Abstract
When an initial antiretroviral therapy (ART) regimen is effective and well-tolerated, it can be maintained for years as long as the patient adheres. Prior research has revealed that shorter initial ART duration is associated with regimen type, female sex, injection drug use as the HIV transmission category, and lower baseline CD4 count. We examined potential factors associated with initial regimen discontinuation among a subset of newly diagnosed virally unsuppressed PWH in the DC Cohort, an ongoing prospective observation study that uses electronic health record data from clinic sites to collect relevant information, including demographic and clinical information. Participants were excluded from the analysis if they had less than 6 months of follow-up and were virally suppressed at enrollment. There were 479 individuals included in the study. The median age of participants was 33.9 years [interquartile range (IQR) 26-43.9]. The sample was predominantly male (79.1%) and of Black race (70.8%). Over half of the study participants (56.4%) attended community-based clinic sites. The median time to the discontinuation of initial ART was 2.7 years [95% confidence interval (CI): 2.3, 3.4]. Females had a shorter time to ART discontinuation [adjusted hazard ratio (aHR) 1.55, 95% CI: 1.14, 2.11] as did individuals who started on a protease inhibitor-based regimen versus integrase strand transfer inhibitors (aHR 1.87, 95% CI: 1.34, 2.61) and those receiving HIV care at a community-based site (aHR 1.46, 95% CI: 1.11,1.93). Although limited by lack of reason for discontinuation, we demonstrated that ART-naïve women, community clinic attendees, and patients starting on PIs had a shorter duration of initial ART. More anticipatory guidance may be needed to help patients stay on their initial therapy and manage the side effects or to be flexible in trying different regimens.

Abstract
BACKGROUND Second-line antiretroviral therapy (ART) was introduced in Henan Province in 2009. The number of people living with human immunodeficiency virus (HIV) starting this therapy is increasing. OBJECTIVE This study aimed to investigate the survival and factors affecting mortality among this group. METHODS We conducted a retrospective cohort study of people living with HIV (PLHIV) who switched to second-line ART between May 1, 2010, and May 1, 2016, using the Kaplan-Meier method and Cox proportional hazards models. RESULTS We followed 3,331 PLHIV for 26,988 person-years, of whom 508 (15.3%) died. The mortality rate was 1.88/100 person-years. After adjusting for confounding factors, we found being a woman (hazard ratio (HR), 0.66; 95% confidence interval (CI) 0.55-0.79), > 50 years old (HR, 2.69; 95% CI, 2.03-3.56), single/widowed (HR, 1.26; 95% CI, 1.04-1.52), having > 6 years of education (HR, 0.78; 95% CI, 0.65-0.94), Chinese medicine (HR, 0.75; 95% CI, 0.52-0.96), liver injury (HR, 1.58; 95% CI, 1.19-2.10), and CD4+ T cell count <200 cells/μl (HR, 1.94; 95% CI, 1.47-2.55), or 200-350 cells/μl (HR, 1.37; 95% CI, 1.03-1.82) were associated with mortality risk. CONCLUSIONS We found lower mortality among PLHIV who switched to second-line ART than most previous studies. The limitations of a retrospective cohort may, therefore, have biased the data, and prospective studies are needed to confirm the results. Moreover, Chinese medicine combined with second-line ART shows potential as a treatment for HIV.

Antiretroviral therapy regimen modification rates and associated factors in a cohort of HIV/AIDS patients in Asmara, Eritrea: a 16-year retrospective analysis. Sci Rep 2023; 13:4183. [PMID: 36918596 PMCID: PMC10015006 DOI: 10.1038/s41598-023-30804-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Accepted: 03/01/2023] [Indexed: 03/15/2023] Open
Abstract
Combined antiretroviral therapy (cART) durability and time to modification are important quality indicators in HIV/AIDs treatment programs. This analysis describes the incidence, patterns, and factors associated with cART modifications in HIV patients enrolled in four treatment centers in Asmara, Eritrea from 2005 to 2021. Retrospective cohort study combining data from 5020 [males, 1943 (38.7%) vs. females, 3077 (61.3%)] patients were utilized. Data on multiple demographic and clinical variables were abstracted from patient's charts and cART program registry. Independent predictors of modification and time to specified events were evaluated using a multi-variable Cox-proportional hazards model and Kaplan-Meier analysis. The median (±IQR) age, CD4+ T-cell count, and proportion of patients with WHO Clinical stage III/IV were 48 (IQR 41-55) years; 160 (IQR 80-271) cells/µL; and 2667 (53.25%), respectively. The cumulative frequency of all cause cART modification was 3223 (64%): 2956 (58.8%) substitutions; 37 (0.7%) switches; and both, 230 (4.5%). Following 241,194 person-months (PMFU) of follow-up, incidence rate of cART substitution and switch were 12.3 (95% CI 11.9-12.8) per 1000 PMFU and 3.9 (95% CI 3.2-4.8) per 10,000 PMFU, respectively. Prominent reasons for cART substitution included toxicity/intolerance, drug-shortage, new drug availability, treatment failure, tuberculosis and pregnancy. The most common adverse event (AEs) associated with cART modification included lipodystrophy, anemia and peripheral neuropathy, among others. In the adjusted multivariate Cox regression model, Organisation (Hospital B: aHR = 1.293, 95% CI 1.162-1.439, p value < 0.001) (Hospital D: aHR = 1.799, 95% CI 1.571-2.060, p value < 0.001); Initial WHO clinical stage (Stage III: aHR = 1.116, 95% CI 1.116-1.220, p value < 0.001); NRTI backbone (D4T-based: aHR = 1.849, 95% CI 1.449-2.360, p value < 0.001) were associated with increased cumulative hazard of treatment modification. Baseline weight (aHR = 0.996, 95% CI 0.993-0.999, p value = 0.013); address within Maekel (aHR = 0.854, 95% CI 0.774-0.942, p value = 0.002); AZT-based backbones (aHR = 0.654, 95% CI 0.515-0.830, p value < 0.001); TDF-based backbones: aHR = 0.068, 95% CI 0.051-0.091, p value < 0.001), NVP-based anchors (aHR = 0.889, 95% CI 0.806-0.980, p value = 0.018) were associated with lower cumulative hazards of attrition. The minimal number of switching suggests inadequate VL testing. However, the large number of toxicity/intolerance and drug-shortage driven substitutions highlight important problems in this setting. Consequently, the need to advocate for both sustainable access to safer ARVs in SSA and improvements in local supply chains is warranted.

Abstract
OBJECTIVES In recent decades, the needs of people living with HIV have evolved as life expectancy has greatly improved. Now, a new definition of long-term success (LTS) is necessary to help address the multifaceted needs of all people living with HIV. METHODS We conducted a two-phase research programme to delineate the range of experiences of people living with HIV. The insights garnered from these research phases were explored in a series of expert-led workshops, which led to the development and refinement of the LTS framework. RESULTS The insights generated from the research phases identified a series of themes that form a part of LTS. These themes were subsequently incorporated into the LTS framework, which includes five outcome pillars: sustained undetectable viral load, minimal impact of treatment and clinical monitoring, optimized health-related quality of life, lifelong integration of healthcare, and freedom from stigma and discrimination. A series of supporting statements were also developed by the expert panel to help in the achievement of each of the LTS pillars. CONCLUSIONS The LTS framework offers a comprehensive and person-centric approach that, if achieved, could help improve the long-term well-being of people living with HIV and support the LTS vision of 'every person living with HIV being able to live their best life'.

Abstract
OBJECTIVE The study investigated the durability of switched therapy and factors associated with the viral rebound among patients on second-line antiretroviral therapy (ART) in Uganda. DESIGN A retrospective dynamic cohort of adults initiated on second-line ART after virological failure to first-line ART. METHODS Patients on second-line treatment for at least 6 months between 2007 and 2017 were included. Patients were followed, until they experienced a viral rebound (viral load ≥200 copies/ml). Cumulative probability of viral rebounds and factors associated with viral rebound were determined using Kaplan-Meier methods and Cox proportional hazard models. RESULTS One thousand, one hundred and one participants were enrolled of which 64% were women, the median age was 37 years [interquartile range (IQR) 31-43]. The preswitch median CD4 + cell count and viral load were 128 cells/μl (IQR 58-244) and 45 978 copies/ml (IQR 13 827-139 583), respectively. During the 4190.37 person-years, the incidence rate of viral rebound was 83.29 [95% confidence interval (CI) 74.99-92.49] per 1000 person-years. The probability of viral rebound at 5 and 10 years was 0.29 (95% CI 0.26-0.32) and 0.62 (95% CI 0.55-0.69), respectively. The median rebound-free survival was 8.7 years. Young adults (18-24 years) [adjusted hazard ratio (aHR) 2.49, 95% CI 1.32-4.67], preswitch viral load at least 100 000 copies/ml (aHR 1.53, 95% CI 1.22-1.92), and atazanavir/ritonavir (ATV/r)-based second-line (aHR 1.73, 95% CI 1.29-2.32) were associated with an increased risk of viral rebound. CONCLUSION Switched therapies are durable for 8 years after failure of recommended regimens. A high preswitch viral load, ATV/r-based regimens, and young adulthood are risk factors for viral rebound, which underscores the need for more durable regimens and differentiated care services.

Abstract
INTRODUCTION Medication persistence has rarely been studied for integrase strand transfer inhibitor (INSTI)-based regimens among patients living HIV (PLWH) in Asia. This study investigated medication persistence for newly prescribed INSTI-based regimens in Japan by comparing single-tablet regimens (STRs) versus multiple-tablet regimens (MTRs), based on the Medical Data Vision database. METHODS Adult PLWH with ≥2 claims for antiretroviral therapy (ART) of interest between 1 January 2017 and 30 June 2018 were included if they had a ≥3-month continuous enrolment prior to the index date and a ≥6-month follow-up after the index date. Medication persistence was measured as the duration from initiation to discontinuation of the prescribed INSTI-based regimen. RESULTS Overall, 487 patients were included, with 220 in the STR cohort and 267 in the MTR cohort. Persistence was longer in the STR cohort than in the MTR cohort (mean days on the index regimens: 384.2 vs. 317.3, P < 0.001). MTRs were associated with a higher risk of discontinuation than STRs (hazard ratio [HR], 1.72; 95% confidence interval [CI], 1.18-2.52; P = 0.005). Other factors that were associated with discontinuation were backbone (emtricitabine/tenofovir disoproxil fumarate vs. emtricitabine/tenofovir alafenamide: HR, 5.64; 95% CI, 3.68-8.66; P < 0.001), third agent (raltegravir vs. elvitegravir/cobicistat: HR, 2.06; 95% CI, 1.10-3.86; P = 0.024), age (HR, 1.02; 95% CI, 1.01-1.03; P = 0.007), and the number of non-ART index medications (HR, 1.16; 95% CI, 1.12-1.21; P < 0.001). CONCLUSIONS Among PLWH newly prescribed an INSTI-based regimen in Japan, STRs were associated with longer persistence than MTRs.

Effects of Chinese Medicine on the Survival of AIDS Patients Administered Second-Line ART in Rural Areas of China: A Retrospective Cohort Study Based on Real-World Data. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:5103768. [PMID: 35126600 PMCID: PMC8813253 DOI: 10.1155/2022/5103768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 01/05/2022] [Indexed: 11/18/2022]
Abstract
Objectives Chinese medicine (CM) improves the symptoms of patients with acquired immune deficiency syndrome (AIDS) and prolongs their survival. This real-world study aimed to evaluate the effects of CM on the survival of AIDS patients administered second-line antiretroviral therapy (ART). Methods We conducted a retrospective cohort study of the medical records of patients with AIDS who switched to second-line ART between January 2009 and December 2014. Patients were divided into ART and CM + ART groups. Propensity score matching (PSM) was performed to correct for biases between groups. Kaplan–Meier analysis and the log-rank test were used to compare survival rates, and Cox regression models were employed to identify factors significantly associated with survival. Results The study population (n = 4180) was comprised of the CM + ART group (n = 855) and the ART group (n = 3325). After 1 : 2 PSM, 855 patients in the CM + ART group and 1699 in the ART group were selected for analysis. Patients in the CM + ART group were followed for 4246.8 person-years, and the mortality rate was 2.12/100 person-years. Patients in the ART group were followed for 8381.2 person-years, and the mortality rate was 2.91/100 person-years. Cox regression model analysis revealed that patients in the CM + ART group survived significantly longer than those in the ART group (hazard ratio: 0.73 and 95% confidence interval: 0.57–0.93). Gender, age, symptoms, CD4 cell counts, and viral loads were independently associated with the survival of AIDS patients treated with second-line ART. Conclusions CM significantly improved the survival rate of AIDS patients treated with second-line ART.

Abstract
Background There is limited evidence on the modification or stopping of antiretroviral therapy (ART) regimens, including novel antiretroviral drugs. The aim of this study was to evaluate the discontinuation of first ART before and after the availability of better tolerated and less complex regimens by comparing the frequency, reasons and associations with patient characteristics. Methods A total of 3019 ART-naive patients registered in the HIV-TR cohort who started ART between Jan 2011 and Feb 2017 were studied. Only the first modification within the first year of treatment for each patient was included in the analyses. Reasons were classified as listed in the coded form in the web-based database. Cumulative incidences were analysed using competing risk function and factors associated with discontinuation of the ART regimen were examined using Cox proportional hazards models and Fine-Gray competing risk regression models. Results The initial ART regimen was discontinued in 351 out of 3019 eligible patients (11.6%) within the first year. The main reason for discontinuation was intolerance/toxicity (45.0%), followed by treatment simplification (9.7%), patient willingness (7.4%), poor compliance (7.1%), prevention of future toxicities (6.0%), virologic failure (5.4%), and provider preference (5.4%). Non-nucleoside reverse transcriptase inhibitor (NNRTI)-based (aHR = 4.4, [95% CI 3.0–6.4]; p < 0.0001) or protease inhibitor (PI)-based regimens (aHR = 4.3, [95% CI 3.1–6.0]; p < 0.0001) relative to integrase strand transfer inhibitor (InSTI)-based regimens were significantly associated with ART discontinuation. ART initiated at a later period (2015-Feb 2017) (aHR = 0.6, [95% CI 0.4–0.9]; p < 0.0001) was less likely to be discontinued. A lower rate of treatment discontinuation for intolerance/toxicity was observed with InSTI-based regimens (2.0%) than with NNRTI- (6.6%) and PI-based regimens (7.5%) (p < 0.001). The percentage of patients who achieved HIV RNA < 200 copies/mL within 12 months of ART initiation was 91% in the ART discontinued group vs. 94% in the continued group (p > 0.05). Conclusion ART discontinuation due to intolerance/toxicity and virologic failure decreased over time. InSTI-based regimens were less likely to be discontinued than PI- and NNRTI-based ART.

Abstract
OBJECTIVES To assess second-line antiretroviral therapy (ART) virological failure and HIV drug resistance-associated mutations (RAMs), in support of third-line regimen planning in Asia. METHODS Adults > 18 years of age on second-line ART for ≥ 6 months were eligible. Cross-sectional data on HIV viral load (VL) and genotypic resistance testing were collected or testing was conducted between July 2015 and May 2017 at 12 Asia-Pacific sites. Virological failure (VF) was defined as VL > 1000 copies/mL with a second VL > 1000 copies/mL within 3-6 months. FASTA files were submitted to Stanford University HIV Drug Resistance Database and RAMs were compared against the IAS-USA 2019 mutations list. VF risk factors were analysed using logistic regression. RESULTS Of 1378 patients, 74% were male and 70% acquired HIV through heterosexual exposure. At second-line switch, median [interquartile range (IQR)] age was 37 (32-42) years and median (IQR) CD4 count was 103 (43.5-229.5) cells/µL; 93% received regimens with boosted protease inhibitors (PIs). Median duration on second line was 3 years. Among 101 patients (7%) with VF, CD4 count > 200 cells/µL at switch [odds ratio (OR) = 0.36, 95% confidence interval (CI): 0.17-0.77 vs. CD4 ≤ 50) and HIV exposure through male-male sex (OR = 0.32, 95% CI: 0.17-0.64 vs. heterosexual) or injecting drug use (OR = 0.24, 95% CI: 0.12-0.49) were associated with reduced VF. Of 41 (41%) patients with resistance data, 80% had at least one RAM to nonnucleoside reverse transcriptase inhibitors (NNRTIs), 63% to NRTIs, and 35% to PIs. Of those with PI RAMs, 71% had two or more. CONCLUSIONS There were low proportions with VF and significant RAMs in our cohort, reflecting the durability of current second-line regimens.
