This study was performed to investigate the behavior of phospholipase A2 (PLA2) in serum and urine of patients with chronic pancreatic diseases and to ascertain whether any factors influenced the results. In 30 controls, 45 patients with pancreatic cancer, 54 with chronic pancreatitis, and 64 with extrapancreatic diseases, serum and urinary PLA2, pancreatic isoamylase and RNase, and urinary N-acetylglucosaminidase (NAG) were measured. Serum PLA2 levels were higher in patients with chronic pancreatitis than in all the other groups. In our patients, only occasionally was urinary PLA2 elevated, the increase occurring almost exclusively in the presence of an acute inflammatory disease, e.g., relapsed chronic pancreatitis or active inflammatory bowel disease. A correlation was found between serum PLA2 and serum RNase, an indicator of tissue damage, but not between serum PLA2 and pancreatic isoamylase. Urinary PLA2 output was correlated with its renal input and with RNase output. No correlation was found between PLA2 output and pancreatic isoamylase or NAG urinary excretion. In conclusion, (1) the determination of serum PLA2 activity may be an aspecific test of pancreatic disease; (2) PLA2 urinary excretion occasionally increases, especially in the presence of severe phlogosis, which occurs in chronic pancreatitis, in particular during relapse; and (3) irrespective of the tissue origin of urinary PLA2, its increased excretion may be accounted for in part by its increased circulating levels. It is, however, more likely the consequence of a renal tubular dysfunction, which is sometimes found in patients with pancreatic diseases.

Primary sclerosing cholangitis is a rare disease of unknown etiology. Sclerosis of the bile ducts may actually be the final result of multiple factors such as autoimmune, bacterial, congenital, drug, or viral injury. The most commonly associated diseases are ulcerative colitis and chronic pancreatitis. Except in the earliest stages of the disease, liver histologic findings are not specific. Most patients present with jaundice, pain, and pruritus, although an increasing number of asymptomatic patients with inflammatory bowel disease and abnormal liver function are being identified. Cholangiography is key to the diagnosis and is usually pathognomonic except in the unusual case where primary sclerosing cholangitis is confused with cholangiocarcinoma. Many forms of medical therapy have been tried, including antibiotics, azathioprine, cholestyramine, colchicine, cyclosporine, D-penicillamine, steroids, and ursodeoxycholic acid. To date, none of these medications has been proved to alter the course of this disease. Recent reports of ursodeoxycholic acid trials have been encouraging, but long-term results of ongoing randomized trials have yet to be published. In recent years, balloon dilatation of biliary strictures has been accomplished via endoscopic and percutaneous transhepatic approaches. However, in patients with primary sclerosing cholangitis, these nonoperative manipulations must be done repeatedly, may entail multiple general anesthetics, and are difficult to perform. We believe that a direct surgical approach to the biliary tree with long-term transhepatic stenting is indicated in selected patients with severe hilar or extrahepatic stricturing, persistent jaundice or recurrent cholangitis, and no evidence of cirrhosis. Hepatic transplantation should be reserved for patients with primary sclerosing cholangitis who have well-established cirrhosis and have not responded to other therapeutic measures.

Tumor-associated trypsin inhibitor (TATI) is a 6 K dalton protease inhibitor, that was isolated from urine of a patient with ovarian cancer. In our experience, mean serum level of TATI in healthy subjects (n. 120), is 13 micrograms/l (range 5.1-42 micrograms/l). The cut-off point is established in 32 micrograms/l (mean +/- 3 SD). We have examined 357 patients with gastrointestinal diseases: 98 gastric cancer, 50 colon cancers, 52 pancreatic cancers, 32 chronic pancreatitis, 38 IBD, 28 colon polyps, 40 gastric ulcers and 25 non-neoplastic biliary tree diseases. TATI may be a good tumor marker only in gastric cancer. Elevated levels of TATI also occur in obstructive hepatobiliary disease and active pancreatitis or IBD.

Previous studies have shown that sera from patients with pancreatic cancer often contain a mucus glycoprotein that expresses the oncofetal antigen galactose 1-3, N-acetyl galactosamine, which is the T blood group antigen and the binding site for the lectin peanut agglutinin (PNA). An enzyme-linked lectin assay has been developed to quantify PNA-binding glycoproteins in serum and has been evaluated as a serological test for pancreatic cancer. Sera were studied from 53 patients with pancreatic cancer and 154 controls, including benign obstructive jaundice, acute and chronic pancreatitis, chronic liver disease and inflammatory bowel disease. The enzyme-linked peanut lectin assay proved highly reproducible and has 77% sensitivity and 83% specificity for pancreatic cancer, results that are very similar to those achieved in the same sera by CA19-9 radioimmunoassay (75% sensitivity, 82% specificity with the upper limit of normal set at 37 u ml-1). CEA assay proved less useful (60% sensitivity, 47% specificity). In this study better results were obtained if an upper limit of normal of 50 u ml-1 was used for CA19-9 (75% sensitivity, 92% specificity). Combination of CA19-9 assay with the upper limit set at 50 u ml-1 and the peanut lectin assay improved the sensitivity to 85% with only a slight fall in specificity (85%). These results compare well with published results for ultrasound and CT scanning.

PSC is an unusual disease of unknown etiology. In fact, sclerosis of the bile ducts may be the result of multiple factors, including autoimmune, bacterial, congenital, drug, or viral agents. The most commonly associated diseases are ulcerative colitis and chronic pancreatitis. Except for the earliest stages of the disease, liver histology is not specific. Most patients present with jaundice, pain, and pruritus, although an increasing number of asymptomatic patients with inflammatory bowel disease and abnormal liver function are being diagnosed. Cholangiography is the key to the diagnosis and is usually pathognomonic except in the unusual case where PSC is confused with cholangiocarcinoma. Multiple forms of medical therapy have been tried, including steroids, azothiaprine, D-penicillamine, colchicine, cholestyramine, and antibiotics. To date, however, none of these medications has altered the course of this disease. In recent years, balloon dilation of biliary strictures has been accomplished via endoscopic and percutaneous transhepatic approaches. However, in patients with PSC these nonoperative manipulations must be done repeatedly, may require multiple general anesthetics, and are difficult to perform. A direct surgical approach to the biliary tree with prolonged transhepatic stenting is indicated in patients with severe hilar or extrahepatic stricturing, persistent jaundice and/or recurrent cholangitis, and no evidence of cirrhosis. Hepatic transplantation should be reserved for patients with PSC who have well-established cirrhosis and in whom other therapeutic options have failed.

Six patients with idiopathic chronic pancreatitis are described in whom a pancreatogram showed an unusual morphology, being irregularly narrowed throughout. This "shrunken" appearance differs from the classic irregular dilatation usually seen in chronic pancreatitis. Two of the patients had inflammatory bowel disease, none had a history of alcoholism and only one had gallstones.

Plasma retinol was determined by reverse-phase high-performance liquid chromatography in healthy subjects and patients with digestive diseases. The plasma retinol in the healthy control was independent of age (80.5 +/- 17.16 micrograms/dl). On the other hand, the amount of retinol in patient groups was lower than in the healthy control group. It was 30.96 +/- 7.16 micrograms/dl in patients with liver cancer, 38.02 +/- 11.63 micrograms/dl in those with chronic pancreatitis and pancreatic cancer, 45.36 +/- 12.63 micrograms/dl in a patient group with inflammatory bowel disease, 66.25 +/- 7.27 micrograms/dl in the patients of early gastric cancer, and 66.44 +/- 10.10 micrograms/dl in the group with biliary stone. These results and many biological aspects of retinol in human made it clear that, the special attention should be paid to the fluctuation of plasma retinol amount. This was considered to play an important role in causing complications associated with digestive diseases.

Class Alpha glutathione S-transferases (GST-Alpha) are found in high concentrations in human liver. Increased plasma concentrations of GSTA1-1, the most abundant isoform of GST-Alpha, are a very sensitive marker for hepatocellular leakage. A sandwich-type ELISA was developed, based on a monoclonal antibody specific for human GSTA1-1 and a polyclonal rabbit anti-human GST-Alpha antiserum. The assay is specific for human GSTA1-1, and has a detection limit of 0.04 micrograms/L. The distribution of plasma GSTA1-1 concentrations in 350 blood donors was nearly normalized by logarithmic transformation and an upper normal reference concentration of 5.9 micrograms/L was calculated. Men had significantly higher plasma GSTA1-1 concentrations than women (P <0.0001). In women, but not in men, a significant increase was noted with age (P <0.05). In patients with inflammatory bowel disease (n= 210), gastrointestinal tumors (n= 70), irritable bowel disease (n= 36), or chronic pancreatitis (n= 12), plasma GSTA1-1 concentrations were similar to those of controls. In contrast, plasma GSTA1-1 concentrations were increased to a similar extent as alanine aminotransferase activities in patients with liver disorders (n= 37).
