Disorders of hemostasis and thrombosis


Clinical and translational research in hemostasis, thrombosis, transfusion medicine, and sickle cell disease


Clinical Studies/Trials in Hemostasis, Thrombosis and Sickle Cell Disease:
Dr. Konkle has several active federally-funded studies focusing on the clinical impact of hemostasis and thrombosis. These include 1) A feasibility study of low molecular weight heparin to prevent postpartum thrombosis in women at higher risk for venous thromboembolism (NHLBI R34), 2) A study to determine biomarkers predictive of heparin-induced thrombocytopenia in patients undergoing cardiac catheterization and cardiopulmonary bypass surgery (NIH RC1), 3) A cross sectional analysis of cardiovascular disease and complications of anticoagulant and antithrombotic therapy in men with moderate and severe hemophilia (CDC), and 4) A study of N-acetylcysteine in patients with sickle cell disease to evaluate safety and laboratory endpoints of hemolysis and changes in von Willebrand factor NHLBI RO1).

She has a long standing interest in laboratory assessment of bleeding and thrombotic disorders and in the development of new testing. She is co-leading a nationwide project to provide mutation analysis to patients with hemophilia, to assess next generation sequencing in this context, and to provide a repository for future research. She is evaluating laboratory assays for von Willebrand disease and hemophilia with aims to develop testing with improved correlation with bleeding phenotype, and to predict thrombotic risk postpartum.

She is involved in clinical trials of new therapies for hemophilia and von Willebrand disease, and studies of outcomes in hemophilia (HUGS).
