OBJECTIVE To assess the presence of Chlamydia pneumoniae DNA in the joints of patients with reactive arthritis (ReA) and other arthritides. METHODS DNA was prepared from synovial tissue (ST) and several synovial fluid (SF) samples from 188 patients with either ReA, undifferentiated oligoarthritis, or other forms of arthritis, and from 24 normal(More)
OBJECTIVE Rheumatoid arthritis (RA) is considered a Th1-driven disease. Interleukin 4 (IL-4) binds to its receptor, promoting Th2 differentiation and limiting Th1 responses, but its role in the pathogenesis of RA is conflicting. We analyzed 2 polymorphisms of the IL4 gene and 4 polymorphisms of the IL4RA gene in patients with RA and in a control population,(More)
OBJECTIVE Analyses were conducted to examine the baseline burden of illness and compare the effect of etanercept (ETN) versus placebo (PBO) on quality of life (QOL) in patients with nonradiographic axial spondyloarthritis (nr-axSpA) who failed nonsteroidal antiinflammatory drugs (NSAID). METHODS Patients fulfilling the Assessment of Spondyloarthritis(More)
INTRODUCTION Rheumatoid arthritis is an inflammatory disease driven by TH1 CD4+ cells. Interleukin-10 is present in higher concentrations in serum and synovial fluid from patients with rheumatoid arthritis and has a marked anti-inflammatory activity. Furthermore, it is capable of stimulating B cells and increasing autoantibody production. Interleukin-10(More)
Percutaneous needle biopsies of synovium are successfully used for diagnosis and investigation of joint disease by an increasing number of groups around the world. This procedure can be done in the office with little morbidity; a large number of samples can minimize the potential limitation of sampling error. Clinical indications for 'imaging the joint' by(More)
Subcutaneous tophaceous deposits of monosodium urate, in the absence of arthritis, may occasionally occur as the initial manifestation of gout. In this report, we describe a 35-year-old man who presented with a 6-year history of multiple subcutaneous nodules and no history of previous articular complaints. Needle aspirations of the nodules proved them to be(More)
OBJECTIVE To assess the intra- and inter-observer reliability of ultrasound (US) in scoring B-mode, Doppler synovitis and combined B-mode and Doppler synovitis scores in different peripheral joints of rheumatoid arthritis (RA) patients. METHODS Four rheumatologists with a formal training in musculoskeletal US (MSKUS) particularly focus on definitions and(More)
The objective of this study is to evaluate inter-reader entheses ultrasound (US) reliability and the influence of the type of image or degree of sonographer experience on US reliability in patients with spondyloarthritis (SpA). Eighteen Latin American ultrasonographers with different experience took part in an US reading exercise evaluating 60 entheseal(More)
Septic arthritis is an unusual complication of Sporothrix schenckii infection. Its diagnosis can be very difficult, mainly because of low clinical suspicion, special media needed for its culture, and low density of the organism in biopsy specimens. We present a case of a woman with disseminated Sporothrix schenckii infection and polyarthritis. Although(More)
