Case Presentation: A 63-year-old man presented with fever, thoracalgia, weight loss, diffuse lymphadenopathy, and a massive pleural effusion. Extensive laboratory and radiologic investigations for possible autoimmune, infectious, hematologic, and neoplastic conditions all resulted negative. A lymph node biopsy showed a granulomatous necrotizing lymphadenitis, suspicious for tuberculosis.

Article Synopsis
  • - The study aims to improve the classification and treatment of systemic autoimmune diseases by identifying molecular clusters, moving beyond traditional clinical diagnosis methods.
  • - Researchers analyzed blood samples from 955 patients and 267 healthy controls, discovering four distinct clusters: three linked to inflammatory responses and one related to low disease activity associated with healthy controls.
  • - The findings suggest that these molecular clusters are stable over time and can aid in understanding disease mechanisms and improving treatment strategies, potentially changing how systemic autoimmune diseases are approached in clinical settings.

Objectives: The DETECT algorithm has been developed to identify SSc patients at risk for pulmonary arterial hypertension (PAH) yielding high sensitivity but low specificity, and positive predictive value. We tested whether cardiopulmonary exercise testing (CPET) could improve the performance of the DETECT screening strategy.

Methods: Consecutive SSc patients over a 30-month period were screened with the DETECT algorithm and positive subjects were referred for CPET before the execution of right-heart catheterization.

Dysbiosis has been described in systemic autoimmune diseases (SADs), including systemic lupus erythematosus (SLE), Sjögren's syndrome (SjS), and primary anti-phosholipid syndrome (PAPS), however the biological implications of these associations are often elusive. Stool and plasma samples from 114 subjects, including in SLE ( = 27), SjS ( = 23), PAPs ( = 11) and undifferentiated connective tissue (UCTD, = 26) patients, and geographically-matched healthy controls (HCs, = 27), were collected for microbiome (16s rRNA gene sequencing) and metabolome (high-performance liquid chromatography coupled to mass spectrometry) analysis to identify shared characteristics across diseases. Out of 130 identified microbial genera, a subset of 29 bacteria was able to differentiate study groups (area under receiver operating characteristics (AUROC) = 0.

Intestinal microbiota has been associated with systemic autoimmune diseases, yet the functional consequences of these associations are elusive. We characterized the fecal microbiota (16S rRNA gene amplification and sequencing) and the plasma metabolome (high-performance liquid chromatography coupled to mass spectrometry) in 59 patients with systemic sclerosis (SSc) and 28 healthy controls (HCs). Microbial and metabolic data were cross-correlated to find meaningful associations after extensive data mining analysis and internal validation.

Background: Prokinetics are used to treat enteric dismotility symptoms in systemic sclerosis (SSc) patients, but they often lack adequate efficacy. The most effective prokinetics belonging to the serotonin (5-HT) receptor agonists class were withdrawn due to cardiac toxicity in relation to modest 5-HT receptor affinity. Prucalopride is a high-affinity 5-HT receptor agonist with no major cardiac issues, for which the efficacy in SSc has not yet been assessed.

Objective: HLAs have been extensively associated with SSc susceptibility but their role in the progression of the disease is poorly understood. In 2013 the ACR and European League Against Rheumatism (EULAR) jointly defined criteria for the classification of SSc that allow the early identification of definite SSc patients. In this study we investigated the role of HLA class II antigens in the progression from early to definite SSc.

Objectives: Scleroderma renal crisis (SRC) is a relative rare yet dramatic event in the history of systemic sclerosis (SSc). Several factors that may precipitate or protect from the development of SRC have been described in previous case-control studies. To date, no attempt has been made to evaluate these factors in an observational fashion.
