A Correlation between Inflammatory Factors and Epileptic Seizures: A Meta-analysis

Area of Science:

• Neuroscience
• Immunology
• Biomarkers

Background:

• Pathophysiological mechanisms of epileptic seizures remain largely unknown.
• Elevated inflammatory factors in serum suggest a link to epileptic seizures.
• This study investigates the relationship between inflammatory factors and epileptic seizures.

Purpose of the Study:

• To explore the association between specific inflammatory factors and epileptic seizures.
• To identify potential biomarkers for epileptogenesis.

Main Methods:

• Comprehensive literature search across multiple databases (Embase, PubMed, Web of Science, etc.) up to December 2023.
• Meta-analysis of data on interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) in individuals with and without epileptic seizures.
• Evaluation of selected studies based on inclusion/exclusion criteria and data extraction for statistical analysis.

Main Results:

• Significantly elevated levels of IL-1β (SMD = 1.87), IL-6 (SMD = 1.73), and TNF-α (SMD = 2.16) were observed in individuals with epileptic seizures.
• Subgroup analysis revealed significant differences based on country, sampling time, and sample source.
• High heterogeneity (I2 > 96%) was noted across the analyzed inflammatory markers.

Conclusions:

• Increased levels of IL-1β, IL-6, and TNF-α are associated with epileptic seizures.
• These inflammatory markers show potential as biomarkers for epileptogenesis.
• Further research may elucidate their precise role in seizure pathophysiology.
