Background: Psoriasis is a disease that often requires prolonged systemic treatment. It is important to determine the safety of available therapies. There is currently little insight into sex‐specific differences in the safety of systemic psoriasis therapies. Objectives: To examine the real‐world, long‐term safety of systemic psoriasis therapies with sex stratification in drug‐related adverse events (ADRs). Methods: Ten‐year data from adults with moderate‐to‐severe psoriasis requiring systemic treatment (conventional systemic therapies [CST], biologics) were obtained from the Swiss psoriasis registry (SDNTT). ADRs were categorized according to the international terminology Medical Dictionary for Regulatory Activities (MedDRA). Safety was assessed by calculating event rates per 100 patient‐years (PY). We used descriptive statistics for patient and disease characteristics, and binomial and t‐tests to compare treatment groups and sex. Results: In total, 791 patients (290 females) were included with a mean age of 46 years. 358 (45%) received CSTs and 433 (55%) biologics; both groups had similar baseline characteristics except for more joint involvement in patients using biologics (26.86% vs. 14.8%, p < 0.0001). CSTs were associated with a 2.2‐fold higher ADR rate (40.43/100 PY vs. 18.22/100 PY, p < 0.0001) and an 8.0‐fold higher drug‐related discontinuation rate than biologics (0.16/PY vs. 0.02/PY, p < 0.0001). Trends showed non‐significant higher serious adverse event rates per 100 PY for biologics (8.19, CI 6.87–9.68) compared to CSTs (7.08, CI 5.39–9.13) (p = 0.3922). Sex stratification revealed a significantly higher overall ADR rate for all treatments in females (1.8‐fold for CSTs [57.30/100 PY vs. 31.69/100 PY] and 2.0‐fold for biologics [27.36/100 PY vs. 13.9/100 PY], p < 0.0001), and drug‐related discontinuation rates for most CSTs in females. Conclusion: Females were associated with a significantly higher rate of ADRs and drug‐related discontinuation rates. Sex stratification should be taken into consideration when designing studies in the patient‐tailored management of psoriasis. [ABSTRACT FROM AUTHOR]

Background: Cutaneous melanoma (CM) is the leading cause of skin cancer mortality with associated high healthcare costs. Up-to-date reporting of epidemiological trends for CM is required to project future trends, assess the burden of disease and aid evaluation of new diagnostic, therapeutic and preventative strategies., Objectives: To describe the trends in CM mortality, incidence, mortality-to-incidence indices (MIIs) and disability-adjusted life years (DALYs) over the last three decades., Methods: A population-based cross-sectional study of the Global Burden of Disease (GBD) database between 1990 and 2019 was performed. Nineteen high-income countries with similar health expenditure and classified as having high-quality mortality data including the United Kingdom, the United States, Australia and selected European Union countries were included. Annual age-standardized incidence rates (ASIRs), age-standardized death rates (ASDRs) and DALYs for each country were extracted. Mortality-to-incidence indexes were calculated by dividing the ASDR by the ASIR. Trends were described using Joinpoint regression analysis., Results: Almost all countries demonstrated increasing ASDR in males over the observation period with greatest percentage increase in Greece (+87%), and there was greater heterogeneity between countries in females. CM mortality was greater for males than females in all countries. Most recent Joinpoint analysis shows significantly decreasing mortality in all countries except the United Kingdom (+0.5% males between 2007 and 2019, +0.1% females between 2002 and 2019). Incidence rates increased in all countries, with evidence of plateau from 2015 onwards. While MIIs cannot be used as a proxy for survival, statistically significant decreases in MII were observed in all countries. Overall, DALYs remained static., Conclusions: Over the past 30 years, CM mortality and incidence has increased in most EU15+ countries. There is evidence that in recent years, CM mortality is decreasing. The burden of disease as assessed using DALYs has remained mostly unchanged. Future work should not solely focus on expensive innovative therapies, but also on optimizing primary prevention., (© 2025 European Academy of Dermatology and Venereology.)
