C-reactive protein, fibrinogen, prothrombin time and international normalized ratio levels as indicators of chronic inflammation in patients with metabolic syndrome

Aims: Although it has been stated in studies conducted in patients with metabolic syndrome (MetS) that elevated serum fibrinogen and C-Reactive Protein (CRP) may be due to chronic inflammation, sufficient studies have not been conducted on International normalized ratio (INR) and prothrombin time (PT). The aim of this study is to examine the fibrinogen, INR and PT levels of patients with MetS and to investigate the relationship between these parameters and MetS components. Methods: A total of 56 patients, 19 males and 37 females were included in our study who applied to the Internal Medicine outpatient clinic of Ondokuz Mayıs University Faculty of Medicine and met the MetS diagnostic criteria. The control group consists of a total of 64 people, 35 men and 29 women, who have at least one of the MetS criteria and do not have a chronic disease. Fasting blood glucose, total cholesterol (Total-C), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine, thyroid stimulating hormone (TSH), PT, INR and fibrinogen levels were examined from the available samples. Data were compared between healthy and patient groups. Results: As a result of our study, it was determined that the CRP level was significantly higher in the patient group (p<0.01). The average fibrinogen level was calculated as 3.56 g/l in the patient group and 2.95 g/l in the control group, and a significant difference was detected when the two groups were compared (p<0.001). The average PT value was 13.1 in the patient group and 12.04 in the control group and a significant difference was detected between both groups (p<0.001). The average INR level was 1.14 in the patient group and 1.04 in the control group and a significant difference was detected between both groups (p<0.001). Conclusion: MetS is associated with high CRP. In patients with MetS, PT, INR and fibrinogen levels are also high. In the follow-up and treatment of patients with MetS, the presence of chronic inflammation and factors affecting the coagulation system should be taken into consideration.
