Pancreatic elastase is an enzyme produced by the pancreas that aids in the digestion of proteins. It is an important marker in assessing the function of the pancreas and diagnosing exocrine pancreatic insufficiency (EPI), a condition where the pancreas does not produce enough digestive enzymes. The stool elastase test is commonly used to measure pancreatic elastase levels. This non-invasive test helps determine if the pancreas is functioning properly, with lower levels indicating pancreatic exocrine insufficiency. EPI can cause symptoms such as belly pain and digestive problems and can lead to malnutrition if left untreated. Treatment for EPI typically involves pancreatic enzyme replacement therapy (PERT), which helps improve digestion and nutrient absorption. Prompt diagnosis and treatment of EPI can alleviate symptoms and prevent complications associated with malnutrition.
Elastase is an enzyme classified as a serine protease that is involved in breaking down proteins, particularly elastin found in connective tissue. It preferentially cleaves at the C-terminus of specific amino acids and has the ability to induce the disintegration of the axoneme in the presence of ATP. Elastase is also expressed in neutrophils and plays a crucial role in immune responses. Overall, elastase is an essential enzyme with specific functions in protein degradation and various biological processes.
