ABSTRACT Assessment of antibody responses to Epstein-Barr virus (EBV) antigens has been used to assist in nasopharyngeal carcinoma (NPC) diagnosis by several methods. In this study, we evaluated an in-house Luminex multianalyte profiling (xMAP) technology and commercial enzyme-linked immunosorbent assay (ELISA) kits for serological examination of EBV-specific antibody responses in 135 NPC patients and 130 healthy controls. Four EBV biomarkers were measured: immunoglobulin A (IgA) against viral capsid antigen (VCA), EBV nuclear antigen 1 (EBNA1), diffused early antigen (EA-D), and IgG against EA-D. The sensitivities and specificities of the four markers ranged between 71.5 and 90% for xMAP assays and 80 and 92% for ELISA. Logistic regression analysis revealed that the combined markers in the xMAP assay had overall sensitivity and specificity values of 82% and 92%, respectively. The correlation coefficient (r) values for the xMAP assay and ELISA were lowest for IgA-VCA (0.468) and highest for IgA-EBNA1 (0.846); for IgA-EA-D and IgG-EA-D, the r values were 0.719 and 0.798, respectively. The concordances of the two methods for NPC discrimination were good (79 to 88%). Our results suggest that both the xMAP assay and ELISA are satisfactory for EBV antibody evaluation when multiple antigens are included.

Multiple Sclerosis Patients

Cerebrospinal fluid and serum levels and intrathecal synthesis of anti-Epstein—Barr virus (EBV) IgG were measured by enzyme-linked immunosorbent assay in 80 relapsing—remitting multiple sclerosis patients grouped according to clinical and magnetic resonance imaging (MRI) evidence of disease activity. Eighty patients with other inflammatory neurological disorders (OIND) and 80 patients with non-inflammatory neurological disorders (NIND) served as neurological controls. Cerebrospinal fluid concentrations were higher in OIND than in multiple sclerosis ( p < 0.0001) and NIND ( p < 0.01) for anti-viral-capsid-antigen (anti-VCA) IgG, in multiple sclerosis than in NIND ( p < 0.01) and in OIND than in NIND ( p < 0.05) for anti-EBV nuclear antigen-1 (EBNA-1) IgG. Serum levels were more elevated in OIND than in multiple sclerosis ( p < 0.05) and in MRI inactive than in MRI active multiple sclerosis ( p < 0.0001) for anti-VCA IgG, and in multiple sclerosis than in OIND and NIND ( p < 0.01) for anti-EBNA-1 IgG. Serum titres of anti-VCA and anti-EBNA-1 IgG were also positively ( p < 0.05) and inversely ( p < 0.001) correlated, respectively, with the Expanded Disability Status Scale. An intrathecal IgG production of anti-VCA and anti-EBNA-1 IgG, as indicated by Antibody Index, was present only in a limited number of multiple sclerosis patients and controls (range from 1.3 to 6.3%). These findings do not support a direct pathogenetic role of EBV-targeted humoral immune response in multiple sclerosis.

A new immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) based on the recombinant Epstein-Barr virus (EBV) matrix protein was developed. Compared to indirect immunofluorescence for the detection of IgM antibody to the EBV capsid antigen on clinical specimens, the sensitivity and specificity of the new IgM ELISA were 96 and 96%, respectively.

An immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) was developed by using a 24-amino-acid peptide of the 18-kDa Epstein-Barr virus (EBV) viral capsid antigen (VCAp18). IgM detection was increased by 23% by using this antigen. Detection of IgM antibodies to the EBV proteins in the new ELISA was 100% specific and 95% sensitive.

18186 Background: Pulmonary lymphoepithelioma-like carcinoma (PLELC) belongs to large cell sub-type of non-small cell lung cancer (NSCLC) with just about 160 cases reported previously. Its epidemiology, prognosis and therapeutic approach is evidently different from other NSCLCs. EBV infection is seen in 100% of Asian PLELC patients whenever tested. The aim of this study was to analyze serum antibodies level against EBV in PLELC patients. Methods: Sera of all seven patients with re-confirmed PLELC from a single institute in Canton, China in the past 4 years were collected. Serum levels of 8 different antibodies against EBV (Epstein-Barr virus): EBNA1 (EBV nuclear antigen 1- IgA and IgG), Zta (Bam Z transactivator antigen-IgA and IgG), VCA-p18 (Viral capsid antigen-p18-IgA and IgG), VCA-antigen complex (VCA-IgA) and Early antigen complex (EA-IgA ) were measured in each of these patients using enzyme-linked immunosorbent assay and Immunoenzymatic assay respectively. Results: Out of 7 cases, 6 showed high EBNA-1 level, 4 showed high zta, 3 showed high VCA-p18, 3 showed high titer of VCA complex and 2 showed high EA complex titer ( Table 1 ) Conclusions: Though small sample size, this is the first study in this depth ever to conclude that sera of all Asian patients with pulmonary LELC have high antibody titers against EBV. The infection mainly is latency II type as seen in Nasopharyngeal carcinoma and Hodgkin’s disease as well. A small portion of PLELC express lytic products such as Zta, EA and VCA. The authors assume that pre-therapeutic measurement of serum levels of anti-EBV antibodies (at least 2 kinds) is highly warranted in suspected Asian NSCLC patients. Positive result strongly puts PLELC into differential diagnosis. [Table: see text] No significant financial relationships to disclose.
