A previously healthy 35-year-old woman was seen at 37 weeks' gestation with a 10-day history of fever, vomiting, diarrhea and malaise. Serum laboratory findings included elevation of serum bilirubin and AST, prolongation of serum prothrombin time and a positive monospot. A tentative diagnosis of acute fatty liver of pregnancy was made, and a healthy male infant was delivered by emergency cesarean section because of fetal distress. Over the subsequent 3 days, acute progressive oliguric renal failure, disseminated intravascular coagulation, hypoglycemia requiring intravenous dextrose infusion and pancreatitis developed; her mental status progressed to stage III encephalopathy. Quantitative computed tomography estimated the liver volume to be 770 cm3. The decision to proceed with orthotopic liver transplantation was made on the basis of progressive clinical deterioration despite aggressive support and because of her small liver size. After transplant, the patient's multisystem failure rapidly reversed. Histopathological examination of the native liver demonstrated predominantly zone 3 microvesicular steatosis with characteristic ultrastructural changes consistent with acute fatty liver of pregnancy. Southern blot analysis for Epstein-Barr virus DNA was negative. We conclude that orthotopic liver transplantation should be considered for the small group of patients with fulminant hepatic failure associated with acute fatty liver of pregnancy who manifest signs of irreversible liver failure despite delivery of the fetus and aggresive supportive care.

Early distinction between acute alcoholic pancreatitis is important, because of possible emergency endoscopic sphincterotomy in case of biliary pancreatitis. The aim of this study was to evaluate the value of L/A ratio in the diagnosis of acute alcoholic pancreatitis. From 1990 to end 1993, 133 patients with acute pancreatitis were reviewed. Inclusion criteria were: 1) abdominal pain, 2) pathological serum amylase or serum lipase on admission or within 24 hours after beginning or abdominal pain, 3) acute pancreatitis at the echography or CT scan within 48 hours after admission. 60 patients met the inclusion criteria (31 alcoholic pancreatitis, 19 biliary pancreatitis and 10 pancreatitis of other causes). L/A ratio was studied in terms of delay from beginning of abdominal pain. There was no statistical difference between alcoholic and biliary pancreatitis at any time of the study, with the exception of admission. AST, ALT and alkaline phosphatase were higher in biliary pancreatitis than in alcoholic pancreatitis. AST and ALT were the best biochemical tests to diagnose biliary pancreatitis. Blamey's criteria can also contribute to diagnose biliary pancreatitis. These biochemical tests are the most helpful if they are collected very soon in the evolution of acute pancreatitis. It is concluded that L/A ratio is not helpful in the diagnosis of alcoholic acute pancreatitis.

In this study we observed the discriminative ability of five commonly measured laboratory tests to distinguish between gallstone- and non-gallstone-associated pancreatitis. We also assessed the ability of the lipase-amylase ratio to discriminate between alcohol- and non-alcohol-induced pancreatitis. One hundred sixty-two patients with acute pancreatitis were included in the study. Group A consisted of patients presenting to our hospital in 1988 and 1989. Group B consisted of patients presenting in 1992. Models developed using group A patients were validated using group B patients. For gallstone pancreatitis, AST (threshold value 80 IU/liter) alone and a three-factor model, AST, ALP and bilirubin (threshold values of 80 IU/liter, 115 IU/liter, and 15 mumol/liter, respectively) were the best predictors, correctly classifying at least 80% of cases in group A and B. A lipase-amylase ratio of two correctly classified only 48% of cases in group A and 54% in group B. We conclude that biochemical models are useful in predicting the presence of gallstone pancreatitis but not alcoholic pancreatitis.

Therapeutic observations suggest that azidothymidine (AZT)-resistant HIV+/AIDS patients are frequently offered AZT/dideoxycytidine (DDC) or dideoxyinosine (DDI) therapy. The latter therapies have been associated with the development of acute pancreatitis. During the initial portion of this study, when patients reported limiting ethanol consumption, an increase in CD4+, a decrease in amylase, and a decrease in lipase was observed in patients on DDI monotherapy. Marinol/marijuana usage was associated with depressed CD4+ counts and elevated amylase levels within the DDI subgroup. The purpose of this study was to follow these patients over 1 year and compare clinical indicators of pancreatitis and HIV progression. After 1 year, the remaining 56 patients were reexamined in the follow-up portion for clinical indicators of HIV disease progression and pancreatoxic/hepatotoxic effects. Those in the AZT group, who remained on this therapy throughout the year, had significantly increased amylase values from 55.3 to 69.3 IU/liter (p < 0.05). In the AZT/DDC group, those who remained on combination therapy throughout the year, 4 of the 5 clinical indicators of disease progression changed. Amylase, ALT, and AST all increased significantly from 55.2 to 77.8 IU/liter (p < 0.01), from 38.0 to 92.3 IU/liter (p < 0.05), and from 55.2 to 97.0 IU/liter (p < 0.05), respectively. Lipase levels decreased significantly (106.0 to 74.6 IU/liter, p < 0.05). The most remarkable changes occurred in the AZT/DDC group (who reduced ethanol consumption), wherein clinical indicators of pancreatitis and liver dysfunction declined, including amylase (65.0 to 20.0 IU/liter, p < 0.05), ALT (350.0 to 100.0 IU/liter, p < 0.01), and AST (240.0 to 95.0 IU/liter, p < 0.01). No significant changes were noted in the DDI or AZT groups. Marinol/marijuana use was associated with declining health status in both the AZT and AZT/DDC groups. In contrast, all clinical indicators of pancreatitis improved in the DDI patients who utilized Marinol/marijuana, including amylase (-34%), lipase (-30.8%), ALT (-21.4%), and AST (-20.1%). This paired follow-up study suggests that HIV+/AIDS patients on antiretroviral therapies should restrict their ethanol consumption. In HIV+/AIDS patients with the lowest CD4+ counts (those on DDI monotherapy), utilization of Marinol/marijuana does not seem to have a deleterious impact.

A six-week placebo-controlled trial of the efficacy and safety of 6 g per day of 4-aminosalicylic acid (4-ASA) was conducted in 30 subjects with mild to moderately severe ulcerative colitis. Subjects were stratified into groups having distal (< 60 cm) or more extensive (> 60 cm) disease. Diarrhea, bleeding, sigmoidoscopic and biopsy appearance, and physician global assessment were scored to judge efficacy. Safety was evaluated by monitoring untoward symptoms and laboratory values. Median percent improvement was significantly greater (P < 0.05) in the 4-ASA > 60-cm group (42.7%) than in the placebo > 60-cm group (21.2%), but 4-ASA was not better than placebo for the < 60-cm group or the total study group. Severe dyspepsia (one subject), abnormal AST (transient in five, persistent in one) and elevated lipase without pancreatitis (six subjects) were noted. Thus 6 g 4-ASA for six weeks was more effective than placebo in mild to moderate ulcerative colitis extending more than 60 cm above the anus, but not in distal disease, and the drug was generally well tolerated.

For a substantial number of patients with acute pancreatitis, no recognizable causes can be identified and such cases are called "idiopathic". With the introduction of duodenal bile collection for microscopic examination, it became possible to detect minor constituents of the bile, such as cholesterol and/or calcium bilirrubinate crystals. The mechanism by which crystals produce pancreatitis seems to be related to migration of aggregate crystals through the papilla, inducing papillary trauma or temporary impaction which can cause a biliopancreatic reflux. We now report a series of 45 patients with acute pancreatitis idiopathic, 120 with gallstones and 22 alcoholic. Of the patients with idiopathic pancreatitis whom we studied by biliary drainages, 22 were found to have abnormal drainages (MC+) (20 cholesterol crystals and 2 calcium bilirrubinate), 9 patients had more than 10 crystals per slide. The microcrystals positive (MC+) group had significantly higher values for AST (69.8 +/- 1.7) (mean +/- SEM), ALT (123.3 +/- 28.1), FA (252 +/- 28.1), G-GT (144.6 +/- 26.7) and BT (1.83 +/- 0.37) than the microcrystals negative group: AST (19.6 +/- 2.5), ALT (28.3 +/- 5.8), FA (170.5 +/- 15.1), G-GT (54.3 +/- 10.7) and BT (0.76 +/- 0.09). The more 10 crystals group had higher values (AST: 82.0 +/- 29.1, ALT: 143.1 +/- 43.5, FA: 294.8 +/- 57.2, G-GT: 171.8 +/- 38.4, BT: 2.61 +/- 0.82) than in the microcrystals negative group. We concluded that in the absence of other overt causes, the presence of crystals in bile of patients with pancreatitis justifies etiology. The number is not important.

Liver injury is a manifestation of the systemic inflammatory response during acute pancreatitis. We have demonstrated that elastase induces macrophage tumor necrosis factor (TNF) production in distant organs, thus mimicking pancreatitis-associated organ injury. The aim of this study was to determine the mechanism by which elastase induces hepatic cytokine production. Rat livers (n = 40) were perfused with elastase +/- gadolinium (Gd) to inhibit Kupffer cells. Liver parenchymal enzymes and TNF were measured in the effluent. In vitro, rat hepatocytes or Kupffer cells were treated with elastase (1 U/ml) +/- Gd (0.5 mg/ml) or pyrrolidine dithiocarbamate (PDTC; 0.5 mg/ml). TNF protein, TNF messenger RNA, and NF-kappa B activation were determined. In vivo, Gd blunted the elastase-induced TNF production and decreased AST, ALT, LDH, and nonviable cells (propidium iodide) (P < or= 0.03 vs. elastase). In vitro, elastase induced TNF production from Kupffer cells (P < 0.001 vs. control) but not from hepatocytes. Gd or PDTC significantly attenuated the elastase-induced TNF production (P < 0.001). Elastase-induced overexpression of TNF messengerRNA and activation of NF-kappa B was attenuated by Gd. Pancreatic elastase induces a pattern of liver injury similar to that seen during acute pancreatitis by activating cytokine production and gene expression within Kupffer cells via NF-kappa B. Gd exhibits a protective effect against elastase-induced liver injury by inhibiting activation of NF-kappa B.

We have demonstrated that pancreatitis-associated ascitic fluid contributes to hepatocyte injury during acute pancreatitis; a phenomenon independent of ascites' enzymatic content and Kupffer cell-derived cytokines. Our aim is to characterize the mechanisms of pancreatitis-associated ascitic fluid induced hepatocyte death. NIH mice were injected intraperitoneally with pathogen-free pancreatitis-associated ascitic fluid. Twenty-four hours later, serum AST, ALT, LDH, and hepatocyte apoptosis (TUNEL) were measured. Human hepatocytes (CCL-13) were treated with pancreatitis-associated ascitic fluid +/-SB203580 or caspase-3 inhibitor-II. Mitochondrial membrane integrity was determined by DiOC6 staining. Apoptosis was measured by TUNEL staining and flow cytometry after dual labeling with Annexin-V/7-AAD. Data are mean +/- SEM of triplicates. Pancreatitis-associated ascitic fluid increased serum AST, ALT, LDH, and apoptotic cells in the mouse liver (all P < 0.03 vs. sham). In CCL-13 cells, pancreatitis-associated ascitic fluid induced a time and dose-dependent increase in apoptosis, in addition to p38-MAPK phosphorylation (P = 0.02 vs. control), caspase-3 cleavage (P < 0.03 vs. control) and decreased DiOC6 mitochondrial staining (P < 0.01 vs. control). Both caspase-3 inhibitor-II and SB203580 decreased apoptosis, but the former had no effect on DiOC6 staining. Pancreatitis-associated ascitic fluid induces liver injury and hepatocyte apoptosis by activating p38-MAPK and caspase-3 dependent pro-apoptotic pathways.

Saw palmetto is a frequently used botanical agent in benign prostatic enlargement (BPH). Although it has been reported to cause cholestatic hepatitis and many medical conditions, Saw palmetto has not been implicated in acute pancreatitis. We report a case of a probable Saw palmetto induced acute hepatitis and pancreatitis. A 55-year-old reformed alcoholic, sober for greater than 15 years, presented with severe non-radiating epigastric pain associated with nausea and vomiting. His only significant comorbidity is BPH for which he intermittently took Saw palmetto for about four years. Physical examination revealed normal vital signs, tender epigastrium without guarding or rebound tenderness. Cullen and Gray Turner signs were negative. Complete blood count and basic metabolic profile were normal. Additional laboratory values include a serum amylase: 2,152 mmol/L, lipase: 39,346 mmol/L, serum triglyceride: 38 mmol/L, AST: 1265, ALT: 1232 and alkaline phosphatase was 185. Abdominal ultrasound and magnetic resonance cholangiography revealed sludge without stones. A hepatic indole diacetic acid scan was negative. Patient responded clinically and biochemically to withdrawal of Saw palmetto. Two similar episodes of improvements followed by recurrence were noted with discontinuations and reinstitution of Saw Palmetto. Simultaneous and sustained response of hepatitis and pancreatitis to Saw palmetto abstinence with reoccurrence on reinstitution strongly favors drug effect. "Natural" medicinal preparations are therefore not necessarily safe and the importance of detailed medication history (including "supplements") cannot be over emphasized.

Practical guidelines for the diagnosis of acute pancreatitis are presented so that a rapid and adequate diagnosis can be made. When acute pancreatitis is suspected in patients with acute onset of abdominal pain and tenderness mainly in the upper abdomen, the diagnosis of acute pancreatitis is made on the basis of elevated levels of pancreatic enzymes in the blood and/or urine. Furthermore, other acute abdominal diseases are ruled out if local findings associated with pancreatitis are confirmed by diagnostic imaging. According to the diagnostic criteria established in Japan, patients who present with two of the following three manifestations are diagnosed as having acute pancreatitis: characteristic upper abdominal pain, elevated levels of pancreatic enzymes, and findings of ultrasonography (US), CT or MRI suggesting acute pancreatitis. Detection of elevated levels of blood pancreatic enzymes is crucial in the diagnosis of acute pancreatitis. Measurement of blood lipase is recommended, because it is reported to be superior to all other pancreatic enzymes in terms of sensitivity and specificity. For measurements of the blood amylase level widely used in Japan, it should be cautioned that, because of its low specificity, abnormal high values are also often obtained in diseases other than pancreatitis. The cut-off level of blood pancreatic enzymes for the diagnosis of acute pancreatitis is not able to be set because of lack of sufficient evidence and consensus to date. CT study is the most appropriate procedure to confirm image findings of acute pancreatitis. Elucidation of the etiology of acute pancreatitis should be continued after a diagnosis of acute pancreatitis. In the process of the etiologic elucidation of acute pancreatitis, judgment whether it is gallstone-induced or not is most urgent and crucial for deciding treatment policy including the assessment of whether endoscopic papillary treatment should be conducted or not. The diagnosis of gallstone-induced acute pancreatitis can be made by combining detection of elevated levels of bilirubin, transamylase (ALT, AST) and ALP detected by hematological examination and the visualization of gallstones by US.
