RESUMO
BACKGROUND: Patients with atopic dermatitis (AD) have systemic biomarker dysregulation that differs by age group; however, the proteomic characteristics of these age-based changes are unknown. OBJECTIVE: To profile blood proteins of patients with AD across different age groups versus age-appropriate controls. METHODS: Using the Olink high-throughput proteomic platform, we profiled 375 serum proteins of 20 infants (age, 0-5 years), 39 children (age, 6-11 years), 21 adolescents (age, 12-17 years), and 20 adults (age, ≥18 years) with moderate-to-severe AD and 83 age-appropriate controls. RESULTS: Each group presented a distinct systemic proteomic signature. Th2-related proteins were increased in infant AD and further intensified with age through adolescence and adulthood (interleukin 4/CCL13/CCL17). In contrast, Th1 axis down-regulation was detected in infants with AD and gradually reversed to increased Th1 products (interferon γ/CXCL9/CXCL10/CCL2) in patients with AD from childhood to adulthood. Despite their short disease duration, infants already had evidence of systemic inflammation, with significant upregulation of innate immunity (interleukin 17C/ interleukin-1RN), T-cell activation/migration (CCL19), Th2 (CCL13/CCL17), and Th17 (PI3) proteins. Adults with AD present unique upregulation of cardiovascular proteins related to coagulation and diabetes. LIMITATIONS: Cross-sectional observational study with a single time point. CONCLUSION: Systemic immune signatures of AD are age-specific beyond the shared Th2 immune activation. These data advocate for precision medicine approaches based on age-specific AD profiles.

BACKGROUND: Fatigue is a symptom that can negatively impact patients' quality of life. However, the relationship of AD with fatigue has not been fully studied, especially in children. OBJECTIVE: To determine the prevalence of fatigue in AD patients, and whether AD severity, demographics and comorbidities are associated with increased fatigue in children. METHODS: A cross-sectional observational study was performed among 248 children with AD. Paediatric patients (ages 8-17 years) and parents (of children ages 0-17 years) completed a questionnaire, including demographics, history of atopic comorbidities and validated severity measures of AD, itch, pain, sleep disturbance, sleep-related impairment and fatigue. AD severity was also assessed by clinician-reported Eczema Area and Severity Index (EASI), Scoring AD (SCORAD) and Investigator's Global Assessment (IGA). Fatigue was assessed using Patient Reported Outcome Measurement Information System (PROMIS) Pediatric Fatigue T-score. RESULTS: Most children with AD had no (38.6%) or mild (32.1%) fatigue, with fewer having moderate (27.2%) or severe (2%) fatigue. Moderate/severe PROMIS Pediatric fatigue T-scores were increased with moderate (25.7%/1.4%) and severe (39.3%/5.4%) IGA vs. mild IGA (18.0%/0.0%) and those with 5-6 (44.4%/0.0%) and 7 (44.2%/5.2%) nights of SD from eczema. Moderate-severe PROMIS Pediatric Fatigue T-scores were associated with history of hay fever (adjusted OR [95% Cl]: 2.803 [1.395-5.632]) and family income (<$100,000: 3.049 [1.294-7.181]), but inversely with Black (0.40 [0.168-0.969]) and AAPI (0.285 [0.094-0.859]) race. In multivariable regression models controlling for demographic factors, PROMIS Pediatric Fatigue T-score was significant with more severe scores for IGA, POEM, EASI, SCORAD, NRS-itch, SCORAD-itch, average itch in the past 7 days, PROMIS Pediatric Pain severity, PROMIS Pediatric SD, PROMIS Pediatric SRI, SCORAD-sleep and more frequent SD from AD. CONCLUSIONS: Fatigue is a common yet underappreciated symptom in children with AD, particularly those with moderate-severe AD, and warrants more attention in clinical practice and trials.

Retrospective chart review was conducted to identify the clinical features of Henoch Schonlein purpura (HSP) in five children with inflammatory bowel disease (IBD). All five children, four of which were on anti-TNF therapies, experienced the onset of HSP after their IBD diagnosis. HSP averaged 20.8 months in duration. The patients in our cohort, particularly those on anti-TNF therapy for inflammatory bowel disease, experienced chronic and recurrent courses of HSP.

Extensive research is underway to discover a safe and effective vehicle to deliver the vaccines at the desired cutaneous site. These efforts majorly comprise the development of a fit-to-purpose vehicle for in-situ intracutaneous vaccine delivery for achieving the systemic cellular and humoral response to combat infectious diseases. Advancements in nanoscience, bioengineering, and skin science provided much support to vaccine adjuvant development. However, the bench-to-bed side translation of vaccines is still unsatisfactory. A skilfully designed vaccine delivery program aiming to translate the product into market use must address safety, efficacy, scaleup, reproducibility, cost of production, self-administrative potential, and regulatory concerns. This review provides deep insights into skin immunization approaches like mucosal vaccines, cellular/molecular immunological responses, and antigen-adjuvant combinations in modulating immunity. Further, the manuscript discusses distinct vaccine delivery systems used to date for engineering skin immunization, including microparticles, nanoparticles, spherical nucleic acids, STAR particles, niosomes, dendrimers, ethosomes, liposomes, and microneedles. The manuscript will interest researchers working towards developing a next-generation fit-to-purpose vehicle for intracutaneous vaccine delivery.

Given increased focus on health spending, this investigation aims to compare trends in pediatric Medicaid and private insurance spending on type of service from 2002 to 2014 in order to inform policy and research. A repeated cross-sectional analysis of 2002 to 2014 National Health Expenditure Accounts data was conducted. Total spending, per capita spending, and compounded annual growth rates for type of service were determined for children ages 0 to 18 at the national level. Per capita spending growth was higher for private insurance than for Medicaid, and the areas of high per capita spending growth differed for private insurance and Medicaid. While Medicaid spent more per capita on hospital care than private insurance, private insurance demonstrated greater per capita spending growth on hospital care than Medicaid (8.49% vs 1.99%, respectively). Conversely, per capita spending on home health care grew more for Medicaid (6.79%) than for private insurance (3.18%). Trends in private insurance and Medicaid overall and per capita spending differ. Medicaid experienced higher annual growth in total spending than per capita spending, while private insurance had greater annual growth in per capita spending than total spending. Growth in private insurance per capita spending was higher than growth in Medicaid per capita spending, but growth in Medicaid total spending was higher than growth in private insurance total spending. These data suggest that Medicaid and private insurance may have different drivers of spending growth, highlighting the need for policy makers to examine spending patterns by payer. Further research to determine why such differences in spending growth exist will better inform efforts to increase health care value.

Decreased health literacy is associated with worse outcomes for a variety of dermatologic conditions. Hispanic adults have the lowest average health literacy of any racial or ethnic group in the United Sates. Although patients are increasingly using online patient education materials (PEMs) for dermatologic care, limited information exists regarding the readability of these resources. The objective of this study is to evaluate the readability of online Spanish language PEMs in dermatology. Online Spanish language PEMs relevant to dermatology were gathered from the United States National Library of Medicine (USNLM) MedlinePlus health library and top Google, Yahoo, and Bing search results for "Spanish patient education dermatology." Spanish text was analyzed for readability using two validated programs: Spanish Lexile Analyzer and Índice Flesch-Szigriszt (INFLESZ). Pearson's correlation coefficient was used to examine the association between the two readability measures. ANOVA without post hoc correction was performed to determine variability between PEMs. A total of 254 Spanish language PEMs were collected and analyzed from nine online sources. The average article length was 601 words. The average Lexile measure was 1005 L (SD = 144 L) and the average INFLESZ score was 64.60 (SD = 7.53). Readability scores equated to an 8-10th grade reading level and was varied based on the source of information (p < 0.001). Online Spanish language PEMs related to dermatology are generally written at a reading level that exceeds national recommendations and may reduce comprehension for Hispanic patients. Targeted initiatives to address and improve online health information for Spanish-speaking patients are warranted.

IMPORTANCE: Medicare enrollment, dermatologist utilization of Medicare, and dermatologic procedural volume have all increased over time. Despite this, there are limited studies evaluating changes in Medicare reimbursement within dermatology. OBJECTIVE: To identify trends in Medicare reimbursement for 46 common dermatologic procedures from 2007 to 2021. DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional study, reimbursement data were obtained from the Centers for Medicare & Medicaid Services Physician Fee Schedule for commonly used dermatologic Current Procedural Terminology (CPT) codes from 2007 to 2021. The CPT codes in several major dermatologic categories were analyzed, including skin biopsy, shave removal, benign/premalignant/malignant destruction, benign/malignant excision, Mohs micrographic surgery, simple/intermediate/complex repair, flap, graft, and laser/phototherapy. All procedure prices were adjusted for inflation to January 2021 dollar value. MAIN OUTCOMES AND MEASURES: The primary outcomes were percentage changes and cumulative annual growth rates of pricing for each dermatologic procedure. RESULTS: From 2007 to 2021, there was a mean decrease in dermatologic procedure reimbursement of -4.8% after adjusting for inflation. Mean inflation-adjusted changes in reimbursements during this time period significantly varied by procedure type, including skin biopsy (+30.3%), shave removal (+24.5%), benign/premalignant/malignant destruction (-7.5%), Mohs micrographic surgery (-14.4%), benign/malignant excision (-3.9%), simple/intermediate/complex repair (-9.9%), flap repair (-14.1%), graft repair (-12.0%), and laser/phototherapy (-6.6%; P < .001). Changes in reimbursement did not vary by anatomical risk categories. CONCLUSIONS AND RELEVANCE: The findings of this cross-sectional analysis suggest that changes in Medicare reimbursement can have several downstream effects, including concomitant private insurance changes and decreased patient access. Future adjustments in reimbursement should balance high-value care with sustainable pricing to optimize patient access.
