Research Interests:


Dr. Gunning's current research emphasis involves the study of bleeding diathesis specifically related to platelet dysfunction. He has evaluated patients with prolonged bleeding times and/or a history of bleeding including individuals that bruise easily and women with menorrhagia for more than 20 years. When tested for von Willebrand disease, these individuals are usually found to have normal aggregation responses or have a slight abnormality in response to epinephrine but not to ristocetin and are therefore, often a diagnostic enigma. His research utilizes a transmission electron microscope and computer analysis of platelets obtained from peripheral blood to determine the number and volume of delta granules (dense bodies) that contain important substances used for the effective coagulation of blood. Dr. Gunning has a number of collaborators throughout the country and the preliminary results of these studies suggests that delta granule storage pool deficiencies (δ-SPD) may be a significant etiology of bleeding diathesis, especially in the case of menorrhagia. In addition, he has discovered a significant correlation with postural orthostatic tachycardia syndrome (a type of syncope) and δ-SPD. He has a number of exciting and ongoing investigations including a study of platelets and pregnancy of which preliminary results were recently presented in Amsterdam at the XXIV Congress of the International Society on Thrombosis and Haemostasis in July, 2013.
