Publication Metadata only Hemodiyaliz ve Periton Diyalizi Tedavisi Alan Hastalarda Uzun Dönemde Gelişen Kognitif ve Fiziksel Bozukluklar.(2021-10-13) BARUTÇU ATAŞ, DİLEK; VELİOĞLU, ARZU; ARIKAN, İZZET HAKKI; AŞICIOĞLU, EBRU; Süleymanova G., BARUTÇU ATAŞ D., TUĞCU M., VELİOĞLU A., ARIKAN İ. H., AŞICIOĞLU E.Giriş: Diyaliz hastalarında uzun dönemde gelişen kognitif ve fiziksel fonksiyonlardaki gerileme yaşam kalitesinde bozulma ve artmış mortalite ile ilişkilidir. Bu çalışmada hemodiyaliz ve periton diyalizi tedavisi alan hastalarda kognitif ve fiziksel bozuklukları belirleyerek karşılaştırmayı hedefledik. Yöntemler: Çalışmamıza 20 periton diyalizi (PD) ve 24 hemodiyaliz (HD) hastası dahil edildi. Hastaların kognitif bozukluklarını değerlendirmek için MoCA (Montreal Kognitif Değerlendirme) ve MMSE (Mini Mental Durum Değerlendirme) testleri, fiziksel bozuklukları değerlendirmek için Lawton ve Brody EGYA(Enstrümental Günlük Yaşam Aktivitesi) ile Katz GYA (Günlük Yaşam Aktivitesi) testleri kullanılmıştır. Hastaların medikal özgeçmişi, kronik hastalıkları, diyalize başlama tarihleri sorgulandı. Laboratuvar verileri kaydedildi. Bulgular:HD tedavisi alan hastalar daha yaşlıydı (55.3±15.3 vs 48.2±10.1 yıl p=0.036). Grupların demografik ve laboratuvar verileri Tablo 1’de gösterilmiştir. PD hastalarının MoCA (21.9±6.0 vs 16.6±7.1, p=0,008).Lawton ve Brody EGYA (7.6±1.6 vs 6.4±2.4, p=0.025) ve Katz GYA(6.0±0.0 vs 5.5±1.0, p=0.018) skorları HD hastalarından yüksekti. Gruplarının kognitif ve fiziksel fonksiyonları Tablo 2’de karşılaştırılmıştır. Korelasyon analizinde yaş ile MoCA (r= -0.482, p= 0.001), MMSE (r= -0.462, p= 0.002) ve EGYA (r= -0.549, p= 0.001) arasında negatif korelasyon mevcuttu. Sonuç: Bu çalışmada her iki grupta da hastaların önemli bir kısmında kognitif ve fiziksel fonksiyonlarda bozulma mevcuttu. Ancak PD grubunda hastaların kognitif ve fiziksel fonksiyonlarının HD grubuna nazaran daha iyi korunduğunu gösterdik. İlerleyen dönemlerde diyaliz hastalarında gelişecek bu bozuklukların önlenmesi için hastaların yakından takip edilmesi gerekmektedir.Publication Metadata only Cardiac Risk Assessment in Kidney Transplant Candidates: Clinical Usefulness of Different Guidelines(ELSEVIER SCIENCE INC, 2019) ÇİNÇİN, AHMET ALTUĞ; Mehdiyev, S.; Velioglu, A.; Arikan, H.; Asicioglu, E.; Cincin, A.; Demirbas, T.; Tinay, I; Ozener, C.; Tuglular, S.Although cardiovascular (CV) assessment is recommended to minimize perioperative risk in all potential kidney transplant recipients, the utility and reliability of various assessment methods are not well established. In this study, we investigated the CV evaluations and outcomes of standardized CV assessment protocols (Lisbon and American Society of Transplantation [AST]) in potential kidney transplant recipients. Data were analyzed for 266 end-stage renal disease patients (mean age 45.4 +/- 13 years, female-to-male ratio 126:140) accepted for kidney transplantation wait-listing. Patients were classified as low and high cardiac risk according to their first cardiac evaluation. Major cardiovascular events (CVEs) and deaths were recorded. At the end of follow-up (median 639 days), 72 (27.1%) patients underwent kidney transplantation. A total of 49 patients (18.4%) had CVEs and 42 (15.8%) patients died. Being over 45 years of age and having dialysis vintage over 1 year were found to be independent risk factors for CVEs. Forty-eight out of 60 high-risk patients evaluated with noninvasive tests had negative results. Twelve out of these 48 patients had a CVE in due course. Among 10 patients who underwent coronary angiography, 1 had a CVE and 1 died. The sensitivity and specificity of the AST guidelines (area under the curve = 0.647, P = .005, sensitivity 83%, specificity 54%) were higher than Lisbon. In conclusion, the predictive risk factors for CVEs were age over 45 years and dialysis vintage over a year. Our results also suggest that exercise electrocardiography and myocardial perfusion scintigraphy for cardiac evaluation are less sensitive in CVE prediction. We recommend clinicians to use the AST guidelines and to prioritize coronary angiography in pretransplant CV assessment.Publication Metadata only Waist circumference is associated with carotid intima media thickness in peritoneal dialysis patients(SPRINGER, 2013) VELİOĞLU, ARZU; Asicioglu, Ebru; Kahveci, Arzu; Arikan, Hakki; Koc, Mehmet; Tuglular, Serhan; Ozener, Cetin IshakAtherosclerosis is responsible for the high mortality rate in end-stage renal disease patients. Defining risk factors for atherosclerosis may lead to reduction in cardiovascular disease through modification of these factors. Peritoneal dialysis (PD) patients are subjected to high glucose loads on a daily basis, which results in considerable weight gain and an increase in waist circumference (WC). WC as an indicator of abdominal obesity is a risk factor for atherosclerosis in the general population. Carotid artery intima media thickness (CIMT) measurement is a reliable method for the detection of early atherosclerosis. The aim of this study was to investigate the relationship between WC and CIMT and to define risk factors associated with CIMT in PD patients. Fifty-five PD patients and 40 healthy controls were included. Atherosclerosis was assessed using measurement of CIMT. Fasting blood was collected for analysis. Anthropometric parameters (age, weight, BMI, and WC) were measured. Peritoneal dialysis patients had higher WC (93.9 +/- A 1.7 vs. 87.3 +/- A 1.2 cm, p < 0.05) and CIMT (0.70 +/- A 0.02 vs. 0.57 +/- A 0.01 mm, p < 0.01) than the control group. On univariate analysis, age, WC, plaque formation, and D/P creatinine were positively correlated with CIMT, whereas residual renal function, albumin, ultrafiltration volume, and D/D0 glucose were negatively correlated. On multivariate analysis, only age, WC, and plaque formation showed correlation (p < 0.001). Carotid artery intima media thickness is associated with age, plaque formation, and WC in PD patients. WC measurement is a simple, inexpensive, reproducible, and reliable method of evaluating atherosclerosis risk in PD patients and should be assessed at every visit. Appropriate counsel should be provided to patients with greater WC who are deemed to be at risk for atherosclerosis.Publication Metadata only Sepsiste serum laktat yüksekliği-sidemi ilişkisinin böbrek fonksiyonları penceresinden incelenmesi(2022-12-08) TUĞCU, MURAT; AŞICIOĞLU, EBRU; ARIKAN, İZZET HAKKI; BARUTÇU ATAŞ, DİLEK; TUĞLULAR, ZÜBEYDE SERHAN; VELİOĞLU, ARZU; Karadağ H., Berke Menteşe İ., Barutçu Ataş D., Tuğcu M., Aşıcıoğlu E., Velioğlu A., Tuğlular Z.

K.; Ari, E.; Vayvada, M.; Salturk, C.; Asicioglu, E.; Yeginsu, A.; Kutlu, C. A.Background. Osteoporosis is a well-recognized complication in lung transplantation because of steroid use and immobilization. The aim of the study was to assess the prevalence of osteoporosis and risk factors associated with osteoporosis in lung transplantation candidates. Methods. The bone mineral density of 174 patients with various end-stage lung diseases was assessed at the pretransplantation period. Osteoporosis risk factors were analyzed with the consideration to principal diagnosis, demographic, and clinical parameters of lung disease, lung function tests and mobility test (6-minute walking test). A multivariate analysis was conducted to determine various demographic and clinical risk factors associated with bone mass loss in the pretransplant period. Results. The prevalence of osteoporosis and osteopenia was 46% and 35%, respectively, in the study population. Osteoporotic patients have lower body mass index and lower 6 minute walking distance than patients without osteoporosis. In addition, they have higher pulmonary artery pressure and history of noninvasive mechanical ventilation than in patients without osteoporosis. There was a significant negative correlation between the 6-minute walking test, body mass index, and the presence of osteoporosis in the study population. Multivariate logistic regression analysis confirmed that 6-minute walking test (odds ratio, 0.996) and body mass index (odds ratio, 0.847) were significantly and negatively correlated with the presence of osteoporosis. Conclusions. A significant proportion of patients with end-stage lung diseases have osteopenia or osteoporosis pretransplantation. This is the first study to demonstrate that 6-minute walking distance and bone mineral density independently predict osteoporosis in lung transplant candidates.Publication Metadata only Decreased Serum Selenium Levels are Correlated with Diminished Coronary Flow Reserve Among Hemodialysis Patients(HUMANA PRESS INC, 2013) AŞICIOĞLU, EBRU; Atakan, Aydin; Macunluoglu, Beyza; Kaya, Yuksel; Ari, Elif; Demir, Halit; Asicioglu, Ebru; Kaspar, CigdemCardiovascular diseases are the main reason of high mortality among hemodialysis patients. Decreased serum selenium levels may have a role in accelerated atherosclerosis in this patient group. The hypothesis of this study was to show a correlation between decreased serum selenium levels and coronary flow reserve as an indicator of endothelial dysfunction and atherosclerosis in HD patients. Seventy-one chronic hemodialysis patients and age 65 and sex-matched healthy controls were included in the study. Plasma selenium levels were measured by spectrophotometry, and coronary flow reserve was assessed by transthoracic Doppler echocardiography. Serum selenium levels (34.16 +/- 6.15 ng/ml vs. 52.4 +/- 5.51 ng/ml, P < 0.001) and coronary flow reserve values (1.73 +/- 0.11 vs. 2.32 +/- 0.28, P < 0.001) were significantly lower in hemodialysis patients compared with controls, respectively. There was a significant positive correlation between coronary flow reserve and serum levels of selenium (r = 0.676, P < 0.001). A linear regression analysis showed that serum levels of selenium were independently and positively correlated with coronary flow reserve (regression coefficient = 0.650, P < 0.05). This study was the first to show a positive and independent correlation between decreased selenium levels and diminished coronary flow reserve as an indicator of endothelial dysfunction and atherosclerosis in hemodialysis patients. Our data suggest that decreased serum selenium levels may facilitate the development of endothelial dysfunction and disruption of coronary flow reserve which occur before the development of overt atherosclerosis.Publication Metadata only Kardiyorenal sendromlu hastalarda periton diyalizi(Türkiye Klinikleri Yayınevi, 2022-09-01) BARUTÇU ATAŞ, DİLEK; AŞICIOĞLU, EBRU; Barutçu Ataş D., Aşıcıoğlu E.Kalp ile böbrek hastalığı arasındaki etkileşim çift yönlüdür. Kalbin veya böbreklerin akut veya kronik hasarı, diğer organda akut veya kronik hasara neden olabilir. Bu durum 'Kardiyorenal Sendrom' (KRS) olarak tanımlanır. Kalp yetmezliği olan hastaların %25 ile %63'ünde KRS gelişmektedir. Tedavide loop diüretikler, renin angiotensin sistem antagonistleri, tolvaptan ve ultrafiltrasyon (UF) uygulanabilir. UF, akut dekompanse kalp yetmezliği tedavisinde, diüretik direnci ve/veya böbrek fonksiyonlarında bozulma varlığında faydalı olabilir. KRS'da ultrafiltrasyon uygulamasında periton diyalizi alternatif bir tedavi yöntemidir. Hemodiyaliz ile karşılaştırıldığında, hemodinamiyi daha az etkilediği için, hipotansif komplikasyonların gelişme riski daha düşüktür ve hastaların idrarı uzun yıllar boyunca korunabilir. Rezidüel renal fonksiyonun korunması ise hasta sağ kalımı açısından avantaj sağlamaktadır. Yapılan çalışmalarda KRS tanılı hastalarda periton diyalizi ile UF yapılarak; kalp yetmezliğinin fonksiyonel sınıflaması ile sol ventrikül ejeksiyon fraksiyonunda iyileşme ve hastaneye yatış oranları ile yatış süresinde azalma olduğu gösterilmiştir.Publication Metadata only Mo174fibroscan detection of fatty liver and liver fibrosis in systemic lupus erythematosus(2021-05-01) BARUTÇU ATAŞ, DİLEK; VELİOĞLU, ARZU; ARIKAN, İZZET HAKKI; ALİBAZ ÖNER, FATMA; DİRESKENELİ, RAFİ HANER; TUĞLULAR, ZÜBEYDE SERHAN; AŞICIOĞLU, EBRU; Yetginoğlu Ö., BARUTÇU ATAŞ D., VELİOĞLU A., ARIKAN İ. H., YILMAZ Y., ALİBAZ ÖNER F., DİRESKENELİ R. H., TUĞLULAR Z. S., AŞICIOĞLU E.BACKGROUND AND AIMS: Systemic Lupus Erythematosus (SLE) is a chronic, multi-organ, systemic autoimmune disease that is more common in women than men and is typically diagnosed during the reproductive age. Although liver dysfunction is not considered the main organ pathology in SLE, the frequency of liver dysfunction or abnormal liver enzyme values may be observed in 50-60% of patients. Liver-related complications may present as asymptomatic hepatomegaly, subclinical steatosis and abnormal liver enzymes. The most common causes are drug-associated liver injury, lupus-associated hepatitis, and fatty liver disease. The aim of this study was to assess fatty liver and liver fibrosis in SLE patients using the FibroScan method as well as associated factors such as immunosuppressive medications. METHOD: Sixty SLE patients and 30 healthy controls were included. Patients with HBV, HCV or cirrhosis, malignancy, cardiac disease, or patients on dialysis were excluded. All participants underwent FibroScan measurements. Demographic data and cumulative doses of immunosuppressive medications were extracted from patient charts. Fasting blood was collected for analysis RESULTS: Demographic and clinical characteristics of the study groups are shown in Tables 1. The prevalence of fatty liver disease was similar between SLE patients and healthy controls (21.7% vs 26.7%, p= 0.597) and was associated with body mass index (BMI) (p= 0.026) and C-reactive protein (CRP) (p= 0.046) in multivariate analysis. Liver fibrosis was also similar between the two groups (26.7% vs 10.0%, p= 0.069). There was no relationship between cumulative drug doses including glucocorticoids with either fatty liver disease or liver fibrosis. Since the majority of SLE patients were female, we performed a subgroup analysis in female patients (n=51) and healthy controls (n=25). Fatty liver disease was similar between female SLE patients and healthy controls (23.5% vs 24.0%, p= 0.964). However, liver fibrosis in female patients with SLE was increased compared to the female healthy population (29.4% vs 4.0%, p= 0.011) and was associated with age (p= 0.034) and low-dose cumulative glucocorticoid use (p = 0.034). Low-dose cumulative glucocorticoid use was defined as less than 17.45 g, which was the 75th percentile value. Only 1 out of 15 female patients with fibrosis had high-dose cumulative glucocorticoid use (>17.45 g), while the remaining 14 patients had used lower doses (<17.45 g). CONCLUSION: The prevalence of fatty liver was similar between SLE patients and healthy controls, while liver fibrosis was increased in the female patient group as compared to controls. Furthermore, liver fibrosis was associated with age and low dose cumulative glucocorticoid use. Interestingly, fatty liver did not precede liver fibrosis in the majority of cases, contrary to what is observed in the general population. We hypothesized that liver fibrosis may be the result of subclinical inflammation and autoimmunity associated with SLE itself and the use of steroids may prevent or prolong fibrosis formation in the liver.Publication Metadata only Baseline carotid intima-media thickness is associated with cardiovascular morbidity and mortality in peritoneal dialysis patients(WILEY, 2021) VELİOĞLU, ARZU; Asicioglu, Ebru; Velioglu, Arzu; Arikan, Hakki; Koc, Mehmet; Tuglular, Serhan; Ozener, CetinCarotid intima-media thickness (CIMT) is an early marker of atherosclerosis and is increased in peritoneal dialysis (PD) patients. Association of CIMT with cardiovascular disease (CVD) or mortality is less clear. Fibroblast growth factor-23 (FGF-23) is a hormone associated with vascular calcification, atherosclerosis, and mortality in the hemodialysis population. We investigated whether baseline CIMT and FGF-23 are associated with CVD and mortality in PD patients. Fifty-five PD patients were included. CVD was defined as ischemic heart disease, stroke, or peripheral artery disease. Intact FGF-23 was measured in plasma. CIMT was measured by ultrasonography. Twenty-one patients developed CVD and 12 died over 47.1 +/- 33.8 months. Patients with CVD were older (55.9 +/- 10.5 vs. 42.5 +/- 12.9 years, P < .01), had lower albumin (3.8 +/- 0.5 vs. 4.2 +/- 0.3 g/dL, P < .01) and higher CIMT (0.87 +/- 0.22 vs. 0.61 +/- 0.11 mm, P < .01). Patients with mortality were also older (53.5 +/- 11.5 vs. 45.8 +/- 13.8 years, P = .05), had lower albumin (3.7 +/- 0.6 vs. 4.1 +/- 0.3 g/dL, P < .01), higher CRP (15.0 +/- 8.5 vs. 7.6 +/- 8.4 mg/L, P < .01) and CIMT (0.9 +/- 0.3 vs. 0.6 +/- 0.1 mm, P < .01). Albumin and CIMT were associated with CVD and CIMT > 0.75 mm was associated with cardiovascular mortality. FGF-23 did not show any correlations. CIMT at baseline is associated with CVD and mortality in PD patients.Publication Metadata only The Correlation of Serum Trace Elements and Heavy Metals with Carotid Artery Atherosclerosis in Maintenance Hemodialysis Patients(HUMANA PRESS INC, 2011) AŞICIOĞLU, EBRU; Ari, Elif; Kaya, Yuksel; Demir, Halit; Asicioglu, Ebru; Keskin, SiddikChanges in essential trace elements and heavy metals may affect the atherosclerotic state of patients on maintenance hemodialysis (HD). The aim of the study was to evaluate the relation between the serum levels of some trace elements and heavy metals (iron, zinc, manganese, copper, magnesium, cobalt, cadmium, lead, and copper/zinc ratio) and carotid artery intima-media thickness (CIMT) in HD patients. Fifty chronic HD patients without known atherosclerotic disease and 48 age- and sex-matched healthy individuals were included in the study. The serum levels of trace elements (iron, zinc, manganese, copper, and magnesium) and heavy metals (cobalt, cadmium, and lead) were measured by Atomic Adsorption Spectrophotometer (UNICAM-929). CIMT was assessed by carotid artery ultrasonography. The serum levels of iron, zinc, and manganese were lower; levels of copper, magnesium, cobalt, cadmium, lead, and copper/zinc ratio were higher in HD patients compared to controls. CIMT in HD patients were higher than the control group (0.64 +/- 0.11 vs 0.42 +/- 0.05, p < 0.001). There was a significant negative correlation between CIMT and serum levels of zinc (r = -0.70, p < 0.01), iron (r = -0.71, p < 0.01), and manganese (r = -0.47, p < 0.01), while there was a significant positive correlation between CIMT and serum levels of copper (r = 0.63, p < 0.01), magnesium (r = 0.77, p < 0.01), cobalt (r = 0.63, p < 0.01), cadmium (r = 0.48, p < 0.01), lead (r = 0.38, p < 0.01), and copper/zinc ratio (r = 0.68, p < 0.01). A linear regression analysis showed that serum levels of magnesium, cadmium, lead, and copper/zinc ratio were still significantly and positively correlated with CIMT. We propose that copper/zinc ratio, magnesium and toxic metals cadmium and lead are independent determinants of CIMT in maintenance HD patients without known atherosclerotic disease.
