Abstract

ObjectiveTo better define the prevalence of protein-energy wasting (PEW) in kidney disease is poorly defined.MethodsWe performed a meta-analysis of PEW prevalence from contemporary studies including more than 50 subjects with kidney disease, published during 2000-2014 and reporting on PEW prevalence by subjective global assessment or malnutrition-inflammation score. Data were reviewed throughout different strata: (1) acute kidney injury (AKI), (2) pediatric chronic kidney disease (CKD), (3) nondialyzed CKD 3-5, (4) maintenance dialysis, and (5) subjects undergoing kidney transplantation (Tx). Sample size, period of publication, reporting quality, methods, dialysis technique, country, geographical region, and gross national income were a priori considered factors influencing between-study variability.ResultsTwo studies including 189 AKI patients reported a PEW prevalence of 60% and 82%. Five studies including 1776 patients with CKD stages 3-5 reported PEW prevalence ranging from 11% to 54%. Finally, 90 studies from 34 countries including 16,434 patients on maintenance dialysis were identified. The 25th-75th percentiles range in PEW prevalence among dialysis studies was 28-54%. Large variation in PEW prevalence across studies remained even when accounting for moderators. Mixed-effects meta-regression identified geographical region as the only significant moderator explaining 23% of the observed data heterogeneity. Finally, two studies including 1067 Tx patients reported a PEW prevalence of 28% and 52%, and no studies recruiting pediatric CKD patients were identified.ConclusionBy providing evidence-based ranges of PEW prevalence, we conclude that PEW is a common phenomenon across the spectrum of AKI and CKD. This, together with the well-documented impact of PEW on patient outcomes, justifies the need for increased medical attention.

Abstract

This advisory committee convened to review national and global kidney transplantation dynamics and provide recommendations on the use of anti-T lymphocyte globulin (ATLG) for prevention and treatment of rejection afer allogeneic kidney transplantation. A critical evaluation of 6 relevant articles released up to October 2022 was performed to reveal their importance in clinical practice. Additionally, 27 key questions on the indication, dosage of ATLG, and risk stratifcation were used for the Delphi technique with 8 members of the Turkish Society of Nephrology including 5 kidney transplantation (KTx) subcommittee members and a surgeon experienced in solid organ transplantation. The committee declared that Türkiye had great potential in KTx; however, increase in transplantation would be possible in the case of raise in the deceased donor transplantation. As a consensus, ATLG was strongly recommended for induction and rejection treatment. Also, committee members recommended the safe dosage range in steroid resistant acute rejection as 2.5-3 mg/kg daily for 5-7 days, and the median of preferred dosage in induction sounded as 2-2.5 mg/kg daily for 3 days in intermediate risk state. Additionally, post-transplant infection and malignancy cases due to immunosuppression were much rarely encountered than they were in the past. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Vascular calcification is an intervenable factor in the pathophysiology of cardiovascular disease. Treatment‐related factors might worsen the arterial stiffness in chronic hemodialysis patients. The aim of the study is to compare the effects of 1‐year treatment with paricalcitol or calcitriol on pulse wave velocity (PWV), which is an indicator of arterial stiffness and osteocalcin and fetuin‐A levels. Methods: Seventy‐six hemodialysis patients who had similar PWV1 at the beginning were evaluated after a 1‐year treatment of paricalcitol or calcitriol. PWV2, serum osteocalcin, and fetuin‐A levels were measured at the end of the study. Results: At the end of the study, PWV2 of paricalcitol group was statistically lower than the calcitriol group. Osteocalcin levels were statistically lower and fetuin‐A levels were statistically higher in the paricalcitol group than the calcitriol group at the end of the study. The number of patients with PWV2 > 7 m/s and using paricalcitol was 16 (39%) but 25 (41%) patients were using calcitriol; the differences were statistically significant. Conclusions: The long‐term benefits of paricalcitol were superior to the benefits of calcitriol. Paricalcitol has protective effects from vascular calcification in chronic hemodialysis patients.

Abstract

© 2022 Turkish Society of Nephrology. All rights reserved.Objectives: There is limited data about coronavirus disease-19 (COVID-19) characteristics and results in peritoneal dialysis (PD) patients. This study aimed to investigate the characteristics and outcomes among PD patients and compare them with matched hemodialysis (HD) patients and a control group without kidney disease. Methods: We included 18 PD patients and consecutive age- and gender-matched 18 HD and 18 patients without kidney disease (control group) registered into the Turkish Society of Nephrology database including 1301 COVID-19 patients. We compared demographic, clinical, radiological, laboratory data, and outcomes namely intensive care unit (ICU) admission, mechanical ventilation, mortality, and composite outcome (death and/or ICU admission). Results: ICU admission, mechanical ventilation, and mortality rates in PD patients (27.8%, 22.2%, and 22.2%, respectively) and the HD group (16.7%, 11.1%, and 16.7%, respectively) were higher than the control group (11.1%, 11.1%, and 5.6%, respectively), but intergroup comparison did not reveal difference. A total of 11 (20.3%) patients had composite outcome (6 PD patients, 3 HD patients, and 2 patients in the control group). In Cox regression analysis, higher age and higher CRP level were related to increased risk of composite outcome. Adjusted rate of composite outcome in PD group was significantly higher than the control group (P = .050). This rate was similar in HD and control groups (P = .30). Conclusions: Combined in-hospital mortality and/or ICU admission of PD patients with COVID-19 was significantly higher than the control patients. There is a need for careful surveillance of PD patients for infection signs and prompt treatment of COVID-19.

Abstract

Objective: Variations in care at national or global level may have an impact on the prognosis of patients on chronic hemodialysis. We aimed to describe regional differences in all-cause mortality or cardiovascular morbidity in chronic hemodialysis patients in Turkey. Methods: We enrolled 2461 patients who were initiated chronic hemodialysis in 93 centers in Turkey between January 27, 2017, and February 09, 2018. We included 2-year follow-up data of 1877 patients in this prospective study. The primary outcome, the rate of composite endpoint of all-cause mortality or cardiovascular morbidity, was compared between geographical regions. Secondary outcomes were the rates of hospitalization and infections. Results: In total, 552 patients (29.4%) developed the primary outcome. The highest and lowest rates of primary outcome occurred in the Mediterranean (34.5%) and Southeastern (26.5%) & Central Anatolian regions (26.5%), respectively, with no significant differences across regions (P = .82). Hospitalization events were detected in 377 patients (20.1%). The highest rate of hospitalization was detected in the Black Sea region (33.8%), and the lowest (7.6%) in the Southeastern region. The regions did not differ in hospitalization rates (P = .88). Infections occurred in 11.3% (n = 212) of the patients. The highest and lowest rates of infections occurred in the Aegean (18.2%) and the Southeastern (2.9%) regions, respectively. We detected significant difference between geographic regions (P = .02). Conclusions: Our study showed that almost 3 in every 10 chronic hemodialysis patients reached the primary endpoint of all-cause mortality/cardiovascular morbidity during the 2 years of follow-up. The occurrence of this outcome does not seem to exhibit geographical variation across the country.

Abstract

Tuberculosis (TB) remains a common problem in patients with chronic renal failure. In intensive care units, misdiagnosis or delayed diagnosis of TB is common. Therefore, a description of characteristics of active TB in patients with renal failure followed in intensive care units is important to reduce mortality and transmission of the disease. This study was performed to describe the characteristics of patients with renal failure admitted to the intensive care units and having active TB and evaluate predictive factors for in hospital mortality. The hospital records of 24 patients (11 women, 13 men) having ESRD and TB between 2001-2006 were reviewed. Clinical, radiological, and laboratory data on admission were recorded. Possible parameters contributing to in-hospital mortality were obtained from the medical records. In-hospital mortality rate was 66.6%. Factors associated with mortality were decreased partial pressure of oxygen and malnutrition. Fever was reported in 8 patients and hemoptysis was reported in 3 patients. Eight patients had consolidation on chest radiograph, while 4 had normal findings Seventeen patients had pulmonary involvement, and 11 had extra pulmonary involvement. The mortality rate in TB patients followed in intensive care units is high, with 3 factors contributing to in-hospital mortality. Clinicians should consider active TB in renal failure patients being followed in the intensive care unit, even when results of a chest radiograph are normal especially in patients with unexplained poor general health or respiratory failure.

Abstract

Background: we aimed to present the demographic characteristics, clinical presentation, and outcomes of our multicenter cohort of adult KTx recipients with COVID-19.Methods: we conducted a multicenter, retrospective study using data of patients hospitalized for COVID-19 collected from 34 centers in Turkey. Demographic characteristics, clinical findings, laboratory parameters (hemogram, CRP, AST, ALT, LDH, and ferritin) at admission and follow-up, and treatment strategies were reviewed. Predictors of poor clinical outcomes were analyzed. The primary outcomes were in-hospital mortality and the need for ICU admission. The secondary outcome was composite in-hospital mortality and/or ICU admission.Results: one hundred nine patients (male/female: 63/46, mean age: 48.412.4years) were included in the study. Acute kidney injury (AKI) developed in 46 (42.2%) patients, and 4 (3.7%) of the patients required renal replacement therapy (RRT). A total of 22 (20.2%) patients were admitted in the ICU, and 19 (17.4%) patients required invasive mechanical ventilation. 14 (12.8%) of the patients died. Patients who were admitted in the ICU were significantly older (age over 60 years) (38.1% vs 14.9%, p=0.016). 23 (21.1%) patients reached to composite outcome and these patients were significantly older (age over 60years) (39.1% vs. 13.9%; p=0.004), and had lower serum albumin (3.4g/dl [2.9-3.8] vs. 3.8g/dl [3.5-4.1], p=0.002), higher serum ferritin (679 mu g/L [184-2260] vs. 331 mu g/L [128-839], p=0.048), and lower lymphocyte counts (700/mu l [460-950] vs. 860 /mu l [545-1385], p=0.018). Multivariable analysis identified presence of ischemic heart disease and initial serum creatinine levels as independent risk factors for mortality, whereas age over 60 years and initial serum creatinine levels were independently associated with ICU admission. On analysis for predicting secondary outcome, age above 60 and initial lymphocyte count were found to be independent variables in multivariable ana, NA
