FACTORS INFLUENCING THE SUBSTITUTION OF ART IN HIV/AIDS PATIENTS ON FIRST LINE HIGHLY ACTIVE ANTIRETROVIRAL THERAPY
Abstract
Â
 Objectives: The aim was to determine the reasons for initial highly active antiretroviral therapy (HAART) regimen changes among human immunodeficiency virus/acquired immunodeficiency syndrome patients on HAART.
Methods: The present study is conducted retrospectively by reviewing the patient treatment records at antiretroviral therapy (ART) center RIMS Teaching Hospital, Raichur. Assessment and analysis were performed inpatient treatment records showing initial regimen changes and to identify the common reasons that resulted in these changes. The data were analyzed using SPSS version 16.0.
Results: A total of 3510 patient records were assessed, 520 cases (14.8%) among these had to change initial HAART regimens. The majority of the patients (53.7%) were males. The most common primary regimen, before the first substitution, was zidovudine/lamivudine/nevirapine (AZT/3TC/NVP) (33%), stavudine/3TC/NVP (25%), tenofovir/3TC/NVP (23%) and AZT/3TC/efavirenz (14%). Main reasons for the substitution to HAART regimens were comorbidity (58.26%), followed by adverse drug reactions (ADR) (38.46%).
Conclusion: Comorbidity was the main reason for the modification of initial HAART among the study population, followed by ADR in ART patients. Reports of comorbidity warrant further investigation, particularly because identifying these conditions are challenging in resource-limited settings.
