Introduction

HIV-related damage of the central nervous system is manifested in varying severity of neurocognitive disturbances. Research on measures of executive functioning has confirmed that HIV infection is associated with progressive difficulties in these abilities. Moreover, several studies in recent years have shown that an impaired cognitive function confers a higher risk of poor adherence to antiretroviral therapy.

Objectives/Aims

The aim of this study is to analyze the relationship between executive functions and ART compliance.

Methods

We designed a cross-sectional case-control survey. Cases were defined as HIV-infected patients who missing at least 10% intakes in the last year (reported by hospital pharmacy) and self-reported non-adherence by Simplified Medication Adherence Questionnaire (SMAQ). Controls were defined as HIV-infected patients who accomplishing at least last 95% intakes in the last year (reported by hospital pharmacy), and self-reported adherence by SMAQ. Patients with adherences between 90–95% were not included. Executive functions were evaluated with Wisconsin Sorting Card Test. Linear regression was employed as statistical analysis. Results were adjusted for follow-up years. Wisconsin score was already adjusted for gender, age and education level when data were corrected.

Results

Our sample was compound by 63 patients: 37 controls and 26 cases. A statistical signification (P < 0.05) was found for total correct, total errors, perseverative responses, perseverative errors, conceptual level responses and trials to complete first category score between adherence and non-adherence treatment patients.

Conclusions

In our sample worse executive function score, measured by Wisconsin Card Sorting Test, was linked to poor adherence to antiretroviral treatment in HIV patients.
