TAILIEUCHUNG - Bronchial Anthracosis and Pulmonary Tuberculosis

Bronchial anthracosis is defined as appearance of multiple dark anthracotic pigmentations on large airway mucosa with or without airway narrowing or obliteration. Since there has been vague and controversy regarding the relationship between bronchial anthracosis and pulmonary tuberculosis, we conducted this study to shed light on this matter. Materials and Methods: In this cross-sectional study, data was obtained from reviewing the files of 1,594 patients who underwent bronchoscopy in Afzalipour Hospital during 2003 to 2007. Those with dark pigmentation on their airways mucosa were considered as having bronchial anthracosis. During bronchoscopy, samples were collected from the airways in the form of bronchoalveolar lavage and then the. | ORIGINAL ARTICLE Tanaffos 2010 9 2 21-25 2010 NRITLD National Research Institute of Tuberculosis and Lung Disease Iran Bronchial Anthracosis and Pulmonary Tuberculosis Mitra Samareh Fekri 1 Mohammad Reza Lashkarizadeh 2 Amir Hossein Kardoost 1 Mostafa Shokoohi 3 1 Department of Pulmonary Medicine 2 Department of Surgery 3 Kerman Physiology Research Center Kerman University of Medical Sciences KERMAN-IRAN. ABSTRACT Background Bronchial anthracosis is defined as appearance of multiple dark anthracotic pigmentations on large airway mucosa with or without airway narrowing or obliteration. Since there has been vague and controversy regarding the relationship between bronchial anthracosis and pulmonary tuberculosis we conducted this study to shed light on this matter. Materials and Methods In this cross-sectional study data was obtained from reviewing the files of 1 594 patients who underwent bronchoscopy in Afzalipour Hospital during 2003 to 2007. Those with dark pigmentation on their airways mucosa were considered as having bronchial anthracosis. During bronchoscopy samples were collected from the airways in the form of bronchoalveolar lavage and then the smear and culture of these samples were examined for acid fast bacilli. Patients with both positive culture and smear and those with positive culture alone for acid fast bacilli were considered as having pulmonary tuberculosis. Results Of 1 594 cases studied in this research 333 had bronchial anthracosis out of which 158 were women. Risk of bronchial anthracosis was times less in men CI 95 p . In other words bronchial anthracosis had a significantly less prevalence among men. Also risk of tuberculosis in people with bronchial anthracosis was times more than that of healthy people CI 95 p . Conclusion This research revealed a significant correlation between bronchial anthracosis and pulmonary tuberculosis. Therefore performing necessary tests and follow-ups for .
