Abstract
OBJECTIVE Kenya ART guidelines recommend three sessions of enhanced adherence counselling (EAC) following detectable viral load. The objective of this study was to assess completion of EAC sessions and factors associated with viral re-suppression amongst adolescents and young persons (AYPs) with persistent viremia in Western Kenya. METHODS A retrospective analysis of routinely collected data abstracted from viral load registers was done. AYP with persistent viremia (consecutive viral load ≥1000 copies/ml) between October 2017 to September 2019 were followed for 12 months; those with more than one follow-up viral load results were analyzed. EAC was satisfactory if at least three sessions attended, barriers identified and addressed. Morisky scores 0 and at least 1 indicated optimal and sub-optimal adherence, respectively. Logistic regression models were used to assess predictors of viral load suppression (VLS). RESULTS Of 124 AYPs with persistent viremia, 118 (95.2%) had documented follow-up viral load results and 119 (96%) completed three EAC sessions. Overall, 55 (47%) clients re-suppressed during the study period. AYPs who had satisfactory EAC sessions had higher odds of achieving VLS [odds ratio (OR) = 3.7, 95% confidence interval (CI): 1.6-8.1]. Similarly, AYPs with an optimal adherence had eight times (OR = 8.1, 95% CI: 3.5-18.5) higher odds of achieving VLS, and those who were suppressed at 6 months post-ART initiation had higher odds of achieving VLS at 12-months (OR = 2.5, 95% CI: 1.1-5.8). CONCLUSION Satisfactory EAC sessions and optimal ART adherence was strongly associated with viral re-suppression among AYPs with persistent viremia. Continued support to EAC intervention is critical to improve treatment outcome among AYP living with HIV.

Abstract
Single tablet regimens (STRs) have simplified antiretroviral therapy (ART) over the years in the adult human immunodeficiency virus (HIV) population. However, there is still a prevalent need to simplify regimens in children and adolescents living with HIV. Finding the optimal regimen requires a multi-factorial approach due to their complex pharmacokinetic profiles throughout childhood and the challenges and limitations of medication non-adherence in the pediatric population. These challenges include pill size, available formulations, palatability, and caregiver health literacy, which can all affect the proper administration of medications. The complexity of this population implies the importance of customizing everyone's antiretroviral regimen so that the patient and family can successfully adhere to the therapy. The current recommendations for ART in the adult and pediatric populations are similar, yet the use of STRs are limited. The goal of this review was to assess current data on available STRs and determine their utility as ART in the pediatric population.

Abstract
In 2018, Rio Grande do Sul (RS) had some of the highest HIV/AIDS rates in Brazil, and we did not find any studies about the HIV care and treatment cascade (HCTC) related to this state. We aimed to estimate the indicators of HCTC of RS, Brazil, and associated factors. A cross-sectional study with all people living with HIV (PLWH) in RS between 1 January 2014 and 31 December 2017 was conducted using a national database which registers all HIV notifications, CD4 and viral load laboratory data and antiretroviral therapy (ART) usage in the public health system. We considered sex, age, education, race, year of HIV diagnosis, and health region as predictor factors, and defined linkage to care, retention to care, being on ART, and having undetectable viral load as the HCTC indicators. Descriptive analysis and multivariable logistic regression were performed using Stata 15.2. A total of 116,121 PLWH were diagnosed, 79,959 were linked to care, 72,117 retained in care, 69,219 on ART, and 54,857 had undetectable viral load from 2014 to 2017. We observed greatest attrition for younger age, non-white, and lower education in all HCTC indicators. Women are more likely to have undetectable viral load (OR = 1.04, 95% CI: 1.01-1.07), even though they are less likely to be retained to care (OR = 0.92; 95% CI: 0.89-0.96) and on ART (OR = 0.82; 95% CI: 0.78-0.86). Although all HCTC indicators have increased over the period and the "test and treat" policy indicates improvements in ART and in undetectable viral load outcomes, evidence suggests specific attrition and disparities such as those related to HIV healthcare facilities should be addressed. These findings may be used by researchers, health professionals, and policymakers in order to investigate and implement interventions to better engage PLWH across the HCTC.

Abstract
Human Immunodeficiency Virus (HIV) causes a chronic illness requiring lifelong medical care to prevent opportunistic infections and death. It is important to identify medical neglect in children that are perinatally exposed to or living with human immunodeficiency virus and to take steps to prevent it. Diagnosis of medical neglect must be considered in the context of the caregivers' understanding of the risks of harm, and the logistical, cultural and social factors that may influence their actions or non-actions. When medical neglect as failure of treatment or prevention of infection is suspected, medical providers should work collaboratively with caregivers to assess and address barriers to adherence and to provide resources and support. Medical neglect may be diagnosed if repeated preventive efforts fail.

Abstract
Although refill adherence measures (RAMs) are widely reviewed on their use among adult patients, existing reviews on adherence among children have only focused on self-report measures and electronic monitoring. Hence, this systematic review aims to examine the use of RAMs and their association with economic, clinical, and humanistic outcomes (ECHO) among pediatric patients. A literature search was conducted in Pubmed, Embase, CINAHL, and PsycINFO. Studies published in English involving subjects aged ≤18 years were included if RAMs were analyzed with ECHO. Of the 35 included studies, the majority (n = 33) were conducted in high-income countries. Asthma was the most common condition (n = 9) studied. Overall, 60.6% of 33 clinical outcomes reported among 22 studies was positive (improved clinical outcomes with improved adherence), while 21.9% of 32 economic outcomes reported among 16 studies was positive (reduced healthcare utilization or cost outcomes with improved adherence). Only four studies evaluated the relationship of adherence with 11 humanistic outcomes, where the majority (72.7%) were considered unclear. RAMs are associated with ECHO and can be considered for use in the pediatric population. Future studies could explore the use of RAMs in low-income countries, and the association of RAMs with quality of life.

Abstract
Background Despite the benefits of Antiretroviral Therapy (ART), there is a growing concern of treatment failure. This study aimed to assess viral non suppression rate and factors associated with HIV viral non suppression among adolescents and adults on ART in Northern Ethiopia. Methods A retrospective cross sectional study was done on 19,525 study subjects. All the data in the database of Tigray Health Research Institute was exported to Microsoft excel 2010 and then data verification and filtration were done before exporting to STATA 14.0 for analysis. Generalized Estimating Equation (GEE) logistic regression was used for statistical modeling of viral non suppression. Results A total of 5153 (26.39%; 95%CI (25.77%, 27.02)) patients had no viral suppression despite being on ART. Being male (AOR = 1.27, 95% CI: 1.18, 1.37), 15–19 years of age (AOR = 4.86, 95%CI: 3.86, 6.12), patients from primary hospital (AOR = 1.26, 95%CI: 1.05, 1.52), WHO staging II (AOR = 1.31, 95%CI: 1.10, 1.54), poor ART adherence level (AOR = 2.56, 95%CI: 1.97, 3.33), fair ART adherence level (AOR = 1.61, 95%CI: 1.36, 1.90), baseline CD-4 count of < 200 cells/micro liter (AOR = 1.33, 95%CI: 1.14, 1.54), recent CD-4 count of < 200 cells/micro liter (AOR = 3.78, 95%CI: 3.34, 4.27), regimen types: 1c (AZT-3TC-NVP) (AOR = 1.32, 95%CI: 1.22, 1.44), 2 h (TDF-3TC-ATV/R) (AOR = 1.79, 95%CI: 1.27, 2.52) and declined immunological responses after ART initiation (AOR = 1.45, 95%CI: 1.30, 1.61) were significantly associated with viral non-suppression. Conclusions The virological non suppression was high which makes it less likely to achieve the third 90 UNAIDS target. Being male, patients with WHO staging II and poor ART adherence level were significantly associated with viral non suppression. Therefore, intensive adherence support and counseling should be provided. It is also a high time to determine the antiretroviral drugs resistance pattern given the fact that a large number of patients had virological non suppression.

Abstract
Background An estimated 50% of adolescents and young adults (AYA) living with HIV are failing to adhere to prescribed antiretroviral treatment (ART). Digital games are effective in chronic disease management; however, research on gaming to improve ART adherence among AYA is limited. Objective We assessed the feasibility and acceptability of video gaming to improve AYA ART adherence. Methods Focus group discussions and surveys were administered to health care providers and AYA aged 13 to 24 years living with HIV at a pediatric HIV program in Washington, DC. During focus group discussions, AYA viewed demonstrations of 3 game prototypes linked to portable Wisepill medication dispensers. Content analysis strategies and thematic coding were used to identify adherence themes and gaming acceptance and feasibility. Likert scale and descriptive statistics were used to summarize response frequencies. Results Providers (n=10) identified common adherence barriers and strategies, including use of gaming analogies to improve AYA ART adherence. Providers supported exploration of digital gaming as an adherence intervention. In 6 focus group discussions, 12 AYA participants identified disclosure of HIV status and irregular daily schedules as major barriers to ART and use of alarms and pillboxes as reminders. Most AYA were very or somewhat likely to use the demonstrated game prototypes to help with ART adherence and desired challenging, individually tailored, user-friendly games with in-game incentives. Game prototypes were modified accordingly. Conclusions AYA and their providers supported the use of digital games for ART adherence support. Individualization and in-game incentives were preferable and informed the design of an interactive technology-based adherence intervention among AYA living with HIV.

A Mobile Gaming Intervention to Increase Adherence to Antiretroviral Treatment for Youth Living With HIV: Development Guided by the Information, Motivation, and Behavioral Skills Model. JMIR Mhealth Uhealth 2018; 6:e96. [PMID: 29685863 PMCID: PMC5993532 DOI: 10.2196/mhealth.8155] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2017] [Revised: 10/23/2017] [Accepted: 11/28/2017] [Indexed: 11/13/2022] Open
Abstract
Background Highly active combination antiretroviral treatment has been shown to markedly improve the health of HIV-infected adolescents and young adults. Adherence to antiretroviral treatment leads to decreased morbidity and mortality and decreases the number of hospitalizations. However, these clinical achievements can only occur when young persons with HIV are adherent to care. Unfortunately, adolescents and young adults have poorer rates of adherence to antiretroviral medications and poorer rates of retention in care than older adults. Novel and engaging digital approaches are needed to help adolescents and young adults living with HIV be adherent to treatment. Objective The aim of this study was to develop an immersive, action-oriented iPhone gaming intervention to improve adherence to antiretroviral medication and treatment. Methods Game development was guided by social learning theory, taking into consideration the perspectives of adolescents and young adults living with HIV. A total of 20 adolescents and young adults were recruited from an HIV care clinic in Rhode Island, and they participated in qualitative interviews guided by the information-motivation-behavioral skills model of behavior change. The mean age of participants was 22 years, 60% (12/20) of the participants identified as male, and 60% (12/20) of the sample reported missing a dose of antiretroviral medication in the previous week. Acceptability of the game was assessed with client service questionnaire and session evaluation form. Results A number of themes emerged that informed game development. Adolescents and young adults living with HIV desired informational game content that included new and comprehensive details about HIV, details about HIV as it relates to doctors’ visits, and general health information. Motivational themes that emerged were the desire for enhancement of future orientation; reinforcement of positive influences from partners, parents, and friends; collaboration with health care providers; decreasing stigma; and increasing personal relevance of HIV care. Behavioral skills themes centered on self-efficacy and strategies for medical adherence and self-care. On the client service questionnaire, 10 out of the 11 participants indicated they were “satisfied with the game activities,” and 9 out of 11 “would recommend it to a friend.” On the session evaluation form, 9 out of 11 agreed that they “learned a lot from the game.” Conclusions We utilized youth feedback, social learning theory (information-motivation-behavioral skills), and agile software development to create a multilevel, immersive, action-oriented iPhone gaming intervention to measure and improve treatment adherence for adolescents and young adults living with HIV. There is a dearth of gaming interventions for this population, and this study is a significant step in working toward the development and testing of an iPhone gaming app intervention to promote adherence to antiretroviral treatment.

Factors Associated with Virological Non-suppression among HIV-Positive Patients on Antiretroviral Therapy in Uganda, August 2014-July 2015. BMC Infect Dis 2017; 17:326. [PMID: 28468608 PMCID: PMC5415758 DOI: 10.1186/s12879-017-2428-3] [Citation(s) in RCA: 137] [Impact Index Per Article: 19.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2016] [Accepted: 04/28/2017] [Indexed: 01/12/2023] Open
Abstract
Background Despite the growing number of people on antiretroviral therapy (ART), there is limited information about virological non-suppression and its determinants among HIV-positive (HIV+) individuals enrolled in HIV care in many resource-limited settings. We estimated the proportion of virologically non-suppressed patients, and identified the factors associated with virological non-suppression. Methods We conducted a descriptive cross-sectional study using routinely collected program data from viral load (VL) samples collected across the country for testing at the Central Public Health Laboratories (CPHL) in Uganda. Data were generated between August 2014 and July 2015. We extracted data on socio-demographic, clinical and VL testing results. We defined virological non-suppression as having ≥1000 copies of viral RNA/ml of blood for plasma or ≥5000 copies of viral RNA/ml of blood for dry blood spots. We used logistic regression to identify factors associated with virological non-suppression. Results The study was composed of 100,678 patients; of these, 94,766(94%) were for routine monitoring, 3492(4%) were suspected treatment failures while 1436(1%) were repeat testers after suspected failure. The overall proportion of non-suppression was 11%. Patients on routine monitoring registered the lowest (10%) proportion of non-suppressed patients. Virological non-suppression was higher among suspected treatment failures (29%) and repeat testers after suspected failure (50%). Repeat testers after suspected failure were six times more likely to have virological non-suppression (ORadj = 6.3, 95%CI = 5.5–7.2) when compared with suspected treatment failures (ORadj = 3.3, 95%CI = 3.0–3.6). The odds of virological non-suppression decreased with increasing age, with children aged 0–4 years (ORadj = 5.3, 95%CI = 4.6–6.1) and young adolescents (ORadj = 4.1, 95%CI = 3.7–4.6) registering the highest odds. Poor adherence (ORadj = 3.4, 95%CI = 2.9–3.9) and having active TB (ORadj = 1.9, 95%CI = 1.6–2.4) increased the odds of virological non-suppression. However, being on second/third line regimens (ORadj = 0.86, 95%CI = 0.78–0.95) protected patients against virological non-suppression. Conclusion Young age, poor adherence and having active TB increased the odds of virological non-suppression while second/third line ART regimens were protective against non-suppression. We recommend close follow up and intensified targeted adherence support for repeat testers after suspected failure, children and adolescents.

Abstract
Objective: Evaluate the impact of fixed-dose combination (FDC) containing emtricitabine (FTC), tenofovir (TDF), and efavirenz (EFV) versus a free-dose combination (FRC) of the same three drugs on clinical outcomes, adherence and quality of life in Malaysian outpatients with HIV. Methods: HIV patients (n=120) on highly active antiretroviral therapy (HAART) in the infectious disease clinic of Hospital Sungai Buloh were randomized to either FDC (n=60) or FRC (n=60). Morisky scores, health-related quality of life scores and clinical outcomes such as CD4 count and viral load were assessed in both groups at baseline and six months. Result: Patients on FDC (108 SD=1.1) had a significantly higher CD4 count increase compared to the FRC group (746.1 SD=36.3 vs 799.8 SD=33.8) (p <0.001). The viral load profile was unchanged and remained undetectable in both groups. The quality of life EQ-5D scores showed a positive correlation with CD4 counts in the FDC group (ρ=0.301, p=0.019) at six months. On the other hand, quality of life EQ-VAS scores was significantly associated with medication adherence in the FDC group at six months (ρ=0.749, p=0.05). However, no significant changes or associations were observed in the FRC group. Conclusion: Management of HAART using an FDC demonstrated a positive clinical outcome, adherence and quality of life within six months in local HIV patients.

Abstract
BACKGROUND The effectiveness of highly active antiretroviral therapy (HAART) in children has not been well studied specially in developing countries where the burden of HIV is high. This study was aimed to assess the immunologic response of HIV-infected children to HAART at Pediatric ART Clinic Gondar University Hospital. METHODS Institution based cross-sectional study was conducted at the Pediatric ART Clinic Gondar University Hospital from March 01-April 30, 2014. The study included 283 HIV-infected children who were on HAART for 6 months and above. Medical records of HIV-infected children were reviewed using pre-tested questionnaire. CD4 count/percent was collected every 6 months retrospectively. For all statistical significance tests, the cut-off value was p<0.05. Poison Regression was used for further analysis. RESULTS The mean age of children was 6.9 years with a standard deviation of 3.4 years. The median CD4 count/percent was 232/13%, 450/21%, 540/25% and 608/27% at the time of initiation, 6, 12 and 18 months of ART, respectively. HAART initiated at higher CD4 count, good adherence and HIV status disclosure were found to have positive effects for immunological response. CONCLUSION The study revealed that there was good Immunological response to ART, and that the maximum response was in the 1(st) 6 months of ART. Low CD4 count at initiation, undisclosed HIV status and lack of good adherence were found to cause low immunological response to HAART.

Abstract
BACKGROUND Successful treatment of HIV-positive children requires a high level of adherence (at least 95%) to highly active antiretroviral therapy. Adherence is influenced by factors related to the child and caregivers. OBJECTIVES To evaluate children and caregivers characteristics associated to children's adherence. METHODS Cross-sectional study, from September 2013 to June 2015, comprising a sample of caregivers of perinatally HIV-infected children, in the age group of 1-12 years, under antiretroviral therapy for at least 6 months and on follow-up in two AIDS reference centers in Salvador, Bahia. Caregiver self-reports were the sole source of 4 days adherence and sociodemographic information. Study participants who reported an intake >95% of prescribed medication were considered adherents. A variable, ("Composed Adherence"), was created to better evaluate adherence. RESULTS We included 77 children and their caregivers. 88.3% of the caregivers were female, the median age was 38.0 years (IQR 33.5-47.5), 48.1% were white or mixed, 72.7% lived in Salvador and 53.2% had no fixed income. The 4 days child's adherence was associated only to caregivers that received less than a minimum salary (p<0.05), 70.1% of the caregivers had less than four years of formal education, 81.8% were children's relative and 53.2% of the caregivers were HIV positive. The caregiver's pharmacy refill, long-term adherence and 4 days adherence, were significantly associated with composed adherence (p<0.05). Child's long-term adherence was strongly associated to the 4 days child's adherence referred by caregiver (p<0.001). CONCLUSIONS Our results suggest the need of improvement in HIV-infected children adherence, through reinforcement of the caregivers own adherence.

Abstract
Over 3.2 million children worldwide are infected with HIV, but only 24% of these children receive antiretroviral therapy (ART). ART adherence among children is a crucial part of managing human-immunodeficiency virus (HIV) infection and extending the life and health of infected children. Important causes of poor adherence are formulation- and regimen-specific properties, including poor palatability, large pill burden, short dosing intervals, and the complex storage and transportation of drugs. This review aims to summarize the various regimen- and formulation-based barriers to ART adherence among children to support the need for new and innovative pediatric formulations for antiretroviral therapy (ART). Detailing the arguments both for and against investing in the development of pediatric HIV medications, as well as highlighting recent advances in pediatric ART formulation research, provides a synopsis of the current data related to pediatric ART formulations and adherence.

Abstract
Adherence to ART, fundamental to treatment success, has been poorly studied in India. Caregivers of children attending HIV clinics in southern India were interviewed using structured questionnaires. Adherence was assessed using a visual analogue scale representing past-month adherence and treatment interruptions >48 h during the past 3 months. Clinical features, correlates of adherence and HIV-1 viral-load were documented. Based on caregiver reports, 90.9 % of the children were optimally adherent. In multivariable analysis, experiencing ART-related adverse effects was significantly associated with suboptimal adherence (p = 0.01). The proportion of children who experienced virological failure was 16.5 %. Virological failure was not linked to suboptimal adherence. Factors influencing virological failure included running out of medications (p = 0.002) and the child refusing to take medications (p = 0.01). Inclusion of drugs with better safety profiles and improved access to care could further enhance outcomes.

Abstract
Background Viral load is still the marker of choice for monitoring adherence to combined antiretroviral therapy (cART) and confirming the success of HIV treatment. Unfortunately it is difficult to access in many resource-poor settings. We aimed to measure the performance of caregiver reporting adherence for detecting virological failure in routine practice during the first 2 years after cART initiation in infants. Methods PEDIACAM is an ongoing prospective cohort study including HIV1-infected infants diagnosed before 7 months of age between November 2007 and October 2011 in Cameroon. Adherence was assessed using a questionnaire administered every 3 months from cART initiation; the HIV-RNA viral load was determined at the same visits. Virological failure was defined as having a viral load ≥ 1000 cp/mL at 3 and 12 months after cART initiation or having a viral load ≥ 400 cp/mL at 24 months after cART initiation. The performance of each current missed and cumulative missed dose defined according to adherence as reported by caregiver was assessed using the viral load as the gold standard. Results cART was initiated at a median age of 4 months (IQR: 3–6) in the 167 infants included. The cumulative missed dose showed the best overall performance for detecting virological failure after 12 months of cART (AUC test, p = 0.005, LR + =4.4 and LR− = 0.4). Whatever the adherence reporting criterion, the negative predictive value was high (NPV ≥ 75 %) 12 and 24 months after cART initiation, whereas the positive predictive value was low (PPV ≤ 50 %). Conclusions The adherence questionnaire administered by the health care provider to the infants’ caregivers is not reliable for detecting virological failure in routine practice: its positive predictive value is low. However, the cumulative missed dose measurement may be a reliable predictor of virological success, particularly after 12 months of cART, given its high negative predictive value.

Abstract
We evaluated the evolution over time of once-daily antiretroviral therapy in HIV-infected children and its relationship with adherence. An increase on the prevalence of once-daily antiretroviral therapy was observed over time (from 0.9% in 2002 to 44.2% in 2011). There was no difference in adherence regarding once-daily or BID regimens in 2011. Adherence was related to age and pill burden.

Abstract
Background: Assessment of longitudinal adherence patterns on virologic and immunologic responses to HAART in perinatally acquired HIV patients has not been studied. Methods: Perinatally infected pediatric HIV patients with adherence documented at least twice and corresponding viral load and T-cell (%) data measured during 2008-2009 were studied. Multiple adherence measures were utilized to identify patients with persistent adherence, nonadherence, or alteration of adherence. Virologic and immunologic outcomes were assessed. Results: Persistent adherence, nonadherence, and alteration of adherence to HAART were recorded in 41.9%, 8.1%, and 50.0% of 62 studied patients. Persistent adherence was associated with higher likelihood for persistent virologic suppression and lower risk for persistent virologic failure. Conclusion: Alteration of adherence to HAART is a significant predictor of persistent virologic failure and high viremia in perinatally infected HIV patients. Implementation of longitudinal adherence assessments may target patients with nonsustained adherence patterns and help decrease the risk for virologic failure and disease progression.

Abstract
The global impact of sexually transmitted infections (STIs) is significant. The sexual transmission of viruses such as herpes simplex virus type-2 (HSV-2) and the human immunodeficiency virus type-1 (HIV-1), has been especially difficult to control. To date, no effective vaccines have been developed to prevent the transmission of these STIs. Although antiretroviral drugs have been remarkably successful in treating the symptoms associated with these viral infections, the feasibility of their widespread use for prevention purposes may be more limited. Microbicides might provide an attractive alternative option to reduce their spread. In particular, topically applied small inhibitory RNAs (siRNAs) have been shown to not only block transmission of viral STIs to mucosal tissues both in vitro and in vivo, but also confer durable knockdown of target gene expression, thereby circumventing the need to apply a microbicide around the time of sexual encounter, when compliance is mostly difficult. Despite numerous clinical trials currently testing the efficacy of siRNA-based therapeutics, they have yet to be approved for use in the treatment of viral STIs. While several obstacles to their successful implementation in the clinic still exist, promising preclinical studies suggest that siRNAs are a viable modality for the future prevention and treatment of HSV and HIV.

Abstract
We assessed programmatic gaps that prevent the optimal treatment of pediatric HIV infection despite free antiretroviral care in Kenya. Of 626 HIV-infected Kenyan children, the median age was five years, 54% were male and the mortality rate was 3.2 per 100 person-years. A total of 380 (61%) children initiated antiretroviral therapy (ART) during the study period. Among the 246 children who never started ART, 129 (52%) met the criteria for ART initiation. Immunologic failure occurred in 20% of children who received ART for >24 weeks. In multivariate analysis, immunological failure was associated with having nonimmediate relative or unrelated caregivers accompanying the child to clinic (AOR = 69.16, p = 0.008). Having ≥ 3 types of accompanying caregivers was also associated with virologic failure in multivariate analysis (AOR = 3.84, p = 0.03). The lost to follow-up rate was 8.7/100 persons-years for the entire cohort, and significantly higher (17.7/100 persons-years) among children not on ART (p < 0.001). Among children who do initiate ART, those with the best treatment outcomes were those who had a limited number of close relatives as caregivers and good adherence to ART. Focus on early ART initiation and education of the right caregiver will likely improve retention and quality of pediatric HIV care in Kenya.

Abstract
INTRODUCTION The efficiency of antiretroviral therapy (ART) depends on a near-perfect level of patient's adherence. Adherence in children poses peculiar challenges. The aim of the study was to determine the adherence level and factors influencing adherence among HIV-infected children and adolescents in University of Port Harcourt Teaching Hospital, Nigeria. METHODS A cross-sectional survey of HIV-infected children and adolescents on ART using self-report by the caregiver/child in the past one month. RESULTS A total of 213 caregivers and their children were interviewed. A hundred and sixty-two (76.1%) had adherence rates ≥95%. Only 126 (59.2%) were completely (100%) adherent. The commonest caregiver-related factors for missing doses were forgetfulness 48(55.2%), travelled 22(25.3%) and drugs finished 16(18.4%), while the child-related factors were refused drugs 10(11.5%), slept 8(9.2%), and vomited 8(9.2%). Sixty-eight (31.9%) caregivers reported missing clinic visit and reasons given were travelled 18(26.5%), caregiver ill 12(17.6%) and family problems 9(13.2%). Predictors of poor adherence include mother as the primary caregiver (OR 3.32; 95%CI, 1.33-8.67), younger than 5 years (OR 2.62; 95%CI, 1.30-5.31) and presence of a co-morbidity (OR 3.97; 95%CI, 1.92-8.33). Having a medication reminder strategy (OR 6.34; 95%CI, 3.04-13.31), regular clinic visits (OR 8.55; 95%CI 4.01-18.45) and status disclosure (p = 0.008) predicted a better adherence. The caregiver's age (p= 0.11), education (p = 0.86), socioeconomic status (p = 0.89), gender of the child (p = 0.84), type of ART (p = 0.2) and duration of ART (1.0) did not significantly affect adherence. CONCLUSION Adherence is still suboptimal. Since barriers to Paediatric ART adherence are largely caregiver-dependent, identifying and addressing these barriers in each caregiver-child pair will improve adherence and patient outcome.

Abstract
BACKGROUND Non-adherence reduces the effectiveness of antiretroviral therapy in children attending the paediatric HIV/AIDS clinic at Mulago Hospital, Kampala. AIM To determine the levels of adherence to HAART and identify factors associated with non-adherence. METHODS A cross-sectional study of 170 children aged 2-18 years. Adherence to HAART was defined as taking > or =95% of prescribed medication. It was determined using three measures: a 3-day self-report by the caregivers, clinic-based pill counts at enrolment and home-based unannounced pill counts 2-3 weeks later. RESULTS The 3-day self-reported > or =95% adherence was 89.4% (n=170). Using clinic-based pill counts, 94.1% (n=170) had > or =95% adherence to treatment compared with only 72% (n=164) by unannounced pill counts. When the primary caregiver was the only one who knew the child's serostatus, he/she was three times more likely to be non-adherent (p=0.02, OR 3.34, 95% CI 1.14-9.82). Those who had been hospitalised twice or more before starting HAART were more likely to have > or =95% adherence (p=0.02, OR 0.44, 95% CI 0.20-0.92). CONCLUSION The majority of children had good adherence levels when estimated by unannounced pill counts. Disclosing the child's HIV serostatus only to the primary caregiver and having been hospitalised only once or not at all were associated with poor adherence.

Abstract
OBJECTIVE The objective of this study was to develop in children an HIV dynamic model able to predict simultaneously the viral load and CD4 lymphocyte evolutions, and to take into account, through a composite inhibition score, the relative contribution of each drug of the combination efavirenz-didanosine-lamivudine and use this score as a predictor of treatment failure in a multidrug therapy. DESIGN Open phase II trial (BURKINAME - ANRS 12103) registered in the ClinicalTrials.gov database (http://clinicaltrials.gov) with the no. NCT00122538. METHODS Forty-nine children aged from 2.5 to 15 years were administered once-daily dose of lamivudine, didanosine and efavirenz. The three drugs effect was then characterized by a composite inhibition score combining the effect of each drug, according to their site and mechanism of action and their relative contribution. RESULTS Efavirenz was the most potent antiretroviral and was responsible for 65% of the total effect, and then didanosine for 23% and lamivudine was the less potent with 12% of the total observed effect. An EC90 for efavirenz was determined (3.3 mg/l). AUC90 was estimated for lamivudine and didanosine: 8.4 and 1.5 mg h/l, respectively. The composite inhibition score was the best predictor of virologic failure compared with the concentrations of each drug taken independently [hazard ratio (HR) 0.6 per 10% increase, 95% confidence interval (CI) 0.41-0.88]. CONCLUSION The relative contributions of three combined drugs were assessed on plasma viral load and CD4 lymphocyte count kinetics in HIV-1-infected children. Pharmacokinetics targets have been suggested for lamivudine and didanosine. A composite inhibition score has been determined to be a high predictor of treatment failure in a multidrug therapy.

Abstract
BACKGROUND There is limited information on antiretroviral (ARV) regimens and outcomes in perinatally HIV (PHIV)-infected youth. Substantial drug resistance after long-term ARV use and nonadherence hinder efforts to design suppressive regimens for PHIV-infected youth. This study compares clinical outcomes by expected activity of the prescribed ARV regimens. METHODS A retrospective cohort study of 13- to 24-year-old PHIV-infected youth on stable ARV regimens for ≥6 months was conducted at a pediatric HIV clinic. ARV regimens were retrospectively categorized as optimal or suboptimal based on accumulated genotypic resistance before study regimen initiation. RESULTS Fifty-two patients with similar baseline characteristics met inclusion criteria (21 optimal and 31 suboptimal regimens). Patients receiving optimal regimens had significantly higher increases in CD4 than those given suboptimal regimens by week 48 of treatment (+62 versus +8 cells/mm, respectively; P = 0.04) and by the end of study period (+93 versus -1 cells/mm, respectively; P = 0.03). There were no significant differences between the groups in decline of viral load, frequency of opportunistic infections or hospitalizations or accumulation of resistance mutations. Overall, 60% of the optimal and 45% of the suboptimal groups had nonadherence during the study regimen (P = 0.3). CONCLUSIONS PHIV-infected youth receiving optimal regimens had greater CD4 improvements but no difference in virologic outcomes compared with those receiving suboptimal regimens. In a patient population with significant nonadherence, providers must weigh the immunologic benefits of initiating an optimal regimen versus the potential risks of further resistance accumulation limiting future treatment options.

Abstract
BACKGROUND Achieving and maintaining high levels of medication adherence are required to achieve the full benefits of antiretroviral therapy (ART), yet suboptimal adherence among children is common in both developed and developing countries. OBJECTIVES To conduct a systematic review of the literature of evaluations of interventions for improving paediatric ART adherence. SEARCH METHODS We created a comprehensive search strategy in order to identify all studies relevant to this topic. In July 2010, we searched the following electronic databases: EMBASE, MEDLINE, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, LILACS, Web of Science, Web of Social Science, NLM Gateway (supplemented by a manual search of the most recent abstracts not included in the Gateway database). We searched abstracts from the International AIDS Conference from 2002 to 2010, the International AIDS Society Conference on Pathogenesis, Treatment and Prevention from 2003 to 2009, and from the Conference on Retroviruses and Opportunistic Infections from 1997 to 2010. We used search strategies determined by the Cochrane Review Group on HIV/AIDS. We also contacted researchers who work in this field and checked reference lists of related systematic reviews and of all included studies. SELECTION CRITERIA Randomised and non-randomised controlled trials of interventions to improve adherence to ART among children and adolescents (age ≤18 years) were included. Studies had to report adherence to ART as an outcome. DATA COLLECTION AND ANALYSIS After one author performed an initial screening to exclude citations that did not meet the inclusion criteria, two authors did a second screening of those citations that likely met the criteria. For all articles that passed the second screening, full articles were pulled in order to make a final determination. Two authors then extracted data and graded methodological quality independently. Differences were resolved through discussion. MAIN RESULTS Four studies met the inclusion criteria. No single intervention was evaluated by more than one trial. Two studies were conducted in low-income countries. Two studies were randomised controlled trials (RCT), and two were non-randomised trials. An RCT of a home-based nursing programme showed a positive effect of the intervention on knowledge and medication refills (p=.002), but no effect on CD4 count and viral load. A second RCT of caregiver medication diaries showed that the intervention group had fewer participants reporting no missed doses compared to the control group (85% vs. 92%, respectively), although this difference was not statistically significant (p=.08). The intervention had no effect on CD4 percentage or viral load. A non-randomised trial of peer support group therapy for adolescents demonstrated no change in self-reported adherence, yet the percentage of participants with suppressed viral load increased from 30% to 80% (p=.06). The second non-randomised trial found that the percentage of children achieving >80% adherence was no different between children on a lopinavir-ritonavir (LPV/r) regimen compared to children on a non-nucleoside reverse transcriptase regimen (p=.781). However, the proportion of children achieving virological suppression was significantly greater for children on the LPV/r regimen than for children on the NNRTI-containing regimen (p=.002). AUTHORS' CONCLUSIONS A home-based nursing intervention has the potential to improve ART adherence, but more evidence is needed. Medication diaries do not appear to have an effect on adherence or disease outcomes. Two interventions, an LPV/r-containing regimen and peer support therapy for adolescents, did not demonstrate improvements in adherence, yet demonstrated greater viral load suppression compared to control groups, suggesting a different mechanism for improved health outcomes. Well-designed evaluations of interventions to improve paediatric adherence to ART are needed.

Abstract
Access to antiretroviral therapy (ART) and routine laboratory monitoring are limited for HIV-1-infected children from sub-Saharan Africa. This trial conducted in Bobo-Dioulasso, Burkina Faso, aimed to describe the biological efficacy, tolerance, and adherence of the combination of didanosine, lamivudine, efavirenz in once-daily administration among eligible HIV-1-infected children. From February 2006 to November 2007, 51 HIV-1-infected children aged from 30 months to 15 years and eligible for ART were enrolled in a phase II open clinical trial with follow-up visits every 3 months. HIV-1 genotype testing was performed in children with plasma viral load (PVL) >1000 copies per milliliter after ART initiation. Children were followed for a median of 13.4 months [interquartile range (IQR) 12.8-14.2]. At enrollment, median CD4 count was 8% (IQR = 4.5-12). PVL was 341,032 (IQR = 127,838-761,539) copies per milliliter. At 12 months, median CD4 increased significantly by +15% (P < 10(-3)), and median PVL decreases significantly by -290,500 copies per milliliter (P < 10(-4)). Hemoglobin and platelets counts increased significantly by +1.05 g/dL (P < 10(-5)) and 108,500 cells per milliliter (P < 10(-3)), respectively. Based on pill count, mean yearly adherence was 97.3%, and 48% of the children had an adherence rate ≥ 95% at the four quarterly visits. Adherence was better for girls than for boys independently of other sociodemographic variables or markers of HIV disease progression. Drug-resistant mutations were found in 11 children (21.6%). This once-daily drug combination is associated with excellent virological efficacy, immune reconstitution, and good adherence. However, the high prevalence of drug resistance mutations is a matter of concern.

Abstract
PURPOSE To assess the impact of perceived palatability of antiretroviral drugs on adherence to therapy of children infected by human immunodeficiency virus and on prescribing patterns by their caring physicians. METHODS DESIGN Two arms--retrospective chart review and a cross-sectional survey. SETTING Tertiary-care pediatric human immunodeficiency virus clinic during a 17-year period. PARTICIPANTS Children with human immunodeficiency virus infection and physicians actively caring for children with human immunodeficiency virus infection in seven provinces in Canada were surveyed regarding their perception of the palatability of 8-liquid and 15 non-liquid antiretroviral medications and its effect on drug selection. MAIN OUTCOME MEASURE Effect of taste preferences of antiretroviral drugs on adherence to treatment by infected children and on drug selection by their caring physicians. RESULTS Forty of 119 children (34%) refused at least once to an antiretroviral medication. In 5%, treatment was discontinued because of poor palatability. Ritonavir was the least palatable drug (50% of children; p = 0.01). Ritonavir use (OR 4.80 [95%CI 1.34-17.20]) and male gender (OR 7.25 [95%CI 2.30-22.90]) were independent predictors of drug discontinuation because of poor taste. Physicians also perceived liquid ritonavir as the least palatable (p = 0.01) and the most likely to be discontinued (p = 0.01). However, they commonly prescribed it as first-line therapy (p = 0.06). CONCLUSIONS A third of children infected with human immunodeficiency virus fail to adhere to their treatment because of poor drug taste. Physicians are aware of that, but this does not prevent them from selecting the least palatable drugs as first-line therapy.

Abstract
Given relatively high levels of adherence to HIV treatment in Africa, we explore factors facilitating children's adherence, despite poverty, social disruption and limited health infrastructure. Using interviews with 25 nurses and 40 guardians in Zimbabwe, we develop our conceptualisation of an ‘adherence competent community’, showing how members of five networks (children, guardians, community members, health workers and NGOs) have taken advantage of the gradual public normalisation of HIV/AIDS and improved drug and service availability to construct new norms of solidarity with HIV and AIDS sufferers, recognition of HIV-infected children's social worth, an ethic of care/assistance and a supporting atmosphere of enablement/empowerment.

Abstract
CONTEXT No formal comparison has been made between the pediatric post-highly active antiretroviral therapy (HAART) outcomes of resource-limited and developed countries. OBJECTIVE To systematically quantify and compare major baseline characteristics and clinical end points after HAART between resource-limited and developed settings. METHODS Published articles and abstracts (International AIDS Society 2009, Conference on Retroviruses and Opportunistic Infections 2010) were examined from inception (first available publication for each search engine) to March 2010. Publications that contained data on post-HAART mortality, weight-for-age z score (WAZ), CD4 count, or viral load (VL) changes in pediatric populations were reviewed. Selected studies met the following criteria: (1) patients were younger than 21 years; (2) HAART was given (≥ 3 antiretroviral medications); and (3) there were >20 patients. Data were extracted for baseline age, CD4 count, VL, WAZ, and mortality, CD4 and virologic suppression over time. Studies were categorized as having been performed in a resource-limited country (RLC) or developed country (DC) on the basis of the United Nations designation. Mean percentage of deaths per cohort and deaths per 100 child-years, baseline CD4 count, VL, WAZ, and age were calculated for RLCs and DCs and compared by using independent samples t tests. RESULTS Forty RLC and 28 DC publications were selected (N = 17 875 RLCs; N = 1835 DC). Mean percentage of deaths per cohort and mean deaths per 100 child-years after HAART were significantly higher in RLCs than DCs (7.6 vs 1.6, P < .001, and 8.0 vs 0.9, P < .001, respectively). Mean baseline CD4% was 12% in RLCs and 23% in DCs (P = .01). Mean baseline VLs were 5.5 vs 4.7 log(10) copies per mL in RLCs versus DCs (P < .001). CONCLUSIONS Baseline CD4% and VL differ markedly between DCs and RLCs, as does mortality after pediatric HAART. Earlier diagnosis and treatment of pediatric HIV in RLCs would be expected to result in better HAART outcomes.

Abstract
BACKGROUND Children with HIV will be on antiretroviral therapy (ART) longer than adults, and therefore the durability of first-line ART and timing of switch to second-line are key questions. We assess the long-term outcome of protease inhibitor and non-nucleoside reverse transcriptase inhibitor (NNRTI) first-line ART and viral load switch criteria in children. METHODS In a randomised open-label factorial trial, we compared effectiveness of two nucleoside reverse transcriptase inhibitors (NRTIs) plus a protease inhibitor versus two NRTIs plus an NNRTI and of switch to second-line ART at a viral load of 1000 copies per mL versus 30,000 copies per mL in previously untreated children infected with HIV from Europe and North and South America. Random assignment was by computer-generated sequentially numbered lists stratified by age, region, and by exposure to perinatal ART. Primary outcome was change in viral load between baseline and 4 years. Analysis was by intention to treat, which we defined as all patients that started treatment. This study is registered with ISRCTN, number ISRCTN73318385. FINDINGS Between Sept 25, 2002, and Sept 7, 2005, 266 children (median age 6.5 years; IQR 2.8-12.9) were randomly assigned treatment regimens: 66 to receive protease inhibitor and switch to second-line at 1000 copies per mL (PI-low), 65 protease inhibitor and switch at 30,000 copies per mL (PI-higher), 68 NNRTI and switch at 1000 copies per mL (NNRTI-low), and 67 NNRTI and switch at 30,000 copies per mL (NNRTI-higher). Median follow-up was 5.0 years (IQR 4.2-6.0) and 188 (71%) children were on first-line ART at trial end. At 4 years, mean reductions in viral load were -3.16 log(10) copies per mL for protease inhibitors versus -3.31 log(10) copies per mL for NNRTIs (difference -0.15 log(10) copies per mL, 95% CI -0.41 to 0.11; p=0.26), and -3.26 log(10) copies per mL for switching at the low versus -3.20 log(10) copies per mL for switching at the higher threshold (difference 0.06 log(10) copies per mL, 95% CI -0.20 to 0.32; p=0.56). Protease inhibitor resistance was uncommon and there was no increase in NRTI resistance in the PI-higher compared with the PI-low group. NNRTI resistance was selected early, and about 10% more children accumulated NRTI mutations in the NNRTI-higher than the NNRTI-low group. Nine children had new CDC stage-C events and 60 had grade 3/4 adverse events; both were balanced across randomised groups. INTERPRETATION Good long-term outcomes were achieved with all treatments strategies. Delayed switching of protease-inhibitor-based ART might be reasonable where future drug options are limited, because the risk of selecting for NRTI and protease-inhibitor resistance is low.

Abstract
Abstract This study explored the role of situational temptation, a component of self-efficacy, in adolescent and young adult (ages 16-24) HIV medication adherence by assessing participants' perceptions of their temptation to miss medications in various situations (e.g., when medication causes physical side effects, when there is fear of disclosure of HIV status). Youth (n = 186; 83% African American) were participants in a multisite clinical trial examining the efficacy of a motivational intervention. Data were collected using computer-assisted personal interviewing. Youth believed the most tempting reasons or situations that might lead them to miss their HIV medications to be symptoms (if the medicine caused you to have other physical symptoms) and sick (if the medicine made you sick to your stomach or made you throw up or if it tasted bad), but these were not significantly associated with nonadherence. This suggests disconnection between youths' expectations of temptation and actual tempting situations associated with nonadherence. Situational temptations associated with nonadherence included lack of social support, needing a break from medications, and not seeing a need for medications. Interventions to improve adherence should consider perceptions of HIV medications, particularly the benefits of taking medications and expectations of physical symptoms. Interventionists and clinicians should consider situations that may tempt youth to miss doses of medication and help youth gain insight into these temptations. Emerging methods, such as Ecological Momentary Assessment (e.g., daily diaries, cell phone text messaging), may be useful in gaining insight into the day-to-day experience of youth living with HIV.

Abstract
The evaluation of HIV treatment adherence is essential to manage the development of resistant mutations, treatment failure, and disease progression in patients with HIV-1 infection; however, none of the commonly used measures of treatment adherence have been found to be accurate. The objective of this study was to evaluate three treatment adherence measures (caregiver reports, pharmacy refill, and appointment maintenance data) in association with viral load suppression in pediatric patients with HIV-1 infection. Although viral suppression was not found to be significantly associated with adherence defined by any single measure, treatment adherence could be predicted if all three measures were in agreement.

Abstract
Despite well-established strategies to decrease the mother-to-child transmission of HIV-1, new perinatal infections continue to occur globally, reflecting marked disparities in access to health care. Once HIV-1 infection has been established in an infant, the combination of early initiation of antiretroviral therapy and prophylaxis against Pneumocystis jiroveci pneumonia is paramount to reducing disease progression. This article reviews the recommendations and evidence for the treatment of HIV-1-infected infants.

Abstract
The objective of this document is to identify and reinforce current recommendations concerning the management of HIV infection in infants and children in the context of good resource availability. All recommendations were graded according to the strength and quality of the evidence and were voted on by the 57 participants attending the first Italian Consensus on Paediatric HIV, held in Siracusa in 2008. Paediatricians and HIV/AIDS care specialists were requested to agree on different statements summarizing key issues in the management of paediatric HIV. The comprehensive approach on preventing mother-to-child transmission (PMTCT) has clearly reduced the number of children acquiring the infection in Italy. Although further reduction of MTCT should be attempted, efforts to personalize intervention to specific cases are now required in order to optimise the treatment and care of HIV-infected children. The prompt initiation of treatment and careful selection of first-line regimen, taking into consideration potency and tolerance, remain central. In addition, opportunistic infection prevention, adherence to treatment, and long-term psychosocial consequences are becoming increasingly relevant in the era of effective antiretroviral combination therapies (ART). The increasing proportion of infected children achieving adulthood highlights the need for multidisciplinary strategies to facilitate transition to adult care and maintain strategies specific to perinatally acquired HIV infection.

Abstract
BACKGROUND South African guidelines recommend protease-inhibitor-based antiretroviral therapy (ART) with lopinavir-ritonavir for human immunodeficiency virus (HIV)-infected children <36 months of age. We investigated factors associated with viral suppression and mortality among young children initiating ART. METHODS Treatment-naive, ART-eligible, HIV-infected children (aged 6-104 weeks) were enrolled in an ART strategies trial in South Africa and initiated protease-inhibitor-based ART. Mortality and the probability of viral suppression (defined as HIV RNA load of <400 copies/mL) by 39 weeks after ART initiation were investigated. RESULTS Of 254 children who initiated ART, 99 (39%) were cotreated for tuberculosis during follow-up. The mortality rate was 14%. Factors predicting mortality were lower pre-ART weight-for-age z score and higher HIV RNA load. By 39 weeks, 84% of surviving children achieved viral suppression. Children who were not cotreated for tuberculosis were more likely to achieve viral suppression (94.8%) than were children who were receiving cotreatment at ART initiation (74.2%) or who started tuberculosis cotreatment after ART initiation (51.6%; P < .001). Other factors predicting lower probability of viral suppression were lower pre-ART weight- and length-for-age z score, higher HIV RNA load, and World Health Organization disease stage. CONCLUSION High rates of viral suppression can be achieved among infants and young children who initiate protease-inhibitor-based ART. Cotreatment for tuberculosis reduced viral suppression. How best to treat HIV-infected children who require tuberculosis treatment warrants urgent investigation.

Abstract
To improve upon adherence assessment in children with HIV, multimethod adherence strategies (pill count, missed doses, off-schedule dosing) were conducted concurrent with viral load and CD4% biomarker assays. Off-schedule dosing predicted both health status markers, while the more common strategies did not. Findings support inclusion of off-schedule dosing concurrent with collection of biomarkers to assess adherence in children with HIV.

Didanosine population pharmacokinetics in West African human immunodeficiency virus-infected children administered once-daily tablets in relation to efficacy after one year of treatment. Antimicrob Agents Chemother 2009; 53:4399-406. [PMID: 19581461 PMCID: PMC2764159 DOI: 10.1128/aac.01187-08] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2008] [Revised: 01/08/2009] [Accepted: 06/25/2009] [Indexed: 11/20/2022] Open
Abstract
Our objective was to study didanosine pharmacokinetics in children after the administration of tablets, the only formulation available in Burkina Faso for which data are missing, and to establish relationships between doses, plasma drug concentrations, and treatment effects (efficacy/toxicity). Didanosine concentrations were measured for 40 children after 2 weeks and for 9 children after 2 to 5 months of treatment with a didanosine-lamivudine-efavirenz combination. A population pharmacokinetic model was developed with NONMEM. The link between the maximal concentration of the drug in plasma (Cmax), the area under the concentration-time curve (AUC), and the decrease in human immunodeficiency virus (HIV) type 1 RNA levels after 12 months of treatment was evaluated. The threshold AUC that improved efficacy was determined by the use of a Wilcoxon test for HIV RNA, and an optimized dosing schedule was simulated. Didanosine pharmacokinetics was best described by a one-compartment model with first-order absorption and elimination. The apparent clearance and volume of distribution were higher for tablets, probably due to a lower bioavailability with tablets than with pediatric powder. The decrease in the viral load after 12 months of treatment was significantly correlated with the didanosine AUC and Cmax (P < or = 0.02) during the first weeks of treatment. An AUC of >0.60 mg/liter x h was significantly linked to a greater decrease in the viral load (a decrease of 3 log10 versus 2.4 log10 copies/ml; P = 0.03) than that with a lower AUC. A didanosine dose of 360 mg/m2 administered as tablets should be a more appropriate dose than 240 mg/m2 to improve efficacy for these children. However, data on adverse events with this dosage are missing.

Abstract
OBJECTIVE To test predictors of medication adherence in high-risk racial or ethnic minority youth living with HIV (YLH) using a conceptual model of social cognitive predictors including a continuous measure of motivational readiness. METHODS Youth were participants in a multi-site clinical trial examining the efficacy of a motivational intervention. Racial-minority YLH (primarily African American) who were prescribed antiretroviral medication were included (N = 104). Data were collected using computer-assisted personal interviewing method via an Internet-based application and questionnaires. RESULTS Using path analysis with bootstrapping, most youth reported suboptimal adherence, which predicted higher viral load. Higher motivational readiness predicted optimal adherence, and higher social support predicted readiness. Decisional balance was indirectly related to adherence. CONCLUSIONS The model provided a plausible framework for understanding adherence in this population. Culturally competent interventions focused on readiness and social support may be helpful for improving adherence in YLH.

Abstract
BACKGROUND Alterations in regional fat are often reported in HIV infection. Prior studies have not distinguished between normal changes in regional fat related to sexual maturation and those due to HIV. The study aim was to compare changes in regional fat distribution in HIV-infected (HIV+) and healthy (HIV-) children and adolescents living in the United States. METHODS Serial dual energy X-ray absorptiometry was performed at baseline and two annual follow-up visits in 64 HIV+ and 147 HIV--participants aged 6-16 years. Total, leg, arm, and trunk fat masses (kg) and regional fat distribution as the percentage of total body fat (%) were compared. RESULTS HIV+ and HIV--participants did not differ in total fat mass, but the HIV+ group had significantly lower leg and greater arm fat and trunk fat percentage at all time points. Over time, decreases in leg fat percentage and increases in arm fat percentage were more marked among the HIV+ group. Differences between HIV+ and HIV--groups in arm and leg fat percentage remained significant when age, sex, race, height, and pubertal stage were accounted for by mixed effect modeling. Apart from prior treatment with stavudine, no differences in fat distribution were observed according to treatment or degree of immunodeficiency or viremia. CONCLUSION Although no single pattern of change in regional fat distribution was uniquely associated with HIV, perinatally HIV-infected youth manifest significantly decreased leg fat and increased arm and trunk fat. These differences increase over time and may contribute to cardiovascular disease risk.

Abstract
Background Ensuring good adherence is critical to the success of anti-retroviral treatment (ART). However, in resource-poor contexts, where paediatric HIV burden is high there has been limited progress in developing or adapting tools to support adherence for HIV-infected children on ART and their caregivers. We conducted formative research to assess children's adherence and to explore the knowledge, perceptions and attitudes of caregivers towards children's treatment. Methods All children starting ART between September 2002 and January 2004 (when ART was at cost in Malawi) were observed for at least 6 months on ART. Their adherence was assessed quantitatively by asking caregivers of children about missed ART doses during the previous 3 days at monthly visits. Attendance to clinic appointments was also monitored. In June and July 2004, four focus group discussions, each with 6 to 8 caregivers, and 5 critical incident narratives were conducted to provide complementary contextual data on caregivers' experiences on the challenges to and opportunities of paediatric ART adherence. Results We followed prospectively 47 children who started ART between 8 months and 12 years of age over a median time on ART of 33 weeks (2–91 weeks). 72% (34/47) never missed a single dose according to caregivers' report and 82% (327/401) of clinic visits were either as scheduled, or before or within 1 week after the scheduled appointment. Caregivers were generally knowledgeable about ART and motivated to support children to adhere to treatment despite facing multiple challenges. Caregivers were particularly motivated by seeing children begin to get better; but faced challenges in meeting the costs of medicine and transport, waiting times in clinic, stock outs and remembering to support children to adhere in the face of multiple responsibilities. Conclusion In the era of rapid scale-up of treatment for children there is need for holistic support strategies that focus on the child, the caregiver and the health worker and which are situated within the reality of fragile health systems. The findings highlight the need for cost-free and less complex paediatric ART regimes and culturally appropriate tools to support children's adherence.

Abstract
The long-term impact of highly active antiretroviral therapy (HAART) on HIV-1 infected children is not well known. The Danish Paediatric HIV Cohort Study includes all patients <16 y of age with HIV-1 infection in Denmark. We report the complete follow-up from 1996 to 2005 of 49 perinatally infected children treated with HAART. Initial HAART included 2 nucleoside reverse-transcriptase inhibitors in combination with either a protease inhibitor (n =38) or a non-nucleoside reverse-transcriptase inhibitor (n =12). 19 (39%) patients were previously treated with mono- or dual therapy. Baseline characteristics were median CD4 percentage 14% and HIV-RNA viral load 4.9 log(10). Within the first 12 weeks of therapy approximately 60% achieved HIV-RNA viral load <500 copies/ml, and this remained stable for up to 8 y, although many children changed the components of HAART. The proportion of children with CD4 percentage >25% increased to 60-70% over the y of treatment. For the total cohort, 245 patient-y of observation were available with only 1 death. During our observation period there were no signs of a waning impact. The challenge remains to maintain a high adherence to therapy as the children grow into adolescence and develop more independence from family and health care staff.

Abstract
Background As highly active antiretroviral therapy (HAART) becomes increasingly available to African children, it is important to evaluate simple and feasible methods of improving adherence in order to maximize benefits of therapy. Methods HIV-1-infected children initiating World Health Organization non-nucleoside reverse transcriptase-inhibitor-containing first-line HAART regimens were randomized to use medication diaries plus counselling, or counselling only (the control arm of the study). The diaries were completed daily by caregivers of children randomized to the diary and counselling arm for nine months. HIV-1 RNA, CD4+ T cell count, and z-scores for weight-for-age, height-for-age and weight-for-height were measured at a baseline and every three to six months. Self-reported adherence was assessed by questionnaires for nine months. Results Ninety HIV-1-infected children initiated HAART, and were followed for a median of 15 months (interquartile range: 2–21). Mean CD4 percentage was 17.2% in the diary arm versus 16.3% in the control arm at six months (p = 0.92), and 17.6% versus 18.9% at 15 months (p = 0.36). Virologic response with HIV-1 RNA of <100 copies/ml at nine months was similar between the two arms (50% for the diary arm and 36% for the control, p = 0.83). The weight-for-age, height-for-age and weight-for-height at three, nine and 15 months after HAART initiation were similar between arms. A trend towards lower self-reported adherence was observed in the diary versus the control arm (85% versus 92%, p = 0.08). Conclusion Medication diaries did not improve clinical and virologic response to HAART over a 15-month period. Children had good adherence and clinical response without additional interventions. This suggests that paediatric HAART with conventional counselling can be a successful approach. Further studies on targeted approaches for non-adherent children will be important.

Abstract
Research on adults with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has suggested that psychiatric and substance abuse comorbidities are prevalent in this population, and that these may sometimes be associated with use of antiretroviral therapy (ART) and adherence. For adolescents with HIV/AIDS, much less is known about patterns of mental health comorbidity, and even fewer data are available that compare them to socioeconomically comparable youth without HIV/AIDS. Using medical and pharmacy data from 1999 to 2000 Medicaid claims (Medicaid Analytic Extract) from 4 states for beneficiaries aged 12 to 17 years, we identified 833 youth under care for HIV/AIDS meeting study criteria within the HIV/AIDS group, receipt of ART was less likely for youth who had diagnoses of substance abuse, conduct disorders, or emotional disorders than for others. Once ART was initiated, adherence did not significantly differ between adolescents living with a psychiatric condition, and those who were not, with the exception of an association between conduct disorder and lower adherence. Among those with HIV/AIDS, ART use and adherence were more common among youth with higher rates of service use, regardless of psychiatric status. Associations between race and adherence varied by gender: compared with their white counterparts, minority girls had lower, and minority boys had higher adherence.

Abstract
Children and families bear a significant burden of human immunodeficiency virus disease globally, particularly in sub-Saharan Africa. Care of severely affected families can be adversely impacted by high medication burdens and overwhelmed caregivers, who themselves may be human immunodeficiency virus infected. Family-centered care involving joint clinic days, treatment preparation, adherence counseling, and community-based follow-up may improve the care of family units. We describe the successful treatment of a single family composed of 6 infected members living in a rural African setting.

Abstract
Background The introduction of combination antiretroviral therapy (ART) has resulted in striking reductions in HIV-related mortality. Despite increased availability of ART, children remain a neglected population. This may be due to concerns that failure to adhere appears to be related to continued viral replication, treatment failure and the emergence of drug-resistant strains of HIV. This study determines the rates and factors associated with adherence to Antiretroviral (ARV) Drug therapy in HIV-infected children who were receiving Highly Active Antiretroviral Therapy (HAART) in Addis Ababa, Ethiopia in 2008. Methods A cross-sectional study was conducted in five hospitals in Addis Ababa from February 18 – April 28, 2008. The study population entailed parents/caretaker and index children who were following ART in the health facilities. A structured questionnaire was used for data collection. Results A total of 390 children respondents were included in the study with a response rate of 91%. The majority, equaling 205 (52.6%) of the children, were greater than 9 years of age. Fifty five percent of the children were girls. A total of 339 children (86.9%) as reported by caregivers were adherent to antiretroviral drugs for the past 7 days before the interview. Numerous variables were found to be significantly associated with adherence: children whose parents did not pay a fee for treatment [OR = 0.39 (95%CI: 0.16, 0.92)], children who had ever received any nutritional support from the clinic [OR = 0.34 (95%CI: 0.14, 0.79)] were less likely to adhere. Whereas children who took co-trimoxazole medication/syrup besides ARVs [OR = 3.65 (95%CI: 1.24, 10.74)], children who did not know their sero-status [OR = 2.53 (95%CI: 1.24, 5.19)] and children who were not aware of their caregiver's health problem [OR = 2.45 (95%CI: 1.25, 4.81)] were more likely to adhere than their counterparts. Conclusion Adherence to HAART in children in Addis Ababa was higher than other similar setups. However, there are still significant numbers of children who are non-adherent to HAART.

Abstract
Abstract Survival among perinatally infected children and youth with HIV has been greatly extended since the advent of highly active antiretroviral therapies. Yet, adherence to HIV medication regimens is suboptimal and decreases as children reach adolescence. This paper reports on a qualitative study examining psychosocial factors associated with adherence among perinatally infected youth ages 10-16 years. The study was based on in-depth interviews with a sample of 30 caregivers participating in a comprehensive health care program in New York City serving families with HIV. A subsample comprising 14 caregivers of children ages 10 and above is the focus of this paper. The analysis identified a number of themes associated with the psychosocial context of managing adherence among older children. Maintaining adherence was an ongoing challenge and strategies evolved as children matured. Regimen fatigue and resistance to taking the medications were major challenges to maintaining adherence among the oldest children. In other cases, caregivers developed a kind of partnership with their child for administering the medications. Disclosure to the child of his or her HIV status was used as a strategy to promote adherence but seemed to be effective only under certain circumstances. Social support appeared to have an indirect influence on adherence, primarily by providing caregivers with temporary help when needed. Health care professionals were an important source of disclosure and adherence support for parents. The study illustrates the interplay of maturational issues with other contextual psychosocial factors as influences on adherence among older children and adolescents.

Abstract
OBJECTIVE We aimed to evaluate clinical and immunological outcomes of paediatric patients receiving combination antiretroviral therapy (cART) enrolled in The AIDS Support Organization (TASO) Uganda national HIV/AIDS programme. DESIGN Observational study of patients (age <14 years) enrolled in 10 clinics across Uganda for which TASO has data. METHODS We extracted patient demographic, immunological and clinical outcomes from the TASO databases regarding age, sex, cART regimen, CD4 cell count and WHO stage at initiation, tuberculosis, mortality and adherence. Outcomes were analysed using Pearson's rank-order correlations, Wilcoxon's rank sum tests, Cox proportional hazard model and survivor functions. RESULTS Of the total 770 HIV children on cART, median age was 9 years (interquartile range, 5-13 years), and median follow-up time was 377 days (interquartile range, 173-624 days). Seven hundred and fifty-one children (97.5%) initiated nonnucleoside reverse transcriptase inhibitor-based regimens. Three hundred and sixty-five children (47.5%) initiated cART with severe immune suppression (CD4 cell percentage <15). Of the 18 (2.3%) children that died, mortality was associated with lower CD4 cell percentage at initiation (B coefficient -0.144, standard error 0.06, P = 0.02). Of the total, 229 (30%) were single or double orphans and more likely to initiate cART at an older age (mean age, 9.25 vs. 8.35 years, P = 0.02) and have a lower CD4 cell count (median, 268 vs. 422 cells/microl, P < or = 0.0001) and CD4 cell percentage (median 12.8 vs. 15.5%, P = 0.02) at initiation. Pulmonary tuberculosis was present in 43 (5.6%) patients at initiation and 21 (2.3%) after cART. Almost all patients (94.9%) demonstrated more than 95% adherence. CONCLUSION Children on cART in Uganda demonstrate positive clinical outcomes. However, additional support is required to ensure timely cART access among orphans and young children.

Abstract
BACKGROUND Antiretroviral therapy (ART) dramatically improves outcomes for children in Africa; however excellent adherence is required for treatment success. This study describes the utility of different measures of adherence in detecting lapses in infants and young children in Cape Town, South Africa. METHODS In a prospective cohort of 122 HIV-infected children commenced on ART, adherence was measured monthly during the first year of treatment by medication return (MR) for both syrups and tablets/capsules. A questionnaire was administered to caregivers after 3 months of treatment to assess experience with giving medication and self-reported adherence. Viral and immune response to treatment were assessed at the end of one year and associations with measured adherence determined. RESULTS Medication was returned for 115/122 (94%) children with median age (IQR) of 37 (16-61) months. Ninety-one (79%) children achieved annual average MR adherence > or = 90%. This was an important covariate associated with viral suppression after adjustment for disease severity (OR = 5.5 [95%CI: 0.8-35.6], p = 0.075), however was not associated with immunological response to ART. By 3 months on ART, 13 (10%) children had deceased and 11 (10%) were lost to follow-up. Questionnaires were completed by 87/98 (90%) of caregivers of those who remained in care. Sensitivity of poor reported adherence (missing > or = 1 dose in the previous 3 days) for MR adherence <90% was only 31.8% (95% CI: 10.7%-53.0%). Caregivers of 33/87 (38.4%) children reported difficulties with giving medication, most commonly poor palatability (21.8%). Independent socio-demographic predictors of MR adherence > or = 90% were secondary education of caregivers (OR = 4.49; 95%CI: 1.10-18.24) and access to water and electricity (OR = 2.65; 95%CI: 0.93-7.55). Taking ritonavir was negatively associated with MR adherence > or = 90% (OR = 0.37; 95%CI: 0.13-1.02). CONCLUSION Excellent adherence to ART is possible in African infants and young children and the relatively simple low technology measure of adherence by MR strongly predicts viral response. Better socio-economic status and more palatable regimens are associated with better adherence.
