Influence of 1-week Helicobacter pylori eradication therapy with rabeprazole, clarithromycin, and metronidazole on 13C-aminopyrine breath test.

Helicobacter pylori eradication therapy is commonly prescribed in the general population. Treatment consists of drugs that are mainly metabolized by the liver cytochrome P-450 (CYP) enzymatic pool. Most H.

13C-galactose breath test and 13C-aminopyrine breath test for the study of liver function in chronic liver disease.

Background And Aims: Liver biopsy examination is the gold standard to diagnose the presence of cirrhosis. The aim of this study was to evaluate the accuracy of both 13 C-aminopyrine breath test ( 13 C-ABT) and 13 C-galactose breath test ( 13 C-GBT) in the noninvasive assessment of the presence of cirrhosis in patients with chronic liver disease.

Methods: We evaluated 61 patients with chronic liver disease of diverse etiologies (21 compensated cirrhosis).

Effects of the association of lansoprazole, clarithromycin and metronidazole for helicobacter Pylori eradication therapy, measured by the 13C Aminopyrine breath test.

Background: Lansoprazole (LAN) is a proton pump inhibitor drug (PPI) metabolized by the P-450 liver cytochrome (CYP-450) system. LAN is used in association with antimicrobial agents in Helicobacter pylori (HP) eradication therapy. The 13C-Aminopyrine breath test (ABT) is a non-invasive tool exploring liver CYP-450 metabolic activity.

Can inclusion of serum creatinine values improve the Child-Turcotte-Pugh score and challenge the prognostic yield of the model for end-stage liver disease score in the short-term prognostic assessment of cirrhotic patients?

Background: The model for end-stage liver disease (MELD) score is a useful tool to assess prognosis in critically ill cirrhotic patients. However, its short-term prognostic superiority over the traditional Child-Turcotte-Pugh (CTP) score has not been definitely confirmed. The creatinine serum level is an important predictor of survival in patients with liver cirrhosis.

Relationship between thrombopoietin serum levels and liver function in patients with chronic liver disease related to hepatitis C virus infection.

Objectives: Thrombopoietin (Tpo) is an important regulator of megakaryocyte maturation and platelet production, and is mainly produced by the liver. A decrease in Tpo production is partly responsible for the thrombocytopenia observed in patients with chronic liver disease (CLD). The aim of this study was to evaluate the relationship between Tpo serum levels and liver function in patients with CLD related to hepatitis C virus (HCV) infection.

The 1-year and 3-month prognostic utility of the AST/ALT ratio and model for end-stage liver disease score in patients with viral liver cirrhosis.

Objectives: The AST/ALT ratio has shown good diagnostic accuracy in patients with chronic viral liver disease. However, its prognostic utility has never been tested. Recently, the Model for End-Stage Liver Disease (MELD) has been proposed as a simple and effective tool to predict survival in patients with liver cirrhosis.

Serum thrombopoietin levels are linked to liver function in untreated patients with hepatitis C virus-related chronic hepatitis.

Background: Thrombocytopenia can be found in patients with chronic hepatitis related to hepatitis C virus (HCV). Both hypersplenism and decreased liver production of thrombopoietin (TPO) have been hypothesized as mechanisms responsible for thrombocytopenia.

Aims: To assess the presence of relationships among platelet count, spleen size, TPO serum levels, liver histology, and liver function in a group of patients with HCV-related chronic hepatitis.

Monitoring of liver metabolic function during interferon-alpha therapy and its relationship to treatment outcome in chronic hepatitis C patients.

Background/aims: Interferon is considered the cornerstone in the therapy of chronic hepatitis C patients. Experimental studies have shown that interferon administration may influence liver metabolic activity. However, data concerning the monitoring of liver metabolic function during a therapeutic course of interferon in chronic hepatitis C patients are scanty.
