Summary
New criteria can predict COVID-19 cytokine storm (CS) by analyzing inflammation, cell death, and electrolyte imbalance. This early detection may help manage hyperinflammation and reduce patient mortality.
Area of Science:
- * Infectious Diseases
- * Immunology
- * Critical Care Medicine
Background:
- * Cytokine storm (CS) is a severe hyperimmune response causing organ damage in some COVID-19 patients.
- * Early identification of COVID-19-associated CS is crucial for timely intervention.
- * Existing criteria for similar conditions do not effectively identify COVID-19 CS.
Purpose of the Study:
- * To develop and validate predictive criteria for COVID-19-associated cytokine storm (COVID-CS).
- * To identify laboratory markers indicative of hyperinflammation and tissue damage in COVID-19 patients.
- * To establish criteria for early diagnosis and therapeutic intervention.
Main Methods:
- * Analysis of laboratory results from 513 hospitalized COVID-19 patients within the first 7 days of admission.
- * Utilized logistic regression, principal component analysis, and a genetic algorithm to derive predictive criteria.
- * Validated the developed criteria in a separate cohort of 258 patients.
Main Results:
- * Established new predictive criteria for COVID-CS, achieving 0.85 sensitivity and 0.80 specificity.
- * Criteria integrate three clusters: inflammation, cell death/tissue damage, and prerenal electrolyte imbalance.
- * Identified patients with COVID-CS experienced longer hospital stays and higher mortality rates.
Conclusions:
- * Proposed novel, early predictive criteria for identifying cytokine storm in COVID-19 patients.
- * The criteria are practical for clinical use to guide early treatment strategies.
- * Early intervention based on these criteria may mitigate hyperimmune responses and decrease mortality.

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
