Biologic disease-modifying agents (bDMARDs) are highly effective in controlling the symptoms of autoimmune rheumatic diseases. The decision on whether to continue bDMARDs following a cancer diagnosis can be challenging for patients and physicians. Here, we describe a case of a middle-aged male with ankylosing spondylitis who was controlled on infliximab (IFX) and found to have a myeloid neoplasm with Platelet-Derived Growth Factor Receptor Beta rearrangement. The patient was started on a tyrosine kinase inhibitor imatinib. Given its significant positive effect on patient's quality of life, IFX was continued with a favorable outcome. This case highlights the importance of shared decisionmaking in balancing risks and benefits of immunosuppressants in appropriate cases of hematologic malignancy.

Musculoskeletal ultrasound has become a practical and accessible diagnostic tool for musculoskeletal diseases. It is used to examine joints, tendons, vessels, and nerves due to its wide availability in rheumatology practice. Ultrasound has also been applied for years in other areas such as muscular injuries in sports activities and rheumatic diseases with inflammation such as myositis. The knowledge among rheumatologists about muscle ultrasound is increasingly growing taking into account it is not the main target of their ultrasound activity but mainly based on the evaluation of joint, synovitis, tenosynovitis, vasculitis in giant cell arteritis, and parotid gland evaluation in Sjögren´s syndrome. Thus, the present review describes anatomical and ultrasound findings including all muscles of the thigh (anterior, posterior, medial aspects) and leg (anterior, lateral, posterior superficial, deep posterior compartments) of lower limb structures to ease a comprehensive clinical and sonographic evaluation.

The interpretation of lung ultrasound (US) is the result of the analysis of artifacts, rather than exact representations of anatomical structures, which appear when changes in the physical properties of the lung occur. Its application to the study of interstitial lung disease (ILD) associated with autoimmune diseases has aroused great interest in the last 10 years, as evidenced by a growing number of publications studying its usefulness in the diagnostic process, as a prognostic marker, and as an aid in monitoring of patients. The main elements in lung US interpretation in ILD are the B lines and the changes in the pleural line. B lines are vertical artifacts that are generated when there is a partial decrease in the air content of the lung parenchyma and/or the volume of the interstitial area expands. Pleural line alterations that can be seen are irregularities, thickening, fragmentation, or subpleural nodules. Both the B lines and the changes in the pleural line have shown a significant positive correlation with the evidence on chest computed tomography (high-resolution computed tomography [HRCT]) of ILD associated with autoimmune diseases, with sensitivity and negative predictive values of up to 100%. These results, together with the safety, accessibility, and low cost of lung US, support this imaging technique as a promising screening method for optimizing the indication for HRCT. The role of lung US regarding sensitivity to change needs further investigation with multicenter prospective studies.

Objective: We provided an overview of narrative reviews, systematic reviews, and meta-analyses that summarize primary evidence of how physical activity (PA) relates to structural progression of knee osteoarthritis (OA). This overview can serve as a resource for healthcare providers when recommending PA to patients with, or at risk, for knee OA.

Methods: We searched the PubMED database for publications on "exercise" [MeSH Terms] and "knee osteoarthritis" [MeSH Terms]. We restricted our search to review articles, originally published in English, from 2005 to 2020. We then added several original studies to provide more detailed support of the findings of the review articles, based on the authors familiarity with the literature.

Results: We summarized the findings of 20 reviews and an additional 12 original studies. We found consistent evidence that common forms of PA (walking, running, and certain recreational sports) are not related to structural progression of knee OA, and can be safely recommended to patients with, or at risk, for knee OA.

Conclusion: Healthcare providers can refer to this overview of the evidence, as well as current PA guidelines, when recommending PA to their patients with, or at risk for, knee OA. Future studies can support PA guidelines that target preserving the structural integrity of the knees.

Objective: Recommendations for the treatment of cytokine release syndrome/macrophage activation syndrome (MAS) associated with coronavirus disease-2019 (COVID-19) are still of poor quality. IL-6 is an important therapeutic target as a main mediator of cytokine storm. The aim of our study was to evaluate the tocilizumab (TCZ) efficacy and factors affecting the therapy outcome.

Methods: This retrospective study included 27 patients treated with TCZ for COVID-19-MAS. All patients in this study were treated with TCZ (intravenously, at a dose of 8 mg kg1 ) in addition to standard therapy. Clinical improvement (survival and decreased oxygen demand) on the 10-14th days and secondary infection rate were assessed.

Results: In our 27 treated patients, 14 (51.8%) received TCZ in the intensive care unit (ICU) and seven (25.9%) were need to invasive mechanical ventilation (IMV). Fifteen (55.6%) of these patients revealed a good clinical response (four patients discharge from the ICU and 11 patients who followed-up in nonICU beds showed a decrease in oxygen demand). TCZ was significantly less effective in patients having high Murray lung injury score, low PO2/FiO2 ratio, IMV, and ICU admission (P < .05). Severity of hypoxemia was found as a single independent risk factor in the multivariable analysis (P < .05). Secondary bacterial infections rate was significantly higher in intubated patients (P < .01) or treated in the ICU (P ¼ .01).

Conclusion: TCZ was showed limited efficacy for COVID-19-related MAS. The most important predictive indicator for therapy outcome was found as the severity of hypoxemia. In addition, IMV and/or ICU was associated with the poor outcome and high side effect. So, controlled trials are still needed to confirm the indications and timing of TCZ therapy.

Objective: The aim of this qualitative research was to identify physician-perceived patient and clinic barriers to patient recruitment in a rheumatoid arthritis (RA) pragmatic trial of anti-tumor necrosis factor (TNF) biologic versus non-TNF biologic/Janus-Kinase inhibitor initiation after an inadequate response to methotrexate.

Methods: Semistructured telephone interviews were conducted with 26 rheumatologists in March 2019. An exploratory thematic analysis approach was used to analyze the interview data.

Results: Physician perceived patient barriers to the implementation of an RA pragmatic trial. This theme covers three subthemes: (1) patients' personal barriers, (2) patients' treatment-related factors, and (3) trial-related factors (eg, patient recruitment, side effects, mode of use, etc). Physicians perceived clinic barriers interfered with the pragmatic trial enrollment from the clinic or the healthcare system perspective. This theme covered four subthemes: (1) clinic-related factors, (2) patient-related factors, (3) research personnel, and (4) facilitators (positive factors of the clinic).

Conclusion: Our results from the inductive thematic analysis will help researchers understand the key patient and clinic/system factors/barriers that may influence pragmatic RA trial implementation. The themes suggest there are factors that can be modified (eg, coordinator effort needed, effective patient recruitment during clinic visits, provider engagement) and challenges to overcome (patient insurance status, busy clinic flow, and space issues including limited number of patient rooms). In summary, these themes provide a basis for our and other research teams to develop clinic-centered and patientcentered strategies to implement a pragmatic RA trial.

Objective: The aim of this study is to examine the changes in physical activity level, fatigue, depression, and sleep quality in patients with Behçet's disease during the COVID-19 pandemic.

Methods: The study was designed as an online questionnaire applied to individuals who are being followed up with the diagnosis of Behçet's disease in the rheumatology department. Data were collected using multiple scales including International Physical Activity Questionnaire (IPAQ), Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), Pittsburg Sleep Quality Index (PSQI), and Visual Analogue Scale (VAS) to evaluate physical activity level, fatigue, depression, sleep quality, and pain, respectively.

Results: Sixteen patients diagnosed with Behçet's disease were included in the study. No statistically significant difference was observed between the IPAQ, FSS, BDI, PSQI, and VAS assessment scores before COVID-19 and during COVID-19 period (P > .05 for all).

Conclusion: Thinking of the negative effects of aggressive clinical symptoms, Behçet's disease patients should be supported in physical activity and psychosocial status.

Antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV) are small-vessel vasculitides that include granulomatosis with polyangiitis (formerly Wegener's granulomatosis), microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis (Churg - Strauss syndrome). Renal-limited AAV can be considered a fourth entity. Despite their rarity and still unknown cause(s), research into AAV has been very active over the past decades and has allowed for the development of new therapeutic regimens. The pathogenesis is a complex process of immune dysregulations with genetic and environmental influences. Recent genome-wide association studies have identified multiple genetic predisposing variants, especially at the major histocompatibility complex region. The pathogenic role of antimyeloperoxidase ANCA (MPO-ANCA) is well supported by several animal models, but that of antiproteinase 3 ANCA (PR3-ANCA) is not as strongly demonstrated. B cells likely play a major role in the pathogenesis because they produce ANCAs, as do neutrophil abnormalities, imbalances in T-cell subtypes, and/or cytokine - chemokine networks. The role of the alternative complement pathway was established more recently, and studies of the antagonist of human C5a receptor (avacopan) in AAV have just been completed, with promising results. The current standard management of severe AAV still consists of remission induction therapy with glucocorticoids combined with rituximab or, less often now, cyclophosphamide. Several studies showed that reduced-dose regimens of glucocorticoids are noninferior to the previously used heavier regimens, for therefore less cumulative exposure to glucocorticoids. Avacopan use may even lead to new steroid-free therapeutic approaches, at least for some selected patients. Several trials and studies have now shown the superiority of rituximab over azathioprine or methotrexate as maintenance therapy. However, the optimal dosing regimen and duration for maintenance remain to be better defined, at the individual patient level. Many changes have occurred in the standard of care for AAV over the past decades, and more are expected soon, including with use of avacopan, but also, likely, a few other agents under investigation or development.

Centers for Disease Control and Prevention published a case definition for the multisystem inflammatory syndrome in children in May 2020 when reports started pouring in about a clinical syndrome in children which was temporally associated with coronavirus disease 2019 infection. It has also been referred to as pediatric inflammatory multisystemic syndrome temporally associated with severe acute respiratory syndrome coronavirus 2. Most of these patients test positive for severe acute respiratory syndrome coronavirus 2 serology or reverse transcription-polymerase chain reaction, although a small number of patients could test negative which would require an epidemiological link to the coronavirus disease 2019 infection. The initial clinical presentation could overlap with Kawasaki disease, severe coronavirus disease 2019 infection, toxic shock syndrome, and macrophage activation syndrome. While multisystem inflammatory syndrome in children is characterized by multisystem involvement with hyper inflammation and severe clinical presentation initially, the prognosis is generally good. Since it was first described, there have been multiple studies describing the demographic characteristics, laboratory features, and treatment paradigm.
