Real-life experience in the effectiveness, impact on quality of life and safety of dupilumab treatment in patients with moderate to severe atopic dermatitis in the Czech Republic
Abstrakt
OBJECTIVES: The aim of the study was to assess the effectiveness and safety of dupilumab therapy in patients with moderate-to-severe atopic dermatitis (AD) in a real-life Czech bicentric cohort. METHODS: We retrospectively analysed 50 patients with moderate-to-severe AD treated with dupilumab in two centres in the Czech Republic.
Baseline characteristics, the Eczema Area and Severity Index (EASI) score and Dermatology Life Quality Index (DLQI) were collected at baseline and each 3 following months. The proportion of patients achieving EASI50, EASI75, EASI90 and EASI100 were analysed.
Levels of immunoglobulin E (IgE) were collected before and after 6 and 12 months of therapy. Adverse events were recorded as well.
RESULTS: Thirty-two men and 18 women with mean body mass index (BMI) of 25.7 were enrolled in our analysis. The mean age of the patients was 37.6 years and the mean time from diagnosis until the initiation of dupilumab therapy was 35.0 years.
After 4 months, EASI75 was achieved by 75.7%, out of which 40.5% achieved EASI90 and 10.8% achieved complete clearance. Improvement continued with time, and the proportion of patients with EASI90 increased to 71.4% at the 6th month and at the 12th month of therapy the EASI90 was 65.2%.
EASI100 was achieved by 14.3% and 13.0% at the 6th and 12th month, respectively. A marked reduction was observed in the DLQI and also in IgE levels.
EASI responses were independent of BMI. No new safety issues were identified.
Adverse events were experienced by 44% (22/50) of the patients and they were all mild in intensity. Conjunctivitis and herpes simplex virus infection were the most common adverse events.
CONCLUSION: Our results confirmed the effectiveness and safety of dupilumab in a real-life setting in adult patients with moderate-to-severe AD in the Czech Republic. Dupilumab was well-tolerated and resulted in a significant clinical improvement in combination with improvement of quality of life.
