BACKGROUND: Predictive models of CS-AKI include emergency surgery and patients with haemodynamic instability. Our objective was to evaluate the performance of validated predictive models (Thakar and Demirjian) in elective cardiac surgery and to propose a better score in the case of poor performance. METHODS: A prospective, multicentre, observational study was designed. Data were collected from 942 patients undergoing cardiac surgery, after excluding emergency surgery and patients with an intraaortic balloon pump...

PURPOSE OF REVIEW: Historically, the identity of O2-sensing renal erythropoietin (Epo)-producing (REP) cells was a matter of debate. This review summarizes how recent breakthroughs in transgenic mouse and in-situ hybridization techniques have facilitated sensitive and specific detection of REP cells and accelerated advancements in the understanding of the regulation of renal Epo production in health and disease. RECENT FINDINGS: REP cells are a dynamically regulated unique subpopulation of tubulointerstitial cells with features of fibroblasts, pericytes and neurons...

BACKGROUND: Patients undergoing abdominal surgery for solid tumours frequently develop major postoperative complications, which negatively affect quality of life, costs of care and survival. Few studies have identified the determinants of perioperative complications in this group. METHODS: We performed a prospective observational study including all patients (age > 18) undergoing abdominal surgery for cancer at a single institution between June 2011 and August 2013...

Background Management of chronic renal failure requires complex medication regimens to manage hypertension, hyperlipidaemia, diabetes, phosphate, anaemia and acidosis. Patient engagement in medicine management is essential to avoid potential harm. Methods We prospectively audited the rate of discrepancies between our hospital record of patient medications and their current prescription. We investigated whether changes to appointment letters reduced the number of discrepancies. Results The proportion of patients attending renal outpatient clinics failing to bring a list or unable to recall their medications fell over a 3-year period following changes to appointment letters (median proportion: 0...

Thrombotic thrombocytopenic purpura is a rare condition that presents with microangiopathic haemolytic anaemia, thrombocytopaenia, fever, renal impairment and neurological symptoms. Plasma exchange is a lifesaving treatment for this condition. However, some cases may be non-responsive to plasma exchange, or loss of response may occur. Treatment options for refractory cases include high-dose corticosteroids, rituximab, vincristine, cyclophosphamide, splenectomy, bortezomib and N-acetylcysteine. We present a refractory case of thrombotic thrombocytopenic purpura responding to the last of these therapies...

Iron Deficiency (ID) is increasingly recognized as a prevalent comorbid condition in Heart Failure (HF). Despite this, the pathophysiological mechanisms for progressive ID in either chronic or acute HF are still poorly understood. Beyond the traditional factors for iron deficit in the general population, we ought to review the specificities of such paucity in the HF patient, particularly focusing on the interplay between heightened inflammation, overactivity of the sympathetic nervous system and the so-called cardio-renal-anaemia-ID syndrome...

A 37-year-old man with hepatitis C virus (HCV) genotype 3A developed renal failure. In 2007, the patient received a renal transplant and started receiving tacrolimus (Tac); the transplant subsequently failed. In April 2015, the patient restarted haemodialysis and in May initiated sofosbuvir 400 mg and ribavirin 400 mg daily. Baseline Tac level was 6.6 ng/mL and haemoglobin (Hb) was 10.3 g/dL. The patient then left the country for vacation and Hb was found to be dramatically low at 3.7 g/dL on return on 5 August...

BACKGROUND: Fanconi anaemia (FA) is an inherited disease with bone marrow failure, variable congenital and developmental abnormalities, and cancer predisposition. With improved survival, non-haematological manifestations of FA become increasingly important for long-term management. While renal abnormalities are recognized, detailed data on patterns and frequency and implications for long-term management are sparse. METHODS: We reviewed clinical course and imaging findings of FA patients with respect to renal complications in our centre over a 25-year period to formulate some practical suggestions for guidelines for management of renal problems associated with FA...

BACKGROUND AND OBJECTIVE: In patients with peripheral artery disease requiring surgery, anaemia has been found to independently predict short and medium term higher morbidity and mortality. PATIENTS AND METHODS: We retrospectively studied all patients undergoing surgery, consecutively during 2months in 12 vascular surgery units. We analysed cardiovascular risk factors and preoperative haemoglobin. Statistical analysis was done with Kaplan-Meier for survival and logistic regression modelling to identify predictors of mortality...

OBJECTIVES: The patient's body surface area serves as the traditional reference for the determination of systemic blood flow during cardiopulmonary bypass (CPB). New strategies refer to different algorithms of oxygen delivery. This study reports on the mixed venous oxygen saturation (Sv O2 ) as the target for systemic blood flow control. We hypothesise that an Sv O2 >75% (Sv O2 75) is associated with better preservation of renal function and improved short-term survival. METHODS: This retrospective, 10-year, observational study analysed 6945 consecutive cardiac surgical cases requiring CPB...

BACKGROUND AND AIMS: The advent of direct-acting antiviral agents promises to change the management of hepatitis C in patients with end-stage renal disease, a patient group where the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a 'real-world' group of patients with end-stage renal disease. METHODS: We performed a single-arm, multi-centre study in a cohort (n=30) of patients with advanced chronic kidney disease (mostly on dialysis) who underwent antiviral therapy with direct-acting antiviral agents...

AIMS: Insufficient erythropoietin (EPO) synthesis is a relevant cause of renal anaemia in patients with chronic kidney disease. Molidustat, a selective hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, increases endogenous EPO levels dose-dependently in preclinical models. We examined the pharmacokinetics, safety, tolerability and the effect on EPO levels after single oral doses of molidustat in healthy male volunteers. METHODS: This was a single centre, randomized, single-blind, placebo-controlled, group-comparison, dose-escalation study...

Systemic lupus erythematosus (SLE) is an autoimmune disease that affects many organs, but multisystem dysfunction is rare. Here, we report a case of a 29-year-old woman who was initially diagnosed with SLE complications including lupus nephritis, lupus encephalopathy, renal hypertension, thrombocytopenia, anaemia and hyperkalaemia. She recovered following treatment with high dose methylprednisolone, intravenous immunoglobulin (IVIG) and continuous renal replacement therapy (CRRT). However, a few days after hospital discharge, she developed gastrointestinal bleeding...

Acute kidney after cardiac surgery is more common in anaemic patients, whereas haemolysis during cardiopulmonary bypass may lead to iron-induced renal injury. Hepcidin promotes iron sequestration by macrophages: hepcidin concentration is reduced by anaemia and increased by inflammation. We analysed the associations in 525 patients between pre-operative anaemia (haemoglobin < 130 g.l-1 in men and < 120 g.l-1 in women), intra-operative hepcidin concentration and acute kidney injury (dialysis or > 26...

BACKGROUND: Patient blood management (PBM) is a multidisciplinary concept focused on the management of anaemia, minimisation of iatrogenic blood loss and rational use of allogeneic blood products. The aims of this study were: (i) to analyse post-operative outcome in patients with liberal vs restrictive exposure to allogeneic blood products and (ii) to evaluate the cost-effectiveness of PBM in patients undergoing surgery. MATERIALS AND METHODS: A systematic literature review and meta-analysis were performed to compare post-operative complications in predominantly non-transfused patients (restrictive transfusion group) and patients who received one to three units of red blood cells (liberal transfusion group)...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency leading to acute intravascular haemolysis and acute kidney injury (AKI) is a known clinical presentation. However, there is a paucity of information regarding the occurrence of rhabdomyolysis and myoglobinuria in G6PD-deficient individuals, especially children. An 11-year-old south Indian Tamil girl presented with severe anaemia and anuric AKI following a short febrile illness. Investigations demonstrated evidence of intravascular haemolysis and rhabdomyolysis, and on histopathology myoglobin deposits (casts) were detected in the renal tubules...
