Mild versus severe COVID-19: Laboratory markers

Area of Science:

• Medical Science
• Infectious Diseases
• Critical Care Medicine

Background:

• The global increase in COVID-19 cases presents significant challenges for intensive care unit (ICU) management.
• Accurate patient triaging is essential for effective resource allocation and timely treatment.

Purpose of the Study:

• To identify key laboratory parameters for predicting severe COVID-19.
• To aid clinicians in the early risk stratification of hospitalized COVID-19 patients.

Main Methods:

• Analysis of clinical status, including peripheral oxygen saturation (SpO2) and comorbidities.
• Evaluation of specific laboratory markers such as lymphocyte count, C-reactive protein (CRP), D-dimers, ferritin, cardiac troponin, and interleukin-6 (IL-6).

Main Results:

• Low lymphocyte counts and elevated serum levels of CRP, D-dimers, ferritin, troponin, and IL-6 are associated with increased disease severity.
• These laboratory parameters can be utilized in risk stratification models.

Conclusions:

• Specific laboratory markers are valuable tools for predicting severe COVID-19 outcomes.
• Early identification of patients at high risk for unfavorable disease progression can improve patient management and outcomes.
