Efficacy and safety of avacopan in patients with ANCA-associated vasculitis receiving rituximab in a randomised trial.

OBJECTIVES: To evaluate the efficacy and safety of avacopan in the subgroup of patients with antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis receiving background induction therapy with rituximab in the phase 3 ADVOCATE trial. METHODS: Key efficacy outcomes were remission at week 26 and sustained remission at week 52. Additional outcomes included the Glucocorticoid Toxicity Index, estimated glomerular filtration rate, urinary albumin to creatinine ratio, health-related quality of life and safety. RESULTS: Of the 330 patients who received study medication, 214 (64.8%) received rituximab (once weekly for 4 weeks), with a mean age of 59.8 years; 163 (76.2%) had renal vasculitis and 125 (58.4%) were newly diagnosed. Remission at week 26 and sustained remission at week 52 were achieved by 83/107 (77.6%) and 76/107 (71.0%) patients in the avacopan group and 81/107 (75.7%) and 60/107 (56.1%) in the prednisone taper group, respectively. The relapse rate, recovery of renal function, speed of reduction in albuminuria and glucocorticoid toxicity favoured the avacopan group. Serious adverse events occurred in 34.6% and 39.3% of patients in the avacopan and prednisone taper groups, respectively. CONCLUSIONS: These data suggest that in patients with ANCA-associated vasculitis receiving rituximab, efficacy of treatment with avacopan compared with a prednisone taper was similar at week 26 and greater at week 52, with a favourable safety profile. In addition, avacopan was associated with improved renal outcomes and lower glucocorticoid toxicity. These results demonstrate the efficacy and safety of avacopan in patients receiving background induction therapy with rituximab. TRIAL REGISTRATION NUMBER: NCT02994927.

Recommendations for early referral of individuals with suspected polymyalgia rheumatica: an initiative from the international giant cell arteritis and polymyalgia rheumatica study group.

OBJECTIVE: To develop international consensus-based recommendations for early referral of individuals with suspected polymyalgia rheumatica (PMR). METHODS: A task force including 29 rheumatologists/internists, 4 general practitioners, 4 patients and a healthcare professional emerged from the international giant cell arteritis and PMR study group. The task force supplied clinical questions, subsequently transformed into Population, Intervention, Comparator, Outcome format. A systematic literature review was conducted followed by online meetings to formulate and vote on final recommendations. Levels of evidence (LOE) (1-5 scale) and agreement (LOA) (0-10 scale) were evaluated. RESULTS: Two overarching principles and five recommendations were developed. LOE was 4-5 and LOA ranged between 8.5 and 9.7. The recommendations suggest that (1) each individual with suspected or recently diagnosed PMR should be considered for specialist evaluation, (2) before referring an individual with suspected PMR to specialist care, a thorough history and clinical examination should be performed and preferably complemented with urgent basic laboratory investigations, (3) individuals with suspected PMR with severe symptoms should be referred for specialist evaluation using rapid access strategies, (4) in individuals with suspected PMR who are referred via rapid access, the commencement of glucocorticoid therapy should be deferred until after specialist evaluation and (5) individuals diagnosed with PMR in specialist care with a good initial response to glucocorticoids and a low risk of glucocorticoid related adverse events can be managed in primary care. CONCLUSIONS: These are the first international recommendations for referral of individuals with suspected PMR, which complement the European Alliance of Associations for Rheumatology/American College of Rheumatology management guidelines for established PMR.

Clinical Outcomes in Patients with Rheumatoid Arthritis After Switching Between Interleukin-6-Receptor Inhibitors and Janus Kinase Inhibitors: Findings from an Observational Study.

INTRODUCTION: This observational study evaluated response in patients with rheumatoid arthritis (RA) who switched from an interleukin-6 receptor inhibitor (IL-6Ri) to a Janus kinase inhibitor (JAKi) and vice versa. METHODS: Adult patients with RA, who initiated IL-6Ri or JAKi (following discontinuation of JAKi or IL-6Ri, respectively) during/after December 2012 and had a 6-month follow-up visit were enrolled. Clinical outcomes were evaluated at baseline and the follow-up visit. Continuous outcomes included Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire (HAQ), pain, fatigue, tender joint count, swollen joint count, Physician Global Assessment (MDGA), Patient Global Assessment (PtGA), and morning stiffness duration. Categorical outcomes included the proportion of patients achieving CDAI low disease activity (LDA), remission, and minimal clinically important differences (MCIDs) for HAQ, pain, fatigue, MDGA, and PtGA. Continuous outcomes were summarized as mean changes from baseline, and categorical outcomes as response rates. Differences in the outcome measures between groups were evaluated using linear and logistic regression models. RESULTS: Between IL-6Ri (n = 100) and JAKi initiators (n = 129), no significant differences were noted for continuous outcomes. Within both groups, a significant proportion of patients achieved LDA, remission, and MCIDs for other measures, although the odds of achieving LDA were higher among IL-6Ri (vs. JAKi) initiators with moderate-to-severe disease (adjusted odds ratio: 3.30 [1.01, 10.78]). CONCLUSIONS: Patients with RA can achieve improvement in response when switching between IL-6Ri and JAKi. Although both therapies affect the IL-6 pathway, there are distinct mechanisms of action, which likely contribute to their clinical improvement, when reciprocally switched as follow-on treatments.

Treatment Approaches to Granulomatosis with Polyangiitis and Microscopic Polyangiitis.

We have made significant headway in our ability to induce and maintain remission in patients with granulomatosis with polyangiitis and microscopic polyangiitis. With increased understanding of the pathogenesis of antineutrophilic cytoplasmic antibody-associated vasculitides (AAV), therapeutic targets have been identified and studied in clinical trials. From initial induction strategies including glucocorticoids and cyclophosphamide, we have discovered effective induction regimens with rituximab and complement inhibition that can significantly decrease the glucocorticoid cumulative doses in patients with AAV. There are many trials underway evaluating management strategies for refractory patients and exploring new and old therapies that may help to continuously improve outcomes for patients with AAV.

Virtually Speaking: The Impact of a Nationwide Synchronous and Asynchronous Learning Forum.

OBJECTIVE: To address significant disruptions in didactic education precipitated by the COVID-19 pandemic, a group of rheumatology program directors collaborated with the American College of Rheumatology to create a virtual fellows-in-training (V-FIT) program. METHODS: A working group was composed to develop the virtual didactic program comprising live virtual sessions of core curricular rheumatology topics that were recorded to permit asynchronous learning. Nationally recognized educators were invited to lead sessions to fill the void in didactic education occurring on a broad scale across US rheumatology fellowship training programs. Demographic information, live and asynchronous participation data, and feedback surveys were collected from participants in the program. RESULTS: There were 3 components to V-FIT: the Virtual Rheumatology Learning (ViRL) series, the Virtual Rheumatology Practicum (ViP), and the Virtual Rheumatology Teaching Lessons (ViTLs). The ViRL program had global impact with more than 2,000 learners from more than 55 countries. ViP provided a standardized curriculum of rheumatology topics for incoming first-year fellows. ViTLs addressed advanced and interdisciplinary rheumatic disease topics for learners at all stages. CONCLUSION: With collaboration, adaptation, and innovation, the V-FIT program not only maintained but also enhanced education for rheumatology trainees, was enriched by national and international participation, and provided standardized, broadly accessible content with interdisciplinary learning.

Treatment Guidelines in Vasculitis.

The vasculitides encompass a group of inflammatory conditions affecting the blood vessels with severe consequences including tissue ischemia, structural abnormalities, such as aneurysms/dissections, and end organ damage. The different forms are commonly classified based on the size of the blood vessel involved as large-vessel, medium-vessel, and small-vessel vasculitis. The American College of Rheumatology/Vasculitis Foundation recently published guidelines on the management of several forms of primary systemic vasculitides. In this review, the recommendations for giant cell arteritis, Takayasu arteritis, polyarteritis nodosa, granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis are discussed. We highlight the key recommendations, aspects where they diverge from other published guidelines, controversies, and areas of uncertainty.

2021 American College of Rheumatology/Vasculitis Foundation Guideline for the Management of Kawasaki Disease.

OBJECTIVE: To provide evidence-based recommendations and expert guidance for the management of Kawasaki disease (KD), focusing on clinical scenarios more commonly addressed by rheumatologists. METHODS: Sixteen clinical questions regarding diagnostic testing, treatment, and management of KD were developed in the Patient/Population, Intervention, Comparison, and Outcomes (PICO) question format. Systematic literature reviews were conducted for each PICO question. We used the Grading of Recommendations, Assessment, Development and Evaluation method to assess the quality of evidence and formulate recommendations. Each recommendation required consensus from at least 70% of the Voting Panel. RESULTS: We present 1 good practice statement, 11 recommendations, and 1 ungraded position statement to guide the management of KD and clinical scenarios of suspected KD. These recommendations for KD are focused on situations in which input from rheumatologists may be requested by other managing specialists, such as in cases of treatment-refractory, severe, or complicated KD. The good practice statement affirms that all patients with KD should receive initial treatment with intravenous immunoglobulin (IVIG). In addition, we developed 7 strong and 4 conditional recommendations for the management of KD or suspected KD. Strong recommendations include prompt treatment of incomplete KD, treatment with aspirin, and obtaining an echocardiogram in the setting of unexplained macrophage activation syndrome or shock. Conditional recommendations include use of IVIG with other adjuvant agents for patients with KD and high-risk features of IVIG resistance and/or coronary artery aneurysms. These recommendations endorse minimizing risk to the patient by using established therapy promptly at disease onset and identifying situations in which adjunctive therapy may be warranted. CONCLUSION: These recommendations provide guidance regarding diagnostic strategies, use of pharmacologic agents, and use of echocardiography in patients with suspected or confirmed KD.

Rheumatology Milestones 2.0: A Roadmap for Competency-Based Medical Training of Rheumatology Fellows in the 21st Century.

OBJECTIVE: Since 2014, rheumatology fellows have been assessed not only based on their ability to provide patient care and possession of medical knowledge but also on their skill in serving as patient advocates, navigators of health systems, and members of a health care team. Such assessments have been carried out through the use of competency-based milestones from the Accreditation Council of Graduate Medical Education (ACGME). However, a needs assessment has demonstrated interest in more context validity and subspecialty relevance since the development of the ACGME internal medicine (IM) subspecialty reporting milestones. The ACGME thus created a milestones working group, and the present study was undertaken to develop Rheumatology Milestones 2.0 as well as a supplemental guide to assist with implementation. METHODS: The working group, consisting of 7 rheumatology program directors, 2 division directors, a community practice rheumatologist, a rheumatology fellow in training, and a public member who is a rheumatology patient, was overseen by the ACGME vice president for milestones development and met through three 12-hour, in-person meetings to compose the rheumatology specialty milestones and supplemental guide within the ACGME Milestones 2.0 project. RESULTS: Informed by the needs assessment data and stakeholders, the working group revised and adapted the ACGME IM subspecialty reporting milestones to create a rheumatology-specific set of milestones and a supplemental guide for their implementation. CONCLUSION: The Rheumatology Milestones 2.0 provides a specialty-specific, competency-based evaluation tool that can be used by program directors, clinical competency committees, and others to assess the competencies of rheumatology fellows during training and help measure readiness for independent practice.

Telemedicine in Adult Rheumatology: In Practice and in Training.

Many rheumatology providers, including fellows-in-training, responded to the immediate need for maintaining patient access to care via telerheumatology during the COVID-19 pandemic. The rapidity of this transition did not permit an intentional approach to integrating fellow education and training into virtual patient care. Virtual patient care has since become an integrated, and perhaps, an embedded part of rheumatology practice that will likely endure beyond the COVID-19 pandemic. Thus, the development of best practices in telerheumatology, including those for fellow education and training as these new entrants prepare to enter our workforce, will benefit the entire specialty. In this work, we seek to describe current models for training learners in virtual patient care, characterize existing barriers to virtual care models, and offer strategies to integrate telerheumatology into curriculum development and training.

2021 American College of Rheumatology/Vasculitis Foundation Guideline for the Management of Giant Cell Arteritis and Takayasu Arteritis.

OBJECTIVE: To provide evidence-based recommendations and expert guidance for the management of giant cell arteritis (GCA) and Takayasu arteritis (TAK) as exemplars of large vessel vasculitis. METHODS: Clinical questions regarding diagnostic testing, treatment, and management were developed in the population, intervention, comparator, and outcome (PICO) format for GCA and TAK (27 for GCA, 27 for TAK). Systematic literature reviews were conducted for each PICO question. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to rate the quality of the evidence. Recommendations were developed by the Voting Panel, comprising adult and pediatric rheumatologists and patients. Each recommendation required ≥70% consensus among the Voting Panel. RESULTS: We present 22 recommendations and 2 ungraded position statements for GCA, and 20 recommendations and 1 ungraded position statement for TAK. These recommendations and statements address clinical questions relating to the use of diagnostic testing, including imaging, treatments, and surgical interventions in GCA and TAK. Recommendations for GCA include support for the use of glucocorticoid-sparing immunosuppressive agents and the use of imaging to identify large vessel involvement. Recommendations for TAK include the use of nonglucocorticoid immunosuppressive agents with glucocorticoids as initial therapy. There were only 2 strong recommendations; the remaining recommendations were conditional due to the low quality of evidence available for most PICO questions. CONCLUSION: These recommendations provide guidance regarding the evaluation and management of patients with GCA and TAK, including diagnostic strategies, use of pharmacologic agents, and surgical interventions.

2021 American College of Rheumatology/Vasculitis Foundation Guideline for the Management of Antineutrophil Cytoplasmic Antibody-Associated Vasculitis.

OBJECTIVE: To provide evidence-based recommendations and expert guidance for the management of antineutrophil cytoplasmic antibody-associated vasculitis (AAV), including granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). METHODS: Clinical questions regarding the treatment and management of AAV were developed in the population, intervention, comparator, and outcome (PICO) format (47 for GPA/MPA, 34 for EGPA). Systematic literature reviews were conducted for each PICO question. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to assess the quality of evidence and formulate recommendations. Each recommendation required ≥70% consensus among the Voting Panel. RESULTS: We present 26 recommendations and 5 ungraded position statements for GPA/MPA, and 15 recommendations and 5 ungraded position statements for EGPA. This guideline provides recommendations for remission induction and maintenance therapy as well as adjunctive treatment strategies in GPA, MPA, and EGPA. These recommendations include the use of rituximab for remission induction and maintenance in severe GPA and MPA and the use of mepolizumab in nonsevere EGPA. All recommendations are conditional due in part to the lack of multiple randomized controlled trials and/or low-quality evidence supporting the recommendations. CONCLUSION: This guideline presents the first recommendations endorsed by the American College of Rheumatology and the Vasculitis Foundation for the management of AAV and provides guidance to health care professionals on how to treat these diseases.
