The activities of a number of lysosomal hydrolases were determined in sera from 100 patients with cystic fibrosis (CF), age 2-35 yr, and age-matched controls: beta-hexosaminidase activity was significantly elevated (p less than 0.005) in CF patients from all age groups. alpha-Mannosidase activity was increased only in the older CF patients (greater than 13 yr). The following enzyme activities were not altered in CF serum: alpha-fucosidase, beta-glucuronidase and acid phosphatase. The abnormal patterns of serum alpha-mannosidase and beta-hexosaminidase in CF cannot be explained by pancreatic disease or undernutrition, since serum values of these hydrolases in patients with anorexia nervosa or acute pancreatitis were not altered. However, the altered activities of the alpha-mannosidase and beta-hexosaminidase were proportional to the degree of pulmonary insufficiency in the CF group, indicating that these changes are probably a secondary consequence of the primary disease process. Except for beta-hexosaminidase, because differences in the serum hydrolases in CF do not become apparent until the second decade of life, determinations of lysosomal enzyme activities in serum will probably be of little diagnostic value.
