Abstract
Background and objectives: The evaluation of patients with atopic dermatitis in the BIOREP registry in the Czech Republic. Methods: A retrospective evaluation of patients with atopic dermatitis treated with dupilumab enrolled in the BIOREP registry was performed to date 21st May 2021.
Results: A total of 219 patients with atopic dermatitis were registered in the BIOREP registry, 53.9% were men and 46.1% were women. The average patient age was 39.5 years and 38.4 years at the start of biological treatment.
The mean time from diagnosis to the initiation of biological treatment was 33.8 years. The most common comorbidities were allergic rhinitis in 67.1% of patients, food allergies in 56.6% and allergic asthma in 53.0% of patients.
Eye involvement was observed in 29.2% of patients. From the other evaluated comorbidities, at least one occurred in more than half of the analyzed patients (53.4%), the most common disorders were metabolic/endocrine (19.6%), cardiovascular (15.1%), and psychiatric diseases (6.8%).
At the start of treatment, the mean EASI was 33.2 and DLQI was 19.2. Patients are treated with dupilumab for an average of 10.3 months.
The 50% improvement in EASI was achieved by 95.7% of patients after 3 months of treatment, 98.3% after 6 months and 100% after 12 and 18 months of treatment. At the same time, the 75% improvement in EASI was achieved by 68.3%; 93.4%; 93.8% and 97.0% of patients, respectively.
During the treatment there was a significant improvement in the quality of life of patients, after 3 months of treatment the DLQI value decreased from the original 19.2 to 4.9. After 6 and 18 months of treatment, the value further decreased to 3.5 and 1.9 respectively.
Conclusion: BIOREP, as one of the oldest registries for biological/targeted therapy in dermatology, included patients with atopic dermatitis (BIOREP-AD) in 2020. The presented data complete the lacking information from real clinical practice and confirm the long duration of atopic dermatitis with the negative impact on a quality of life, the frequent association with comorbidities, the long period of previous insufficient treatment and the successful use of dupilumab.
