Abstract
Background and objectives: Evaluation of patients included in the registry of biological/targeted therapy BIOREP in the Czech Republic. Methods: A retrospective evaluation of patients to date 31 December 2021 enrolled in the BIOREP registry was performed.
The aim of our study was to evaluate patients on biological/targeted treatment in the given period in individual categories and to analyze the population of patients with psoriasis, hidradenitis suppurativa and atopic dermatitis. Results: As of 31 December 2021, a total of 4,121 patients were registered in the BIOREP registry: 3,379 (82.0%) patients with psoriasis, 328 (8.0%) with hidradenitis, 403 (9.8%) with atopic dermatitis and 11 (0.3%) were treated off label with biological treatment.
Of the psoriasis group, 63.3% of patients were men. The average patient age at the end of 2021 was 52.1 years, the mean age at the time of diagnosis was 25.0 years, and the age at first biological/targeted treatment was 46.0 years.
In 2021, the average time from diagnosis to the introduction of biological treatment was 21.1 years, the average duration of biological/targeted treatment was 5.2 years. The comorbidities occurred in 70.4% of patients.
The most common disorder were metabolic/endocrine diseases (38.1%) and cardiovascular diseases (37.5%). From the individual comorbidities, hypertension (35.6%), dyslipidemia (26.7%) and diabetes mellitus (11.7%) were the most common.
More than 75% of patients were overweight or obese and 31.5% of patients were smokers. Psoriatic arthritis was observed in 34.5% of patients.
At the start of treatment and at the last visit, the mean PASI was 18.9 and 1.9, respectively and DLQI 16.4 and 1.6 respectively. In 2021, a total of 347 patients newly started treatment.
As of 31 December 2020, there were a total of 328 patients with hidradenitis suppurativa in the registry of men ages 44.8 years, 56.13% were men. The mean age at the time of diagnosis was 33.3 years and the age at first biological treatment was 42.7 years.
The average time from diagnosis to the start of the biological treatment was 9.5 years and patients were treated for an average of 2.1 years. In 2021, a total of 73 patients started the biological treatment.
At the end of 2021, a total of 281 patients were treated and the average duration of treatment was 2.1 years. At the end of 2021, there were a total of 403 patients with atopic dermatitis in the registry of mean age 38.5 years, 54.6% were men.
The mean age at the time of diagnosis was 5.1 years and the age at first biological treatment was 37.7 years. The average time from diagnosis to the start of the biological treatment was 32.6 years and patients were treated for an average of 1.1 years.
A total of 67.5% of patients had concomitant allergic rhinitis, 57.3% food allergy and 52.4% allergic asthma. Ocular comorbidities occurred in 29.5% of patients, the most common were atopic conjunctivitis (15.4%).
At the start of treatment and at the last visit, the mean EASI was 32.9 and 4.3, respectively and DLQI 18.5 and 3.7 respectively. In 2021, a total of 173 patients started the biological treatment.
At the end of 2021, a total of 382 patients were treated and the average duration of treatment was 1.1 years. Conclusion: BIOREP is the first registry of patients with psoriasis treated with biologics in Central and Eastern Europe.
Our results, when compared with European registries, show a comparable or higher prevalence of comorbidities, risk factors and a long period of inadequate treatment before starting biological therapy.
