Nosocomial Transmission of MDR-TB in Bucharest Romania


Brief description of study

Single-center, observational, prospective cohort study including patients hospitalized on the multidrug-resistant tuberculosis ward at Marius Nasta Institute.

The increasing rates of multidrug-resistant (MDR) tuberculosis (TB) are causing great concern. The current study that will be conducted at the Marius Nasta Institute, one of two nationwide excellence treatment centers for MDR-TB in Romania, is aiming to prospectively investigate the population structure of patients with MDR-TB admitted for treatment and the M. tuberculosis strains isolated from these patients. Transmission of MDR- strains of Mycobacterium tuberculosis among patients hospitalized there will be also ascertained. Additionally biomarkers for treatment response during the course of the tuberculosis therapy will be evaluated.

The study will be conducted in a co-operation between the Marius Nasta Institute and the German Center for Infection Research (DZIF).

Detailed Study Description

Single-center, observational, prospective cohort study including all patients hospitalized on the MDR-TB ward at Marius Nasta Institute.

An estimated 100 patients with MDR-TB consecutively admitted for treatment at the MNI will be assessed for eligibility as study participants. All potential participants will be asked to provide information on demographic, epidemiological and clinical characteristics as well as prior treatment and disease history. Microbiological data, treatment and adverse events data will also be recorded. The data is expected to supplement the existing body of knowledge about patients with MDR-TB from the region.

In order to characterize M. tuberculosis strains, sputum samples will be collected from the participants upon admission to the MDR-TB ward and after 3 months of therapy. Additionally, subsequent samples identified as being positive after prior culture conversion will also undergo testing. Key examinations on these samples include drug susceptibility testing on solid media and molecular typing. If samples originating from the same patient show discordance, whole genome sequencing will be performed to allow strain comparison between the actual patient strain and those isolated from other patients to identify potential nosocomial transmission. The location on ward of patients as well as their activities will also be recorded in the scope of identifying possible routes of transmission.

Blood and urine samples will be collected at specific time points during the study and further assessed in order to identify candidate biomarkers that are potentially correlated with response to anti-tuberculosis therapy.

All data generated from this study will be collected on standardized study forms and entered in a password-secured database.
