Item Factors Associated with Fibromyalgia Syndrome in Peritoneal Dialysis Patients(2019) Ozelsancak, Ruya; Analan, Pinar Doruk; Leblebici, Berrin; 0000-0002-3528-3712; 0000-0002-0788-8319; 30787502; AAA-8043-2021; AAD-5716-2021Purpose: We evaluated the prevalence of fibromyalgia syndrome (FMS) in peritoneal dialysis (PD) patients and whether this syndrome is associated with gender, age, duration of PD, or other laboratory parameters. Methods: A total of 60 chronic PD patients (26 women, 34 men) and 60 healthy controls (30 women, 30 men) were included. We recorded each participant's age, gender, cause of kidney failure, PD duration, laboratory parameters, education level, and symptoms related to FMS, diagnosed according to the 2010 American College of Rheumatology criteria. Results: Eleven patients (18%) in the PD group and nine (15%) in the control group met the diagnostic criteria for FMS. There were no statistically significant differences in age; gender; education level; PD duration; laboratory parameters; or sleepdisturbance, fatigue, or cognitive symptoms between the FMS and non-FMS groups among the PD patients. We next compared control and PD patients with FMS. Both groups were of a similar age and gender and had similar sleep disturbance and cognitive symptoms, but more patients had fatigue in the control group. Conclusions: The prevalence of FMS among PD patients was similar to that in the general population, and FMS was not associated with gender, age, duration of PD, or other laboratory parameters.Item Cerebrovascular events in hemodialysis patients; a retrospective observational study(2019) Ozelsancak, Ruya; Micozkadioglu, Hasan; Torun, Dilek; Tekkarismaz, Nihan; 0000-0002-0788-8319; 31830923Background This study reports findings in subjects who underwent brain imaging for any reason, and examined factors influencing cerebrovascular events (CVEs) in hemodialysis (HD) patients. Methods We reviewed the files of patients on HD between January 2015 and January 2018. A total of 432 patients who underwent HD for at least 5 months by the January 2015 and who were older than 18 years were included in the study; 264 had been examined by cerebral computed tomography or magnetic resonance imaging examination within the 3 years. Cerebrovascular pathology was detected in 139 of 264 patients. Results Of the 139 patients, 65 (24.62%) had ischemic lesions, 25 (9.47%) had hemorrhagic lesions, and 49 (18.56%) had cerebral small vessel disease (CSVD). We compared recorded data and later clinical findings between patients with and those without CVEs. The cause of end-stage renal disease was diabetes in 58.5% of patients with ischemic lesions, 52% in those with hemorrhagic lesions, and 55% in those with CSVD (P < 0.05). Patients with cerebrovascular ischemia were older (P = 0.0001) and had lower serum creatinine (sCr) (P = 0.0001) and higher serum C-reactive protein (CRP) (P = 0.002) levels than normal subjects. Hemorrhagic patients were older (P = 0.003) and had lower sCr (P = 0.003) and serum predialysis potassium (P = 0.003) and parathyroid hormone (PTH) (P = 0.004) levels than normal subjects. Patients with CSVD were older (P < 0.0001) and had lower sCr (P < 0.0001), phosphorus (P < 0.007), and PTH (P < 0.013) and higher CRP (P < 0.002) levels than normal subjects. Conclusions HD patients with CVEs are older and typically have diabetes mellitus and lower sCr levels.Item The Effects of Cinacalcet Treatment on Bone Mineral Metabolism, Anemia Parameters, Left Ventricular Mass Index and Parathyroid Gland Volume in Hemodialysis Patients with Severe Secondary Hyperparathyroidism(2016) Torun, Dilek; Yildiz, Ismail; Micozkadioglu, Hasan; Nursal, Gul Nihal; Yiğit, Fatma; Ozelsancak, Ruya; 26787561The aim of this study was to investigate the effects of cinacalcet therapy on anemia parameters, bone mineral metabolism, left ventricular mass index (LVMI) and parathyroid gland volume in hemodialysis (HD) patients with secondary hyperparathyroidism. Twenty-five HD patients (M/F: 11/14, mean age: 45.2 +/- 17.9 years, mean HD duration: 96.4 +/- 32.7 months) were included in this prospective pilot study. The indication to start calcimimetic therapy was persistent serum levels of parathyroid hormone (PTH) > 1000 pg/mL, refractory to intravenous (i.v.) vitamin D and phosphate-binding therapy. The initial and one-year results of adjusted serum calcium (Ca+2), phosphate (P), Ca x P product, PTH, hemoglobin (Hb) and ferritin levels, transferrin saturation index (TSAT), median weekly erythropoietin (EPO) dose, LVMI, and parathyroid volume by parathyroid ultrasonography were determined. There were no differences between pre-and posttreatment levels of serum Ca+2 (P = 0.853), P (P = 0.447), Ca x P product (P = 0.587), PTH (P = 0.273), ferritin (P = 0.153) and TSAT (P = 0.104). After 1 year of calcimimetic therapy, the Hb levels were significantly higher than the initial levels (P = 0.048). The weekly dose of EPO decreased with no statistical significance. The dose of cinacalcet was increased from 32.4 +/- 12.0 to 60.0 +/- 24.4 mg/day (P = 0.01). There were no differences between the pre-and post-treatment results regarding weekly vitamin D dose, parenteral iron dose, LVMI and parathyroid volume. The results of our study suggest that cinacalcet therapy might have an additional benefit in the control anemia in HD patients.Item p.R301X Mutation and Variable Phenotypic Appearance of Fabry Disease(2016) Ozelsancak, Ruya; Uyar, Bulent; 27156739Patient: Male, 39 Final Diagnosis: Fabry disease Symptoms: - Acropareshesia . fatique Medication: - Clinical Procedure: Gene analysis Specialty: Metabolic Disorders and Diabetics Objective: Rare disease Background: Fabry disease is an X-linked disorder. Due to deficiency of the enzyme a-galactosidase A, neutral glycosphingolipids (primarily globotriaosylceramide) progressively accumulate within lysosomes of cells in various organ systems, resulting in a multi-system disorder, affecting both men and women. Misdiagnosis and delayed diagnosis are common because of the nature of Fabry disease. Case Report: We report a case of Fabry disease with a p. R301X (c. 901 C> T) mutation in a 39-year-old man who was being treated for chronic sclerosing glomerulonephritis for 2 years. Family screening tests showed that the proband's mother, sister, and daughter had the same mutation with different phenotypes. Levels of a-galactosidase A were low in the proband and his mother and sister. Cornea verticillata and heart involvement were present in multiple family members. Agalsidase alfa treatment was started in patients where indicated. Conclusions: Pedigree analysis is still a powerful, readily available tool to identify individuals at risk for genetic diseases and allows earlier detection and management of disease.Item Listeriosis in a Patient Undergoing Hemodialysis: A Case Report and Review of the Literature(2017) Tekkarismaz, Nihan; Ozelsancak, Ruya; Torun, Dilek; Aliskan, Hikmet Eda; 0000-0001-7631-7395; 0000-0001-9060-3195; 0000-0002-0788-8319; 0000-0002-6267-3695; AAD-9088-2021; AAE-2282-2021; AAD-5716-2021; AAD-9111-2021Listeria monocytogenes (L. monocytogenes) infection is an uncommon manifestation in patients with chronic renal failure. In this article, we present a case of L. monocytogenes bacteremia in a patient undergoing hemodialysis. In addition, we are also present the listeriosis cases in hemodialysis patients reported so far in the literature. The patient was a 58-year-old man who was undergoing hemodialysis and had been admitted to hospital with fever. On the 5th day of admission, L. monocytogenes was detected in his blood cultures. He responded dramatically to ampicillin treatment. Listeriosis is a disease that requires careful microbiological laboratory examination. If the patient cultures are not analyzed carefully, the disease can be misdiagnosed. Only early diagnosis and adequate treatment can ensure a good prognosis.
