Core Tip

Core tip: An altered gut microbiota is usually responsible for a reduction of short chain fatty acids (SCFAs) concentration. In this study, we analyse through gas-chromatography coupled with mass spectrometry the fecal SCFAs’ concentration in patients with various gut diseases [celiac disease (CD), adenomatous polyposis (AP) and colorectal cancer (CRC)]. Altought the small sample size of study does not allow us to reach definitive conclusions, our findings suggest the existence of a fecal SCFAs fingerprint in patients with CRC amd AP distinguishable from healthy controls. On the contrary, no differences between celiac patients and healthy controls was observed.
