BACKGROUND & AIMS The presence of celiac disease-associated autoantibodies (antiendomysium and antitissue transglutaminase [anti-TG2]) with normal jejunal mucosa indicate potential celiac disease. We performed a prospective, 3-year cohort study to determine the natural history of potential celiac disease in children. METHODS The study included 106 children with potential celiac disease, based...
Background: Helicobacter pylori may cause many gastrointestinal problems in developing countries such as Iran. We aimed to analyze the cost- effectiveness and cost- utility of the test-and-treat and empirical treatment strategies in managing Helicobacter pylori infection. Methods: This was a Markov based economic evaluation. Effect...
BACKGROUND Current practice for diagnosis of Q fever, caused by the intracellular pathogen Coxiella burnetii, relies mainly on serology and, in prevaccination assessment, on skin tests (STs), which both have drawbacks. In this study, C. burnetii-specific interferon γ (IFN-γ) production was used as a new diagnostic tool for previous Q fever, circumventing most of these drawbacks. Our aim was to ...
Sensitive and precise serology assays are needed to measure the humoral response to antigens of respiratory syncytial virus (RSV) following natural infection or vaccination. We developed and evaluated a collection of electrochemiluminescent (ECL) serology assays using four RSV antigens (F, N, Ga and Gb). To assess the merits of ECL technology, the four ECL serology assays were evaluated using a...
The study aims were to determine the prevalence of positive syphilis serology and meningovascular neurosyphilis (NS) in patients admitted with transient ischaemic attack (TIA) and stroke to a tertiary hospital serving a culturally diverse community. A retrospective cohort analysis was conducted using routinely collected administrative data and medical records to identify patients admitted with ...
Abstract Bell's palsy (BP) is an acute, unilateral facial nerve (FNP) that a diagnosis of exclusion, sometimes associated with infectious causes. In this article, we described previously healthy 2-year-old child patient who presented left-sided droop, positive severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) real-time reverse transcription polymerase chain reaction (RT-PCR), SARS-Co...
Objectives: The demonstration of the serological test importance in the diagnosis of the Congenital Toxoplasmosis. The Method: The serological test was performed through the micro enzymatic immunology technique, on a lot of 87, new born suckling babies. Along with the laboratory investigations the babies were also clinical, oftalmological and neuron-imagistic examined. Results: The diagnosis of...
Antibody (IgG) responses to salivary gland homogenate and to a recombinant salivary protein from the sand fly Lutzomyia longipalpis were investigated using sera from children living in an endemic area of visceral leishmaniasis in Brazil. We classified children into four groups according to their responses to Leishmania antigen: (Group I) positive serology and positive delayed type hypersensitiv...
OBJECTIVES To determine the proportion of herpes simplex virus type 1 (HSV-1) and HSV type 2 (HSV-2) in first episodes of genital herpes. To evaluate the use of HSV specific serology for classifying first episodes of genital herpes and for defining HSV serostatus in the patients' sexual partners. METHODS 108 consecutive patients with first episodes of genital herpes seen at three STD clinics ...
