Post Gardasil Heart Failure, Ragged Red Fibers and Thiamine

Ragged red fibers are commonly seen with mitochondrial dysfunction in muscle tissue. The ragged red fibers indicate an accumulation of abnormally functioning mitochondria in the muscle tissue. Though ragged red fibers have been studied extensively in individuals with inherited mitochondrial disease, it is not clear whether this type of damage can be acquired or induced in individuals with or even without mtDNA mutations. Studies in rats, however, have shown that thiamine deficiency does result in the finding of ragged red fibers in muscle tissue, suggesting that this damage can be induced. In view of the many posts on this website discussing the association of thiamine deficiency with Gardasil vaccination, I became very interested and began to search the literature for what was known about the relationship of thiamine with ragged red fibers.
