A Blinded, Cross-sectional, Diagnostic Evaluation Study Performed in Pulmonary TB Suspects at the TB Dispensary for Sector 4 of the Marius-Nasta-Institute in Bucharest, Romania
The diagnosis of tuberculosis (TB) and especially the detection of drug resistance of tuberculosis mycobacteria can be time consuming and costly. New and rapid diagnostic tests are needed to improve early case detection and correct initiation of treatment.
In the planned cross-sectional diagnostic evaluation study the investigators are aiming for the assessment of several new TB diagnostics (e.g. new AID strip assays and TrDNA assay in urine) in TB suspects who are presenting themselves to the pulmonary ambulance (TB dispensary for sector 4) at the Marius Nasta Institute (MNI). The study will be conducted in a co-operation between the MNI and the German Center for Infection Research (DZIF).
Studienübersicht
Detaillierte Beschreibung
Up to 400 TB suspects will be consecutively screened for their eligibility for participation in the study. In those who are eligible (according to the criteria listed above) to participate, 2 sputum samples and one urine will be collected for standard diagnostic testing for TB in sputum (smear, Line Probe Assays and culture methods, as defined in the national guidelines) and for the evaluation of the new assays; one blood sample will be collected for analysis of lipoprotein profiles in serum of TB patients. Further, a HIV test and a clinical examination will be performed in all study subjects. Information on risk factors for TB disease (co-morbidities such as diabetes mellitus, co-medication such as steroids and risk behaviour such as smoking) will be also documented.
All TB tests results and data which are generated in the study will be collected on standardized study forms and entered in a password-secured data base. TB tests results will be also shared with the medical staff treating the patients who are participating in the study.
One follow up visit will be performed after 8 weeks in order to evaluate the clinical progress of the participants, either on TB treatment (if TB was confirmed) or alternative therapy, in participants who were not diagnosed with TB.
The isolated TB strains will be sent to the Research Center Borstel in Germany for evaluation through sequencing and phenotypic methods. The remnants of collected samples will be stored in the National TB Laboratory for future evaluations of new tests.
