Rheumatology: What You May Have Missed in 2023.

Many patients with rheumatologic conditions receive care from physicians other than rheumatologists. Here we note key findings from 6 studies in rheumatology published in 2023 that offer valuable insights for internal medicine specialists and subspecialists outside of rheumatology. The first study investigated the effect of low-dose glucocorticoids on patients with rheumatoid arthritis (RA) over 2 years and challenged existing perceptions about the risks of glucocorticoids in this setting. The second study focused on the updated guideline for preventing and treating glucocorticoid-induced osteoporosis. With the chronic and widespread use of glucocorticoids, the American College of Rheumatology emphasized the importance of assessing fracture risk and initiating pharmacologic therapy when appropriate. The third study explored the potential use of methotrexate in treating inflammatory hand osteoarthritis, suggesting a novel approach to managing this challenging and common condition. The results of the fourth article we highlight suggest that sarilumab has promise as an adjunct treatment of polymyalgia rheumatica relapse during glucocorticoid dosage tapering. The fifth study evaluated sublingual cyclobenzaprine for fibromyalgia treatment, noting both potential benefits and risks. Finally, the sixth article is a systematic review and meta-analysis that assessed the therapeutic equivalence of biosimilars and reference biologics in the treatment of patients with RA. Knowledge of this recent literature will be useful to clinicians regardless of specialty who care for patients with these commonly encountered conditions.

Validation of the 2011 and 2016 American college of rheumatology diagnostic criteria for fibromyalgia in a Chinese population.

PURPOSE: To provide a foundation for clinical diagnosis, epidemiological investigation and intervention trials, we examined the reliability and validity of the American College of Rheumatology (ACR) 2011 and 2016 survey diagnostic criteria among Chinese patients based on the fibromyalgia severity (FS) scale. METHODS: In this study, 200 fibromyalgia patients diagnosed according to the 1990 criteria (1990c) were matched with rheumatoid arthritis (RA) patients based on age and gender. The FS scale score and its subscales were examined to determine their correlations with the revised fibromyalgia impact questionnaire (FIQR). Receiver operator characteristic (ROC) analysis was performed, and test-retest reliability, internal consistency, and construct validity were examined. RESULTS: The area under the curve (AUC) for the ACR 2011c and 2016c was 0.870 and 0.845, respectively, and the sensitivity and specificity were 78.0% and 96.0% for the 2011c and 70.5% and 98.5% for the 2016c, respectively. The FS scale and its subscales were confirmed to exhibit good internal consistency, and they were significantly correlated with the FIQR, thereby indicating adequate construct validity. Using a lower cutoff value 11 points for the FS scale score based on the generalized pain requirement might be a more effective approach in the Chinese population; this approach yielded an AUC of 0.923 and a sensitivity of 87.0% and specificity of 97.5%. CONCLUSION: The 2011c and 2016c are reliable instruments for diagnosing fibromyalgia patients in China. The FS scale could be a valid tool to assist in fibromyalgia diagnosis, and a cutoff value 11 points is more suitable in Chinese patients. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03381131.

The Chinese version of the ACR 2011c and 2016c are valid tools for fibromyalgia diagnosis; and a cutoff value 11 points for FS might be more suitable to assist in fibromyalgia diagnosis in Chinese population. The Chinese 2011c and 2016c for fibromyalgia diagnosis can be found as an appendix to this article.

2022 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for microscopic polyangiitis.

OBJECTIVE: To develop and validate classification criteria for microscopic polyangiitis (MPA). METHODS: Patients with vasculitis or comparator diseases were recruited into an international cohort. The study proceeded in five phases: (1) identification of candidate items using consensus methodology, (2) prospective collection of candidate items present at the time of diagnosis, (3) data-driven reduction of the number of candidate items, (4) expert panel review of cases to define the reference diagnosis and (5) derivation of a points-based risk score for disease classification in a development set using least absolute shrinkage and selection operator logistic regression, with subsequent validation of performance characteristics in an independent set of cases and comparators. RESULTS: The development set for MPA consisted of 149 cases of MPA and 408 comparators. The validation set consisted of an additional 142 cases of MPA and 414 comparators. From 91 candidate items, regression analysis identified 10 items for MPA, 6 of which were retained. The final criteria and their weights were as follows: perinuclear antineutrophil cytoplasmic antibody (ANCA) or anti-myeloperoxidase-ANCA positivity (+6), pauci-immune glomerulonephritis (+3), lung fibrosis or interstitial lung disease (+3), sino-nasal symptoms or signs (-3), cytoplasmic ANCA or anti-proteinase 3 ANCA positivity (-1) and eosinophil count ≥1×109/L (-4). After excluding mimics of vasculitis, a patient with a diagnosis of small- or medium-vessel vasculitis could be classified as having MPA with a cumulative score of ≥5 points. When these criteria were tested in the validation data set, the sensitivity was 91% (95% CI 85% to 95%) and the specificity was 94% (95% CI 92% to 96%). CONCLUSION: The 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for MPA are now validated for use in clinical research.

2022 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for granulomatosis with polyangiitis.

OBJECTIVE: To develop and validate revised classification criteria for granulomatosis with polyangiitis (GPA). METHODS: Patients with vasculitis or comparator diseases were recruited into an international cohort. The study proceeded in five phases: (1) identification of candidate criteria items using consensus methodology, (2) prospective collection of candidate items present at the time of diagnosis, (3) data-driven reduction of the number of candidate items, (4) expert panel review of cases to define the reference diagnosis and (5) derivation of a points-based risk score for disease classification in a development set using least absolute shrinkage and selection operator logistic regression, with subsequent validation of performance characteristics in an independent set of cases and comparators. RESULTS: The development set for GPA consisted of 578 cases of GPA and 652 comparators. The validation set consisted of an additional 146 cases of GPA and 161 comparators. From 91 candidate items, regression analysis identified 26 items for GPA, 10 of which were retained. The final criteria and their weights were as follows: bloody nasal discharge, nasal crusting or sino-nasal congestion (+3); cartilaginous involvement (+2); conductive or sensorineural hearing loss (+1); cytoplasmic antineutrophil cytoplasmic antibody (ANCA) or anti-proteinase 3 ANCA positivity (+5); pulmonary nodules, mass or cavitation on chest imaging (+2); granuloma or giant cells on biopsy (+2); inflammation or consolidation of the nasal/paranasal sinuses on imaging (+1); pauci-immune glomerulonephritis (+1); perinuclear ANCA or antimyeloperoxidase ANCA positivity (-1); and eosinophil count ≥1×109 /L (-4). After excluding mimics of vasculitis, a patient with a diagnosis of small- or medium-vessel vasculitis could be classified as having GPA if the cumulative score was ≥5 points. When these criteria were tested in the validation data set, the sensitivity was 93% (95% CI 87% to 96%) and the specificity was 94% (95% CI 89% to 97%). CONCLUSION: The 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for GPA demonstrate strong performance characteristics and are validated for use in research.

OBJECTIVE: To develop and validate revised classification criteria for eosinophilic granulomatosis with polyangiitis (EGPA). METHODS: Patients with vasculitis or comparator diseases were recruited into an international cohort. The study proceeded in five phases: (1) identification of candidate criteria items using consensus methodology, (2) prospective collection of candidate items present at the time of diagnosis, (3) data-driven reduction of the number of candidate items, (4) expert panel review of cases to define the reference diagnosis and (5) derivation of a points-based risk score for disease classification in a development set using least absolute shrinkage and selection operator logistic regression, with subsequent validation of performance characteristics in an independent set of cases and comparators. RESULTS: The development set for EGPA consisted of 107 cases of EGPA and 450 comparators. The validation set consisted of an additional 119 cases of EGPA and 437 comparators. From 91 candidate items, regression analysis identified 11 items for EPGA, 7 of which were retained. The final criteria and their weights were as follows: maximum eosinophil count ≥1×109/L (+5), obstructive airway disease (+3), nasal polyps (+3), cytoplasmic antineutrophil cytoplasmic antibody (ANCA) or anti-proteinase 3-ANCA positivity (-3), extravascular eosinophilic predominant inflammation (+2), mononeuritis multiplex/motor neuropathy not due to radiculopathy (+1) and haematuria (-1). After excluding mimics of vasculitis, a patient with a diagnosis of small- or medium-vessel vasculitis could be classified as having EGPA if the cumulative score was ≥6 points. When these criteria were tested in the validation data set, the sensitivity was 85% (95% CI 77% to 91%) and the specificity was 99% (95% CI 98% to 100%). CONCLUSION: The 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology Classification Criteria for Eosinophilic Granulomatosis with Polyangiitis demonstrate strong performance characteristics and are validated for use in research.

Analysing cord blood levels of TNF inhibitors to validate the EULAR points to consider for TNF inhibitor use during pregnancy.

BACKGROUND: To minimise placental transfer of tumour necrosis factor inhibitors (TNFi), the European League Against Rheumatism (EULAR) created points to consider (PtC) for the use of TNFi during pregnancy. We are the first to validate the EULAR-PtC by analysing TNFi concentrations in cord blood. METHODS: Patients were derived from the Preconceptional Counselling in Active Rheumatoid Arthritis Study. TNFi was stopped at the time points recommended by the EULAR. Maternal blood and cord blood were collected and analysed for the concentration of TNFi. RESULTS: 111 patients were eligible for the analysis. Median stop time points were gestational age (GA) 37.0 weeks for certolizumab pegol, GA 25.0 weeks for etanercept, GA 19.0 weeks for adalimumab and GA 18.4 weeks for infliximab. Certolizumab pegol (n=68) was detectable in 5.9% of cord blood samples, with a median concentration of 0.3 µg/mL (IQR: 0.2-1.3) and a median cord/maternal concentration ratio of 0.010. Etanercept (n=30) was not detected in any cord blood samples. Adalimumab (n=25) was detectable in 48.0% of cord blood samples, with a median concentration of 0.5 µg/mL (IQR: 0.2-0.7) and a median concentration ratio of 0.062 (IQR: 0.018-0.15). Infliximab (n=14) was detectable in 57.1% of cord blood samples, with a median concentration of 0.4 µg/mL (IQR: 0.1-1.2) and a median concentration ratio of 0.012 (IQR: 0.006-0.081). CONCLUSION: Compliance with the EULAR-PtC results in absence or low levels of TNFi in cord blood.

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.

2021 American College of Rheumatology/Vasculitis Foundation Guideline for the Management of Polyarteritis Nodosa.

OBJECTIVE: To provide evidence-based recommendations and expert guidance for the management of systemic polyarteritis nodosa (PAN). METHODS: Twenty-one clinical questions regarding diagnostic testing, treatment, and management were developed in the population, intervention, comparator, and outcome (PICO) format for systemic, non-hepatitis B-related PAN. 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 16 recommendations and 1 ungraded position statement for PAN. Most recommendations were graded as conditional due to the paucity of evidence. These recommendations support early treatment of severe PAN with cyclophosphamide and glucocorticoids, limiting toxicity through minimizing long-term exposure to both treatments, and the use of imaging and tissue biopsy for disease diagnosis. These recommendations endorse minimizing risk to the patient by using established therapy at disease onset and identify new areas where adjunctive therapy may be warranted. CONCLUSION: These recommendations provide guidance regarding diagnostic strategies, use of pharmacologic agents, and imaging for patients with PAN.

Management of particular clinical situations in psoriatic arthritis: an expert's recommendation document based on systematic literature review and extended Delphi process.

To establish practical recommendations for the management of patients with psoriatic arthritis (PsA) with particular clinical situations that might lead to doubts in the pharmacological decision-making. A group of six expert rheumatologists on PsA identified particular clinical situations in PsA. Then, a systematic literature review (SLR) was performed to analyse the efficacy and safety of csDMARDs, b/tsDMARDs in PsA. In a nominal group meeting, the results of the SLR were discussed and a set of recommendations were proposed for a Delphi process. A total of 65 rheumatologists were invited to participate in the Delphi. Agreement was defined if ≥ 70% of the participants voted ≥ 7 (from 1, totally disagree to 10, totally agree). For each recommendation, the level of evidence and grade of recommendation was established based on the Oxford Evidence-Based Medicine categorisation. Particular clinical situations included monoarthritis, axial disease, or non-musculoskeletal manifestations. The SLR finally comprised 131 articles. A total of 16 recommendations were generated, all but 1 reached consensus. According to them, it is crucial to carefully analyse the impact of individual manifestations on patients (disability, quality of life, etc.), but also to recognise the impact of each drug singularities on selected clinical phenotypes to adopt the most appropriate treatment strategy. Early diagnosis and treatment to target approach, along with a close risk management, is also necessary. These recommendations are intended to complement gaps in national and international guidelines by helping health professionals address and manage particular clinical situations in PsA.

Knowledge gap about immune checkpoint inhibitors among rheumatologists and medical students: a survey.

Previous studies found that physicians working in developed countries in Europe and in the USA declared insufficient knowledge concerning immune-related adverse events (irAE) following use of immune checkpoint inhibitors (ICI) in cancer treatment. We determined this knowledge gap among rheumatologists and medical students (MS) in Brazil. A web-based structured survey or a direct interview was applied to 1428 board-certified Brazilian rheumatologists and an adapted questionnaire was sent to 840 undergraduate MS attending the last 2 years of Medical Schools in Fortaleza-CE, Brazil, in September 2019. 228 (15.9%) rheumatologists and 145 (17.2%) MS answered the survey; 136 (60%) rheumatologists worked at Institutions with Oncology service. Rheumatologists had 22.6 ± 12.6 years of medical practice, most [116 (50.9%)] worked in private practice and 9 (3.9%) were on training. Fifty-three (23.4%) declared being familiar [40 (17.6%)] or very familiar [13 (5.8%)] with irAE. Almost two-thirds declared having never managed irAE and about a third (38.6%) felt confident in managing such patients. Knowledge among rheumatologists was similar regardless of having more or less than 10 years of practice (P = 0.758). Less than 5% MS declared being familiar with ICI and most have never heard of irAE. There is a large gap concerning knowledge about ICI and irAE among rheumatologists and MS in Brazil. Continuing medical education strategies are needed to improve this knowledge.

Treatment of psoriatic arthritis with biologic and targeted synthetic DMARDs: British Society for Rheumatology guideline scope.

The aim of this guideline is to provide an update on evidence-based recommendations for treatment of adult patients with PsA. The previous BSR guidelines for PsA were published in 2012 and since that time, there have been many new advanced therapies licensed for PsA. This update will provide practical guidance for clinicians on the optimal selection of advanced therapies taking into account different domains of PsA (arthritis, enthesitis, dactylitis, axial disease and psoriasis) and key associated comorbidities. It will also update guidance on treatment strategy including the use of a treat-to-target approach. The guideline will be developed using the methods and processes outlined in Creating Clinical Guidelines: Our Protocol. (1) This development process to produce guidance, advice and recommendations for practice has National Institute for Health and Care Excellence (NICE) accreditation.

Insights into the knowledge, attitude and practices for the treatment of idiopathic inflammatory myopathy from a cross-sectional cohort survey of physicians.

The idiopathic inflammatory myopathies (IIM) are heterogeneous and lead to high morbidity and mortality. Knowledge deficits among healthcare professionals could be detrimental to clinical care. Identifying areas of deficient Knowledge, Attitude and Practice (KAP) of IIM can improve physician education and patient outcomes. To assess the proportion of physicians treating IIM with poor KAP and identify the key areas of deficit. An anonymised and validated e-survey (57 questions) was circulated among physicians treating IIM (purposive sampling). Responses were evaluated using the Likert scale for good (> 70% correct response), poor (> 20% chose > 2 answers) and the rest as intermediate consensus. Descriptive statistics were used. Intergroup comparisons were done using non-parametric tests. Of 80 (9.1% of 883) respondents, 90% were rheumatologists and 37.5% academicians. The knowledge base of treating physicians was good in specific domains such as triggers (80-90%), clinical presentation (MDA5, statin myositis, steroid myopathy, anti-synthetase syndrome) (82-92%), IIM mimics (41-89%), investigations (23-92%) and risk of osteoporosis in IIM (79%). There is also an intermediate knowledge base/consensus for outcome measures (30-56%) and response criteria (30-53%). There was poor knowledge and consensus on trials (27-34%), EULAR/ACR criteria (31%) and exercise-based interventions (17-62%). While 90% agree on the need for muscle biopsy to diagnose polymyositis, only one-third advocated it for juvenile and adult DM. Physicians have a good understanding of the triggers, clinical presentation and mimics of IIM. Poor to intermediate knowledge and consensus exists regarding muscle biopsy, outcome measures, response criteria and exercise-based interventions, which could be addressed through future focussed educational initiatives.

[IgG4-related disease: Diagnostic criteria evolution toward the 2019 ACR/EULAR classification criteria]. / Maladie associée aux IgG4 : des critères « diagnostiques ¼ aux critères de classification ACR/EULAR 2019.

The concept of IgG4-related disease (IgG4-RD) has recently been individualized in the early 2000s, but most of the organ involvements are known since more than 100 years. IgG4-RD is a non-malignant fibroinflammatory disorder, characterized by peculiar immunological and pathological abnormalities, which can affect virtually all organs or tissues. Diagnostic criteria have been proposed and have evolved rapidly, with general or organ specific criteria. An international and multidisciplinary group assembled by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) has recently developed and validated a set of classification criteria called 2019 ACR/EULAR classification criteria for IgG4-related disease. The objective of this review is to discuss the evolution from organ specific and general diagnostic criteria toward the 2019 ACR/EULAR classification criteria, as well as respective benefits and limits of these criteria. The use of the 2019 ACR/EULAR classification criteria will help to better define homogeneous group of IgG4-RD patients in future clinical, epidemiological and basic science research studies on the disease.

Atlas of the OMERACT Heel Enthesitis MRI Scoring System (HEMRIS).

OBJECTIVE: Assessment of enthesitis, a key feature in spondyloarthritis (SpA) and psoriatic arthritis (PsA), using objective and sensitive methods is pivotal in clinical trials. MRI allows detection of both soft tissue and intra-osseous changes of enthesitis. This article presents an atlas for the Outcome Measures in Rheumatology (OMERACT) Heel Enthesitis Magnetic Resonance ImagingMRI Scoring System (HEMRIS). METHODS: Following a preliminary selection of potential examples of each grade, as per HEMRIS definitions, the images along with detailed definitions and reader rules were discussed at web-based, interactive meetings between the members of the OMERACT MRI in Arthritis Working Group. RESULTS: Reference images of each grade of the MRI features to be assessed using HEMRIS, along with reader rules and recommended MRI sequences are depicted. CONCLUSION: The presented reference images can be used to guide scoring Achilles tendon and plantar fascia (plantar aponeurosis) enthesitis according to the OMERACT HEMRIS in clinical trials and cohorts in which MRI enthesitis is used as an outcome.

Mixed methods study of clinicians' perspectives on barriers to implementation of treat to target in psoriatic arthritis.

OBJECTIVES: In treat to target (T2T), the patient is treated to reach and maintain specified and sequentially measured goals, such as remission or low disease activity. T2T in psoriatic arthritis (PsA) has demonstrated improved clinical and patient-reported outcomes and is recommended in European guidelines. However, most clinicians do not use T2T in PsA. This study examined the barriers and enablers to implementation in practice. METHODS: Sequential mixed methods comprising a qualitative design (interviews and focus group) to inform a quantitative design (survey). Qualitative data were analysed thematically, and quantitative statistics were analysed descriptively. RESULTS: Nineteen rheumatology clinicians participated in telephone interviews or a face-to-face focus group. An overarching theme 'Complexity' (including 'PsA vs Rheumatoid Arthritis', 'Measurement' and 'Resources') and an underpinning theme 'Changes to current practice' (including 'Reluctance due to organisational factors' and 'Individual determination to make changes') were identified. 153 rheumatology clinicians responded to an online survey. Barriers included limited clinical appointment time to collect outcome data (54.5%) and lack of training in assessing skin disease (35%). Enablers included provision of a protocol (86.4%), a local implementation lead (80.9%), support in clinic to measure outcomes (83.3%) and training in T2T (69.8%). The importance of regular audit with feedback, specialist PsA clinics and a web-based electronic database linked to hospital/national information technology (IT) systems were also identified as enablers. CONCLUSIONS: Implementation of T2T in PsA requires an integrated approach to address the support, training and resource needs of individual clinicians, rheumatology teams, local IT systems and service providers to maximise success.

2020 American College of Rheumatology Guideline for the Management of Gout.

OBJECTIVE: To provide guidance for the management of gout, including indications for and optimal use of urate-lowering therapy (ULT), treatment of gout flares, and lifestyle and other medication recommendations. METHODS: Fifty-seven population, intervention, comparator, and outcomes questions were developed, followed by a systematic literature review, including network meta-analyses with ratings of the available evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, and patient input. A group consensus process was used to compose the final recommendations and grade their strength as strong or conditional. RESULTS: Forty-two recommendations (including 16 strong recommendations) were generated. Strong recommendations included initiation of ULT for all patients with tophaceous gout, radiographic damage due to gout, or frequent gout flares; allopurinol as the preferred first-line ULT, including for those with moderate-to-severe chronic kidney disease (CKD; stage >3); using a low starting dose of allopurinol (≤100 mg/day, and lower in CKD) or febuxostat (<40 mg/day); and a treat-to-target management strategy with ULT dose titration guided by serial serum urate (SU) measurements, with an SU target of <6 mg/dl. When initiating ULT, concomitant antiinflammatory prophylaxis therapy for a duration of at least 3-6 months was strongly recommended. For management of gout flares, colchicine, nonsteroidal antiinflammatory drugs, or glucocorticoids (oral, intraarticular, or intramuscular) were strongly recommended. CONCLUSION: Using GRADE methodology and informed by a consensus process based on evidence from the current literature and patient preferences, this guideline provides direction for clinicians and patients making decisions on the management of gout.

[Autologous hematopoietic stem cell transplantation for systemic sclerosis : Position statement of the stem cell therapy working party of the German Society of Rheumatology]. / Autologe hämatopoetische Stammzelltransplantation bei systemischer Sklerose : Positionspapier des Arbeitskreises Stammzelltherapie der Deutschen Gesellschaft für Rheumatologie.

There have been three randomized controlled trials on autologous hematopoietic stem cell transplantation (AHSCT) in systemic sclerosis (SSc) that demonstrated significant superiority with respect to survival, improvement of cutaneous fibrosis, lung function and quality of life compared to standard treatment; however, these advantages must be carefully weighed against the transplantation-related risks. For this reason, an expert group from the stem cell therapy working party of the German Society for Rheumatology (DGRh) has now developed recommendations for the use of AHSCT in SSc. Based on the high-quality evidence, AHSCT is considered as the standard option for the treatment of selected SSc patients. Potential candidates for AHSCT are those with early, rapidly progressive, diffuse cutaneous SSc with visceral manifestations who have not yet developed severe damage to internal organs. A close cooperation between rheumatologists and transplantation centers is crucial for optimizing patient selection and treatment outcomes.

Treatment guidelines in psoriatic arthritis.

Psoriatic arthritis (PsA) is a complex inflammatory musculoskeletal and skin disease. The treatment of PsA has changed substantially over the past 10 years. Clinical practice guidelines are developed to help busy clinicians rapidly integrate evolving knowledge of therapeutic management into practice. In this review, we compare PsA treatment recommendations or guidelines developed by one national organization [ACR and National Psoriasis Foundation (NPF) in 2018], one regional organization (EULAR in 2015), and one international organization (the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis in 2015). We examine the development of guidelines in PsA more broadly and examine similarities and differences in the three sets of recommendations.
