Viral failure in hiv childrens

BACKGROUND: Adolescents living with HIV (ALHIV) experience higher mortality and are more likely to have poor antiretroviral therapy (ART) adherence and unsuppressed viral load (VL) compared to adults. Enhanced adherence counseling (EAC) is a client-centered counseling strategy that aims to identify and address barriers to optimal ART use and can be tailored to the unique needs of adolescents. This study aimed to better understand adherence barriers among ALHIV with suspected treatment failure and their experience with EAC to inform future programming...

Myocarditis is an inflammatory disease of the myocardium with focal or diffuse involvement. Viral infections are the most common cause of myocarditis, especially in Western countries. A recent viral illness with gastroenteric or upper respiratory symptoms often precedes myocarditis. The absence of specific pathognomonic features in conjunction with the wide spectrum of clinical manifestations that range from subclinical cases to sudden cardiac death (SCD) makes myocarditis diagnosis particularly challenging...

Mutations in the ARPC1B isoform component of human actin-related protein 2/3 complex have been recently associated with an inborn error of immunity characterized by combined immunodeficiency, allergies, autoinflammation, and platelet abnormalities. Currently, indications on the management of this novel disease and information on its outcome are lacking. We report the first case series of 7 children with a homozygous mutation in ARPC1B gene who underwent allogeneic-HSCT (allo-HSCT). All patients presented an early clinical onset, characterized by recurrent infections, failure to thrive and gastrointestinal bleeding episodes complicated with neonatal hemorrhagic enteritis in 3 cases, and macrophage activating syndrome in 2...

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...

OBJECTIVE: To describe the prevalence of HIV viral suppression and assess the factors associated with HIV viral suppression among persons receiving antiretroviral therapy (ART) in Malawi in 2021. METHODS: Implementation study using routinely collected patient-level HIV RNA-PCR test result data extracted from the national Laboratory Management Information System (LIMS) database managed by the Department of HIV/AIDS in 2021. We calculated frequencies, proportions and odds ratios (OR) of HIV viral suppression with their associated 95% confidence intervals (95%CIs)...

BACKGROUND: Increasing evidence from adult cohorts suggests an important role of HIV-1 pretreatment drug resistance (PDR) in ART failure, in spite of treatment being fully active according to baseline genotyping tests. Whether this is also true for children is unknown. METHODS: Virological and immunological parameters were longitudinally assessed in a group of 39 HIV-1 vertically infected children starting first-line lopinavir/ritonavir-based ART at a median of 5...

OBJECTIVE: To assess recent trends in the monitoring of antiretroviral therapy (ART) and detection of ART failure in adult and pediatric HIV clinics. METHODS: We used data collected from 21 adult and 17 pediatric sites (across 13 and 6 countries/territories, respectively) in the International Epidemiology Databases to Evaluate AIDS - Asia-Pacific cohort. ART failure was defined as viral, immune, or clinical consistent with WHO guidelines. RESULTS: A total of 8567 adults and 6149 children contributed data...

BACKGROUND: Children and adolescents living with HIV (CALHIV) face unique challenges, including poorer treatment outcomes, risk for drug resistance mutations (HIVDRM), and limited drug formulations. We estimated viral suppression (VS) prevalence, and evaluated predictors of VS and HIVDRMs in Kenya. METHODS: From 2018-2020, CALHIV 1-19 years on ART for >6 months were enrolled in this cross-sectional study. Participants underwent viral load (VL) testing; those with VL ≥1000 copies/mL had HIVDRM testing...

INTRODUCTION: Efavirenz (EFV) is commonly used for first-line antiretroviral therapy in children and adolescents with HIV, but is associated with neuropsychiatric and metabolic side effects. Rilpivirine (RPV) is better tolerated, and switching from EFV to RPV in virologically suppressed adults has been safe and efficacious, but data in adolescents are limited. Our primary objective was to describe the 48-week immunologic and virologic outcomes in virologically suppressed adolescents switching from EFV- to RPV-based antiretroviral therapy...

INTRODUCTION: Globally, HIV-related adolescent deaths have increased about 50%, especially for those who are vertically infected. This could be driven by archived drug resistance mutations (DRMs) as children grow up, which might jeopardize antiretroviral therapy (ART). Our objective was to compare HIV-1 genotypic variation between plasma RNA and proviral DNA of vertically infected adolescents (aged 10-19 years) failing ART. METHODS: A comparative study was conducted in 2019 among 296 adolescents with perinatal HIV infection (ALPHI) failing ART in health facilities of the Centre Region of Cameroon...

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...

BACKGROUND: Loss to follow-up (LFTU) among HIV patients remains a major obstacle to achieving treatment goals with the risk of failure to achieve viral suppression and thereby increased HIV transmission. Although use of clinical decision support systems (CDSS) has been shown to improve adherence to HIV clinical guidance, to our knowledge, this is among the first studies conducted to show its effect on LTFU in low-resource settings. METHODS: We analyzed data from a cluster randomized controlled trial in adults and children (aged ≥ 18 months) who were receiving antiretroviral therapy at 20 HIV clinics in western Kenya between Sept 1, 2012 and Jan 31, 2014...

BACKGROUND: Children living with HIV and taking antiretroviral therapy (ART) are a priority group for routine viral load (VL) monitoring. As per Lesotho guidelines, a VL ≥1000 copies/mL ("unsuppressed") should trigger adherence counseling and a follow-up VL; 2 consecutive unsuppressed VLs ("virologic failure") qualify for switching to second-line ART, with some exceptions. Here, we describe the pediatric VL cascade in Lesotho. METHODS: In a prospective open cohort study comprising routine VL results from 22 clinics in Lesotho, we assessed outcomes along the VL cascade for children who had at least 1 VL test from January 2016 through June 2020...

HIV-specific CD8+ T-cells play a central role in immune control of adult HIV, but their contribution in paediatric infection is less well-characterised. Previously, we identified a group of ART-naïve children with persistently undetectable plasma viraemia, termed 'elite controllers', and a second group who achieved aviraemia only transiently. To investigate the mechanisms of failure to maintain aviraemia, we characterized in three transient aviraemics (TAs), each of whom expressed the disease-protective HLA-B*81:01, longitudinal HIV-specific T-cell activity and viral sequences...

BACKGROUND: Long-term impact of drug resistance in perinatally infected children and adolescents living with HIV (CALWH) is poorly understood. We determined drug resistance and examined its long-term impact on failure and mortality in Kenyan CALWH failing first-line non-nucleoside reverse transcriptase inhibitor-based antiretroviral therapy (ART). SETTING: Academic Model Providing Access to Healthcare, western Kenya. METHODS: Participants were enrolled in 2010-2013 (timepoint 1) and a subsample re-enrolled after 4-7 years (timepoint 2)...

While the progress towards reaching the UNAIDS 95-95-95 targets in South African adults seems promising, the progress in the paediatric population is lagging far behind; only 79% percent of children living with HIV know their status. Of these, only 47% are on treatment, and a mere 34% of those are virally suppressed. Thus, virological suppression has been attained in only 13% of children living with HIV in South Africa. Multiple factors contribute to the high treatment failure rate, one of them being a lack of paediatric-friendly antiretroviral treatment (ART) formulations...

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...

Background: Health care workers (HWs) support HIV positive children and adolescents with detectable HIV viral loads on the intensive adherence counselling (IAC) program to achieve viral suppression through individual adherence counselling. Low re-suppression rates of 23% showed low program effectiveness in fifteen public health facilities. Objectives: We set out to determine the knowledge and perceptions of HWs that support this program to improve its effectiveness...

INTRODUCTION: A family-centered care model (FCCM) providing family-based HIV services, rather than separate adult/pediatric services, has been proposed to increase pediatric retention and treatment adherence. MATERIALS AND METHODS: Eight health-care facilities in the Hhohho region of Eswatini were randomized to implement FCCM (n = 4) or continue standard-of-care (SOC) separate adult/pediatric clinics (n = 4). HIV-positive children and caregivers were enrolled; caregiver interview and child/caregiver chart abstraction were done at enrollment and every three months; pediatric viral load was evaluated at enrollment and every six months through 12 months...

The 2021 Conference on Retroviruses and Opportunistic Infections included advances in therapy for HIV as well as for SARS-CoV-2. Data presented on COVID-19 therapies included trials showcasing the use of monoclonal antibodies for prevention and treatment of COVID-19. Promising new data were presented on lenacapavir, an investigational HIV capsid inhibitor given as a subcutaneous injection every 6 months. Although encouraging data from settings across the globe reported achievement of 90-90-90 HIV care cascade targets, disparities exist in care engagement and viral suppression, particularly for people of color and young people with HIV...
