Abstract
Introduction The objective of this study is to identify the potential risk factors for progression from subclinical to clinical psoriatic arthritis (PsA). Methods A retrospective, longitudinal, case–control study was conducted at a single hospital, including 25 patients with clinically confirmed PsA in the case group and 137 controls without confirmed PsA. All patients in both groups had a medical history of subclinical PsA. Various baseline covariates were collected from all patients when they had a status of subclinical PsA. Univariate, multivariate, stratified, and interaction analyses were employed to identify potential risk factors of transiting to clinical PsA from subclinical PsA. Results In multivariate logistic regression analysis, older age (OR 10.15, 95% CI 2.79–36.91, p = 0.00), alcohol drinking (OR 3.43, 95% CI 1.17–10.12, p = 0.03), elevated high-sensitivity C-reactive protein (hs-CRP) (OR 1.05, 95% CI 1.01–1.09, p = 0.03) were identified as risk factors for transition from subclinical to clinical PsA. Stratified and logistic regression analyses suggest a significant interaction between age and fatty liver. For patients aged less than 45 years old, the association between fatty liver and clinical PsA was statistically significant. Conclusions Older age, alcohol drinking, elevated hs-CRP, and the presence of fatty liver at less than 45 years old appear to increase the risk of transition from subclinical to clinical PsA. These findings call for a need to manage these risk factors.Keywords
