Outcome of anti-retroviral treatment in HIV-infected orphans and non-orphans at an ART centre in North India

The level of antiretroviral therapy (ART) adherence among orphan children and adolescents living with HIV/AIDS: A systematic review and meta-analysis

BACKGROUND

Many children and adolescents living with HIV have ended up as orphans. Due to HIV taking away their parents leaves them deprived of their most important social network and support, which predisposes them to poor adherence to antiretroviral therapy (ART). Various studies have shown poor adherence to ART among orphaned children and adolescents. This systematic review and meta-analysis, therefore, aims to determine the level of ART adherence among orphaned children and adolescents living with HIV/AIDS.

METHODS

This PROSPERO registered review (CRD42022352867) included studies from PubMed, Google Scholar, Scopus, Web of Science, Africa Journal Online, and selected HIV/AIDS journals from data inception to June 01, 2022. We included articles published in all languages that report the prevalence of adherence to ART among children and adolescent orphans (single parent orphans and/or double orphans) living with HIV/AIDS. We excluded qualitative studies, case studies, opinion papers, and letters to editors. We used the random-effect model to calculate the pooled prevalence of ART adherence based on the highest prevalence provided by the various methods in a particular study. We used the Joanna Briggs Institute Appraisal tool for the prevalence study to evaluate for risk of bias in the included studies. The Egger's test was used to assess small study effects.

RESULTS

Out of 1087 publications identified from the various databases, six met the selection criteria. The included six studies had a total 2013 orphans living with HIV/AIDS. The pooled prevalence of ART adherence was 78∙0% (95% Confidence Interval: 67.4-87.7; I2 = 82.92%, p<0∙001) and ranged between 7∙6% and >95%, using one of the following methods: pill count, caregiver's self-report, clinical attendance, and nevirapine plasma levels (above three μg/mL). The factors associated with adherence were pill burden, caregiver involvement, stunting, and caregiver relationship.

LIMITATION

There was a high level of heterogeneity in the finding.

CONCLUSION

Approximately four fifth of orphan children and adolescents living with HIV/AIDS adhere to ART. Strategies to improve adherence among this group should be prioritized, especially among the double orphaned children and adolescents.

Outcome of highly active antiretroviral therapy in HIV-infected Indian children

BACKGROUND

With the advent of highly active antiretroviral therapy (HAART), HIV infection has become a chronic condition in children with improved survival and quality of life. Reports on long term effectiveness of non-nucleoside reverse transcriptase inhibitor based HAART in HIV-infected children in developing countries are limited.

METHODS

A chart review was conducted and children who received at least six months of HAART between 2004-2011 at All India Institute of Medical Sciences (AIIMS), Delhi were included. The clinical, immunological and virological responses to HAART were documented. Factors predicting non-adherence and non-response to treatment were described.

RESULTS

One seventy five children (boys: 74.9%) were included in the study, with a median follow up of 43 (IQR: 17, 68) months. The median age at diagnosis was 119 (IQR: 75, 156) months. The median CD4 count at start of HAART was 340 cells/μL (IQR: 185,704), which increased to 924 cells/μL (IQR: 591,1278) at 48 months after HAART and plateaued at 749 (IQR: 542,1056) cells/ μL after 90 months of therapy. The weight for age (WAZ) and height for age (HAZ) z score both showed improvement with time after HAART initiation [baseline: WAZ -2.8 (IQR: -4,-1.6), HAZ -2.1 (IQR: -3.4,-0.69); at 42 months of therapy: WAZ -1.2 (IQR: -2.1, 0.01), HAZ -0.75(IQR: -1.6,-0.37)]. Adverse events were reported in 21 (12%) children. Non-adherence to therapy, treatment failure and death were noted in 35 (20%), 9 (5.1%) and 6 (3.4%) children respectively.

CONCLUSIONS

Our experience shows that HAART in HIV-infected children is effective, safe and is associated with good immunological and virological response as well as improvement in growth parameters.
