Abstract

Epidemiological studies have shown a strong association between dermatitis and stroke. Systemic corticosteroid, the mainstay treatment for dermatitis, could enhance the atherosclerotic process. Traditional Chinese Medicine (TCM) has been used for dermatitis to decrease the side effects of corticosteroid. However, the different stroke risk in dermatitis patients treated with systemic corticosteroid or TCM remains unclear. This study identified 235,220 dermatitis patients and same comorbidity matched subjects between 2000 and 2009 from database of NHRI in Taiwan. The two cohorts were followed until December 31, 2011. The primary outcome of interest was new diagnosis of stroke. The crude hazard ratio (HR) for future stroke among dermatitis patients treated with systemic corticosteroid was 1.40 (95% CI, 1.34–1.45; ) and TCM was 1.09 (95% CI, 1.05–1.13; ). The log-rank test showed a higher cumulative incidence of ischemic stroke in the patient treated with only systemic corticosteroid group than that treated with systemic corticosteroid and TCM, only TCM, and neither systemic corticosteroid nor TCM in the matched cohort during the follow-up period (). We demonstrated that patients treated with systemic corticosteroid had an increased risk of stroke and that the risk probably decreased by TCM treatment.
