Abstract Introduction: Gastrin release from G cells stimulates cholecystokinin (CCK2) receptors throughout the body, most of which promote gastric acid secretion. However, gastrin also stimulates CCK2 receptors located elsewhere, including the islet of the pancreas. In turn, gastrin increases insulin secretion1. Gastrin also promotes pancreatic β cell neogenesis and replication. Proton pump inhibitors (PPIs) decrease the pH of the stomach and stimulate gastrin secretion, which may indirectly promote insulin secretion and improve hemoglobin A1c (HbA1c). Objective: To understand the effect of PPIs on insulin-glucose homeostasis (c-peptide, HbA1c, and glucose) in patients with type 2 diabetes mellitus (T2DM). Methodology: We retrospectively reviewed the charts of patients with T2DM at least 18 years of age who received care at AnMed Health facilities from Jan. 1, 2018 through Dec. 31, 2018 to compare HbA1c, C-peptide, and glucose levels in patients with and without active PPI therapy. Slicer-dicer software was used to identify study population with diagnosis of T2DM and labs including both HbA1c and C-peptide. Out of total 215 patients satisfying inclusion criteria, 71 patients were on PPI. Statistical analyses were performed using SPSS version 20.0 (SPSS, Armonk, NY: IBM Corp). All values are presented as means ± SD. A p value of < 0.05 was considered to be significant. Independent T-test and chi-square test were performed to compare parameters in between groups. Results: The PPI and non-PPI groups had no statistical difference regarding age, sex, race and BMI. There was no significant difference in HbA1c levels between PPI and non-PPI groups (8.6% ± 2.1 vs 8.3% ± 2.0, respectively; p value = 0.37). However, we found a significant increase in C-peptide levels (3.1 ng/mL ± 2.4 vs 2.4 ng/mL ± 2.3; p value = 0.037) and decrease in LDL levels (79.6 mg/dL ± 34.0 vs 89.73 mg/dL ± 32.9; p value = 0.046) in the PPI group compared to non-PPI group. In addition, there was a significantly greater prevalence of coronary artery disease in the PPI group (p = 0.01). Conclusion: PPI therapy in patients with T2DM was not associated with improved glycemic control. However, C-peptide levels were significantly higher in patients with T2DM who were on PPI therapy suggesting higher insulin secretion. The lack of difference in HbA1c levels may be a result of aggressive diabetic management by treating clinicians to achieve similar goal HbA1c in both groups. Further research is needed to understand the gastrin pathway as a potential option for improving glycemic control. References: 1. Rehfeld JF.

Type 2 diabetes mellitus (T2DM) constitutes a major portion of Jordan’s disease burden, and incidence rates are rising at a rapid rate. Due to variability in the drug’s response between ethnic groups, it is imperative that the pharmacogenetics of metformin be investigated in the Jordanian population. The objective of this study was to investigate the relationship between twenty-one single nucleotide polymorphisms (SNPs) in the SLC22A1, SLC22A2, and SLC22A3 genes and their effects on metformin pharmacogenetics in Jordanian patients diagnosed with type 2 diabetes mellitus. Blood samples were collected from 212 Jordanian diabetics who fulfilled the inclusion criteria, which were then used in SNP genotyping and determination of HbA1c levels. The rs12194182 SNP in the SLC22A3 gene was found to have a significant association (p < 0.05) with lower mean HbA1c levels, and this association more pronounced in patients with the CC genotype (i.e., p-value was significant before correcting for multiple testing). Moreover, the multinomial logistic regression analysis showed that SNP genotypes within the SLC22A1, SLC22A2, and SLC22A3 genes, body mass index (BMI) and age of diagnosis were significantly associated with glycemic control (p < 0.05). The results of this study can be used to predict response to metformin and other classes of T2DM drugs, making treatment more individualized and resulting in better clinical outcomes.

Objective. Type 2 deiodinase (Dio2) is an enzyme responsible for the conversion of T4 to T3. The Thr92Ala polymorphism has been shown related to an increased risk for developing type 2 diabetes mellitus (T2DM). The aim of this study is to assess the association between this polymorphism and glycemic control in T2DM patients as marked by the HbA1C levels.Design and Methods.The terms “rs225014,” “thr92ala,” “T92A,” or “dio2 a/g” were used to search for eligible studies in the PubMed, Embase, and Cochrane databases and Google Scholar. A systematic review and meta-analysis of studies including both polymorphism testing and glycated hemoglobin (HbA1C) assays were performed.Results. Four studies were selected, totaling 2190 subjects. The pooled mean difference of the studies was 0.48% (95% CI, 0.18–0.77%), indicating that type 2 diabetics homozygous for the Dio2 Thr92Ala polymorphism had higher HbA1C levels.Conclusions. Homozygosity for the Dio2 Thr92Ala polymorphism is associated with higher HbA1C levels in T2DM patients. To confirm this conclusion, more studies of larger populations are needed.

Introduction: Diabetes mellitus (DM) is a non-communicable disease that has increased from year to year. Type 2 diabetes mellitus is not caused by lack of insulin secretion, but is caused by the failure of the body's cells to respond to the hormone insulin (insulin resistance). Insulin resistance was found to be a major contributor to atherogenic dyslipidemia. Dyslipidemia in DM risks 2 to 4 times higher than non-DM. Although dyslipidemia has a great risk for people with type 2 diabetes mellitus, this conventional risk factor only explains a portion (25%) of excess cardiovascular risk in type 2 DM. Discussion: In uncontrolled type 2 DM patients, LDL oxidation occurs faster which results from an increase in chronic blood glucose levels. Glycemic control as a determinant of DM progressivity is determined through HbA1c examination. HbA1c levels are associated with blood triglyceride levels. Meanwhile, triglyceride levels are associated with total cholesterol and HDL cholesterol levels. HbA1c levels are also associated with LDL cholesterol levels. Conclusion: There is a relationship between lipid profile and the progression of type 2 diabetes mellitus.   Keywords: type 2 diabetes mellitus, dyslipidemia, HbA1c, glycemic control, lipid profile

The present study included patients presenting with type 2 diabetes mellitus (DM2) of less than 10 years in duration having the HbA1c levels between 7.0% and 10.0%. They were treated with insulin detemir (once or twice daily) in combination with oral hypoglycemic agents (OHGA) and transferred thereafter to therapy with insulin glargine (Lantus, SoloSTAR) administered once daily. The patients were advised to adjust the dose of insulin glargine in order to achieve the desired fasting blood glucose level (FBGL) below 5.6 mmol/l. The HbA1c levels and FBGL, insulin doses, body weight, frequency of hypoglycemic episodes and adverse reactions were measured within 3 and 6 months after inclusion in the study; simultaneously, the patients and doctors' satisfaction with the treatment was estimated. A total of 915 patients were available for the examination (mean age 57.9±9.2 years, mean duration of DM2 5.9±2.3 years, average BMI 31.0±5.1 kg/m2). The number of the patients presenting with the HbA1c levels below 7% within 6 months after the onset of therapy amounted to 46.5% of the total. During the same period, percentage of the patients experiencing nocturnal and daytime glycemic episodes decreased. No cases of severe hypoglycemia were documented. Moreover, the body weight of the patients somewhat decreased (by 0.9±2.9 kg; p<0.001) by the 6 month. The majority of the patients and their doctors reported the effects of described therapy as "good" or "very good". It is concluded that the substitution of the treatment with insulin detemir in combination with OHGA by therapy with insulin glargine in the patients with DM2 and suboptimal glycemic control under conditions of the routine clinical practice may improve the quality of glycemic control without a substantial body weight gain and with the low frequency of hypoglycemic episodes.

AbstractAim: We evaluated the association between anthropometric parameters and markers of insulin and leptin secretion/resistance in patients with type 2 diabetes mellitus (T2DM).Material and methods: This post-hoc data analysis from a cross-sectional study included 176 T2DM patients. Laboratory tests (serum leptin, soluble form of leptin receptor (sObR), C peptide, glycemic and lipid parameters) and anthropometric parameters were obtained, adiposity indexes (including body adiposity index (BAI), visceral adiposity index (VAI)), indicators of insulin resistance, β-cell function, and leptin resistance (Free Leptin Index, FLI) were calculated.Results: The body mass index (BMI), diabetes duration, VAI and leptin correlated independently with HOMA-IR, while BMI, diabetes duration and HbA1c with HOMA-B. The total body fat mass (TBFM), C peptide, diabetes duration, BMI and BAI correlated with leptin concentrations, while the first three with FLI. VAI was an indicator of insulin resistance (β=0.166, p=0.003), while BAI of leptin secretion (β=0.260, p=0.010). TBFM strongly associated with leptin resistance and secretion (β=0.037, r=0.688, p<0.0001, and β=0.521, r=0.667, p<0.0001), and BMI correlated weakly with insulin secretion and resistance. While insulin and leptin secretion increased progressively with BMI, leptin and insulin resistance became significant only in case of obesity. The sObR was significantly associated with C peptide concentrations (β=-0.032; p=0.044), but not with HOMA-B or -IR. A strong positive correlation between the C peptide/leptin ratio and non-fat mass /TBFM ratio was noted (r=0.62 [0.52, 0.71], p<0.0001).Conclusions: Parameters of peripheral adiposity correlated better with markers of leptin system, and those of visceral adiposity with markers of insulin secretion/resistance. The sObR correlated independently and negatively with C peptide.

It is of interest to evaluate the clinical effectiveness and safety of vildagliptin as monotherapy and combination therapy of vildagliptin and metformin for the management of type 2 diabetes mellitus (T2DM) patients in Indian settings. The study included patients with T2DM (aged >18 years) receiving vildagliptin monotherapy and vildagliptin in combination with metformin therapy of various strengths. Data related to demographics, risk factors, medical history, glycated hemoglobin (HbA1c) levels, and medical therapies were retrieved from medical records. Out of 9678 patients (median age, 52.0 years), 59.1% were men. A combination of vildagliptin and metformin (50/500 mg) was the most commonly used therapy (54.8%), and the median duration of therapy was 24.0 months. The predominant reason for selecting vildagliptin therapy was to improve HbA1c levels (87.8%). A total of 87.5% of patients required dosage up-titration. Vildagliptin therapy was used in patients with T2DM and associated complications (peripheral neuropathy, CAD, nephropathy, retinopathy, autonomous neuropathy, stroke/TIA, and peripheral artery disease). Among 5175 patients who experienced body weight changes, a majority of patients had lost weight (68.6%). The target glycemic control was achieved in 95.3% of patients. The mean HbA1c levels were significantly decreased post-treatment (mean change: 1.34%; p<0.001). Adverse events were reported in 0.4% of patients. Physicians rated the majority of patients as good to excellent on the global evaluation of efficacy and tolerability scale (98.9%, each). Vildagliptin with or without metformin was an effective therapy in reducing HbA1c helps in achieving target glycemic control, and was well-tolerated in Indian patients with T2DM continuum.

Abstract Background:The pathogenesis of type 2 diabetes mellitus is due to two major abnormalities including insulin resistance and dysfunction, which lead to the inability to regulate blood glucose level. Adiponectin is a hormone secreted by the adipose tissue and it takes part in glucose metabolism with insulin-sensitising properties. Low levels of adiponectin leads to reduction of fatty acid oxidation decreased glucose uptake in skeletal muscle cells and increased level of free fatty acids leading to insulin resistance. Leptin is another adipokine produced by adipose tissue involved in the control of food intake via its action on the hypothalamus, suppressing appetite and stimulating energy expenditure. Leptin plays a critical role in pathophysiology of type 2 diabetes mellitus.The aim of the study was to investigate the association of serum adipokines levels with glycemic control and metabolic dyslipidemia in Sudanese patients with type 2 diabetes mellitus.Methods: This was a case control study. 202 patients with type 2 diabetes and 102 non-diabetic controls participated after signing written consent. Weight (kg) and height (m) were measured thenthe body mass index (kg/m2) was determined. Blood samples were collected after an overnight fasting. FBG, HbA1c and lipid profiles were measured using enzymatic methods. Adiponectin and leptin were measured using sandwich ELISA.Results: Adiponectin concentrations was significantly lower in patients with type 2 diabetes compared with the controls (p<0.001) and it was inversely correlated with HbA1c (Pearson Correlation -.160, P value = 0.005), total cholesterol and LDL levels (P = 0.05) and direct correlated HDL levels (P = 0.05). Leptin concentrations was significantly higher in patients with type 2 diabetes compared with the controls (p<0.002) and it was positively correlated with HbA1c (Pearson Correlation .155, P value = 0.02), total cholesterol and LDL levels (P = 0.05), there were no correlation with HDL and TG levels. Patients had significantly higher fasting blood glucose, HbA1c levels, total cholesterol and LDL levels compared with the controls. Conclusion: Patients with type 2 diabetes mellitus had decreased levels of serum adiponectin, high levels of serum leptin. There were significant correlations found between adiponectin and leptin levels with glycemic control and metabolic dyslipidemia

ABSTRACT This systematic review aimed to evaluate the effectiveness and safety of probiotics for glycemic control in adults with impaired glucose control, including prediabetes and type 2 diabetes mellitus (T2DM). We searched PubMed, Embase, and Cochrane databases, and trial registries up to February 2019. We included randomized controlled trials (RCTs) of participants with prediabetes or T2DM. Eligible trials compared probiotics versus either placebo, no intervention, or comparison probiotics, or compared synbiotics versus prebiotics. Primary outcomes were mean change in fasting blood glucose (FBG) and glycated hemoglobin (HbA1c) from baseline to short term (&lt;12 wk) and long term (≥12 wk). We performed meta-analyses using the random-effects model. We included 28 RCTs (1947 participants). Overall, probiotics reduced FBG more than the placebo/no intervention group with a mean difference (MD) of –12.99 mg/dL (95% CI: –23.55, –2.42; P value: 0.016) over the short term; and –2.99 mg/dL (95% CI: –5.84, –0.13; P value: 0.040) over the long term. There was also some evidence for reduced HbA1c in the probiotics group at both short term (MD: –0.17; 95% CI: –0.37, 0.02; P value: 0.084) and long term (MD: –0.14; 95% CI: –0.34, 0.06; P value: 0.172), however, these did not reach statistical significance possibly because only a few trials reported HbA1c as an outcome. Subgroup analyses showed a greater reduction in HbA1c in participants not receiving insulin therapy than those receiving insulin therapy. Furthermore, the effect of probiotics on the reduction of FBG was more pronounced in participants with FBG &gt;130 mg/dL and those not receiving insulin therapy than their counterparts. Probiotics were also effective in lowering serum cholesterol over the short and long term. In conclusion, we found that probiotics may have a glucose-lowering effect in T2DM participants. The effect appeared to be stronger in participants with poorly controlled diabetes and those not on insulin therapy. Systematic review registration: CRD42019121682.

It is hypothesized that under optimal glycemic control (GC), there is no difference in the survival of implants placed in the zygomatic bone of edentulous patient with and without type-2 diabetes mellitus (T2DM). Purpose: The aim was to assess the influence of GC on survival of implants placed in the zygomatic bone of edentulous patient with and without T2DM at 10-years’ follow-up. Twenty patients with T2DM (10 with poorly- and 10 with well-controlled T2DM) and 12 patients without T2DM were included. Hemoglobin A1c (HbA1c) levels were recorded and demographic data was collected from all participants. Peri-implant inflammatory parameters (plaque index [PI], probing depth [PD], crestal bone loss [BL] and gingival index [GI]) were measured in all patients. Group comparisons were done and P-values, which were less than 0.01 were indicative of statistical significance. Twenty and 12 male patients with and without T2DM, respectively were included. Among patients with T2DM, 10 and 10 individuals had poorly- and well-controlled T2DM, respectively.  The mean HbA1c levels were significantly higher in patients with poorly- (9.2 ± 0.7%) compared with well-controlled T2DM (4.8 ± 0.3%) (P&lt;0.01) and non-diabetic individuals (4.6 ± 0.3%) (P&lt;0.01). The crestal BL on the mesial (P&lt;0.01) and distal (P&lt;0.01) surfaces, PD (P&lt;0.01), PI (P&lt;0.01), and GI (P&lt;0.01) were significantly higher around all zygoma implants placed in patients with poorly-controlled T2DM compared with patients with well-controlled T2DM and patients without T2DM. These clinicoradiographic parameters were comparable around zygoma implants placed in patient with well-controlled T2DM and in subjects without T2DM.  Optimal glycemic control is essential for the long-term stability of zygomatic plants in patients with T2DM.

<b><i>Objective:</i></b> To examine whether low baseline diastolic blood pressure (DBP) modifies the effects of intensive systolic blood pressure (SBP) lowering on cardiovascular outcomes in type 2 diabetes mellitus (T2DM). <p><b><i>Research Design and Methods:</i></b> The Action to Control Cardiovascular Risk in Diabetes Blood Pressure trial (ACCORD BP),a 2X2 factorial randomized controlled trial, examined effects of SBP (<120 vs. <140 mmHg) and glycemic (HbA1C < 6% vs. 7.0–7.9% (<42 vs 53-63 mmol/mol)) control on cardiovascular events in T2DM (N=4731). We examined whether effects of SBP control on cardiovascular composite was modified by baseline DBP and glycemic control. </p> <p><b><i>Results: </i></b>Intensive SBP lowering decreased the risk of the cardiovascular composite (HR 0.76, 95% CI 0.59 to 0.98) in the standard glycemic arm but not in the intensive glycemic arm (HR=1.06, 95% CI 0.81 to 1.40). Spline regression models relating the effects of the intervention on the cardiovascular composite across the range of baseline DBP did not show evidence of effect modification by low baseline DBP for the cardiovascular composite in the standard or intensive glycemic arms. The relation between the effect of the intensive SBP intervention and baseline DBP was similar between glycemic arms for the cardiovascular composite (3-way interaction p-value = 0.83).</p> <p><b><i>Conclusions: </i></b>in persons with T2DM, intensive SBP lowering decreased the risk of cardiovascular composite endpoint irrespective of baseline DBP in the setting of standard glycemic control. Hence, low baseline DBP should not be an impediment to intensive SBP lowering in T2DM patients treated with guidelines recommended standard glycemic control. </p>
