Humoral and T-cell-mediated immunity to SARS-CoV-2 vaccination in patients with liver disease and transplant recipients.

Background: SARS-CoV-2 vaccination induces a varied immune response among persons with chronic liver disease (CLD) and solid organ transplant recipients (SOTRs). We aimed to evaluate the humoral and T-cell-mediated immune responses to SARS-CoV-2 vaccination in these groups.

Methods: Blood samples were collected following the completion of a standard SARS-CoV-2 vaccination (2 doses of either BNT162b2 or mRNA-12732), and a subset of patients had a blood sample collected after a single mRNA booster vaccine.

Hepatitis C and HIV co-infection: new drugs in practice and in the pipeline.

HCV/HIV coinfection continues to represent a serious health issue with risk of liver disease progression and development of hepatocellular carcinoma. Pegylated interferon with ribavirin is approved for treatment but results are suboptimal and tolerability poor. First-generation HCV protease inhibitors appear to significantly improve HCV treatment response in the setting of HIV infection.
