Sjögren disease (SjD) is a systemic autoimmune disorder affecting both children and adults, with a wide range of clinical phenotypes. It remains a challenging condition to recognise and diagnose early and manage effectively. The heterogeneous nature of the presentation, variable disease course and overlapping symptoms with other autoimmune conditions often result in delayed diagnosis.

Modulation of Lymphotoxin β Surface Expression by Kaposi's Sarcoma-Associated Herpesvirus K3 Through Glycosylation Interference.

J Med Virol

January 2025

Department of Infection Biology, Global Center for Pathogen and Human Health Research, Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio, USA.

Kaposi's sarcoma-associated herpesvirus (KSHV) employs diverse mechanisms to subvert host immune responses, contributing to its infection and pathogenicity. As an immune evasion strategy, KSHV encodes the Membrane-Associated RING-CH (MARCH)-family E3 ligases, K3, and K5, which target and remove several immune regulators from the cell surface. In this study, we investigate the impact of K3 and K5 on lymphotoxin receptor (LTβR) ligands, LTβ and LIGHT, which are type II transmembrane proteins and function as pivotal immune mediators during virus infection.

Improving cefazolin administration for surgical prophylaxis in reported penicillin allergy: A retrospective study of a health system intervention.

J Allergy Clin Immunol Glob

February 2025

Section of Rheumatology, Allergy, and Immunology, Department of Internal Medicine, Yale School of Medicine, New Haven, Conn.

Background: Cefazolin is the most common first-line antibiotic to prevent surgical-site infections. Patients with penicillin allergy labels often receive alternative antibiotics, which is associated with increased rates of surgical-site infections, multi-drug-resistant infections, and cost.

Objective: We sought to determine whether a hospital-wide guideline recommending first-line surgical prophylaxis in patients with penicillin allergy labels can increase the use of cefazolin without compromising safety.

Background: Anti-citrullinated peptide antibodies (ACPA)-negative (ACPA-) rheumatoid arthritis (RA) presents significant diagnostic and therapeutic challenges due to the absence of specific biomarkers, underscoring the need to elucidate its distinctive cellular and metabolic profiles for more targeted interventions.

Methods: Single-cell RNA sequencing data from peripheral blood mononuclear cells (PBMCs) and synovial tissues of patients with ACPA- and ACPA+ RA, as well as healthy controls, were analyzed. Immune cell populations were classified based on clustering and marker gene expression, with pseudotime trajectory analysis, weighted gene co-expression network analysis (WGCNA), and transcription factor network inference providing further insights.

New Insights on Childhood Lupus Nephritis.

Int J Nephrol Renovasc Dis

January 2025

Autoimmunity Lab, School of Medical Science, Universidade Estadual de Campinas, Campinas, Brazil.

Approximately one in five patients with systemic lupus erythematosus (SLE) has disease-onset during childhood (cSLE). Lupus nephritis is more common in cSLE than adult-onset SLE and is associated with significant and increased morbidity and mortality. In this article, we review lupus nephritis in cSLE, including pathogenesis, diagnosis, biomarkers, and management through PUBMED search between July and December 2024.

Objectives: To promote standardization and feasible measurements of gait speed across the field, we developed a device that used light detection and ranging (LiDAR) technology to measure gait speed from a standing-start testing procedure conducted on a 4-m total walkway. We compared this automated (LiDAR-based) standing-start 4-m gait speed test (AS-4MG) with automated and manual (stopwatch-based) dynamic-start 4-m gait speed tests (AD-4MG and MD-4MG, respectively) on between-method agreement, measurement repeatability, and predictive validity with functional outcomes.

Methods: A sample of 48 community-dwelling adults (mean [SD], 69 [9] years) participated in this method comparison study.

Background: Myasthenia gravis (MG) is strongly associated with thymic tumors, but whether it is also associated with extrathymic cancers is debatable or whether MG can be considered a paraneoplastic disorder for extrathymic cancers.

Methods: This is a retrospective analysis of the MG cohort for 23 years' time (January 2000 to May 2023), extracting cancer rates with clinical, electrophysiological, and biochemical cancer associations and the effect of chronic medications.

Results: We identified 436 patients with MG and 3924 controls.

Objective: In this study, we explored physicians' level of experience with patients with rheumatoid arthritis (RA) who used tobacco; their views on the effects of tobacco use on the efficacy of RA treatments; and their experiences and attitudes with respect to tobacco cessation programs.

Methods: We conducted qualitative, semi-structured interviews of 20 physicians (10 primary-care physicians [PCPs] and 10 rheumatologists).

Results: The physicians had been in clinical practice for a mean of 9.

Systemic lupus erythematosus (SLE) patients are 90% women and over three times more likely to die of cardiovascular disease than women in the general population. Chest pain with no obstructive cardiac disease is associated with coronary microvascular disease (CMD), where narrowing of the small blood vessels can lead to ischemia, and frequently reported by SLE patients. Using whole blood RNA samples, we asked whether gene signatures discriminate SLE patients with coronary microvascular dysfunction (CMD) on cardiac MRI (n = 4) from those without (n = 7) and whether any signaling pathway is linked to the underlying pathobiology of SLE CMD.

Background: Patients with adult T-cell leukemia/lymphoma (ATL) are considered to have worse outcomes after allogeneic hematopoietic stem cell transplantation (allo-HSCT) than patients with other hematological malignancies, owing to high risk of relapse and immunocompromised status. However, no studies have compared transplant outcomes between patients with ATL and those with other hematological malignancies using a large-scale database.

Objectives: To compare transplant outcomes between patients with ATL and those with other leukemias and to identify factors contributing to worse transplant outcomes in ATL patients.

Background: The Clinical Genome Resource (ClinGen) is an international collaborative effort between scientists and clinicians, diagnostic and research laboratories as well as the patient community. Using a standardized framework, ClinGen has established guidelines to classify gene-disease relationships as Definitive, Strong, Moderate, and Limited based on available scientific and clinical evidence. When the genetic and functional evidence for a gene-disease relationship has conflicting interpretations or contradictory evidence, they can be Disputed or Refuted.
