Abstract Patients with inflammatory bowel disease (IBD)have increased plasma n3 polyunsaturated fatty acids(PUFAs), which in ulcerative colitis (UC) patientspersists six months after colectomy, suggesting aprimary abnormality in fatty acid (FA) metabolism inIBD. This finding needed to be confirmed in a largerseries of UC long-term colectomized patients. We aimedto assess the plasma FA pattern in UC colectomized patients with either Brooke's ileostomy (UC-BI)or ileal pouch anal anastomosis (UC-IPAA) and themucosal FA pattern in the ileal reservoir of the UC-IPAApatients. Plasma FAs were assessed in 63 UC colectomized patients (31 with BI and 32 with IPAA) and 30controls. In 26 UC-IPAA (8 with pouchitis and 18 withoutpouchitis) and in 13 healthy controls gut mucosal FAswere also investigated. FAs were detected by capillary column gas-liquid chromatography.Increased levels of saturated fatty acids (SFAs) anddecreased percentages of monounsaturated fatty acids(MUFAs) were observed in both groups of patients. There were no changes in plasma n3 and n6 PUFAs. Themucosal FA pattern of the ileal reservoir consisted ofincreased long-chain PUFAs, specially n6 PUFA, and adecrease of their essential precursors. High percentages of SFAs and low percentages of MUFAs were alsoseen. The plasma FA profile previously described in IBDis not observed long-term after colectomy in UC,suggesting that it is related with the presence of inflamed intestine. High concentrations of SFAsand decreased percentages of MUFAs might represent earlyevents in disturbed FA metabolism in IBD. The changes inFAs of the ileal reservoir, which closely resemble those found in human and experimentalIBD, probably represent a common pattern of intestinalinflammation.
