Background: Sepsis remains a global health burden associated with significant morbidity and mortality. Bacteria are known to be the predominant pathogens in sepsis; however, viral etiologies in sepsis are still under diagnosed. Respiratory viral pathogens have been previously linked to sepsis, but the knowledge of incidence, disease burden and mortality of viral-induced sepsis remains limited. This study aimed at understanding the role of respiratory viral infections in the causation of sepsis in liver disease patients.
Methods: In this retrospective study, the clinical records of liver disease patients with influenza-like illness, whose requests for respiratory viral testing were received from January 2019 to December 2022, were reviewed. Respiratory viruses were identified using FilmArray 2.0 respiratory panel (BioFire Diagnostics, Utah, USA).
Results: Of 1391 patients tested, a respiratory viral etiology was detected in 23%. The occurrence of sepsis was seen in 35%. Among these, isolated viral etiology with no other bacterial/fungal coinfection was found in 55% of patients. Rhinovirus/Enterovirus was found as the most common underlying viral etiology (23.4%). The sepsis prevalence was higher among patients with associated comorbidities (45%) and decompensated cirrhosis (84%). On multi-variable analysis, no factor was found independently associated with sepsis-related mortality.
Conclusion: This study underlines the importance of isolated viral etiology in causation of sepsis among liver disease patients. Patients with comorbidities, older age and decompensated cirrhosis are at an increased risk of developing sepsis and are associated with poorer outcomes. Accurate and timely identification of the viral etiology in sepsis would prevent the misuse of antibiotics and improve overall patient care.
