Öğe Association of Severity of Coronary Lesion with Markers of Acute Infection and Inflammation in Patients with Acute Coronary Syndrome(2016) Koçak, Sedat; Dündar, Zerrin Defne; Harmankaya, Atıf; Erdemir, Esma; Keşli, Recep; Alibasic, HayrudinAim: Inflammation and some infectious agents play a key role in acute coronary syndrome (ACS) caused by atherosclerosis. The purpose of this study was to assess the effects of inflammatory markers and the positivity of Chlamydia pneumoniae (CP), Helicobacter pylori (HP), and Cytomegalovirus (CMV) on the level of atherosclerosis in patients with ACS. Materials and Methods: Patients (57) that were referred to the emergency unit with classic angina symptoms or angina equivalent symptoms and were determined to have critical lesions in the coronary angiography (<70% stenosis, coronary artery disease (CAD) severity assessed by the Gensini score) were compared with 27 ACS patients who had no critical lesions in terms of procalcitonin (PCT), tumor necrosis factor-alpha (TNF-?), interleukin-2 receptor (IL2r), interleukin-6 (IL-6), and interleukin-10 (IL-10) levels and positivity of CP, HP, and CMV. Also, the two groups of ACS patients were compared in terms of cytokine levels measured at hours 0 and 48. Results: No significant association was found between the degree of the coronary lesion and the inflammatory and infectious agents. However, in patients with critical coronary lesions, as markers of inflammatory agents, the levels of IL-6 were significantly lower and levels of IL-10 were significantly higher (p>0.001 and p0.030, respectively) at hour 48 than originally found at hour 0. Conclusion: There is no association between the severity of coronary lesions and cytokine levels and positivity of infectious agents in ACS since the levels of proinflammatory cytokines in ACS are higher than those in atherosclerosis. The changes in cytokine levels at hour 48 were found to be significant.Öğe Colchicine Toxicity in End-Stage Renal Disease Patients: A Case-Control Study(Lippincott Williams & Wilkins, 2014) Solak, Yalcin; Atalay, Huseyin; Biyik, Zeynep; Alibasic, Hayrudin; Gaipov, Abduzhappar; Guney, Figen; Kucuk, AdemColchicine has been used in a number of disorders. Because colchicine is partially excreted from the kidney, there is a need for dose reduction in case of renal functional impairment. There are no data with regards to safe dosing schedule of colchicine in hemodialysis patients. We aimed to evaluate adverse effects of colchicine use in a hemodialysis cohort. We screened hemodialysis patients who were using colchicine for any reason. All patients were interviewed regarding possible toxicities of colchicine use and were examined with a special focus on neuromuscular system. Creatine kinase and myoglobin were used to detect any subclinical muscle injury or rhabdomyolysis, respectively. Twenty-two maintenance hemodialysis patients who were on colchicine for more than 6 months and 20 control hemodialysis patients not using colchicine were included in the study. Four of 22 patients were using 0.5 mg/day, 4 patients were using 1.5 mg/day, and 14 patients were using 1 mg/day colchicine. Mean duration for colchicine use was 8.9 +/- 8.2 years. There was no difference between the groups in terms of myoneuropathic signs and symptoms and blood counts except for white blood cell count, which was significantly higher in patients on colchicine. Serum creatine kinase (56.3 +/- 39.5 and 52.1 +/- 36.1 for colchicine and control groups, respectively, P = 0.72) and myoglobin (191.4 +/- 108.8 and 214.6+/-83.5 for colchicine and control groups, respectively, P = 0.44) levels were not different between the groups. We conclude that in a small number of haemodialysis patients who were apparently tolerating colchicine, detailed assessment revealed no evidence of sublinical toxicity when compared with controls.Öğe Corelation Between the 24-Hour Urine Aldosterone Levels and Atrial Electromechanical Conduction Time(Elsevier Science Inc, 2013) Soylu, Ahmet; Alibasic, Hayrudin; Yildirim, Elif; Toker, Aysun; Erdogan, Halil Ibrahim; Duzenli, Mehmet Akif; Tokac, Mehmet[Abstract Not Availabe]Öğe Effect of serum uric acid on the positive predictive value of dobutamine stress echocardiography(Springer, 2016) Aribas, Alpay; Akilli, Hakan; Kayrak, Mehmet; Alibasic, Hayrudin; Yildirim, Oguzhan; Sertdemir, Ahmet Lutfi; Karanfil, MustafaThere is controversial data regarding the relationship between uric acid (UA) and coronary artery disease and cardiovascular events. Despite the deleterious effects of hyperuricemia on endothelial function, the effect of UA on myocardial ischemia has not been previously studied. We aimed to investigate the relationship between UA and myocardial ischemia that was identified using dobutamine stress echocardiography (DSE). In this retrospective study, the laboratory and DSE reports of 548 patients were reviewed. The patients were divided into two groups based on the presence of ischemia and further subdivided into three groups according to the extent of ischemia (none, ischemia in 1-3 segments, ischemia in > 3 segments). Serum UA levels were compared. Determinants of ischemia were assessed using a regression model. UA was increased in patients with ischemia and was correlated with the number of ischemic segments (p < 0.001). A cutoff value of UA > 5 mg/dl had 63.9 % sensitivity, 62.0 % specificity, 42.5 % positive predictive value (PPV), and 79.6 % negative predictive value for ischemia. When the positive DSE exams were further sorted according to the UA cutoff, the PPV of DSE increased from 80.2 to 94.0 %. Uric acid (odds ratio 1.51; 95 % CI 1.14-1.99), diabetes mellitus, HDL and glomerular filtration rate were found to be independent determinants of myocardial ischemia in DSE. Increased UA is associated with both the presence and extent of DSE-identified myocardial ischemia. A UA cutoff may be a good method to improve the PPV of DSE.Öğe Relation of 24-Hour Urinary Aldosterone Levels with Nondipper Blood Pressure Pattern in Normotensive Individuals(Elsevier Science Inc, 2013) Soylu, Ahmet; Alibasic, Hayrudin; Yildirim, Elif; Toker, Aysun; Erdogan, Halil Ibrahim; Duzenli, Mehmet Akif; Tokac, Mehmet[Abstract Not Availabe]Öğe The Relationship among Thiazide Like Diuretic, Uric Acid and Erectile Dysfunction in Hypertensive Subjects(Elsevier Science Inc, 2013) Aribas, Alpay; Kayrak, Mehmet; Ulucan, Seref; Keser, Ahmet; Demir, Kenan; Alibasic, Hayrudin; Akilli, Hakan[Abstract Not Availabe]Öğe The relationship between serum asymmetric dimethylarginine levels and subjective sleep quality in normotensive patients with type 2 diabetes mellitus(Korean Assoc Internal Medicine, 2015) Aribas, Alpay; Kayrak, Mehmet; Tekinalp, Mehmet; Akilli, Hakan; Alibasic, Hayrudin; Yildirim, Serkan; Gunduz, MehmetBackground/Aims: Poor sleep quality (SQ) is associated with increased cardiovascular mortality and morbidity. Additionally, asymmetric dimethylarginine (ADMA) is an independent predictor of cardiovascular mortality and morbidity. However, no sufficient data regarding the relationship between ADMA levels and SQ have been reported. The goal of the current study was to evaluate the association between SQ and ADMA levels in normotensive patients with type 2 diabetes mellitus. Methods: The study participants consisted of 78 normotensive type 2 diabetics. The SQ of all participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). Patients with a global PSQI score > 5 were defined as poor sleepers. Factors associated with poor SQ were analyzed using a multiple regression model. Serum ADMA levels were measured using high performance liquid chromatography. Results: The median ADMA levels of the poor sleepers were increased compared with patients defined as good sleepers (5.5 [4.2 to 6.6] vs. 4.4 [2.9 to 5.4], p < 0.01, respectively). However, the L-arginine/ADMA ratio was decreased in poor sleepers (p < 0.01). Global PSQI scores were positively correlated with ADMA levels (p < 0.01) and negatively correlated with the L-arginine/ADMA ratio (p = 0.02). ADMA levels were correlated with sleep latency (p < 0.01) and sleep efficiency (p = 0.01). Logistic regression analysis showed that ADMA levels (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.16 to 2.44; p = 0.01) and body mass index (OR, 1.15; 95% CI, 1.01 to 1.31; p = 0.04) were associated with poor SQ independently of glomerular filtration rate, sex, age, duration of diabetes, hemoglobin A1c, total cholesterol, and systolic blood pressure. Conclusions: Self-reported SQ was independently associated with ADMA levels in normotensive patients with diabetes mellitus.Öğe The relationship between uric acid and erectile dysfunction in hypertensive subjects(Taylor & Francis Ltd, 2014) Aribas, Alpay; Kayrak, Mehmet; Ulucan, Seref; Keser, Ahmet; Demir, Kenan; Alibasic, Hayrudin; Akilli, HakanBackground. Endothelial dysfunction plays a major role in erectile dysfunction (ED). Uric acid (UA) is a marker of endothelial dysfunction. We hypothesized that increased UA levels may be associated with ED and aimed to investigate whether there is a relationship between, UA and ED in hypertensive patients. Methods. A total of 200 hypertensive patients who have a normal treadmill exercise test were divided into two groups based on the Sexual Health Inventory for Men (SHIM) test (<21 defi ned as ED n = 110, and >= 21 defi ned as normal erectile function n = 90). The differences between the ED and normal erectile function groups were compared and determinants of ED were analyzed. Main results. The prevalence of ED was found to be 55.0%. Office blood pressure level was comparable between groups. UA levels were significantly increased in the ED group (6.20 +/- 1.56 vs 5.44 +/- 1.32, p = 0.01). In a regression model, age [odds ratio (95% confidence interval): 1.08 (1.04-1.14), p = 0.001], smoking [odds ratio: 2.33 (1.04-5.20), p = 0.04] and UA [odds ratio: 1.76 (1.28-2.41), p = 0.04] were independent determinants of ED. An UA level of >5.2 mg/dl had 76.2% sensitivity, 43.7% specificity, 62.9% positive and 59.4% negative predictive value for determining ED. Conclusion. UA is an independent determinant of ED irrespective of blood pressure control and questioning erectile function for hypertensive patients with increased UA levels may be recommended.
