Indirect and qualitative tests of pancreatic function are commonly used to screen patients with cystic fibrosis for pancreatic insufficiency. In an attempt to develop a more quantitative assessment, we compared the usefulness of measuring serum pancreatic lipase using a newly developed enzyme-linked immunosorbent immunoassay with that of cationic trypsinogen using a radioimmunoassay in the assessment of exocrine pancreatic function in patients with cystic fibrosis. Previously, we have shown neither lipase nor trypsinogen to be of use in assessing pancreatic function prior to 5 years of age because the majority of patients with cystic fibrosis in early infancy have elevated serum levels regardless of pancreatic function. Therefore, we studied 77 patients with cystic fibrosis older than 5 years of age, 41 with steatorrhea and 36 without steatorrhea. In addition, 28 of 77 patients consented to undergo a quantitative pancreatic stimulation test. There was a significant difference between the steatorrheic and nonsteatorrheic patients with the steatorrheic group having lower lipase and trypsinogen values than the nonsteatorrheic group (P <.001). Sensitivities and specificities in detecting steatorrhea were 95% and 86%, respectively, for lipase and 93% and 92%, respectively, for trypsinogen. No correlations were found between the serum levels of lipase and trypsinogen and their respective duodenal concentrations because of abnormally high serum levels of both enzymes found in some nonsteatorrheic patients. We conclude from this study that both serum lipase and trypsinogen levels accurately detect steatorrhea in patients with cystic fibrosis who are older than 5 years but are imprecise indicators of specific pancreatic exocrine function above the level needed for normal fat absorption.

Exocrine pancreatic insufficiency is an important cause of chronic malnutrition, secondary to maldigestion-malabsorption, which can be caused in children especially by cystic fibrosis, but also by other much rarer diseases. The case of a 6 months and 3 weeks old male pediatric patient is reported, who was admitted to the clinic for head and forearms bruising. Laboratory findings identified vitamin K deficiency as the cause of the cutaneous hemorrhagic syndrome. Further investigations revealed association of steatorrhea (which is a marker of fat malabsorption), iron-deficiency anemia and hypovitaminosis D, which had been produced by nutritional deficiencies caused by malabsorption syndrome. From the numerous disorders that could be associated with pancreatic insufficiency in children, the following conditions had been excluded: cystic fibrosis (mucoviscidosis), cow`s milk protein intolerance, gluten-sensitive enteropathy (coeliac disease), Shwachman-Diamond syndrome, abetalipoproteinemia, etc. Based upon decreased levels of stool pancreatic elastase in repeated measurements, together with low serum lipase, the final diagnosis of exocrine pancreatic insufficiency was established. Treatment of this case consisted mainly in pancreatic enzyme replacement therapy, but also oral iron supplementation and dietary supplements with fat-soluble vitamins (A, D, E, K). The outcome was favorable, characterized by normalization of intestinal passage, ascending growth curve and normalization of the majority of laboratory tests values that were modified between the time of patient admission to our clinic and initiation of specific therapy (serum level of vitamin K, vitamin D and lipase, coagulation profile, hemoglobin and red blood cell indexes), as well as higher value of fecal pancreatic elastase.

Abstract A 51-year-old man developed a large retroperitoneal tumor with liver and lymph node metastases; there was no radiological evidence of pancreatic involvement. Despite the progression of disease, results of laboratory tests, notably serum amylase, were normal except for minor increases in aspartate aminotransferase and gamma-glutamyltransferase and a marked increase in lipase. The increased lipase was not attributable to formation of macroenzyme. To determine the source of the lipase, we fractionated serum and a tumor biopsy homogenate, using electrophoresis. The lipase pattern obtained from the patient's serum differed from that seen in serum from a patient with acute pancreatitis. Additionally, the lipase pattern obtained from a homogenate of biopsy sample from the retroperitoneal tumor did not match the pattern observed for normal pancreas. Apparently, the source of this increased serum lipase activity was the nonpancreatic tumor.
