Relationship of insulin resistance to vitamin d status in children with no ndiabetic chronic kidney disease

Abstract EN

Insulin Resistance is common in patients with mild-to-moderate stage chronic kidney disease (CKD), even when the glomerular filtration rate is within the normal range.

This study aimed to investigate the association of IR and 25-hydroxyvitamin D levels.

In this study, we evaluated the frequency of IR in predialysis patients and the association with 25-hydroxyvitamin (OH)D levels.

A total of 32 non-diabetic patients with predialysis were included in the study.

Homeostasis model assessment for insulin resistance (HOMA-IR) index was calculated to show presence of IR.

Data were analyzed with the Statistical Package for the Social Sciences (SPSS) program version 13.0 (SPSS Inc, Chicago, Ill, USA) using the Chi-square, Student t-test, and logistic regression analysis.

Nineteen of 32 subjects (59.4 %) were detected to have IR.

There was no consistent relationship was detected between IR and glomerular filtration rate, body mass index, and blood pressure in chronic kidney disease (CKD).

However; significant difference was detected in 25(OH)D levels with IR in CKD (P = 0.49).

The regression analysis showed that 25(OH)D was an independent predictor of IR with an odds ratio of 1.2.

In our study, we demonstrated that IR was high in different stages of CKD.

Insulin-resistance in non-diabetic CKD was correlated with 25(OH)D levels.

25(OH) vitamin D levels can play a significant role in the development of IR in pediatric patients with CKD.

This is important for the early detection and intervention of vitamin D deficiency thereby preventing potentially future complications related to IR.
