Fibromyalgia syndrome (FMS) is a condition characterized by widespread musculoskeletal pain, often involving a neuropathic component. While pathophysiology remains vague, increasing evidence suggests that small fiber pathology (SFP) may be present in a significant subset of patients, indicating a peripheral nervous system contribution. This systematic review aims to evaluate the utility of skin biopsy as a diagnostic tool for patients with FMS, with special focus on SFP. A comprehensive database search was conducted to identify studies assessing intraepidermal nerve fiber density (IENFD) via skin biopsy in individuals diagnosed with FMS. The included studies demonstrated a reduction in IENFD in a substantial proportion of FMS patients, with reported prevalence ranging widely from 30% to over 85%. Small fiber pathology occurs in a significant proportion of individuals with FMS. Skin biopsy emerges as a valuable diagnostic tool. Further research is needed to better understand the underlying mechanism of SFP in FMS.

To systematically review the spectrum of urological manifestations and fertility outcomes reported in FMF patients, excluding renal amyloidosis-related involvement.

Anti-synthetase syndrome (ASyS) is a rare autoimmune disorder defined by anti-synthetase antibodies. While malignancy is established in DM, its association with ASyS remains unclear. We aimed to estimate malignancy prevalence in ASyS and assess whether autoantibody subtype, age, sex or clinical features influence malignancy risk.

Glucocorticoids (GCs) are the cornerstone of polymyalgia rheumatica (PMR) treatment, but the optimal tapering strategy remains unclear. This systematic review aimed to explore the impact of published GC tapering strategies on remission, flare rates, GC discontinuation, cumulative GC doses and patient-reported outcomes (PROs).

Peripheral manifestations (peripheral arthritis/enthesitis/dactylitis) are frequent in axial spondyloarthritis (axSpA) yet, understudied. We (i) evaluated the assessment/reporting of peripheral manifestations in trials of biological or targeted synthetic DMARDs (b/tsDMARDs) for axSpA and peripheral SpA (pSpA), and (ii) synthesized the efficacy of b/tsDMARDs on these manifestations.

Hyperuricaemia is not currently included in major global health surveillance frameworks, including the Global Burden of Diseases, Injuries, and Risk Factors Study, despite its well established clinical associations with non-communicable diseases. The absence of harmonised, comparable sex-specific prevalence estimates of hyperuricaemia across countries has limited its visibility in public health planning and prevention strategies. We aimed to provide the first standardised, sex-specific, global, regional, and national estimates of hyperuricaemia prevalence and cases from 2000 to 2023.

Despite growing evidence supporting the benefits of physical activity in patients with rheumatic and musculoskeletal diseases (RMDs), both clinicians and patients often remain cautious-particularly regarding higher intensities. Although exercise is universally recommended in international guidelines for these populations, it is frequently accompanied by warnings to engage only in moderate-intensity training. The primary objective of this systematic review was to examine the effectiveness and safety of high-intensity, land-based exercise in patients with inflammatory rheumatic conditions, compared with usual care, no intervention, or low-intensity exercise. We aimed to determine whether high-intensity exercise leads to an increase in disease activity, pain intensity, or impairment of function.

Timely referral in Rheumatoid Arthritis (RA) is critical for early diagnosis and initiation of treatment, which are crucial to improve patient outcomes and limit radiographic progression. Optimized referral criteria, whether applied by clinicians or healthcare artificial intelligence systems, can facilitate faster and more accurate decisions regarding patient assessment by a Rheumatologist. Despite this need, a validated and widely adopted referral tool for RA is still lacking.

To compare the clinical efficacy and safety of biological disease-modifying antirheumatic drugs (DMARDs) and Janus kinase(JAK) inhibitors in patients with early rheumatoid arthritis (RA).

Biological treatments are indicated in familial Mediterranean fever (FMF) patients with colchicine resistance or intolerance. Interleukin-1 (IL-1) inhibitors may not yield sufficient efficacy and safety. Interleukin-6 inhibitors (tocilizumab - TCZ) have been suggested to be potentially beneficial. This systematic literature review aimed to evaluate the existing data on the efficacy and safety of IL-6 inhibitors in the treatment of FMF.

Biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) have improved outcomes in rheumatoid arthritis (RA). However, heterogeneity in treatment response remains a significant challenge. Machine learning (ML) may enable improved prediction, but the comprehensive review of ML applications in RA is fragmented and limited. This scoping review synthesizes the literature on ML methods for predicting treatment response to b/tsDMARDs in RA.

To assess the incidence and risk of nephrolithiasis in people receiving uricosuric therapies for gout.

This systematic review and meta-analysis examined how axial spondyloarthritis (axSpA), and its specific disease features, impact sexual function.

To assess the progression of the interstitial lung disease related to RA (RA-ILD) with MTX exposure and to evaluate the lung involvement in RA non-ILD patients with MTX exposure.

Spondyloarthritis (SpA) is a prevalent extraintestinal symptom of inflammatory bowel disease (IBD), impacting up to 20% of patients and considerably contributing to the disease burden. The coexistence of inflammatory bowel disease and spondyloarthritis poses therapeutic problems due to the necessity for simultaneous management of intestinal and musculoskeletal inflammation.

Axial spondyloarthritis (axSpA) exhibits notable sex-related differences, particularly in Asian populations, influenced by genetic, cultural, and healthcare factors. This systematic review and meta-analysis assess sex-specific disparities in axSpA among Asian patients.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder that increases the risk of systemic complications, particularly metabolic syndrome (MetS). MetS, defined by central obesity, hypertension, hyperglycemia, and dyslipidemia, not only raises cardiovascular risk but also worsens the prognosis of RA. This meta-analysis aimed to estimate the global prevalence of MetS in RA patients and identify clinical factors contributing to its occurrence.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a dangerous autoimmune condition that usually requires high-dose glucocorticoids with immunosuppressive agents. Although effective, long-term glucocorticoid use is associated with significant toxicity. Avacopan, a selective inhibitor of C5a receptors, has emerged as a possible glucocorticoid-sparing drug for AAV, potentially offering a safer, more specific approach to treat the disease. This systematic review and meta-analysis aimed to compare the efficacy and safety of avacopan and conventional glucocorticoid-containing regimens for the treatment of AAV.

Sedentary behaviour (SB) is receiving increasing attention as a potential target for behavioural change interventions in people with Rheumatoid Arthritis (RA), to improve RA outcomes. The primary aim of this review was to describe the design and content of existing SB interventions in RA with a focus on the use of digital technology and Behaviour Change Techniques (BCTs). Secondary aims were to understand how SB is conceptualised in intervention studies, and report data on participants' perceptions of acceptable and/or engaging components, adherence, and intervention efficacy.

Immune checkpoint inhibitors (ICIs) have been associated with immune-related adverse events (irAEs), including ICI associated vasculitis (ICI-vasculitis) and ICI associated PMR (ICI-polymyalgia rheumatica (PMR)-like syndromes). We sought to describe the characteristics of ICI-vasculitis and ICI-PMR in individuals treated with ICIs through a systematic review and local case series.
