OBJECTIVE To evaluate the therapeutic effectiveness of reducing the infliximab dose interval to 6 weeks in spondyloarthropathy patients not responding to 5 mg/kg every 8 weeks. METHODS After 30 weeks of infliximab therapy, 25 patients were classified as responders [Bath Ankylosing Spondylitis Activity Index (BASDAI) <4 cm or ESR <30 mm/h and CRP <5 mg/l, n = 15; group A] or non-responders (pa...

The use of musculoskeletal ultrasound (MSKUS) in rheumatology practice and research has increased steadily over the last decade. An ever-growing body of literature shows parity and even superiority of MSKUS when compared to physical examination, plain radiography, and more expensive and static imaging modalities such as MRI. While many use the modality for procedure guidance, investigators cont...

Psoriatic arthritis is a psoriasis-related spondyloarthropathy that occurs in 20-30% of patients with psoriasis. Various imaging studies have demonstrated that there is a considerable proportion of undiagnosed psoriatic arthritis among patients with psoriasis. Since early detection and treatment of psoriatic arthritis could, ultimately, allow the prevention of clinical and radiologic progressio...

Patients: 72 073 adults ≥ 40 years of age (mean age 65 y, 71% men) who had an incident diagnosis of gout. The control group comprised 358 342 adults without gout, matched for age, sex, date of study entry, and enrollment year. Exclusion criteria were history of septic arthritis, gout, osteoarthritis, rheumatoid arthritis, or other inflammatory rheumatic condition (seronegative spondyloarthropat...

Results Thirteen high to medium quality studies met the inclusion criteria. The majority of studies reported on US lesions in spondyloarthropathy (SpA), with limited evidence for other forms of IA. US lesions were not consistently defined with regard to Outcome Measures in Rheumatology Clinical Trials (OMERACT) definitions and numerous scoring systems were used across the majority of studies. T...

This study was to clarify whether Behcet's disease (BD) could be classified into the spondyloarthropathy (SpA) complex. It was undertaken on 58 patients with BD (BD group), 56 patients with SpA (SpA group), and 3 patients who concurrently satisfied the criteria for BD and SpA (BDSpA group). The clinical parameters and known susceptible HLA antigens were compared between BD group and SpA group. ...

Human class I major histocompatibility complex allele HLA-B27 is associated with a group of human diseases called "spondyloarthropathies." Studies on transgenic rats expressing HLA-B27 and human beta 2-microglobulin have confirmed the role of HLA-B27 in disease pathogenesis. Here we report spontaneous inflammatory arthritis in HLA-B27 transgenic mice lacking beta 2-microglobulin (B27+ beta 2m-/...

Melorheostosis is a rare benign bone pathology which can be responsible for incapacitating pain and bone deformations. Its imaging abnormalities are often typical. We describe here the case of a patient with melorheostosis involving the lower limbs, associated with a peripheral form of inflammatory spondyloarthropathy, who underwent 18FNa positron emission tomography coupled to a computed tomog...

Behcet's disease is a multisystem disease characterized by recurrent oral and genital ulcers, relapsing uveitis, mucocutaneous, articular, gastrointestinal, neurologic, and vascular manifestations. Rheumatologic manifestations may also occur in Behcet's disease, and arthritis and arthralgia are the most common musculoskeletal findings followed by enthesopathy, avascular necrosis, myalgia, and m...

Psoriatic arthritis (PsA) used to be considered a mild disease, but the development of erosive and deforming arthritis has been shown in a large proportion of patients. Disease modifying antirheumatic drugs (DMARDs) often do not achieve a satisfactory control of articular symptoms and there is no evidence of their effect on the progression of joint damage. Tumour necrosis factor α (TNFα) has a ...
