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

Postintensive care syndrome family: A comprehensive review

Families of critically ill patients are predisposed to tremendous burdens when their relatives are admitted to the intensive care unit (ICU). Postintensive care syndrome family (PICS-F) can be described as a devastated life, encompassing psychological, physical, and socioeconomical burdens that begin with the emotional impact experienced by the family when the patient is admitted to the ICU. PICS-F was primarily proposed as a clinically significant psychological impairment, but it needs to be extended beyond the psychological impairment of the family to include physical and socioeconomical impairments in the future. The prevalence of physiological problems including depression, anxiety and post-traumatic syndrome is 20-40%, and that of non-physiological problems including fatigue is 15% at 6 months after the ICU stay. Assessment of PICS-F was frequently conducted at 3- or 6-month points, although the beginning of the evaluation was based on different assessment points among each of the studies. Families of ICU patients need to be given and understand accurate information, such as the patient's diagnosis, planned care, and prognosis. Prevention of PICS-F requires a continuous bundle of multifaceted and/or multidisciplinary interventions including providing a family information leaflet, ICU diary, communication facilitators, supportive grief care, and follow-up, for the patient and families from during the ICU stay to after discharge from the ICU. This is the first comprehensive review of PICS-F to address the concept, risk factors, assessment tools, prevalence, and management to prevent PICS-F to facilitate acute care physicians' understanding of PICS-F.

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.

Machine-learning classification of neurocognitive performance in children with perinatal HIV initiating de novo antiretroviral therapy

OBJECTIVE

To develop a predictive model of neurocognitive trajectories in children with perinatal HIV (pHIV).

DESIGN

Machine learning analysis of baseline and longitudinal predictors derived from clinical measures utilized in pediatric HIV.

METHODS

Two hundred and eighty-five children (ages 2-14 years at baseline; Mage = 6.4 years) with pHIV in Southeast Asia underwent neurocognitive assessment at study enrollment and twice annually thereafter for an average of 5.4 years. Neurocognitive slopes were modeled to establish two subgroups [above (n = 145) and below average (n = 140) trajectories). Gradient-boosted multivariate regressions (GBM) with five-fold cross validation were conducted to examine baseline (pre-ART) and longitudinal predictive features derived from demographic, HIV disease, immune, mental health, and physical health indices (i.e. complete blood count [CBC]).

RESULTS

The baseline GBM established a classifier of neurocognitive group designation with an average AUC of 79% built from HIV disease severity and immune markers. GBM analysis of longitudinal predictors with and without interactions improved the average AUC to 87 and 90%, respectively. Mental health problems and hematocrit levels also emerged as salient features in the longitudinal models, with novel interactions between mental health problems and both CD4 cell count and hematocrit levels. Average AUCs derived from each GBM model were higher than results obtained using logistic regression.

CONCLUSION

Our findings support the feasibility of machine learning to identify children with pHIV at risk for suboptimal neurocognitive development. Results also suggest that interactions between HIV disease and mental health problems are early antecedents to neurocognitive difficulties in later childhood among youth with pHIV.

Effects of a High Protein Food Supplement on Physical Activity, Motor Performance and Health Related Quality of Life of HIV Infected Botswana Children on Anti-Retroviral Therapy (ART)

Objective

Despite existing evidence about the benefits of nutrition, physical activity (PA) and sport to the overall health and wellbeing of children, knowledge gaps remain on this relationship in children living with chronic conditions like HIV/AIDS. Such knowledge should inform context specific programs that could enhance the quality of life of children. The purpose of this study was to examine the effects of integrating a nutrition intervention (culturally tailored food supplement) into antiretroviral therapy (ART) on psychosocial outcomes and physical activity among HIV-positive children in Botswana.

Method

201 HIV-positive children (6–15 years; M = 9.44, SD = 2.40) were recruited and randomly assigned (stratified by age and gender) to two groups. The intervention group (n = 97) received a high protein (bean-sorghum plus micronutrients) food supplement, while the control group (n = 104) received a sorghum plus micronutrients supplement. Participants were followed over 12 months. Anthropometric measures, PA, motor performance, and health related quality of life (HRQL) were collected at baseline, 6 and 12 months.

Results

Mixed repeated-measures ANOVA revealed a significant time effect of the food supplement on target variables except body fat percentage, speed, and school functioning. Time × treatment interaction was found for physical functioning, psychosocial functioning and total quality of life score. Scores on physical functioning and total of quality life in the intervention group significantly increased from baseline to 6 months compared with the control group (p = 0.015).

Conclusion

A combination of ART and nutritional intervention had a positive effect on physical functioning and total quality of life of HIV-positive children in this study. There were also improvements to physical activity and motor performance tests over time. More research is needed on long term effects of nutrition and PA interventions on HRQL in children living with HIV.

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.

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.

The Methodological Challenges for the Estimation of Quality of Life in Children for Use in Economic Evaluation in Low-Income Countries

OBJECTIVES

The assessment of quality of life (QOL) in children has been underresearched in high- and low-income countries alike. This is partly due to practical and methodological challenges in characterizing and assessing children's QOL. This article explores these challenges and highlights considerations in developing age-specific instruments for children affected by HIV and other health conditions in Africa and other low-income settings.

METHODS

A literature search identified works that have 1) developed, 2) derived utilities for, or 3) applied QOL tools for use in economic evaluations of HIV interventions for children. We analyzed the existing tools specifically in terms of domains considered, variations in age bands, the recommended respondents, and the relevance of the tools to African and also other low-income country contexts.

RESULTS

Only limited QOL research has been conducted in low-income settings on either adults or children with HIV. A few studies have developed and applied tools for children (e.g., in Thailand, Brazil, and India), but none have been in Africa. The existing methodological literature is inconclusive on the appropriate width or depth by which to define pediatric QOL. The existing instruments include QOL domains such as "physical functioning," "emotional and cognitive functioning," "general behavior (social, school, home)," "health perception," "coping and adaptation," "pain and discomfort," "extended effects," "life perspective," and "autonomy."

CONCLUSIONS

QOL assessment in children presents a series of practical and methodological challenges. Its application in low-income settings requires careful consideration of a number of context-specific factors.
