text: I haven't heard of this before with fibro - you might want to try the scientific journal databases. I would recommend searching with High Wire or PubMed (links below), although I did a quick search and couldn't find anything with the search terms ("Jo-1 antibody" AND fibromyalgia) on PubMed...\n\nDid come across three articles on High Wire (3rd link below), including one very interesting one about ANA and fibro (will be posting that to my Yahoo group and their wiki!)\n\nGood luck.
