    IntroductionThe aim of our study was to evaluate the influence of long-term insulin pump treatment (CSII) on the parameters of metabolic syndrome in insulin-resistant patients with poorly controlled type 2 diabetes mellitus.Patients And MethodsThirteen obese (BMI>30) patients (8 women, 5 men), average age 58.8+/-9.06 years, treated with an intensified insulin regimen with high doses of insulin (>0.8 IU/kg per 24 h) for at least 12 months were enrolled in the study. Prior to CSII treatment, all patients were reeducated regarding diabetes treatment and metabolic syndrome, and glycemic control parameters were assessed. Insulin resistance was evaluated with the hyperinsulinemic euglycemic clamp test. All tests were repeated after six months of CSII treatment. The Wilcoxon matched-pairs signed-rank test and Spearman's rank correlation coefficient were used for statistical evaluation. Results are presented as median (1st quartile; 3rd quartile).ResultsThere were no changes in long-term glycemic control during the course of CSII treatment: HbA1c prior to CSII 9.60 (8.95; 10.60) vs. after 6 months 9.80 (9.50; 10.20) %, BMI 33.0 (32.1; 34.2) vs. 32.9 (32.0; 34.5), total daily insulin dose 69.0 (65.0; 94.0) vs. 68.0 (58.9; 92.4) IU/24 h in observed patients. There was a statistically significant improvement in insulin resistance: M value 2.55 (1.92; 3.15) vs. 3.32 (2.23; 4.49) mg/kg per min (P<0.01), and improvement in atherosclerosis risk factors (blood coagulation and endothelial dysfunction): fibrinogen 3.44 (3.13; 3.86) vs. 3.24 (2.77; 3.38) g/l, factor VII 115 (101; 128) vs. 109 (93; 119)%, factor VIII 230 (148; 260) vs. 188 (126; 225)%, vWF:RiCo 162 (141; 193) vs. 128 (100; 132)%, PAI-1 39 (30; 44) vs. 30 (25; 36) AU/ml, thrombomodulin Ag 4.1 (3.7; 4.4) vs. 3.7 (3.45; 4.05) ng/ml (P<0.01).ConclusionsSix months of CSII treatment led to decrease in insulin resistance and improvement in parameters of lipid metabolism, blood coagulation and endothelial dysfunction independently of glycemic control and weight.
