Chronic spontaneous urticaria (CSU) is considered in a subset of patients to be an autoimmune disorder. Interleukin(IL)-17, IL-31, and IL-33 are involved in some immune response. The aim of this study was to quantify plasma IL-17, IL-31, and IL-33 levels in CSU patients and to examine their relationships with disease severity. Plasma IL-17, IL-31, and IL-33 concentration were measured in 51 CSU patients and 20 healthy subjects (HCs). Plasma IL-17 (P < 0.001), IL-31 (P < 0.001), and IL-33 (P < 0.001) concentrations were significantly higher in CSU patients when compared with those of HCs. Concerning UAS7, severe group of CSU patients had significantly higher IL-17 levels than the moderate and mild groups (P = 0.028 and 0.007, respectively), and significantly higher IL-33 concentrations than the mild group (P = 0.026). Regarding only pruritus, severe group of patients had significantly higher IL-31 levels than the mild group (P = 0.003). The IL-33 levels in the total IgE positive group were significantly higher than that of negative group (P = 0.010). Our results showed higher plasma levels of IL-17, IL-31, and IL-33 among CSU patients which may highlight a functional role of these cytokines in the pathogenesis of CSU.
Introduction: Depression and anxiety are common among people with rosacea. However, the exact magnitude of the prevalence rate and odds ratios (ORs) for depression and anxiety, respectively, in rosacea patients is unclear, and no systematic review or meta-analysis of published data has yet been performed. We therefore performed as systematic review and metaanalysis to determine the prevalence rates and ORs for depression and anxiety in rosacea patients.Methods: We performed a systematic search of the PubMed, Embase and Medline databases for all observational studies published up to October 2020 that reported the prevalence rates and ORs for depression and anxiety in patients with rosacea. The primary outcome measures were prevalence rates and ORs for depression and anxiety in patients with rosacea. Heterogeneity across studies was assessed with the I 2 statistic. Sources of heterogeneity were explored through subgroup and meta-regression analyses. Results: A total of 14 studies involving 14,134,021 patients with rosacea were included in the systematic review and meta-analysis. The pooled prevalence of depression was 19.6% (95% confidence interval [CI] 15.0-24.3%) and that of anxiety was 15.6% (95% CI 11.8-19.3%). The prevalence of depression and anxiety was significantly lower in studies using clinical criteria to diagnose depression and anxiety (9.2 and 10.2%, respectively) than in those studies using screening tools (26.2% [P \ 0.01] and 22.7% [P = 0.03], respectively). The methodological quality of the included studies greatly contributed to the heterogeneity. Patients with rosacea were more likely to experience depression (OR 2.21, 95% CI 1.79-2.72) and anxiety (OR 2.31, 95% CI 1.56-3.44) than healthy controls. Conclusions: This systematic review and metaanalysis indicates that patients with rosacea are at a higher risk of experiencing depression and anxiety. More efforts are warranted to recognize R. Dai and BJ. Lin contributed equally to this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
