Background: Herpes simplex virus type 2 (HSV-2) seroprevalence has been shown to be a potential sign of infection in pregnant women, and it could be applied to check HSV-2 transmission. This study evaluated the anti-HSV-2 IgG prevalence in pregnant women who were referred to health centers in Urmia, Northwest of Iran, during 2014-2015. Methods: Serum samples were collected from 86 pregnant wome...

background: the prevalence of anti-neutrophil cytoplasmic antibodies (ancas) and anti-cardiolipin antibodies (anti-cl ab) in behcet’s disease (bd) and also their roles in vascular involvement is controversial. objective: to assess the prevalence of ancas and anti-cl ab as well as their correlations with clinical manifestations in iranian patients with bd. methods: in this case/control study, th...

Introduction: Although the hepatitis E virus mostly causes a self-limited disease in general population, but the disease is more severe in pregnant women. Hepatitis E accounts for about 10% of pregnancy associated deaths in southern Asia. But the prevalence in Iran is almost unclear, so this study is aimed to investigate the seroprevalence of anti-HEV IgG among a population of pregnant women in...

The objective of this study is primarily to compare the performance of the VIDAS(®) Measles immunoglobulin (Ig)G assay to that of two other serological assays using an immunoassay technique, Enzygnost(®) Anti-measles Virus/IgG (Siemens) and Measles IgG CAPTURE EIA(®) (Microimmune). The sensitivity and the agreement of the VIDAS(®) Measles IgG assay compared to the Enzygnost(®) Anti-measles Viru...

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...
