CRP and Sepsis: This makes them a potentially suitable biomedical predictor of small bowel ischemia.7 Kittaka, in a clinical study of 37 patients diagnosed with small bowel obstruction, concluded the I-FABP level is a useful marker for discriminating between strangulated small bowel obstruction and simple small bowel obstruction.7 Using a prospective observational study of fifty patients with severe sepsis, Zhu found the IFABP concentrations in all patients were significantly increased.8 In addition, C-reactive protein (CRP) is an inflammation marker, confirmed by many studies.
