Previous studies indicate that 30-50% of chronic urticaria patients have an autoimmune etiology. Clinical diagnosis of autoimmune urticaria is supported with the autologous serum skin test. The purpose of this study was to compare two laboratory tests for measurement of IgG autoantibodies to IgE or IgE receptors and compare the results with the autologous(More)
BACKGROUND Chronic idiopathic urticaria (CU) has been associated with other autoimmune diseases and basophil-activating autoantibodies to FcεRI or IgE. It is unknown whether patients with systemicautoimmune diseases have a similar prevalence of these autoantibodies. OBJECTIVE To compare the prevalences of basophil-activating autoantibodies (elevated CU(More)
Chronic granulomatous disease (CGD) is associated with defective function of the NADPH-oxidase system in conjunction with phagocytic defects which leads to granuloma formation and serious infectious complications. This is often associated with significant morbidity and mortality. The association of defective phagocyte function with other coincidental immune(More)
The quality of an antibody response is determined by both the concentration and the strength of antigen-binding, or avidity, of the antibodies produced. Currently, only antibody concentration is routinely evaluated in the clinical assessment of humoral immunity. Here we studied correlations of avidities and concentrations of antibodies to pneumococcal(More)
The identification of nearly 3,500 cases of chikungunya virus (CHIKV) infection in U.S. residents returning in 2014 and 2015 from areas in which it is endemic has raised concerns within the transplant community that, should recently infected individuals become organ and/or tissue donors, CHIKV would be transmitted to transplant recipients. Thus, tests(More)
Background Herpes simplex virus type 2 (HSV-2; herpes) exacerbates human immunodeficiency virus type 1 (HIV) by unclear mechanisms. These studies tested the impact of HSV-2 on systemic T-cells and HIV reservoirs. Methods Peripheral blood mononuclear cells from HIV-infected women on antiretroviral therapy who were HSV-2 seropositive or seronegative and(More)
