BACKGROUND Acute kidney injury (AKI) secondary to sepsis is a major cause of morbidity and mortality in the human intensive care unit (ICU). Kidney function and the histological findings of AKI were investigated in an experimental rat model with sepsis induced by cecal ligation and puncture (CLP) and compared with and without treatment with carnosine (beta-alanyl-L-histidine). MATERIAL AND METHODS Twenty-four Sprague-Dawley rats were randomly divided into three groups consisting eight rats in each: Group 1 - control; Group 2 - septic shock; and Group 3 - septic shock treated with carnosine...

Colistin is a last resort antibiotic to treat multidrug-resistant Gram-negative bacteria infections. Colistin is administered intravenously in the form of its inactive prodrug colistin methanesulfonate (CMS). For patients with acute kidney impairment and continuous renal replacement therapy high extracorporeal clearance may cause a substantial removal of active colistin from the bloodstream, eventually decreasing its antibacterial efficacy. Currently recommended doses of CMS may therefore be inadequate for these patients...

Chronic renal failure (CRF) is a frequent condition in elderly subjects, and it is associated with psychiatric comorbidity, especially depressive symptoms. Purpose of the present research was to compare patients with different severity of chronic kidney disease (CKD) in terms of psychiatric symptoms. One hundred CKD subjects were randomly selected among those attending the Department of Nephrology, University of Milan. The patients were evaluated through the following rating scales: Mini-Mental State Examination (MMSE), Beck Depression Inventory (BDI), Symptom Checklist (SCL-90), Kidney Disease Quality of Life- Short Form (KDQOL-SF) and Cumulative Illness Rating Scale (CIRS)...

Paul M Palevsky
Acute renal replacement therapy is one of the most common interventions provided by nephrologists, however, data on the quality of training provided to nephrology fellows is limited. Extensive curricula for acute renal replacement therapy and the management of poisonings and intoxications have been published, but personal experience suggests that there are significant opportunities to improve training. Particular areas to be considered include the use of novel technologies for assessment of volume status, greater emphasis on the dosing of medications during acute renal replacement therapy, greater training in assessing and tailoring treatment to the goals of care of the individual patient, incorporation of continuous quality improvement tools into the management of acute renal replacement therapy programs and development of robust simulation training to augment training...

Ankit Sharma, Anne M Durkan
BACKGROUND: Transplantation is the preferred modality for renal replacement therapy in children. With increasing rates of re-transplantation within the paediatric population, there are more sensitised children on waiting lists. One issue with developing strategies to treat these children is the number of different definitions of sensitisation. and we would therefore recommend an immunological risk stratification approach. METHODS: We discuss methods of sensitisation prevention, assessment and management, including paired exchange programmes and desensitisation protocols...

The objective of this study was to evaluate prevalence, initial risk factors, and outcomes in Henoch-Schönlein purpura nephritis (HSPN) patients in Latin America. Two hundred ninety-six patients (validated EULAR/PRINTO/PRES HSP criteria) were assessed by demographic data, clinical/laboratorial involvements, and treatments in the first 3 months after diagnosis. They were followed-up in a Latin American tertiary center and were divided in two groups: with and without nephritis. Persistent non-nephrotic proteinuria, nephrotic proteinuria, and acute/chronic kidney injury were also systematically evaluated at 1, 5, 10, and 15 years after diagnosis...

REVIEW
D Kindgen-Milles, T Slowinski, T Dimski
Acute kidney injury (AKI) occurs in 30-50% of all intensive care patients. Renal replacement therapy (RRT) has to be initiated in 10-15%. The early in-hospital mortality is about 50%. Up to 20% of all survivors develop chronic kidney disease after intensive care discharge and progress to end-stage kidney disease within the next 10 years. For timely initiation of prophylactic or therapeutic interventions, it is crucial to exactly determine the actual kidney function, i. e., glomerular filtration rate (GFR), and to gain insight into the further development of kidney function...

Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of α-galactosidase A (α-gal A), leading to the progressive accumulation of glycosphingolipids. Classical hemizygous males usually present symptoms, including pain and paresthesia in the extremities, angiokeratoma, hypo- or anhidrosis, abdominal pain, cornea verticillata, early stroke, tinnitus, and/or hearing loss, during early childhood or adolescence. Moreover, proteinuria, renal impairment, and cardiac hypertrophy can appear with age...

INTRODUCTION: Young adults fare worse than younger adolescents or older adults on a broad range of health indicators. Those with a chronic illness such as renal failure are a particularly vulnerable group, who experience poor outcomes compared with both children and older adults. Understanding how being in receipt of renal replacement therapy (RRT) affects the lives of young adults might help us to better prepare and support these individuals for and on RRT, and improve outcomes. This study aimed to synthesise research describing young adults' experiences of the psychosocial impact of kidney failure and RRT...

Renal tissue hypoxia is a final pathway in the development and progression of chronic kidney disease (CKD), but whether renal oxygenation predicts renal function decline in humans has not been proven. Therefore, we performed a prospective study and measured renal tissue oxygenation by blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI) in 112 patients with CKD, 47 with hypertension without CKD, and 24 healthy control individuals. Images were analyzed with the twelve-layer concentric objects method that divided the renal parenchyma in 12 layers of equal thickness and reports the mean R2* value of each layer (a high R2* corresponds to low oxygenation), along with the change in R2* between layers called the R2* slope...

BACKGROUND: Shunt nephritis is a rare, reversible immune-complex mediated complication of CSF shunt infection that can progress to end-stage renal disease and even death if diagnosis is delayed. CASE DESCRIPTION: The present case report details the manifestation and clinical course of shunt nephritis in a 50-year old patient who presented with symptoms of nephrotic syndrome 30 years after ventriculo-jugular shunt placement. Diagnosis was delayed due to initial negative CSF and blood cultures but later a CSF culture was positive for Propionibacterium acnes...

PURPOSE OF REVIEW: The increasing incidence of acute kidney injury has the immediate effect of a growing need for renal replacement therapy (RRT). Shedding light on the questions of who, when, why, and how RRT should be performed is difficult to accomplish because of ambiguous study results, poor quality evidence, and low standardization. RECENT FINDINGS: Critically ill patients are exposed to multiple factors known to deteriorate kidney function. Especially severe fluid overload is strongly associated with worse outcome and may be considered as a trigger for initiating RRT...

Anti-microbial host defence is dependent on the rapid recruitment of inflammatory cells to the site of infection, the elimination of invading pathogens, and the efficient resolution of inflammation so as to minimise damage to the host. The peritoneal cavity provides an easily accessible and physiologically relevant system where the delicate balance of these processes may be studied. Here, we describe murine models of peritoneal inflammation that enable studies of both competent anti-microbial immunity and inflammation associated tissue damage as a consequence of recurrent bacterial challenge...

Background: Parathyroid failure is the most common complication after total thyroidectomy but permanent impairment of the parathyroid function is unusual. Limited data is available assessing long-term follow-up, quality of life and complications occurring in patients with permanent hypoparathyroidism (PH). We aimed to assess the incidence of complications derived from PH status, their influence on the quality of life perceived by PH patients and its relation to standard medical treatment with calcium salts and active vitamin D analogues...

BACKGROUND: Proton pump inhibitors are often used in critically ill patients to prevent gastrointestinal bleeding despite limited evidence for benefit. Patients with acute kidney injury requiring renal replacement therapy (RRT) are at high risk of gastrointestinal bleeding as (pre-)uremia induces coagulopathy through effects on platelets and coagulation cascades. No high-quality randomized clinical trials have previously assessed the benefits and harms of prophylactic proton pump inhibitor use in this high-risk population of adult critically ill patients...

Renal vein thrombosis (RVT) is a complication often associated with nephrotic syndrome. It occurs due to a state of hypercoagulability common in the diseases that attend to this syndromic diagnosis. It should be suspected whenever there is nephrotic syndrome associated with sudden flank pain, hematuria and worsening of proteinuria. Bilateral RVT also presents with frequently oliguric renal dysfunction. This case reports a 33-year-old patient hospitalized for a nephrotic syndrome, with etiologic investigation suggestive of primary membranous glomerulopathy, which evolved with bilateral RVT associated with deterioration of renal function and need for renal replacement therapy...

Patients with chronic kidney disease (CDK) can develop several diseases caused by the renal replacement therapy. Here we report a rare complication of peritoneal dialysis, the encapsulating peritoneal sclerosis (EPS) in which the peritoneal tissue is gradually replaced by fibrous tissue. The patient in question, after late loss of renal graft and conversion to peritoneal dialysis, evolved with multiple hospitalizations for spontaneous bacterial infections, in recent admission, he was diagnosed with sub-occlusive abdomen secondary to the EPS...

The pauci-immune crescentic glomerulonephritis (PICGN) is generally associated with small-vessel vasculitis with a few reported cases associated with other autoimmune diseases such as Systemic Lupus Erythematosus (SLE). We present the case of a female 34-year-old patient with acute kidney injury symptoms with indication for renal replacement therapy in the context of clinical SLE diagnosis. A kidney biopsy was conducted and it was found that most glomeruli showed some segmental sclerosis with synechia to the Bowman's capsule...

BACKGROUND: The effect of conversion to cytotoxic T-lymphocyte-associated protein 4 immunoglobulin (CTLA4Ig) treatment on tacrolimus (TAC)-induced renal dysfunction is well known, but its effect on TAC-induced diabetes mellitus (DM) is still undetermined. In the present study, we tested the diabetogenicity of CTLA4Ig and evaluated the effect of conversion to CTLA4Ig treatment on TAC-induced diabetic rats. METHODS: We tested diabetogenicity of CTLA4Ig by escalating doses (0...
