Rheumatoid arthritis (RA) is the most prominent member of a vast number of immune mediated inflammatory diseases. It affects approximately 1-2% of the population, with no cure and >1 million patients having severe disability and reduced life expectancy.
A stepwise progression alongside the inflammatory arthritis continuum (IACon) of disease is clearly detectable clinically and is now a recognised concept, with a pre-clinical phase characterised by systemic autoimmunity (presence of anti-citrullinated peptide antibodies autoantibodies ACPA) but with no evidence of joint involvement; a phase of non-specific joint pain known as arthralgia, followed by the development of joint inflammation, which may or may not develop to RA. At this last stage, treatment is initiated.
This project will use previous flow cytometry data from panels that were developed to predict the progression alongside the IACon towards developing a novel kit that can be used by hospitals worldwide. Indeed, over the past 20 years, our group has demonstrated the potential of phenotyping CD4+T-cell as biomarkers for predicting patient’s progression alongside the IACon (references below). We have now reached the stage of these biomarkers being used to stratify patients in randomised clinical trials.
The project will progress around several objectives towards developing a routine test for rationalising the management of RA patients using stratification based on T-cell phenotyping biomarkers
- Objective 1: The Technical development of
- a novel flow cytometry kit (based on wet or dry tube technology), in collaboration with BD UK
- working with an industrial partner, establishing the basis for a centralised service for T-cell phenotyping using frozen blood samples for future international clinical trials
- Objective 2 : the Clinical validation/replication of findings alongside the IACon
- using the novel KIT comparing its performance to the current flow cytometry panel
- working with clinician to validate further the clinical utility of the stratification strategies using T-cell phenotyping (internationally, via collaboration)
- Objective 3 : Develop SOPs for the use of the new Kit by hospital flow cytometry services as well as instruction for the analysis gating strategy with BD.
All are important outcomes, both for millions of patients and their families but also to sustain a more rational and socioeconomic management of RA and for the future of rheumatology.
Flow cytometry mainly, modelling of clinical outcome.
