Assessing atopic dermatitis severity in children from Georgia: the correlation of inflammatory blood markers to the Eczema Area and severity Index

Atopic dermatitis (AD) is a chronic inflammatory skin condition prevalent among children worldwide. Systemic inflammation is a key factor in its pathophysiology. Correlating blood markers with Eczema Area and Severity Index (EASI) can reveal information about the severity and activity of the disorder, allowing for more focused treatment. A retrospective analysis was conducted on 22 patients aged 3 months to 18 years. Blood parameters, such as Eosinophil Relative Count (ERC), Neutrophil/Lymphocyte Ratio (NLR), Eosinophil/Lymphocyte Ratio (ELR), and Basophil/Lymphocyte Ratio (BLR), were correlated with the Eczema Area and Severity Index (EASI). A strong positive correlation was observed between EASI scores and ERC (r = 0.69, p < 0.001) and with ELR (r = 0.71, p < 0.001). No statistical significance was seen between EASI scores and the NLR (r = 0.2059, p = 0.3578) and BLR (r = 0.1026, p = 0.6494). No significant association was found between age and EASI scores (r = -0.0351, p = 0.8767). ERC and ELR have the potential to serve as objective blood markers for assessing AD severity. However, more research in pediatric populations with a larger sample size is needed to establish a conclusive association for clinical practice.
