Combination of clinical factors predicts successful glucocorticoid withdrawal in systemic lupus erythematosus (SLE): results from a multicentre, retrospective cohort study.

Objective: Glucocorticoid (GC) tapering and withdrawal to reduce damage represents a key aspect of the European Alliance of Associations for Rheumatology (EULAR) SLE recommendations. However, optimal strategies for relapse-free GC cessation remain ill-defined. We characterised clinical predictors and their combined effect on flares in patients with SLE who discontinued GC.

Neuropsychiatric prodromes and symptom timings in relation to disease onset and/or flares in SLE: results from the mixed methods international INSPIRE study.

Background: Neuropsychiatric symptoms in SLE and other systemic autoimmune rheumatic diseases (SARDs) are challenging to diagnose, attribute and manage. We investigated the timings of onset of a broad range of neuropsychiatric (NP) symptoms in relation to timing of SLE onset. In addition, we explored whether NP symptoms may be a prodrome to SARD onset and to subsequent flares.

Risk of developing psoriatic arthritis in psoriasis cohorts with arthralgia: exploring the subclinical psoriatic arthritis stage.

Objective: Subjects with subclinical psoriatic arthritis (PsA), defined as the presence of arthralgia in psoriasis (PsO), are at higher risk of PsA but scant real-world data exist. Our aims were to (1) estimate the probability of PsA development in subclinical PsA, (2) characterise subclinical PsA symptoms and (3) determine the clinical patterns at PsA diagnosis.

Methods: Patients with PsO, mainly subclinical PsA, were evaluated longitudinally in two European cohorts.

Neuropsychiatric symptoms in Systemic Lupus Erythematosus: mixed methods analysis of patient-derived attributional evidence in the international INSPIRE project.

Objective: Attribution of neuropsychiatric symptoms in systemic lupus erythematosus (SLE) relies heavily on clinician assessment. Limited clinic time, variable knowledge, and symptom under-reporting contributes to discordance between clinician assessments and patient symptoms. We obtained attributional data directly from patients and clinicians in order to estimate and compare potential levels of direct attribution to SLE of multiple neuropsychiatric symptoms using different patient-derived measures.

High-grade synovitis associates with clinical markers and response to therapy in chronic inflammatory arthritis: analysis of a synovial biomarkers prospective cohort study.

Background: Inflammatory arthritis (IAs), such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA), are characterized by the presence of chronic synovitis. The Krenn's synovitis score (KSS), a simple tool detectable by haematoxylin/eosin staining of synovial biopsy samples, allows the discrimination between high-grade and low-grade synovitis. The aim of this study was to identify the clinical associations of KSS and to evaluate the relationship between high-grade synovitis and treatment response in IA patients.

Pragmatic targets for moderate/severe SLE and their implications for clinical care and trial design: sustained DORIS or LLDAS for at least 6 months is sufficient while their attainment for at least 24 months ensures high specificity for damage-free progression.

Objectives: Treatment targets in systemic lupus erythematosus (SLE) have been validated in unselected-in terms of severity-cohorts, which limits their generalisability. We assessed remission (Definition of Remission in SLE (DORIS)) and Lupus Low Disease Activity State (LLDAS) in a historical cohort of 348 patients with active moderate-to-severe disease and median follow-up of 5 years.

Methods: Active SLE was defined as Physician Global Assessment ≥1.

Tofacitinib restores psoriatic arthritis fibroblast-like synoviocytes function via autophagy and mitochondrial quality control modulation.

Objectives: To evaluate the in vitro effect of tofacitinib on autophagy activity of psoriatic arthritis (PsA) fibroblast-like synoviocytes (FLS), and to confirm its activity on inflammatory and invasive properties of FLS and synovial cells, deepening the impact on mitochondrial function.

Methods: FLS, peripheral blood mononuclear cells (PBMCs), and synovial cells from active PsA patients were cultured with tofacitinib 1 μM or vehicle control for 24 h. Autophagy was measured by Western blot and by fluorescence microscopy.

Studying the Interactions of U24 from HHV-6 in Order to Further Elucidate Its Potential Role in MS.

A number of studies have suggested that human herpesvirus 6A (HHV-6A) may play a role in multiple sclerosis (MS). Three possible hypotheses have been investigated: (1) U24 from HHV-6A (U24-6A) mimics myelin basic protein (MBP) through analogous phosphorylation and interaction with Fyn-SH3; (2) U24-6A affects endocytic recycling by binding human neural precursor cell (NPC) expressed developmentally down-regulated protein 4-like WW3* domain (hNedd4L-WW3*); and (3) MS patients who express Killer Cell Immunoglobulin Like Receptor 2DL2 (KIR2DL2) on natural killer (NK) cells are more susceptible to HHV-6 infection. In this contribution, we examined the validity of these propositions by investigating the interactions of U24 from HHV-6B (U24-6B), a variant less commonly linked to MS, with Fyn-SH3 and hNedd4L-WW3* using heteronuclear single quantum coherence (HSQC) nuclear magnetic resonance (NMR) titrations and isothermal titration calorimetry (ITC).

Predictors of disease activity in gout: a 12-month analysis of the ATTACk (Achieving improvement in the management of crystal-induced arthritis) multicentre cohort study.

Objectives: Gout treatment is largely suboptimal in clinical practice. We aimed to assess the predictors of disease-activity at 12 months in a real-life setting.

Methods: Consecutive patients referred to Rheumatology Units for suspected acute crystal-induced arthritis were enrolled in a multicentre-cohort study.

Novel insights into the management of rheumatoid arthritis: one year in review 2022.

New evidence for the treatment of rheumatoid arthritis (RA) has emerged during the last year. Specifically, updated guidelines on pharmacological and non-pharmacological management of RA have emphasised the necessity of global patient's care, and have shifted the role of some older drugs, such as glucocorticoids and methotrexate. In addition, the long-term safety of Janus kinase inhibitors was investigated and reinforced.

Herpesvirus Infections in KIR2DL2-Positive Multiple Sclerosis Patients: Mechanisms Triggering Autoimmunity.

In multiple sclerosis (MS), there is a possible relationship with viral infection, evidenced by clinical evidence of an implication of infectious events with disease onset and/or relapse. The aim of this research is to study how human herpesvirus (HHVs) infections might dysregulate the innate immune system and impact autoimmune responses in MS. We analyzed 100 MS relapsing remitting patients, in the remission phase, 100 healthy controls and 100 subjects with other inflammatory neurological diseases (OIND) (neuro-lupus) for their immune response to HHV infection.

An Italian Multicenter Study on Anti-NXP2 Antibodies: Clinical and Serological Associations.

The identification of anti-NXP2 antibodies is considered a serological marker of dermatomyositis (DM), with calcinosis, severe myositis and, in some reports, with cancer. Historically, these associations with anti-NXP2 antibodies have been detected by immunoprecipitation (IP), but in the last few years commercial immunoblotting assays have been released. The aim of this collaborative project was to analyse the clinical features associated to anti-NXP2 antibodies, both with commercial line blot (LB) and IP.

Persistence of bDMARD therapy in Rheumatoid Arthritis after first-line TNF-inhibitor failure: the RECORD study of the Italian Society for Rheumatology.

Objective: The optimal choice of a second biological disease-modifying anti-rheumatic drug (bDMARD) after failure with first line tumour necrosis factor inhibitor (TNFi) represents a critical therapeutic challenge. This study aims to evaluate the persistence with treatment using second line bDMARDs with different mechanisms of action in rheumatoid arthritis (RA) patients with inadequate response to first line TNFi.

Method: A retrospective cohort study on administrative healthcare databases was conducted.

Use of Ultrasonography to Discriminate Psoriatic Arthritis from Fibromyalgia: A Post-Hoc Analysis of the ULISSE Study.

In psoriatic arthritis (PsA) patients with concomitant chronic widespread pain, the differential diagnosis with fibromyalgia syndrome (FMS) can be challenging. We evaluated whether ultrasound (US) examination of entheseal sites can distinguish pain from (PsA) enthesitis versus FMS. PsA and FMS patients underwent clinical evaluation and gray-scale (GS; B-mode) and power Doppler (PD) US examination of the entheses.

Rheumatoid Arthritis and Cardiovascular Risk: Retrospective Matched-Cohort Analysis Based on the RECORD Study of the Italian Society for Rheumatology.

Rheumatoid arthritis (RA) is associated with an increase in cardiovascular (CV) risk. This issue maybe not only explained by a genetic component, as well as by the traditional CV risk factors, but also by an underestimation and undertreatment of concomitant CV comorbidities. This was a retrospective matched-cohort analysis in the Italian RA real-world population based on the healthcare-administrative databases to assess the CV risk factors and incidence of CV events in comparison with the general population.

Impact of disease duration and gender on the sensitivity and specificity of 2015 ACR/EULAR classification criteria for gout. Cross-sectional results from an Italian multicentric study on the management of crystal-induced arthritis (ATTACk).

Objectives: We aimed to assess the performance of the 2015 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) gout classification criteria in an Italian cohort of patients with crystal-induced arthritis stratified by disease duration and gender in a real-life setting.

Methods: Consecutive patients referred to Rheumatology Units for suspected acute crystal-induced arthritis were enrolled in a multicentre cohort study by the Italian Society of Rheumatology which was designed to improve the management of crystal-induced arthritis (ATTACk). To test the performance of the criteria (sensitivity and specificity), the presence of monosodium urate (MSU) crystals in synovial fluid (SF) was used as gold standard.

One year in review 2021: novelties in the treatment of rheumatoid arthritis.

Management of rheumatoid arthritis (RA) has evolved over the years as a result of better understanding of the role of different therapeutic strategies, as well as following an increasing availability of new disease-modifying antirheumatic drugs. However, the role of patients in sharing decisions, as well as the rules informing precision medicine or the principles to follow in case of specific comorbidities or extra-articular manifestations are still areas for improvement. Moreover, in 2020, the novel Coronavirus disease-19 outbreak has completely changed many attitudes in terms of assessment and treatment paradigms in most clinical diseases, including RA.

Relevant domains and outcome measurement instruments in neuropsychiatric systemic lupus erythematosus: a systematic literature review.

Objectives: Although neuropsychiatric involvement in SLE (NPSLE) is one of the most complex and troubling manifestations of the disease, validated outcome instruments to be used as sensitive endpoints in controlled clinical trials are lacking. We performed a systematic literature review (SLR) to identify outcome measurement instruments and domains used to assess NPSLE.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used.
