Aspects of the history of rheumatoid arthritis in the light of recent osteo-archaeological finds.

Rheumatoid arthritis (RA) is one of our most common disabling diseases today. Whether or not RA also existed in ancient times has been questioned and debated in recent years. Supporters of the view of recent onset claim that evidence of the existence of RA in antiquity can be found neither in old literature nor in paintings--and most important--convincing paleopathological finds are lacking. The following presentation reviews the results of an examination of skeletons found during an excavation of a neolithic burial place in the island of Gotland, Sweden. In two skeletons there were marked peripheral changes in both large and small joints. These changes are compatible with in vivo presence of a chronic aseptic polyarthritis. Different diagnostic possibilities for such polyarticular joint disease are discussed. It is suggested that RA might be the most probable alternative although other possibilities cannot be excluded.
