Poor treatment outcomes of children on highly active antiretroviral therapy: protocol for a systematic review and meta-analysis.

ABSTRACT:

Introduction

While access to highly active antiretroviral therapy (HAART) for children with HIV has expanded and the use of HAART has substantially reduced the morbidity and mortality of children due to HIV, poor treatment outcomes among children with HIV are still a major public health problem globally. The aim of this systematic review and meta-analysis is to quantify treatment outcomes among children with HIV.

Methods and analysis

Systematic searches will be conducted in three electronic databases (PubMed, SCOPUS and Web of Science) for recent studies published from 01 Jan 2000 up to 28 October 2020, without geographical restriction. The primary outcomes of the study will be poor treatment outcomes, which include death, treatment failure and loss to follow-up. We will include quantitative studies that report treatment outcomes among children under the age of 18 years with HIV. Studies will be excluded if they are case report, case series, conducted among adults only or do not provide data on treatment outcomes for children. Two researchers will screen the titles and abstracts of all citations identified in our search, then review the full text of the remaining papers to identify those that meet the inclusion criteria. The Newcastle-Ottawa Scale will be used for quality assessment. A random-effects meta-analysis will be used to obtain pooled estimates of the proportion of poor treatment outcomes. The heterogeneity between studies will be checked visually by using forest plots and quantitatively measured by the index of heterogeneity (I²). Pooled estimates of poor treatment outcomes will be calculated with a random-effects model. Subgroup analysis will be conducted by study settings, treatment regimen, comorbidity (such as tuberculosis), study period and HIV type (HIV-1 and HIV-2).

Ethics and dissemination

Ethical approval will not be required for this study as it will be based on published papers. The final report of this review will be published in a peer-reviewed scientific journal.

Project description:INTRODUCTION:Directly observed therapy of highly active antiretroviral therapy (DOT-HAART) is a feasible adherence intervention. Prospective DOT-HAART studies have shown mixed results, and optimal target groups have yet to be defined. We performed a meta-analysis and systematic review to assess the effect of DOT-HAART on adherence and virologic and immunologic response. METHODS:We performed a comprehensive search through August 2009 to identify peer-reviewed controlled studies that involved outpatient DOT-HAART among adults and reported at least 1 outcome assessed in this meta-analysis. Random-effects meta-analyses were performed; differences in effect on virologic suppression were examined using stratified meta-analyses and meta-regression on several study characteristics. RESULTS:Seventeen studies met inclusion criteria. Compared with control groups, DOT-HAART recipients were more likely to achieve an undetectable viral load (random effects risk ratio 1.24, 95% confidence interval (CI): 1.08 to 1.41), a greater increase in CD4 cell count (random effects weighted mean difference 43 cells/microL, 95% CI: 12 to 74 cells/microL), and HAART adherence of > or =95% (random effects risk ratio 1.17, 95% CI: 1.03 to 1.32). Results varied with respect to virologic response. DOT-HAART did not have a significant effect on virologic suppression when restricted to randomized controlled studies. Post-treatment effect was not observed in a limited number of studies. CONCLUSIONS:DOT-HAART had a significant effect on virologic, immunologic, and adherence outcomes, although its efficacy was not supported when restricting analysis to randomized controlled trials. DOT-HAART shows greatest treatment effect when targeting individuals with greater risk of nonadherence and when delivering the intervention that maximizes participant convenience and provides enhanced adherence support. Further investigation is needed to assess the postintervention effect and cost-effectiveness of DOT-HAART.

Project description:ObjectivesOver 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.MethodsPubMed/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.ResultThe 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.ConclusionThe 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.

Project description:BackgroundMinimizing antiretroviral treatment failure is crucial for improving patient health and for maintaining long-term access to care in low-income settings such as eastern Africa. To develop interventions to support adherence, policymakers must understand the extent and scope of treatment failure in their programs. However, estimates of treatment failure in eastern Africa have been variable and inconclusive.ObjectiveThis systematic review and meta-analysis sought to determine the pooled prevalence of immunological failure among adults receiving antiretroviral therapy in eastern Africa.MethodsWe performed a systematic search of the PubMed, Google Scholar, Excerpta Medica Database, and the World Health Organization's Hinari portal (which includes the Scopus, African Index Medicus, and African Journals Online databases) databases. Unpublished studies were also accessed from conference websites and university repositories. We used Stata version 14 for data analysis. The Cochrane Q test and I 2 test statistic were used to test for heterogeneity across the studies. Due to high levels of heterogeneity, a random effects model was used to estimate the pooled prevalence of immunological failure. Begg and Egger tests of the intercept in the random effects model were used to check for publication bias.ResultsAfter removing duplicates, 25 articles remained for assessment and screening. After quality screening, 15 articles were deemed eligible and incorporated into the final analysis. The average pooled estimate of immunological treatment failure prevalence was found to be 21.89% (95% CI, 15.14-28.64). In the subgroup analysis conducted by geographic region, the pooled prevalence of immunological treatment failure in Ethiopia was 15.2% (95% CI, 12.27-18.13) while in Tanzania it was 53.93% (95% CI, 48.14-59.73). Neither the results of Egger test or Begg tests suggested publication bias; however, on visual examination, the funnel plot appeared asymmetric. The large heterogeneity across the studies could be explained by study country.ConclusionImmunological treatment failure among patients receiving antiretroviral therapy in eastern Africa was high, and greater than previously reported. The relatively low rates of treatment failure found in Ethiopia suggest that its health extension program should be studied as a model for improving adherence in the region.

Project description:Despite effectiveness of antiretroviral therapy in reducing mortality of opportunistic infections among HIV infected children, however tuberculosis (TB) remains a significant cause for morbidity and attributed for one in every three deaths. HIV-infected children face disproportionate death risk during co-infection of TB due to their young age and miniatures immunity makes them more vulnerable. In Ethiopia, there is lack of aggregated data TB and HIV mortality in HIV infected children. We conducted an extensive systematic review of literature using Preferred Reporting of Systematic Review and Meta-Analysis (PRISMA) guideline. Five electronic databases were used mainly Scopus, PubMed, Medline, Web of Science, and Google scholar for articles searching. The pooled proportion of TB was estimated using a weighted inverse variance random-effects meta-regression using STATA version-17. Heterogeneity of the articles was evaluated using Cochran's Q test and I2 statistic. Subgroup analysis, sensitivity test, and Egger's regression were conducted for publication bias. This met-analysis is registered in Prospero-CRD42024502038. In the final met-analysis report, 13 out of 1221 articles were included and presented. During screening of 6668 HIV-infected children for active TB occurrence, 834 cases were reported after ART was initiated. The pooled proportion of active TB among HIV infected children was found 12.07% (95% CI: 10.71-13.41). In subgroup analysis, the Oromia region had 15.6% (95%CI: 10.2-20.6) TB burden, followed by southern Ethiopia 12.8% (95%CI: 10.03-15.67). During meta-regression, missed isoniazid Preventive therapy (IPT) (OR: 2.28), missed contrimoxazole preventive therapy (OR: 4.26), WHO stage III&IV (OR: 2.27), and level of Hgb ≤ 10gm/dl (OR = 3.11.7) were predictors for active TB. The systematic review found a higher proportion of active TB in HIV-infected children in Ethiopia compared to estimated rates in end TB strategy. To prevent premature death during co-infection, implement effective TB screening and cases tracing strategies in each follow up is needed.

Project description:Cryptococcal meningitis (CM) is the proximate cause of death in 20%-30% of persons with acquired immunodeficiency syndrome in Africa.Two prospective, observational cohorts enrolled human immunodeficiency virus (HIV)-infected, antiretroviral-naive persons with CM in Kampala, Uganda. The first cohort was enrolled in 2001-2002 (n = 92), prior to the availability of highly active antiretroviral therapy (HAART), and the second was enrolled in 2006-2007 (n = 44), when HAART was available.Ugandans presented with prolonged CM symptoms (median duration, 14 days; interquartile range, 7-21 days). The 14-day survival rates were 49% in 2001-2002 and 80% in 2006 (P < .001). HAART was started 35 +/- 13 days after CM diagnosis and does not explain the improved 14-day survival rate in 2006. In 2006-2007, the survival rate continued to decrease after hospitalization, with only 55% surviving to initiate HAART as an outpatient. Probable cryptococcal-related immune reconstitution inflammatory syndrome occurred in 42% of patients, with 4 deaths. At 6 months after CM diagnosis, 18 persons (41%) were alive and receiving HAART in 2007. The median cerebral spinal fluid (CSF) opening pressure was 330 mm H(2)O; 81% of patients had elevated pressure (>200 mm H(2)O). Only 5 patients consented to therapeutic lumbar puncture. There was a trend for higher mortality for pressures >250 mm H(2)O (odds ratio [OR], 2.1; 95% confidence interval [CI], 0.9-5.2; P = .09). Initial CSF WBC counts of <5 cells/mL were associated with failure of CSF sterilization (OR, 17.3; 95% CI, 3.1-94.3; P < .001), and protein levels <35 mg/dL were associated with higher mortality (OR, 2.0; 95% CI, 1.2-3.3; P = .007).Significant CM-associated mortality persists, despite the administration of amphotericin B and HIV therapy, because of the high mortality rate before receipt of HAART and because of immune reconstitution inflammatory syndrome-related complications after HAART initiation. Approaches to increase acceptance of therapeutic lumbar punctures are needed.
