At the same time, autoimmune inflammation of the gastric mucosa, in addition to the formation of atrophy and an increase in the risk of stomach cancer, carries additional risks, both in relation to neoplasms (neuroendocrine tumors) and in relation to the deficiency of a number of micronutrients with the involvement of other organs and systems. (encyclopedia.pub)
The role of nutrition in the development of autoimmune inflammation has not been reliably established. (encyclopedia.pub)

Liver biopsy remains an important part of the diagnostic workup of patients with suspected autoimmune hepatitis. (medscape.com)
The CTD screening SPAs display a lower sensitivity than HEp-2 IFA likely due to the limited number of autoantigens, however they can offer an additional diagnostic value when carried out together with IFA. (bmj.com)
Diagnostic Automation SSA (Ro) ELISA test system is a semi-quantitative immunoassay for the detection of IgG antibodies to SSA (Ro) in human sera. (rapidtest.com)
The Diagnostic Automation SSA (Ro) ELISA test kit is designed to detect IgG class antibodies to different autoantigens in human sera. (rapidtest.com)

Autoantigens are markers on cells inside your body that your immune system attacks even though they shouldn't. (clevelandclinic.org)

The pathogenesis of antibodies in severe alcoholic hepatitis (SAH) remains unknown. (elifesciences.org)
The work opens new avenues of understanding for the pathogenesis of severe alcoholic hepatitis and is of great interest to researchers and clinicians in the field. (elifesciences.org)
Memory B-cell and antibody responses to the SARS-CoV-2 spike protein contribute to long-term immune protection against severe COVID-19, which can also be prevented by antibody-based interventions. (bvsalud.org)

During pregnancy, anti-Ro antibodies can cross the placenta and cause heart block and neonatal lupus in babies. (wikipedia.org)
Found in patients with systemic lupus erythematosus (SLE), chronic autoimmune hepatitis, or juvenile idiopathic arthritis (JIA). (rheumatologyadvisor.com)
Follow-up tests for anti-SS-A/Ro and anti-SS-B/La antibodies are recommended for Sjogren syndrome, SLE, subacute lupus erythematosus, neonatal lupus, or congenital heart block. (rheumatologyadvisor.com)

Each of these antibody subtypes binds to different proteins or protein complexes within the nucleus. (wikipedia.org)
In normal physiology, lymphocytes that recognise human proteins (autoantigens) either undergo programmed cell death (apoptosis) or become non-functional. (wikipedia.org)
Detectable antibodies against proteins containing citrulline were found in patients with rheumatoid arthritis. (diff.org)

Antineutrophil cytoplasmic antibodies (ANCAs) are sensitive and specific markers for vasculitides. (hindawi.com)
It has been demonstrated that antineutrophil cytoplasmic antibody (ANCA) positivity could be detected in many cases of vasculitis associated with viruses. (hindawi.com)

Latent autoimmune diabetes in adults is a slow-progressing form of autoimmune diabetes. (livingwithdiabetes.info)

Because symptoms of arthritis are common in autoimmune hypothyroidism, joint pain has long been listed as a symptom of hypothyroidism. (diff.org)
Some researchers are questioning whether hypothyroidism is responsible for arthritic symptoms and suspect that these symptoms may be caused by other co-existing autoimmune rheumatological conditions. (diff.org)

Autoantigens are substances of the patient's body that develop antigenic activity and hence destroy the patient's body cells and tissues. (sanfoundry.com)

Autoimmune hepatitis may present as acute or chronic hepatitis or as well-established cirrhosis. (medscape.com)
It can also be used to rescue patients with acute liver failure caused by autoimmune hepatitis. (medscape.com)

Approximately 400 million individuals are infected with hepatitis B virus (HBV) globally [ 1 , 2 ] and 1 million patients die annually due to HBV-associated complications, such as liver cirrhosis and hepatocellular carcinoma [ 3 , 4 ]. (hindawi.com)

We analyzed immunoglobulins (Ig) in explanted livers from SAH patients (n=45) undergoing liver transplantation and tissue from corresponding healthy donors (HD, n=10) and found massive deposition of IgG and IgA isotype antibodies associated with complement fragment C3d and C4d staining in ballooned hepatocytes in SAH livers. (elifesciences.org)
4. Plasma cell antibodies bind to gliadin bound to enterocytes, tissue transglutaminase and reticular fibers surrounding gut smooth muscle (endomysial ab's). (slideshare.net)
The cells and tissue they end up attacking are called autoantigens. (accessh.org)

Titers may be lower in children and still indicate a positive test for autoimmune hepatitis type 1 (AIH-1). (medscape.com)
Negative titers for anti-smooth-muscle antibody (ASMA) are expected in healthy individuals. (medscape.com)

6, 7, 8] As such, the specificity of these antibodies to smooth muscle was questioned, especially when they were shown to also react to striated muscle and renal, thymic, and glomerular cells. (medscape.com)
