Abstract

Aim: We aimed to evaluate the efficacy of mepolizumab on asthma exacerbations, blood eosinophils, oral steroid dependence, and asthma control.
Material and Method: This study is a clinical observational study created from real-life data obtained by retrospective analysis. Patients who were initiated subcutaneous mepolizumab at a dose of 100 mg every four weeks in our clinic and received treatment for at least 16 weeks were included in the study.
Result: Thirty-four patients with severe eosinophilic asthma were included in the study. We found that mepolizumab treatment resulted in a decrease in the number of asthma exacerbations, the need for maintenance oral corticosteroid, blood eosinophil counts, and improvement in lung functions and asthma control test scores in patients with severe eosinophilic asthma. At 6 months the rate of responders and super responders to mepolizumab treatment was 75% and 17.9%, respectively, and the overall response rate was 92.9% as a result. In the first year of treatment, the rate of super-responders increased to 58.3%, and the overall response rate was 91.7%. The rate of second-year responders and super-responders was 7.7% and 84.6%, respectively, and the overall response rate was 92.3%. At 3 years, the overall response rate had increased to 100%.
Conclusion: The results of our single-center study, in which we evaluated the results of mepolizumab treatment in patients with severe eosinophilic asthma, confirmed the clinical, hematological and functional findings published by previous studies in a real-life setting.

Mepolizumab ile tedavi edilen ağır eozinofilik astımlı hastalarda gerçek yaşam verilerinin değerlendirilmesi

Abstract

Amaç: Mepolizumabın astım alevlenmeleri, kan eozinofilleri, oral steroid bağımlılığı ve astım kontrolü üzerindeki etkinliğini değerlendirmeyi amaçladık.
Gereç ve Yöntem: Bu çalışma, retrospektif analiz ile elde edilen gerçek yaşam verilerinden oluşturulmuş klinik gözlemsel bir çalışmadır. Kliniğimizde dört haftada bir 100 mg deri altı mepolizumab başlanan ve en az 16 hafta tedavi gören hastalar çalışmaya alındı.
Bulgular: Ağır eozinofilik astımı olan 34 hasta çalışmaya dahil edildi. Ağır eozinofilik astımı olan hastalarda mepolizumab tedavisinin astım alevlenmelerinin sayısında, oral kortikosteroid idame ihtiyacında, kan eozinofil sayılarında ve akciğer fonksiyonlarında ve astım kontrol testi puanlarında iyileşme ile sonuçlandığını bulduk. 6 ayda mepolizumab tedavisine yanıt verenlerin ve süper yanıt verenlerin oranı sırasıyla %75 ve %17,9’du ve sonuç olarak genel yanıt oranı %92,9’du. Tedavinin ilk yılında, süper yanıt verenlerin oranı %58,3’e yükseldi ve genel yanıt oranı %91,7 oldu. İkinci yılda yanıt verenlerin ve süper yanıt verenlerin oranı sırasıyla %7,7 ve %84,6 ve genel yanıt oranı %92,3’tü. 3 yılda, genel yanıt oranı %100’e yükselmişti.
Sonuç: Ağır eozinofilik astımı olan hastalarda mepolizumab tedavisinin sonuçlarını değerlendirdiğimiz tek merkezli çalışmamızın sonuçları, gerçek yaşam ortamında önceki çalışmalarda yayınlanan klinik, hematolojik ve fonksiyonel bulguları doğruladı.
