Objectives: To characterize comorbidities, health-related quality-of-life (HRQoL), productivity, and healthcare resource use in adults with atopic dermatitis (AD) relative to those without AD, and to evaluate the impact of patient-reported AD severity on these outcomes.
Methods: Data were from the 2013 National Health and Wellness Survey (NHWS), which collected self-reported information on demographics, comorbidities, HRQoL (SF-36v2 Health Survey), productivity (Work Productivity and Impairment questionnaire [WPAI]), and healthcare utilization, which were weighted to the US general population. The AD cohort consisted of subjects who reported that they experienced AD within the past 12 months (n = 428), and the non-AD cohort included all subjects who did not report experiencing AD (n = 74,572); 366 AD subjects self-reported mild (n = 182) or moderate/severe (n = 184) disease. Univariable and multivariable analyses compared characteristics and outcomes between cohorts and between AD severity levels.
Results: The AD cohort was younger than non-AD cohort (44.3 vs. 46.6 years; P = 0.0033), and had a higher proportion of females (64.4% vs. 51.8%; P < 0.0001). Relative to the non-AD cohort, the AD cohort had a significantly higher prevalence of atopic conditions including nasal allergies (46.4% vs. 19.8%) and asthma (22.4% vs. 7.9%), and neuropsychiatric conditions such as anxiety (42.5% vs. 21.3%) and depression (37.2% vs. 20.9%) (all P < 0.0001). Units of resource use (healthcare practitioner visits, emergency room, hospitalizations) were higher (all P < 0.05) and HRQoL was poorer (P < 0.0001) with AD. On the WPAI, AD employees reported almost twice as much lost work productivity as non-AD employees (30.0% vs. 16.3%; P < 0.0001). No clear differences in outcomes were observed among patient-reported AD severity categories, except greater impairment of work productivity and daily activities in those with moderate/severe AD relative to mild.
Conclusions: The significant burden associated with AD relative to those without AD suggests an unmet need for more effective management strategies. There also appears to be a need for further characterization of disease severity and its impact on HRQoL.

Sphingolipids are an essential lipid component of the skin barrier with alterations in skin sphingolipid composition associated with multiple skin disorders including psoriasis, atopic dermatitis, and ichthyosis. Contributions to skin sphingolipid abundance are not well characterized, thus the main method of modulating skin lipid levels is the topical application of creams rich with sphingolipids at the skin surface. Evidence that diet and gut microbiome function can alter skin biology proposes an intriguing potential for the modulation of skin lipid homeostasis through gut microbial metabolism, but potential mechanisms of action are not well understood.

Reduced fidelity of these vacuolar organelles is increasingly being recognized as important in instigating cell-autonomous immune cell activation. We reasoned that exploring the role of BLOC1S1 in CD4 T cells, may further advance our understanding of regulatory events linked to mitochondrial and/or endolysosomal function in adaptive immunity.

Background: Dupilumab is a safe and effective treatment for moderate to severe atopic dermatitis (AD), but real-world data in pediatric patients in China are limited. Currently, there is no exploration of changes in blood cell counts derived indexes in pediatric patients, especially under 6 years old.
Purpose: To investigate the changes in blood cell counts derived indexes before and after dupilumab treatment in Chinese children with AD, the relationship with clinical scores, and the potential role of these indexes on treatment efficacy.

Sphingosylphosphorylcholine (SPC) is one of sphingomyelin-derived sphingolipids. SPC levels are increased in ascitic fluids of ovarian cancer patients and stratum corneum of atopic dermatitis (AD) patients. SPC has antitumor activity against several cancer cells by reducing proliferation and migration and increasing apoptosis .

While recent studies have demonstrated the involvement of the skin and gut microbiome in the pathogenesis of atopic dermatitis (AD), the influence of pharyngeal microbiota on AD remains unclear. This study aims to explore disparities in the composition of pharyngeal flora among AD patients and their potential role in the pathogenesis of AD. Between March and May 2023, 30 patients with AD at the outpatient department of Jiangsu Provincial Traditional Chinese Medicine Hospital were recruited, along with 20 healthy subjects, underwent 16S rRNA sequencing on pharyngeal swabs.
