Abstract

Study objectives: To compare the early bronchodilator responses of salbutamol (S), ipratropium bromide (IB), and the combination of salbutamol and ipratropium bromide (S-IB) on spirometric reversibility testing and to determine their role in the differential diagnosis in patients with asthma or COPD. Design: A prospective, randomized, single blind trial. Methods: The effects of S, IB, and S-IB on baseline spirometric parameters were evaluated in 47 patients with stable asthma and 32 patients with stable COPD at 30th minutes in three separate test days after the washout periods. Absolute increments ($\Delta$) of FVC, FEV1, MMEF, PEFR and change as a percentage of prebronchodilator value (% initial) were recorded and compared both between patient groups and drugs. Number of the reversibility positive patients according to ATS criteria were evaluated for each drug. Results: All spirometric parameters in asthmatic patients were significantly higher than COPD patients at basaline and 30 min in three separate test days. $\Delta$ and % initial values of FEV1, $\Delta$ and % initial values of MMEF after the S and S-IB inhalations were significantly higher than IB in asthmatic patients. No significant difference was detected among drugs in COPD patients. Average $\Delta$MMEF values of all drugs in asthma patients were significantly higher than those in COPD patients. FEV1 % initial and FVC % initial values of IB were significantly higher than S and S-IB in COPD patients. As for the ratio of reversibility positive patients in COPD group, there was no significant difference between the study drugs. However, S-IB seemed to be superior in asthma group for detecting reversibility positive patients. Conclusions: IB failed to identify spirometric reversibility in asthmatic patients. Therefore,beta2 agonist or combination of beta2 agonist-anticholinergic agent should be used on early reversibility test for the differantial diagnosis of asthma and COPD.

Özet

Amaç: Astım ve KOAH'lı olgularda salbutamol (S), ipratropium bromür (İB), ile salbutamol ve ipratropium bromür (S-İB) inhalasyonuyla ortaya çıkan erken bronkodilatör yanıtları ve ayırıcı tanıya katkılarını karşılaştırmak. Tasarım: İleriye yönelik, rastgele yöntemli, tek kör bir çalışma. Yöntem: Stabil astımlı 47, stabil KOAH'lı 31 olguya, arınma periyotları bırakılarak ve her test gününde farklı ilaç (S, İB veya S-İB) kullanılarak 3 ayrı test gününde bronkodilatörlü solunum fonksiyon testi uygulandı. FVC, FEV1, MMEF ve PEFR değerlerinde, 30. dakikadaki değişiklikler mutlak değer ($\Delta$) ve prebronkodilatör değerin yüzde olarak değişkenliği (% başlangıç) açısından değerlendirildi, ilaçlar ve hasta grupları arasında karşılaştırıldı. ATS ölçütlerine göre reversibilitesi pozitif olgu sayısı her ilaç için saptandı. Sonuçlar: Olguların 3 ayrı test gününe ait bazal ve 30. dakikada ölçülen spirometrik parametrelerdeki tüm değerler, astım grubunda KOAH grubuna göre anlamlı düzeyde yüksek bulundu. Astım grubunda S ve İB-S ile 30. dakikada sağlanan FEV1 ve MMEF'e ait $\Delta$ ve % başlangıç değerlerinin, İB'e göre anlamlı düzeyde yüksek olduğu saptandı. KOAH grubunda ise tüm parametrelerin $\Delta$ ve % başlangıç değerlerinde ilaçlar arasında anlamlı fark saptanmadı. Astım ve KOAH grupları karşılaştırıldığında, İB ile sağlanan FEV1 ve FVC'ye ait % başlangıç oranlarının KOAH grubunda, S, İB ve S-İB ile oluşan $\Delta$MMEF'nin astım grubunda anlamlı yüksek olduğu saptandı. KOAH grubunda, reversibilitesi pozitif olgu oranlarında ilaçlar arasında fark yokken, astım grubunda en iyi sonucun S-İB ile alındığı dikkati çekti. Yorum: İB, astımlı olgularda reversibiliteyi yansıtmakta yetersiz kalmaktadır. Bu nedenle astım- KOAH ayırıcı tanısında erken reversibilite testinde beta2-agonist ya da beta2-agonist-antikolinerjik kombinasyonu kullanılmalıdır.
