RESUMEN
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.
RESUMEN
Acute hepatic porphyria (AHP) is a group of rare genetic diseases of heme biosynthesis resulting in severe neurovisceral attacks and chronic complications that negatively impact patients' well-being. This study evaluated the impacts of AHP on patients' physical and emotional health from a global perspective. Adult patients from the United States, Italy, Spain, Australia, Mexico, and Brazil with AHP with >1 porphyria attack within the past 2 years or receiving intravenous hemin and/or glucose for attack prevention completed an online survey assessing demographics, health characteristics, and patient-reported outcomes. Results were analyzed collectively and by patient subgroups. Ninety-two patients with AHP across the six countries completed the survey. More than 70% of patients reported that their physical, emotional, and financial health was fair or poor. Among patients who reported pain, fatigue, and muscle weakness, 94.3%, 95.6%, and 91.4%, respectively, reported that these symptoms limited daily activities. Moderate to severe depression was present in 58.7% of patients, and moderate to severe anxiety in 48.9% of patients. Of the 47% of patients who were employed, 36.8% reported loss in productivity while at work. Among patients, 85.9% reported that they had to change or modify goals that were important to them because of AHP. Aside from differences in healthcare utilization and pain severity, scores did not significantly vary with attack rate or use of hemin or glucose prophylactic treatments. AHP substantially impacts patients' physical and emotional well-being, regardless of hemin or glucose prophylactic treatment or frequency of attacks. This multinational study demonstrates that there is substantial disease burden for patients with AHP, even among those experiencing sporadic attacks or using prophylactic treatment.
RESUMEN
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.
