[Assessment of quality of life illness in adult patients with atopic dermatitis].

Background: Atopic dermatitis (AD) is a disease with an impact on the patient's quality of life (QoL). Several tools have been designed to assess the clinical severity of the disease, such as the Eczema Area and Severity Index (EASI), while specific instruments have been created to assess QoL, such as the Dermatology Life Quality Index (DLQI) and the Quality of Life Index for Atopic Dermatitis (QoLIAD).

Objective: To define which tool is the best to assess the QoL condition of adult patients with AD in relation to the EASI.

Material And Methods: Patients with AD (> 18 years old) were selected who agreed to complete the DLQI and QoLIAD questionnaires, as well as to have a dermatologic examination reported according to the EASI. Three simple linear regression models were fitted in order to quantify the association between EASI with DLQI and QoLIAD. A value of p < 0.05 was considered statistically significant. The CV condition model with the highest pseudo R2 value was considered to have the strongest association with EASI.

Results: A total of 72 patients were included. Simple quantile regression models revealed a regression coefficient of 0.243 for DLQI (p = 0.002) and 0.252 for QoLIAD (p = 0.003). The pseudo R2 values were 0.15 for DLQI and 0.10 for QoLIAD, so DLQI had a higher correlation with EASI.

Conclusions: DLQI proved to be the best instrument to assess CV impairment in adult patients with AD.
