BACKGROUND: Ischemia-reperfusion (I/R) injury is a common cause of patient morbidity and mortality in the perioperative period. Patients undergoing long-lasting, abdominal, and urogenital surgeries with risk factors such as advanced age, peripheral artery disease, diabetes mellitus, renovascular disease, and congestive heart failure are candidates for acute kidney injury (AKI) due to impaired renal perfusion and decreased functional renal reserve. Pharmacological agents with multiple functions and anti-oxidative and anti-inflammation properties may be promising preventative strategies for AKI...

Although the use of topical gentamicin has declined systemic gentamicin remains an important antimicrobial agent in the management of infections caused by multidrug-resistant gram-negative bacteria. Nephrotoxicity and Ototoxicity from systemic gentamicin is well documented despite normal gentamicin levels (peak and trough) and normal renal function tests Nephrotoxicity is a predisposing factor for vestibulotoxicity however vestibulotoxicity can still occur, in patients without nephrotoxicity [19 of 46 (43.1%) % in our series] much more significantly in single daily dosing (SDD) compared to multiple daily dosing (MDD) From our database of 46 patients we analyzed 19 patients with vestibulotoxicity without nephrotoxicity...

BACKGROUND: As immunosuppressive therapy and allograft survival have improved, the increased incidence of sepsis has become a major hurdle of disease-free survival after renal transplantation. METHODS: We identified 112 of 957 kidney transplant recipients (KTRs) with sepsis. 31 KTRs developed severe sepsis or septic shock, and 30 KTRs died from sepsis. KTRs without sepsis were used for comparison. CMV-specific and alloreactive T-cells were measured using an interferon-γ Elispot-assay...

Kidney transplant recipients are at an increased risk of developing surgical site wound complications due to their immunosuppressed status. We aimed to determine if increased mid-abdominal circumference (MAC) is predictive for wound complications in transplant recipients. A prospective study was performed on all kidney transplant recipients from October 2014 to October 2015. 'Controls' consisted of kidney transplant recipients without a surgical site wound complication and 'cases' consisted of recipients that developed a wound complication...

BACKGROUND: Peri-operative terlipressin (Tp) during living donor liver transplantation (LDLT) has been shown to reduce intra-operative portal pressures and improve renal function. Its role and safety profile has never been evaluated in a double-blinded RCT. AIM: To evaluate the haemodynamic effects, clinical benefits and safety of peri-operative terlipressin infusion in adult LDLT. METHODS: This was a single centre double-blind RCT. Consenting adults with chronic liver disease and low risk of post-transplant renal dysfunction (PTRD) undergoing their first LDLT were randomized...

Cisplatin, a first-generation platinum derivative, is one of the most widely used anticancer agents and can treat a broad spectrum of malignancies. Cisplatin-induced nephrotoxicity is a major dose-limiting side effect resulting from damage to the proximal tubules of the kidney. This nephrotoxicity can be prevented by lowering the concentration of cisplatin and shortening the period of cisplatin exposure to the proximal tubules. In clinical practice, high-volume hydration(>3 L intravenous isotonic saline), forced diuresis(mannitol and/or furosemide), and magnesium supplementation have been generally used to lower the risk of cisplatin-induced nephrotoxicity...

Despite the introduction of novel and more targeted immunosuppressive drugs, the long-term survival of kidney transplants has not improved satisfactorily. Early antigen-independent intra-graft inflammation plays a critical role in the initiation of the alloimmune response and impacts long-term graft function. Complement activation is a key player both in ischemia/reperfusion injury (IRI) as well as in adaptive anti-graft immune response after kidney transplantation. Since the alternative pathway (AP) amplifies complement activation regardless of the initiation pathways and renal IR injured cells undergo uncontrolled complement activation, we wondered whether selective blockade of AP could be a strategy for prolonging kidney graft survival...

OBJECTIVE: HIV-infected patients admitted to the hospital have complex antiretroviral therapy (ART) regimens with an increased medication error rate upon admission. This report is intended to provide a resource for clinicians managing HIV-infected patients and ART in the inpatient setting. METHODS: A survey of the authors was conducted to evaluate common issues that arise during an acute hospitalization for HIV-infected patients. After a group consensus, a review of the medical literature was performed to determine the supporting evidence for the following HIV associated hospital queries: admission/discharge orders, antiretroviral hospital formularies, laboratory monitoring, altered hepatic/renal function, drug-drug interactions (DDIs), enteral administration, and therapeutic drug monitoring...

Belatacept is a non-nephrotoxic immunosuppressive agent, which may make it the ideal agent for patients with delayed or slow graft function on calcineurin inhibitors. There are limited data on conversion of patients to belatacept within 6 months of transplantation. Between 1/2012 and 12/2015 sixteen patients were converted to belatacept for delayed or poor graft function (eGFR <30 ml/min/1.73m, MDRD); three were HIV+. Conversion protocols were analyzed in patients < 4 months and 4-6 months post transplantation...

In heart failure (HF), the reflex control of the heart rate is known to be markedly impaired; however, the baroreceptor control of the sympathetic drive remains under debate. Applying the sequence method to a series of arterial pressure (AP) and renal sympathetic nerve activity (RSNA), we demonstrated a clear dysfunction in the baroreflex control of sympathetic activity in rats with early HF. We analysed the baroreflex control of the sympathetic drive using three different approaches: AP vs. RSNA curve, cross-spectral analysis and sequence method between AP and RSNA...

Disseminated intravascular coagulation (DIC) is a fatal thrombohemorrhagic disorder. Bone marrow-derived mesenchymal stem cells (BMSCs) are multipotent stem cells that have tremendous therapeutic effect. Our aim was to explore whether the immune mechanisms were associated with BMSCs-afforded protection against DIC. We generated a rat model of DIC by lipopolysaccharide (LPS, 3 mg/kg) injection via the tail vein. In the treatment group, rats were pre-treated with 1 × l0(3) , 1 × l0(4) , 1 × l0(5) and 1 × l0(6) allogeneic BMSCs before LPS injection...

Chronic kidney disease (CKD) is an increasing clinical problem. Although clinical risk factors and biomarkers for the development and progression of CKD have been identified, there is no commercial surveillance technology to definitively diagnose and quantify the severity and progressive loss of glomerular filtration rate (GFR) in CKD. This has limited the study of potential therapies to late stages of CKD when FDA-registerable events are more likely. Because patient outcomes, including the rate of CKD progression, correlate with disease severity and effective therapy may require early intervention, being able to diagnose and stratify patients by their level of decreased kidney function early on is key for translational progress...

BACKGROUND: The current study aims to assess the association between acute kidney injury (AKI), renal function one year after transplantation and long-term adverse outcomes after cardiac transplantation. METHODS: A retrospective cohort study was performed including 471 adult cardiac transplantation recipients that survived the first postoperative year between 1984 and 2012. Primary outcome variables were long-term overall and renal survival. RESULTS: During the first postoperative week 40% (n=288) of the recipients developed AKI stage I, 22% (n=104) stage II, 13% (n=63) stage III and 4% (n=17) required temporary RRT...
