Association of erectile dysfunction with atopic dermatitis: a population-based case-control study.

INTRODUCTION Some studies have highlighted the high prevalence of erectile dysfunction (ED) in patients with dermatological diseases such as psoriasis, chronic hand eczema, and systemic sclerosis. However, to date, there is still no study that has explored the relationship between ED and atopic dermatitis (AD). AIM Using a population-based data set, this case-control study aimed to examine the association of ED with prior AD by comparing the risk of prior AD between patients with ED and matched controls in Taiwan. METHODS This study used administrative claims data from the Taiwan National Health Insurance program. We identified 3,997 patients with newly diagnosed ED as cases and randomly selected 19,985 subjects without a history of ED as controls. Conditional logistic regression was used to calculate the odds ratio (OR) and corresponding 95% confidence interval (CI) for previously diagnosed AD between cases and controls. MAIN OUTCOME MEASURE The prevalence and risk of having been previously diagnosed with AD between cases and controls were calculated. RESULTS Of the 23,982 sampled subjects, 1,758 (7.3%) had been previously diagnosed with AD; it was found among 425 (10.6%) cases and among 1,333 (6.7%) controls (P<0.001). Conditional logistic regression analysis demonstrated that cases were more likely to have prior AD than controls (OR=1.60, 95% CI=1.42-1.80, P<0.001) after adjusting for monthly income, geographic location, urbanization level, hypertension, diabetes, coronary heart disease, hyperlipidemia, obesity, and alcohol abuse/alcohol dependence syndrome. CONCLUSIONS There was an association between ED and prior AD. We suggest that clinicians should be more attentive to sexual complaints from patients with AD.
