Background: Treatment failure (TF) among patients receiving antiretroviral therapy (ART) against human immunodeficiency virus (HIV) impacts on treatment outcome and is becoming a public health concern globally. However, magnitude of TF and factors leading to it are poorly defined in the context of Ethiopia. Thus, the aim of this study was to determine the magnitude of TF and assess its determinants among HIV-infected patients on ART in Ethiopia. Methods: A prospective and retrospective study was conducted from March 2016 to 2017. Retrospective clinical and laboratory data were captured from patients’ medical record. Socio-demographics and explanatory variables of participants were collected using pre-tested structured questionnaire and study participants were followed for additional 6 month after baseline viral load has been done to classify virologic failure (VF). Multiple logistic regression was conducted to assess risk factors associated with TF. Statistical significance was set at P-value less than 0.05. Results: A total of 9,284 adults taking ART from a nationally representative 63 health facilities were included in the study. Viral Load Suppression (VLS) (VL1000 copies/ml at baseline of the study were re-suppressed after six months of enhanced adherence and counseling, leading TF among population on ART in Ethiopia to be 983 (11%). Immunologic and clinical failure was significantly improved from 21.5% and 16.5% at ART initiation to 576 (6.2%) and 470 (5.0%) at baseline of the study, respectively. Medication adherence, disclosure of HIV status, missed appointment to ART, history of ART exposure prior to initiation, residency and marital status had significant association with TF. Conclusions: The high level of VLS (88.1%) could explain the success of ART program in Ethiopia towards achieving the UNAIDS global target on viral suppression. TF among population taking ART in Ethiopia is still a public health concern, since 11% of virally failed population is maintained on failed first-line regimen. However, a significant improvement on immunologic and clinical outcome after ART initiation was maintained. Close follow-up of medication adherence, ensuring disclosure of HIV status, regular appointment follow-up to ART could significantly improve the treatment outcome of population on ART in Ethiopia.

  • Kathryn E Kemper + 9 more

Routine viral load (VL) monitoring is the standard of care in Côte d'Ivoire and allows for effective treatment guidance for people living with human immunodeficiency virus (HIV) to reach viral load suppression (VLS). For VL monitoring to be effective in reducing the impact of HIV, it must be provided in accordance with national guidance. This study aimed to evaluate VL testing, VLS rates and adherence to national guidance for VL testing using data collected from three national laboratories. We collected data on VL testing between 2015-2018 from OpenELIS (OE), an open-source electronic laboratory information system. We merged data by unique patient ID for patients (0-80 years old) who received multiple VL tests to calculate time between tests. We defined VLS as HIV RNA ≤1,000 copies/mL based on Côte d'Ivoire national and WHO guidance at the time of data collection. We used the Kaplan-Meier survival estimator to estimate time between ART (antiretroviral therapy) initiation and the first VL test, time between subsequent VL tests, and to estimate the proportion of people living with HIV (PLHIV) who were virally suppressed within 12 months of ART initiation. At the first documented VL test, 79.6% of patients were virally suppressed (95% CI: 78.9-80.3). Children under 15 were the least likely to be virally suppressed (55.2%, 95% CI: 51.5-58.8). The median time from ART initiation to the first VL sample collection for testing was 7.8 months (IQR:6.2-13.4). 72.4% of patients were virally suppressed within one year of treatment initiation (95% CI:71.5-73.3). Approximately 30% of patients received a second VL test during the 4-year study period. The median time between the first and second VL tests was 24.9 months (IQR: 4.7->40). Most PLHIV received their first VL test within the recommended 12 months of ART initiation but did not receive subsequent VL monitoring tests within the recommended time frame, reducing the benefits of VL monitoring. While VLS was fairly high, children were least likely to be virally suppressed. Our findings highlight the importance of regular VL monitoring after the first VL test, especially for children.

HIV and sickle cell disease (SCD) are significant causes of morbidity and mortality in sub-Saharan Africa. Given their separate roles in immune dysregulation, our objective was to characterise the impact that SCD has on the presentation and progression of paediatric HIV. The study was a retrospective cohort study (study period 2004-2018). Cases of HIV+and SCD-afflicted patients (HIV+/SCD+) were obtained via electronic chart review from a paediatric HIV clinic in Kampala, Uganda and matched 1:3 with HIV+controls without SCD (HIV+/SCD-). Thirty-five HIV+/SCD+subjects and 95 HIV+/SCD- controls were analysed (39% female (51/130), age 3.6years (SD3.9)). At baseline, WHO clinical stage (64% total cohort Stage III/IV) and nutritional status (9.4% severe acute malnutrition) were similar for both groups, whereas HIV+/SCD+had higher though non-significant baseline CD4 count (1036 (SD713) vs 849 (SD638) cells/microlitre, P=0.20, two-tailed t-test). There were 19 deaths, 6 (17%) HIV+/SCD+and 13 (14%) HIV+/SCD-, with unadjusted/adjusted models showing no significant difference. Nutritional progression and clinical stage progression showed no significant differences between groups. Kaplan-Meier analysis showed a slower rate of treatment failures in the HIV+/SCD+cohort (P=0.11, log-rank survival test). Trajectory analysis showed that in the time period analysed, the HIV+/SCD+cohort showed a more rapid rise and higher total CD4 count (P=0.012, regression analysis). The study suggests that SCD does not adversely affect the progression of HIV in patients on ART. Further, HIV+/SCD+achieved higher CD4 counts and fewer HIV treatment failures, suggesting physiological effects due to SCD might mitigate HIV progression.

  • Temesgen Getaneh + 8 more

Objectives:Over the last decades, large number of children living with human immunodeficiency virus (HIV) have been successfully enrolled in care and initiated treatment. However, treatment failure is still a major challenge in the track, missing far too many children. National-level evidence on antiretroviral therapy failure and its associated factors among children receiving highly active antiretroviral therapy is required to alleviate this challenge.Methods:PubMed/Medline, EMBASE, CINAHL, Cochrane library, Google, and Google Scholar databases were used to access eligible studies. This meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In addition, Newcastle–Ottawa Scale quality assessment was applied for critical appraisal. Cochran’s Q statistic, funnel asymmetry plot, and Egger’s test were used to assess heterogeneity and publication bias. Random effect model was computed to explore the pooled burden of treatment failure and its associated factors among children living with HIV. Odds ratio with 95% confidence interval was considered to identify associated factors.Result:The overall pooled prevalence of treatment failure among children living with HIV was 16.6%. Whereas virological, immunological, and clinical failure were 4.49%, 5.41%, and 5.71% respectively, where either of parent is deceased (odds ratio = 2.13, 95% confidence interval: 1.4–3.3), opportunistic infection (odds ratio = 1.67, 95% confidence interval: 1.1–2.5), absence of disclosure of status (odds ratio = 1.6, 95% confidence interval: 1.0–2.5), advanced World Health Organization stage (odds ratio = 4.2, 95% confidence interval: 1.6–10.5), and drug substitution (odds ratio = 2.0, 95% CI: 1.5–2.7) were significantly associated factors.Conclusion:The pooled prevalence of treatment failure among children living with HIV in Ethiopia was lower when compared to most African countries. Accordingly, either prevention or early treatment of opportunistic infection and advanced World Health Organization clinical stages, special care for children whose either parents are deceased, advocating disclosure of status, and avoiding drug substitution as much as possible were still needed to prevent treatment failure.

  • Semei Christopher Mukama + 9 more

BackgroundThis study evaluated the effectiveness and responsiveness of differentiated Human Immunodeficiency Virus (HIV)/Acquired Immuno-Deficiency Syndrome (AIDS) service delivery models (DSDMs) implemented to enhance antiretroviral therapy (ART) access and outcomes for patients while addressing Tuberculosis (TB)-HIV integration, focusing on four of the five DSDMs currently implemented in Uganda.MethodologyA descriptive cross-sectional survey was conducted in eight districts of central Uganda using Lot Quality Assurance Sampling approach from 7th to 23rd March 2023. We randomly sampled 2668 patients who have been on ART for at least 1 year in a Facility-Based Individual Management (FBIM) model or in a non-FBIM DSDM for at least one year. Data were collected through patient interviews and review of records in ART and DSDM registers as well as ART cards. We analyzed the data in proportions, comparing the selected ART outcome and responsiveness indicators between Community Client Led ART Distribution (CCLAD), Community Drugs Distribution Point (CDDP) and Fast-Track Drug Refill (FTDR) DSDMs with the standard care (FBIM) model. The ART outcome variables include patients retained in the 1st line of the ART regimen, patients in World Health Organization clinical stage 1 during the last facility visit, patients who had no CD4 request during the past 12 months, viral load suppression, ART adherence, and patients who reported that they did not experience HIV/AIDS-related symptoms in the past 6 months. The variables on TB care include screening for TB using the intensified case finding form and patients tested positive for TB. Responsiveness variables include the perceived; travel time for ART refill, travel distance for ART refill, convenience and flexibility during ART refill, cost of travel for ART refill, fear of being seen at ART refill point, waiting time before service, adequacy of service time, crowding and risk of infections, social support, ability to address ART treatment challenges, HIV status disclosure and barriers to access. Non-overlap in 95% confidence interval in indicator proportion between non-FBIM DSDM and FBIM means a statistically significant difference in proportion, or otherwise non-significant.ResultsHigher proportions of ART patients in the CCLAD and CDDP DSDMs adhered to ART, had suppressed viral load, and a lower TB prevalence than those in FBIM model. Additionally, more CCLAD and CDDP clients reported shorter travel time and distance to access ART than their counterparts in the FBIM model. Compared to FBIM model, higher proportions of those in CCLAD and CDDP also reported flexibility in ART refill scheduling, reduced transport costs, fewer privacy concerns, less HIV/AIDS-related stigma, shorter waiting times, more efficient services, decreased congestion at ART pickup sites, enhanced peer support, improved problem-solving assistance, and increased HIV status disclosure. The FTDR model outperformed FBIM in proportions with fewer requests for CD4 testing, viral load suppression, as well as proportions of clients who reported; shorter travel time, lower transportation cost, decreased privacy concerns, shorter waiting time, and efficient service provision. Compared to both CDDP and FTDR, the FBIM had a higher proportion of clients remain on the first-line ART regimen.ConclusionCommunity-based DSDMs show responsiveness to clients’ needs without compromising the effectiveness of ART care for patients. Although FTDR also demonstrates high effectiveness and responsiveness for clients on ART, there is potential for further improvement. Planners and implementers of ART programs should consider both demand- and supply-side innovations to sustain the continuation of DSDMs.

BackgroundPeople living with HIV/AIDS (PLWHA) are frequently confronted with severe social issues such as rejection, abandonment, criticism, and stigma. This would negatively affect their quality of life. Several studies have been conducted so far to assess factors affecting the health-related quality of life among people living with HIV/AIDS who are on antiretroviral therapy (ART) in Ethiopia. However, to our knowledge, there is no previous study that has summarized the results of the studies that investigated health-related quality of life (HRQOL) among PLWHA in Ethiopia. Therefore, the purpose of this review was to estimate the pooled prevalence of HRQOL and its association with social support among people living with HIV/AIDS (PLWHA) on ART in Ethiopia.MethodsA systematic search was carried out using several electronic databases (PubMed, Science Direct, Web of Science, and Cochrane electronic), Google Scholar, Google, and a manual search of the literature on health-related quality of life among people living with HIV/AIDS who are on ART. A Microsoft Excel data extraction sheet was used to extract pertinent data from an individual study. To assess the heterogeneity of primary articles, the Cochrane Q test statistics and the I2 test were carried out, and a random effects meta-analysis was used to estimate the pooled prevalence of HRQOL.ResultOut of the 493 articles reviewed, ten with a total of 3257 study participants were eligible for meta-analysis. The pooled prevalence of HRQOL among people living with HIV/AIDS who are on antiretroviral therapy in Ethiopia was 45.27%. We found that strong perceived social support was significantly associated with higher levels of subjectively perceived HRQOL. PLWHA who were on ART and had good social support were four times more likely to report higher HRQOL when compared to their counterparts [AOR = 4.01, 95% CI 3.07–5.23].ConclusionA substantial number of PLWHA had poor HRQOL in Ethiopia. Social support was significantly associated with HRQOL among people living with HIV/AIDS. Hence, it’s recommended to encourage suitable intervention at every follow-up visit, and psycho-social support is also warranted to improve the quality of life.

Viral Load Suppression After Adherence Counselling and Its Predictors Among HIV Patients on Art At Selected Public Health Centers in Addis Ababa
  • Mar 31, 2025
  • American Journal of Nursing and Health Sciences
  • Wakgari Hora + 4 more

<i>Background: </i>For unsuppressed viral load count, World Health Organization (WHO) currently encourages enhanced adherence counseling (EAC) for human immunodeficiency virus (HIV) seropositive people on antiretroviral therapy (ART) before switching the treatment to the second-line regimen. This study aimed to assess viral load suppression after EAC and its predictors among clients on ART. <i>Methods: </i>Institutional-based retrospective cohort study design was used to assess viral load suppression after EAC and its predictors among 175 high viral load and 175 virally suppressed HIV seropositive clients in selected public health centers at Lideta sub-city from November 2019 to December 2022. The magnitude of viral load suppression was determined by proportion. For comparing the probability of viral load suppression Kaplan–Meier curve was used. Cox-regression was used to identify predictors of viral resuppression after EAC. <i>Result:</i> The overall viral load suppression after EAC was 76.2% while viral load suppression among exposed and unexposed group were 72.6% and 80% respectively. The median time to complete the EAC of exposed group was 3 months. In this study, participants who were on ART for more than 12 months had more probability of viral load suppression (13-35 months AHR=6.586, 95% CI: 3.307-13.117, 36-59 months AHR=6.826, 95% CI: 4.316-10.796, ≥60 months AHR=6.596, 95% CI: 4.485-9.700) when compared with ART experience ≤ 12 months. Participants who had not disclosed their serostatus, had history of ART drug discontinuation, were free of opportunistic infection and daily laborer had more viral load suppression, too. <i>Conclusion:</i> This study showed that viral suppression after enhanced adherence counseling was greater than the WHO’s finding (70%) but still below United Nations’ 90-90-90 target. The study findings showed gaps in dalliance of completing recommended time of EAC with repeat viral load testing and needs another assessment with issue of groups’ comparison.

Achieving viral load suppression is crucial for the prevention of complications and deaths related to HIV infection. Ethiopia has embraced the worldwide 95-95-95 target, but there is no national representative information regarding virological suppression. Therefore, this review aims to determine the pooled virological suppression rate and identify the pooled effect of contributing factors of viral suppression for HIV-positive patients on antiretroviral therapy in Ethiopia. We systematically searched websites and databases, including online repositories, to obtain primary studies. Two reviewers assessed the quality of the included articles using the Newcastle-Ottawa Scale appraisal checklist. Publication bias was checked using Egger's regression test, the heterogeneity of the studies was assessed using I2 statistics and Q statistics, and a sensitivity analysis was performed to identify any outlier results in the included studies. The Der Simonian Laird random-effects model was used to estimate the overall proportion of viral suppression, and STATA 17 statistical software was used for all types of analysis. A total of 21 eligible articles primarily conducted in Ethiopia using HIV program data were used for this quantitative synthesis. The overall pooled virological suppression rate was 71% (95% CI, 64%-77%). The pooled effects of poor adherence to ART (adjusted odds ratio [AOR], 0.33; 95% CI, 0.28-0.40), body mass index (18.5-24.9 kg/m2; AOR, 1.8; 95% CI, 1.37-2.36), disclosure (AOR, 1.41; 95% CI, 1.05-1.89), absence of opportunistic infection (AOR, 1.68; 95% CI, 1.43-1.97), and high baseline viral load count (AOR, 0.65; 95% CI, 0.52-0.81) were identified as significant predictors of viral suppression. The overall pooled percentage of virological suppression was low compared with the global target of viral suppression and the Ethiopian Public Health Institute report. Poor adherence, normal body mass index, disclosure, absence of opportunistic infection, and high baseline viral load count were factors contributing to viral suppression in Ethiopia. Responsible stakeholders should maximize their efforts to achieve the global target of virological suppression by addressing significant predictors.

Impact of Pill Burden on Adherence, Risk of Hospitalization, and Viral Suppression in Patients with HIV Infection and AIDS Receiving Antiretroviral Therapy.
  • Apr 1, 2016
  • Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy
  • S Scott Sutton + 2 more

To evaluate the impact of pill burden on outcomes in patients with human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS) receiving antiretroviral therapy (ART) as a single-tablet regimen (STR) or multiple-tablet regimen (MTR). Retrospective cohort study. South Carolina Medicaid medical and pharmacy paid claims data were obtained from the South Carolina Revenue and Fiscal Affairs Office; laboratory data were obtained from the South Carolina Department of Health and Environmental Control. A total of 2174 patients covered by South Carolina Medicaid who were dispensed a complete ART STR (580 patients) or MTR (1594 patients) lasting at least 60 days between January 1, 2006, and December 31, 2013. Outcomes were ART adherence; risk of, time to, and total number of hospitalizations; and viral load suppression. Patients were followed from the index date (start date of their complete ART regimen) until the earliest date of one of the following: treatment discontinuation; treatment switch from MTR to STR, or vice versa; end of study period; last date of Medicaid eligibility; or death. Differences in outcomes were evaluated by using bivariate χ(2) and Wilcoxon rank sum tests, as well as multivariate regression models controlling for covariates measured during a 6-month baseline period. The STR and MTR cohorts were, on average, similar in terms of age at index date, Charlson Comorbidity Index score, sex, drug abuse, and mental health diagnoses, but they differed significantly in racial composition, index year of regimen, previous treatment, baseline viral load, and CD4 measures. The bivariate analysis revealed that the STR cohort was more adherent (p<0.0001), had a lower risk of hospitalization (p=0.0076), and had a higher proportion of patients with viral suppression (64.5% vs 49.5%, p<0.0001). In addition, multivariate regression models revealed that the STR cohort was more adherent and was associated with a lower risk of hospitalization (hazard ratio 0.71, 95% confidence interval 0.59-0.86), but no significant difference in viral load suppression was noted between the STR and MTR cohorts. The STR was associated with higher adherence rates and a lower risk of hospitalization (both in the adjusted and unadjusted analyses) in South Carolina Medicaid patients with HIV infection and AIDS. A higher proportion of patients in the STR cohort had viral suppression during the follow-up period in the unadjusted analysis compared with the MTR cohort; however, no significant difference in viral suppression was observed when controlling for adherence.

BackgroundSustained viral suppression is a critical measure of the effectiveness of antiretroviral therapy (ART) and a vital component in achieving the UNAIDS "95-95-95" strategy, which seeks to ensure that 95% of people with HIV on ART attain viral load suppression by 2030. In the Kyrgyz Republic, where HIV incidence continues to rise, an increasing number of people are on ART. Understanding the factors associated with viral suppression is important for interrupting HIV transmission.Table 1.General characteristics of the study population of people living with HIV on antiretroviral treatment in Kyrgyzstan, 2023.Table 2.Factors associated with viral load suppression among people living with HIV on antiretroviral treatment in Kyrgyzstan, 2023RR: relative risk from bivariable Poisson regression estimators.aRR: adjusted relative risk from multivariable Poisson regression including all variables listed in the tableMethodsWe conducted a retrospective cohort study among adults >18 years old with HIV in Kyrgyzstan. Participants included people initiating or reinitiating ART from June 2021 to June 2023 and who were on ART for at least 6 months. We performed logistic regression to identify factors associated with viral load suppression, defined as >200 copies/ml based on the most recent viral load test.ResultsAmong 377 participants, 95% achieved HIV viral suppression and 85% had undetectable viral load (≤40 copies/ml) (Table 1). Participants were mostly male (60%), 30-49 years old (60%), and self-employed (49%). All were on a dolutegravir containing ART. The proportion of those with viral suppression was below 90% for people who were re-initiating ART, with advanced HIV disease at diagnosis, who started ART more than 3 months after their HIV diagnosis, who injected drugs in last 12 months, and with monthly or unclear frequency of ART appointments. One-quarter of people self-reported an interruption in ART. People without skipped ART doses had higher likelihood of being virally suppressed (adjusted relative risk: 1.11 (95% confidence interval: 1.03-1.19) (Table 2).ConclusionThe results of the study show a high level of viral suppression and Kyrgyzstan is achieving the target of 95% viral load suppression among PLHIV, even though one-quarter of participants reported skipping ART doses. Understanding the frequency and reasons for missed doses is important to maintain high viral suppression.DisclosuresAll Authors: No reported disclosures

  • Emmanuel Bahemana + 20 more

IntroductionWith increased use of antiretroviral therapy (ART), HIV mortality rates are declining and people living with HIV (PLWH) are surviving longer. We characterized CD4 recovery and viral suppression among adults aged < 50 and ≥ 50 years living with HIV who initiated ART in the African Cohort Study (AFRICOS).MethodsBeginning in January 2013, PLWH at twelve clinics in Kenya, Uganda, Tanzania and Nigeria underwent medical history review, CD4 and viral load testing as part of the ongoing African Cohort Study (AFRICOS). ART-naïve PLWH who initiated ART within 30 days of enrollment and had at least one year of follow-up were included in these analyses. To compare ART response in participants < 50 years and ≥ 50 years old, changes in CD4 count and viral load suppression after ART initiation were examined at different time points using linear and binomial regression with generalized estimating equations. Variables for time since ART initiation and the interaction between age group and time on ART were included in the model to evaluate longitudinal changes in CD4 recovery and viral suppression by age.ResultsBetween January 2013 and September 2019, 2918 PLHV were enrolled in the cohort. Of these, 443 were ART naïve and initiated on ART within 30 days of enrollment, with 90% (n = 399) aged < 50 years old at ART initiation. At ART initiation, participants aged 50 and older had a higher median CD4 count compared to participants younger than 50 years of age although it did not reach statistical significance (306 cells/mm3, IQR:130–547 vs. 277cells/mm3, IQR: 132–437). In adjusted models examining CD4 recovery and viral suppression there were no significant differences by age group over time. By the end of follow-up viral suppression was high among both groups of adults (96% of adults ≥ 50 years old and 92% of adults < 50 years old).ConclusionThis study found no difference in long-term CD4 recovery or viral suppression by age at ART initiation. We found that particularly among younger adults participants had lower median CD4 counts at ART initiation, suggesting the importance of identifying and putting this population on treatment earlier in the disease course.

Overview of HIV drug resistance and its implications for China
  • Dec 1, 2006
  • Chinese Medical Journal
  • Fu-Jie Zhang + 3 more

At the end of 2005 an estimated 650 000 people in China were infected with HIV among whom 75 000 were in need of ART. The Division of Treatment and Care at the National Center for AIDS/STD Control and Prevention (NCAIDS) Chinese Center for Disease Control (CCDC) has been responsible for the overall scale up of the National Free ART Program. As of December 2005 a total of 20 453 patients in 28 provinces autonomous regions and special municipalities had benefited from this national program and received free ART. The increase in access to ART however is accompanied by the risk of drug resistance development. A small body of literature already documents HIV drug resistance in China in these treated populations. These preliminary findings are consistent with the development of drug resistance observed in developed countries soon after the initiation of wide-scale HIV treatment. Therefore it is imperative that clinicians understand the causes and implications of HIV resistance in both patientcare and in the public health perspective. (excerpt)
