[VIRTUAL] SHORT-DURATION OF DIRECT-ACTING ANTIVIRALS IN CANCER PATIENTS WITH CHRONIC HEPATITIS C VIRUS INFECTION () - Oct 11, 2020 - Abstract #AASLD2020AASLD_936; Background: Short treatment duration of direct-acting antivirals (DAAs) with an 8-week course of ledipasvir/sofosbuvir (LDV/SOF) or glecaprevir/pibrentasvir (GLE/PIB) is approved to treat chronic hepatitis C virus (HCV) infection, but data are sparse on this treatment modality in immunocompromised cancer patients. The use of short-duration of DAAs is very effective and safe in HCV-infected patients with different types of cancer.

[VIRTUAL] LONG TERM FOLLOW-UP OF SAFETY AND EFFICACY OF SOFOSBUVIR-BASED HCV DAAS IN PEDIATRIC PATIENTS () - Oct 11, 2020 - Abstract #AASLD2020AASLD_924; P=N/A Interim data are reported from a 5-year registry study (NCT02510300) in pediatric patients who received treatment for chronic hepatitis C virus (HCV) infection with sofosbuvir (SOF) +ribavirin (RBV), ledipasvir/sofosbuvir (LDV/SOF) ±RBV, or sofosbuvir/velpatasvir (SOF/VEL) in a prior clinical trial. HCV treatment with the DAAs SOF, LDV/SOF and SOF/VEL resulted in durable SVR in pediatric patients aged 3 to 17 years and did not impact growth or development through a median of 3 years and up to 5 years post-treatment.

[VIRTUAL] ACTIVE DRUG USE IS NOT ASSOCIATED WITH TREATMENT FAILURE AMONG PWID PATIENTS WITH VARIABLE ADHERENCE TO HCV TREATMENT () - Oct 11, 2020 - Abstract #AASLD2020AASLD_895; Information collected included HCV genotype, treatment regimen, use of opiate substitution therapy (OST; i.e. buprenorphine/naltrexone, methadone), active drug use (patient-reported or positive urine toxicology), adherence and SVR...The most commonly prescribed DAA regimens were: sofosbuvir-velpatasvir (N=11), sofosbuvir-ledipasvir (11 patients; 8 for 12 weeks and 3 for 8 weeks), glecaprevir-pibrentasvir for 8 weeks (N=21), elbasvir-grazoprevir (N=7) and other (N=12)... Among PWID patients who have variable adherence to HCV therapy, active drug use and maintenance on OST during treatment were not associated with treatment failure.

Journal: Sofosbuvir inhibits yellow fever virus in vitro and in patients with acute liver failure. (Pubmed Central) - Sep 30, 2020 Sofosbuvir may be used as an option for treatment against YFV until other drugs are identified and approved for human use. These results offer insights into the role of nonstructural protein 5 (NS5) in YFV inhibition and suggest that nonstructural proteins may be explored as drug targets for YFV treatment.

Clinical, Journal: Tolerability and effectiveness of generic direct-acting antiviral drugs in eradication of hepatitis C genotype 4 among Egyptian patients. (Pubmed Central) - Sep 23, 2020 The findings of this study suggest that digital medicines can be used for wirelessly observed therapy to support adherence to antiviral HCV therapy, reduce unnecessary medication wastage and retreatment costs, and potentially optimize sustained virologic response rates, especially in populations at high risk for nonadherence. Generic direct antiviral drugs used in treating Egyptian patients with HCV GT-4 demonstrated equal potency, safety and tolerability compared to original brands, with low cost which would help to provide treatment to a larger scale of patients.

[VIRTUAL] New Diagnosis of Autoimmune Hepatitis in a Patient With Remote History of SVR From DAA-Based Hepatitis C Treatment () - Sep 15, 2020 - Abstract #ACG2020ACG_2976; He was diagnosed with HCV cirrhosis, treated with 12 weeks of sofosbuvir/ledipasvir and achieved sustained virologic response (SVR)...Our patient had successfully completed treatment for HCV with DAA therapy five years before onset of AIH. We present this case not only to highlight an atypical timeline for development of HCV-induced AIH but to emphasize that providers need to maintain a high index of suspicion for AIH in patients with prior history of HCV treated with DAAs who experience subsequent liver injury.

These therapies were either given alone or in combination with ribavirin (RBV).

(Pubmed Central) - Sep 5, 2020 We briefly discuss the relationship between the pharmacokinetics of the DAAs and efficacy or toxicity in special populations, such as hard to cure patients and patients with liver cirrhosis, liver transplantation, renal impairment, hepatitis B virus or HIV co-infection, bleeding disorders, and children. The aim of this overview is to educate/update prescribers and pharmacists so that they are able to safely and effectively treat HCV-infected patients even in the presence of underlying co-infections or co-morbidities.

R30H and L31-RAS in NS5A were frequently detected after failure of regimens including daclatasvir...S282T RAS in NS5B was detected in 3.9% of ledipasvir/sofosbuvir failures...We investigated RASs after failure of various treatments for chronic hepatitis C, and found that more complicated RASs accumulated in the viral genome with successive failed treatments. The highly resistant P32del RAS at NS5A region was uniquely found in patients for whom DAA treatments had failed, and was linked to the presence and absence of specific RASs.

Journal: Low Complement C4 Predicts Improvement of Kidney Function After Direct-Acting Antiviral Therapy for Hepatitis C Virus. (Pubmed Central) - Aug 9, 2020 Patients with low baseline C4 had improved proteinuria, urinary neutrophil gelatinase-associated lipocalin, and interleukin-18 after ledipasvir and sofosbuvir treatment...Twenty patients (40%) had low baseline C4; these patients significantly improved their eGFR (+3.4 ± 11.2 mL/min/1.73 m) compared to those with normal baseline C4 (-4.4 ± 12.2 mL/min/1.73 m; P = 0.028). Low C4 may be a marker of kidney dysfunction that improves with DAA therapy.
