A number of chronic diseases are characterized by decreased NK cell activity, including chronic fatigue syndrome,<14> viral hepatitis,<15,16> HIV/AIDS,<2> and autoimmune diseases such as multiple sclerosis.<17> Stimulation of NK cell activity by larch arabinogalactan has been associated with recovery in certain cases of chronic fatigue syndrome.<18> Viral hepatitis (hepatitis B and C) is also characterized by a decrease in NK cell cytotoxicity<15,16> and therefore these patients may benefit from its stimulation by larch arabinogalactan. In the case of multiple sclerosis, a small 2-year study of patients with the relapsing/remitting type concluded that disease severity was correlated with NK cell functional activity, supporting the hypothesis that NK cells play a role in the immunopathogenesis of this disease.<17> Consequently, stimulation of NK cell cytotoxicity might be of clinical benefit to these patients. Patients with HIV/AIDS develop low CD4 cell counts and often are plagued by opportunistic infections. By virtue of its immune-stimulating properties, larch arabinogalactan has been shown to effect a slight increase in CD4 cell counts, in addition to decreasing susceptibility to opportunistic pathogens.<2>
