Abstract
Aim : in women with Hashimoto's disease (HD) we studied the clinical and some molecular genetic characteristics of the lipid profile. Materials and Methods : Subjects for this study included 109 women with HD. The average age of 57.2 ± 7.8 years, disease duration 8.0 ± 6.4 years, menopause duration 6.4 ± 3.5 years. Control group consisted of 85 women of similar age without thyroid pathology. Clinical and anthropometric data was collected from all participants. Whole blood samples were drawn in the morning after an overnight fasting for the measurement of serum TSH, free thyroxine (FT4), anti-thyroid peroxidase antibody (TPO-Ab) levels, as well as lipid concentrations and glucose. In genetic research participated 441 women: 104 women with HD and 337 healthy women (control subjects). The genotype of the subjects for TaqIB polymorphism of CETP, rs320 (HindIII +/-) polymorphism of LPL, polymorphism of the coding portion of the gene APOE, rs2228314 (1784G/C) polymorphism of SREBF2 was analyzed by using polymerase chain reaction-restriction fragment length polymorphism. Results : Stratified by triglycerides (TG) level increased in subjects with HD and lowered levels of cholesterol of high density lipoproteins (HDL). Similar results were obtained when comparing the indexes of blood lipids in the group of women who have reached the level of TSH in the range of 0.4–2.5 mU/l on the background of ongoing substitution therapy with thyroid hormone. Not received the differences in the distribution of genotypes of the polymorphisms of the gene CETP Taq1B, rs320 LPL gene and ɛ2/ɛ3/ ɛ4 APOE gene, rs2228314 SREBF2 gene in the main and control groups. B1B1 TaqIB polymorphism of CETP of the main group had the higher levels of TG and BMI. ɛ3/ɛ4 APOE had the higher levels of total cholesterol, LDL cholesterol, cholesterol non-HDL in women with hypothyroidism. Conclusion : In women with compensated hypothyroidism TG levels above and below the level of HDL cholesterol compared to the control. Shown association of APOE and CETP gene with some lipids parameters.
