BACKGROUND: Chlamydia pneumoniae has been associated with cardiovascular disease. However, studies on the presence of chlamydial antibodies and intima-media thickness (IMT) or future ischemic events are inconclusive. We examined the relation between circulating antibodies to chlamydial lipopolysaccharide (cLPS Ab), IMT and the occurrence of ischemic events during follow-up in patients ...

Autoantibodies in patients with paraneoplastic neurological syndromes (PNS) have been reported to be predominantly IgG1 and IgG3 isotypes. However, no data are available about the IgG subclass distribution of the total serum IgG in these patients. Therefore, we investigated the IgG subclass distribution (given as percentage of total IgG) in ...

Tissue transglutaminase (tTG) is a major autoantigen recognised by IgA anti-endomysial antibodies (IgA EMA). Enzyme linked immunosorbent assays (ELISA) for IgA anti-tissue transglutaminase antibodies (IgA tTG) have therefore been developed as an alternative serological screening test to IgA EMA for coeliac disease (CD). The use of human tTG (h-tTG), as ...

Eighteen cases of laparotomy-proven acute necrotizing jejunoileitis were treated during the period 1992-1998. Routine laboratory investigations and bacteriological studies were non-contributory towards establishing an etiological basis for the diagnosis. Superior mesenteric artery digital subtraction angiography, carried out in five patients, demonstrated extensive neovascularization. IgG, IgM and IgA were normal in ...

Radiometal-labeled monoclonal antibodies are retained longer in tumors than iodinated antibodies, leading to their increased use for radioimmunotherapy. Dissociation of radioiodine from the antibody during metabolism has been documented. We now report metabolites in the plasma of lymphoma patients given 111In- and 90Y-2-iminothiolane-2-[p-(bromoacetamido)benzyl]-1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid-Lym-1 (111In/90Y-2IT-BAD-Lym-1). Nineteen patients with non-Hodgkin's lymphoma ...

The frequency of immune heparin-induced thrombocytopenia (HIT) varies among prospective studies. It is unknown whether this is caused by differences in the heparin preparations, the patient populations, or the types of serologic assay used to confirm the diagnosis. Seven hundred forty-four patients were studied from 3 different clinical treatment settings, ...
