Publication Open Access CD40 ligand and P-selectin in heterozygous Beta-thalassemia(2016-06-01) CIKRIKCIOGLU, Mehmet Ali; SOYTAS, Rabia Bag; KILIC, Elif; Toprak, Aybala Erek; Karatoprak, CUMALİ; Zorlu, MEHMET; Kiskac, MUHARREM; EMEGIL, Sebnem; Cetin, GÜVEN; Dogan, ELİF ECE; SEKIN, Yahya; HAMDARD, Jamshid; ÇAKIRCA, MUSTAFA; ZORLU, MEHMET; KISKAÇ, MUHARREM; ÇETİN, GÜVEN; DOĞAN, ELİF ECE; KARATOPRAK, CUMALİObjective: To investigate platelet functions and measure soluble CD40 ligand, soluble P-selectin, beta-thromboglobulin and platelet factor 4 levels in the blood of heterozygous beta thalassemia patients. Methods: The cross-sectional case-control study was conducted at Bezmialem Vakif University, Istanbul, Turkey, between September 2013 and April 2014, and comprised heterozygous beta thalassemia patients who were compared with 41 gender-, age- and body mass index-matched controls for platelet function markers. The two groups were also compared for co-morbidities, smoking, and regular medications. Results: Of the 78(78.78) subjects, 50(64%) were women and 28(36%) men with an overall mean age of 39.4±12.7 years (range: 18-79 years). The mean body mass index was 26.3±4.2. The heterozygous beta thalassemia group included 37(47%) subjects [24(65%) females; 13(35%) males] while the control group had 41(53%) [26(63%) females; 15(37%) males]. Soluble CD40 ligand and soluble P-selectin were lower in the heterozygous beta thalassemia group (p=0.009; p=0.010). Beta-thromboglobulin and platelet factor 4 levels were comparable between the groups (p=0.497; p=0.507.). Conclusions: Some platelet functions may be reduced in heterozygous beta thalassemia patients, which may be related to their lower incidence of cerebral and cardiac ischaemic events.Publication Open Access Serum endocan levels in women with restless legs syndrome.(2015-11-19) CELIK, K; ÇıKRıKÇıOĞLU, MA; HALAC, G; KILIC, ERDEM; AYHAN, S; OZARAS, N; Karatoprak, CUMALİ; YILDIZ, KEMALETTİN; YILDIZ, RS; ZORLU, MEHMET; CAKIRCA, MUSTAFA; KıSKAÇ, MUHARREM; KILIÇ, ERDEM; YILDIZ, KEMALETTİN; ZORLU, MEHMET; KARATOPRAK, CUMALİ; ÇAKIRCA, MUSTAFA; KISKAÇ, MUHARREMBackground: Endocan is a recently introduced marker of endothelial dysfunction. The objective of this study was to compare serum endocan levels in patients with restless legs syndrome (RLS) and control subjects in order to elucidate whether RLS is associated with endothelial dysfunction. Methods: A total of 31 drug naïve female patients with RLS and 31 age- and BMI-matched women were included in the study. Patients with pathological or physiological conditions or with a history of medication use that could potentially influence endothelial functions were excluded, as well as those with alcohol or drug abuse history. The two groups were compared with routine blood tests and serum endocan levels. Results: Patients with RLS had lower serum endocan levels than the controls (P=0.037). There was a negative bivariate correlation between RLS severity score and serum endocan levels (r=-0.406, P=0.023). While white blood cell count was significantly higher in RLS group, 25-hydroxy vitamin D3, vitamin B12, transferrin saturation rate, and HDL-cholesterol were significantly lower. Creatininemia and diastolic blood pressure were also marginally insignificantly lower in RLS group. Due to the presence of differences between two groups in these variables, a linear regression analysis was performed that showed a positive association between endocan and creatininemia (β=0.310, P=0.022), and a negative association between endocan and RLS (β=-0.502, P,0.001). Conclusion: The results of this study seem to suggest that patients with RLS may have better endothelial functions when compared with the general population and that these patients may be better protected against atherosclerosisPublication Open Access Association of calcium channel blocker use with lower hemoglobin levels in chronic kidney disease(2013-09-01) Karatoprak, CUMALİ; CIKRIKCIOGLU, M. A.; Cakirca, MUSTAFA; Kiskac, MUHARREM; Zorlu, MEHMET; Cetin, GÜVEN; YILDIZ, KEMALETTİN; ERKOC, R.; ALAY, M.; Erkal, S.; Erkal, S. N.; DOGAN, S.; Kazancioglu, RÜMEYZA; KARATOPRAK, CUMALİ; ÇAKIRCA, MUSTAFA; KISKAÇ, MUHARREM; ZORLU, MEHMET; ÇETİN, GÜVEN; YILDIZ, KEMALETTİN; KAZANCIOĞLU, RÜMEYZAAim: To search whether calcium channel blockers (CCBs) are associated with lower hemoglobin levels in chronic kidney disease (CKD) patients who are not on renal replacement therapy (RRT), vitamin D and anti-anemic treatment. Patients and methods: CKD patients were classified into two groups. Patients on CCBs treatment (103 patients) and patients not using CCBs (104 patients) were compared cross-sectionally regarding clinical findings, complete blood count (CBC), biochemistry and regular medication use. Patients with polycystic kidney disease, comorbidities that could influence CBC other than iron deficiency of obscure origin, patients receiving RRT, erythropoietin (EPO), vitamin D, phosphate binders and drugs that could influence CBC were excluded. Under dependent variable of CCB use, all significantly different independent variables were subjected to multivariate binary logistic regression analysis (MBLRA). Results: Lower hemoglobin, lower bilirubinemia, higher serum EPO, higher systolic blood pressure were observed in CCB users. Two groups were similar concerning age, gender, BMI, CKD etiology, CKD stage, pretibial edema prevalence, cardiothoracic index, diastolic blood pressure, corrected reticulocyte count, BUN, creatinine, eGFR, proBNP, parathormone, alkaline phosphatase, phosphorous, corrected calcemia, sCRP, relative EPO deficiency and prevalence of relative EPO deficient patients. Groups were comparable regarding comorbidities, types and usage frequencies of all antihypertensive medications other than CCBs. Higher systolic blood pressure and lower hemoglobin were significantly associated with CCB use after MBLRA. Conclusions: Hemoglobin was significantly lower in CCB users compared to non-users, among CKD patients who did not receive RRT, EPO, phosphate binders, vitamin D, iron, vitamin B12 and folic acid.Publication Metadata only A case of rhabdomyolysis complicated with acute renal failure after resumption of fenofibrate therapy: a first report.(2013-05-01) KıSKAÇ, MUHARREM; ZORLU, MEHMET; CAKIRCA, MUSTAFA; Karatoprak, CUMALİ; PERU, C; ERKOÇ, R; YAVUZ, E; KISKAÇ, MUHARREM; ZORLU, MEHMET; ÇAKIRCA, MUSTAFA; KARATOPRAK, CUMALİPublication Metadata only Effects of 18-Month Vildagliptin Treatment on Portal Vein Pressure(2015-06-01) Karatoprak, CUMALİ; KILICARSLAN, Rukiye; Cakirca, MUSTAFA; Aydin, SİNEM; OZKAN, Tuba; KOCAMAN, Orhan; YOLBAS, Servet; Zorlu, MEHMET; Kiskac, MUHARREM; CIKRIKCIOGLU, Mehmet Ali; KOCAKOC, Ercan; ERKOC, Reha; KARATOPRAK, CUMALİ; ÇAKIRCA, MUSTAFA; AYDIN, SİNEM; ZORLU, MEHMET; KISKAÇ, MUHARREMPublication Open Access Vildagliptin Treatment on the Portal Venous Pressure and Hepatosteatosis in Patients with Type 2 Diabetes Mellitus(2018-01-01) Kilicarslan, Rukiye; Cakirca, MUSTAFA; Aydin, SİNEM; OZKAN, Tuba; KOCAMAN, Orhan; Yolbas, Servet; Zorlu, MEHMET; Karatoprak, CUMALİ; Kiskac, MUHARREM; CIKRIKCIOGLU, Mehmet Ali; ERKOC, Reha; KARATOPRAK, CUMALİ; ÇAKIRCA, MUSTAFA; AYDIN, SİNEM; ZORLU, MEHMET; KISKAÇ, MUHARREMObjective: This study investigated how vildagliptin (a di-peptidyl peptidase 4 inhibitor) affects portal vein pressure and hepatosteatosis in patients with type 2 diabetes mellitus.Publication Open Access GAS6 intron 8 c.834 + 7G > A gene polymorphism in diabetic nephropathy.(2015-06-01) ERKOÇ, R; ÇıKRıKÇıOĞLU, MA; AINTAB, E; TOPRAK, ALİ; KILIC, U; GOK, O; CETIN, AI; ZORLU, MEHMET; KıSKAÇ, MUHARREM; CAKIRCA, MUSTAFA; Karatoprak, CUMALİ; ISEN, HC; ZORLU, MEHMET; KISKAÇ, MUHARREM; ÇAKIRCA, MUSTAFA; KARATOPRAK, CUMALİBackground - Aim: In animal experiments, growth arrest-specific 6 (Gas6) protein plays a key role in the development of mesangial cell and glomerular hypertrophy in the early phase of diabetic nephropathy, and diabetic nephropathy is prevented by warfarin-induced inhibition of GAS6 protein. It was shown that GAS6 intron 8 c.834+7G>A polymorphism is protective against type 2 diabetes mellitus, and AA genotype is associated with higher blood levels of GAS6 protein. Our aim is to investigate whether this polymorphism is a risk factor for diabetic nephropathy in type 2 diabetes mellitus. Method: Eighty-seven patients with diabetic nephropathy were compared with 66 non-diabetic controls in terms of GAS6 intron 8 c.834+7G>A polymorphism. Patients with history of stroke, ischemic heart disease were excluded. Each patient was examined by the ophthalmologist to determine diabetic retinopathy. Results: Frequency of GG, GA and AA genotypes are similar in diabetic nephropathy and control groups according to GAS6 intron 8 c.834+7G>A polymorphism (p = 0.837). Rate of diabetic retinopathy was 54.02%. In the subgroup analysis, GA genotype was significantly more frequent than GG genotype in patients with diabetic retinopathy when compared to without diabetic retinopathy (p = 0.010). Conclusion: In our study, GAS6 intron 8 c.834+7G>A polymorphism was not associated with diabetic nephropathy in type 2 diabetes mellitus. However, heterozygous state of this polymorphism may be a risk factor for diabetic retinopathy in patients with diabetic nephropathy.Publication Metadata only Reduced bone resorption and increased bone mineral density in women with restless legs syndrome.(2016-03-29) ÇıKRıKÇıOĞLU, MA; SEKIN, Y; HALAC, G; Karatoprak, CUMALİ; KESGIN, S; AYDIN, S; OZARAS, N; AKAN, O; CELIK, K; HAMDARD, J; ZORLU, MEHMET; CAKIRCA, MUSTAFA; KıSKAÇ, MUHARREM; KILIÇ, ERDEM; ZORLU, MEHMET; KARATOPRAK, CUMALİ; ÇAKIRCA, MUSTAFA; KISKAÇ, MUHARREMPublication Open Access Evaluation of the Relation between Vitamin D and Serum Omentin and Vaspin Levels in Women(2016-07-01) Zorlu, MEHMET; Kiskac, MUHARREM; Cakirca, MUSTAFA; Guler, E.
