Abstract

In prediabetes, blood glucose levels are higher than normal; however, they remain below the diabetes threshold. Studies conducted on biomarkers for this disease result in controlling diabetes mellitus (DM) or reducing the risk of developing complications. Lipid profile parameters are considered important predictors of DM. Therefore, this study was conducted on three groups of normoglycemic (n=30), pre-diabetics (n=125), and diabetics (n=30) to recognize the predictive role of lipid parameters in the transition from pre-diabetes to diabetes. In this experiment, in addition to total cholesterol and triglycerides, very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride/HDL ratio, and fasting triglyceride-fasting blood glucose (FBG) index were measured. Based on the results, medians for total cholesterol, LDL, HDL, LDL/HDL ratio, cholesterol/HDL ratio, and LDL/HDL ratio did not differ significantly across the groups of normoglycemia, prediabetes, and diabetes. For triglyceride, the medians were significantly higher in pre-diabetes and also diabetes, compared to normoglycemia (i.e., 127.9 and 129.1 vs. 94.5 mg/dL, respectively [P<0.001]). Moreover, the same results were observed in the case of VLDL (i.e., 25.6 and 30.9 vs. 18.9 mg/dL, respectively). The triglyceride/HDL ratio significantly increased pre-diabetics and diabetics, compared to normoglycemic (2.72 and 2.67 vs. 2.18, respectively). Moreover, the median of the triglyceride-FBG index significantly had an increase in pre-diabetics and diabetics, compared to normoglycemic (8.89 and 9.38 vs. 8.22, respectively). The importance of triglyceride, VLDL, triglyceride/HDL ratio, and triglyceride-FBG index in distinguishing between pre-diabetes and normoglycemia was verified by a receiver operating characteristic curve analysis of the results. Logistic regression analysis confirmed the risk effects of the four parameters on pre-diabetes and diabetes. Therefore, triglyceride, VLDL, triglyceride-FBG index, and triglyceride/HDL ratio are considered promising biomarkers used to predict pre-diabetes and DM in the general population.

Keywords

1. Introduction

Type 2 diabetes mellitus (T2DM) is recognized as a public health concern with a major impact on the overall quality of life and human health. The overall economic development and urbanization in lifestyle increase the burden of disease in various parts of the world, such as Iraq ( 1 , 2 ). The problem is further complicated by comorbidities of the cardiovascular system as T2DM patients are more susceptible to coronary artery disease, linked to increased mortality rates among these patients ( 3 , 4 ). In this context, two major modifiable risk factors of T2DM are investigated which include dyslipidemia and hypertension with both factors accounting for two-thirds of the disability among T2DM patients worldwide ( 5 ). Diabetic dyslipidemia, defined by the American Diabetes Association, is used to describe dysregulated levels of lipids in patients with type 2 diabetes (T2DM), including total cholesterol, triglyceride, very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) ( 6 ). Abnormal levels of these lipid parameters increase the particular concern due to their complex clinical implications in T2DM patients ( 7 ). In the case of pre-diabetes, a transition metabolic state from normoglycemia to T2DM leads to an increased risk of cardiovascular disease ( 8 ), and the patients have abnormalities in the lipid profile. However, the correlation among pre-diabetes, T2DM, and lipids may be subjected to ethnic differences, depending on the patient's nutritional status, environment, and lifestyle ( 9 ). Furthermore, some studies revealed the predictive significance of lipid parameters in the outcome of pre-diabetes ( 10 , 11 ). A fasting triglyceride-fasting blood glucose (FBG) index was investigated to help predict insulin resistance and cardiovascular illness in people with type 2 diabetes ( 4 ). Therefore, this study was conducted on three groups of Iraqi individuals, including normoglycemic, pre-diabetics, and diabetics (T2DM) to understand the predictive role of lipid parameters in the transition from pre-diabetes to diabetes.

2. Materials and Methods

2.1. Populations Studied

This prospective study was conducted on three different groups of people including 30 apparently healthy individuals, normoglycemia, (42.5±12.9 years; 50% males), 125 pre-diabetics (47.2±11.1 years; 53.6% males), and 30 T2DM patients (49.8±13.1 years; 50% males) from December 2020 to May 2021. The normoglycemia, pre-diabetes, and diabetes were defined according to the American Diabetes Association criteria, based on assessing FBG less than 100, between 100 and 125, and ≥ 126 mg/dL, respectively, as well as glycated hemoglobin (HbA1c: less than 5.7, between 5.7 and 6.4, and ≥ 6.5%, respectively) ( 12 ). Only people who met these criteria were included in this study; in addition to pregnant women with gestational diabetes, smokers, alcoholics, and patients with cardiovascular and kidney diseases and hepatic failure were excluded from the study.

2.2. Laboratory Methods

Blood samples were collected by a vein puncture after 10-12 h of fasting, and the blood sample (5 mL) was split into two aliquots for further testing and analysis. The first aliquot (2 mL) was dispensed into a tube containing ethylene-diamine tetra-acetic acid (EDTA), removed from the tube (EDTA), and then processed in less than three hours and utilized for HbAlc measurement in the same manner as stated earlier. The second aliquot (remaining blood [3 mL]) was transferred to a plain tube, and after clotting, the tube was centrifuged (3000 rpm for 15 min) to gather serum and assess for FBG, total cholesterol, triglyceride, VLDL, LDL, and HDL using Cobas c 311 analyzer (Cobas-Roche, Germany) preloaded with the respective reagent kits. In addition, two related indices were assessed, including triglyceride-FBG index and triglyceride/HDL ratio. The former index is computed using the following equation: ln [fasting triglycerides (mg/dl) FBG (mg/dl)/2] ( 13 ).

2.3. Statistical Analysis

All non-parametric variables (including skewed variables) were represented as the median and interquartile range (IQR: 25%-75%) and a significant difference between medians was determined using the Kruskal-Wallis test, followed by the Mann-Whitney U test, respectively. The prognostic relevance of total cholesterol, triglyceride, VLDL, LDL, and HDL in prediabetes and diabetes was determined using receiver operating characteristic (ROC) curve analysis. The area under the curve (AUC), 95% confidence interval (CI), cut-off value, sensitivity, and specificity were all used to assess the significance. To estimate the odds ratio (OR) and 95% CI, the participants were distributed into two groups according to the median of total cholesterol, triglyceride, VLDL, LDL, and HDL (&gt; and ≤ median), and then logistic regression analysis was conducted. A P-value of ≤0.05 was considered statistically significant. The statistical analysis was conducted using the IBM SPSS software (version 25; Armonk, NY: IBM Corp).

3. Results

3.1. Fasting Blood Glucose and Glycated Hemoglobin

Medians of FBG and Hb1Ac were significantly elevated in pre-diabetes (106.6 [IQR:103.7%-112.5%] mg/dL and 5.90 [IQR: 5.80%-6.20%], respectively; P<0.001) and diabetes (157.14 [IQR: 133.0%-181.2%] mg/dL and 7.05 [IQR: 6.70%-8.11%], respectively; P<0.001), compared to normoglycemia (80.2 [IQR: 77.1%-86.1%] mg/dL and 4.50 [4.10%-4.70%], respectively). Both medians were also significantly increased in diabetes, compared to prediabetes (P<0.001) (Figure 1).

3.2. Serum Profile of Lipids

As indicated in table 1, no significant change was in total cholesterol, LDL, HDL, LDL/HDL, and cholesterol/HDL ratio among the groups of normoglycemia, pre-diabetes, and diabetes. For triglyceride, the medians were significantly higher in pre-diabetes and diabetes than normoglycemia (i.e., 127.9 [IQR: 104.4%-190.9%] and 129.1 [IQR: 95.5%-192.7%] vs. 94.5 [IQR: 76.5%-100.5%] mg/dL, respectively; P<0.001). A similar observation was also made in the case of VLDL (25.6 [IQR: 20.9%-36.8%] and 30.9 [IQR: 22.7%-42.1%] vs. 18.9 [IQR: 15.2%-20.1%] mg/dL, respectively; P<0.001). Moreover, the triglyceride/HDL ratio was significantly increased in pre-diabetics (2.72 [IQR: 2.16%-4.03%]) and diabetics (2.67 [IQR: 1.73%-4.14%]), compared to normoglycemic (2.18 [IQR: 1.63%-2.55%]; P=0.003), while no considerable difference was between pre-diabetics and diabetics. In addition, a significantly increased median of the triglyceride-FBG index was in pre-diabetics (8.89 [IQR: 8.65%-9.20%]) and diabetics (9.38 [IQR: 9.05%-9.57%]), compared to normoglycemic (8.22 [8.03%-8.31%]; P<0.001), and this increase was more obvious in diabetics with a significant difference, compared to pre-diabetics (Table 1).

3.3. ROC Curve Analysis

ROC curve analysis demonstrated the significance of triglyceride, VLDL, triglyceride/HDL ratio and triglyceride-FBG index among normoglycemia and prediabetes or diabetes. In the case of triglyceride, the calculated AUCs were 0.822 (95% CI: 0.756-0.888; P<0.001; cut-off value=100.1 mg/dL; sensitivity=76.7%; specificity=76.7%) and 0.783 (95% CI: 0.656-0.911; P<0.001; cut-off value=100.1 mg/dL; sensitivity=73.3%; specificity=73.3%) in pre-diabetes and diabetes, respectively. Higher AUCs with better sensitivity and specificity were associated with VLDL. In pre-diabetes vs. normoglycemia, the AUC was 0.823 (95% CI: 0.756-0.889; P<0.001; cut-off value=20.3 mg/dL; sensitivity=78.4%; specificity=76.7%) and in diabetes vs. normoglycemia was 0.824 (95% CI: 0.704-0.945; P<0.001; cut-off value=20.7 mg/dL; sensitivity=80.0%; specificity=80.0%). However, significantly better AUC values were recorded for the triglyceride-FBG index, which were 0.924 and 0.978 in pre-diabetes and diabetes, respectively, with the sensitivity and specificity improved and exceeded 86% (Tables 2 and 3; Figures 2 and 3).

3.4. Logistic Regression Analysis

Triglyceride and VLDL were linked to an increased chance of developing pre-diabetes or diabetes, according to a logistic regression study (Tables 4 and 5). The interest of the current study was the association of pre-diabetes, increased levels of triglycerides, and VLDL with ORs of 19.02 (95% CI: 4.44-81.41; P<0.001) and 17.82 (95% CI: 4.16-76.24; P<0.001), respectively. However, considering the triglyceride-FBG index leading to an increased risk of pre-diabetes and diabetes development, the estimated ORs were 32.44 (95% CI:4.43-237.54; P<0.001) and 188.50 (95% CI: 20.55-1729.43; P< 0.001), respectively.

3.5. Correlation Analysis

The correlation between triglyceride-FBG index and triglyceride/HDL ratio was analyzed in normoglycemic, pre-diabetics, and diabetics using Spearman's rank correlation test, showing a significant positive correlation between the two parameters in the three groups, while the correlation coefficient (rs) showed different values. The highest rs was recorded in pre-diabetics (rs=0.882; P<0.001), followed by normoglycemic (rs=0.768; P<0.001) and diabetics (rs=0.162; P<0.001) (Figure 4).

4. Discussion

Based on the results, triglyceride and VLDL are two key lipid markers, which can identify pre-diabetes using ROC curve analysis, and are also linked to an increased risk of diabetes using logistic regression analysis. Pre-diabetics and diabetics had considerably higher levels of both measures in their blood. Furthermore, triglyceride in the triglyceride-FBG index leads to a predictive significance in distinguishing pre-diabetes and normoglycemia that recorded an AUC of 0.924, associated with a 32.44-folds raised risk of progressing pre-diabetes with the higher risk among diabetic patients (OR=188.50). Therefore, triglyceride, alone or incorporated in the triglyceride-FBG index, is considered a significant predictor of prediabetes and diabetes. In line with these findings, previous studies also revealed that triglyceride had elevated levels in prediabetics and T2DM patients, and their positive association with the risk of developing cardiovascular diseases was markedly recognized ( 14 - 16 ). Additionally, a link between high serum levels of triglyceride and over-secretion of insulin in apparently healthy individuals has been reported ( 17 , 18 ). Hypertriglyceridemia may have a causal relationship with insulin resistance, and reducing levels of triglyceride serum in the individuals with hypertriglyceridemia was associated with a decline in the levels of serum insulin and low incidence of T2DM ( 19 , 20 ). Therefore, changes in the levels of triglyceride were paralleled by changes in T2DM incidence, and a 4% elevated risk may accompany every 10 mg/dL increase in the triglyceride ( 21 ). Furthermore, hypertriglyceridemia was linked to increased mortality rates in T2DM patients due to cardiovascular diseases ( 22 ).

The current study also indicated that assessing the triglyceride-FBG index may be more important in predicting pre-diabetes and diabetes than triglyceride alone since this index is closely related to diabetes to recognize early insulin resistance without measuring insulin ( 23 ). Insulin resistance is considered a condition with an impaired biological response to insulin stimulation, resulting in reducing the disposal of glucose and hyperinsulinemia ( 24 ). Hyperglycemia, visceral adiposity hypertension, dyslipidemia, and up-regulated levels of inflammatory markers are all metabolic repercussions of insulin resistance, linked to an elevated risk of T2DM and cardiovascular disease ( 25 , 26 ). Impaired fasting glucose and/or glucose tolerance are observed in pre-diabetics, and lifestyle changes can lower the progression of prediabetes to diabetes by around 58% in three years ( 27 ). Moreover, insulin resistance can also drive some pathological events related to lipid deposition within insulin-responsive tissues (i.e. liver, viscera, and skeletal muscles) of prediabetics, leading to the low-grade type of inflammation and T2DM ( 28 ), and insulin resistance is also linked to high levels of VLDL ( 5 , 29 ). According to the results, VLDL levels were significantly elevated in pre-diabetics and diabetics, particularly in diabetics. A further study also confirmed that the VLDL was more up-regulated in the serum of diabetics than pre-diabetics; however, the levels were significantly higher in both groups than controls ( 30 ). Therefore, the lipid profile as a significant risk factor is highlighted in all T2DM follow-up programs virtually.

However, the triglyceride-FBG index and the triglyceride/HDL ratio were elevated in the serum of pre-diabetics and diabetics, compared to normoglycemia, the difference was only significant in pre-diabetics. This ratio is also known as the atherogenic index that is one of the most important risk factors for cardiovascular disease ( 31 ). A higher ratio of triglyceride/HDL is associated with endothelial dysfunction, proposed as a good marker of predicting insulin resistance ( 32 , 33 ). Regarding the results, this ratio can also be useful in monitoring glycemic control and identifying the risk of cardiovascular diseases in asymptomatic T2DM subjects ( 34 ). In Chinese cohort research, the triglyceride/HDL ratio substantially correlates with incident T2DM ( 35 ).

Therefore, triglyceride, VLDL, triglyceride-FBG index, and triglyceride/HDL ratio are considered promising biomarkers used to predict pre-diabetes and T2DM generally.
