Abstract
CONTEXT Serum Mac-2 binding protein glycosylation isomer (M2BPGi) concentrations are known to be an indicator of chronic liver injury and fibrosis. OBJECTIVE This study aimed to investigate the association between serum M2BPGi concentrations and the development of type 2 diabetes in a Japanese community. METHODS A total of 2143 community-dwelling Japanese individuals aged 40-79 years without diabetes at baseline were followed up for 7 years. Serum M2BPGi concentrations were divided into quintiles: Q1, ≤0.37 cutoff index (COI); Q2, 0.38-0.49 COI; Q3, 0.50-0.62 COI; Q4, 0.62-0.80 COI; and Q5, ≥0.81 COI. Cox proportional hazards models were used to estimate hazard ratios and 95% CIs for the development of type 2 diabetes. RESULTS During the follow-up period, 219 individuals developed type 2 diabetes. The age- and sex-adjusted cumulative incidence of type 2 diabetes significantly increased with elevating serum M2BPGi levels (P for trend < .01). This association remained significant after adjustment for potential confounders (P for trend = .04). This significant association attenuated to a nonsignificant level after additionally adjusting for serum high-sensitivity C-reactive protein or homeostasis model assessment of insulin resistance. CONCLUSION The present study demonstrated that higher serum M2BPGi concentrations were significantly associated with higher risk of diabetes in a Japanese community. Moreover, inflammation and insulin resistance were suggested to contribute to the excess risk of diabetes in individuals with higher serum M2BPGi levels. These findings shed light on the importance of inflammation and insulin resistance when considering the pathogenesis of diabetes.

Application of Mac-2 binding protein glycosylation isomer as a non-invasive biomarker for probing liver disease. Sci Rep 2022; 12:6757. [PMID: 35474106 PMCID: PMC9043201 DOI: 10.1038/s41598-022-10744-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Accepted: 04/08/2022] [Indexed: 12/24/2022] Open
Abstract
Liver disease remains a major critical challenge in Thailand due to viral hepatitis. Clinical management requires close monitoring of liver fibrosis severity. Non-invasive testing is an attractive method for probing of disease progression. Mac-2 binding protein glycosylation isomer (M2BPGi) is a novel serum marker for fibrosis staging. The current study evaluates the marker among healthy donors and hepatitis C (HCV) patients. 100 HCV subjects were evaluated by liver biopsy. These patients had varying fibrosis severity based on METAVIR scores. Healthy donors were confirmed based on normal liver functions tests. Comparisons of M2BPGi levels among different study groups were performed and the effectiveness was evaluated using receiver operating characteristics (ROC) curves. Using liver biopsy as the reference standard, median M2BPGi levels in HCV cases were 0.74, 1.38 and 2.88 COI for F0-1, F2 and > F3 cases respectively. In healthy donors, the baseline values ranged 0.1–0.24 COI and statistically lower than liver disease cases profiled using M2BPGi. ROC analysis demonstrated superior results for M2BPGi levels among diseased populations and healthy controls. AUROC was determined at 0.983. Comparing with other non-invasive tests, M2BPGi showed a positive linear trend that indicated a strong match to existing methodologies. M2BPGi addresses a critical need in the management of liver disease by providing straightforward means to probe fibrosis severity. In this study, we found significant differences between hepatitis C and healthy subjects and established the background level in healthy donors.
