ABSTRACT
Background:
The different waves of SARS-CoV-2 infection have strained hospital resources and, notably, intensive care units (ICUs). Identifying patients at risk of developing a critical condition is essential to correctly refer patients to the appropriate structure and to spare limited resources. The soluble form of RAGE (sRAGE), the endoplasmic stress response and its surrogates, GRP78 and VEGF-A, may be interesting markers.Methods:
This was a prospective monocenter cohort study of adult patients admitted to the ICU for severe COVID-19 pneumonia. The plasma levels of sRAGE, GRP78 and VEGF-A were measured within the first 24 h. Patients were classified as critical if they further needed vasopressor therapy, renal replacement therapy, or invasive mechanical ventilation, or died during their ICU stay, and were otherwise classified as not critical.Results:
A total of 98 patients were included and 39 developed a critical condition. Critical patients presented higher sRAGE (626 [450−1043] vs. 227 [137−404] pg/mL, p < 0.0001), interleukin-6 (43 [15−112] vs. 11 [5−20] pg/mL, p < 0.0001), troponin T (17 [9−39] vs. 10 [6−18] pg/mL, p = 0.003) and NT-pro-BNP (321 [118−446] vs. 169 [63−366] pg/mL, p = 0.009) plasma levels. No difference was observed for VEGF-A and GRP78. The variables independently associated with worsening in the ICU were sRAGE (1.03 [1.01−1.05] per 10 pg/mL) and age (1.7 [1.2−2.4] per 5 years). An sRAGE value of 449.5 pg/mL predicted worsening with a sensitivity of 77% and a specificity of 80%.Conclusion:
sRAGE may allow the identification of patients at risk of developing a critical form of COVID-19 pneumonia, and thus may be useful to correctly refer patients to the appropriate structure of care.
