BACKGROUND: The chronic use of angiotensin-converting enzyme inhibitors or angiotensin II receptor blocker has been associated with hyperkalemia in patients with reduced renal function even after the initiation of hemodialysis. Whether such medications may cause a similar effect in peritoneal dialysis patients is not well established. So, the aim of our study was to analyze the impact of renin-angiotensin-aldosterone inhibitors on the serum levels of potassium in a national cohort of peritoneal dialysis patients...

Acute kidney injury in the intensive care unit (ICU) is a manifestation of an underlying severe illness that commonly involves other organ systems. Pulmonary, cardiac, and hepatic failures are the most prevalent. This article provides a simplified review of the technical aspects of extracorporeal cardiopulmonary and liver support devices used in the adult ICU patient, as well as a summary of the most relevant and up-to-date clinical evidence that supports their use.

BACKGROUND: Inflammation plays a crucial role in renal interstitial fibrosis, the pathway of chronic kidney diseases. Necroptosis is a novel form of regulated cell death, which plays a potential role in inflammation and renal diseases. The small molecule necrostatin-1 (Nec-1) is a specific inhibitor of necroptosis. This study was aimed at determining the role of necroptosis, RIP1/RIP3/mixed lineage kinase domain-like (MLKL) signaling pathway, in renal inflammation and interstitial fibrosis related to primitive tubulointerstitial injury...

BACKGROUND: We hypothesized that in the very elderly dialysis patients in the United States, institutionalization in nursing homes would increase mortality in addition to age alone. METHODS: Incident dialysis patients from 2001 to 2008 above the age of 70 were included. Patients above 70 were categorized into 4 groups according to age as 70-75, 76-80, 81-85, and >85 years and further divided into institutionalized and noninstitutionalized. Kaplan-Meier survival curves were plotted to assess patient survival...

BACKGROUND: Higher serum ferritin levels may be influenced by iron use and inflammation, and are associated with higher mortality in hemodialysis (HD) patients. We hypothesized that a major rise in serum ferritin is associated with a higher risk of mortality, irrespective of baseline serum ferritin in incident HD patients. METHODS: In a cohort of 93,979 incident HD patients between 2007 and 2011, we examined the association of change in serum ferritin from the baseline patient quarter (first 91 days from dialysis start) to the subsequent quarter with mortality...

BACKGROUND: C3 glomerulopathy (C3GP) is a recently identified and described disease that has a high risk of progressing into end-stage renal disease. We aimed to evaluate the effects of various immunosuppressive regimens on C3GP progression because there are conflicting data on the treatment modalities. METHODS: In this retrospective study of 66 patients with C3GP, 27 patients received mycophenolate mofetil (MMF)-based treatment, 23 received non-MMF-based treatment (prednisolone or cyclophosphamide), and 16 received conservative care...

BACKGROUND: A beneficial effect of rituximab (RTX) on focal segmental glomerulosclerosis (FSGS) in pediatric patients or in transplant recipients has been reported in isolated cases. However, the use of RTX in adult patients with idiopathic FSGS needs further investigation. METHODS: Eight patients who had biopsy-proven FSGS (63.9 ± 14.0, range 40-81 years, 4 women, 4 men) with major risk factors precluding corticosteroids or conventional immunosuppression were treated with a high dose of RTX (8 weekly doses of 375 mg/m2) and prospectively followed up for at least 2 years (29...

BACKGROUND: Little information is available regarding the type of dialyzer which results in good prognosis. This study is aimed at investigating the association between 7 types of dialyzers and 2-year mortality. METHODS: We conducted a cohort study using data from a nationwide registry of the Japanese Society for Dialysis Therapy. Subjects were 136,676 patients on maintenance hemodialysis (HD) between 2009 and 2011 who underwent maintenance HD for at least 2 years and were treated with one of the following 7 types of high-performance membrane dialyzers: cellulose triacetate (CTA), ethylene vinyl alcohol (EVAL), polyacrylonitrile (PAN), polyester polymer alloy (PEPA), polyethersulfone (PES), polymethylmethacrylate (PMMA), and polysulfone (PS)...

BACKGROUND: The role of myeloperoxidase in chronic kidney disease (CKD) and its association with coronary artery disease (CAD) is controversial. In this study, we compared myeloperoxidase and protein-bound 3-chlorotyrosine (ClY) levels in subjects with varying degrees of CKD and tested their associations with CAD. METHODS: From Clinical Phenotyping Resource and Biobank Core, 111 patients were selected from CKD stages 1 to 5. Plasma myeloperoxidase level was measured using enzyme-linked-immunosorbent assay...

BACKGROUND: Recent data suggest that there is a pathogenic role for CXC ligand 16 (CXCL16) in cardiovascular diseases. Little is known about circulating CXCL16 in patients with kidney dysfunction. We explored the relationships of plasma CXCL16 with cardiac injury markers in a group of dialysis patients. METHODS: Plasma CXCL16 and C-reactive protein (CRP) were measured in 366 patients who were on maintenance hemodialysis. Cardiac injury was evaluated via measurements of the circulating B-type natriuretic peptide (BNP), N-terminal prohormone of brain natriuretic peptide (NT proBNP), Troponin I (TnI), and Troponin T (TnT)...

BACKGROUND: Volume overload is frequent in diabetics undergoing peritoneal dialysis (PD), and may play a significant role in the excess mortality observed in these patients. The characteristics of peritoneal water transport in this population have not been studied sufficiently. METHOD: Following a prospective, single-center design we made cross-sectional and longitudinal comparisons of peritoneal water transport in 2 relatively large samples of diabetic and nondiabetic PD patients...

BACKGROUND: Few genetic studies have focused on unilateral renal agenesis (URA), which is a disorder with insidious clinical manifestations and a tendency to result in renal failure. We aimed to detect pathogenic mutations in nephrogenesis-related genes, which were identified by a literature review conducted among a large cohort of Chinese Han patients with URA. METHODS: Totally, 86 unrelated URA patients were included. All URA patients were diagnosed by employing radiological methods...

BACKGROUND: Arterial calcification (AC) is frequent in patients with end stage renal disease and is also considered a risk factor for later morbidity and mortality. However, long-term factors associated with the process are not well known. We analyzed the trends over time of biomarkers related with development and progression of AC in incident patients on peritoneal dialysis (PD). METHODS: We performed a prospective study with 186 patients on PD followed up for 1 year...

BACKGROUND: The importance of vasopressin and/or urine concentration in various kidney, cardiovascular, and metabolic diseases has been emphasized recently. Due to technical constraints, urine osmolality (Uosm), a direct reflect of urinary concentrating activity, is rarely measured in epidemiologic studies. METHODS: We analyzed 2 possible surrogates of Uosm in 4 large population-based cohorts (total n = 4,247) and in patients with chronic kidney disease (CKD, n = 146)...

BACKGROUND: Hypothesizing that statins may be useful as adjuvant treatment for renal anemia, we examined the association between statin prescription (Rx) and erythropoiesis-stimulating agent (ESA) hyporesponsiveness in Japanese hemodialysis (HD) patients prescribed ESAs. METHODS: We examined 3,602 patients in 60 HD facilities dialyzed 3 times/week for ≥4 months from the Japan Dialysis Outcomes and Practice Patterns Study phases 3-5 (2005-2015). Statin Rx was reported at the end of a 4-month interval (baseline) for each patient...

BACKGROUND: Recent reports have highlighted that diabetic patients with kidney failure are at increased risk of technique failure and transfer to haemodialysis within 90 days of initiating peritoneal dialysis (PD). We wished to determine whether there were differences between diabetic and non-diabetic patients within the first 3 months of starting PD. METHODS: We reviewed results of corresponding bioimpedance and the 1st test of peritoneal membrane function (PET) in consecutive patients, 6-10 weeks after initiating PD electively...
