Type 2 Diabetes Mellitus (T2DM) is a global health problem due to an increasing prevalence and incidence. HbA1c as aparameter for glycemic control is still above the desired target of 7%. Atherogenic Index of Plasma (AIP) is predicted to be anindicator of cardiovascular disease risk in T2DM. Dyslipidemia in T2DM patients showed a result of increased triglycerideand decreased HDL cholesterol levels. This study aimed to determine the relationship between HbA1c and AIP, triglycerides,and HDL cholesterol in T2DM patients. An analytical observational study using a cross-sectional method on 74 DMT2patients who underwent HbA1c and lipid profile examinations in January-March 2020. Atherogenic index of plasma wascalculated by the logarithmic equation (triglycerides/HDL cholesterol). Data were analyzed by SPSS 25.0. The relationshipbetween HbA1c with AIP, triglycerides, and HDL cholesterol using the Pearson correlation test. Atherogenic index of plasma(0.25±0.25) and triglycerides (211.92±146.09 mg/dL) were found to be higher in the poor glycemic control group (HbA1c> 7%) than AIP (-0.04±0.20) and triglycerides (108.96±38.96 mg/dL) in the good glycemic control group (p < 0.05). HDLcholesterol (40.08±12.64 mg/dL) was found to be higher in the poor glycemic control group than HDL cholesterol(52.28±18.12 mg/dL) in the good glycemic control group (p < 0.05). There was a significant positive correlation betweenHbA1c and AIP (r=0.411, p=0.000), HbA1c with triglycerides (r=0.418, p=0.000), and a significant negative correlationbetween HbA1c and HDL cholesterol (r=-0.233, p=0.046). Insulin resistance can cause lipid metabolism disorders,inflammation, oxidative stress, and coagulation disorders. Maintaining glycemic control and lipid control plays an importantrole in preventing diabetes complications. There is a significant positive correlation between HbA1c and AIP, HbA1c andtriglycerides, and a significant negative correlation between HbA1c and total cholesterol in T2DM patients.

Abstract Background In patients with type 2 diabetes mellitus (T2DM) the inflammatory and metabolic responses to epigallocatechin-3-gallate (EGCG) are unknown. Objectives Evaluate the impacts of EGCG on metabolic factors and some biomarkers of stress oxidative in patients with T2DM. Methods In this randomized, double-blind, placebo-controlled trial, 50 patients with T2DM consumed either 2 tablets (300 mg) EGCG (n=25) or wheat flour as placebo (n=25) for 2 months. The total antioxidant capacity (TAC), interleukin-6 (IL-6), lipid profile, mean arterial pressure (MAP), atherogenic index of plasma (AIP) were evaluated before and after the intervention. Results The finding of present study exhibited a significant increase in the serum levels of TAC after the EGCG supplementation (p=0.001). Also, in compare with control group, the mean changes of TAC were significantly higher in supplement group (p=0.01). In intervention group, a significant decrease was observed in the mean levels of triglyceride, total cholesterol, diastolic blood pressure (DBP), AIP, and MAP (p<0.05). Taking EGCG resulted in the mean changes of total cholesterol, MAP and DBP were significantly lower in compare with control group (p<0.05). Conclusions This study recommended that EGCG supplementation may be improved blood pressure, lipid profile, AIP, and oxidative status in patients with T2DM.

Introduction: Diabetes mellitus type 2 has become a global health-care problem of modern society due to a pronounced increase of prevalence to pandemic proportions and vascular complications. At present, glycated hemoglobin (HbA1c) is widely accepted as a measure of glycemic control in established diabetes. The aim of this study was to analyze the lipid profile in serum of patients with diabetes mellitus type 2, and its relationship with HbA1c levels. Methods: The observational cross-sectional study included 60 diabetic patients, 30 men, and 30 women, age 32–94 years. Patients were assigned into two groups based on HbA1c values; Group 1: HbA1c ≤ 7% (good glycemic control) and Group 2: HbA1c > 7% (poor glycemic control). We analyzed the concentration of glucose, HbA1c, and lipid profile including total cholesterol levels, triglycerides (TAG), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Results: Significantly lower values of glucose concentration, TAG and the ratio TAG/HDLc were obtained in the group of patients with good glycemic control. (p < 0.0005) Patients with good glycemic control had lower values of Castelli 1 and Castelli 2 index, and atherogenic index of plasma, compared to patients with poor glycemic control, but this difference was not significant. (p > 0.005) Our study revealed a significant positive correlation between HbA1c and triglyceride level (r = 0.375; p = 0.003) and HbA1c and ratio triglyceride/HDLc (r = 0.335; p = 0.009). Conclusion: HbA1c can also be used as a predictor of dyslipidemia in type 2 diabetics in addition to as a glycemic control parameter.

Diabetes mellitus patients often have hypercoagulable blood, as evidenced by the increased coagulation, impaired fibrinolysis,endothelial dysfunction and platelet hyperactivity. Hyperactive platelet is the major determinant of pro thrombotic state in DM. Byassessing the MPV and platelet aggregation, which is a marker of platelet activity, in patients with type 2 DM, it is expected to help theprediction of acute events. This research is aimed to know the differences of MPV and the aggregation of platelet between poor glycemiccontrol as well as good the control group in type 2 DM patients. This study was conducted in cross sectional method using 22 people withgood glycemic control and 28 people with poor one (glycemic control) from June to August 2013. Fasting blood samples were analyzedfor CBC, HbA1c, TG and platelet aggregation. MPV and platelet aggregation value were compared between groups using independentt-test. Based on this study, there is no significant difference in MPV and platelet aggregation between groups (p=0.598, p=0.464 (1 μM),p=0.868 (2 μM), p=0.984 (5 μM), p=0.401 (10 μM)). Mean Platelet Volume (MPV) correlate significantly with platelet aggregationat 1 μM and 5μM ADP concentration in good glycemic control group (r=0.591; p=0.004 at 1 μM ADP and r=0.521; p=0.013 at 5 μMADP). Mean platelet volume correlate significantly with the platelet aggregation at 2 μM ADP and the concentration in poor glycemiccontrol group (r=0.405; p=0.033). There are no significant differences in MPV and platelet aggregation between groups, but there is asignificant correlation between them (MPV and platelet aggregation) in the good glycemic control of the type 2 DM group.

Background & Objectives:  Adenosine modulates insulin action on various tissues and its concentration in tissues is affected by Adenosine Deaminase (ADA) levels. ADA is an enzyme involved in purine metabolism and is considered to be a marker of T cell activation. Immunological disturbances in type 2 diabetic individuals have an association with cell mediated responses and inappropriate T-lymphocyte function. Hence, the study was undertaken to determine the levels of Serum ADA activity in patients of type 2 DM and its correlation with parameters of glycemic profile such as Fasting blood sugar (FBS) and Glycated Haemoglobin. Material and Methods- A total of 100 patients diagnosed for type 2 DM visiting the Outpatient Department of General Medicine and Endocrinology at Mahatma Gandhi Medical College & Hospital, Jaipur were enrolled for the study based on predefined inclusion and exclusion criteria. Blood samples were collected for all enrolled patients and analysed for the investigations like Serum BSF, HbA1c and Serum ADA. Results- In the study, BSF, mean HbA1c and serum ADA level was significantly higher in diabetic group in comparison to control group (p=0.000). The diabetic group was subdivided on the basis of HbA1c levels, HbA1c ≤ 8% as good glycemic control and HbA1c > 8% as poor glycemic control. BSF, mean HbA1c and serum ADA levels were observed to be significantly higher in poor glycemic control group as compared to that of good glycemic control. A significant positive correlation between S. ADA and HbA1c activity was also seen (r= 0.388). Conclusion- Increased ADA level can be used to determine the glycemic status in the patients of type 2 DM and serve as a marker for insulin resistance. Hence, by analysing ADA levels in diabetes, glycemic control and insulin resistance can be assessed. Raised ADA levels can be an early indicator of progressive diabetic change and help to take preventive measures for the development of diabetic complication and thereby improving the outcome of the disease. Keywords- Diabetes Mellitus, Adenosine Deaminase, Glycated haemoglobin

Background: Type 2 diabetes mellitus (T2DM) is a chronic condition with an impairing effect on multiple organs. Numerous respiratory disorders have been observed in patients with T2DM. However, T2DM e ect on pulmonary function is ff inconclusive. Aims: In this study, we investigated the effect of T2DM on respiratory function and the correlation of glycemic control, diabetes duration and insulin intake. Methods: 1500 patients were recruited for this study, 560 having T2DM for at least a year were included in the final data, in addition to 540 healthy volunteers. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory flow at 25-75% (FEF 25-75%), as well as FEV1/FVC ratio values were measured. Results: A two-sample t-test showed that z-scores produced by Al-Qerem et al.’s equations for FEV1, FVC, and FEF 25-75% were significantly lower for the T2DM group than the control group (p < 0.01). FEV1/FVC ratio in T2DM group were significantly higher (p < 0.01). Multiple linear regression analysis found that glycemic control represented by HbA1c as well as disease duration were negatively associated with pulmonary function (p < 0.01). However, insulin intake was found to have no significant correlation with the pulmonary function. Conclusion: T2DM was linked to reduced pulmonary function and was consistent with a restrictive ventilation pattern. HbA1c as well as disease duration were independent risk factors for reduced pulmonary function.

Abstract Background The association of the atherogenic index of plasma (AIP), an emerging lipid index that can predict the risk for cardiovascular disease, with adverse outcomes in type 2 diabetes mellitus (T2DM) patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) has not been determined. Therefore, the aim of this study was to investigate whether the AIP could independently predict adverse cardiovascular events in T2DM patients with ACS undergoing PCI. Methods This study was a retrospective analysis of a single-centre prospective registry involving 826 consecutive T2DM patients who underwent primary or elective PCI for ACS from June 2016 to November 2017. This study ultimately included 798 patients (age, 61 ± 10 years; male, 72.7%). The AIP was calculated as the base 10 logarithm of the ratio of the plasma concentration of triglycerides to high-density lipoprotein-cholesterol (HDL-C). All the patients were divided into 4 groups based on the AIP quartiles. The primary endpoint was a composite of death from any cause, non-fatal spontaneous myocardial infarction (MI), non-fatal ischaemic stroke, and unplanned repeat revascularization. The key secondary endpoint was a composite of cardiovascular death, non-fatal MI, and non-fatal ischaemic stroke. Results During a median follow-up period of 927 days, 198 patients developed at least one event. An unadjusted Kaplan-Meier analysis showed that the incidence of the primary endpoint increased gradually with rising AIP quartiles (log-rank test, P = 0.001). A multivariate Cox proportional hazards analysis revealed that compared with the lowest AIP quartile, the top AIP quartile was associated with significantly increased risk for the primary and key secondary endpoints (hazard ratio [HR]: 2.249, 95% confidence interval [CI]: 1.438 to 3.517, P < 0.001; and HR: 2.571, 95% CI: 1.027 to 6.440, P = 0.044, respectively). Conclusions A higher AIP value on admission was independently and strongly associated with adverse cardiovascular events in T2DM patients with ACS undergoing PCI.
