To study the role of the vasodilatory, antiaggregatory prostacyclin (PGI2) and its endogenous antagonist thromboxane A2 (TxA2) in acute pancreatitis, we measured serum thromboxane B2 (TxB2, which indicates platelet TxA2 production) and plasma 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha, which indicates systemic PGI2 production) from sequential blood samples in trypsin and taurocholate induced acute canine hemorrhagic pancreatitis (AHP). In addition the effect of a prostaglandin synthesis inhibitor, ibuprofen, was studied and systemic (MAP) and pulmonary artery pressure (MPAP) were recorded for 4.5 hr. The animals were divided into a sham-operated group, an AHP group, an ibuprofen prophylaxis group, and an ibuprofen therapy group. In the sham group the parameters remained stable throughout the experiment. In the AHP group MAP decreased steadily and 6-keto-PGF1 alpha rose significantly from 80.0 +/- 7.8 to 956.0 +/- 287.0 pg/ml (P less than 0.001), whereas serum TxB2 and MPAP remained unchanged. Ibuprofen prophylaxis eliminated the initial fall in MAP and the rise of 6-keto-PGF1 alpha. Ibuprofen therapy normalized the initially decreased MAP and depressed the level of 6-keto-PGF1 alpha. We conclude that PGI2 may at least partly mediate the initial hypotension in canine AHP, whereas platelet TxA2 production obviously has a negligible role in the development of hemodynamic changes in AHP.

Drug-induced acute pancreatitis (DIP) is uncommon and may account for 2%-5% of cases, although the incidence may be increasing nowadays. DIP has been documented for more than 160 drugs in the literature. The most common nonsteroidal anti-inflammatory drugs (NSAIDs) that have been reported to cause pancreatitis are sulindac and salicylates. In this report, we present a case of probable ibuprofen-induced pancreatitis. A 60-year-old white woman presented with the sudden onset of mild acute pancreatitis (AP) 5 hours following the ingestion of 6 tablets of ibuprofen (Advil) 200 mg (equivalent to 20.4 mg/kg). She denied any history of alcohol abuse, tobacco smoking, or any other medication use. She has no history of gallstones, choledocholithiasis, abdominal trauma, or hypertriglyceridemia. Laboratory workup revealed elevated amylase and lipase levels more than 3 times the normal limits with complete resolution within 15 hours. Computed tomography scan of abdomen and pelvis and endoscopic ultrasound of the pancreaticobiliary system were within the normal limits. Ibuprofen-induced mild DIP was the most probable diagnosis. She was discharged on her second day of hospitalization with significant improvement in her symptoms. Physicians need to be aware that DIP may occur in patients taking NSAIDs, including ibuprofen. Therefore, all patients with AP of an unknown etiology should be carefully questioned about the usage of NSAIDs, and all patients with idiopathic AP restarted on their medications should be closely monitored, and the drug must be immediately discontinued if symptoms recur.
