Thanks for the article. The IV vivo vs human or animal studies varied greatly. The other abxs for Bart are strewn with more neuropathy. Maybe I can try rifampin again orally. Tough to take though. Plus I get diahrea as I've mentioned before and they have concerns of C. difficile. You've got a lot on your plate with AS and sjorgrens. Sp? Gonna make a new post for tx on lyme Bart.
