Frequent change of Antiretroviral Treatment (ART) regimen is a challenging problem especially in a resource-limited setting like Ethiopia where treatment options are limited. This study was aimed to identify reasons for ART regimen change among adult HIV patients at Nedjo General Hospital (NGH).
An institutional-based retrospective cross-sectional study was conducted at NGH by reviewing patient information cards from 2006 to 2016.
From a total of 117 included patients, 50.4% were females and the median (IQR) age of the patients was 28 (24-47) years. Majority of patients, 63 (53.9%) started their treatment at world health organization (WHO) clinical stage III (53.9%) and CD4 count of between 200-350 cells/mm3 (44.54%). At the beginning of ART, 56 (47.9%) patients were on a fixed-dose combination of stavudine-lamivudine-nevirapine (D4T/3TC/NVP). The single-drug substitutions were D4T (n = 63), NVP (n = 34), AZT (n =5), EFV (n = 2), and TDF (n = 1). Majority of the patients, 35(29.9%) switched their initial ART regimen after 3 years of regimen commencement. The common reasons reported for initial regimen change was availability of new drug 46 (39.3%) followed by toxicity/side effects 34 (29.2%). From all toxicities, peripheral neuropathy (47.1%) was the most common toxicity followed by rash (20.6%). After regimen change, 47 (40.2%) were received AZT+3TC+NVP.
Availability of new drug and toxicity were the common reasons for regimen modifications. There should be updated guidelines, sustainable supply of affordable ART drugs, and effective laboratory materials to increase treatment success and minimize the toxicity of the drugs.
