    Aims: Turkey has the highest prevalence of diabetes in Europe. It is therefore essential to know the overall cardiovascular risk and reveal the predictors of metabolic control in Turkish adults with diabetes mellitus. Methods: A nationwide, multicenter survey consecutively enrolled patients who were under follow up for at least a year. Optimal control was defined as HbA1c < 7%, home arterial blood pressure (ABP) < 135/85 mmHg, or LDL-C < 100 mg/dL. Achieving all parameters indicated triple metabolic control. Results: HbA1c levels of patients (n = 5211) were 8.6 ± 1.9% (71 ± 22 mmol/mol) and 7.7 ± 1.7% (61 ± 19 mmol/mol), in Type 1 and Type 2 diabetes, respectively. Glycemic control was achieved in 15.3% and 40.2%, and triple metabolic control was achieved in 5.5% and 10.1%, respectively. Only 1.5% of patients met all the criteria of being non-obese, non-smoker, exercising, and under triple metabolic control. Low education level was a significant predictor of poor glycemic control in both groups. Conclusions: Few patients with Type 2, and even fewer with Type 1 diabetes have optimal metabolic control in Turkey. TEMD study will provide evidence-based information to policy makers to focus more on the quality and sustainability of diabetes care in order to reduce the national burden of the disease. © 2018 Elsevier B.V.

    AT-101 acts as anti-proliferative and hormone suppressive agent in mouse pituitary corticotroph tumor cells
    (Springer International Publishing, 2018) Yurekli B.S.; Karaca B.; Kisim A.; Bozkurt E.; Atmaca H.; Cetinkalp S.; Ozgen G.; Yilmaz C.; Uzunoglu S.; Uslu R.; Saygili F.
    Purpose: Gossypol, a naturally occurring compound in cottonseeds, has anticancer effects against several tumor cell lines. It has been extensively studied in clinical trials and is well tolerated with a favorable safety profile. AT-101, a derivative of R (−)-gossypol, binds to Bcl-2 family proteins and induces apoptosis in vitro. Although transsphenoidal surgical excision of the pituitary corticotroph adenoma is the gold standard of care, it is not successful all the time. Medical therapy for Cushing’s disease still remains a challenge for the clinicians. We aimed to investigate the cytotoxic and apoptotic effects of AT-101 in mouse pituitary corticotroph tumor AtT20 cells. Methods: Cytotoxic effect of AT-101 was assessed by XTT cell viability assay. Apoptosis was shown by measuring DNA fragmentation and Caspase-3/7 activity. Changes in mRNA expressions of apoptosis-related genes were investigated by qPCR array after treatment with AT-101. ACTH was measured by ACTH-EIA Kit. Results: AT-101 induced cytotoxicity and apoptosis in AtT20 cells. mRNA levels of pro-apoptotic genes such as TNFR-SF-10B, Bid, PYCARD, Caspase-8, Caspase-3, and Caspase-7 were induced by 2.0-, 1.5-, 1.7-, 1.5-, 1.6-, and 2-fold, respectively, in AtT20 cells by AT-101 treatment. Moreover, some of the anti-apoptotic genes such as BCL2L10, NAIP1, and PAK-7 were reduced by 2.1-, 2.3-, 4.0-fold, respectively, in AtT20 cells. AT-101 also decreased ACTH secretion significantly. Conclusion: AT-101 induces apoptosis in mouse pituitary corticotroph tumor cells. © 2017, Italian Society of Endocrinology (SIE).

    Utilization of statins and LDL-cholesterol target attainment in Turkish patients with type 2 diabetes - a nationwide cross-sectional study (TEMD dyslipidemia study)

    Background: Attaining acceptable levels of LDL Cholesterol (LDL-C) significantly improves cardiovascular (CV) outcomes in patients with type 2 diabetes mellitus (T2DM). The LDL-C target attainment and the characteristics of patients attaining these targets were investigated in this study. Furthermore, the reasons for not choosing statins and the physicians’ attitudes on the treatment of diabetic dyslipidemia were also examined. Methods: A nationwide, cross-sectional survey was conducted in tertiary centers for diabetes management. Adult patients with T2DM, who were under follow-up for at least a year in outpatient clinics, were consecutively enrolled for the study. LDL-C goals were defined as below 70 mg/dL for patients with macrovascular complications or diabetic nephropathy, and below 100 mg/dL for other patients. Data about lipid-lowering medications were self-reported. Results: A total of 4504 patients (female: 58.6%) were enrolled for the study. The mean HbA1c and diabetes duration was 7.73 ± 1.74% and 10.9 ± 7.5 years, respectively. The need for statin treatment was 94.9% (n = 4262); however, only 42.4% (n = 1807) of these patients were under treatment, and only 24.8% (n = 448) of these patients achieved LDL-C targets. The main reason for statin discontinuation was negative media coverage (87.5%), while only a minority of patients (12.5%) mentioned side effects. Physicians initiated lipid-lowering therapy in only 20.3% of patients with high LDL-C levels. It was observed that the female gender was a significant independent predictor of not attaining LDL-C goals (OR: 0.70, 95% CI: 0.59–0.83). Conclusions: Less than 50 % of patients with T2DM who need statins were under treatment, and only a quarter of them attained their LDL-C targets. There exists a significant gap between the guideline recommendations and the real-world evidence in the treatment of dyslipidemia in T2DM. © 2020, The Author(s).
