are there predictors of clinically significant thrombus formation in patients with gastroparesis and prolonged IV access?
Some patients with gastroparesis (GP) require sustained central intravenous access for hydration, medication and/or nutrition, leaving them at risk for venous thrombosis. We studied a group of 53 patients with gastroparesis for identifiable risk factors of clinically significant thrombosis. Patients requiring prolonged central IV access fell into two groups: those who had clinical incidence of IV catheter-related thrombosis confirmed radiologically (CLOT, n = 14), and those who did not form IV catheter thrombosis (NOCLOT, n = 39). We analyzed and compared clinical symptoms, serum/plasma coagulation studies, and autoimmune antibodies in the CLOT and NOCLOT groups. Patients in the CLOT group had statistically more Scl 70 antibodies than did the NOCLOT group, and another autoantibody, Ku 66, was found in higher titers in the NOCLOT group than the CLOT group. Other autoimmune and coagulation factors were not statistically different between the two groups, although a subgroup of CLOT patien
