BACKGROUND: Poor sleep quality occurs in patients with psoriasis at rates nearly twice that of the general population. Chronic sleep impairment is an independent risk factor for the development of cardiovascular disease. Here, we examine the association between sleep quantity and history of myocardial infarction in patients with psoriasis. METHODS: This observational, cross-sectional study utilized data from the 2020 National Psoriasis Foundation Annual Survey. Effect estimates were obtained using a multivariate logistic regression model, which controlled for prespecified covariates. RESULTS: Based on data from 1405 individuals with psoriasis, our analysis demonstrated a significant association between sleep quantity and history of myocardial infarction: odds ratio (OR) 0.67 [95% confidence interval (CI) 0.49-0.92], p = 0.012. The association was not significantly influenced by psoriasis severity (OR 1.01, [95% CI 0.99-1.03], p = 0.38), comorbid psoriatic arthritis (OR 1.06, [95% CI 0.48-2.38], p = 0.88), sleep apnea, or other traditional risk factors for myocardial infarction. CONCLUSION: Our analyses indicate an association between sleep quantity and history of myocardial infarction in patients with psoriasis. For each hour increase in average nightly sleep, patients with psoriasis have a 33% decrease in the odds of having a history of myocardial infarction. The chief limitation of this study is its cross-sectional design limiting ascertainment of causality.

Psoriasis is an immune-mediated skin disease commonly treated with biologic therapies. While there are currently 12 different biologics approved for psoriasis, there still exists a challenging subset of patients who have tried and failed biologics from multiple classes. In this commentary, we discuss the research and advocacy-based efforts by the National Psoriasis Foundation (NPF) and academic collaborators to understand and better support multiple biologic failure (MBF) psoriasis patients. The NPF MBF registry will gather clinical and demographic information on MBF patients to improve therapeutic outcomes, while legislative efforts through NPF Capitol Hill Day aim to advance federal laws in support of all psoriasis patients, with a recent focus on access to biologic therapy. Together, these 2 efforts will improve the care for all people living with psoriasis, including those experiencing MBF.

BACKGROUND: Despite their impressive efficacy in phase 3 trials, biologic agents for psoriasis (PsO) may lose efficacy over time. The factors associated with loss of efficacy have yet to be fully elucidated. OBJECTIVE: We aimed to identify factors associated with PsO patients using multiple biologics in comparison to patients who used 1 biologic. We also reviewed the literature comparing the survival of different biologic agents for PsO. METHODS: We examined clinical data from 222 psoriasis patients at the University of California San Francisco, of whom 51 reported use of 3 or more biologics and of whom 171 reported use of only a single biologic agent at the time of enrollment into a research database from 2006-2020. This study was IRB-approved at UCSF (#10-02830) and all subjects provided written informed consent. We performed univariate and multivariate regression analysis to identify significant demographic features, clinical features, and co-morbidities associated with multi-biologic use. We performed a literature review of studies comparing psoriasis biologic survival at 1, 2, and 5 years and factors associated with single biologic failure. RESULTS: In univariate analysis, duration of PsO, initial presentation of PsO on the gluteal cleft, erythrodermic psoriasis, and acne were associated with using 3 or more biologics. In multivariate analysis, duration of PsO, erythrodermic psoriasis, and acne remained significant. Our review of biologic survival revealed differences according to biologic class. CONCLUSION: We identified novel factors associated with multi-biologic use in PsO. Further studies in this area are needed to achieve a precision medicine approach.
