Factors Affecting Virological Failure in Children Receiving First-Line Antiretroviral Therapy in Ethiopian Healthcare Facilities: A Retrospective Analysis. Pediatric Health Med Ther 2024; 15:171-180. [PMID: 38765900 PMCID: PMC11100487 DOI: 10.2147/phmt.s452150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 05/09/2024] [Indexed: 05/22/2024] Open
Abstract
Background The causes of virological failure are poorly recognized and investigated. This study aimed to identify determinant factors of viral failure in children taking first-line ART at a randomly selected federal hospital in Addis Ababa, Ethiopia. Methods A facility-based unmatched case-control study was carried out from May 10, 2022, to July 20, 2022, G.C. among HIV-infected children on first-line antiretroviral therapy. There were 209 HIV-positive youngsters in the study's overall sample size, comprising 53 cases and 156 controls. Data was gathered by chart review using an organized checklist in English. The data were entered using Epi-data 4.2 and exported into SPSS version 24 for analysis. The relationship between each explanatory variable and the result variable was described using both bivariate and multivariate analysis. An adjusted odds ratio with 95% confidence intervals was conducted, and a p-value <0.05 was considered statistically significant. Results Being male (AOR= 4.504; 95% CI: 1.498, 13.539), duration on ART exceeding 47 months (AOR=40.6; 95% CI:9.571,172.222), fair and poor drug adherence (AOR=16.348; 95% CI:4.690,56.990), missed clinical appointments (AOR = 3.177; 95% CI: 1.100-9.174), and baseline WHO clinical stage 4 disease (AOR = 6.852; 95% CI: 1.540-30.49) were associated with an increased risk of virological failure. Conversely, a history of drug change and a CD4 count ranging from 250 to 500 cells/mm3 were significantly protective factors (AOR = 0.071; 95% CI: 0.024-0.214 and AOR=0.118; 95% CI: 0.030, 0.464, respectively). Conclusion Being male, duration on ART >47 months, fair and poor adherence, missed clinical appointments, and baseline WHO Stage 4 are factors that increase the odds of virological failure. History of ART Drug change and a CD4 count between 250 and 500 cells/mm3 are factors that decrease the odds of virological failure.

Incidence and predictors of virological failure among children receiving first-line anti-retroviral treatment in public comprehensive specialized hospitals found in Northeast Ethiopia: a retrospective follow-up study. Front Pediatr 2024; 12:1249957. [PMID: 38516356 PMCID: PMC10954832 DOI: 10.3389/fped.2024.1249957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 02/20/2024] [Indexed: 03/23/2024] Open
Abstract
Background Despite anti-retroviral treatment coverage in resource-limited countries being highly appreciated, the occurrence of first-line virological failure remains a priority agenda. Therefore, this study serves as an input for evidence of virological failure among children. Objective This study aimed to assess the incidence and predictors of virological failure among children receiving first-line anti-retroviral treatment in public comprehensive specialized hospitals found in Northeast Ethiopia through a retrospective follow-up study. Methods A multicenter institution-based retrospective follow-up study was conducted on the medical records of 481 human immunodeficiency virus (HIV)-infected children who were on first-line anti-retroviral therapy from 1 January 2017 to 31 December 2021. Data were retrieved from 15 May to 15 June 2022 at three public comprehensive specialized hospitals. Study participants were recruited using a simple random sampling technique. STATA-14 was used to analyze the data, which was entered using EpiData version 4.6.2.0. The Kaplan-Meier estimator was used to estimate the survival. Both bivariable and multivariable Cox regression models were fitted to identify predictors. Finally, adjusted hazards ratios (AHRs) with 95% confidence intervals (CIs) were computed, and variables with a P-value of <0.05 were considered statistically significant predictors of virological failure. Result A total of 481 children records were included in the final analysis, with an observed follow-up period of 16,379 person-months. Among these, 60 (12.47%) had developed virological failure, resulting in an overall incidence density rate of 3.67 (95% CI; 2.84, 4.73) per 1000 person-month observations. The hazards of virological failure (VF) among children were found to be increased by being in recent WHO stages III and IV (AHR = 3.688; 95% CI: 1.449-6.388), poor adherence to anti-retroviral treatment (ART) (AHR = 3.506; 95% CI: 1.711-7.234), and living in a rural environment (AHR = 5.013; 95% CI: 1.958-8.351). Conversely, the hazard of VF was reduced by 60% when the age of caregivers was less than 40 years (AHR = 0.405; 0.003-0.449). Conclusion and recommendations The incidence rate of virological failure was relatively high. Living in a rural area, poor adherence to ART, being in a recent advanced WHO clinical stage, and having a caregiver of 40 years of age or older were all independent predictors of virological failure in children. Patients or parents (caregivers) need to be aware of the importance of strictly adhering to treatment regimens to prevent virological failure.

Abstract
OBJECTIVES To characterize HIV drug resistance (HIVDR) below and above the WHO threshold of 1000 copies/mL, considered for the definition of HIV ART failure in resource-limited settings. METHODS From a cohort of 280 adolescents (aged 10-19 years) receiving ART for at least 6 months, genotypic resistance testing (GRT) was attempted for two groups of participants: participants with low-level viraemia [LLV; viral load (VL) 200-999 copies/mL] and those in virological failure (VF; confirmed VL ≥1000 copies/mL) using an in-house method. The Stanford HIValg Program was used to identify relevant HIVDR mutations and predict the efficacy of the newly introduced tenofovir-lamivudine-dolutegravir combination. RESULTS GRT was successfully performed in 54/58 (93.1%) eligible participants, of which 28/31 (90.3%) were in VF and 26/27 (96.3%) had LLV. A high level of resistance was found both in adolescents with LLV and those in VF, with respectively 84.6% (22/26) and 75.0% (21/28) of participants harbouring at least one HIVDR mutation. NRTIs and NNRTIs were the most affected drug classes in both population groups. In contrast, PIs were not significantly affected and dolutegravir was expected to be active for all participants tested. However, for the newly introduced dolutegravir-based combination, functional monotherapy (dolutegravir only) was potentially possible for 22.7% (5/22) of the participants with LLV. CONCLUSIONS Our findings show that the 1000 copies/mL threshold is not an indicator of virological success and we call for a revision of the current WHO definition of VF in resource-limited countries.

Abstract
Virological response to antiretroviral therapy (ART) remains a challenge for HIV-infected children and adolescents due to non-optimization of pediatric ART for resource-limited settings. In this study, we aimed to investigate factors associated with virologic failure (VF) in HIV-infected-children and adolescents on ART in Cameroon. A prospective patient-based cohort study was conducted among HIV-infected children (0-9 years) and adolescents (10-19 years) followed-up between November 2018 and October 2019 in 38 healthcare centers located in the Littoral region of Cameroon. The 1st viral load (VL) was assessed after 6 months of ART initiation and the 2nd VL between 3 and 6 six months later in patients with VL ≥1000 copies/ml in accordance with the national algorithm using Abbott Real-Time HIV-1 Viral Load Assay. Multivariate analyses were performed to identify the determinants of higher risk of VF. Of 1,029 HIV-infected children and adolescents (393 children and 636 adolescents), 801 (77.8%) cumulatively presented with VL <1000 copies/mL within 12 months on ART. Adolescents were more likely to have VF than children (24.5% vs 18.3%, OR: 1.39; 95%CI: 1.00-1.93; p = 0.047). Patients followed-up in decentralized care units were significantly more likely to have VF compared to those attending the accredited treatment centers (26.1% vs 16.6%, OR: 1.88, 95%CI: 1.37-2.58; p<0.001). Our findings show a high rate of VL suppression (VLS, 77.8%) among HIV-infected children and adolescents, albeit lower than the established target of 90%. Being adolescent and patients followed in the decentralized care units are high risk factors for VF, thereby necessitating routine therapeutic education of patients and guardians in resource limited countries to improve VLS.

Abstract
Due to the efficacy of antiretrovirals (ARVs), mortality and morbidity related to the AIDS epidemic has declined considerably in recent decades. Nevertheless in Africa, the persistence of new infections and the concerning development of ARV drug resistance reflect the challenges in preventing and treating HIV infection. These problems are especially affecting children and adolescents living with HIV (CALHIV). In 1998, Senegal was the first West African country to implement a government program for access to ARV drugs. However, care for CALHIV remains challenging. A national survey conducted in 2015 showed that 64% of CALHIV (0-19 years) in follow-up in sites outside of Dakar were in treatment failure. The article presents the results of an anthropological study that aims to examine the modalities of medical and social care for CALHIV, identify the various structural and social determinants of treatment failure or success, and ascertain their respective influence. The ethnographic survey was conducted between July 2020 and November 2021 in 11 of the 14 regions of Senegal and in 15 health facilities (11 health centers and 4 regional hospitals). The interviews and observations were conducted with 65 children and adolescents, 63 parents or guardians, and 47 health workers providing their care. The results show that situations of treatment failure or success are the result of favorable or unfavorable configurations that bring into play various actors-children, parents, health care professionals-and their interactions with and in varying sociocultural and structural contexts. This research underscores the contribution of anthropology to the analysis and understanding of care systems. From a public health perspective, our analyses argue for a differentiated approach to strengthening the skills of health facility staff, taking into account the specificity of each site.

Abstract
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.

Abstract
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.

Rate of virological failure and HIV-1 drug resistance among HIV-infected adolescents in routine follow-up on health facilities in Cameroon. PLoS One 2022; 17:e0276730. [PMID: 36288365 PMCID: PMC9604952 DOI: 10.1371/journal.pone.0276730] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 10/12/2022] [Indexed: 11/17/2022] Open
Abstract
The objective of this study was to determine the rates of virological failure (VF) and HIV drug resistance (HIVDR) amongst adolescents on antiretroviral Therapy (ART). A retrospectively designed study was conducted in 10 healthcare centers for adolescents living with HIV (ALHIV) in the two main cities of Cameroon (Yaoundé and Douala), from November 2018 to May 2019. Sociodemographic, clinical, therapeutic and laboratory parameters were collected from medical records. All enrolled ALHIV had viral load (VL) measurements following the national guidelines. All patients with a VL ≥ 1000 copies/ml were called to perform genotyping tests. The chi-square test was used to determine the factors associated with VF. Out of the 1316 medical records of ALHIV, we included 1083 ALHIV having a VL result. Among them, 276 (25.5%) were experiencing VF, and VF was significantly higher in ALHIV with suboptimal adherence (p<0.001), older adolescents (p<0.05), those who lived outside the city where they were receiving ART (p<0.006), severely immunocompromised (p<0.01) and started ART at infancy (p<0.02). Among the 45/276 (16.3%) participants with an available genotyping resistance testing (GRT) result, the overall rate of HIVDR was 93.3% (42/45). The most common mutations were K103N (n = 21/42, 52.3%) resulting in high-level resistance to Efavirenz and Nevirapine, followed by M184V (n = 20/42, 47.6%) and thymidine analog mutations (n = 15/42, 35.7%) associated with high-level resistance to Lamivudine and Zidovudine respectively. The high rate of VF and HIVDR among ALHIV regularly followed in health facilities in Cameroon highlights the need to develop interventions adapted to an adolescent-centered approach to preserve future ART options.

BMC Public Health 2022; 22:1203. [PMID: 35710413 PMCID: PMC9202111 DOI: 10.1186/s12889-022-13504-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 05/24/2022] [Indexed: 11/10/2022] Open
Abstract
Background In 2016, we conducted a systematic review to assess the feasibility of treatment monitoring for people living with HIV (PLHIV) receiving antiretroviral therapy (ART) in low and middle-income countries (LMICs), in line with the 90-90-90 treatment target. By 2020, global estimates suggest the 90-90-90 target, particularly the last 90, remains unattainable in many LMICs. This study aims to review the progress and identify needs for public health interventions to improve viral load monitoring and viral suppression for PLHIV in LMICs. Methods A literature search was conducted using an update of the initial search strategy developed for the 2016 review. Electronic databases (Medline and PubMed) were searched to identify relevant literature published in English between Dec 2015 and August 2021. The primary outcome was initial viral load (VL) monitoring (the proportion of PLHIV on ART and eligible for VL monitoring who received a VL test). Secondary outcomes included follow-up VL monitoring (the proportion of PLHIV who received a follow-up VL after an initial elevated VL test), confirmation of treatment failure (the proportion of PLHIV who had two consecutive elevated VL results) and switching treatment regimen rates (the proportion of PLHIV who switched treatment regimen after confirmation of treatment failure). Results The search strategy identified 1984 non-duplicate records, of which 34 studies were included in the review. Marked variations in initial VL monitoring coverage were reported across study settings/countries (range: 12–93% median: 74% IQR: 46–82%) and study populations (adults (range: 25–96%, median: 67% IQR: 50–84%), children, adolescents/young people (range: 2–94%, median: 72% IQR: 47–85%), and pregnant women (range: 32–82%, median: 57% IQR: 43–71%)). Community-based models reported higher VL monitoring (median: 85%, IQR: 82-88%) compared to decentralised care at primary health facility (median: 64%, IRQ: 48-82%). Suboptimal uptake of follow-up VL monitoring and low regimen switching rates were observed. Conclusions Substantial gaps in VL coverage across study settings and study populations were evident, with limited data availability outside of sub-Saharan Africa. Further research is needed to fill the data gaps. Development and implementation of innovative, community-based interventions are required to improve VL monitoring and address the “failure cascade” in PLHIV on ART who fail to achieve viral suppression.

Treatment failure and its associated factors among children receiving highly active antiretroviral therapy in Ethiopia: A systematic review and meta-analysis. SAGE Open Med 2022; 10:20503121221081335. [PMID: 35251655 PMCID: PMC8891854 DOI: 10.1177/20503121221081335] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 01/28/2022] [Indexed: 01/22/2023] Open
Abstract
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.

HIV AIDS (Auckl) 2021; 13:1035-1044. [PMID: 34934365 PMCID: PMC8684387 DOI: 10.2147/hiv.s334067] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Accepted: 11/29/2021] [Indexed: 11/23/2022] Open
Abstract
Background Viral load monitoring is a golden indicator for diagnosing treatment failure in patients with HIV. HIV-infected children are considered a priority group for routine viral load monitoring. Globally, the World Health Organization recommends 95% of HIV patients have viral suppression. Factors leading to virological failure are not well understood and studied. This study aimed to determine virological failure among HIV-infected children on first-line antiretroviral therapy in the West Gojjam Zone, Amhara region. Ethiopia. Methods An institutional-based unmatched case–control study was carried out from October 1 to October 15, 2020, among HIV-infected children on first-line antiretroviral therapy. The study included 94 cases and 276 controls, with a total sample size of 370 out of 378 HIV-infected children. A structured English version checklist was used to collect data through chart review. The data were entered using Epi-data 4.2 and exported into SPSS version 20 for analysis. Descriptive statistics were conducted to summarize the sample characteristics. Bivariate and multivariate analyses were used to describe each explanatory variable’s association with the outcome variable. A bivariate analysis with a p-value < 0.25 was selected for multivariate analysis. Adjusted odds ratio with 95% confidence intervals was conducted, and p-value < 0.05 was considered statistically significant. Results Non-disclosure (AOR = 4.26; 95% CI: 2.09, 8.70), baseline viral load >1000 copies/mL (AOR = 10.82; 95% CI: 5.4, 21.67), recent poor adherence (AOR, 6.05, 95% CI, 1.70, 21.55) and missed clinical appointments (AOR = 8.03; 95% CI: 3.88, 16.65) were factors independently associated with virological failure. Conclusion Disclosure of HIV status of patients early, according to their age and adherence to counseling, should be emphasized. Efforts should be strengthened to trace back for missed clinical appointments and strictly follow-up with antiretroviral (ARV) medication for a baseline viral load >1000 copies/mL that helps to boost immunity and suppress viral replication.

Drug Resistance Mutations Among South African Children Living With HIV on WHO-recommended ART Regimens. Clin Infect Dis 2021; 73:e2217-e2225. [PMID: 32735012 DOI: 10.1093/cid/ciaa1068] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Children living with human immunodeficiency virus (HIV) (CLHIV) receiving antiretroviral therapy (ART) in resource-limited settings are susceptible to high rates of acquired HIV drug resistance (HIVDR), but few studies include children initiating age-appropriate World Health Organization (WHO)-recommended first-line regimens. We report data from a cohort of ART-naive South African children who initiated first-line ART. METHODS ART-eligible CLHIV aged 0-12 years were enrolled from 2012 to 2014 at 5 public South African facilities and were followed for up to 24 months. Enrolled CLHIV received standard-of-care WHO-recommended first-line ART. At the final study visit, a dried blood spot sample was obtained for viral load and genotypic resistance testing. RESULTS Among 72 successfully genotyped CLHIV, 49 (68.1%) received ABC/3TC/LPV/r, and 23 (31.9%) received ABC/3TC/EFV. All but 2 children on ABC/3TC/LPV/r were <3 years, and all CLHIV on ABC/3TC/EFV were ≥3 years. Overall, 80.6% (58/72) had at least one drug resistance mutation (DRM). DRMs to nonnucleoside reverse transcriptase inhibitors (NNRTIs) and nucleoside reverse transcriptase inhibitors (NRTIs) were found among 65% and 51% of all CLHIV, respectively, with no statistical difference by ART regimen. More CLHIV on ABC/3TC/EFV, 47.8% (11/23), were found to have 0 or only 1 effective antiretroviral drug remaining in their current regimen compared to 8.2% (4/49) on ABC/3TC/LPV/r. CONCLUSIONS High levels of NNRTI and NRTI DRMs among CLHIV receiving ABC/3TC/LPV/r suggests a lasting impact of failed mother-to-child transmission interventions on DRMs. However, drug susceptibility analysis reveals that CLHIV with detectable viremia on ABC/3TC/LPV/r are more likely to have maintained at least 2 effective agents on their current HIV regimen than those on ABC/3TC/EFV.

Abstract
BACKGROUND Virological failure is under-recognized issue among children living with human immunodeficiency virus in developing countries. This partly may lead to failure to achieve the global goal of 90-90-90 targets in most developing countries including Ethiopia. OBJECTIVES This study aimed to assess the virological failure and its predictors among children receiving antiretroviral therapy at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia. METHODS An institutional based cross-sectional study was conducted among 253 study cohorts from January 2020-April 2021. Socio-demographic characteristics were collected using a structured questionnaire via a face-to-face interview, while detailed clinical data of the children were collected by reviewing the medical record. About 5 ml of blood were collected for the analysis of complete blood count and viral load quantification. Data were analyzed using SPSS version 20 and variables at p-value < 0.05 in the multivariable analysis were considered as statistically significant. RESULTS In this study, the viral load suppression rate among antiretroviral therapy experienced children was 68.8%. Meanwhile, the overall virological failure among study participants was 19.4%. Children living without family (AOR = 3.63; 95%CI: 1.27-10.24), children with unemployed family (AOR = 4.95; 95%CI: 1.74-14.12), being wasted (AOR = 3.02; 95%CI: 1.19-7.67) being stunted (AOR = 2.38;95%CI:1.03-5.46), anemia (AOR = 5.50:95%CI;1.37-22.04) and being lymphopenic (AOR = 2.69:95%CI;1.04-7.75) were significantly associated with virological failure among children under treatment. CONCLUSION Higher virological failure among children was noteworthy in the present study. Caretakers other than immediate family, unemployed family, wasted, stunted, anemia, and lymphopenia were significant independent predictors of virological failure. Hence, standard, and optimal management of children under treatment should be warranted.

Abstract
Human immunodeficiency virus (HIV) drug resistance (HIVDR) is widespread in sub-Saharan Africa. Children and pregnant women are particularly vulnerable, and laboratory testing capacity remains limited. We, therefore, used a cross-sectional design and convenience sampling to characterize HIV subtypes and resistance-associated mutations (RAMs) in these groups in Sierra Leone. In total, 96 children (age 2-9 years, 100% ART-experienced), 47 adolescents (age 10-18 years, 100% ART-experienced), and 54 pregnant women (>18 years, 72% ART-experienced) were enrolled. Median treatment durations were 36, 84, and 3 months, respectively, while the sequencing success rates were 45%, 70%, and 59%, respectively, among children, adolescents, and pregnant women. Overall, the predominant HIV-1 subtype was CRF02_AG (87.9%, 95/108), with minority variants constituting 12%. Among children and adolescents, the most common RAMs were M184V (76.6%, n = 49/64), K103N (45.3%, n = 29/64), Y181C/V/I (28.1%, n = 18/64), T215F/Y (25.0%, n = 16/64), and V108I (18.8%, n = 12/64). Among pregnant women, the most frequent RAMs were K103N (20.6%, n = 7/34), M184V (11.8%, n = 4/34), Y181C/V/I (5.9%, n = 2/34), P225H (8.8%, n = 3/34), and K219N/E/Q/R (5.9%, n = 2/34). Protease and integrase inhibitor-RAMs were relatively few or absent. Based on the genotype susceptibility score distributions, 73%, 88%, and 14% of children, adolescents, and pregnant women, respectively, were not susceptible to all three drug components of the WHO preferred first-line regimens per 2018 guidelines. These findings suggest that routine HIVDR surveillance and access to better ART choices may improve treatment outcomes in Sierra Leone.

Abstract
Background HIV testing and treatment guidelines for children in sub-Saharan Africa have evolved over time, such that children are now treated at younger ages. The objective of this study was to describe the treatment experience for immunologic, virologic, and growth outcomes among HIV-infected Zambian children younger than 5 years of age from 2008 to 2018. Methods Participants enrolled in a clinical cohort study in Macha, Zambia and initiating antiretroviral treatment before 5 years of age between 2008 and 2015 were included in the analysis and followed up to the end of 2018. Outcomes, including growth, CD4+ T-cell percentage, viral suppression, and mortality, were evaluated among all children using longitudinal and survival analyses. Comparisons by age at treatment initiation (< 1, 1 to < 2, and 2 to < 5 years) were also evaluated. Results Three hundred eighty-one children initiating treatment before 5 years of age between 2008 and 2015 were included in the analysis. Growth metrics and CD4+ T-cell percentage improved over time after treatment initiation. However, 20% of children remained underweight and 40% of children remained stunted after the first 36 months of treatment. 85% of children had a viral load < 400 copies/mL after 12 months of treatment. However, children < 1 year at treatment initiation were more likely to have a detectable viral load in the first 12 months of treatment and less likely to achieve viral suppression compared to older children. Mortality was highest in the first 12 months of treatment, among underweight children, and among children initiating treatment in 2008–2010 compared to 2011–2015. Conclusions Most children initiating antiretroviral treatment from 2008 to 2015 in rural Zambia responded well to treatment. However, many children remained underweight and stunted, and experienced high mortality rates during the first few months of treatment. This supports continued efforts to improve early infant diagnosis, nutritional support, and pediatric drug formulations.

Abstract
BACKGROUND The feasibility of antiretroviral therapy (ART) monitoring remains problematic in decentralized HIV clinic settings of sub-Saharan Africa. We assessed the rates and correlates of HIV-1 virological failure (VF) and drug resistance (DR) in 2 pre-test-and-treat urban clinic settings of Senegal. METHODS Consenting HIV-1-infected adults (⩾18 years) receiving first-line ART for ⩾12 months were cross-sectionally enrolled between January and March 2015, at the referral outpatient treatment center of Dakar (n = 151) and decentralized regional hospital of Saint-Louis (n = 127). In the 12 months preceding plasma specimens' collection patients at Saint-Louis had no viral load (VL) testing. Significant predictors of VF (VL ⩾ 1000 copies/ml) and DR (clinically relevant mutations) were determined using binomial logistic regression in R software. RESULTS Of the 278 adults on EFV-/NVP-based regimens, 32 (11.5% [95%CI: 8.0-15.9]) experienced VF. Failing and non-failing patients had comparable median time [interquartile] on ART (69.5 [23.0-89.5] vs 64.0 [34.0-99.0] months; P = .46, Mann-Whitney U-test). Of the 27 viraemic isolates successfully genotyped, 20 (74.1%) carried DR mutations; most frequent were M184VI (55.6%), K103N (37.1%), thymidine analog mutations (29.6%), Y181CY (22.2%). The pattern of mutations did not always correspond to the ongoing treatment. The adjusted odds of VF was significantly associated with the decentralized clinic site (P < .001) and CD4 < 350 cells/mm3 (P < .006). Strong correlates of DR also included Saint-Louis (P < .009), CD4 < 350 cells/mm3 (P <. 001), and nevirapine-based therapies (comparator: efavirenz-based therapies; P < .027). In stratification analyses by site, higher rate of VF at Saint-Louis (20.5% [95%CI: 13.8-28.5] vs 4.0% [95%CI: 1.5-8.5] in Dakar) was associated with nevirapine-based therapies (OR = 3.34 [1.07-11.75], P = .038), self-reported missing doses (OR = 3.30 [1.13-10.24], P = .029), and medical appointments (OR = 2.91 [1.05-8.47], P = .039) in the last 1 and 12 months(s), respectively. The higher rate of DR at Saint-Louis (12.9% [95%CI: 7.6-20.1] vs 2.7% [95%CI: 0.7-6.7] in Dakar) was associated with nevirapine-based therapies (OR = 5.13 [1.12-37.35], P = .035). CONCLUSION At decentralized urban settings, there is need for enhanced virological monitoring and adherence support. HIV programs in Senegal should intensify early HIV diagnosis for effective test-and-treat. These interventions, in addition to the superiority of efavirenz-based therapies provide a favorable framework for transitioning to the recommended potent drug dolutegravir, thereby ensuring its long-term use.

HIV AIDS-RESEARCH AND PALLIATIVE CARE 2021; 13:229-237. [PMID: 33664596 PMCID: PMC7921627 DOI: 10.2147/hiv.s294046] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 02/08/2021] [Indexed: 11/23/2022]
Abstract
Background HIV/AIDS-associated morbidity and mortality have reduced since the introduction of antiretroviral therapy (ART). Treatment failure is one of the causes of mortality, morbidity, and the development of drug-resistant viral strains. Therefore, this research aims to assess the prevalence and associated factors of treatment failure among children with HIV/AIDS on antiretroviral therapy attending the University of Gondar Specialized Referral Hospital, Northwest Ethiopia. Methods A retrospective study was conducted on 200 children registered for ART from 2005 to 2017. Data regarding patients’ socio-demographic, baseline clinical characteristics, and treatment-related information were collected through a review of their medical records. Data were entered into Epi-info version 3.5.3 and analyzed using statistical package for social sciences (SPSS) version 21 software. To summarize characteristics of the study participant’s descriptive statistics were done. Bivariable and multivariable binary logistic regression were fitted to identify factors associated with treatment failure. The odds ratio and 95% confidence interval (CI) were calculated to assess the strength of the association and P-value<0.05 in the multivariable regression was considered as statistically significant. Results The prevalence of ART failure was 12.5% (95% CI: 7.88, 17.12), clinical failure was the most common followed by immunologic failure with only a small proportion having both clinical and immunologic failure. The mean time to develop treatment failure after initiation of the first-line regimen was 22.28 ± 24.00 months. Being male (AOR= 3.15; 95% CI: 1.18–8.39), co-infected with tuberculosis (TB) at baseline (AOR= 2.37; 95% CI: 1.23–8.84), being on ART for a long period (>36 months) (AOR= 1.01; 95% CI: 1.34–2.89), and regimen change (AOR=9.22; 95% CI: 3.36–25.03) were factors of ART failure. Conclusion In this study, there is significant treatment failure among HIV-infected children. Having co-infection, being on ART for a long period, regimen change, and being male were found to be independent factors of treatment failure in children. Therefore, timely identification and monitoring of ART failure should be necessary to enhance the benefit and to prevent further complications. Prophylaxis for opportunistic infections such as co-trimoxazole preventive therapy should continue to recover the immunological status of the child.

Abstract
BACKGROUND AND AIMS Sub-Saharan Africa (SSA) is the region with the most patients co-infected with the human immunodeficiency virus (HIV) and the hepatitis B virus (HBV) worldwide. However, few studies have focused on SSA children who are at a higher risk of developing a chronic infection than adults. Furthermore, children on first-line antiretroviral therapy (ART) including low genetic barrier drugs may develop both HBV and HIV resistance mutations. The aim of this work was to document HIV-HBV co-infection and to characterize the HBV isolates in children in Senegal. METHODS This is a retrospective study of 613 children infected with HIV on ART or not. Dried blood spot (DBS) specimens were used to detect hepatitis B surface antigen (HBsAg) with a rapid diagnostic test (RDT). Confirmation of HBsAg status and hepatitis B e antigen (HBeAg) detection was performed on an automated platform using the chemiluminescence assay technology. HBV viral DNA was quantified by real-time polymerase chain reaction (PCR) and the preS1/preS2/HBsAg region was genotyped by nested PCR followed by sequencing using the Sanger technique. RESULTS The prevalence of HIV-HBV co-infection was 4.1% (25/613). The median age of co-infected children was 13 years (2 years-16 years) and 40% (10/25) were girls. Almost all 19/20 (95%) were infected with HIV-1 and 79% (19/24) were treated with 3TC-based triple combination ART. The median duration of time on ART was 15 months (3 months-80 months). More than half of the children 53% (9/17) were experiencing HIV virologic failure and 75% (6/8) had at least one HIV-related resistance-associated mutation (RAM). Of the six children with resistance, none of the three administered treatments were effective on HIV. Of the 25 co-infected children, 82% (18/22) were HBeAg-positive, while the median HBV viral load (VL) was 6.20 log10 IU/mL (24/25 patients), and 62,5% (10/16) of the children had a persistent HBV viremia. Combination of ART was the only factor associated with HBV viremia persistence. Amplification was successful in 15 out of 16 patients (rate of 94%), and the ensuing phylogenetic analysis revealed that eight strains (53%) belonged to genotype A and seven (47%) to genotype E. HBV-related 3TC RAMs were uncovered in 20% of these patients (3/15). HBsAg escape mutations were found in 20% of the children (3/15). CONCLUSIONS Our results showed a high level of drug resistance mutations to both HIV and HBV, a significant level of HBsAg escape mutations, HBV DNA persistence and HIV virologic failure in co-infected children in Senegal. The HBV genotypes found were A and E.

Abstract
Treatment scale-up is leading to a progressive increase in HIV resistance to antiretrovirals, especially in children. To assess resistance to reverse transcriptase inhibitors (RTIs) in HIV-1 infected children in Côte d'Ivoire, genotypic resistance tests were performed and interpreted using the ANRS algorithm (www.hivfrenchresistance.org). Phylogenetic trees were created using BioEdit v7 and Mega7 software. The frequency of resistance to at least one RTI was 79%. It was 88% for nucleoside reverse transcriptase inhibitors (NRTIs), 71% for non-nucleoside reverse transcriptase inhibitors (NNRTIs), and 63% for both classes (NRTI + NNRTI). The frequency of resistance was 50% for the ZDV + 3TC + EFV combination, 42% for the ABC + 3TC + EFV combination, and 8% for the TDF + 3TC + EFV combination. Frequently encountered resistance mutations were for NRTIs: M184V (88%), TAMs (67%), T215F/I/V/Y (33%), and L74I/V (24%); for NNRTIs: K103N/S (74%), P225H (26%), and G190A/E/Q (24%). The synthesis of phylogenetic analyses showed the predominance of the viral subtype CRF02_AG (85%). These results show a high prevalence of resistance to RTIs in children infected with HIV-1. Hence the interest of a more accessible monitoring of viral load and genotypic resistance tests in HIV-1 infected children undergoing treatment in Côte d'Ivoire.
