Một số đặc điểm dịch tễ, lâm sàng và cận lâm sàng của bệnh nhân viêm da cơ địa trẻ em tại Bệnh viện Da liễu Trung ương

Abstract

Objective: This study aims to describe epidemiology, clinical, subclinical of 2- to 12-year-old children diagnosed with atopic dermatitis at National Hospital of Dermatology and Venereology.
Subject and method: This descriptive cross-sectional study was conducted on 160 children aged 2 to 12 years diagnosed with atopic dermatitis at the National Hospital of Dermatology and Venereology from September 2022 to August 2023. Result: There were 78 males (48.8%) and 82 females (51.2%). Mean age ( ± SD years) was 6.44 ± 3.09. The age group with the largest proportion was 2-5 years old (44.4%), followed by the 6-9 year old group (36.3%), and the 10-12 year old group (19.3%). The rate of onset of atopic dermatitis before age 5 was 65%, after age 5 was 35%. 47.5% of patients had moderate disease, the number of patients with mild disease accounted for 28.7% and the number of patients with severe disease accounted for the lowest rate of 23.8%. 12.5% children with atopic dermatitis were noted to have a history of allergies. Among 106 patients tested for peripheral blood smear test, 34.9% of patients had an increased eosinophil index. There was a statistically signiicant association between the severity of atopic dermatitis and the blood eosinophil index. Conclusion: Atopic dermatitis tends to have an early onset before age 5, with an equal male/female ratio. The group of patients with moderate disease accounts for the highest proportion. The eosinophil index of children with atopic dermatitis tends to increase and is closely related to the severity of the disease in children with atopic dermatitis.
