    (2020) Tekkarismaz, Nihan; Torun, Dilek; 0000-0001-7631-7395; 0000-0002-6267-3695; 32041385; AAD-9088-2021; AAD-9111-2021
    Background/aim: The aim of this study was to evaluate the clinical outcomes and identity the predictors of mortality in peritoneal dialysis patients. Materials and methods: Medical records of all incident peritoneal dialysis (PD) patients followed up between January 2011 and May 2019 were reviewed retrospectively. All patients were followed up until death, renal transplantation, transfer to haemodialysis or the end of the study Results: A total of 242 patients were included in thestudy: The incidence of peritonitis was 0.18 (ranging from 0 to 14.9) episodes per patient year. Death occurred in 280 (n: 68) of cases. Age, diabetes mellitus, malignancy and refractory heart failure were independent risk factors for all-cause mortality according to multivariate analysis. 'the presence of comorbid disease and diabetes mellitus and patients aged > 65 years were associated with increased risk of mortality and decreased patient survival. Peritonitis history was associated with increased risk of mortality Between peritonitis and peritonitis-free group, there was no significant difference in Kaplan-Meier curves in terms of patient survival. Conclusion: This is the first study to define 9-year mortality predictors in PD patients in our centre. Although peritonitis is the most feared complication of PD, our study showed that peritonitis did ot reduce patient survival.

    Experience with antiviral agents for treatment of hepatitis C virus infection in hemodialysis patients on the kidney wait list
    (2019) Torun, Dilek; Soydas, Baris; Tekkarismaz, Nihan; Ozelsancak, Ruya; Micozkadioglu, Hasan; Haberal, Mehmet; 30762283
    Introduction Hepatitis C virus (HCV) infection is associated with increased mortality and morbidity in kidney transplant patients. The ability to establish a sustained viral response before renal transplant is important for these patients. Direct-acting antiviral agents can increase the sustained viral response in most patients with HCV infection. In this case series, we aimed to determine the efficacy and safety of a combined therapy of ombitasvir, paritaprevir, ritonavir, and dasabuvir with or without ribavirin in patients with HCV genotype 1 infection without cirrhosis and on hemodialysis who were awaiting deceased-donor kidney transplant. Methods Our study included eight male and two female HCV ribonucleic acid (RNA)-positive hemodialysis patients (mean age 50.7 +/- 15 years, mean hemodialysis duration 14 +/- 5.5 years, mean HCV duration 18 +/- 3.7 years). Findings Three patients with genotype 1a received oral therapy with 12.5 mg ombitasvir, 150 mg paritaprevir, 7 5 mg ritonavir, and 250 mg dasabuvir plus 200 mg ribavirin for 12 weeks. Seven patients with genotype 1b received 12.5 mg ombitasvir, 150 mg paritaprevir, 75 mg ritonavir, and 250 mg dasabuvir without ribavirin treatment for 12 weeks. The sustained virologic response rate was 100% at 12 weeks after completion of antiviral treatment in both treatment groups. No serious adverse effects were observed in either treatment group. Five patients had constitutional symptoms such as nausea, anorexia, and fatigue. During the treatment period, hemoglobin, white cell blood count, thrombocyte, and ferritin levels were similar to pretreatment levels. Treatment did not affect weekly erythropoietin and monthly intravenous iron treatment doses. Discussion Direct-acting antiviral agents are safe and effective for generating a sustained viral response in HCV genotype 1-infected hemodialysis patients on kidney wait lists.

    Heart Valve Disease Predict Mortality in Hemodialysis Patients: A Single Center Experience
    (2019) Ozelsancak, Ruya; Tekkarismaz, Nihan; Torun, Dilek; Micozkadioglu, Hasan; 0000-0002-0788-8319; 30421548
    Our aim is to investigate the clinical and laboratory findings affecting the mortality of the patients in 3 years follow-up who underwent hemodialysis at our center. In this retrospective, observational cohort study, 432 patients who underwent hemodialysis at our center for at least 5 months were included. The first recorded data and subsequent clinical findings of patients who died and survived were compared. Two hundred and ninety patients survived, 142 patients died. The mean age of the patients who died was higher (63.4 +/- 12.3 years, vs. 52 +/- 16.1 years, P = 0.0001), 60.5% of them had coronary artery disease (P = 0.0001), 93.7% of them had a heart valve disease. Duration of hemodialysis (survived 57 [21-260] months; died 44 [5-183] months, P = 0.000) was lower in patients who died. Serum potassium level before dialysis (5.1 +/- 0.6; 4.9 +/- 0.7 mEq/L, P = 0.030), parathyroid hormone (435 [4-3054]; 304 [1-3145] pg/mL, P = 0.0001), albumin (3.9 +/- 0.4; 3.8 +/- 0.4 mg/dL, P = 0.0001) and Kt/V (1.48 +/- 0.3; 1.40 +/- 0.3, P = 0.019) levels were lower, C-reactive protein (5[1-208]; 8.7[2-256] mg/L, P = 0.000) levels were higher in patients who died. Logistic regression analysis showed age (OR = 1.1), coronary artery disease (OR = 1.7) and more than one heart valve disease (OR = 2.4) are independent risk factors for mortality. Potassium level before dialysis (OR = 0.60), parathyroid hormone (OR = 0.99), and higher Kt/V (OR = 0.28) were found to be an advantage for survival. Age, coronary artery disease and especially pathology in more than one heart valve are risk factors for mortality. Heart valve problems might develop because of malnutrition and inflammation caused by the chronic renal failure.
