Time to Treatment Failure and Its Predictors Among Second-Line ART Clients in Amhara Region, Ethiopia: A Retrospective Follow-Up Study.

Second-line antiretroviral treatment failure has become a major public health issue, and the time to treatment failure among second-line ART clients varies globally, and the Sub-Saharan African region having a high rate of second-line ART treatment failures. In addition, after the ART treatment guideline changed there is limited information on Ethiopia. Therefore, this study aimed to assess time to treatment failure and its determinants among second-line ART clients in Amhara Region, Ethiopia. A multi-centered retrospective follow-up study was conducted. A random sample of 860 people on second-line ART was selected by using a computer-generated simple random sampling technique from January 30, 2016, to January 30, 2021, at the University of Gondar Compressive Specialized Hospital, Felege Hiwot Compressive Specialized Referral Hospital, and Debre Tabor Compressive Specialized Referral Hospital, in Amhara region, Ethiopia. Data was captured using a checklist. A total of 81 (9.4%) ART clients developed second-line treatment failure, with a median follow-up time of 29 months with an interquartile range (IQR: 18, 41]. The risk of second-line treatment failure is higher among patients aged 15 to 30 years (adjusted hazard ratio (AHR) = 2.01, 95% confidence interval (CI): [1.16, 3.48]). Being unable to read and write (AHR = 1.312, 95% CI: [1.068, 1.613]), and poor ART drug adherence (AHR = 3.067, 95% CI: [1.845, 5.099]) were significant predictors of second-line ART treatment failures. In the current study, the time to second-line ART treatment failure was high compared with a previous similar study in Ethiopia. Factors like being younger age, ART clients who are not being able to read and write, and having poor ART drug adherence was significant predictors of second-line ART treatment failure.

Second-line anti-retroviral treatment failure and its predictors among patients with HIV in Ethiopia: A systematic review and meta-analysis.

Antiretroviral therapy (ART) treatment failure remains a major public health concern, with multidimensional consequences, including an increased risk of drug resistance, compromised quality of life, and high healthcare costs. However, little is known about the outcomes of second-line ART in Ethiopia. Therefore, this systematic review and meta-analysis aimed to determine the incidence and determinants of second-line ART treatment failure. Articles published in PubMed, Google Scholar, Science Direct, and Scopus databases were systematically searched. All observational studies on the incidence and predictors of treatment failure among patients with HIV on second-line ART were included. A random-effects model was used to estimate the pooled incidence, and subgroup analysis was performed to identify the possible sources of heterogeneity. Publication bias was checked using forest plot, Begg's test, and Egger's test. The pooled odds ratio was also computed for associated factors. Seven studies with 3,962 study participants were included in this study. The pooled incidence of second-line antiretroviral treatment failure was 5.98 (95% CI: 4.32, 7.63) per 100 person-years of observation. Being in the advanced WHO clinical stage at switch (AHR = 2.98, 95% CI: 2.11, 4.25), having a CD4 count <100 cells/mm3 (AHR = 2.14, 95% CI: 1.57, 2.91), poor drug adherence (AHR = 1.78, 95% CI: 1.4, 2.25), and tuberculosis co-infection (AHR = 2.93, 95% CI: 1.93, 4.34) were risk factors for treatment failure. In conclusion, this study revealed that that out of 100 person-years of follow-up, an estimated six patients with HIV who were on second-line antiretroviral therapy experienced treatment failure. The risk of treatment failure was higher in patients who were in an advanced WHO clinical stage, CD4 count <100 cells/mm3, and presence tuberculosis co-infection. Therefore, addressing predictors reduces the risk of treatment failure and maximizes the duration of stay in second-line regimens.

Predictors of antiretroviral treatment failure to the first line therapy: a cross-sectional study among Iranian HIV-positive adults

BackgroundHIV virological failure is one of the main problems in HIV-infected patients, and identifying the main predictors of such treatment failure may help in combating HIV/AIDS.MethodologyThis cross-sectional study included 1800 HIV-infected patients with either virological failure or treatment response. HIV viral load, CD4 count, and other tests were performed. Statistical analysis was used to determine the predictors of virological failure.ResultsClinical stage, treatment with reverse transcriptase inhibitors (RTIs), under therapy for three years or more, suboptimal adherence to antiretroviral treatment (ART), age > 40 years, CD4 count < 200 cells/mm3, unemployment, being infected through sex, and the presence of symptoms were the predominant risk factors for virological failure. In addition, 55% of patients who experienced virological failure failed to experience immunological and/or clinical failure.ConclusionAs the first study in southern Iran and the second in Iran, Iranian policymakers should focus on intensive counseling and adherence support and emphasize more effective treatment regimens such as protease and integrase inhibitors (PIs and INTIs), to increase the chance of a treatment response to ART. The accuracy of identifying clinical and immunological criteria in resource-limited settings is not promising. The present findings can be used to determine effective measures to control HIV treatment failure and design efficient strategies for the ambitious 95–95–95 plan.

Navigating the Antiretroviral Therapy Switch Conundrum: Unveiling the Dilemma of Drug Resistance and Disease Progression in HIV/AIDS.

There is a need to establish consensus for harmonization in antiretroviral (ARV) therapy (ART) switch treatment strategy and address the dilemma that exists in terms of subpar immune response to therapy or an immunologic deterioration while on therapy. The purpose of thisreview is to identifythe factors that contribute to ARV treatment failure, such as insufficient dosage, drug interactions, poor adherence, drug resistance, and poor medication absorption. It is crucial to adopt a more efficient strategy to address this challenging dilemma. After ARV treatment failure, the aim of therapy is virologic suppression, which targets plasma viral load below the limits of detection as assessed by very sensitive tests with lower limits of quantification of 20 to 75 RNA copies/ml. The therapeutic objectives when complete virologic suppression is not possible, should be to maintain or restore immunologic function, stop the progression of the clinical illness, and minimize the emergence of new drug resistance that could further restrict the options for ARV drugs. Treatment history and drug-resistance testing, including the findings of previous and ongoing resistance tests, should be considered while selecting ARV regimens. Hence, the treatment approach post-ARV failure can be personalized based on clinical, immunologic, virologic, or as a mix of the three domains on a case-to-case basis. The evaluation of projected ARV activity should be based on treatment history and previous resistance test findings.

Incidence and predictors of treatment failure among children with HIV on first-line antiretroviral therapy in Wolaita zone, Southern Ethiopia: A multicenter retrospective cohort study

BackgroundAntiretroviral therapy has improved the life expectancy of HIV-positive children. Treatment failure and drug resistance among children with HIV remain major public health concerns despite the rise in ART use. A dearth of evidence exists regarding treatment failure among Ethiopian children from multicenter settings. Therefore, this study sought to assess the incidence and predictors of treatment failure among children with HIV on first-line antiretroviral therapy at health facilities in Wolaita zone, Southern Ethiopia. MethodsA facility-based retrospective cohort study was conducted from January 1, 2017, to December 30, 2021, at health facilities providing ART in Wolaita zone, Southern Ethiopia. A total of 425 children with HIV on first-line ART were selected using a simple random sampling technique. Data were extracted by reviewing the patient's medical record. The data were entered using epi-data version 4.6 and exported to STATA version 15 for analysis. Both bi-variable and multivariable Cox regression analysis were employed. A p-value of less than 0.05 and a hazard ratio with 95 % CI was used to estimate the association between the predictor factors and treatment failure. ResultsThe overall incidence density rate of treatment failure was 3.2 per 1000 person-months of observation (95 % CI: 2.4–4.6). The factors significantly associated with antiretroviral treatment failure were caregiver marital status, single (AHR = 4.86, 95 % CI: 1.52, 15.60), and widowed (AHR = 3.75, 95 % CI: 1.16, 12.11), duration of follow-up (AHR = 4.95, 95 % CI: 1.81, 13.54), and baseline CD4 count (AHR = 4.70, 95 % CI: 1.68, 13.14). ConclusionThe incidence rate of ART failure among children with HIV was found to be significant. Low baseline CD4 count, short follow-up duration on ART, and having a single or widowed caregiver were significantly associated with antiretroviral treatment failure. Early identification of children with low CD4 count and subsequent initiation of ART should be emphasized by stakeholders working in HIV care programs. Healthcare professionals should pay special attention to and regularly monitor the treatment progress of children who have single or widowed caregivers, and those with shorter duration of follow-ups.

Clinical and Immunological Profiles of HIV/AIDS Patients With First-Line Antiretroviral Treatment Failure Attending a Tertiary Care Hospital.

Objectives Highly active antiretroviral therapy (HAART) has decreased morbidity and mortality among HIV/AIDS-infected patients; however, many patients experience treatment failure. The present study aims to evaluate HIV-infected patients' clinical and immunological profiles with first-line antiretroviral treatment (ART) failure (immunological and clinical) at tertiary care hospitals in Northeast India and explore related treatment failure factors. Methods The hospital-based observational study was conducted among HIV-infected patients with first-line ART failure attending a tertiary care hospital from July 1, 2019, to June 30, 2020. The type of first-line ART failure was defined as a clinical, immunological, or virological failure as decided by the State AIDS Clinical Expert Panel (SACEP) meeting. Data were analyzed with Windows MS Excel (Microsoft Corporation, Redmond, Washington) and Statistical Package for the Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Results Among the 90 HIV-infected patients experiencing first-line ART treatment failure, the majority, 38 (42.2%), were in the age group of 30-40 years, 64 (71.1%) were males, and 70 (77.8%) were of average weight. Tuberculosis was the most typical opportunistic infection, affecting 11 (12.2%) patients. Most patients (38.9%) were initially presented at clinical stage 3. Maximum failures were experienced by patients with baseline CD4 ranging from 100-200 cells/mm3, with 38 (42.2%) patients, and by patients on efavirenz (64.5%) and tenofovir-based regimens (56.6%). Failures occurred more for 24-30 months and were common among patients with adherence below 90%. Conclusion Treatment failure was more common among young male patients and those with normal body mass index (BMI). Low baseline CD4 count and poor adherence were influential in the occurrence of treatment failure. First-line ART failure was higher in tenofovir- and efavirenz-based regimens.

Incidence and predictors of antiretroviral treatment failure among children in public health facilities of Kolfe Keranyo Sub-City, Addis Ababa, Ethiopia: Institution-based retrospective cohort study.

Human immunodeficiency virus (HIV) infection is a public health concern globally. The number of people living with HIV worldwide in 2018 was estimated at 37.9 million; of those, 1.7 million are children. Globally, 62% of the 37.9 million people were receiving Antiretroviral treatment (ART); and among those who were on ART, 53% had achieved viral suppression. This study aimed to assess the incidence and predictors of Antiretroviral treatment failure among children in Kolfe Keranyo sub-city, Addis Ababa, Ethiopia. An institution-based retrospective cohort study was conducted among 250 children who were enrolled in first-line Antiretroviral treatment from January 2013 to May 2020 in Kolfe Keranyo sub-city. Data was collected by using a data extraction checklist and data were extracted by reviewing children's medical charts and electronic database. Kaplan-Meier method was used to estimate the probability of treatment failure. During bivariable analysis variables with p-value < 0.25 were taken for multivariable Cox regression analysis to assess predictors of treatment failure. Statistically significant association was declared at p-value < 0.05 with a 95% confidence interval. The overall proportion of treatment failure within the follow-up period was 17.2%. This study also found that the overall incidence rate was 3.45 (95% CI: 2.57-4.67) per 1000 person-month observation. Infant prophylaxis for PMTCT (AHR: 3.59, 95% CI: 1.65-7,82), drug substitution (AHR: 0.18, 95% CI: 0.09-0.37), AZT/3TC/NVP based regimen (AHR: 2.27, 95% CI: 1.14-4.25), and more than 3 episodes of poor ART adherence (AHR: 2.27, 95% CI: 1.17-4.38) were found to be predictors of treatment failure among children. High proportion of treatment failure was found among children on first-line ART in Kolfe Keranyo sub-city, Addis Ababa according to the UNAIDs virological suppression targets. Infant prophylaxis for PMTCT, drug substitution, AZT/3TC/NVP based initial regimen, and poor ART adherence were found to be predictors of first-line ART treatment failure. Close follow-up of children on medication adherence and revising the AZT/3TC/NVP based regimen need to be considered.

Genetic characterization of HIV-1 viruses among cases with antiretroviral therapy failure in Suzhou City, China

BackgroundThis retrospective study aimed to characterize the distribution of HIV-1 genotypes and the prevalence of drug resistance mutations in people with antiretroviral treatment (ART) failure in Suzhou City, China.MethodsPol gene of HIV-1 viruses in blood samples of EDTA anticoagulants from 398 patients with failed antiviral treatment was successfully amplified by using an in-house assay. Drug resistance mutations were analyzed by using the Stanford HIV Drug Resistance Database system (https://hivdb.stanford.edu/hivdb/by-mutations/). HIV-1 genotypes were determined by the REGA HIV subtyping tool (version 3.46, https://www.genomedetective.com/app/typingtool/hiv). Near full-length genomes (NFLG) of HIV-1 viruses were obtained by next generation sequencing method.ResultsSequences analysis of the pol gene revealed that CRF 01_AE (57.29%, 228/398) was the dominant subtype circulating in Suzhou City, followed by CRF 07_BC (17.34%, 69/398), subtype B (7.54%, 30/398), CRF 08_BC (6.53%, 26/398), CRF 67_01B (3.02%, 12/398) and CRF55_01B (2.51%, 10/398). The overall prevalence of drug-resistant mutations in cases with ART failure was 64.57% (257/398), including 45.48% (181/398) for nucleotide reverse transcriptase inhibitors (NRTIs) mutations, 63.32% (252/398) for non-nucleoside reverse transcriptase inhibitors (NNRTIs) mutations, and 3.02% (12/398) for protease inhibitors (PIs) mutations. Ten near full-length genomes (NFLG) of HIV-1 viruses were identified, including six recombinants of CRF 01_AE and subtype B, two recombinants of CRF 01_AE, subtype B and subtype C sequences, one recombinant of CRF 01_AE and subtype C and one recombinant of CRF 01_AE, subtype A1 and subtype C.ConclusionsThe high prevalence of drug-resistant HIV-1 viruses was a serious challenge for HIV prevention and treatment of people with HIV infection. Treatment regimens for ART failure patients should be adjusted over time based on the outcome of drug resistance tests. NFLG sequencing facilitates the identification of new recombinants of HIV-1.

Antiretroviral treatment failure and associated factors among people living with HIV on therapy in Homa Bay, Kenya: A retrospective study.

Despite large numbers of patients accessing antiretroviral treatment (ART) in Kenya, few studies have explored factors associated with virologic failure in Western Kenya, specifically. We undertook a study in Homa Bay County, Kenya to assess the extent of virologic treatment failure and factors associated with it. This was an observational retrospective study conducted from September 2020 to January 2021. Data were abstracted from the records of patients who had been on ART for at least six months at the time of data collection after systematic sampling stratified by age group at ART initiation (0-14 and 15+ years), using probability proportion to the numbers of patients attending the facility. Confirmed viral treatment failure was defined as viral load ≥1000 copies/ml based on two consecutive viral load measurements after at least three months of enhanced adherence counseling. Data were analyzed using descriptive statistics and Cox regression modeling. Of the 2,007 patients sampled, 160 (8.0%) had confirmed virologic treatment failure. Significantly higher virologic treatment failure rates were identified among male patients 78/830 (9.4%) and children 115/782 (14.7%). Factors associated with virologic treatment failure (VTF), were age 0-14 years, adjusted hazard ratio (AHR) 4.42, (95% Confidence Interval [CI], 3.12, 6.32), experience of treatment side effects AHD: 2.43, (95% CI, 1.76, 3.37), attending level 2/3 health facility, AHR: 1.87, (95% CI: 1.29, 2,72), and history of opportunistic infections (OIs), AHR: 1.81, (95% CI, 1.76, 3.37). Children, attendees of level 2/3 health facilities, patients with a history of OIs, and those experiencing treatment side-effects are at risk of VTF. Increased focus on children and adolescents on screening for drug resistance, administration of and adherence to medication, and on effective information and education on side-effects is critical. Additionally, there is need for increased training and support for health care workers at primary level care facilities.

Prevalence and predictors of virological failure in pediatric patients on HAART in sub-Saharan Africa: a systematic review and meta-analysis.

Antiretroviral treatment failure has emerged as a challenge in the management of pediatric human immunodeficiency virus (HIV) patients, especially in resource-limited countries despite accessibility to Highly Active Antiretroviral Therapy (HAART). A systematic review and meta-analysis was conducted to synthesize virological failure (VF) prevalence and ascertain its predictors in children in sub-Saharan Africa. An electronic database search strategy was conducted from January to September 2021 on PubMed, EMBASE, SCOPUS, HINARI, and CINAHL. Further, manual searching was conducted on non-indexed journals. Utilizing the JASP© version 0.17.2 (2023) statistical software, a meta-analysis of pooled prevalence of VF was estimated using the standardized mean differences. Further, selection models were used to assess the risk of bias and heterogeneity. The pooled odds ratios were estimated for the respective studies reporting on predictors of VF. The overall pooled estimate of the prevalence of VF in sub-Saharan Africa among the sampled population was 29% (95% CI: 27.0-32.0; p<0.001). Predictors of VF were drug resistance (OR: 1.68; 95% CI: 0.88-2.49; p < 0.001), poor adherence (OR: 5.35; 95% CI: 5.26-5.45; p < 0.001), nevirapine (NVP)-based regimen (OR: 5.11; 95% CI: 4.66-5.56; p < 0.001), non-usage of cotrimoxazole prophylaxis (OR: 4.30; 95% CI: 4.13-4.47; p < 0.001), higher viral load at the initiation of antiretroviral therapy (ART) (OR: 244.32; 95% CI: 244.2-244.47; p <0.001), exposure to the prevention of mother to child transmission (PMTCT) (OR: 8.02; 95%CI: 7.58-8.46; p < 0.001), increased age/older age (OR: 3.37; 95% CI: 2.70-4.04; p < 0.001), advanced World Health Organization (WHO) stage (OR: 6.57; 95% CI: 6.17-6.98; p < 0.001), not having both parents as primary caregivers (OR: 3.01; 95% CI: 2.50-3.53; p < 0.001), and tuberclosis (TB) treatment (OR: 4.22; 95% CI: 3.68-4.76; p <0.001). The mean VF prevalence documented is at variance with studies in other developing countries outside the sub-Saharan region. The high prevalence of HIV cases contrasting with the limited expertise in the management of pediatric ART patients could explain this variance.

Increased Viral Suppression Among People on First-Line Antiretroviral Treatment in Ethiopia: Meeting the Third 90’s

Background Antiretroviral therapy (ART), which aims to completely suppress viral replication, fails for a variety of reasons. The aim of this study was to identify factors associated with prevalence and treatment failure in ART patients who received first-line treatment in the Amhara region of northeastern Ethiopia. Methods A cross-sectional study was conducted from March 2018 to July 2018. Survey using a pre-structured questionnaire focused on demographics and potential risk factors for antiretroviral treatment failure was used. Medical history, including baseline features, was extracted by reviewing medical records and data was analyzed using STATA version 14. Results A total of 640 clients of all age from 16 health facilities were enrolled in the study. The overall treatment failure of first line antiretroviral drugs was 19.04% with clinical, immunologic and viral failure of 0.31%, 12.66% and 6.09% respectively. More than half of the 57 participants with an unsuppressed viral load (&gt;1000 copies/ml at 6 months), 29 (50.88%) were dropped out from follow up. Females had a higher proportion of immunologic failure (13.09%), but males had a higher proportion of viral failure (8.09%). A high proportion of overall treatment failure (33.33%), immunologic failure (18.75%), as well as viral failure (14.58%), was observed in age groups under the age of 18 years. Multivariate logistic regression revealed clients with a CD4 baseline count of less than 250 and fair/poor adherence had higher odds of treatment failure. Conclusions In this study we conclude that antiretroviral treatment failure indicated by viral failure in Amhara region, Ethiopia is 6.09% which indicated increased viral suppression as compared to Ethiopia’s national viral failure rate of 11%. Low CD4 baseline count and fair/poor adherence are significantly associated independent predictors of treatment failure. Therefore improving client follow up to adherence to treatment should be strengthened and ART program should focus on strengthening test and start strategy to enroll clients early before CD4 count declines. A higher proportion of viral failure in male and younger age suggests acquisition of resistant viral strain and indicate the need for a drug resistance survey

1257. Antiretroviral treatment failure in a prospective cohort of Persons Living with HIV in the Philippines

Abstract Background Widespread access to antiretrovirals has resulted in improved survival among PLHIV in resource-limited settings. In a previous study, ART failure in the Philippines after one year was found to be 10.3%. However, this was done as a cross-sectional study and did not capture dropouts or pre-existing drug resistance (PDR). Treatment failure, taking into account PDR, dropouts, and long-term viral suppression has not been studied. As part of a transmitted drug resistance (TDR) study, we prospectively followed patients and documented long-term viral suppression. Methods We enrolled 227 treatment-naïve PLHIV without TDR on Sanger-based sequencing and measured viral load (VL) every 6 months. VL “&amp;gt;”1000 copies/mL after initiation of treatment was considered treatment failure. An intention to treat analysis counting loss to follow-up as treatment failure was performed along with secondary analysis by subtype. Results Treatment failure at different time points are shown in Table 1. Of the 227 patients, 177 were subtype CRF01_AE, 30 were B, 14 were CRF01_AE/B recombinants, 2 were subtype CRF02_AG, 2 were CRF01_AE/B/F recombinants and one was an A1/D recombinant. Median VL was 295,000 copies/mL at baseline (range: 40 - 658,000 copies/mL). Seventeen PLHIV developed treatment failure over an observation time of up to 60 months, while 74 were lost to follow-up. Comparison between B and non-B subtypes showed a higher rate of failure among non-B subtypes (OR 2.868 95% CI 1.018 to 10.016 p=0.0380) at one year, but this was no longer significant at 24 months (p=0.1534) and 48 months (p=0.0716). Conclusion HIV viral suppression at one year of treatment is 65.6% in an intention to treat analysis. It is 63.4% at 24 months and 60.8% at 48 months. Excluding dropouts, viral suppression is 95.5%, 92.3%, and 89.0% at 12, 24, and 48 months, respectively. Non-B subtypes are more likely to fail than those with B subtypes in the first year of treatment. Loss to follow-up is a significant problem in the Philippines and needs to be addressed proactively in order to improve local efforts to reach the 90-90-90 thresholds of UNAIDS for control of HIV in the country.

Lessons Learned from the Impact of HIV Status Disclosure to Children after First-Line Antiretroviral Treatment Failure in Kinshasa, DR Congo.

HIV status disclosure to children remains a challenge in sub-Saharan Africa. For sociocultural reasons, parents often delay disclosure with subsequent risks to treatment compliance and the child's psychological well-being. This article assesses the effects of HIV disclosure on second-line ART compliance after first-line failure. We conducted a retrospective study of 52 HIV-positive children at Kalembelembe Pediatric Hospital in Kinshasa who were unaware of their HIV status and had failed to respond to the first-line ART. Before starting second-line ART, some parents agreed to disclosure. All children were followed before and during the second-line ART. Conventional usual descriptive statistics were used. For analysis, the children were divided into two groups: disclosed to (n = 39) and not disclosed to (n = 13). Before starting the second-line ART, there was no difference in CD4 count between the two groups (p = 0.28). At the end of the first year of second-line ART, the difference was statistically significant between the two groups with regard to CD4% (p &lt; 0.001) and deaths (p = 0.001). The children disclosed to also reported fewer depressive symptoms post-disclosure and had three times fewer clinic visits. HIV status disclosure to children is an important determinant of ART compliance and a child's psychological well-being.

First line antiretroviral treatment failure and its association with drug substitution and sex among children in Ethiopia: systematic review and meta-analysis

Antiretroviral Treatment (ART) has significantly decreased HIV-related morbidity and mortality among children despite the issue of drug resistance and subsequent treatment failure appearing as a challenge. Different studies have been conducted in Ethiopia regarding the prevalence of first-line ART failure among children but the magnitudes of these studies were inconsistent and had great variability. This review aimed to estimate the pooled prevalence of first line ART failure among children and its association with drug substitution and sex of children among first-line ART users in Ethiopia. The review was conducted using both published and unpublished studies until September 2020 in Ethiopia. MEDLINE, PubMed, Hinari, Web of Science, Google Scholar, Africa journal online (AJOL), Open gray literature, and online repository articles were searched. The quality of individual studies was assessed by Joanna Briggs Institute's (JBI) critical appraisal checklist. The statistical analysis was done by STATA-14 software and a random effect model was used. Heterogeneity was assessed using forest plot Cochrane Q–test and I-squared statistic. Publication bias was checked by using a funnel plot and Egger’s and Begg’s statistical tests. The interpretation was made by an odds ratio and with their respective 95% confidence intervals. The heterogeneity rate was 90% and Begg’s and Egger’s for publication bias were insignificant with p-values of 0.89 and 0.11 respectively. The pooled prevalence of pediatric first line ART failure in Ethiopia was 14.98% (95% CI 11.74, 18.21). Subgroup analysis showed that the highest failure rate was virological (9.13%). Female children had 1.4 times more risk of first-line ART failure (OR = 1.42; 95% CI 1.08, 1.85). First-line ART failure among children in Ethiopia is considerably high. Being female increases the likelihood of facing first line ART failure. More attention should be given to female children.

Factors Associated with Virological Failure among Human Immunodeficiency Virus Infected Patients in Haho Health District Hospital, Togo, 2019

The aim of antiretroviral treatment (ART) is to achieve viral load suppression in every Human Immunodeficiency Virus (HIV) infected person. In low- and middle-income countries like Togo, the disparity in accessibility to ART facilities happens to be one of the most causes of lack in follow-up of infected patients, exposing them to ART failure. This study aims at describing the epidemiological profile of ART outcome and its associated factors in a context of low accessibility to viral load testing facilities in Haho health district in Togo. A cross sectional descriptive and analytical study using a questionnaire filled by reviewing patient's files, was conducted from January to December 2019. The study included all the HIV-positive patients that came for their routine check-up and have been assessed for viral load and have their laboratory results out during this period. The results showed a prevalence of 28.5% of virological failure among patients under ART in Haho health district. The independent associated factors found were not living in couple (AOR=3.4; CI=[1.6-7.3]; p=0.002), not being adherent to ART (AOR=2.8; CI= [1.2-6.4]; p=0.015), being under ART for four years and less (AOR=2.4; CI= [1.1-5.3]; p=0.037) and having 50 years and less (AOR=6.4; CI=[1.4-30.2]; p=0.019). Healthcare practitioners implicated in the follow-up of HIV infected patients under treatment need to develop new strategies like reinforcing adherence to ART through communication, to improve outcome at an early stage.

Half-life time prediction of developing first-line antiretroviral treatment failure and its risk factors among TB and HIV co-infected children in Northwest Ethiopia; multi setting historical follow-up study

BackgroundEven though treatment failure is higher among TB and HIV infected children in a resource-limited setting, there is no prior evidence in general and in the study area in particular. Hence, this study was aimed at determining the half-life time prediction of developing first-line antiretroviral treatment failure and its risk factors among TB and HIV co-infected children.MethodsA historical follow-up study was employed among 239 TB and HIV co-infected children from January 2010-December 2020. The data was entered into Epi data version 4.2.2 and exported to STATA 14.0 Software for analysis. The Kaplan-Meier plot was used to estimate the half-life time to develop treatment failure. The required assumption was fulfilled for each predictor variable. Additionally, those variables having a p-value ≤0.25 in the bivariable analysis were fitted into a multivariable Cox-proportional hazards regression model. P-value, < 0.05 was used to declare a significant association.ResultsA total of 239 TB and HIV co-infected children were involved in this study. The overall half-life time to develop first treatment failure was found to be 101 months, with a total of 1027.8 years’ follow-up period. The incidence rate and proportion of developing first-line treatment failure were 5.5 per 100 PPY (Person-Year) [CI (confidence interval): 3.7, 6.9] 100 PPY and 23.8% (CI; 18.8, 29.7) respectively. Factors such as hemoglobin 10 mg/dl [AHR (Adjusted Hazard Ratio): 3.2 (95% CI: 1.30, 7.73), severe acute malnutrition [AHR: 3.8 (95% CI: 1.51, 79.65), World Health Organization stage IV [AHR: 2.4 (95% CI: 1.15, 4.93)], and cotrimoxazole prophylaxis non user [AHR: 2.3 (95% CI: 1.14, 4.47)] were found to be a risk factor to develop treatment failure.ConclusionIn this study, the half-life time to develop first-line treatment failure was found to be very low. In addition, the incidence was found to be very high. The presence of hemoglobin 10 mg/dl, severe acute malnutrition, World Health Organization stage, and non-use of cotrimoxazole prophylaxis were discovered to be risk factors for treatment failure. Further prospective cohort and qualitative studies should be conducted to improve the quality of care in paediatric ART clinics to reduce the incidence or burden of first line treatment failure among TB and HIV co-infected children.

Propilar Application For Drug Distribution Solutions For HIV / AIDS Patients

The HIV (Human Immunodeficiency Virus) virus is already known to be one of the deadly and very dangerous viruses. This virus attacks white blood cells so that the human immune system decreases and sufferers become susceptible to other diseases and experience complications.[1] Various symptoms that arise as a result of the HIV virus are called Acquired Immunodeficiency Syndrome (AIDS).[1] In Indonesia, the HIV virus case has become a concern of the government because of its increasing development.This HIV virus cannot be removed but can be suppressed by using antiretroviral drugs. Antiretroviral drugs work by suppressing the development of the virus until it reaches its lowest point so that the patient's immune system can function optimally. HIV / AIDS sufferers are required to take this medicine every day and should not be forgotten. Compliance with HIV/AIDS patients or commonly called ODHA is very important for the success of treatment.[2]In carrying out antiretroviral therapy treatment failure often occurs. This is caused by many factors that affect one of them sufferers often forget to take the medicine on time so that treatment fails.For this reason, the report will discuss the design of health applications as a reminder for HIV patients in taking antiretroviral drugs. Besides this application will help antiretroviral drugs better known to the wider community.

HIV-1 pretreatment drug resistance negatively impacts outcomes of first-line antiretroviral treatment.

Pretreatment drug resistance (PDR) prevalence in sub-Saharan Africa is rising, but evidence of its impact on efavirenz (EFV)-based antiretroviral treatment (ART) is inconclusive. We determined the impact of PDR on outcomes of EFV-based ART in a subanalysis of a randomized clinical trial comparing different ART monitoring strategies implemented at a rural treatment facility in Limpopo, South Africa. Participants initiating EFV-based first-line ART (2015-2017) were enrolled and received 96 weeks follow-up. Resistance to nucleos(t)ide reverse transcriptase inhibitors (NRTIs) and non-NRTI's (NNRTIs) was retrospectively assessed by population-based sequencing. Virological failure was defined as a viral load of at least 1000 copies/ml after at least 24 weeks of ART. A total of 207 participants were included, 60.4% (125/207) of whom were female. Median age was 38.8 (interquartile range: 31.4-46.7) years. Median CD4+ cell count was 191 (interquartile range: 70-355) cells/μl. PDR was detected in 12.9% (25/194) of participants with available sequencing results; 19 had NNRTI-resistance, and six had NRTI- and NNRTI-resistance. 26.0% of participants (40/154) with sequencing results and virological follow-up developed virological failure. PDR was independently associated with failure (adjusted hazard ratio: 3.7 [95% confidence interval: 1.68.5], P = 0.002). At failure, 87.5% (7/8) of participants with PDR harboured dual-class resistant virus, versus 16.7% (4/24) of participants without PDR (P = 0.0007). Virological resuppression after failure on first-line ART occurred in 57.7% (15/26) of participants without PDR versus 14.3% (1/7) of participants with PDR (P = 0.09). PDR was detected in 13% of study participants. PDR significantly increased the risk of virological failure of EFV-based ART. Accumulation of resistance at failure and inability to achieve virological resuppression illustrates the profound impact of PDR on treatment outcomes.
