Four patients from 4 to 24 years of age (3 males, 1 female) with generalized lymphadenopathy, hepatosplenomegaly, and intermittent fever associated with chronic active Epstein-Barr virus (EBV) infection were investigated. Laboratory data showed polyclonal gammopathy and a tendency for bone marrow suppression. Noteworthy were the extremely elevated immunoglobulin G (IgG) antibody titers to Epstein-Barr viral capsid antigen (VCA) (range, 10,240-81,920) and early antigen (EA) (range, 1,280-40,960). All patients had IgA antibodies to VCA and EA. Subtle, heterogeneous immune functional defects were observed in all four patients. Another unusual feature was our inability to establish spontaneous or B95-8 EBV-immortalized lymphoblastoid cell lines (LCLs) due to a marked cytopathic effect (CPE). Thus, we investigated for other viruses. Both IgG and IgM antibodies to adenovirus type-2 (Ad-2) were positive by enzyme-linked immunosorbent assay (ELISA) and immunofluorescence (IF) test, suggesting recent or activated Ad-2 infection had occurred. Dual active EBV and Ad-2 infections were likely etiologic in this severe chronic active EBV infection syndrome.

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D003588	Cytopathogenic Effect, Viral	Visible morphologic changes in cells infected with viruses. It includes shutdown of cellular RNA and protein synthesis, cell fusion, release of lysosomal enzymes, changes in cell membrane permeability, diffuse changes in intracellular structures, presence of viral inclusion bodies, and chromosomal aberrations. It excludes malignant transformation, which is CELL TRANSFORMATION, VIRAL. Viral cytopathogenic effects provide a valuable method for identifying and classifying the infecting viruses.
