Type 1 plasminogen activator inhibitor as a common risk factor for cancer and ischaemic vascular disease: the EPICOR study
نویسندگان
چکیده
OBJECTIVES We examined the association of plasminogen activator inhibitor-1 (PAI-1) levels with colorectal cancer, breast cancer, acute coronary syndrome (ACS) and ischaemic stroke. DESIGN Nested case-cohort study. SETTING The European Prospective Investigation into Cancer and Nutrition-Italy cohort. PARTICIPANTS A centre-stratified random sample of 850 participants (286 men, 564 women) was selected as subcohort and compared with 303 colorectal cancers, 617 breast cancers, 688 ACS and 158 ischaemic strokes, in a mean follow-up of 9.11 years. MAIN OUTCOMES AND MEASURES Primary incident cases of colon cancer, breast cancer, ACS and ischaemic stroke. PAI-1 levels were measured in citrated plasma by ELISA. HR and 95% CI, adjusted by relevant confounders and stratified by centre, were estimated by a Cox regression model using Prentice method. RESULTS Individuals in the highest compared with the lowest quartile of PAI-1 had significantly increased risk of colorectal cancer (RR=2.28; 95% CI 1.46 to 3.55; P for trend<0.0012), breast cancer (HR=1.70; 95% CI 1.21 to 2.39; p<0.0055), ACS (HR=2.57; 95% CI 1.75 to 3.77; p<0.001) and ischaemic stroke (HR=2.27; 95% CI 1.28 to 4.03; p<0.0017), after adjustment for sex and age. Additional adjustment for disease-specific confounders, insulin or other metabolic variables did not modify the associations. Risk of colon cancer was stronger for men and for whole and distal colon localisation. Risk for breast cancer was stronger in postmenopausal women. CONCLUSIONS Our data provide the first evidence that elevated levels of PAI-1 are potential risk factors for colorectal and breast cancer and a common pathway for cancer and cardiovascular disease.

Serum Level of Plasminogen Activator Inhibitor Type-1 in Addicted Patients with Coronary Artery Disease
Background: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction with PAI-1 level. Opium addiction i...
متن کاملSignificance of raised plasma concentrations of tissue-type plasminogen activator and plasminogen activator inhibitor in patients at risk from ischaemic heart disease.
Tissue-type plasminogen activator (t-PA) is a familiar thrombolytic agent for myocardial infarction. It is perhaps natural, therefore, to think of endogenous t-PA as a "good thing" in terms of protection against coronary thrombosis or other consequences of atheroma. This view is supported by studies that showed a correlation between high concentrations of plasminogen activator inhibitor (PAI-1)...

Background: The Plasminogen Activator Inhibitor-1 gene 4G/5G (PAI-1 4G/5G) polymorphism has been suggestedto be associated with osteonecrosis of the femoral head (ONFH) susceptibility; however, the results are conflicting andinconclusive. We have carried out a comprehensive meta-analysis to derive a more precise estimation of the association.Methods: A comprehensive search in PubMed, EMBASE, Go...
