RESUMO
BACKGROUND: Few large-scale international studies broadly characterized the burden of atopic dermatitis (AD) across age groups among children and adolescents. OBJECTIVE: To better characterize the AD burden in pediatric subjects by disease severity. METHODS: This cross-sectional, web-based survey of pediatric subjects (6 months to <18 years old) was conducted in 18 countries representing North America, Latin America, Europe, Middle East/Eurasia, and East Asia. Subjects with diagnosed AD were identified based on the International Study of Asthma and Allergies in Childhood criteria and self-/parent-report of ever being told by a physician that they/their child had eczema. AD severity was assessed using Patient Oriented Eczema Measure and Patient Global Assessment. Outcomes included measures of itch, skin pain, sleep, health-related quality-of-life (HRQoL), missed school days, and atopic comorbidities. RESULTS: The survey included 1489 children 6 months to < 6 years; 2898 children 6 to < 12 years; and 3078 adolescents 12 to < 18 years diagnosed with AD. Although the burden of mild AD was substantial, pediatric subjects with moderate or severe AD had more itch, skin pain, sleep problems, and impaired HRQoL, and missed more school days relative to those with mild AD; greater burden was observed among severe relative to moderate AD. At least one atopic comorbidity was present in 92·5% of all respondents. CONCLUSIONS: These results highlight the burden of AD in pediatric subjects especially those with moderate-to-severe disease, and suggest the need for assessments that include the impact of AD on function and daily life.
RESUMO
OBJECTIVE: To evaluate the impact of atopic dermatitis on families of pediatric patients. STUDY DESIGN: This cross-sectional, web-based survey of children/adolescents (6 months to <18 years old) with atopic dermatitis and their parents and caregivers was conducted in 18 countries encompassing North America, Latin America, Europe, Middle East/Eurasia, and East Asia. Children and adolescents with atopic dermatitis and their parents and caregivers were identified by the International Study of Asthma and Allergies in Childhood criteria and ever being told by a physician that they had "eczema". Atopic dermatitis severity was assessed using the Patient-Oriented Eczema Measure and the Patient Global Assessment. Atopic dermatitis impact on families' lives was evaluated using the Dermatitis Family Impact questionnaire and stand-alone questions on hours of atopic dermatitis-related care (past week) and missed work days (past 4 weeks) owing to their child's atopic dermatitis. RESULTS: A total of 7465 pairs of pediatric participants with atopic dermatitis and their parents or caregivers were surveyed. Across age groups, the Dermatitis Family Impact questionnaire total score for all regions ranged from 7.1 to 8.6, 13.2 to 14.9, and 17.0 to 17.2 for Patient-Oriented Eczema Measure mild, moderate, and severe atopic dermatitis, respectively. Subscale scores showed that greater atopic dermatitis severity had a greater impact on all family life domains, including sleep and tiredness. No specific patterns or trends were observed across age groups. Time spent on childcare and missed work days increased with atopic dermatitis severity. CONCLUSIONS: Across pediatric age groups and geographic regions, greater atopic dermatitis severity was associated with a greater negative impact on physical, emotional, social, and economic components of family life.

BACKGROUND: Parents of children with atopic dermatitis (AD) report reduced quality of life and higher stress level, which could increase risk of psychiatric and pain disorders, and medication use. METHODS: By use of Danish national registries, we identified family members of all first-born Danish children born between 1 January 1995 and 31 December 2013 with a hospital diagnosis of AD, matched them 1:10 with family members of children without AD, and followed the cohorts over time. RESULTS: Mothers of children with hospital-managed AD had higher risk of filling a prescription for medications for depression, anxiety, pain and sleep problems, and of consulting a psychologist, but most associations disappeared after full adjustment. Siblings had higher risk of receiving a diagnosis for adjustment disorder, and fathers showed increased risk of filling a prescription for pain medication and of divorce, in crude but not adjusted models. CONCLUSIONS: The increased risk of study endpoints seen in mothers of children with hospital-managed AD was not explained by pediatric AD alone. Rather, the total burden in these families including parent and child morbidity and socioeconomic resources seems to explain these observations. The burden in families of children with AD may potentially affect the overall management of their child's AD.

BACKGROUND: Little is known on the current global prevalence of atopic dermatitis (AD) in the pediatric population. OBJECTIVE: To estimate the real-world global prevalence of AD in the pediatric population and by disease severity. METHODS: This international, cross-sectional, web-based survey of children and adolescents (6 months to <18 years old) was conducted in the following 18 countries: North America (Canada, United States), Latin America (Argentina, Brazil, Columbia, Mexico), Europe (France, Germany, Italy, Spain, United Kingdom), Middle East and Eurasia (Israel, Saudi Arabia, Turkey, United Arab Emirates, Russia), and East Asia (Japan, Taiwan). Prevalence was determined using the following 2 definitions: (1) diagnosed as having AD according to the International Study of Asthma and Allergies in Childhood (ISAAC) criteria and self- or parent-report of ever being told by a physician that they or their child child had AD (eczema); and (2) reported AD based on the ISAAC criteria only. Severity was assessed using the Patient Global Assessment (PtGA) and Patient-Oriented Eczema Measure (POEM). RESULTS: Among 65,661 responders, the 12-month diagnosed AD prevalence (ISAAC plus self-reported diagnosis) ranged from 2.7% to 20.1% across countries; reported AD (ISAAC only) was 13.5% to 41.9%. Severe AD evaluated with both PtGA and POEM was generally less than 15%; more subjects rated AD as mild on PtGA than suggested by POEM. No trends in prevalence were observed based on age or sex; prevalence was generally lower in rural residential settings than urban or suburban. CONCLUSION: This global survey in 18 countries revealed that AD affects a substantial proportion of the pediatric population. Although prevalence and severity varied across age groups and countries, less than 15% had severe AD.

BACKGROUND: The real-world persistence with dupilumab therapy for atopic dermatitis (AD) is unknown. OBJECTIVE: To characterize adults with AD who initiated dupilumab and evaluate persistence with dupilumab therapy. METHODS: This retrospective cohort study used the IBM MarketScan Commercial and Medicare database. Adults with AD who initiated dupilumab (first dispensation = index date) between March 28, 2017, and March 31, 2018, were identified and followed up until September 30, 2018, or disenrollment. Twelve months of continuous preindex enrollment were required to characterize baseline treatment history and comorbidities. Kaplan-Meier analysis was used to estimate dupilumab persistence at 6 and 12 months, assuming a 14-day injection frequency and a 30-day grace period. RESULTS: A total of 1963 adults were identified who initiated dupilumab (mean [SD] age 42.1 [15.7] years; 50.7% women; 49.8% with ≥1 atopic comorbidity). Baseline AD treatments included topical corticosteroids (81.6%), systemic corticosteroids (72.5%), and systemic immunosuppressants (22.8%). Dupilumab persistence (95% confidence interval) at 6 and 12 months was 91.9% (90.7%-93.2%) and 77.3% (75.0%-79.7%), respectively. Among 329 patients who discontinued dupilumab, the risk of reinitiation was 78.8% (95% confidence interval: 75.8%-81.7%) within an average of 4 months. CONCLUSION: Dupilumab persistence at 12 months was high, suggesting patient satisfaction with effectiveness, tolerability, and treatment regimen.

OBJECTIVE: Racial differences in the clinical nature of major depressive disorder (MDD) could contribute to treatment disparities, but national data with large samples are limited. Our objective was to examine black-white differences in clinical characteristics and treatment for MDD from one of the largest, national community samples of US adults. METHODS: Non-Hispanic black and white adults (n=32752) from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions produced data on 1866 respondents who met criteria for MDD based on the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) in the preceding 12 months. Outcome measures were depressive symptoms, comorbid psychiatric and medical disorders, disability, and treatment. RESULTS: Blacks with MDD had significantly higher odds of initial insomnia, early-morning awakening, and restlessness than whites. Odds of hypertension (odds ratio [OR), 2.16; 95% confidence interval [CI], 1.48-3.14), obesity (OR, 1.98; 95% CI, 1.45-2.69), and liver disease (OR, 3.68; 95% CI, 1.20-11.30) were higher among blacks than whites. In unadjusted models, blacks had greater impairment than whites in social and physical functioning. However, adjusting for sociodemographic characteristics eliminated these differences. Blacks were less likely than whites to receive outpatient services (OR, 0.51; 95% CI, 0.36-0.72) and be prescribed medications for MDD, but were more likely to receive emergency room and inpatient treatment. CONCLUSIONS: We found few racial differences in depressive symptoms, psychiatric comorbidity, and disability after adjusting for sociodemographic factors. Blacks' lower utilization of ambulatory treatment for MDD and greater medical comorbidity, emergency department use, and hospitalization suggests that management of MDD among blacks should be emphasized in primary care or other settings where treatment is more accessible.

Importance: Atypical antipsychotics (AAPs) are often used off-label to manage dementia-associated neuropsychiatric symptoms. In 2005, the US Food and Drug Administration (FDA) issued a boxed warning for the use of AAPs in elderly patients. The long-term association of this warning with health outcomes is unknown to date. Objective: To assess the long-term association of the 2005 FDA boxed warning on AAPs with psychiatric medication and opioid use, health events, and quality of life among elderly individuals with dementia. Design, Setting, and Participants: For this cross-sectional study, data were analyzed from the household component of the Medical Expenditure Panel Survey (MEPS), the National Ambulatory Medical Care Survey (NAMCS), and the National Hospital Ambulatory Medical Care Survey (NHAMCS) fielded between January 1, 1996, and December 31, 2014. This interrupted time-series analysis applied to 3-year moving means derived from the 1996-2014 MEPS, NAMCS, and NHAMCS. All survey respondents included in this analysis were 65 years or older and had dementia. Data analysis was performed from December 1, 2017, to March 15, 2018. Exposures: The 2005 FDA boxed warning on AAPs. Main Outcomes and Measures: Use of psychiatric medications and opioids, prevalence of cerebrovascular and cardiovascular events, prevalence of falls and/or fractures, 2-year mortality, and health-related quality of life assessed by the Medical Outcomes Study 12-Item Short-Form Health Survey scores. Results: A total of 2430 (MEPS) and 5490 (NAMCS and NHAMCS) respondents were identified, corresponding to weighted populations of 22â¯996â¯526 (MEPS) and 65â¯502â¯344 (NAMCS and NHAMCS) noninstitutionalized elderly individuals with dementia (mean [SD] age, 81.06 [1.13] years; 63.1% female). In the MEPS sample, compared with before 2005, AAP use (from an annual slope of 0.99 to -0.18 percentage points), cerebrovascular events (0.75 to -0.50 percentage points), and falls and/or fractures (-1.72 to -0.40 percentage points) decreased and opioid use (0.04 to 1.29 percentage points), antiepileptic use (-0.42 to 1.21 percentage points), cardiovascular events (-0.13 to 1.30 percentage points), and 2-year mortality risk (-0.68 to 0.18 percentage points) increased. Health-related quality of life remained relatively unchanged. The NAMCS and NHAMCS sample yielded similar findings. Conclusions and Relevance: These data suggest that the 2005 FDA boxed warning was associated with some unintended negative patient outcomes.

The rapid growth of antipsychotic medication use among publicly insured children in the early and mid-2000s spurred new state efforts to monitor and improve prescription behavior. A starting point for many oversight initiatives was the foster care system, where most of the children are insured publicly through Medicaid. To understand the context and the effects of these initiatives, we analyzed patterns and trends in antipsychotic treatment of Medicaid-insured children in foster care and those in Medicaid but not in foster care. We found that the trend of rapidly increasing use of antipsychotics appears to have ceased since 2008. Children in foster care treated with antipsychotic medications are now more likely than other Medicaid-insured children to receive psychosocial interventions and metabolic monitoring for the side effects of the medications. However, challenges persist in increasing safety monitoring and access to psychosocial treatment. Development of specialized managed care plans for children in foster care represents a promising policy opportunity. New national quality measures for safe and judicious antipsychotic medication use are also now available to guide improvement. Oversight policies developed for foster care appear to have potential for adaptation to the broader population of Medicaid-covered children.

Childhood maltreatment increases the risk for adult personality disorders (PDs), but several PDs or maltreatment types co-occur. Specificity of maltreatment-personality associations is poorly understood. Using a representative US population sample, we identified specific associations between maltreatment types (sexual, physical and emotional abuse and physical and emotional neglect) and PDs after controlling for basic demographics, parental psychopathology, co-occurring maltreatment types and comorbid PD. We then examined interactions of gender and maltreatment in predicting PDs. Each maltreatment type significantly predicted three-four PDs. Borderline and schizotypal PDs were most strongly predicted by sexual abuse, antisocial by physical abuse and avoidant and schizoid by emotional neglect. Specific vulnerabilities differ by gender; maltreated boys may respond with attention seeking and girls with social withdrawal. Findings highlight the importance of evaluating all forms of maltreatment even when they co-occur and can inform development of interventions to prevent personality pathology in at-risk children.

AIMS: Little is known about the differential effects of independent and substance-induced major depression on the longitudinal course of alcohol, cocaine and heroin disorders when studied prospectively. DESIGN: Consecutively admitted in-patients, evaluated at baseline, 6-, 12- and 18-month follow-ups. SETTING: Baseline evaluations in a short-stay in-patient urban community psychiatric hospital unit. PARTICIPANTS: Adults (n = 250) with current DSM-IV cocaine, heroin and/or alcohol dependence at baseline. MEASUREMENTS: The Psychiatric Research Interview for Substance and Mental Disorders (PRISM), used to evaluate independent and substance-induced major depression, alcohol, cocaine and heroin dependence, and other psychiatric disorders. Outcomes for each substance: (i) time (weeks) from hospital discharge to first use; (ii) time from discharge to onset of sustained (≥26 weeks) remission from dependence; (iii) time from onset of sustained remission to relapse. FINDINGS: Substance-induced major depression significantly predicted post-discharge use of alcohol, cocaine and heroin (hazard ratios 4.7, 5.3 and 6.5, respectively). Among patients achieving stable remissions from dependence, independent major depression predicted relapse to alcohol and cocaine dependence (hazard ratios 2.3 and 2.7, respectively). CONCLUSIONS: Substance-induced and independent major depressions were both related to post-discharge use of alcohol, cocaine and heroin. The findings suggest the importance of clinical attention to both types of depression in substance abusing patients.

BACKGROUND: A number of changes have been proposed and investigated in the criteria for substance use disorders in DSM-5. However, although clinical utility of DSM-5 is a high priority, relatively little of the empirical evidence supporting the changes was obtained from samples of substance abuse patients. METHODS: Proposed changes were examined in 663 patients in treatment for substance use disorders, evaluated by experienced clinicians using the Psychiatric Research Interview for Substance and Mental Disorders (PRISM). Factor and item response theory analysis was used to investigate the dimensionality and psychometric properties of alcohol, cannabis, cocaine and heroin abuse and dependence criteria, and craving. RESULTS: The seven dependence criteria, three of the abuse criteria (hazardous use; social/interpersonal problems related to use; neglect of roles to use), and craving form a unidimensional latent trait for alcohol, cannabis, cocaine and heroin. Craving did not add significantly to the total information offered by the dependence criteria, but adding the three abuse criteria and craving together did significantly increase total information for the criteria sets associated with alcohol, cannabis and heroin. CONCLUSION: Among adult patients in treatment for substance disorders, the alcohol, cannabis, cocaine and heroin criteria for dependence, abuse (with the exception of legal problems), and craving measure a single underlying dimension. Results support the proposal to combine abuse and dependence into a single diagnosis in the DSM-5, omitting legal problems. Mixed support was provided for the addition of craving as a new criterion, warranting future studies of this important construct in substance use disorders.

AIMS: DSM-IV drug use disorders, a major public health problem, are highly comorbid with other psychiatric disorders, but little is known about the role of this comorbidity when studied prospectively in the general population. Our aims were to determine the role of comorbid psychopathology in the 3-year persistence of drug use disorders. DESIGN AND SETTING: Secondary data analysis using waves 1 (2001-02) and 2 (2005-05) of the National Epidemiologic Survey on Alcohol and Related Conditions. PARTICIPANTS: Respondents with current DSM-IV drug use disorder at wave 1 who participated in wave 2 (n = 613). MEASUREMENTS: Alcohol Use Disorders and Associated Disabilities Interview Schedule IV (AUDADIS-IV) obtained DSM-IV Axis I and II diagnoses. Persistent drug use disorder was defined as meeting full criteria for any drug use disorder between waves 1 and 2. FINDINGS: Drug use disorders persisted in 30.9% of respondents. No Axis I disorders predicted persistence. Antisocial [odds ratio (OR) = 2.75; 95% confidence interval (CI): 1.27-5.99], borderline (OR = 1.91; 95% CI: 1.06-3.45) and schizotypal (OR = 2.77; 95% CI: 1.42-5.39) personality disorders were significant predictors of persistent drug use disorders, controlling for demographics, psychiatric comorbidity, family history, treatment and number of drug use disorders. Deceitfulness and lack of remorse were the strongest antisocial criteria predictors of drug use disorder persistence, identity disturbance and self-damaging impulsivity were the strongest borderline criteria predictors, and ideas of reference and social anxiety were the strongest schizotypal criteria predictors. CONCLUSIONS: Antisocial, borderline and schizotypal personality disorders are specific predictors of drug use disorder persistence over a 3-year period.

CONTEXT: Little is known about the role of a broad range of personality disorders in the course of substance use disorder (SUD) and whether these differ by substance. The existing literature focuses mostly on antisocial personality disorder and does not come to clear conclusions. OBJECTIVE: To determine the association between the 10 DSM-IV personality disorders and the persistence of common SUDs in a 3-year prospective study of a national sample. DESIGN: Data were drawn from participants in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) who had alcohol dependence (n = 1172), cannabis use disorder (n = 454), or nicotine dependence (n = 4017) at baseline and who were reinterviewed 3 years later. Control variables included demographic characteristics, family history of substance disorders, baseline Axis I disorders and treatment status, and prior SUD duration. Main Outcome Measure Persistent SUD, defined as meeting full criteria for the relevant SUD throughout the 3-year follow-up period. RESULTS: Persistent SUD was found among 30.1% of participants with alcohol dependence, 30.8% with cannabis use disorder, and 56.6% with nicotine dependence at baseline. Axis I disorders did not have strong or consistent associations with persistent SUD. In contrast, antisocial personality disorder was significantly associated with persistent alcohol, cannabis, and nicotine use disorders (adjusted odds ratios, 2.46-3.51), as was borderline personality disorder (adjusted odds ratios, 2.04-2.78) and schizotypal personality disorder (adjusted odds ratios, 1.65-5.90). Narcissistic, schizoid, and obsessive-compulsive personality disorders were less consistently associated with SUD persistence. CONCLUSIONS: The consistent findings on the association of antisocial, borderline, and schizotypal personality disorders with persistent SUD indicates the importance of these personality disorders in understanding the course of SUD. Future studies should examine dimensional representations of personality disorders and the role of specific components of these disorders, biological and environmental contributors to these relationships, and potential applications of these findings to treatment development.

OBJECTIVE: Prescriptions for anxiety medications have increased substantially in recent years. Individuals with anxiety disorders are at risk of nonmedical use of these medications, but information about whether this risk is elevated among patients with a prescription for such medications is lacking. The authors compared risk of nonmedical use in individuals in a national sample with and without a prescription for anxiety medication and identified characteristics associated with nonmedical use. METHOD: Data were drawn from face-to-face surveys of 34,653 adult participants in the National Epidemiologic Survey on Alcohol and Related Conditions. The risk of nonmedical use of prescription anxiety medication and associated drug use disorders was computed for individuals who had or had not ever received a prescription for anxiety medication; among those who had received a prescription, characteristics associated with nonmedical use were analyzed. RESULTS: Prescription of anxiety medication was associated with lifetime and past-year nonmedical use (odds ratios, 1.6 and 1.9, respectively) and lifetime DSM-IV abuse or dependence (odds ratio, 2.6). Among respondents who received a prescription (N=4,294), nonmedical use was associated with male sex, younger age, white race, history of use of illicit drugs, history of other drug use disorders, and history of illegal behaviors. CONCLUSIONS: These results indicate that prescription for anxiety medications is associated with nonmedical use of these medications, although the direction of causality cannot be determined in this study. Although anxiety medications have clinical utility, greater clinical attention should be given to the potential for their abuse among patients at particular risk.
