Research Summary

Dr. Louie has a strong research interest in the field of spondyloarthritis. He has established a growing cohort of patients with spondyloarthritis; some have longstanding ankylosing spondylitis, while others have early disease with nonradiographic axial spondyloarthritis.

With his ongoing and active experience in outcomes and epidemiologic research, Dr. Louie will be using the cohort to capture longitudinal data (patient self-report, clinical and imaging) and to store biological specimens from patients with spondyloarthritis. The data will be analyzed to more precisely phenotype patients with spondyloarthritis, reflective of the diversity of the disease expression. Stored biological specimens permit biochemical, genetic and other laboratory studies to be conducted that may facilitate the understanding of the etiopathogenesis of disease and the identification of novel therapeutic targets.
