The Division of Immunology, Allergy and Rheumatology at The University of Cincinnati was established in 1965 by the Department of Internal Medicine and provides a program of teaching for medical and postgraduate students, patient care for inpatients and outpatients, and a broad research program in rheumatic, allergic and general immunological diseases.

Currently there are 20 full-time, part-time and volunteer physicians and basic scientists engaged in these activities. Referral, diagnostic and treatment clinics have been established at all the major hospitals of the Medical Center. There is active collaboration with the departments of epidemiology and emergency medicine, pediatric rheumatology and pediatric allergy.

The division is one of the nation's Arthritis, Rheumatism, and Aging Medical Information System (ARAMIS) disease database centers. It is also a collaborating clinic of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Cooperative Systematic Study in Rheumatic Disease.
