N-glycosylation profiling of Type 2diabetes mellitus from baseline to follow-up: an observational study in a Ghanaian population.

Abstract

Aim: The study sought to determine the patterns of N-glycan profiles among Type 2 diabetes mellitus (T2DM) patients over a 6-month period. Materials & methods: Biochemical and clinical data were obtained from 253 T2DM patients at baseline and follow-up. Ultra-performance liquid chromatography and statistical methods were applied for N-glycan profiling. Results: The coefficients of variationwere 28%and 29% at baseline and follow-up, respectively, whereas the range of N-glycan variability was from 11%to 56%. Apart from GP1 (FA2) and GP29 (FA3G3S [3,3,3]3), the intra-individual variations of N-glycan peaks were not statistically significant. Conclusion: N-glycan profiles werestable over 6-month period in T2DM patients and could be used to monitor biochemical changes in relation with T2DM comorbidities.
