Abstract
Background
Epilepsy pathogenesis and progression are strongly influenced by inflammation. High-mobility group box-1 (HMGB1) is a key proinflammatory factor. The purpose of this study was to quantify and assess the relationship between HMGB1 level and epilepsy.
Methods
We searched Embase, Web of Science, PubMed, and the Cochrane Library for studies examining the relationship between HMGB1 and epilepsy. Two independent researchers extracted data and assessed quality using the Cochrane Collaboration tool. Data extracted were analyzed using Stata 15 and Review Manager 5.3. The study protocol was registered prospectively at INPLASY, ID: INPLASY2021120029.
Results
A total of 12 studies were eligible for inclusion. After exclusion of one study with reduced robustness, 11 studies were included, with a total of 443 patients and 333 matched controls. Two of the articles included cerebrospinal fluid and serum HMGB1 data, which were distinguished by “a” and “b,” respectively. The meta-analysis indicated that in comparison with the control group, the HMGB1 level was higher in epilepsy patients (SMD = 0.56, 95% CI = 0.27–0.85, P = 0.0002). Subgroup analysis of specimen types indicated that both serum HMGB1 and cerebrospinal fluid HMGB1 were higher in epilepsy patients than in the control group, with the increase in cerebrospinal fluid HMGB1 being more obvious. Subgroup analysis of disease types demonstrated that the serum HMGB1 level of epileptic seizure patients (including febrile and nonfebrile seizures) was significantly higher than that of matched controls. However, serum HMGB1 levels did not differ significantly between mild epilepsy patients and severe epilepsy patients. Patient age subgroup analysis showed higher HMGB1 in adolescents with epilepsy. Begg’s test did not indicate publication bias.
Conclusions
This is the first meta-analysis to summarize the association between HMGB1 level and epilepsy. The results of this meta-analysis indicate that epilepsy patients have elevated HMGB1. Large-scale studies with a high level of evidence are needed to reveal the exact relationship between HMGB1 level and epilepsy.
