    Research Summary

    Dr. Baer is engaged in a number of research studies in the area of both Sjogren’s syndrome and gout. He was the principal investigator of the NIH subcontract to Johns Hopkins to conduct the Sjogren’s International Registry (SICCA) and enrolled 300 patients into the registry. The SICCA registry was utilized to develop the 2012 ACR classification criteria for Sjogren’s syndrome. It has also been a rich source of clinical data and biospecimens for research that Dr. Baer is conducting with colleagues at both Hopkins and the University of California-San Francisco. He is conducting a longitudinal observational study of patients with Sjogren’s syndrome and is directing a clinical trial of baminercept in Sjogren’s syndrome at Hopkins organized by the Autoimmunity Centers of Excellence. He is collaborating with Dr. Mara McAdams DeMarco (Bloomberg School of Public Health) on epidemiologic studies of gout, using the Atherosclerosis Risk in Communities cohort, and with Dr. John Carrino (Department of Radiology) on the utility of dual energy computed tomography in gout.
