The present study was undertaken to detect circulating IgG antibodies to peptide antigens derived from baculoviral IAP repeat-containing protein 5 isoform 2 (BIRC5) and myc proto-oncogene protein (MYC) in cervical cancer. A total of 107 female patients with cervical cancer of stages I and II, and 130 healthy female subjects were recruited for analysis of circulating IgG antibodies to BIRC5 and ...
The need for reliable biomarkers for distinguishing Crohn disease (CD) from ulcerative colitis (UC) is increasing. This study aimed at evaluating the diagnostic potential of anti-GP2 antibodies as a biomarker in Chinese patients with CD. In addition, a variety of autoantibodies, including anti-saccharomyces cerevisiae antibodies (ASCA), perinuclear anti-neutrophil cytoplasmic antibodies (PANCA)...
BACKGROUND AND OBJECTIVES The discovery of different podocyte autoantibodies in membranous nephropathy (MN) raises questions about their pathogenetic and clinical meaning. This study sought to define antibody isotypes and correlations; to compare levels in MN, other glomerulonephritides, and controls; and to determine their association with clinical outcomes. DESIGN, SETTING, PARTICIPANTS, & ...
OBJECTIVES The aim of this study was to detect the presence of IgG against Moraxella catarrhalis β-lactamase in healthy adults, and to determine whether outer membrane vesicles (OMVs) could protect the enzyme from inhibition by anti-β-lactamase IgG. METHODS Transmission electron microscopy was used to detect the presence of β-lactamase in OMVs. Sera were examined by ELISA for specific IgG dir...
OBJECTIVES Anti-citrullinated protein/peptide antibodies (ACPA), a family of antibodies with overlapping specificities, represent a specific marker of rheumatoid arthritis (RA). The aim of the present study is to investigate the prevalence and clinical significance of IgG, IgA and IgM ACPA by a newly described assay employing a viral citrullinated peptide (VCP). METHODS IgG, IgA and IgM anti-...
Therapeutic preparations of polyspecific IgG obtained from plasma pools of a large number of normal donors (IVIg) express anti-idiotypic activity against a wide spectrum of natural and disease-associated autoantibodies. The present study investigated the origin of anti-idiotypic activity against autoantibodies to factor VIII. The neutralizing activity of pools of IgG against patients' anti-fact...
The minimum number of IgG anti-A (or anti-B) molecules detectable on A or B red cells by the antiglobulin reaction was found to be the same-that is, about 150 molecules per red cell-with newborn as with adult cells. Furthermore, the ratio of anti-IgG bound to IgG anti-A (or anti-B) molecules was the same whether the anti-A (or anti-B) molecules were present on newborn or on adult cells and was ...
Background: Glycation of proteins is a non-enzymatic spontaneous process that occurs in diabetes mellitus and aging, altering the structure and function of proteins. IgG undergoes glycation leading to changes in its reactivity to antigen and fixation of complement. Objective: This study aimed at revealing the effect of glycation on the interaction of IgG with anti-IgG using electroimmunoassay...
Results Eleven of 47 (23%) JIA SF samples were positive for the different anti-CCP antibody isotypes. IgM anti-CCP antibodies were positive in 9 JIA patients, including 5 oligoarthritis, 3 IgM RF+ and 1 IgM RFpolyarthritis. IgG antiCCP antibodies were positive in 8 JIA patients, including 4 oligoarthritis, 2 IgM RF+, 1 IgM RFpolyarthritis, and 1 enthesitis-related. Two IgM RF+ polyarthritis pat...
BACKGROUND The aim of this study was to compare the correlation between new diagnostic methodologies for detecting anti-polymyositis/scleroderma (anti-PM/Scl) IgG antibodies associated with myositis and/or systemic scleroderma assays with existing platforms. METHODS Sera from 164 samples previously tested for anti-PM/Scl IgG antibody by immunodiffusion, ID; 171 sera screened for anti-PM/Scl I...
