Abstract

Background

Inflammation is a prominent clinical manifestation in type 2 diabetes mellitus (T2DM) patients, often associated with insulin resistance, metabolic dysregulation, and other complications.

Aim of the study

The present study has been designed to check the serum levels of PAR-1 and correlate with various clinical manifestations and inflammatory cytokines levels in type 2 diabetic subjects.

Material and Methods

The study population was divided into two groups, healthy volunteers (n = 15): normal glycated hemoglobin (HbA1c) (4.26 ± 0.55) and type 2 diabetic subjects (n = 30): HbA1c levels (7.80 ± 2.41). The serum levels of PAR-1 (ELISA method) were studied in both groups and correlated with demographic parameters age, weight, body mass index (BMI), and conventional inflammation biomarkers like C-reactive protein (CRP), interleukin 6 (IL-6), interleukin 8 (IL-8), and tumour necrosis factor-alpha (TNF-α).

Results

The demographic variables including the body weight (77.38 ± 10.00 vs. controls 55.26 ± 6.99), BMI (29.39 ± 3.61 vs. controls 25.25 ± 4.01), glycemic index HbA1c (7.80 ± 2.41 vs. controls 4.26 ± 0.55) were found to be statistically increased in T2DM subjects than the healthy control group. The levels of various inflammatory biomarkers and PAR-1 were significantly elevated in T2DM groups in comparison to healthy volunteers. The univariate and multivariate regression analysis revealed that elevated PAR-1 levels positively correlated with increased body weight, BMI, HbA1c, and inflammatory cytokines.

Conclusion

Our findings indicate that the elevated serum PAR-1 levels serve as an independent predictor of inflammation in T2DM subjects and might have prognostic value for determining T2DM progression.
