To prevent unintentional transmission of bloodborne pathogens through organ transplantation, organ procurement organizations (OPOs) screen potential donors by serologic testing to identify human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection. Newly acquired infection, however, may be undetectable by serologic testing. Our objective was to estimate the incidence of undetected...
background: helicobacter pylori (h. pylori) infection is a major cause of chronic gastritis, especially in metabolic syndrome patients. the use of a accessible and easy diagnostic method, can speed up the treatment of this infection this study compared two methods of histology and serology for diagnosis of h. pylori in metabolic syndrome patients. methods : this study was done on 175 metabolic ...
Background Hepatitis B infection is a significant public health challenge despite improvements in vaccination efforts. Patients such as those on chronic immunosuppressive therapy for inflammatory bowel disease (IBD) or rheumatic disease may incur greater risk. The risk of reactivation of hepatitis B while on immunosuppressive therapy may have mortality rates up to 25%. These patients should be ...
Intravenous immunoglobulin (IVIG) is commonly used for a wide range of diagnoses, by multiple pediatric subspecialists. We report two cases of hepatitis B screening results post IVIG infusion, where positive anti-Hepatitis B core antigen serology tests indicated possible occult hepatitis infection, leading to a delay in care. However, serial antibody testing showed results consistent with the p...
The antiglobulin consumption test of Steffen (1954) has been adapted for the detection of Brucella antibodies in human serum. This screening method takes approximately two hours to complete and sera which give a negative result need no further investigations, whilst positive sera should be fully tested by the conventional Brucella serology technique.
Background: Serologic screening of gastric cancer (GC) by serum pepsinogens (sPG) levels and Helicobacter pylori (Hp) sero-status, though highly informative, has provided heterogeneous results. Here, we have evaluated the modifying effects of demographic factors on the risk impact of Hp sero-status/sPG levels in gastric cancer, with particular emphasis on age. Methods: A cross-sectional study w...
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...
Feline coronavirus (FCoV) infects members of the Felidae family with results ranging from seroconversion with no disease to fatal feline infectious peritonitis (FIP). Infection of nondomestic felids with FCoV is of concern, particularly in endangered populations such as cheetahs (Acinonyx jubatus). In this investigation, we tested 342 animals in the Republic of South Africa and Namibia, includi...
Detection of HIV-specific antibodies forms the corner stone for laboratory diagnosis of HIV infections. Serologic methods are routinely used to determine whether a host is infected with HIV, to evaluate the status of infections, and to assist monitoring antiretroviral therapy. Primary diagnosis of HIV infection is commonly accomplished by serology via detection of HIV antibody using a screening...
