Nasopharyngeal carcinoma (NPC) is prevalent in Southern China and Southeast Asia, and autoantibody signatures may improve early detection of NPC. In this study, serum levels of autoantibodies against a panel of six tumor-associated antigens (p53, NY-ESO-1, MMP-7, Hsp70, Prx VI, and Bmi-1) and Epstein-Barr virus capsid antigen-IgA (VCA-IgA) were tested by enzyme-linked immunosorbent assay in a t...
OBJECTIVE To examine the relationship of Porphyromonas gingivalis to the presence of autoantibodies in individuals at risk of rheumatoid arthritis (RA). METHODS Study participants included the following: 1) a cohort enriched in subjects with HLA-DR4 and 2) subjects at risk of RA by virtue of having a first-degree relative with RA. None of the study subjects satisfied the American College of R...
INTRODUCTION The anti-Rods and Rings autoantibody recently described in clinical populations is thought to occur in the setting of hepatitis C treatment, specifically in the context of cytidine triphosphate (CTP) and guanosine triphosphate (GTP) synthetic pathway inhibitors, and is important in its potential impact on response to therapy. This study asks the question: what is the epidemiology o...
CONTEXT Human leukocyte antigen (HLA) DQ haplotypes have the strongest genetic association with type 1 diabetes (T1DM) risk. OBJECTIVE The objective of the study was to analyze whether HLA DQ alleles influence the development of antiislet autoantibodies, the progression to T1DM among autoantibody-positive relatives, or both. DESIGN The Diabetes Prevention Trial-1 screened more than 90,000 n...
OBJECTIVES To evaluate the autoantibody in patients without corresponding symptoms, whether these autoantibody are pathognomonic or not. We hypothesised that autoantibody may be reactive to chronic infection, such as tuberculosis (TB). DESIGN Randomised, case-control cohort study. SETTING A tertiary centre in Taiwan. PARTICIPANTS We randomly chose 100 patients out of the data bank of pati...
OBJECTIVE Autoantibody and inflammatory cytokines play crucial roles in the development of systemic lupus erythematosus (SLE); however, the regulation of their production warrants further investigation. This study aimed to investigate the role of basophil activation in the development of SLE based on studies in patients with SLE and spontaneous lupus-prone MRL-lpr/lpr mice. METHODS The phenot...
Background Genetic and environmental risk factors for rheumatoid arthritis (RA) are population dependent and may affect disease expression. Therefore, we studied tender and swollen joint involvement in patients newly diagnosed with RA in four countries and performed a subanalysis within countries to assess whether the influence of autoantibody positivity affected disease expression. Methods P...
BACKGROUND Cardiac troponin (cTn) is an established marker of myocardial infarction. Pronounced heterogeneity and the minute amounts released into the circulation constitute significant challenges for cTn detection. Recently, autoantibody formation to cTn was shown to be common and to interfere with immunoassay performance. In this study, we investigated cTn autoantibodies and cardiac troponin ...
OBJECTIVE There is limited information from large-scale prospective studies regarding the prediction of type 1 diabetes by specific types of pancreatic islet autoantibodies, either alone or in combination. Thus, we studied the extent to which specific autoantibodies are predictive of type 1 diabetes. RESEARCH DESIGN AND METHODS Two cohorts were derived from the first screening for islet cell ...
The progression of autoantibodies (AAbs) to tumor antigens is a humoral immune response that occurs early in development. Serum AAbs are ideal targets for cancer detection given observed sera from patients with various cancers before cancer-associated can be detected, moreover, found up five years symptomatic disease. Although multiple proteomics-based strategies have been developed identify no...
