Ross E. Petty is a Canadian pediatric rheumatologist. He is a professor emeritus in the Department of Pediatrics at the University of British Columbia and a pediatric rheumatologist at BC Children’s Hospital in Vancouver, Canada. He established Canada’s first formal pediatric rheumatology program at the University of Manitoba in 1976, and three years later, he founded a similar program at the University of British Columbia.

In 2006, he was appointed a member of the Order of Canada for his contribution within Canada and around the world to improving the lives of children and youth with rheumatic diseases. In 2012, he was awarded a Queen Elizabeth II Diamond Jubilee medal.

Early life and education

Petty was born in Bresaylor, Saskatchewan, and grew up in Paynton, Saskatchewan. He graduated from the College of Medicine of the University of Saskatchewan in 196.Renowned CoM alum a game-changer in pediatric arthritis research https://medicine.usask.ca/news/2015/renowned-com-alum-a-game-changer-in-pediatric-arthritis-research.php. After finishing his medical internship in Saskatoon, Petty moved to Ann Arbor, Michigan, where he completed his rheumatology training under the mentorship of Drs. Jim Cassidy and Donita Sullivan at the University of Michigan.Rosenberg, A. M. Pediatric Rheumatologist, Dr. Ross Petty, Retiring: A Tribute. The journal of the Canadian Rheumatology Association: CRA Journal 2005, Volume 15. He went on to earn a PhD in immunology from the University of London. His thesis was titled The significance of antibody affinity in immune complex disease.Theses.

Career In 1976, Petty returned to Canada and established the first formal pediatric rheumatology program at the University of Manitoba. In 1979, he started a similar program at the University of British Columbia.

Petty has combined laboratory and clinical research during his career. He studied the significance of factor VIII related antigen in juvenile dermatomyositis. In addition, he studied the relationship between juvenile idiopathic arthritis and uveitis to antinuclear antibodies (ANA), discovering that ANAs were highly expressed during the onset of the disease.

With colleagues, he demonstrated the relationship of IgA deficiency in childhood rheumatic diseases, the influence of maternal anti-IgA antibodies on the occurrence of IgA deficiency in the offspring. He and colleagues first described the association of HLA-A2 with juvenile idiopathic arthritis.Oen K, Petty RE, Schroeder ML. An association between HLA-A2 and juvenile rheumatoid arthritis in girls. J Rheumatol. 1982;9(6):916-920. Along with Alan Rosenberg, he described the syndrome of seronegativity, enthesitis and arthritis (SEA syndrome), its relationship to HLA-B27, and the development of ankylosing spondylitis.Rosenberg AM, Petty RE. A syndrome of seronegative enthesopathy and arthropathy in children. Arthritis Rheum. 1982;25(9):1041-1047. These findings are now included in the juvenile idiopathic arthritis classification, proposed by the International League of Associations for Rheumatology.Martini, A.; Ravelli, A.; Avcin, T.; Beresford, M. W.; Burgos-Vargas, R.; Cuttica, R.; Ilowite, N. T.; Khubchandani, R.; Laxer, R. M.; Lovell, D. J.; Petty, R. E.; Wallace, C. A.; Wulffraat, N. M.; Pistorio, A.; Ruperto, N.

Petty has contributed more than 225 original research papers and book chapters in medical and scientific journals.Petty, Ross E., Taunton R. Southwood, Prudence Manners, John Baum, David N.

He has co-authored every edition of the Textbook of Pediatric Rheumatology, a pediatric rheumatology reference book.Petty, R. E.; Laxer, R. M.; Lindsley, C.; Wedderburn, L. Textbook of Pediatric Rheumatology, 7th Edition.; Elsevier, 2016. https://doi.org/10.1016/C2012-0-00349-3. Petty chaired the International League of Associations for Rheumatology working group to define a new classification system and nomenclature for juvenile idiopathic arthritis and its subtypes.Tucker, L.
