简要总结

The purpose of this proposal is clinical validation of an electrochemical biochip for rapid pathogen identification and antibiotic susceptibility determination.

详细描述

Point-of-care identification of pathogens and determination of antibiotic susceptibility will significantly improve the clinical management of urinary tract infection. We have previously developed a biochip based on microfabrication technology capable of rapid detection of pathogens. The specific objectives of the current proposal are: 1) Determination of microbial constituents in spinal cord injury (SCI) patients and development of additional species-specific probes against these pathogens; 2) Development of a rapid antibiotic susceptibility and molecular pyuria assay using the electrochemical biochip; and 3) Clinical validation of the biochip as a diagnostic test for urinary tract infection.

Within a single protocol, two non-interventional studies were conducted at different time points to achieve the aforementioned objectives. Sensitivity and specificity of the electrochemical biosensor based assay was demonstrated in each study.

主要结局

Clinical Validation of Biosensor Assays Used for Pathogen Identification and Antimicrobial Susceptibility Testing in Patients at Risk of Urinary Tract Infections.

时间窗: Up to 1.5 years

Study 1: Multiplex pathogen identification using biosensor based assay. We recruited 116 participants yielding 109 urine samples suitable for analysis and comparison between biosensor assays and standard urine culture. Biosensor based assays were used to detect multiple pathogens in the urine samples. Study 2: Antimicrobial susceptibility testing using biosensor based assay. We recruited 222 participants yielding 252 urine samples. Corresponding biosensor and clinical microbiology culture data was available for 215 samples. 73% (157) of these samples contained bacteria. Biosensor based antimicrobial susceptibility test, in concert with pathogen identification assay was directly performed on these samples.
