Proinsulin/insulin ratio as a predictor of insulin resistance in patients with diabetic nephropathy.

Patients with Diabetic nephropathy (DN) have an increase in cardiovascular mortality, and since IR may be a contributing factor. Therefore, the aim of this study was to assess the role of pro insulin/insulin ratio as a predictor of insulin resistance in patients with diabetic nephropathy PATIENTS AND METHODS: A Case-control study was conducted in a total of 50 patients who diagnosed with type 2 diabetes mellitus from July 2017 to March 2018. The patients were divided into 2 groups according to presence of diabetic nephropathy. Demographic and clinical data were collected. RESULTS: There is a significant increase in serum pro insulin/insulin ratio in patients with diabetic nephropathy patients compared to patients without diabetic nephropathy An association was found between increase serum pro insulin/insulin ratio and increase predicting of insulin resistance. Cut-off value of serum pro insulin/insulin ratio ≥0.1145 with sensitivity and specificity of 92.3 and 60.3 respectively as a predictor for insulin resistance CONCLUSION: This study demonstrate a strong relationship between insulin resistance and CKD and this relationship was stronger in the presence of obesity. Pro insulin/insulin ratio was found to be a significant predictor for insulin resistance.
