Background: The recent identification of xenotropic murine leukemia virus-related virus (XMRV) in the blood of patients with chronic fatigue syndrome (CFS) establishes that a retrovirus may play a role in the pathology in this disease.

Knowledge of the immune response might lead to a better understanding of the role XMRV plays in this syndrome. Our objective was to investigate the cytokine and chemokine response in XMRV-associated CFS.

Materials and Methods: Using Luminex multi-analyte profiling technology, we measured cytokine and chemokine values in the plasma of XMRV-infected CFS patients and compared these data to those of healthy controls. Analysis was performed using the Gene Expression Pattern Analysis Suite and the Random Forest tree classification algorithm.

Results: This study identifies a signature of 10 cytokines and chemokines which correctly identifies XMRV/CFS patients with 93% specificity and 96% sensitivity.

Conclusion: These data show, for the first time, an immunological pattern associated with XMRV/CFS.

    Wouldn’t it be more polite to mention the source of this *scoop*? It is copied from the email-bulletin *Help ME Circle; editor Jan van Roijen, who placed this study on MegaUpload.

    I always mention the source of every article in Help ME Circle.

    Hooray for WPI. You continue to be our best hope for answers to this horrible disease. Thank you for you continued efforts under pressure. Hopefully by next year tests will be recognized and covered by insurance and we can begin to use an accepted treatment protocol.
