Seroconversion and seroprevalence of TORCH infections in a pregnant women cohort study, Mombasa, Kenya, 2017-2019.

Women infected during pregnancy with TORCH (Toxoplasmosis, Other, Rubella, Cytomegalovirus, and Herpes simplex viruses) pathogens have a higher risk of adverse birth outcomes including stillbirth / miscarriage because of mother-to-child transmission. To investigate these risks in pregnant women in Kenya, we analyzed serum specimens from a pregnancy cohort study at three healthcare facilities. A sample of 481 participants was selected for TORCH pathogen antibody testing to determine seroprevalence. A random selection of 285 from the 481 participants was selected to measure seroconversion. These sera were tested using an IgG enzyme-linked immunosorbent assay against 10 TORCH pathogens. We found that the seroprevalence of all but three of the 10 TORCH pathogens at enrollment was >30%, except for Bordetella pertussis (3.8%), Treponema pallidum (11.4%), and varicella zoster virus (0.5%). Conversely, very few participants seroconverted during their pregnancy and were herpes simplex virus type 2 (n = 24, 11.2%), parvovirus B19 (n = 14, 6.2%), and rubella (n = 12, 5.1%). For birth outcomes, 88% of the participant had live births and 12% had stillbirths or miscarriage. Cytomegalovirus positivity at enrolment had a statistically significant positive association with a live birth outcome (p = 0.0394). Of the 10 TORCH pathogens tested, none had an association with adverse pregnancy outcome.

Risk factors of adverse birth outcomes among a cohort of pregnant women in Coastal Kenya, 2017-2019.

INTRODUCTION: Adverse birth outcomes particularly preterm births and congenital anomalies, are the leading causes of infant mortality globally, and the burden is highest in developing countries. We set out to determine the frequency of adverse birth outcomes and the risk factors associated with such outcomes in a cohort of pregnant women in Kenya. METHODS: From October 2017 to July 2019, pregnant women < 28 weeks gestation were enrolled and followed up until delivery in three hospitals in coastal Kenya. Newborns were examined at delivery. Among women with birth outcome data, we assessed the frequency of congenital anomalies defined as gastroschisis, umbilical hernia, limb abnormalities and Trisomy 21, and adverse birth outcomes, defined as either stillbirth, miscarriage, preterm birth, small for gestational age, or microcephaly. We used log-binomial regression to identify maternal characteristics associated with the presence of at least one adverse outcome. RESULTS: Among the 2312 women enrolled, 1916 (82.9%) had birth outcome data. Overall, 402/1916 (20.9%; 95% confidence interval (CI): 19.1-22.8) pregnancies had adverse birth outcomes. Specifically, 66/1916 (3.4%; 95% CI: 2.7-4.4) were stillbirths, 34/1916 (1.8%; 95% CI: 1.2-2.4) were miscarriages and 23/1816 (1.2%; 95% CI: 0.8-1.9) had congenital anomalies. Among the participants with anthropometric measurements data, 142/1200 (11.8%; 95% CI: 10.1 - 13.8) were small for gestational age and among the participants with ultrasound records, 143/1711 (8.4%; 95% CI: 7.1-9.8) were preterm. Febrile illnesses in current pregnancy (adjusted risk ratio (aRR): 1.7; 95% CI: 1.1-2.8), a history of poor birth outcomes in prior pregnancy (aRR: 1.8; 95% CI: 1.3-2.4) and high blood pressure in pregnancy (aRR: 3.9, 95% CI: (1.7-9.2) were independently associated with adverse birth outcomes in a model that included age, education, human immunodeficiency virus status and high blood pressure at enrolment. CONCLUSION: We found similar rates of overall adverse birth outcomes, congenital anomalies, and small for gestational age but higher rates of stillbirths and lower rates of prematurity compared to the rates that have been reported in the sub-Saharan Africa region. However, the rates of adverse birth outcomes in this study were comparable to other studies conducted in Kenya. Febrile illnesses during the current pregnancy, previous history of poor birth outcomes and high blood pressure in pregnancy are predictive of an increased risk of adverse birth outcomes.

Association between low maternal serum aflatoxin B1 exposure and adverse pregnancy outcomes in Mombasa, Kenya, 2017-2019: A nested matched case-control study.

We examined the association between serum aflatoxin B1-lysine adduct (AFB1-lys) levels in pregnant women and adverse pregnancy outcomes (low birthweight, miscarriage and stillbirth) through a nested matched case-control study of pregnant women enroled at ≤28 weeks' gestation in Mombasa, Kenya, from 2017 to 2019. Cases comprised women with an adverse birth outcome, defined as either delivery of a singleton infant weighing <2500 g, or a miscarriage, or a stillbirth, while controls were women who delivered a singleton live infant with a birthweight of ≥2500 g. Cases were matched to controls at a ratio of 1:2 based on maternal age at enrolment, gestational age at enrolment and study site. The primary exposure was serum AFB1-lys. The study included 125 cases and 250 controls. The median gestation age when serum samples were collected was 23.0 weeks (interquartile range [IQR]: 18.1-26.0) and 23.5 (IQR: 18.1-26.5) among cases and controls, respectively. Of the 375 tested sera, 145 (38.7%) had detectable serum AFB1-lys: 36.0% in cases and 40.0% in controls. AFB1-lys adduct levels were not associated with adverse birth outcomes on multivariable analysis. Mid-upper arm circumference was associated with a 6% lower odds of adverse birth outcome for every unit increase (p = 0.023). Two-fifths of pregnant women had detectable levels of aflatoxin midway through pregnancy. However, we did not detect an association with adverse pregnancy outcomes, likely because of low serum AFB1-lys levels and low power, restricting meaningful comparison. More research is needed to understand the public health risk of aflatoxin in pregnant women to unborn children.

'They should show them love even if their status of being HIV positive is known': Youth and caregiver stigma experience and strategies to end HIV stigma in schools.

OBJECTIVE: HIV stigma and discrimination is widespread in sub-Saharan Africa and is associated with poor clinical outcomes. Schools play a critical role in the life of youth and have been identified as a potentially stigmatising environment. We sought to explore school HIV stigma drivers, facilitators, manifestations and outcomes among youth living with HIV (YLH) as well as potential stigma reduction interventions in Kenya. METHODS: Semi-structured in-depth qualitative interviews with 28 school-attending YLH aged 14-19 years and 24 caregivers of YLH were analysed using directed content analysis. Results were summarised using the Health and Stigma Framework. RESULTS: Drivers and facilitators of HIV stigma in the school environment included misconceptions about HIV transmission, HIV treatment outcomes and long-term overall health of people living with HIV. HIV stigma manifested largely as gossip, isolation and loss of friendships. Fear of HIV stigma or experienced stigma resulted in poor adherence to antiretroviral treatment-particularly among YLH in boarding schools-and poor mental health. Stigma also impacted school choice (boarding vs. day school) and prevented HIV disclosure to schools which was necessary for optimal support for care. Proposed interventions to address HIV stigma in schools included HIV education, psychosocial support for YLH, support for HIV disclosure to schools while ensuring confidentiality and building YLH resilience. CONCLUSION: There is an urgent need to develop interventions to address HIV stigma in schools to ensure optimised health and social outcomes for YLH. Future studies to understand the most effective and efficient interventions are needed.

Individual-, Interpersonal- and Institutional-Level Factors Associated with HIV Stigma Among Youth in Kenya.

HIV stigma remains a barrier in achieving optimal HIV treatment. We studied the prevalence and predictors of HIV stigma among adolescents and youth with HIV (AYWHIV) ages 15-24 years in Western Kenya. Of 1011 AYWHIV, 69% were female with a median age of 18 years. Most (59%) attended adolescent clinic days, and 40% attended support groups. One-quarter (27%) had experienced physical, 18% emotional, and 7% sexual violence. The majority of AYWHIV (88%) reported disclosure concerns, 48% reported perceived community stigma, 36% experienced, and 24% internalized stigma. Compared to AYWHIV attending adolescent clinics, those in general/adult clinics had higher internalized stigma. Similarly, having dropped out of school was associated with higher internalized stigma. AYWHIV in sexual relationships had higher experienced stigma and disclosure concerns. Lastly, exposure to violence was associated with higher experienced, internalized, perceived community stigma and disclosure concerns. These risk factors can be targeted when developing stigma-prevention interventions.

Condom Use Behaviors, Risk Perception, and Partner Communication Following Oral HIV Self-testing Among Adolescents and Young Adults in Kenya: A Cohort Study.

HIV self-testing (HIVST) can improve testing completion among adolescents and young adults (AYA), although its influence on sexual behaviors is unclear. We evaluated whether HIVST was associated with changes in talking with sexual partners about HIVST, condom use, and HIV risk perception among AYA ages 15-24 years in a study of HIVST distribution through homes, pharmacies, and nightclubs in Nairobi, Kenya. All participants had negative HIVST results. Regression models were used to evaluate changes between pre-HIVST and 4 months post-HIVST. Overall, there was a significant increase in talking with sexual partners about HIVST. There was a significant reduction in number of condomless sex acts among AYA recruited through pharmacies and homes. Unexpectedly, among females, there was a significant decrease in consistent condom use with casual partners. HIVST services for AYA may benefit from including strategies to support condom use and partner communication about self-testing adapted to specific populations and partnerships.

"Whenever you need support, you first turn to the group": motivations and functions of WhatsApp groups for youth living with HIV.

Social support is a critical component of achieving positive health outcomes for youth living with HIV (YLWH). Mobile health (mHealth) has significant potential for providing social support to YLWH. However, little is known about the domains of social support most needed by YLWH which mHealth interventions might address. Drawing on the spontaneous creation of WhatsApp support groups by YLWH in Nairobi, Kenya, we characterized Kenyan YLWH's social support needs and potential roles of social media groups in meeting them. We conducted interviews and focus-groups with 68 YLWH, 24 caregivers and 20 healthcare workers, and observed two YLWH-led WhatsApp groups for 6 weeks. Youth reported that existing support systems, including family and healthcare workers, already provided informational and instrumental support. However, they emphasized unmet companionship and emotional support needs, leading to isolation, hopelessness, and medication adherence challenges. Participants identified connection with other YLWH as a unique source of emotional and companionship support that allowed them to feel more secure and less isolated. Interviews and observed WhatsApp chats demonstrated that WhatsApp groups were a desirable medium for companionship support that overcame barriers to in-person connection.

"When they are all grown, I will tell them": Experience and perceptions of parental self-disclosure of HIV status to children in Nairobi, Kenya.

BACKGROUND: There is mixed evidence on the influence of self-disclosure of one's HIV status on mental health, health behaviours and clinical outcomes. We studied the patterns of self-disclosure among parents living with HIV, and factors that influence parental disclosure. METHODS: This mixed-methods study was among adults in HIV care participating in a study assessing the uptake of pediatric index-case testing. They completed a survey to provide demographic and HIV-related health information, and assess self-disclosure to partners, children and others. We ran generalized linear models to determine factors associated with disclosure and reported prevalence ratios (PR). Eighteen participants also participated in in-depth interviews to explore perceived barriers and facilitators of self-disclosure to one's child. A content analysis approach was used to analyze interview transcripts. RESULTS: Of 493 caregivers, 238 (48%) had a child ≥ 6 years old who could potentially be disclosed to about their parent's HIV status. Of 238 participants, 205 (86%) were female, median age was 35 years, and 132 (55%) were in a stable relationship. Among those in a stable relationship, 96 (73%) knew their partner's HIV status, with 79 (60%) reporting that their partner was living with HIV. Caregivers had known their HIV status for a median 2 years, and the median age of their oldest child was 11 years old. Older caregiver age and older first born child's age were each associated with 10% higher likelihood of having disclosed to a child (PR: 1.10 [1.06-1.13] and PR: 1.10 [1.06-1.15], per year of age, respectively). The child's age or perceived maturity and fear of causing anxiety to the child inhibited disclosure. Child's sexual activity was a motivator for disclosure, as well as the belief that disclosing was the "right thing to do". Caregivers advocated for peer and counseling support to gain insight on appropriate ways to disclose their status. CONCLUSIONS: Child's age is a key consideration for parents to disclose their own HIV status to their children. While parents were open to disclosing their HIV status to their children, there is a need to address barriers including anticipated stigma, and fear that disclosure will cause distress to their children.

Comparable Pregnancy Outcomes for HIV-Uninfected and HIV-Infected Women on Antiretroviral Treatment in Kenya.

BACKGROUND: The impact of human immunodeficiency virus (HIV) on pregnancy outcomes for women on antiretroviral therapy (ART) in sub-Saharan Africa remains unclear. METHODS: Pregnant women in Kenya were enrolled in the second trimester and followed up to delivery. We estimated effects of treated HIV with 3 pregnancy outcomes: loss, premature birth, and low birth weight and factors associated with HIV-positive status. RESULTS: Of 2113 participants, 311 (15%) were HIV infected and on ART. Ninety-one of 1762 (5%) experienced a pregnancy loss, 169/1725 (10%) a premature birth (<37 weeks), and 74/1317 (6%) had a low-birth-weight newborn (<2500 g). There was no evidence of associations between treated HIV infection and pregnancy loss (adjusted relative risk [aRR], 1.19; 95% confidence interval [CI], .65-2.16; P = .57), prematurity (aRR, 1.09; 95% CI, .70-1.70; P = .69), and low birth weight (aRR, 1.36; 95% CI, .77-2.40; P = .27). Factors associated with an HIV-positive status included older age, food insecurity, lower education level, higher parity, lower gestation at first antenatal clinic, anemia, and syphilis. Women who were overweight or underweight were less likely to be HIV infected compared to those with normal weight. CONCLUSIONS: Currently treated HIV was not significantly associated with adverse pregnancy outcomes. HIV-infected women, however, had a higher prevalence of other factors associated with adverse pregnancy outcomes.

Prevalence of microcephaly and Zika virus infection in a pregnancy cohort in Kenya, 2017-2019.

BACKGROUND: Zika virus (ZIKV), first discovered in Uganda in 1947, re-emerged globally in 2013 and was later associated with microcephaly and other birth defects. We determined the incidence of ZIKV infection and its association with adverse pregnancy and fetal outcomes in a pregnancy cohort in Kenya. METHODS: From October 2017 to July 2019, we recruited and followed up women aged ≥ 15 years and ≤ 28 weeks pregnant in three hospitals in coastal Mombasa. Monthly follow-up included risk factor questions and a blood sample collected for ZIKV serology. We collected anthropometric measures (including head circumference), cord blood, venous blood from newborns, and any evidence of birth defects. Microcephaly was defined as a head circumference (HC) < 2 standard deviations (SD) for sex and gestational age. Severe microcephaly was defined as HC < 3 SD for sex and age. We tested sera for anti-ZIKV IgM antibodies using capture enzyme-linked immunosorbent assay (ELISA) and confirmed positives using the plaque reduction neutralization test (PRNT90) for ZIKV and for dengue (DENV) on the samples that were ZIKV neutralizing antibody positive. We collected blood and urine from participants reporting fever or rash for ZIKV testing. RESULTS: Of 2889 pregnant women screened for eligibility, 2312 (80%) were enrolled. Of 1916 recorded deliveries, 1816 (94.6%) were live births and 100 (5.2%) were either stillbirths or spontaneous abortions (< 22 weeks of gestation). Among 1236 newborns with complete anthropometric measures, 11 (0.9%) had microcephaly and 3 (0.2%) had severe microcephaly. A total of 166 (7.2%) participants were positive for anti-ZIKV IgM, 136 of whom became seropositive during follow-up. Among the 166 anti-ZIKV IgM positive, 3 and 18 participants were further seropositive for ZIKV and DENV neutralizing antibodies, respectively. Of these 3 and 18 pregnant women, one and 13 (72.2%) seroconverted with antibodies to ZIKV and DENV, respectively. All 308 samples (serum and urine samples collected during sick visits and samples that were anti-ZIKV IgM positive) tested by RT-PCR were negative for ZIKV. No adverse pregnancy or neonatal outcomes were reported among the three participants with confirmed ZIKV exposure. Among newborns from pregnant women with DENV exposure, four (22.2%) were small for gestational age and one (5.6%) had microcephaly. CONCLUSIONS: The prevalence of severe microcephaly among newborns in coastal Kenya was high relative to published estimates from facility-based studies in Europe and Latin America, but little evidence of ZIKV transmission. There is a need for improved surveillance for microcephaly and other congenital malformations in Kenya.

High Acceptance and Completion of HIV Self-testing Among Diverse Populations of Young People in Kenya Using a Community-Based Distribution Strategy.

Oral HIV self-testing (HIVST) may expand access to testing among hard-to-reach reach adolescents and young adults (AYA). We evaluated community-based HIVST services for AYA in an urban settlement in Kenya. Peer-mobilizers recruited AYA ages 15-24 through homes, bars/clubs, and pharmacies. Participants were offered oral HIVST, optional assistance and post-test counseling. Outcomes were HIVST acceptance and completion (self-report and returned kits). Surveys were given at enrollment, post-testing, and 4 months. Log-binomial regression evaluated HIVST preferences by venue. Among 315 reached, 87% enrolled. HIVST acceptance was higher in bars/clubs (94%) than homes (86%) or pharmacies (75%). HIVST completion was 97%, with one confirmed positive result. Participants wanted future HIVST at multiple locations, include PrEP, and cost ≤ $5USD. Participants from bars/clubs and pharmacies were more likely to prefer unassisted testing and peer-distributers compared to participants from homes. This differentiated community-based HIVST strategy could facilitate engagement in HIV testing and prevention among AYA.

Home-based HIV Testing for Children: A Useful Complement for Caregivers with More Children, Who are Male, and with an HIV Negative Partner.

Expanding index and family-based testing (HBT) is a priority for identifying children living with HIV. Our study characterizes predictors that drive testing location choice for children of parents living with HIV. Kenyan adults living with HIV were offered a choice of HBT or clinic-based testing (CBT) for any of their children (0-12 years) of unknown HIV status. Multilevel generalized linear models were used to identify correlates of choosing HBT or CBT for children and testing all versus some children within a family, including caregiver demographics, HIV history, social support, cost, and child demographics and HIV prevention history. Among 244 caregivers living with HIV and their children of unknown HIV status, most (72%) caregivers tested children using CBT. In multivariate analysis, female caregivers [aRR 0.52 (95% CI 0.34-0.80)] were less likely to choose HBT than male caregivers. Caregivers with more children requiring testing [aRR 1.23 (95% CI 1.05-1.44)] were more likely to choose HBT than those with fewer children requiring testing. In subgroup univariate analysis, female caregivers with a known HIV negative spouse were significantly more likely to choose HBT over CBT than those with a known HIV positive spouse [RR 2.57 (95% CI 1.28-5.14), p = 0.008], no association was found for male caregivers. Child demographics and clinical history was not associated with study outcomes. Caregiver-specific factors were more influential than child-specific factors in caregiver choice of pediatric HIV testing location. Home-based testing may be preferable to families with higher child care needs and may encourage pediatric HIV testing if offered as an alternative to clinic testing.

"It's about making adolescents in charge of their health": policy-makers' perspectives on optimizing the health care transition among adolescents living with HIV in Kenya.

ABSTRACTThe health care transition (HCT) from pediatric to adult care is a potential contributor to poor clinical outcomes among adolescents living with HIV (ALHIV). In sub-Saharan Africa (SSA), there is limited information on effective tools and processes to prepare and support ALHIV through this transition. This study elicited perspectives of policy-makers regarding barriers and facilitators to successful HCT among ALHIV in Kenya. Twenty in-depth interviews (IDIs) were conducted with policy-makers using a semi-structured guide. Using the socio-ecological model (SEM) as an organizing framework, directed content and thematic network analyses methods were used to characterize themes related to key influences on HCT processes and to describe actionable recommendations for improved tools and resources. Policy-makers identified multilevel support, including the development of a triadic relationship between the caregiver, healthcare worker (HCW) and adolescent, as an essential strategy for improved HCT success. Across the SEM, policy-makers described the importance of actively engaging adolescents in their care to promote increased ownership and autonomy over health decisions. At the structural level, the need for more comprehensive HCT guidelines and improved HCW training was highlighted. Expanded HCT tools and guidelines, that emphasize supportive relationships and intensified adolescent engagement, may improve HCT processes and outcomes.

Association of experienced and internalized stigma with self-disclosure of HIV status by youth living with HIV.

We examined patterns of disclosure among youth living with HIV (YLHIV) in Kenya, and the association between self-disclosure and antiretroviral therapy adherence, stigma, depression, resilience, and social support. Of 96 YLHIV, 78% were female, 33% were ages 14-18, and 40% acquired HIV perinatally. Sixty-three (66%) YLHIV had self-disclosed their HIV status; 67% to family and 43% to non-family members. Older YLHIV were 75% more likely to have self-disclosed than those 14-18 years. Of the 68 either married or ever sexually active, 45 (66%) did not disclose to their partners. Those who had self-disclosed were more likely to report internalized stigma (50% vs. 21%, prevalence ratio [PR] 2.3, 1.1-4.6), experienced stigma (26% vs. 3%, PR 11.0, 1.4-86), and elevated depressive symptoms (57% vs. 30%, PR 1.8, 1.0-3.1). The association with stigma was stronger with self-disclosure to family than non-family. Support should be provided to YLHIV during self-disclosure to mitigate psychosocial harms.

What happens at adolescent and young adult HIV clinics? A national survey of models of care, transition and disclosure practices in Kenya.

OBJECTIVE: Tailored services for adolescents and young adults (AYA) living with HIV may improve treatment outcomes. We surveyed HIV clinics throughout Kenya to determine AYA clinic practices, disclosure and transition services. METHODS: We deployed a mobile team to conduct surveys in a random sample of 102 public HIV clinics with> 300 total clients. Data were collected from healthcare workers offering AYA services who had >6 months of experience delivering AYA care. RESULTS: Of 102 surveyed HIV clinics, almost all (101/102) had the same staff to provide services to all age groups. AYA-specific services included dedicated clinic days (91%), the majority being on weekends (57%) and designated clinic spaces (20%). Activities to support AYA retention and adherence were common (support groups [97%] and HIV literacy meetings [93%]). Fewer clinics offered more holistic care, including psychosocial support (16%) and career education (2%), posted additional staff during the AYA day (17%), provided food (17%) or had sporting activities (10%) as incentives. Tracking of disclosure of HIV status to AYA was common (87%). In 40% of clinics, disclosure discussions with caregivers or AYA occurred a median of 2 years later in practice than stated in clinic policy. Transition was not routinely tracked, and definitions were heterogeneous. Median age at transition was reported as 20 years (range: 14-30 years). CONCLUSION: HIV programmes have implemented varied approaches to enhance AYA services that could be leveraged to support transition to adult services. Research on the impact of these services on health outcomes is needed.

OBJECTIF: Des services taillés sur mesure pour les adolescents et les jeunes adultes (AJA) vivant avec le VIH peuvent améliorer les résultats du traitement. Nous avons mené une surveillance des cliniques VIH à travers le Kenya pour déterminer les pratiques, la divulgation et les services de transition dans les cliniques AJA. MÉTHODES: Nous avons déployé une équipe mobile pour mener des enquêtes sur un échantillon aléatoire de 102 cliniques publiques du VIH avec >300 patients au total. Les données ont été recueillies auprès d'agents de santé offrant des services AJA qui avaient >6 mois d'expérience dans la prestation de soins AJA. RÉSULTATS: Sur 102 cliniques VIH surveillées, presque toutes (101/102) avaient les mêmes personnels pour fournir des services à tous les groupes d'âge. Les services spécifiques AJA comprenaient des journées de clinique dédiées (91%), la majorité étant le week-end (57%) et des espaces de clinique désignés (20%). Les activités visant à soutenir la rétention et l'adhésion à l'AJA étaient courantes (groupes de soutien [97%] et réunions d'éducation sur le VIH [93%]). Peu de cliniques offraient de soins plus holistiques, y compris un soutien psychosocial (16%) et une formation professionnelle (2%), détachaient du personnel supplémentaire pendant la journée AJA (17%), fournissait de la nourriture (17%) ou pratiquaient des activités sportives (10%) comme des incitations. Le suivi de la divulgation du statut VIH aux AJA était courant (87%). Dans 40% des cliniques, les discussions de divulgation avec les soignants ou AJA ont eu lieu en moyenne 2 ans plus tard dans la pratique que ce qui est indiqué dans la politique de la clinique. La transition n'était pas systématiquement suivie et les définitions étaient hétérogènes. L'âge médian au moment de la transition était de 20 ans (intervalle: 14-30 ans). CONCLUSION: Les programmes de lutte contre le VIH ont mis en œuvre diverses approches pour améliorer les services AJA qui pourraient être exploitées pour soutenir la transition vers les services pour adultes. Des recherches sur l'impact de ces services sur les résultats de santé sont nécessaires.

Newly diagnosed HIV positive children: a unique index case to improve HIV diagnosis and linkage to care of parents.

Newly diagnosed HIV positive children may be unique index cases to identify undiagnosed parents. Data was used from the Pediatric Urgent Start of HAART (NCT02063880) trial, which enrolled hospitalized, ART-naïve, HIV positive children ages 0-12 years in Kenya. Exact McNemar's tests were used to compare proportions of mothers and fathers tested for HIV, linked to care, and on ART at baseline and 6 months. This analysis included 87 newly diagnosed children with HIV who completed 6 months of follow-up. Among 83 children with living mothers, there were improvements in maternal linkage to care and treatment comparing baseline to 6 months (36% vs. 78%; p < 0.0001 and 22% vs. 52%; p < 0.0001). Among 80 children with living fathers, there were increases from baseline to 6 months in the number of fathers who knew the child's HIV status (34% vs. 78%; p < 0.0001), fathers ever tested for HIV (43% vs. 65%; p < 0.0001), fathers ever tested HIV positive (21% vs. 43%; p < 0.0001), fathers ever linked to care (15% vs. 35%; p < 0.0001), and fathers ever initiated on ART (11% vs. 23%; p = 0.0039). Newly diagnosed HIV positive children can be important index cases to identify parents with undiagnosed HIV or poor engagement in care.

Managing the transition from paediatric to adult care for HIV, Kenya.

Expansion of access to diagnosis and treatment for human immunodeficiency virus (HIV) and a high incidence of HIV infection in adolescence has resulted in a growing population of adolescents and young adults living with HIV. The prevalence of poor retention in care, insufficient viral suppression and loss to follow-up are higher among adolescents and young adults compared with other age groups. Poor outcomes could be attributed to psychosocial changes during adolescence, but also to poor transitional care from paediatric to adult HIV services. In many countries, transition processes remain poorly defined and unstructured, which may jeopardize treatment adherence and retention. We describe existing definitions of transition and transition frameworks, and key elements of transition as proposed by key national stakeholders in Kenya. Our consensus definition of transition is "a planned process by which adolescents and young adults living with HIV, and their caregivers, are empowered with knowledge and skills to enable them to independently manage their health." Transition should begin soon after disclosure of HIV status until an adolescent gains the necessary knowledge and skills and is willing to move to adult services, or by 25 years of age. Proposed key elements of transition are: target ages for milestone achievement; readiness assessment; caregiver involvement and communication with adult clinics; flexibility to return to adolescent or paediatric clinics; group transition; and considerations for adolescents with special needs. Retention in care, linkage to care and viral suppression are important markers of transition success. Proposed definitions and key elements could provide a framework for structuring transition programmes in other countries.

L'accès élargi au diagnostic et au traitement du virus de l'immunodéficience humaine (VIH) et l'incidence élevée de l'infection par le VIH à l'adolescence ont entraîné une hausse de la population d'adolescents et de jeunes adultes atteints du VIH. La prévalence de mauvais continuums de soins, de suppressions virales insuffisantes et d'interruptions du suivi est plus élevée chez les adolescents et les jeunes adultes que dans d'autres groupes d'âge. Ces mauvais résultats peuvent être attribués aux changements psychosociaux qui interviennent à l'adolescence, mais aussi à la médiocrité de la transition entre les services de soins pédiatriques et adultes du VIH. En Afrique subsaharienne, les processus de transition sont mal définis et peu structurés, ce qui peut nuire au respect et à la poursuite des traitements. Nous décrivons ici les définitions existantes de la transition et des cadres de transition, ainsi que les éléments clés de la transition proposés par les principales parties prenantes nationales du Kenya. Notre définition consensuelle de la transition est: « processus planifié qui permet aux adolescents et aux jeunes adultes atteints du VIH, ainsi qu'à leurs aidants, de disposer des connaissances et compétences nécessaires pour gérer leur santé de manière autonome ¼. La transition devrait débuter peu après la communication de la séropositivité et durer jusqu'à ce que l'adolescent ait acquis les connaissances et compétences nécessaires et qu'il souhaite passer à des services pour adultes, ou jusqu'à l'âge de 25 ans. Les éléments clés proposés de la transition sont: âges cibles pour le franchissement de certaines étapes; évaluation de la maturité; implication des aidants et communication avec les services pour adultes; possibilité de revenir à des services pédiatriques ou pour adolescents; transition de groupe; prise en compte des adolescents ayant des besoins spéciaux. Le continuum de soins, le lien entre les soins et la suppression virale sont d'importants marqueurs de la réussite de la transition. Les définitions et éléments clés proposés peuvent offrir un cadre pour structurer les programmes de transition dans d'autres pays.

La ampliación del acceso al diagnóstico y tratamiento del virus de la inmunodeficiencia humana (VIH) y la alta incidencia de la infección por el VIH en la adolescencia han dado lugar a una población creciente de adolescentes y adultos jóvenes que viven con el VIH. La prevalencia de una retención inadecuada en la atención, la supresión viral insuficiente y la pérdida de seguimiento son mayores entre los adolescentes y los adultos jóvenes en comparación con otros grupos de edad. Los resultados negativos pueden atribuirse a cambios psicosociales durante la adolescencia, pero también a una atención de transición deficiente de los servicios pediátricos a los servicios para adultos con VIH. En África subsahariana, los procesos de transición siguen siendo mal definidos y desestructurados, lo que puede suponer un riesgo para el cumplimiento y la retención del tratamiento. Describimos las definiciones existentes de transición y los marcos de transición, así como los elementos clave de la transición propuestos por las principales partes interesadas a nivel nacional en Kenia. Nuestra definición consensuada de transición es "un proceso planificado mediante el cual los adolescentes y adultos jóvenes que viven con el VIH, y sus cuidadores, son capacitados con conocimientos y habilidades que les permiten manejar su salud de manera independiente". La transición debe comenzar poco después de la revelación del estado serológico respecto al VIH hasta que el adolescente adquiera el conocimiento y las habilidades necesarias y esté dispuesto a trasladarse a los servicios para adultos, o a la edad de 25 años. Los elementos clave de la transición propuestos son: edades objetivo para el logro de los hitos; evaluación de la preparación; participación de los cuidadores y comunicación con las clínicas para adultos; flexibilidad para regresar a las clínicas para adolescentes o pediátricas; transición de grupos; y consideraciones para los adolescentes con necesidades especiales. La retención en la atención, la vinculación a la atención y la supresión viral son marcadores importantes del éxito de la transición. Las definiciones propuestas y los elementos clave podrían proporcionar un marco para estructurar los programas de transición en otros países.

Influence and involvement of support people in adolescent and young adult HIV testing.

HIV incidence and mortality are high among adolescents and young adults (AYA) in sub-Saharan Africa, but testing rates are low. Understanding how support people (SP), such as peers, partners, or parents, influence AYA may improve HIV testing uptake. AYA aged 14-24 seeking HIV testing at a referral hospital in Nairobi, Kenya completed a post-test survey assessing the role of SP. Among 1062 AYA, median age was 21. Overall, 12% reported their decision to test was influenced by a parent, 20% by a partner, and 22% by a peer. Young adults (20-24 years old) were more likely than adolescents (14-19 years old) to be influenced to test by partners (23% vs. 12%, p < .001), and less likely by parents (6.6% vs. 27%, p < .001), healthcare workers (11% vs. 16%, p < .05), or counselors (9.4% vs. 19%, p < .001). Half of AYA were accompanied for testing (9.9% with parent, 10% partner, 23% peer, 4.3% others, and 2.1% multiple types). Young adults were more likely than adolescents to present alone (58% vs. 32%, p < .001) or with a partner (12% vs. 6.7%, p < .05), and less likely with a parent (1.6% vs. 31%, p < .001). Similar proportions of adolescents and young adults came with a peer or in a group. Correlates of presenting with SP included: younger age (aRR = 1.55 [95%CI = 1.30-1.85]), female sex (aRR = 1.45 [95%CI = 1.21-1.73]), and school enrollment (aRR = 1.41 [95%CI = 1.05-1.88]). SP play an important role in AYAs' HIV testing and varies with age. Leveraging SP may promote uptake of HIV testing and subsequent linkage care for AYA.

Pilot evaluation of a standardized patient actor training intervention to improve HIV care for adolescents and young adults in Kenya.

Poor retention in HIV care remains a major problem for Adolescents and Young Adults (AYA). A Standardized Patient (SP) clinical training intervention was developed to improve healthcare worker (HCW) "adolescent-friendly" competencies in Kenya. Professional actors were trained to portray HIV-infected AYA according to standardized scripts. HCWs completed a 2-day SP training that included didactic sessions, 7 video-recorded SP encounters, and group debriefing. AYA health experts rated HCWs by reviewing the video recordings. All HCWs (10/10) reported high satisfaction with the intervention and overall improvement in self-rated competency in caring for HIV-infected AYA. Cases were reported to be realistic and relevant by between 7 and 10 of 10 HCWs. The case on disclosure and adherence was rated as most challenging in communication and making medical decisions by HCWs. Areas identified by SPs for improvement by HCWs included allowing patients time to ask questions, and enabling SP to share sensitive information. The overall ICC by experts was low 0.27 (95% CI: -0.79 to 0.95), however, ICCs in assessment of HIV disclosure 0.78 (95% CI: 0.17-0.98), and sexual behavior 0.97 (95% CI: 0.89-0.99) were high. This intervention was acceptable for Kenyan HCWs and improved self-rated competency in caring for HIV-infected AYA.
