Abstract
There is an urgent need for therapeutic interventions to alter the course of critically ill coronavirus disease 2019 (CO-VID-19) patients. We report our experience with the Seraph-100 Microbind Affinity Blood Filter (Seraph-100) in 4 patients with COVID-19 early in the course of their critical respiratory illnesses. Patients were diagnosed with COVID-19 and were admitted to intensive care with worsening respiratory failure but did not require dialysis or vasopressors. Patients had to have a PaO2 to FiO2 (P/F ratio) <150 to qualify for hemoperfusion therapy. All patients received standard medical therapy including oral vitamins C and D and zinc in addition to intravenous dexamethasone and remdesivir. Patients received a single 5- to 7-h session with Seraph-100 on a conventional dialysis machine (Fresenius 2008T) via a nontunneled central venous dialysis catheter with a goal of processing at least 100 L of blood. Patients received weight-based subcutaneous enoxaparin anticoagulation, as well as systemic intravenous heparin (70 units/kg), just prior to hemofiltration. Treatment with Seraph-100 hemoperfusion was well tolerated, and all patients were able to finish their prescribed therapy. All patients treated with Seraph-100 survived to be discharged from the hospital. Well-designed clinical trials are needed to determine the overall safety and efficacy of the Seraph-100 Microbind Affinity Blood Filter in COVID-19 patients.
