| Summary: | Introduction: The increased incidence of diabetes and
Cardiovascular Disease (CVD) is attributed to the rising obesity
rates, which is one of the major factors contributing to Insulin
Resistance (IR). Although there is a close relationship between
obesity and IR, not all cases of obesity lead to cardiometabolic
complications. Visceral fat is considered to be the primary
cause of IR. Lipid Accumulation Product (LAP) is postulated as
a new continuous biomarker of visceral adiposity.
Aim: To determine the association between LAP and IR in
T2DM.
Materials and Methods: This institution-based cross-sectional
study was conducted over a period of three months at the
Department of Biochemistry, Rajarajeswari Medical College and
Hospital in Bengaluru, Karnataka, India. A total of 60 Type 2
diabetic patients (including newly diagnosed and known cases)
were recruited as cases, along with 30 healthy controls. Height,
weight, and Waist Circumference (WC) were measured. Fasting
blood samples were collected for laboratory biochemical
estimation of glucose, Total Cholesterol (TC), Triglycerides (TG),
High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL),
and fasting insulin. Statistical analysis for continuous variables
was performed using unpaired Student’s t-test, and Analysis of
Variance (ANOVA) test was used for group comparisons.
Results: Fasting serum insulin (p-value=0.007), Homeostatic
Model Assessment for Insulin Resistance (HOMA-IR)
(p-value=0.001), and LAP index (p-value<0.001) were significantly
higher in the case group. LAP index was divided into quartiles,
Insulin and HOMA-IR showed statistical significance across the
quartiles (p-value=0.005). The lipid profile analysis across LAP
quartiles revealed a progressive increase in TG levels (p<0.001)
and a decrease in HDL levels from Q1 to Q4 quartiles.
Conclusion: The study concludes that increased LAP levels are
associated with IR in T2DM. LAP can serve as a useful marker
for cardiometabolic risk in early-stage T2DM, enabling better
disease stratification for improved prognosis. |
