ABSTRACT
Aim: The aim of this study is to analyze the effectiveness of the leukocyte albumin ratio (LAR) in predicting mortality in critical COVID-19 patients. Material(s) and Method(s): In this retrospectively-designed study, we evaluated a total of 98 critical patients who were hospitalized in the intensive care unit. Patients were divided into two groups according to hospital mortality as survivors (n=43) and non-survivors (n=55). Result(s): The non-survivors group was statistically significantly older (67.3+/-9.7 versus 62.5+/-10.9;p=0.023). HT and DM were detected more in the non-survivors group than in the survivors group (p=0.031, p=0.018, respectively). Mean LAR values were significantly higher in non-survivors than in survivors (5.9+/-3.5 versus 3.3+/-1.4;p<0.001). LAR values was positively correlated with urea (r=0.43, p<0.001), LDH (r=0.35, p<0.001), ferritin (r=0.25, p=0.015), procalcitonin (r=0.34, p<0.001), and pro-BNP (r=0.24, p=0.015) levels. A cut-off value of 3.71 ng/mL for LAR predicted mortality with a sensitivity of 76% and a specificity of 70% (AUC:0.779 95% Cl:0.689-0.870;p<0.001). Multivariable logistic regression analysis revealed that older age (OR:1.114, 95% CI:1.020-1.218;p=0.017) and increased ferritin (OR:1.003, 95% CI:1.001-1.004;p=0.002) and LAR (OR:1.583, 95% CI:1.073-2.337;p=0.021) values were independent predictors of mortality in patients with critical COVID-19. Discussion(s): LAR can be a useful and prognostic marker that can be used to predict mortality in COVID-19 patients admitted to the intensive care unit.Copyright © 2022, Derman Medical Publishing.

ABSTRACT
A novel coronavirus disease 2019 (COVID-19) outbreak has started in Wuhan, China, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The relationship between altered iron homeostasis and hyperinflammation may be hallmarks of COVID-19 disease. We aimed to compare some iron (ferritin and iron), inflammation (C-reactive protein [CRP], hemoglobin, lactate dehydrogenase [LDH], neutrophil) and coagulation (prothrombin time [PT], activated partial thromboplastin time [APTT], D-dimer, platelet) marker results of critical COVID-19 patients with healthy controls results. In this single center retrospective study, 50 critical patients diagnosed with COVID-19 were included, demographic, clinical characteristics, severity of disease and laboratory test results were elicited from electronic medical records and compared to 50 healthy people. A statistically significant increase in CRP, LDH, neutrophil, PT, APTT, D-dimer ferritin levels was observed in critical COVID-19 patients compared with healthy people while a statistically significant decrease was observed in hemoglobin and iron levels. In addition, no statistically significant change in platelet levels was observed. Ferroptosis may be a significant cause of multiple organ failure in critical COVID-19 patients. Ferroptosis inhibitors might have potential to combat ferroptosis in COVID-19. Therefore, larger studies are needed to ferroptosis in COVID-19 in vivo and in vitro.
