Safety and Effectiveness Using 8 Weeks of Glecaprevir/Pibrentasvir in HCV-Infected Treatment-Naïve Patients with Compensated Cirrhosis: The CREST Study.

Introduction: In clinical trials with hepatitis C virus-infected treatment-naïve (TN) patients with compensated cirrhosis (CC), glecaprevir/pibrentasvir (G/P), a fixed-dose, once-daily, pangenotypic regimen, has demonstrated sustained virologic response at posttreatment Week 12 (SVR12) > 95%. We evaluated the real-world safety and effectiveness of 8-week G/P therapy in TN patients with CC, including certain subgroups of interest.

Methods: The CREST study is a real-world, noninterventional, multicenter study retrospectively assessing data from Canada, Germany, Israel, Italy, and Spain.

Spontaneous clearance of chronic hepatitis C in an immunocompetent patient.

Spontaneous clearance of chronic hepatitis C virus (HCV) infection is rare and the cases described have been mainly in immunosuppressed patients (HIV). For this reason, we report the case of an immunocompetent patient diagnosed with chronic HCV infection with spontaneous clearance of the virus.

Hepatitis B virus in patients with chronic hepatitis C treated with direct antiviral agents.

Introduction: cases of hepatitis B virus (HBV) reactivation have been reported in patients with hepatitis C virus (HCV) treated with direct antiviral agents (DAA).

Objectives And Methods: the main objectives of the present study are: a) to determine the prevalence of HBV/HCV coinfection in HCV patients treated with DAAs in the Autonomous Community of Madrid (CM) and also to determine the incidence and clinical relevance of HBV reactivation; and b) to determine the HBV screening rates in HCV patients in our region. For that purpose, 1,337 HCV patients were consecutively treated with DAAs in two hospitals located in South CM between January 2015 and June 2017.

Reactivation of hepatitis B virus infection after cytotoxic chemotherapy or immunosuppressive therapy.

Reactivation of hepatitis B is defined as the recurrence or an abrupt rise in hepatitis B virus (HBV) replication, often accompanied by an increase in serum transaminase levels, and both events occurring in a patient with a previous inactive hepatitis B infection. This reactivation can occur in situations in which the ratio of HBV replication and immune response is altered. It can happen during the treatment of hemato-oncological malignancies with chemotherapy and in immunosuppression of autoimmune diseases.
