RESUMO
INTRODUCTION: There are many differences between hemodialysis (HD) and peritoneal dialysis (PD) treatments, including their impact on the psychological status of the patients. In this study, our aim was to compare the psychological statuses of HD and PD patients during the social isolation period due to the COVID-19 pandemic. METHODS: We conducted this cross-sectional study on adult HD and PD patients when the curfew measures were in effect. We used an electronic form composed of 3 sections to collect data. In the first section, we collected data on the demographics and clinical and laboratory parameters of the patients. The second and third sections consisted of the Hospital Anxiety and Depression Scale (HADS) and the Impact of Event Scale-Revised (IES-R) questionnaires, respectively. RESULTS: The HD (n = 116) and PD (n = 130) groups were similar regarding age and sex, and they had similar HADS anxiety scores. HADS depression scores were higher in PD patients (p = 0.052). IES-R scores were significantly higher in PD patients in comparison to HD patients (p = 0.001). Frequencies of abnormal HADS-anxiety (p = 0.035) and severe psychological impact (p = 0.001) were significantly higher in PD patients. DISCUSSION/CONCLUSION: During the social isolation period due to the COVID-19 pandemic, HD patients had better mood profiles than PD patients. A more stable daily routine, an uninterrupted face-to-face contact with health-care workers, and social support among patients in the in-center dialysis environment might be the cause of the favorable mood status. PD patients might need additional psychological support during those periods.

BACKGROUND: To evaluate osteoprotegerin (OPG) levels in relation to cardiovascular (CV) risk factors in patients with chronic kidney disease (CKD) on different regimens of renal replacement therapy. METHODS: A total of 143 patients with CKD and 30 healthy controls were included in this study and divided into five categories, including predialysis patients with chronic renal failure (preD; n = 36), chronic peritoneal dialysis patients (PD; n = 36), hemodialysis patients (HD; n = 35), renal transplant patients (RT; n = 36), and controls (n = 30). Data on demographics, concomitant diseases and CV risk factors, serum OPG levels, and correlates of serum OPG levels were determined. RESULTS: Serum OPG (pmol/l) levels were significantly higher in HD (P <0.001 for each), PD (P <0.001 for each), and preD (P <0.01 vs. control, P <0.05 vs. RT) groups than RT and control groups. Diabetics than nondiabetics in HD (P = 0.008), PD (P = 0.024), and RT (P = 0.004) groups and males than females in PD group (P = 0.021) had higher OPG levels. Serum OPG levels were associated positively with age in HD (P <0.001), PD (P = 0.001), and in overall population (P <0.001). CONCLUSION: Our findings revealed increased serum levels of OPG in dialysis and preD patients compared to RT and controls. In the patient groups receiving two dialysis treatment, the levels were worse, indicating a more pronounced vascular injury. Age, C-reactive protein (CRP), high-density lipoprotein cholesterol (HDL-C), and cystatin C (CysC) in CKD patients, CRP and PTH in the control subjects, and age and BMI in the overall population were the significant correlates of serum OPG levels.

BACKGROUND: Hyponatremia is classified according to volume status with the help of physical examination, biochemical measures, urine and serum osmolalities, and echocardiography. Bioimpedance spectroscopy (BIS) has been getting popularity for revealing tissue compositions of various patient groups. The aim of this observational study was to investigate the role of BIS for the differential diagnosis of hyponatremia (ClinicalTrials.gov Identifier: NCT01838759). PATIENTS AND METHODS: Personal characteristics of age, sex, weight, height, and blood pressure were recorded. Body composition monitor (BCM) was used for hydration status for each individual. Primary outcome was investigated by the accuracy of volume status measured by BIS. STATISTICS: Kappa statistic (K) is a measure of agreement between two sources, which is measured on a binary scale (i.e., condition present/absent). K statistic can take values between 0 and 1: poor agreement: K < 0.20, fair agreement: 0.2.0-0.3.9, moderate agreement: 0.40-0.59, substantial: 0.60-0.79, very good agreement: 0.80-1.00. RESULTS: Fifty-eight hyponatremia-diagnosed patients, 32 (55.2%) of male with the mean age of 65.2 ± 11 (40-89) years were included. Kappa statistic (K) were very good (K = 0.925) for male (p < 0.00), substantial agreement (K = 0.601) for female (p < 0.002) with the use of BIS for the differential diagnosis of either hypo or hypervolemia in hyponatremic patients compared with gold standard tests which were the combination of echocardiography, serum, and urine osmolality biochemical tests, and physical examination. CONCLUSION: Bioimpedance spectroscopy is a practical and an inexpensive method. This is the first study in the literature showing the role of BIS for the determination of the volume status and differential diagnosis of hyponatremia when compared with echocardiography.

AIM: The present study aims to establish the role of serum CGRP and SP levels in the disease pathophysiology in patients with dialysis headache not accompanied by primary or secondary headaches, and also whether there is a correlation between these vasoactive peptides and the severity of headache. METHOD: This study was designed as prospective and multicenter. A total of 30 dialysis headache patients and 30 patients without headache as the control group in the Nephrology outpatient clinics which implement similar dialysis procedures were included in the study. Blood samples were taken from all the patients before hemodialysis, and post-hemodialysis samples were collected. CGRP and SP contents in serum samples were measured using the ELISA method with detection kits. RESULTS: A total of 60 patients were included in the study with 17 female and 13 male patients in the dialysis headache group and 18 female and 12 male patients in the control group, and there were no significant differences in sex and age between the groups. CGRP levels in the headache group were found to be significantly higher compared with the control group both before and after hemodialysis. Furthermore, pre-hemodialysis CGRP levels were significantly higher than post-hemodialysis CGRP levels in both the headache and control groups. Serum SP levels in the headache group were found to be higher compared with the control group both before and after hemodialysis, there was no significant difference between the groups. Even though SP levels in both groups decreased after hemodialysis, there was again no significant difference between the groups. No correlation was found between the patients' severity of headache and serum CGRP and SP levels. CONCLUSION: This study concludes that CGRP and SP, even though the latter is not statistically significant, play a role in the pathophysiology of the dialysis headache, and further studies with a larger and more specific patient population may reveal the relationship between the neuropeptides and dialysis headache more clearly.

INTRODUCTION: Overhydration is the main contributory factor of left ventricular hypertrophy and closely associated with cardiovascular events in end stage renal disease (ESRD) patients. The aim of this prospective-study was to investigate the impact of strict salt and volume control on hypertension and cardiac condition in ESRD patients. METHODS: A total of 12 peritoneal dialysis (PD) and 15 prevalent hemodialysis (HD) patients were enrolled. All patients either PD or HD were allocated to intervention of strict salt restriction according to basal hydration state of empty abdomen in PD and midweek predialysis HD which were estimated by body composition monitor (BCM) and echocardiography. RESULTS: Mean ages were 48.3 ± 16.7 years for PD, and 48.8 ± 18 for HD patients. Extracellular water/height was 10.04 ± 2.70 and 10.39 ± 1.53 L/m in PD and HD groups. Systolic blood pressures decreased in PD and HD from 133.1 ± 28 and 147.3 ± 28.5 to 114.8 ± 16.5 and 119.3 ± 12.1 mmHg, respectively, (p < 0.00). IDKA/DW were decreased from 3.26 ± 1.6 to 2.97 ± 1.63 % in HD group (p > 0.05). LVMI and LAI were not increased in both groups. CONCLUSION: Strict salt and volume control in ESRD patients after assessment of hydration status with either using BCM or echocardiography provides better management of volume control leading to more precise cardiovascular protection.

This study evaluated the effectiveness of prognostic nutritional index (PNI) in predicting contrast induced nephropathy (CIN) in patients with acute coronary syndrome (ACS). This study included 925 ACS patients (mean age 62.5 ± 12.4 years, 73.5% male); 604 were diagnosed as unstable angina pectoris/non-ST-elevation myocardial infarction (USAP/NSTEMI) and 321 as ST-elevation myocardial infarction (STEMI). The PNI formula was: 10 × serum albumin (g/dL) + .005 × total lymphocyte count (/mm3). The patients were divided into two groups: CIN (n = 232) and non-CIN (n = 693). Patients without CIN had a significantly lower PNI than patients with CIN (44.3 ± 6.9 vs 54.7 ± 7.4; P < .001). In the receiver operating characteristic (ROC) curve analysis, the cut-off value for PNI of 48.6 has 80% specificity and 81% sensitivity in predicting CIN (area under the ROC curve (AUC): .87, 95% CI [.84-.89]). PNI <48.6 (odds ratio (OR): 6.765, P < .001), pre-procedural creatinine levels (OR: 6.223, P < .001), left ventricular ejection fraction (LVEF) (OR: .960, P < .001), age (OR: 1.025, P = .005), diabetes mellitus (DM) (0R: 1.768, P = .006), contrast amount (OR: 1.003, P = .038), and having STEMI (OR: .594, P = .029) were found independently associated with CIN. PNI is a strong independent predictor of CIN in ACS patients.

Prognostic information is important for the management of acute coronary syndrome (ACS). Our aim was to evaluate Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score-II (SSII) for predicting contrast induced nephropathy (CIN) and one-year major adverse cardiac events (MACE) in ACS patients. Coronary angiographic recordings of 1304 ACS patients were retrospectively examined. Predictive values of SYNTAX score (SS), SSII-percutaneous coronary intervention (SSII-PCI), SSII-coronary artery bypass graft (SSII-CABG) scores for CIN and MACE were assessed. Combination of CIN and MACE ratios constituted primary composite end-point. Patients with SSII-PCI scores >32.55 were compared with patients with lower scores. All of the three scoring systems predicted the composite primary end-point [SS: Area under the curve (AUC): .718, P < .001 (95% CI: .689-.747), SSII-PCI: AUC: .824, P < .001 (95% CI: .800-.849), SSII-CABG: AUC: .778, P < .001 (95% CI: .751-.805)]. Comparison of AUC of receiver operating characteristic curves showed that SSII-PCI score had better predictive value than that of SS and SSII-CABG scores. In multivariate analysis, the only predictor of the primary composite end-point was SSII-PCI score (odds ratio: 1.126, 95% CI: 1.107-1.146, P < .001). SSII-PCI score was a valuable tool for prediction of shock, CABG, myocardial infarction, stent thrombosis, development of CIN and one-year mortality.
RESUMO
PURPOSE: Abnormalities of trace elements have previously been linked to inflammatory processes in hemodialysis (HD) patients. We aimed to establish the trace element status of maintenance HD patients, to investigate the relationship between coronary artery calcification scores (CACs) and whole blood levels of trace elements. METHODS: Patients undergoing HD in three times a week for > 6 months and age-and sex-matched controls were included from October 2015 to June 2016. Data were collected from patient files. All subjects' whole blood levels of trace elements were measured by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). CACs for patients were assessed by multi-detector computed tomography. RESULTS: The 35 patients (male, 60%) with a mean age of 45.7 ± 10.4 years and 35 controls were included. HD patients showed significantly lower levels of selenium and uranium and higher cadmium (Cd), cobalt, lithium, manganese, nickel, lead, platinum, tin, strontium, and thallium levels compared to controls. Coronary artery calcification (CAC) was present in 21 patients (60%), and median CACs were 14.2 (IQR 0-149). Patients with CACs > median were significantly older, had a higher prevalence of hypertension and lower ALP levels than patients with CACs ≤ median. No significant differences in whole blood levels of trace elements were found between patients with CACs > median and patients with CACs ≤ median. A near significance was noted in median whole blood levels of Cd between these groups (P = 0.096). According to multivariate analysis, age was the only independent determinant for CAC development. CONCLUSION: Age is independently associated with coronary vascular calcification. High Cd levels might play a role in CAC development in HD patients.

BACKGROUND: Contrast induced nephropathy (CIN) is one of the feared complications of contrast medium-using procedures. Present study was conducted in order to evaluate the value of systemic inflammatory-response index (SIRI) for development of CIN among patients who underwent primary percutaneous intervention. METHODS: Six hundred seventy-six patients with the diagnosis of ST elevation myocardial infarction were included. The patients were divided into two groups according to the presence of CIN. Patients without (n = 530) and with (n = 146) CIN constituted group 0 and group 1, respectively. Clinical and biochemical features of the patients were recorded. Calculation of SIRI was made for each patient. RESULT: CIN patients were older, had higher prevalence of hyperlipidaemia, higher values of pre- and post-procedural creatinine levels, neutrophil and monocyte counts, neutrophil/lymphocyte ratio (NLR) and monocyte/lymphocyte ratio (MLR) and SIRI. They had lower values of left ventricular ejection fraction (LVEF), haemoglobin and high-density lipoprotein-cholesterol levels. SIRI had the highest area under the curve (AUC) for prediction of CIN. Pairwise analyses of the AUC's demonstrated that SIRI had statistically significantly higher AUC compared to NLR and MLR. Multivariate logistic regression analysis showed that besides from LVEF and pre-procedural creatinine, NLR and SIRI were the independent predictors of CIN. SIRI had a higher odds ratio compared to NLR. CONCLUSION: SIRI had greater diagnostic power than NLR and MLR and it can easily be used by physicians for the identification of high-risk patients for the occurrence of CIN.

The aim of the study was to evaluate the clinical features of the patients on HD with COVID-19 and determine the prognostic factors. In this single-center prospective study, a total of 58 chronic renal failure patients on HD and diagnosed COVID-19 infection were enrolled in the study. The patients were divided into two groups according to their need for intensive care unit referral. Demographic features of the patients, clinical manifestations, laboratory data, treatments, and clinical outcome were evaluated. The mean age of 58 HD patients was 63.2 ± 13.8 (30-93) years and female-male ratio was 0.34. SARS-CoV2-PCR positivity rate was 32.8%. 85.2% of patients (n = 46) had bilateral lesions and 14.8% (n = 8) had unilateral one lesion in chest CT. The most common symptoms were fatigue (in 44 patients, 80%) and dyspnea (in 31 patients, 56.4%). The most common comorbidity was HT (in 37 patients, 67.3%). The patients who need intensive care and died were older (p = 0.015). We observed lower platelet and eosinophil counts, potassium levels, higher AST, troponin and CRP levels in the group of patients who need intensive care and died than the group who survived (p = 0.043, 0.005, 0.033, 0.007, 0.001, <0.001, respectively). 15.5% of the patients (n = 9) were transferred to intensive care unit. Among them, two were discharged with cure and seven patients died. Mortality rate was 12.1%. Older age, lower platelet and eosinophil counts and higher AST, troponin and CRP levels were prognostic risk factors in our HD patients who needed intensive care.

OBJECTIVES: Hypertension and hypervolemia relationship was proven among renal disease, although it is not known in normal population. Present study determines the fluid distribution defects in relation to blood pressure. MATERIAL AND METHODS: In a population-based survey in Turkey demographics, height, weight, blood pressure, urine analysis, and serum creatinine measurements were recorded. Bioimpedance measured with the Body Composition Monitor. RESULTS: Total 2034 population of 71.6% male, mean age 47 ± 12.6 (18-89) years, systolic blood pressure (SBP) 134.7 ± 20, diastolic blood pressure 77.9 ± 11.6 mmHg. Body mass index (BMI) was 28.5 ± 4.5 (15.8-50.6) kg/m(2); overhydration was 0.05 ± 1.05 L. There was a correlation between extracellular water (ECW)/height and SBP (r = 0.21, P < 0.001). Receiver operating characteristic (ROC) curve with the performance of 0.60 (P < 0.001) that showed cut-off value of ECW/height was 10.06 L/m, with the 69% sensitivity and 45% specificity for SBP: 140 mmHg values. Risk factors for high SBP were increase of ECW/Height, age, BMI and presence of diabetes. ECW/height, SBP, and fat tissue index (FTI) increased in BMI categories (low, normal, and obese) and in diabetics. SBP and FTI were lower in smokers. CONCLUSIONS: High blood pressure may be accompanied by increased extracellular volume indices. In the future volume status assessment could be of use in evaluating the effectiveness of pharmacological intervention in the treatment of hypertension.

Introduction. Continuous ambulatory peritoneal dialysis (CAPD) is widely accepted for the management of end-stage renal disease (ESRD). Although not as widely used as hemodialysis, CAPD has clear advantages, especially those related to patient satisfaction and simplicity. Peritoneal dialysis (PD) catheter insertion can be accomplished by several different techniques. In this study, we aimed to evaluate our results obtained with peritoneal dialysis catheter placement by combination of pelvic fixation plus preperitoneal tunneling. Material and Methods. Laparoscopic peritoneal catheter implantation by combining preperitoneal tunneling and pelvic fixation methods was performed in 82 consecutive patients with end-stage renal disease. Sex, age, primary disease etiology, complications, mean duration of surgery, mean duration of hospital stay, morbidity, mortality, and catheter survival rates and surgical technique used were assessed. Analysis of catheter survival was performed using the Kaplan-Meier method. Results. Mean follow-up period was 28.35 ± 14.5 months (range of 13-44 months). Mean operative time was 28 ± 6 minutes, and mean duration of hospital stay was 3 ± 1 days. There were no conversions from laparoscopy to other insertion methods. None of the patients developed serious complications during surgery or the postoperative period. No infections of the exit site or subcutaneous tunnel, hemorrhagic complications, abdominal wall hernias, or extrusion of the superficial catheter cuff was detected. No mortality occurred in this series of patients. Catheter survival was found to be 92% at 3 years followup. Conclusions. During one-year followup, we had seven patients of migrated catheters due to separation of pelvic fixation suture from peritoneal surface, but they were reimplanted and fixated again laparoscopically with success. Over a three-year followup period, catheter survival was found to be 92%. In the literature, similar catheter survival rates without combination of the two techniques are reported. As a conclusion, although laparoscopic placement of PD catheters avoids many perioperative and early complications, as well as increasing catheter free survival period and quality of life, our results comparing to other studies in the literature indicate that different laparoscopic placement methods are still in debate, and further studies are necessary to make a more accurate decision.
