Correlation between coagulation and inflammation state in patients with diabetes mellitus type 2 in relation to gender differences: Is there any impact of eight-week exercise training?

摘要

Background/Aim. The hypercoagulable state and inflammation state in diabetics has been widely studied by previous researchers, but there is a lack of research about a possible impact of exercise training on this relationship. The aim of this study was to assess and compare correlation between the coagulation and inflammation status in patients with type 2 diabetes mellitus taking into account the gender differences as well as an impact of the 8-week exercise training on the correlation coefficient and parameters of the inflammation and coagulation state. Methods. A total of 60 patients in stable clinical condition and well-regulated diabetic status passed through all phases of the study. The exercise training included the exercise program as interval training with estimated intensity uphill to 75% of a maximal heart rate in particular individual, 5 times a week for 8 weeks, and walking for 30 minutes with a speed of 5 km/h, 5 times a week for 8 weeks. Further fibrinolytic, coagulation and inflammatory parameters were analyzed before and after the study: D-dimer, von Willebrand factor (vWF), fibrinogen, high sensitivity CRP (hs-CRP), leukocytes, thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT) and coagulation factors: FII, FV, FVII and FX. Results. Our research showed a statistically significant reduction in the mean vWF levels after intervention both at the males (p 0.001) and females (p 0.001). According to a correlation analysis between hs-CRP and fibrinogen, there was a positive correlation as baseline both at the males (p 0.05, r = 0.492) and females (p 0.01, r = 0.516) which became weaker in the males (p 0.01, r = 0.449) and disappeared in the females (p 0.05, r = 0.059) after intervention. The correlation which existed as baseline in the males between D-dimer and either hs-CRP (p 0.01, r = 0.633) or fibrinogen (p 0.01, r = 0.673) as well as the correlation between hs-CRP and FII (p 0.01, r = 0.728), FV (p 0.05, r = 0.366), FVII (p 0.05, r = 0.373) coagulation as well as between D-dimer and FII (p 0.01, r = 0.851), FVII (p 0.05, r = 0.367)was absent in the females. Our research demonstrated a weakening correlations in the males after intervention between D-dimer and hs-CRP (p 0.05, r = 0.378), between hs-CRP and FII (p 0.01, r = 0.501), FV (p 0.05, r = 0.298), FVII (p 0.05, r = 0.351) as well as between D-dimer and FII (p 0.01, r = 0.759), and FVII (p 0.05, r = 0.296). The increase of the FX values (p 0.05) in the females after intervention suggested the possible antiinflammatory effect of exercise training. Conclusion. According to previous research, the higher levels of vWF was associated with a risk of cardiovascular disease in people with type 2 diabetes mellitus and vWF may be a risk factor unique to these populations. We demonstrated that the 8-week exercise training can significantly reduce the value of vWF in the males and females, suggesting a potential beneficial effect on the endothelial function parameters. Our research demonstrated a stronger correlation between the coagulation and inflammation parameters as baseline in the males than in the females with type 2 diabetes mellitus. According to our results, the 8-week exercise training lead to a weakening of the strength of correlation between the coagulation and inflammation parameters in the males and complete disappearance of this correlation in the females, suggesting a unique effect of exercise training that should be explored in future research.
