HCV viraemia is more important than genotype as a predictor of response to interferon in sicily (Southern Italy)

Abstract Background/Aims: To investigate host- and virus-related factors predictive of early and sustained alanine aminotransferase normalization after interferon therapy for HCV-related chronic liver disease, in an area where genotype 1 is highly prevalent. Methods: We studied 100 patients with HCV-RNA positive chronic liver disease (73 chronic hepatitis and 27 cirrhosis) undergoing alpha-interferon treatment. Thirty-four patients had an early response but relapsed, 15 patients remained into sustained response for at least 12 months after therapy, and 51 patients did not respond. Serum HCV-RNA levels were assessed by bDNA (Chiron), and genotype by LiPA (Innogenetics) and by sequencing of t…

VCS: a Cheap and Fast Parameter for Early Diagnosis of Severe Sepsis and Septic Shock

Use of Thromboelastography in severe sepsis a case-control Study

Thromboelastography (TEG) is a global test of coagulation that records the viscoelastic changes in blood during clot formation. Cardiosurgery and liver transplantation are established fields of application for TEG. Severe sepsis is often characterized by an imbalance of the haemostatic equilibrium between clot formation and fibrinolysis in favor of a procoagulant status, especially in the first phase. A hypocoagulant status due to coagulation factor consumption could occur later. In spite of this, the correlation between TEG and sepsis is not clearly established. Moreover, there are doubts about which TEG-detected variable is best correlated with sepsis. The aim of this study is to clarify …

Immunoblotting as a confirmatory test for antimitochondrial antibodies in primary biliary cirrhosis.

Primary biliary cirrhosis is characterised by the presence of antimitochondrial antibodies which are directed against components of mitochondrial dehydrogenase complexes. The specificity of antimitochondrial antibodies for primary biliary cirrhosis as detected by immunoblotting was investigated. Commercially available preparations of pyruvate and oxo-glutarate dehydrogenases and beef-heart mitochondria were used as source of antigens. Sera from 47 primary biliary cirrhosis patients (46 of whom were antimitochondrial antibody positive by immunofluorescence), 16 non-primary biliary cirrhosis patients (antimitochondrial antibody positive by immunofluorescence), 23 liver-kidney microsomal antib…

Evaluation of automated hematologic VCS parameters in severe sepsis and septic shock: a case-control study.

A cheap and quick hematologic diagnostic parameter for detection of sepsis would have both economic and therapeutic benefits. The Coulter LH series hematology analyzer uses the VCS technology (Volume, Conductivity, Laser Scatter) providing information about cell volume, size, internal structure, and surface morphology. Many authors analyzed the clinical usefulness of VCS parameters in reactive neutrophils for detection of sepsis. An increase in mean cell volume and a decrease in mean light scatter in septic patients have been described. Our aim is to verify the correlation between VCS parameters and sepsis.

Intra-hospital Transsport of Crititically Ill Patients: Incidence of Adverse Events in One University Hospital

Use of CD64 for the diagnosis of sepsis: a case-control study.

CD64 is the high-affinity receptor of IgG. It is upregulated by inflammatory cytokines on neutrophils. The upregulation of CD64 is linked with PMN activation in SIRS or sepsis. Our aim is to verify these correlations.

Hepatitis C Viremia in Chronic Liver Disease: Relationship to Interferon-α or Corticosteroid Treatment

We assessed the pattern of hepatitis C viremia in chronic liver disease by studying 100 hepatitis C virus antibody–positive patients: 48 with chronic hepatitis, 21 with cirrhosis and 31 with hepatocellular carcinoma and cirrhosis. Serum hepatitis C virus RNA was detected by means of both the conventional nested polymerase chain reaction and a newly developed assay based on branched DNA that can also quantify viremia. Hepatitis C virus RNA was found in 94 of 100 patients with polymerase chain reaction and in 71 of 100 patients with branched-DNA (p < 0.001). Mean viremia level (× 103 genome equivalents/ml ± S.D.), as assessed with the branched-DNA test, was 5,700 ± 7,618 in the 48 patients wi…

Serum hepatitis C virus (HCV)-RNA and response to alpha-interferon in anti-HCV positive chronic hepatitis

Hepatitis C virus (HCV) replication was assessed before and during alpha-interferon (IFN) treatment in 22 anti-HCV positive patients with posttransfusion or sporadic chronic hepatitis (CH). Eleven patients were “responders” and 11 patients “non-responders” to IFN. Thirteen anti-HCV negative healthy subjects and five anti-HCV negative patients with autoimmune CH served as controls. Serum HCV-RNA was detected by the polymerase chain reaction (PCR) in all untreated anti-HCV positive patients but in none of the anti-HCV negative subjects. PCR primers from the 5′-non-coding (NC) region were more sensitive than primers from a non-structural (NS5) region in detecting HCV-RNA (21/22, 95% vs. 7/22, …

Hepatitis C virus infection as a risk factor for hepatocellular carcinoma in patients with cirrhosis. A case-control study.

Objective To determine whether chronic hepatitis C virus (HCV) infection is an independent risk factor for hepatocellular carcinoma and whether it increases the cirrhosis-related risk for hepatocellular carcinoma. Design Two pair-matched case-control studies. Setting A referral-based hospital. Patients In study I, 212 patients with hepatocellular carcinoma (197 of whom had known underlying cirrhosis) were compared with controls who had chronic nonhepatic diseases. In study II, the 197 patients with hepatocellular carcinoma and cirrhosis were compared with 197 pair-matched controls who had cirrhosis but not hepatocellular carcinoma. Measurements Levels of antibody to HCV (anti-HCV), hepatiti…
