Implication

Case-control study demonstrates cellular immune dysfunction in chronic fatigue syndrome, suggesting a pattern of chronic viral reactivation.

Key Points

To comprehensively evaluate laboratory markers of cellular immune function in individuals diagnosed with chronic fatigue syndrome compared to healthy controls.
Evaluated peripheral blood cellular immune markers in N=30 individuals with clinically defined chronic fatigue syndrome and healthy control subjects.
Assayed natural killer cell cytotoxicity against K562 tumor cells, lymphocyte proliferation responses to phytohemagglutinin and pokeweed mitogen, and mitogen-stimulated interferon gamma production.
Performed phenotypic marker analysis of lymphocyte subsets, including CD56, CD8, CD2, CDw26, CD4, CD29, CD45RA, CD20, CD21, and CD5.
Natural killer cell cytotoxicity per CD56 cell was significantly diminished in CFS cases compared to controls, despite an elevated total count of CD56-positive cells.
Lymphocyte proliferation in response to phytohemagglutinin and pokeweed mitogen, as well as subsequent gamma interferon production, was decreased in most CFS patients.
CFS patients displayed significant elevations in activated CD8 cytotoxic T cells and CD20/CD21 B cells, alongside a significant decrease in the CD4+CD45RA+ suppressor-inducer subset.
