Background RA flares are common and disabling. They are described in terms of worsening pain, swelling, or other symptoms. We aimed to determine characteristics, antecedants and sequelae of painful and inflammatory flare subtypes during the first 11... Read More

Discrete trajectories of resolving and persistent pain in people with rheumatoid arthritis despite undergoing treatment for inflammation: results from three UK cohorts (2019)
Journal Article
McWilliams, D. F., Dawson, O., Young, A., Kiely, P., Ferguson, E., & Walsh, D. A. (2019). Discrete trajectories of resolving and persistent pain in people with rheumatoid arthritis despite undergoing treatment for inflammation: results from three UK cohorts. Journal of Pain, doi:10.1016/j.jpain.2019.01.001

Rheumatoid arthritis (RA) is an example of human chronic inflammatory pain. Modern treatments suppress inflammation, yet pain remains a major problem for many people with RA. We hypothesised that discrete RA subgroups might display favourable or unfa... Read More

Introduction: The mounting evidence that osteoclasts play an important role in osteoarthritis (OA) pain lead us to investigate the effects of L-006235, a potent and selective inhibitor of cathepsin K, on pain behaviour and joint pathology in a model... Read More

Prediction of persistent knee pain by pressure pain detection thresholds: results from the Knee Pain In the Community cohort (KPIC) (2018)
Conference Proceeding
McWilliams, D. F., Frowd, N., Marshall, L., Stocks, J., Sarmanova, A., Fernandes, G. S., …Walsh, D. A. (2018). Prediction of persistent knee pain by pressure pain detection thresholds: results from the Knee Pain In the Community cohort (KPIC)

Background: Knee pain results from a combination of nociceptive input from the joint, and processing by the central nervous system. Pressure pain detection thresholds (PPTs) are lower and pain is more severe in people with greater central sensitisat... Read More

Interpretation of DAS28 and its components in the assessment of inflammatory and non-inflammatory aspects of rheumatoid arthritis (2018)
Journal Article

Background: DAS28 is interpreted as the inflammatory disease activity of RA. Non-inflammatory pain mechanisms can confound assessment. We aimed to examine the use of DAS28 components or DAS28-derived measures that have been published as indices of no... Read More

Journal Article
Cottam, W. J., Iwabuchi, S. J., Drabek, M. M., Reckziegel, D., & Auer, D. P. (2018). Altered connectivity of the right anterior insula drives the pain connectome changes in chronic knee osteoarthritis. PAIN, 159(5), doi:10.1097/j.pain.0000000000001209

Resting-state functional connectivity (FC) has proven a powerful approach to understand the neural underpinnings of chronic pain, reporting altered connectivity in three main networks: the default mode (DMN), central executive (CEN), and the salience... Read More

This study aimed to identify self-report correlates of central pain augmentation in individuals with knee pain. A subset of participants (n=420) in the Knee Pain and related health In the Community (KPIC) baseline survey undertook pressure pain thres... Read More

Discordance between pain and inflammation in rheumatoid arthritis (2018)
Conference Proceeding
McWilliams, D. F. (in press). Discordance between pain and inflammation in rheumatoid arthritis

Recent research interest has focused on the continuing problem of pain in RA. The long term prognosis for pain could be improved, even when inflammation is being suppressed. This talk will describe the progression of pain, and examine how factors oth... Read More

Pain mechanisms in rheumatoid arthritis (2017)
Journal Article
McWilliams, D. F., & Walsh, D. A. (2017). Pain mechanisms in rheumatoid arthritis

Understanding of the causes and underlying mechanisms of pain in people with RA is rapidly changing. With the advent of more effective disease modifying drugs, joint inflammation is becoming a more treatable cause of pain, and joint damage can often... Read More
