intrinsic-factor and Fatigue-Syndrome--Chronic

A Johns Hopkins University study reveals that HIV-infected men with abnormally low B vitamin blood levels progressed to AIDS twice as fast as those with normal levels. Low levels of B12 have also been found in persons with Chronic Fatigue Immune Dysfunction Syndrome (CFID). Since both ailments have a common virus in HHV-6A, the virus is suspected, although unproven, of causing the inability of the intestines to absorb B12 by affecting intrinsic factor levels.
