The patients seen at the medical clinic of a community hospital over 6 years included 291 with diseases of the pancreas, 52 of whom had carcinoma of the pancreas. Their signs and symptoms are listed. The triad of weight loss, icterus, and abdominal pain was the commonest symptom cluster. In one third of the cases the serum lipase was raised though the blood level of amylase was normal. Laparoscopy led to exploratory laparotomy in 94 percent of cases, which was performed an average of 14 days later. The future will show whether ERCP (+cytology) and CEA will improve the possibility of early diagnosis.

A 36-year-old woman was admitted to hospital with a first attack of acute intermittent porphyria. At the same time increased serum levels of amylase and lipase as well as an increased amylase clearance to creatinine clearance ratio were observed, permitting the diagnosis of acute pancreatitis. The etiology of the latter could not be determined. In addition, elevation of indirect bilirubin without evidence of hemolysis was observed Gilbert's syndrome was suspected. 40 weeks after the first episode, a second attack of identical abdominal pain was noted, with elevation of pancreatic enzymes in the serum. There is evidence that acute intermittent porphyria and acute relapsing pancreatitis may have some etiological connection in this patient.

Ten adolescent and young adults with cystic fibrosis (CF) have had well-documented recurrent attacks of acute pancreatitis. The diagnosis of CF in each patient was delayed because they did not have pancreatic insufficiency. The diagnosis of CF was documented by the typical pulmonary involvement and elevated sweat sodium and chloride levels in all cases and a positive family history in six of the ten patients. Two patients were diagnosed as having acute pancreatitis before the diagnosis of CF was made, thus indicating that acute pancreatitis may be the presenting complaint in the young adult with CF. The diagnosis of acute pancreatitis was based on the presence of severe abdominal pain, usually with vomiting, tenderness in the mid-epigastrium, elevated serum and urinary amylase and serum lipase. Attacks were precipitated by fatty meals, alcohol ingestion; postcholecystectomy and tetracycline administration. In some patients no precipitating event could be elicited. Intravenous secretin-pancreozymin stimulation tests revealed a diminished bicarbonate secretion with little effect on the secretion of the zymogen enzymes. A mild attack of pancreatitis occurred after secretin-pancreozymin stimulation. The endocrine pancreatic function tested in four patients was normal as revealed by the glucose tolerance tests and determinations of serum insulin, growth hormone and free fatty acid. Transduodenal pancreatograms were performed in three patients; one showed a normal pancreatic duct, one showed duct obstruction and in the third patient a beady type of narrowing was found. The selenomethionine Se 75 uptake of the pancreas was noted only in the head of the pancreas. This suggests that loss of function occurs initially to a greater extent in the tail and body of the pancreas. Three patients died and showed characteristic lesions of CF.

Twelve patients with prior episodes of alcoholic pancreatitis and hyperlipemia were admitted to a metabolic ward during a quiescent period. By lipid feeding (316 to 894 Gm. per day), significant hypertriglyceridemia (greater than 600 mg. per 100 ml.) was induced in 11 of the 12 patients. Seven of the 11 patients with hypertriglyceridemia developed abdominal pain similar to but not as severe as that experienced during prior attacks of pancreatitis. Four of the seven patients with abdominal pain developed serum amylase elevations, and, of the remaining three, one had a serum lipase elevation and one a urinary amylase elevation. Alcohol ingestion is known to increase serum triglyceride levels in many individuals. A prior study demonstrated that 41 percent of the patients presenting to our hospital with alcoholic pancreatitis had serum triglyceride elevations. The data from the present study suggest that increased serum triglycerides act as an important intermediary in the pathogenesis of acute pancreatitis in some alcoholic patients.

Eight-four patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) were randomized to receive 100 micrograms of octreotide intravenously immediately prior to ERCP, and 100 micrograms subcutaneously 45 min after the initial dose, or placebo. Amylase, lipase, and glucose were measured and clinical assessment was performed before, and 2 and 24 h after, ERCP. We define clinical pancreatitis as the combination of elevated amylase or lipase with abdominal pain and tenderness. Interim analysis in 84 patients revealed an 11% incidence of clinical pancreatitis in the control group and 35% in the treatment group (p < 0.01). There were no differences in either group with respect to sphincterotomy, gender, age, duration of ERCP, number of cannulations of the pancreatic duct, degree of duct injection, or the volume of contrast injected. Analysis of group differences stratified by sphincterotomy revealed the following: 1) In patients who did not undergo a sphincterotomy, there was a significantly higher rate of pancreatitis in the treatment group [10/17 (59%) versus 1/17 (6%) RR 10.0 (95% CI 1.4-69.8)]. 2) Sphincterotomy reduced the rate of pancreatitis in patients who received octreotide from 10/17 (59% no sphincterotomy), to 3/20 (15% sphincterotomy) (p = 0.01), which equals the rate in patients who received placebo and underwent sphincterotomy [4/25 (16%)]. 3) Although the incidence of pancreatitis was higher in the treatment group, octreotide may reduce the severity of pancreatitis measured by the number of days NPO (Wilcoxon rank sum, p = 0.02), length of stay after ERCP (p = 0.13), the number of days of pain (p = 0.11), and the degree of amylase elevation (p = 0.04). We conclude that: 1) Octreotide appears to increase the incidence of pancreatitis when given prophylactically for diagnostic ERCP. 2) Although pancreatitis was more common in the octreotide group, it was less severe than the placebo group. 3) Sphincterotomy may afford protection against pancreatitis in patients who received octreotide. 4) We cannot recommend the use of prophylactic octreotide during diagnostic or therapeutic ERCP.

To determine whether the lipase:amylase ratio differentiates alcoholic from nonalcoholic pancreatitis, we conducted a retrospective review of charts with the diagnosis of acute pancreatitis at the George Washington University Medical Center between January 1988 and July 1990. A total of 446 charts were reviewed. For a patient to be included in the subsequent analysis, the following criteria were met: 1) the patient had typical symptoms of pancreatitis, 2) serum amylase and lipase were analyzed on admission, and 3) a computerized tomographic (CT) scan or ultrasound of the abdomen was obtained within 72 h of admission. Forty-seven charts satisfied the requirements for inclusion in the study. Data collected from the charts included history of alcohol consumption, age, sex, race, admission serum amylase and serum lipase (from this the amylase:lipase ratio was calculated), peak serum amylase and serum lipase, and number of days of abdominal pain before admission. Patients with alcoholic pancreatitis had significantly lower serum amylase levels and significantly higher lipase:amylase ratios than those with nonalcoholic pancreatitis (p < 0.01). There was no difference in the serum lipase between the groups. The higher the lipase:amylase ratio, the greater the specificity of alcohol as the etiology of acute pancreatitis. Only patients with alcoholic acute pancreatitis had lipase:amylase ratios > 5.0 (sensitivity 31%, specificity 100%). Our data point to the clinical utility of the lipase:amylase ratio in differentiating alcoholic from nonalcoholic acute pancreatitis. Prospective studies will be needed to confirm the clinical utility of this ratio.

Because pancreatitis has been reported frequently in adults with human immunodeficiency virus infection, we sought to determine the incidence of pancreatitis in children with acquired immunodeficiency syndrome by reviewing all records of children with AIDS, their serum amylase and lipase levels, and the factors associated with pancreatitis through a case-control analysis. During a 6-year period pancreatitis developed in 9 (17%) of 53 pediatric patients with AIDS. Six children had vertical transmission of infection and three patients had acquired HIV infection through contaminated blood products. Pancreatitis developed at a median age of 5.2 years (range 1.2 to 20 years). All patients had vomiting and abdominal pain. When the patients were first seen, lipase values were elevated more than amylase values (p = 0.028). Amylase and lipase levels declined at comparable rates. In the case-control analysis, pentamidine isethionate was significantly associated with pancreatitis (p = 0.02); the risk was greater in patients who received pentamidine isethionate and had absolute CD4 T-lymphocyte counts less than 100 cells/mm3 (p = 0.001). Infections associated with the onset of pancreatitis included cytomegalovirus (4), Cryptosporidium (1), Pneumocystis carinii pneumonia (3), and Mycobacterium avium intracellulare (1). Coinfection with cytomegalovirus was associated with a protracted course in four children. Ultrasonographic examination demonstrated biliary ductal dilatation 6 months after the onset of pancreatitis in one child. Seven children have died at a mean of 8 months after the initial onset of pancreatitis; the one living child has survived 5 months from the onset of pancreatitis. We conclude that pancreatitis is common in pediatric patients with AIDS and may be related to pentamidine isethionate exposure, especially when absolute CD4 T-lymphocyte counts are less than 100 cells/mm3. Serum amylase levels do not always accurately predict the onset of pancreatitis; serum lipase levels should be measured in children with symptoms. The onset of pancreatitis in an HIV-infected child is a poor prognostic indicator.

The diagnostic capacity of a semiquantitative latex test for lipase measurement was compared with the measurement of other pancreatic enzymes in 100 consecutive patients admitted to a general hospital for recent onset of severe abdominal pain. Positive results of the test were found in two patients with acute pancreatitis, and in one out of three chronic pancreatitis relapses. The test yielded false-positive results only in two patients who had no apparent pancreatic involvement. A marginal increase in other pancreatic enzymes was found in a few patients with acute biliary or appendicular problems. In conclusion, the lipase latex test can be suggested in an emergency setting as a quick and reliable alternative to serum amylase to rule out a diagnosis of acute pancreatitis.

This study evaluates the effect of the long acting somatostatin analogue octreotide on biochemical and clinical parameters of endoscopic retrograde cholangiopancreatography (ERCP) induced pancreatitis. Altogether 245 patients were randomised to receive either octreotide or isotonic saline. Octreotide (100 micrograms) was administered intravenously five minutes before ERCP and subcutaneously 45 minutes after ERCP. There were no significant differences in the median serum amylase and lipase activities at baseline, eight, and 24 hours after ERCP. Five patients (2%) developed clinical pancreatitis--three in the octreotide and two in the placebo groups. Excluding patients who developed pancreatitis, 43 (18%) developed abdominal pain after ERCP--21 in the octreotide and 23 in the placebo groups. There were no significant differences in the median serum amylase and lipase values between the treatment groups. None of the 52 patients who had therapeutic interventions developed pancreatitis. This study suggests that octreotide may not protect against ERCP induced pancreatitis.

We report three patients with diabetic ketoacidosis (DKA) who presented with striking elevations of serum lipase levels and less striking elevations of amylase and trypsinogen. All three had nausea and vomiting, but none had objective evidence of abdominal pain, and computed tomography scans of the pancreas were unremarkable. These cases suggest the association of asymptomatic enzyme elevations with DKA. We review the literature on this subject.
