I can put you both in touch with someone who has PPMS and who used to live in NYC and also a doctor who can treat, but unfortunately lives in Chicago: I don't know anyone nearer.
There have been two trials at Vanderbilt: the first used minocycline or doxycycline, I forget which, and the second rifampicin. My husband is Dr David Wheldon from Bedford UK. He treated me with doxycycline after finding Stratton's patent and then talking with both him and Sriram. He uses Doxycycline because rifampicin is reserved for TB in the UK, so people found prescribing it for unusual reasons are in danger of trouble from the General Medical Council. Also it is stronger and is hard to take for many people.
I took the full-time regime for a year before changing to intermittent therapy. I took doxycycline for six moths then rifampicin for the next six. Unlike doxycycline, rifampicin has no immunomodulation, so it can make it seem like things are getting worse again, for a while.
Let me know if you would like me to contact the people mentioned above.
An Itinerary in Light and Shadow Completed Dr Charles Stratton / Dr David Wheldon abx regime for aggressive secondary progressive MS in June 2007, after four years. Still improving with no relapses since starting. Can't run but can paint all day.
