[PMID: 35110641 PMCID: PMC8810755 DOI: 10.1038/s41598-022-05816-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 01/19/2022] [Indexed: 12/20/2022] Open
Abstract
To report the status of switch rates and time-to-switch of antiretroviral therapy (ART) regimens by evaluating anchor drug classes and common switching patterns in Japanese people living with human immunodeficiency virus (HIV, PLWH). This cross-sectional cohort study extracted data of 28,089 PLWH from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), which contains data representing the entire population of Japan. PLWH with first prescription records of ART administered between January 2011 and March 2019 were identified (n = 16,069). The median time-to-switch and switch rates of anchor drug classes were estimated by Kaplan-Meier analysis. Brookmeyer-Crowley and Greenwood methods were used to estimate 95% confidence intervals for switch rates and median days, respectively. Switch rates were compared between anchor drug classes by year using log-rank tests. A total of 3108 (19.3%) PLWH switched anchor drug classes from first to second regimens. Switch rates increased continuously over 8 years for non-nucleoside reverse transcriptase inhibitors (NNRTIs) (14.9-65.5%) and protease inhibitors (PIs) (13.2-67.7%), with median time-to-switch of 1826 and 1583 days, respectively. Integrase strand transfer inhibitors (INSTIs) maintained a low switch rate (3.0-7.6%), precluding median-days calculation. Overall, the majority of patients treated initially with NNRTIs and PIs switched to INSTIs regardless of switching times (< 1 year: 67.3% and 85.9%, respectively; ≥ 1 year: 95.5% and 93.6%, respectively). The foremost switching strategies for first-to-second ART regimens are from NNRTIs or PIs to INSTIs regimens that maintain low switch rates long term. There was no observable difference in trend between sex, age and status of AIDS disease at first ART regimen. INSTIs HIV agents may be the most durable anchor drug class for PLWH receiving ART.

Chang HM, Chou CH, Tsai HC. Durability of single tablet regimen for patients with HIV infection in Southern Taiwan: data from a real-world setting. BMC Infect Dis 2022; 22:2. [PMID: 34983388 PMCID: PMC8725531 DOI: 10.1186/s12879-021-06919-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 11/29/2021] [Indexed: 12/02/2022] Open
Abstract
Background A single-tablet regimen (STR) has been associated with better drug adherence. However, the durability of different STRs was unknown in the real-world settings. Our aim was to investigate the durability of different initial STR regimens in antiretroviral-naive patients starting STR in southern Taiwan. Method This was a retrospective study of antiretroviral-naive patients that initiated first-line antiretroviral regimens with STRs between May 2016 and December 2017. The primary endpoint was time to virological failure. Secondary endpoints were STR discontinuation due to toxicity/intolerance. Durability was defined as time from the initiation until discontinuation/modification. Kaplan- Meier curves were plotted assessing time to virological suppression, treatment failure and discontinuation for the three STRs and Cox proportional hazards model was used to analyze the factors associated with time to viral suppression, treatment failure or discontinuation. Results Two hundred and twenty-three patients were included: The median follow-up duration (IQR) was 73.9 (48–101.6) weeks, 25 patients (11%) experienced virological failure; the 48 weeks probability of treatment failure was 22.9% (16/70) for Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate (EFV/FTC/TDF), 24.1% (13/54) for Emtricitabine/Rilpivirine/Tenofovir Disoproxil Fumarate (FTC/RPV/TDF) and 24.2% (24/99) for Abacavir/Dolutegravir/Lamivudine (ABC/DTG/3TC) (p=0.16). Fifty-six patients (25%) discontinued their STRs owing to toxicity/intolerance. When compared to EFV/FTC/TDF, treatment with FTC/RPV/TDF (aHR 8.39, CI 1.98–35.58, p = 0.004) and ABC/DTG/3TC (aHR 8.40, CI 2.39–29.54, p=0.001) were more likely to have treatment failure. The predictors for treatment failure included age ≦ 30 years old (aHR 3.73, CI 1.25–11.17, p = 0.018), switch between different STR (aHR 2.3, CI 1.18–4.50, p = 0.001) and free of active syphilis infection (aHR 0.24, CI 0.08–0.73, p = 0.012). The risk factor for treatment discontinuation included younger age ≦ 30 years old (aHR 3.82, CI 1.21–12.37, p = 0.023), treatment with EFV/FTC/TDF (aHR 8.65, CI 2.64–28.39, p < 0.001) and free of active syphilis infection (aHR 0.16, CI 0.04–0.62, p = 0.006). Conclusion Younger age was associated with treatment failure and drug discontinuation. Active syphilis infection s/p treatment was associated with free from treatment failure and discontinuation. This probably driven by the more frequently sexual health education and counseling when patients had syphilis infection. Treatment with ABC/DTG/3TC was associated with higher risk of treatment failure. The STR durability was dependent on the drug toxicity/intolerance, age and syphilis infection.

Late presentation for HIV impairs immunological but not virological response to antiretroviral treatment. AIDS 2021; 35:1283-1293. [PMID: 33813554 DOI: 10.1097/qad.0000000000002891] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVES The aim of this study was to examine the impact of late presentation (CD4+ cell count <350 cells/μl or an AIDS-defining event) on effectiveness and safety of initial antiretroviral therapy (ART) and to evaluate whether treatment response depends on first-line ART regimen in late presenters. DESIGN ART-naive adults from the Cohort of the Spanish HIV/AIDS Research Network (CoRIS) starting triple ART between 2010 and 2018. METHODS We used multivariable models to assess differences in viral suppression (viral load <50 copies/ml), immunological response (change in CD4+ cell count, CD4% (>29%) and CD4/CD8 normalization (>0.4 and >1) multiple T-cell marker recovery (MTMR): CD4+ cell count more than 500 cells/μl and CD4% >29% and CD4/CD8 >1), and treatment discontinuation due to adverse events (TDAE) at 48 weeks from ART initiation. RESULTS Out of 8002 participants, 48.7% were late presenters. Of them, 45.8% initiated ART with a NNRTI- (mostly TDF/FTC/EFV), 33.9% with a protease inhibitor (mostly TDF/FTC+boosted DRV) and 20.3% with an INI-based regimen (mostly ABC/3TC/DTG). At 48 weeks, late presenters had similar viral suppression, but worse immunological response, than non-late presenters with no difference on TDAE. Late presenters initiating with NNRTI-based regimens were more likely to achieve viral suppression than those starting with INI-based, due to the higher chance of achieving viral suppression observed with TDF/FTC/RPV compared to ABC/3TC/DTG. Initial treatment with NNRTI or protease inhibitor based showed similar immunological response than the INI-based regimens, which showed lower rates of TDAE than NNRTI- and protease inhibitor based regimens. CONCLUSION Despite safety and effectiveness of initial ART in terms of viral suppression, late presenters may not experience complete immunological response. In late presenters, effectiveness and safety depends on both the class and the specific first-line ART regimen.
