Publication Open Access Low bone density, vertebral fracture and FRAX score in kidney transplant recipients: A cross-sectional cohort study(PUBLIC LIBRARY SCIENCE, 2021-04-30) VELİOĞLU, ARZU; Velioglu, Arzu; Kaya, Burcu; Aykent, Basar; Ozkan, Bige; Karapinar, Melis Sevil; Arikan, Hakki; Asicioglu, Ebru; Bugdayci, Onur; Yavuz, Dilek Gogas; Tuglular, SerhanBackground Kidney transplantation (KT) recipients are at increased risk of low bone density (LBD) and fractures. In this retrospective study, we investigated bone mineral density (BMD), vertebral fractures, calculated risk for major osteoporotic fractures (MOF), and hip fractures in the KT recipients. Patients-method Patients who completed at least one year after KT were included in the analysis. Demographic, clinical, and laboratory data were recorded. Measurements of BMD were performed by dual-energy X-ray absorptiometry. Vertebral fractures were assessed using semi-quantitative criteria with conventional radiography. The ten-year risk for MOF and hip fracture were calculated using the FRAX@ tool with BMD. Results One hundred fifty-three KT recipients were included in the study. The population included 77 women. The mean age at evaluation was 46,511,9 years. Seventy-eight (50.9%) patients had normal femoral neck BMD while osteoporosis and osteopenia at the femoral neck were present in 12 (7.8%) and 63 (41.1%) of the patients, respectively. Age at evaluation was the risk factor for LBD (OR 1.057; 95% CI 1.024-1.091; p = 0.001). In female KT recipients, LBD was principally affected by menopausal status whereas in males, mammalian target of rapamycin (mTOR) inhibitor use and lower BMI levels were the risk factors. The prevalent vertebral fracture was found in 43.4% of patients. In multivariate analysis, only steroid use (OR 0.121; 95% CI 0.015-0.988; p = 0.049) was found to be associated with prevalent fracture. Among all KT recipients, 1.9% had a high MOF probability (>= 20% risk of fracture), and 23.5% had high hip fracture probability (>= 3% risk of hip fracture) according to FRAX. Conclusion Exploring the prevalence of LBD and vertebral fracture and the risk factors would help clinicians to modify long-term follow-up strategies. Furthermore, the high hip fracture risk probability in our cohort suggested that there is a need for longitudinal studies to confirm the validity of the FRAX tool in the transplant population.Publication Open Access Recommendations for kidney patients in covid-19 era based on current evidence(2022-01-01) VELİOĞLU, ARZU; TUĞLULAR, ZÜBEYDE SERHAN; Ozturk S., VELİOĞLU A., TUĞLULAR Z. S.Patients with chronic kidney disease, patients on dialysis, and kidney transplant recipients are at high risk of mortality and morbidity due to coronavirus disease-19. Most patients with chronic kidney disease are elderly and have other comorbidities. In addition, some of these patients have been exposed to immunosuppressive drugs to treat their underlying primary disease or to prevent allograft rejection. This general profile of chronic kidney disease patients renders them susceptible to a more severe course of coronavirus disease-19 once they are infected with severe acute respiratory syndrome coronavirus 2. Many studies showed that impaired kidney function on admission is an independent risk factor for a more severe course of coronavirus disease-19 with significantly increased risk for hospital and intensive care unit admission, intubation, mechanical ventilation, and death. Coronavirus disease-19 vaccination is crucial to create immunity in the general community, but the evidence addressing this specific population is scarce. However, based on the current evidence, all patients with chronic kidney disease are strongly recommended to receive the available vaccine in their country against coronavirus disease-19, and booster doses will presumably prove necessary for this group of patients. Furthermore, vigilant use of protective measures is strongly recommended for this patient population. Current studies and recommendations from health authorities should be followed closely.Publication Open Access Peritoneal dialysis-related peritonitis with an unexpected micro-organism: enterococcus hirae(2017-01-01) BARUTÇU ATAŞ, DİLEK; AŞICIOĞLU, EBRU; VELİOĞLU, ARZU; TUĞLULAR, ZÜBEYDE SERHAN; ARIKAN, İZZET HAKKI; BARUTÇU ATAŞ D., AYKENT M. B., AŞICIOĞLU E., ARIKAN İ. H., VELİOĞLU A., TUĞLULAR Z. S., ÖZENER İ. Ç.Enterococcus Hirae is a gram-positive, facultative, anaerobic bacterium which is usually a zoonotic pathogen rarely isolated from human infections. There are no published reports describing continuous ambulatory peritoneal dialysis (CAPD) related- peritonitis with Enterococcus Hirae in the literature. With the following report, we describe the case of peritoneal dialysis (PD)-related peritonitis due to Enterococcus Hirae.Publication Open Access Care of asymptomatic SARS-CoV-2 positive kidney transplant recipients(WILEY, 2020-10) VELİOĞLU, ARZU; Velioglu, Arzu; Tuglular, SerhanPublication Open Access Low-dose valacyclovir use with preemptive monitoring in kidney transplant recipients with intermediate cytomegalovirus infection risk(2022-01-01) VELİOĞLU, ARZU; ARIKAN, İZZET HAKKI; AŞICIOĞLU, EBRU; TUĞLULAR, ZÜBEYDE SERHAN; AKSU, MEHMET BURAK; VELİOĞLU A., Alagoz S., Atas D.

Case report and review of the literature(MARMARA UNIV, FAC MEDICINE, 2017-01-15) VELİOĞLU, ARZU; Barutcu Atas, Dilek; Arikan, Hakki; Aykent, Basar; Asicioglu, Ebru; Velioglu, Arzu; Tuglular, Serhan; Ozener, CetinKocuria kristinae is a gram-positive coccus of Micrococcaceae family. Kocuria kristinae inhabits the skin and mucous membranes. It can cause opportunistic infections in patients with indwelling devices and severe underlying diseases. We describe here a case of acute peritonitis caused by Kocuria kristinae in a patient on continuous ambulatory peritoneal dialysis (CAPD). Additionally, a review of other reported CAPD related peritonitis by Kocuria kristinae is provided. The importance of Kocuria kristinae as a pathogen in patients with CAPD peritonitis should not be underestimated.Publication Open Access Prediction of subclinical left ventricular dysfunction by speckle-tracking echocardiography in patients with anti-neutrophil cytoplasmic antibody--associated vasculitis(2021-12-24) İZGİ, TUBA NUR; ATAŞ, HALİL; VELİOĞLU, ARZU; BARUTÇU ATAŞ, DİLEK; ILGIN, CAN; ALİBAZ ÖNER, FATMA; DİRESKENELİ, RAFİ HANER; ARIKAN, İZZET HAKKI; TUĞLULAR, ZÜBEYDE SERHAN; AŞICIOĞLU, EBRU; Izgi T. N., Atas D., ATAŞ H., Akaslan D., Ilgin C., VELİOĞLU A., ARIKAN İ. H., Alibaz-Oner F., DİRESKENELİ R. H., TUĞLULAR Z. S., et al.Objectives: This study aims to evaluate left ventricular functions using speckle-tracking echocardiography (STE) in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Patients and methods: Between June 2018 and July 2019, a total of 31 AAV patients (17 males, 14 females; median age: 53 years; range, 47 to 62 years) and 21 healthy controls (11 males, 10 females; median age: 56 years; range, 46 to 60 years) were included in the study. Clinical and biochemical characteristics of all participants were recorded. All participants underwent conventional and two-dimensional STE. The receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value of serum N-terminal prohormone of brain natriuretic peptide (NT-pro-BNP) that predicted subclinical left ventricular dysfunction. The Spearman correlation analysis was used to determine the correlation between left ventricular global longitudinal strain (LV-GLS) and NT-pro-BNP. Results: The LV-GLS was lower in AAV patients (19.3% vs. 21.7%, respectively; p=0.014). NT-pro-BNP was negatively correlated with LV-GLS (p=0.005, r=0.401). Conclusion: Subclinical left ventricular dysfunction can be detected by STE in patients with AAV who have free of clinically overt cardiovascular disease. The LV-GLS is negatively correlated with serum NT-pro-BNP levels.Publication Open Access A case of alport syndrome with pregnancy-related atypical hemolytic uremic syndrome, andcrescentic glomerulonephritis(2021-05-01) BERKE MENTEŞE, İLAY; TUĞCU, MURAT; VELİOĞLU, ARZU; TUĞLULAR, ZÜBEYDE SERHAN; BERKE MENTEŞE İ., TUĞCU M., VELİOĞLU A., Nazlı İ., TUĞLULAR Z. S.BACKGROUND: Thrombotic microangiopathy (TMA) is one of the most important complications in pregnant patients with chronic kidney disease (CKD) causing clinical deterioration. However, little is known about the pregnancy course in women with Alport syndrome (AS). CASE: A 28-week pregnant, 22-year-old woman was admitted to our clinic because of widespread edema. Her medical history was notable only for hearing impairment. On examination, vital signs were normal except for the blood pressure (150/90 mmHg). There were diffuse crackles at the lung bases, and 3þ pitting edema in both legs. Lab results revealed heavy proteinuria with 11 gr/day and isomorphic erythrocytes with granular casts in microscopic urine examination. An emergency c-section was performed due to severe preeclampsia at 30 weeks’ gestation. After delivery, her edema did not improve, serum creatinine and lactate dehydrogenase levels elevated, anemia and thrombocytopenia developed (Table 1). Additional tests revealed negative Coombs test, schistocytes on peripheral smear and normal ADAMTS13 level. There was no pathology in serological studies. She received four sessions of plasmapheresis therapy, and with the diagnosis of aHUS, eculizumab therapy was started. Despite improving thrombocytopenia and anemia, serum creatinine levels continued to rise and her urine output decreased. A kidney biopsy was performed (Figure 1). In the light microscopy, 11 of 15 glomeruli had circumferential cellular crescents and 4 had partial cellular crescents. The sample had no findings consistent with TMA. No staining was seen with IgG, IgA, IgM, C3, C1q, j and k in immunofluorescence.Publication Open Access Unusual presentation of peritonitis with persistent clear aspirate: a case report(2010-12) VELİOĞLU, ARZU; Asicioglu, Ebru; Kahveci, Arzu; Bakir, Elif Ari; Bulur, Atilla; Arikan, Hakki; Koc, Mehmet; Tuglular, Serhan; Ozener, CetinPublication Open Access Impact of the Anatomical Localization of the Exit Site on Complications in Patients on Peritoneal Dialysis(AVES, 2021-06-17) VELİOĞLU, ARZU; Tugcu, Murat; Velioglu, Arzu; Asicioglu, Ebru; Arikan, I. Hakki; Tuglular, Z. SerhanBackground: Infections are the most common complications in patients with peritoneal dialysis (PD). The association between the anatomical localization of the exit site (ES) and infectious complications is unclear. In this study, we evaluated the relationship between the anatomic location of the ES and infectious complications of PD. Methods: We examined the ES of 53 patients on PD. To define the anatomical localization of the ES, its distance from the line between right and left anterior superior iliac spines (A line), umbilicus (B line), and the anterior superior iliac spine on the catheter side (C line) was measured. Results: Coiled catheters were used in all patients. The mean lengths of A line, B line, and C line were 4.1 +/- 2.2 cm (range, 0-9.5 cm), 9.6 +/- 2.9 cm (range, 4-17 cm), and 9.3 +/- 2.9 cm (range, 5-18 cm), respectively. ES infection was documented in 9 patients (17%), tunnel infection in 1 patient (2%), and peritonitis in 27 (50.9%) patients. The B line was significantly longer in those with peritonitis than those without peritonitis (10.6 +/- 3 vs. 8.7 +/- 2.7 cm; P = .036). Other variables were not associated with infectious complications. Conclusion: There was an association between the anatomical localization of the ES and the development of peritonitis. An ES close to the umbilicus could reduce the risk of peritonitis by enabling access by the patient to perform daily care.
