HIV-1- infected individuals enrolled in this study. After RNA extraction, amplification, and sequencing of the HIV-1 pol gene, the DRM and phylogenetic analysis were successfully performed on the plasma specimens of the ART-naïve HIV-1-infected-children under 12 years old. The DRMs were recognized using the Stanford HIV Drug Resistance Database. RESULTS Out of the 544 evaluated treatment-naïve HIV-1-infected individuals, 15 (2.8%) cases were children under 12 years old. The phylogenetic analyses of the amplified region of pol gene indicated that all of the 15 HIV-1-infected pediatric patients were infected by CRF35_AD, and a total of 13.3% (2/15) of these children were infected with HIV-1 variants with SDRMs (one child harbored two related SDRMs [D67N, V179F], and another child had three related SDRMs [M184V, T215F, and K103N]), according to the last algorithm of the WHO. No PIs-related SDRMs were observed in HIV-1-infected children. CONCLUSION The current study demonstrated that a total of 13.3% of treatment-naïve HIV-1-infected Iranian pediatrics (under 12 years old) were infected with HIV-1 variants with SDRMs. Therefore, it seems that screening to recognize resistance-associated mutations before the initiation of ARTs among Iranian children is essential for favorable medication efficacy and dependable prognosis.

Abstract
Typical enteropathogenic Escherichia coli (tEPEC) infection is a major cause of diarrhoea and contributor to mortality in children <5 years old in developing countries. Data were analysed from the Global Enteric Multicenter Study examining children <5 years old seeking care for moderate-to-severe diarrhoea (MSD) in Kenya. Stool specimens were tested for enteric pathogens, including by multiplex polymerase chain reaction for gene targets of tEPEC. Demographic, clinical and anthropometric data were collected at enrolment and ~60-days later; multivariable logistic regressions were constructed. Of 1778 MSD cases enrolled from 2008 to 2012, 135 (7.6%) children tested positive for tEPEC. In a case-to-case comparison among MSD cases, tEPEC was independently associated with presentation at enrolment with a loss of skin turgor (adjusted odds ratio (aOR) 2.08, 95% confidence interval (CI) 1.37–3.17), and convulsions (aOR 2.83, 95% CI 1.12–7.14). At follow-up, infants with tEPEC compared to those without were associated with being underweight (OR 2.2, 95% CI 1.3–3.6) and wasted (OR 2.5, 95% CI 1.3–4.6). Among MSD cases, tEPEC was associated with mortality (aOR 2.85, 95% CI 1.47–5.55). This study suggests that tEPEC contributes to morbidity and mortality in children. Interventions aimed at defining and reducing the burden of tEPEC and its sequelae should be urgently investigated, prioritised and implemented.

Abstract
Objective To characterize human immunodeficiency virus (HIV)-positive infants among HIV-exposed infants (HEIs) in Nairobi County for public health action. Methods We conducted a retrospective review of records of HEIs' HIV polymerase chain reaction (PCR) results in Nairobi County in 2015, excluding confirmatory PCR-positive results. HIV-exposed infant registry data were entered into Microsoft Excel and descriptive and associative statistics were calculated with OpenEpi software. Results A total of 5802 HEI records were analyzed, with a median age of 4.5 (interquartile range, 8.5) months; 342 (5.9%) tested positive, 51% were female, and 4420 (76.2%) were seen at maternal and child health clinics. Standard highly active antiretroviral therapy intervention was given to 184 (60.3%) of the mothers of exposed infants, and 178 (53%) of the HIV-positive infants received active antiretroviral therapy. A total of 3464 (59.7%) HEIs had PCR done within the first 2 months, and 119 (3.4%) tested positive. The average turnaround time for PCR samples was 28 ± 22 days, and a total of 191 (3.3%) HIV-positive HEIs were exclusively breastfed for the first 6 months of life. Conclusion The recorded mother-to-child transmission (MTCT) rate of 5.9% in Nairobi County is lower than the 2015 national rate, which suggests the Nairobi prevention of mother-to-child transmission efforts are moderately effective. However, results from this study show that Kenya will struggle to meet the MTCT 2020 target rate of <5%.

Abstract
Background The number of women living with the human immunodeficiency virus (WLHIV) in Muslim-majority countries has increased significantly in the last decade. These women are often marginalized and face insecure sexual and reproductive health (SRH) needs and rights. However, little is known about the multi-faceted factors influencing these women’s fertility, contraceptive, and perinatal decisions and sexual life. This systematic mixed studies review aimed to synthesize the empirical evidence on social, cultural, and structural factors influencing the SRH of WLHIV in Muslim-majority countries. Methods This review provides a synthesis of quantitative, qualitative and mixed-method research findings searched from PubMed, EMBASE, Scopus, CINAHL and Cochrane databases. We screened 3452 SRH studies involving WLHIV. The studies, published in English between 2008 and 2017, were from 20 Muslim-majority countries with increased numbers of WLHIV. The quality of eligible studies was appraised using a mixed-methods appraisal tool (MMAT) version 2011. Findings were thematically analysed by a hybrid deductive-inductive approach. Two independent reviewers were involved in the study selection, data extraction, quality appraisal, and data synthesis. Results We included 13 SRH-related studies involving 1748 WLHIV in eight Muslim-majority countries. Most of these studies explored fertility desire and sexual health, while only a small proportion related to contraceptive use and the perinatal-care experience. We identified that WLHIV faced neglect of their SRH rights. These rights were predominantly affected by the socio-cultural, religious and health-services context of the women’s lives, which directed them to unsafe sex practices and stressful perinatal experiences. Conclusions This study points to the need for SRH laws, policies, and interventions which stop WLHIV experiencing SRH discrimination violence and achieving their SRH rights.

Abstract
RATIONALE Early Infant Diagnosis (EID) is critical to timely identification of HIV and rapid treatment initiation for infants found to be infected. Completing the EID cascade involves a series of age-specific tests between birth and 18 months and can be challenging for mother- infant pairs in low-resource settings. Even prior to recent increases in Kenya's testing recommendations, approximately 22% of mother-infant pairs enrolled in EID were lost to follow-up. As EID cascades become increasingly complex, identifying strategies to maximize retention becomes even more essential. Despite ongoing health system improvements, we still lack a framework for understanding the individual-level, psychosocial processes underlying EID completion-insight that could be essential for shaping strategies to support patients and close gaps in retention. OBJECTIVE Our objective was to explain individual-level processes that lead to EID completion among mothers who successfully completed the EID cascade. METHODS Using qualitative methods informed by grounded theory, we conducted 65 interviews with Kenyan mothers who completed EID. RESULTS We identified three themes related to completion: (1) Negative motivation, from the consequences of infant infection, fear of postnatal transmission, and burden of maternal failure; (2) Positive motivation, from achieving a final goal, responding to provider support, and maximizing infant health; and (3) Overcoming challenges, through resolve/resiliency, planning/privatizing and rejecting stigma/leveraging support. CONCLUSION Overall, the EID cascade served as a framing process for women to secure an identity as a good mother. Successful EID completion was the product of a strong motivational foundation channeled into strategies to surmount persistent challenges. Participant accounts of overcoming challenges highlight their resiliency as well as the outstanding need to address financial, logistical, and social barriers to care. Future EID programs may capitalize on these findings by affirming patients' quest for identity control, leveraging positive motivators, and expanding peer support structures to help mothers feel connected throughout the cascade.

Abstract
HIV-exposed uninfected (HEU) infants are disproportionately at a higher risk of morbidity and mortality, as compared to HIV-unexposed uninfected (HUU) infants. Here, we used transcriptional profiling of peripheral blood mononuclear cells to determine immunological signatures of in utero HIV exposure. We identified 262 differentially expressed genes (DEGs) in HEU compared to HUU infants. Weighted gene co-expression network analysis (WGCNA) identified six modules that had significant associations with clinical traits. Functional enrichment analysis on both DEGs and the six significantly associated modules revealed an enrichment of G-protein coupled receptors and the immune system, specifically affecting neutrophil function and antibacterial responses. Additionally, malaria pathogenicity genes (thrombospondin 1-(THBS 1), interleukin 6 (IL6), and arginine decarboxylase 2 (ADC2)) were down-regulated. Of interest, the down-regulated immunity genes were positively correlated to the expression of epigenetic factors of the histone family and high-mobility group protein B2 (HMGB2), suggesting their role in the dysregulation of the HEU transcriptional landscape. Overall, we show that genes primarily associated with neutrophil mediated immunity were repressed in the HEU infants. Our results suggest that this could be a contributing factor to the increased susceptibility to bacterial infections associated with higher morbidity and mortality commonly reported in HEU infants.

Abstract
Early infant diagnosis (EID) involves age-specific tracking and testing of HIV-exposed infants during the first 18 months of life and rapid initiation of life-saving treatment for those infected. In Kenya, pre-2013 data estimate EID lost to follow-up (LTFU) at 39-65%, yet no study has documented LTFU rates and predictors throughout the EID cascade since Option B+ fundamentally changed services by placing all HIV-positive expectant mothers on lifelong treatment. Using an explanatory mixed-method design, we assessed LTFU rates and predictors among 870 mother-infant dyads enrolled in EID in six urban/peri-urban Kenyan government hospitals. Mothers completed baseline surveys, and dyads were tracked through EID. We selected 12 baseline variables and modeled odds of LTFU at 9 and 18 months using mixed logistic regression. Qualitative interviews were conducted with 61 mothers to assess barriers and facilitators to completing EID. Thematically coded transcripts were used to interpret quantitative predictors of LTFU. By the 18-month test, 145 dyads (22%) were LTFU, with three-quarters of LTFU occurring between 9- and 18-month tests. Odds of LTFU at 18 months decreased by 10% for each additional year of maternal age and by 66% with HIV status disclosure. Qualitative data revealed how disclosure facilitated essential social support for EID completion and how older mothers attributed maturity and life experience to successful engagement in care. Findings suggest LTFU rates in Kenya have declined, but gaps remain in ensuring universal coverage. Efforts to improve retention should focus on increasing support for younger mothers and those who have not disclosed their HIV status.

Abstract
The Partnership for HIV-Free Survival (PHFS) was piloted in rural Kenya using a quality improvement approach to integrate nutrition with prevention of mother-to-child transmission (PMTCT) of HIV services. Data were collected in a preintervention baseline (January 2013 to August 2013) and 3 periods during implementation (September 2013 to June 2016). Integration of nutrition assessment, counseling, and support (NACS) in PMTCT and retention of mother-baby pairs (MBPs) in care showed significant increase over time: The MBPs receiving NACS increased from a baseline median of 15% to 88% (P ≤ .05), and the proportion of MBPs retained in active care increased from a baseline median of 19% to a median of 66% (P ≤ .01). Declines observed in the number of HIV-exposed infants who tested positive for HIV at 18 months were not statistically significant. The PHFS was successful in integrating NACS into PMTCT services and increasing retention of MBPs in care in Kenya.

Abstract
The vertical transmission of HIV, from mother to child remains one of the biggest challenges all over the world. This study evaluated the implementation and effectiveness of the prevention of mother to child HIV transmission (PMTCT) program from 2011 to 2017 in Suzhou. A total of 107 HIV positive women were enrolled in the program, of which 11 were diagnosed through premarital examination, and 96 women were diagnosed through prenatal examination. Among the 96 pregnant women, 67 gave birth to 68 live neonates. Only one infant was diagnosed HIV infected because the HIV positive mother did not enter the PMTCT program until delivery. The HIV prevalence in Suzhou city showed a low-level tendency. To increase the prenatal health utility and antiretroviral medication compliance of the migrant population in Suzhou, there are improvements to make in order to achieve the 90-90-90 targets.

Abstract
Male involvement in antenatal care has been shown to improve health outcomes for women and infants. However, little is known about how best to encourage male partners to support essential perinatal health activities. We explored men's perceptions of facilitators and barriers to involvement in antenatal care and HIV prevention including fears, hopes and challenges. Forty in-depth interviews were conducted with the male partners of HIV-positive and HIV-negative pregnant women in southwest Kenya. Most male partners believed engaging in pregnancy health-related activities was beneficial for keeping families healthy. However, thematic analysis revealed several obstacles that hindered participation. Poor couple relationship dynamics seemed negatively to influence male engagement. Some men were apprehensive that clinic staff might force them to test for HIV and disclose the results; if HIV-positive, men feared being labelled as 'victimisers' in situations of serodiscordancy, and described fears of abandonment by their wives. Some men avoided accompanying their wives, citing local culture as rationale for avoiding the 'effeminate' act of antenatal care attendance. Amidst these obstacles, some men chose to use their partners' HIV status as proxy for their own. Findings suggest that improving male engagement in essential maternal and child health-related activities will require addressing both structural and interpersonal barriers.

Abstract
Introduction to determine the predictors of mortality in infants in Siaya, western Kenya, ahead of novel tuberculosis (TB) vaccine trials in the same population. Methods in a study to determine tuberculosis incidence, 2900 infants aged 0-45 days, weighing ≥ 1700g were enrolled. Four monthly follow up visits were conducted for at least 12 months. HIV testing was done at six weeks of age. Free ancillary care was provided. Deaths were reported by parents, study staff and community workers. Cox proportional Hazard analysis was used to identify risk factors. The period of analysis commenced at six weeks old and was censored at 12 months of age. Results included in the analysis were 2528 infants with 2020 person years of follow up (pyo). There were 117 deaths (4.6 %). The post-neonatal mortality rate was 58 (95% CI: 48, 69) per 1000 pyo. In multivariate analysis, health facility births were protective against mortality (Hazard Ratio (HR) 0.54; 95% CI: 0.34, 0.84) and infant HIV infection at baseline was associated with increased mortality (HR 10.3; 95% CI: 6.40, 16.7). HIV uninfected infants born to HIV infected mothers had increased hazards of mortality (HR 1.73; 95% CI: 1.03, 2.90). Gender, weight at six weeks, maternal education and occupation were not significant predictors of mortality. Conclusion infant mortality was high and was associated with being born outside a health facility, maternal HIV infection and HIV infection of the infant. Measures to decrease mother to child transmission and other HIV control measures need to be strengthened further to see incremental reductions in infant mortality.

Abstract
OBJECTIVE We measured the effect of point-of-care (POC) early infant HIV testing on antiretroviral therapy initiation rates and retention in care among infants in Mozambique. DESIGN A cluster-randomized trial was conducted in 16 primary healthcare centres providing either on-site POC arm (n = 8) or referred laboratory [standard-of-care (SOC) arm; n = 8] infant HIV testing. METHODS The primary outcomes were the proportion of HIV-positive infants initiating antiretroviral therapy within 60 days of sample collection, and the proportion of HIV-positive infants who initiated antiretroviral therapy that were retained in care at 90 days of follow-up. RESULTS The proportion of HIV-positive infants initiating antiretroviral therapy within 60 days of sample collection was 89.7% (157 of 175) for the POC arm and 12.8% (13 of 102) for the SOC arm [relative risk (RR)(adj) 7.34; P < 0.001]. The proportion of HIV-positive infants who initiated antiretroviral therapy that were retained in care at 90 days of follow-up was 61.6% (101 of 164) for the POC arm and 42.9% (21 of 49) for the SOC arm [RR(adj) 1.40; P < 0.027]. The median time from sample collection to antiretroviral therapy initiation was less than 1 day (interquartile range: 0-1) for the POC arm and 127 days (44-154; P < 0.001) for the SOC arm. CONCLUSION POC infant HIV testing enabled clinics to more rapidly diagnose and provide treatment to HIV-infected infants. This reduced opportunities for pretreatment loss to follow-up and enabled a larger proportion of infants to receive test results and initiate antiretroviral therapy. The benefits of faster HIV diagnosis and antiretroviral treatment may also improve early retention in care.

Abstract
BACKGROUND The burden of mother-to-child transmission rate of HIV is high and risk factors are common in Ethiopia. This systematic review and meta-analysis intended to provide the pooled estimation of mother-to-child transmission rate and its risk factors in Ethiopia. METHODS We searched PubMed, Google Scholar, EMBASE and Web of Science electronic databases for all available references. We included observational studies including case-control, cohort, and cross-sectional studies. The search was further limited to studies conducted in Ethiopia and publish in English. Heterogeneity was checked using the I2 statistic. Egger's test and the funnel plot were used to assess publication bias. A meta-analysis using a weighted inverse variance random-effects model was performed. RESULTS A total of 18 studies with 6253 individuals were included in this systematic review and meta-analysis. Of these, 14 studies with 4624 individuals were used to estimate the prevalence. The estimated pooled prevalence of mother-to-child transmission of HIV was 11.4% (95% CI = 9.1-13.7). The pooled adjusted odds ratio (AOR) of mother-to-child transmission of HIV for the infants from rural area was 3.8 (95% CI = 1.4 to 6.3), infants delivered at home was 3.2 (95% CI = 1.2 to 5.2), infant didn't take antiretroviral prophylaxis was 5.8 (95% CI = 1.5 to 10.3), mother didn't take antiretroviral prophylaxis was 6.1 (95% CI = 2.5 to 9.6), mothers didn't receive PMTCT intervention was 5.1 (95% CI = 1.6, 8.6), and on mixed feeding was 4.3 (95% CI = 1.8 to 6.7). CONCLUSIONS This systematic review and meta-analysis showed that mother-to-child transmission rate of HIV was high in Ethiopia. Being from the rural residence, home delivery, not taking antiretroviral prophylaxis, the absence of PMTCT intervention, and mixed infant feeding practices increased the risk of HIV transmission. TRIAL REGISTRATION It is registered in the Prospero database: (PROSPERO 2017: CRD42017078232 ).

Abstract
Clinical monitoring of pediatric HIV treatment remains a major challenge in settings where drug resistance genotyping is not routinely available. As a result, our understanding of drug resistance, and its impact on subsequent therapeutic regimens available in these settings, remains limited. We investigate the prevalence and correlates of HIV-1 drug resistance among 94 participants of the Ethiopia Pediatric HIV Cohort failing first-line combination antiretroviral therapy (cART) using dried blood spot-based genotyping. Overall, 81% (73/90) of successfully genotyped participants harbored resistance mutations, including 69% (62/90) who harbored resistance to both Nucleoside Reverse Transcriptase Inhibitors (NRTIs) and Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs). Strikingly, 42% of resistant participants harbored resistance to all four NRTIs recommended for second-line use in this setting, meaning that there are effectively no remaining cART options for these children. Longer cART duration and prior regimen changes were significantly associated with detection of drug resistance mutations. Replicate genotyping increased the breadth of drug resistance detected in 34% of cases, and thus is recommended for consideration when typing from blood spots. Implementation of timely drug resistance testing and access to newer antiretrovirals and drug classes are urgently needed to guide clinical decision-making and improve outcomes for HIV-infected children on first-line cART in Ethiopia.

Abstract
Human immunodeficiency virus (HIV) infection is mostly spreading in developing countries. One of the most important pathways of HIV infection in these nations is the vertical route, from mother to infant. Therefore, this study evaluated the effectiveness of the prevention of mother-to-child transmission (PMTCT) program for HIV among Iranian neonates born to HIV-positive mothers. A total of 54 neonates born to HIV-1 positive mothers, all of whom were in a PMTCT program for HIV, as per the Iranian guidelines, were enrolled in this descriptive cross sectional study from March 2014 to July 2017. After RNA extraction of a plasma specimen, HIV-1 viral load was tested by an Artus HIV-1 RG RT-PCR Kit. Out of 54 evaluated neonates, 32 (59.3%) were male. The mean age of the HIV-infected mothers was 30.1 ± 5.4 (range: 19-47) years, and 36 (66.7%) of the mothers were in the age group 26-34 years. In the present study, it was found that none of the neonates whose mothers had previously entered PMTCT programs had HIV. 15 children were found who were born to HIV-positive mothers who had not entered the PMTCT program. Three of these children were infected with HIV (CRF35_AD), and none of them carried HIV-1 variants with SDRMs. The results of this study indicate that if HIV-positive pregnant women enter the PMTCT program for HIV, they can realistically hope to give birth to a non-infected child.

Abstract
BACKGROUND To synthesize and evaluate the impact of implementing post-2010 World Health Organization (WHO) prevention of mother-to-child transmission (PMTCT) guidelines on attainment of PMTCT targets. METHODS Retrospective and prospective cohort study designs that utilized routinely collected data with a focus on provision and utilization of the cascade of PMTCT services were included. The outcomes included the proportion of pregnant women who were tested during their antenatal clinic (ANC) visits; mother-to-child transmission (MTCT) rate; adherence; retention rate; and loss to follow-up (LTFU). RESULTS Of the 1210 references screened, 45 met the inclusion criteria. The studies originated from 14 countries in sub-Saharan Africa. The highest number of studies originated from Malawi (10) followed by Nigeria and South Africa with 7 studies each. More than half of the studies were on option A while the majority of option B+ studies were conducted in Malawi. These studies indicated a high uptake of human immunodeficiency virus (HIV) testing ranging from 75% in Nigeria to over 96% in Zimbabwe and South Africa. High proportions of CD4 count testing were reported in studies only from South Africa despite that in most of the countries CD4 testing was a prerequisite to access treatment. MTCT rate ranged from 1.1% to 15.1% and it was higher in studies where data were collected in the early days of the WHO 2010 PMTCT guidelines. During the postpartum period, adherence and retention rate decreased, and LTFU increased for both HIV-positive mothers and exposed infants. CONCLUSION Irrespective of which option was followed, uptake of antenatal HIV testing was high but there was a large drop off along later points in the PMTCT cascade. More research is needed on how to improve later components of the PMTCT cascade, especially of option B+ which is now the norm throughout sub-Saharan Africa.

Low mother-to-child HIV transmission rate but high loss-to-follow-up among mothers and babies in Mandalay, Myanmar; a cohort study. PLoS One 2017; 12:e0184426.

Abstract
Introduction Loss-to-follow-up (LTFU) throughout the Prevention of Mother-To-Child Transmission (PMTCT) cascade remains one of the major threats to the success of PMTCT programs. In this study, we aimed to determine the mother-to-child transmission rate in a programmatic setting and to determine factors associated with LTFU among enrolled mothers and unfavorable outcomes among HIV-exposed babies which includes being HIV positive, death and LTFU. Methods A retrospective cohort study reviewing routinely collected data in an Integrated HIV care program, Mandalay, Myanmar in June 2016.LTFU means mother/infant missing appointed visit for more than three months. Results Of 678 pregnant women enrolled in PMTCT program between March 2011 and June 2014, one stillbirth and 607 live births were recorded in this cohort. Of 457 HIV-exposed babies with HIV-test recorded at the end of the intervention, nine (2%) were HIV-positive. Pregnant women’s and exposed-babies’ LTFU rate was 7 per 1000 person-years, and 10 per 1000 person-years respectively. PMTCT option B protocol was found to be significantly associate with maternal LTFU [adjusted Hazard Ratio (aHR) 95% CI: 3.52 (1.38–8.96)] when compare to mothers receiving option B+/lifelong antiretroviral therapy (ART). Weight <2.5 Kg at enrolment, receiving mixed-feeding, vaginal delivery and option B PMTCT protocol were significantly associated with unfavorable outcomes among exposed babies [aHR(95% CI): 5.40 (1.66–17.53), 5.91(1.68–20.84), 2.27 (1.22–4.22) and 2.33 (1.16–4.69) respectively]. Conclusion Mother-to-child HIV transmission rate in this public hospital-based program was lower than the 5% national target, which indicates a successful PMTCT intervention. However, a high proportion of HIV-infected mothers and exposed babies LTFU was recorded. Lifelong ART provision to HIV-positive pregnant women was shown to reduce exposed babies’ LTFU, death and transmission rate (unfavorable outcomes) in this setting. Lessons learned from this program could be used to inform policy and practice in the country, while the programmatic challenge of LTFU should be urgently addressed.

Abstract
Objective: Factors associated with poor health in HIV-exposed-uninfected (HEU) infants are poorly defined. We describe the prevalence and correlates of cytomegalovirus (CMV) viraemia in HEU and HIV-unexposed-uninfected (HUU) infants, and quantify associations with anthropometric, haematological, and immunological outcomes. Design: Cross-sectional, including HEU and HUU infants from rural coastal Kenya. Methods: Infants aged 2–8 months were studied. The primary outcome was CMV viraemia and viral load, determined by quantitative PCR. Correlates were tested by logistic and linear regression; coefficients were used to describe associations between CMV viraemia and clinical/immunological parameters. Results: In total, 42 of 65 (64.6%) infants had CMV viraemia [median viral load, 3.0 (interquartile ranges: 2.7–3.5) log10 IU/ml]. Compared to community controls, HEU infants had six-fold increased odds of being viraemic (adjusted odds ratio 5.95 [95% confidence interval: 1.82–19.36], P = 0.003). Age, but not HEU/HUU status, was a strong correlate of CMV viral load (coefficient = −0.15, P = 0.009). CMV viral load associated negatively with weight-for-age (WAZ) Z-score (coefficient = −1.06, P = 0.008) and head circumference-for-age Z-score (coefficient = −1.47, P = 0.012) and positively with CD8+ T-cell coexpression of CD38/human leucocyte antigen DR (coefficient = 15.05, P = 0.003). Conclusion: The odds of having CMV viraemia was six-fold greater in HEU than HUU infants when adjusted for age. CMV viral load was associated with adverse growth and heightened CD8+ T-cell immune activation. Longitudinal assessments of the clinical effects of primary CMV infection and associated immunomodulation in early life in HEU and HUU populations are warranted.

[PMID: 28424189 PMCID: PMC5445677 DOI: 10.3945/ajcn.116.149815] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2016] [Accepted: 03/15/2017] [Indexed: 11/14/2022] Open
Abstract
Background: There is an increasing recognition of malnutrition among infants under 6 mo of age (U6M). Current diagnosis criteria use weight-for-length z scores (WLZs), but the 2006 WHO standards exclude infants shorter than 45 cm. In older children, midupper arm circumference (MUAC) predicts mortality better than does WLZ. Outcomes may also be influenced by exposure to HIV and size or gestational age at birth. Diagnostic thresholds for WLZ, MUAC, and other indexes have not been fully evaluated against mortality risk among U6M infants.Objective: The aim was to determine the association of anthropometric indexes with risks of inpatient and postdischarge mortality among U6M infants recruited at the time of hospitalization.Design: We analyzed data from a cohort of U6M infants admitted to Kilifi County Hospital (2007-2013), Kenya. The primary outcomes were inpatient death and death during follow-up over 1 y after discharge. We calculated adjusted RRs for inpatient mortality and HRs for postdischarge mortality for different anthropometric measures and thresholds. Discriminatory value was assessed by using receiver operating characteristic curves.Results: A total of 2882 infants were admitted: 140 (4.9%) died in the hospital and 1405 infants were followed up after discharge. Of these, 75 (5.3%) died within 1 y during 1318 child-years of observation. MUAC and weight-for-age z score (WAZ) predicted inpatient and postdischarge mortality better than did WLZ (P < 0.0001). A single MUAC threshold of <11.0 cm performed similarly to MUAC thresholds that varied with age (all P > 0.05) and performed better than WLZ <-3 for both inpatient and postdischarge mortality (both P < 0.001). Reported small size at birth did not reduce the risk of death associated with anthropometric indexes.Conclusions: U6M infants at the highest risk of death are best targeted by using MUAC or WAZ. Further research into the effectiveness of potential interventions is required.

Correlation between rapid HIV testing and fourth-generation ELISA results for HIV detection among pregnant patients in the delivery room. Int J Gynaecol Obstet 2017; 137:31-33. [PMID: 28099753 DOI: 10.1002/ijgo.12094] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2016] [Revised: 11/09/2016] [Accepted: 01/03/2017] [Indexed: 11/11/2022]
Abstract
OBJECTIVE To analyze the usefulness of rapid HIV testing in pregnant patients in the delivery room. METHODS This prospective study compared a rapid test and a fourth-generation enzyme-linked immunoassay (ELISA) for HIV screening among pregnant patients admitted in labor with an unknown HIV status at a university hospital in Mexico between July 2015 and February 2016. Pearson correlation analysis was performed, and the diagnostic accuracy of the two tests was assessed with HIV RNA polymerase chain reaction (PCR) as the reference method. RESULTS Overall, 534 patients were included. With a signal-to-cutoff (S/CO) value of 1.0 or more as a diagnostic criterion, 6 (1.1%) patients had a positive ELISA result. Three had a negative rapid test and three had a positive test (r=0.705). With an S/CO value of 2.0 or more as cutoff, 4 (0.7%) patients had a positive ELISA result. Three had a positive rapid test and one had a negative test (r=0.865). Only three of six patients with an S/CO of 1.0 or more were confirmed to have HIV by RNA PCR. CONCLUSION The rapid test showed a strong correlation with the fourth-generation ELISA. Therefore, rapid testing is a useful tool in the delivery room for patients with unknown HIV status.

HIV-Exposed Uninfected Infants Show Robust Memory B-Cell Responses in Spite of a Delayed Accumulation of Memory B Cells: an Observational Study in the First 2 Years of Life. CLINICAL AND VACCINE IMMUNOLOGY : CVI 2016; 23:576-85.

Abstract
Improved HIV care has led to an increase in the number of HIV-exposed uninfected (HEU) infants born to HIV-infected women. Although they are uninfected, these infants experience increased morbidity and mortality. One explanation may be that their developing immune system is altered by HIV exposure, predisposing them to increased postnatal infections. We explored the impact of HIV exposure on the B-cell compartment by determining the B-cell subset distribution, the frequency of common vaccine antigen-specific memory B cells (MBCs), and the levels of antibodies to the respective antigens in HEU and HIV-unexposed uninfected (HUU) infants born to uninfected mothers, using flow cytometry, a B-cell enzyme-linked immunosorbent spot assay, and an enzyme-linked immunosorbent assay, respectively, during the first 2 years of life. For the majority of the B-cell subsets, there were no differences between HEU and HUU infants. However, HIV exposure was associated with a lower proportion of B cells in general and MBCs in particular, largely due to a lower proportion of unswitched memory B cells. This reduction was maintained even after correcting for age. These phenotypic differences in the MBC compartment did not affect the ability of HEU infants to generate recall responses to previously encountered antigens or reduce the antigen-specific antibody levels at 18 months of life. Although HIV exposure was associated with a transient reduction in the proportion of MBCs, we found that the ability of HEU infants to mount robust MBC and serological responses was unaffected.

Altered Memory T-Cell Responses to Bacillus Calmette-Guerin and Tetanus Toxoid Vaccination and Altered Cytokine Responses to Polyclonal Stimulation in HIV-Exposed Uninfected Kenyan Infants. PLoS One 2015; 10:e0143043. [PMID: 26569505 PMCID: PMC4646342 DOI: 10.1371/journal.pone.0143043] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2015] [Accepted: 10/29/2015] [Indexed: 11/21/2022] Open
Abstract
Implementation of successful prevention of mother-to-child transmission of HIV strategies has resulted in an increased population of HIV-exposed uninfected (HEU) infants. HEU infants have higher rates of morbidity and mortality than HIV-unexposed (HU) infants. Numerous factors may contribute to poor health in HEU infants including immunological alterations. The present study assessed T-cell phenotype and function in HEU infants with a focus on memory Th1 responses to vaccination. We compared cross-sectionally selected parameters at 3 and 12 months of age in HIV-exposed (n = 42) and HU (n = 28) Kenyan infants. We measured ex vivo activated and bulk memory CD4 and CD8 T-cells and regulatory T-cells by flow cytometry. In addition, we measured the magnitude, quality and memory phenotype of antigen-specific T-cell responses to Bacillus Calmette-Guerin and Tetanus Toxoid vaccine antigens, and the magnitude and quality of the T cell response following polyclonal stimulation with staphylococcal enterotoxin B. Finally, the influence of maternal disease markers on the immunological parameters measured was assessed in HEU infants. Few perturbations were detected in ex vivo T-cell subsets, though amongst HEU infants maternal HIV viral load positively correlated with CD8 T cell immune activation at 12 months. Conversely, we observed age-dependent differences in the magnitude and polyfunctionality of IL-2 and TNF-α responses to vaccine antigens particularly in Th1 cells. These changes mirrored those seen following polyclonal stimulation, where at 3 months, cytokine responses were higher in HEU infants compared to HU infants, and at 12 months, HEU infant cytokine responses were consistently lower than those seen in HU infants. Finally, reduced effector memory Th1 responses to vaccine antigens were observed in HEU infants at 3 and 12 months and higher central memory Th1 responses to M. tuberculosis antigens were observed at 3 months only. Long-term monitoring of vaccine efficacy and T-cell immunity in this vulnerable population is warranted.
