“Comparison of Atherogenic Index of Plasma and Cholesterol/HDL Ratio Among Type 2 Diabetes Mellitus Patients in a Tertiary Care Hospital”

Abstract

Lipid prole though is a well established parameter to predict cardio vascular risk in patients suffering from type 2 diabetes mellitus(T2DM), at present lipid ratios are replacing these age old parameters. Among the lipid ratios Atherogenic index of plasma(AIP) and cholesterol/HDL(Chol/HDL) are found to be of great signicance. This cross-sectional study aimed to compare the predictive value of two lipid ratios, "Atherogenic index of plasma" (AIP) and "Cholesterol/HDL ratio" on basis of insulin resistance (IR) among 55 newly diagnosed cases with Type 2 Diabetes Mellitus (T2DM) and 50 control subjects. HOMA –IR (p value <0.0001), AIP (<0.001) and Cholesterol/HDL ratio (<0.001) were signicantly raised among case group in comparison to controls. Both AIP(r- 0.305, p-0.002) and Chol/HDL ratio(r- 0.23, p value- 0.018) was signicantly correlated with HOMA-IR. ROC curve of AIP and Chol/HDL ratio was plotted for identifying IR. There is no signicant difference between areas under curve (AUC) of AIP (AUC-0.656) and Chol/HDL ratio(AUC-0.630) (p value- 0.49). AIP was found to be correlated better with Insulin resistance than CHOL/HDL ratio. AUC in AIP was found to be slightly higher and overall sensitivity and specicity of AIP was found to be 66% and 69%, of Chol/HDL ratio was 46% and 76% to identify moderate to high-risk group: whereas it is 69%&47% of AIP and 87% and 32% of Chol/HDL ratio to identify low risk group. Both lipid ratios have some signicance in predicting cardio vascular risk in T2DM
