Survival of patients with HCV cirrhosis and sustained virologic response is similar to the general population.

2016

Background & Aims: Life expectancy of patients with compensated hepatitis C virus (HCV) cirrhosis achieving sustained virologic response (SVR) is limited by liver events as compared to the general population. Thus, survival benefit of SVR remains to be measured. Methods: The study includes prospective surveillance data from three cohorts of Italian patients with compensated HCV cirrhosis who achieved SVR on an interferon-based (IFN) regimen, compared to simultaneously observed non-SVR, untreated and decompensated patients. Overall survival was calculated from the date of start of IFN to death. The number of deaths expected during the at-risk period was determined by applying age- and se…

2017

Background Few studies examined the outcome of patients with hepatitis C virus (HCV)-related cirrhosis who developed hepatocellular carcinoma (HCC). The relative weight as determinant of death for cancer vs end-stage liver disease (ESLD) and the benefit of HCV eradication remain undefined. This multicentre, retrospective analysis evaluates overall survival (OS), rate of decompensation and tumour recurrence in compensated HCC patients treated with interferon (IFN) according to HCV status since HCC diagnosis. Methods Two groups of patients with HCV-related cirrhosis and HCC were followed since HCC diagnosis: (i) compensated cirrhotics with prior sustained virological response (SVR) on IFN-bas…

2010

The incidence of de novo development of esophageal varices (EV) in patients with compensated liver cirrhosis has been determined by few studies in the short term and never in the long term. The aims of the present study were to determine the incidence and the risk factors associated with the development of EV and to assess whether antiviral treatment and achievement of sustained virologic response (SVR) may prevent de novo EV development in patients with HCV-induced cirrhosis. We studied 218 patients with compensated EV-free, HCV-induced cirrhosis consecutively enrolled between 1989 and 1992 at three referral centers in Milan, Italy. Endoscopic surveillance was performed at 3-year intervals…

Retreatment with interferon plus ribavirin of chronic hepatitis C non-responders to interferon monotherapy: a meta-analysis of individual patient dat…

2002

Background and aims: Retreatment with a combination of α interferon (IFN) plus ribavirin of patients with chronic hepatitis C who did not respond to IFN monotherapy has not been assessed in large controlled studies. Methods: To assess the effectiveness and tolerability of IFN/ribavirin retreatment of non-responders to IFN and to identify predictors of complete (biochemical and virological) sustained response, we performed a meta-analysis of individual data on 581 patients from 10 centres. Retreatment with various IFN schedules (mean total dose 544 mega units) and a fixed ribavirin dose (1000–1200 mg/daily depending on body weight) was given for 24–60 (mean 39.5) weeks. Results: Biochemical …

Multicentre randomized placebo-controlled trial of ursodeoxycholic acid with or without colchicine in symptomatic primary biliary cirrhosis

2000

Aim: To establish the efficacy of combination therapy with ursodeoxycholic acid (UDCA) and colchicine in patients with symptomatic primary biliary cirrhosis (PBC), defined by the presence of liver cirrhosis, pruritus or bilirubin exceeding 2 mg/mL. Methods: A total of 90 patients were randomly assigned to ursodeoxycholic acid 500 mg/daily plus placebo (UDCA group, n=44), or ursodeoxycholic acid at the same dosage plus colchicine, 1 mg/daily (UDCA/C group, n=46). The two groups were comparable for age, sex, stage of disease, severity of pruritus, bilirubin, and Mayo score. All patients underwent clinical, ultrasonographic, and biochemical examinations at entry and then every 6 months up to 3…

Effect of different doses of ursodeoxycholic acid in chronic liver disease

1989

Recent clinical studies have indicated that ursodeoxycholic acid (ursodiol), administered at dosages ranging between 10 and 15 mg/kg/day, improves liver function indices in both cholestatic and inflammatory chronic liver diseases. These dosages would be considered high for the use of ursodiol in gallstone dissolution therapy. To investigate the dose-response relationship to ursodiol administration, we planned a few studies in patients with primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), and chronic hepatitis (CH). Patients with PBC were subdivided into two groups on the basis of their serum bilirubin values, with 2 mg/dl as the dividing line. Ursodiol was given at dos…

Tauroursodeoxycholic acid for the treatment of chronic hepatitis: a multicentre dose-response study

1998

Ursodeoxycholic acid (UDCA) improves the biochemical expression of chronic liver disease. Tauroursodeoxycholic acid (TUDCA) was recently shown to have more favourable metabolic properties. We designed a multicenter, randomized, controlled study, aimed at assessing the efficacy of TUDCA for the treatment of chronic hepatitis. One hundred and fifty-five patients with chronic hepatitis were randomly assigned to receive TUDCA at the daily doses of 250, 500 and 1000 mg, or no treatment for 6 months. Aminotransferase and gamma-glutamyl transpeptidase (GGT) serum levels decreased with each dose of TUDCA compared with controls (P<0.001). The 1000 mg dose was followed by more marked improvement comp…

X Chromosome Contribution to the Genetic Architecture of Primary Biliary Cholangitis

2021

Background &amp; aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease. Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals). Results: Single-marker association analyses found approximately 100 loci displaying P &lt; 5 × 10-4, with the most significant being a signal within the OTUD5 gene (rs3027490; P = 4.80 × 10-6; odds…

An international genome-wide meta-analysis of primary biliary cholangitis: Novel risk loci and candidate drugs.

2021

[BACKGROUND & AIMS] Primary biliary cholangitis (PBC) is a chronic liver disease in which autoimmune destruction of the small intra-hepatic bile ducts eventually leads to cirrhosis. Many patients have inadequate response to licensed medications, motivating the search for novel therapies. Previous genome-wide association studies (GWAS) and meta-analyses (GWMA) of PBC have identified numerous risk loci for this condition, providing insight into its aetiology. We undertook the largest GWMA of PBC to date, aiming to identify additional risk loci and prioritise candidate genes for in silico drug efficacy screening. [METHODS] We combined new and existing genotype data for 10, 516 cases and 20, 77…

Predicting Mortality Risk in Patients With Compensated HCV-Induced Cirrhosis: A Long-Term Prospective Study

2009

OBJECTIVES: The identification of prognostic factors associated with mortality is crucial in any clinical setting. METHODS: We enrolled in a prospective study 352 patients with compensated hepatitis C virus (HCV)-induced cirrhosis, consecutively observed between 1989 and 1992. At entry, patients underwent upper endoscopy to detect esophageal varices, and were then surveilled by serial clinical and ultrasonographic examination. The model for end-stage liver disease (MELD) score was calculated with information collected at enrollment. Baseline predictors and intercurrent events associated with mortality were assessed using the Cox regression model. RESULTS: During a median follow-up of 14.4 y…
