Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Determine the diagnostic accuracy for pulmonary tuberculosis in adults of the E-Nose in Venezuela.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Tuberculosis (TB) Receiver Operating Curve (ROC) Common Terminology Criteria for Adverse Effects (CTCAE)

The aim of the study is to determine the diagnostic utility of the device 'Electronic Nose' for Pulmonary Tuberculosis. Prospective, Open, Three - Arm Controlled trial Study. Validation of the E-nose in urban settings to estimate the diagnostic accuracy of the E-nose using exhaled air in patients with Pulmonary TB in adults.

The patients who qualified for the study, according to the inclusion criteria, after consenting, will be guided through and oriented survey for risk factors, then a complete physical exam, and after that, the patient will breathe for 5 minutes trough the device, which stores the patient information, that later will be download to a computer and will be send to the server's manufacturer company, in Netherlands.

During and after the use of the device, we determine the adverse effects of the intervention, according to the CTCEA.

The researchers use the sputum culture, which is the gold standard, to determine the diagnostic utility of the test. And, will compare the results with other tests currently perform as the regular diagnostic routine, such as Chest X-ray, sputum smear, and symptom based diagnosis.

The patients in the experimental group are invited to come during the treatment phase, and will be asses the progress of the treatment, as well as another use of the device, at 5, 15, 30, 60 days after initiation of treatment, and will be compared the results of the device, with symptoms, x-ray changes, improvement of anthropometric findings, to determine the utility of the device to measure the response to treatment.

Patient Registries will be keep in an electronic database, as well as handwriting history, with the backup copy in the records of the hospital in which the patient was admitted.

auditoriae will be realised by the Ethics Comite in different time frames.
