Potential Pathophysiological Mechanisms Underlying Multiple Organ Dysfunction in Cytokine Release Syndrome

Area of Science:

• Immunology
• Infectious Diseases
• Pathophysiology

Background:

• Emerging respiratory infections such as SARS-CoV, MERS, and COVID-19 pose significant global health threats.
• These infections are associated with high infectivity, rapid progression, mortality, and poor prognosis.
• Excessive immune activation leading to cytokine hypersecretion, known as cytokine release syndrome (CRS), exacerbates symptoms and can cause systemic multiple organ dysfunction.

Purpose of the Study:

• To elucidate the pathogenetic mechanisms of CRS in the context of severe respiratory infections.
• To describe key signaling pathways involved in CRS.
• To outline the clinical and pathophysiological characteristics of CRS.

Main Methods:

• This is a review article, synthesizing existing literature.
• Analysis of pathogenetic mechanisms of CRS.
• Description of signaling pathways and clinical features.

Main Results:

• CRS is a critical factor in the deterioration of severe respiratory infections.
• Specific signaling pathways driving CRS are identified.
• Clinical manifestations and pathophysiological consequences of CRS are detailed.

Conclusions:

• Understanding CRS mechanisms is crucial for managing severe respiratory infections.
• Further research into CRS pathways can identify specific drug targets.
• Developing targeted therapies for CRS holds promise for improving patient outcomes.
