Spirometric and radiographic profile of patients with pulmonary tuberculosis treated and cured at the Department of Pulmonology of Brazzaville University Hospital

Introduction Tuberculosis is a real public health problem in Congo. Pulmonary localization can lead to sequelae of respiratory functional repercussions. Objective Describe the spirometric and radiographic profile of patients treated with pulmonary tuberculosis treated and cured. Patients and methods This was a cross-sectional study that included 150 patients with previous pulmonary tuberculosis with positive microscopy treated and cured in the Pulmonary Department of Brazzaville University Hospital. In which we performed a functional exploration (Spirometry) and a chest X-ray. The study took place from 1st January 2016 to 31st August 2016. Results The spirometry performed in all patients was pathological in 68.67% (103 cases/150) of the cases. Among them 74.76% (77 cases/103) had a restrictive profile (FEV1/FVC > 70% and CVF < 80%), 9.71% (10 cases/103) an obstructive syndrome (FEV1/FVC ≤ 70% and CVF > 80%) and 15.53% (16 cases/103) a mixed syndrome (FVC < 80% and FEV1/FVC < 70%). Of the 150 chest radiographs performed, 120 or 80% were pathological; the degree of parenchymal stage III destruction represented 28.33%. There was a significant correlation between the degree of parenchymal destruction and the delay in treatment on the one hand and between the degree of parenchymal destruction and the different pulmonary volumes and volumes on the other hand. Conclusion The prevention of these respiratory functional disorders is based on the prophylaxis of tuberculosis on early diagnosis of the disease.
