Evaluation of Pulmonary Impairment by Spirometry in Post Pulmonary Tuberculosis Patients
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 5
Abstract
Background: Tuberculosis has been stated as a risk factor for development of COPD in the GOLD guidelines. It is important to know the relative burden of lung function impairment brought about by tuberculosis because there is a high prevalence of tuberculosis and smoking in the country Aim of the Study: Toanalyze the spirometric abnormalities in a cohort of post tuberculosis patients To know the factors associated with the spirometric abnormalities Study Method: The study was conducted in the Dept of Pulmonary Medicine, Govt Medical College, Kozhikode in the period between 2009 and 2013. An analysis of records maintained under RNTCP is made. All new sputum smear positive cases during the period 2002 to 2006who had completed 5 years after their treatment for smear positive tuberculosis were identified and called to the OPD. History, physical examination and investigations including chest X-ray, sputum AFB smear and spirometry was done in all patients. Results: A total of 82 patients were available for final analysis. The age of the patients ranged from 24 to 80 years and mean age was 51.29. 74 (90.2%) were males and 8 (9.8%) were females. At 5 years after treatment completion 61 (74.4%) were symptomatic and 21 (25.6%) were asymptomatic. Radiological sequelae were present in 54 (65.9%) patients.59 (72%) patients were smokers 23 (28%) were nonsmokers. Spirometry revealed obstructive pattern in 37 patients (45.1%), restrictive pattern in 21 patients (25.6%). it revealed a mixed pattern or normal results in 24 patients (29.3%). Conclusion: Abnormal spirometry was found in 58 (70%) patients. Obstructive pattern was the most common abnormality. Restrictive pattern was the main abnormality in nonsmokers. Presence of radiological sequelae correlated with the presence of spirometric abnormality. The obstructive pattern showed significant association with presence of radiologic sequelae,smoking and persistent chest symptoms after completion of ATT.
