We investigated whether, in Italian patients, C-reactive protein (CRP) determination could be considered a useful adjunct, complementary to alpha 1-fetoprotein, in the detection of liver cancer. CRP was determined by particle-enhanced nephelometry in 171 subjects (102 male, 69 female). Fifty-five patients had mild chronic liver disease (CLD), 45 cirrhosis (CIR), 38 hepatocellular carcinoma (HCC); 33 subjects were healthy controls. Patients with HCC and CIR had higher CRP levels (P < 0.05) than those found in patients with CLD and controls. CRP higher than 5 mg/l was found in 30/38 (78.9%) patients with HCC, 28/45 (62.2%) patients with CIR, 16/55 (29.1%) patients with CLD (chi 2 56.0, P < 0.0001). Sensitivity, specificity and diagnostic accuracy of CRP in diagnosing HCC with respect to CLD+CIR were: 78.9%, 56.0% and 34.9%. However, when considered only in the subgroup of patients with alpha 1-fetoprotein below or equalling 30 ng/ml, they were 50.0%, 54.3% and 4.3% respectively. In conclusion, CRP concentration is frequently elevated in patients with HCC, however, it does not seem to improve the ability of alpha 1-fetoprotein to discriminate HCC from CIR.

We investigated 37 patients with ascites and liver cirrhosis in order to examine whether on the basis of correlation of cytokines and acute phase proteins of the ascitic fluid, prognosis of spontaneous bacterial peritonitis can be made. Significantly enhanced levels of interleukin-6, as well as acute phase reactants alpha-1-antitrypsin and C-reactive protein were found in the ascitic fluid of patients with spontaneous bacterial peritonitis. The levels of tumour necrosis factor alpha (TNF-alpha), neopterin, interleukin 2-receptor and granulocyte-macrophage colony stimulating factor were higher in patients with spontaneous bacterial peritonitis, but without statistical significance, whereas no differences were found between the interferon gamma, interleukin-2 and interleukin-1 levels. In addition, interleukin-6, TNF-alpha and neopterin levels were found to correlate significantly with the outcome of the disease. These findings show that acute phase reaction occurs in the ascitic compartment in correlation with the development of spontaneous bacterial peritonitis.

The in vitro effects of sera of 11 patients with liver cirrhosis on protein synthesis in PLC/PRF/5 cells were studied. Hepatitis B virus (HBV) infection was documented in 7 patients. Increased random production of several cell proteins of M(r) of approximately 25, 65, 90 and 130 K was shown by SDS-polyacrylamide gel electrophoresis (SDS-PAGE). There was no correlation between HBV-positive and HBV-negative cirrhosis and the induced proteins. One of them was identified as alpha-1 foetoprotein by immunoblot analysis. C-reactive protein (CRP) was determined only in one case; production of interleukin-6 (IL-6) was not detected.

The hepatic acute phase response after orthotopic transplantation (OLT) was studied in patients with fulminant hepatic failure (FHF) and with cirrhosis, in relation to the pre-existing disease. Plasma levels of C-reactive protein (CRP) increased significantly on day 1 after OLT in both the FHF (delta = 58 micrograms/ml) and cirrhosis (delta = 94 micrograms/ml) groups and reached a peak 4-5 days post surgery. alpha 1-Antitrypsin reached normal levels on day 1 post-transplant and fibrinogen reached normal levels on the 3rd day. The main stimulator of acute phase protein synthesis IL-6 was significantly increased pre-OLT in plasma in both FHF (median 54 pg/ml) and cirrhosis (median 8.7 pg/ml) patients compared to controls (2.35 pg/ml, P < 0.05). After OLT, IL-6 decreased rapidly in patients with FHF, indicating either removal of the source of IL-6 or clearance by the transplanted liver. In patients with cirrhosis, plasma IL-6 remained low, except in three patients who developed infection/rejection and whose IL-6 levels rose above 100 pg/ml. In conclusion, there is a marked acute phase response in the liver graft after transplantation, irrespective of the aetiology of the liver disease for which the transplant was performed.

Malnutrition in patients with liver cirrhosis is currently associated with abnormal fuel metabolism. The aim of this study was to evaluate changes in energy production and substrate oxidation rates in a group of 26 nonanorectic severely malnourished cirrhotic patients in stable clinical condition after 1 month of an oral diet. Child-Pugh score, nutritional status, energy expenditure, rates of nutrient oxidation, and plasma levels of intermediary metabolites in the postabsorptive phase were assessed before and after 1 month of oral nutrition. Upon entry onto the study, caloric and protein intakes were 40.1 +/- 2.0 kcal/kg and 1.44 +/- 0.8 g/kg, respectively. The Child-Pugh score did not change during the study, whereas nutritional status improved as shown by increased muscular midarm circumference, ([MMAC] P < .02), height-creatinine index (P < .05), triceps skinfold thickness ([TST] P < .01), and fat mass (P < .001). Inflammatory state improved during the study, as shown by the decrease of C-reactive protein ([CRP] P < .01) and orosomucoid (P < .001). The ratio of caloric intake to resting energy expenditure (REE) increased (1.53 +/- 0.06 v 1.66 +/- 0.07, P < .05), as well as the rate of glucose oxidation ([Gox] 73.6 +/- 9.9 v 128.1 +/- 10.3 mg/min, P < .001) and urine nitrogen excretion (6.69 +/- 0.47 v 7.96 +/- 0.48 g/d, P < .02). On the other hand, the rate of lipid oxidation (Lox) decreased (67.3 +/- 3.9 v 47.3 +/- 4.9 mg/min, P < .001) and was correlated with the decrease of free fatty acid (FFA) levels (P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)

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.

alpha 1-Acid glycoprotein, an acute phase reactant synthesised by the liver, has been reported to be increased in neoplastic conditions and reduced in chronic liver disease. We measured serum alpha 1-acid glycoprotein by a nephelometric method in 186 subjects (112 males, 74 females): 55 had mild chronic liver disease (chronic hepatitis and steatofibrosis), 45 cirrhosis, 38 hepatocellular carcinoma, 15 extra-hepatic malignant disease; 33 healthy subjects were used as controls. Analysis of variance demonstrated a significant variability among groups (F = 17.08, P = 0.0000). Higher concentrations of alpha 1-acid glycoprotein were detected in malignant extra-hepatic disease than in all other groups (P < 0.01); concentrations of alpha 1-acid glycoprotein were higher in hepatocellular carcinoma than in cirrhosis (P < 0.01). Multiple regression analysis by groups (dependent variable = alpha 1-acid glycoprotein; group 1 = mild chronic liver disease + cirrhosis; group 2 = hepatocellular carcinoma) showed a significant correlation for both group 1 (r = 0.6264, F = 8.005, P = 0.0000) and group 2 (r = 0.8947, F = 13.643, P = 0.0000). The significant standardised regression coefficients were: cholinesterase, C-reactive protein, gamma-glutamyltransferase and iron (negative) for regression upon group 1; C-reactive protein, alpha 1-antiproteinase, gamma-glutamyltransferase, iron (negative) for regression upon group 2. A difference between the 2 regression equation coefficients was detected (F = 5.209, P = 0.0002).(ABSTRACT TRUNCATED AT 250 WORDS)

The proinflammatory cytokines interleukin-1 and tumor necrosis factor-alpha are thought to play important roles in the pathophysiology of liver disease. Specific antagonists of these cytokines have been found in recent years. Interleukin-1 receptor antagonist is a specific interleukin-1 antagonist. The soluble receptor derived from the cell-surface p55 tumor necrosis factor receptor p55 is a naturally occurring substance that inhibits the biological effects of tumor necrosis factor. We used specific radioimmunoassays to detect circulating interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor p55 levels in 14 patients with acute viral hepatitis and in 160 patients with various chronic liver diseases. Levels of interleukin-1 receptor antagonist and, especially, tumor necrosis factor soluble receptor were markedly increased in most patients with chronic liver disease regardless of pathogenesis and in viral hepatitis. Patients with chronic liver disease and cirrhosis showed significantly higher levels of both cytokine antagonists than did noncirrhotic patients. Correlations between interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor were more significant than those of either antagonist with C-reactive protein or blood sedimentation rate. Interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor levels were also positively correlated with bilirubin and AST levels. We conclude that circulating levels of interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor may reflect ongoing disease activity and probably modulate some effects of endogenous interleukin-1 and tumor necrosis factor.

A 58-year-old male who had been diagnosed as hepatic cirrhosis four years previously was admitted to our hospital because his serum C-reactive protein (CRP) level had gradually risen, reaching 139 mg/dl. No inflammation findings were observed subjectively or objectively. Close examination revealed his CRP reaction to be false positive. His serum CRP showed positive only in a latex agglutination method using goat anti-CRP IgG. This false-positive reaction was thought to be owing to the abnormally glycosylated IgM, which has an affinity for the goat serum IgG.

We measured serum erythropoietin (EPO) immunoenzymatically in 245 subjects (151 male, 94 female) to investigate the pathophysiology of its liberation in patients with liver disease. Twelve patients had acute hepatitis, 60 mild chronic liver disease (CLD), 50 cirrhosis (CIR), 43 hepatocellular carcinoma (HCC), 16 malignant extrahepatic disease, 32 benign extrahepatic disease (BEN); 32 subjects served as healthy controls. Higher EPO levels were found in all groups of patients as compared with controls (Bonferroni's test, P < 0.01); CIR and HCC had higher values than CLD and BEN (P < 0.01). By multiple regression analysis, EPO correlated with haematocrit, cholinesterase and C-reactive protein (F = 18.63, P < 0.0001). Thus, circulating EPO increases in patients with liver disease, particularly in its more advanced forms. Besides anaemia, both impairment of liver function (possibly via decreased EPO metabolism) and inflammation seem to play contributory roles in elevating serum EPO.
