[Significance of hemoglobin A1C in the management of diabetes in dialysis patients]

What is the optimal dialysis method for diabetic patients with end stage kidney disease?

Diabetes is one of the most catastrophic diseases ruling every corner of the world, and this has led to elevated incidents of end-stage kidney disease (ESKD). The standard treatment for ESKD is kidney transplantation/replacement, which is limited due to a deficiency of donors. Hence, dialysis has become the second-best option for treating patients with ESKD. Patients with ESKD with underlying diabetes have an additional risk of complications and infections over non-diabetic ESKD patients. Furthermore, these patients also experience variations in blood glucose levels and are more liable to develop malnutrition. This article elaborates on the different dialysis methods for ESKD patients. This editorial highlights the evidence-based studies that include randomized clinical trials, cohort studies, retrospective studies and case-control studies and suggests the most suitable type of dialysis under the following components.

Relationships of social support, health-promoting lifestyles, glycemic control, and bone turnover among adults with type 2 diabetes

AIM

There is increasing evidence that hyperglycemia, oxidative stress, and the accumulation of advanced glycation end products in type 2 diabetes mellitus (T2DM) can lead to the deterioration of bone remodeling. The purpose of this study was to explore relationships of social support, health-promoting lifestyles, glycated hemoglobin (HbA1c) levels, and serum bone turnover markers (BTMs, including procollagen type I amino-terminal propeptide [PINP] and β-isomerised carboxy-terminal cross-linking telopeptide of type I collagen [β-CTX]) among individuals with T2DM.

METHODS

A total of 175 subjects were recruited by convenience sampling and divided into three groups based on their HbA1c levels. Statistical strategies of Spearman's correlation coefficient and multiple linear regression were used in this cross-sectional study.

RESULTS

There was a positive association between PINP and β-CTX, whereas the HbA1c level was inversely correlated with BTMs. Moreover, scores of both PINP and β-CTX were different in genders, males having lower levels of BTMs than females after adjustment for weight. Furthermore, both social support and health-promoting lifestyles were negatively correlated with HbA1c levels, whereas they did not significantly relate to declines in PINP and β-CTX.

CONCLUSION

High HbA1c levels detrimentally influence bone formation and bone resorption, and males with T2DM might be more susceptible to osteoporosis because of their relatively lower levels of BTMs. However, social support and health-promoting lifestyles could contribute to better glycemic control.
