Abstract

Introduction and Aim: Emphysema, chronic bronchitis and bronchiectasis are the predominant phenotypes seen in chronic obstructive pulmonary disease (COPD) and may develop at different rates over time. The aim of the study was to investigate the effects of these three radiological phenotypes on survival in patients with COPD. Materials and Methods: The study was designed as retrospective and cross-sectional. Patients with stable COPD who applied between 2015 and 2019 and whose thorax high-resolution computed tomography were diagnosed with one of the three phenotypes radiologically were included in the study. A total of 90 male patients, 30 of whom had bronchiectasis, 30 had emphysema, and 30 had chronic bronchitis, were included. Age, body mass index, spirometry measurement values, blood tests, time of diagnosis, time of death, comorbidities and demographic data of the patients were recorded. Results: There was no statistical difference between the three groups in terms of age, baseline laboratory and spirometry values, except for FEV1/FVC. The FEV1/FVC ratio was found to be lower in emphysema-predominant COPD than in the other two phenotypes (p=0.023). While comorbidities such as hypertension, diabetes, and chronic heart failure were at a similar frequency between the three groups, coronary artery disease was found to be significantly higher in the emphysema group (p=0.030). The shortest survival was determined in chronic bronchitis and emphysema-predominant COPD, and the longest in the bronchiectasis-predominant COPD group (p=0.037). Conclusion: The phenotypes of chronic bronchitis, emphysema, and bronchiectasis in patients with COPD are similar in baseline values such as age, laboratory tests, body mass index, and spirometry measurements, excluding FEV1/FVC ratio. These three phenotypes are associated with a high rate of comorbidity, primarily cardiac. The shortest lifespan is in the chronic bronchitis and emphysema phenotype, and the longest in the bronchiectasis phenotype.

Çalışmada KOAH’lı hastalarda bu üç radyolojik fenotipin yaşam süresine etkisinin araştırılması amaçlandı. Gereç ve Yöntem: Çalışma retrospektif ve kesitsel olarak tasarlandı. 2015-2019 yılları içinde başvuran, stabil KOAH’lı olup toraks yüksek çözünürlüklü bilgisayarlı tomografi ile radyolojik olarak üç fenotipten birinin belirlendiği hastalar çalışmaya alındı. Otuzu bronşektazi, 30’u amfizem ve 30’u kronik bronşit olmak üzere toplam 90 erkek hasta dahil edildi. Hastaların yaş, vücut kitle indeksi, spirometrik ölçüm değerleri, kan testleri, tanı konulma zamanı, ölüm zamanı, komorbiditeleri ve demografik verileri kaydedildi. Bulgular: Üç grup arasında yaş, temel laboratuvar ve spirometrik değerlerde FEV1/FVC hariç istatistiksel olarak fark saptanmadı. Amfizem baskın KOAH’da FEV1/FVC oranı diğer iki fenotipe göre daha düşük bulundu (p=0,023). Üç grup arasında hipertansiyon, diyabet, kronik kalp yetmezliği gibi komorbiditeler benzer sıklıktayken, koroner arter hastalığı amfizem grubunda anlamlı şekilde yüksek bulundu (p=0,030). En kısa yaşam süresi kronik bronşit ve amfizem baskın KOAH’da, en uzun yaşam süresi bronşektazi baskın KOAH grubunda belirlendi (p=0.037). Sonuç: KOAH’lı hastalarda kronik bronşit, amfizem, bronşektazi fenotipleri arasında yaş, laboratuvar testleri, vücut kitle indeksi gibi temel değerlerde ve FEV1/FVC oranı hariç spirometrik ölçümler benzerdir düzeydedir. Bu üç fenotip başta kardiyak olmak üzere yüksek oranda komorbiditeyle birliktedir. En kısa yaşam süresi kronik bronşit ve amfizem fenotipinde, en uzun yaşam süresi bronşektazi fenotipindedir.
