Article Aortic Dissection in Case With Chronic Kidney Disease(Aves, 2017) Buyukaydin, Banu; Alay, Murat; Kazancioglu, Rumeyza; Ugur, Aycan; Tunc, Muhammed; Teker, Melike Elif; Erkoc, RehaAortic disection is an urgent clinical problem that rapid diagnosis and appropriate treatment is life-saving. Hypertension is one of the major risk factors. In this paper, a 56 years old female patient with hypertension and renal failure was presented. In this case after clinical suspicion aortic dissection was diagnosed with imaging studies. Endovascular aortic repair was performed but after surgery, patient died because of possible hemorrhage complication. In aortic disection, diagnosis and treatment could be fast. In chronic kidney disease the prognosis of these patients is adversely affected. Despite proper surgical intervention accompanying medical problems like chronic kidney disease have negative effects on survival.Article Are Serum Lipid Levels Associated With Depression in Hemodialysis Patients(Turk Nefroloji Diyaliz Transplantasyon dergisi, 2006) Sahin, Idris; Kiran, Umit Kemal; Sahin, Huseyin Avni; Ustun, Yusuf; Agargun, Mehmet Yucel; Erkoc, RehaBackground: Recent study suggested a relation between low levels of serum lipids and depression. The aim of this study was to assess the association between serum lipid levels and depression in patients with end-stage renal disease (ESRD). Methods: All the patients who were attending Yuzuncu Yil University Faculty of Medicine Training Hospital Hemodialysis Unit, in Turkey, from August 2000 to July 2001, were prospectively studied. Serum TC, LDL-c, HDL-c, VLDL-c and triglyceride levels were measured and Beck Depression Inventory (BDI) was administered to all patients. Diabetic patients were excluded. Results: There were 46 patients (25 males and 21 females). Mean duration of hemodialysis was 28.1 +/- 30.2 months. Mean Kt/V was 1.2 +/- 0.4. The mean age of study group was 45.2 +/- 16.3 years and the age range was 15-73 years. Mean serum albumin concentration was 3.63 +/- 0.55 (2.5-4.7) g/dL. The patients' mean BDI was 15.9 +/- 6.2 (431). There was association between serum TC (total cholesterol), LDL-c (low density lipoprotein cholesterol), HDL-c (high density lipoprotein cholesterol) and depression but no association between serum VLDL-c (very-low density lipoprotein cholesterol) and triglyceride levels and depression in patients with ESRD. Conclusion: Depression is the most common psychological finding in patients with ESRD. Our study demonstrate that there were associations between low serum TC, LDL-c, HDL-c levels and depression but there was no association between depression and serum triglyceride and VLDL-c levels in patients with ESRD.Article Assessment of Internal Jugular Vein Thrombosis Due To Central Venous Catheter in Hemodialysis Patients: a Retrospective and Prospective Serial Evaluation With Ultrasonography(Sage Publications inc, 2012) Yardim, Hasan; Erkoc, Reha; Soyoral, Yasemin Usul; Begenik, Huseyin; Avcu, SerhatAim: We aimed to evaluate the frequency of catheter-related internal jugular vein (IJV) thrombosis, associated factors, and the anatomical variations of IJV in hemodialysis patients. Material and methods: Hemodialysis patients were evaluated with B-mode ultrasonography (USG). Participants in the prospective group were evaluated using USG prior to catheter insertion, 10 days after catheter insertion, at the time of catheter removal, and 15 days after removal. Results: The rate of thrombosis was increased correlated with the number of catheter insertions. These rates were 14%, 15%, and 47% in those undergoing catheter insertion once, twice, and three times, respectively (P < .05). The anatomical variations of IJV were 21% in the retrospective cases. No significant relationship was found between anatomical variations and thrombosis and between some biochemical parameters and thrombosis. Conclusion: Catheter-related IJV thrombosis is frequent in hemodialysis patients. Long catheter remaining time and repeated catheterization increase the thrombosis rate.Article The Assessment of the Diet Knowledge Level and Daily Dietary Practice of the Relatives of Hemodialysis Patients(Drunpp-sarajevo, 2012) Emre, Habib; Soyoral, Yasemin Usul; Begenik, Huseyin; Erdur, Mehmet Fatih; Kucukoglu, Mehmet Emin; Erkoc, RehaObjectives: In this study, we aimed to investigate the level of nutrition and diet knowledge and the daily dietary practices of the relatives of hemodialysis patients. Material and Methods: We recruited 39 relatives whose patients receiving hemodialysis, and who provided the patient's dietary needs. The questionnaire containing questions regarding daily salt, water, potassium and phosphate intakes was conducted to the patient's relatives. The questionnaire results were reflected to the graphics with numbers and percentages. Results: The patient's relatives had sufficient information about the salt and water intakes, but they were not very sensitive to use their dietary knowledge during their daily practice. The relatives did not have enough information about the foods which containing phosphate and potassium and the clinical situations/complications related to the phosphor and potassium. Conclusions: The nutrition and diet education should be also provided to the patients' relatives. Besides the education, the patients and the relatives should be followed up periodically to see if they apply their knowledge. The relatives especially should be instructed about foods containing salt, phosphate and potassium.Article Azigos Vein: Is It a Malposition or an Alternative(Turk Nefroloji Diyaliz Transplantasyon dergisi, 2011) Emre, Habib; Soyoral, Yasemin Usul; Begenik, Huseyin; Demirkiran, Davut; Erdur, Fatih Mehmet; Gumrukcuoglu, Hasan Ali; Erkoc, RehaUse of a temporary central venous catheter is common practice in hemodialysis therapy. One of the most common complications of central venous catheterization is catheter malposition. Cannulation of the azygos vein (particularly the azygos arch) is a rare but hazardous catheter malposition that carries a substantial risk of perforation, thrombosis and vascular stenosis. On the other hand, the azygos vein can be used for vascular access in patients whose superior vena cava and inferior vena cava are thrombosed. We present a case where the required blood flow for hemodialysis was provided by a dilated azygos vein due to superior vena cava obstruction.Letter Burkitt Lymphoma in Renal Transplant Recipient(Taylor & Francis inc, 2007) Soyoral, Yasemin; Dogan, Ekrem; Sayarfloglu, Hayriye; Erkoc, Reha; Begenik, HuseyinLetter Cloudy Dialysate Due To Lercanidipine(Oxford Univ Press, 2006) Topal, Cevat; Sayarlioglu, Hayriye; Dogan, Ekrem; Erkoc, Reha; Soyoral, YaseminArticle Comparative Effects of Carvedilol and Lercanidipine on Ultrafiltration and Solute Transport in Capd Patients(Taylor & Francis Ltd, 2009) Topal, Cevat; Erkoc, Reha; Sayarlioglu, Hayriye; Dogan, Ekrem; Beyenik, HuseyinBackground. Peritonitis, the type of buffer used in the dialysate, continue ambulatory peritoneal dialysis (CAPD) of greater than two years duration, increased exposure to dialysate glucose, diabetes mellitus, and the use of beta blockers may contribute to impaired ultrafiltration. Objectives. The aim of the present study is to compare the effects of a calcium-channel blocker and a beta-blocker on the peritoneal transport and clearance. Methods. We studied 48 patients with ESRD on chronic peritoneal dialysis, included 27 females and 19 males with mean age 42.6 +/- 16.4 years. Two patients were excluded from the study due to peritonitis. Patients were treated either with carvedilol or lercanidipine. In all patients; peritoneal equilibration test ( PET), ultrafiltration (UF), Kt/V ratio, creatinine clearance (CrCl), systolic blood pressure, diastolic blood pressure, serum BUN, creatinine, glucose, sodium, potassium, albumin, cholesterol, and triglyceride values were obtained before and after 8 weeks from the start of the drug treatment. Results. Lercanidipine and carvedilol showed a good antihypertensive effect in CAPD patients. Both drugs had a good tolerability profile and showed no effect on plasma lipids. There were no differences in terms of PET, ultrafiltration, Kt/V ratio, CrCl, systolic blood pressure, diastolic blood pressure, serum BUN, creatinine, glucose, sodium, and potassium values between both patient groups. After antihypertensive treatment, neither group showed a difference in the above-mentioned parameters (p > 0.05) except potassium, which was significantly higher in the carvedilol group (p < 0.05). Conclusions. In CAPD patients. short-term usage of carvedilol has no effect on ultrafiltration and solute transport like lercanidipine. Both drugs showed a good antihypertensive effect.Article Comparison of the Automated Cell Counter and Manual Method for the Assessment of Dialysis Fluids in Peritoneal Dialysis Patients(Drunpp-sarajevo, 2011) Soyoral, Yasemin Usul; Begenik, Huseyin; Aldemir, Mehmet Naci; Baran, Ali Irfan; Emre, Habib; Karahocagil, Mustafa Kasum; Erkoc, RehaObjective: To compare the accuracy of automated cell counter and the manual methods for the peritoneal fluid assessments in peritoneal dialysis patients. Material and Method: We analyzed 72 peritoneal fluid samples collected under sterile conditions from 27 patients with peritonitis (15 female; 12 male) following by the peritoneal dialysis unit of Yuzuncu Yil University Medical Faculty. The white blood cell counts of these peritoneal fluid samples were assessed by the both manual method and the automated cell counter. Results: The white blood cells were usually higher in the automated cell count method than the manual method (p<0,01). In 5 subjects, white cell counts were less than 100 cell/mu L in the manual method, but were more than 100 cell/mu L in the automated counter. There was a significant correlation between the manual and automated methods in terms of cell counts (p<0.01, r = 0.79). We also found good correlation between the two methods when WBC counts were greater than 300 cell/mu L (r = 0.87). Conclusions: There is a good correlation between the automated method and the manual methods for the assessment of peritoneal fluid samples in CAPD patients. However, in the assessment of fluids with less than 300 cell/mu L, the manual method should be preferred for critical clinical decisions.Article Correlation of 24-Hour Urine Sodium, Potassium and Calcium Measurements With Spot Urine(Modestum Ltd, 2013) Kara, Pinar Sonat; Erkoc, Reha; Soyoral, Yasemin Usul; Begenik, Huseyin; Aldemir, Mehmet NaciIn this study, we analyzed the correlation of sodium(Na), potassium(K) and calcium(Ca) amounts with spot urine(SU) and 24-hour urine(24-HU) collected as 8-hour portions. 21 hypertensive patients and 21 normotensive individuals were enrolled in the study. Na, K and Ca were studied in three sequential 8-hour urine samples and with the sum of three, 24-HU samples of the cases. Sodium/creatinine, potassium/creatinine, and calcium/creatinine were studied in fasting SU and serum Na, K and creatinine were studied. A significant correlation was found between the SU sodium/creatinine ratio and the Na amount in each 8-hour urine collections, and the Na amount in the 24-hour urine in hypertensive patients, the control group, and when all patients were evaluated together. When all group were evaluated together for Ca, a significant correlation was determined between the SU calcium/creatinine ratio and the Ca amount in all three 8-hour urine collections. The Na amount in the 24-HU may be estimated both with the SU Na/creatinine ratio and the 8-hour urine collection; SU does not have clinical significance for potassium. However, it may be estimated with 8-hour urine collections; SU may help roughly for calcium, and the collected urine gives higher correlation coefficients.Article The Course of Hypercalciuria and Related Markers of Bone Metabolism Parameters Associated With Corticosteroid Treatment(Taylor & Francis Ltd, 2012) Duzen, Omer; Erkoc, Reha; Begenik, Huseyin; Soyoral, Yasemin Usul; Aldemir, Mehmet NaciBackground and objective: Prolonged corticosteroid (CS) use induces osteoporosis; the pathogenesis of this condition is multifactorial and includes CS-induced hypercalciuria. We investigated the course of hypercalciuria and related markers of bone metabolism parameters during and after the CS treatment. Materials and Methods: We recruited 42 patients who were taking at least 10 mg/day of methylprednisolone or an equivalent dose of CSs for at least 30 days. The 24-h urinary calcium and sodium, a spot urinary calcium/creatinine ratio, and urinary deoxypyridinoline were measured prior to the treatment, at day 7, at days 30-60, and after the cessation of the treatment. Additionally, the serum levels of phosphorus, calcium, alkaline phosphatase (ALP), albumin, creatinine, osteocalcin, and parathyroid hormone (PTH) were analyzed. Results: The 24-h urinary calcium excretion was significantly increased at day 7 (182.2 +/- 158.6 mg/day; p < 0.001) and at days 30-60 (196.9 +/- 167.8 mg/day; p < 0.001) compared with baseline (98.7 +/- 88.1 mg/day) and returned to basal level after the cessation of the CSs (118.9 +/- 90.2 mg/day; p = 0.725). The urinary deoxypyridinoline level was significantly higher at days 30-60 compared with basal level. The serum osteocalcin level was decreased at days 30-60 when compared with day 7. No significant changes were detected in the PTH, phosphorus, creatinine, and ALP levels. Conclusions: CS treatment induces hypercalciuria just after starting the treatment until the end of it. CS-induced hypercalciuria promptly improved after cessation of the treatment. By days 30-60, the excretion of urinary deoxypyridinoline was accompanied by hypercalciuria. The serum osteocalcin level was decreased at days 30-60 when compared with day 7.Article Dialysis Therapy for Lactic Acidosis Caused by Metformin Intoxication: Presentation of Two Cases(Sage Publications Ltd, 2011) Soyoral, Yasemin Usul; Begenik, Huseyin; Emre, Habib; Aytemiz, Enver; Ozturk, Mustafa; Erkoc, RehaMetformin is an oral antidiabetic, which is frequently used in the treatment of type II diabetes mellitus. Serious side effects may be seen during the administration of high doses of metformin. Two cases of lactic acidosis due to ingestion of high dose metformin for suicidal purposes have been presented here; in both cases, clinical improvement was seen with bicarbonate hemodialysis.Article Diurnal Rhythm of Urinary Calcium Excretion in Adults(Taylor & Francis inc, 2008) Topal, Cevat; Algun, Ekrem; Sayarlioglu, Hayriye; Erkoc, Reha; Soyoral, Yasemin; Dogan, Ekrem; Cekici, SalihaTwenty-four-hour urinary calcium excretion is normally the equivalent of daily calcium intake, and varies between 200-300 mg/dL with a calcium/creatinine ratio of 0.07-0.15. In this study, we aimed to investigate the diurnal rhythm of calcium excretion in healthy individual. Forty subjects (30 male, 10 female) were involved into the study. The spot urine samples were taken at 08: 00, 14: 00, and 22: 00 together with a 24-hour collection. Mean spot urinary calcium levels at 08: 00, 14: 00, and 22: 00 were 12.39 +/- 8.19, 12.97 +/- 8.37, and 16.95 +/- 10.39 mg/dL, with calcium/creatinine ratios of 0.104 +/- 5.261, 0.119 +/- 7.85, and 0.133 +/- 8.17, respectively. Twenty-four-hour urinary calcium excretion was 12.74 +/- 7.31 mg/dL with a calcium/creatinine ratio of 0.111 +/- 5.41. The values at 08: 00, 14: 00, and of 24-hour collection were statistically similar (p > 0.05), but the nighttime values were significantly elevated (p < 0.05). In conclusion, calcium excretion is increased at night, and urinary calcium measurements should be interpreted accordingly.Article Effect of Depot Oral Cholecalciferol Treatment on Secondary Hyperparathyroidism in Stage 3 and Stage 4 Chronic Kidney Diseases Patients(Taylor & Francis Ltd, 2008) Dogan, Ekrem; Erkoc, Reha; Sayarlioglu, Hayriye; Soyoral, Yasemin; Dulger, HalukBy the time patients require dialysis replacement therapy, nearly all chronic kidney diseases (CKD) patients are affected with uremic bone diseases. High-turnover osteodystrophy can be prevented; patients with CKD should be monitored for imbalances in calcidiol (25 OH vitamin D), calcium, and phosphate homeostasis. We aimed to determine the effect of a monthly oral 300,000 IU vitamin D-3 (cholecalciferol) supplementation on the uremic bone diseases (UBD) markers such as iPTH and alkaline phosphatase in CKD patients. Among a total of 70 patients under treatment in the nephrology unit, 40 predialysis CKD patients (mean age of 49 14, male/female 20/20) were included the study. The patients were randomly divided into two groups. Treatment group included 20 patients (mean age of 51 +/- 14, male/female 9/11), and the control group comprised 20 patients (mean age of 47 +/- 14, male/female 9/11). Treatment group patients were given a single dose of Devit3 ampoule (300,000 U cholecalciferol) per month orally way. Patients in the control group did not take any vitamin D for a month. The level of calcidiol was lower than normal range in two groups. After a month, treatment group patient's calcidiol increased statistically significant (6.8 +/- 3.5 to 17.8 +/- 21.4 ng/mL, p < 0.001). After a month, iPTH level decreased in the treatment group statistically significantly (368 +/- 274 to 279 +/- 179 pg/ml, p < 0.001). At the 30(th) day of the treatment, in 9/20 of the treatment group patients (45%), the iPTH value decreased at least 30% (p < 0.001). We suggest that oral depot cholecalciferol treatment causes a statistically significant decrease of serum iPTH level but does not cause a statistically significant change in Ca, P, ratio of CaxP, or urinary calcium creatinine rate in UBD predialysis CKD. This treatment can be used safely for the predialysis CKD patients, along with the cautious control of serum calcium and phosphor.Conference Object The Effect of Zofenopril on the Peritoneal Membrane in Capd Patients(Oxford Univ Press, 2006) Sayarlioglu, Hayriye; Dogan, Ekrem; Erkoc, Reha; Soyoral, Yasemin; Kara, Pinar; Baykal, Sanem; Guducuoglu, HuseyinConference Object Effects of Low Sodium Dialysate in Chronic Hemodialysis Patients With Hypertension(Oxford Univ Press, 2007) Esen, Ramazan; Erkoc, Reha; Sayarlioglu, Hayriye; Soyoral, Yasemin; Dogan, Ekrem; Sekeroglu, Ramazan; Begenik, HuseyinArticle Effects of Low Sodium Dialysate in Chronic Hemodialysis Patients: an Echocardiographic Study(Taylor & Francis Ltd, 2007) Sayarlioglu, Hayriye; Erkoc, Reha; Tuncer, Mustafa; Soyoral, Yasemin; Esen, Ramazan; Gumrukcuoglu, Hasan Ali; Sayarlioglu, MehmetBackground. Chronic kidney disease (CKD) and hemodialysis (HD) patients who cannot restrict sodium consumption in their diets sometimes develop significant saline excess and hypertension between dialyses. This study assessed the effect of relatively low sodium dialysate dialysis on changes of echocardiography in hemodialysis patients. Methods and Results. Eighteen patients with end stage renal failure on chronic HD were studied (8 females, 10 males) with a mean age 48.3 +/- 14.6 (24-70) years. The mean time on HD was 30.8 +/- 14.0 (12-60) months. Patients with hematocrit levels under 24% were excluded from the study. In all patients, echocardiography was performed thrice weekly before and after eight-week HD treatment with low sodium dialysate hemodialysis by the same operator (135 mEq/L for patients with sodium levels less than 137, 137 for patients with sodium levels over 137). Left atrium (LA) and left ventricle (LV) volumes and ejection fractions were measured, specifically: LV systolic diameter (LVSD), LV diastolic diameter (LVDD), interventricular septum (IVS), tricuspid regurgitation (TR), mitral regurgitation (MR), pulmonary artery pressure (PAP), and inferior vein cava diameter (IVCD). Results. In terms of echocardiographic parameters, LVSD, TR, PAP, and IVCD were statistically decreased after low-sodium dialysate treatments (p = 0.002, 0.04, 0.013, and 0.00, respectively). Predialysis systolic and diastolic blood pressure (BP), post-dialysis systolic blood pressure, and interdialytic weight gain was statistically decreased when compared to basal levels (p = 0.00, p = 0.011, p = 0.022, p = 0.001, respectively). Conclusion A reduction of the dialysate sodium concentration based on the predialysis sodium levels of the patients could reduce the systolic BP and decrease the volume load on the heart as assessed by echocardiography. Within this short period, postdialysis diastolic BP could not be lowered. The effect of this approach should be studied in broad and lengthy series.Article Epidemiology of Glomerulonephritis in the City of Van: Pathological Findings of 129 Cases(Turk Nefroloji Diyaliz Transplantasyon dergisi, 2005) Sayarlioglu, Hayriye; Erkoc, Reha; Topal, Cevat; Dogan, Ekrem; Ozen, Suleyman; Bayram, Irfan; Ugras, SerdarEpidemiologies of nephropathies differ in different geographical and developmental areas. In order to determine the region's adult nephropathy profile, consecutive renal biopsies performed between January 1997 and December 2003 were reviewed. There were 129 cases (M 63, F 66, mean age 32.2 +/- 15.6), of which 115 had adequate biopsies. Lupus nephritis formed the largest diagnostic entity (23.3%). When lupus cases are excluded, the most common form of glomerulonephritis is membranoproliferative form (27.6%). While high lupus nephritis incidence may be due to our routine biopsy protocol for these patients, relatively higher incidence of MPGN may represent higher prevalences of different infections in the region.Article Fenofibrate-Induced Rhabdomyolysis in a Patient With Chronic Renal Failure Due To Nephrotic Syndrome: a Rare Case Report(Pergamon-elsevier Science Ltd, 2012) Erdur, Fatih Mehmet; Soyoral, Yasemin Usul; Emre, Habib; Begenik, Huseyin; Canbaz, Esra Turan; Erkoc, RehaObjectives: Fenofibrate is a fibric acid derivative that is used alone or combination with statins in the treatment of hyperlipidemia. These drugs have potential risks, including rhabdomyolysis and acute renal failure. Despite reports of rhabdomyolysis with the use of fenofibrate alone or with statin-fibrate combinations, there have been no cases of rhabdomyolysis described when fenofibrate was used alone to treat patients with chronic renal failure owing to nephrotic syndrome. Design and methods: We report on a 26-year-old male who presented with fenofibrate-induced rhabdomyolysis with chronic renal failure due to nephrotic syndrome. Results: After the discontinuation of fenofibrate, the patient was treated with intravenous fluid replacement and urine alkalization. Subsequently, his clinical and biochemical findings improved. Conclusions: Before starting fenofibrate therapy, the causes of secondary hyperlipidemia, especially nephrotic syndrome, should be investigated. In the presence of chronic renal failure and hypoalbuminemia, the fenofibrate dose should be adjusted. Physicians should be aware of the potential toxicities of fenofibrate, and patients should be informed about its potential side effects. (C) 2011 The Canadian Society of Clinical Chemists.

Several factors may lead to rhabdomyolysis. Fenofibrate is a fibric acid derivative agent that is used in the treatment of hyperlipidaemia. Although several case reports of rhabdomyolysis have been reported due to the combination of statin and fenofibrate, fenofibrate alone rarely causes rhabdomyolysis. When administering fenofibrate in chronic renal failure, dose should be adjusted. Here, we report a case with fenofibrate-induced rhabdomyolysis in a patient with chronic renal failure.
