[Serum amyloid A (SAA) 1, SAA 2 and apolipoprotein E isotype frequencies in rheumatoid arthritis patients with AA amyloidosis].

Abstract

These results suggest the possibilities that SAA 1 alpha may be working protectively against and SAA 1 gamma provocatively for the development of AA amyloidosis in RA. However, there was no significant association between SAA 2 isotype patterns and the development of AA amyloidosis in RA. Furthermore, there was no discernible association between AA amyloidosis in RA and Apo E 4 isotype.
