Those of you who are thinking your RA might have a connection to leaky gut should look into probiotics. I have just started this line of research, and have seen RA come up in the probiotics research. Don't have any links to articles I've read though.
Am trying out Align, a brand of bifido infantis at the moment. This strain has been used in a
trial involving cfs patients and was shown to effect some inflammatory cytokine levels. A quick check on PubMed gives a list showing papers on arthritis and various probiotics (
here) I didn't read them but some look interesting.
