Summary
Plasma lipase, C-peptide reactivity (CPR) and human pancreatic polypeptide (HPP) responses after ingestion of elemental diet were studied in 27 patients with chronic pancreatitis. These subjects were classified into 3 groups according to ERP findings; minimum or mild (MIP, n=17), moderate (MOP, n=6) and advanced (ADP, n=4). Basal plasma lipase levels in the MIP and MOP patients were significantly higher than that in the controls (P < 0.05). Plasma CPR response (Σ Δ CPR) in MIP cases were significantly higher than that in controls (P < 0.05). Also, plasma HPP response (Σ Δ HPP) in MIP cases were significantly higher than that in controls (P < 0.05). Plasma CPR and HPP responses correlated with the severity of chronic pancreatitis. Fourteen of the 17 MIP patients (82%) showed higher levels of basal lipase or Σ Δ HPP in comparison to the respective normal ranges. This study suggested that the ED test may be more sensitive for detection of mild chronic pancreatitis and that it may be useful for evaluating exocrine and endocrine pancreatic functions in various stages of chronic pancreatitis.
