Neurocognitive outcomes of children exposed to and living with HIV aged 3-5 years in Kilifi, Kenya. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1193183. [PMID: 37732169 PMCID: PMC10508958 DOI: 10.3389/frph.2023.1193183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Accepted: 08/14/2023] [Indexed: 09/22/2023] Open
Abstract
Introduction Globally, 1.7 million children are living with HIV, with the majority of them residing in sub-Saharan Africa. Due to reduced rates of vertical transmission of HIV, there is an increasing population of children born to HIV-infected mothers who remain uninfected. There is a growing concern around the development of these children in the antiretroviral therapy era. This study examined the neurocognitive outcomes of children who are HIV-exposed infected (CHEI), HIV-exposed uninfected (CHEU) and HIV-unexposed uninfected (CHUU) and explored the relationship between child neurocognitive outcomes and child's biomedical and caregivers' psychosocial factors. Methods CHEI, CHUU and CHEU aged 3-5 years and their caregivers were recruited into the study. Neurocognitive outcomes were assessed using a validated battery of assessments. One-way analysis of variance and covariance (ANOVA and ANCOVA) were used to evaluate differences among the three groups by neurocognitive outcomes. Linear regression models were used to investigate the association between child neurocognitive outcomes and biomedical factors (nutritional status, HIV disease staging) and caregivers' psychosocial factors [symptoms of common mental disorders (CMDs) and parenting behaviour]. Results The study included 153 children and their caregivers: 43 (28.1%) CHEI, 52 (34.0%) CHEU and 58 (39.9%) CHUU. ANOVA and ANCOVA revealed a significant difference in cognitive ability mean scores across the child groups. Post hoc analysis indicated that CHEU children had higher cognitive ability mean scores than the CHUU group. Better nutritional status was significantly associated with higher cognitive ability scores (β = 0.68, 95% CI [0.18-1.18], p = 0.008). Higher scores of CMDs were negatively associated with inhibitory control (β = -0.28, 95% CI [-0.53 to 0.02], p = 0.036). While comparing HIV stages 2 and 3, large effect sizes were seen in working memory (0.96, CI [0.08-1.80]) and cognitive ability scores (0.83 CI [0.01-1.63]), indicating those in stage 3 had poor performance. Conclusions Neurocognitive outcomes were similar across CHEI, CHEU and CHUU, although subtle differences were seen in cognitive ability scores where CHEU had significantly higher cognitive mean scores than the CHUU. Well-designed longitudinal studies are needed to ascertain these findings. Nonetheless, study findings underscore the need for strategies to promote better child nutrition, mental health, and early antiretroviral therapy initiation.

SOUTH AFRICAN JOURNAL OF COMMUNICATION DISORDERS 2022; 69:e1-e10.

Abstract
BACKGROUND Severe acute malnutrition (SAM) is associated with cognitive and motor deficits. Little is known about the swallowing, feeding and communication characteristics of hospitalised toddlers with SAM, limiting the abilities of speech-language therapists to provide effective early intervention. OBJECTIVE To explore the background, swallowing, feeding and communication characteristics of toddlers with SAM during in-patient nutritional rehabilitation. METHOD An exploratory, prospective, collective case-study was conducted with three hospitalised toddlers who were 12-18 months old and independently diagnosed with SAM, at least 1 week after transitioning to oral feeding. Detailed case histories were compiled through medical file perusal and parent interviews. Cross-sectional clinical bedside assessments were completed with the Rossetti Infant-Toddler Language Scale and Schedule for Oral-Motor Assessment. RESULTS All three participants had a history of feeding difficulties before admission. Despite intact pharyngeal swallows, heterogeneous oral-sensorimotor dysfunction and disruptive feeding behaviours were identified. Risk for oropharyngeal dysphagia indicates the need to modify dietary consistencies to prevent prolonging recovery or SAM relapse. Participants had mild-to-moderate language delays, particularly in interaction-attachment, play and language comprehension, with an atypical moderate receptive and mild expressive language delay profile. None of the participants were referred for speech-language therapy. CONCLUSION This exploratory research showed the oral-sensorimotor skills, swallowing and communication characteristics of children with SAM. Speech-language therapists could address oral-sensorimotor functioning, feeding difficulties and communication interaction delays before discharge to community-based management for SAM. Further investigation with a larger sample size is recommended.Contribution: Novel description of the oral-sensorimotor skills for feeding and the communication development of three severely malnourished toddlers with HIV and tuberculosis co-infection was presented. The complexity of the three cases is highlighted.

Abstract
BACKGROUND HIV-exposed but uninfected (HEU) infants are at increased risk of impaired early linear growth and cognitive development. We examined associations between prenatal and postnatal growth and subsequent neurodevelopment in Ugandan HEU infants, hypothesizing that early insults may explain alterations in both somatic growth and brain development. METHODS We prospectively followed a cohort of HEU infants from birth to 18 months of age, and measured length/height, weight, head, and arm circumference longitudinally. The Malawi Development Assessment Tool (MDAT, 12 and 18 months) and the Color Object Association Test (18 months) were used for developmental assessments. RESULTS Among 170 HEU infants, the prevalence of low-birth weight and failure to thrive was 7.6% and 37%, respectively. HEU infants had MDAT scores that were similar to the reference population. The mean (SD) score on the Color Object Association Test was 5.5 (3.1) compared with 6.9 (5.3) in developmentally normal children. Developmental ability at age 18 months showed strong cross-sectional correlation with weight-for-age (ρ = 0.36, P < 0.0001), length/height-for-age (ρ = 0.41, P < 0.0001), head circumference-for-age (ρ = 0.26, P = 0.0011), and mid-upper arm circumference-for-age (ρ = 0.34, P = 0.0014). There was a statistically significant correlation between birth weight and MDAT z-score at 18 months (ρ = 0.20, P = 0.010). Failure to thrive was associated with lower MDAT z-score [median -0.13 (IQR -0.75 to +0.14) versus +0.14 (IQR -0.44 to +0.63), P = 0.042]. CONCLUSION Growth faltering in HEU infants was associated with lower attainment of developmental milestones at age 18 months. Our findings point to a simple screening method for identifying HEU infants at risk for developmental intervention.

Abstract
This paper aimed to assess the impact of maternal common mental disorders (CMD) among caregivers living with HIV on the cognitive functioning of their child. Data were collected at baseline and 12 months follow-up from mother-child dyads recruited as part of an ongoing trial in Zimbabwe. Symptoms of CMD were assessed using the Shona Symptom Questionnaire. Mixed-effects linear regression was used to assess child cognitive scores at follow-up (using the Mullen Scales of Early Learning) in relation to caregiver CMD prevalence over 12 months. At baseline, caregivers reporting CMD (n = 230; 40.1%) were less likely to have completed higher education (46.9% vs. 56.9%; p = 0.02), more likely to be unmarried (27.8% vs. 16.0%; p < 0.01), and experience food insecurity (50.0% vs. 29.4%; p < 0.01) compared to the group without CMD (n = 344). There were 4 CMD patterns over time: (i) Emerging CMD (n = 101; 19.7% of caregivers) defined as those who were below the cut-off at baseline, and above it at 12 months; (ii) Improving CMD (n = 76; 14.8%) defined as those who reported CMD at baseline, and were below the cut-off by follow-up; (iii) No CMD (n = 206; 40.1%) defined as those who did not report CMD symptoms at either time point; and (iv) Chronic CMD (n = 131; 25.5%) defined as those who reported CMD above the cut-off at both time points. Children of caregivers with chronic CMD (n = 131, 25.5%) had lower receptive language scores (aMD:-2.81, 95%CI -5.1 to -0.6; p = 0.05) compared to the reference group with no CMD (n = 206, 40.1%). Exposure to caregiver CMD over a prolonged period may affect child receptive vocabulary skills.

Abstract
OBJECTIVE We sought to evaluate whether maternal characteristics and infant developmental milieu were predictive of early cognitive development in HIV-exposed uninfected (HEU) and HIV-unexposed uninfected (HU) infants in Uganda. DESIGN Longitudinal pregnancy study. METHODS Ugandan women (n = 228) were enrolled into the Postnatal Nutrition and Psychosocial Health Outcomes study with a 2:1 HIV-uninfected: infected ratio. Maternal sociodemographic, perceived social support, and depressive symptomatology were assessed. Infant growth and neurocognitive development were assessed at 6 and 12 months of age using Mullen Scales of Early Learning (MSEL). Caldwell Home Observation for Home Environment was used to gauge caregiving quality. Linear mixed-effects models were built to examine the relationships between maternal and infant characteristics with infant MSEL scores by HIV exposure. RESULTS Two MSEL measures were available for 215 mother-child dyads: 140 infants (65%) were HIV-uninfected (HU), 57 (27%) were HIV-exposed uninfected (HEU) with mothers reporting antiretroviral therapy, and 18 (8%) were HEU with mothers not reporting antiretroviral therapy. HEU had lower MSEL Composite (β = -3.94, P = 0.03) and Gross Motor scores (β = -3.41, P = 0.01) than HU. Home Observation for Home Environment total score was positively associated with MSEL Composite (β = 0.81, P = 0.01), Receptive Language (β = 0.59, P = 0.001), and Expressive Language (β = 0.64, P = 0.01) scores. CONCLUSIONS HIV exposure is associated with lower infant cognitive development scores. Increasing maternal quality of caregiving may improve early cognitive development.

Abstract
OBJECTIVE HIV infection is associated with cognitive impairments, but outcomes are poorly explored in children starting antiretroviral therapy (ART) early or in those exposed but uninfected. DESIGN Nested cross-sectional evaluation of the neurocognitive and behavioural outcomes of HIV-infected, HIV-exposed uninfected (HEU) and HIV-unexposed (HUU) Cameroonian children at age 4-9 years prospectively followed. METHODS Cognitive development was assessed in 127 HIV-infected, 101 HEU, 110 HUU children using the KABC-II, neurologic dysfunction using the Touwen examination and behavioural difficulties using the Strength and Difficulties Questionnaire (SDQ). Analyses were adjusted for children age, sex and primary language. Contextual factors were included in a second step to assess their effects on outcomes. RESULTS All HIV-infected children were treated before 12 months. There was a negative linear gradient in KABC-II scores from HUU children to HEU and HIV-infected children [gradient: -6.0 (-7.7; -4.3) for nonverbal index, NVI, and -8.8 (-10.7; -6.8) for mental processing index, MPI]. After adjusting for contextual factors, scores of HEU children were not significantly different from those of HUU children (all P > 0.1) and differences between HIV-uninfected and HUU children reduced [NVI: from -11.9 (-15.3; -8.5) to -3.4 (-6.8; -0.01), MPI: from -17.6 (-21.3; -13.8) to -5.5 (-9.3; -1.7)]. Compared with uninfected children, HIV-infected children had more neurological dysfunctions and higher SDQ scores (P = 0.002). CONCLUSION Despite early ART, perinatal-HIV infection is associated with poorer neurocognitive scores and increased behavioural difficulties during childhood. Contextual factors play an important role in this association, which emphasizes the need for early nutritional and developmental interventions targeting both HIV-affected infants and their relatives.

Abstract
This study examines the cognitive profiles of infants born to HIV positive mothers in Zimbabwe. Caregivers with HIV exposed infants delivered in 30 clinics in two areas of Zimbabwe were recruited to the study. Of the 574 study participants, 562 caregiver-infant dyads with a biological HIV +ve mother and infant aged 0-24 months were interviewed. All infants were tested by a trained administrator for cognitive development on the Mullen Scales of Early Learning (MSEL). The Edinburgh Postnatal Depression Scale and Parental Stress Index-Short Form were completed by the mothers together with infant and caregiver socioeconomic characteristics. Linear regression models were used to relate cognitive development scores to maternal stress scores, maternal depression scores and infant HIV status adjusting for infant and caregiver characteristics, as well as socioeconomic factors. Higher maternal depression scores were associated with lower overall infant cognitive scores (adjusted mean difference (aMD) = -0.28; CI 95%:-0.50 to -0.06; p = 0.01) and in the expressive language (aMD = -0.14; CI 95%:-0.27 to -0.01; p = 0.04), fine motor skills (aMD = -0.17; CI 95%: -0.33 to -0.01; p = 0.03), gross motor (aMD = -0.22; CI 95%:-0.40 to -0.04; p = 0.02), and visual reception (aMD = -0.22; CI 95%:-0.40 to -0.05; p = 0.01) domains. Higher maternal stress was associated with poorer overall infant cognitive scores (aMD = -0.11; CI 95%:-0.20 to -0.02; p = 0.02) and in the specific domains of expressive language (aMD = -0.07; CI 95%:-0.12 to -0.01; p = 0.01), gross motor skills (aMD = -0.12; CI 95%:-0.18 to -0.05; p < 0.01) and visual reception (aMD = -0.09; CI 95%:-0.16 to -0.02; p = 0.02). Comparisons between the small number of HIV positive infants (n = 16) and the HEU infants (n = 381) showed the latter to have higher mean gross motor scores (50.3 vs. 40.6; p = 0.01). There was no evidence of difference by HIV status in the other MSEL domains or overall mean cognitive scores. Our findings demonstrate the association between maternal mood and stress levels and child cognitive functioning, particularly in expressive language and visual reception development. Although cross sectional data cannot shed light on the direction of this association, the study suggests that interventions to address maternal stress and depression symptoms may prove to be beneficial.

Abstract
BACKGROUND Practical ways are needed to scale-up pediatric HIV testing in sub-Saharan Africa, where testing is usually limited to HIV-exposed children in maternal and child health clinics. METHODS We implemented an enhanced pediatric HIV testing program in 33 health facilities in Zimbabwe by integrating HIV testing into all pediatric health services. We collected individual data on children tested by having health care workers complete a program-specific child health booklet. We compared numbers of children tested before and during the program using routinely collected aggregate program data reported by health facilities. RESULTS A total of 12,556 children aged 0-5 years were recorded in child health booklets; 9431 (75.1%) had information on HIV testing, of whom 7326 (77.7%) were tested; 7167 had test results of whom 122 (1.7%) were HIV-infected. Among children seen in outpatient clinics, 82.1% were tested compared with 66.5% tested among children seen in maternal/child health clinics. Of the 122 HIV-infected children identified, 77 (63.1%) could be missed under existing pediatric testing guidelines. The number of HIV-infected children identified during the 6-month program increased by 55% compared with the prior 6-month period (RR = 1.55, 95% CI: 1.22 to 1.96). Factors independently associated with HIV infection included being malnourished (adjusted odds ratio [AOR] = 7.7, 95% CI: 2.1 to 28.6), being exposed to TB (AOR = 8.1, 95% CI: 2.0 to 32.2), and having an HIV-infected mother (AOR = 41.6, 95% CI: 15.9 to 108.8). CONCLUSIONS Integrating HIV testing into all pediatric health services is feasible and can assist in identifying HIV-infected children who could be missed in current testing guidelines.

Abstract
Objective To identify the incidence of and predictors for tuberculosis in children living with HIV in Northern Ethiopia. Design Observational, retrospective follow-up study. Methods A total of 645 HIV-infected children were observed between September 2009 and September 2014. Cox regression analysis was used to identify predictors for developing TB. Results The incidence rate of tuberculosis was 4.2 per 100 child-years. Incidence of tuberculosis was higher for subjects who were not on cotrimoxazole preventive therapy, were not on isoniazid preventive therapy, had delayed motor development, had a CD4 cell count below the threshold, had hemoglobin level less than 10 mg/dl and were assessed as World Health Organization (WHO) clinical stage III or IV. Conclusion Incidence of TB in children living with HIV was high. This study reaffirmed that isoniazid preventive therapy is one of the best strategy to reduce incidence of TB in children living with HIV. All children living with HIV should be screened for TB but for children with delayed motor development, advanced WHO clinical stage, anemia or immune suppression, intensified screening is highly recommended.
