RESUMO

A 44-year-old man with coronavirus disease 2019 (COVID-19) and nephrotic syndrome relapse was admitted to our intensive-care unit for respiratory failure. Despite receiving mechanical ventilation and immunomodulators, the patient experienced refractory hypoxemia, necessitating venovenous extracorporeal membrane oxygenation (VV-ECMO) therapy. Due to a worsening renal function, continuous hemodiafiltration was initiated. After 11 days, his respiratory status gradually improved, and VV-ECMO was withdrawn. The kidney function and proteinuria improved, and hemodialysis was subsequently discontinued. The patient was discharged 64 days after admission. This case highlights the potential benefit of early ECMO application in dramatically promoting recovery in severe COVID-19 cases.

RESUMO

Background: Arterial calcification is an important factor in determining the prognosis of patients with chronic kidney disease (CKD). Few studies on aortic calcification have involved radial artery calcification (RAC). This study aimed to analyze risk factors for RAC in patients with end-stage kidney disease (ESKD) and investigate the relationship between subsequent cardiovascular events (CVE) and vascular access trouble (VAT). Methods: This cohort study included 64 consecutive patients with ESKD who initiated hemodialysis and underwent a procedure for the creation of a primary radiocephalic arteriovenous fistula (RCAVF). Small arterial specimens were obtained from patients during RCAVF surgery. Tissue samples were stained with von Kossa, and arterial microcalcification was evaluated. We analyzed the association between preexisting arterial microcalcifications, clinical characteristics, CVE, and VAT. Results: In the univariate analysis, RAC patients demonstrated high systolic blood pressure (sBP), low hemoglobin (Hb), and low transferrin saturation (TSAT) (<0.05, <0.05, and <0.05, respectively). In the multivariate analysis, Hb (HR−0.516 (0.278−0.959), p < 0.05), TSAT (HR−0.0012 (0.00000248−0.597), p < 0.05), and sBP (HR−1.037 (1.001−1.073), p < 0.05) were independent risk factors for RAC. The cumulative incidence rate of CVE/VAT was not associated with RAC for one year. Conclusion: RAC was associated with sBP, TSAT, and anemia; however, no association with CVE/VAT was observed.
