Abstract: 

The present technology describes the use of two enzymes (angiotensin-converting enzyme and/or angiotensin-converting enzyme 2) as fecal biomarkers, using them or a composite of both to assess, diagnose or monitor inflammatory bowel disease, as well as a response to treatment and intestinal health. The invention includes the sequencing of the fecal enzymes, the production and use of target antibodies against them, and a kit based on the detection of those enzymes with the antibodies. 

Background: 

Nowadays, the diagnosis and monitoring of inflammatory bowel disease rely on patient interviews, routine clinical analysis and invasive procedures, like colonoscopies, biopsies and blood samples. Also, dysbiosis is emerging as a health imbalance. Recently, fecal biomarkers are emerging as a more convenient alternative.

Benefits: 
  • Non-invasive approach;
  • Easy sample collection;
  • Suitability across age ranges and health condition of the individual;
  • Comfort of the patient;
  • More reliable results (as stools are in direct contact with the intestinal mucosa, they are more prone to reflect the health/disease status of the intestinal mucosa/wall than a blood sample) 
Potential comercial use/applications: 

A kit for non-invasive fecal biomarker of inflammatory bowel disease and other pathophysiological conditions and for monitoring intestinal health.
