My friend in CA is waiting for his stomach biopsy results and I'm wondering if anyone else on this board has had that done? I haven't heard of this leading to large numbers of recoveries yet so I'm assuming it's still a sort of marker that docs aren't sure what to do with yet. My friend said if the results are positive, they will probably put him on Valcyte. I tried Valcyte and I'm convinced all it did was damage me. I'm just getting recovered to where I was before I took it. But I'm curious. Always looking for a way to feel better! But even if this stomach thing helped people improve 20% I'd be thrilled. From MedPage Today: "LOMITA, Calif., Sept. 14 -- Enterovirus, a common pathogen that can cause acute respiratory or gastrointestinal infections, may be a factor in chronic fatigue syndrome, according to researchers here. Action Points Explain to interested patients that this study suggested a link between a common viral infection and chronic fatigue syndrome but the finding requires confirmation. Explain to patients that no microbiologic cause of chronic fatigue syndrome has been established definitively. Eighty-two percent of stomach biopsy samples from 165 chronic fatigue syndrome (CFS) patients tested positive for enterovirus infection versus 7% of samples from controls (P<0.001), John K.S. Chia, M.D., and Andrew Chia, of EV Med Research, reported in the Journal of Clinical Pathology. "Finding enterovirus [viral capsid protein 1] protein in 82% of stomach biopsy samples seems to correlate with the high percentage of CFS patients with GI complaints," Dr. Chia wrote."
