Aims: SARS-CoV-2 causes systemic immune dysfunction, leading to severe respiratory dysfunction and multiorgan dysfunction. Granulocyte and monocyte adsorptive apheresis (GMA) therapy is designed to regulate an excessive inflammatory response and has been proposed as a potential therapeutic strategy for coronavirus disease 2019 (COVID-19). We aimed to investigate a targeted subset of granulocytes and monocytes to be removed after GMA therapy in patients with severe COVID-19 infection.

Methods: We established an ex vivo experimental system to study the effects of GMA. Blood samples were collected into EDTA-treated tubes and a mixture of blood samples and cellulose acetate beads was used in GMA. After GMA, blood samples were removed, and the granulocyte and monocyte subtypes before and after GMA were determined by CyTOF mass cytometry. To analyze mass cytometry data with a self-organizing map, hierarchical clustering was used to determine the appropriate number of metaclusters from t-distributed stochastic neighbor embedding.

Results: We included seven patients with severe COVID-19 and four age- and sex-matched volunteers. Granulocyte subsets removed by GMA strongly expressed CD11b, CD16, and CD66b, and weakly expressed CD11c, consistent with mature and activated neutrophils. Monocyte subsets strongly expressed CD14, weakly expressed CD33 and CD45RO, and did not express CD16. These subsets were indicated to promote the release of inflammatory cytokines and activate T cells.

Conclusions: The identification of the granulocyte and monocyte subsets removed after GMA in patients with severe COVID-19 may help explain the potential mechanism underlying the effectiveness of GMA in COVID-19 and other inflammatory diseases.

Multisystem inflammatory syndrome in adults (MIS-A) is a life-threatening disease that can develop weeks after coronavirus disease 2019 (COVID-19). MIS-A symptoms include multiorgan involvement, especially gastrointestinal tract and heart involvement, and Kawasaki disease-like symptoms. We herein report a 44-year-old Japanese man with MIS-A who had contracted COVID-19 five weeks ago and went into shock after acute gastroenteritis, acute kidney injury, and Kawasaki disease-like symptoms. Methylprednisone pulse and high-dose intravenous immunoglobulin resulted in recovery of shock and his renal function, but diffuse ST-segment elevation on electrocardiography and pericardial effusion with a fever emerged after therapy. Additional granulocyte-monocyte adsorptive apheresis successfully ameliorated the cardiac involvement.

Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Accumulating evidence suggests that the severity of COVID-19 is due to high levels of circulating inflammatory mediators including cytokines and chemokines leading to cytokine storm syndrome (CSS). Patients are admitted in ICU with severe respiratory failure, but can also develop acute renal failure and multi organ failure. Advances in science and technology have permitted the development of more sophisticated therapies such as hemoperfusion, and various blood purification devices, for the treatment of ARDS and septic shock. Adsorptive granulocyte and monocyte apheresis (GMA) is an extracorporeal circulation therapy designed for selective absorption of elevated and activated myeloid lineage cells, inducing immunomodulartory effects with decrease of inflammatory cytokines. It has been shown efficacy in inflammatory bowel disease and psoriatic arthritis. In Covid-19 it has been used in one case report in a patient having comorbidity ulcerative colitis. Apart from the control of the colitis there was an unexpected improvement of the pulmonary symptoms and the septic shocK.

Coronavirus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is now a pandemic. Although several treatment guidelines have been proposed for patients who have both inflammatory bowel disease and COVID-19, immunosuppressive therapy is essentially not recommended, and the treatment options are limited. Even in the COVID-19 pandemic, adjuvant adsorptive granulocyte and monocyte apheresis may safely bring ulcerative colitis (UC) into remission by removing activated myeloid cells without the use of immunosuppressive therapy. Our patient was a 25-year-old Japanese male with UC and COVID-19. This is the first case report of the induction of UC remission with granulocyte and monocyte apheresis treatment for active UC associated with COVID-19.

In conclusion, our patient’s case indicates that GMA for a patient with both active UC and COVID-19 is a safe treatment option for active UC that could lead other patients in this condition to remission.

To our knowledge, GMA has a good safety profile; serious adverse effects are rarely reported. Its modes of action together with the findings of this case report support our notion that GMA is a relevant therapeutic option for patients with COVID-19 and warrants an immediate clinical trial to evaluate its full therapeutic efficacy in a large cohort of COVID-19 patients.
