BACKGROUND Toxoplasmosis is well known as an important infection in pregnant women. Although many serologic methods are available, diagnosis of early Toxoplasmosis may be extremely difficult. OBJECTIVE To detect the Toxoplasma IgG antibodies developed at the early stage of infection in pregnant women. METHODS 225 pregnant women, who were in the 2nd to 4th month of their pregnancy, enrolled ...

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-...

different classes of autoantibodies against two antigenic forms of modified low density lipoprotein (mod-ldl) were detected in 140 patients by indirect elisa method. investigated autoantibodes included total immunoglobulins (igt). immunoglobulin g (igg), and immunoglobulin m (igm) against oxidized ldl with copper ions (ox-ldl) and modified ldl with malondialdehyde (mal-ldl) (igt-o) igt against ...

The 83-kDa antigen of Borrelia burgdorferi was expressed as a recombinant protein in Escherichia coli and purified for use in an enzyme-linked immunosorbent assay (p83-ELISA). Antibodies to the 83-kDa antigen of both the immunoglobulin G (IgG) and IgM isotypes could be detected in all stages of Lyme disease. Sensitivity varied, depending on the clinical stage of illness. In early stages, as def...

Normal responses of measles specific immunoglobulins M and G (IgM and IgG) were defined in 10 children with measles. Abnormal responses of measles IgM and IgG were found in both sera and cerebrospinal fluids from three cases of subacute sclerosing panencephalitis. In two patients the serum titres of measles IgM and IgG were abnormally high. The measles IgM was present during prolonged illnesses...

Immunoglobulins isotypes (IgG and IgM) for myelin basic protein (MBP), cerebrosides (CER), gangliosides (GANG) and cardiolipin (CARD) were detected in the cerebrospinal fluid (CSF) from 33 patients with multiple sclerosis (MS), 18 with Guillain-Barré syndrome (GBS) and 30 with systemic lupus erythematosus (SLE). In MS patients occurred positive and significant levels of IgG-MBP in 51.5% (p less...

background: beta-thalassemia major is one of the major health problems in our country. many studies have confirmed the fact that, these patients have an increased susceptibility to bacterial infections. objective: in this study, we have assessed the humoral immune system in 68 thalassemic patients by measuring their serum concentration of immunoglobulin g (igg), igm, iga, c3 and c4 in order to ...
