High Expression of Mannose-Binding Lectin and the Risk of Vascular Complications of Diabetes: Evidence from a Meta-Analysis.

Abstract

BACKGROUND:

Vascular inflammation associated with mannose-binding lectin (MBL) may be implicated in the pathogenesis of vascular complications in diabetes. The purpose of this study is to evaluate the association of MBL expression with vascular complications in diabetes.

MATERIALS AND METHODS:

Data from published case-control studies on MBL expression and vascular complications of diabetes were collected up to September 30, 2014. Medline, Embase, and Chinese National Knowledge Infrastructure (CNKI) were searched using the key words "MBL or mannose-binding lectin or mannan-binding lectin," "diabetes or diabetic," and "vascular complication, vascular disease or angiopathy" to identify the articles published in English or Chinese.

RESULTS:

The combined odds ratio (OR) and 95% confidence interval (CI) for the cumulative rate of vascular complications in the cases of high-expression MBL versus that in cases of low-expression MBL were estimated using a fixed-effects model and a random-effects model. In total, 2,714 cases from 12 articles including 2,256 cases with high-expression MBL (≥ 400 μg/L) and 458 cases with low-expression MBL (< 400 μg/L) were reviewed. The cumulative vascular complication rates were 52.9% (1,194/2,256) in the cases with high expression and 38.4% (176/458) in those with low expression. The combined ORs were 1.6, with a 95% CI ranging from 1.24 to 2.08, in the fixed-effects model and 1.94, with a 95% CI from 1.00 to 3.76, in the random-effects model.

CONCLUSIONS:

High expression of MBL may be correlated with a significantly increased risk of vascular complications in diabetes. Thus MBL detection in diabetes is an effective and feasible method to predict vascular complications.
