Abstract

Aims

This study aimed to assess the relationship between hemoglobin glycation index (HGI) and risk of rapid kidney function decline (RKFD) in diabetic patients.

Methods

HGI was calculated as actual measured HbA1c minus predicted HbA1c. RKFD was defined as a 30 % decline in estimated glomerular filtration rate during follow-up. Participants were categorized into three groups based on HGI levels: lower (HGI ≤ −0.55), medium (−0.55 < HGI ≤ 0.22) and higher (HGI > 0.23). To understand the association between HGI and risk of RKFD in diabetic patients, directed acyclic graph were drawn and multivariate Cox proportional hazards models were used to adjust for covariates.

Results

During a median follow-up of 4.0 years, RKFD occurred in 43 patients (6.3 %) with diabetes. After adjusting for potential confounders, Compared to the lower-HGI group, the hazard ratios for RKFD were 1.75 (95 % confidence interval [95 % CI]: 0.72, 4.25) and 2.64 (95 % CI: 1.12, 6.21) in the medium- and higher-HGI groups, respectively. HGI showed a linearly associated with RKFD (P _{for nonlinear} = 0.383). The magnitude of associations was not materially altered in all sensitivity analyses, but with none significantly.

Conclusion

Higher HGI may be associated with an increased risk of RKFD in diabetic patients.

期刊介绍： Diabetes Research and Clinical Practice is an international journal for health-care providers and clinically oriented researchers that publishes high-quality original research articles and expert reviews in diabetes and related areas. The role of the journal is to provide a venue for dissemination of knowledge and discussion of topics related to diabetes clinical research and patient care. Topics of focus include translational science, genetics, immunology, nutrition, psychosocial research, epidemiology, prevention, socio-economic research, complications, new treatments, technologies and therapy.
