Umbilical Cord Blood Mononuclear Cell Treatment for Neonatal Rats With Hypoxic Ischemia.

Background: Hypoxic-ischemic encephalopathy (HIE) occurs when an infant's brain has not received adequate oxygen and blood supply, resulting in ischemic and hypoxic damage. Currently, supportive care and hypothermia therapy have been the standard treatment for HIE. However, there are still over 20% of treated infants died and 19-30% survived with significant disability.

Interleukin-28B rs12979860 C allele: Protective against advanced fibrosis in chronic hepatitis C genotype 1 infection.

Background and Aim: While genetic polymorphisms upstream of the interleukin-28B(IL28B) gene are associated with necroinflammatory activity grade in chronic hepatitis C virus genotype 1 (HCV-1) infection, any association with fibrosis is less definitive. Pretreatment liver biopsies in a cohort of treatment-naïve patients with HCV-1 were analyzed to evaluate associations between liver histology, and the rs12979860 and rs8099917 IL28B single nucleotide polymorphisms.Methods: Two hundred sixty-six patients with HCV-1 infection and pretreatment liver biopsy were tested for the rs12979860 and rs8099917 single nucleotide polymorphisms.

ITPA genotype protects against anemia during peginterferon and ribavirin therapy but does not influence virological response.

Unlabelled: On-treatment anemia is associated with higher sustained virological response (SVR) rates during peginterferon plus ribavirin (RBV) therapy. Inosine triphosphatase (ITPA) variants causing ITPase deficiency have been shown to protect against RBV-induced anemia. However, ITPase activity has not been associated with SVR.

Successful treatment of patients with hepatitis C in rural and remote Western Australia via telehealth.

Rural and remote patients at the Royal Perth Hospital were reviewed and treated for hepatitis C by a hepatologist and nurse practitioner using telehealth (videoconferencing). Over a four-year period, 50 patients were treated with pegylated interferon and ribavirin, and participated in a total of more than 500 telehealth sessions. Sustained virological response rates (SVRs) were compared to those in face-to-face (FTF) clinics to assess treatment outcomes.

Vitamin D status does not predict sustained virologic response or fibrosis stage in chronic hepatitis C genotype 1 infection.

Background & Aims: The relationship between vitamin D status and response to antiviral therapy and liver histology in hepatitis C virus genotype 1 (HCV-1) infection remains unclear, with studies to date yielding inconsistent results and failing to use reference assay methodology. We therefore analyzed pre-treatment 25-hydroxyvitamin D [25(OH)D] level, using reference liquid chromatography-tandem mass spectrometry methodology, in a cohort of treatment-naïve patients with HCV-1 to evaluate the association between vitamin D status, virologic response, and liver histology.

Methods: 274 patients, with pre-treatment liver biopsy and up to 48 weeks of pegylated interferon alfa-2a plus ribavirin therapy, were tested for serum 25(OH)D level.

Early on-treatment viral load and baseline METAVIR score: improved prediction of sustained virological response in HCV genotype 1 patients.

Background: On-treatment HCV viral load during early therapy with pegylated interferon (PEG-IFN) and ribavirin is highly predictive of sustained virological response (SVR). We sought to provide further refinement of this prediction through an extensive evaluation of the effect of HCV viral loads at weeks 4, 8 and 12 on SVR, including analysis by liver disease stage grouping.

Methods: A total of 309 patients with genotype 1 chronic HCV and recent liver biopsy enrolled in the CHARIOT study received 180 μg of PEG-IFN-α2a weekly with 1,000/1,200 mg of ribavirin daily.

Low virological response and high relapse rates in hepatitis C genotype 1 patients with advanced fibrosis despite adequate therapeutic dosing.

Background & Aims: The impact of fibrosis stage on chronic hepatitis C virus (HCV) treatment response was explored in CHARIOT, a study of high dose peginterferon alfa-2a (PEG-IFNalpha-2a) induction therapy in treatment naïve genotype 1 infection.

Methods: Eight hundred and ninety-six patients were randomised 1:1 to 360 microg (n=448) or 180 microg (n=448) PEG-IFNalpha-2a weekly with RBV 1000-1200 mg/day for 12 weeks followed by 36 weeks of 180 microg PEG-IFNalpha-2a weekly plus RBV 1000-1200 mg/day. Virological responses were assessed at week 4, 8, 12, 24, 48 (end of therapy), and 24 weeks following therapy (sustained virological response, SVR).

Impact of high-dose peginterferon alfa-2A on virological response rates in patients with hepatitis C genotype 1: a randomized controlled trial.

Unlabelled: This study tested the hypothesis that high-dose peginterferon alfa-2a (PEG-IFNalpha-2a) for the first 12 weeks would increase early and sustained virological response (SVR) rates in patients with chronic hepatitis C genotype 1. Eight hundred ninety-six patients were randomized 1:1 to 360 microg (n = 448) or 180 microg (n = 448) PEG-IFNalpha-2a weekly plus ribavirin at 1000-1200 mg/day for 12 weeks, followed by 36 weeks of 180 microg PEG-IFNalpha-2a weekly plus ribavirin at 1000-1200 mg/day with 871 patients evaluable for the intention-to-treat analysis. Virological responses were assessed by TaqMan (limit of detection 15 IU/mL) at week 4, 8, 12, 24, 48 (end of therapy), and 24 weeks following therapy (SVR).
