Pre-treatment antinuclear antibody positivity, therapeutic efficacy and persistence of biologics in rheumatoid arthritis

Romanian Journal of Laboratory Medicine, 2016
Introduction: Rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) are poor prognostic factors in rheumatoid arthritis (RA). The therapeutic implication of antinuclear antibody (ANA) positivity in RA is still debated. The study aims to

Smoking is associated with the concurrent presence of multiple autoantibodies in rheumatoid arthritis rather than with anti-citrullinated protein antibodies per se:a multicenter cohort study [PDF]

, 2016
BACKGROUND: The contribution of smoking to rheumatoid arthritis (RA) is hypothesized to be mediated through formation of anti-citrullinated protein antibodies (ACPA).

Sjögren Disease—B Cells at the Brink: From Autoimmunity to Lymphomagenesis and the Rise of Novel B Cell–Targeted Therapies

Arthritis &Rheumatology, EarlyView.
Sjögren disease (SjD) is a common systemic autoimmune disorder characterized by inflammation of the exocrine glands, resulting in dryness. Patients frequently exhibit extraglandular manifestations affecting various organ systems. To date, there are no US Food and Drug Administration (FDA)‐approved disease‐modifying therapies for SjD. In this review, we

Autophagy and rheumatoid arthritis: Current knowledges and future perspectives [PDF]

, 2018
Autophagy is a degradation mechanism by which cells recycle cytoplasmic components to generate energy. By influencing lymphocyte development, survival, and proliferation, autophagy regulates the immune responses against self and non-self antigens ...

Distinct HLA Associations for Antibody Multireactivity With Citrulline‐Containing Type II Collagen Epitopes Versus More Limited Antibody Reactivity With Citrulline‐Containing IgG Epitopes in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Anticitrullinated protein antibodies (ACPAs) in rheumatoid arthritis (RA) can be promiscuous, with cross‐reactive binding to many antigens containing short motifs, or private with little cross‐reactivity. Also, ACPA reactivity patterns differ among patients with RA, including for motif‐containing epitopes in important self‐antigens like ...

Distinct effects of complement C4A and C4B copy number in Systemic Sclerosis serological and clinical subtypes

Arthritis &Rheumatology, Accepted Article.
Objective Complement component 4 (C4), encoded by C4A and C4B within the major histocompatibility complex (MHC) on chromosome 6, regulates the immune response and clears immune complexes. Variable copy number (CN) of C4 genes and retroviral HERV‐K element influence its function.

Lifelong evolution of autoreactive plasma cell numbers, affinity and anatomical location in arthritic K/BxN mice

Arthritis &Rheumatology, Accepted Article.
Objective The spontaneous K/BxN mouse model of rheumatoid arthritis has been used extensively to study chronic inflammation, contribution of immune cells, and the primordial role of autoreactive antibodies in disease initiation and severity. Only the ubiquitous enzyme glucose‐6‐phosphate isomerase (GPI) is the target of IgG autoantibodies secreted by ...

Citrullination and carbamylation in the pathophysiology of rheumatoid arthritits

Frontiers in Immunology, 2015
The discovery that citrullination was crucial for the recognition of antigens by the most disease-specific class of autoantibodies in rheumatoid arthritis had a huge impact on studies aimed at understanding autoimmunity in this disease.

Exposure to Occupational Inhalants and the Risk of Developing Rheumatoid Arthritis: A Systematic Review and Meta‐Analysis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint pain, swelling, and stiffness. Although smoking is a well‐established risk factor for RA, the role of occupational inhalants in RA development is less well recognized.
