Clinical Characteristics and Outcomes in Patients with Chronic HBV Infection and Hospitalized for COVID-19 Pneumonia: A Retrospective Cohort Study.

The effects of a concomitant infection of hepatitis B virus (HBV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are still debated, with a recognized major risk of HBV reactivation during immune-suppressive treatments. The aim of this study was to determine the prevalence and predictive factors of HBV reactivation in a cohort of hospitalized patients with coronavirus disease 2019 (COVID-19) and a current or past hepatitis B infection. In a monocentric retrospective observational study, we enrolled all consecutive hospital admitted patients with COVID-19 pneumonia and a positive HBV serology (N = 84) in our Infectious Diseases Unit from April 2021 to December 2023.

Due to the lack of agents that directly target covalently closed circular DNA and integrated HBV DNA in hepatocytes, achieving a complete cure for chronic hepatitis B (CHB) remains challenging. The latest guidelines recommend (hepatitis B surface antigen) HBsAg loss as the ideal treatment target for improving liver function, histopathology, and long-term prognosis. However, even after HBsAg loss, hepatitis B virus can persist, with a risk of recurrence, reactivation, cirrhosis, and hepatocellular carcinoma.

Hepatitis B virus (HBV) is a major global health issue, with an estimated 254 million people living with chronic HBV infection worldwide as of 2022. Chronic HBV infection is the leading cause of cirrhosis and liver cancer. Current treatment with nucleos(t)ide analogs is effective in the suppression of viral activity but generally requires lifelong treatment.

Acetylcholinesterase inhibition, the principal mechanism of acute organophosphorus compound toxicity, cannot explain neuropsychiatric symptoms occurring after exposure to low organophosphate concentrations causing no cholinergic symptoms. Organophosphate-triggered oxidative stress has increasingly come into focus, occurring when the action of reactive oxygen species, generated from free radicals, is not compensated by antioxidant free radical scavengers. Being nucleophilic, organophosphates can easily accept an electron, thereby generating free radicals.

Cancer patients receiving non-endocrine therapies are at risk of hepatitis B virus (HBV) reactivation (HBVr). Guidelines recommend HBV screening prior to treatment. The Ottawa Hospital Cancer Center implemented a screening pilot for all patients receiving FOLFOX-based regimens between January and April 2023.
