THE SERUM POLYSACCHARIDE-PROTEIN RATIO (PR) AS A MEASURE OF RHEUMATOID ARTHRITIS ACTIVITY

Abstract
Serial determinations of the serum poly-saccharide-protein ratio (PR) were made in 103 patients with rheumatoid arthritis. PR values were found to correlate with the degree of clinical activity. Improvement in the clinical state of these patients was always accompanied by a decrease in the PR; conversely, elevated PR values occurred whenever the clinical condition became worse. Its use as an objective test in the study of rheumatoid arthritis is suggested.
