Evaluation of a practical method to assess antiretroviral adherence in HIV-infected Thai children.

The objective of this study was to evaluate a practical method to assess adherence to antiretroviral therapy by observing virological and immunological responses. We conducted a 12-month longitudinal cohort study of 162 HIV-infected Thai children. Adherence was assessed using 5 methods (self reporting calendar, records of missed doses, pill counts, physician assessment, and an interview questionnaire). CD4 count, percentage and viral load were performed at baseline and at 12 months. Mean adherence rates at 2, 6, and 12 months were 98, 100, and 99% by the calendar method; 98, 100, and 100% by recording missed doses; 96, 96, and 92% by pill count; and 90, 94, and 97% by physician assessment. Poor agreement (kappa < or = 0.1) was found among the methods. There was a statistically significant difference (p = 0.05) in virological response between participants with > or = 95% adherence (0.8 log10) and those with < 95% adherence (0.2 log10) when pill counts were used to assess adherence. In conclusion, despite poor agreement among these tools, a pill count appeared to be the only practical, validated method to differentiate the virological outcome between those who were fully and partially adhere to the treatment regimen.

Diagnosis disclosure in HIV-infected Thai children.

BACKGROUND: Increasing number of children with perinatally acquired HIV-infection are now surviving into school age and adolescence. Disclosure of diagnosis to these children has become an important clinical issue. Clinical reports and studies from other countries suggest that a significant number of these children have not been told of their HIV status. The objective of this study was to assess diagnosis disclosure status of perinatally acquired HIV-infected Thai children. MATERIAL AND METHOD: Primary caregivers of 96 HIV-infected children aged 5 years and older were interviewed to assess the child disclosure status and the caregivers reasons to disclose or not to disclose the diagnosis to the child. The disclosed children were also interviewed to assess perception of their illness. RESULTS: Nineteen of 96 children (19.8%) had been told of their HIV diagnosis by their caregivers. The mean age of the disclosed children was 9.6 years. Eighty-four percent of the disclosed children reported perception of their illness as having HIV infection or AIDS. Common reasons for non-disclosing were concerns that the child was too young, that the child might be psychologically harmed, and that the child could not keep the secret. Of 77 non-disclosing caregivers, 54 reported that they plan to disclose HIV status to the children in the future. CONCLUSION: This study demonstrates that diagnosis disclosure was made in only 1/5 of HIV-infected children, and that most of the caregivers were reluctant in disclosing serostatus to the child. Development of an appropriate guideline for assisting the caregivers and the children to deal with the difficult disclosure process is needed.

Developmental screening by the Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) in HIV- infected children.

Bayley Scales of Infant Development (BSID) is considered to be a standard test for child development. The test requires experienced evaluator and is time consuming; therefore, it is not easy to apply in busy clinic. The Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) is an easy assessment method that has been demonstrated to correlate with BSID in many studies among normal and developmental delayed children, including in HIV-infected infants. We created a pilot system of CAT/CLAMS assessment applied to 16 HIV-infected infants ages 12-34 months. They were all in the normal range score of developmental quotient (DQ). However, longitudinal follow-up by CAT/CLAMS assessment is needed in these HIV-infected children. When DQ score is below 70 (assuming to be delayed development), the child should be evaluated by BSID. In this way delayed development can be screened easily and early developmental stimulation program can be implemented appropriately.
