3. | Daptomycin in left-sided endocarditis: A single center experience Burak Açar, Yasemin Tezer Tekçe, Çağrı Yayla, Sefa Ünal, Ahmet Göktuğ Ertem, Bihter Şentürk, Sinan Aydoğdu PMID: 28595200 doi: 10.5543/tkda.2017.60784 Pages 310 - 315 Objective: Infective endocarditis (IE) carries a high risk of cardiac morbidity and mortality, despite advances in the contemporary armamentarium. Along with the development of antibiotic resistant strains, research focusing on the efficacy of novel agents other than standard antibiotic regimens continues. Daptomycin, one of these antibiotics, is approved for the treatment of Staphylococcus bacteremia and right-sided endocarditis. This retrospective study was an investigation of the effectiveness of daptomycin in patients with left-sided IE. Methods: Fourteen patients (mean age 50.9±16.5; range 24 to 70 years) with the diagnosis of left-sided IE based on modified Duke criteria received daptomycin as monotherapy. Outcome was evaluated according to clinical improvement, microbiological eradication, and in-hospital mortality. Results: Blood culture was positive in 13 patients (92.8%) and staphylococci were isolated in all but 1 patient (92.3%). Daptomycin was administered as monotherapy at a dose of 6 or 8 mg/kg/day for mean of 40.6±4.4 days. Clinical recovery rate was 71.4% and microbiological eradication rate was 85.7%. Mean duration of clinical recovery was 8.7±3.2 days and duration of microbiological eradication was 11.1±3.6 days. Side effects developed in 6 patients, but drug discontinuation was not required in any patient. Ten patients improved without complications. Two patients were lost due to heart failure and multiple-organ failure while treatment was continuing, and 2 patients died in early cardiac postoperative period. Conclusion: Daptomycin is an effective and safe alternative to standard antibiotic therapy for the treatment of left-sided IE. |
4. | As cardioprotective and angiogenic biomarker, can ghrelin predict coronary collateral development and severity of coronary atherosclerosis? Mehmet Kadri Akboğa, Gülten Taçoy, Canan Yılmaz Demirtaş, Sedat Türkoğlu, Bülent Boyacı, Atiye Çengel PMID: 28595201 doi: 10.5543/tkda.2017.96169 Pages 316 - 323 Objective: Ghrelin exerts protective effects on cardiovascular system by inhibiting progression of atherosclerosis, supression of vascular inflammation, and stimulating angiogenesis. Thus, the aim of this study was to investigate the effect of serum ghrelin on coronary collateral development and SYNTAX score in patients with severe coronary artery disease. Methods: Total of 91 patients who had ≥90% stenosis in at least one major coronary artery were prospectively included in this cross-sectional, observational study. Collateral degree was graded according to Rentrop-Cohen classification. Patients with grade 2 or 3 collateral degree were allocated to Good Collateral Group and patients with grade 0 or 1 collateral degree were included in Poor Collateral Group. Ghrelin and vascular endothelial growth factor A (VEGF-A) levels were measured using radioimmunoassay and ELISA kits. Results: Serum ghrelin and VEGF-A levels were significantly higher in Good Collateral Group. Furthermore, ghrelin level showed significant inverse correlation with SYNTAX score (r=-0.348; p=0.001). In multivariable regression analysis, ghrelin (Odds ratio, 1.013; 95% confidence interval, 1.011–1.017; p=0.013), VEGF-A, fasting plasma glucose and presence of chronic total occlusion were independent predictors of good collateral development. In receiver operating characteristic curve analysis, ghrelin value cut-off point of ≥781 pg/mL predicted good collateral development with sensitivity of 73.1% and specificity of 67.7%. Conclusion: Findings suggested that ghrelin has antioxidant and antiinflammatory properties that protect endothelial functions and also stimulate angiogenesis, which results in development of good coronary collateral and inhibition of progression of coronary atherosclerosis. |
5. | Vitamin D is a predictor of ST segment resolution and infarct size following thrombolysis in patients with acute ST elevation myocardial infarction Ahmad Separham, Bahram Sohrabi, Leili Pourafkari, Nazli Sepasi, Samad Ghaffari, Naser Aslanabadi, Nader D Nader PMID: 28595202 doi: 10.5543/tkda.2017.17737 Pages 324 - 332 Objective: Vitamin D (VitD) insufficiency is linked to various chronic conditions, including cardiovascular disease. Aim of the present study was to examine role of serum VitD in resolution of ST segment elevation (STR) in response to thrombolytic therapy following acute ST elevation myocardial infarction (STEMI). Methods: VitD was measured prospectively in all consecutive patients who were admitted with STEMI and received thrombolysis during the calendar year of 2014. STR was defined as ≥50% decrease in initial magnitude of STR 90 minutes after treatment. Multivariate binary logistic regression analysis was performed to identify effect of confounding variables on STR. Results: Average age was 58±14 years in 227 patients (41 female and 186 male). Total of 24.7% of patients had sufficient VitD (>30 ng/mL), whereas 46.2% had VitD insufficiency (10–30 ng/mL), and remaining 29.1% had VitD deficiency (<10 ng/mL). Significant STR occurred in 57.3% of the patients. In a nonlinear pattern, serum VitD concentration directly correlated with likelihood of STR (p=0.012). VitD deficient patients had larger enzymatic infarct size compared with those with sufficient VitD (p=0.026). In multivariate logistic regression analysis, while diabetes doubled (p=0.033) and involvement of anterior wall created 2.7-fold increase in probability of non-resolution (p=0.001), for every unit increase in serum VitD, likelihood of STR increased by 2.1% (p=0.023). Conclusion: VitD deficiency in patients with STEMI was associated with lower occurrence of STR and larger enzymatic infarct size in response to thrombolytic therapy. |
6. | Parameters of ventricular repolarization in patients with autoimmune hepatitis Burak Açar, Mahmut Yüksel, Çağrı Yayla, Özgür Kırbaş, Sefa Ünal, Ahmet Göktuğ Ertem, Koray Demirtaş, Mustafa Kaplan, Meral Akdoğan, Sabite Kaçar, Ertuğrul Kayaçetin, Sinan Aydoğdu PMID: 28595203 doi: 10.5543/tkda.2017.57870 Pages 333 - 338 Objective: Autoimmune hepatitis (AIH) is a liver disorder that affects both children and adults. It is characterized by inflammatory liver histology, elevated transaminase level, circulating nonorgan-specific autoantibodies, and increased level of immunoglobulin G in the absence of known etiology. Ventricular repolarization has been evaluated using T wave and QT interval measurements in patients with hepatic cirrhosis. Ventricular repolarization may be defined using QT interval, QT dispersion, and T wave measurements. Recently, it has been demonstrated that peak and end of the T wave (Tp-e) interval, Tp-e/QT, and Tp-e/corrected QT interval (QTc) ratios can be novel indicators for prediction of ventricular arrhythmias and mortality. In this study, an investigation of ventricular repolarization using Tp-e interval and Tp-e/QT ratio in patients with AIH was performed. Methods: Total of 31 patients with AIH and 31 controls were enrolled in the present study. Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were measured on 12-lead electrocardiogram. Results: QT interval (378.9±41.4 vs. 350.0±22.7; p=0.001), QTc interval (396.8±46.7 vs. 367.3±34.9; p=0.039), Tp-e interval (68.2±12.3 vs. 42.5±6.8; p<0.001), Tp-e/QT ratio (0.18±0.02 vs. 0.12±0.01; p<0.001) and Tp-e/QTc ratio (0.17±0.02 vs. 0.11±0.01; p<0.001) were significantly higher in patients with AIH than control patients. Conclusion: The results of the present study indicated that Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were greater in patients with AIH. |
7. | Association of neutrophil/lymphocyte ratio and CHA2DS2-VASc score with left atrial thrombus in patients who are candidates for percutaneous mitral balloon valvuloplasty Orhan Maden, Kevser G Balci, Mustafa M Balci, Serdar Kuyumcu, Hatice Selçuk, Mehmet T Selçuk PMID: 28595204 doi: 10.5543/tkda.2017.50475 Pages 339 - 347 Objective: Association between inflammation and pro-thrombotic state has been described previously. Aim of the present study was to investigate if presence of left atrial (LA) thrombus or spontaneous echocardiographic contrast (SEC) in rheumatic mitral stenosis (MS) was related to neutrophil/lymphocyte ratio (NLR), and to determine predictive utility of the CHA2DS2-VASc risk stratification score in patients with mitral stenosis complicated by LA thrombus. Methods: NLR and CHA2DS2-VASc score of 188 patients with MS and 35 healthy controls were evaluated. All analyses were also conducted according to rhythm status, excluding control group. Results: Among patients with MS, there were 31 patients in thrombus-positive group, 142 patients in SEC-positive group, and 15 patients in thrombus/SEC-negative group. Among patients with MS and sinus rhythm (SR) (n=105; 55.8%); 9.5% of them had LA thrombus, and 78% of them had SEC. In the SR group, median NLR was significantly higher in thrombus-positive group compared with thrombus/SEC-negative and control groups (p<0.001). Among patients with MS and atrial fibrillation (AF); there was no significant difference regarding NLR according to thrombus and SEC presence (p=0.214). In both SR and AF groups, there was no significant difference according to SEC/thrombus presence regarding median CHA2DS2-VASc score (p>0.05). Conclusion: Elevated NLR is related to presence of LA thrombus in patients with MS and SR. The utility of CHA2DS2-VASc score in patients with MS and SR complicated by LA thrombus is debatable, according to our results. |
8. | The relationship between serum lipid parameters and renal frame count in hypertensive patients with normal renal functions Emrah Ipek, Mustafa Yolcu, Erkan Yıldırım PMID: 28595205 doi: 10.5543/tkda.2017.05248 Pages 348 - 354 Objective: Atherosclerosis can contribute to renovascular disease, and high cholesterol level is an independent risk factor for disease progression. Renal frame count (RFC) is an objective angiographic method of measuring macrovascular blood flow in the main renal artery and its segmental branches. The aim of the present study was to demonstrate relationship between serum lipid parameters and RFC. Methods: In this cross-sectional study, 116 hypertensive patients were allocated into 2 groups according to serum low-density lipoprotein (LDL) levels. Group 1 comprised 60 patients with LDL <130 mg/dL and Group 2 consisted of 56 individuals with LDL ≥130 mg/dL. The patients were also divided into 2 groups according to total cholesterol (TC) levels (52 patients in group with TC <200 mg/dL and 64 patients in group with TC ≥200 mg/dL). Results: Group 2 had higher mean RFC than Group 1 (p<0.001). RFC of both kidneys in Group 2 was significantly higher than results in Group 1 (p<0.001 and p=0.023, respectively). We found similar significant results in comparison of TC-based patient groups. RFC had positive correlation with smoking, TC, and LDL (r=0.326, p=0.035; r=0.393, p=0.010; and r=0.386, p=0.012, respectively). In multivariate linear regression analysis, LDL, TC, smoking, and creatinine clearance were independent predictors of RFC. Conclusion: In conclusion, in hypertensive patients with normal renal function, LDL, TC, and smoking may be predictors of RFC and aggressive risk factor modification may help to reduce the risk of renal failure. |

14. | Closure of wide patent ductus arteriosus using a fenestrated muscular VSD occluder device in a pediatric patient with Down syndrome and pulmonary hypertension Osman Güvenç, Murat Saygı, İbrahim Halil Demir, Ender Ödemiş PMID: 28595211 doi: 10.5543/tkda.2016.38283 Pages 373 - 376 Patients with wide patent ductus arteriosus and significant pulmonary hypertension not treated in time constitute a significant problem for cardiologists. For these patients, tests that could aid in decision-making for further planning include reversibility and balloon occlusion tests performed in the catheterization laboratory. Devices developed for the closure of ductus as well as different devices with off-label use may be employed in patients scheduled for transcatheter occlusion. When result of reversibility test is borderline positive, the use of fenestrated device may be applicable for selected patients. Presently described is case of a 10-year-old patient with Down syndrome who had a wide ductus and systemic pulmonary hypertension. Transcatheter closure procedure was performed with off-label use of a fenestrated muscular ventricular septal defect occluder device. |
