Abstract:

Background: The present study aimed to determine and compare the frequency distribution of chest radiographic views in patients with smear positive and smear negative pulmonary tuberculosis (TB).
Methods: In this case-control study, 142  patients with pulmonary tuberculosis were carried-out by non-probable sampling method. We evaluated the demographic data, sputum acid-fast staining result and chest radiography of patients and recorded the results involving the region and the type of the lung involvement. Then, the collected data were analyzed and compaired between smear positive and smear negative cases using chi-square and p<=0.05 considered significant.
Results: The mean age of the patients was 46.46 ± 20.51; 60 patients (42.3%) were men and 82 (57.7%) were women.  53 patients (37.3%) were Iranian and 89 (62.7%) were Afghani.From 142 patients, 81 (57%) were smear positive and 61 (43%) were smear negative. The mean age, sex and nationality distribution were not different between smear positive and smear negative patients. There was not any significant difference between the region   and the type involvement in the two groups in radiographic results.
Conclusion: Based on the results of this study, there was no difference between smear positive and smear negative patients in terms of chest radiography findings.
