Background We estimated the prevalence of long COVID and impact on daily living among a representative sample of adults in the United States. Methods We conducted a population-representative survey, 30 June–2 July 2022, of a random sample of 3042 US adults aged 18 years or older and weighted to the 2020 US population. Using questions developed by the UK's Office of National Statistics, we estimated the prevalence of long COVID, by sociodemographics, adjusting for gender and age. Results An estimated 7.3% (95% confidence interval: 6.1–8.5%) of all respondents reported long COVID, corresponding to approximately 18 828 696 adults. One-quarter (25.3% [18.2–32.4%]) of respondents with long COVID reported their day-to-day activities were impacted “a lot” and 28.9% had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection more than 12 months ago. The prevalence of long COVID was higher among respondents who were female (adjusted prevalence ratio [aPR]: 1.84 [1.40–2.42]), had comorbidities (aPR: 1.55 [1.19–2.00]), or were not (vs were) boosted (aPR: 1.67 [1.19–2.34]) or not vaccinated (vs boosted) (aPR: 1.41 [1.05–1.91]). Conclusions We observed a high burden of long COVID, substantial variability in prevalence of SARS-CoV-2, and risk factors unique from SARS-CoV-2 risk, suggesting areas for future research. Population-based surveys are an important surveillance tool and supplement to ongoing efforts to monitor long COVID.

In a population-based survey of adults in New York City, we assessed positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests (including via exclusive at-home testing) and possible cases among untested respondents. An estimated 27.4% (95% confidence interval [CI]: 22.8%–32.0%) or 1.8 million adults (95% CI: 1.6–2.1 million) had SARS-CoV-2 infection between 1 January and 16 March 2022.

We describe tuberculosis (TB) disease among antiretroviral treatment (ART) eligible children living with HIV (CLHIV) in South Africa to highlight TB prevention opportunities.In our secondary analysis among 0- to 12-year-old ART-eligible CLHIV in five Eastern Cape Province health facilities from 2012 to 2015, prevalent TB occurred 90 days before or after enrollment; incident TB occurredgt;90 days after enrollment. Characteristics associated with TB were assessed using logistic and Cox proportional hazards regression with generalized estimating equations.Of 397 enrolled children, 114 (28.7%) had prevalent TB. Higher-income proxy [adjusted odds ratio (aOR) 1.8 [95% confidence interval (CI) 1.3-2.6] for the highest, 1.6 (95% CI 1.6-1.7) for intermediate]; CD4+ cell countlt;350 cells/µl [aOR 1.6 (95% CI 1.1-2.2)]; and malnutrition [aOR 1.6 (95% CI 1.1-2.6)] were associated with prevalent TB. Incident TB was 5.2 per 100 person-years and was associated with delayed ART initiation [hazard ratio (HR) 4.7 (95% CI 2.3-9.4)], malnutrition [HR 1.8 (95% CI 1.1-2.7)] and absence of cotrimoxazole [HR 2.3 (95% CI 1.0-4.9)]. Among 362 children with data, 8.6% received TB preventive treatment.Among these CLHIV, prevalent and incident TB were common. Early ART, cotrimoxazole and addressing malnutrition may prevent TB in these children.We describe tuberculosis (TB) in children living with HIV (CLHIV) eligible for HIV treatment in South Africa to highlight opportunities to prevent TB.We analyzed additional data from our original study of CLHIV who were 0–12 years old and due to start HIV treatment in five health facilities in Eastern Cape Province from 2012 to 2015 and assessed characteristics associated with existing and new TB.Of 397 enrolled children, 114 (28.7%) had existing TB. Children with a higher measure of household income had higher odds of existing TB. CD4+ cell countlt;350 cells/µl and malnutrition were also associated with existing TB. There were 5.2 new cases of TB for every 100 child-years. New TB was 4.7 times more likely for children with delayed HIV treatment start, 1.8 times more likely for children with malnutrition and 2.3 times more likely for children who did not get cotrimoxazole. Among 362 children with data, 8.6% received treatment to prevent TB.Among these CLHIV, existing and new TB were common. Early HIV treatment, cotrimoxazole and addressing malnutrition may prevent TB in these children.

Background Adolescents aged 10–19 years living with human immunodeficiency virus (HIV) (ALHIV), both perinatally infected adolescents (APHIV) and behaviorally infected adolescents (ABHIV), are a growing population with distinct care needs. We characterized the epidemiology of HIV in adolescents included in Population-based HIV Impact Assessments (2015–2017) in Zimbabwe, Malawi, Zambia, Eswatini, and Lesotho. Methods Adolescents were tested for HIV using national rapid testing algorithms. Viral load (VL) suppression (VLS) was defined as VL, Based on national surveys, fewer than half of adolescents living with human immunodeficiency virus (HIV) in 5 countries in southern Africa were virally suppressed, and 68.7% classified as perinatally infected had undiagnosed HIV or HIV diagnosed at age ≥10 years.

Background Children living with human immunodeficiency virus (HIV) (CLHIV) receiving antiretroviral therapy (ART) in resource-limited settings are susceptible to high rates of acquired HIV drug resistance (HIVDR), but few studies include children initiating age-appropriate World Health Organization (WHO)-recommended first-line regimens. We report data from a cohort of ART-naive South African children who initiated first-line ART. Methods ART-eligible CLHIV aged 0–12 years were enrolled from 2012 to 2014 at 5 public South African facilities and were followed for up to 24 months. Enrolled CLHIV received standard-of-care WHO-recommended first-line ART. At the final study visit, a dried blood spot sample was obtained for viral load and genotypic resistance testing. Results Among 72 successfully genotyped CLHIV, 49 (68.1%) received ABC/3TC/LPV/r, and 23 (31.9%) received ABC/3TC/EFV. All but 2 children on ABC/3TC/LPV/r were Conclusions High levels of NNRTI and NRTI DRMs among CLHIV receiving ABC/3TC/LPV/r suggests a lasting impact of failed mother-to-child transmission interventions on DRMs. However, drug susceptibility analysis reveals that CLHIV with detectable viremia on ABC/3TC/LPV/r are more likely to have maintained at least 2 effective agents on their current HIV regimen than those on ABC/3TC/EFV.

INTRODUCTION: HIV testing at birth of HIV-exposed infants (HEIs) may improve the identification of infants infected with HIV in utero and accelerate antiretroviral treatment (ART) initiation. METHODS: ICAP at Columbia University supported implementation of a national pilot of HIV testing at birth (0–7 days) in Eswatini at 2 maternity facilities. Dried blood spot (DBS) samples from neonates of women living with HIV (WLHIV) were collected and processed at the National Molecular Reference Laboratory using polymerase chain reaction (PCR). Mothers received birth test results at community health clinics. We report data on HIV birth testing uptake and outcomes for HIV-positive infants from the initial intensive phase (October 2017–March 2018) and routine support phase (April–December 2018). RESULTS: During the initial intensive pilot phase, 1669 WLHIV delivered 1697 live-born HEI at 2 health facilities and 1480 (90.3%) HEI received birth testing. During the routine support phase, 2546 WLHIV delivered and 2277 (93.5%) HEI received birth testing. Overall October 2017–December 2018, 22 (0.6%) infants of 3757 receiving birth testing had a positive PCR test, 15 (68.2%) of whom were successfully traced and linked for confirmatory testing (2 infants were reported by caregivers to have negative follow-up HIV tests). Median time from birth test to receipt of results by the caregiver was 13 days (range: 8–23). Twelve (60.0%) of 20 infants confirmed to be HIV-positive started ART at median age of 17.5 days (12–43). One mother of an HIV-positive infant who was successfully traced refused ART following linkage to care and another child died after ART initiation. Three infants (15.0%) had died by the time their mothers were reached and 4 (15.0%) infants were never located. CONCLUSION: This pilot of universal birth testing in Eswatini demonstrates the feasibility of using a standard of care approach in a low resource and high burden setting. We document high uptake of testing for newborns among HIV-positive mothers and very few infants were found to be infected through birth testing.

School-based vaccine mandates improve vaccination coverage in children. We conducted a cross-sectional survey of parents in New York City (NYC) in November 2021 to measure acceptability of COVID-19 vaccine mandates for students, and for teachers and school staff. Random address-based sampling was used to recruit parents of children 5-11 years of age. Among 2,506 parents surveyed, 44.3% supported school-based vaccine mandates for students and 69.1% supported mandates for teachers and school staff. Asian parents, male parents, those with higher income, college education, those voting for the 2021 Democratic mayoral candidate and parents from Manhattan were most likely to support vaccine mandates for students. Among all parents, 25.1% said they would not vaccinate their child if required. Our data show only modest support for school-based COVID-19 vaccine mandates for children despite their importance in improving vaccination coverage.

Introduction Young pregnant and postpartum women living with HIV (WLHIV) are at high risk of poor outcomes in prevention of mother‐to‐child transmission services. The aim of this systematic review was to collate evidence on strategies to improve retention in antenatal and/or postpartum care in this population. We also conducted a secondary review of strategies to increase attendance at antenatal care (ANC) and/or facility delivery among pregnant adolescents, regardless of HIV status, to identify approaches that could be adapted for adolescents and young WLHIV. Methods Selected databases were searched on 1 December 2020, for studies published between January 2006 and November 2020, with screening and data abstraction by two independent reviewers. We identified papers that reported age‐disaggregated results for adolescents and young WLHIV aged

BACKGROUND Poor growth and metabolic disturbances remain concerns for children living with HIV (CLHIV). We describe the impact of viral load (VL) on growth and lipid outcomes in South African CLHIV

Introduction Women living with HIV are required to transition into the prevention of mother‐to‐child transmission of HIV (PMTCT) services when they become pregnant and back to ART services after delivery. Transition can be a vulnerable time when many women are lost from HIV care yet there is little guidance on the optimal transition approaches to ensure continuity of care. We reviewed the available evidence on existing approaches to transitioning women into and out of PMTCT, outcomes following transition and factors influencing successful transition. Methods We searched PubMed and SCOPUS, as well as abstracts from international HIV‐focused meetings, from January 2006 to July 2020. Studies were included that examined three points of transition: pregnant women already on ART into PMTCT (transition 1), pregnant women living with HIV not yet on ART into treatment services (transition 2) and postpartum women from PMTCT into general ART services after delivery (transition 3). Results were grouped and reported as descriptions of transition approach, comparison of outcomes following transition and factors influencing successful transition. Results & discussion Out of 1809 abstracts located, 36 studies (39 papers) were included in this review. Three studies included transition 1, 26 transition 2 and 17 transition 3. Approaches to transition were described in 26 studies and could be grouped into the provision of information at the point of transition (n = 8), strengthened communication or linkage of data between services (n = 4), use of transition navigators (n = 12), and combination approaches (n = 4). Few studies were designed to directly assess transition and only nine compared outcomes between transition approaches, with substantial heterogeneity in study design, setting and outcomes. Four themes were identified in 25 studies reporting on factors influencing successful transition: fear, knowledge and preparedness, clinic characteristics and the transition requirements and process. Conclusions This review highlights that, despite the need for women to transition into and out of PMTCT services for continued ART in many settings, there is very limited evidence on optimal transition approaches. Ongoing operational research is required to identify sustainable and acceptable transition approaches and service delivery models that support continuity of HIV care during and after pregnancy.

Background Increased coagulation biomarkers are associated with poor outcomes among people living with HIV (PLHIV). There are few data available from African cohorts demonstrating the effect of antiretroviral therapy (ART) on coagulation biomarkers. Methods From March 2014 to October 2014, ART-naïve PLHIV initiating non-nucleoside reverse transcriptase inhibitor-based ART were recruited from seven clinics in western Kenya and followed for up to 12 months. Demographics, clinical history and blood specimens were collected. Logistic regression models adjusted for intrasite clustering examined associations between HIV viral load and D-Dimer at baseline. Mixed linear effects models were used to estimate mean change from baseline to 6 months overall, and by baseline viral load, sex and TB status at enrollment. Mean change in D-dimer at 6 months is reported on the log10 scale and as percentage change from baseline. Results Among 611 PLHIV enrolled, 66% were female, median age was 34 years (interquartile range (IQR) 29–43 years), 31 (5%) participants had tuberculosis and median viral load was 113,500 copies/mL (IQR: 23,600-399,000). At baseline, 311 (50.9%) PLHIV had elevated D-dimer (> 500 ng/mL) and median D-dimer was 516.4 ng/mL (IQR: 302.7–926.6) (log baseline D-dimer: 2.7, IQR: 2.5–3.0). Higher baseline D-dimer was significantly associated with higher viral load (p p = 0.02) and tuberculosis (p = 0.02). After 6 months on ART, 518 (84.8%) PLHIV had achieved viral load p p 6.0 copies/mL (− 91.1, 95%CI −136.7, − 54.2; p Conclusions In this large Kenyan cohort of PLHIV, women, those with tuberculosis and higher viral load had elevated baseline D-dimer. ART initiation and viral load suppression among ART-naïve PLHIV in Kenya were associated with significant decrease in D-dimer at 6 months in this large African cohort.

Objective To describe pediatric ART scale-up in Ethiopia, one of the 21 global priority countries for elimination of pediatric HIV infection. Methods A descriptive analysis of routinely collected HIV care and treatment data on HIV-infected children (

BACKGROUND Estimates of incidence of switching to second-line antiretroviral therapy (ART) among children with HIV are necessary to inform the need for paediatric second-line formulations. We aimed to quantify the cumulative incidence of switching to second-line ART among children in an international cohort collaboration. METHODS In this international cohort collaboration study, we pooled individual patient-level data for children younger than 18 years who initiated ART (two or more nucleoside reverse-transcriptase inhibitors [NRTI] plus a non-NRTI [NNRTI] or boosted protease inhibitor) between 1993 and 2015 from 12 observational cohort networks in the Collaborative Initiative for Paediatric HIV Education and Research (CIPHER) Global Cohort Collaboration. Patients who were reported to be horizontally infected with HIV and those who were enrolled in trials of treatment monitoring, switching, or interruption strategies were excluded. Switch to second-line ART was defined as change of one or more NRTI plus either change in drug class (NNRTI to protease inhibitor or vice versa) or protease inhibitor change, change from single to dual protease inhibitor, or addition of a new drug class. We used cumulative incidence curves to assess time to switching, and multivariable proportional hazards models to explore patient-level and cohort-level factors associated with switching, with death and loss to follow-up as competing risks. FINDINGS At the data cutoff of Sept 16, 2015, 182 747 children with HIV were included in the CIPHER dataset, of whom 93 351 were eligible, with 83 984 (90·0%) from sub-Saharan Africa. At ART initiation, the median patient age was 3·9 years (IQR 1·6-6·9) and 82 885 (88·8%) patients initiated NNRTI-based and 10 466 (11·2%) initiated protease inhibitor-based regimens. Median duration of follow-up after ART initiation was 26 months (IQR 9-52). 3883 (4·2%) patients switched to second-line ART after a median of 35 months (IQR 20-57) of ART. The cumulative incidence of switching at 3 years was 3·1% (95% CI 3·0-3·2), but this estimate varied widely depending on the cohort monitoring strategy, from 6·8% (6·5-7·2) in settings with routine monitoring of CD4 (CD4% or CD4 count) and viral load to 0·8% (0·6-1·0) in settings with clinical only monitoring. In multivariable analyses, patient-level factors associated with an increased likelihood of switching were male sex, older age at ART initiation, and initial NNRTI-based regimen (p

Introduction There are limited data on viral suppression (VS) in children with HIV receiving antiretroviral therapy (ART) in routine care in low‐resource settings. We examined VS in a cohort of children initiating ART in routine HIV care in Eastern Cape Province, South Africa. Methods The Pediatric Enhanced Surveillance Study enrolled HIV‐infected ART eligibility children zero to twelve years at five health facilities from 2012 to 2014. All children received routine HIV care and treatment services and attended quarterly study visits for up to 24 months. Time to VS among those starting treatment was measured from ART start date to first viral load (VL) result 30 days after the VS date. Results Of 397 children enrolled, 349 (87.9%) started ART: 118 (33.8%) children age 1 million copies/mL at ART initiation were half as likely to achieve VS 1000 copies/mL. Children 1000 copies/mL (adjusted relative risk 2.03, 95% CI: 1.10 to 3.74) compared with six to twelve year olds. Conclusions We found suboptimal VS among South African children initiating treatment and high proportions experiencing VL rebound, particularly among younger children. Greater efforts are needed to ensure that all children achieve optimal outcomes.

BACKGROUND: Delayed initiation of antiretroviral therapy (ART) in eligible patients is a concern in resource-limited countries. METHODS: We analyzed data on HIV-positive patients >/=15 years enrolled at 41 ICAP-supported health care facilities in Rwanda 2005-2010 to determine time to ART initiation among patients eligible at enrollment compared with those ineligible or of indeterminate eligibility who become eligible during follow-up. ART eligibility was based on CD4 cell count (CD4) and WHO staging; patients lacking CD4 and WHO stage were considered indeterminate. Cumulative incidence of reaching ART eligibility and to ART initiation after eligibility was generated using competing risk estimators. RESULTS: A total of 31033 ART-naive adults were enrolled; 64.2% were female. At enrollment 10158 (32.7%) patients were ART eligible 13372 (43.1%) were ineligible for ART and 7503 (24.2%) patients were indeterminate. Among patients retained in care pre-ART eligibility 17.9% [95% confidence interval (CI): 17.2 to 18.6] of ineligible and 22.8% (95% CI: 21.7 to 23.8) of indeterminate patients at enrollment reached ART eligibility within 12 months. Cumulative incidence of ART initiation within 3 months for patients eligible at enrollment was 77.2% (95% CI: 76.4 to 78.0) compared with 67.9% (95% CI: 66.4 to 69.3) for ineligible and 63.8% (95% CI: 61.9 to 65.8) for patients with indeterminate eligibility at enrollment (P < 0.05). Over the study period there was more rapid ART initiation for patients who became ART eligible. CONCLUSIONS: We found higher rates of ART initiation within 3 months among patients who were ART eligible at enrollment compared with those who reached eligibility during follow-up. From 2006 to 2011 earlier initiation of ART after eligibility was observed likely reflecting improved program quality.

Scale-up of HIV care and antiretroviral therapy (ART) services for children has expanded access, but significant gaps and challenges remain. We examined lost to follow-up (LTF) and mortality in a large cohort of children enrolled in HIV care in Mozambique.Routinely collected medical data on children 0-14 years enrolled in care 2009-2013 at ICAP-supported health facilities in 5 provinces of Mozambique were used. Children not receiving ART (pre-ART) were considered LTF if they did not a have a visit within 12 months of the end of data collection; for those receiving ART, LTF was no visit within 6 months. Competing risk and Kaplan-Meier estimators were used, respectively, to estimate pre-ART and on ART LTF and mortality.A total of 13,695 children enrolled in HIV care at 64 health facilities (48.6%,2 years), and 7733 (56.5%) initiated ART during follow-up. Cumulative incidence of pre-ART LTF was 32.9% [95% confidence interval (CI): 32.1-33.7] and 34.4% (95% CI: 33.6-35.2) by 12 and 24 months, respectively, and was highest in children5 years (12-month LTF in children 2-4 years, 34.2%, 95% CI: 32.6-35.9). Pre-ART mortality at 12 months was 3.3% (95% CI: 3.0-3.6) and was highest in children2 years (4.1%, 95% CI: 3.6-4.6). On ART, LTF was 28.6% (95% CI: 27.6-29.7) and 37.6 (95% CI: 36.4-38.8) at 12 and 24 months, and 12 months mortality after ART was 8.0% (95% CI: 7.3-8.7).High rates of LTF were observed in this large cohort of HIV-infected children accessing care in Mozambique both before and after ART initiation highlighting the urgent need for interventions to improve retention in routine care settings.

To the Editors:There are an estimated 2.9 million 10–24-year-olds living with HIV in sub-Saharan Africa,1 and these numbers are expected to increase with improved survival among perinatally infected children and as a result of new behaviorally acquired infections among older adolescents and youth.2

HIV/AIDS has had a profound impact on children around the world since the start of the epidemic. There are currently 3.4 million children under the age of 15 years living with HIV globally, and more than 450,000 children currently receiving lifesaving antiretroviral treatment. This article describes efforts supported by the President’s Emergency Plan for AIDS Relief (PEPFAR) to expand access to treatment for children living with HIV in high-burden countries. The article also highlights a series of case studies that illustrate the impact that the PEPFAR initiative has had on the pediatric HIV epidemic. Through its support of host governments and partner organizations, the PEPFAR initiative has expanded HIV testing and treatment for pregnant women to reduce vertical transmission of HIV, increased access to early infant diagnosis for HIV-exposed infants, improved training and resources for clinicians who provide pediatric care and antiretroviral treatment, and, through public–private partnerships with pharmaceutical manufacturers, helped increase the number of medications available for the treatment of HIV-infected children in resource-limited settings.

Prevalence of sexually transmitted infections (STI) is high among pregnant women in certain settings. We estimated STI incidence and compared STI risk in pregnant and non-pregnant women. Data came from the Methods for Improving Reproductive Health in Africa (MIRA) study conducted in South Africa and Zimbabwe 2003-2006. Women aged 18-50 years with at least one follow-up visit within 6 months of enrollment were included. Follow-up visits included laboratory testing for pregnancy, chlamydia, gonorrhea, trichomoniasis, and HIV, as well as self-report of hormonal contraceptive (HC) use, sexual behaviors and intravaginal practices. All visits were classified according to pregnancy status. Incidence of each STI was calculated using follow-up time. Cox proportional hazards models were fitted using pregnancy as a time-varying exposure and sexual behaviors and intravaginal practices as time-varying covariates. Among 4,549 women, 766 (16.8%) had a positive pregnancy test. Median follow-up time was 18 months [IQR: 12-24]. The overall incidence rate of chlamydia was 6.7 per 100 person years (py) and 9.9/100py during pregnancy; gonorrhea incidence was 2.7/100py and 4.9/100py during pregnancy; trichomoniasis incidence was 7.1/100py overall and 9.2/100py during pregnancy. Overall HIV incidence was 3.9/100py and 3.8/100py during pregnancy. In crude models, pregnancy increased risk for chlamydia (hazard ratio (HR) 1.5, 95%CI: 1.1-1.2), however there was no increased risk of any measured STI in adjusted models. STI Incidence was high during pregnancy however pregnancy did not increase STI risk after adjustment for sexual behaviors. Greater efforts are needed to help pregnant women avoid STIs.

Introduction: The number of adolescents with perinatally or behaviourally acquired HIV is increasing in low-income countries, and especially in sub-Saharan Africa where HIV prevalence and incidence are the highest. As they survive into adulthood in the era of antiretroviral therapy, there is a pressing need to transfer them from paediatric to adult care, known as the transition of care. We conducted a narrative review of recent evidence on their transition outcomes in Africa, highlighting the specific needs and challenges in these populations and settings, and the different models of care for transition. Areas covered: We searched PubMed bibliographic database, HIV conference content, and grey literature from January 2000 to August 2016 with the following keywords: HIV infections AND (adolescents or youth) AND transition AND Africa. All qualitative and quantitative, experimental and observational studies including HIV-infected patients aged 10–24 years with information on transition were eligible. Results: Few data on transition outcomes for HIV-infected adolescents are available from Africa settings. Studies mainly from Southern and East Africa reported on the barriers to successful transition, highlighting several gaps. These included lack of adequate infrastructure, staff training and communication between paediatric and adult clinicians as well as the fear of stigma of adolescents and youth living with HIV. Most countries have no specific national guidelines on when to disclose HIV status or when and how to transition to adult care. Several models of care adapted to the adolescent transition question have been implemented in specific settings. These models include teen clinics, peer educators or the use of social media. However, regardless of the model, services are increasingly overburdened and have insufficient human resources. Furthermore, very high attrition has been observed among adolescents and youth compared to younger children or older adults. There is a need to identify sub-groups at higher risk of loss to follow-up for targeted care and peer support. Expert commentary: Although the available HIV-related data on adolescent transition outcomes are limited, there is evidence of their increased vulnerability during this period. Standardized data gathering, analysis, and reporting systems specific to adolescent transition are essential to improve understanding and adolescent outcomes in Africa.

Introduction : Decentralization of HIV care for children has been recommended to improve paediatric outcomes by making antiretroviral treatment (ART) more accessible. We documented outcomes of children transferred after initiating ART at a large tertiary hospital in the Eastern Cape of South Africa. Methods : Electronic medical records for all children 0–15 years initiating ART at Dora Nginza Hospital (DNH) in Port Elizabeth, South Africa January 2004 to September 2015 were examined. Records for children transferred to primary and community clinics were searched at 16 health facilities to identify children with successful (at least one recorded visit) and unsuccessful transfer (no visits). We identified all children lost to follow-up (LTF) after ART initiation: those LTF at DNH (no visit >6 months), children with unsuccessful transfer, and children LTF after successful transfer (no visit >6 months). Community tracing was conducted to locate caregivers of children LTF and electronic laboratory data were searched to measure reengagement in care, including silent transfers. Results : 1,582 children initiated ART at median age of 4 years [interquartile range (IQR): 1–8] and median CD4+ of 278 cells/mm 3 [IQR: 119–526]. A total of 901 (57.0%) children were transferred, 644 (71.5%) to study facilities; 433 (67.2%) children had successful transfer and 211 (32.8%) had unsuccessful transfer. In total, 399 children were LTF: 105 (26.3%) from DNH, 211 (52.9%) through unsuccessful transfer and 83 (20.8%) following successful transfer. Community tracing was conducted for 120 (30.1%) of 399 children LTF and 66 (55.0%) caregivers were located and interviewed. Four children had died. Among 62 children still alive, 8 (12.9%) were reported to not be in care or taking ART and 18 (29.0%) were also not taking ART. Overall, 65 (16.3%) of 399 children LTF had a laboratory result within 18 months of their last visit indicating silent transfer and 112 (28.1%) had lab results from 2015 to 2016 indicating current care. Conclusion : We found that only two-thirds of children on ART transferred to primary and community health clinics had successful transfer. These findings suggest that transfer is a particularly vulnerable step in the paediatric HIV care cascade.

BACKGROUND: The number of youth and adolescents (10-24 years) with HIV infection has increased substantially presenting unique challenges to effective health service delivery. METHODS: We examined routinely collected patient-level data for antiretroviral treatment (ART)-naive HIV-infected patients aged 10-24 years enrolled in care during 2006-2011 at 109 ICAP-supported health facilities in three provinces in Kenya. Loss to follow-up (LTF) was defined as having no clinic visit for 12 months prior to ART initiation (pre-ART) and 6 months for ART patients. Competing risk and Kaplan-Meier estimators were used to calculate LTF and death rates. Sub-distributional and Cox proportional-hazards models were used to identify potential predictors of death and LTF. RESULTS: Overall 22 832 patients were enrolled in care at 10-24 years of age 69.5% were aged 20-24 years and 82% were female. Median CD4(+) cell count was 332 cells/mul (interquartile range 153-561); 70.8% were WHO stage I/II. Young adolescents (10-14 years) had more advanced WHO stage and lower median CD4(+) cell count compared to youth (15-24 years) at enrollment (284 vs. 340 cells/mul; P < 0.0001). Cumulative incidence of LTF and death at 24 months for pre-ART patients was 46.1% [95% confidence interval (CI) 45.4-46.8%) and 2.1% (95% CI 1.9-2.3%) respectively. For those on ART 32.2% (95% CI 31.1-33.3%) were LTF and 3.9% (95% CI 1.7-2.3%) died within 24 months. LTF among pre-ART and ART patients was twice as high among youth compared to young adolescents. CONCLUSION: LTF of young people with HIV in this Kenyan cohort was high and notably greater among youth compared to young adolescents. Novel strategies targeting these populations are urgently needed to improve retention.

Background Antiretroviral therapy (ART) improves morbidity and mortality in patients with HIV, however high rates of loss to follow-up (LTF) and mortality have been documented in HIV care and treatment programs. Methods We analyzed routinely-collected data on HIV-infected patients ≥15 years enrolled at 41 healthcare facilities in Rwanda from 2005 to 2010. LTF was defined as not attending clinic in the last 12 months for pre-ART patients and 6 months for ART patients. For the pre-ART period, sub-distribution hazards models were constructed to estimate LTF and death to account for competing risks. Kaplan-Meier (KM) and Cox proportional hazards models were used for patients on ART. Results 31,033 ART-naïve adults were included, 64% were female and 75% were WHO stage I or II at enrollment. 17,569 (56%) patients initiated ART. Pre-ART competing risk estimates of LTF at 2 years was 11.2% (95%CI, 10.9–11.6%) and 2.9% for death (95%CI 2.7–3.1%). Among pre-ART patients, male gender was associated with higher LTF (adjusted sub-hazard ratio (aSHR) 1.3, 95%CI 1.1–1.5) and death (aSHR 1.7, 95%CI 1.4–2.1). Low CD4 count (CD4

Efforts to scale-up HIV treatment in high burden countries have resulted in wider access to care, improved survival and decreased morbidity for HIV-infected children. The country of Rwanda has made significant achievements in expanding coverage of pediatric HIV services.We describe the extent of and factors associated with mortality and lost to follow-up (LTF) in children (15 years) enrolled in HIV care at 39 ICAP-supported facilities across Rwanda from 2004 to 2010 by antiretroviral treatment (ART) status. We estimated the 1-year cumulative incidence of death and LTF among all children enrolled in care (pre-ART) and children on ART. Survival analysis was used to evaluate factors associated with death and LTF in both groups.Between January 2004 and June 2010, 3244 children with a median age of 5.7 years (interquartile range 2.8-9.6) enrolled in HIV care. One-year cumulative incidence for death and LTF among pre-ART children was 4% (95% confidence interval [CI]: 3-5%) and 5% (95% CI: 4-6%), respectively. Overall, 2035 (63%) children initiated ART, median age 6.3 years (interquartile range 3.3-10.4): 1-year Kaplan-Meier estimates of death and LTF were 3% (95% CI: 3-4%) and 1% (95% CI: 1-2%), respectively. Factors associated with an increased hazard for death among pre-ART children included being18 months old versus ≥5 years (adjusted sub hazard ratio [aSHR] = 4.4, 95% CI: 2.9-6.8) and World Health Organization stage IV versus I (aSHR = 4.1, 95% CI: 2.0-8.4), whereas children entering care through prevention of mother-to-child transmission had lower hazard than those from voluntary counseling and testing (aSHR = 0.50, 95% CI: 0.25-1.0). Markers of advanced disease, including severe immunosuppression (aSHR = 0.25, 95% CI: 0.12-0.54), and enrollment in care in rural versus urban clinics (aSHR = 0.71, 95% CI: 0.53-0.97) were protective against LTF. For children on ART, factors associated with hazard of death included younger age (adjusted hazard ratio [aHR]18 months versus ≥5 years = 2.1, 95% CI: 1.3-3.6), severe malnutrition versus not malnourished (aHR = 3.2, 95% CI: 1.3-8.1), advanced World Health Organization stage (aHR IV versus I = 9.8, 95% CI: 3.5-27.4) and severe immunodeficiency versus no evidence (aHR = 2.3, 95% CI: 1.7-3.3). No associations were observed with LTF among children on ART.The results demonstrate very high retention among children enrolled in HIV care in Rwanda. Younger children continue to be particularly vulnerable, underscoring the urgent need for early identification, rapid treatment initiation and long-term retention in care.

High levels of adherence to antiretroviral therapy are considered necessary to achieve viral suppression. We analyzed data from a cohort of HIV-infected children who were2 years of age receiving protease inhibitor-based antiretroviral therapy to investigate associations between viral suppression and adherence ascertained using different methods.Data were from the prerandomization phase of a clinical trial in South Africa of HIV-infected children initiating either ritonavir-boosted lopinavir (LPV/r) or ritonavir-based antiretroviral therapy. At scheduled visits during the first 24 weeks of enrollment, study pharmacists measured quantities of medications returned to the clinic. Caregivers answered questionnaires on missed doses and adherence barriers. Associations between adherence and viral suppression (HIV-1 RNA400 copies/mL) were investigated by regimen.By 24 weeks, 197 of the 269 (73%) children achieved viral suppression. There was no association between viral suppression and caregiver reported missed doses or adherence barriers. For children receiving the LPV/r-based regimen, medication return adherence to each of the 3 drugs in the regimen (LPV/r, lamivudine or stavudine) individually or together was associated with viral suppression at different adherence thresholds. For example,85% adherence to any of the 3 medications significantly increased odds of lack of viral suppression (odds ratio: 2.30, 95% confidence interval: 1.30-4.07, P = 0.004). In contrast, for children receiving the ritonavir-based regimen, there was no consistent pattern of association between medication return and viral suppression.Caregiver reports of missed doses did not predict virologic response to treatment. Pharmacist medication reconciliation correlated strongly with virologic response for children taking a LPV/r-based regimen and appears to be a valid method for measuring pediatric adherence.

Since its inception in 2003, the US President’s Emergency Plan for AIDS Relief (PEPFAR) has been an important driving force behind the global scale-up of HIV care and treatment services, particularly in expansion of access to antiretroviral therapy. Despite initial concerns about cost and feasibility, PEPFAR overcame challenges by leveraging and coordinating with other funders, by working in partnership with the most affected countries, by supporting local ownership, by using a public health approach, by supporting task-shifting strategies, and by paying attention to health systems strengthening. As of September 2011, PEPFAR directly supported initiation of antiretroviral therapy for 3.9 million people and provided care and support for nearly 13 million people. Benefits in terms of prevention of morbidity and mortality have been reaped by those receiving the services, with evidence of societal benefits beyond the anticipated clinical benefits. However, much remains to be accomplished to achieve universal access, to enhance the quality of programs, to ensure retention of patients in care, and to continue to strengthen health systems.
