Immunocompromised patients still experience unpredictable courses of COVID-19, despite that effective vaccines and drugs against SARS-CoV-2 are now available. Antiviral combination regimens may have a role in SARS-CoV-2 infection in immunocompromised hosts, but current knowledge is still limited. We describe the case of a 73-year-old Italian man affected by follicular lymphoma with persistent SARS-CoV-2 infection who was successfully treated with co-administration of oral antivirals (10-day molnupiravir and nirmatrelvir/ritonavir). The therapy was well tolerated both from a clinical and biochemical standpoint, with no signs of toxicity. We also performed a scoping review, to sum up available knowledge on combined antiviral regimens including remdesivir, molnupiravir, or nirmatrelvir/ritonavir. Pending further studies on larger cohorts of patients, our report is consistent with available pre-clinical and clinical data, supporting the possible use of combination therapy in selected difficult-to-treat COVID-19 cases.
