Reasons for Choice of Antiretroviral Regimens in HIV Patients Presenting Late for Initial Treatment in Europe.
2021
The choice of an optimal antiretroviral therapy (ART) in naive patients presenting late for initial therapy with advanced HIV infection, that is, with a CD4 cell count <200/μL and/or an AIDS-defining disease (late presenters, LPs), is still a challenge, even for HIV specialists. At present, there is little information on the decision process and selection criteria that physicians must take into account when choosing the presumably optimal initial ART for LPs. This study analyzes reasons for the individual choice of first-line ART in HIV LPs. We conducted a prospective multi-center study to analyze the decision-making process of physicians treating naive HIV patients presenting with a CD4 cell count <200/μL and/or an AIDS-defining condition. Two European HIV treatment centers based in Frankfurt (Germany) and A Coruna (Spain) participated in the study. Physicians documented the reasons that led to their decision for a specific first-line ART regimen. A questionnaire was designed for the study. Decisions of the participating physicians were evaluated. A total of 52 treatment decisions were analyzed. Evaluation of the choice of antiretroviral treatment demonstrated that for the overall group of physicians, simplicity of the regimen was the most important selection criterion in 34.6% of cases. The presence of comorbidities was given as the decisive selection criterion in 26.9%, followed by experience with the chosen drugs in 21.2% of cases. In the group of physicians choosing an integrase strand transfer inhibitor (INSTI)-based regimen for first-line ART, the same selection criteria were identified as in the overall group; 33.3% of clinicians selected an INSTI-based regimen because of its simplicity. The presence of comorbidities was the second most frequent decisive criterion (31.0%), followed by personal experience with the prescribed ART (23.8%). In the protease inhibitor group, simplicity was also the most common selection criterion with 40%. Results of clinical trials were stated as the most important criterion for the selection of ART in 38% of all cases, followed by the expected adherence of the patient (22%). Among the physicians who used a non-nucleoside reverse transcriptase inhibitor-based regimen, patients' desire to have children was the most frequent criterion for selection of ART (60%). An ongoing pregnancy was the second most frequent selection criterion, followed by ART's simplicity (8%). For patients treated with a single-tablet regimen, simplicity of ART was comprehensibly the most important decisive criterion (54.5%). Experience with the chosen drugs was the decisive selection criterion in 24.2%, followed by comorbidities in 18.2% of cases. Physicians' selection of individual ART in patients presenting late for first-line treatment seems to be predominantly dependent on patient-centered factors such as adherence issues as well as the clinical experience of physicians with the prescribed drugs.
