Patients with selective immunoglobulin (Ig) A deficiency have a 10- to 20-fold increased risk of celiac disease. In these patients, serological diagnosis of celiac disease can be difficult, since specific IgA-based assays are usually negative and IgG-specific antibody tests are insufficiently reliable. We describe a girl with selective IgA deficiency who had a troublesome diagnosis of celiac di...
IgA is considered to be the principal Ab involved in defense against pathogens in the mucosal compartment. Using mice with a targeted disruption in IgA gene expression (IgA(-/-) mice), we have examined the precise role of IgA in protective anti-influenza responses after intranasal vaccination. IgA(-/-) mice immunized intranasally with soluble hemagglutinin (hemagglutinin subtype 1) and neuramin...
The diagnostic performances of antiendomysium IgA detected on monkey esophagus and human umbilical cord smooth muscle, of antireticulin IgA, and of antigliadin IgA and IgG were calculated in 74 children with celiac disease (CD) or other gastrointestinal disorders. We also compared four methods for gliadin antibody detection. With a diagnostic specificity of 100%, diagnostic sensitivity was 94% ...
Immunoglobulin A (IgA) deficiency occurs more frequently in patients with celiac disease (CD) than in the general population and can lead to false-negative results in the best serologic test for CD, endomysial IgA (EMA). To evaluate the impact of IgA deficiency on serologic detection of CD in a reference laboratory setting, IgA levels were measured in 510 consecutive serum specimens submitted f...
BACKGROUND There are many reports of incompletely glycosylated O-linked oligosaccharides on the IgA1 hinge region in certain IgA nephropathy patients. In addition, other reports have noted a relationship between tonsillectomy and IgA nephropathy. METHODS Immunoglobulins from extracts of tonsillectomized tissue and other sources were analysed by isoelectric focusing (IEF) and by enzyme-linked ...
PolTmeric IgA in sera was determined by thin-layer gel filtration in patients with IgA ncphropathy, other glomerular diseases, IgA myeloma and healthy adults to determine whethcr serum IgA is composed of a monomcric and/or larger pelymers in these patients. The levels of IgA in sera were also quantitated by laser nephelometer in these patients. Eleven patients with IgA nephropathy (Berger's dis...
چکیده سابقه و هدف: عوارض میکرو و ماکرو واسکولار دیابت به موازات پیشرفت دیابت گسترش می یابند. بسیار با اهمیت است که بتوانیم راه حلی برای تشخیص زودرس بیماری عروق کرونر که علت اصلی مرگ و میر این بیماران می باشد بیابیم. هدف این مطالعه این است که رابطه بین رتینوپاتی و نفروپاتی دیابتی را بررسی کنیم تا شاید بتوانیم رد پای درگیری کرونر را زودتر و آسان تر بیابیم. روش بررسی: در این مطالعه مقطعی، کلیه بیم...
BACKGROUND IgA nephropathy (IgAN), the most common glomerulonephritis worldwide, is characterized by mesangial deposits containing predominantly IgA. IgAN commonly occurs or exacerbates after upper respiratory tract infections such as streptococcal pharyngitis. Certain group A streptococci express M proteins with IgA-binding regions (IgA-BRs). We have previously shown that these IgA-BRs co-loca...
BACKGROUND IgA- and IgG-antibodies against deamidated gliadin peptides (DGP) specifically bind the disease-inducing antigen and might be superior to transglutaminase type 2 (TG2) IgA in monitoring patients on a gluten-free diet (GFD). The aim of this study was to compare the performance of DGP-IgG and DGP-IgA with TG2-IgA of four manufacturers in pediatric celiac patients at diagnosis and durin...
Three Schiff base compounds, N,N′-bis(2,4-dimethoxy benzaldiimine)-1,4-diamino cyclohexane (IGA), N,N′-bis(2,3,4-trimethoxy benzaldiimine)-1,4-diamino cyclohexane (IGA) and N,N′-bis(3,4,5-trimethoxy benzaldiimine)-1,4-diamino cyclohexane (IGA) were synthesized and characterized by the spectroscopic and analytical methods. The electrochemical and photoluminescence properties of the compounds IGA...
