Atopic dermatitis patients show increases in serum C-reactive

Atopic dermatitis (AD), the most common chronic inflammatory Background: skin disease, is evolving as a systemic disease, and associated systemic inflammation is possibly linked to increases in cardiovascular disease. We assessed levels of the inflammatory marker CRP in 59 patients Methods: with moderate-to-severe AD compared to matched healthy controls, and to determine correlation with skin disease severity. Clinical severity was measured using SCORing of Atopic Dermatitis (SCORAD) and body surface area (BSA). Control subjects (n=118), matched by age, gender, smoking status and ethnicity, were obtained from the National Health and Nutrition Survey (NHANES). AD patients had significantly increased serum CRP levels compared Results: to controls (0.7±1.0 vs. 0.4±0.7mg/dl; p=0.001). CRP levels were significantly correlated with both SCORAD (r=0.427, p=0.0008) and BSA (r=0.407, p=0.0015). IgE levels in AD were highly elevated (median 2903U/ml, IQR [234,10655]), but only weakly correlated with SCORAD (r=0.282, p=0.0427) and BSA (r=0.382, p=0.0052), but not with CRP levels. AD patients also showed increased LDH levels, but without significant correlations with disease severity (SCORAD, BSA) or CRP. Our study strongly supports CRP as a marker for disease Conclusions: severity in moderate-to-severe AD patients, further demonstrating its chronic systemic nature. 1* 2* 1 1
