Laboratory Biomarkers Associated with Severity and Mortality of COVID-19
Insights
Elevated lactate dehydrogenase, blood urea nitrogen, and creatinine indicate higher risk for severe COVID-19 outcomes. These biomarkers can help predict intensive care unit (ICU) admission and mortality in patients with the virus.
Area of Science:
- Medical research
- Biomarker discovery
- Infectious disease epidemiology
Background:
- The COVID-19 pandemic necessitates identifying biomarkers for predicting disease severity.
- Early identification of high-risk patients is crucial for timely intervention and mortality reduction.
Purpose of the Study:
- To investigate laboratory results in COVID-19 patients in Saudi Arabia.
- To identify potential biomarkers correlated with COVID-19 disease severity.
Main Methods:
- Retrospective analysis of clinical records for 200 COVID-19 patients.
- Statistical investigation of laboratory tests including coagulation parameters, D-dimer, kidney, cardiac, and liver enzymes.
Main Results:
- Patients admitted to the ICU were older (mean 60 years) than ward patients (mean 47 years).
- Elevated magnesium, blood urea nitrogen, creatinine, and lactate dehydrogenase were observed in ICU and deceased patients.
- Blood urea nitrogen and creatinine levels were significantly higher in deceased patients (p < 0.05).
Conclusions:
- Elevated lactate dehydrogenase, blood urea nitrogen, and creatinine levels are potential biomarkers for COVID-19 severity.
- These markers may predict the risk of ICU admission and mortality.
- Identifying these biomarkers can aid physicians in selecting optimal therapeutic strategies.
Background:
Corona Virus Disease 2019 (COVID-19) emerged late 2019 and has become a global pandemic. There is an urgent need for identification of biomarkers to predict severity of the disease for early treatment and to avoid mortality especially in high-risk population. Therefore, the aim of this study is to investigate laboratory results in COVID-19 patients in Saudi Arabia to identify potential biomarkers correlated with disease severity.
Methods:
Clinical records of 200 patients diagnosed with COVID-19 from July to August 2020 at Jeddah East Hospital were retrospectively analyzed. Laboratory tests including coagulation parameters, D-dimer, kidney, cardiac, and liver enzymes were statistically investigated in patients admitted to wards and intensive care units (ICU).
Results:
The majority of patients admitted to ward (156/200) were young (mean 47 years old) compared to those admitted to ICU (mean 60 years old), 14/44 passed away in the ICU. Magnesium was significantly (p < 0.05) elevated in the ICU group while blood urea nitrogen and creatinine level was significantly higher in deceased patients (p < 0.05). Lactate dehydrogenase results were high among all groups, compared to normal range, although its level significantly increased (p > 0.05) in ICU and death groups.
Conclusions:
Elevated lactate dehydrogenase, blood urea nitrogen and creatinine levels may increase the risk of ICU admission and death from COVID-19, which can be used as potential biomarkers for disease severity. Using these markers could help physicians choose the optimal therapeutical option and provide patients with better treatment.
