Dr. Pamela Weiss is an experienced academic pediatric rheumatologist with advanced training in clinical epidemiology and a focus on early diagnosis, accurate phenotyping, and targeted treatment of children with juvenile arthritis. Her research consists of a mixture of prospective interventional, prospective observational and retrospective large database-driven work.

Dr. Weiss's research focuses on juvenile SpAand juvenile arthirtis.

Juvenile SpA is heterogeneous group of disorders characterized by arthritis, enthesitis (inflammation of the tendon insertions) and axial arthritis (spine and sacroiliac joints) accompanied by overlapping genetic susceptibility. Dr. Weiss has directed efforts to optimize evaluation of early disease phenotype. Prior projects addressed prevalence of sacroiliitis in incident cases of SpA and optimization of the imaging evaluation for detection of axial arthritis.

Dr. Weiss has also developed and validated a composite disease activity outcome that can be used in both routine care and clinical trials. Additionally, MRI is currently the most utilized modality to diagnose sacroiliitis in children, but there is an unmet need for objective measures of inflammation and damage that can be utilized to assess change over time. Dr. Weiss has worked with international colleagues to evaluate scoring systems for inflammation and structural damage at the sacroiliac joint to assess their reliability in the pediatric population.

Dr. Weiss also investigates patient-reported outcomes in juvenile SpA and juvenile arthritis. She has evaluated disparities in PRO across juvenile arthritis categories and is working to incorporate PRO evaluation into routine clinical assessments and outcomes for clinical trials.

Since there is no standardized approach to the initial treatment of juvenile arthritis, understanding the comparative effectiveness of the diverse therapeutic options and standardization of care will result in better health outcomes. Dr. Weiss co-chaired the American College of Rheumatology's 2013 update of the juvenile arthritis treatment recommendations. She also worked with the Childhood Arthritis and Rheumatology Research Alliance to develop consensus treatment plans for systemic and polyarticular arthritis. She is currently a co-investigator on a PCORI grant to study the comparative effectiveness of the polyarticular juvenile arthritis consensus treatment plans.
