Abstract
Background: Viremia has been detected in a significant proportion of patients with acute respiratory viral infection, yet its clinical value remains underappreciated.
Objectives: This study synthesized available evidence to comprehensively assess the prevalence of viremia and its impact on clinical outcomes.
Methods: Data sources: Data were retrieved from Medline (via Ovid), Embase, and the WHO COVID-19 database.
Study eligibility criteria: This review included original clinical studies analysing the prevalence of viremia in patients with acute respiratory viral infection or its association with clinical outcomes, while excluding non-original research, insufficiently detailed studies, inconsistent pathogen observations, or those with inadequate sample sizes.
Participants: Patients with acute respiratory viral infection.
Assessment of risk of bias: Newcastle-Ottawa scale and an adapted version were used.
Methods of data synthesis: Data synthesis utilized random-effects models to pool prevalence and hazard ratio (HR), OR, and adjusted HR/OR for clinical outcomes.
Results: In the comprehensive analysis of viremia prevalence, data were pooled from 101 studies, which included a total of 16,388 non-overlapping patients. Viremia was present in 34% (95% CI, 28-41%) of patients with acute respiratory viral infection. A total of 45 studies provided information on the clinical outcomes of 2002 patients with viremia and 3907 patients without viremia. Viremia was associated with increased risks of mortality (OR, 6.83; 95% CI, 4.92-9.48; adjusted HR, 2.91; 95% CI, 1.87-4.53; adjusted OR, 3.68; 95% CI, 2.37-5.71), intensive care unit admission (OR, 4.74; 95% CI, 2.66-8.46; adjusted OR, 4.89; 95% CI, 1.61-14.91), mechanical ventilation (OR, 4.12; 95% CI, 2.25-7.52), and hepatic complications (OR, 3.10; 95% CI, 1.30-7.40).
Conclusions: Viremia is prevalent in patients with respiratory viral infection and is associated with elevated risks of adverse clinical outcomes.
期刊介绍：
Clinical Microbiology and Infection (CMI) is a monthly journal published by the European Society of Clinical Microbiology and Infectious Diseases. It focuses on peer-reviewed papers covering basic and applied research in microbiology, infectious diseases, virology, parasitology, immunology, and epidemiology as they relate to therapy and diagnostics.
