  Purpose

Inflammatory arthritis particularly rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis are potentially disabling conditions which cause joint pain, swelling and deformity and treatments are aimed at preventing these complications. Although treatment has improved with the advent of antiTNFalpha therapies, up to 30% of patients fail to respond to this treatment and in others, treatment is associated with significant side effects. The precise mechanisms of this remain unclear. In addition, there are no sensitive methods available to monitor or predict disease response to treatment aside from testing inflammatory markers in the blood. Understanding the mechanism of action and what governs response to antiTNF therapy will allow development of more specific therapies for inflammatory arthritis. Work in animal models of rheumatoid arthritis has characterised a novel cell type, Th17 cells, important in the inflammatory cascade which are affected in a particular way by antiTNF therapies and may underpin their mechanism of action and side effects. We aim to translate these findings into patients with rheumatoid arthritis and other conditions treated with anti-TNF therapy, such as psoriatic arthritis and ankylosing spondylitis. Patients from rheumatology clinics within NHS trusts will be recruited. We will correlate disease activity assessed by clinical parameters, ultrasonography and questionnaires with biomarkers in the blood and target tissues, such as synovium and skin.

Patients with rheumatoid arthritis

  • Only patients meeting the 1987 American College of Rheumatology (ACR) revised classification criteria for rheumatoid arthritis will be included
  • Patients should have active rheumatoid arthritis, defined by an initial DAS28 score >5.1
  • Patients should have at least 1 joint suitable for synovial biopsy
  • Patients can be on concurrent DMARDs but they should have been on a stable dose of DMARD for at least 1 month prior to study entry
  • Patients can be on a concurrent dose of glucocorticoids (up to 10mg daily) and they should have been on a stable dose for at least 4 weeks prior to study entry

Patients with psoriatic arthritis

  • Patients should have a secure diagnosis of psoriatic arthritis determined by a rheumatologist
  • Patients with psoriatic arthritis included in this study should have evidence of concurrent psoriatic skin lesions at the time of study entry
  • Patients should have at least one joint suitable for synovial biopsy
  • Patients can be on concurrent DMARDs - they should be on a stable dose of DMARD for at least 1 month prior to study entry

Patients with Ankylosing spondylitis

  • Patient should fulfil the Modified New York Criteria for diagnosis of ankylosing spondylitis
  • Patients can be on concurrent NSAIDs

  • Patients with rheumatoid arthritis, psoriatic arthritis or ankylosing spondylitis who do not fulfil the diagnostic criteria for these conditions as above
  • Patient who have received an intra-articular injection of steroids or have received an intra-muscular injection of depot steroid to treat disease flare in the preceding 4 weeks prior to commencing anti-TNF therapy.
  • Patients with intercurrent, active infection of any type, excluding the common cold
