ABSTRACT

BACKGROUND: Anti-SARS-CoV-2 S antibodies prevent viral replication. Critically ill COVID-19 patients show viral material in plasma, associated with a dysregulated host response. If these antibodies influence survival and viral dissemination in ICU-COVID patients is unknown. PATIENTS/METHODS: We studied the impact of anti-SARS-CoV-2 S antibodies levels on survival, viral RNA-load in plasma, and N-antigenaemia in 92 COVID-19 patients over ICU admission. RESULTS: Frequency of N-antigenaemia was >2.5-fold higher in absence of antibodies. Antibodies correlated inversely with viral RNA-load in plasma, representing a protective factor against mortality (adjusted HR [CI 95%], p): (S IgM [AUC ≥ 60]: 0.44 [0.22; 0.88], 0.020); (S IgG [AUC ≥ 237]: 0.31 [0.16; 0.61], <0.001). Viral RNA-load in plasma and N-antigenaemia predicted increased mortality: (N1-viral load [≥2.156 copies/ml]: 2.25 [1.16; 4.36], 0.016); (N-antigenaemia: 2.45 [1.27; 4.69], 0.007). CONCLUSIONS: Low anti-SARS-CoV-2 S antibody levels predict mortality in critical COVID-19. Our findings support that these antibodies contribute to prevent systemic dissemination of SARS-CoV-2.

ABSTRACT

Resumen Introducción y objetivos: La pandemia de COVID-19 causada por infección del virus SARS-CoV-2 ha saturado al sistema sanitario español, afectándose la atención de las enfermedades cardiovasculares. Queremos cuantificar el impacto de la pandemia en el número de las intervenciones quirúrgicas cardíacas analizando los grupos relacionados con el diagnóstico (GRD) más prevalentes de nuestra especialidad. Métodos: A instancias de la Sociedad Española de Cirugía Cardiovascular y Endovascular se solicitó a todos lo centros nacionales que quisieron participar, los datos de los códigos de GRD números 162 (cirugía sobre válvulas cardíacas con infarto o diagnóstico complejo), 163 (cirugía sobre válvulas cardíacas sin infarto o diagnóstico complejo), 165 (bypass coronario con infarto o diagnóstico complejo), 166 (bypass coronario sin infarto o diagnóstico complejo) y 167 (otros procedimientos cardiotorácicos o vasculares torácicos) entre el 1 de marzo de 2020 y el 30 de septiembre de 2020 (7 meses), y como período control las mismas fechas de 2019. Resultados: Se recibieron los datos de 24 Hospitales, 22 públicos y 2 privados. Existió un descenso global en el número de intervenciones del 30% (Rango -19% a -42%, p<0.001) de 4648 en 2019 a 3262 en 2020 (-1386 de diferencia), siendo +7% para el GRD 162 (p=0.500), -37% para el 163 (p=0.001), -9% para el 165 (p=0,304), -32% para el 166 (p=0.001), y -16% para el 167 (p=0.062). Conclusiones: existió un descenso global de cirugías estadísticamente significativo en 2020 del 30% respecto a 2019 entre el 1 de marzo y el 30 de septiembre. Introduction and objectives: The COVID-19 pandemic caused by the SARS-CoV-2 virus infection has saturated the Spanish health system, affecting the care of cardiovascular diseases. In this phase 2 of the SECCE-COVID19 study we want to quantify the impact of the pandemic on the number of cardiac surgeries by analyzing the most prevalent diagnostic-related groups (DRGs) in our specialty. Methods: At the request of the Spanish Society of Cardiovascular and Endovascular Surgery, all the centers in the national territory that wanted to participate were asked for the data of the DRG codes number 162 (surgery on heart valves with infarction or complex diagnosis), 163 (surgery on heart valves without infarction or complex diagnosis), 165 (coronary bypass with infarction or complex diagnosis), 166 (coronary bypass without infarction or complex diagnosis) and 167 (other cardiothoracic or thoracic vascular procedures) between March 1, 2020 and September 30, 2020 (7 months), and as a control period the same dates of the year 2019. Results: Data were received from 24 Hospital Centers, 22 public and 2 private. There was a global decrease in the number of interventions of 30% (Range -19% a -42%, p<0.001) from 4648 in 2019 to 3262 in 2020 (-1386 difference), being +7% for the GRD 162 (p=0.500), -37% for 163 (p=0.001), -9% for 165 (p=0,304), -32% for 166 (p=0.001) and -16% for 167(p=0.062). Conclusions: there was a statistical significant global decrease in surgeries in 2020 of 30% compared to 2019 between March 1 and September 30.

ABSTRACT

Background: Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome-Corona Virus 2 has generated significant impact on global health worldwide. COVID-19 can cause pneumonia and organ injury. Chronic kidney disease (CKD) has been associated with increased mortality in previous epidemics, but there is a paucity of data regarding actual risks for non-dialysis CKD patients with COVID-19. Methods: Multicenter, observational cohort study including 136 non-dialysis CKD patients and 136 age- and sex-matched controls that required hospitalization due to COVID-19. Patients with end-stage renal disease, a kidney transplant or without registered baseline glomerular filtration rate prior to COVID-19 infection were excluded. CKD and acute kidney injury (AKI) were defined according to KDIGO criteria. Results: CKD patients had higher white blood cell count and D-dimer and lower lymphocyte percentage. No differences were found regarding symptoms on admission. CKD was associated with higher rate of AKI (61 vs. 24.3%) and mortality (40.4 vs. 24.3%). Patients with AKI had the highest hazard for death (AKI/non-CKD HR:7.04, 95% CI:2.87-17.29; AKI/CKD HR:5.25, 95% CI: 2.29-12.02), followed by CKD subjects without AKI (HR:3.39, 95% CI:1.36-8.46). CKD status did not condition ICU admission or length of in-hospital stay. Conclusions: CKD patients that require hospitalization due to COVID-19 are exposed to higher risk of death and AKI.

ABSTRACT

BACKGROUND: COVID-19 can course with respiratory and extrapulmonary disease. SARS-CoV-2 RNA is detected in respiratory samples but also in blood, stool and urine. Severe COVID-19 is characterized by a dysregulated host response to this virus. We studied whether viral RNAemia or viral RNA load in plasma is associated with severe COVID-19 and also to this dysregulated response. METHODS: A total of 250 patients with COVID-19 were recruited (50 outpatients, 100 hospitalized ward patients and 100 critically ill). Viral RNA detection and quantification in plasma was performed using droplet digital PCR, targeting the N1 and N2 regions of the SARS-CoV-2 nucleoprotein gene. The association between SARS-CoV-2 RNAemia and viral RNA load in plasma with severity was evaluated by multivariate logistic regression. Correlations between viral RNA load and biomarkers evidencing dysregulation of host response were evaluated by calculating the Spearman correlation coefficients. RESULTS: The frequency of viral RNAemia was higher in the critically ill patients (78%) compared to ward patients (27%) and outpatients (2%) (p < 0.001). Critical patients had higher viral RNA loads in plasma than non-critically ill patients, with non-survivors showing the highest values. When outpatients and ward patients were compared, viral RNAemia did not show significant associations in the multivariate analysis. In contrast, when ward patients were compared with ICU patients, both viral RNAemia and viral RNA load in plasma were associated with critical illness (OR [CI 95%], p): RNAemia (3.92 [1.183-12.968], 0.025), viral RNA load (N1) (1.962 [1.244-3.096], 0.004); viral RNA load (N2) (2.229 [1.382-3.595], 0.001). Viral RNA load in plasma correlated with higher levels of chemokines (CXCL10, CCL2), biomarkers indicative of a systemic inflammatory response (IL-6, CRP, ferritin), activation of NK cells (IL-15), endothelial dysfunction (VCAM-1, angiopoietin-2, ICAM-1), coagulation activation (D-Dimer and INR), tissue damage (LDH, GPT), neutrophil response (neutrophils counts, myeloperoxidase, GM-CSF) and immunodepression (PD-L1, IL-10, lymphopenia and monocytopenia). CONCLUSIONS: SARS-CoV-2 RNAemia and viral RNA load in plasma are associated with critical illness in COVID-19. Viral RNA load in plasma correlates with key signatures of dysregulated host responses, suggesting a major role of uncontrolled viral replication in the pathogenesis of this disease.
