Leucocyte Interferon-alpha for Patients with Chronic Hepatitis C Intolerant to Other alpha-Interferons

2003

Background: Alpha-interferon (α-IFN) is the treatment of choice for chronic hepatitis C but most patients experience adverse effects which sometimes lead to the suspension of therapy. Recently, higher doses of α-IFN or prolonged therapy have increased the number of cases of intolerance. Study Design: In this open study we evaluated the efficacy and safety of leucocyte interferon-alpha (IFNα) [6MU three times a week] in 43 patients with chronic hepatitis C who had been intolerant to previous treatment courses with recombinant or lymphoblastoid IFNα. All patients were treated for 6 months and followed-up for an additional 6 months. End of treatment responders were patients in whom hepatitis C…

Percutaneous liver biopsy: a safe outpatient procedure?

2001

Following the discovery of hepatitis C virus, more liver biopsies (LB) than before are being performed to assess the severity of liver disease. In this study, following the recommendations for outpatient LB made by the Patient Care Committee of the American Gastroenterological Association, we assessed the feasibility and benefits of LB performed as an outpatient versus inpatient procedure over the last 7 years in our centre. The study included 1,581 patients consecutively examined in our institute; all LBs were performed by a single operator with a 16-gauge needle using the Menghini technique, and in all cases the puncture site was determined using prebiopsy ultrasound. Liver lesions were c…

Intravenous natural beta-interferon in white patients with chronic hepatitis C who are nonresponders to alpha-interferon.

1998

Objectives: α-Interferons (α-IFN) have been shown to be effective in the treatment of chronic viral C hepatitis, but their efficacy remains unsatisfactory. Recently natural β-interferon (β-IFN) administered by intravenous infusion has been used successfully. Methods: To evaluate the efficacy and safety of intravenous β-IFN administration we treated 20 patients with histologically proven chronic hepatitis C who were nonresponders to at least two previous courses of α-IFN treatment. All patients received 6 million units (MU) of natural human fibroblast β-IFN by drip infusion, 6 times per wk for 8 wk and were followed up for 6 months after suspension of treatment. Results: Five patients (25%) …

Prospective study on thyroid autoimmunity and dysfunction related to chronic hepatitis C and interferon therapy.

1997

This study was designed to assess patients with chronic hepatitis C (CHC) for the presence of thyroid autoimmunity and dysfunction, to evaluate the risk of thyroid disorders associated with interferon (IFN) therapy, and to survey the outcome of possible treatment-related thyroid injury. Out of 104 consecutive untreated patients (30 women and 74 men; mean age, 52.7 years), 8 (7.7%) were found seropositive for thyroid autoantibodies (ThyAb), whereas seropositivity in healthy controls was 1/98 (1.3%). The relative increase in risk of developing thyroid autoimmunity associated with CHC was 760% (95% Cl, 220–1300%). No patients had abnormalities of thyroid function tests, but on IFN treatment, 3…

Perihepatic lymph nodes and antiviral response in chronic HCV-associated hepatitis.

2003

To identify predictive factors of response to interferon alpha (IFN-alpha) plus ribavirin therapy in patients with chronic hepatitis C (CHC), the presence of lymphadenopathy (LyA) of the hepatoduodenal ligament and other variables were investigated. A total of 110 patients with histologically proven CHC were enrolled in this study. Ultrasound (US) was performed at the start and end of therapy and 6 months after stopping therapy. At baseline, LyA was present in 35 (43.7%) of 80 patients with alanine aminotransferase (ALT) values and grading was significantly higher than in the LyA-negative group. LyA was more frequent in nonresponders (nonR) than in relapsers (relR) or sustained responders (…

Impact of liver steatosis on the antiviral response in the hepatitis C virus-associated chronic hepatitis.

2006

: Background/Aim: Liver steatosis (LS) has been variably associated with chronic hepatitis C (CHC) but whether it affects sustained virological response to antiviral treatment and by what mechanisms is a question still under debate, at least for some genotypes. The aim of this work was to assess the frequency of LS, its relationship with host and viral factors and to what extent it can influence the response to antiviral combination therapy with pegylated interferon (INF)+ribavirin in a group of patients with CHC from a single center. Patients: One hundred and twelve patients with histologically proven CHC were treated with Peg INF-α 2a 180 μg a week subcutaneously for 48 weeks plus ribavir…

Usefulness of alpha-fetoprotein in the diagnosis of hepatocellular carcinoma

2003

With the widespread use of ultrasonography (US) and computerized tomography (CT), the usefulness of α-fetoprotein assay in the diagnosis of hepatocellular carcinoma (HCC) has decreased. The aim of our study was to evaluate the best cut-off value for serum α-fetoprotein to discriminate between liver cirrhosis (LC) and HCC and the factors influencing levels in a Sicilian population. Three hundred and seventy-two patients with LC and 197 with HCC-associated LC were studied. The etiology was: HCV in 288 cases (77.4%) of LC and 147 cases (75%) of HCC; HBV in 31 cases (8.3%) of LC and 15 cases (7.6%) of HCC; HCV/HBV in 21 cases (5.6%) of LC and 6 cases (3.0%) of HCC; non-viral in 32 cases (8.6%) …
