Salamanca researchers study serious respiratory diseases

Researchers from the Institute of Biomedical Research of Salamanca (IBSAL), the University of Salamanca (USAL) and the Respiratory Diseases Unit of the Network Biomedical Research Center (CIBER) conducted a systematic review for the presence of viremia – the spread of viral components. from the lungs into the blood – in patients with severe respiratory infections, contrary to what was believed until now, found a high prevalence and direct association with disease severity, with important pathophysiological and clinical consequences in SARS-CoV-2 infection in the short and long term, and very likely also in infections caused by other respiratory viruses.

The importance of the study, published in the world’s premier microbiology journal The Lancet Microbe, is that it represents a world-first review of the presence of viremia in infections other than Covid-19. caused by other coronaviruses, adenoviruses, rhinoviruses, respiratory syncytial virus and influenza. On the other hand, since These findings pave the way for the development of additional studies examining the role of monitoring, preventing, or eliminating this viral load in the blood to improve detection, treatment, prognosis, and long-term complications in patients with severe respiratory infection.

Except, These results also suggest the need to better understand the role of viremia in the pathogenesis of long-term extrapulmonary diseases such as diabetes or autoimmune pathologies.
