Hi, Strep is a major contributor to arthritis. I have RA and am on an antibiotic therapy which is working wonderfully. Other contributing organisms, among many, are Lyme, chlamydia, mycoplasma. Google Dr. Brown's antibiotic therapy for information.
The use of Antibiotic therapy, especially tetracyclines - and Minocycline in particular, have a theoretical potential place, which is unfortunately not fully substantiated at a clinical level.
Studies are in progress, but existing studies are not dramatically positive.
