The PFD test for pancreatic disease patients

Area of Science:

• Gastroenterology
• Biochemistry
• Oncology

Background:

• Pancreatic exocrine dysfunction is a hallmark of various pancreatic diseases.
• Accurate assessment of pancreatic function is crucial for diagnosis and management.
• The PABA excretion test (PFD test) is a non-invasive method to evaluate exocrine function.

Purpose of the Study:

• To evaluate the utility of the PFD test in patients with different pancreatic diseases.
• To compare PABA excretion rates in patients with chronic pancreatitis, pancreatic carcinoma, and healthy controls.
• To assess the impact of surgical intervention on PABA excretion in pancreatic carcinoma patients.

Main Methods:

• The PFD test, measuring urinary PABA excretion, was administered to patients with various pancreatic diseases and healthy controls.
• Post-surgical PABA excretion was analyzed in pancreatic carcinoma patients.
• Histopathological examination of pancreatic tissues was performed.

Main Results:

• Urinary PABA excretion was significantly lower in chronic pancreatitis and pancreatic carcinoma patients compared to controls.
• No significant difference in PABA excretion was found between chronic pancreatitis and pancreatic carcinoma patients.
• Post-surgery, pancreatic carcinoma patients exhibited lower PABA excretion than non-pancreatitis, non-pancreatic carcinoma patients, likely due to differences in residual pancreatic tissue.
• Pancreatic tissues from carcinoma patients showed more severe pancreatitis, fibrosis, and fat necrosis compared to controls.

Conclusions:

• The PFD test effectively detects reduced pancreatic exocrine function and quantifies the severity of pancreatic disorders.
• While useful for assessing overall pancreatic health, the PFD test cannot differentiate between specific pancreatic diseases like chronic pancreatitis and pancreatic cancer.
• Histopathological findings correlate with PFD test results, underscoring the impact of pancreatic tissue integrity on exocrine function.
