A STUDY TO KNOW THE PATTERN OF PULMONARY FUNCTION IMPAIRMENTS IN CURED PULMONARY TUBERCULOSIS CASES
Journal of Evolution of Medical and Dental Sciences
BACKGROUND India is the highest TB burden country in the world and patients with treated TB may remain lifelong sufferers of disabling sequelae. In cured pulmonary tuberculosis patients, many survivors develop into pulmonary sequelae that are characterized by bronchial and parenchymal structural changes, including bronchovascular distortion, bronchiectasis, emphysematous changes, and fibrotic bands. Structural changes lead to obstructive, restrictive, or mixed patterns of impaired pulmonary
... aired pulmonary function. Objective-This study was designed to analyse the pattern of pulmonary function abnormalities using spirometry with cured pulmonary tuberculosis (PTB) patients. . The patients of old treated pulmonary tuberculosis, presented with complaint of dyspnoea, were picked up from out-patient and in-patients section of the hospital at random. These patients were further divided into group A and group B. RESULTS Seventy-eight patients with cured pulmonary tuberculosis were enrolled during the study period. There were 53 males (67.9 %) and 25 (32 %) females. The mean age among males and females study population were 46.5 and 41.5 years respectively. The mean duration of anti-tuberculosis treatment was 12.5 months (range: 6-38 Months). Dyspnoea was associated in all the cases. Majority of the patients in both groups, belongs to MMRC grade 2 & 3. The airflow obstruction was found in 50%, followed by mixed defect (37.1 %) and restriction in 12.8 % cases. CONCLUSION The present study highlighted that most common pulmonary impairments were obstruction, followed by mixed and restrictive pattern.
