Publication Open Access Effect of transfusion of washed red blood cells on serum potassium level in hemodialysis patients(2017-01-01) DEMIRTUNC, Refik; OZENSOY, Ugur; CETINKAYA, Fuat; KAYATAS, Kadir; USTUN, Emel; Kazancioglu, RÜMEYZA; KARATOPRAK, CUMALİ; KARATOPRAK, CUMALİ; KAZANCIOĞLU, RÜMEYZABackground/aim: This study aimed to compare washed red blood cell (WRBC) transfusion versus nonwashed RBC (NWRBC) transfusion in terms of posttransfusion potassium levels in dialysis patients on a day when the patient did not receive dialysis. Materials and methods: The patients were randomly assigned into two groups, i.e. those receiving WRBCs (n = 21) and those receiving NWRBCs (n = 17). Both groups received one unit of RBCs. Serum potassium and sodium levels were measured before and at the 1st, 2nd, 3rd, 4th, and 6th hours after transfusion. Results: In the WRBC group, the changes in the serum potassium levels at the 3rd, 4th, and 6th hours after transfusion were significant compared with pretransfusion levels. In the serum potassium levels mean decreases by 0.38 ± 0.57 mEq/L at the 3rd hour (P = 0.006), by 0.32 ± 0.47 mEq/L at the 4th hour (P = 0.005), and by 0.32 ± 0.51 mEq/L at the 6th hour (P = 0.009) after transfusion were significant compared with the pretransfusion levels. Conclusion: Although nonwashed RBC transfusion does not change serum potassium levels, washed RBC transfusion significantly reduces serum potassium levels. Washed RBC transfusion is considered to be safer in hemodialysis patients with hyperkalemia and anemia.Publication Open Access International Society of Nephrology Global Kidney Health Atlas: structures, organization, and services for the management of kidney failure in Eastern and Central Europe(2021-05-01T00:00:00Z) Dębska-Ślizień, Alicja; Bello, Aminu K.; Johnson, David W.; Jha, Vivekanand; Harris, David C.H.; Levin, Adeera; Tonelli, Marcello; Saad, Syed; Zaidi, Deenaz; Osman, Mohamed A.; Ye, Feng; Khan, Maryam; Lunney, Meaghan; Okpechi, Ikechi G.; Turan Kazancioglu, Rümeyza; KAZANCIOĞLU, RÜMEYZAProvision of adequate kidney care for patients with chronic kidney disease or kidney failure (KF) is costly and requires extensive resources. There is an inequality in the global distribution of wealth and resources needed to provide this care. In this second iteration of the International Society of Nephrology Global Kidney Health Atlas, we present data for countries in Eastern and Central Europe. In the region, the median prevalence of chronic kidney disease was 13.15% and treated KF was 764 per million population, respectively, slightly higher than the global median of 759 per million population. In most countries in the region, over 90% of dialysis patients were on hemodialysis and patients with a functioning graft represented less than one-third of total patients with treated KF. The median annual costs for maintenance hemodialysis were close to the global median, and public funding provided nearly universal coverage of the costs of kidney replacement therapy. Nephrologists were primarily responsible for KF care. All countries had the capacity to provide long-term hemodialysis, and 95% had the capacity to provide peritoneal dialysis. Home hemodialysis was generally not available. Kidney transplantation and conservative care were available across most of the region. Almost all countries had official dialysis and transplantation registries. Eastern and Central Europe is a region with a high burden of chronic kidney disease and variable capacity to deal with it. Insufficient funding and workforce shortages coupled with increasing comorbidities among aging patients and underutilization of cost-effective dialysis therapies such as peritoneal dialysis and kidney transplantation may compromise the quality of care for patients with KF. Some workforce shortages could be addressed by improving the organization of nephrological care in some countries of the region.Publication Open Access Comparative Evaluation of Orthostatic Hypotension in Patients with Diabetic Nephropathy.(2021-07-20T00:00:00Z) Aytaş, Gamze; Elçioğlu, Ömer C; Kazancıoğlu, Rümeyza; Gürsu, Meltem; Artan, A Serra; Yabacı, Ayşegül; Soysal, PINAR; Bilgi, Kadir; Özçelik, Semra; KAZANCIOĞLU, RÜMEYZA; ELÇİOĞLU, ÖMER CELAL; GÜRSU, MELTEM; YABACI TAK, AYŞEGÜL; SOYSAL, PINAR; ÖZÇELİK, SEMRAIntroduction: Orthostatic hypotension (OH) affects 5-20% of the population. Our study investigates the presence of OH in diabetic nephropathy (DNP) patients and the factors affecting OH in comparison with nondiabetic chronic kidney disease (NDCKD) patients. Method: Patients presented to the nephrology clinic, and those who consented were included in the study. DNP was defined by kidney biopsy and/or clinical criteria. NDCKD patients of the same sex, age, and eGFR were matched to DNP patients. Demographic parameters and medications were obtained from the records. OH was determined by Mayo clinic criteria. The same researcher used an electronic device to measure blood pressure (BP). All samples were taken and analyzed the same day for biochemical and hematologic parameters and albuminuria. Results: 112 (51 F, 61 M, mean age: 62.56 ± 9.35 years) DNP and 94 (40 F, 54 M, mean age: 62.23 ± 10.08 years) NDCKD patients were included. There was no significant difference between DNP and NDCKD groups in terms of OH prevalence (70.5 vs. 61.7%, p = 0.181). Male patients had significantly higher OH prevalence than female patients (74.7 vs. 60.0%, p = 0.026). There was no significant difference in change in systolic BP between the groups (24.00 [10.00-32.00] mm Hg vs. 24.00 [13.75-30.25] mm Hg, p = 0.797), but the change in diastolic BP was significantly higher in the DNP group (8.00 [2.00-13.00] mm Hg vs. 6.00 [2.00-9.00] mm Hg, p = 0.025). In the DNP group, patients with OH had significantly higher uric acid levels than those without OH (7.18 ± 1.55 vs. 6.36 ± 1.65 mg/dL, p = 0.017). And, 73.7% of patients on calcium channel blockers developed OH (p = 0.015), and OH developed in 80.6% of 36 patients on alpha-blockers (p = 0.049). Conclusion: OH prevalence is very high in CKD, and etiology of CKD does not have a statistically significant effect on the frequency of OH, despite a difference that could be meaningful clinically. Therefore, patients with CKD are checked for OH, with or without concurrent diabetes mellitus. Evaluation of postural BP changes should be a part of nephrology practice.Publication Metadata only Düzenli Hemodiyaliz Tedavisi Alan Hastalarda Vücut Kitle İndeksinin Laboratuvar Parametreleri ile İlişkisi.(2017-10-15T00:00:00Z) SAYAN, CANAN; BÜLBÜL, ELİF; PEÇEN, MUSTAFA; GÜL, ELİF BUSE; DELİGÖZ BİLDACI, YELDA; ELÇİOĞLU, ÖMER CELAL; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA; ELÇİOĞLU, ÖMER CELAL; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZAPublication Metadata only Mega Mesane; Batında Kitle Nedenlerinden Nadir Bir Olgu.(2017-10-10T00:00:00Z) DELİGÖZ BİLDACI, YELDA; ELÇİOĞLU, ÖMER CELAL; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA; ELÇİOĞLU, ÖMER CELAL; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZAPublication Metadata only Hayat kurtaran tercih: periton diyalizi.(2015-10-25T00:00:00Z) Yücel, L,; Sayan, C,; KAZANCIOĞLU, RÜMEYZA; Erkoç, R,; Döner, B,; Deligöz Bildacı, Y,; KAZANCIOĞLU, RÜMEYZAPublication Metadata only Tuberculosis in peritoneal dialysis patients in an endemic region.(2011-01-01T00:00:00Z) Gursu, MELTEM; TAYFUR, F; BESLER, M; KAPTANOGULLARI, O; KUCUK, M; AYDIN, Z; BASTURK, T; UZUN, S; KARADAG, S; TATLI, E; SUMNU, A; OZTURK, S; KAZANCIOGLU, RÜMEYZA; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZAPublication Metadata only Otozomal Dominant Polikistik Böbrek Hastalığında Total Oksidan/Antioksidan Seviyelerin Böbrek Fonksiyonlarıyla İlişkisi(2021-10-13T00:00:00Z) Aris, Özlem; Büyükaydın, Banu; Artan, Ayşe Serra; Mirioğlu, Şafak; Gürsu, Meltem; Kazancıoğlu, Rümeyza; Elçioğlu, Ömer Celal; MİRİOĞLU, ŞAFAK; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA; ELÇİOĞLU, ÖMER CELALPublication Metadata only Periton Diyalizi Başvuru Kitabı(2013-01-01T00:00:00Z) KAZANCIOĞLU, RÜMEYZA; KAZANCIOĞLU, RÜMEYZAPublication Metadata only Paroxysmal nocturnal hemoglobinuria and acute kidney injury: A case report(2013-02-01) SUMNU, ABDULLAH; DÖNMEZ, HALIL; GÜRSU, MELTEM; CEBECI, EGEMEN; OZTURK, SAVAS; KILIÇARSLAN, IŞIN; KAZANCIOĞLU, RÜMEYZA; KAZANCIOĞLU, RÜMEYZA
