Diagnosis of smear-negative Pulmonary Tuberculosis in Kiffa hospital, Assaba, Mauritania

Abstract

Background In recent years, tuberculosis has been experiencing a renewal which appears to be linked to epidemiological, clinical and paraclinical factors. It is a real public health problem. Summary: There is a prospective study at Kiffa regional hospital from January 1st to December 31st, 2017, Objective: The goal was establish the real contribution of chest radiography to patient with respiratory infection diseases with a negative microscope smear. Results: We recruited 53 cases of pulmonary tuberculosis (79% of all TB cases). For Acid-Fast Bacilli (AFB) in sputum on direct examination and optical microscopy was negative in 52% of cases. The eight patients who accepted the HIV test, 6 were HIV positive. The sex ratio M/F was 1.7 and the average age of patients was 45 years old (range 15-80 years)The most common clinical signs were fever, sputum, chronic cough and chest pain. The radiological aspects of the negative tuberculosis were caves (34%), reticular or reticulonodular (26%), lymph nodes pulmonary hilum opacities nodular (23%), pleurisy (14%) and miliary (3%). In the lung lesion, parenchymal lung lesion were majority, it account for 64%, more of the lesions were located in the right upper lobe(49%). Conclusion: This approach provided a TB diagnostic tool in patients with pulmonary tuberculosis negative bascilloscopie. In hospital practice, the combination of simple clinical, and radiological symptoms as an aid in the diagnosis of TB. Some Similar studies are needed to improve diagnosis in patients from outpatient suspected TB.
