Transcatheter valve-in-valve implantation (ViV-TAVI) has evolved as an alternative to redo surgical valve replacement (redo-SAVR) for high-risk patients with aortic bioprosthetic valve (BPV) dysfunction. The differences in procedural success and outcomes in a large number of patients who underwent ViV-TAVI compared with redo-SAVR for aortic BPV dysfunction are not known. We conducted a meta-analysis of the previously reported studies to determine outcomes after ViV-TAVI and redo-SAVR. PubMed, MEDLINE, and Google Scholar databases were searched for studies that reported comparative outcomes of patients who underwent either ViV-TAVI or redo-SAVR...

We present a comparison between three left ventricular assist devices (LVADs): HeartWare (HVAD) (HeartWare International Inc., Framingham, MA, USA), HeartMate II (HMII) and HeartMate III (HMIII) (Thoratec Corp., Pleasanton, CA, USA). To our knowledge, no study to date has aimed at placing these three devices in juxtaposition. Between June 2007 and June 2017, 108 consecutive patients received HMII, n = 77 (71.3%), HVAD, n = 14 (13%), or HM III, n = 17 (15.7%), for end-stage heart failure. Mean age was 63...

Rhabdomyolysis is characterized by muscle cell death which can result in acute kidney injury from pigment nephropathy. We present a patient who developed rhabdomyolysis immediately after deceased donor kidney transplantation surgery and was managed with continuous renal replacement therapy that resulted in successful salvage of the kidney allograft. Patients who develop acute kidney failure requiring renal replacement therapy generally have a poor prognosis. It is worth noting that while continuous veno-venous hemofiltration (CVVHF) offers greater volume support and continuous clearance compared to hemodialysis (HD), recent studies have demonstrated no clinically significant improvement in clinical outcome between the two...

Deoxycholate amphotericin B (d-AMB) has a higher rate of acute kidney injury (AKI) in comparison of lipid formulations. However, lipid amphotericin B has high costs in developing countries. The aim of this study is to assemble a model of cost-minimization of amphotericin B lipid complex (ABLC) in patients with cryptococcal meningitis. This is a retrospective study done in a cohort of patients with cryptococcal meningitis to study the economic impact of its use in developing countries. Cost analysis were based on direct cost of different antifungal therapies, chronic dialysis after discharge, and survival of patients based on a retrospective cohort of 102 patients infected with human immunodeficiency virus with confirmed diagnosis of cryptococcal meningitis...

BACKGROUND: Prolonged duration of delayed graft function (DGF) may be associated with adverse allograft outcomes, but the association between threshold duration of DGF, acute rejection and long-term allograft loss remains undefined. We aimed to determine the impact of DGF duration on allograft outcomes and to assess whether this association was mediated by acute rejection. METHODS: Using data from the Australian and New Zealand Dialysis and Transplant (ANZDATA) registry, Cox proportional modelling was used to determine the association between quartiles of DGF duration, acute rejection at 6 months and death-censored graft loss (DCGL)...

Peritoneal dialysis (PD) is a means of renal replacement therapy (RRT) that can be performed in remote settings with limited resources, including regions that lack electrical power. PD is a mainstay of end-stage renal disease (ESRD) therapy worldwide, and the ease of initiation and maintenance has enabled it to flourish in both resource-limited and resource-abundant settings. In natural disaster scenarios, military conflicts, and other austere areas, PD may be the only available life-saving measure for acute kidney injury (AKI) or ESRD...

Central venous (CV) catheterization is not only an invaluable diagnostic modality but also an essential therapeutic tool for the treating physician, enabling rapid and reliable intravenous administration of drugs and fluids, providing venous access to patients undergoing long-term continuous or repeated intravenous treatment such as chemotherapy or it can be used for haemodialysis in patients suffering from acute or chronic renal disease. On the other hand, CV catheterization can lead to a wide range of life-threatening complications for the patient especially if left untreated or become late-diagnosed...

BACKGROUND: Preoperative hyponatremia adversely impacts outcomes of cardiothoracic surgery. However, in patients with chronic kidney disease, the association of sodium levels on postoperative events has never been evaluated. We investigated the impact of preoperative hyponatremia on outcomes after cardiac surgery in patients with non-dialysis-dependent chronic kidney disease. Primary endpoints were operative mortality and acute kidney injury requiring dialysis. Secondary endpoints were major infection and long-term survival...

Extracorporeal membrane oxygenation (ECMO) is considered a recognized lifesaving support for patients with cardiorespiratory failure. Acute kidney injury (AKI) and fluid overload are significant morbidity factors resulting in serious complications. The inline hemofilter system (IHS) and the continuous renal replacement therapy (CRRT) machine are different methods of renal replacement therapy for patients with ECMO. IHS is the alternate, safe dialysis modality of choice because it is user-friendly, inexpensive, and efficiently removes fluid overload and renal diffusive clearance...

Acute kidney injury (AKI) is common in critically ill patients and associated with increased morbidity and mortality. With the increased use of renal replacement therapy (RRT) for severe AKI, the optimal time for initiation of RRT has become one of the most probed and debated topic in the field of nephrology and critical care. There appears to be an increased trend toward earlier initiation of RRT to avoid life-threatening complications associated with AKI. Despite the presence of a plethora of studies in this field, the lack of uniformity in study design, patient population types, definition of early and late initiation, modality of RRT, and results, the optimal time for starting RRT in AKI still remains unknown...

Acute kidney injury (AKI) is one of the most common serious complications for all hospital admissions, with its incidence increasing among hospitalized patients, particularly those in the intensive care unit. Despite significant improvements in critical care and dialysis technology, AKI is associated with an increased risk of short- and long-term mortality, prolonged hospital stays, and dialysis dependence. These risks are particularly relevant for critically ill patients with AKI severe enough to require renal replacement therapy (RRT)...

Hydralazine is a direct-acting vasodilator, which has been used in treatment for hypertension (HTN) since the 1950s. While it is well known to cause drug-induced lupus (DIL), recent reports are indicating the emergence of the drug-induced anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (DIV). Herein, we describe two patients (aged 57 and 87 years) who presented with severe acute kidney injury (AKI), proteinuria, and hematuria. Both were receiving hydralazine for the treatment of hypertension...

BACKGROUND: Dialysis-requiring acute kidney injury (D-AKI) is a serious complication in hospitalized heart failure (HF) patients. However, data on national trends are lacking after 2002. METHODS: We used the Nationwide Inpatient Sample (2002-2013) to identify HF hospitalizations with and without D-AKI. We analyzed trends in incidence, in-hospital mortality, length of stay (LoS) and cost. We calculated adjusted odds ratios (aOR) for predictors of D-AKI and for outcomes including in-hospital mortality and adverse discharge (discharge to skilled nursing facilities, nursing homes, etc)...
