Abstract

Objective: Diseases due to environmental asbestos exposure is a serious health problem in Southeast of Turkey. The aim of our study was to show alterations of pulmonary Capillary Epithelial Permeability (CEP) in environmental asbestos exposure and investigate its correlation with High Resolution Computed Tomography (HRCT) findings. Materials and methods: Total of 47 cases having a history of asbestos usage and 22 healthy people not exposed to asbestos for control group were included to the study. HRCT and Tc-99m DTPA aerosol scintigraphy were performed to all cases. Scintigraphy was performed to control group. CEP as the percentage of decreasing activity per minute which is an index of pulmonary membrane permeability was calculated. Results: Pleural plaque was most frequently detected in HRCT. Mean CEP value of cases was found as significantly low compared with the control group (0.952-1.287 %/mn) (p=0.003). Mean CEP value of cases having no lesions in HRCT was found as significantly low compared with the control group (0.994-1.287 %/mn) (p=0.012). No significant difference was detected between the mean CEP values of cases having a lesion in HRCT and cases having no lesions (0.939-0.994 %/mn) (p=0.9), Mean CEP value of cases having interstitial fibrosis in HRCT was detected as significantly low compared with the control group (1.025-1.287 %/mn) (p=0.03). No significant difference was found between the mean CEP values of cases having interstitial fibrosis and cases not having (p=0.4). Conclusion: We found that the value of CEP decreases significantly in environmental asbestos exposure and is able to be effected before detectable radiological changes and it can be a noninvasive sensitive parameter to show early fibrosis. We think that studies of wider population may be useful to show whether CEP can be an early predictor of fibrosis.

Özet

Amaç: Çevresel asbest maruziyetine bağlı oluşan hastalıklar Güneydoğu Anadolu Bölgesinde önemli bir sağlık sorunudur. Çalışmamızda amacımız, çevresel asbest maruziyetinde oluşabilecek pulmoner kapiller epitelyal permeabilite (KEP) değişikliğini ve KEP değeri ile yüksek rezolüsyonlu bilgisayarlı tomografi (YRBT) bulguları arasındaki korelasyonu incelemektir. Gereç ve yöntem: Çalışmaya asbestli toprağı kullanma hikayesi olan toplam 47 olgu ile asbest maruziyeti olmayan 22 kontrol vakası alındı. Çalışma grubuna YRBT ve Tc-99m DTPA aerosol inhalasyon sintigrafısi çekildi. Kontrol grubuna ise Tc-99m DTPA aerosol sintigrafısi çekildi. Akciğer membran permeabilitesinin bir indeksi olan dakikalık aktivite azalma yüzdesini ifade eden KEP değeri hesaplandı. Bulgular: Plevral plak YRBT'de en sık saptanan lezyondu. Asbest maruziyeti olan olguların KEP ortalama değeri kontrol grubuna göre anlamlı düşük bulundu (0.952-1.287 %/dk) (p=0.003). YRBT'de lezyon saptanmayan asbest maruziyetli olguların ortalama KEP değeri kontrol grubuna göre anlamlı düşük bulundu (0.994-1.287 %/dk) (p=0.012). YRBT'de lezyon saptanan ve hiçbir lezyon saptanmayan çalışma grubu olgularının KEP değerleri arasında ise anlamlı fark saptanmadı (0.939-0.994 %/dk) (p=0.9). YRBT'de interstisyel fıbrozis saptanan çalışma grubunun KEP değeri kontrol grubuna göre anlamlı düşük saptandı (1.025-1.287 %/dk) (p=0.03). İnterstisyel fıbrozis saptanan çalışma grubunun KEP değeri, interstisyel fıbrozis saptanmayan çalışma grubuna göre ise anlamlı farklı bulunmadı (p=0.4). Sonuç: Çevresel asbest maruziyetinde KEP değerinin kontrol grubuna göre azaldığı görüldü. Radyolojik olarak herhangi bir değişiklik görülmeden önce KEP'in etkilenebileceği ve erken dönemdeki fıbrozisi göstermede noninvaziv hassas bir parametre olabileceği saptandı. Geniş serili çalışmalar ile KEP'in asbeste bağlı fıbrozisi göstermede erken bir prediktör olup olamayacağının gösterileceğini düşünmekteyiz.
