Abstract

The aim of the study was to measure alveolo-capillary membrane permeability through Tc99m-DTPA in diffuse interstitial lung diseases (DILD); to search the diagnostic value and to define its relations with findings of computerized tomography, spirometry, diffusion capacity (DLCO) as well as arterial blood gases (ABG). Twenty six patients (16 non-smoker, 10 non-smoker for at least three months) diagnosed DILD, those had no corticosteroid or immunosupressive treatment previously, were included in the study group. Sixteen non-smoker voluntary individuals with normal chest radiography and without any respiratory system complaint were selected as control group. Lung clearance was measured by using Tc99m-DTPA in both group. In DILD cases (1.92 ± 1.01% min-1), it was observed that clearence was significantly higher than control group (1.075 ± 0.3% min-1) (p< 0.001). There was not significant difference for arterial oxygen pressure, the gradient of alveoloarterial oxygen, forced expiratory volume in one second, forced vital capacity in groups with normal and abnormal clearence. A significantly negative correlation was found between lung diffusion capacity and clearence (p= 0.01). The velocity of the clearence, spirometry and ABC were similar in cases with different radiologie findings. Measurement of clearence is a non-invasive useful technique in diagnosis of interstitial lung pathologies. There was significant negative correlation between Tc99m-DTPA lung clearence and DLCO. In DILD, Tc99m-DTPA lung clearence did not change in non-smoker cases and cases who did not smoke at least for three months. In view of accelerated clearence, there was no difference for various radiology paterns.

Özet

Bu çalışmanın amacı, difüz İnterstisyel akciğer hastalıkları (DlAH)'nda alveolo-kapiller membran permeabilitesinin Tc99m-DTPA ile ölçülmesi, tanısal değerinin araştırılması ve bilgisayarlı tomografi (BT), spirometrik ölçümler, difüzyon kapasitesi (DLCO) ve arteriyel kan gazları (AKG) ile olan ilişkisinin araştırılması idi. Çalışma grubuna DiAH tanısı konulan, daha önce kortikosteroid veya immünsüpresif tedavi almamış, hiç sigara içmemiş (16 olgu) veya en az üç aydır sigara kullanmayan (10 olgu) 26 olgu ve kontrol grubuna sigara içmeyen, solunum sistemi yakınması olmayan, akciğer grafisi normal olan gönüllü 16 kişi alındı, iki grupta da Tc99m-DTPA kullanılarak akciğer klirensi ölçüldü. DlAH'li olgularda klirensin (%1.92 ± 1.01 dakika-1), kontrol grubu klirensine göre (%1.075 ± 0.3 dakika-1) anlamlı derecede artmış olduğu saptandı (p< 0.001). Arteriyel oksijen basıncı, alveolo-arteriyel oksijen gradienti, birinci saniye zorlu ekspiratuar akım, zorlu vital kapasite normal ve anormal klirensli olgularda değişiklik göstermedi. DLCO ve klirens arasında belirgin negatif korelasyon izlendi (p= 0.01). Klirens hızı, spirometri ve AKG farklı radyolojili olgularda benzer idi. Tc99m-DTPA ile akciğer klirensinin ölçümü, İnterstisyel akciğer patolojilerinin tanısında faydalı, invaziv olmayan bir tekniktir. Tc99m-DTPA akciğer kiirensi ile DLCO arasında belirgin negatif korelasyon söz konusudur. Tc99m-DTPA akciğer klirensi, hiç sigara içmemiş ve en az üç aydır sigara içmeyen DİAH'li olgular arasında farklılık göstermemektedir. Akciğer klirensinin hızlanmasında farklı radyolojik tutulumlar etkili olmamaktadır.
