Quality of life for children and adolescents: impact of HIV infection and antiretroviral treatment

Body composition, physical fitness and physical activity in Mozambican children and adolescents living with HIV

INTRODUCTION

As a result of the effectiveness of antiretroviral drugs (ART), HIV/AIDS has become a chronic disease, which has enabled children living with HIV to reach adolescence and adulthood. However, the long exposure to both the disease and ART has caused undesirable effects that compromise the physiological functioning and the quality of life of the subjects.

OBJECTIVE

To determine the body composition, physical fitness and habitual physical activity of children and adolescents living with HIV on ART.

METHODS

A total of 79 subjects of both genders aged 8-14 years, living with HIV in ART, selected by convenience participated in the study. The subjects underwent anthropometric assessment, physical fitness assessment and physical activity assessment.

RESULTS

Relative to reference norms, the values of the anthropometric indicators fell below 50th percentile (height/age = 92.4%; BMI/age 72.2%; sum of skinfolds = 51.9%; arm circumference = 63.3%). The prevalence of "low height/age" and "low weight/age" was 34.9% and 9.3%, respectively for boys, and 27.9% and 11.1%, respectively for girls. With the exception of trunk flexibility (12.3%), most subjects were considered unfit in the physical fitness tests (abdominal resistance = 76.4%; handgrip strength = 75.4%; lower limb power = 66.4%). The percentage of subjects with insufficient physical activity was 45.5% for boys and 77.8% for girls. The values for all variables were consistently and significantly lower when compared with studies done in Mozambicans boys and girls without HIV+ from both urban and rural areas.

CONCLUSION

The subjects participants in the study living with HIV and undergoing ART had impaired growth, low physical fitness and low levels of habitual physical activity in relation to the reference values of their peers without HIV, which compromised their physiological functioning and their quality of life.

Psychiatric Comorbidities in Pediatric Inpatients With Human Immunodeficiency Virus Infection and Impact on Hospital Course: Inputs From a Case-Control Inpatient Study

Objectives In this study, we aimed to delineate psychiatric comorbidities in pediatric inpatients with versus without human immunodeficiency virus (HIV) infection and to measure its impact on the length of stay (LOS) and cost of treatment during hospitalization. Methodology We conducted a case-control study using the Nationwide Inpatient Sample and included 4,920 pediatric inpatients between the ages of six and 18 years who were sub-grouped by a comorbid diagnosis of HIV (N = 2,595) and non-HIV (N = 2,325) and matched for demographics (age, sex, and race) by propensity case-control matching. Logistic regression analyses were used to evaluate the adjusted odds ratio (aOR) of association for psychiatric comorbidities (depression, anxiety, post-traumatic stress disorder, psychosis, and drug abuse) in the HIV-positive compared with the HIV-negative (as reference category) pediatric inpatients. We measured the differences in the LOS and cost using the independent sample t-test. Results We found that the most prevalent psychiatric comorbidities in the HIV-positive group were anxiety (6.9%), drug abuse (6.6%), psychosis (6.4%), and depression (6.2%). The HIV-positive group had a significantly higher likelihood of comorbid psychosis (aOR: 1.82; 95% confidence interval [CI]: 1.38-2.40) and depression (aOR: 1.79; 95% CI: 1.36-2.36). The mean LOS per hospitalization episode was longer for the HIV-positive group (11.1 days vs. 6.0 days; P < 0.001) compared to the HIV-negative pediatric inpatients. Conclusions We found an increased risk of depression by 79% and psychosis by 82% in the HIV-positive pediatric population. These inpatients also had an extended hospitalization stay (by five days), adding to the healthcare economic burden.

Health-related quality of life of perinatally HIV-infected young people: a longitudinal study

Young people perinatally infected with HIV (pHIV) are at risk of a lowered health-related quality of life (HRQOL). Previous evaluation of the NeurOlogical, VIsual and Cognitive performance in HIV-infected Children (NOVICE)-cohort showed no difference in HRQOL between pHIV and matched HIV-uninfected controls (HIV-), yet a higher percentage of pHIV had impaired HRQOL. The aim of this study is to compare the change over time in HRQOL of pHIV to HIV- over a 5-year period. We used the Pediatric Quality of Life Inventory (PedsQL)™ 4.0 to repeat HRQOL assessment. High PedsQL scores indicate good HRQOL. Fifteen/33 (45.5%) pHIV and 17/37 (45.9%) HIV- completed both assessments. At the first assessment, the mean age was 13.1 years (range 8.0-18.4). PHIV scored higher than HIV- on Emotional functioning and on Total scale score. After five years, the mean age was 17.6 years (range 12.1-22.8). PHIV scored higher than HIV- on all scales, except Social functioning. PHIV did not differ significantly from the Dutch norm on either time-point. LMEM showed no difference in change over time for any of the PedsQL scales. In this study, young people with pHIV receiving high-quality health care, including monitoring of HRQOL, remain to experience a good HRQOL.

White matter of perinatally HIV infected older youths shows low frequency fluctuations that may reflect glial cycling

In perinatally HIV-infected (PHIV) children, neurodevelopment occurs in the presence of HIV-infection, and even with combination antiretroviral therapy (cART) the brain can be a reservoir for latent HIV. Consequently, patients often demonstrate long-term cognitive deficits and developmental delay, which may be reflected in altered functional brain activity. Our objective was to examine brain function in PHIV on cART by quantifying the amplitude of low frequency fluctuations (ALFF) and regional homogeneity (ReHo). Further, we studied ALFF and ReHo changes with neuropsychological performance and measures of immune health including CD4 count and viral loads in the HIV-infected youths. We found higher ALFF and ReHo in cerebral white matter in the medial orbital lobe for PHIV (N = 11, age mean ± sd = 22.5 ± 2.9 years) compared to controls (N = 16, age = 22.5 ± 3.0 years), with age and gender as co-variates. Bilateral cerebral white matter showed increased spontaneous regional activity in PHIV compared to healthy controls. No brain regions showed lower ALFF or ReHo in PHIV compared to controls. Higher log10 viral load was associated with higher ALFF and ReHo in PHIV in bilateral cerebral white matter and right cerebral white matter respectively after masking the outcomes intrinsic to the brain regions that showed significantly higher ALFF and ReHo in the PHIV compared to the control. Reductions in social cognition and abstract thinking in PHIV were correlated with higher ALFF at the left cerebral white matter in the left medial orbital gyrus and higher ReHo at the right cerebral white matter in the PHIV patients. Although neuroinflammation and associated neuro repair were not directly measured, the findings support their potential role in PHIV impacting neurodevelopment and cognition.

Behavioral Functioning and Quality of Life in South African Children Living with HIV on Antiretroviral Therapy

This study examined behavioral functioning and quality of life in South African children living with perinatally acquired HIV. Compared with controls, children living with perinatally acquired HIV had a higher mean total difficulties score assessed by the Strengths and Difficulties Questionnaire and lower mean quality of life scores assessed by the Pediatric Quality of Life Inventory.

Validation of an HIV/AIDS Stigma Measure for Children Living with HIV and Their Families

BACKGROUND

There are few validated tools to measure stigma, particularly among children living with HIV and their families.

METHODS

This study was nested within a larger study that followed 240 child-caregiver dyads (children aged 10-15 years) at 8 clinics in western Kenya. The stigma instrument was administered to all child-caregiver dyads at 2 time points 6 months apart. The primary end point was to construct validity assessed by comparison to criterion constructs using generalized estimating equation models.

RESULTS

Mean age of child participants was 12.3 years and 52% were female. Generally, caregivers reported experiencing higher levels of HIV stigma compared to their children. Children (9%) and caregivers (14%) reported that HIV stigma made them feel stressed, anxious, and depressed. Child and caregiver stigma items showed high construct validity by emotional and behavioral outcomes.

CONCLUSIONS

The stigma instrument showed high validity when compared to emotional and behavioral outcomes.

Toxic Stress and Quality of Life in Early School-Aged Ugandan Children With and Without Perinatal Human Immunodeficiency Virus Infection

Caregiver's and child's self-reported quality of life (QOL) was defined using standardized questionnaires in a sample (N = 277) of 6-10 years old HIV-infected, HIV-exposed uninfected, and HIV-unexposed uninfected children from Uganda. Psychosocial stress (acute stress and cumulative lifetime adversity) and physiologic stress (dysregulations across 13 biomarkers), perinatal HIV status, and their interaction were related to child QOL via general linear models. Lower child- and caregiver-reported psychosocial stress were dose-dependently associated with higher QOL (acute stress: mean difference coefficient b = 8.1-14.8, effect size [ES] = 0.46-0.83). Lower allostasis was dose-dependently associated with higher QOL (b = 6.1-9.7, ES = 0.34-0.54). Given low caregiver acute stress, QOL for HIV-infected was similar to HIV-uninfected children; however, given high caregiver acute stress, a QOL disadvantage (b = -7.8, 95% CI: -12.8, -2.8; ES = -0.73) was evident for HIV-infected versus uninfected children. Testing of caregiver stress reduction interventions is warranted to increase wellbeing in dependent children.

Caries experience and oral health related quality of life in a cohort of Ugandan HIV-1 exposed uninfected children compared with a matched cohort of HIV unexposed uninfected children

Background

Very few studies consider the oral health status and quality of life in HIV-1 exposed uninfected (HEU) children. The aim of this study was to estimate the prevalence of caries in primary teeth and its oral health related quality of life impacts in HEU children compared to HIV-unexposed-uninfected (HUU) children, whilst adjusting for confounding covariates.

Methods

This study uses data from the Ugandan site of the ANRS 121741 PROMISE- PEP trial (ClinicalTrials.gov, number NCT00640263) conducted in 2009–2013 that recruited mothers with HIV-1 and their uninfected children. Of 244 HEU-children-caretaker pairs available at the end of the one-year trial, 166 were re-enrolled in the ANRS 12341 PROMISE-PEP M&S study at 5–7 years and 164 were included in this study. These were age and sex-matched with 181 HUU children-caretaker comparators. Caries experience was recorded using World Health Organization’s Decayed, Missed and Filled teeth (dmft/DMFT) indices. The Early Childhood Oral health Impact Scale (ECOHIS) was used for assessment of oral health related quality of life. Mixed effects logistic regression was conducted with dmft and ECOHIS scores as outcomes and HIV-1 exposure status as the main exposure.

Results

Forty-eight percent of HEU children and 60% of HUU had dmft> 0. Corresponding figures for ECOHIS> 0 were 12% of HEU and 22% of HUU. The crude analysis showed differences related to HIV-1 exposure in caries experience and oral health related quality of life. Mixed effect logistic regression analyses were not significant when adjusted for use of dental care and toothache. If caregivers’ DMFT> 0, the adjusted odds ratio for caries experience (dmft> 0) was 1.6 (95% CI: 1.0–2.8) while if dmft> 0 the adjusted odds ratio for quality of life impacts (ECOHIS> 0) was 4.6 (95% CI: 2.0–10.6).

Conclusion

The prevalence of untreated caries in primary teeth and quality of life impacts was high in this study population. HIV-1 exposed uninfected children were not more likely than HUU children to experience dental caries or have impaired oral health related quality of life. Given the global expansion of the HEU child population, the present findings indicating no adverse effect of pre- and post-natal HIV-1 exposure on caries in deciduous teeth are reassuring.

Health-related quality of life in Polish children and adolescents with perinatal HIV infection - short report

The aims of the study were to assess health-related quality of life (HRQoL) in children and adolescents with perinatal HIV infection and to establish possible relationships with clinical and socio-demographic variables. About 56 children with perinatal HIV infection, aged 6-18 years (PHIV+ group), 24 healthy perinatally HIV-exposed but uninfected (PHEU) children, and 43 children HIV-unexposed uninfected (HUU) were assessed using the PedsQL 4.0. Generic Core. The perceptions of school functioning according to children and social functioning, according to parents, were worse in the PHIV+ group compared to those in the PHEU group. In comparison to the HUU group, PHIV+ children received lower total HRQoL scores in the caregivers' perception. Most of the life-quality indices increased systematically with age in PHIV+ group, whereas opposite trends were present in both control groups. Caregivers of children with a final CDC category C and caregivers of children diagnosed with encephalopathy perceived most domains of their children functioning as more problematic. A more serious course and more severe HIV infection before treatment were associated with worse multidimensional functioning and a worse total HRQoL score. Results highlight the importance of early diagnosis and treatment initiation as having significant implications for the quality of life.

White matter microstructure among perinatally HIV-infected youth: a diffusion tensor imaging study

We evaluated white matter microstructure integrity in perinatally HIV-infected (PHIV) youths receiving cART compared to age- and gender-matched healthy youths through DTI metrics using voxel-based morphometry (VBM). We investigated 14 perinatally HIV-infected patients (age 17.9 ± 2.5 years) on cART and 17 healthy youths (HC) (age 18.0 ± 3.0 years) using a 3T MRI scanner. Four DTI-derived metrics were fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD). Statistical analysis was done with voxel-based analysis of covariance (ANCOVA), with age and gender as covariates. Region-of-interest secondary analyses in statistically significant regions were also performed. Regional increases in FA in the PHIV youths were found in left middle frontal gyrus, right precuneus, right lingual gyrus, and left supramarginal gyrus. Increased MD was found in the right precentral gyrus while decreased MD was found in the white matter of the right superior parietal lobule and right inferior temporal gyrus/fusiform gyrus. Regions of increased/decreased RD overlapped with regions of increased/decreased MD. Both increased and decreased AD were found in three to four regions respectively. The regional FA, MD, RD, and AD values were consistent with the voxel-based analysis findings. The findings are mostly consistent with previous literature, but increased FA has not been previously reported for perinatally HIV-infected youths. Potentially early and prolonged therapy in our population may have contributed to this new finding. Both toxicity of antiretroviral therapy and indolent infection must be considered as causative factors in the DTI metric changes that we have observed.

Characteristics of HIV-infected adolescents enrolled in a disclosure intervention trial in western Kenya

Knowledge of one's own HIV status is essential for long-term disease management, but there are few data on how disclosure of HIV status to infected children and adolescents in sub-Saharan Africa is associated with clinical and psychosocial health outcomes. We conducted a detailed baseline assessment of the disclosure status, medication adherence, HIV stigma, depression, emotional and behavioral difficulties, and quality of life among a cohort of Kenyan children enrolled in an intervention study to promote disclosure of HIV status. Among 285 caregiver-child dyads enrolled in the study, children's mean age was 12.3 years. Caregivers were more likely to report that the child knew his/her diagnosis (41%) compared to self-reported disclosure by children (31%). Caregivers of disclosed children reported significantly more positive views about disclosure compared to caregivers of non-disclosed children, who expressed fears of disclosure related to the child being too young to understand (75%), potential psychological trauma for the child (64%), and stigma and discrimination if the child told others (56%). Overall, the vast majority of children scored within normal ranges on screenings for behavioral and emotional difficulties, depression, and quality of life, and did not differ by whether or not the child knew his/her HIV status. A number of factors were associated with a child's knowledge of his/her HIV diagnosis in multivariate regression, including older age (OR 1.8, 95% CI 1.5-2.1), better WHO disease stage (OR 2.5, 95% CI 1.4-4.4), and fewer reported caregiver-level adherence barriers (OR 1.9, 95% CI 1.1-3.4). While a minority of children in this cohort knew their HIV status and caregivers reported significant barriers to disclosure including fears about negative emotional impacts, we found that disclosure was not associated with worse psychosocial outcomes.

A study of neuropsychological profile of human immunodeficiency virus-positive children and adolescents on antiretroviral therapy

AIMS

The aim is to study the neuropsychological and functional profile of children and adolescents with human immunodeficiency virus (HIV) infection on antiretroviral therapy (ART) and the association between the neuropsychological status and medical illness variables, treatment variables, and functional status in the cases of the sample and compare with normal controls.

MATERIALS AND METHODS

Forty-two HIV-positive children and adolescents on ART were evaluated and compared with 40 matched controls not known to be HIV-positive. The tools used were the Wechsler Intelligence Scale for Children-III R for neuropsychological evaluation, the Brief Impairment Scale to assess functional impairment, and a semi-structured questionnaire to obtain other relevant details.

RESULTS

There were significant differences between the verbal, performance intelligence quotients (IQs), global IQ score, and several individual subtests between cases and controls. The HIV group was also found to have a significant functional impairment.

CONCLUSION

Our findings show that HIV infection is associated with significant cognitive and functional impairment. The role of ART in these impairments requires further study. Such understanding can help to introduce wholesome and relatively safer management strategies for youngsters with HIV infection and improve their quality of life.

Impact of care at foster homes on the health-related quality of life of HIV-infected children and adolescents: a cross-sectional study from India

PURPOSE

To assess the impact of care at foster homes on the health-related quality of life (HRQOL) of children living with HIV (CLHIV), attending a referral ART Centre, and to compare their HRQOL with children living in their own homes.

METHODS

A cross-sectional study was conducted in 144 CLHIV between 5 and 18 years of age, attending a referral ART Centre in South India to assess their HRQOL using the standard PedsQL™ 4.0 questionnaire. Data were then analysed to compare the HRQOL of children living in foster homes to those children living in their own homes. The child report and the parent proxy-report on the child's HRQOL were also compared to see for any differences in their perspectives.

RESULTS

56.25% CLHIV were brought up in different foster homes. In the child's self-report, the mean HRQOL was higher for children living in foster homes [physical score (76.54 ± 12.40), psychosocial score (71.41 ± 12.40) and total score (73.20 ± 11.13)] when compared to children living in their own homes [physical score (75.09 ± 14.76), psychosocial score (70.60 ± 13.48) and total score (72.17 ± 12.00)]. There was no statistically significant difference in the HRQOL between these two groups (p > 0.05). In the parent proxy-report also, there was no statistically significant difference in the HRQOL in all the three scores. The child self-report depicted a significantly higher HRQOL in all the domains compared to the parent proxy-report (p < 0.05).

CONCLUSIONS

HRQOL of children living in foster homes is at par with the quality of life enjoyed by children living in their own homes. Foster care manages to provide a reasonable HRQOL in CLHIV, and has become an inseparable component of quality health care delivery for these children.

Quality of life among perinatally HIV-affected and HIV-unaffected school-aged and adolescent Ugandan children: a multi-dimensional assessment of wellbeing in the post-HAART era

OBJECTIVE

To examine quality of life (QOL) in perinatally HIV-infected (PHIV) or HIV-exposed uninfected (PHEU) vs. healthy HIV-unexposed uninfected (HUU) children during school-age/adolescence.

METHODS

PHIV infection was diagnosed via DNA PCR. Current HIV status was confirmed by HIV rapid diagnostic test. Three HIV groups were defined: PHIV, PHEU, and HUU. QOL was assessed with proxy and self-report versions of the PedsQL™ 4.0 instrument at 6-18 years of age. QOL scores ranged from zero (least QOL) to 100 (highest QOL) in the following dimensions: combined QOL inventory (CQOLI), multi-dimensional vigor (MDV), general wellbeing (GWB), present functioning, and general cognitive functioning (CF). Multivariable linear regression models estimated HIV-related percent differences (β) in QOL scores and 95% confidence intervals (CI).

FINDINGS

Compared to HUU CQOLI deficits ranged from 6.5 to 9.2% (95% CI -15.4, -1.6), GWB deficit ranged from 6.5 to 10.5% (95% CI -16.0, -1.3), MDV deficit ranged from 6.8 to 11.6% (95% CI -14.5, 0.9), and CF deficit ranged from 9.7 to 13.1% for PHIV children. QOL deficits of similar magnitude and direction in most domains were observed for PHIV compared to PHEU. However, self-reported indicators of GWB (β = -3.5; 95% CI -9.0, 2.0) and present functioning (β = 4.0; 95% CI -4.6, 12.5) were similar for PHIV compared to PHEU. QOL scores were generally similar for PHEU compared to HUU.

CONCLUSION

PHEU and HUU had similar QOL profile but PHIV predicted sustained deficits in multiple QOL domains. PHIV and PHEU children were similar with respect to general wellbeing and present functioning. Psychosocial and scholastic interventions in combination with HIV care are likely to improve QOL in PHIV.

Health-related quality of life (HRQoL) and its correlates among community-recruited children living with HIV and uninfected children born to HIV-infected parents in West Bengal, India

PURPOSE

Helping children living with HIV (CLH) to attain an optimum quality of life is an important goal for HIV programs around the world. Our principal objectives were to determine the association of HIV infection with different domains of health-related quality of life (HRQoL) among 8- to 15-year-old CLH in India and to compare the HRQoL parameters between CLH and HIV-negative children born to HIV-infected parents ("HIV-affected"). We also assessed whether antiretroviral therapy (ART) and CD4 lymphocyte counts were associated with HRQoL among CLH.

METHODS

Using the "Quality of Life (health-related) of Children Living with HIV/AIDS in India" instrument, we interviewed 199 CLH and 194 HIV-affected children from three districts of West Bengal, India. Participants were asked to quantify the difficulties faced by them in six HRQoL domains: physical, emotional, social, school functioning, symptoms, and discrimination.

RESULTS

The mean age of the participants was 11.6 (SD ± 2.5) years. CLH, compared to HIV-affected children, had poorer scores on all HRQoL domains except 'discrimination.' Among CLH, there were no significant differences in HRQoL domain scores (except in the 'discrimination' domain) between ART-treated and -untreated groups. CD4 lymphocyte count was found to be a significant positive predictor of the 'symptom' scale score.

CONCLUSIONS

In India, interventions for CLH mostly focus on biological disease. However, the current study revealed that HRQoL among CLH was much poorer than that of a socio-demographically comparable group. Culturally and developmentally appropriate psychosocial support measures for Indian CLH are urgently needed.

Emotional and behavioral disturbances in school going HIV positive children attending HIV clinic

BACKGROUND

To study the emotional and behavioral disturbances (EBD) in school going HIV positive children attending HIV center in a tertiary care hospital.

METHOD

This cross-sectional study was conducted on 258 HIV infected children between 6 and 16 years of age, 200 were on Anti-retroviral therapy (ART) and 58 were not on ART. They were evaluated for EBD by using Pictorial Pediatric Symptom Checklist (PPSC) screening tool. A cut-off score of 28 was taken as significant for detecting early EBD.

RESULTS

The prevalence of EBD in our study is 11.2%. Demographic and disease related profile were assessed for correlation with EBD. Type of family (p = 0.023), school attendance (p = 0.034), school performance (p = 0.045), and CD4 count (p = 0.015) were detected to have significant association with early manifestation of EBD in the study group.

CONCLUSIONS

HIV positive children who have low CD4 count, poor school attendance, and performance are at a higher risk of being detected with EBD. Screening with PPSC to identify EBD in HIV positive children attending HIV clinic in a hospital setting could help in early diagnosis and management.

Auditory Alterations in Children Infected by Human Immunodeficiency Virus Verified Through Auditory Processing Test

Introduction The auditory system of HIV-positive children may have deficits at various levels, such as the high incidence of problems in the middle ear that can cause hearing loss. Objective The objective of this study is to characterize the development of children infected by the Human Immunodeficiency Virus (HIV) in the Simplified Auditory Processing Test (SAPT) and the Staggered Spondaic Word Test. Methods We performed behavioral tests composed of the Simplified Auditory Processing Test and the Portuguese version of the Staggered Spondaic Word Test (SSW). The participants were 15 children infected by HIV, all using antiretroviral medication. Results The children had abnormal auditory processing verified by Simplified Auditory Processing Test and the Portuguese version of SSW. In the Simplified Auditory Processing Test, 60% of the children presented hearing impairment. In the SAPT, the memory test for verbal sounds showed more errors (53.33%); whereas in SSW, 86.67% of the children showed deficiencies indicating deficit in figure-ground, attention, and memory auditory skills. Furthermore, there are more errors in conditions of background noise in both age groups, where most errors were in the left ear in the Group of 8-year-olds, with similar results for the group aged 9 years. Conclusion The high incidence of hearing loss in children with HIV and comorbidity with several biological and environmental factors indicate the need for: 1) familiar and professional awareness of the impact on auditory alteration on the developing and learning of the children with HIV, and 2) access to educational plans and follow-up with multidisciplinary teams as early as possible to minimize the damage caused by auditory deficits.

Health-related quality of life and mental health indicators in adolescents with HIV compared to a community sample in the Southeastern US

Although many studies have investigated the impact of HIV on cognitive, physical, academic, and psychosocial functioning, little is known about the self-perception of health-related quality of life (HRQOL), subjective well-being (SWB), social-emotional well-being, and psychopathology risks of adolescents with HIV. This study aimed to address gaps in the literature by exploring the psychosocial outcomes of adolescents with HIV from a strength-based assessment approach, as opposed to a traditional deficit-based approach. Specifically, we explored the relationship between HRQOL, SWB, social-emotional strengths, and psychopathology symptoms to develop a more comprehensive understanding of the physical and psychological well-being of adolescents with HIV (n = 42) compared to a community-based sample (n = 42) in the Southeastern US. Participants completed self-report measures, and data were analyzed for significant correlations, group differences between adolescents with HIV and a community-based sample, and social-emotional predictors of physical functioning and SWB. For adolescents with HIV, several HRQOL indicators were positively correlated with life satisfaction and social-emotional strengths indicators and negatively correlated with negative affect and psychopathology symptoms. Additionally, there was a significant main effect of parents' marital status on participants' perceptions of their social functioning and psychopathology symptoms. When differences in parents' marital status were controlled for, the overall mean ratings of participants' HRQOL, SWB, social-emotional strengths, and psychopathology risks did not significantly differ between groups. Furthermore, parents' marital status and self-rated empathy skills significantly predicted physical functioning of adolescents with HIV, but no significant or meaningful variables were found to predict their SWB. These findings highlight the need for further research on the use of a comprehensive assessment framework to enhance our understanding of the overall well-being of adolescents with HIV.

Stimulant Medications and Cognition, Behavior and Quality of Life in Children and Youth with HIV

BACKGROUND

Limited empirical investigation exists into longitudinal changes in cognition, behavior or quality of life (QOL) in children with perinatal HIV who are prescribed stimulants.

METHODS

This study was an analysis of longitudinal data from children age 3-19 years, with perinatal HIV infection, with and without prescriptions for stimulant medications [prescription (PG) and comparison (CG) groups, respectively], matched on age, availability of CD4% and outcome measures of cognition, behavior and QOL. Generalized estimating equation models were used to evaluate effects of stimulant exposure on change in measured outcomes over 3 years of follow-up, adjusting for baseline levels of outcomes and relevant covariates.

RESULTS

Children in both the PG (n = 132) and the CG (n = 392) obtained mean verbal and performance (nonverbal) intelligence quotients (VIQ and PIQ, respectively) in the low-average range for age. At baseline, those in PG demonstrated more frequent signs of hyperactivity, impulsivity and conduct and learning problems than those in CG (P ≤ 0.003 in unadjusted analyses). At follow-up, after adjustment for baseline functioning and other relevant covariates, there were no significant changes from baseline in VIQ or PIQ. Stimulant prescription use, however, was associated with worsening symptoms of hyperactivity (P = 0.01), impulsivity (P = 0.04), learning problems (P < 0.001) and worsening of perceived health status (P < 0.001).

CONCLUSIONS

The results suggest expectations for behavioral improvement may not align well with long-term effects of stimulant prescription use on behavior and QOL in children with HIV. Further research is necessary to determine if there are subsets of children who may benefit from stimulant therapy.

The physical and psychological effects of HIV infection and its treatment on perinatally HIV-infected children

INTRODUCTION

As highly active antiretroviral therapy (HAART) transforms human immunodeficiency virus (HIV) into a manageable chronic disease, new challenges are emerging in treating children born with HIV, including a number of risks to their physical and psychological health due to HIV infection and its lifelong treatment.

METHODS

We conducted a literature review to evaluate the evidence on the physical and psychological effects of perinatal HIV (PHIV+) infection and its treatment in the era of HAART, including major chronic comorbidities.

RESULTS AND DISCUSSION

Perinatally infected children face concerning levels of treatment failure and drug resistance, which may hamper their long-term treatment and result in more significant comorbidities. Physical complications from PHIV+ infection and treatment potentially affect all major organ systems. Although treatment with antiretroviral (ARV) therapy has reduced incidence of severe neurocognitive diseases like HIV encephalopathy, perinatally infected children may experience less severe neurocognitive complications related to HIV disease and ARV neurotoxicity. Major metabolic complications include dyslipidaemia and insulin resistance, complications that are associated with both HIV infection and several ARV agents and may significantly affect cardiovascular disease risk with age. Bone abnormalities, particularly amongst children treated with tenofovir, are a concern for perinatally infected children who may be at higher risk for bone fractures and osteoporosis. In many studies, rates of anaemia are significantly higher for HIV-infected children. Renal failure is a significant complication and cause of death amongst perinatally infected children, while new data on sexual and reproductive health suggest that sexually transmitted infections and birth complications may be additional concerns for perinatally infected children in adolescence. Finally, perinatally infected children may face psychological challenges, including higher rates of mental health and behavioural disorders. Existing studies have significant methodological limitations, including small sample sizes, inappropriate control groups and heterogeneous definitions, to name a few.

CONCLUSIONS

Success in treating perinatally HIV-infected children and better understanding of the physical and psychological implications of lifelong HIV infection require that we address a new set of challenges for children. A better understanding of these challenges will guide care providers, researchers and policymakers towards more effective HIV care management for perinatally infected children and their transition to adulthood.

Health-related quality of life in perinatally HIV-infected children in the Netherlands

Combination antiretroviral therapy (cART) can alter HIV infection in children into a chronic condition. Studies investigating health-related quality of life (HRQoL) in HIV-infected children are scarce, and lacking from Western Europe. This study aimed to compare the HRQoL of clinically stable perinatally HIV-infected children to healthy, socioeconomically (SES)-matched controls as well as the Dutch norm population, and to explore associations between HIV and cART-related factors with HRQoL. HIV-infected and healthy children aged 8-18 years completed the Pediatric Quality of Life Inventory™ 4.0 (PedsQL™). We determined differences between groups on PedsQL™ mean scores, and the proportion of children with an impaired HRQoL per group (≥1 SD lower than the Dutch norm population). Logistic regression models were used to explore associations between disease-related factors and HRQoL impairment. In total, 33 HIV-infected and 37 healthy children were included. There were no differences in the mean PedsQL™ subscales between HIV-infected children and both control groups. The proportion of children with an impaired HRQoL was higher in the HIV-infected group (27%) as compared to the healthy control group (22%) and the Dutch norm (14%) on the school functioning subscale (HIV vs. Dutch norm: P = .045). Mean scores of HRQoL of perinatally HIV-infected children in the Netherlands were not different from a SES-matched control group, or from the Dutch norm population. However, the HIV-infected group did contain more children with HRQoL impairment, suggesting that HIV-infected children in the Netherlands are still more vulnerable to a compromised HRQoL.

Antiretroviral treatment in HIV-1 infected pediatric patients: focus on efavirenz

Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI), used for the treatment of human immunodeficiency virus (HIV)-1 infection. Approved by the US Food and Drug Administration in 1998, its indication was recently extended to include children as young as 3 months of age. The World Health Organization and many national guidelines consider efavirenz to be the preferred NNRTI for first-line treatment of children over the age of 3 years. Clinical outcomes of patients on three-drug antiretroviral regimens which include efavirenz are as good as or better than those for patients on all other currently approved HIV medications. Efavirenz is dosed once daily and has pediatric-friendly formulations. It is usually well tolerated, with central nervous system side effects being of greatest concern. Efavirenz increases the risk of neural tube defects in nonhuman primates and therefore its use during the first trimester of pregnancy is limited in some settings. With minimal interactions with antituberculous drugs, efavirenz is preferred for use among patients with HIV/tuberculosis coinfection. Efavirenz can be rendered inactive by a single point mutation in the reverse transcriptase enzyme. Newer NNRTI drugs such as etravirine, not yet approved for use in children under the age of 6 years, may maintain their activity following development of efavirenz resistance. This review highlights key points from the existing literature regarding the use of efavirenz in children and suggests directions for future investigation.

Simplifying antiretroviral therapy to lopinavir/ritonavir monotherapy did not improve quality of life and therapy adherence in pretreated HIV-infected children

We reported quality of life (QOL) and adherence in HIV-infected children after simplifying the antiretroviral regimen by switching to lopinavir/ritonavir monotherapy (mLPV/r). HIV-infected children with HIV-RNA <50 copies/ml while using second-line double boosted protease inhibitors were switched to mLPV/r. Primary caregivers completed PACTG QOL questionnaires at weeks 0, 48, 96, and 144. Adherence by pill count was performed at every visit. Thirty-eight pretreated HIV-infected Thai children were enrolled. The median (IQR) age was 11.5 (10.2-13.2) years and 53% were female. At enrollment, 34 used LPV/r+saquinavir and four used LPV/r+indinavir. The median (IQR) CD4% was 27 (23-30)%. At week 144, QOL scores were similar to baseline for all domains. A transient increase in the symptoms domain score was seen at week 96 (p=0.01), whereas the physical resilience domain score was decreased at weeks 48 and 96 (both p<0.05). Despite the mean number of pills decreasing from 7.9 pills/day before and 3.7 pills/day after mLPV/r (p<0.001), there were no differences over time in adherence rates by pill count and proportion of children with poor adherence (all p>0.05). Our study did not demonstrate improvement of QOL scores and adherence rates by pill count in pretreated HIV-infected children after simplification of the antiretroviral regimen to lopinavir/ritonavir monotherapy.

Impact of antiretroviral therapy on quality of life in HIV-infected Southeast Asian children in the PREDICT study

Quality of life (QOL) is an important antiretroviral treatment (ART) outcome. We compared QOL among 299 Thai and Cambodian children ages 1-12 years-old, CD4 15-24% randomized to early (ART at week 0, N=149) versus deferred groups (ART when at CD4 <15%, N=150) and also compared with QOL data from age-matched healthy controls (N=275). Primary caregivers completed PACTG QOL questionnaires at week 0 and every 24 weeks until 144 weeks. Children were enrolled during March 2006 to September 2008. Mean (SD) age of children was 6.3 (2.8) years, 58% were female, 60% were Thai, %CDC N:A:B:C was 2:62:36:0%. During 144 weeks, all children in the early-group and 69 (46%) of deferred-group children started ART. There was no significant difference of QOL scores between treatment groups at baseline (all p>0.05) and at week 144 (all p>0.05). By multivariate analysis, the early-group had higher QOL score changes in five domains, including health perception (p=0.04), physical resilience (p=0.02), psychosocial well-being (p=0.04), social and role functioning (p<0.01), and symptoms (p=0.01) compared to the deferred group. QOL of HIV-infected children in both groups were lower than healthy control in all 7 domains at baseline (all p<0.05) and 5 of 7 domains at weeks 144 (p<0.01). In conclusion, no significant difference of QOL scores between treatment groups. Early ART commencement associated with greater increase of QOL scores over 144 weeks. QOL scores in HIV-infected children were lower than healthy controls.

Regional brain gray and white matter changes in perinatally HIV-infected adolescents

Despite the success of antiretroviral therapy (ART), perinatally infected HIV remains a major health problem worldwide. Although advance neuroimaging studies have investigated structural brain changes in HIV-infected adults, regional gray matter (GM) and white matter (WM) volume changes have not been reported in perinatally HIV-infected adolescents and young adults. In this cross-sectional study, we investigated regional GM and WM changes in 16 HIV-infected youths receiving ART (age 17.0 ± 2.9 years) compared with age-matched 14 healthy controls (age 16.3 ± 2.3 years) using magnetic resonance imaging (MRI)-based high-resolution T1-weighted images with voxel based morphometry (VBM) analyses. White matter atrophy appeared in perinatally HIV-infected youths in brain areas including the bilateral posterior corpus callosum (CC), bilateral external capsule, bilateral ventral temporal WM, mid cerebral peduncles, and basal pons over controls. Gray matter volume increase was observed in HIV-infected youths for several regions including the left superior frontal gyrus, inferior occipital gyrus, gyrus rectus, right mid cingulum, parahippocampal gyrus, bilateral inferior temporal gyrus, and middle temporal gyrus compared with controls. Global WM and GM volumes did not differ significantly between groups. These results indicate WM injury in perinatally HIV-infected youths, but the interpretation of the GM results, which appeared as increased regional volumes, is not clear. Further longitudinal studies are needed to clarify if our results represent active ongoing brain infection or toxicity from HIV treatment resulting in neuronal cell swelling and regional increased GM volume. Our findings suggest that assessment of regional GM and WM volume changes, based on VBM procedures, may be an additional measure to assess brain integrity in HIV-infected youths and to evaluate success of current ART therapy for efficacy in the brain.

Social ecological predictors of longitudinal HIV treatment adherence in youth with perinatally acquired HIV

OBJECTIVE

To apply a social ecological model to explore the psychosocial factors prospectively associated with longitudinal adherence to antiretroviral treatment in youth perinatally infected with HIV.

METHODS

Randomly selected youth, age 8 to <19 years old, completed cognitive testing and psychosocial questionnaires at baseline as part of a multisite protocol (N = 138). A validated caregiver-report measure of adherence was completed at baseline and 24 and 48 weeks after baseline.

RESULTS

In multivariate analysis, youth awareness of HIV status, caregiver not fully responsible for medications, low caregiver well-being, adolescent perceptions of poor caregiver-youth relations, caregiver perceptions of low social support, and African American ethnicity were associated with nonadherence over 48 weeks.

CONCLUSIONS

Interventions focusing on caregivers and their interactions with the individual youth and extrafamilial system should be prioritized for prevention and treatment efforts to address nonadherence during the transition into adolescents.

How can we simplify antiretroviral therapy in children?

PURPOSE OF REVIEW

The aim of this article is to present approaches towards simplifying pediatric antiretroviral therapy in order to improve access to care, coverage of HIV-positive children, and support adherence to treatment.

RECENT FINDINGS

Barriers to rapid and effective global scale-up of pediatric antiretroviral therapy include the narrow range of available pediatric antiretrovirals, complicated dosing schedules, and social and economic instability of the family caused by poverty, stigma, and death. Healthcare providers can simplify antiretroviral therapy delivery by promoting the development and use of pediatric fixed dose combinations and scored adult antiretrovirals, using weight-band dosing tables to prescribe antiretrovirals, and identifying less complex regimens. Caretakers would benefit from active counseling to facilitate more open communication with their children about adherence and disclosure. Children can develop long-term coping strategies through learning life skills that build confidence and improve decision-making. Whenever possible, antiretroviral therapy programs should provide access to free antiretrovirals, identify funds to cover transportation costs, and refer families to available community support programs.

SUMMARY

Interventions to simplify the administration of antiretroviral therapy need to address not only how antiretrovirals are prescribed and formulated, but the relationships of HIV-positive children with their families and communities as well.

Measuring health-related quality of life of HIV-positive adolescents in resource-constrained settings

BACKGROUND AND OBJECTIVES

Access to antiretroviral treatment among adolescents living with HIV (ALH) is increasing. Health-related quality of life (HRQOL) is relevant for monitoring the impact of the disease on both well-being and treatment outcomes. However, adequate screening tools to assess HRQOL in low-resource settings are scarce. This study aims to fill this research gap, by 1) assessing the psychometric properties and reliability of an Eastern African English version of a European HRQOL scale for adolescents (KIDSCREEN) and 2) determining which version of the KIDSCREEN (52-, 27- and 10-item version) is most suitable for low-resource settings.

METHODS

The KIDSCREEN was translated into Eastern African English, Luganda (Uganda) and Dholuo (Kenya) according to standard procedures. The reconciled version was administered in 2011 to ALH aged 13-17 in Kenya (n = 283) and Uganda (n = 299). All three KIDSCREEN versions were fitted to the data with confirmatory factor analysis (CFA). After comparison, the most suitable version was adapted based on the CFA outcomes utilizing the results of previous formative research. In order to develop a general HRQOL factor, a second-order measurement model was fitted to the data.

RESULTS

The CFA results showed that without adjustments, the KIDSCREEN cannot be used for measuring the HRQOL of HIV-positive adolescents. After comparison, the most suitable version for low-resource settings--the 27-item version--was adapted further. The introduction of a negative wording factor was required for the Dholuo model. The Dholuo (CFI: 0.93; RMSEA: 0.039) and the Luganda model (CFI: 0.90; RMSEA: 0.052) showed a good fit. All cronbach's alphas of the factors were 0.70 or above. The alpha value of the Dholuo and Lugandan HRQOL second-order factor was respectively 0.84 and 0.87.

CONCLUSIONS

The study showed that the adapted KIDSCREEN-27 is an adequate tool for measuring HRQOL in low-resource settings with high HIV prevalence.

Cognitive, academic, and behavioral correlates of medication adherence in children and adolescents with perinatally acquired HIV infection

OBJECTIVE

Medication adherence is critical to the success of antiretroviral therapies for children and youth with perinatally acquired HIV. Factors that influence successful transition of medication responsibility from caregivers to youth are poorly understood. The purpose of this study was to evaluate the relationship of medication adherence with demographic, cognitive, academic, and behavioral characteristics.

METHODS

Randomly selected youth, N = 151, aged 8 to 18 years, completed cognitive and academic measures, and they and their caregivers completed questionnaires assessing behavior and emotional well-being. An announced pill count and questionnaires completed by youth and their caregivers were used to evaluate adherence.

RESULTS

Of 151 participants, 100 completed all adherence measures. Adherence rates varied by assessment method. Nonadherence (<90%) by pill count was associated with older child age, greater youth responsibility for medications, and other demographic and medication regimen variables. Verbal impairment predicted better self-reported adherence and reading problems predicted better self- and caregiver-reported adherence. Youth-reported locus of control was associated with pill count nonadherence, and poor relationships with parents were associated with youth-reported nonadherence.

CONCLUSIONS

Consideration of youth cognitive or academic status may be helpful in evaluating medication adherence in patients with perinatally acquired HIV infection, particularly when using self- or caregiver reports to assess adherence. Vigilance for adherence problems is indicated when youth are older, responsible for medications, report poor caregiver relationships, and/or sense a lack of control over their lives.

Fracture risk by HIV infection status in perinatally HIV-exposed children

The objective of this study was to examine the incidence of fractures in HIV-infected children and comparable HIV-exposed, uninfected (HEU) children in a multicenter, prospective cohort study (PACTG 219/219C) in the United States. The main outcome was first fracture during the risk period. Nine fractures occurred in 7 of 1326 HIV-infected and 2 of 649 HEU children, corresponding to incidence rates of 1.2 per 1000 person-years and 1.1 per 1000 person-years, respectively. The incidence rate ratio was 1.1 (95% CI 0.2, 5.5). There was no evidence of a substantially increased risk of fracture in HIV-infected compared to HEU children.

Anaerobic power and muscle strength in human immunodeficiency virus-positive preadolescents

OBJECTIVE

To determine the anaerobic power and muscle strength of preadolescents with human immunodeficiency virus (HIV).

DESIGN

Cross-sectional design.

SETTING

Human performance laboratory at the University District Hospital at the Puerto Rico Medical Center.

PARTICIPANTS

Fifteen preadolescents (8 girls and 7 boys) with a classification of HIV A and B attending an investigational treatment program at the University Pediatric Hospital. Fifteen seronegative control subjects matched by age and gender also were included.

MAIN OUTCOME MEASURES

The power of the lower extremities was measured with use of the Wingate Anaerobic Power Test on a MONARK cycle ergometer (mean power in watts). Local muscle strength of the dominant knee extensors (peak torque/body weight × 100) was tested with an isokinetic dynamometer set at 60 deg/s. Statistical analysis was performed with the Wilcoxon signed-rank test, and statistical significance was accepted at an α level of <.05.

RESULTS

No significant differences between the control group and study group were detected on muscle strength testing. The study group presented a lower anaerobic power (mean power) compared with control subjects (P = .04).

CONCLUSIONS

This exploratory study suggests that HIV-infected preadolescents present lower anaerobic power compared with uninfected control subjects. Our findings of impaired anaerobic capacity can have clinical implications in this population because most of the activities of daily living, such as play, leisure, and sport activities, are short term and high intensity (anaerobic) in nature.

Role of non-nucleoside reverse transcriptase inhibitors in treating HIV-infected children

The first-generation non-nucleoside reverse transcriptase inhibitors (NNRTIs), efavirenz and nevirapine, fulfil key roles in antiretroviral therapy for HIV-infected paediatric patients, from lowering the incidence of mother-to-child transmission during pregnancy and birth to treatment throughout childhood and adolescence. Both agents have established efficacy, safety and tolerability profiles, and also offer advantages over other classes of therapy in terms of regimen simplicity and availability across different treatment settings. Although the role of NNRTIs in paediatric treatment strategies is largely determined by experience in adult patients, results of the recent phase II/III PENPACT-1 trial in infants and children aged between 30 days and 18 years have shown that there are no significant differences in 4-year virological, immunological or clinical outcomes between NNRTIs and protease inhibitors as first- and second-line agents. However, results from the IMPAACT P1060 study (cohort 2), conducted in resource-limited settings, showed that infants under 36 months unexposed to NNRTIs were significantly more likely to fail treatment when started on a nevirapine-based regimen than those on a lopinavir/ritonavir-based regimen. Unfortunately, the use of efavirenz and nevirapine in children can be limited by rapid development of high-level resistance to one or both agents, which may reduce the availability of viable treatment options, particularly in resource-limited settings. Several therapeutic strategies addressing this issue are currently under investigation, but a significant need for new NNRTI-based treatment options remains. The more recently approved NNRTI, etravirine, has demonstrated efficacy and safety benefits in HIV-1-infected, NNRTI-resistant adult patients, with a higher genetic barrier to the development of resistance relative to the first-generation NNRTIs. Another NNRTI, rilpivirine (TMC278), is approved for use in HIV-1-infected, treatment-naïve adult patients and has demonstrated an improved tolerability profile compared with efavirenz. Although available data on etravirine in children are currently limited, ongoing trials will provide important information on the potential for their use in novel paediatric treatment strategies. This review examines the role of efavirenz and nevirapine in paediatric antiretroviral therapy in children within different treatment settings. In addition, this review also outlines available clinical data on etravirine and rilpivirine in the context of how these antiretrovirals may address some of the limitations of efavirenz and nevirapine in paediatric patients.

Health Related Quality of Life Assessment questionnaire for children aged 5 to 11 years with HIV/AIDS: cross-cultural adaptation for the Portuguese language

The objective of this study is to describe preliminary results from the cross-cultural adaptation of the Quality of Life Assessment Questionnaire, used to measure health related quality of life (HRQL) in Brazilian children aged between 5 and 11 with HIV/AIDS. The cross-cultural model evaluated the Concept, Item, Semantic and Measurement Equivalences (internal consistency and intra-observer reliability). Evaluation of the conceptual, item, semantic equivalences showed that the Portuguese version is pertinent for the Brazilian context. Four of seven domains showed internal consistency above 0.70 (α: 0.76-0.90) and five of seven revealed intra-observer reliability (ricc: 0.41-0.70). This first Portuguese version of the HRQL questionnaire can be understood as a valuable tool for assessing children's HRQL, but further studies with large samples and more robust analyses are recommended before use in the Brazilian context.

Poor quality of life among untreated Thai and Cambodian children without severe HIV symptoms

There are limited data on quality of life (QOL) 1 in untreated HIV-infected children who do not have severe HIV symptoms. Moreover, such data do not exist for Asian children. Poor QOL could be a factor in deciding if antiretroviral therapy (ART) should be initiated. Thai and Cambodian children (n=294), aged 1-11 years, naïve to ART, with mild to moderate HIV symptoms and CD4 15-24% were enrolled. Their caregivers completed the Pediatric AIDS Clinical Trials Group QOL questionnaire prior to ART commencement. Six QOL domains were assessed using transformed scores that ranged from 0 to 100. Higher QOL scores indicated better health. Mean age was 6.1 (SD 2.8) years, mean CD4 was 723 (SD 369) cells/mm(3), 57% was female, and%CDC N:A:B was 2:63:35%. One-third knew their HIV diagnosis. Mean (SD) scores were 69.9 (17.6) for health perception, 64.5 (16.2) for physical resilience, 84.2 (15.6) for physical functioning, 77.9 (16.3) for psychosocial well-being, 74.7 (28.7) for social and role functioning, 90.0 (12.1) for health care utilization, and 87.4 (11.3) for symptoms domains. Children with CD4 counts above the 2008 World Health Organization (WHO) ART-initiation criteria (n=53) had higher scores in health perception and health care utilization than those with lower CD4 values. Younger children had poorer QOL than older children despite having similar mean CD4%. In conclusion, untreated Asian children without severe HIV symptoms had relatively low QOL scores compared to published reports in Western countries. Therapy initiation criteria by the WHO identified children with lower QOL scores to start ART; however, children who did not fit ART-initiation criteria and those who were younger also displayed poor QOL. QOL assessment should be considered in untreated children to inform decisions about when to initiate ART.

Health-related quality of life in children and adolescents with sickle cell disease

OBJECTIVE

To assess health-related quality of life (HRQOL) in children and adolescents with sickle cell disease (SCD).

DESIGN, SETTING, AND PARTICIPANTS

The PedsQL 4.0 Generic Scales, a multidimensional self-report instrument that has been shown to be valid and reliable for use in children and adolescents with chronic illness, consists of 23 items that assess physical, emotional, social, and school functioning. Questionnaires were administered to 124 children and adolescents (ages 8 to 18 years, child self-report) with SCD (100 sickle cell anemia, 24 sickle β zero thalassemia) and their parents (parent-proxy report). Summary scores for children's and parents' ratings of overall HRQOL and psychosocial health and subscale scores for physical, emotional, social, and school functioning were compared with published data for healthy children. Both summary and subscale scores for children with SCD also were compared with those of their parents.

RESULTS

Children with SCD and their parents rated overall HRQOL and all subdomains of HRQOL lower than did healthy children and their parents (P < .001). Children with SCD rated their own HRQOL significantly better than their parents did for overall HRQOL and all subdomains (P < .001) except emotional functioning (P = .06).

CONCLUSIONS

Children with SCD and their parents perceived overall HRQOL and all HRQOL subdomains to be lower than scores reported in healthy children. Therefore, successful therapeutic efforts to improve HRQOL could represent important advances in the health of children with SCD.

Quality of life and related factors among HIV-positive spouses from serodiscordant couples under antiretroviral therapy in Henan Province, China

OBJECTIVE

To describe the quality of life and related factors in HIV-positive spouses undergoing ART from discordant couples.

METHODS

A cross-sectional study was conducted among 1,009 HIV-positive spouses from serodiscordant couples in Zhumadian, Henan Province, between October 1, 2008 and March 31, 2009. HIV-positive spouses were interviewed by local health professionals. Quality of life was evaluated by WHOQOL (Chinese Version). A multiple linear regression model was used to analyze the related factors.

RESULTS

The majority of subjects were female (56.39%), had received a high school education (44%), were of Han ethnicity (98.41%), and were farmers (90.09%); the median time period of receiving ART was 3.92 years. The physical, psychological, social, and environmental QOL scores of the subjects were 12.91±1.95, 12.35±1.80, 13.96±2.43, and 12.45±1.91 respectively. The multiple linear regression model identified the physical domain related factors to be CD4 count, educational level, and occupation; psychological domain related factors include age, educational level, and reported STD symptom; social domain related factors included education level; and environmental domain related factors included education level, reported STD symptoms, and occupation.

CONCLUSION

Being younger, a farmer, having a lower level of education, a reported STD symptom, or lower CD4 count, could decrease one's quality of life, suggesting that the use of blanket ART programs alone may not necessarily improve quality of life. Subjects received lower scores in the psychological domain, suggesting that psychological intervention may also need to be strengthened.

Medication adherence in children and adolescents with HIV infection: associations with behavioral impairment

The impact of behavioral functioning on medication adherence in children with perinatally acquired HIV infection is not well-explored, but has important implications for intervention. This report addresses the relationship between behavioral functioning and child self-report or caregiver report of medication adherence among children and adolescents enrolled in Pediatric AIDS Clinical Trials Group Protocol 219C (conducted 2000-2007). A total of 1134 participants, aged 3-17 years, received a behavioral evaluation and adherence assessment. Complete adherence was defined as taking 100% of prescribed antiretroviral medications during three days preceding the study visit. Multivariable logistic regression models were used to evaluate associations between adherence and behavioral functioning, adjusting for potential confounders, including demographic, psychosocial, and health factors. Children demonstrated higher than expected rates of behavioral impairment (≈7% expected with T > 65) in the areas of conduct problems (14%, z = 7.0, p < 0.001), learning problems (22%, z = 12.2, p < 0.001), somatic complaints (22%, z = 12.6, p < 0.001), impulsivity-hyperactivity (20%, z = 11.1, p < 0.001), and hyperactivity (19%, z = 10.6, p < 0.001). Children with behavioral impairment in one or more areas had significantly increased odds of nonadherence [adjusted odds ratio (aOR) = 1.49, p = 0.04]. The odds of nonadherence were significantly higher for those with conduct problems and general hyperactivity (aOR = 2.03, p = 0.005 and aOR = 1.68, p = 0.02, respectively). Psychosocial and health factors, such as recent stressful life events and higher HIV RNA levels, were also associated with nonadherence. Knowledge of behavioral, health, and social influences affecting the child and family should guide the development of appropriate, evidence-based interventions for medication adherence.

The Changing Horizons of U.S. Families Living With Pediatric HIV

Although HIV is considered a chronic pediatric illness that is on the wane in the United States, challenges remain for those affected. The purpose of this longitudinal qualitative study was to examine the phenomenon of raising an HIV-positive child in the United States from the parental perspective. This study incorporated a longitudinal, phenomenological approach. The purposive sample included parents and guardians from 10 families from the northeast region of the United States with children diagnosed with asymptomatic HIV infection at the study onset. The researcher conducted in-depth interviews with the parents over a 7-year period. The common themes identified included: balancing normalcy with uncertainty, facing the multifaceted dilemmas associated with disclosure, and addressing the evolving medication and treatment challenges. The findings of this study can enhance the understanding of nurses and other health care professionals to improve policies, standards of care, and interventions for children and families living with pediatric HIV infection.

Post-HAART outcomes in pediatric populations: comparison of resource-limited and developed countries

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.

Long-term follow-up outcomes of perinatally HIV-infected adolescents: infection control but school failure

Perinatally human immunodeficiency virus (HIV)-infected children are fighting acquired immune deficiency syndrome (AIDS) and becoming adolescents. The objective of this study was to examine long-term outcomes among perinatally HIV-1-infected adolescents. Cross-sectional clinical and laboratory data were collected for 49 perinatally HIV-infected adolescents followed at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP's) Hospital from 1987 to 2007. The mean age of these adolescents was 12.5 years, the majority were female (73.5%) with a mean follow-up duration of 9.0 years, 71.4% of adolescents had no signs of HIV infection, 81.6% had normal CD4(+) lymphocyte count, and 53.1% had undetectable HIV viral load. HIV disclosure to the adolescent was reported in 31 (63.3%) participants. The majority were in school (89.8%) but failure and drop-out were reported by 51% and 28.6% of the subjects, respectively. All five domains of quality of life (QOL) measured revealed high scores. The majority of long-term adolescent survivors showed HIV-infection control and high scores of QOL, but with problems in schooling functioning that need early detection and intervention.

Quality of life and psychosocial functioning of HIV infected children

OBJECTIVE

To assess the quality of life (QOL) and the psychosocial problems of HIV infected children.

METHODS

The present study was a comparative, cross-sectional survey conducted in the clinic of a tertiary care hospital in north India from July-December 2007. Children suffering from cystic fibrosis (CF) were chosen as a comparison group. Children (3) 6 yr of age with HIV infection or Cystic Fibrosis, with no acute illness at the time of survey were included in the study. Quality of life of the enrolled children was assessed by using the Pediatric Quality of Life Inventory (PedsQL). Pediatric Symptom Checklist (PSC) was used for assessing the psychosocial problems in the enrolled children.

RESULTS

Forty one HIV infected and 30 children with cystic fibrosis were enrolled. According to child self -report in the PedsQL 4.0, the difference of perceived physical health status between the two study groups was statistically significant (p=0.04), with HIV infected children demonstrating a better QOL in this domain. A significantly greater number of children with cystic fibrosis (8/30 or 26.67%) suffered from psychosocial problems as compared to HIV children (3/41 or 7.32%) [p=0.026].

CONCLUSIONS

The quality of life and psychosocial functioning is reasonably good in children with HIV infection. Thus, we should strive to maintain and optimize the overall quality of life of these children so that they can have a productive and meaningful future.

Growing up with HIV: children, adolescents, and young adults with perinatally acquired HIV infection

Tremendous success in the prevention and treatment of pediatric HIV in high-resource countries has changed the face of the epidemic. A perinatally HIV-infected child now faces a chronic disease rather than a progressive, fatal one. However, these successes pose new challenges as perinatally HIV-infected youth survive into adulthood. These include maintaining adherence to long-term, likely life-long therapy; selecting successive antiretroviral drug regimens, given the limited availability of pediatric formulations and the lack of pharmacokinetic and safety data in children; and overcoming extensive drug resistance in multi-drug-experienced children. Pediatric HIV care now focuses on morbidity related to long-term HIV infection and its treatment. Survival into adulthood of perinatally HIV-infected youth in high-resource countries encourages expansion of pediatric treatment programs in low-resource countries, where most HIV-infected children live, and provides important lessons about how the epidemic changes with increasing access to antiretroviral therapy for children.

The use of second-generation antipsychotics and the changes in physical growth in children and adolescents with perinatally acquired HIV

Second-generation antipsychotics (SGAs) are increasingly prescribed to treat psychiatric symptoms in pediatric patients infected with HIV. We examined the relationship between prescribed SGAs and physical growth in a cohort of youth with perinatally acquired HIV-1 infection. Pediatric AIDS Clinical Trials Group (PACTG), Protocol 219C (P219C), a multicenter, longitudinal observational study of children and adolescents perinatally exposed to HIV, was conducted from September 2000 until May 2007. The analysis included P219C participants who were perinatally HIV-infected, 3-18 years old, prescribed first SGA for at least 1 month, and had available baseline data prior to starting first SGA. Each participant prescribed an SGA was matched (based on gender, age, Tanner stage, baseline body mass index [BMI] z score) with 1-3 controls without antipsychotic prescriptions. The main outcomes were short-term (approximately 6 months) and long-term (approximately 2 years) changes in BMI z scores from baseline. There were 236 participants in the short-term and 198 in the long-term analysis. In linear regression models, youth with SGA prescriptions had increased BMI z scores relative to youth without antipsychotic prescriptions, for all SGAs (short-term increase = 0.192, p = 0.003; long-term increase = 0.350, p < 0.001), and for risperidone alone (short-term = 0.239, p = 0.002; long-term = 0.360, p = 0.001). Participants receiving both protease inhibitors (PIs) and SGAs showed especially large increases. These findings suggest that growth should be carefully monitored in youth with perinatally acquired HIV who are prescribed SGAs. Future research should investigate the interaction between PIs and SGAs in children and adolescents with perinatally acquired HIV infection.

Adolescents and HIV: prevention and clinical care

The incidence of HIV infection has increased to alarming proportions among minority youth, in particular among young men who have sex with men and among teenage girls. The unique socioeconomic, behavioral, and emotional vulnerability of adolescents for sexually transmitted diseases, including HIV, requires early identification of HIV infection for linkage to care. Differences in the clinical and psychosocial presentations of youth with perinatally versus behavioral acquired HIV infection are important and influence the acceptance of illness, self-efficacy, and antiretroviral treatment adherence. The ideal multidisciplinary team approach of culturally sensitive services for youth integrates clinical care, psychosocial and peer support interventions, transition planning, primary and secondary prevention, as well as comprehensive reproductive adolescent health services.

Impact of disclosure of HIV infection on health-related quality of life among children and adolescents with HIV infection

BACKGROUND

Little is known concerning the impact of HIV status disclosure on quality of life, leaving clinicians and families to rely on research of children with other terminal illnesses.

OBJECTIVES

The purpose of this work was to examine the impact of HIV disclosure on pediatric quality of life and to describe the distribution of age at disclosure in a perinatally infected pediatric population. METHODS. A longitudinal analysis was conducted of perinatally HIV-infected youth >/=5 years of age enrolled in a prospective cohort study, Pediatric AIDS Clinical Trials Group 219C, with >/=1 study visit before and after HIV disclosure. Age-specific quality-of-life instruments were completed by primary caregivers at routine study visits. The distribution of age at disclosure was summarized. Six quality-of-life domains were assessed, including general health perception, symptom distress, psychological status, health care utilization, physical functioning, and social/role functioning. For each domain, mixed-effects models were fit to estimate the effect of disclosure on quality of life.

RESULTS

A total of 395 children with 2423 study visits were analyzed (1317 predisclosure visits and 1106 postdisclosure visits). The median age at disclosure was estimated to be 11 years. Older age at disclosure was associated with earlier year of birth. Mean domain scores were not significantly different at the last undisclosed visit compared with the first disclosed visit, with the exception of general health perception. When all of the visits were considered, 5 of 6 mean domain scores were lower after disclosure, although the differences were not significant. In mixed-effects models, disclosure did not significantly impact quality of life for any domain.

CONCLUSIONS

Age at disclosure decreased significantly over time. There were no statistically significant differences between predisclosure and postdisclosure quality of life; therefore, disclosure should be encouraged at an appropriate time.

Assessment of adherence to antiretroviral therapy in perinatally HIV-infected children and youth using self-report measures and pill count

BACKGROUND

Parent/caregiver or child/youth self-report and pill counts are commonly used methods for assessing adherence to antiretroviral therapy among children and youth with HIV. The purpose of this study was to compare these different methods with one another and with viral load.

METHODS

Randomly selected parent/caregiver and child/youth dyads were interviewed using several adherence self-report measures and an announced pill count was performed. Adherence assessment methods were compared with one another and their relative validity was assessed by comparison with the child's viral load close to the time of the interview or pill count, adjusting for primary caregiver, child age, and child disclosure of the diagnosis.

RESULTS

There were 151 evaluable participants. Adherence rate by pill count was >or=90% in 52% of participants, was significantly associated with log(RNA) viral load (p = .032), and had significant agreement with viral load <400 copies/mL. However, pill count data were incomplete for 26% of participants. With similar proportions considered adherent, a variety of self-report adherence assessment methods also were associated with log(RNA) viral load including: "no dose missed within the past 1 month" (p = .054 child/youth interview, p = .004 parent/caregiver interview), and no barrier to adherence identified (p = .085 child/youth interview, p = .015 parent/caregiver interview). Within-rater and inter-rater agreement was high among self-report methods. Three day recall of missed doses was not associated with viral load.

CONCLUSION

Findings demonstrate the validity of adherence assessment strategies that allow the parent/caregiver or child/youth to report on adherence over a longer period of time and to identify adherence barriers. Adherence assessed by announced pill count was robustly associated with viral load, but there was incomplete data for many participants.
