L IJsselstijn, A A van Houten, F Weerkamp
Interpretation of laboratory parameters in cases of haemochromatosis can be difficult. Here, we describe two patients with markedly elevated transferrin saturation and high ferritin levels. The first patient is a 51-year-old woman who had been complaining of fatigue, abdominal pain and arthritis for three years. Her liver enzymes were mildly elevated. Secondary causes of iron overload had been excluded. DNA investigation found a homozygous p.Cys282Tyr mutation in the HFE protein, consistent with hereditary haemochromatosis...

BACKGROUND: Ultrasonography (US) studies carried out on joints of juvenile idiopathic arthritis (JIA) patients in clinical remission demonstrate the presence of subclinical synovitis. The significance of subclinical synovitis and the positive power Doppler (PD) signal on US in JIA in clinical remission is not well understood. The objectives of this study were to assess whether the changes detected by US in patients with JIA in clinical remission can predict disease flare and to evaluate factors associated with flare and joint damage over 30 months of follow-up...

Rheumatoid arthritis (RA) is a common, chronic systemic inflammatory disease of unclear aetiology leading to synovial hypertrophy and joint inflammation. It typically presents with symmetrical polyarthritis of small joints of the hands or feet, but can also involve larger joints, and have associated extra-articular manifestations. Diagnosis is based on duration of symptoms, joint distribution, level of inflammatory markers and autoantibodies i.e. rheumatoid factor(RhF) and anty-cyclic citrullinated peptide (CCP) antibodies...

Ultrasound imaging may have an impact in management patients with rheumatoid arthritis. Through technological improvements, ultrasonography, has become an established imaging technique for the diagnosis and the follow up of this inflammatory chronic disease. In fact, ultrasounds, allow follow up during treatment by evaluating synovitis count and assessment of synovial vascularization by Power Doppler. Besides, erosions are found sooner and more frequently by ultrasonography than with conventional radiography...

PURPOSE AND HYPOTHESIS: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory. The hypothesis that contrast-enhanced ultrasound (CEUS) could detect with more sensibility than PD the new vessel ingrowth in human degenerated Achilles tendons and therefore the correlation of neovascularization with pain and disability, was evaluated...

OBJECTIVE: Reactive arthritis (ReA) is an inflammatory disorder occurring several weeks after gastrointestinal or genitourinary infections. HLA-B27 positivity is considered a risk factor, though not necessarily predictive of disease incidence. Among non-genetic factors, the intestinal microbiome may play a role in disease susceptibility. The objective of this study was to characterize the gut microbiota and host gene interactions in ReA and post-infectious spondyloarthritis. METHODS: Adult peripheral spondyloarthritis and control subjects with preceding infections that did not develop arthritis were prospectively recruited from a highly prevalent geographic region...
