Study Notes
Alopecia Areata Study
- Quality of Life Improvement: Patients saw a visible improvement in their quality of life scores as measured by the Dermatology Life Quality Index (DLQI) at baseline and after 12 and 24 weeks of therapy, with statistically significant differences between groups (P < .0001).
- Limitations: Limitations of the study include the small size of the cohort, the lack of a placebo-controlled arm, the duration of the study was only short term, and the patients had relatively young age.
- Additional Information: Further evaluation in larger cohorts is necessary to evaluate the safety and efficacy of upadacitinib compared to other Janus Kinase (JAK) inhibitors.
- Funding Disclosure: The research received no funding.
- There study showed no conflicts of interest
Solar Urticaria Study
- SU is a rare photodermatosis with cutaneous mast cell degranulation after exposure to specific wavelengths of that solar electromagnetic radiation.
- Clinical signs include recurrent wheals and/or angioedema, and treatments often involve photoprotection and antihistamines.
- Analysis included 854 SU cases from 23 observational case series across 12 countries, with all skin phototypes represented
- Mean age of SU onset was 30.6 years (standard deviation 19.8) with a female predominance of 63.7%.
- Symptom onset was rapid, with 94.8% developing symptoms in under 15 minutes after sun exposure.
- Common symptoms were pruritus or burning which was 87.4%.
- Erythema or wheals developed in 81.4% of cases.
- Presentations such as erythema alone at (10.8%) or angioedema in (2.4%) were infrequent.
- Systemic symptoms were uncommon at (4.4%), and there were no deaths recorded
- Common treatments were H1-antihistamines (reported in 74.0% of cases) and phototherapy (35.7%), and omalizumab (2.1%)
- Analysis of 371 cases showed that 35.3% had complete disease resolution within 5 years of disease onset.
- The most common triggering wavebands were visible light only (29.3%) and combinations of UVA and visible light (24.9%)
Tumor-Infiltrating Lymphocytes Study
- TIL Status: Indicates that TIL status on primary melanoma biopsy samples do not associate with cutaneous or non-cutaneous immune-related adverse event (cirAE/irAE) development.
- Multivariable Analysis: Multivariable regression analysis did not identify any statistically significant associations between TIL status and cirAE/irAE development or severity.
- TILs in Melanoma Patients In melanoma patients, the presence of TILs at the primary biopsy showed the trend towards decreased later incidence of vitiligo (odds ratio: 0.21, 95% CI: 0.04-1.22, P = 0.081).
- TIL Status in Patients: Among patients with melanoma with cirAEs (n = 123, median age: 66, 33.3% female), 4 (3.3%) had brisk TIL, 98 (79.7%) had non-brisk TIL, and 21 (17.1%) had absent TIL. In the non-cirAE group (n = 87, median age: 63, 26.4% female), 2 (2.3%) had brisk TIL, 65 (74.7%) had non-brisk TIL, and 20 (23.0%) had absent TIL
