Abstract
SAA isotypes were examined in a group of patients from Papua New Guinea where there is a very high incidence of amyloidosis. The expression of SAA2ß was more common than observed in patients from Europe/USA but similar to that observed in a group of patients from Malawi with malaria. After examination of matched pairs of patients with and without amyloidosis we could find no evidence for qualitative differences in isotypes present in patients with or without amyloidosis. We have also looked at the isotypes in a group of patients from Lund with rheumatoid disease, with or without amyloidosis, matched for age, sex and duration of disease. There was no qualitative difference in SAA isotype expression in individuals who develop amyloidosis and those who do not. There was no evidence for quantitative differences in SAA1 and SAA2α in patients who had amyloidosis and those who did not. Further studies are in progress on the quantitation of isotypes with arginine at the N-terminal.
