AI Article Synopsis

  • The study aimed to investigate the prevalence of atopic diseases in individuals with psoriasis, using data from over 90,000 employees in Germany aged 16 to 70.
  • Results showed that 2% of participants had psoriasis, and while 32.7% had a history of atopic conditions, those with psoriasis were less likely to have these conditions compared to those without it.
  • Despite a lower prevalence, the study indicates that certain atopic diseases might still impact individuals with psoriasis, highlighting the need for further research on the relationship between these conditions.

Article Abstract

Background: Large-scale data on the association between psoriasis and atopic diseases are scarce.

Objectives: To evaluate the concomitant prevalence of atopic conditions and psoriasis.

Materials & Methods: In this cross-sectional study, employees between 16 and 70 years of age were examined in more than 400 German companies by dermatologists, between 2006 and 2014. Two different definitions of atopic conditions were applied: "current atopic condition" (point prevalence) and "current or previous atopic condition" (lifetime prevalence). Bivariate comparisons as well as logistic regression analyses controlling for age and sex were performed.

Results: In total, 90,265 persons were included in the study; 58.5% male; mean age: 43.2 ± 10.7 years. Point prevalence for psoriasis was 2.0% (n = 1,788), and lifetime prevalence of atopic conditions was 32.7% (n = 29,501). Atopic conditions were significantly less frequent (29.6%, n = 530) in persons with psoriasis compared to those without psoriasis (32.7 %, n = 28,917; OR = 0.865; CI: 0.781 - 0.959). Concurrent and prior atopic conditions were observed in 13.7% (n = 245) of persons with psoriasis versus 15.6% without psoriasis (n = 13,835; OR = 0.857; CI: 0.748-0.981). Controlling for age and sex, significant differences were found between persons with and without psoriasis for symptomatic atopic conditions such as hypersensitivity to pollen (OR = 0.864; CI: 0.748-0.997) and animal epithelia (OR = 0.764; CI: 0.609-0.958).

Conclusion: Even though the prevalence of atopic diseases is less frequent in individuals with psoriasis than in those without psoriasis, this study suggests that atopic conditions such as atopic dermatitis may also play a relevant role in psoriasis.

Background: Sleep disturbances are common and distressing among patients with atopic dermatitis (AD), often resulting in a cycle of worsening skin conditions. Among various factors affecting sleep in AD, cervical spine movement has been suggested to influence sleep quality; however, these studies mostly relied on subjective measures. Owing to the lack of objective and quantitative analyses of cervical spine movement, its association with sleep disturbances remains poorly understood.

Introduction: Atopic dermatitis (AD) is a common and relapsing skin disease characterized by skin barrier dysfunction, inflammation, and chronic pruritus. Both cutaneous barrier dysfunction and immune dysregulation are critical etiologies of the pathology of AD. Although various anti-inflammatory pharmacological agents, including cytokine inhibitors and signaling pathway blockers, have been developed recently, keeping the skin clean is of utmost importance in maintaining physiological cutaneous barrier function and avoiding an AD flare.

Numerous studies have reported on the types of aeroallergen sensitization in various pediatric allergic diseases, but limited data compared the types of aeroallergen sensitization across different pediatric allergic diseases. The aim of this study is to explore the nature and significance of aeroallergen sensitization in diverse pediatric allergic conditions. A comparative analysis was carried out on aeroallergen sensitization in children suffering from allergic diseases who visited the Otolaryngology, Respiratory, and Dermatology Departments between January 2019 and December 2023.
