Yes, statins can suppress viral infections, and that is why I found a study showing that interferon from viral infections blocked the cholesterol pathway so exciting.
By itself, it tied in the unexplained low pregnenolone finding we had seen for years. It was when I searched the Internet for statins and antiviral and got over a half-million hits that I got really excited.
Statin (cholesterol-blocking) medications, which I believe have been over-marketed to treat high cholesterol and may have caused significant toxicity by blocking the production of CoQ10 and key hormones and worsening muscle inflammation, may actually offer a lot of promise in treating that subset of CFS/FMS with viral infections.
Interestingly, osteoporosis medications called biphosphonates (e.g., Fosamax) also block part of the same pathway as statins, but do so downstream.
Though they have antiviral effects as well, they have a much smaller impact than statins at the dosing typically used in real life.
