Objective: A pathogenetic role of CD8+ T lymphocytes in radiographic axial spondyloarthritis (r-axSpA) and other spondyloarthritis (SpA) is sustained by genome-wide association studies (GWAS) and by the expansion of public T cell clonotypes in the target tissues. This study investigates the migration of CD8+ T cells, along with their phenotype and functions in patients with r-axSpA and psoriatic arthritis (PsA).

Methods: Peripheral blood CD8+ and CD4+ T cells were isolated from r-axSpA (n= 128), PsA (n= 60) and rheumatoid arthritis (RA, n= 74) patients and healthy donors (HD, n= 79).

Institute for Immunodeficiency, Center for Chronic Immunodeficiency (CCI), Medical Center, Faculty of Medicine, University of Freiburg, Freiburg, Germany.

Introduction: Human Cytotoxic-T-lymphocyte-antigen-4 (CTLA-4) insufficiency caused by heterozygous germline mutations in is a complex immune dysregulation and immunodeficiency syndrome presenting with reduced penetrance and variable disease expressivity, suggesting the presence of disease modifiers that trigger the disease onset and severity. Various genetic and non-genetic potential triggers have been analyzed in CTLA-4 insufficiency cohorts, however, none of them have revealed a clear association to the disease. Multiple HLA haplotypes have been positively or negatively associated with various autoimmune diseases and inborn errors of immunity (IEI) due to the relevance of MHC in the strength of the T cell responses.

Interleukin-32 positive immune and resident cells in kidney samples from lupus patients: a pilot study.

Front Immunol

January 2025

Rheumatology Unit, Department of Clinical Internal, Anesthesiologic and Cardiovascular Sciences, "Sapienza" University of Rome, Rome, Italy.

Introduction: Lupus nephritis (LN), caused by immune complexes produced or deposited from the bloodstream, is one of the most severe features of Systemic Lupus Erythematosus (SLE) leading to an increased morbidity and mortality. Toll like receptors (TLRs), such as TLR3, TLR7 and TLR9, may play a key role in its pathogenesis. Interleukin-32 (IL-32), a cytokine involved in both innate and adaptive immune responses, has been widely considered in autoimmune-inflammatory rheumatic diseases.

Objectives: To develop an EULAR training model for education in synovial tissue biopsy (STB) under ultrasound guidance (UG) following a stepwise approach: (1) development of educational material on UGSTB in large and small joints; (2) assessment of the validity, reliability and feasibility of the UGSTB educational procedure on cadaveric specimens; (3) validation of this procedure in live patients.

Methods: Using a nominal group (NG) and a DELPHI consensus methodology, educational audio-visual (AV) material and minimal requirements for education in UGSTB were developed by an expert panel. Then the experts performed an UGSTB on cadaveric joints using the developed approach.

CLL patients face increased vulnerability to COVID-19 because of weakened immune systems from comorbidities and treatments. Therefore, the need for these patients of vaccination is of outermost importance. In our study we have evaluated T cell-mediated responses to COVID19 vaccines by performing the activation-induced markers (AIM) assay which allows to determine spike-specific CD4+ and CD8+ T cell responses.

This study investigates the association between the Metabolic Score for Visceral Fat (METS-VF) and chronic kidney disease (CKD), assessing METS-VF as a potential predictor of CKD risk. Utilizing data from the 1999-2018 National Health and Nutrition Examination Survey (NHANES), this cross-sectional study included 24,387 adult participants. Multivariable logistic regression, restricted cubic spline models, and threshold effect analyses were employed to explore the relationship.

Resensitization - Should repeat testing be performed in patients undergoing penicillin allergy evaluations? A Pro-Con Debate.

J Allergy Clin Immunol Pract

Allergy Unit, Hospital Regional Universitario de Málaga, Málaga, Spain; Allergy Research Group, Instituto de Investigación Biomédica de Málaga y Plataforma en Nanomedicina-IBIMA Plataforma BIONAND, Málaga, Spain; Departamento de Medicina, Universidad de Málaga-UMA, Málaga, Spain.

Evaluating penicillin allergy labels and expanding access to preferred treatment options safely is of critical public health importance. Most patients with penicillin allergy labels are not allergic, and even in those with verified allergy, sensitization wanes over time. However, sensitization is complex and while a patient may have a negative penicillin allergy evaluation (including a drug challenge), resensitization can occur, raising a risk of a subsequent reaction upon exposure.

Background: For severe systemic rheumatic diseases (SRDs), therapeutic plasma exchange (TPE) may be applied as a rescue therapy; it usually combined with intravenous immunoglobulin (IVIG) or intravenous methylprednisolone pulse (IVMP) in severe SRDs. However, the necessity of this combination treatment strategy in SRDs remains uncertain.

Objective: This retrospective study aimed to evaluate the effectiveness of TPE alone versus TPE combined with IVIG/IVMP in treating severe SRDs.

Introduction: The pharmacological management of inflammatory arthritis often requires choices that involve trade-offs between benefits, risks and other attributes such as administration route, frequency and cost. This living systematic review aims to inform international clinical guidelines on inflammatory arthritis by creating an evidence map of patient preference studies concerning the trade-offs in pharmacological management of inflammatory arthritis.

Methods And Analysis: We will include published and peer-reviewed full-text studies in any language that quantitatively assess preferences of patients for the pharmacological management of inflammatory arthritis (rheumatoid arthritis, spondyloarthritis and juvenile idiopathic arthritis).

Enhancing single-cell transcriptomics using interposed anchor oligonucleotide sequences.

Commun Biol

January 2025

Botnar Research Centre, Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, National Institute of Health Research Oxford Biomedical Research Unit (BRU), University of Oxford, Oxford, UK.

Single-cell transcriptomics, which utilises barcodes and unique molecular identifiers (UMIs) for polyA+ mRNA capture, is compromised by oligonucleotide synthesis errors. To address this, we modified the oligonucleotide capture design and integrated an interposed anchor between the barcode and the UMI. This design significantly reduces the need to discard reads due to synthesis inaccuracies.
