Acute kidney injury (AKI) is independently associated with significant morbidity and mortality, and is thus an important challenge facing physicians in modern healthcare. This narrative review assesses the impact of strategies employed to tackle AKI following the 2009 NCEPOD report on acute kidney injury (Sterwart et al. Acute kidney injury: adding insult to injury, pp 1-22, 2009). There is scarce and heterogeneous research into hard end points such as mortality and AKI progression for AKI interventions. This review found that e-alerts have varying effects on mortality and AKI progression, but decrease the incidence of contrast-induced AKI...

BACKGROUND: Epstein-Barr virus (EBV) was the first human virus identified to express microRNA (miRNA). To date, 44 mature miRNAs are encoded for within the EBV genome. EBV miRNAs have not been profiled in paediatric renal transplant recipients. In this study, we investigated circulating EBV miRNA profiles as novel biomarkers in paediatric renal transplant patients. METHODS: Forty-two microRNAs encoded within 2 EBV open reading frames (BART and BHRF) were examined in renal transplant recipients who resolved EBV infection (REI) or maintained chronic high viral loads (CHL), and in non-transplant patients with acute infectious mononucleosis (IM)...

BACKGROUND: Acute kidney injury (AKI) following acute ST elevation myocardial infarction (STEMI) is associated with adverse outcomes. The recently proposed KDIGO criteria suggested modifications to the consensus classification system for AKI, namely lowering the threshold of increase in absolute serum creatinine and extending the time frame for AKI detection to 7 days. We evaluated the incidence, risk factors, and long-term mortality associated with AKI as classified by the KDIGO definition in a large single center cohort of consecutive STEMI patients...

BACKGROUND: The widely used International Study of Kidney Disease in Children (ISKDC) classification for Henoch-Schönlein purpura nephritis (HSPN) does not completely correlate with the clinical presentation and long-term prognosis of this disease. Primary IgA nephropathy (IgAN) and HSPN share common features; thus, the Oxford classification of IgAN might be useful in predicting the long-term outcomes of HSPN. However, its value has not been confirmed in children with HSPN. METHODS: We selected children with HSPN diagnosed between 2003 and 2015, and reclassified their renal biopsies according to the Oxford classification scoring system...

Previous reports identify a voltage dependent distal renal tubular acidosis (dRTA) secondary to lithium (Li+) salt administration. This was based on the inability of Li+-treated patients to increase the urine-blood (U-B) pCO2 when challenged with NaHCO3 and, the ability of sodium neutral phosphate or Na2SO4 administration to restore U-B pCO2 in experimental animal models. The underlying mechanisms for the Li+-induced dRTA are still unknown. To address this point, a 7 days time course of the urinary acid-base parameters was investigated in rats challenged with LiCl, LiCitrate, NaCl, or NaCitrate...

Recently, a number of reports have described dominant C3 deposits in renal biopsies of patients with infection-related glomerulonephritis (GN). While acute post-infectious GN and membranoproliferative GN are commonly characterized by immune deposits containing C3 and/or C4, the absence of immunoglobulin (Ig) and/or immune complexes at light or electron microscopy is a rather unusual observation. Dominant C3 deposition is believed to result from the alternative pathway of complement activation via the C3bBb "tickover" convertase...

OBJECTIVES: Acute kidney injury (AKI) is common in hospitalized children. The impact of AKI following hospitalization is not fully understood, particularly the impact on health related quality of life (HRQOL). The goal of this study was to determine the relationship between hospitalization-associated AKI and HRQOL in a pediatric population. STUDY DESIGN: We conducted a retrospective cohort study of children with hospitalization-associated AKI. Eligible children were 1-19 years old with AKI defined by kidney disease improving global outcomes (KDIGO) criteria and had at least one completed pediatric quality of life (PedsQL) 4...

BACKGROUND: High altitude renal syndrome has been described in populations with excessive erythrocytosis. We evaluated whether high altitude (HA) dwellers might be at increased risk for kidney disease. METHODS: We performed a cross-sectional study to investigate differences in prevalence of kidney function and metabolic syndrome in healthy subjects living at HA vs. sea level (SL) without any known history of hypertension, diabetes or chronic kidney disease. RESULTS: We examined 293 subjects, aged 40 to 60 years: 125 SL (154 m) and 168 HA (3640 m) dwellers...

BACKGROUND: The association of metabolic syndrome (MetS) traits with urinary calcium (UCE) or oxalate excretion (UOE) is uncertain in calcium stone formers (CSFs). Our aim was to investigate this association in a large group of Caucasian CSFs. METHODS: We retrospectively reviewed data of CSFs evaluated at our Kidney Stone Clinic from 1984 to 2015. Data on body mass index (BMI), MetS traits defined according to international consensus, family history of urolithiasis, anti-hypertensive treatments, calcemia, renal function, and 24-h urinary profile of lithogenic risk were collected...

Autoantibody against phospholipase A2 receptor (anti-PLA2R) is a sensitive and specific biomarker of idiopathic membranous nephropathy (iMN), being found in approximately 70% of iMN patients and only occasionally in other glomerular diseases. However, whereas its diagnostic specificity vs. normal controls and other glomerulonephritides (GN) has been firmly established, its specificity vs. membranous nephropathy associated with various diseases (sMN) has given inconsistent results. The aim of our study was to evaluate the prevalence of anti-PLA2R antibodies in iMN in comparison with various control groups, including sMN...

AIMS: The management of chronic kidney disease (CKD) complications is not always adequate in patients with a failed kidney transplant. We aimed to evaluate the frequency of CKD complications and assess whether they may lead to worse outcomes in this patient population. METHOD: We analyzed 49 kidney transplant recipients with a failed transplant (T+) and matched non-transplanted patients (T-) starting dialysis between 2000 and 2010 in five dialysis centers in France...

Hepatitis C virus (HCV) infection is one of the main causes of liver cirrhosis worldwide. The long-term impact of HCV infection is highly variable, ranging from minimal histological changes to extensive fibrosis with hepatocellular carcinoma. The development of HCV drugs has increased dramatically in recent years, even in special populations such as chronic kidney disease patients. Classical treatment of chronic hepatitis C was based on the administration of interferon and ribavirin for 24-48 weeks, which was associated with a poor viral response and a high rate of side effects, especially in patients with a lower estimated glomerular filtration rate...

AIM: To determinate the prognostic significance of low serum C3 at the time of diagnosis of ANCA-associated vasculitis (AAV). METHODS: Our cohort included 75 consecutive patients with AAV diagnosed from January 2005 to December 2015. C3 levels were measured at the time of diagnosis. Patients were divided into two groups, those with low serum C3 levels (< 0.9 g/l) and those with normal serum C3 levels (0.9-1.8 g/l). We analysed association between serum C3 levels and both combined and singularly patient and renal survival (ESRD)...

The incidence of acute kidney injury in pregnancy (P-AKI) in developed countries is significantly lower than in developing ones, where it is estimated to range between 4 and 26%. Mortality in cases of P-AKI requiring dialysis is high, varying from 20 to 80%. In developing countries, clinical decisions are often based on the availability of services and not on needs. Prenatal surveillance in Mexico does not include serum creatinine, limiting the potential for early diagnosis of AKI and CKD and their differential diagnosis...

Distal renal tubular acidosis (dRTA) is a tubular disorder with a primary defect of urinary acidification and acid excretion in the collecting duct system. Consequently, patients develop hyperchloremic metabolic acidosis with an inappropriately alkaline urine. Inherited forms of dRTA are due to mutations in at least three distinct genes: SLC4A1, ATP6V1B1, ATP6V0A4. Mutations in SLC4A1-(AE1) are inherited either in an autosomal dominant manner or in a recessive one. ATP6V1B and ATP6V0A4 mutations affect two different subunits of the vacuolar H+-ATPase proton-pump, the B1 and a4 subunits, and are inherited in an autosomal recessive manner...
