As the state of hyperfibrinogenemia in diabetes patients occurs due to hyperglycemia which also activates the coagulative cascade ultimately stimulating hepatic fibrinogen synthesis and thus increases clotting factors and PAI-1 levels in the blood. Therefore, in present study our aim is to correlate between type of diabetes and plasma fibrinogen level and plasminogen activator inhibitor-1. This cross sectional study was conducted at Baqai Medical University (BMU) with the collaboration of Baqai Institute of Diabetology and Endocrinology, Karachi. Data was collected from 161 subjects, out of which 51 were control and 55 were subjects in each type 1 diabetes, type 2 diabetes simultaneously. Anthropometric measurements included measurement of weight, height, BMI and blood pressure which were done for each participant. Blood sugar levels and glycated hemoglobin, lipid profile, PAI-1 and fibrinogen were measured in cases and controls. Out of 161 subjects, 80 (49.7%) were male and 81 (50.3%) were female with mean age of 37.75±1.25 years. Fibrinogen level was significantly decreased in healthy subjects as compared to type 1 and type 2 diabetes subjects P-value<0.0001, however no significant difference was observed in fibrinogen level of type 1 diabetes subjects and type 2 diabetes subjects. Plasminogen activator inhibitor-1 of type 2 diabetes subjects was significantly increased as compared to type 1 diabetes subjects (P-value<0.05) but not significantly different to healthy subjects (P-value>0.05). Since, fibrinogen and plasminogen activator inhibitor type 1 was increased in diabetes patients this predisposed them to increased risk of coronary artery disease, our study further supports the clinical observation that diabetes is a thrombophillic condition.
