For a number of years chronic kidney disease (CKD) has been listed in the group of lifestyle diseases, such as obesity, diabetes, cardiovascular disease and hypertension. It is estimated that in Poland more than 4 million people may suffer from various stages of CKD. Chronic kidney disease may also be a consequence of all the other civilization diseases. At the same time it is worth noting that nephrological problems are increasingly being taken into account in modern medical certification. The aim of this work is, among other things, to improve safe access to the labor for patients with kidney diseases...

Introduction: Automated acute kidney injury (AKI) electronic alerts are based on comparing creatinine with historic results. Methods: We report the significance of AKI defined by 3 "rules" differing in the time period from which the baseline creatinine is obtained, and AKI with creatinine within the normal range. Results: A total of 47,090 incident episodes of AKI occurred between November 2013 and April 2016. Rule 1 (>26 μmol/l increase in creatinine within 48 hours) accounted for 9...

Introduction: HIV-associated nephropathy (HIVAN) has been strongly linked to African ancestry. However, studies have demonstrated wide variability in the prevalence of HIVAN in different sub-Saharan African populations. Accurate assessment of the disease burden is important because antiretroviral therapy (ART) is increasingly available and may prevent progression to end-stage renal disease. Methods: We prospectively screened ART-naïve, afebrile, nonhypertensive, and nondiabetic adults attending a large HIV care program in Western Kenya for the presence of albuminuria (dipstick albumin ≥ trace or urine albumin to creatinine ratio [UACR] ≥ 30 mg/g)...

Simultaneous assessment of excretory liver and kidney function is still an unmet need in experimental stress models as well as in critical care. The aim of the study was to characterize two polymethine-dyes potentially suitable for this purpose in vivo. Plasma disappearance rate and elimination measurements of simultaneously injected fluorescent dyes DY-780 (hepato-biliary elimination) and DY-654(renal elimination) were conducted using catheter techniques and intravital microscopy in animals subjected to different organ injuries, i...

The incidence of acute kidney injury (AKI) will in the future remain high, partly due to an increase in comorbidities and other AKI favoring factors such as the rise in high-risk diagnostic and therapeutic interventions. AKI has emerged as a major public health concern with high human and financial costs. It has recently been demonstrated that patients surviving an AKI episode show increased all-cause mortality, chronic kidney disease (CKD), ESRD, cardiovascular events, and reduced quality of life. Although it is important to acknowledge that, after an AKI episode, the risk of dying by far exceeds the risk of developing incident or progressive CKD and/or entering a maintenance renal replacement therapy (RRT) program, currently only a minority of patients are referred for renal follow-up, even after AKI-requiring RRT...

A 50-year-old man with type II diabetes, hypertension and dyslipidemia, presented with non-oliguric acute kidney injury (AKI) and anemia. Renal biopsy showed acute tubular necrosis (ATN) with extensive cytoplasmic vacuolization and areas of tubulitis. These findings were ultimately attributed to dapagliflozin, which he started 3 months earlier due to poor glycemic control. ATN with similar microscopic findings has been described with larger doses of dapagliflozin in non-clinical trials. Our patient was started on dialysis and remained dialysis-dependent for 4 weeks while his renal function improved gradually thereafter...

Cellular phones are major sources of electromagnetic radiation (EMR) that can penetrate the human body and pose serious health hazards. The increasingly widespread use of mobile communication systems has raised concerns about the effects of cellphone radiofrequency (RF) on the hippocampus because of its close proximity to radiation during cellphone use. The effects of cellphone EMR exposure on the hippocampus of rats and the possible counteractive effects of ginkgo biloba (Egb761) were aimed to investigate...

Acute kidney injury (AKI) is associated with high mortality rates and predisposes development of chronic kidney disease (CKD). Distant organ damage, particularly in the lung, may contribute to mortality in AKI patients. Animal models of AKI demonstrate an increase in pulmonary infiltration of lymphocytes and reveal an acute compromise of lung function, but the chronic effects of AKI on pulmonary inflammation are unknown. We hypothesized that in response to renal I/R, there is a persistent systemic increase in Th17 cells with potential effects on pulmonary structure and function...

Fibrosis of the glomerular and tubulointerstitial compartments is a common feature of chronic kidney disease leading to end-stage renal failure. This fibrotic process involves a number of pathologic mechanisms, including cell death and inflammation. This review focuses on the role of the c-Jun amino terminal kinase (JNK) signaling pathway in the development of renal fibrosis. The JNK pathway is activated in response to various cellular stresses and plays an important role in cell death and inflammation. Activation of JNK signaling is a common feature in most forms of human kidney injury, evident in both intrinsic glomerular and tubular cells as well as in infiltrating leukocytes...

BACKGROUND: A Clostridium difficile-associated risk of death score was recently developed and validated by using a national cohort of both nonsurgical and surgical patients admitted with C difficile infection. However, risk scores specifically derived from surgical cohorts and designed for patients with C difficile infection are currently unavailable. OBJECTIVE: The aim of this study was to develop a risk of death score for patients with C difficile infection who are being considered for total abdominal colectomy because of the failure of medical therapy...

While statins are widely accepted as a keystone for secondary prevention of cardiovascular disease in the general population, statin treatment in chronic renal failure is still debated. Statins have shown no benefit on cardiovascular outcomes in 4D, AURORA, and SHARP trials conducted in patients on dialysis. However, no study has yet compared statin treatment after acute myocardial infarction in end-stage renal disease (ESRD) patients. Statin treatment significantly decreases overall mortality in ESRD patients with acute myocardial infarction compared to the non-statin group...

OBJECTIVE/BACKGROUND: Endovascular aneurysm repair (EVAR) may be associated with renal injury and more insight is needed into potential risk factors. The aim was to identify clinical, anatomical, and peri-procedural parameters as potential risk factors for the occurrence of acute kidney injury (AKI) and to evaluate chronic kidney disease (CKD) after EVAR. METHODS: A cohort of 212 consecutive patients who underwent elective EVAR for abdominal aortic aneurysm from January 2009 to October 2016 was included...

This study aimed to determine whether intravitreal administration of vascular endothelial growth factor inhibitors is associated with deterioration of renal function, as seen with systemic administration, in patients with diabetes and chronic kidney disease. Estimated glomerular filtration rates before and after 160 intravitreal injections of vascular endothelial growth factor inhibitors (aflibercept, bevacizumab, or ranibizumab) were compared in 69 patients with diabetes and with a baseline estimated glomerular filtration rate <60 mL/min/1...

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a common and potentially severe complication in patients with ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI). There is no consensus on the best definition of CI-AKI to identify patients at risk of haemodialysis or death. The objective of this study was to assess the association of CI-AKI, using four definitions, on inhospital mortality, mortality or haemodialysis requirement over 1-year follow-up, in patients with STEMI treated with pPCI...

About one third of patients with type 1 diabetes develops kidney disease. The mechanism is largely unknown, but intrarenal hypoxia has been proposed as a unifying mechanism for chronic kidney disease including diabetic nephropathy. The endothelin system has recently been demonstrated to regulate oxygen availability in the diabetic kidney via a pathway involving endothelin type A receptors (ETA-R). These receptors mainly mediate vasoconstriction and tubular sodium retention, and inhibition of ETA-R improves intrarenal oxygenation in the diabetic kidney...

Extracellular vesicles (EVs) are nanosized, membrane-bound vesicles released from different cells. Recent studies have revealed that EVs may participate in renal tissue damage and regeneration through mediating inter-nephron communication. Thus, the potential use of EVs as therapeutic vector has gained considerable interest. In this review, we will discuss the basic characteristics of EVs and its role in nephron cellular communication. Then, the application of EVs as therapeutic vector based on its natural content or as carriers of drug, in acute and chronic kidney injury, was discussed...

BACKGROUND: Extremely high temperatures over many consecutive days have been linked to an increase in renal disease in several cities. This is becoming increasingly relevant with heatwaves becoming longer, more intense, and more frequent with climate change. This study aimed to extend the known relationship between daily temperature and kidney disease to include the incidence of eight temperature-prone specific renal disease categories - total renal disease, urolithiasis, renal failure, acute kidney injury (AKI), chronic kidney disease (CKD), urinary tract infections (UTIs), lower urinary tract infections (LUTIs) and pyelonephritis...

BACKGROUND: Renal denervation (RDN) is a promising therapeutic method in cardiology. Its currently most investigated indication is resistant hypertension. Other potential indications are atrial fibrillation, type 2 diabetes mellitus and chronic renal insufficiency among others. Previous trials showed conflicting but promising results, but the real benefits of RDN are still under investigation. Patients with renal insufficiency and resistant hypertension are proposed to be a good target for this therapy due to excessive activation of renal sympathetic drive...

RATIONALE: Methylmalonic acidemia (MMA) is a common organic acidemia, mainly due to methylmalonyl-CoA mutase (MCM) or its coenzyme cobalamin (VitB12) metabolic disorders. Cobalamin C (CblC) type is the most frequent inborn error of cobalamin metabolism; it can develop symptoms in childhood and often combine multisystem damage, which leads to methylmalonic acid, propionic acid, methyl citrate, and other metabolites abnormal accumulation, causing nerve, liver, kidney, bone marrow, and other organ damage...
