This guideline was developed according to the British Society for Rheumatology Guidelines Protocol by a Guideline Development Group comprising healthcare professionals with expertise in SSc and people with lived experience, as well as patient organization representatives. It is an update of the previous 2015 SSc guideline. The recommendations were developed and agreed by the group and are underpinned by published evidence, assessed by systematic literature review and reinforced by collective expert opinion of the group...

OBJECTIVES: We present the first case of a Majeed syndrome in a girl of central-European ancestry. METHODS: : Patient's medical records were reviewed. A NGS panel for autoinflammatory diseases was performed and the mutation was confirmed by Sanger analysis. Freshly isolated monocytes were activated with LPS +/- ATP. The concentration of inflammatory cytokines was assessed in monocytes supernatants. RESULTS: A 2-year-old girl presented with pain in the lower limbs, increase of acute phase reactants and persistent microcytic anaemia...

OBJECTIVES: This study aims to establish normative data on lower extremity entheseal tendon thicknesses in healthy children and examine correlations with age, gender, and anthropometric measures using musculoskeletal ultrasound. The secondary objective of the study is to investigate the power Doppler properties of entheseal tendons. METHODS: A total of 192 healthy children, aged 5-18 years, participated in this cross-sectional study. Participants underwent detailed physical and ultrasonographic examinations...

OBJECTIVES: Patients with systemic sclerosis present with severe gastroesophageal reflux disease, often refractory to proton-pump inhibitors (PPI) treatment. The aim of the present study was to identify factors associated with PPI-refractory esophagitis. METHODS: We performed a cross-sectional study in a single-center cohort of patients diagnosed with systemic sclerosis. We included patients who underwent an esophagogastroduodenoscopy while on PPI treatment. Patients with PPI-refractory erosive esophagitis were compared with those with endoscopically normal esophageal mucosa...

OBJECTIVE: Bacterial translocation across the gut barrier has been implicated in the pathogenesis of systemic lupus erythematosus (SLE), though underlying mechanisms remain unclear. This study aimed to investigate the role of translocated bacteria in the context of molecular mimicry by utilizing lupus model mice and blood samples from untreated SLE patients. METHODS: Bacterial translocation was evaluated using nonselective cultured mesenteric lymph nodes (MLNs) from B6SKG mice, a lupus model characterized by impaired TCR signalling and gut dysbiosis...

OBJECTIVE: This study aims to evaluate the diagnostic accuracy of CA-125 and PET/CT in detecting cancer among adult patients with idiopathic inflammatory myopathy (IIM). METHODS: We conducted a retrospective study of a single-centre cohort of adult IIM patients enrolled from 2003 to 2020. Data on CA-125 and PET/CT tests conducted within five years of IIM symptom onset were extracted from electronic medical records. The outcomes assessed included true positive, false-positive, true negative, and false-negative results...

OBJECTIVE: The 6-min walk test (6MWT) is a simple test widely used to assess sub-maximal exercise capacity in chronic respiratory diseases. We explored the relationship of 6-min walk distance (6MWD) with measurements of physiological, clinical, radiographic measures in patients with myositis-associated interstitial lung disease (MA-ILD). METHOD: We analyzed data from the Abatacept in Myositis Associated Interstitial lung disease (Attack My-ILD) study, a 48-week multicentre randomized trial of patients with anti-synthetase antibodies and active MA-ILD...

OBJECTIVE: To assess the impact of baseline rheumatoid factor (RF) level on drug concentrations and efficacy of certolizumab pegol (CZP; tumour necrosis factor inhibitor [TNFi] without a crystallisable fragment [Fc]) and adalimumab (ADA; Fc-containing TNFi) in patients with rheumatoid arthritis (RA). METHODS: The phase 4 EXXELERATE study (NCT01500278) was a 104-week, randomised, single-blind (double-blind until week 12; investigator-blind thereafter), head-to-head study of CZP vs ADA in patients with RA...

OBJECTIVE: Raman spectroscopy is proposed as a next-generation method for the identification of monosodium urate (MSU) and calcium pyrophosphate (CPP) crystals in synovial fluid. As the interpretation of Raman spectra requires specific expertise, the method is not directly applicable for clinicians. We developed an approach to demonstrate that the identification process can be automated with the use of machine learning techniques. The developed system is tested in a point-of-care-setting at our outpatient rheumatology department...

OBJECTIVES: Interleukin-12 (IL-12) signalling was proposed in the immunopathogenesis of primary Sjögren's disease. The efficacy of therapies targeting this pathway is currently unclear. Herein, we investigated the associations between circulating proteins involved in the IL-12 and IL-23 signalling pathways on primary Sjögren's disease using mendelian randomization. METHODS: We selected SNPs from protein quantitative trait loci of IL12A, IL12B, IL12Rβ1, IL12Rβ2, and IL23R to examine the association between alterations in their levels and risk of primary Sjögren's disease...

OBJECTIVES: Systemic sclerosis (SSc) is heterogeneous in its clinical presentation. Common manifestations cluster together, defining unique subgroups. This investigation aims to characterize gastrointestinal (GI) phenotypes and determine whether they can be distinguished by temporal progression. METHODS: We examine a well-established SSc patient cohort with a modified Medsger GI severity score measured over time to determine heterogeneity in disease progression...

OBJECTIVES: Idiopathic Inflammatory Myopathies (IIM) are rare and characterized by heterogeneous manifestations and clinical trajectories. Utilizing tele-research methods has the potential to improve participant recruitment and advance the understanding of the disease. We aimed to evaluate disease characteristics in IIM patients throughout the U.S. and compare these parameters between patients recruited remotely through mobile application or website vs those recruited locally in myositis clinics...

OBJECTIVES: Up to a quarter of pregnant individuals with systemic lupus erythematosus (SLE) have small for gestational age (SGA) infants. We aimed to characterize placental pathology associated with SGA infants in SLE. METHODS: We retrospectively analyzed SLE deliveries with placental analysis at UCSD from 11/2018-10/2023, comparing SLE pregnancies resulting in SGA to those that did not, and additionally, to matched pregnancies with SGA but without SLE. RESULTS: Placental analysis was available only for 28/70 (40%) SLE deliveries, which had high rates of adverse outcomes (75%)...
