Rheumatoid factor and anti-citrullinated protein antibodies (ACPA) in psoriatic arthritis (PsA), and skin psoriasis: Relevance and clinical implications

The Egyptian Rheumatologist, 2023
Aim of the work: Anti-citrullinated protein antibodies (ACPAs), is a highly specific markers for rheumatoid arthritis, can also be found in psoriatic arthritis (PsA). This work aimed to look into the frequency of rheumatoid factor (RF) and ACPA in PsA and psoriasis patients without clinical evidence of arthritis (PSO), and to correlate findings with ...

Anti-Carbamylated Fibrinogen Antibodies Might Be Associated With a Specific Rheumatoid Phenotype and Include a Subset Recognizing In Vivo Epitopes of Its γ Chain One of Which Is Not Cross Reactive With Anti-Citrullinated Protein Antibodies

Frontiers in Immunology, 2021
To identify the targets recognized by anti-carbamylated protein antibodies (anti-CarP) in patients with early Rheumatoid Arthritis (RA), to study the cross-reactivity between anti-CarP and anti-citrullinated protein antibodies (ACPA) and to evaluate ...

In Rheumatoid Arthritis Patients, HLA-DRB1*04:01 and Rheumatoid Nodules Are Associated With ACPA to a Particular Fibrin Epitope

Frontiers in Immunology, 2021
ObjectivesRheumatoid arthritis (RA) is associated with HLA-DRB1 genes encoding the shared epitope (SE), a 5-amino acid motive. RA is usually preceded by the emergence of anti-citrullinated protein/peptide antibodies (ACPAs). Citrulline is a neutral amino

Anti-Carbamylated Protein Antibodies as a Reproducible Independent Type of Rheumatoid Arthritis Autoantibodies. [PDF]

PLoS ONE, 2016
A large fraction of the patients with rheumatoid arthritis (RA) develop specific autoantibodies, which until recently were only of two types, rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA).

Anti-carbamylated protein antibodies precede disease onset in monkeys with collagen-induced arthritis

Arthritis Research & Therapy, 2017
Background Rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA) and anti-carbamylated protein (anti-CarP) antibodies are rheumatoid arthritis (RA)-associated autoantibodies. Besides their presence in human serum, anti-CarP antibodies have

Presence of autoantibodies in “seronegative” rheumatoid arthritis associates with classical risk factors and high disease activity

Arthritis Research & Therapy, 2020
Background Rheumatoid arthritis (RA) is classified as seropositive or seronegative, depending on the presence/absence of rheumatoid factor (RF), primarily IgM RF, and/or anti-citrullinated protein antibodies (ACPA), commonly detected using anti-cyclic ...

Prevalence, sensitivity and specificity of antibodies against carbamylated proteins in a monocentric cohort of patients with rheumatoid arthritis and other autoimmune rheumatic diseases [PDF]

, 2016
Antibodies against carbamylated proteins (anti-CarP) have been recently identified in the sera of patients with rheumatoid arthritis (RA). The objective of the study was to evaluate the prevalence, sensitivity and specificity of anti-CarP compared to ...

Low avidity anti-citrullinated protein antibodies (ACPA) are associated with high radiographic progression in rheumatoid arthritis [PDF]

Annals of the Rheumatic Diseases, 2011
Background and objectives Anti-citrullinated protein antibodies (ACPA) are specific for Rheumatoid Arthritis (RA). Their presence is predictive for development to RA and they have been implicated in disease-pathogenesis in animal studies. The biology of the ACPA response and its consequence are poorly studied in humans. We have shown that ACPA display

Light chain skewing in autoantibodies and B-cell receptors of the citrullinated antigen-binding B-cell response in rheumatoid arthritis.

PLoS ONE, 2021
Rheumatoid arthritis (RA) is a chronic autoimmune disease affecting 1% of the world population. RA is associated with the presence of autoantibodies, of which anti-citrullinated protein antibodies (ACPA) are most prominent.

Effect of Etanercept on anti-carbamylated protein antibodies in patients with rheumatoid arthritis [PDF]

, 2015
Rheumatoid Arthritis (RA) is a systemic, chronic inflammatory disease characterized by inflammation of synovial joints and production of autoantibodies such as Rheumatoid Factor and antibodies directed against modified proteins - i.e.
