EULAR evidence-based and consensus-based recommendations on the management of medium to high-dose glucocorticoid therapy in rheumatic diseases

Egyptian Consensus Guidance for Treatment of Adults with Non-Infectious Uveitis

PURPOSE

Developing and setting up an Egyptian consensus for the management of NIU.

METHODS

A two-phase survey was implemented to obtain expert opinions from Egyptian specialists in the management of non-infectious uveitis. A core team of specialists in management of NIU formulated 21 clinical questions that were structured according to the PICO format (population, intervention, comparison, and the outcome). The literature review team conducted a systemic literature review to address the PICO questions. Based on literature search, a set of 21 sectioned recommendation statements were developed.

RESULTS

The differences in ethnicity and socioeconomic standards of the Egyptian population raised the need to develop an Egyptian consensus guidance for management of NIU. The management statements developed in this work were based on a thorough review of the literature and consensus agreement of a national expert panel. Systemic immunosuppression should be initiated during steroid tapering and should be used as first line along with steroids in case of underlying systemic disease. The panel recommended that maintenance dose of steroids should not exceed 7.5 mg daily. A major limitation facing the Egyptian health system is the socioeconomic status and limited insurance coverage. Hence, the use of conventional immunosuppression is usually exhausted before considering biologic therapy, and the role of biosimilars is emphasized to their relatively lower cost, similar efficacy, and safety in comparison to the original molecule.

CONCLUSION

This guideline provides direction for rheumatologists and ophthalmologists making decisions on management of adults with non-infectious uveitis. Putting into consideration that clinical practice varies based on local pharmaceutical availability and patient demographics.

Management of IgG4-related cholangitis: diagnosis, therapy, and long-term surveillance

IgG4-related cholangitis (IRC) is a chronic cholestatic liver disease that often occurs concomitantly with autoimmune pancreatitis type 1. Both conditions are manifestations of IgG4-related disease, a systemic autoimmune-mediated fibroinflammatory disorder. Patients often present with jaundice and weight loss, mimicking hepatobiliary malignancies, such as cholangiocarcinoma, primary sclerosing cholangitis, and pancreatic cancer. Accurate diagnosis is challenging due to the absence of pathognomonic findings but can be achieved using the HISORt criteria (histology, imaging, serology, other organ involvement, and response to immunosuppressive therapy). Early diagnosis is critical to avoid unnecessary surgery and prevent progression to liver fibrosis or cirrhosis. IRC responds well to corticosteroid therapy, though relapses are common, necessitating long-term immunosuppressive treatment in many cases. Steroid-sparing agents for remission induction and maintenance therapy comprise immunomodulators, such as azathioprine, as well as B-cell depletion therapies, such as rituximab. This review provides a structured clinical overview of the diagnosis, differential diagnosis, and therapy, including novel therapeutic options, such as inebilizumab, for this rare yet severe condition. A key focus is on long-term surveillance strategies, which include laboratory tests, imaging (contrast-enhanced magnetic resonance imaging/magnetic resonance cholangiopancreatography, ultrasound, endosonography), and, particularly in patients with fibrotic bile duct strictures, endoscopy (endoscopic retrograde cholangiopancreatography, cholangioscopy).

Pathway-instructed therapeutic selection of ruxolitinib reduces neuroinflammation in fungal postinfectious inflammatory syndrome

Therapies to reduce neuroinflammation following resolution of acute central nervous system (CNS) infections are urgently needed, particularly for patients with non-HIV-associated cryptococcal meningoencephalitis complicated by a postinfectious inflammatory response syndrome (cPIIRS). To identify druggable targets in cPIIRS, patient cerebral spinal fluid samples underwent transcriptional analysis, revealing a Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway dominance in neuroinflammatory gene signatures. MurinecPIIRS models recapitulated this pathway predominance and treatment with the JAK inhibitor ruxolitinib, confirmed a mechanistic requirement for this pathway in disease pathology. Ruxolitinib treatment improved markers of neuronal damage, reduced activated T cell and myeloid cells, and improved weight. On the basis of these findings, we conducted a first-in-human ruxolitinib treatment of patients with cPIIRS (NCT00001352). Ruxolitinib treatment of six patients led to demonstrated tolerability, reductions in inflammatory biomarkers and activated immune cells, and improved brain imaging. These results advocate for pathway-instructed therapeutics in neuroinflammatory diseases and endorse JAK inhibitors in further clinical studies of cPIIRS.

ORCHESTRA Delphi consensus: diagnostic and therapeutic management of SARS-CoV-2 infection in patients with rheumatological diseases

OBJECTIVES

The clinical management of COVID-19 in immunocompromised patients remains a challenge. This work aimed to develop a consensus to establish recommendations for the clinical, diagnostic, and therapeutic management of patients with rheumatic diseases and COVID-19.

METHODS

A panel of 14 international experts was selected, and Delphi methodology was used for the consensus, after a systematic literature review. Twenty-four questions were formulated and presented to the panel. The experts voted using a 6-point Likert scale (1) 'Strongly disagree' (SD); (2) 'Disagree' (D); (3) 'Somewhat disagree' (SWD); (4) 'Somewhat agree' (SWA); (5) 'Agree' (A); (6) 'Strongly agree' (SA). To establish consensus, simple or cumulative agreement ≥80% was required over a maximum of three rounds. Cumulative agreement was defined as the sum of response percentages on items 1-2 (SD + D); 2-3 (D + SWD); 4-5 (SWA + A); or 5-6 (A + SA), distinguishing a strong degree of agreement (A + SA) or disagreement (SD + D) from a moderate degree of agreement (SWA + A) or disagreement (D + SWD).

RESULTS

After the three rounds, consensus was reached on 23 of the 24 questions and 10 recommendations were made.

DISCUSSION

The Delphi methodology allowed consensus on recommendations in areas with insufficient scientific evidence, which can be considered for decision-making in the management of patients with rheumatological diseases while awaiting better evidence.

Steroid-induced diabetes in lupus nephritis patients: Classic risk factors or a different type of diabetes?

BackgroundGlucocorticoids are frequently employed in systemic lupus erythematosus (SLE) patients and play a critical role in the induction therapy of lupus nephritis (LN), despite their many side effects, including steroid-induced diabetes (SID). Information regarding SID in SLE patients is quite scant.PurposeThe aim of this study was to determine risk factors associated with the development of SID in patients with LN.Research Design A nested case-control study was conducted.Study sampleWe included patients with biopsy-proven LN, who received induction treatment with steroids.Data Collection and/or AnalysisOut of the total of 358 patients, 35 (9.7%) developed SID.ResultsPatients with SID had more metabolic risk factors, including the metabolic score for insulin resistance (METS-IR); more factors related with lupus activity, with higher SLEDAI and SLICC-DI scores; and lower cumulative pre-induction steroid dose. A higher percentage of patients who developed SID received steroid pulses and a lower percentage received antimalarials. After logistic regression, the variables significantly associated with the development of SID were the SLEDAI index (OR 1.25 [95% CI 1.04-1.50], p 0.01), SLICC-DI (OR 4.93 [95% CI 2.14-11.3], p < 0.001), METS-IR (OR 1.17 [95% CI 1.04-1.32], p 0.009), delta METS-IR at 6 months (OR 1.20 [95% CI 1.03-1.39], p 0.01), and the use of antimalarials (OR 0.14, [95% CI 0.02-0.85], p 0.03). After propensity score matching, METS-IR remained a significant predictor of SID. Patients with METS-IR >36.8 were at higher risk (OR: 2.83, 95% CI: 1.09-7.36, p = 0.034).ConclusionsIn conclusion, SDI development in patients receiving induction therapy for LN is associated with both classic metabolic risk factors and SLE-specific factors, and antimalarial use could be associated with a protective effect. Rheumatologists should be aware of this potential complication, in order to implement appropriate management strategies.

Impact of corticosteroids on the efficacy of first-line pembrolizumab plus chemotherapy in patients with advanced non-small-cell lung cancer

Background

Systemic corticosteroids (SCs) are associated with reduced survival in patients with advanced non-small-cell lung cancer (NSCLC) receiving immune checkpoint inhibitor (ICI) monotherapy. However, the current first-line standard of care usually involves combined chemotherapy (CT) and ICIs, and the effect of SCs on survival under combined CT and ICI has never been studied.

Objectives

To investigate the association between SC therapy and survival under CT-ICI in advanced-stage NSCLC patients.

Design

We performed a multicenter retrospective cohort study of all advanced-stage NSCLC patients receiving first-line CT-ICI.

Methods

The primary endpoint was progression-free survival (PFS) according to SC exposure status (⩾10 mg/day), adjusted in a multivariate Cox model for the following confounders: age, performance status, hospital admission prior to treatment, number of metastatic sites, brain metastases, bone metastases, PD-L1 status, and histological subtype. Multivariate analyses also explored the association between dosage and SC exposure duration and PFS.

Results

Of the 193 included patients, 43 (22.3%) were receiving SCs, mainly because of symptomatic brain metastases (in 25/43 cases, 58%). In multivariate analysis, SC therapy at a 10 mg/day threshold was not associated with PFS (hazard ratio (HR) = 1.25, 95% confidence interval (CI) 0.77-2.03, p = 0.35). However, SC dose was negatively associated with PFS (HR = 1.08 per 10 mg/day increment, 95% CI 1.01-1.16, p = 0.01) especially at doses ⩾60 mg/day (HR = 3.27 per 10 mg/day increment, 95% CI 2.01-5.35, p < 0.001). Duration of SC therapy was not associated with PFS (HR = 0.97, 95% CI 0.81-1.15, p = 0.71), but SC therapy ⩾4 weeks prior to CT-ICI was associated with shorter PFS (HR = 1.07, 95% CI: 1.01-1.14, p = 0.028).

Conclusion

In this group of patients receiving first-line CT-ICI for advanced NSCLC, SCs at ⩾60 mg/day were associated with shorter PFS, but lower doses were not. Prolonged SC therapy prior to CT-ICI was associated with shorter PFS. Larger studies are required to confirm these results.

Impact of glucocorticoids on patients' quality of life: a qualitative study assessing face validity and feasibility of the Steroid PRO in patients with inflammatory gastroenterology, respiratory and dermatology conditions

OBJECTIVES

The Steroid PRO is a treatment-specific patient-reported outcome questionnaire which measures the impact of glucocorticoids on health-related quality of life. It has 15 items grouped into 4 domains (Social impact, Impact on Appearance, Psychological Impact and Treatment Concerns). Initially developed and validated in rheumatic diseases, the Steroid PRO demonstrates potential for broader application in patients with other inflammatory conditions. The objective of this study was to assess face validity, content validity and feasibility of the Steroid PRO in (1) patients treated with glucocorticoids for inflammatory respiratory, dermatological and gastroenterological conditions and (2) clinicians working within these specialties in the UK and USA.

DESIGN

Qualitative study with semistructured cognitive interview methods.

SETTING

Online or face-to-face interviews with participants from seven departments across three secondary care hospitals in the UK and USA.

PARTICIPANTS

Inclusion criteria: (1) Adult patients with inflammatory respiratory, gastroenterological and dermatological conditions treated with glucocorticoids and (2) healthcare professionals (HCPs) working in respiratory, dermatology and gastroenterology departments in the UK and USA.

RESULTS

Purposive sampling to ensure a range of patient and HCP participants. A total of 42 patient participants were recruited, from respiratory/pulmonology (n=14, 33.3%), dermatology (n=13, 31.0%) and gastroenterology (n=15, 35.8%) medical departments; 32 in the UK and 10 from the USA. Mean age 48.2 years (range 22-71) and 19 (45.2%) were female. Patient participants had a range of inflammatory lung, skin and bowel conditions, with a spectrum of demographics and patterns of glucocorticoid use. 14 HCPs participated from the UK (9) and USA (5). Face validity: 97% (30/31) patients and 100% (14/14) HCPs reported the Steroid PRO was 'relevant or very relevant' to them and their disease.

FEASIBILITY

97% (30/31) patients and 100% (14/14) HCPs reported the Steroid PRO was 'easy or very easy to complete'. Patients reported that the four domains of the Steroid PRO had relevance to them and that it was validating to see their concerns represented: 'It's obvious you guys know what you're talking about-these are my issues. It's very validating when you realise it's not just you. These problems are real and they matter.… These are not questions my doctor asks me about. Doctors never ask about psychosocial aspects. It would be really great if they used this' (female patient with asthma). Patients and clinicians felt the Steroid PRO would be suitable for use in clinical practice within their specialties and would aid in understanding of the impact of glucocorticoids.

CONCLUSIONS

The Steroid PRO demonstrated face validity and content validity for assessing the impact of glucocorticoids in patients with inflammatory respiratory, gastroenterological and dermatological conditions. Additionally, the feasibility of using the Steroid PRO with both patients and HCPs has been established. Future work should include quantitative testing of the Steroid PRO as an outcome measure within clinical trials in these conditions.

Evaluating Avacopan in the Treatment of ANCA-Associated Vasculitis: Design, Development and Positioning of Therapy

Recently, avacopan has been approved for the treatment of ANCA-associated vasculitis (AAV). Avacopan is an inhibitor of the C5a-receptor, which plays an important role in chemotaxis and the amplification loop of inflammation in AAV. In the most recent, international guidelines avacopan is recommended as steroid-sparing agents for the management of AAV. Here, we review the clinical trials that have led to demonstrate that avacopan is an effective treatment option in the management of AAV, where it can significantly reduce the cumulative dosage of glucocorticoids (GC). Despite the new guideline recommendations, clear guidance on how to employ avacopan in real-world clinical practice is lacking. We therefore also address in this review the data and clinical experience with avacopan obtained from real-world evidence. Combining preclinical studies, clinical trials, and real-world evidence helps to provide a better position of avacopan for the management of AAV in routine clinical practice, taking advantage of the GC-sparing effects of avacopan as a possible solution for the current challenge of reducing GC-toxicity in AAV patients. Furthermore, we delineate current knowledge gaps and future research areas that need to be addressed.

Duration of Disease and Long-Term Outcomes in Patients With Difficult-To-Treat Recurrent Pericarditis: A Chronic Condition Treated With Nonsteroidal Anti-Inflammatory Drugs, Colchicine, Corticosteroids, and Anti-Interleukin-1 Agents

OBJECTIVE

We aimed to investigate the remission rate and disease duration in idiopathic or post-cardiac injury pericarditis and risk factors for disease duration and anti-interleukin-1 (IL-1) agent discontinuation.

METHODS

This was a multicenter, longitudinal, observational study including 370 patients (51.4% female). The remission rate was the proportion of patients who stopped all pericarditis-related therapies for at least 6 months without recurrences.

RESULTS

The median follow-up was 4.9 (interquartile range [IQR] 2.8-8.4) years, and the median age at the end of follow-up was 49 (IQR 37-60) years. A median of 1.1 (IQR 0.6-1.9) recurrences/year and 0.4 (IQR 0.1-0.9) hospitalizations/year were recorded. The remission rate at follow-up was 34.0%, 7% per year. Disease duration was shorter for patients in remission (3.1 years, IQR 1.6-6.2 years) than for those still receiving treatment (4 years, IQR 2.2-7.8; P = 0.02). Use of "guidelines-based therapy" (hazard ratio [HR] 1.85, 95% confidence interval [CI] 1.25-2.73; P = 0.02) and colchicine use at first attack (HR 1.51, 95% CI 1.02-2.23; P = 0.038) were protective factors, whereas steroid use was associated with longer disease duration (HR 0.53, 95% CI 0.35-0.81; P = 0.003). Corticosteroids were used in 77.3% of patients, with a median duration of therapy of 1.1 (IQR 0.4-2.6) years. Anakinra was used in 25.9% with a median duration of therapy of 2.4 (IQR 0.9-5.0) years; only 19.8% were able to stop anakinra at the end of observation period.

CONCLUSION

This study reports the largest and longest follow-up in patients with recurrent pericarditis. Guideline adherence from the first attack is associated with a shorter course. The disease was long and impacting in terms of recurrences and hospitalizations, often requiring a long-term treatment, in particular with anti-IL-1 agents.

Recommendations for the diagnosis and treatment of anti-neutrophil cytoplasmic autoantibody associated vasculitis

Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is characterised by small vessel necrotising inflammatory vasculitis. Prior to immunosupressant therapy availability it usually led to a fatal outcome. Current treatment has changed ANCA-associated vasculitis into a condition with a significant response rate, although with a not negligible relapse occurrence and cumulative organ lesions, mostly due to drug-related toxicities. The use of glucocorticoids, cyclophosphamide and other immunosupressants (such as azathioprine, mychophenolate and methotrexate) was optimised in a series of clinical trials that established the treatment of reference. In recent years, a better knowledge of B lymphocyte function and the role of complement inhibition has transformed the course of this disease while minimising treatment-related adverse effects. This multidisciplinary document of recommendations is based on the consensus of three scientific societies (Internal Medicine, Nephrology and Rheumatology) and on the best available evidence on diagnosis, treatment and follow-up of patients with ANCA-associated vasculitis, including some special situations. The aim of this document is to provide updated information and well-grounded clinical recommendations to practising physicians as to how to improve the diagnosis and treatment outcome of our patients.

Targeting APJ drives BNIP3-PINK1-PARKIN induced mitophagy and improves systemic inflammatory bone loss

INTRODUCTION

Inflammatory diseases, such as diabetes mellitus, rheumatoid arthritis, and inflammatory bowel disease, lead to systemic immune microenvironment disturbances, contributing to bone loss, yet the mechanisms by which specific receptors regulate this process in inflammatory bone loss remain poorly understood. As a G-protein-coupled receptor, the Apelin receptor plays a crucial role in the regulation of inflammation and immune microenvironment. However, the precise mechanisms governing its role in inflammatory bone loss remain incompletely understood.

OBJECTIVE

This study aims to investigate how APJ regulates macrophage polarization to mitigate inflammatory bone loss.

METHODS

Lipopolysaccharide induced systemic inflammatory bone loss model in mice was used to explore the relationship between bone loss and osteoclast activation, macrophage polarization and APJ. In vitro studies, Bone marrow derived macrophages and siRNA were used to elucidate the regulatory influence of APJ on the immune microenvironment and osteoclast differentiation, while high-throughput sequencing is leveraged to uncover the underlying mechanisms through which APJ modulates macrophage polarization.

RESULTS

Our study established a link between APJ and macrophage M1 polarization in systemic inflammatory bone loss mice. The activation of APJ effectively mitigated M1 polarization in macrophages, suppressed excessive osteoclast activation, and alleviated systemic inflammatory bone loss. In vitro high-throughput sequencing analysis revealed that APJ modulates macrophage polarization, linking to mitochondrial autophagy and the NOD-like receptor signaling pathway and the involvement of the AMPK and MAPK signaling pathways in signal transduction after APJ activation was also suggested. Subsequent experiments substantiated that APJ predominantly enhances mitophagy and diminishes the accumulation of reactive oxygen species by regulating the AMPK/BNIP3/PINK1/PARKIN axis, thereby suppressing the activation of macrophage M1 polarization and osteoclastogenesis.

CONCLUSION

This study elucidated the underlying mechanism by which APJ modulates macrophage polarization, thereby proposing a new therapeutic target for addressing inflammatory bone loss.

Role of Avacopan on Antineutrophil Cytoplasmic Antibody (ANCA)-Associated Vasculitis

Antineutrophil cytoplasmic antibody-associated (ANCA) vasculitis are a group of autoimmune diseases characterized by inflammation of the microvasculature, leading to life-threatening complications, including kidney disease. These diseases are associated with a high morbidity and mortality rate. Conventional treatment modalities have evolved towards personalized therapies intending to mitigate inflammation and minimize the adverse effects of traditional immunosuppressive agents. Avacopan, a novel C5a receptor inhibitor, represents a promising therapeutic option for vasculitis with renal involvement. This article provides a comprehensive review of the role of complement in the pathogenesis of vasculitis with renal involvement and the role of avacopan for its treatment, taking into account recent updates to both the EULAR and KDIGO guidelines and published experience of avacopan use in real clinical settings.

Glucocorticoids treatment and adverse infectious events in rheumatic diseases

It is well known that rheumatic diseases are characterized by an increased infection risk, due to several factors, such as an intrinsically dysfunctional immune system, disease activity, and the use of immunosuppressive drugs. Glucocorticoids are widely used therapeutic agents for treating several chronic inflammatory and immune diseases, due to their anti-inflammatory and immunosuppressive effects. Their use is burdened by well-known side effects in dose- and duration of use-dependent manner. Physicians need to be aware of the mechanism of action of glucocorticoids, their side effects, particularly infectious side effects, and the significance of cumulative dose and duration of glucocorticoid treatment. Additionally, physicians shoultdleveld have knowledge of each patient and their comorbidities. They could use appropriate tools for assessing glucocorticoid-related toxicity and morbidity, particularly in the context of chronic glucocorticoid administration. This comprehensive understanding is crucial for ensuring the proper and safe use of these drugs, particularly in terms of minimizing infectious risks. The aim of this review is to focus on available data concerning the infectious risk associated to glucocorticoid treatment in rheumatic diseases, highlighting the role of the correct drug management in clinical practice and the role of the disease itself in the occurrence of this worthy side effect. We conducted a review of randomized controlled trials and observational studies about glucocorticoid use in autoimmune/rheumatic diseases, analyzing the infectious risk during glucocorticoid therapy, and its relationship with the used dose and duration of treatment.

Corticosteroid therapy in older adults with cancer: Expert recommendations from a task force of the International Society of Geriatric Oncology

Corticosteroids are used frequently in oncology and many patients require short- or long-term corticosteroid therapy. General clinical guidelines and recommendations exist on the use of corticosteroids; however, evidence is lacking for recommendations on their appropriate use in older adult with cancer. Treatment of chemotherapy-induced nausea and vomiting (CINV) has dramatically improved over the last decade with 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists and neurokinin-1 (NK-1) receptor antagonists or a combination of both. However, corticosteroids continue to play an important role in the management of acute and delayed CINV prevention. While highly efficacious, the toxicity profile of corticosteroids must be considered, particularly in heterogeneous older patients with multiple comorbidities and polypharmacy. Guidance on corticosteroid-reducing/sparing strategies in this specific population is needed. This consensus, supported by the International Society of Geriatric Oncology, aims to provide evidence-based recommendations for the use of corticosteroid therapy in older adults with cancer.

[Long-term goflkicept therapy for patients with idiopathic recurrent pericarditis: results of the interim analysis of an ongoing open-label extension study]

AIM

To evaluate the long-term safety and efficacy of goflkicept treatment in patients with idiopathic recurrent pericarditis (IRP).

MATERIALS AND METHODS

This report presents the interim analysis of an ongoing open-label extension (OLE) clinical trial of goflkicept in patients with IRP (NCT05673902), as a continuation of the core study (NCT04692766). The study assessed the frequency of pericarditis recurrence, time to recurrence after 12 and 60 weeks of goflkicept therapy, changes in C-reactive protein level, chest pain intensity, pericardial effusion size, and adverse events (AEs).

RESULTS

All patients remained in clinical-laboratory remission during the 60 weeks of goflkicept treatment. The recurrence frequency was 31.3% (5/16) after 60 weeks and 90% (9/10) after 12 weeks of goflkicept treatment (p<0.001). A total of 64 AEs were reported in 16 patients (94.1%), mostly of mild to moderate severity. The most common AEs were infections, occurring in 11 patients (64.7%). Nine serious adverse events were reported in 5 patients, none of which were considered drug-related. There were no deaths.

CONCLUSION

Long-term goflkicept therapy resulted in a significant reduction in the risk of recurrence and prolonged remission without an increase in adverse events.

CX-5461 ameliorates disease in lupus-prone mice by triggering B-cell ferroptosis via p53-SLC7A11-ALOX12 pathway

CX-5461, a first-in-class compound, is widely recognized as a selective inhibitor of RNA polymerase I. Recently, it has been reported to possess novel immunosuppressive properties with significant therapeutic effects in transplantation immune rejection. However, the potential use of CX-5461 for Systemic Lupus Erythematosus (SLE) treatment remains unknown. In this study, we elucidated the mechanism underlying the therapeutic efficacy of CX-5461 in lupus. Our findings demonstrated that CX-5461 selectively targets B cells and effectively reduces the proportions of B cells, germinal center B cells, and plasma cells in MRL/MPJ-Faslpr and Resiquimod (R848)-induced lupus mice. Molecular studies revealed that CX-5461 modulates CD36-Acyl-CoA Synthetase Long Chain Family Member 4 (ACSL4)-mediated glycerolipid metabolism in B cells, triggering ferroptosis through the p53- Solute Carrier Family 7 Member 11 (SLC7A11)- Arachidonate 12-Lipoxygenase (ALOX12) pathway, thereby decreasing IgG and Anti-Double-Stranded Deoxyribonucleic Acid (dsDNA) antibody levels and attenuating lupus. Collectively, these results suggest that CX-5461 holds promise as an effective candidate for targeted therapy against lupus.

Addressing Glucocorticoid-Related Problems with the Clinical Pharmacist Collaboration in Rheumatology Practice: A Prospective Follow-Up Study

INTRODUCTION

Glucocorticoids (GCs) play a crucial role in the treatment of many rheumatic diseases regarding their anti-inflammatory and immunosuppressive effects. Inappropriate use of GCs can exacerbate GC-related problems besides complex treatment regimens and miscellaneous well-established adverse events. Although several guidelines exist for managing these problems, there is lack of real-life studies evaluating the problems at the patient level. This study aims to identify GC-related problems among patients with rheumatic diseases and address how they have been solved.

METHODS

This prospective follow-up study was conducted between January 2021 and June 2022 at a university rheumatology outpatient clinic and included patients using GCs. A clinical pharmacist assessed patients for possible GC-related problems at baseline, 3 months, and 6 months. Identified problems, their causes, interventions to address these problems, and their outcomes were categorized using the Pharmaceutical Care Network Europe (PCNE v9.1) classification system. The resolution of the problems was evaluated at the patient's next follow-up visit.

RESULTS

A total of 156 patients were included, and 236 GC-related problems were identified in 66% of the patients. Adverse drug events (possible) accounted for the highest proportion of GC-related problems (94.1%), and the most common causes were lack of laboratory monitoring of GC-related adverse events (41.5%) and lack of drug treatment despite existing indications (39.8%). The median cumulative prednisolone dose was higher in patients with GC-related problems (3115 vs. 5455 mg, p = 0.007). The clinical pharmacist suggested 381 interventions: 47.7% (n = 182) at the 'prescriber level', 31.8% (n = 121) at the 'patient level', and 20.5% (n = 78) at the 'drug level'. Of those interventions, 98% were accepted, and 80.1% of the problems were solved.

CONCLUSIONS

This study showed that the prevalence of GC-related problems is high in patients with rheumatic diseases. Integrating clinical pharmacists into the multidisciplinary rheumatology team provides an advantage in effectively identifying and managing GC-related problems at an early stage.

ANCA-associated vasculitis-treatment standard

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are characterized by small-vessel necrotizing inflammation, and prior to the advent of immunosuppressive therapy frequently had a fatal outcome. Treatment has transformed AAV into a relapsing/remitting disease with increased drug-related toxicities and organ damage. The use of glucocorticoids, cyclophosphamide and immunosuppressives (including azathioprine, mycophenolate and methotrexate) was optimized through a sequence of clinical trials establishing a standard of care against which subsequent targeted therapies could be developed. Improved understanding of pathophysiology has supported the development of B-cell depletion and complement inhibition in granulomatosis with polyangiitis and microscopic polyangiitis, and interleukin 5 inhibition for eosinophilic granulomatosis with polyangiitis, leading to the approval of newer agents for these conditions. There has been an increased attention on minimizing the adverse effects of treatment and on understanding the epidemiology of comorbidities in AAV. This review will focus on recent evidence from clinical trials, especially with respect to glucocorticoids, avacopan, plasma exchange, rituximab and mepolizumab, and their interpretation in the 2022 management recommendations by the European League of Associations of Rheumatology.

Consensus of the definitions of the OMERACT glucocorticoid impact core domain set for people with rheumatic and musculoskeletal diseases

BACKGROUND

The Outcome Measures in Rheumatology (OMERACT) Glucocorticoid (GC) Impact Working Group has been working to develop a core domain set to measure the impact of GCs on patients living with rheumatic and musculoskeletal diseases. The mandatory domains previously identified for inclusion in all clinical trials measuring the GC effects include infection, bone fragility, mood disturbance, hypertension, diabetes, weight, fatigue, and mortality. Before progressing to instrument selection, the Working Group sought to establish precise definitions of all mandatory domains within the core domain set.

METHODS

OMERACT methodology was applied with the use of evidence and consensus-based decision making of all stakeholder groups (patient research partners, health care professionals, clinician researchers, industry members and methodologists) to develop detailed definitions for the broad domain, target domain and domain components, taking into consideration sources of variability that could affect measurement of the domain.  The working group synthesized prior qualitative studies, quantitative work, and results from Delphi rounds, to develop a rich definition of 'what' is to be measured.

RESULTS

Between 2021 and 2023, the OMERACT Working Group on GC Impact conducted virtual meetings to establish domain definitions. First, we mapped each domain onto an OMERACT Core Area. All domains were primarily represented within the Pathophysiological Manifestations Core Area, except from Fatigue which was primarily Life Impact and Weight which spanned both Core Areas. Sources of variability included cultural factors, age, gender, education level, socioeconomic status, personal experiences, emotional state, and language barriers. The domain definitions will form the foundation for instrument selection and the initial step of domain / concept match and content validity in the OMERACT pillar of 'truth' before moving on to feasibility and discrimination.

CONCLUSION

The OMERACT GC Impact Working Group has developed and agreed upon detailed domain definitions for core domains. Future steps of the working group are to select instruments and develop the core outcome measurement set for clinical trials measuring the impact of GC on patients with rheumatic and musculoskeletal diseases.

JAK/STAT Signaling Predominates in Human and Murine Fungal Post-infectious Inflammatory Response Syndrome

Post-infection inflammatory syndromes have been increasingly recognized as a cause of host damage in a variety of infectious diseases including tuberculosis, bacterial meningitis, and COVID-19. Recently, a post-infectious inflammatory response syndrome (PIIRS) was described in non-HIV-infected cryptococcal fungal meningoencephalitis (CM) as a major cause of mortality. Inflammatory syndromes are particularly severe in neurological infections due to the skull's rigid structure which limits unchecked tissue expansion from inflammatory-induced edema. In the present studies, neurologic transcriptional pathway analysis utilizing a murine PIIRS model demonstrated a predominance of Janus kinase/signal transducer and activator of transcription (JAK/STAT) activation. JAK/STAT inhibitor treatment resulted in improvements in CNS damage markers, reductions in intrathecal CD44hiCD62lo CD4+ effector CD4+ T-cells and MHC II+ inflammatory myeloid cells, and weight gains in mice, the latter after treatment with antifungals. Based on these data, pathway-driven steroid-sparing human treatment for steroid-refractory PIIRS was initiated using short courses of the JAK/STAT inhibitor ruxolitinib. These were well tolerated and reduced activated HLA-DR+ CD4+ and CD8+ cells and inflammatory monocytes as well as improved brain imaging. Together, these findings support the role of JAK/STAT in PIIRS as well as further study of JAK/STAT inhibitors as potential adjunctive therapy for PIRS and other neural inflammatory syndromes.

The effects of suppressing inflammation by tofacitinib may simultaneously improve glycaemic parameters and inflammatory markers in rheumatoid arthritis patients with comorbid type 2 diabetes: a proof-of-concept, open, prospective, clinical study

BACKGROUND

A consistent connection has been increasingly reported between rheumatoid arthritis (RA), insulin resistance (IR), and type 2 diabetes (T2D). The β-cell apoptosis induced by pro-inflammatory cytokines, which could be exaggerated in the context of RA, is associated with increased expression pro-apoptotic proteins, which is dependent on JAnus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) activation. On these bases, we aimed to evaluate if the administration of tofacitinib, a potent and selective JAK inhibitor, could simultaneously improve glycaemic parameters and inflammatory markers in patients with RA and comorbid T2D.

METHODS

The primary endpoint was the change in the 1998-updated homeostatic model assessment of IR (HOMA2-IR) after 6 months of treatment with tofacitinib in RA patients with T2D. Consecutive RA patients with T2D diagnosis were included in this proof-of-concept, open, prospective, clinical study, which was planned before the recent emergence of safety signals about tofacitinib. Additional endpoints were also assessed regarding RA disease activity and metabolic parameters.

RESULTS

Forty consecutive RA patients with T2D were included (female sex 68.9%, mean age of 63.4 ± 9.9 years). During 6-month follow-up, a progressive reduction of HOMA2-IR was observed in RA patients with T2D treated with tofacitinib. Specifically, a significant effect of tofacitinib was shown on the overall reduction of HOMA2-IR (β =  - 1.1, p = 0.019, 95%CI - 1.5 to - 0.76). Also, HOMA2-β enhanced in these patients highlighting an improvement of insulin sensitivity. Furthermore, although a longer follow-up is required, a trend in glycated haemoglobin reduction was also recorded. The administration of tofacitinib induced an improvement in RA disease activity, and a significant reduction of DAS28-CRP and SDAI was observed; 76.8% of patients achieved a good clinical response. In this study, no major adverse events (AEs) were retrieved without the identification of new safety signals. Specifically, no life-threatening AEs and cardiovascular and/or thromboembolic events were recorded.

CONCLUSIONS

The administration of tofacitinib in RA with T2D led to a simultaneous improvement of IR and inflammatory disease activity, inducing a "bidirectional" benefit in these patients. However, further specific designed and powered studies are warranted to entirely evaluate the metabolic effects of tofacitinib in RA patients with T2D.

EULAR recommendations for the management of ANCA-associated vasculitis: 2022 update

BACKGROUND

Since the publication of the EULAR recommendations for the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in 2016, several randomised clinical trials have been published that have the potential to change clinical care and support the need for an update.

METHODS

Using EULAR standardised operating procedures, the EULAR task force undertook a systematic literature review and sought opinion from 20 experts from 16 countries. We modified existing recommendations and created new recommendations.

RESULTS

Four overarching principles and 17 recommendations were formulated. We recommend biopsies and ANCA testing to assist in establishing a diagnosis of AAV. For remission induction in life-threatening or organ-threatening AAV, we recommend a combination of high-dose glucocorticoids (GCs) in combination with either rituximab or cyclophosphamide. We recommend tapering of the GC dose to a target of 5 mg prednisolone equivalent/day within 4-5 months. Avacopan may be considered as part of a strategy to reduce exposure to GC in granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA). Plasma exchange may be considered in patients with rapidly progressive glomerulonephritis. For remission maintenance of GPA/MPA, we recommend rituximab. In patients with relapsing or refractory eosinophilic GPA, we recommend the use of mepolizumab. Azathioprine and methotrexate are alternatives to biologics for remission maintenance in AAV.

CONCLUSIONS

In the light of recent advancements, these recommendations provide updated guidance on AAV management. As substantial data gaps still exist, informed decision-making between physicians and patients remains of key relevance.

IgG4-related cholangitis - a mimicker of fibrosing and malignant cholangiopathies

IgG4-related cholangitis (IRC) is the major hepatobiliary manifestation of IgG4-related disease (IgG4-RD), a systemic fibroinflammatory disorder. The pathogenesis of IgG4-RD and IRC is currently viewed as multifactorial, as there is evidence of a genetic predisposition while environmental factors, such as blue-collar work, are major risk factors. Various autoantigens have been described in IgG4-RD, including annexin A11 and laminin 511-E8, proteins which may exert a partially protective function in cholangiocytes by enhancing secretion and barrier function, respectively. For the other recently described autoantigens, galectin-3 and prohibitin 1, a distinct role in cholangiocytes appears less apparent. In relation to these autoantigens, oligoclonal expansions of IgG4+ plasmablasts are present in patients with IRC and disappear upon successful treatment. More recently, specific T-cell subtypes including regulatory T cells, follicular T helper 2 cells, peripheral T helper cells and cytotoxic CD8+ and CD4+ SLAMF7+ T cells have been implicated in the pathogenesis of IgG4-RD. The clinical presentation of IRC often mimics other biliary diseases such as primary sclerosing cholangitis or cholangiocarcinoma, which may lead to inappropriate medical and potentially invalidating surgical interventions. As specific biomarkers are lacking, diagnosis is made according to the HISORt criteria comprising histopathology, imaging, serology, other organ manifestations and response to therapy. Treatment of IRC aims to prevent or alleviate organ damage and to improve symptoms and consists of (i) remission induction, (ii) remission maintenance and (iii) long-term management. Glucocorticosteroids are highly effective for remission induction, after which immunomodulators can be introduced for maintenance of remission as glucocorticosteroid-sparing alternatives. Increased insight into the pathogenesis of IRC will lead to improved diagnosis and novel therapeutic strategies in the future.

The assessment of atlantoaxial joint involvement in patients with rheumatoid arthritis, results from an observational "real-life" study

Atlantoaxial joint is a possible affected site during rheumatoid arthritis (RA) and, in this work, we evaluated its occurrence and associated characteristics in a "real-life" cohort. By a medical records review study of RA patients longitudinally followed-up, the occurrence of severe atlantoaxial joint involvement was estimated (incidence proportion and incidence rate per 1000 person-years at risk). Regression analyses were also exploited to evaluate possible associated factors. Based on these findings, a prospective recruitment was performed to build a descriptive cross-sectional study in evaluating a subclinical atlantoaxial joint involvement in patients with the same clinical characteristics. Retrospectively, 717 patients (female 56.6%, age 64.7 ± 12.3 years) were studied. The incidence proportion of severe atlantoaxial joint involvement was 2.1% [1.5-2.5], occurring in 15 out of 717 patients, and identified by both MRI and CT scan. Considering over 3091 person-years, an incidence rate of 5.2 × 1000 [2.9-8.3] person-years was estimated. Regression analyses suggested that male gender, a longer disease duration, ACPA positivity and extra-articular manifestations resulted to be significantly associated with a severe atlantoaxial joint involvement. Given these findings, 30 asymptomatic patients were selected according to these clinical characteristics and underwent MRI of cervical spine. To date, almost 50% of these asymptomatic patients showed a subclinical atlantoaxial joint involvement. The occurrence of the severe atlantoaxial joint involvement in RA patients was estimated in a "real-life" setting. Male gender, ACPA positivity, long disease duration, and extra-articular manifestations could be associated with the severe atlantoaxial joint involvement in RA. MRI could provide a useful clinical tool to early evaluate the atlantoaxial joint involvement in RA, also in asymptomatic patients.

Treating the Side Effects of Exogenous Glucocorticoids; Can We Separate the Good From the Bad?

It is estimated that 2% to 3% of the population are currently prescribed systemic or topical glucocorticoid treatment. The potent anti-inflammatory action of glucocorticoids to deliver therapeutic benefit is not in doubt. However, the side effects associated with their use, including central weight gain, hypertension, insulin resistance, type 2 diabetes (T2D), and osteoporosis, often collectively termed iatrogenic Cushing's syndrome, are associated with a significant health and economic burden. The precise cellular mechanisms underpinning the differential action of glucocorticoids to drive the desirable and undesirable effects are still not completely understood. Faced with the unmet clinical need to limit glucocorticoid-induced adverse effects alongside ensuring the preservation of anti-inflammatory actions, several strategies have been pursued. The coprescription of existing licensed drugs to treat incident adverse effects can be effective, but data examining the prevention of adverse effects are limited. Novel selective glucocorticoid receptor agonists and selective glucocorticoid receptor modulators have been designed that aim to specifically and selectively activate anti-inflammatory responses based upon their interaction with the glucocorticoid receptor. Several of these compounds are currently in clinical trials to evaluate their efficacy. More recently, strategies exploiting tissue-specific glucocorticoid metabolism through the isoforms of 11β-hydroxysteroid dehydrogenase has shown early potential, although data from clinical trials are limited. The aim of any treatment is to maximize benefit while minimizing risk, and within this review we define the adverse effect profile associated with glucocorticoid use and evaluate current and developing strategies that aim to limit side effects but preserve desirable therapeutic efficacy.

Measuring the impact of steroid therapy on health-related quality of life in patients with rheumatic diseases: international development of a glucocorticoid treatment-specific patient-reported outcome measure

OBJECTIVES

Glucocorticoids (GCs) ('steroids') are used to treat rheumatic diseases but adverse effects are common. We aimed to explore the impact of GC therapy on health-related quality of life (HRQoL), to inform the development of a treatment-specific patient-reported outcome measure (PROM) for use in clinical trials and practice.

METHODS

Semi-structured qualitative interviews were conducted with patients from the UK, USA and Australia, treated for a rheumatic condition with GCs in the last 2 years. Purposive sampling was used to select participants with a range of demographic and disease features. An initial conceptual framework informed interview prompts and cues. Interviews elicited GC-related physical and psychological symptoms and salient aspects of HRQoL in relation to GC therapy. Interview data were analysed inductively to develop initial individual themes and domains. Candidate questionnaire items were developed and refined.

RESULTS

Sixty semi-structured qualitative interviews were conducted (UK n = 34, USA n = 10, Australia n = 16). The mean age was 58 years; 39/60 were female; and 18 rheumatic diseases were represented. Some 126 individual themes were identified and organized into six domains: physical symptoms; psychological symptoms; psychological impact of steroids; impact of steroids on participation; impact of steroids on relationships; and benefits of steroids. Candidate questionnaire items were tested and refined by piloting with patient research partners, iterative rounds of cognitive interviews and linguistic translatability assessment, informing a draft questionnaire.

CONCLUSION

We describe an international qualitative study to develop candidate items for a treatment-specific PROM for patients with rheumatic diseases. A future survey will enable the validation of a final version of the PROM.

Efficacy and safety of tofacitinib in patients with rheumatoid arthritis by previous treatment: post hoc analysis of phase II/III trials

BACKGROUND

This study sought to evaluate the efficacy and safety of tofacitinib in patients with rheumatoid arthritis with distinct treatment histories.

METHODS

Pooled phase II/III trial data from patients who received tofacitinib 5 or 10 mg twice daily or placebo, as monotherapy or with conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs), were analyzed post hoc. Separate evaluations were conducted for populations with a prior inadequate response (IR) to: 1) non-methotrexate (MTX) csDMARDs only (non-MTX csDMARD-IR; n = 537); 2) MTX (MTX-IR; n = 3113); and 3) biologic (b)DMARDs (bDMARD-IR; n = 782). Efficacy outcomes included rates of response (American College of Rheumatology 20/50/70% response criteria) and remission (Disease Activity Score in 28 joints derived from 4 measures, erythrocyte sedimentation rate [DAS28-4(ESR)] < 2.6) at month 3, and changes from baseline in DAS28-4(ESR) and Health Assessment Questionnaire-Disability Index scores. Safety was assessed up to month 24.

RESULTS

At month 3, efficacy was generally improved with tofacitinib (both doses) vs placebo in each population. Generally, efficacy outcomes with tofacitinib were numerically more favorable in non-MTX csDMARD-IR vs MTX-IR or bDMARD-IR patients. Over 24 months, crude incidence rates for adverse events (AEs), serious AEs, and discontinuations due to AEs were generally numerically lower in non-MTX csDMARD-IR and MTX-IR vs bDMARD-IR populations; rates for AEs of special interest were generally similar across populations.

CONCLUSIONS

Tofacitinib provided clinical benefit across patients with rheumatoid arthritis with a range of prior treatment experience but may have greater efficacy and an improved benefit/risk profile in those with fewer prior treatments.

Common co-morbidities in polymyalgia rheumatica and giant cell arteritis: cross-sectional study in UK Biobank

Objective

The aim was to determine prevalent co-morbidities in cases with PMR or GCA compared with matched controls.

Methods

This was a nested, cross-sectional case-control study within the UK Biobank, which recruited participants aged 40-69 years. Case status was defined as self-reported prior diagnosis of PMR or GCA. Ten controls per case were matched for age, sex, ethnicity and assessment centre. Associations with selected self-reported co-morbidities were studied using conditional logistic regression.

Results

Of PMR (n = 1036) or GCA (n = 102) cases, 72% were female, 98% White, and 58% reported current use of glucocorticoids. Mean age was 63 years. At the time of the assessment visit, compared with controls, PMR/GCA cases were more likely to report poor general health and at least several days of low mood in the past 2 weeks. PMR was associated with hypothyroidism [odds ratio (OR) = 1.34; 95% CI = 1.07, 1.67] and ever-use of HRT (OR = 1.26; 95% CI = 1.07, 1.47). Regarding common co-morbidities, PMR and GCA were both associated with hypertension (PMR: OR = 1.21; 95% CI = 1.06, 1.39; GCA: OR = 1.86; 95% CI = 1.23, 2.81) and cataract (PMR: OR = 1.51; 95% CI = 1.19, 1.93; GCA: OR = 3.84; 95% CI = 2.23, 6.60). Additionally, GCA was associated with depression (OR = 3.05; 95% CI = 1.59, 5.85). Neither condition was associated with diabetes.

Conclusion

Participants with a history of PMR/GCA, including those not currently taking glucocorticoids, rated their health as poorer than matched controls. Some previously described disease associations (hypothyroidism and early menopause) were replicated. Hypertension and cataract, both of which can be exacerbated by long-term glucocorticoid therapy, were over-represented in both diseases, particularly GCA.

Polymyalgia rheumatica

Polymyalgia rheumatica is an inflammatory disease producing pain and stiffness, mainly in the shoulders and pelvic girdle, in people older than 50 years. Elevation of acute phase reactants is common due to the inflammatory nature of the disease. Since there are no specific diagnostic tests, diagnosis requires the exclusion of other diseases with similar presentations. Imaging has helped to identify the pathological substrate of polymyalgia rheumatica and it is increasingly used to support clinical diagnosis or to detect coexistent giant cell arteritis. Although polymyalgia rheumatica does not clearly impair survival or organ function, it can have a detrimental effect on quality of life. Glucocorticoids at 12·5-25·0 mg prednisone per day are effective in inducing remission in most individuals but, when tapered, relapses occur in 40-60% of those affected and side-effects are common. Assessment of disease activity can be difficult because pain related to common comorbidities such as osteoarthritis and tendinopathies, can return when glucocorticoids are reduced, and acute phase reactants are increased less during flares in individuals undergoing treatment or might increase for other reasons. The role of imaging in assessing disease activity is not yet completely defined. In the search for more efficient and safer therapies, tocilizumab and sarilumab have shown efficacy in randomised controlled trials and additional targeted therapies are emerging. However, judicious risk-benefit balance is essential in applying therapeutic innovations to people with polymyalgia rheumatica.

Tapering and discontinuation of glucocorticoids in patients with rheumatoid arthritis treated with tofacitinib

Although the rapid onset of effect of glucocorticoids (GCs) allows rapid control of rheumatoid arthritis (RA) symptoms, their chronic use may be associated with several adverse events. The 2022 update of EUALR recommendations for the management of patients with RA suggests to reduce and discontinue oral GCs as quickly as possible. Considering GCs as a "bridging therapy" to promptly reduce symptoms and control inflammation, fast-acting drugs such as tofacitinib could allow faster and safer tapering of GCs. The purpose of this pilot study was to evaluate the steroid-sparing effect of adding tofacitinib in patients with RA inadequately responsive to methotrexate taking concomitant GCs. In this open-label pilot study, we enrolled patients with moderate to severe RA on a stable dose of prednisone (5-12.5 mg/day) who started treatment with tofacitinib. After 1 month, in patients who achieved at least a moderate EULAR response (decrease of > 1.2 in DAS28_CRP), GCs was tapered according to a predetermined schedule until complete discontinuation at week 12. Disease activity was assessed after 4, 12, 24 and 48 weeks of treatment. The primary endpoint was the percentage of patients discontinuing GCs after 12 weeks of tofacitinib treatment. We enrolled 30 patients (26 F: 4 M, mean age 60 ± 13 years, mean disease duration 13.2 ± 7.8 years). The primary endpoint was achieved: 9 patients (30%) discontinued GCs at week-12. At week-24, other 12 patients (46%) withdrew GCs. The median prednisone dose decreased from 5 mg/day (interquartile range 5-10 mg) to 2.5 (0-5) mg/day at week 12 and 48 (p < 0.00001 vs baseline). At week 48, 12 out of 30 patients (40%) had discontinued prednisone. The percentage of patients achieving remission or low disease activity increased throughout the follow-up without any difference between patients who discontinued or not the GC. In this cohort of long-standing RA patients treated with tofacitinib, the discontinuation of glucocorticoids was achievable in up to 30% of patients. These results should encourage rheumatologists to consider GCs tapering and discontinuation of GCs, as suggested by the 2022 EULAR recommendations, an achievable goal.

[Pharmacological and clinical profiles of avacopan (TAVNEOS® capsule), a selective C5a receptor antagonist]

Avacopan (TAVNEOS® capsules) is an orally available selective C5a receptor (C5aR) antagonist. It has been approved in Japan since 2021 for the treatment of microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA), the two major subtypes of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). The current standard therapy combining glucocorticoids (GC) and immunosuppressants has greatly improved the prognosis of AAV, however, issues such as side effects associated with GC use remain to be resolved. Avacopan suppresses priming of neutrophils induced by the complement component C5a, a process deeply involved in the pathogenesis of AAV. In pre-clinical studies, avacopan inhibited chemotaxis and priming of neutrophils induced by C5a-C5aR signaling. It also significantly suppressed nephritis and renal damage in an ANCA-induced glomerulonephritis mouse model. In the global phase 3 study "ADVOCATE", avacopan achieved both primary endpoints being 1) non-inferior to prednisone in inducing remission at week 26 and 2) superior in sustained remission at week 52 for MPA and GPA patients. Additionally, with avacopan, GC toxicity score was significantly lower and fewer adverse events possibly related to GC were observed. Furthermore, avacopan increased estimated glomerular filtration rate (eGFR) more than prednisone indicating improved renal function. Thus, the novel mechanism of avacopan targeting the complement system is a promising new therapeutic option for AAV with fewer GC-related side effects and better improvement of renal function.

Steroid-sparing agents in polymyalgia rheumatica: how will they fit into the treatment paradigm?

INTRODUCTION

Polymyalgia rheumatica is a common inflammatory rheumatic disease in subjects aged 50 years or older and classically presents with shoulder and/or pelvic girdle pain and prolonged morning stiffness. Glucocorticoids represent the standard of treatment; glucocorticoid therapy is usually required for 1-2 years and often results in significant glucocorticoid-related side effects, especially in the elderly.

AREAS COVERED

In this review, we aimed to provide a comprehensive overview of the management of polymyalgia rheumatica, with a particular focus on adjunctive therapies to the standard glucocorticoid treatment.

EXPERT OPINION

Given the high frequency of disease relapses (one-third of patients) and the adverse events related to prolonged glucocorticoid use, the need for glucocorticoid-sparing agents remains an important issue in the management of polymyalgia rheumatica. In selected patients, who are at risk for glucocorticoid-related side effects or in those with glucocorticoid-refractory disease, the addition of a glucocorticoid-sparing agent, either a synthetic or biologic disease-modifying anti-rheumatic drug, may represent a reasonable and effective therapeutic approach.

Nanomedicine is more than a supporting role in rheumatoid arthritis therapy

Rheumatoid arthritis(RA) is an autoimmune disorder that affects the joints. Various medications successfully alleviate the symptoms of RA in clinical. Still, few therapy strategies can cure RA, especially when joint destruction begins, and there is currently no effective bone-protective treatment to reverse the articular damage. Furthermore, the RA medications now used in clinical practice accompany various adverse side effects. Nanotechnology can improve the pharmacokinetics of traditional anti-RA drugs and therapeutic precision through targeting modification. Although the clinical application of nanomedicines for RA is in its infancy, preclinical research is rising. Current anti-RA nano-drug studies mainly focus on the following: drug delivery systems, nanomedicines with anti-inflammatory and anti-arthritic properties, biomimetic design with better biocompatibility and therapeutic features, and nanoparticle-dominated energy conversion therapies. These therapies have shown promising therapeutic benefits in animal models, indicating that nanomedicines are a potential solution to the current bottleneck in RA treatment. This review will summarize the present state of anti-RA nano-drug research.

Development of an algorithm for IgG4-related disease management

OBJECTIVES

IgG4-related disease (IgG4-RD) is a rare fibro-inflammatory condition affecting multiple organs lacking standardized management. In this article, we review the evidence available to provide European expert-based statements on the management of IgG4-RD which were integrated in a final algorithm.

METHODS

A panel of nine European experts in IgG4-RD from different specialties was asked to elaborate a set of consensus statements through a Delphi exercise. Three rounds of survey were taken. Consensus was reached when ≥75% of the responders agreed with a statement.

RESULTS

Thirty-one statements on induction treatment, maintenance treatment, non-pharmacological treatment, and general considerations were assessed. Patients should be treated promptly in situations when there is an immediate organ threatened, or when organ damage is anticipated. Glucocorticoids (GC) are considered the first line of treatment and should be progressively tapered. Maintenance treatment is recommended for patients with high disease activity or with risk factors for relapse. Rituximab is effective for induction and maintenance of remission, but its use can be limited by economics. Low dose GC with or without GC-sparing agents can be used for maintenance therapy. Stenting or surgery should be ancillary to pharmacological treatment. Follow up should be based on physical examination, blood works, and imaging studies. Furthermore, it should be tailored on individual patient clinical history. 18-fluorodeoxyglucose positron emission tomography/computerized tomography may provide additional information over other imaging modalities.

CONCLUSIONS

These new statements and algorithm reached a high degree of agreement and may help guiding the clinical management of IgG4-RD.

Glucocorticoid Toxicity Index scores by domain in patients with antineutrophil cytoplasmic antibody-associated vasculitis treated with avacopan versus standard prednisone taper: post-hoc analysis of data from the ADVOCATE trial

BACKGROUND

The ADVOCATE trial, in which the complement C5a receptor inhibitor avacopan was compared with a standard prednisone taper in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, used the Glucocorticoid Toxicity Index (GTI) to measure glucocorticoid toxicity change. We set out to do a post-hoc analysis of the ADVOCATE data to evaluate changes in individual GTI domains and their ability to differentiate treatment groups.

METHODS

The ADVOCATE trial was a phase 3, double-blind, double-dummy, randomised trial comparing oral avacopan (30 mg) twice daily for 52 weeks plus a prednisone-matching placebo for 20 weeks with oral prednisone tapered over 20 weeks plus an avacopan-matching placebo for 52 weeks in patients with ANCA-associated vasculitis. GTI data were collected within each of the included domains (BMI, blood pressure, glucose tolerance, lipid metabolism, glucocorticoid myopathy, skin toxicity, neuropsychiatric effects, and infections) at baseline, 13 weeks, and 26 weeks. In this post-hoc analysis, we calculated the cumulative worsening score (CWS) and aggregate improvement score (AIS) for each GTI domain, assessed to what extend each domain contributed to the GTI score, and which domains differentiated between the avacopan and prednisone groups. Differences in domain scores between the two groups were compared using Mantel-Haenszel χ2 tests.

FINDINGS

Among the 330 patients included in the intention-to-treat population of the ADVOCATE trial, 321 (97%) had complete data at week 13 (160 in the avacopan group, and 161 in the prednisone group), and 307 (93%) had complete data at week 26 (154 in the avacopan group, and 153 in the prednisone group) and were assessed in this post-hoc study. In ADVOCATE, mean age in both groups was 61 years (61·2 years [SD 14·6] in the avacopan group; 60·5 years [14·5] in the prednisone group); 98 (59%) of 166 patients in the avacopan group were men and 68 (41%) were women; 88 (54%) of 164 patients in the prednisone group were men and 76 (46%) were women. 278 (84%) of 330 patients were White. The mean glucocorticoid use over 26 weeks was lower in the avacopan group than the prednisone group (1073 mg [SD 1669] vs 3192 mg [1174]). Significantly less glucocorticoid toxicity was observed in the avacopan group than the prednisone group by week 13 in four domains of the GTI (BMI, glucose tolerance, lipid metabolism, and skin toxicity), based on both the CWS and AIS. CWS values in the BMI, lipid metabolism, and skin toxicity domains were significantly lower in the avacopan group than the prednisone group at 26 weeks. No domain favoured the prednisone group for glucocorticoid toxicity reduction. 280 (91%) of 307 patients had glucocorticoid toxicity at 26 weeks. Blood pressure (35% in the avacopan group vs 25% in the prednisone group), infection (22% vs 24%), and lipid metabolism (20% vs 15%) contributed the most weight toward CWS values at 26 weeks. 128 (42%) of 307 patients had combinations of improvement and worsening in different domains at 26 weeks.

INTERPRETATION

Replacing a standard prednisone taper with avacopan in patients with ANCA-associated vasculitis reduced glucocorticoid toxicity in multiple GTI domains. For individual patients, glucocorticoid toxicity was often nuanced, improving in some domains while worsening in others. These findings emphasise the value of a composite measure of glucocorticoid toxicity that quantifies cumulative worsening and aggregate change directly.

Therapeutic Response After Immunosuppressive Drug Prescription in Non-infectious Uveitis: A Survival Analysis

INTRODUCTION

To identify factors affecting the response rate to immunosuppressive drugs (ISDs) in patients with non-infectious uveitis (NIU).

METHODS

This longitudinal retrospective cohort study included patients from the Hospital Clinico San Carlos Uveitis Clinic diagnosed with NIU from 1992 to 2016. Subjects were followed up from ISD prescription until the achievement of good therapeutic response (GTR), ISD treatment change, or up to 12 months. GTR was defined as the complete resolution of the eye inflammatory manifestations with a corticosteroid dose ≤ 10 or ≤ 5 mg per day of prednisone or equivalent (GTR10 and GTR5, respectively) maintained for at least 28 days. Kaplan-Meier curves were estimated for GTR. Demographic, clinical, and treatment-related factors were analyzed using Cox robust regression.

RESULTS

A total of 73 patients (100 episodes of ISD prescription) were analyzed. In 44 and 41 episodes, GTR10 and GTR5 were achieved, respectively. A lower hazard for both GTRs was associated with uveitic macular edema at prescription and with a higher "highest oral corticosteroid dose prescribed in the year before ISD prescription". GTR10 was higher if cyclosporine was prescribed (compared to other ISDs), and if a higher number of ISDs had been previously prescribed. GTR5 hazard was lower for patients with posterior uveitis or if the ISDs were prescribed before 2008, and higher if periocular corticosteroids had been administered before ISD prescription, or if the duration of the posterior segment activity was shorter.

CONCLUSIONS

Factors associated with GTR to ISDs may help to identify patients with NIUs who could benefit from a thorough follow-up.

Clinical characteristics and related influencing factors of common rheumatic diseases concomitant with tuberculosis

Objective

To explore the clinical characteristics and risk factors of common systemic rheumatism concomitant with tuberculosis (TB).

Methods

A total of 3,906 patients of RA, SLE, and SS diagnosed in the People's Hospital of Sichuan Province from January 2007 to January 2017 were collected. One hundred and five patients with TB were included as TB group, including 42 RA, 41 SLE, and 22 SS patients. In the non-TB group, 84 RA, 82 SLE, and 44 SS patients were randomly selected during the same period.

Results

Fever was the most common symptom among RA, SLE, and SS patients with TB, accounting for 83.3%, 92.7%, and 68.2%, respectively. Cough, weight loss or fatigue were the next common. RA patients with TB were mostly pulmonary TB (PTB), accounting for 64.3%. The proportion of PTB for SLE and SS were 46.3%, 59.01%, respectively. In TB group, 59% RA, 57% SLE, and 62% SS with PTB had two or more chest CT findings. There were 48 TB cases received both Interferon Gamma Release Assay (IGRA) and Tuberculin skin test (TST) with positive rates of 91.8%, 45.8%, respectively. The daily average dose of glucocorticoids within 1 year in TB group was higher than that in non-TB group of SLE patients, lower counts of CD4+ T cell count were found in TB group (P < 0.05), while no such differences were found in RA and SS patients.

Conclusion

RA patients with TB are mainly pulmonary TB. For SLE and SS patients, the chance of PTB and extrapulmonary tuberculosis is similar. Daily average dose of glucocorticoids within 1 year may be a common risk factor for RA, SLE and SS patients developing TB. Decreased CD4+ T cell count may also be a risk factor for SLE patients with TB. Symptoms of RA, SLE, SS with TB, are similar with the primary disease or other infection.

Efficacy, duration of use and safety of glucocorticoids: a systematic literature review informing the 2022 update of the EULAR recommendations for the management of rheumatoid arthritis

This systematic literature review (SLR) regarding the efficacy, duration of use and safety of glucocorticoids (GCs), was performed to inform the 2022 update of the EULAR recommendations for the management of rheumatoid arthritis (RA). Studies on GC efficacy were identified from a separate search on the efficacy of disease-modifying antirheumatic drugs (DMARDs). A combined search was performed for the duration of use and safety of GCs in RA patients. Dose-defined and time-defined GC treatment of any dose and duration (excluding intra-articular GCs) prescribed in combination with other DMARDs were considered. Results are presented descriptively. Two included studies confirmed the efficacy of GC bridging as initial therapy, with equal efficacy after 2 years of initial doses of 30 mg/day compared with 60 mg/day prednisone. Based on a recently performed SLR, in clinical trials most patients starting initial GC bridging are able to stop GCs within 12 (22% patients continued on GCs) to 24 months (10% patients continued on GCs). The safety search included 12 RCTs and 21 observational studies. Well-known safety risks of GC use were confirmed, including an increased risk of osteoporotic fractures, serious infections, diabetes and mortality. Data on cardiovascular outcomes were Inconsistent. Overall, safety risks increased with increasing dose and/or duration, but evidence on which dose is safe was conflicting. In conclusion, this SLR has confirmed the efficacy of GCs in the treatment of RA. In clinical trials, most patients have shown to be able to stop GCs within 12-24 months. Well-known safety risks of GC use have been confirmed, but with heterogeneity between studies.

Incidence and Risk Factors of Hyperglycemia in Severe Multisystem Inflammatory Syndrome in Children: A Retrospective Case-Control Study

Objective Multisystem inflammatory syndrome in children (MIS-C) patients might be at risk for hyperglycemia and associated complications. Herein, we aimed to determine the incidence of hyperglycemia, understanding the underlying risk factors in MIS-C patients.

Methods All MIS-C patients were retrospectively evaluated and compared according to the presence of hyperglycemia and the need of insulin. Inflammatory markers and body mass index Z-scores were also compared.

Results The median age of the patients with hyperglycemia was higher than those without (p = 0.001). Disease severity scores of patients with hyperglycemia were higher. Procalcitonin levels of patients with hyperglycemia were higher, while ferritin, CRP, and interleukin-6 levels were not. BMIs of patients with hyperglycemia were higher (p = 0.01) but BMI Z-scores were similar (p = 0.055). There was a positive correlation between BMIs and CRP (r: 0.31, p = 0.015). There was a positive correlation between procalcitonin (r: 0.431, p = 0.001) and CRP (r: 0.279, p = 0.029) and maximum PG.

Conclusion Hyperglycemia is a common feature of MIS-C patients and is associated with the severity of the inflammation. As a novel finding, high CRP and procalcitonin should be considered as predictive markers for impaired glucose homeostasis in MIS-C patients.

EULAR recommendations for the management and vaccination of people with rheumatic and musculoskeletal diseases in the context of SARS-CoV-2: the November 2021 update

The first EULAR provisional recommendations on the management of rheumatic and musculoskeletal diseases (RMDs) in the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), largely based on expert opinion, were published in June 2020. Since then, an unprecedented number of clinical studies have accrued in the literature. Several SARS-CoV-2 vaccines have been approved for population-wide vaccination programmes in EULAR-affiliated countries. Studies regarding vaccination of patients with (inflammatory) RMDs have released their first results or are underway.EULAR found it opportune to carefully review to what extent the initially consensus expert recommendations stood the test of time, by challenging them with the recently accumulated body of scientific evidence, and by incorporating evidence-based advice on SARS-CoV-2 vaccination. EULAR started a formal (first) update in January 2021, performed a systematic literature review according to EULAR's standard operating procedures and completed a set of updated overarching principles and recommendations in July 2021. Two points to consider were added in November 2021, because of recent developments pertaining to additional vaccination doses.

Accrual of organ damage in Behçet's syndrome: trajectory, associated factors, and impact on patients' quality of life over a 2-year prospective follow-up study

BACKGROUND

This study aimed to investigate the trajectory of damage accrual, associated factors, and impact on health-related quality of life (HR-QoL) in a multicenter cohort of patients with Behçet's syndrome (BS) over 2 years of follow-up.

METHODS

Patients recruited in the BS Overall Damage Index (BODI) validation study were prospectively monitored for 2 years and assessed for damage accrual, defined as an increase ≥1 in the BODI score, and HR-QoL was evaluated by the SF-36 questionnaire. Logistic and multiple linear regression models were built to determine factors associated with damage accrual and impairment in the different SF-36 domains.

RESULTS

During follow-up, 36 out of 189 (19.0%) patients had an increase ≥1 in the BODI score with a mean (SD) difference of 1.7 (0.8) (p <0.001). The incidence rate of damage accrual was stable over time, regardless of the disease duration. Out of 61 new BODI items, 25 (41.0%) were considered related to glucocorticoid (GC) use. In multivariate analysis, duration of GC therapy (OR per 1-year 1.15, 95% CI 1.07-1.23; p <0.001) and occurrence of ≥1 disease relapse (OR 3.15, 95% CI 1.09-9.12; p 0.038) were identified as predictors of damage accrual, whereas the use of immunosuppressants showed a protective effect (OR 0.20, 95% CI 0.08-0.54, p<0.001). Damage accrual was independently associated with the impairment of different physical domains and, to a greater extent, in emotional domains of the SF-36 questionnaire. Female sex, higher disease activity, and fibromyalgia were also significantly associated with impairment in HR-QoL.

CONCLUSION

In BS, organ damage accrues over time, also in long-standing disease, resulting in an impairment of the perceived physical and mental health. Adequate immunosuppressive treatment, preventing disease flares and minimizing exposure to GCs have a crucial role in lowering the risk of damage accrual.

Evidence based Latin American Guidelines of clinical practice on prevention, diagnosis, management and treatment of glucocorticoid induced osteoporosis. A 2022 update : This manuscript has been produced under the auspices of the Committee of National Societies (CNS) and the Committee of Scientific Advisors (CSA) of the International Osteoporosis Foundation (IOF)

Guidelines and recommendations developed and endorsed by the International Osteoporosis Foundation (IOF) are intended to provide guidance for particular pattern of practice for physicians who usually prescribe glucocorticoid (GC) therapy, and not to dictate the care of a particular patient. Adherence to the recommendations within this guideline is voluntary and the ultimate determination regarding their application should be made by the physician in light of each patient's circumstances. Guidelines and recommendations are intended to promote a desirable outcome but cannot guarantee any specific outcome. This guideline and its recommendations are not intended to dictate payment, reimbursement or insurance decisions. Guidelines and recommendations are subjected to periodic revisions as a consequence of the evolution of medicine, technology and clinical practice. A panel of Latin American (LATAM) experts specialized in osteoporosis with recognized clinical experience in managing patients with glucocorticoid-induced osteoporosis (GIO) met to produce evidence-based LATAM recommendations for the diagnosis and management of GIO. These guidelines are particularly intended to general practitioners and primary care physicians who prescribe GC treatments in LATAM to guide their daily clinical practice in terms of evaluation, prevention and treatment of GIO. These recommendations were based on systematic literature review using MEDLINE, EMBASE, SCOPUS and COCHRANE Library database during the period from 2012 to 2021. Randomized clinical trials (RCT), systematic reviews of RCT, controlled observational studies, guidelines and consensus were considered. Based on the review and expert opinion the panel members voted recommendations during two successive rounds of voting by panel members. Agreements for each statement were considered if a concordance of at least 70% was achieved following Delphi methodology. Grading of recommendations was made according to the Oxford Centre for the Evidence-based Medicine (EBM) criteria. Among five GIO guidelines and consensus initially identified, two of them (American College of Rheumatology 2017 and the Brazilian Guidelines 2021) were selected for comparison considering the latter as the most current guides in the LATAM region. Based on this methodology fifty statements were issued. All of them but four (1.20, 1.21, 1.23 and 4.2) attained agreement.

[Development of quality standards for patients with rheumatoid arthritis for use in Germany]

Despite a qualitatively and structurally good care of patients with rheumatoid arthritis (RA) in Germany, there are still potentially amendable deficits in the quality of care. For this reason, the German Society for Rheumatology (DGRh) has therefore decided to ask a group of experts including various stakeholders to develop quality standards (QS) for the care of patients with RA in order to improve the quality of care. The QS are used to determine and quantitatively measure the quality of care, subject to relevance and feasibility. The recently published NICE and ASAS standards and a systematic literature search were used as the basis for development. A total of 8 QS, now published for the first time, were approved with the intention to measure and further optimize the quality of care for patients with RA in Germany.

A Critical Look at Race-Based Practices in Rheumatology Guidelines

OBJECTIVE

To assess how race has been incorporated into rheumatology practice guidelines, including how race is defined and used in diagnostic and treatment recommendations.

METHODS

We searched race and ethnicity terms in all clinical practice guidelines from the American College of Rheumatology (ACR) and European Alliance of Associations for Rheumatology (EULAR) that were published between 2010 and 2020 and publicly available on professional society websites. Findings were summarized and assessed through standardized data abstraction forms. Key themes were identified through a thematic analysis approach.

RESULTS

A total of 23 ACR clinical practice guidelines and 42 EULAR recommendations were reviewed. In total, 16 of 65 (25%) of the guidelines used race terms in their text. No guideline clearly defined race, and race was often conflated with ethnicity and/or genetic ancestry. Reported racial categories varied substantially by guideline and often used classifications that oversimplified and excluded non-White races. Research with insufficient racial diversity was used to make race-based recommendations for Black patients that may not be generalizable. Additionally, recommendations using research on predominantly White populations reinforced data of White populations as normative and perpetuated race-based stereotypes, especially for rare diseases. Structural causes of identified racial disparities were not discussed in clinical guidelines.

CONCLUSION

There is an urgent need for standardized race reporting in rheumatology. Recommendations are provided to enhance consistency and accuracy of race and ethnicity terms, mitigate conflation of race with ethnicity or genetic ancestry, encourage a critical reanalysis of race-based diagnostic tools and treatment options, and better address the structural causes of racial disparities.

Inadequate Dietary Nutrient Intake in Patients With Rheumatoid Arthritis in Southwestern Sweden: A Cross-Sectional Study

Background

Patients with rheumatoid arthritis (RA), who suffer from impaired physical function and fatigue, may have difficulties with grocery shopping and preparing meals. Also, to improve symptoms, patients often experiment with diets but seldom consult a dietitian. Although this could lead to a nutritiously deprived diet, an up-to-date, thorough description of the nutrient intake in Swedish patients with RA is absent. Here, we investigated the habitual dietary energy and nutrient intake in patients with RA living in southwestern Sweden.

Materials and Methods

Three-day food records performed at two time points during the ADIRA (Anti-inflammatory Diet In Rheumatoid Arthritis) trial, were used. The intake of energy and nutrients was analyzed using The Swedish Food Composition Database.

Results

A total of 62 participants (50 females, 12 males) were included in the study, where 18 participants completed one 3-day food record and 44 participants completed two 3-day food records. Median (IQR) intake of total fat was above or in the upper range of recommendations (females: 37.1 [32.5, 41.7] energy percent (E%), and males: 40.3 [37.5, 42.9] E%). Median (IQR) intake of saturated fatty acids exceeded recommendations (females: 14.9 [12.5, 17.0] E% and males: 15.4 [12.2, 17.0] E%), while median (IQR) carbohydrate and fiber intakes were below recommendations (females: 41.7 [36.3, 45.4] E% and 17.2 [12.8, 20.9] g, respectively, and males: 38.8 [35.2, 40,3] E% and 18.5 [15.7, 21.0] g, respectively). The reported intake of other macronutrients was in line with recommendations. For several micronutrients, e.g., vitamin A and D, folate, and calcium, median intake was below recommended intake. Vitamin A intake was especially low and did not reach lower intake level (LI) for 14 and 17% of females and males, respectively. For females, about 10% did not reach LI for vitamin D, calcium, and riboflavin.

Conclusion

We found that patients with RA residing in southwestern Sweden reported a high intake of saturated fatty acids and low intake of fiber and several micronutrients.

Systemic Treatment of Advanced Unresectable Hepatocellular Carcinoma after First-Line Therapy: Expert Recommendations from Hong Kong, Singapore, and Taiwan

BACKGROUND

Asia has a high burden of hepatocellular carcinoma (HCC) due to the high rates of chronic hepatitis B infection and accounts for 70% of HCC cases globally. In the past 20 years, the systemic treatment landscape of advanced HCC has evolved substantially - from tyrosine kinase inhibitors to immune-oncology agents plus anti-vascular endothelial growth factor agents. The appropriate sequence of therapies has become critical in optimizing patient outcomes given the increase in systemic therapeutic options. This article evaluates the evidence and provides expert recommendations for the use of systemic therapies after first-line treatment in patients with advanced HCC.

SUMMARY

Based on three virtual meetings held in early 2021, a team of 17 experts comprising oncologists, a hepatologist, and a hepatobiliary surgeon from Hong Kong, Singapore, and Taiwan reviewed available data about systemic treatments for HCC after first line and formulated 28 statements. These statements aimed to provide expert guidance on selecting first and subsequent lines of therapies as well as recommending therapies in special circumstances, such as poor liver function, posttransplantation, recent gastrointestinal bleeding, or autoimmune diseases. Data supporting the statements were drawn from clinical trials and real-world studies. The 28 statements were then evaluated anonymously using a 5-point Likert scale, and 24 reached consensus, predefined as achieving 75% agreement. Statements generated covered the selection of first-line systemic therapy, considerations and goals of second-line systemic therapies, treatment selection following first-line therapy, and treatment recommendations following first-line tyrosine kinase inhibitors, immune-oncology monotherapy, or immune-oncology combination therapy. The authors also shared expert opinion on the use of second-line systemic therapy in patients with liver dysfunction, liver transplantation, and recent gastrointestinal or autoimmune disease.

KEY MESSAGES

These expert statements summarize the latest data and expert opinion on selecting systemic treatment following first-line therapy in patients with unresectable advanced or metastatic HCC.

Prevention and Treatment of Glucocorticoid-Induced Osteoporosis in Adults: Consensus Recommendations From the Belgian Bone Club

Glucocorticoids are effective immunomodulatory drugs used for many inflammatory disorders as well as in transplant recipients. However, both iatrogenic and endogenous glucocorticoid excess are also associated with several side effects including an increased risk of osteoporosis and fractures. Glucocorticoid-induced osteoporosis (GIOP) is a common secondary cause of osteoporosis in adults. Despite availability of clear evidence and international guidelines for the prevention of GIOP, a large treatment gap remains. In this narrative review, the Belgian Bone Club (BBC) updates its 2006 consensus recommendations for the prevention and treatment of GIOP in adults. The pathophysiology of GIOP is multifactorial. The BBC strongly advises non-pharmacological measures including physical exercise, smoking cessation and avoidance of alcohol abuse in all adults at risk for osteoporosis. Glucocorticoids are associated with impaired intestinal calcium absorption; the BBC therefore strongly recommend sufficient calcium intake and avoidance of vitamin D deficiency. We recommend assessment of fracture risk, taking age, sex, menopausal status, prior fractures, glucocorticoid dose, other clinical risk factors and bone mineral density into account. Placebo-controlled randomized controlled trials have demonstrated the efficacy of alendronate, risedronate, zoledronate, denosumab and teriparatide in GIOP. We suggest monitoring by dual-energy X-ray absorptiometry (DXA) and vertebral fracture identification one year after glucocorticoid initiation. The trabecular bone score might be considered during DXA monitoring. Extended femur scans might be considered at the time of DXA imaging in glucocorticoid users on long-term (≥ 3 years) antiresorptive therapy. Bone turnover markers may be considered for monitoring treatment with anti-resorptive or osteoanabolic drugs in GIOP. Although the pathophysiology of solid organ and hematopoietic stem cell transplantation-induced osteoporosis extends beyond GIOP alone, the BBC recommends similar evaluation, prevention, treatment and follow-up principles in these patients. Efforts to close the treatment gap in GIOP and implement available effective fracture prevention strategies into clinical practice in primary, secondary and tertiary care are urgently needed.

Cardiovascular Involvement in Sjögren’s Syndrome

Sjögren Syndrome (SS) seems to be associated with a greater “overall risk” of cardiovascular (CV) and cerebrovascular events. Although not conventionally considered a feature of the disease, CV events represent a major burden in SS patients. CV risk is the consequence of a complex combination of multiple factors, including traditional risk factors and disease-related mechanisms. A complex relationships between disease-related features, endothelial dysfunction and traditional risk factor has been suggested. Several drugs are available for treating the systemic manifestations of SS, however they have shown positive effects on different outcomes of the disease, but until today the data on the role of these drugs on CV events are scarse. Given these data, the aim of this review was to evaluate the risk of CV risk in primary SS and the effect of the drugs on this manifestation.
