Abstract

Celiac disease (CD) is a risk factor for venous thromboembolism (VTE) and stroke, but the mechanisms are unclear. Continuous measurement of thrombin generation in plasma is a feasible way to detect hypercoagulable changes. The aim of this pilot study was to investigate thrombin generation in pediatric patients with CD compared with pediatric controls. Plasma samples were collected from 19 pediatric patients with CD and 20 healthy controls. In each patient diagnosed as having CD, thrombin generation was determined twice by means of calibrated automated thrombography. The first measurement was undertaken when CD was diagnosed; the second measurement was undertaken after normalization of their IgA antitissue transglutaminase antibody (tTG-Ab) titers following a gluten-free diet. In the controls, measurement for TTG-Ab and thrombin generation was undertaken once during recruitment. Patients with CD at diagnosis showed a significantly shorter lag time compared with controls (P < 0.001) and a shorter time-to-peak compared with controls (P < 0.02). These differences were no longer detectable after normalization of TTG-Ab values. The overall amount of generated thrombin, represented by the endogenous thrombin potential (ETP), showed no...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
