Abstract
INTRODUCTION Peritoneal dialysis (PD) is one of the kidney replacement therapies (KRT). Patients' choice of KRT is influenced by personal causes, familial factors, factors related to healthcare professionals, and social factors. METHODS This study included 341 patients. PD patients who changed their KRT selection were asked for the reasons to change with a questionnaire. RESULTS Of the patients who initially chose PD, only 48.5% received KRT by PD. Five (20%) of the patients gave up PD compulsorily because they heard that the risk of infection with PD was higher, eight (40%) thought they could not do it, four (20%) because they needed to do assisted PD but had no relatives to do it, and three (15%) because they had abdominal surgery. CONCLUSION We believe that the fact that KRT training is carried out by a PD trained team and that patients are provided with assistance for PD will be effective in addressing the concerns of patients with PD undecided.

Abstract
BACKGROUND The prevalence of obesity is increasing worldwide. Obesity is also increasing in the chronic kidney disease (CKD) population. There are conflicting data on complications such as mortality, peritonitis, and technique proficiency of peritoneal dialysis (PD) in underweight and obese patients according to body mass index (BMI). We aimed to present the data in our region to the literature by comparing the residual renal function (RRF), peritonitis, technique proficiency, and mortality rates of the patients we grouped according to BMI. METHODS The data of 404 patients who were started and followed up in our clinic between March 2005 and November 2021 were evaluated retrospectively. They were grouped as underweight, normal weight, overweight, and obese according to BMI. RRF, mortality, technique proficiency and peritonitis data of the groups were compared. RESULTS Of the 404 patients, 44 were underweight, 199 were normal weight, 110 were overweight, and 55 were obese. No difference was found between the groups in the technique survey and in the time to first peritonitis with Kaplan-Meier analysis (respectively; p = 0.610, p = 0.445). Multivariate Cox regression analysis showed that BMI did not affect mortality (HR 1.196 [95% CI 0.722-1.981] (p = 0.488)). CONCLUSION In conclusion, we report that BMI has no effect on RRF, peritonitis, technique proficiency, and mortality in patients undergoing PD, and that mortality may depend on additional factors such as mean albumin, time to first peritonitis, and loss of RRF.

Abstract
BACKGROUND With a global increase in life expectancy around the world, the burden of chronic kidney disease in the elderly is increasing. The number of elderly patients undergoing peritoneal dialysis (PD) is also increasing. There is still a perception that PD may be associated with an increased risk of complications in these elderly patients. METHODS A total of 311 patients, of which 103 PD patients aged 65 and over and 208 PD patients under 65 years of age, were followed in a single center and evaluated, retrospectively. Demographic data of these patients, albumin values at first PD and during PD time, residual urine amount, number of peritonitis, time to the first peritonitis attack, PD endpoints, and mortality were compared. RESULTS Peritonitis and technique failure rates were lower in patients aged 65 and over who applied PD (0.61-0.75, 6.8%-23.1%, respectively). There was no difference in peritonitis-free survival (p = 0.931). Need for help HR 2.569 [95%CI 1.564-4.219] (p < 0.05), time to first peritonitis attack HR 0.983 [95%CI 0.974-0.992] (p < 0.05), mean albumin value HR 0.191 [95%CI 0.088-0.413] (p < 0.05), urine output level HR 1.154 [95%CI 1.010-1.318] (p < 0.05) were factors affecting mortality. CONCLUSION Peritonitis and technical survival evaluations of elderly PD patients, other than mortality, were lower than younger PD patients. However, the need for help is one of the biggest obstacles to this method for the elderly. We believe that incentives in this regard will increase the number of elderly PD patients.

Abstract
OBJECTIVE In this study, we examined the mandibular trabecular bone structures by performing fractal dimension (FD) analysis in patients who underwent renal transplantation (RTx). METHODS Our study is an observational study with 69 RTx patients and 35 control group patients. The mean FD values of the patient and control groups were calculated and compared. In addition, biochemical parathyroid hormone (PTH), serum calcium, phosphorus, alkaline phosphatase (ALP), and vitamin-D parameters and FD values of both groups were analyzed. RESULTS FD values were significantly lower in the patient group than in the healthy group (p < .05). In the RTx group compared to the control group, ALP (90.71 ± 34.25-66.54 ± 16.8, respectively) (p < .001) and PTH (75.76 ± 38.01-38.17 ± 12.39, respectively) (p < .001) values were higher. There was a positive correlation between the FD values and ALP (rspearman = .305, p = .011) and a negative correlation between FD values and vitamin-D (rspearman = .287, p = .017) of patients with RTx. CONCLUSION FD values were found to be lower in patients who underwent RTx compared to the control group. It should be considered that FD analysis can be a method that can be used to evaluate trabecular bone structure in patients undergoing RTx.

Abstract
BACKGROUND The relationship between hypoalbuminemia in peritoneal dialysis (PD) and mortality, risk of peritonitis, and decreased residual renal function (RRF) is known. However, we have not encountered a comprehensive study on which of the mean albumin values, at the beginning of peritoneal dialysis, in the first year, and during the peritoneal dialysis period, provide more predictive predictions regarding mortality, peritonitis risk, and RRF reduction. METHODS A total of 407 PD patients in whom PD was initiated and followed up and PD was terminated were included in the study. Albumin levels, peritonitis, and RRF at the beginning of PD and at 3-month periods during PD were recorded. RESULTS In the evaluation of the patients, there was a significant relationship between mean, first-year albumin values in RRF loss (p = 0.001, p = 0.006, respectively) and peritonitis (p < 0.001), but no significant correlation was found with baseline albumin values (p = 0.213, p = 0.137, respectively). In the comparison of mortality ROC analysis of PD patients, a significant correlation was found with mortality at baseline, first year, and mean albumin values (p < 0.001). However, in the multivariate Cox regression analysis, it was determined that there was a more significant relationship between first-year albumin and mean albumin values compared to baseline albumin values (HR 0.918 [95% CI 0.302-0.528] (p < 0.001)), (HR 1.161 [95% CI 0.229-0.429] (p < 0.001)), (HR 0.081 [95% CI 0.718-1.184] (p = 0.525)). CONCLUSIONS In conclusion, mean and first-year mean albumin levels provide more determinative predictions for mortality, risk of peritonitis, and maintenance of residual renal functions in peritoneal dialysis patients compared to baseline albumin.

Abstract
BACKGROUND It has been reported that living far from the peritoneal dialysis (PD) unit is a risk factor for peritonitis. Considering that PD units are urban located; the question of whether living in a rural area compared to an urban area is a risk factor for peritonitis has arisen. METHODS From March 2010 to August 2020, 335 episodes of peritonitis in 202 PD patients followed in a single center were evaluated retrospectively. People living in areas with a population <1000 were defined as living in rural areas regardless of their distance from the PD center. Cox regression analysis was used to identify independent factors associated with peritonitis. RESULTS A total of 202 PD patients were followed during 791 patient-years (mean follow-up of 3.9 years per patient). Total patients had 335 episodes of peritonitis and the rate of peritonitis was 0.42 episodes per year (episodes/patient-year). Cox regression analysis revealed that living environment (urban vs. rural) was not a risk factor for peritonitis (p = 0.57). CONCLUSIONS In Turkey, we report that living in a rural area in our region is not a risk factor for peritonitis. It is not the right approach for both the physician and the patient to be reluctant in the choice of PD due to the concern of peritonitis in rural areas.

Abstract
Systemic lupus erythematosus (SLE) is a disease of the immune system with an unknown etiology. It is a unique disease that has a wide range of clinical and laboratory findings according to the organ or system involved and the activity of the disease. Mean platelet volume (MPV) is a simple parameter of the blood and is widely and easily available. It has been evaluated as a sign of inflammation in many kinds of diseases recently. In this study, we retrospectively analyzed the laboratory parameters and clinical features of 36 SLE patients with renal involvement and nephrotic-range proteinuria in the active and remission periods of the disease between 2005 and 2013. We found that the mean MPV in the active disease of the period was statistically significantly higher than in the remission period (8.30 ± 1.09 and 7.88 ± 0.7, respectively, P = 0.007).

Abstract
INTRODUCTION There is no consensus on an ideal marker of oxidative stress (OS). Disruption of the balance between free radical and antioxidant activity production by increasing oxidative markers results in OS. In this study, we aimed to investigate how OS, which increases mortality and morbidity due to various reasons, is affected by keto/amino therapy in patients with hypoalbuminemia undergoing peritoneal dialysis. MATERIALS AND METHOD Twenty patients who underwent peritoneal dialysis were included in the study. Before starting keto/amino acid therapy, primary kidney diseases were determined, body mass indexes, serum total protein, albumin, C-reactive protein, ferritin, calcium, phosphorus, parathyroid hormone, paraoxonase-1 (PON-1), sialic acid levels, arylesterase (ARE) activities, and malondialdehyde (MDA) levels were measured, and Kt/V values were calculated. Keto/amino acid treatment was initiated for those with an albumin level of <3.5 g/dL. The same parameters of the patients, followed up for 3 months, were checked again at the end of the third month. RESULTS Paraoxonase-1 and ARE activities, which are antioxidant enzyme activities, were found to be statistically significantly increased compared to the initial period (59 ± 59, 135 ± 69, 15.8 ± 19.7, and 44.7 ± 16.4, respectively; p < 0.00). MDA and sialic acid levels were significantly lower than the initial values (109 ± 99, 23 ± 9, 2.26 ± 0.44, and 2.04 ± 0.39, respectively; p < 0.01). CONCLUSION In our study, after the initiation of keto/amino acid treatment, PON-1, which is a significant antioxidant marker, and ARE plasma activities increased and tissue destruction product MDA and sialic acid significantly decreased. In the light of all these data, we think that this treatment can reduce OS, improve hypoalbuminemia, which causes both mortality and morbidity in patients, improve survival in PD patients, and may be an antioxidant treatment in suitable patients.

Abstract
Peritonitis is a common clinical problem in patients treated by continuous ambulatory peritoneal dialysis (CAPD). The most common microbiological factors causing peritonitis are Gram-positive (especially Staphylococcus spp.). Peritonitis with Rhizobium radiobacter (Agrobacterium radiobacter) is a rare infection in CAPD patients. Peritonitis due to R. radiobacter has been reported in our patient's dialysate culture who underwent CAPD for three years. We report the case of a 26-year-old female PD patient who had CAPD peritonitis due to R. radiobacter and successfully treated with intraperitoneal vancomycin and oral ciprofloxacin without relapses or removing the PD catheter.

Abstract
Background Different non-invasive imaging techniques such as Doppler ultrasonography and renal scintigraphy are commonly employed to assess allograft function and associated complications. However, all such methods lack sufficient specificity to discriminate between residual renal function of native kidneys. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) evaluates signal dynamics during the passage of contrast material through the renal cortex, medulla, and collecting system. Purpose To investigate the value of DCE 3T MRI using a quantitative pharmacokinetic parameter (Ktrans) for the assessment of native kidneys before and after pre-emptive renal transplantation. Material and Methods Twenty-five consecutive patients with end-stage renal disease underwent DCE MRI before and 6 months after kidney transplantation. MRI was performed using a 3T scanner. Regions of interests were drawn over each kidney, encompassing the cortex and medulla but excluding the collecting system and any coexisting cysts. Parametric Ktrans values were automatically generated. Results In the pre-transplantation group, mean Ktrans values for the right and left kidneys were 0.55 ± 0.09 min-1 and 0.44 ± 0.15 min-1, respectively. In the post-transplantation group, mean Ktrans values of the right and left kidneys were 0.27 ± 0.07 min-1 and 0.25 ± 0.10 min-1, respectively. There were statistically significant differences between right and left kidneys in terms of mean Ktrans values in the pre- and post-transplantation groups ( P < 0.001). Conclusion Our preliminary results show that native kidneys were still functioning 6 months after transplantation. MR perfusion using Ktrans may constitute a non-invasive means of determination of the viability of native kidneys after renal transplantation.

Abstract
AIM Cardiovascular diseases and infections are the leading two causes of morbidity and mortality in end-stage renal disease (ESRD) patients. Kidney transplantation is the preferred method for renal replacement owing to better survival. There are reports of irreversibly damaged immune system in dialysis patients, which did not return to normal even after kidney transplantation. The neutrophil-lymphocyte ratio (NLR) is an easily applicable method for evaluation of inflammation. We hypothesized that preemptive kidney transplantation can improve inflammatory state compared with nonpreemptive recipients. To test our hypothesis, we retrospectively investigated pretransplant and posttransplant NLR and C-reactive protein (CRP) levels of ESRD patients and compared them with values in healthy controls. MATERIALS AND METHODS We retrospectively analyzed NLR, CRP, and other hematologic parameters of ESRD patients who were transplanted between January 2005 and January 2014 on the day of transplantation and at the end of first year. We grouped the patients as preemptive and nonpreemptive ones. We excluded patients with coronary artery disease, obesity, hypotension, hyperthyroidism, uncontrolled diabetes mellitus, hematologic or solid organ cancers, and active documented infection at any evaluation period. RESULTS We included 137 ESRD patient and 34 healthy control individual in our study. Of the 137 ESRD patients, 52 (38%) were transplanted preemptively. Of the patients, 85 were already on either hemodialysis or peritoneal dialysis therapy at the time of transplantation. The white blood cell count value of the patient and control group (7246.72 ± 1460.26 and 76661.76 ± 1286.29, respectively; P = .43), NLR of the control group was significantly lower than patient group (1.98 ± 0.94 and 3.47 ± 2.33, respectively; P = .007). The NLR of the preemptive group was decreased substantially at the end of first year posttransplantation, the NLR of the preemptive group was significantly lower than the nonpreemptive group (3.08 ± 1.32 and 3.71 ± 2.33; P = .01). CONCLUSIONS We showed that all ESRD patients had an increased inflammation rate according to CRP and NLR when compared with healthy controls. We also found that improvement of inflammatory state in preemptive patients is significantly better than nonpreemptive patients at the end of first year evaluation.

Abstract
Cytosine arabinoside (Ara-C) is one of the critical agents for the treatment of acute myeloid leukemia (AML). The toxicity profile of Ara-C is highly dependent on the dose and schedule of administration. Cardiologic complications associated with Ara-C are rare. These side effects were reported with high doses of cytarabine (1-3 g/m2, 6-12 doses) in the literature. Herein, we report a patient who developed symptomatic sinus bradycardia while receiving low-dose Ara-C therapy for AML. A 45-year-old female patient diagnosed with AML was treated with standard remission induction chemotherapy protocol that includes 3 days of anthracycline and 7 days of low-dose (100-200 mg/m2 2-1) Ara-C. The same chemotherapy regimen was applied again on the 15th day of admission. During the second chemotherapy cycle, the patient developed symptomatic sinus bradycardia. All causes except Ara-C were excluded after required investigational procedures. Ara-C infusion was discontinued for a while and after her symptoms passed chemotherapy was completed with atropine support. Cardiac toxicity is scarce with Ara-C. We want to remind that clinicians should be aware of this potential toxic manifestation even in low doses of the medication, especially as Ara-C is widely used in the treatment of leukemia. <Learning objective: Cytosine arabinoside is one of the historic chemotherapeutics in hematology. It was widely used to treat many types of hematological malignancies in high doses and is commonly available in worldwide markets. Symptomatic sinus bradycardia is a rare type of cardiologic side effect, but it should be kept in mind during chemotherapy.>.
