Studies of coagulation were performed prospectively in 41 patients with mild to moderately severe acute pancreatitis. Six patients (15%) presented with coagulation data suggestive of defibrination; two of them had clinical signs of bleeding. No other cause than
pancreatitis
was found in these 6 patients to account for coagulation abnormalities. Comparing the patients who presented defibrination to those who did not, no difference was observed in clinical course and admission values of serum amylase,
fibrinogen
, urea, calcium, glucose, transaminase levels, white blood cell count and arterial partial pressure of oxygen. Platelets counts and serum creatinine levels were respectively lower and higher in the first group of patients.

Alterations in coagulation factors have been reported during acute pancreatitis. Therefore the relationship of coagulation measurements to complications of
pancreatitis
was evaluated prospectively in 35 patients in whom 130 serial coagulation profiles were performed, consisting of
fibrinogen
, platelet count (PC),
fibrinogen
-fibrin-related-antigen (FR-antigen), prothrombin time (PT), partial thromboplastin time, thrombin time, euglobulin clot lysis, and Factors II, V and VII-X levels. During attacks of acute pancreatitis, over-all mean initial
fibrinogen
and PC of 268 mg. per 100 ml. and 214,000 per cubic millimiter rose significantly (p less than 0.005) to peaks of 362 mg. per 100 ml. and 477,800 per cubic millimeter by day 6 to 10. Mean initial FR-antigen of 4.8 microgram per milliliter rose to peak 7.4 microgram per milliliter on day 5. In 21 patients with mild
pancreatitis
, mean highest
fibrinogen
, PC, FR-antigen, and PT were 329 mg. per 100 ml., 361,500 per cubic millimeter, 5.3 microng per milliliter and 14.1 seconds. These values were significantly higher (p less than 0.05 to 0.01) in patients with severe
pancreatitis
, being 422 mg. per 100 ml. 528,000 per cubic millimeter, 13.7 microng per milliliter, and 15.5 seconds, respectively. Evaluation of the relationship of coagulation measurements to early clinical features showd that mean initial
fibrinogen
levels were significantly higher (p less than 0.05 to 0.01) in patients with initial amylase greater than 1,000 Somogyi units percent, serum glutamic oxaloacetic transaminase (SGOT) greater than 250 S.F.U. percent, and initial 72 hour PAO2 less than 75 mm. Hg. Early hypoxemia also correlated (p less than 0.05) with elevated initial FR-antigen levels. Impaired early renal function correlated (p less than 0.01) with elevated initial PC only. Early hypocalcemia did not correlate with coagulation measurements. These findings demonstrate that marked changes in coagulation parameters occur during acute pancreatitis and are related to over-all morbidity. Correlation of early coagulation measurements with amylase levels and with respiratory, renal, and hepatic dysfunction suggests that enzyme-related intravascular coagulation may be implicated in the pathogenesis of these complications of
pancreatitis
.

The
fibrinogen
related antigens were measured in 22 consecutive patients with acute pancreatitis. During the attack a marked elevation was seen, the values normalizing in the quiet phase. This may be due to either intravascular and/or extravascular degradation of
fibrinogen
-fibrin. As other authors have demonstrated intravascular coagulation experimentally in animals with
pancreatitis
, the authors stress that intravascular coagulation may play an important role in the patheogenesis of acute pancreatitis.

It is well known that fibrinolytic activity in the early stages of acute experimental
pancreatitis
(AEP) as assessed by euglobulin lysis time (ELT) is depressed. The aim of this study was to evaluate changes in the fibrinolytic system in the early stages of taurocholate AEP in rats. Tissue plasminogen activator (t-PA) activity, plasminogen activator inhibitor 1 (PAI-1) activity, plasminogen, alpha 1 proteinase inhibitor (alpha 1 PI), alpha 2 antiplasmin (alpha 2 AP), antithrombin III (AT III),
fibrinogen
, and ELT were measured 0.5, 1, 3, and 6 h after the induction of taurocholate AEP in rats, as well as in sham-operated animals and the control group, which was not submitted to any operation. T-PA activity decreased significantly after 3 and 6 h of AEP; PAI activity had a time course reverse to t-PA and was parallel to alpha 1 PI activity. ELT was slightly prolonged after 0.5, 1, and 3 h, whereas alpha 2 AP activity and plasminogen levels increased significantly; AT III activity was increased after 1 h in comparison to control group. Sham operation caused nonsignificant changes in fibrinolysis. Increase of PAI activity and decrease of t-PA could be a reasonable explanation for inhibited plasma euglobulin fibrinolytic activity noted in the early period of AEP.

The detection of TATC may inform about the presence of thrombin generation and, and hence of a pre-thrombotic status. An ELISA test (Enzygnst TAT) has been developed here in order to evaluate the predictive role played by TATC, and it was applied on 182 patients who distributed in 14 with cirrhosis of the liver, 11 with sepsis, 17 with chronic arterial insufficiency, 55 with neoplasms, 9 with thrombosis, 15 in postoperative period, 15 with pneumonia, 16 with disseminated intravascular coagulation (DIC), 14 with multiple injuries and 16 with
pancreatitis
. TATC levels were significantly increased in all groups with regard to the control group. Patients with thrombosis, sepsis, multiple injuries, DIC and in the postoperative period showed especially high TATC figures. No correlation between TATC and
fibrinogen
, platelet count, activated partial thromboplastin time or prothrombin complex assay was found in the post-operative patient-group. It was concluded that TATC are a good indicator of hypercoagulability.

Serum pancreatic enzymes (amylase, trypsin, pancreatic elastase 1, pancreatic phospholipase A2) and serum pancreatic secretory trypsin inhibitor (PSTI) were measured in 22 patients with moderate or severe acute pancreatitis. Serum levels of all pancreatic enzymes were elevated at the initial determination, but they fell rapidly to normal in both moderate and severe
pancreatitis
. In contrast, PSTI in severe
pancreatitis
increased after admission and reached the maximum on the second to the forth day after onset. There was a significant positive correlation between the level of PSTI and that of acute phase reactant (
fibrinogen
, alpha 1-antitrypsin), and serum PSTI in severe acute pancreatitis changed as if it was one of acute phase reactants. There was also a significant negative correlation between the level of serum PSTI and that of alpha 2-macroglobulin.

The coagulation and fibrinolytic systems were analysed parallel to the clinical evaluation in 27 attacks of acute human
pancreatitis
of different severity. Consumptive coagulopathy was evident from decreased platelet counts, decreased prothrombin values and consumption of
fibrinogen
during the first days in severe attacks. Fibrinolysis was suggested by decreased plasminogen values and the presence of
fibrinogen
degradation products. All main protease inhibitors of the two systems showed protease-antiprotease complexation and lower functional than quantitative values. Functional levels of the protease inhibitors were almost zero in the peritoneal fluid in severe attacks. It is concluded that severe acute pancreatitis results in consumptive coagulopathy and fibrinolysis together with a local antiprotease deficiency. All the changes are closely correlated to the severity of the disease.

Acute pancreatitis was induced in rats by infusing sodium taurodeoxycholate with or without Escherichia coli and Bacteroides fragilis into the bile-pancreatic duct. Survival did not differ between the 'noninfected bile group' (NIB) and the 'infected bile group' (IB). At standardized macroscopic evaluation,
pancreatitis
was more severe in the IB group (p less than 0.05). Histologic examination on day 7 showed suppuration of pancreatic tissue in 6/7 IB and 3/14 NIB rats (p less than 0.05). Bacteriologic culture of pancreatic tissue was positive in 6/8 IB and 3/17 NIB rats (p less than 0.01). Bacterial culture of blood, peritoneal fluid of pulmonary tissue was seldom positive. Concordance between microscopically observed suppuration and positive bacterial culture was almost total. Recall antigen skin testing indicated anergy in the IB group, while the NIB group showed moderately diminished reaction (p less than 0.001). Similar increase of S-
fibrinogen
was found on day 3 in both groups, but complement factor C3 was reduced only in the IB group. This experimental model, with suppurative
pancreatitis
induced by intraductal infusion of an infected bile salt, may be useful for studies of systemic complications in acute pancreatitis.

Twenty-seven attacks of acute human
pancreatitis
of different severity were analysed concerning clinical outcome and activation of the coagulation and fibrinolytic systems. Consumptive coagulopathy was suggested by decreased platelet counts, decreased prothrombin values and consumption of
fibrinogen
during the first days in severe attacks. Factor X was slightly decreased the first 5 days in all attacks. Increased fibrinolysis was suggested by decreased plasminogen values in severe attacks.
Fibrinogen
degradation products were seen in 40% of the patients in blood and in 100% of the patients in the peritoneal fluid. The four main protease inhibitors of the two systems all showed protease-antiprotease complexation and lower functional than quantitative values. Plasma levels of antithrombin III and alpha 2-macroglobulin were low, while the levels of C1-inhibitor and alpha 2-antiplasmin were high. Functional levels of all the four protease inhibitors were almost zero in the peritoneal fluid in severe attacks. It is concluded that severe acute pancreatitis results in both consumptive coagulopathy and in increased fibrinolysis. A local antiprotease deficiency is seen in the peritoneal cavity and high levels of protease-antiprotease complexes are also seen in plasma. All these changes are closely correlated to the severity of the disease and may probably determine the clinical outcome of the acute attack.
