BACKGROUND: Folate and vitamin Bare involved in metabolic reactions for combating oxidative stress. We measured erythrocyte folate and plasma vitamin Band compared these with blood antioxidants - erythrocyte glutathione (GSH), glutathione peroxidase (GPx), superoxide dismutase (SOD), and plasma vitamin C - and marker of lipid peroxidation, thiobarbituric acid reactive substance (TBARS), in chronic pancreatitis (CP) patients.
METHODS: One hundred and seventy-five CP patients (91 tropical, 84 alcoholic) and 113 healthy controls were recruited. Erythrocyte folate and plasma vitamin Bwere measured using microbiological assay, and antioxidant levels and erythrocyte TBARS by spectrophotometry.
RESULTS: Erythrocyte folate and plasma vitamin Bwere significantly lower in CP patients than controls (225.4± 9.13 vs. 380.38 ± 17.29 nmol/L, p<0.001 and 233.23± 10.4 vs. 338.84 ± 19.01 pmol/L, p<0.001), and in diabetic- vs. non-diabetic CP patients. Blood antioxidant levels were significantly lower and TBARS was higher in CP patients as compared to controls. Low folate level correlated with low GSH levels (r = 0.314, p<0.001). CP patients with low folate and vitamin Bhad low GSH and GPx levels as compared to patients with normal folate and vitamin Blevels. Low vitamin Blevel was associated with 3.24 (95% CI 1.11-9.46, p<0.05) fold increased risk of pancreatic insufficiency. Smoking was associated with 9.82 (95% confidence interval [CI] 3.3-29.22, p<0.05) fold increased risk of having low folate levels.
CONCLUSION: Low folate and vitamin Blevels were associated with increased oxidative stress in CP patients.
