Yuan L, Chen K, Cai Y, Zhou Z, Yang J, Jiqu W, Zhu Q, Zhang H, Niu S, Sun H. Analysis of ART effects and drug resistance in adult HIV/AIDS patients in Meigu County, Liangshan Prefecture, China. BMC Infect Dis 2024; 24:155. [PMID: 38302941 PMCID: PMC10832074 DOI: 10.1186/s12879-024-09048-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 01/23/2024] [Indexed: 02/03/2024] Open
Abstract
BACKGROUND OBJECTIVE This study aimed to understand the basic situation of adults with human immunodeficiency virus (HIV) receiving antiretroviral therapy (ART) in Meigu County, Liangshan Yi Autonomous Prefecture. The information of patients who had been on ART for more than 6 months, the effect of ART, the possible reasons for ART failure, knowledge of drug resistance among patients with ART failure and the possible reasons for the emergence of drug resistance were analyzed. METHODS A total of 2753 people living with HIV (PLWH) were collected for HIV-1 RNA virus nucleic acid testing. Plasma specimens with HIV-1 RNA ≥ 1000 copies/mL were sent to the laboratory for nucleic acid extraction, PCR, electrophoresis and sequencing, and the sequencing results were submitted to the HIV drug resistance database of Stanford University for subtyping to determine the drug resistance mutation sites and drug sensitivity levels. RESULTS A total of 2753 patients were enrolled in this study. Antiviral therapy failed in 288 patients and was successfully amplified in 245, of which 111 had resistance genes. The resistance rate to failure of viral suppression was 45.3% (111/245). The highest rates of resistance to NNRTIs were found for efavirenz (EFV) and nevirapine (NVP) (42.9%), and the highest rates of resistance to NRTIs were found for 3TC and emtricitabine (FTC) (15.9%). The most common NNRTI resistance mutation site was K103N (20.8%), followed by V179D (9.4%) and V106M (7.8%); the most common NRTI resistance mutation site was M184V/I/MV (14.3%), followed by K65R (6.9%); three PI-associated resistance mutation sites were identified. The subtype of the resistant strain was CRF07-BC in almost all patients (98.9%). CONCLUSIONS Compared with the previous low ART efficacy in the county, this study showed that the overall virological failure (VF) resistance rate in the county is still low, dominated by resistance to EFV, NVP, 3TC, FTC, and didanosine (DDI). Due to economic constraints, the core regimen is still 3TC + TDF, but before initiating ART, testing for HIV-1 subtypes and resistance should be conducted to avoid resistance that can lead to VF, especially for patients with high risk factors for resistance as shown by epidemiologic investigations.

Acceptability and feasibility of long-acting injectable antiretroviral therapy for HIV-infected persons who inject drugs in Vietnam: A qualitative study. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 31:100603.

Abstract
BACKGROUND In Vietnam, HIV prevalence among people who inject drugs (PWID) is several times higher than in the general population (15% versus 0.3%). PWID also experience higher rates of HIV-related mortality, driven by poor antiretroviral therapy (ART) adherence. Long-acting injectable ART (LAI) is a compelling opportunity to improve treatment outcomes, but acceptability and feasibility among HIV-infected PWID remains unexplored. METHODS We conducted key informant in-depth interviews in Hanoi, Vietnam (February-November 2021). Participants were purposively sampled and included policymakers, ART clinic staff, and HIV-infected PWID. We applied the Consolidated Framework for Implementation Research to guide study design and analysis, using thematic coding to develop and iteratively refine a codebook and characterize barriers and facilitators to LAI implementation. FINDINGS We interviewed 38 key stakeholders: 19 PWID, 14 ART clinic staff, and five policymakers. Participants were enthusiastic about LAI convenience, highlighting less frequent and more discreet dosing. However, contrasting providers, several policymakers suggested LAI was not needed given perceived exceptional oral ART outcomes and rare viral failure among PWID. Policymakers also criticized strategies prioritizing PWID for LAI, emphasizing equity, whereas providers identified PWID as an ideal population for LAI given adherence challenges. LAI complexity, including storage and administration logistics, were deemed surmountable with training and resources. Finally, providers and policymakers acknowledged that adding LAI to drug formularies was key, but an onerous process. INTERPRETATION Although anticipated to be resource-intensive, LAI was a welcome addition for interviewed stakeholders and likely an acceptable alternative to oral ART among PWID living with HIV in Vietnam. Despite enthusiasm among PWID and providers that LAI could improve viral outcomes, some policymakers-whose buy-in is critical to LAI implementation-opposed strategies that preferentially distributed LAI to PWID, highlighting values of equity and revealing differences in perceived HIV outcomes among PWID. Results provide a vital foundation for developing LAI implementation strategies. FUNDING Supported by National Institutes of Health.

Abstract
Introduction Tuberculosis (TB) is the most common serious opportunistic infection among people with Human Immunodeficiency Virus (HIV) infection and are considered as the double burden diseases of the world. TB is the leading cause of death among people living with HIV, accounting one in three HIV related deaths. Although TB is responsible for high burden of virological unsuppressed in Ethiopia, there is no national level evidence. Therefore, this systematic review and meta-analysis was aimed at estimating the pooled burden of virological unsuppressed among adults with both HIV-TB and impact of TB on virological failure in Ethiopia. Methods The finding of this meta-analysis was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklists. Major data bases PubMed, Scopus, Cochrane Library, Science Direct and Google scholar were searched to access articles. Cochran’s Q statistic quantified with inverse variance was computed to check heterogeneity. Funnel plot visualization and Egger’s test were fitted to assess publication bias across included studies. Random effects model meta-analysis using STATA version-15 statistical software was used to estimate the pooled effect with respective 95% confidence intervals. Results A total of 15 primary studies reporting on impact of tuberculosis on virological unsuppressed among adults living with HIV in Ethiopia were eligible for this meta-analysis. Accordingly, the pooled prevalence of virological unsuppressed among adults with both HIV-TB in Ethiopia was 39.09% (95% CI: 29.04, 49.15). In addition, the odds of virological unsuppressed among adults with both HIV-TB was 2.46 times higher when compared with adults living with HIV infection alone (OR = 2.46, 95% CI: 1.74, 3.46). Conclusion The present systematic review and meta-analysis evidenced that the pooled prevalence of virological unsuppressed among adults with both HIV-TB was much higher than virological unsuppressed among adults living with HIV alone. Moreover, the odds of virological failure among adults with both HIV-TB was significantly higher when compared with among only HIV infection in Ethiopia. Therefore, strengthening TB prevention interventions, early identification and managing the case and prioritizing viral load monitoring and adherence support among adults living with HIV are recommended.

Abstract
Background Antiretroviral therapy (ART) regimen failure is linked to an increased risk of disease progression and death, while early detection of ART failure can help to prevent the development of resistance. This study aimed to evaluate virological and immunological ART failure and predictors among HIV-positive adult and adolescent clients in southeast Ethiopia. Methods A retrospective cohort study was implemented from January 2016 to November 30, 2020; all HIV-positive nave patients on follow-up during the study period from four hospitals were included. Virological and immunological treatment failure was the primary outcome of the study. Cox proportional hazards regression models were employed for analysis. Hazard ratios with 95% confidence intervals were reported and variables with p-values <0.05 were considered statistically significant predictors of treatment failure. Results A total of 641 HIV patients’ charts were reviewed, 62.6% of the study participants were females. Of the total study participants, 18.4% and 15% developed virological and immunological ART regimen treatment failure respectively. The median time to virological failure was 40 months. WHO stage IV [AHR = 4.616; 95% CI: (2.136–9.974)], WHO stage III [AHR = 2.323; 95% CI: (1.317–4.098)], poor adherence to HAART regimen [AHR = 3.097; 95% CI: (1.349–7.108)], and fair adherence [AHR = 2.058; 95% CI: (1.234–3.432)] were significantly associated with virological treatment failure among adolescent and adult study participants in southeast Ethiopia. Conclusion The prevalence of virological treatment failure was 18.4% (95% CI: 15.4 −21.4) and the prevalence of immunological treatment failure was 15% (95% CI: 11.8–18.4). WHO clinical stage III/IV and non-adherence were independent predictors of virological ART treatment failure. Early management of clinical WHO stages and improving patients’ ART regimen adherence are important to decrease the prevalence of ART regimen treatment failure.

Abstract
Background Highly active antiretroviral therapy has dramatically altered progression of HIV infection and significantly improved patients’ quality of life. However, drug resistance with consequent treatment failure raises the need for much more expensive and toxic second-line regimens. Thus, this study aimed at investigating the predictors of virologic failure among adults in Northeast Ethiopia. Methods A retrospective cohort study was carried out among adults who started first-line antiretroviral treatment from September 2005 to January 2018. Data were collected from patients’ medical records, entered and validated using EpiData version 3.1 and then exported to SPSS version 20 for analysis. Binary logistic regression was carried out; odds ratio with 95% CI was used to identify covariates associated with virologic failure. Statistical significance was considered at p-value <0.05. Results A total of 384 patients with mean age of 35.73±9.44 years were consecutively enrolled; of which, 213 (55.5%) were females, 255 (66.4%) had WHO clinical stage III/IV, and 130 (33.9%) had baseline CD4 count <100 cells/mm3. Mean baseline CD4 count was 179 cells/mm3 (range: 2–853 cells), and 158 (41.1%) participants were on AZT/3TC/NVP. Virological failure was diagnosed among 61 (15.9%) patients. The mean time to virologic failure after initiation of ART was 63.80 months (range: 17–150 months). After adjusting for other confounders, risk of experiencing virologic failure was significantly associated with being divorced (AOR 3.40, 95% CI 1.20–9.59), being naïve to ART (AOR 2.55, 95% CI 1.23–5.28), low (<100) baseline CD4 count (AOR 2.39, 95% CI 1.03–5.54) and nonadherence (AOR 6.73, 95% CI 3.29–13.76). Conclusion In this study, the prevalence of antiretroviral treatment failure was 15.9%. Being divorced, being naïve to antiretroviral therapy, low (<100 cells/mm3) baseline CD4 count and nonadherence were found to be significant predictors of virologic failure. ART programs should focus on early HIV diagnosis and ART initiation as well as enhanced adherence support.

Immunological status and virological suppression among HIV-infected adults on highly active antiretroviral therapy. Environ Health Prev Med 2020; 25:43. [PMID: 32838734 PMCID: PMC7444678 DOI: 10.1186/s12199-020-00881-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 08/11/2020] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND World Health Organization (WHO) recommends that viral load ([VL) is a primary tool that clinicians and researchers have used to monitor patients on antiretroviral therapy (ART), an antiviral drug against retroviruses. Whereas, CD4 cell counts can only be used to monitor clinical response to ART in the absence of VL testing service. Therefore, this study is aimed to assess the level of immunological status and virological suppression, and identify associated factors among human immunodeficiency virus ([HIV)-infected adults who were taking antiretroviral drugs of combination regimen know as highly active antiretroviral therapy (HAART). METHODS A hospital-based cross-sectional study was conducted at the University of Gondar comprehensive specialized referral hospital from February to April 2018. A total of 323 adult participants on HAART were selected using a systematic random sampling technique and enrolled into the study. Blood samples for viral load determination and CD4 cell count were collected. Binary logistic regression analysis was used to determine factors associated with immunologic status and virological suppression in HIV patients on HAART. Odds ratio with 95% CI was used to measure the strength of association. RESULTS Virological suppression (VL level < 1000 copies/ml) was found in 82% (95% CI 77.7, 86.1) of study participants, and it has been associated with CD4 cell count between 350 and 499 cells/mm3 (adjusted odds ratio (AOR) = 2.56; 95% CI 1.14, 5.75) and > 499 cells/mm3 (AOR = 7.71; 95% CI 3.48, 17.09) at VL testing and current age > 45 years old (AOR = 5.99; 95% CI 2.12, 16.91). Similarly, favorable immunological status (≥ 400 cells/mm3 for male and ≥ 466 cells/mm3 for female) was observed in 52.9% (95% CI 47.4, 58.8) of the study participants. Baseline CD4 cell count of > 200 cells/mm3, age at enrollment of 26 through 40 years old, and urban residence were significantly associated with favorable immunological status. CONCLUSION Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.

Abstract
BACKGROUND Liangshan Yi Autonomous Prefecture is one of the areas that most severely affected by human immunodeficiency virus (HIV) in China, and virological failure on antiretroviral therapy (ART) is serious in this area. Analyses of prevalence and determinants of ART failure, the genetic diversity and drug resistance among people living with HIV (PLWH) helps improve HIV treatment efficiency and prevent HIV transmission. METHODS A total of 5157 PLWH were recruited from 2016 to 2017. The venous blood samples were subjected to RT-PCR, followed by sequencing of the HIV-1 pol gene, targeting the protease and reverse transcriptase fragments. HIV-1 diversity was analyzed using the DNAStar software and drug resistance mutations were analyzed using the Stanford University HIV Drug Resistance Database. RESULTS A total of 2156 (41.81%) PLWH showed virological failure on ART. Males (ORm = 1.25), heterosexual behaviors and drug injection (ORm = 1.44) and mother to child transmission routes (ORm = 1.58), the clinical stage of AIDS (ORm = 1.35), having used illicit drugs and shared the needles (1-4 times: ORm = 1.34; more than 5 times: ORm = 1.52), having ever replaced ART regimen (ORm = 1.48) increased the risk of virological failure among PLWH, while higher education lever (ORm = 0.77) and ≥ 12 months on ART (12 ~ 36 months: ORm = 0.72; ≥36 months: ORm = 0.66) was associated with lower likelihood of virological failure. The data revealed that CRF07_BC (1508, 95.62%) were the most common strains, and the drug-resistant rate was 32.10% among PLWH with virological failure in this area. The high frequencies of drug resistance were found in EFV and NVP of NNRTIs, ABC, FTC and 3TC of NRTIs, and TPV/r in PIs. The most common mutations in NNRTIs, NRTIs and PIs were K103N/KN (64.69%), M184V/MV/I (36.29%) and Q58E/QE (4.93%), respectively. CONCLUSION We concluded that surveillance of virological failure, HIV-1 subtypes, and drug resistance to understand HIV-1 epidemiology and guide modification of ART guidelines, and target prevention and control strategies should be formatted to reduce the virological failure and drug resistance to promote viral suppression and prevent HIV-1 transmission.

Abstract
BACKGROUND There have been concerns about reduced adherence and human immunodeficiency virus (HIV) virological suppression (VS) among clinically well people initiating antiretroviral therapy (ART) with high pre-ART CD4 cell counts. We compared virological outcomes by pre-ART CD4 count, where universal ART initiation was provided in the HIV Prevention Trials Network 071 (PopART) trial in South Africa prior to routine national and international implementation. METHODS This prospective cohort study included adults initiating ART at facilities providing universal ART since January 2014. VS (<400 copies/mL), confirmed virological failure (VF) (2 consecutive viral loads >1000 copies/mL), and viral rebound were compared between participants in strata of baseline CD4 cell count. RESULTS The sample included 1901 participants. VS was ≥94% among participants with baseline CD4 count ≥500 cells/µL at all 6-month intervals to 30 months. The risk of an elevated viral load (≥400 copies/mL) was independently lower among participants with baseline CD4 count ≥500 cells/µL (3.3%) compared to those with CD4 count 200-499 cells/µL (9.2%) between months 18 and 30 (adjusted relative risk, 0.30 [95% confidence interval, .12-.74]; P = .010). The incidence rate of VF was 7.0, 2.0, and 0.5 per 100 person-years among participants with baseline CD4 count <200, 200-499, and ≥500 cells/µL, respectively (P < .0001). VF was independently lower among participants with baseline CD4 count ≥500 cells/µL (adjusted hazard ratio [aHR], 0.23; P = .045) and 3-fold higher among those with baseline CD4 count <200 cells/µL (aHR, 3.49; P < .0001). CONCLUSIONS Despite previous concerns, participants initiating ART with CD4 counts ≥500 cells/µL had very good virological outcomes, being better than those with CD4 counts 200-499 cells/µL.

Factors Associated With Early Virological Response in HIV-Infected Individuals Starting Antiretroviral Therapy in Brazil (2014-2015): Results From a Large HIV Surveillance Cohort. J Acquir Immune Defic Syndr 2019; 78:e19-e27.

Abstract
Objective: To identify clinical, sociodemographic, and treatment-related factors associated with early virological response in HIV-infected adults starting antiretroviral treatment (ART) in Brazil in 2014–2015. Methods: Data from 4 information systems from the Brazilian AIDS Program were combined to create a historical cohort. Unconditional logistic regression models were used to assess the likelihood of not achieving viral load suppression (VLS), defined as having either a viral load (VL) count >200 copies per milliliter or an aids-related death recorded within 180 ± 90 days after treatment initiation. Results: Among 76,950 individuals, 64.8% were men; median age, CD4+, and VL counts were 34 years, 378 cells per micro liter, and 38,131 copies per milliliter, respectively, and 85.2% achieved VLS. In the multivariate analysis, some factors which increased the odds of non-VLS were as follows: lower CD4+ and higher VL counts, younger age, heterosexual or injection drug use groups (relative to men who have sex with men), lower educational level, black/brown race, higher pill burden, and higher dosing frequency. Regimens containing boosted protease inhibitors were similar to those containing nonnucleoside reverse transcriptase inhibitors and superior to those containing unboosted protease inhibitors (all P values <0.001). No difference was observed between patients with CD4+ counts 350–499 and 500+ cells per micro liter. Conclusions: Our findings support the decision made in Brazil in 2013 to recommend immediate initiation of ART regardless of clinical stage or CD4+. Several factors were found to be associated with poorer virologic outcomes and should be addressed to maximize ART adherence and success rates.

Abstract
Background Medication adherence is frequently suboptimal in adults with chronic diseases, resulting in negative consequences. Motivational interviewing (MI) is a collaborative conversational style for strengthening a person's motivation and commitment to change. We aimed to assess whether MI interventions are effective to enhance medication adherence in adults with chronic diseases and to explore the effect of individual MI intervention characteristics. Methods We searched electronic databases and reference lists of relevant articles to find randomized controlled trials (RCTs) that assessed MI intervention effectiveness on medication adherence in adults with chronic diseases. A random-effects model was used to estimate a pooled MI intervention effect size and its heterogeneity (I 2 ). We also explored the effects of individual MI characteristics on MI intervention effect size using a meta-regression with linear mixed model. Results : Nineteen RCTs were identified, and 16 were included in the meta-analysis. The pooled MI intervention effect size was 0.12 [95% confidence interval (CI) = (0.05, 0.20), I 2 = 1%]. Interventions that were based on MI only [β = 0.183, 95% CI = (0.004, 0.362)] or those in which interventionists were coached during intervention implementation [β = 0.465, 95% CI = (0.028, 0.902)] were the most effective. MI interventions that were delivered solely face to face were more effective than those that were delivered solely by phone [β = 0.270, 95% CI = (0.041, 0.498)]. Conclusions This synthesis of RCTs suggests that MI interventions might be effective at enhancing of medication adherence in adults treated for chronic diseases. Further research is however warranted, as the observed intervention effect size was small.

Abstract
INTRODUCTION Achieving viral suppression is key in the global strategy to end the HIV epidemic. However, the levels of viral suppression have yet to be described in many resource-limited settings. METHODS We investigated the time to virologic failure (VF; defined as a viral load of ≥1000 copies/ml) and changes in CD4 counts since starting antiretroviral therapy (ART) in a cohort of HIV-infected adults in Hanoi, Vietnam. Factors related to the time to VF and impaired early immune recovery (defined as not attaining an increase in 100 cells/mm3 in CD4 counts at 24 months) were further analysed. RESULTS From 1806 participants, 225 were identified as having VF at a median of 50 months of first-line ART. The viral suppression rate at 12 months was 95.5% and survival without VF was maintained above 90% until 42 months. An increase in CD4 counts from the baseline was greater in groups with lower baseline CD4 counts. A younger age (multivariate hazard ratio (HR) 0.75, vs. <30), hepatitis C (HCV)-antibody positivity (HR 1.43), and stavudine (d4T)-containing regimens (HR 1.4, vs. zidovudine (AZT)) were associated with earlier VF. Factors associated with impaired early immune recovery included the male sex (odds ratio (OR) 1.78), HCV-antibody positivity (OR 1.72), d4T-based regimens (OR 0.51, vs. AZT), and nevirapine-based regimens (OR 0.53, vs. efavirenz) after controlling for baseline CD4 counts. CONCLUSION Durable high-rate viral suppression was observed in the cohort of patients on first-line ART in Vietnam. Our results highlight the need to increase adherence support among injection drug users and HCV co-infected patients.

First field evaluation of the optimized CE marked Abbott protocol for HIV RNA testing on dried blood spot in a routine clinical setting in Vietnam. PLoS One 2018; 13:e0191920.

Abstract
Background Viral load (VL) monitoring of HIV-infected patients in decentralized areas is limited due to logistic constraints. Dried Blood Spots (DBS) offer the opportunity to collect samples in remote area which can be easily transferred and tested at a central laboratory. The MOVIDA (Monitoring Of Viral load In Decentralized Area) project evaluated the performance of VL measurements on DBS using the new CE marked optimized Abbott protocol. Methods HIV-1 infected adults from three outpatient clinics in Hanoi (Vietnam) were enrolled into the study between 1 March and 13 April 2017. VL was measured on DBS using the optimized protocol provided by the manufacturer and compared to plasma VL as reference method on the Abbott m2000rt RealTime HIV-1 platform. Sensitivity was defined as the ability for DBS samples to correctly identify VL failure at the threshold of 1000 copies/mL of plasma, while specificity represented the ability to identify patients with a plasma HIV-RNA VL of <1000 copies/mL. Results A total of 203 patients were enrolled in the study, of which 152 (75%) were male. Median age was 38 [inter quartile range: 34–43] years. Of these patients, 37 were untreated, 38 on ART for <6 months and 117 were on ART for ≥6 months. A strong correlation between VL results in plasma and from DBS was observed (ρ = 0.95; p<0.001). Plasma VL was ≥1000 copies/mL in 71 patients. The sensitivity of DBS was 90.1% (95% confidence interval [CI]: 80.7–95.9) and the specificity was 96.2% (95% CI: 91.4–98.8). Conclusions The new optimized Abbott DBS protocol performed well in this study, meeting the WHO performance criteria for the use of DBS for HIV VL monitoring. Scaling up VL monitoring using DBS can be used to reach the last 90 in the UNAIDS targets of 90-90-90 to help end the AIDS epidemics. However, sensitivity remains the main challenge for manufacturers to prevent maintaining patients in virological failure on inefficient ART.

Abstract
Antiretroviral therapy for HIV has led to increased survival of HIV-infected patients. However, tuberculosis remains the leading opportunistic infection and cause of death among people living with HIV/AIDS. Tuberculosis has been shown to be a good predictor of virological failure in this group. This study aimed to evaluate the incidence of tuberculosis and its consequences among individuals diagnosed with virological failure of HIV. This was a retrospective cohort study involving people living with HIV/AIDS being followed-up in an AIDS reference center in Salvador, Bahia, Brazil. Individuals older than 18 years with HIV infection on antiretroviral therapy for at least six months, diagnosed with virological failure (HIV-RNA greater than or equal to 1000 copies/mL), from January to December 2013 were included. Tuberculosis was diagnosed according to the criteria of the Brazilian Society of Pneumology. Fourteen out of 165 (8.5%) patients developed tuberculosis within two years of follow-up (incidence density = 4.1 patient-years). Death was directly related to tuberculosis in 6/14 (42.9%). A high incidence and tuberculosis-related mortality was observed among patients with virological failure. Diagnosis of and prophylaxis for tuberculosis in high-incidence countries such as Brazil is critical to decrease morbidity and mortality in people living with HIV/AIDS.

Abstract
BACKGROUND Interventions based around objective measurement of adherence to antiretroviral drugs for HIV have potential to improve adherence and to enable differentiation of care such that clinical visits are reduced in those with high adherence. It would be useful to understand the approximate upper limit of cost that could be considered for such interventions of a given effectiveness in order to be cost effective. Such information can guide whether to implement an intervention in the light of a trial showing a certain effectiveness and cost. METHODS An individual-based model, calibrated to Zimbabwe, which incorporates effects of adherence and resistance to antiretroviral therapy, was used to model the potential impact of adherence monitoring-based interventions on viral suppression, death rates, disability adjusted life years and costs. Potential component effects of the intervention were: enhanced average adherence when on ART, reduced risk of ART discontinuation, and reduced risk of resistance acquisition. We considered a situation in which viral load monitoring is not available and one in which it is. In the former case, it was assumed that care would be differentiated based on the adherence level, with fewer clinic visits in those demonstrated to have high adherence. In the latter case, care was assumed to be primarily differentiated according to viral load level. The maximum intervention cost required to be cost effective was calculated based on a cost effectiveness threshold of $500 per DALY averted. FINDINGS In the absence of viral load monitoring, an adherence monitoring-based intervention which results in a durable 6% increase in the proportion of ART experienced people with viral load < 1000 cps/mL was cost effective if it cost up to $50 per person-year on ART, mainly driven by the cost savings of differentiation of care. In the presence of viral load monitoring availability, an intervention with a similar effect on viral load suppression was cost-effective when costing $23-$32 per year, depending on whether the adherence intervention is used to reduce the level of need for viral load measurement. CONCLUSION The cost thresholds identified suggest that there is clear scope for adherence monitoring-based interventions to provide net population health gain, with potential cost-effective use in situations where viral load monitoring is or is not available. Our results guide the implementation of future adherence monitoring interventions found in randomized trials to have health benefit.

Abstract
OBJECTIVES Treatment interruptions (TIs) of combination antiretroviral therapy (cART) are known to lead to unfavourable treatment outcomes but do still occur in resource-limited settings. We investigated the effects of TI associated with adverse events (AEs) and non-AE-related reasons, including their durations, on treatment failure after cART resumption in HIV-infected individuals in Asia. METHODS Patients initiating cART between 2006 and 2013 were included. TI was defined as stopping cART for >1 day. Treatment failure was defined as confirmed virological, immunological or clinical failure. Time to treatment failure during cART was analysed using Cox regression, not including periods off treatment. Covariables with P < 0.10 in univariable analyses were included in multivariable analyses, where P < 0.05 was considered statistically significant. RESULTS Of 4549 patients from 13 countries in Asia, 3176 (69.8%) were male and the median age was 34 years. A total of 111 (2.4%) had TIs due to AEs and 135 (3.0%) had TIs for other reasons. Median interruption times were 22 days for AE and 148 days for non-AE TIs. In multivariable analyses, interruptions >30 days were associated with failure (31-180 days HR = 2.66, 95%CI (1.70-4.16); 181-365 days HR = 6.22, 95%CI (3.26-11.86); and >365 days HR = 9.10, 95% CI (4.27-19.38), all P < 0.001, compared to 0-14 days). Reasons for previous TI were not statistically significant (P = 0.158). CONCLUSIONS Duration of interruptions of more than 30 days was the key factor associated with large increases in subsequent risk of treatment failure. If TI is unavoidable, its duration should be minimised to reduce the risk of failure after treatment resumption.
