NKG2D ligands in inflammatory joint diseases: analysis in human samples and mouse models.

Objectives: NKG2D ligands (NKG2DLs) are stress-inducible molecules involved in multiple inflammatory settings. In this work, we quantified MICA, an NKG2DL, in the synovial fluid of patients suffering various arthritides and measured Nkg2dLs gene expression in murine models of acute joint inflammation.

Methods: Soluble MICA (sMICA) was quantified by ELISA is synovial fluids harvested from patients suffering osteoarthritis, rheumatoid arthritis, psoriatic arthritis, calcium pyrophosphate crystal arthritis, urate crystal arthritis and reactive arthritis.

Mitochondria: An Organelle of Bacterial Origin Controlling Inflammation.

Inflammation is a cellular and molecular response to infection and/or tissues injury. While a suited inflammatory response in intensity and time allows for killing pathogens, clearing necrotic tissue, and healing injury; an excessive inflammatory response drives various diseases in which inflammation and tissues damages/stress self-sustain each other. Microbes have been poorly implied in non-resolving inflammation, emphasizing the importance of endogenous regulation of inflammation.

Grade and location of power Doppler are predictive of damage progression in rheumatoid arthritis patients in clinical remission by anti-tumour necrosis factor α.

Objectives: To investigate power Doppler (PD) signal, grade and location and their association with radiographic progression in RA patients in remission.

Methods: A prospective observational study was conducted in 125 consecutive RA patients in stable 28-joint DAS (DAS28) remission (⩾6 months) achieved on anti-TNF-α. At baseline, patients in stable remission underwent radiographic and US examination of the wrists and MCP, PIP and MTP joints.

Self-reported flares are predictors of radiographic progression in rheumatoid arthritis patients in 28-joint disease activity score remission: a 24-month observational study.

Background: Disease flares are common in rheumatoid arthritis (RA) and are related to structural damage. However, few data on the impact of flares reported by patients on radiographic progression are available. Our aim was to investigate whether overall flares (OF), self-reported flares (SRF) and short flares assessed at the visit (SF) predict radiographic progression in RA patients in DAS28 (28-joint disease activity score) remission.

Effects of half dose etanercept (25 mg once a week) on clinical remission and radiographic progression in patients with rheumatoid arthritis in clinical remission achieved with standard dose.

Objectives: This prospective long-term follow-up study evaluated the effects of half-dose etanercept (25 mg weekly) on clinical remission and radiographic progression in a large cohort of patients with rheumatoid arthritis (RA) in clinical remission after etanercept 25 mg bi-weekly.

Methods: 524 biologic-naïve RA patients were treated with etanercept 25 mg bi-weekly after failure of conventional drugs. Patients achieving remission (DAS28 <2.

Inefficacy or paradoxical effect? Uveitis in ankylosing spondylitis treated with etanercept.

Ankylosing spondylitis (AS) is presented with axial and peripheral articular involvement. Uveitis is a severe and rather specific manifestation of AS. Biologics targeting tumor necrosis factor (TNF) α are effective on both articular and ocular manifestations of disease.

MR and CEUS monitoring of patients with severe rheumatoid arthritis treated with biological agents: a preliminary study.

Purpose: This study was done to propose a study protocol for patients with rheumatoid arthritis (RA) treated with biological agents, by evaluating the contribution of contrast-enhanced magnetic resonance (CE-MR) imaging, a software programme that calculates the volume of synovitis on CE-MR images, and contrast-enhanced ultrasound (CEUS).

Materials And Methods: Sixteen patients with RA receiving treatment with biologics were analysed. The patients underwent clinical examination, CE-MR imaging and CEUS on the same day.

Methods used to assess remission and low disease activity in rheumatoid arthritis.

The aim of the treatment in rheumatoid arthritis (RA) is to prevent articular damage and functional loss by decreasing the activity of the disease. The overall goal is the full suppression of the activity of the disease, also called clinical remission. The most reliable indices to assess RA activity were defined by the American College of Rheumatology (ACR), the European League Against Rheumatism (EULAR) and the International League Against Rheumatism (ILAR) and are habitually used for the evaluation of remission.
