简要总结
Purpose The purpose of this study is to develop and validate multimodal testing of exocrine pancreatic function (EPF). The investigators will be testing exocrine pancreatic function in patients with cystic fibrosis (CF). Exocrine pancreatic function and imaging will be correlated to age group, genotype, nutritional status and quality of life. Earlier detection of exocrine pancreatic failure in the non classical form of cystic fibrosis may be of therapeutically benefit.
Hypotheses Endoscopic short test can be applied in diagnosing and monitoring exocrine pancreatic function in patients with cystic fibrosis.
New functional testing of exocrine pancreatic function is superior to traditional testing with fecal elastase.
MRI and ultrasound methods can give volume output estimate in cystic fibrosis patients.
Contrast enhanced ultrasound can quantify reduced or delayed pancreatic perfusion and parenchymal changes in cystic fibrosis patients.
Elastography/ CEUS can be used in prediction and monitoring of fibrosis development and development of hepatocellular carcinoma in the liver of cystic fibrosis patients.
Immunohistochemical quantification of secretin/ cholecystokinin (CCK) producing cell in duodenum can be utilized as a model hormonal signaling in cystic fibrosis patients with exocrine pancreatic function.
