Abstract: The present invention relates in a first aspect to a method for the treatment of chronic fatigue syndrome (CFS) comprising administering to a patient in need thereof a therapeutically effective amount of inhibitory or cytotoxic agent against plasma cells. In a further aspect, the present invention relates to a combination of the inhibitory or cytotoxic agent against plasma cells with a B-cell depleting agent or an inhibitor of B-cell activation in the treatment of chron-ic fatigue syndrome. In addition, a combination of an inhibitory or cytotoxic agent against plasma cells and B-Cell depleting agent or an inhibitor of B-cell activation are described. Said combination may be provided in form of a kit comprising suitably effective dosages of said compounds. Further, the use of the compounds or the combination in the treatment of CFS is described.

Abstract: The present invention relates in a first aspect to a therapeutically effective amount of a stimulator of the soluble guanylate cyclase and/or of an activator of the soluble guanylate cyclase for use in the treatment of chronic fatigue syndrome (CFS) in a patient in need thereof. In a further aspect, the present invention relates to a combination of the stimulator and/or activator of the soluble guanylate cyclase with a B-cell depleting agent in the treatment of chronic fatigue syndrome. In addition, a combination of stimulator and/or activator of the soluble guanylate cyclase with B-Cell depleting agent is described. Said combination may be provided in form of a kit comprising suitably effective dosages of said compounds.

Abstract: The present invention relates in a first aspect to a B-cell depleting anti-CD20 antibody or a CD20-binding antibody fragment thereof for the treatment of chronic fatigue syndrome and myalgic encephalomyelitis. In particular, the present invention relates to the use of anti-CD20 monoclonal antibodies or fragments thereof which are preferably humanized for the treatment of chronic fatigue syndrome/myalgic encephalomyelitis in a subject afflicted with said disease.
