Fibrin deposition in response to bacterial peritonitis appears to predispose to residual infection in the peritoneal cavity. Our previous studies have demonstrated that intraperitoneal fibrinolysis using human recombinant tissue plasminogen activator (t-PA) prevented abscess formation in a rat intra-abdominal sepsis model. To investigate the potential adverse side effects of its use in the peritoneal cavity, the effect of t-PA on colonic anastomotic wound healing and on systemic coagulation parameters was examined in the rat. T-PA did not adversely affect colonic healing five and ten days after anastomosis. In animals infected intraperitoneally at the time of the anastomosis, t-PA reversed the inhibition of healing induced by perianastomotic abscesses at five days. This effect was mediated by the ability of t-PA to prevent perianastomotic abscess formation. After intraperitoneal administration, t-PA had no effect on prothrombin and partial thromboplastin times in either uninfected or infected animals and there was no evidence of clinical bleeding related to its use. These studies suggest that intraperitoneal fibrinolysis using t-PA may provide a safe, effective form of adjuvant therapy in the management of fibrinopurulent peritonitis.

Endotoxin levels and mononuclear phagocyte thromboplastin activities in samples from peripheral blood and peritoneal fluid were determined in nine patients with secondary bacterial peritonitis (appendicitis with perforation, or diverticulitis) and in five control patients (uncomplicated duodenal ulcer or gallbladder stones). None or only negligible amounts of endotoxin, always less than 0.01 ng/dl (contamination), and no growth of bacteria were detected in controls. In the patients with peritonitis, peritoneal fluid samples always contained gram-negative bacteria, and large amounts (mean, 31.6 ng/dl) of endotoxin were seen. Plasma from these patients also contained endotoxin (mean, 0.56 ng/dl) despite negative blood cultures. Mononuclear phagocytes from controls had low thromboplastin values, whereas both circulating monocytes and peritoneal macrophages from peritonitis patients showed a substantial increase (multifold) of thromboplastin.

One hundred sixty-five patients with cirrhosis diagnosed by needle liver biopsy were followed for 2 years to evaluate the relation between clotting factors and survival. Patients with spontaneous bacterial peritonitis, hepatic carcinoma, and cholestatic liver diseases were excluded. Patients were classified as A (n = 34), B (n = 75), or C (n = 56) according to Child-Pugh criteria. During the follow-up 45 patients died of liver failure or gastrointestinal hemorrhage. Nonsurvivor patients had significantly higher values of bilirubin and D-dimer, a marker of fibrinolysis in vivo, lower values of albumin, prothrombin activity, fibrinogen, prekallikrein, factor VII, and a more prolonged activated partial thromboplastin time than survivors. All these variables and Child-Pugh classification were significantly associated with survival in a univariate analysis. Multivariate analysis (Cox's model) showed that only prekallikrein and factor VII were independently predictors of survival. Ninety-three percent of patients with prekallikrein values < 32% died within 32 months of follow-up, whereas factor VII < 34% identified 93% of patients who died within 10 months of follow-up. This study suggests that factor VII is an early predictor of survival and may be a useful test to better identify cirrhotic patients who should be candidates for liver transplantation.

We describe two patients awaiting orthoptic liver transplantation in whom diagnostic paracentesis for the diagnosis of spontaneous bacterial peritonitis led to major hemorrhage. Accordingly, we advise caution in patients such as ours, particularly if the prothrombin time or partial thromboplastin time is more than twice the control value.
