Sclerosing peritonitis is a severe complication after CAPD treatment. The visceral peritoneum is thickened and interenteric adhesive parts are found. Myofibroblasts are proliferated and the collageneous tissue is hyperplastic. The mean clinical symptom is the mechanical obstruction of the small bowel. We observed this illness in three out of sixty patients under CAPD. These patients had higher incidence of bacterial peritonitis. In the ascites high concentrations of PG E2 and Thromboxan B2 were observed. After treatment of the infection the concentrations fell down to normal values. Electronoptical observations from peritoneal biopsies showed a proliferation of myofibroblasts and extracellular lysosomes. It is known from these lysosomes that they are able to set free proteasis. These lead to degredation of fibrin and fibrinogen. These splits are mitogen to myofibroblasts. release from HIT cells could also be evoked by the sulphonylureas glibenclamide and tolbutamide and by an increase in concentration of extracellular K+ to 40 mmol/l. The content of cyclic AMP in HIT cells was increased modestly by glucose but not by an increase in extracellular K+. Forskolin elicited a 4-fold increase in cyclic AMP content. We conclude that HIT cells retain the essential features of the insulin secretory response of normal B cells and represent an important tool for further biochemical characterisation of the secretory system.

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.

Fifty-seven patients with decompensated cirrhosis were studied prospectively to assess the sensitivity and specificity of early clinical or biological signs of bacterial infection. Among them, 19 had proven infection on admission (7 spontaneous bacterial peritonitis, 5 bacteraemia, 3 urinary tract infections, 2 pneumonia, 1 dental abscess and 1 cholangitis). Fever, polymorphonuclear cell count, fibrinogen and C-reactive protein levels were found to be of little or no help in diagnosing bacterial infection on admission. Interleukin-6 plasma levels were, however, significantly different between infected (median: 1386 pg/ml, range: 237-20,000) and non-infected patients (median: 34 pg/ml, range: 0-4500, p < 0.00001). Levels above 200 pg/ml were always found in infected patients, giving a sensitivity of 100% and a specificity of 74%. C-reactive protein correlated weakly with interleukin-6 levels, indicating a defective acute-phase response in cirrhosis. Tumor necrosis factor alpha plasma levels were less sensitive (95%) and specific (68%) for the diagnosis of bacterial infection at a threshold of 50 pg/ml, but were more closely related to a poor patient outcome. In decompensated cirrhosis, interleukin-6 plasma levels on admission provided the most sensitive and specific tool for the diagnosis of bacterial infection.

To assess the diagnostic and prognostic value of interleukin-6, interleukin 1 beta, and tumor necrosis factor-alpha assays in plasma and ascites, we measured these cytokines in eight patients with malignancy-related ascites and 32 patients with decompensated cirrhosis. Five patients had an episode of bacterial peritonitis, during which one or more ascitic fluid samples were analyzed. Interleukin-6 and tumor necrosis factor-alpha were not significantly different between the cirrhotic and the malignant groups: ascitic interleukin-6 13,816 +/- 15,314 vs 28,138 +/- 23,403 pg/ml, plasma interleukin-6 542 +/- 719 vs 559 +/- 604 pg/ml; ascitic tumor necrosis factor-alpha 19 +/- 50 vs 12 +/- 31 pg/ml, plasma tumor necrosis factor-alpha 3.4 +/- 8.2 vs 6.1 +/- 13.8 pg/ml. During an episode of bacterial peritonitis there was a significant increase only in ascitic interleukin-6 (133,268 +/- 99,743 pg/ml), which declined after antibiotic treatment. None of the parameters was associated with 6-month survival (11 of the 40 patients died within 6 months). There was a correlation (r = 0.675; p = 0.002) between plasma interleukin-6 levels and the Child-Pugh score in patients with cirrhosis, but not with the etiology of the liver disorder. Plasma interleukin-6 levels correlated with IgA levels (r = 0.649; p = 0.004) but not with C reactive protein, sedimentation rate, fibrinogen, IgM or IgG. These results do suggest that interleukin-6 is produced within the peritoneal cavity in hepatic and malignant ascites. There is a sharp increase in the local production of interleukin-6 during an episode of bacterial peritonitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Staphylococcus aureus is a human pathogen that secretes proteins that contribute to bacterial colonization. Here we describe the extracellular adherence protein (Eap) as a novel anti-inflammatory factor that inhibits host leukocyte recruitment. Due to its direct interactions with the host adhesive proteins intercellular adhesion molecule 1 (ICAM-1), fibrinogen or vitronectin, Eap disrupted beta(2)-integrin and urokinase receptor mediated leukocyte adhesion in vitro. Whereas Eap-expressing S. aureus induced a 2 3-fold lower neutrophil recruitment in bacterial peritonitis in mice as compared with an Eap-negative strain, isolated Eap prevented beta(2)-integrin-dependent neutrophil recruitment in a mouse model of acute thioglycollate-induced peritonitis. Thus, the specific interactions with ICAM-1 and extracellular matrix proteins render Eap a potent anti-inflammatory factor, which may serve as a new therapeutic substance to block leukocyte extravasation in patients with hyperinflammatory pathologies.
