Sažetak
Type-1 diabetes mellitus (T1DM) is caused by autoimmune insulitis. There are evidences that pregnancy and n-3 fatty acids exhibit suppressive effect on human inflammatory system. Ninety pregnant women with T1DM were included in the prospective randomized placebo controlled clinical trial. Forty-seven of them were put on standard diabetic diet enriched with EPA and DHA twice a day (EPA 120 mg and DHA 616 mg ; Study group) and 43 pregnant diabetic women were on standard diabetic diet with placebo (Control group). Duration of T1DM in all participants was between 5 to 30 years. Blood samples were analyzed from all pregnant women for fasting C-peptide (FC- peptide), fasting plasma glucose (FPG) and HbA1c in each trimester throughout pregnancy and after delivery. Umbilical vein blood was analyzed for fetal C-peptide level, glucose concentration and insulin resistance. In the Study group FC-peptide concentration raised from 59.6±103.9 pmol/l in first trimester, to 67.7±101.3 pmol/l in the second trimester and to 95.1±152.7 pmol/l in the third trimester. Comparing the FC-peptide values during first and third trimester a statistically significant increase in third trimester was found (P<0.001). In the Control group FC-peptide concentration ranged from 41.7±91.6 pmol/l in the first trimester to 41.2±70.9 mmol/l in the second trimester while in the third trimester it reached 52.4±95.3 pmol/l. Comparing the FC-peptide values during first and third trimester the statistical difference was not significant. Combining of LC n-3 PUFAs and pregnancy yields immunological tolerance and stimulates the production of endogenous insulin in women with T1DM.
