Dr. Gordon Sussman

Dr. Sussman is a Professor of Medicine at the University of Toronto in the Division of Allergy and Clinical Immunology at St. Michaels Hospital.

A major focus of his earlier research was natural rubber latex allergy. Dr. Sussman recognized and reported one of the first cases of latex allergy, and did research to decrease and help eliminate latex allergy which was an epidemic in the mid-1980s.

He continues to study chronic spontaneous (idiopathic) urticaria, which causes significant morbidity affecting the quality of life of many patients. Dr. Sussman, Leznoff, and Jose were among the first to point out that chronic hives were not related to food allergies but was autoimmune. He completed early studies in real life on the use of omalizumab in the treatment of CSU a game changing treatment for this condition.

He has done seminal research studies in hereditary angioedema and peanut anaphylaxis, which has led to novel treatments for these conditions.

His current research interests include cannabis related allergy. He was one of the first to recognize early case reports and the clinical manifestations of allergic reactions. He continues to work on allergen characterization allowing us to better understand the potential food cross reactivity.
