Insights
Drug intolerance, not adherence, most often necessitates changes in antiretroviral therapy for children with AIDS. Increased viral load and poor response also drive treatment adjustments.
Area of Science:
- Pediatric infectious diseases
- Virology
- Clinical pharmacology
Context:
- Vertical transmission of Human Immunodeficiency Virus (HIV) in children presents unique treatment challenges.
- Antiretroviral therapy (ART) regimens require adjustments to optimize outcomes and manage adverse events.
- Understanding factors influencing ART changes is crucial for effective pediatric HIV management.
Purpose:
- To investigate the primary reasons for modifying antiretroviral therapy (ART) in children with Acquired Immunodeficiency Syndrome (AIDS) who acquired HIV through vertical transmission.
- To identify specific clinical and immunological indicators that prompt changes in treatment regimens.
- To determine the relative contribution of various factors, including drug intolerance and adherence, to ART modifications.
Summary:
- A case-control study analyzed 62 children with ART changes and 49 controls between 2000-2005.
- Key drivers for regimen modification included increased viral load (48.4%), poor immunological response (46.6%), and clinical worsening (35.5%).
- Logistic regression identified drug intolerance as the most significant factor influencing medication changes (adjusted OR: 79.94).
Impact:
- Drug intolerance emerged as the predominant factor necessitating ART changes in vertically HIV-infected children.
- Patient adherence was not found to be a significant cause for ART regimen modification.
- Effective management relies on robust service organization and interdisciplinary team collaboration to address treatment challenges.
Abstract:
To identify the causes of changes in therapeutic regimens for treating AIDS in children infected through vertical transmission. This was a case-control study in which the control group consisted of 49 children who had not had any changes to their antiretroviral regimen and the case group consisted of 62 children who had had changes between January 2000 and December 2005. Data from the patients' medical files and a semistructured interview were used. The data analysis was carried out using the SPSS software, and the chi-square test and logistic regression were applied. The main causes of changes in treatment were: increased viral load (48.4%), poor immunological response (46.6%) and clinical worsening (35.5%) of the patients. The adjustment of the data through logistic regression analysis showed that drug intolerance was the variable that contributed most to the change in medication ((adjusted) OR: 79.94; 95% CI: 6.28 -1034.55). Adherence was not shown to be responsible for changes in the anti-retroviral therapy, and this was attributable to the organization of the service and actions of the interdisciplinary team.
