    Left Ventricle Geometry Affects Coronary Flow Reserve in Diabetic Patients
    (2015) Kalkan, Gulhan Yuksel; Gur, Mustafa; Elbasan, Zafer; Baykan, Ahmet Oytun; Kuloglu, Osman; Sahin, Durmus Yildiray; Seker, Taner; Haydardedeoglu, Filiz Eksi; Sen, Omer; Ucar, Hakan; Kirim, Sinan; Cayli, Murat; 0000-0002-0179-9673; 25655851; AAK-5003-2021
    Objectives: The aim of this study was to investigate the association between coronary flow reserve (CFR) and left ventricle (LV) geometric patterns in patients with newly-diagnosed diabetes mellitus (DM). Study design: We studied 116 patients with newly-diagnosed DM and 31 healthy control subjects. Echocardiographic examination was performed on all subjects. Four different geometric patterns were identified in diabetic patients, according to LV mass index (LVMI) and relative wall thickness (RWT) [NG: Normal geometry; CR: Concentric remodeling; EH: Eccentric hypertrophy; CH: Concentric hypertrophy]. CFR was calculated as the hyperemic to resting coronary diastolic peak velocities ratio. Results: Compared with controls, CFR was decreased in diabetic patients (p<0.05). The lowest CFR values were observed in the CH group compared with control and other groups (p<0.05, for all). Also, CFR values of the CR and EH groups were lower than NG and the control group (p<0.05, for all). CFR was associated with LV geometry (r=-0.449, p=0.001), LVMI (r=-0.401, p<0.001), RWT (r=-0.247, p=0.008), HbA1c (r=-0.576, p<0.001) and mitral valve E/A ratio (r=0.239, p=0.01) in bivariate analysis. CFR was independently associated with LV geometry (beta=-0.449, p<0.001), LVMI (beta=-0.192, p=0.016), and HbA1c (beta=-0.576, p<0.001) in multivariate analysis. Conclusion: CFR was impaired in newly-diagnosed DM. The degree of this deformation increases from normal geometry towards to concentric hypertrophy. This condition suggests that myocardial structural remodeling due to diabetes might be effective on CFR.

    Effect of type 2 diabetes mellitus on efficacy and safety of therapeutic apheresis for severe hypertriglyceridemia
    (2020) Bagir, Gulay Simsek; Bakiner, Okan Sefa; Haydardedeoglu, Filiz Eksi; Araz, Filiz; Ertorer, Melek Eda; Kozanoglu, Ilknur; 0000-0001-7357-8709; 0000-0002-5268-1210; 0000-0003-0780-5680; 0000-0002-0179-9673; 33098371; AAK-5525-2021; ABI-3393-2020; ABI-3705-2020; AAE-1241-2021; AAJ-9184-2021; AAK-5003-2021
    The efficacy and safety of triglyceride (TG) apheresis in patients with type 2 diabetes mellitus (DM) is unclear. Diabetic complications may predispose patients to adverse events (AEs) associated with the apheresis procedure, and diabetic dyslipidemia may negatively affect the efficacy of therapeutic apheresis (TA). We investigated the effect of DM on the efficacy and complications of TA. Patients with severe hypertriglyceridemia who underwent apheresis for treatment or for the prevention of acute pancreatitis were included in this retrospective study. Epidemiological data, lipid parameters, and AEs were recorded before and after each therapeutic session. A total of 166 procedures were performed in 27 patients. Group 1 included 17 patients with type 2 DM, and Group 2 included 10 patients without DM. The mean percentage decrease in TG levels (TG%) was higher in Group 1 (71.9% vs 60.6%, P < .001). The TG% was negatively correlated with the duration of DM in Group 1 (r = -.49, P < .001). The total number of TA sessions was 142 in patients who underwent double filtration plasmapheresis and 24 in patients who underwent therapeutic plasma exchange. We observed 9 (5.4%) mild-to-moderate AEs. No intergroup difference was observed in the total number of AEs (P = .06). TA is safe and effective in patients with type 2 DM with severe hypertriglyceridemia.
