This research was structured...

Gout and rheumatoid arthritis are associated with subclinical vascular damage, reduced brachial vasoreactivity and coronary microvascular dysfunction: a case-control study

Gout and rheumatoid arthritis (RA) are distinct disorders, but both of these inflammatory arthropaties are associated with a relatively similar risk of atherosclerotic cardiovascular disease. We aimed to assess carotid intima-media thickness (CIMT), flow-mediated vasodilatation (FMD) and coronary flow reserve (CFR) in both disorders to understand and compare the extent of...

Structural changes in the upper trapezius muscle of fibromyalgia patients identified by quantitative ultrasonography: a cross-sectional study

The heterogeneity of symptoms among patients with fibromyalgia (FM) makes the development of standardized diagnostic criteria challenging. No imaging technique has reliably shown FM-related muscle changes to aid clinical assessment. This study aimed to quantitatively analyze the upper trapezius muscle in FM patients using B-mode ultrasonography and blob analysis and to examine...

In this multicenter, cross-sectional study, vaccination levels and related factors were questioned by face-to-face survey method during routine clinical...

The natural course of health-related quality of life in patients with clinically suspect arthralgia: a longitudinal study in progressors and non-progressors to rheumatoid arthritis

Individuals with clinically suspect arthralgia (CSA) are at risk of developing rheumatoid arthritis (RA). It is unknown whether CSA patients have a deprived health-related quality-of-life (HRQoL), how this develops over time, and whether it differs between those who develop RA and those who do not. Using three unique cohorts, we explored the course of HRQoL in CSA patients and...

Effects of treatment with janus kinase inhibitors on coronary microvascular perfusion in patients with rheumatoid arthritis: an observational prospective cohort study

Despite their increasing use and their proven efficacy in the treatment of rheumatoid arthritis (RA), Janus kinase (JAK) inhibitors have been questioned by credible cardiovascular safety concerns. To date, mechanistic links of cardiovascular complications to JAK inhibitors remain largely unexplored. We aimed to investigate the effect of JAK inhibition on coronary microvascular...

Mental Ill-Health in young people with systemic autoinflammatory disease – a scoping review

Systemic autoinflammatory disorders (SAID), immune dysregulation disorders with onset frequently occurring in youth, are defined by unprovoked inflammation. Research suggest inflammation is associated with the pathogenesis of mental ill-health. Separately, research has identified that mental ill-health is prevalent in people with immune dysregulation disorders compared to healthy...

The journey of patients with musculoskeletal complaints in Europe: a cross-sectional European survey

Rheumatic and musculoskeletal diseases (RMDs) are highly prevalent and place a significant socioeconomic burden on healthcare systems. However, their diagnosis and management remain suboptimal. This study aimed to analyze healthcare-seeking behaviors, key touchpoints, access barriers, and diagnostic pathways for individuals experiencing initial or progressive symptoms of RMDs...

Effectiveness of proprotein convertase subtilisin/kexin type 9 inhibitors in managing hypercholesterolemia post-statin-associated immune-mediated necrotizing myopathy: report of five cases and literature review

Immune-mediated necrotizing myopathy (IMNM), a type of inflammatory myopathy, is associated with anti-SRP or anti-3-hydroxy-3-methylglutaryl coenzyme A reductase (anti-HMGCR) antibodies, with statin use potentially inducing statin-associated IMNM (SAIMNM) due to HMGCR targeting. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors may offer a safer alternative for...

High long-term retention rates of Secukinumab in psoriatic arthritis and ankylosing spondylitis: a 3-year interim analysis from the observational, prospective SERENA study, in Greek patients

SERENA is a recently completed, non-interventional, multinational, 5-year study evaluating retention, effectiveness, patient-reported outcomes and safety of secukinumab in patients with moderate-to-severe psoriasis, active psoriatic arthritis (PsA), and active ankylosing spondylitis (AS) treated in real-world settings. Three-year interim data from PsA and AS patients treated in...

High-intensity resistance training in patients with myositis – 1-year follow-up on a randomised controlled trial

Reduced quality of life in patients with myositis is partly due to impairments in muscle strength, muscle endurance and functional capacity. In a recent randomised controlled trial (RCT) (NCT04486261) we showed that high-intensity resistance training improved quality of life, muscle strength, and endurance. This follow-up study aimed to investigate if these improvements remained...

Increased fear of falling in primary Sjögren’s syndrome: kinesiophobia, impaired balance and poor sleep quality as triggering factors

The aim of this study was to explore the link between fear of falling and factors that may contribute to falls in patients with primary Sjögren’s syndrome (pSS). Our study included a total of 67 patients with pSS, aged between 18 and 65. The following tests were performed on each of them by the same researcher: (I) Pain Quality Assessment Scale (PQAS); (II) Berg Balance Scale...

Discounting seems the most toxic dimension of invalidation in fibromyalgia: a cross-sectional analysis

Invalidation, both discounting (overt negative social responses) and lack of understanding (absence of positive social responses), is a common problem in fibromyalgia. The ‘Fibromyalgia Imbalance of Threat and Soothing Systems’ (FITSS) model indicates that different neuropsychological processes may underlie these two components of invalidation. Guided by this model, the aim of...

Placenta biopsies from HC, SLE, pSjD, APS, and patients with...

Reevaluating fibromyalgia diagnosis: a proposal to integrate deep tendon reflex responses into current criteria

Fibromyalgia is a complex condition characterized by widespread pain, fatigue, and various other symptoms. The symptoms of fibromyalgia overlap with numerous other disorders (e.g., infections, chronic fatigue syndrome), which makes diagnosis challenging. Existing diagnostic criteria for fibromyalgia rely particularly on subjective patient reports. Such a limitation may lead to...

Prevalence of psychiatric and sleep disorders and their impact on quality of life in children with hypermobile Ehlers-Danlos syndrome: an observational study

Hypermobile Ehlers-Danlos Syndrome (hEDS) is the most common connective tissue disorder. However, few studies exist on psychiatric and sleep disorders in pediatric patients with hEDS. This study aims to describe psychiatric and sleep disorders and evaluate their impact on health-related quality of life (HRQoL) in pediatric patients with hEDS. As part of a longitudinal study, a...
