BACKGROUND Antibody serology is an important tool in the investigation of celiac disease (CD), but does not always correlate with mucosal appearance in the small intestine. Patients with positive CD serology but normal mucosa (Marsh 0) are at increased risk of future CD. In this study we describe a model for identifying and characterizing individuals with normal mucosa but positive CD serology....
OBJECTIVE Previous US-based economic models of noninvasive tests for diagnosis of Helicobacter pylori infection did not consider patient adherence or downstream costs of continuing infection. This analysis evaluated the long-term cost-effectiveness of the urea breath test (UBT), fecal antigen test (FAT), and serology for diagnosis of H. pylori infection after incorporating information regarding...
AIMS Serological analyses of viral infection in suspected myocarditis are still widely used, although convincing evidence for their value is lacking. We determined prospectively the diagnostic value of virus serology in comparison with endomyocardial biopsy (EMB) including viral genome detection and immunohistochemistry in patients with clinically suspected myocarditis. METHODS AND RESULTS Vi...
DNA methods have resulted in improved renal allograft survival rates in cadaveric renal transplantation. This paper describes the impact of DNA typing by PCRSSP on a living related renal transplant (LRRT) programme. It evaluates error rates in serology, acute rejections, graft function and survival rates between the two typing methods. Serological typing was done on CTS 120 antisera Class 1 and...
BACKGROUND Changing perspectives on the natural history of celiac disease (CD), new serology and genetic tests, and amended histological criteria for diagnosis cast doubt on past prevalence estimates for CD. We set out to establish a more accurate prevalence estimate for CD using a novel serogenetic approach. METHODS The human leukocyte antigen (HLA)-DQ genotype was determined in 356 patients...
Background & Aims: Given that H. pylori infection increases the inflammation of the stomach and duodenum, stomach and duodenal ulcer and gastric adenocarcinoma risk in children, the main purpose in this study was to compare the accuracy of serology and rapid urease test in diagnostic of H. Pylori in children. Materials & Methods: This cross-sectional study was a diagnostic test evaluation th...
Introduction: Cochlear implant is an appropriate treatment for deaf children. Rare complications have been reported for this surgery and facial nerve paralysis is one of them with an incidence rate of 0.71%. The aim of this study was to investigate the positive serology and role of Herpes simplex type I virus in patients with Cochlear implant and facial nerve paralysis after surgery. Materia...

infectious bronchitis (ib) is a very contagious disease caused by a coronavirus (ibv). in chickens, thevirus affects the respiratory, reproductive, and urinary systems. this study was carried out to determine theseroprevalence of anti-ibv antibodies in domestic village chickens. serum samples of 300 domestic villagechickens from esfahan (centeral iran) were collected and examined for the presen...
hepatitis b virus (hbv) infection is the most common cause of end stage liver disease in iran and in golestan province. large-scale population-based prospective cohort studies with long term follow-up are the method of choice to accurately understand the natural course of hbv infection. to date, several studies of hbv epidemiology, natural history, progression to cirrhosis and association with ...
