| Summary: | Abstract Background & aim The impact of Omicron variants on cirrhosis was largely unknown. Herein, we aimed to evaluate the impact of SARS-CoV-2 omicron variants infection on the clinical course and mortality of patients with liver cirrhosis. Methods Between 26 December 2022, and 27 January 2023, eighty-two hospitalized patients with cirrhosis and confirmed SARS-CoV-2 infection were enrolled. The clinical and pulmonary CT imaging features were retrospectively collected. A gender and age-matched cohort of 51 non-cirrhotic patients with COVID-19 were also included. Results Our results indicated the symptom heterogeneity in patients with cirrhosis infected with omicron variants. Patients with more severe liver disease tended to have less severe respiratory symptoms and less pulmonary lesions. SARS-CoV-2 omicron did not cause obvious perturbation of liver function or cirrhosis decompensation. In comparison with hospitalized COVID-19 patients without liver cirrhosis, cirrhotic patients showed more severe pulmonary lesions and higher levels of inflammatory cytokine IL-6, but no significant increase in mortality. Multivariate analysis identified lung lesions proportion, MELD ≥ 15 score, and APTT as independent predictors for 28-day-mortality in these patients. Conclusion SARS-CoV-2 omicron variants caused a more severe inflammatory response in cirrhotic patients than in non-cirrhotic patients, but no further deterioration of liver function. Instead, patients with advanced stage of liver cirrhosis showed milder respiratory symptoms and pulmonary lesions. These results underscore the intricate relationship between Omicron infection and cirrhosis, highlighting the necessity for personalized clinical approaches in managing this specific patient group. |
