Case Report: Successful Treatment With Monoclonal Antibodies in One APDS Patient With Prolonged SARS-CoV-2 Infection Not Responsive to Previous Lines of Treatment

We described the case of a patient affected by activated PI3K-kinase delta syndrome (APDS) and a long-lasting and pauci-symptomatic SARS-CoV-2 infection, treated with multiple therapeutic agents including remdesivir and SARS-CoV-2-neutralizing monoclonal antibodies. We detected the clearance of the virus 105 days from the first positive swab and 7 days after monoclonal antibody administration. At genotyping, the SARS-CoV-2 virus resulted as wild type on all samples tested. This case shows the monoclonal antibodies' good tolerability and efficacy in reducing viral shedding in long-lasting infections refractory to other treatments.

Automated summary

This case demonstrates the good tolerability and efficacy of monoclonal antibodies in reducing viral shedding in long-lasting infections refractory to other treatments. The virus was cleared 7 days after monoclonal antibody administration, showing the effectiveness of this treatment option.
