Item Sodium glucose co-transporter 2 inhibitors in heart failure therapy(2020) Cavusoglu, Yuksel; Altay, Hakan; Cahn, Avivit; Celik, Ahmet; Demir, Serafettin; Kilicaslan, Baris; Nalbantgil, Sanem; Raz, Itamar; Temizhan, Ahmet; Yildirimturk, Ozlem; Yilmaz, Mehmet Birhan; AAE-1392-2021; 32281958Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are a new class of drugs for patients with type 2 diabetes (T2DM) which inhibit urinary glucose reabsorption in the proximal tubule of the nephron and result in glucosuria, natriuresis and diuresis. In large, randomized clinical trials, SGLT-2i have been shown to reduce major cardiovascular (CV) events and heart failure (HF) hospitalizations in patients with T2DM who have atherosclerotic CV disease or CV risk factors. In these trials, SGLT-2i is have their greatest and most consistent effect on reducing the risk of HF hospitalization. The reduction in HF hospitalization was also observed in subgroups of patients with a HF diagnosis at baseline, which raised the possibility of a clinical benefit of SGLT-2i in HF patients, regardless of the presence or absence of T2DM. In very recently published DAPA-HF trial, a SGLT-2i, dapagliflozin treatment on top of standard HF therapy has been shown to have clear clinical benefits in terms of reducing HF hospitalization, CV mortality, all-cause mortality and improving quality of life in HF patients. This compelling evidence suggests that SGLT-2i have a potential to be an effective treatment option in HF, regardless of diabetes. This article provides a comprehensive overview focused on the role of SGLT-2i in the treatment of HF.Item Evaluation of the Relationship between Type II Diabetes Mellitus and the Prevalence of Apical Periodontitis in Root-Filled Teeth Using Cone Beam Computed Tomography: An Observational Cross-Sectional Study(2019) Sisli, Selen Nihal; 30999319Objective: This study aimed to investigate the prevalence of apical periodontitis (AP) in patients with type II diabetes mellitus (DM) with either optimal glycemic control (OGC) or poor glycemic control (PGC) compared with nondiabetics using cone beam computed tomography (CBCT). Subjects and Methods: The periapical status of 75 teeth with adequate root canal treatment performed at least 1 year ago that could be visualized in the field of view of CBCT images of 43 DM patients (29 females, 14 males) was compared with a control group consisting of 162 teeth of 86 nondiabetics (56 females, 30 males). In addition, the DM group was divided into subgroups according to the patients' mean glycated hemoglobin level as either having OGC or PGC. The periapical status of the teeth was evaluated using the CBCT periapical index (CBCTPAI), and AP was diagnosed as a CBCTPAI >= 1. chi(2), Fisher's exact test, and independent-samples t tests were used for the statistical analysis, and p < 0.05 was considered significant. Results: Significant differences between the DM group and the control group were observed (p< 0.05) in terms of AP (the frequencies of both CBCTPAI >= 1 and CBCTPAI >= 3) and the frequency of cardiovascular disease, while there were no significant differences between the DM subgroups (p > 0.05). Conclusion: The prevalence of AP and severe bone destruction in periapical tissues was significantly higher in the DM patients compared with the nondiabetic patients.Item Diabetes and cardiac autonomic neuropathy: Clinical manifestations, cardiovascular consequences, diagnosis and treatment(2015) Balcioglu, Akif Serhat; Muderrisoglu, Haldun; 25685280Cardiac autonomic neuropathy (CAN) is a frequent chronic complication of diabetes mellitus with potentially life-threatening outcomes. CAN is caused by the impairment of the autonomic nerve fibers regulating heart rate, cardiac output, myocardial contractility, cardiac electrophysiology and blood vessel constriction and dilatation. It causes a wide range of cardiac disorders, including resting tachycardia, arrhythmias, intraoperative cardiovascular instability, asymptomatic myocardial ischemia and infarction and increased rate of mortality after myocardial infarction. Etiological factors associated with autonomic neuropathy include insufficient glycemic control, a longer period since the onset of diabetes, increased age, female sex and greater body mass index. The most commonly used methods for the diagnosis of CAN are based upon the assessment of heart rate variability (the physiological variation in the time interval between heartbeats), as it is one of the first findings in both clinically asymptomatic and symptomatic patients. Clinical symptoms associated with CAN generally occur late in the disease process and include early fatigue and exhaustion during exercise, orthostatic hypotension, dizziness, presyncope and syncope. Treatment is based on early diagnosis, life style changes, optimization of glycemic control and management of cardiovascular risk factors. Medical therapies, including aldose reductase inhibitors, angiotensin-converting enzyme inhibitors, prostoglandin analogs and alpha-lipoic acid, have been found to be effective in randomized controlled trials. The following article includes the epidemiology, clinical findings and cardiovascular consequences, diagnosis, and approaches to prevention and treatment of CAN.Item Serum cystatin C and neutrophil gelatinase-associated lipocalin in predicting the severity of coronary artery disease in diabetic patients(2016) Okyay, Kaan; Yildirir, Aylin; Cicek, Mutlu; Aydinalp, Alp; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0001-8750-5287; 0000-0002-3761-8782; 0000-0001-6134-8826; 27182610; AAG-8233-2020; A-4947-2018; AAD-5841-2021; AAK-7355-2020Objective: Cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) are biomarkers of renal functions. We evaluated their roles in predicting the severity of coronary artery disease (CAD). Methods: Fifty-two consecutive type 2 diabetic patients (32 males, 65.7 +/- 8.6 years) who underwent coronary angiography (CAG) for stable CAD were included in this single-center, prospective, cross-sectional study. Patients with an estimated glomerular filtration rate <60mL/min/1.73m(2) and with a history of by-pass surgery and/or coronary stent implantation were excluded. The vessel score and Gensini score were calculated to assess the presence and severity of CAD. Mann-Whitney U test, Spearman test, and multiple linear regression analysis were used for the main statistical analyses. Results: Serum cystatin C levels were higher in patients with multivessel disease than in those with single vessel disease [1260 ng/mL (953-1640) vs. 977 ng/mL (599-1114), p=0.017]. According to the median Gensini score, the higher score group also had higher cystatin C levels than the lower score group [1114 ng/mL (948-1567) vs. 929 ng/mL (569-1156), p=0.009]. However, serum NGAL levels were similar between these subgroups. There was a positive correlation between cystatin C and Gensini score (r=0.334, p=0.016). Multiple linear regression analysis revealed serum cystatin C as an independent predictor of the Gensini score (beta=0.360, t=2.311, p=0.026). These results may aid in defining cystatin C as a surrogate marker of the extent of CAD in further clinical trials. Conclusion: Serum Cystatin C, but not NGAL levels, could predict the severity of CAD in diabetic patients.
