Effects of IL28B rs12979860 CC Genotype on Metabolic Profile and Sustained Virologic Response in Patients With Genotype 1 Chronic Hepatitis C
2013
Patients with genotype 1 chronic hepatitis C (G1 CHC) frequently develop steatosis and insulin resistance (IR), caused by metabolic and viral factors. These accelerate the progression of liver disease and reduce the response to therapy. A sustained virologic response (SVR) to therapy in patients with G1 CHC is associated strongly with polymorphisms near the interleukin-28B (IL28B) gene, but the interaction between IL28B genotype and IR, and their combined effects on SVR, have not been defined. We tested the association between the IL28B rs12979860 single-nucleotide polymorphism and metabolic features, including IR, and evaluated their effects on SVR.We performed genotype analysis of IL28B r…
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%) …
Hepatitis C virus RNA profiles in chronically infected individuals: do they relate to disease activity?
1999
Fluctuations of hepatitis C virus (HCV)-RNA serum levels were monitored in a multicenter study in 76 chronic HCV carriers who had been followed longitudinally without receiving antiviral therapy to assess their relation with the course of liver disease activity. Forty-four patients had normal transaminases over more than 2 years, while 32 additional patients had fluctuating levels. Viral load was measured in serial serum samples prospectively collected for 10 to 12 months in 54 patients and in sera stored yearly up to 8 years in an additional 22 patients. In patients tested monthly, a lesser extent of fluctuations was detected in cases with constantly normal transaminases as compared with t…
Role of a 48-week pegylated interferon therapy in hepatitis B e antigen positive HIV-co-infected patients on cART including tenofovir: EMVIPEG study.
2014
In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed.A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72).Fifty-one patients (49 men, median age 46 years, range: 32-6…
Pegylated alpha-interferon-2a plus ribavirin compared with pegylated alpha-interferon-2b plus ribavirin for initial treatment of chronic hepatitis C …
2008
Background and aim We assessed whether the two regimens of pegylated alpha-interferon-2b (PEG-IFN-alpha2b) plus ribavirin and pegylated alpha-interferon-2a (PEG-IFN-alpha2a) plus ribavirin showed differences in terms of sustained virological response, withdrawal due to side-effects and dose adjustment requirements in the treatment of naive chronic hepatitis C virus (HCV) patients. Methods A prospective non-randomized, open-label comparison was made of naive HCV-infected patients undergoing standard 24- or 48-week treatment with two PEG-IFN combined with weight-based dosing regimen of ribavirin (PEG-IFN-alpha2a/ribavirin, n = 91; PEG-IFN-alpha2b/ribavirin, n = 92). Results Sustained virologi…
Virological efficacy and emergence of drug resistance in adults on antiretroviral treatment in rural Tanzania
2009
Background Virological response to antiretroviral treatment (ART) in rural Africa is poorly described. We examined virological efficacy and emergence of drug resistance in adults receiving first-line ART for up to 4 years in rural Tanzania. Methods Haydom Lutheran Hospital has provided ART to HIV-infected patients since October 2003. A combination of stavudine or zidovudine with lamivudine and either nevirapine or efavirenz is the standard first-line regimen. Nested in a longitudinal cohort study of patients consecutively starting ART, we carried out a cross-sectional virological efficacy survey between November 2007 and June 2008. HIV viral load was measured in all adults who had completed…
Monitoring of alphatorquevirus DNA levels for the prediction of immunosuppression-related complications after kidney transplantation
2019
The replication kinetics of nonpathogenic anelloviruses belonging to the Alphatorquevirus genus (such as torque teno virus) might reflect the overall state of posttransplant immunosuppression. We analyzed 221 kidney transplant (KT) recipients in whom plasma alphatorquevirus DNA load was quantified by real-time polymerase chain reaction at baseline and regularly through the first 12 posttransplant months. Study outcomes included posttransplant infection and a composite of opportunistic infection and/or de novo malignancy (immunosuppression-related adverse event [iRAE]). Alphatorquevirus DNA loads at month 1 were higher among patients who subsequently developed posttransplant infection (P = …
Different doses of consensus interferon plus ribavirin in patients with hepatitis C virus genotype 1 relapsed after interferon monotherapy: a randomi…
2006
AIM: To assess the efficacy of different schedules of consensus interferon (CIFN) plus ribavirin in retreating chronic hepatitis C patients who relapsed after recombinant interferon (rIFN) monotherapy. METHODS: Forty-five patients (34 males and 11 females) with chronic hepatitis due to hepatitis C virus (HCV) genotype 1 who relapsed after a previous course of rIFN monotherapy were randomized to receive 9 μg CIFN three times per week for 52 wk (group A, n = 22) or 18 μg CIFN three times per week for 52 wk (group B, n = 23) in combination with ribavirin 800 to 1200 mg daily for 52 wk (according to body weight). Virological response was evaluated at week 24 (EVR), at the end of treatment (ETR)…
Gender differences in human immunodeficiency virus–related oral lesions: An Italian study
2001
Abstract Objective: The purpose of this study was to investigate the relationship between oral lesions and gender, age, CD4+ cell count, human immunodeficiency virus-1 (HIV-1) viral load, antiretroviral therapy, and route of transmission in a group of HIV-infected (HIV+) persons from the Mediterranean region. Study Design: The participants in this study were HIV+ adults who sought dental care between January 1999 and June 1999 in the Department of Oral Medicine (University of Palermo, Italy). Results: One hundred thirty-six HIV+ adults came in for an initial oral examination. Their mean age was 35.2 years (SD ± 7.97), and 33% were women. Their mean CD4+ cell count was 325.3 × 106 /L (SD ± 2…
Consensus interferon and ribavirin for patients with chronic hepatitis C and failure of previous interferon-alpha therapy.
2006
BACKGROUND The efficacy of consensus interferon (CIFN), a synthetic IFN with optimised in vitro activity, was assessed in chronic hepatitis C virus (HCV) patients who had failed the pretreatment with interferon-alpha (IFNalpha) and ribavirin. METHODS One hundred and three patients after non-response (n=69) or relapse (n=34) to IFNalpha+/-ribavirin were randomly assigned to high-dose induction (CIFN 27-->9 microg daily for 24 weeks, 9 microg t.i.w. for 24 weeks) or low-dose treatment (CIFN 18 microg t.i.w. for 12 weeks, 9 microg t.i.w. for 36 weeks); each with ribavirin 800 mg/day. Follow-up was 24 weeks. RESULTS Non-responder patients treated with high-dose induction had higher early virolo…
