Psoriatic Arthritis: From Leeds to the Limelight

Christopher Ritchlin, MD, MPH, and Philip Helliwell, MD, PhD  |  Issue: August 2009  |  

Dr. Wright would have appreciated the great upsurge in interest in PsA, and he would have been an active member of GRAPPA. If he were alive today, Dr. Wright would surely champion additional collection of information, and he would embrace clinical and scientific advances even if they challenged his earlier findings. Indeed, it is likely that the diverse subsets first proposed by Dr. Wright reflect heterogeneous disease pathways that we are still attempting to understand, and perhaps different therapeutic strategies will be required depending on the clinical phenotype. Armed with sophisticated tools for laboratory investigation, genetic analysis and imaging investigators will no doubt unveil new disease mechanisms and formulate new paradigms to explain the remarkable clinical phenotypes of PsA first described by Dr. Wright more than 50 years ago.

Dr. Ritchlin is a professor of medicine at the University of Rochester Medical Center in Rochester, N.Y. Dr. Helliwell is senior lecturer in rheumatology at the University of Leeds, United Kingdom.
