The aim of this study was to examine the influence of different MRI unit field strengths, coil types and image resolutions on the OMERACT RA MRI scoring system (RAMRIS) of bone marrow oedema (BME) and image quality. ⋯ No major, consistent differences were found between BME scores using STIR sequences obtained at different field strengths, coil types and image resolutions, suggesting that these are equally suited for assessment of BME in RA. However, parameters of image quality and intrareader reliability (favouring 0.6, 1.5 and 3T) should be considered when selecting the MRI acquisition strategy.

Interstitial lung disease (ILD) is a frequent extra-articular manifestation of RA associated with increased mortality. High-resolution CT (HRCT) is used for diagnosis and follow-up, but its accuracy is counterbalanced by high costs and radiological risk. In the presence of ILD, lung US (LUS) detects vertical artefacts called B-lines. The aims of the present study were to evaluate the accuracy of LUS in the diagnosis of ILD in RA and to validate the use of a pocket-size US device (PS-USD) as a screening tool. ⋯ The sensitivity of LUS in the detection of ILD supports its use as a screening test for ILD in RA patients, even in the ambulatory setting with a PS-USD. The strong correlation between echographic and HRCT scores indicates LUS is a valid tool for grading and follow-up of ILD.

There is no consensus on whether restarting TNF inhibitors (TNFis) after treatment of an active tuberculosis (TB) infection caused by previous TNFi exposure is safe. In this study we sought to determine the safety of resuming TNFis in patients following TB treatment. ⋯ Our results suggest that resuming TNFi therapy in patients following adequate TB treatment is safe, even before completion of TB treatment.
