PFD Test in SLE & DM Cases for Determination of Pancreatic Exocrine Function / 第三军医大学学报

ABSTRACT

Pancreatic function diagnostant test (PFD) is performed with the oral administration of N-benzoyl-L-tryosyl-P-aminobenzoic acid (BT-PABA) .It is a specific test for the determination of the exocrine function of the pancreas. It can be more reliable if P-aminobenzoic acid absorbing test (PABA) is also performed to eliminate the intestinal, hepatic, and renal factors in PABA absorption and excretion.The authors used the combined method of PFD and PABA to study the pancreatic exicrine function in 32 cases of systemic lupus erythematosus (SLE) and 16 cases of dermatomyositis (DM) . It was found that lowed exocrine function of the pancreas occurred in 9.4% of SLE cases and in 18.8% of DM cases though no definite abdominal symptoms or signs could be observed in those cases. It is suggested that the combined PFD and PABA method be used in early SLE and DM cases to evaluate the pancreatic exocrine function.
