BACKGROUND: Oxidative stress could be a major contributing factor to the tissue injury that characterize inflammatory bowel disease (IBD). Homocysteine (HCY) could cause oxidative damage to the colon tissue in ulcerative colitis (UC) patients, melatonin (MLT) supplementation could reduce oxidative damage that caused by HCY in vitro and in vivo. In this study, we aimed to determine the levels of plasma HCY and MLT simultaneously in UC patients.
METHODS: Collected the clinical data of 112 UC patients and 110 healthy controls (HC). The levels of plasma HCY and MLT were detected by HPLC-FD method. The levels of plasma folate, vitamin B(12) (VitB(12)) were detected by ELISA method.
RESULTS: The levels of plasma HCY in UC patients were significantly higher than that in HC (11.27±7.26 μmol/L vs. 8.19±4.81 μmol/L, P=0.000). The levels of plasma MLT in UC patients were significantly lower than that in HC (49.06±31.40 pg/ml vs. 64.28±41.16 pg/ml, P=0.008). The levels of plasma folate and VitB(12) in UC patients were lower than that in HC (7.64±1.95 nmol/L vs. 9.14±1.23 nmol/L, 108.64±32.22 pmol/L vs. 112.64±33.33 pmol/L, P<0.05). The levels of plasma HCY and MLT in UC patients were not correlated with either the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) or the disease activity, localization and duration of UC (P>0.05). The change of increasing levels of plasma MLT but decreasing levels of plasma HCY was shown in UC patients, however, the association between the levels of plasma MLT and HCY were not statistically significant (P>0.05).
CONCLUSIONS: The levels of plasma HCY were increased whereas the levels of plasma MLT were decreased in UC patients.
