System failure: Systemic inflammation following spinal cord injury

Area of Science:

• Neuroscience
• Immunology
• Metabolic Disorders

Background:

• Spinal cord injury (SCI) impacts hundreds of thousands in the US, with known effects on motor control and quality of life.
• Systemic consequences of SCI, particularly immunological and visceral dysfunctions, are less understood.
• The spinal cord regulates immune and visceral functions, which are disrupted by SCI, leading to organ inflammation and dysfunction.

Purpose of the Study:

• To review the immunological and metabolic consequences of SCI across multiple organs.
• To highlight the importance of understanding systemic effects for improving patient outcomes.

Main Methods:

• Review of existing literature on SCI's systemic effects.
• Analysis of immunological and metabolic changes in various organs post-SCI.

Main Results:

• SCI disrupts the regulation of systemic immunological and visceral functions.
• Organs such as the gut, spleen, liver, bone marrow, and kidneys exhibit local inflammation and physiological dysfunction after SCI.
• The severity of organ pathology correlates with injury level, severity, and time post-injury.

Conclusions:

• Infections and metabolic disorders are leading causes of reduced lifespan after SCI.
• Further research into the immunological and metabolic consequences of SCI is essential.
• Focusing on these deleterious aspects of SCI can improve lifespan and quality of life for affected individuals.
