Could ischemia-modified albumin levels predict the severity of disease in SARS-CoV-2 infection?

Abstract

Introduction: Ischemia-modified albumin (IMA) level increases in inflammatory conditions. We aimed to investigate the association between IMA levels and the severity of coronavirus disease 2019 (COVID-19) infection in adult patients.

Methodology: We grouped adult patients with COVID-19 infection: Group A - mild symptoms, but normal computed tomography (CT), Group B - mild/moderate illness, and Group C - severe or critical illness. We measured IMA levels at the time of diagnosis of COVID-19 infection.

Results: Mean age of the total number of patients (n = 90) was 54.43 (± 8.11) year, and 46.7% (n = 42) were female. IMA levels were highest in Group C and lowest in A (p < 0.001). The most important factor predicting COVID-19 disease severity was IMA. Type 2 diabetes was more frequent in Group C (n = 31) than in Group B (n = 30) (p = 0.042). Asthma was less frequent, and coronary artery disease was more frequent in Group C than in Group A (n = 29) and B (p = 0.009). Duration of hospitalization was highest in Group C (p < 0.001).

Conclusions: We analyzed a sample of patients with COVID-19 infection and found that IMA predicted severe COVID-19 disease. Disease severity grouping was based on patients' clinical and radiological features. IMA level measured when SARS-CoV-2 infection is diagnosed may be a useful marker in predicting likely disease severity or intensive care need.
