Pollution and climate extremes may raise atopic dermatitis risk in adults. New research links ATP signaling to immune response in melanoma, helping predict which patients respond to immunotherapy. Elevated risk for psoriasis was consistent across atopic dermatitis subgroups, including those without atopic comorbidities. The protective effect of dog exposure early in life was seen in both cohort groups. Adiposity may influence psoriasis through mechanisms separate from known genetic pathways. Neurosteroids may play a central role in itch linked to atopic dermatitis. Tiny particles in cow colostrum reduced eczema symptoms in mice, pointing to a potential new natural therapy. AI model uses smartphone images to objectively track eczema severity. Phase 3 trial shows ivarmacitinib is effective and safe for moderate to severe atopic dermatitis in teens and adults. Researchers identified the pathologic and clinical characteristics of patients who experience disease relapse. Study finds early lebrikizumab response in AD linked to lower inflammation—may guide personalized treatment plans. Treatment with the drug demonstrated lesion and pain control in moderate to severe disease. Symptomatic benefits of treatment on the severity of pustules, erythema, and scaling were observed. TLR9 gene variants may influence vitiligo risk, new research suggests innate immunity plays a key role. Elevated bilirubin levels may lower vitiligo risk, suggesting a protective role, new genetic study finds. Tofacitinib shows promising 6-month results for alopecia totalis and universalis, with notable hair regrowth and safety profi Topical JAK inhibitors show promise for vitiligo, but current evidence lacks strong statistical support, study finds. PEPITEM and its analogues show promise as steroid-free anti-inflammatory agents in psoriasis and immune cell regulation. Individuals with TSW had elevated levels of a form of vitamin B3, causing inflammation separate from eczema symptoms. Topical application of PEPITEM addressed systemic inflammation, suggesting therapeutic benefit beyond the skin.
