HBV reactivation in patients with HCV/HBV cirrhosis on treatment with direct-acting antivirals

2017

Anecdotal reports suggest that patients with chronic hepatitis C virus (HCV) hepatitis and overt or occult hepatitis B virus (HBV) coinfection may reactivate HBV when HCV is suppressed or cleared by direct-acting antivirals (DAAs). We assessed the prevalence of overt or previous HBV coinfection and the risk of HBV reactivation in patients with HCV cirrhosis treated with DAAs. This was a retrospective cohort of 104 consecutive patients with HCV cirrhosis treated with DAAs. Serum HCV-RNA and HBV-DNA were tested at weeks 4, 8 and 12 of DAAs therapy and at week 12 of follow-up. At the start of DAAs, eight patients (7.7%) were HBsAg positive/HBeAg negative with undetectable HBV-DNA and low level…

Early experiences from one of the first treatment programs for chronic hepatitis B in sub-Saharan Africa

2017

Treatment for chronic hepatitis B (CHB) is virtually absent in sub-Saharan Africa. Here we present early experiences from a pilot program for treatment of CHB in Ethiopia. Adults (≥18 years) with CHB were included in a cohort study at St. Paul’s Hospital Millennium Medical College, Addis Ababa, from February 2015. The baseline assessment included liver function tests, viral markers and transient elastography (Fibroscan 402, Echosense, France). Logistic regression models were used to identify predictors of fibrosis. Tenofovir disoproxil fumarate (TDF) was initiated based on the European Association for the Study of the Liver (EASL) criteria, with some modifications. The initial 300 patients …

Prognostic factors and outcomes of patients with hepatocellular carcinoma in non-cirrhotic liver

2012

To report the outcome of patients with hepatocellular carcinoma (HCC) in non-cirrhotic liver depending on the mode of primary treatment and to define clinicopathological factors influencing patients' prognosis.A retrospective analysis of an unselected cohort of 105 patients was performed. Overall survival (OS) was estimated by the Kaplan-Meier method and potentially prognostic factors were analyzed in Cox regression models.OS of the whole cohort at 1, 3, and 5 years was 66%, 47%, and 29%, respectively. Tobacco consumption, ECOG0, macroscopic vascular invasion, continuous tumor diameter, and treatment other than resection were predictors of decreased OS in the whole cohort. Resection was per…

Predictive factors of transarterial chemoembolisation toxicity in unresectable hepatocellular carcinoma

2013

Abstract Background Transarterial chemoembolisation (TACE) is an effective treatment for unresectable hepatocellular carcinoma (HCC), but can cause severe toxicity. Aim To identify predictive factors of severe TACE-related toxicity in patients with unresectable HCC. Methods All HCC patients who underwent TACE at the Dijon University Hospital between 2008 and 2011 were included in this retrospective study. Severe TACE-related toxicity was defined as the occurrence of any adverse event grade ≥4, or any adverse event that caused a prolongation of hospitalisation of >8 days, or any additional hospitalisation within 1 month after TACE. Factors predicting toxicity were identified using a logistic…

Prospective Randomized Comparison of Minilaparoscopy and Percutaneous Liver Biopsy

2007

Liver cirrhosis represents an advanced stage of hepatic fibrosis characterized by distortion of organ architecture and formation of regenerative nodules. Retrospective series reported percutaneous liver biopsy to miss cirrhosis in about 30%. The aim of this study was to prospectively compare diagnostic sensitivity regarding the detection of cirrhosis and the complication rates of percutaneous versus minilaparoscopic liver biopsy in chronic liver disease.Eight hundred fifty-seven patients were randomized to percutaneous (415) or to minilaparoscopic liver biopsy (442). Macroscopic liver evaluation was documented as normal, fibrosis, or cirrhosis. Liver specimens were assessed blindly accordin…

Risk of cirrhosis-related complications in patients with advanced fibrosis following hepatitis C virus eradication

2017

Background & Aims: The risk of hepatocellular carcinoma (HCC) is reduced but not eradicated among patients with hepatitis C virus (HCV)-induced advanced hepatic fibrosis who attained sustained viral response (SVR). We aimed to assess the risk of cirrhosis-related complications in this specific group of patients. Methods: Data from previously reported Western cohort studies including patients with chronic HCV infection and bridging fibrosis or cirrhosis who attained SVR were pooled for survival analyses on the individual patient level. The primary endpoint was HCC and the secondary endpoint was clinical disease progression, defined as liver failure, HCC or death. Results: Included were 1…

Evaluation of 24-hour gastric acidity in patients with hepatic cirrhosis.

1996

Data from previous studies on gastric acid secretion in patients with hepatic cirrhosis are controversial, due, at least in part, to the possible interference of liver failure and altered gastric mucosal microcirculation on the pharmacological action of the substances used to stimulate the parietal cell. For this reason, we wished to investigate the circadian pattern of gastric acidity by means of continuous 24-hour pH monitoring, which permits measurement of pH fluctuations in a nearly physiological manner and does not require any pharmacological stimulus.Forty-nine patients with liver cirrhosis of different aetiology were recruited for this study. They underwent 24-hour gastric pH-metry w…

Comparison of resection and transarterial chemoembolisation in the treatment of advanced intrahepatic cholangiocarcinoma--a single-center experience.

2012

Abstract Aims The aim of this study is to evaluate factors associated with the outcome after surgical resection and to compare the efficacy of surgery to transarterial chemoembolisation (TACE) in patients with advanced intrahepatic cholangiocarcinoma (IHC). Materials and methods 273 patients with IHC treated in our department between 1997 and 2012 were included in our study. Patients were divided according to therapy into surgical ( n  = 130), TACE ( n  = 32), and systemic chemotherapy/best supportive care ( n  = 111) groups. Clinicopathological characteristics and survival were reviewed retrospectively. Results The 1-, 3-, and 5-year survival rates in patients after surgical resection were…

2014

Background & Aims The accuracy of noninvasive tools for the diagnosis of severe fibrosis in patients with nonalcoholic fatty liver disease(NAFLD) in clinical practice is still limited. We aimed at assessing the diagnostic performance of combined noninvasive tools in two independent cohorts of Italian NAFLD patients. Methods We analysed data from 321 Italian patients(179 Sicilian-training cohort, and 142 northern Italy-validation cohort) with an histological diagnosis of NAFLD. Severe fibrosis was defined as fibrosis ≥ F3 according to Kleiner classification. The APRI, AST/ALT, BARD, FIB-4, and NFS scores were calculated according to published algorithms. Liver stiffness measurement(LSM) was …

2013

Abstract OBJECTIVES: The occurrence of decompensation marks a crucial turning point in the course of cirrhosis. The purpose of this study was to assess the risk of mortality according to the clinical characteristics of first decompensation, considering also the impact of acute-on-chronic liver failure (AoCLF). METHODS: We conducted a prospective nationwide inception cohort study in Italy. Decompensation was defined by the presence of ascites, either overt or detected by ultrasonography (UD), gastroesophageal variceal bleeding (GEVB), and hepatic encephalopathy (HE). AoCLF was defined according to the Asian Pacific Association for the Study of the Liver criteria. Multivariable Cox proportion…
