Viral load suppression and its predictor among HIV seropositive people who receive enhanced adherence counseling at public health institutions in Bahir Dar, Northwest Ethiopia. Retrospective follow-up study. PLoS One 2024; 19:e0303243. [PMID: 38739646 PMCID: PMC11090359 DOI: 10.1371/journal.pone.0303243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Accepted: 04/23/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND For those HIV seropositive people with high viral loads, the World Health Organization recommends more counseling before changing ART regimens. A high viral load can lead to increased HIV transmission and lower survival rates. Clients with viral loads above 1000 copies/mL should receive enhanced adherence counseling for 3-6 months before switching. Despite enhanced adherence counseling programs, most countries struggle with viral load suppression. Little is known about viral load suppression in Ethiopia and the research area after counseling. OBJECTIVE This study aims to assess viral load suppression and its predictors among HIV-positive individuals receiving enhanced adherence counseling in Bahir Dar, Northwest Ethiopia, in 2022. METHODS An institution-based retrospective follow-up study was conducted among randomly selected 546 clients on Enhanced Adherence Counseling at public health facilities in Bahir Dar city. The Epicollect5 mobile application was used to collect the data, which was then exported to Stata version 14 for analysis. A Log-Binomial regression model was fitted for each explanatory variable. Variables having a p-value <0.25 in bivariate analysis were entered into a multivariable Log-Binomial regression model. Finally, an adjusted risk ratio with a 95% confidence interval and a p-value <0.05 was used to measure the strength of the prediction. RESULTS Following enhanced adherence counseling, 312 (57.1%) people had their viral load suppressed. Absence of recurrent OI (ARR 1.40; CI 1.03-1.91), EAC stay less than 3 months (ARR 1.54; CI 1.19-1.99), EAC stay 3-6 months (ARR 1.38; CI 1.12-1.69), once-daily ARV dose regimen (ARR 1.28; CI 1.03-1.58), baseline viral load of 2879.00 copies/ml (ARR 1.30, CI 1.06-1.60), being orthodox Tewahido Christian (ARR 0.37; CI 0.18-0.75) were significant predictors of viral load suppression after Enhanced Adherence Counseling. CONCLUSION AND RECOMMENDATION Most importantly, this study found that most people had suppressed viral loads after receiving enhanced adherence counseling. Significant predictors of viral load suppression included recurrent OI, length of stay on EAC, daily ARV dosing regimen, baseline viral load, and religion. Clients with a high baseline viral load and those who experience recurring opportunistic infections should get extra care during EAC sessions.

Viral load suppression after intensive adherence counselling among adult people living with HIV at Kiswa health centre, Kampala: a retrospective cohort study. Secondary data analysis. AIDS Res Ther 2023; 20:18. [PMID: 36998004 PMCID: PMC10061832 DOI: 10.1186/s12981-023-00513-3] [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: 09/12/2022] [Accepted: 03/20/2023] [Indexed: 04/01/2023] Open
Abstract
BACKGROUND The Joint United Nations Programme on HIV/AIDS through the 95-95-95 target requires 95% of people living with HIV (PLHIV) on antiretroviral treatment (ART) to be virally suppressed. Viral Load (VL) non-suppression has been found to be associated with suboptimal ART adherence, and Intensive Adherence Counselling (IAC) has been shown to lead to VL re-suppression by over 70% in PLHIV on ART. Currently, there is data paucity on VL suppression after IAC in adult PLHIV in Uganda. This study aimed to evaluate the proportion of VL suppression after IAC and associated factors among adult PLHIV on ART at Kiswa Health Centre in Kampala, Uganda. METHODS Study was a retrospective cohort design and employed secondary data analysis to review routine program data. Medical records of adult PLHIV on ART for at least six months with VL non-suppression from January 2018 to June 2020 at Kiswa HIV clinic were examined in May 2021. Descriptive statistics were applied to determine sample characteristics and study outcome proportions. Multivariable modified Poisson regression analysis was employed to assess predictors of VL suppression after IAC. RESULTS Analysis included 323 study participants of whom 204 (63.2%) were female, 137 (42.4%) were between the age of 30 and 39 years; and median age was 35 years (interquartile range [IQR] 29-42). Participant linkage to IAC was 100%. Participants who received the first IAC session within 30 days or less after unsuppressed VL result were 48.6% (157/323). Participants who received recommended three or more IAC sessions and achieved VL suppression were 66.4% (202/304). The percentage of participants who completed three IAC sessions in recommended 12 weeks was 34%. Receipt of three IAC sessions (ARR = 1.33, 95%CI: 1.15-1.53, p < 0.001), having baseline VL of 1,000-4,999 copies/ml (ARR = 1.47, 95%CI: 1.25-1.73, p < 0.001) and taking Dolutegravir containing ART regimen were factors significantly associated with VL suppression after IAC. CONCLUSION VL suppression proportion of 66.4% after IAC in this population was comparable to 70%, the percentage over which adherence interventions have been shown to cause VL re-suppression. However, timely IAC intervention is needed from receipt of unsuppressed VL results to IAC process completion.

Abstract
The high cost of viral load (VL) testing limits its use for antiretroviral therapy (ART) adherence support. A low-cost lateral flow urine tenofovir (TFV) rapid assay predicts pre-exposure prophylaxis breakthroughs, but has not yet been investigated in HIV treatment. We therefore evaluated its utility in a pilot cross-sectional study of TFV-containing ART recipients at an increased risk of virologic failure (VF). Participants who had a treatment interruption ≥30 days or had ≥1 episode of viremia (VL ≥400 copies/mL) in the previous year were recruited from a public health setting in Cape Town, South Africa. Self-reported adherence data were collected, the urine TFV assay performed, and concurrent TFV-diphosphate analyzed in dried blood spots. VL testing was done concurrently and, if viremic, genotypic HIV drug resistance testing was performed. Of 48 participants, 18 (37.5%) had VL (>400 copies/mL) at the time of the study, including 16 of 39 receiving efavirenz (EFV), 2 of 6 receiving protease inhibitors, and 0 of 3 receiving dolutegravir. Resistance testing succeeded in 17/18, of which 14 had significant mutations compromising ≥2 agents of the current EFV-based regimen. Of these 14, all had detected urine TFV. Urine TFV was undetectable in two out of three without regimen-relevant resistance; p = .02. In participants on EFV-based regimens returning to care, VF was largely due to viral resistance, where detectable urine TFV had 100% sensitivity (14/14 participants) in predicting resistance. Conversely, when undetectable, the urine-based assay could be used to preclude participants with poor adherence from undergoing costly HIV drug resistance testing.

Abstract
Background Intensive adherence counseling (IAC) is an intervention recommended by the World Health Organization to improve anti-retroviral therapy (ART) adherence among people living with HIV on ART with unsuppressed viral load; and in 2016, the intervention was implemented in Uganda. This study evaluated the effect and experiences of providing IAC in an urban HIV care center in Kampala, Uganda. Methods This was a sequential explanatory mixed-method study that compared viral load suppression during IAC implementation (intervention) to the period before IAC at Kisenyi Health centre IV. Data were abstracted from patient files and viral load register. The effect of IAC on viral load suppression and associated factors were analyzed using modified Poisson regression with robust standard errors. Using in-depth interviews and an inductive analysis approach in Atlas-ti 8. We also explored experiences of providing IAC among healthcare workers. Results A total of 500 records were sampled: 249 (49.8%) in the intervention period and 251 (51.2%) in the pre-intervention period. The mean age was lower during the intervention period 33.1 (± 12.0) than 36.5 (± 13.4) in the pre- intervention period, p = 0.002. More clients were currently on Protease-based regimen in the pre-intervention period 179 (71.3%) than 135 (54.2%) in the intervention period, p ≤ 0.001. In the intervention period, all eligible clients received IAC [249/249 (100.0%)]. Overall, 325 (65.0%) received IAC and of these, 143 (44.1%) achieved viral load suppression compared to 46 (26.3%) who received regular counseling. Receiving IAC significantly increased viral load suppression by 22% (aPR 1.22, 95% CI 1.01–1.47). Clients on Protease-based regimen were less likely to suppress than those on Efavirenz or Nevirapine-based regimens (aPR 0.11, 95% CI 0.08–0.15). All the interviewed healthcare workers lauded IAC for improving ART adherence. However, patient and health care system related factors hindered adherence during IAC. Conclusions The full potential of IAC in achieving viral load suppression in this setting has not been reached due to a combination of the patient and health care system related factors. Provision of adequate IAC necessities and use of patient centered approach should be emphasized to obtain the maximum benefit of the intervention.

Abstract
BACKGROUND Antiretroviral therapy (ART) adherence is a primary determinant of sustained viral suppression, HIV transmission risk, disease progression and death. The World Health Organization recommends that adherence support interventions be provided to people on ART, but implementation is suboptimal. We evaluated linkage to intensive adherence counselling (IAC) for persons on ART with detectable viral load (VL). METHODS Between January and December 2017, we conducted a retrospective chart review of HIV-positive persons on ART with detectable VL (> 1000 copies/ml), in Gomba district, rural Uganda. We abstracted records from eight HIV clinics; seven health center III's (facilities which provide basic preventive and curative care and are headed by clinical officers) and a health center IV (mini-hospital headed by a medical doctor). Linkage to IAC was defined as provision of IAC to ART clients with detectable VL within three months of receipt of results at the health facility. Descriptive statistics and multivariable logistic regression analyses were used to evaluate factors associated with linkage to IAC. RESULTS Of 4,100 HIV-positive persons on ART for at least 6 months, 411 (10%) had detectable VL. The median age was 32 years (interquartile range [IQR] 13-43) and 52% were female. The median duration on ART was 3.2 years (IQR 1.8-4.8). A total of 311 ART clients (81%) were linked to IAC. Receipt of ART at a Health Center level IV was associated with a two-fold higher odds of IAC linkage compared with Health Center level III (adjusted odds ratio [aOR] 1.78; 95% CI 1.00-3.16; p = 0.01). Age, gender, marital status and ART duration were not related to IAC linkage. CONCLUSIONS Linkage to IAC was high among persons with detectable VL in rural Uganda, with greater odds of linkage at a higher-level health facility. Strategies to optimize IAC linkage at lower-level health facilities for persons with suboptimal ART adherence are needed.

Abstract
Background: The World Health Organization recommends that antiretroviral therapy (ART) programs in resource-limited settings develop third-line ART policies. South Africa developed a national third-line ART program for patients who have failed both first-line non-nucleoside reverse transcriptase inhibitor–based ART and second-line protease inhibitor (PI)-based ART. We report on this program. Methods: Third-line ART in South Africa is accessed through a national committee that assesses eligibility and makes individual regimen recommendations. Criteria for third-line include the following: ≥1 year on PI-based ART with virologic failure, despite adherence optimization, and genotypic antiretroviral resistance test showing PI resistance. We describe baseline characteristics and resistance patterns of this cohort and present longitudinal data on virological suppression rates. Results: Between August 2013 and July 2014, 144 patients were approved for third-line ART. Median age was 41 years [interquartile range (IQR): 19–47]; 60% were women (N = 85). Median CD4+ count and viral load were 172 (IQR: 128–351) and 14,759 (IQR: 314–90,378), respectively. About 2.8% started PI-based ART before 2004; 11.1% from 2004 to 2007; 31.3% from 2008 to 2011; and 6.3% from 2012 to 2014 (48.6% unknown start date). Of the 144 patients, 97% and 98% had resistance to lopinavir and atazanavir, respectively; 57% had resistance to darunavir. All were initiated on a regimen containing darunavir, with raltegravir in 101, and etravirine in 33. Among those with at least 1 viral load at least 6 months after third-line approval (n = 118), a large proportion (83%, n = 98) suppressed to <1000 copies per milliliter, and 79% (n = 93) to <400 copies per milliliter. Conclusion: A high proportion of third-line patients with follow-up viral loads are virologically suppressed.

Abstract
INTRODUCTION Guidelines for antiretroviral therapy recommend enhanced adherence counselling be provided to individuals with an initial elevated viral load before making a decision whether to switch antiretroviral regimen. We undertook this systematic review to estimate the proportion of patients with an initial elevated viral load who resuppress following enhanced adherence counselling. METHODS Two databases and two conference abstract sites were searched from January 2012 to October 2019 for studies reporting the number of patients with an elevated viral load whose viral load was undetectable when subsequently assessed. Data were pooled using random effects meta-analysis. RESULTS Fifty-eight studies reported outcomes of 45,720 viraemic patients, mostly from Africa (48 studies), and among patients on first-line antiretroviral therapy (43 studies). Almost half (46.1%, 95% CI 42.6% to 49.5%) of patients with an initial elevated viral load resuppressed following an enhanced adherence intervention. Of those on first-line ART with confirmed virological failure (6280 patients, 21 studies), only 53.4% (40.1% to 66.8%) were appropriately switched to a different regimen. Resuppression was higher among studies that provided details of adherence support. The proportion resuppressing was lower among children (31.2%, 21.1% to 41.3%) and adolescents (40.4%, 15.7% to 65.2%) compared to adults (50.4%, 42.6% to 58.3%). No important differences were observed by date of study publication, gender, viral failure threshold, publication status, time between viral loads or treatment regimen. Information on resistance testing among people with an elevated viral load was inconsistently reported. CONCLUSIONS The findings of this review suggest that in settings with limited resources, current guideline recommendations to provide enhanced adherence counselling can result in resuppression of a substantial number of these patients, avoiding unnecessary drug regimen changes. Appropriate action on viral load results is limited across a range of settings, highlighting the importance of viral load cascade analyses to identify gaps and focus quality improvement to ensure that action is taken on the results of viral load testing.

Lancet HIV 2019; 6:e750-e759.

Abstract
BACKGROUND The decision about whether to switch to third-line antiretroviral therapy (ART) in patients with treatment failure on second-line therapy is difficult in settings with little access to genotypic resistance testing. In this study, we used a standardised algorithm including a wide range of adherence-enhancing interventions followed by a new viral load measurement to decide whether to switch to third-line therapy in this situation. The decision, made on the basis of effectiveness of the adherence reinforcement to drive viral resuppression, did not use genotypic resistance testing. METHODS In this prospective cohort study, adults in four west African countries with treatment failure of a boosted protease inhibitor ART regimen were offered nine adherence reinforcement interventions, and followed up for 64 weeks. We measured viral load at week 12 and used the results to decide ART treatment at week 16: if successful resuppression (plasma HIV-1 RNA <400 copies per mL or had decreased by ≥2 log10 copies per mL compared with baseline), patients continued the same second-line regimen; otherwise they switched to a third-line regimen based on ritonavir-boosted darunavir and raltegravir. The primary endpoint was virological success at week 64 (plasma HIV-1 RNA <50 copies per mL). After study termination we did genotypic resistance testing on frozen plasma samples collected at baseline, and retrospectively determined the appropriateness of the week 16 decision on the basis of the baseline genotypic susceptibility score. FINDINGS Between March 28, 2013, and May 11, 2015, of the 198 eligible participants, five died before week 16. Of the 193 remaining, 130 (67%) reached viral resuppression and continued with second-line ART, and 63 (33%) switched to third-line ART at week 16. Post-study genotypic resistance testing showed that the baseline genotypic susceptibility score was calculable in 166 patients, of whom 57 (34%) had a score less than 2. We retrospectively concluded that the week 16 decision was appropriate in 145 (75%) patients. At week 64, four patients (2%) were lost to follow-up, ten (5%) had died, and 101 (52%) had a viral load less than 50 copies per mL. INTERPRETATION Poor adherence is the first problem to tackle in patients for whom second-line ART is failing when resistance tests are not routinely available and is effectively a manageable problem. Lack of access to genotypic resistance testing should not be an obstacle to the prescription of third-line ART in patients who do not achieve viral resuppression after adherence reinforcement.

Abstract
Background Eligibility for differentiated antiretroviral therapy (ART) delivery models has to date been limited to low-risk stable patients. Objectives We examined the outcomes of patients who accessed their care and treatment through an ART adherence club (AC), a differentiated ART delivery model, immediately following receiving support to achieve viral suppression after experiencing elevated viral loads (VLs) at a high-burden ART clinic in Khayelitsha, South Africa. Methods Beginning in February 2012, patients with VLs above 400 copies/mL either on first- or second-line regimens received a structured intervention developed for patients at risk of treatment failure. Patients who successfully suppressed either on the same regimen or after regimen switch were offered immediate enrolment in an AC facilitated by a lay community health worker. We conducted a retrospective cohort analysis of patients who enrolled in an AC directly after receiving suppression support. We analysed outcomes (retention in care, retention in AC care and viral rebound) using Kaplan–Meier methods with follow-up from October 2012 to June 2015. Results A total of 165 patients were enrolled in an AC following suppression (81.8% female, median age 36.2 years). At the closure of the study, 119 patients (72.0%) were virally suppressed and 148 patients (89.0%) were retained in care. Six, 12 and 18 months after AC enrolment, retention in care was estimated at 98.0%, 95.0% and 89.0%, respectively. Viral suppression was estimated to be maintained by 90.0%, 84.0% and 75.0% of patients at 6, 12 and 18 months after AC enrolment, respectively. Conclusion Our findings suggest that patients who struggled to achieve or maintain viral suppression in routine clinic care can have good retention and viral suppression outcomes in ACs, a differentiated ART delivery model, following suppression support.

Abstract
Poor adherence is a main challenge to successful second-line ART in South Africa. Studies have shown that patients can re-suppress their viral load following intensive adherence counselling. We identify factors associated with failure to re-suppress on second-line ART. The study was a retrospective cohort study which included HIV-positive adults who experienced an elevated viral load ≥400 copies/ml on second-line ART between January 2013-July 2014, had completed an adherence counselling questionnaire and had a repeat viral load result recorded within 6 months of intensive adherence counselling. Log-binomial regression was used to evaluate the association between patient characteristics and social, behavioral or occupational factors and failure to suppress viral load (≥400 copies/ml). A total of 128 patients were included in the analysis, and of these 39% (n = 50) failed to re-suppress their viral load. Compared to those who suppressed, far more patients who failed to suppress reported living with family (44.2% vs. 23.7%), missing a dose in the past week (53.3% vs. 30.0%), using traditional/herbal medications (63.2% vs. 34.3%) or had symptoms suggestive of depression (57.7% vs. 34.3%). These patient-related factors could be targeted for interventions to reduce the risk for treatment failure and prevent switching to expensive third-line ART.

Relationship between untimed plasma lopinavir concentrations and virological outcome on second-line antiretroviral therapy. AIDS 2018; 32:357-361. [PMID: 29309346 DOI: 10.1097/qad.0000000000001688] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
BACKGROUND Resource constraints in low and middle-income countries necessitate practical approaches to optimizing antiretroviral therapy outcomes. We hypothesised that an untimed plasma lopinavir concentration (UPLC) at week 12 would predict loss of virological response in those taking lopinavir as part of a second-line antiretroviral regimen. METHODS We measured plasma lopinavir concentration at week 12 on stored samples from the SECOND-LINE study. We characterized UPLC as: detectable and optimal (≥1000 μg/l); detectable but suboptimal (≥25 to < 1000 μg/l); and undetectable (<25 μg/l). We used Cox regression to explore the relationship between UPLC and loss of virological response over 48 weeks and backwards stepwise logistic regression to explore the relationship between UPLC and other predictors of virological failure at week 48. RESULTS At week 48, we observed virological failure in 15/32 (47%) and 53/485 (11%) of patients with undetectable and detectable UPLC, respectively, P < 0.001. Both suboptimal [adjusted hazard ratio (HR) 2.94; 95% confidence interval (CI) 1.54-5.62; P = 0.001], and undetectable (adjusted HR 3.55; 95% CI 1.89-6.64; P < 0.001) UPLC were associated with higher rates of loss of virological response over 48 weeks. In multivariate analysis, an independent association with virological failure at week 48 and undetectable UPLC was observed after adjustment (odds ratio 5.48; 95% CI 2.23-13.42; P < 0.01). CONCLUSION In low and middle-income countries implementing a public health approach to antiretroviral therapy treatment, an untimed plasma drug concentration may provide a practical method for early identification of patients with inadequate medication adherence and facilitate timely corrective interventions to prevent virological failure.

Changes in second-line regimen durability and continuity of care in relation to national ART guideline changes in South Africa. J Int AIDS Soc 2017; 19:20675.

Abstract
Introduction: Little is known about the impact of antiretroviral therapy (ART) guideline changes on the durability of second-line ART and continuity of care. This study examines predictors of early drug substitutions and treatment interruptions using a cohort analysis of HIV positive adults switched to second-line ART between January 2004 and September 2013 in Johannesburg, South Africa. Methods: The main outcomes were having a drug substitution or treatment interruption in the first 24 months on second-line ART. Kaplan Meiers analyses and Cox proportional hazards regression were used to identify predictors of drug substitutions and treatment interruptions. Results: Of 3028 patients on second-line ART, 353 (11.7%) had a drug substitution (8.6 per 100PY, 95% CI: 7.8–9.6) and 260 (8.6%) had a treatment interruption (6.3 per 100PY, 95% CI: 5.6–7.1). While treatment interruptions decreased from 32.5 per 100PY for the 2004 cohort to 2.3 per 100PY for the 2013 cohort, the rates of drug substitutions steadily increased, peaking at an incidence of 26.7 per 100PY for the 2009 cohort and then decreased to 4.2 per 100PY in the 2011 cohort. Compared to the 2004 to 2008 cohorts, the hazard of early drug substitutions was highest among patients switched to AZT + ddI + LPVr in 2009 to 2010 (aHR 5.1, 95% CI: 3.4–7.1) but remained low over time among patients switched to TDF + 3TC/FTC + LPVr or AZT/ABC + 3TC + LPVr. The main common predictor of both treatment interruption and drug substitution was drug toxicity. Conclusions: Our results show a rapid transition between 2004 and 2010 ART guidelines and concurrent improvements in continuity of care among second-line ART patients. Drug toxicity reporting and monitoring systems need improvements to inform timely regimen changes and ensure that patients remain in care. However, reasons for drug substitutions should be closely monitored to ensure that patients do not run out of treatment options in the future.
