Neuropsychiatric Function Improvement in Pediatric Patients with Phenylketonuria.

OBJECTIVE: To evaluate effects of sapropterin dihydrochloride on blood phenylalanine (Phe) and symptoms of neuropsychiatric impairment in children and adolescents with phenylketonuria (PKU). STUDY DESIGN: PKU subjects 8-17 years of age (n = 86) were randomized to double-blind treatment with sapropterin (n = 43) or placebo (n = 43) for 13 weeks, then all received open-label sapropterin therapy for an additional 13 weeks. Blood Phe and symptoms of inattention, hyperactivity/impulsivity (Attention-Deficit/Hyperactivity Disorder Rating Scale IV [ADHD RS-IV]), executive functioning (Behavior Rating Inventory of Executive Function), depression (Hamilton Rating Scale for Depression), and anxiety (Hamilton Rating Scale for Anxiety) were assessed. RESULTS: Following the 13-week randomization phase, the sapropterin and placebo groups had mean changes in blood Phe of -20.9% and +2.9%, respectively. Corresponding least square mean differences in ADHD RS-IV scores were significantly greater for the sapropterin vs the placebo group: Total (-3.2 points, P = .02), Inattention subscale (-1.8 points, P = .04), and Hyperactivity/Impulsivity subscale (-1.6 points, P = .02). Forest plots favored sapropterin treatment over placebo for all ADHD RS-IV and Behavior Rating Inventory of Executive Function indices. There were no significant differences in reported problems with attention or executive function between the 2 groups at baseline or at week 26 following the 13-week open-label treatment period. Anxiety and depression scores did not differ significantly between cohorts at any time. Sapropterin was well tolerated, with a favorable safety profile. CONCLUSIONS: Sapropterin reduced blood Phe and was associated with significant improvement in parent-reported symptoms of inattention, hyperactivity/impulsivity, and executive functioning in children and adolescents with PKU.

Management of early treated adolescents and young adults with phenylketonuria: Development of international consensus recommendations using a modified Delphi approach.

BACKGROUND: Early treated patients with phenylketonuria (PKU) often become lost to follow-up from adolescence onwards due to the historical focus of PKU care on the pediatric population and lack of programs facilitating the transition to adulthood. As a result, evidence on the management of adolescents and young adults with PKU is limited. METHODS: Two meetings were held with a multidisciplinary international panel of 25 experts in PKU and comorbidities frequently experienced by patients with PKU. Based on the outcomes of the first meeting, a set of statements were developed. During the second meeting, these statements were voted on for consensus generation (≥70% agreement), using a modified Delphi approach. RESULTS: A total of 37 consensus recommendations were developed across five areas that were deemed important in the management of adolescents and young adults with PKU: (1) general physical health, (2) mental health and neurocognitive functioning, (3) blood Phe target range, (4) PKU-specific challenges, and (5) transition to adult care. The consensus recommendations reflect the personal opinions and experiences from the participating experts supported with evidence when available. Overall, clinicians managing adolescents and young adults with PKU should be aware of the wide variety of PKU-associated comorbidities, initiating screening at an early age. In addition, management of adolescents/young adults should be a joint effort between the patient, clinical center, and parents/caregivers supporting adolescents with gradually gaining independent control of their disease during the transition to adulthood. CONCLUSIONS: A multidisciplinary international group of experts used a modified Delphi approach to develop a set of consensus recommendations with the aim of providing guidance and offering tools to clinics to aid with supporting adolescents and young adults with PKU.

Improved attention linked to sustained phenylalanine reduction in adults with early-treated phenylketonuria.

Pegvaliase is approved to reduce phenylalanine (Phe) levels for people with phenylketonuria (PKU). PRISM-1 (NCT01819727) and PRISM-2 (NCT01889862) data were analyzed to evaluate the relationship between Phe and inattention in adult participants with PKU. In the modified-intent-to-treat population (N = 156), baseline mean (SE) plasma Phe was 1263 (29) µmol/L and the Attention Deficit Hyperactivity Disorder Rating Scale-IV Inattentive (IA) symptoms score was 9.8 (0.5). Mean (SE) IA scores fell 9.0 (1.1) in Quartile 1 (Phe reduction between 1166 and 2229 µmol/L) versus 4.3 (0.7) in Quartile 4 (Phe reduction of 139 µmol/L to increase of 934 µmol/L), p = 0.004. Least squares mean (SE) change from baseline IA score was -7.9 (0.7) for participants with final Phe ≤ 360 µmol/L and -4.5 (0.7) for final Phe > 360 µmol/L, p < 0.001. In the inattention subgroup, IA scores fell 13.3 (1.5) in Quartile 1 (Phe reduction between 1288 and 2229 µmol/L) versus 6.2 (1.3) in Quartile 4 (Phe reduction of 247 to increase of 934 µmol/L), p = 0.009. Inattention symptoms improved among those whose Phe levels decreased, particularly those with high baseline IA scores. IA improvements were larger among participants with the greatest plasma Phe reductions, supporting this value as a therapeutic goal.

Neuropsychiatric comorbidities in adults with phenylketonuria: A retrospective cohort study.

Adults with phenylketonuria (PKU) may experience neurologic and psychiatric disorders, including intellectual disability, anxiety, depression, and neurocognitive dysfunction. Identifying the prevalence and prevalence ratios of these conditions will inform clinical treatment. This nested, case-controlled study used International Classification of Diseases, Ninth Revision (ICD-9) codes from the MarketScan® insurance claims databases from 2006 to 2012 and healthcare claims data for US-based employer and government-sponsored health plans. Prevalence and prevalence ratio calculations of neuropsychiatric comorbidities for adults (≥20years old) with PKU were compared with two groups [diabetes mellitus (DM) and general population (GP)] matched by age, gender, geographic location, and insurance type. Age cohorts (i.e., 20-29, 30-39, 40-49, 50-59, 60-69, and 70+years, and a combined subset of 20-39) were used to stratify data. The PKU cohort experienced significantly higher rates of several comorbid neurologic, psychiatric and developmental conditions. Compared to GP, PKU was associated with significantly higher prevalence for numerous neuropsychiatric conditions, most notably for intellectual disability (PR=7.9, 95% CI: 6.4-9.9), autism spectrum disorder (PR=6.1, 95% CI: 3.6-10.4), Tourette/tic disorders (PR=5.4, 95% CI: 2.1-14.1), and eating disorders (4.0, 95% CI: 3.2-5.0). Rates of fatigue/malaise, epilepsy/convulsions, sleep disturbance, personality disorders, phobias, psychosis, and migraines among those with PKU exceeded rates for the GP but were comparable to those with DM, with significantly lower rates of concomitant disorders occurring in younger, compared to older, adults with PKU. Lifelong monitoring and treatment of co-occurring neuropsychiatric conditions are important for effective PKU management.

Prevalence and Persistence of Varicella Antibodies in Previously Immunized Children and Youth With Perinatal HIV-1 Infection.

BACKGROUND: Two doses of live-attenuated varicella-zoster vaccine are recommended for human immunodeficiency virus 1 (HIV-1)-infected children with CD4% ≥ 15%. We determined the prevalence and persistence of antibody in immunized children with perinatal HIV (PHIV) and their association with number of vaccinations, combination antiretroviral therapy (cART), and HIV status. METHODS: The Adolescent Master Protocol is an observational study of children with PHIV and perinatally HIV-exposed but uninfected (PHEU) children conducted at 15 US sites. In a cross-sectional analysis, we tested participants' most recent stored sera for varicella antibody using whole-cell and glycoprotein enzyme-linked immunosorbent assay. Seropositivity predictors were identified using multivariable logistic regression models and C statistics. RESULTS: Samples were available for 432 children with PHIV and 221 PHEU children; 82% of children with PHIV and 97% of PHEU children were seropositive (P < .001). Seropositivity after 1 vaccine dose among children with PHIV and PHEU children was 100% at <3 years (both), 73% and 100% at 3-<7 years (P < .05), and 77% and 97% at ≥ 7 years (P < .01), respectively. Seropositivity among recipients of 2 vaccine doses was >94% at all intervals. Independent predictors of seropositivity among children with PHIV were receipt of 2 vaccine doses, receipt of 1 dose while on ≥ 3 months of cART, compared with none (adjusted odds ratio [aOR]: 14.0 and 2.8, respectively; P < .001 for overall dose effect), and in those vaccinated ≥ 3 years previously, duration of cART (aOR: 1.29 per year increase, P = .02). CONCLUSIONS: Humoral immune responses to varicella vaccine are best achieved when children with PHIV receive their first dose ≥ 3 months after cART initiation and maintained by completion of the 2-dose series and long-term cART use.

Antiretroviral Drug Resistance Among Children and Youth in the United States With Perinatal HIV.

Among 234 US youths with perinatal human immunodeficiency virus, 75% had antiretroviral resistance, substantially higher than that of the reference laboratory overall (36%-44%). Resistance to newer antiretrovirals and to all antiretrovirals in a class was uncommon. The only factor independently associated with future resistance was a higher peak viral load.

Newborn screening 50 years later: access issues faced by adults with PKU.

Fifty years after the implementation of universal newborn screening programs for phenylketonuria, the first disease identified through newborn screening and considered a success story of newborn screening, a cohort of adults with phenylketonuria treated from birth provides valuable information about effects of long-term treatment for inborn errors of metabolism in general, and phenylketonuria specifically. For phenylketonuria, newborn screening allows early implementation of the phenylalanine-restricted diet, eliminating the severe neurocognitive and neuromotor impairment associated with untreated phenylketonuria. However, executive function impairments and psychiatric problems are frequently reported even for those treated early and continuously with the phenylalanine-restricted diet alone. Moreover, a large percentage of adults with phenylketonuria are reported as lost to follow-up by metabolic clinics. While a group of experts identified by the National Institutes of Health convenes to update treatment guidelines for phenylketonuria, we explore individual patient, social, and economic factors preventing >70% of adult phenylketonuria patients in the United States from accessing treatment. As more conditions are identified through newborn screening, factors affecting access to treatment grow in importance, and we must continue to be vigilant in assessing and addressing factors that affect patient treatment outcomes and not just celebrate amelioration of the most severe manifestations of disease.

Quality of Life in Angelman Syndrome: A Caregivers' Survey.

BACKGROUND: Angelman syndrome (AS) is a genetic disorder, characterized by a cheerful disposition with bouts of laughter, developmental delay, speech impairment, ataxia, and seizures. Previous AS surveys have focused on the natural history, describing seizure types and response to anti-seizure medications. METHODS: A web-based survey was distributed to caregivers of individuals with AS to characterize motor function, cannabidiol (CBD) use, and factors affecting quality of life (QOL). RESULTS: Of a total of 183 individuals with AS (mean age 19.4 ± 13.4 years; 48.1% female), 72% had sleep problems, 80% had seizures, and 32% had one or more emergency department visits in the previous year. Eighty-eight percent were ambulatory (with or without assistance), and half experienced falls, 10.4% resulting in serious injury. Caregivers reported physical therapy, antiseizure medication, CBD, and clonidine as helpful. Inability to walk, falls/drops, sleep problems, and seizures significantly affected QOL (P < 0.002, <0.001, <0.001, P = 0.001, respectively). QOL was not influenced by gender, distance to the hospital, or genetic abnormality. CONCLUSIONS: These findings suggest that seizures are the tip of the iceberg. Use of a brief, valid screening tool can assist providers with identifying and addressing issues of primary concern to caregivers of individuals with AS.

Metabolic abnormalities and viral replication are associated with biomarkers of vascular dysfunction in HIV-infected children.

OBJECTIVES: HIV-infected children may be at risk for premature cardiovascular disease. We compared levels of biomarkers of vascular dysfunction in HIV-infected children (with and without hyperlipidaemia) with those in HIV-exposed, uninfected (HEU) children enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS), and determined factors associated with these biomarkers. METHODS: A prospective cohort study was carried out. Biomarkers of inflammation [C-reactive protein (CRP), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP1)], coagulant dysfunction (fibrinogen and P-selectin), endothelial dysfunction [soluble intracellular cell adhesion molecule-1 (sICAM), soluble vascular cell adhesion molecule-1 (sVCAM) and E-selectin], and metabolic dysfunction (adiponectin) were measured in 226 HIV-infected and 140 HEU children. Anthropometry, body composition, lipids, glucose, insulin, HIV disease severity, and antiretroviral therapy were recorded. RESULTS: The median ages of the children were 12.3 years in the HIV-infected group and 10.1 years in the HEU group. Body mass index (BMI) z-scores, waist and hip circumferences, and percentage body fat were lower in the HIV-infected children. Total and non-high-density lipoprotein (HDL) cholesterol and triglycerides were higher in HIV-infected children. HIV-infected children also had higher MCP-1, fibrinogen, sICAM and sVCAM levels. In multivariable analyses in the HIV-infected children alone, BMI z-score was associated with higher CRP and fibrinogen, but lower MCP-1 and sVCAM. Unfavourable lipid profiles were positively associated with IL-6, MCP-1, fibrinogen, and P- and E-selectin, whereas increased HIV viral load was associated with markers of inflammation (MCP-1 and CRP) and endothelial dysfunction (sICAM and sVCAM). CONCLUSIONS: HIV-infected children have higher levels of biomarkers of vascular dysfunction than do HEU children. Risk factors associated with higher biomarkers include unfavourable lipid levels and active HIV replication.

Intracranial localisation of ictal urinary urge epileptogenic zone to the non-dominant temporal lobe.

Ictal urinary urge is a rare symptom of focal epilepsy usually localising to the non-dominant hemisphere, specifically, the temporal lobe. Lateralisation in previously described cases has been established using scalp video-EEG monitoring or functional imaging. We report the case of a 19-year-old girl with refractory epilepsy and ictal urinary urge arising from the non-dominant temporal lobe, confirmed by invasive, subdural EEG monitoring. Since undergoing a temporal lobectomy two and a half years ago, the patient has not experienced ictal urinary urge. To our knowledge, this is the first report demonstrating localisation of ictal urinary urge epileptogenic zone to the non-dominant temporal lobe by invasive intracranial monitoring.

Sleep patterns in pediatric sickle cell disease.

BACKGROUND: Research examining sleep in children with sickle cell disease (SCD) has focused on the increased occurrence of specific sleep disorders (i.e., sleep-disordered breathing, hypoxemia, nocturnal enuresis), but no research exists describing general sleep behaviors of children with SCD. The purpose of the current study was to compare sleep patterns and sleep behaviors in children with SCD and healthy controls and examine the associations of demographic and disease factors with sleep in the SCD group. PROCEDURE: The Children's Sleep Habits Questionnaire was completed by parents of 4- to 10-year-old children with SCD (n = 54) and children attending well-care clinics in the same urban hospital (n = 52). Within the SCD group, demographic and disease factors [i.e., genotype, healthcare utilization, SCD complications, and socioeconomic status (SES)] were determined by medical chart review. RESULTS: Parents of children with SCD reported significantly more behaviors associated with night waking and sleep-disordered breathing than the control group. Within the SCD group, parasomnias were related to SES, enuresis, more severe genotypes, SCD complications, and healthcare utilization. Sleep-disordered breathing was also related to SES, enuresis, and SCD complications. CONCLUSIONS: Results indicate the importance of routinely assessing sleep in children with SCD as they are more likely to exhibit disrupted sleep than children with similar demographic backgrounds. Given significantly higher rates of parent reported sleep-disordered breathing and night waking in this population, it is important to consider interventions to minimize disruptions to overnight sleep and improve daytime functioning for quality of life in children with SCD.

Correlation between child and parental perceptions of health-related quality of life in epilepsy using the PedsQL.v4.0 measurement model.

Health-related quality-of-life measures in childhood epilepsy are typically limited to a particular functional domain, specific age group, parent proxy-report, or child self-report. Generic health-related quality-of-life instruments in paediatric epilepsy comparing child self-reports with simultaneous parent proxy-reports have not been previously investigated. A previously validated generic questionnaire, the Pediatric Quality of Life version 4 (PedsQL.v4.0), was used to prospectively assess parental and child perceptions of health-related quality of life in 100 children with epilepsy. The correlation between child and parental health-related quality-of-life perceptions across all domains was excellent (p < 0.001) and both were significantly lower than those for healthy controls (p < 0.001). Parents' perceptions of their children's health-related quality of life were lower than those for other chronic illnesses (p < 0.001), especially for refractory epilepsy. The presence of neurological or psychiatric comorbidities also had an adverse impact on health-related quality of life. The PedsQL.v4.0 measures health-related quality of life from both the parent's and child's perspective. Ease of use makes this instrument attractive for routine clinical use.

Executive function in phenylketonuria (PKU): Insights from the Behavior Rating Inventory of Executive Function (BRIEF) and a large sample of individuals with PKU.

OBJECTIVE: Previous research has documented executive function (EF) impairments in individuals with early treated phenylketonuria (ETPKU). It remains unclear, however, whether some aspects of EF may be more affected than others. A number of factors, including small sample sizes and variability in EF tasks, have likely contributed to past mixed findings. The present objective was to elucidate further the EF profile associated with ETPKU, particularly as it relates to report-based assessment of EF. METHOD: Data from 286 individuals (5-48 years of age) with ETPKU on the child and adult versions of the Behavior Rating Inventory of Executive Function (BRIEF), a well-established report-based assessment tool, were analyzed. RESULTS: The Working Memory scale showed the largest effect size in both young and older ETPKU samples, with 19% of children and 29% of adults scoring in the "abnormally elevated" range. In addition, EF impairment appeared more general (i.e., affecting more domains) in the adult sample as compared to the child sample. Exploratory analyses also suggested that the presence/absence of overall impairment on the BRIEF among our ETPKU participants could be predicted based on a small subset of items. A 10-item subset showed total classification accuracy values of 90% and above for both groups. CONCLUSIONS: Working memory represents an aspect of EF that appears to be particularly affected in individuals with ETPKU. Findings also provide preliminary support of the viability for the development and/or adoption of an abbreviated screening measure for EF difficulties in children and adults with ETPKU.

Severity of obstructive sleep apnea in children with sickle cell disease.

OBJECTIVE: To characterize polysomnographic (PSG) findings of children with sickle cell disease (SCD) suspected of having sleep disordered breathing (SDB). METHODS: Families of 100 consecutively referred children with SCD completed the Children's Sleep Habit Questionnaire during a routine visit to identify concerns regarding sleep habits and sleep behavior. Of these, 48 children were identified as displaying behaviors suspicious of SDB. Nineteen agreed to an overnight PSG. The results from the PSGs of the SCD with obstructive sleep apnea syndrome (OSAS) group (SCD-OSAS; group 1) were compared with the results of 10 age, sex, and ethnicity-matched patients identified as OSAS with no medical comorbidities (uncomplicated OSAS; group 2). RESULTS: SDB was identified in 79% of the SCD group. As compared with the uncomplicated OSAS group, the SCD with OSAS group displayed nocturnal desaturation with lower nadir values, of longer duration, with a 4-fold increased risk for oxygen desaturation below 85%, higher percentage of total sleep time with end-tidal carbon dioxide (ET CO2) values >50 mm Hg, with a 3.7-fold increased risk for spending more than 25% of total sleep time with ET CO2 more than 50 mm Hg and higher peak ET CO2 with a 7-fold increase for peak ET CO2 above 53 mm Hg. CONCLUSIONS: Children with SCD suspicious of SDB may have not only a higher incidence of OSAS, but also more severe nocturnal desaturation and hypercapnia as compared with children with uncomplicated OSAS.

Neuropsychological functioning in preschool-age children with sickle cell disease: the role of illness-related and psychosocial factors.

Cognitive and academic deficits have been identified in school-aged children with sickle cell disease (SCD). However, there have been very few identified studies that examine neuropsychological functioning in preschool-age children with SCD. It is important to understand effects of SCD from a developmental perspective and to consider the contribution of environmental factors in this at-risk population. Neuropsychological functioning of preschool-age children with SCD and no history of overt stroke (n = 26) was examined across several domains (language, immediate memory/brief attention, visuospatial/visuoconstructional, motor/visuomotor). The mean Full Scale IQ for the sample was 89.0. Performance on the Immediate Memory/ Brief Attention domain was significantly higher than the other domains, although the pattern of performance was relatively consistent, with mean standard scores ranging from 88.0 to 95.0. Disease severity was not significantly related to cognitive functioning in this group of young children with SCD. Socioeconomic status (SES) was significantly correlated with most domain scores and, based on regression analyses, accounted for 18% to 47% of the variance in functioning. Psychosocial factors, such as number of children living in the home and parental stress levels, were negatively associated with Motor/Visuomotor skills, and weekly hours in school/day care was positively associated with language-related skills. Results suggest that, at this young age, psychosocial risk factors appear to be appropriate targets for intervention, with the goal of improving long-term outcome in children with SCD. Further investigations should include comparison to a matched control group.

Chronic sorrow and coping in families of children with epilepsy.

Epilepsy, a common problem in child neurology, affects the entire family. There is a potential for such psychosocial consequences as parental chronic sorrow and alterations in coping. In this study, 67 parents completed brief questionnaires about their sorrow and coping styles. Results demonstrated chronic sorrow as measured by the Adapted Burke Questionnaire (10.45 +/- 7.9). Interestingly, the total score was not significantly different between parents of children with refractory and nonrefractory epilepsy or parents of children with comorbid or without comorbid conditions. Selection of the individual item disbelief, however, was significantly increased in parents of children with nonrefractory epilepsy, and selection of the item anger was significantly increased in parents of children with comorbid conditions. Parental coping styles were similar to those reported in the normative data for the instrument used, the Coping Health Inventory for Parents (CHIP). The correlation between chronic sorrow and coping was significant between the grief component of sorrow and Coping Pattern II of the CHIP. Implications for practice include earlier identification of parental feelings of sorrow and coping styles, which may contribute to a positive outcome.

Bruxism in children: effect on sleep architecture and daytime cognitive performance and behavior.

STUDY OBJECTIVES: Sleep bruxism is an involuntary mandibular movement with tooth grinding during sleep. The prevalence of sleep bruxism in children is high and may lead to frequent arousals with altered daytime functioning. We investigated the sleep architecture, the incidence of gastroesophageal reflux, and the daytime cognitive behavioral functioning in a group of children with sleep bruxism. DESIGN-PATIENTS: This prospective pilot study included 10 children. Polysomnographic data with pH-probe analysis was compared with 10 age- and sex-matched controls. Each patient completed a dental evaluation, a nighttime polysomnogram, and cognitive behavioral tests (Kaufman Brief Intelligence Test and Achenbach Child Behavior Checklist). RESULTS: Eight of 10 children had clinically significant bruxism and the 2 remaining patients had recent teeth exfoliation. There was no difference on sleep architecture between patients and controls, except for a higher arousal index for the bruxism group (36.7 vs 20.7, p < .007). Sleep bruxism occurred more frequently in stage 2 and rapid eye movement sleep, with arousals in 66% of the cases. There was no relationship of bruxism to gastroesophageal reflux or intelligence. However, 40% of the patients had elevated scores on the Achenbach Child Behavior Checklist, indicating significant attention and behavior problems, and there were moderate correlations between the arousal index and several of the behavior-problem scales from the Achenbach Child Behavior Checklist (0.5 to 0.6). CONCLUSIONS: The data suggest that children with bruxism have a higher arousal index, which may be associated with an increased incidence of attention-behavior problems. Future studies investigating pediatric sleep bruxism will need to focus on behavior issues that may be prevalent in this population.

Exposure to Violence and Virologic and Immunological Outcomes Among Youth With Perinatal HIV in the Pediatric HIV/AIDS Cohort Study.

PURPOSE: Exposure to violence in childhood has been linked to adverse health outcomes. Little is known about the prevalence and relationship of youth and caregiver violence exposure to clinical outcomes among youth with perinatal human immunodeficiency virus (HIV) infection (PHIV). We evaluated associations of youth and caregiver violence exposure with unsuppressed viral load (VL) (HIV RNA > 400 copies/mL) and CD4% <25% among 8- to 15-year-old participants with PHIV in the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol. METHODS: Annual clinical examination, record abstraction, and interview data were collected, including youth report of recent exposure to violence and caregivers' self-report of being assaulted/abused in adulthood. Multivariable logistic regression methods were used to calculate adjusted odds ratios for unsuppressed VL and CD4% <25%, controlling for sociodemographic characteristics. RESULTS: Among 268 youth with PHIV (53% girls, mean age 12.8 years, 21% white, 42% with household income <$20,000/year), 34% reported past year violence exposure; 30% had a caregiver who reported being assaulted in adulthood. One quarter of youth (24%) had unsuppressed VL and 22% had CD4% <25%. Youth who were exposed to violence in the past year versus those who were not had elevated odds of unsuppressed VL. Youth with indirect exposure to violence in the past year versus those without had elevated odds of unsuppressed VL and CD4% <25% in adjusted models. CONCLUSIONS: Youth with PHIV report a high prevalence of recent violence exposure, which was associated with poor virologic and immunologic outcomes. Reducing violence and providing support to youth with violence exposure and PHIV may improve health outcomes.

Prevalence, incidence, and persistence of psychiatric and substance use disorders among mothers living with HIV.

OBJECTIVE: To evaluate prevalence, incidence, remission, and persistence of psychiatric and substance use disorders among HIV-infected mothers and identify biopsychosocial correlates. METHODS: HIV-infected mothers (n = 1223) of HIV-exposed uninfected children enrolled in a prospective cohort study; HIV-uninfected mothers (n = 128) served as a comparison group. Mothers provided sociodemographic and health information and completed the Client Diagnostic Questionnaire (CDQ). Prevalence of any psychiatric or substance use disorder at initial evaluation was compared between the 2 groups. Incident, remitting, and persisting disorders were identified for 689 mothers with HIV who completed follow-up CDQs. We used logistic regression to evaluate adjusted associations of biopsychosocial characteristics with presence, incidence, remission, and persistence of disorders. RESULTS: Thirty-five percent of mothers screened positive for any psychiatric or substance use disorder at initial evaluation, with no difference by maternal HIV status (P = 1.00). Among HIV-infected mothers, presence of any disorder was associated with younger age [adjusted odds ratio (aOR): 1.39; 95% CI: 1.09 to 1.75], single parenthood (aOR: 1.35; 95% CI: 1.08 to 1.68), and functional limitations (aOR: 2.29; 95% CI: 1.81 to 2.90). Incident disorders were associated with functional limitations (aOR: 1.92; 95% CI: 1.10 to 3.30). Among HIV-infected mothers with a disorder at initial evaluation (n = 238), 61% had persistent disorders. Persistent disorders were associated with lower income (aOR: 2.44; 95% CI: 1.33 to 4.76) and functional limitations (aOR: 3.19; 95% CI: 1.87 to 5.48). Receipt of treatment for any disorder was limited: 4.5% at study entry, 7% at follow-up, 5.5% at both entry and follow-up. CONCLUSIONS: Psychiatric and substance use disorders remain significant comorbid conditions among HIV-infected mothers and require accessible evidence-informed treatment.
