    Abstract:
    BACKGROUND: Gelsolin is an actin-binding protein with several cellular functions including anti-apoptosis and is reported to have an anti-inflammatory effect. Apoptosis of keratinocytes has been implicated as a key mechanism of atopic dermatitis (AD). OBJECTIVE: We aimed to determine plasma gelsolin (pGSN) levels in children with atopic dermatitis (AD). METHOD: The diagnosis of AD was made according to Hanifin and Rajka criteria. The disease severity was scored by objective SCORAD index by the same allergist. Skin prick testing (SPT), total IgE levels, and eosinophil counts were analyzed. The pGSN levels were determined using ELISA technique. RESULTS: Children aged between 0.5 and 3.0 years were included in the study. The children with AD (AD; n=84) were analyzed in two groups according to the presence (AD+/Atopy+; n=54) or absence of SPT positivity (AD+/Atopy-; n=30). The comparisons were made with a healthy control group matched for age and sex (n=81). The median (interquartile range) of pGSN levels in AD+/A+, AD+/A- and control groups were 267μg/ml (236-368), 293 (240-498) and 547 (361-695), respectively (p<0.001). The difference between the control group and AD sub-groups remained significant after Bonferroni correction (p<0.001). Correlation analysis failed to reach significance with the disease severity total IgE levels and eosinophil counts. CONCLUSION: This is the first study investigating the association of pGSN levels with AD and disease severity. pGSN levels decreased in AD. These findings suggest that gelsolin may have a role in the disease process in AD patients.
