The therapeutic effects of loxiglumide on human acute pancreatitis was investigated in 104 Japanese institutes from October 1992 to March 1994. Acute pancreatitis was diagnosed by the Japanese Criteria of Acute Pancreatitis. Soon after the diagnosis was made, one of three doses of loxiglumide (100, 300 and 500 mg/day) were injected intravenously twice a day for 14 days. The efficacy of the treatment was evaluated by clinical signs, physical signs, and biochemical findings. 189 patients were included in this trial. The clinical signs, such as abdominal pain, disappeared in 20% of the patients on the 1st day after treatment, and the rate of improvements increased thereafter. Physical signs also improved. Serum amylase levels returned to normal within 3 days after treatment, and serum lipase showed almost the same changes as serum amylase levels, but serum lipase levels in the high-dose group (500 mg/day) returned to normal more quickly compared with the other two doses. It is concluded that the cholecystokinin A receptor antagonist, loxiglumide, may become a useful drug in the treatment of acute pancreatitis in man, although more detailed investigations are needed.

Despite the uncommon clinical diagnosis, cats frequently suffer from disorders of the exocrine pancreas. Pancreatitis is the most common feline exocrine pancreatic disorder. Pancreatitis can be acute or chronic and mild or severe. The etiology of most cases of feline pancreatitis is idiopathic. Some cases have been associated with severe abdominal trauma, infectious diseases, cholangiohepatitis, and organophosphate and other drug intoxication. The clinical presentation of cats with pancreatitis is nonspecific. Vomiting and signs of abdominal pain, which are the clinical signs most commonly observed in humans and dogs with pancreatitis, are only uncommonly observed in cats with pancreatitis. Routine laboratory findings are also nonspecific. Abdominal ultrasonography is a valuable diagnostic tool in feline patients with pancreatitis. Serum activities of lipase and amylase are rarely increased in cats with pancreatitis; however, these cats often have elevated serum fTLI concentrations. The goals of management are removal of the inciting cause, provision of supportive and symptomatic therapy, and careful monitoring for and aggressive treatment of systemic complications. Exocrine pancreatic insufficiency is a syndrome caused by insufficient synthesis of pancreatic digestive enzymes by the exocrine portion of the pancrease. The clinical signs most commonly reported are weight loss, loose and voluminous stools, and greasy soiling of the hair coat. Serum fTLI is subnormal in affected cats. Treatment of cats with EPI consists of enzyme supplementation with powdered pancreatic extracts or raw beef pancreas. Many cats with EPI have concurrent small intestinal disease. Most cats with EPI also have severely decreased serum cobalamin concentrations and may require parenteral cobalamin supplementation. Pancreatic adenocarcinoma is the most common neoplastic condition of the exocrine pancreas in the cat. At the time of diagnosis, the tumor has already metastasized in most cases, and the prognosis is poor. Pancreatic pseudocyst, pancreatic abscess, pancreatic parasites, pancreatic bladder, and nodular hyperplasia are other exocrine pancreatic disorders, that are less commonly seen in cats.

We compared the morphologic findings of the common bile duct by ultrasonography and endoscopic retrograde cholangiopancreatography in patients with biliary acute pancreatitis. Forty-five patients were studied. The diagnosis of acute pancreatitis was based on the presence of characteristic abdominal pain associated with an elevation of serum amylase and lipase concentrations. All patients underwent ultrasonography and subsequently urgent endoscopic retrograde cholangiopancreatography and eventually endoscopic sphincterotomy. Ultrasonography showed gallstones in 33 patients and sludge of the gallbladder in seven patients. In the common bile duct, lithiasis was found in two patients and sludge in 25. Endoscopic retrograde cholangiopancreatography showed choledocolithiasis in eight patients and sludge of the common bile duct in 32. In 27 cases (60%) concordance occurred between ultrasonographic and endoscopic retrograde cholangiopancreatographic detection of lithiasis or sludge of the common bile duct. The average diameter of the common bile duct determined by sonography was significantly smaller (P < 0.001) than that obtained by endoscopic retrograde cholangiopancreatography. The evaluation of this parameter indicated that a good correlation existed between the values obtained with the two techniques (r(s) = 0.765, P < 0.001). Both ultrasonography and endoscopic retrograde cholangiopancreatography can provide reliable measurements of the common bile duct diameter. Ultrasonography is the technique of choice in the initial investigation of patients with biliary acute pancreatitis.

Diabetic ketoacidosis (DKA) is frequently associated with pancreatic enzyme abnormalities. In order to determine the main factors that lead to this increase, serum total amylase (TA), pancreatic amylase (PA), lipase (L) and leukocyte elastase (LE), an early predictor of acute pancreatitis, were measured in four groups of patients on admission. Group 1 consisted of 52 patients with DKA (age: 41.9 +/- 19.2 years; blood glucose (Glc): 27.4 +/- 11.5 mmol/L; pH: 7.20 +/- 0.16; plasma bicarbonate: 10.5 +/- 6.2 mmol/L; blood urea nitrogen (BUN): 0.60 +/- 0.44 g/L; HbA(1C): 12.5% +/- 2.8%). Group 2 consisted of 90 patients with poorly controlled non-ketotic diabetes (age: 53.4 +/- 16.0; Glc: 14.3 +/- 0.6; HCO(3)(-): 26.6 +/- 3.2; BUN: 0.38 +/- 0.20; HbA(1C): 11.3 +/- 2.1). Group 3 consisted of 22 patients with well-controlled diabetes (age: 53.7 +/- 12.8; Glc: 10. 1 +/- 5.2; HCO(3)(-): 27.4 +/- 3.8; BUN: 0.36 +/- 0.19; HbA(1C): 6.8 +/- 0.8). Group 4 (controls) comprised 27 non-diabetic patients (age: 46.0 +/- 15.0; Glc: 4.9 +/- 0.5; HCO(3)(-): 28.4 +/- 2.5; BUN: 0.30 +/- 0.16; HbA(1C): 5.2 +/- 0.7) (means +/- SD). Increased enzyme activities were more frequent in group 1 (TA: 30.7; PA: 27.0; L: 36.5; LE: 73%) than in groups 2 (TA: 8.9; PA: 7.1; L: 8.9; LE: 45. 5%), 3 (TA: 13.6; PA: 9.0; L: 18.1; LE: 31.8%) and 4 (TA: 7.0; PA: 3. 0; L: 0.0; LE: 29.6%). Mean serum enzyme activities were significantly different in the 4 groups (ANOVA, P < 0.01) and were higher in group 1 than in groups 2, 3 and 4 (Student's t-test; group 1 vs 2 or 3 or 4: P < 0.001). In groups 1 + 2 + 3 + 4 (all patients), the four enzymes correlated with one another and also with Glc, BUN and HCO(3)(-) (P < 0.001). In group 1, TA correlated negatively with HCO(3)(-) (P < 0.001) and pH (P < 0.05); PA and L correlated positively with Glc and BUN (P < 0.01) and negatively with HCO(3)(-) (respectively, p < 0.01 and 0.05). PA correlated positively with pH (P < 0.01); LE correlated with Glc (P < 0.05) and BUN (P < 0.01). In conclusion, this study suggests that the serum levels of pancreatic enzymes increase with the degree of diabetic disequilibrium, and mainly correlate with metabolic factors such as hyperglycaemia, dehydration and acidosis. Increased pancreatic enzyme activities in patients with DKA, even in combination with abdominal pain, should not be diagnosed as acute pancreatitis; this could be important, particularly for younger clinicians.

Gastrointestinal bleeding and increased intestinal permeability have been observed in marathon runners. We sought to determine if L-arginine would be useful for prevention of these complications. Twenty-three runners were randomized to receive L-arginine (A) or glycine (placebo) (G), 10 grams 3 times daily for 14 days prior to the 1997 Houston-Methodist Marathon. Serum, stool hemoccults and lactulose:mannitol permeabilities were obtained at baseline, immediately after completion of the marathon and approximately 48 hours later. Runners rated their symptoms of nausea and vomiting, belching and indigestion, abdominal pain and bloating, diarrhea, and extremity pain on a 1-5 scale of increasing severity. The L:M was unchanged in either group during the three collections. Occult bleeding occurred in 8%/20% in A and G groups, respectively, p = NS) immediately post-marathon. No runners had occult bleeding 48 hours post-race. Gastrointestinal symptom scores were minimal to nonexistent. Extremity pain scores were similar for groups A and G (2.1+/-1.4 and 2.8+/-1.6, respectively, (p = NS). Fluid intake was similar between both groups (1875+/-1547 vs. 1506+/-970 ml, p = NS). Serum amylase was normal at baseline and remained virtually unchanged. Serum lipase was normal at baseline and immediately post-race in both groups, but increased at 48 hours post-race (82.2+/-34.3 to 121.5+/-53.3 mg/dl [A], p = 0.02 and 114.3+/-55.7 to 181.9+/-162.2 mg/dl [G], p = 0.09). CPK increased significantly and similarly in both groups immediately post-race, and even more dramatically 48 hours post-race (130.3+/-130.8 to 738.8+/-902.9, p = 0.007 to 1966.5+/-3.166.0 mg/dl [A] and 140.9+/-77.9 to 863.0+/-772.3, p = 0.003 to 5619+/-10636.8mg/dl [G]). Modest post-race decreases were seen in most serum amino acids in both groups. Finish times were longer than predicted (23+/-21 and 9+/-7 min for A and G groups, respectively, p = 0.049). Our study failed to show a clear benefit of arginine supplementation for the prevention of intestinal ischemia/reperfusion injury associated with endurance running, but either a detrimental affect on performance with arginine, or enhanced performance with glycine. Skeletal muscle injury was unaffected by arginine or glycine supplementation. The delayed increase in serum lipase suggests mild pancreatic injury, affected by either arginine or glycine supplementation.

Recently an ELISA using specific antibodies to detect elastase-1 in serum has become available. Earlier studies using a radioimmunoassay reported a prolonged elevation of serum elastase as compared to other pancreatic enzymes in acute pancreatitis. The aim of the present study was to compare the changes of serum levels of ELISA-elastase-1, lipase and amylase in acute pancreatic damage following ERCP. Blood samples were prospectively collected at five time points before and after the endoscopic procedures in 212 patients. Samples were analyzed for pancreatic serum enzymes, acute phase proteins and routine parameters. A pain score was used for clinical evaluation. Relevant post ERCP pancreatic damage was defined as CRP elevation from < 10 mg/l to > 10 mg/l in the presence of persistent abdominal pain without laboratory evidence of cholangitis and without clinical or laboratory signs of pancreatitis before the endoscopic procedures. Elastase-1 time course paralleled the courses of lipase and amylase peeking at six hrs. There was no prolonged elevation of elastase-1. Ten out of 204 patients (4.9%) were found to have relevant pancreatic damage. Depending on the cut off point used, sensitivity/specificity were as follows: lipase 80-100%/30.9-71.6%; amylase 70-90%/44.3-88.7%; elastase-1 60-90%/64.9-81.4%. In conclusion ELISA-elastase-1 is a marker of acute pancreatic damage similar to lipase and amylase. Although elastase-1 may show a better specificity than the other enzymes, this seems to be a matter of definition of the normal range. The determination of serum ELISA-elastase-1 does not provide additional information in acute pancreatic damage as compared to a combination of lipase and amylase.

Hypertriglyceridaemia is thought to be the aetiology in 3% of patients with acute pancreatitis, often associated with poorly controlled diabetes mellitus or chronic alcohol abuse. However, in patients with non-biliary pancreatitis, chylomicronaemia is an underrated cause of acute pancreatitis. The activity of lipoprotein lipase (LPL) is crucial in removing triglycerides from the plasma; LPL gene mutations combined with secondary alterations in plasma lipoproteins, such as occur in pregnancy, diabetes mellitus, and alcohol abuse can cause severe hypertriglyceridaemia and pancreatitis. Heparin and insulin stimulate LPL activity. During a 12 months' period we consecutively screened all patients with the diagnosis of acute non-biliary pancreatitis for hypertriglyceridaemia, to evaluate the prevalence of hypertriglyceridaemia-induced pancreatitis and to assess the outcome under standardised treatment with intravenous heparin and insulin. Hypertriglyceridaemia-induced pancreatitis was diagnosed in 5 out of 46 patients (11%) with acute pancreatitis. In 2 patients hypertriglyceridaemia was associated with diabetes mellitus, in one patient with pregnancy and in another with chronic alcohol abuse. Four patients had to be referred to the intensive care unit. Plasma concentrations of triglycerides were (median +/- range) 43 mmol/l (14.7 to 80.4); pancreas amylase was 574 U/l (155 to 1606), and lipase was 1003 U/l (330 to 3010). All patients had oedematous pancreatitis demonstrated by CT scan. Treatment with i.v. heparin and i.v. insulin decreased trigylceride levels to less than 10 mmol/l within 2.8 days (1 to 6), the amylase and lipase levels returned to normal after 3 and 4 days respectively, and the abdominal pain was resolved. Hypertriglyceridaemia is a common and under-diagnosed etiology of acute non-biliary pancreatitis. Intravenous heparin and insulin is safe and effective in the treatment of hypertriglyceridaemia-induced pancreatitis. Low fat diet, supplements of (n-3) fatty acids ("fish oil") and fibrates are recommended for long-term maintenance therapy.

Chronic pancreatitis is characterized by progressive and irreversible loss of pancreatic exocrine and endocrine function. In the majority of cases, particularly in Western populations, the disease is associated with alcohol abuse. The major complications of chronic pancreatitis include abdominal pain, malabsorption, and diabetes. Of these, pain is the most difficult to treat and is therefore the most frustrating symptom for both the patient and the physician. While analgesics form the cornerstone of pain therapy, a number of other treatment modalities (inhibition of pancreatic secretion, antioxidants, and surgery) have also been described. Unfortunately, the efficacy of these modalities is difficult to assess, principally because of the lack of properly controlled clinical trials. Replacement of pancreatic enzymes (particularly lipase) in the gut is the mainstay of treatment for malabsorption; the recent discovery of a bacterial lipase (with high lipolytic activity and resistance to degradation in gastric and duodenal juice) represents an important advance that may significantly increase the efficacy of enzyme replacement therapy by replacing the easily degradable porcine lipase found in existing enzyme preparations. Diabetes secondary to chronic pancreatitis is difficult to control and its course is often complicated by hypoglycaemic attacks. Therefore, it is essential that caution is exercised when treating this condition with insulin. This paper reviews recent research and prevailing concepts regarding the three major complications of chronic pancreatitis noted above. A comprehensive discussion of current opinion on clinical issues relating to the other known complications of chronic pancreatitis such as pseudocysts, venous thromboses, biliary and duodenal obstruction, biliary cirrhosis, and pancreatic cancer is also presented.

A 51 year old man presents with a short history of acute onset severe upper abdominal pain. It is predominantly epigastric, radiating to the back. The pain is exacerbated by lying flat, improves on sitting upright, and is associated with nausea and vomiting. Both serum amylase and serum lipase levels are elevated. A CT scan of the abdomen was performed (Figures 1, 2).

Macroamylasemia is a condition of persistent, elevated serum amylase activity with no apparent clinical symptoms of a pancreatic disorder. In Korea, however, no such case has been reported to date. We report a case of a 17-year-old female diagnosed with macroamylasemia and acute appendicitis. One day earlier, she developed epigastric and right lower quadrant abdominal pain. She was characterized by high level of serum amylase, but normal lipase. Amylase isoenzyme analysis demonstrated increased fraction of salivary type and follow-up amylase level was persistently increased. Immunofixation disclosed the macroamylase binding with an immunoglobulin, consisting of IgA and kappa chain. The patient was treated by appendectomy, and the abdominal pain subsided.
