Similar cortical morphometry trajectories from 5 to 9 years in children with perinatal HIV who started treatment before age 2 years and uninfected controls

BACKGROUND

Life-long early ART (started before age 2 years), often with periods of treatment interruption, is now the standard of care in pediatric HIV infection. Although cross-sectional studies have investigated HIV-related differences in cortical morphology in the setting of early ART and ART interruption, the long-term impact on cortical developmental trajectories is unclear. This study compares the longitudinal trajectories of cortical thickness and folding (gyrification) from age 5 to 9 years in a subset of children perinatally infected with HIV (CPHIV) from the Children with HIV Early antiRetroviral therapy (CHER) trial to age-matched children without HIV infection.

METHODS

75 CHER participants in follow-up care at FAMCRU (Family Centre for Research with Ubuntu), as well as 66 age-matched controls, received magnetic resonance imaging (MRI) on a 3 T Siemens Allegra at ages 5, 7 and/or 9 years. MR images were processed, and cortical surfaces reconstructed using the FreeSurfer longitudinal processing stream. Vertex-wise linear mixed effects (LME) analyses were performed across the whole brain to compare the means and linear rates of change of cortical thickness and gyrification from 5 to 9 years between CPHIV and controls, as well as to examine effects of ART interruption.

RESULTS

Children without HIV demonstrated generalized cortical thinning from 5 to 9 years, with the rate of thinning varying by region, as well as regional age-related gyrification increases. Overall, the means and developmental trajectories of cortical thickness and gyrification were similar in CPHIV. However, at an uncorrected p < 0.005, 6 regions were identified where the cortex of CPHIV was thicker than in uninfected children, namely bilateral insula, left supramarginal, lateral orbitofrontal and superior temporal, and right medial superior frontal regions. Planned ART interruption did not affect development of cortical morphometry.

CONCLUSIONS

Although our results suggest that normal development of cortical morphometry between the ages of 5 and 9 years is preserved in CPHIV who started ART early, these findings require further confirmation with longitudinal follow-up through the vulnerable adolescent period.

The experiences of caregivers of children living with HIV and AIDS in Uganda: a qualitative study

Background

Home-based care for HIV patients is popular in contexts severely affected by the epidemic and exacts a heavy toll on caregivers. This study aimed at understanding the experiences of caregivers and their survival strategies.

Methods

A total of 18 caregivers (3 males and 15 females) were interviewed using a semi-structured interview guide, and thematic analysis was used to analyse the data.

Results

Analysis suggests that the caregivers are burdened with insecure provisions for food and difficulties in accessing health care. They however survived these strains through managing their relationships, sharing burden with care-recipients, social networks and instrumental spirituality. These findings are discussed under two major themes: 1). Labour of caregiving and 2). Survivalism.

Conclusions

Home-based care presents huge opportunities for community response to the HIV/AIDS epidemic in African settings. It is however burdensome and thus should not be left for families alone to shoulder. There is therefore an urgent need for protecting home-based care for HIV children in Uganda. Implications for improving and strengthening social interventions in home-based care of HIV/AIDS in the Ugandan context are addressed.
