T2MR PCR Detection of ESKAPE Pathogens in Patients With Pyogenic Spondylodiscitis and Infective Endocarditis

Charles University, Czech Republic50 enrolled

Overview

Our prospective observational study focuses on the rapid detection of etiologic agents of pyogenic spondylodiscitis and infective endocarditis using the T2 Bacteria Panel (T2Biosystems). This diagnostic method combines polymerase chain reaction (PCR) and T2 magnetic resonance for detection of bacterial DNA from whole blood samples. It detects six pathogens known by the acronym ESKAPE (E. coli, S. aureus, K. pneumoniae, A. baumannii, P. aeruginosa, and E. faecium). In recent years, similar studies using the Bacteria Panel and Candida Panel have been performed in patients with bloodstream infections, leaving us with optimistic results.The aim of this study is to verify whether T2B can identify the etiologic agents of localized infections, specifically spondylodiscitis and endocarditis, with better sensitivity and specificity and shorter time to result compared to conventional diagnostics from blood culture. Rapid detection of pathogen may reduce time to targeted pathogen-specific antibiotic therapy and subsequently improve outcomes, shorten the treatment and contribute to slowing the development of antibiotic resistance.

Outcomes

Primary Outcomes

Sensitivity and Specificity of the T2 Bacteria Panel

Sensitivity and specificity of the T2 Bacteria Panel for ESKAPE pathogens direct detection in patients investigated for suspected pyogenic vertebral infection and/or infective endocarditis, compared with conventional blood culture and/or other relevant biological samples culture .

Time frame: 3 years

Expected treatment outcomes in patients diagnosed by T2 Bacteria Panel

T2 Bacteria Panel is expected to shorten the time to result compared to conventional methods. Rapid detection of the bacteria followed by early pathogen-specific antibiotic therapy should improve the outcomes of patients with spondylodiscitis and infective endocarditis, e.g. mortality, morbidity and length of treatment.

Time frame: 4 years

Secondary Outcomes

Diagnostic utility of T2 Bacteria Panel in other localized infections

Patients with other localized infections (other than spine or endocardium infections) who were tested with T2 Bacteria Panel before their diagnosis was assessed, will be excluded from the study. They will be separately evaluated to find out if T2MR diagnostics is useful also in other localised infections (besides of spine infection and endocarditis).
