Measuring adherence to treatment of paediatric HIV/AIDS

Area of Science:

• Pediatric infectious diseases
• Pharmacology
• Clinical research methodology

Background:

• Adherence to antiretroviral therapy (ART) is critical for managing pediatric Human Immunodeficiency Virus (HIV) infection.
• Accurate measurement of adherence is essential for optimizing treatment outcomes and preventing viral resistance.
• Existing adherence measures in pediatric HIV may have varying degrees of reliability and clinical utility.

Purpose of the Study:

• To evaluate and compare different methods for measuring medication adherence in children with HIV.
• To assess the relationship between various adherence measures and virologic outcomes (viral load).
• To determine the clinical and research utility of parent, child, physician reports, and pill counts in pediatric HIV adherence assessment.

Main Methods:

• Utilized parent, child, and physician self-report questionnaires to assess adherence.
• Employed pill counts as a quantitative measure of adherence.
• Correlated adherence data with viral load measurements in a cohort of pediatric HIV patients.

Main Results:

• Pill counts were deemed invalid and excluded from further analysis.
• No significant correlation was found between the different adherence measures (parent, child, physician report, pill counts).
• Physician-reported adherence was lower than parent-reported adherence, but both parent and physician reports showed a correlation with viral load control.

Conclusions:

• Parent and physician reports appear to be more clinically relevant for assessing adherence in pediatric HIV compared to pill counts.
• The lack of correlation between different adherence measures highlights the complexity of accurately assessing pediatric adherence.
• Further research is needed to refine adherence measurement tools for improved clinical decision-making and research in pediatric HIV management.
