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)
