Objective: In this study we aimed to investigate the efficacy and safety of dapagliflozin addition to diabetic patients using high dose insulin. Methods: The current study was carried out in the outpatient diabetic clinics of Fatih Sultan Mehmet Education and Research Hospital. Thirty diabetic patients who were receiving high dose (>0.5U/kg) insulin and oral antidiabetic treatment (other than SGLT 2 inhibitors) were included in this study. Primary end point was the change in HbA1c, insulin doses and serum electrolyte from the addition of dapagliflozin 10 mg to the week 12. Results: At the end of three month BMI were obviously decreased from 33.31±4.51 to 32.14±4.66 (p: 0.001). There was also an evident decrease of insulin requirement from 76±23.15 U/kg to 57.60±17.61 U/day (p<0.001). As well as the decrease in insulin doses, there was also a significant decline in HbA1c (Δ 1.6 %) and fasting blood glucose levels (Δ68.6 mg/dl) (p<0.001). Among serum electrolyte levels slight but meaningful increase of blood urea nitrogen (BUN) and sodium (Na) levels were seen (p: 0.044 and p: 0.026). There were no significant changes in serum cholesterol levels with electrolytes such as potassium, calcium, phosphorus magnesium and vitamin D (p>0.05). Conclusion: In diabetic patients with inadequately controlled glucose regulation despite high-dose insulin therapy, dapagliflozin may be an alternative combination choice to decrease the need of insulin dose and obtain an optimal HbA1c, fasting plasma glucose levels and weight without major side effects.

IntroductionDiabetes mellitus (DM) is a metabolic disorder associated with both microvascular and macrovascular complications. Mean platelet volume (MPV) is a marker of platelet activity, which plays a major role in the development of vascular complications of DM. The aim of this study is to compare the MPV levels before and after the decrease of glycated hemoglobin (HbA1c) levels in a large diabetic population.Material and methodsThis was a retrospective study conducted on type 2 diabetic patients from the outpatient clinic for 1 year between 2014 and 2015 with the participation of 595 diabetic patients.ResultsWhen we compared the basal and post-treatment values, a significant decrease of MPV and HbA1c levels was found (HbA1c: 9.41 ±1.98% vs. 7.43 ±1.29%, p < 0.001; MPV: 9.11 ±1.42 vs. 8.17 ±1.04, p < 0.001). There was also a positive correlation between the mean changes of MPV and HbA1c levels after the treatment (ΔMPV: 0.93 ±0.96 vs. ΔHbA1c: 1.96 ±1.43; p = 0.005, r = 0.115). When the participants were divided into two groups according to their basal HbA1c levels (group A: HbA1c ≤ 6.5% and group B: HbA1c > 6.5%), it was clearly seen that improvement of glucose levels led to a significant decrease in MPV levels in both groups.ConclusionsThe results of this study show that better glycemic control is associated with a significant decrease of MPV levels, regardless of whether the treatment modality is insulin or oral antidiabetic.

INTRODUCTION Diabetes and its complications are the significant cause of morbidity and mortality. Advanced glycation end products play a major role in the pathogenesis of diabetes complications. OBJECTIVES The aim of the study was to investigate the possible use of a biomicroscope (ClearPath DS-120), which shows the age-adjusted lens fluorescence ratio (LFR), for the diagnosis of diabetic peripheral neuropathy (DPN). PATIENTS AND METHODS A total of 160 patients with type 2 diabetes who underwent an LFR measurement were recruited to this study. DPN was defined as the presence of neuropathic pain or feet sensory loss (or both). Neurothesiometer, monofilament test, and DN4 test results were used for the diagnosis of DPN. RESULTS The LFR of 43 patients (27%) was higher than the expected levels. According to the DN4 questionnaire, 35 of 160 patients (21%) had neuropathic pain. Thirty-seven patients (23%) had higher vibration perception thresholds than expected (>25 V). The monofilament test showed that 42 patients (26%) seemed to be affected by DPN. All of the tests, when considered individually, revealed that patients with higher LFR had more problems related to DPN (P <0.05). High LFR had a sensitivity of 50% and a specificity of 81% in the diagnosis of DPN. Although there was no significant difference in fasting blood glucose levels, we observed that HbA 1c levels were higher and diabetes duration was longer in patients with higher LFR (P <0.05). CONCLUSIONS The measurement of LFR may have clinical utility for a noninvasive detection of DPN.

Purpose/Background: Glucagon-like peptide-1 (GLP-1) is a molecule used to treat type 2 diabetes mellitus (T2DM). Given their widespread expression in the nervous system, GLP-1 receptors also play a role in regulating mood and cognitive function. Here, we aimed to compare obese patients with T2DM, with or without exenatide (a GLP-1R agonist) use on cognitive and affective functioning. Methods/Procedures: A total of 43 patients with T2DM (23 on exenatide and 20 without exenatide) were evaluated with the Snaith-Hamilton Pleasure Scale, Cognitive Failures Questionnaire, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7, Childhood Trauma Questionnaire, Perceived Stress Scale (PSS), and Chronic Stress Scale, in addition to laboratory-based measures of reward learning (the probabilistic reward task) and working memory (Letter-N-Back task).Findings/Results: Patients on exenatide had higher body mass index (

The activation of the platelets plays a key role in the formation of thrombosis. The variables such as mean platelet volume, platelet factor 4 and β-thromboglobulin have been used in the demonstration of the platelet activation. However, when the literature was reviewed, there was not found any study investigating the level of β-thromboglobulin in patients with rheumatoid arthritis. Our goal is to evaluate the β-thromboglobulin levels together with mean platelet volume in patients with arthritis. This study is a clinical study which has a control group that has been designed prospectively, and in this study, Rheumatology Outpatient Clinic follow-up patients with rheumatoid arthritis and healthy control group were studied. All patients and healthy volunteers were examined β-thromboglobulin and mean platelet volume. Twenty-two patients with rheumatoid arthritis and 21 healthy volunteers participated in the study. β-Thromboglobulin mean was found as 98.00 ± 60.49 ng/mL in rheumatoid arthritis group and it was 62.38 ± 30.41 ng/mL in healthy control group. The differences between these groups were significant in terms of the levels of β-thromboglobulin (p = 0.02). We found significant differences between the groups in terms of mean platelet volume (p = 0.049). In this study, the level of β-thromboglobulin was found significantly higher in patients with rheumatoid arthritis, which is a chronic inflammatory disease. This result could be an indicator, such as platelet activation in patients with rheumatoid arthritis, or it may be a helper marker in the follow-up and treatment of developing cardiovascular risk.
