The Role of Serum High Mobility Group Box 1 and Interleukin-6 Levels in Acute Pancreatitis: A Meta-Analysis.

Abstract

The purpose of this meta-analysis was to comprehensively investigate the correlation between high mobility group box 1 (HMGB1) and interleukin-6 (IL-6) in relation to acute pancreatitis. A highly regulated exploration of various electronic databases, supplemented by manual searching methods, was performed in an attempt to identify pertinent articles of a useful nature. Subsequently, high-quality cohort studies that were deemed to comply with the arduous inclusion and exclusion criteria were selected for our meta-analysis. The extensive data analyses reported in our meta-analysis were conducted in connection with the Comprehensive Meta-analysis 2.0 (CMA 2.0). A total of 395 studies (135 Chinese studies and 260 English studies) were initially retrieved. 27 of those studies were selected for our meta-analysis, comprising of 896 cases of mild acute pancreatitis (MAP), 700 cases of severe acute pancreatitis (SAP) as well as 312 healthy controls. Pooled data suggested that serum HMGB1 and IL-6 levels of SAP and MAP patients were higher than in healthy controls. Moreover, serum HMGB1 and IL-6 levels of SAP patients exhibited significantly higher levels than in that of MAP patients. Based on the rigorous investigation of our meta-analysis, it was concluded that serum HMGB1 and IL-6 levels might be used as effective indicators for pancreatic lesions as well as the degree of inflammatory response, owing ultimately to the observations and data analyses, suggesting that serum HMGB1 and IL-6 levels share a close correlation with the severity of pancreatitis.
