This is a randomised study that compares different diagnostic approaches for diagnosing pulmonary tuberculosis in patients suspected of pulmonary tuberculosis in whom the three classic (non-induced) sputum samples didn't show tuberculous bacillus on direct examination.
The investigators compare the sensibility of induced sputum technique with an endoscopic approach (CT-scan followed by BAL and fluoroscopy-guided transbronchial biopsies and eventually sputum collection immediately after the bronchoscopy).
People in high risk population for tuberculosis undergoing screening by chest X-ray or symptomatic patients will be admitted to the hospital if their chest X-ray shows a suspicion of active tuberculosis.
According good clinical practice: (non-induced) sputum samples will be taken at admission and every following morning. If direct examination and PCR of the first three classic sputum samples are negative: patients will be randomised in two groups with a different diagnostic approach (induced sputum versus endoscopic approach) The aim of our study is to proof that a thoroughgoing endoscopic approach has a higher sensibility than an induced sputum in the diagnosis of pulmonary tuberculosis in patients with a high suspicion of active tuberculosis on the chest X-ray but with a negative direct examination and/or PCR on three consecutive normal sputum samples.
The investigators will include 154 patients (based on a statistical analysis for a hypothesis that the endoscopic approach has a sensibility that's twice the sensibility of the induced sputum).
- first arm: 2 consecutive induced sputum using an ultrasonic nebulizer.
- second arm: CT thorax to evaluate the exact anatomic localisation of the disease followed by fluoroscopy-guided bronchoscopy for BAL (bronchoalveolar lavage) and transbronchial biopsies. A sputum sample immediately after the endoscopy will be collected if possible.

Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)
The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.
MYCOBACTERIUM infections of the lung.
A single lung lesion that is characterized by a small round mass of tissue, usually less than 1 cm in diameter, and can be detected by chest radiography. A solitary pulmonary nodule can be associated with neoplasm, tuberculosis, cyst, or other anomalies in the lung, the CHEST WALL, or the PLEURA.
Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.
