Testing for soluble CD30 (sCD30), an indicator of Th2 immune response, is a useful prognostic marker in solid organ transplantation, lymphoproliferative disorders, autoimmunity, and various parasitic diseases. In this study we report the development and validation of a fluorescent microsphere immunoassay for the detection of sCD30 in serum, plasma, and culture supernatants. The dynamic range of...

BACKGROUND The serum level of soluble CD30 (sCD30) is known to be increased with several lymphomas and to correlate with prognosis. Primary effusion lymphoma (PEL) is a highly aggressive malignant lymphoma with poor prognosis, but the existence and significance of sCD30 in PEL have not yet been investigated in detail. OBJECTIVES Since the membrane type of CD30 is frequently expressed on the s...

Soluble CD30 (sCD30), a transmembrane glycoprotein that belongs to the tumor necrosis factor receptor (TNFR) superfamily, has been shown to be associated with various pathological conditions. This study was designed to measure the levels of serum sCD30 in patients with ankylosing spondylitis (AS) and to evaluate the relationships between serum sCD30 levels and other disease severity-related ind...

BACKGROUND We aimed to determine whether serum soluble CD30 (sCD30) could identify recipients at high risk for unfavorable early and late kidney transplant outcomes. METHODS Serum sCD30 was measured on the day of kidney transplantation and on the 4th day posttransplant. We assessed the value of these measurements in predicting delayed graft function, slow graft function (SGF), acute rejection...

Preliminary reports suggested a prognostic significance for serum levels of soluble CD30 (sCD30) in patients with Hodgkin's disease (HD). In this study, we investigated the prognostic impact of sCD30 concentration at diagnosis in relation to the other recognized prognostic parameters in 303 patients with HD observed in three different institutions between 1984 and 1996. sCD30 levels were correl...

The CD30 molecule, a 120 kDa cell surface glycoprotein, is a member of the tumor necrosis factor receptor (TNF-R) superfamily and was originally identified on the surface of Reed-Sternberg cells and anaplastic large cell lymphomas in Hodgkin's disease patients. In addition to lymphoproliferative disorders the expression of CD30 was found in both activated CD8+ and CD4+ Th2 cells which lead to t...

Background. Rejection is the main drawback facing the renal transplant operations. Complicated and overlapping factors, mainly related to the immune system, are responsible for this rejection. Elevated serum levels of sCD30 were frequently recorded as an indicator for renal allograft rejection, while BV virus is considered as one of the most serious consequences for immunosuppressive treatment ...

The soluble form of the CD30 antigen (sCD30), an 88-kd glycoprotein that is released by Hodgkin's-derived cell lines in vitro, can be detected in patients with Hodgkin's lymphoma, adult (HTLV-1+) T-cell leukemia, rare cases of non-Hodgkin's lymphoma, and acute infectious mononucleosis (anti-EBV-IgM+). In a prospective study of 90 consecutive untreated patients with newly diagnosed Hodgkin's dis...

The CD30 antigen seems to play a costimulatory role in maintaining the physiological balance between T-helper (Th)1/Th2 immune responses. In this study, plasma and in vitro soluble CD30 (sCD30) secretion was investigated in patients with coronary artery disease (CAD) as a plausible marker of dysregulated immune response.Twenty one patients with angiographically confirmed CAD and 31 healthy cont...

Plasma-soluble CD30 (sCD30) is the result of proteolytic splicing from the membrane-bound form of CD30, a putative marker of type 2 cytokine-producing cells. We measured sCD30 levels in children with tuberculosis, a disease characterized by prominent type 1 lymphocyte cytokine responses. We postulated that disease severity and nutritional status would alter cytokine responses and therefore sCD3...
