RESUMEN
OBJECTIVES: The aim of this study was to investigate cardiac involvement detected by ECG in patients with idiopathic inflammatory myopathies (IIMs) and to evaluate possible associations between the autoantibody profile and ECG changes in these patients. METHODS: In a Scandinavian cross-sectional study, patients were included from two Danish centres and one Swedish centre. Resting 12-lead ECG was investigated in 261 patients with IIM compared with 102 patients with systemic sclerosis (SSc) and 48 healthy controls (HCs). ECG changes were correlated to clinical manifestations and myositis-specific and myositis-associated autoantibodies (MSAs and MAAs, respectively). RESULTS: Patients with IIM had a longer mean corrected QT (QTc) duration and more frequently presented with prolonged QTc (≥450 ms; P = 0.038) compared with HCs. A longer QTc duration was recorded in SSc compared with IIM [433 ms (s.d. 23) vs 426 (24); P = 0.011], yet there was no significant difference in the fraction with prolonged QTc (SSc: 22%, IIM: 16%; P = 0.19). In multivariable regression analyses, anti-Mi2 (P = 0.01, P = 0.035) and anti-Pl-7 (P = 0.045, P = 0.014) were associated with QTc duration and prolonged QTc in IIM. Elevated CRP was associated with prolonged QTc (P = 0.041). CONCLUSION: The presence of QTc abnormalities was as common in patients with IIM as in patients with SSc, including prolonged QTc seen in almost one-fifth of the patients. Anti-Mi2, anti-Pl-7 and elevated CRP may serve as biomarkers for cardiac disease in IIM, but needs to be confirmed in a larger prospective study.

Legionella bozemanae is a rare isolate in clinical specimens. We describe a case of joint infection due to L. bozemanae in an immunocompromised patient with dermatomyositis. Without the use of PCR screening or culture on specialized medium, the organism would not have been detected.

A 27-year-old woman was admitted for intractable right-sided neck, ear, and jaw pain with gradual development of tinnitus and hearing loss. A cerebral MRI showed meningo-dural enhancement, and additional diagnostic workup revealed a right pulmonary infiltrate and positive PR-3 ANCA. Biopsies from nasal mucosa and lung showed chronic inflammation with granuloma formation. Based on these findings the patient was diagnosed with Wegener's granulomatosis with pachymeningitis. There was no clinical response to oral Prednisolone and Cyclophosphamide, but complete clinical and imaging remission was achieved by adding Rituximab.

INTRODUCTION: The aim of this study was to develop 3E (Evidence, Expertise, Exchange) recommendations (RCs) on the use of methotrexate in rheumatic disorders and to assess the agreement among Danish rheumatologists. MATERIAL AND METHODS: Based on a systematic literature review and Delphi votes, national and multinational (MN) RCs were developed by 751 rheumatologists from 17 countries including Denmark, and the degree of agreement among the participants was assessed. Subsequently, a survey regarding the agreement on the MN RCs was sent to all Danish rheumatologists. RESULTS: A total of 24 Danish RCs were elaborated by 43 rheumatologists at a national meeting. 71-100% (median 94%) of the participants agreed with each of the RCs. A total of 73 rheumatologists answered the survey on the ten MN RCs. On numerical rating scales with values ranging from zero to ten, the median agreement score for each of these RCs ranged from eight to ten. The RCs were already applied in daily practice by 70-100% (median 91%) of the specialists. Any direct conflict between the national and MN RCs was not evident. CONCLUSION: Based on evidence and expert opinion in a MN approach, national and MN RCs on methotrexate therapy were developed and a high level of agreement among Danish rheumatologists was evidenced.
