BACKGROUND AND AIMS: Patients on kidney replacement therapy (KRT) are at high risk of developing severe COVID-19 illness and often require high intensity care and utilisation of hospital resources. During the ongoing pandemic, the optimal care pathway and triage for KRT patients presenting with varying severity of COVID-19 illness is unknown. We studied clinical factors and outcomes associated with admission, readmission and short-term outcomes. METHOD: Data from the European Renal Association COVID-19 Database (ERACODA) was analysed. This database includes granular data on dialysis patients and kidney transplant recipients with COVID-19 from all over Europe. The clinical and laboratory features at first presentation of hospitalized and non-hospitalized patients and those who returned for second presentation were studied. In addition, possible predictors of outcome in those who were not hospitalized at first presentation were identified. RESULTS: Among 1,423 KRT patients (haemodialysis;1017/kidney transplant;406) with COVID-19, 25% (n=355) were not hospitalized at first presentation. Of them, only 10% (n=36), presented for a second time in the hospital. The median interval between the first and second presentation was 5 days (Interquartile interval: 2-7 days). Patients who re-presented had worsening of pulmonary symptoms, a fall in oxygen saturation (97% to 90%), and an increase in C-reactive protein (26 mg/L to 73 mg/L) between their attendances. Patients who re-presented after initial assessment were older (72 vs. 63 years) and initially more often had pulmonary symptoms and abnormalities on lung imaging compared with those who did not present for a second time. The 28-day mortality rate of patients admitted at the second presentation was similar to that of patients admitted at first presentation (26.5% vs. 29.7%, p=0. 61). Among patients who were not hospitalized at first presentation (mortality 6%), age, prior smoking, clinical frailty scale, and shortness of breath at first presentation were identified as predictors of mortality. CONCLUSION: KRT patients with COVID-19 and mild pulmonary abnormalities and no signs of pulmonary insufficiency can be safely returned without hospitalization. These patients should be advised to seek immediate contact when they develop respiratory distress. Our findings provide support for a risk-stratified clinical approach to admissions of KRT patients presenting with COVID-19. The study findings may be valuable for clinical triage and optimising hospital capacity utilisation during the ongoing pandemic.

BACKGROUND AND AIMS: The COVID-19 pandemic has serious impact on health and economics worldwide. Despite the recent advent of SARS-Cov-2 vaccines, treatment options are needed, yet pharmacologic interventions remain limited. Several extracorporeal treatments are currently explored concerning their potential to improve the clinical course and outcome of critically ill patients with COVID-19. The Seraph® 100 Microbind® Affinity adsorber (Exthera Medical, CA, USA) has recently been introduced for the elimination of several pathogens from the blood and an emergency authorization in patients with COVID-19 was granted by the FDA. Bacteria, viruses (including the SARS-CoV-2 spike glycoprotein), fungi and toxins have been shown to bind to the immobilized heparin on the ultra-high molecular weight polyethylene beads of the device in a similar way to the interaction with heparan sulfate on the cellsurface and are thereby removed from the bloodstream. Here we report the interim analysis of the COVID-19 patients treated with the Seraph® 100 Microbind® Affinity filter (COSA) registry. The goal of the registry is to gather data regarding the safety and efficacy of the Seraph® 100 in the treatment of COVID-19 patients. METHOD: Participating sites were advised to insert patient data of COVID-19 patients, treated with the Seraph® 100, during their hospital stay into the COSA registry ( Identifier: NCT04361500). A total of 66 items were asked in a web-based platform. RESULTS: Until January 2021, 33 patients with 39 treatment sessions form six different hospitals were reported to the register (seven female, median age 61 years, Table 1). The patients were treated between March and December 2020. Eleven patients with a hospital admission between March and August and 22 between September and December 2020. The Seraph® 100 treatment was initiated 9 days after symptom onset, without any difference between survivors and non-survivors. Overall, a mortality of 27% was reported. Serious comorbidities (as preadmission immunosuppressive therapy, lung fibrosis or CKD5T) were reported in all of the nonsurvivors. Invasive ventilation was needed in 67% of these patients when Seraph treatment was initiated. A non-significant trend towards higher Ferritin levels in nonsurvivors (2000 (1963 - 8326) vs. 989 (644 - 2000), p=0.09) was reported. All treatments were well tolerated, three clotting events were reported. CONCLUSION: Viral SARS-CoV-2 RNA is frequently (up to 78%) seen in the blood of critically ill COVID-19 patients and correlates with the severity of the disease. The Seraph® 100 can bind to viral spike protein, proinflammatory cytokines may be reduced by the device and hemodynamic stabilization has been reported during the Seraph® 100 treatment of COVID-19 patients. Platelets can be hyperactivated in association with SARS-CoV-2 proteins and thus presumably trigger the hypercoagulation and thrombosis. In this context, the removal of SARS-CoV-2 proteins to prevent hyperactivated platelets appears to be a sensible approach. All reported deaths were associated with serious preexisting comorbidities, immunosuppression, dialysis dependent renal failure, or a combination of these factors. Hence, Seraph® 100 treatment may be most beneficial in COVID-19 courses of patients without multi organ failure. More clinical data is needed to describe possible benefits of the Seraph® 100 in the treatment of COVID-19 patients. (Table Presented).
