Neurodevelopment in early treated HIV-infected infants participating in a developmental stimulation programme compared with controls.

BACKGROUND: Neurodevelopmental stimulation programmes can improve developmental outcomes. Antiretroviral therapy (ART) started soon after birth potentially limits the invasion of HIV into the central nervous system. A combination of developmental stimulation and early ART initiation may reduce developmental delays in children with perinatally acquired HIV infection. METHODS: At a single site in Johannesburg, South Africa, we enrolled 36 HIV-infected neonates on ART into an intervention group (IG) participating in a yearlong home-based, neurodevelopmental stimulation programme. Bayley Scales of Infant and Toddler Development-3rd Edition (BSID-III) assessments were conducted at 12 months. Scores were compared with 24 early treated HIV-infected infants in an observational group (OG). BSID-III assessments were also conducted for older children in an OG at 24 or 36 months. Cognitive, language and motor scaled and composite scores were analysed. RESULTS: BSID-III scaled and composite scores were all higher in the IG apart from the gross motor scaled score (9.25 vs. 10, p = 0.1954). Receptive communication scaled score was significantly higher in the IG (10.96 vs. 9, p = 0.0331). IG composite scores were all higher than OG scores. OG children assessed at 24 or 36 months had lower composite scores in all subscales than 12-month OG scores. CONCLUSIONS: Early treated HIV-infected children participating in a neurodevelopmental stimulation programme achieved higher BSID-III scores at 12 months compared with early treated HIV-infected children who did not receive the programme.

A description of early neurodevelopment in a cohort of HIV-exposed uninfected children.

Introduction: Successful strategies preventing mother-to-child HIV transmission have resulted in increasing numbers of uninfected children exposed to maternal HIV and ART in-utero, and while breastfeeding. Some reports describe exposure as impacting neurodevelopment. Methods: This cross-sectional analysis included 49 of the 70 HIV-exposed uninfected (HEU) birth-enrolled children as the control arm of an observational cohort study of early treatment in HIV-infected infants in Johannesburg, South Africa. We used the Bayley Scales of Infant and Toddler Development-3rd Edition (BSID-III) to assess neurodevelopment at 12 months of age. Cognitive, language and motor subscale composite scores and performance categories were analysed. We evaluated associations between BSID-III performance categories and cohort variables. Results: Evaluating composite scores according to performance categories showed a higher percentage of scores in the average, high average and superior categories as compared to test reference norms. Maternal BMI ≥ 25 kg/m2 and mid-upper arm circumference ≥ 32 cm were associated with higher than average infant language scores. Six children scored below average (<90) - three in the cognitive and three in the language subscale. Conclusion: No developmental delay was found in ART-exposed HEU children at 12 months of age. A small number of at-risk children suggest ongoing screening, referral and follow-up is needed.

The effect of the Hambisela programme on stress levels and quality of life of primary caregivers of children with cerebral palsy: A pilot study.

BACKGROUND: Caregivers of children with cerebral palsy (CP) are at risk of having high stress levels and poor quality of life (QOL) which could have a detrimental effect on themselves and their children. Taking caregivers' well-being into consideration is therefore important when providing rehabilitation to children with CP. Interventions to mediate primary caregiver stress and QOL using an educational tool have not been tested in this population in South Africa. OBJECTIVES: The aim of this study was to determine the effect of a group-based educational intervention, Hambisela, on stress levels and QOL of primary caregivers of children with CP in Mamelodi, a township in Gauteng, South Africa. METHOD: Eighteen primary caregivers of children with CP participated in a quasi-experimental pretest-post-test pilot study. Hambisela, a group-based educational intervention, was carried out once a week over 8 consecutive weeks. Caregiver stress and QOL were assessed before and after the intervention using the Parenting Stress Index-Short Form (PSI-SF) and the Paediatric Quality of Life-Family Impact Module (PedsQLTM-FIM). Sociodemographic information was assessed using a demographic questionnaire. The Gross Motor Function Classification System (GMFCS) was used to assess the gross motor level of severity of CP in the children. RESULTS: Data were collected for 18 participants at baseline and 16 participants at follow-up. At baseline, 14 (87.5%) participants had clinically significant stress which reduced to 11 (68.8%) at follow-up. There was no significant change in primary caregiver's stress levels (p = 0.72) and QOL (p = 0.85) after the Hambisela programme. Higher levels of education were moderately associated with lower levels of primary caregiver stress (r = -0.50; p = 0.03). CONCLUSION: Most primary caregivers in this pilot study suffered from clinically significant stress levels. Hambisela, as an educational intervention, was not effective in reducing the stress or improving the QOL in these primary caregivers of children with CP. Future studies with a larger sample size are needed to investigate the high stress levels of primary caregivers of children with CP. CLINICAL IMPLICATIONS: Rehabilitation services for children with disabilities should include assessments to identify caregivers with high stress levels. Holistic management programmes should also include care for the carers.

Neurodevelopmental assessment of HIV-exposed uninfected and early-treated HIV-infected children: study protocol.

OBJECTIVE: Sub-Saharan Africa has the highest prevalence of children at risk of not achieving their developmental potential, attributable largely to the human immunodeficiency virus (HIV) pandemic coupled with negative environmental factors. Childhood developmental stimulation programmes can mitigate adverse outcomes. METHODS: Neonates testing HIV positive at birth will be initiated on antiretroviral treatment (ART) and receive an age-appropriate stimulation program, updated at 3 monthly intervals through the first year of life. Neurodevelopment at 12 months of age will be assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III). Outcomes will be compared with HIV-infected and HIV-exposed uninfected children (HEU) not having received the stimulatory intervention. Associations between neurodevelopmental outcomes, environmental factors, and parental stress will be investigated. The study will take place at a single site in Johannesburg, South Africa. This non-randomised controlled intervention study, with a single non-blinded comparative intervention group, aims to investigate whether an early childhood stimulation programme used in conjunction with ART initiated at birth can positively impact neurodevelopmental outcomes at 1 year of age in children infected with HIV.
