Objective

To establish the association of the dynamic changes in carbohydrate, lipid metabolism parameters and blood pressure (BP) profile in patients with combined course of arterial hypertension (AH), type 2 diabetes mellitus (DM) and subclinical hypothyroidism (SH) and to determine the efficacy of the applied scheme. We examined 106 patients – 45 women and 61 men aged 45–55 years with AH stage II grade 2 and type 2 DM which were divided on SH presence into two groups: gr.1 – with SH which additionaly to the main antihypertensive scheme received levothyroxine (n = 47) and without SH (n = 59) – gr.2. Levothyroxine was administered in an individually selected dosage by titration in accordance with the obtained laboratory parameters.

Methods

BP profile, HOMA-insulin resistance (IR), glycated hemoglobin (HbA1c), lipid metabolism parameters (LDL-C, HDL, TG), thyroid-stimulating hormone (TSH) levels.

Results

Analysis of patients monitored during the year with multimorbid pathology – gr. 2 showed more expressed disorders of carbohydrate metabolism – fasting glucose, HbA1c, compared with similar indicators in gr.1, which demonstrates more significant metabolic changes, and subjectively indicates an increase in cardiovascular risk. Patients of gr. 2 are characterized by more pronounced manifestations of dyslipoproteinemia in the form of increased LDL-C (P<0.05) and hypertriglyceridemia and lower levels of HDL. In the dynamics of combined antihypertensive treatment in patients from gr. 1 and gr. 2, a sufficient antihypertensive effect was found, which was to achieve the target BP levels of 76.43 % and 69.27 % of those surveyed, respectively. Significant differences after 12 months of therapy were reached by the value of systolic BP in all examined groups (P<0.05). Diastolic BP was significantly reduced in all groups compared to the initial values (P <0.05). Administration of levothyroxine led to a significant reduction in proatherogenic lipids, in group 2, where LDL-C from (3.6 ± 0.33) mmol/l to (2.5 ± 0.27) mmol/l, P <0.05, and TG from (3.3 ± 0.44) mmol/l to (1.85 ± 0.31) mmol/l, P <0.05, whereas SH promotes the development and progression of atherosclerosis despite hypolipidemic therapy.

Conclusions

Additional administration of levothyroxine to the standard combined scheme in patients with AH, type 2 DM and SH improve lipid, carbohydrate metabolism and hemodynamics in the form of a significant reduction in dyslipidemia, normalization of fasting glucose levels and HbA1c which definitely reduces the risk of cardiovascular events in this category of patients.
