  • Paying attention to carpal tunnel contents lesions: ultrasound for evaluation of carpal tunnel syndrome
    Jiaan Zhu

    Dear Editor,

    We read with great interest the report by Dejaco and co-authors related to diagnosis of carpal tunnel syndrome (CTS) by ultrasound [1]. Dejaco et al. compared ultrasound measurement of median nerve cross- sectional area (CSA) at different anatomical landmarks in great detail and evaluated the value of intranerval power Doppler signals for CTS diagnosis. It provided a good data support for the ultrasonic...

  • Response to:Comorbidities in a Mexican Mestizo cohort with established rheumatoid arthritis
    Maxime Dougados

    Dear Editor,

    On behalf of the investigators of the COMORA study, we would like to congratulate for the study you have conducted in Mexican mestizo patients. The results observed are totally in accordance with the results observed in the COMORA study that is: 1/ a relevant percentage of rheumatoid arthritis patients with comorbidities and 2/ a huge inter-country variability.

  • The concept of axial spondyloarthritis. Lessons from the INFAST study
    Henning Zeidler

    Dear Editor,

    Sieper et al. evaluated whether combination therapy with Infliximab (IFX) and naproxen (NPX) was superior to treatment with NPX alone in patients who had active moderate-to-severe early (disease duration under 3 years) active axial spondyloarthritis (SpA) and who were naive to nonsteroidal anti-inflammatory drugs (NSAIDs) or had only been treated with a submaximal dose of NSAIDs (1). This study is the...

  • Comorbidities in a Mexican Mestizo cohort with established rheumatoid arthritis
    David Vega-Morales

    Dear editor,

    In the study recently published in the Annals of Rheumatic Diseases, Dougados et al. [1] evaluated the prevalence of comorbidities and compared their management in Rheumatoid Arthritis (RA) patients from different countries. We know that RA is a chronic autoimmune disease characterized by chronic inflammation, progressive deterioration of joint function, increased comorbidity and mortality; RA pati...

  • Response to: Detection of anti-nuclear antibodies. Added-value of solid phase assay?
    Nancy Agmon-Levin

    Dear Editor,

    We have read the letter by Bossuyt X. and Fieuws S. entitled "Detection of anti-nuclear antibodies, added-value of solid phase assay?" with great interest (1). In this letter the authors described a comparison between anti-nuclear antibodies (ANA) performed by indirect immunofluorescent assay(IIFA) and by an automated method (fluoroenzymeimmunoassay; EliA CTD screen, Thermo Fisher) using samples obtai...

  • Response to: Five Factors Score in patients with eosinophilic granulomatosis with polyangiitis (Churg-Strauss; EGPA): to use or not to use?
    Loic Guillevin

    Dear Editor,

    Moiseev and Novikov's comments on the Five-Factor Score (FFS) for eosinophilic granulomatosis with polyangiitis (EGPA) provide the opportunity to address the contribution of scores and their use. The FFS was designed to evaluate necrotizing vasculitis prognosis and identify manifestations associated with death: those are its only roles. Its strength is its validation on 1,108 patients with differen...

  • Response: Is (creno)balneotherapy a drug, a surgical procedure or a non-pharmacological treatment?
    Thea P Vliet Vlieland

    Dear editor,

    We thank Forestier and Erol for their response on our paper on Eular recommendations for the non-pharmacological core management of hip and knee osteoarthritis (OA). We agree that balneotherapy is a relevant non- pharmacological intervention in hip and knee OA, and has been properly evaluated by means of randomised clinical trials, with the evidence summarized in systematic reviews. The topics to be in...

  • Five Factors Score in patients with eosinophilic granulomatosis with polyangiitis (Churg-Strauss; EGPA): to use or not to use?
    Sergey V Mooiseev

    Dear Editor,

    In the excellent study recently published in the Annals of the Rheumatic Diseases [1] F.Moosig et al. evaluated the individualized and more aggressive strategy of immunosuppressive treatment in 150 patients with EGPA. Over the last decade we utilized the same approach in our cohort of 117 patients with EGPA. For induction of remission the authors used cyclophosphamide in patients not only with Five Fac...

  • Is (creno)balneotherapy a drug, a surgical procedure or a non-pharmacological treatment?
    Romain J FORESTIER

    Dear Editor,

    We appreciate that EULAR is preparing a specific recommendation on non-pharmacological treatment of knee osteoarthritis but we are also very surprised to discover that crenobalneotherapy was not even mentionned in the analysed treatments. Crenobalneotherapy (also called balneotherapy or spa therapy) is a very common treatment for knee osteoarthritis in South and Eastern Europe, Middle Asia, Japan, Sou...

  • Visualization of structural damage as a surrogate marker of radiographic progression in patients with rheumatoid arthritis
    Alexander Pfeil

    Dear Editor,

    The article published by Landewe et al. (1) offers novel insights to assess the benefits of new therapeutic strategies in rheumatoid arthritis (RA) which focus more on [the visualization of] structural integrity rather than the inhibition of radiographic progression (1). The authors clearly outline the three major problems of the common superiority study designs:
    I. Differences in progression are...
