Human pegivirus infection after transplant:Is there an impact?

摘要

The microbiome's role in transplantation has received growing interest,but the role of virome remains understudied.Pegiviruses are single-stranded positivesense RNA viruses,historically associated with liver disease,but their pathogenicity is controversial.In the transplantation setting,pegivirus infection does not seem to have a negative impact on the outcomes of solid-organ and hematopoietic stem cell transplant recipients.However,the role of pegiviruses as proxies in immunosuppression monitoring brings novelty to the field of virome research in immunocompromised individuals.The possible immunomodulatory effect of pegivirus infections remains to be elucidated in further trials.
