Alkaline phosphatase, aspartate aminotransferase, and bilirubin values within 30 days of diagnosis of primary systemic amyloidosis. The serum alkaline phosphatase level was increased in one fourth of 474 patients at the time of diagnosis. The aspartate aminotransferase value was increased in one third of patients but rarely reached 100 U/L. Hyperbilirubinemia was an infrequent finding but when present was associated with short survival [5]. (Adapted from Kyle and Gertz [5].)
