1. Ribavirin for treating Crimean Congo haemorrhagic fever. (PubMed)

Ribavirin for treating Crimean Congo haemorrhagic fever. Crimean Congo haemorrhagic fever (CCHF) is a tick-borne disease that occurs in parts of Asia, Europe and Africa. Since 2000 the infection has caused epidemics in Turkey, Iran, Russia, Uganda and Pakistan. Good-quality general supportive medical care helps reduce mortality. There is uncertainty and controversy about treating CCHF with the antiviral drug ribavirin.To assess the effects of ribavirin for treating people with Crimean Congo (...) in the field and obtained further studies from these sources.We evaluated studies assessing the use of ribavirin in people with suspected or confirmed Crimean Congo haemorrhagic fever. We included randomised control trials (RCTs); non-randomised studies (NRSs) that included more than 10 participants designed as cohort studies with comparators; and case-control studies.Two review authors assessed eligibility, risk of bias, and extracted data. For non-randomized studies we used the ROBINS-I tool to assess

2. Ribavirin Dose Management in HCV Patients Receiving Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir with Ribavirin. (PubMed)

Ribavirin Dose Management in HCV Patients Receiving Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir with Ribavirin. Some individuals with hepatitis C virus infection treated with direct-acting antivirals require ribavirin to maximize sustained virological response rates. We describe the clinical management of ribavirin dosing in hepatitis C virus-infected patients receiving ombitasvir/paritaprevir/ritonavir and dasabuvir with ribavirin.We performed a post hoc analysis of patients receiving (...) ombitasvir/paritaprevir/ritonavir and dasabuvir with ribavirin for 12 or 24 weeks in six phase 3 trials. Multivariate stepwise logistic regression models assessed predictors associated with ribavirin dose adjustments and with developing anaemia.Of 1548 patients, 100 (6.5%) modified ribavirin dose due to haemoglobin declines, of which 99% achieved sustained virological response at 12 weeks post-treatment. Median time to first ribavirin dose reduction was 37 days. Low baseline haemoglobin was significantly

6. ITPA polymorphism correlates with the reductions in hemoglobin concentration and ribavirin dose during sofosbuvir and ribavirin therapy. (PubMed)

ITPA polymorphism correlates with the reductions in hemoglobin concentration and ribavirin dose during sofosbuvir and ribavirin therapy. It is unclear whether polymorphism in the inosine triphosphatase (ITPA) gene correlates to the reduction in hemoglobin (Hb) concentrations during sofosbuvir (SOF) and ribavirin (RBV) therapy. This study investigated the effects of the ITPA polymorphism on Japanese patients with chronic hepatitis C virus genotype 2 infection treated with SOF/RBV therapy.In 106

8. Ribavirin in Acute Hepatitis E Infection in Patients with Gynecological Cancer: A Case Series (PubMed)

Ribavirin in Acute Hepatitis E Infection in Patients with Gynecological Cancer: A Case Series Hepatitis E virus infection is usually a self-limited disease. However, during the last years there has been growing evidence for prolonged and chronic infection occurring in patients with immunosuppression. Also patients with malignant and rheumatic diseases have been identified to be at risk for chronic hepatitis E. However, their course and prognosis are not well characterized and there have been (...) , the third patient with a high-risk oncological constellation required ribavirin in order to resume chemotherapy. These cases highlight the need for hepatitis E virus testing in patients with gynecological cancer and elevated aminotransferase levels. Further, these cases show that in selected high-risk patients, ribavirin treatment may be necessary based on the decision of a multidisciplinary team.

Randomized Trial Evaluating the Impact of Ribavirin Mono-Therapy and Double Dosing on Viral Kinetics, Ribavirin Pharmacokinetics and Anemia in Hepatitis C Virus Genotype 1 Infection. In this pilot study (RibaC), 58 hepatitis C virus (HCV) genotype 1 infected treatment-naïve patients were randomized to (i) 2 weeks ribavirin double dosing concomitant with pegylated interferon-α (pegIFN-α), (ii) 4 weeks ribavirin mono-therapy prior to adding pegIFN-α, or (iii) standard-of-care (SOC) ribavirin (...) dosing concurrent with pegIFN-α. Four weeks of ribavirin mono-therapy resulted in a mean 0.46 log(10) IU/mL HCV RNA reduction differentially regulated across IL28B genotypes (0.89 vs. 0.21 log(10) IU/mL for CC and CT/TT respectively; P = 0.006), increased likelihood of undetectable HCV RNA week 4 after initiating pegIFN-α and thus shortened treatment duration (P<0.05), and decreased median IP-10 concentration from 550 to 345 pg/mL (P<0.001).

17. Hepatitis E virus mutations associated with ribavirin treatment failure result in altered viral fitness and ribavirin sensitivity. (PubMed)

Hepatitis E virus mutations associated with ribavirin treatment failure result in altered viral fitness and ribavirin sensitivity. Ribavirin monotherapy is the preferred treatment for chronic hepatitis E, although occasional treatment failure occurs. We present a patient with chronic hepatitis E experiencing ribavirin treatment failure with a completely resistant phenotype. We aimed to identify viral mutations associated with treatment failure and explore the underlying mechanisms.Viral genomes (...) for Y1320H and G1634R mutations and the hypervariable region insertion. In contrast, the K1383N mutation in the polymerase F1-motif suppressed viral replication and increased the in vitro sensitivity to ribavirin, contrary to the clinical phenotype. Analysis of the replication of mutant full-length virus and in vitro culturing of patient-derived virus confirmed that sensitivity to ribavirin was retained. Finally, deep-sequencing of hepatitis E virus genomes revealed that ribavirin is mutagenic to viral
