Ankylosing spondylitis is a common form of inflammatory arthritis predominantly affecting the spine and pelvis that occurs in approximately 5 out of 1,000 adults of European descent. Here we report the identification of three variants in the RUNX3, LTBR-TNFRSF1A and IL12B regions convincingly associated with ankylosing spondylitis (P < 5 × 10(-8) in the(More)
OBJECTIVE To assess the efficacy of a single intra-articular injection of triamcinolone hexacetonide (THA) in knee osteoarthritis (OA) and examine factors which may relate to treatment efficacy. METHODS Eighty four patients with clinical and radiographic evidence of knee OA were recruited and randomly allocated to receive either THA (20 mg in 1 ml) or(More)
OBJECTIVE The transcription factor nuclear factor kappaB (NF-kappaB) has been implicated in the inflammatory response and is known to be activated by a process involving reactive oxygen intermediates. The purpose of the present study was to demonstrate the presence and distribution of activated NF-kappaB in synovium samples from patients with rheumatoid(More)
OBJECTIVE To ascertain the extent of methotrexate (MTX)-related pancytopenia at the Norfolk and Norwich University Hospital (NNUH) between 1999 and 2004. METHODS Patients were identified by a department database search, review of pharmacy records and personal communication. Pancytopenia was defined as white blood cell count (WBC) <3.5 x 10(9)/l,(More)
OBJECTIVE To determine the one-year period prevalence and factors associated with falls in a community based cohort of women with established inflammatory polyarthritis (IP). METHODS The Norfolk Arthritis Register is a primary-care based inception cohort of subjects with IP aged 16 years and over. At the 10-year visit, subjects completed the Health(More)
OBJECTIVE To examine the relation between rate of synovial membrane enhancement, intra-articular pressure (IAP), and histologically determined synovial vascularity in rheumatoid arthritis, using gadolinium-DTPA enhanced magnetic resonance imaging (MRI). METHODS Dynamic gadolinium-DTPA enhanced MRI was performed in 31 patients with knee synovitis (10(More)
Ankylosing spondylitis (AS) is a common, highly heritable, inflammatory arthritis for which HLA-B*27 is the major genetic risk factor, although its role in the aetiology of AS remains elusive. To better understand the genetic basis of the MHC susceptibility loci, we genotyped 7,264 MHC SNPs in 22,647 AS cases and controls of European descent. We impute(More)
OBJECTIVE To investigate whether antidrug antibodies and/or drug non-trough levels predict the long-term treatment response in a large cohort of patients with rheumatoid arthritis (RA) treated with adalimumab or etanercept and to identify factors influencing antidrug antibody and drug levels to optimize future treatment decisions. METHODS A total of 331(More)
