Ann Clin Res. 1975 Jun;7(3):183-94.


The subject of this paper is a 5-year follow-up of 50 women found with Rose-Waaler Titre greater than or equal 1 : 10 or with a Acryl Fixation Titre greater than or equal 1 : 10 in a general health survey conducted in the Reykjavik area in 1968-1969. The average annual incidence of RA was 2.3 percent. Of four women who died during the follow-up period, three were amongst those with the highest titres. Two of the decreased had cancer mammae and one had lung cancer. Changes in RF-titres and New York Criteria are also discussed. It is suggested that RF-positives could be divided in three different riskgroups.
