Magnitude and predictors of first-line antiretroviral therapy regimen change among HIV infected adults: A retrospective cross sectional study. Ann Med Surg (Lond) 2022; 81:104303. [PMID: 36147157 PMCID: PMC9486446 DOI: 10.1016/j.amsu.2022.104303] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/25/2022] [Accepted: 07/26/2022] [Indexed: 11/29/2022] Open
Abstract
Background Regimen change remains a significant challenge towards the achievement of human immunodeficiency virus (HIV) treatment success. In developing countries where limited treatment options are available, strategies are required to ensure the sustainability and durability of the starting regimens. Nevertheless, information regarding the rate and predictors of regimen change is limited in these settings. Objective This study was undertaken to determine the prevalence and predictors of changes in ART regimens among patients initiating highly active antiretroviral therapy (HAART) at XX. Materials and methods An institutional based retrospective cross-sectional study was conducted among adult naïve HIV patients who had initiated HAART at XX between 2010. Data were extracted by reviewing their medical charts using a pretested structured check-list. The Kaplan–Meier survival analyses were used to describe the probability of ARV regimen changes while Cox proportional hazard regression models were employed to identify the predictors of ARV regimen modifications. Data were analyzed using SPSS version 21 software, and statistical significant was deemed at p < 0.05. Results A total of 770 patients were enrolled in this study of these 165 (21.43%) had their ART regimen modified at least once. Drug toxicity was the main reason for regimen change followed by TB comorbidity, and treatment failure. Positive baseline TB symptoms (aHR = 1.63, p = 0.037), and Zidovudine based regimen (aHR = 1.76, p = 0.011) as compared to Stavudine based regimen were at higher risk of ART modification. Conversely, urban residence, baseline World Health organization (WHO) stage 2 as compared to WHO stage 1, baseline CD4 count ≥301 as compared to CD4 count ≤200 were at lower risk of ART modification. Conclusion The rate of initial HAART regimen change was found to be high. Thus, less toxic and better tolerated HIV treatment options should be available and used more frequently. Moreover, early detection and initiation of ART by the government is highly demanded to maximize the benefit and reduce risk of ART modifications. The majorities (57.4%) of the patients were female and the mean age of the study participants was 32.9 ± 9.5 A total of 165 (21.4%) participants experienced antiretroviral regimen changes within two years of follow-up period. The highest rate of treatment modification was found among patients receiving fixed-dose combination of AZT+3 TC + NVP 81 (49.0%). Drug toxicity was the main reason for ARV regimen change, which accounts for 74 (41.3%) of regimen change. Anemia was the main forms of toxicities which accounted for 45(36.3%).

Magnitude and causes of first-line antiretroviral therapy regimen changes among HIV patients in Ethiopia: a systematic review and meta-analysis. BMC Pharmacol Toxicol 2019; 20:63.

Abstract
Background Antiretroviral therapy (ART) has markedly decreased the morbidity and mortality due to HIV/AIDS. ART regimen change is a major challenge for the sustainability of human immunodeficiency virus (HIV) treatment program. This is found to be a major concern among HIV/AIDS patients in a resource-limited setting, where treatment options are limited. Objectives The aim of this review is to generate the best available evidence regarding the magnitude of first-line antiretroviral therapy regimen change and the causes for regimen change among HIV patients on ART in Ethiopia. Methods The reviewed studies were accessed through electronic web-based search strategy from PubMed Medline, EMBASE, Hinari, Springer link and Google Scholar. Data were extracted using Microsoft Excel and exported to Stata software version 13 for analyses. The overall pooled estimation of outcomes was calculated using a random-effect model of DerSimonian–Laird method at 95% confidence level. Heterogeneity of studies was determined using I2 statistics. For the magnitude of regimen change, the presence of publication bias was evaluated using the Begg’s and Egger’s tests. The protocol of this systematic review and meta-analysis was registered in the Prospero database with reference number ID: CRD42018099742. The published methodology is available from: https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=99742. Results A total of 22 studies published between the years 2012 and 2018 were included. Out of 22 articles, 14 articles reported the magnitude of regimen change and consisted of 13,668 HIV patients. The estimated national pooled magnitude of regimen change was 37% (95% CI: 34, 44%; Range: 15.1–63.8%) with degree of heterogeneity (I2), 98.7%; p-value < 0.001. Seventeen articles were used to identify the causes for first-line antiretroviral therapy regimen change. The major causes identified were toxicity, 58% (95% CI: 46, 69%; Range: 14.4–88.5%); TB co-morbidity, 12% (95% CI: 8, 16%; Range: 0.8–31.7%); treatment failure, 7% (95% CI: 5, 9%; Range: 0.4–24.4%); and pregnancy, 5% (95% CI: 4, 7%; Range: 0.6–11.9%). Conclusions The original first-line regimen was changed in one-third of HIV patients on ART in Ethiopia. Toxicity of the drugs, TB co-morbidity, treatment failure, and pregnancy were the main causes for the change of the first-line regimen among HIV patients on antiretroviral therapy.

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.
