Pharmaceuticals and Mitochondrial Damage / Peripheral Neuropathy
I think that the article out of Johns Hopkins is great, and I greatly appreciate the research that has been done. However, I suspect that the researchers missed an opportunity in not noting that drugs that deplete mitochondrial DNA are responsible for many cases of mitochondria related peripheral neuropathy.
The damage to mitochondria done by NRTIs is well documented.
Other drugs, including fluoroquinolone antibiotics – Cipro/ciprofloxacin, Levaquin/levofloxacin, Avelox/moxifloxacin and Floxin/ofloxacin – are also well-documented as being destructive to mitochondria AND causing peripheral neuropathy.
In the article, Calcium Signals Are Affected by Ciprofloxacin as a Consequence of Reduction of Mitochondrial DNA Content in Jurkat Cells, it is noted that ciprofloxacin, a fluoroquinolone depletes mitochondrial DNA content. It is also noted in the article, Delayed cytotoxicity and cleavage of mitochondrial DNA in ciprofloxacin-treated mammalian cells, that ciprofloxacin treated cells show a loss of mitochondrial DNA.
Though Delayed cytotoxicity and cleavage of mitochondrial DNA in ciprofloxacin-treated mammalian cells was published in 1996, it was not until 2013 that the FDA added the risk of permanent peripheral neuropathy to the warning labels for fluoroquinolones. The case study, Permanent Peripheral Neuropathy: A Case Report on a Rare but Serious Debilitating Side-Effect of Fluoroquinolone Administration illustrates the severity of peripheral neuropathy brought on by (the mitochondrial damage done by) fluoroquinolones.
