[Sex and age distribution of patients with macroamylasemia found in the daily isoenzyme analysis].
We studied distributions of sex and age for 102 patients with macroamylasemia found in routine isoenzyme analysis. This study was based on a questionnaire to promote understanding of the clinical significance of macroamylase. More than half of the physicians received our report evaluated the information on macroamylase in the questionnaire. Macroamylasemia found in this study consisted of IgA type immunoglobulin in 92% and mostly had high activities in the serum. The back-ground of these patients with macroamylasemia were 10 cases of hepato-biliary disease, 9 cases of diabetes mellitus, 8 cases of autoimmune disease and so on. The frequency of macroamylasemia in males was double than in females and age distribution was not significant in statistic analysis.
