We reported two cases of acute recurrent pancreatitis lasting for 8 and 10 years, respectively, and characterized by acute abdominal pain associated with an increased serum level of pancreatic enzymes and in one case transient enlargement of the pancreas on sonography and CT scan. Exocrine and endocrine pancreatic function remained normal. Pain attacks were associated with headache or typical migraine, myalgia, pruritus, and diarrhea. In one case only, the IgE serum level was increased. In both cases, the symptoms were reproduced in the 2 h following the consumption of some particular food and cured for years by the suppression of this food and the use of cromoglycate, but recurred 1 month to 3 years after this treatment was stopped, to be again healed by the same treatment. We suggest that these cases are due to food allergy and that food allergy could be a rare cause of acute recurrent pancreatitis. Responsible foods were beef (twice), milk, potato, fish, and eggs, which is in agreement with the frequency of food allergens in southwestern Europe.

In 134 consecutive patients with acute abdominal pain, we evaluated the clinical role of a new rapid test for serum lipase based on latex agglutination. The results were compared with those obtained with a widely used lipase immunoassay as well as with serum amylase and pancreatic isoamylase measurements. Fifty-five healthy subjects were studied as controls. In 174 cases (121 patients and 53 controls) the results of the two lipase assays were in agreement. A positive lipase latex test was found in 10 of 12 patients with acute pancreatitis, in eight of 24 patients with other pancreatic diseases, and in 14 of 98 with nonpancreatic diseases. The sensitivity and specificity of this test were similar to those of the other pancreatic enzyme assays performed. The results indicate that the lipase latex agglutination test is useful for emergency screening for acute pancreatitis in patients with acute abdominal pain.

The clinical value of amylase and lipase measurement for the diagnosis of acute pancreatitis was evaluated in 253 patients presenting with acute abdominal pain. Acute pancreatitis was detected in 32 patients by computed tomography or ultrasound. In the serum samples collected on days 0-1 after the onset of symptoms, lipase was elevated in 100% and amylase in 95%. A 95% sensitivity/specificity was reached at a lipase cutoff near twofold above normal. The receiver-operating characteristics (ROC) showed similar curves for both enzymes, lipase being slightly superior to amylase. The ROC curves from days 2-3 demonstrated a much lower sensitivity/specificity of both enzymes. Lipase, however, was notably superior to amylase: at a sensitivity of 85% the specificity of lipase (amylase) was 82% (68%). In samples from days 4-5 the accuracy of the enzyme assays was even worse; at a sensitivity of 60% the specificity did not increase above 70%. The diagnostic value of simultaneous measurement of amylase and lipase was tested at different cutoffs in two groups: the OR group, in which one of the two parameters had to be elevated, and the AND group, in which both parameters had to be above normal. Combination of both parameters mainly improved the specificity of the assay (from 91 to 98% on days 2-3 and from 93 to 97% on day 4-5) but only when, in the OR group, twofold elevated amylase was combined with lipase. We conclude that the simultaneous determination of serum lipase and amylase marginally improved the diagnosis of acute pancreatitis in patients with acute abdominal pain, however, the sensitivity of the assay with samples collected 4-5 days after onset of the disease remained low.
