Objective:
The association between the development of diabetic kidney disease (DKD) and the Triglyceride-glucose (TyG) index, a surrogate marker of IR was barely investigated. We studied the role of TyG index in determining the risk of microalbuminuria before grade 3 chronic kidney disease in type 2 diabetes.
Subjects And Methods:
This is a cross-sectional study including 365 patients with type 2 diabetes evaluated in the outpatient clinics of a tertiary center. Patients with febrile illness, obstructive uropathy, severe heart failure, stroke, non-diabetic renal disease, liver disease, malignant disease, autoimmune disease, patients with e-GFR < 60 mL/min/1.73 m2, and pregnant patients were excluded.
Results:
There was more severe insulin resistance in patients with microalbuminuria, as indicated by the TyG index (P = 0.004). Patients with microalbuminuria had a higher mean TyG index than normoalbuminuric patients (p = 0.035). The TyG index positively correlated with the urine albumin/creatinine ratio (r = 0.223, P < 0.001) and was independently associated with DKD in regression analyses. The optimal cut-off point of the TyG index was defined as > 9.66.
Conclusion:
The present study showed that higher TyG index levels were associated with increased risk of micro-and macroalbuminuria in type 2 diabetic patients.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
