OBJECTIVES: This study was conducted to clarify the relationship between body mass index and mitral valve (MV) surgery and to determine whether an 'obesity paradox' exists in the context of surgery for degenerative MV disease. METHODS: In this retrospective single-centre study, we analysed data from 715 patients who underwent mitral surgery for degenerative disease from 2000 to 2015. Patients were classified according to body mass index: underweight (<20 kg/m 2 ), normal weight (20-24...

Atypical hemolytic-uremic syndrome (aHUS) is a rare disease of complement dysregulation leading to thrombotic microangiopathy (TMA). Renal involvement and progression to end-stage renal disease are common in untreated patients. We report a 52-year-old female patient who presented with severe acute kidney injury, microangiopathic hemolytic anemia, and thrombocytopenia. She was managed with steroid, plasma exchange, and dialysis. Kidney biopsy shows TMA and renal cortical necrosis. Genetic analysis reveals heterozygous complement factor I (CFI) mutation...

Background: Acute kidney injury (AKI) is common after coronary artery bypass grafting (CABG) and is associated with poor outcome. Increased hospital procedure volume has been associated with better outcomes. However, the impact of hospital CABG volume on AKI needing dialysis (AKI-D) is less clear. We designed this study to examine (i) the impact of number of annual CABG procedures per hospital (CABG-vol) on AKI-D and inpatient mortality and (ii) if it modifies the relationship between AKI-D and mortality...

Early recognition of acute kidney injury (AKI) is critical to prevent its associated complications as well as its progression to long term adverse outcomes like chronic kidney disease. A growing body of evidence from both laboratory and clinical studies suggests that inflammation is a key factor contributing to the progression of AKI regardless of the initiating event. Biomarkers of inflammation are therefore of interest in the evaluation of AKI pathogenesis and prognosis. There is evidence that the renin angiotensin aldosterone system is activated in AKI, which leads to an increase in angiotensin II (Ang II) formation within the kidney...

Hydrogen sulfide (H2S) is synthesized in nearly all organ systems including the kidney. Recent findings have revealed that H2S functions as a gasotransmitter affecting a wide range of physiologic functions similar to other gasotransmitters nitric oxide (NO) and carbon monoxide (CO). Research on H2S regulation of kidney function is still in early stages. H2S increases glomerular filtration rate (GFR) and inhibits sodium absorption by the tubules. There is burgeoning evidence that H2S generation by kidney cells is reduced in acute and chronic disease states and that H2S donors ameliorate injury...

Current genome-editing systems generally rely on inducing DNA double-strand breaks (DSBs). This may limit their utility in clinical therapies, as unwanted mutations caused by DSBs can have deleterious effects. CRISPR/Cas9 system has recently been repurposed to enable target gene activation, allowing regulation of endogenous gene expression without creating DSBs. However, in vivo implementation of this gain-of-function system has proven difficult. Here, we report a robust system for in vivo activation of endogenous target genes through trans-epigenetic remodeling...

AIM: Paediatric palliative care is no longer restricted to patients with cancer and has been extended to patients with other chronic conditions, such as cystic fibrosis or neuromuscular disorders. This review focused on the current state of palliative care for children and adolescents with chronic kidney disease (CKD). METHOD: We assessed the literature on CKD published up to August 2017. All the papers, except one from 1996, were published this century. This review discusses the role that palliative care plays in the process of decision-making and explores the possibilities of implementing palliative care into the routine therapy of affected patients and providing support for their families...

Hepatitis C virus infection is highly prevalent among kidney transplant recipients, occurring consequently to their previous treatment with hemodialysis. Hepatitis C virus infection has been associated with lower graft and patient survival compared with that shown in patients without infection. The lower survival has been associated with the posttransplant progression of liver disease and increased risk for development of extrahepatic complications. The choice of immunosuppressive drugs could significantly affect the course of the infection with an accelerated viral replication after kidney transplant...

Acute interstitial nephritis (AIN) is a condition in which acute kidney injury (AKI) is characterized by the histological finding of interstitial inflammation. Hyponidd is an ayurvedic drug containing Momordica charantia, Gymnema sylvestre, Swertia chirata, etc., used for the treatment of Type 2 diabetes mellitus (DM) and polycystic ovarian disease as an insulin sensitizer. There are no case reports of AIN caused by this drug yet. We report a biopsy-proven case of AKI due to severe AIN associated with the use of hyponidd tablet in a 60-year-old male with DM and hypertension...

Vitamin D, either in its D2 or D3 form, is essential for normal human development during intrauterine life, kidney function and bone health. Vitamin D deficiency has also been linked to cancer development and some autoimmune diseases. Given this huge impact of vitamin D on human health, it is important for daily clinical practice and clinical research to have reliable tools to judge on the vitamin D status. The major circulating form of vitamin D3 is 25-hydroxyvitamin D3 (25(OH)D), although is not the most active metabolite, the concentrations of total 25-hydroxy vitamin D3 in the serum are currently routinely used in clinical practice to assess vitamin D status...

Acute kidney injury (AKI) is a relatively common condition, encountered in everyday paediatric clinical practice. It is an important cause of morbidity and mortality in children both inside and outside intensive care units. It is associated with prolonged hospital stay and progression to chronic kidney disease. The burden of AKI is particularly high in low- and middle-income countries where rural areas and smaller cities in the countryside predominate. Most of these areas suffer from poverty, poor sanitation, water quality and hygiene, lack of education and poor access to health care...

BACKGROUND: Uremic toxins that accumulate in chronic kidney disease (CKD) contribute to CKD complications, such as CKD progression. Bisphenol A (BPA) is a ubiquitous environmental toxin, structurally related with p-cresol, that accumulates in CKD. Our aim was to characterize the nephrotoxic potential of BPA. Specifically, we addressed BPA toxicity over energy-demanding proximal tubular cells. METHODS: Cell death and oxidative stress were evaluated by flow cytometry and confocal microscopy in HK-2 human proximal tubular epithelial cells...

Shiga toxin (Stx)-producing Escherichia coli (STEC) is the offending agent in post-diarrhea-associated hemolytic uremic syndrome (HUS), a disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney failure, with thrombi occluding the renal microvasculature. Endothelial dysfunction has been recognized as the trigger event in the development of microangiopathic processes. Glomerular endothelial cells are susceptible to the toxic effects of Stxs that, via nuclear factor kappa B (NF-κB) activation, induce the expression of genes encoding for adhesion molecules and chemokines, culminating in leukocyte adhesion and platelet thrombus formation on the activated endothelium...
