Successful Repeated Use of a Pathogen Adsorbing Biomimetic Device for the Adjunct Treatment of a SARS-CoV-2 Reinfection and Subsequent Infections with Different Multiresistant Bacteria.

Introduction: The Seraph 100 Microbind Affinity Filter is a biomimetic adsorbent device that can remove pathogens from the blood.

Case Presentation: Here, we report the successful use of the Seraph 100 to treat both a SARS-CoV-2 reinfection leading to severe COVID-19 pneumonia as well as subsequent secondary lung infections including Acinetobacter baumannii, Serratia marcescens, and Pseudomonas aeruginosa multidrug-resistant bacteria. To our knowledge, this 46-year-old black male is the first patient in which four treatments with this pathogen adsorber, one for a viral and three for different bacterial infections, have been successfully used.

Conclusion: The Seraph 100 can be easily and successfully used in conjunction with standard (anti-infective) treatment.
