Aim: This study aimed to examine the association between smoking type and the prevalence of atopic dermatitis and asthma in men and women.

Background: Cases of allergic diseases have been steadily increasing worldwide. Smoking is associated with serious diseases. Only a few studies have assessed the association between smoking and atopic dermatitis and asthma in adults, and gender difference studies are scarce despite a significant difference in smoking rates.

Methods: We conducted a secondary cross-sectional analysis of 17 886 adults with atopic dermatitis and 17 889 with asthma aged ≥19 years, using raw data from the Fifth Korea national Health and Nutrition Examination Survey (2010-2012).

Results: The prevalence of atopic dermatitis in men was not associated with active or passive smoking, whereas asthma prevalence in men was associated with indoor passive smoking exposure at home. We found that atopic dermatitis prevalence in women was associated with current smoking status, whereas asthma prevalence in women was associated with the presence of an indoor daily smoker at home and indoor passive smoking exposure at home.

Conclusion: Asthmatic adults should be informed of the hazards of passive smoking, and women with atopic dermatitis should in particular be dissuaded from smoking.

Itching tends to worsen at night in patients with itchy skin diseases, such as atopic dermatitis. Unconscious scratching during sleep can exacerbate symptoms, cause sleep disturbances, or reduce quality of life. Therefore, evaluating nocturnal scratching behaviour is important for better patient care.

Background: Inhibition of IL-4/IL-13 driven inflammation by dupilumab has shown significant clinical benefits in treatment of atopic dermatitis (AD).

Objective: To assess longitudinal protein and metabolite composition in AD skin during dupilumab treatment.

Methods: Skin tape strip (STS) were collected from lesional/non-lesional skin of 20 AD patients during 16-week dupilumab treatment and from 20 healthy volunteers (HV) followed for 16-weeks.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritus and a relapsing course, affecting approximately 25% of children and 4-7% of adults. This study evaluated the efficacy, safety, and quality-of-life impact of tralokinumab, a humanized monoclonal antibody targeting interleukin-13 (IL-13), in treating moderate-to-severe AD in a real-world setting, with a focus on different AD phenotypes.

Methods: An observational cohort of 30 adults treated with tralokinumab for ≥ 16 weeks was analyzed.

Atopic dermatitis (AD) is a common chronic inflammatory skin disorder globally. Crisaborole, a nonsteroidal topical phosphodiesterase 4 inhibitor (PDE4i), has been utilized in treating AD. Crisaborole regulates the production of inflammatory cytokines, which are usually overactive among AD patients.

Phosphodiesterase-4 (PDE4) is involved in the synthesis of inflammatory cytokines that mediate several chronic inflammatory disorders, including psoriasis and atopic dermatitis. In recent years, the therapeutic armamentarium in dermatology has expanded with the introduction of PDE4 inhibitors, both in oral and topical formulations. PDE4 inhibitors have gained increasing interest due to their remarkable safety record and ease of prescription, as evidenced by the recent influx of literature detailing its off-label uses.
