anti-neutrophil cytoplasmic autoantibodies have been detected in patients with some autoimmune and vascular diseases such as wegner's granulomatosis, polyarthritis nodosa and systemic lupus erythematosus. indirect immunofluorescence technique has been employed to detect these autoantibodies. by this method, two general patterns of antineutrophil cytoplasmic antibodies were seen: a cytoplasmic (...

background: evidences suggest an association between the prevalence of thyroid peroxidase (anti-tpo) and anti thyroglobulin (anti-tg) with recurrent abortions and infertility. iodine deficiency was once endemic in iran and little data is available about the prevalence of these antibodies in different groups of fertile or infertile individuals. objective: this case control study was designed to ...

background: the prevalence of toxoplasma gondii infection in the blood donors has been poorly studied. the aim of this study was to assess the prevalence of acute and chronic toxoplasmosis in blood products. methods: a total of 250 blood products (112 fresh frozen plasma and 138 packed cells) in the blood transfusion institute, shiraz, iran were tested for spe-cific t. gondii antibodies (igg an...

INTRODUCTION Dermatitis herpetiformis (DH) seems to be a chronic immune-mediated inflammatory disease of partially known origin. In light of its known biological functions and its involvement in tissue pathology in other disease states, particularly in nickel-induced allergic contact dermatitis coexisting with DH, it would appear that the central and peripheral response by neutrophils and their...

OBJECTIVE The prevalence of coeliac disease (CD) in Vietnam is unknown. To fill this void, we assessed the prevalence of serological markers of CD autoimmunity in a population of children in Hanoi. SETTING The outpatient blood drawing laboratory of the largest paediatric hospital in North Vietnam was used for the study, which was part of an international project of collaboration between Italy...

BACKGROUND Patients with type 1 diabetes mellitus (T1DM) have an increased risk of celiac disease (CD). Both diseases have a common genetic susceptibility locus in the human leukocyte antigen (HLA) class II alleles. Testing for tissue transglutaminase antibodies (anti-tTG) is highly accurate for a CD diagnosis. OBJECTIVE To determine the frequency of HLA-DQB1*0201/02 and DQB1*0302 alleles and...

Coeliac disease (CD) is characterized by several markers, including anti-transglutaminase auto-antibodies (tTGAb) directed against multiple epitopes of the gliadin protein. We aimed to investigate the correlation among CD duodenal lesions, tTGAb titres and the immunoreactivity against tTG constructs. A total of 345 CD patients (209 females, 136 males, overall median age: 7.3 years) were tested ...

INTRODUCTION Irritable bowel syndrome (IBS) and celiac disease (CD) share some gastrointestinal symptoms. Celiac disease should be considered in a differential diagnosis of IBS. AIM To estimate the prevalence of predispositions to CD in patients with IBS and its subtypes. MATERIAL AND METHODS The study included 48 patients (40 women, 8 men; average age: 41.1 ±14.6 years) with IBS, and a con...

BACKGROUND We prospectively evaluated the usefulness of IgA tissue transglutaminase antibodies (IgA tTG) in the initial diagnosis of celiac disease (CD) and compared its diagnostic potential with that of IgA anti-endomysial antibodies (IgA EMA) and anti-IgA and IgG gliadin antibodies (AGA and AGG, respectively). METHODS Sera of 23 untreated children fulfilling the revised ESPGHAN criteria for...

The majority of celiac disease affected patients are undiagnosed. Since the epidemiology and phenotype of CD is constantly changing towards latent, hyposymptomatic or asymptomatic behavior and since there is an increased risk of complications, early diagnosis and subsequent adherence to gluten-free diet is highly recommended. Multiple serological tests are on the market and the most frequently ...
