Audit of the Effect of Changing From IV to SC Administration of ESA's in Haemodialysis Patients...

Kidney FailureChronic1 more

The purpose of this study is to audit the effects of changing all hemodialysis patients from intravenous to subcutaneous administration of ESA's, to ensure that a cost-saving is achieved and that this does not occur at the expense of anemia control. The dose changes will occur according to usual clinical care of patients and not along a protocol.

Evaluation of Neutrophil Gelatinase-associated Lipocalin (NGAL) in Early and Evolving Acute Kidney...

Kidney FailureAcute

Some patients who undergo cardiovascular surgery requiring cardiopulmonary bypass will develop a kidney injury following their surgery. The purpose of this study is to take a blood sample from patients before they have this type of surgery and then at nine time points after their surgery to test their plasma for a biomarker called NGAL and compare the NGAL levels to their creatinine levels. We hypothesize that NGAL is an earlier marker for kidney injury than creatinine.

Improving Care for Peritoneal Dialysis Patients With the CKD-PD App

Kidney FailureChronic1 more

Managing the hydration status in patients undergoing peritoneal dialysis (PD) is a key task for nephrologists in Thailand that is made difficult due to lack of timely access to hydration metrics including weight, blood pressure, and ultrafiltration volume. This research project aims to improve the monitoring of hydration status in PD patients from a bimonthly, in-clinic review of a handwritten log-book to a smart phone based app (CKD-PD) with digitized data that allows for near real time monitoring hydration abnormalities, thereby creating the opportunity for earlier treatment of overhydration. The investigators hypothesize that use of the CKD-PD will improve early treatment of overhydration, and potentially reduce the incidence of complications, hospitalizations, and mortality in PD patients.

Effects of Endothelin Receptor Antagonist on Ischemic Kidney Injury During Nephron Sparing Surgery...

Kidney FailureAcute

Based on animal studies, it was found that administration of endothelial receptor antagonists before and after renal blood vessels clamp and release results in a significantly reduced renal function injury. On the basis of these results, we chose to divide the study population into 2 groups: control group that would be treated the standard accepted preventive treatment: intravenous injection of Mannitol, cooling of the kidney surface, compared to the treatment group that in addition would receive pre- and post-operative treatment of endothelial receptor antagonists (Ambrisentan (Volibris (10mg). To be noticed that the drug is recognized and is given as a primary indication for patients with pulmonary hypertension. The differences between the renal function and biomarkers for pre- and post-operative renal ischemic injury would be examined in order to disclose if the kidney injury of the treated group was indeed smaller. This information will enable us to protect the operated kidneys from the ischemic damage, especially in those patients with poor basic renal function.

Preventive Norepinephrine Infusion During Surgery for Upper Femoral Fracture and Post-operative...

Femur FractureAcute Renal Failure

The fracture of the upper extremity of the femur (FESF) is one of the most common fractures in traumatology. In France, FESF affects more than 65,000 individuals per year and could involve up to 150,000 people per year by 2050, due to the increase in life expectancy of the population. The main risk factors for the occurrence of ESF are: age, gender, osteoporosis, undernutrition, gait and balance disorders. The main risk factors for death identified by the French Society of Orthopaedic Surgery and Geriatrics after surgery for ESF are: a delay between the trauma and surgery of more than 48 hours, poorly tolerated preoperative anemia or a hemoglobinemia of less than 8 g/dl, absence of antibiotic prophylaxis, postoperative acute renal failure, and discontinuation of antiaggregant treatments in the case of coronary disease. Post-operative Acute Kidney Injury (AKI) is one of the risk factors for mortality after surgery for ESF. AKI is an impairment of normal kidney function, and in general, AKI is a major issue in the management of patients undergoing surgery. In the short term, it increases the length of stay of patients, and the number of admissions to continuing care. AKI increases post-operative mortality by more than 50%. However, because of the complications associated with vascular filling, the use of vasoconstrictor drugs, such as ephedrine, phenylephrine, and especially norepinephrine, is increasingly common. Compared with other catecholamines, norepinephrine has been shown to be more effective in increasing cardiac output. Moreover, unlike bolus administration of ephedrine or phenylephrine, which favor the occurrence of blood pressure peaks and valleys, norepinephrine, administered as a continuous infusion, allows blood pressure to be maintained in a narrower range. The challenge is to implement a strategy to reduce their frequency. Intraoperative arterial hypotension is one of the risk factors on which investigators can intervene thanks to the "preventive" administration of noradrenaline in continuous infusion, started before or immediately after the induction of anesthesia. However, the "preventive" use of norepinephrine may favor the occurrence of AKI in hypovolemic patients (fracture and surgery-related bleeding, prolonged fasting) by reducing renal blood flow. Our primary objective is to compare the risk of AKI occurrence during a "preventive" norepinephrine administration strategy with a target MAP ≥65 mmHg compared with that observed in response to a vasoconstrictor-only administration strategy in response to the occurrence of arterial hypotension episodes. Secondary objectives are to evaluate the potential interactions of this preventive strategy with other risk factors for postoperative AKI.

Hemostatic Profiles in Pediatric CKD

Kidney DiseaseChronic4 more

This cross-sectional pilot study will examine the blood clotting patterns in children with chronic kidney disease stages 3, 4, and 5. A total of 30 participants will be enrolled with 10 participants for each stage of chronic kidney disease. Blood specimens will be collected from each participant during a routine clinic visit, and will then be processed to evaluate blood clotting characteristics according to thrombelastography and more conventional clotting tests.

Impact of Donor-Specific Antibodies in (Highly-) Immunized Living Donor Kidney Transplant Recipients...

Renal Failure

Kidney transplantation is the preferred treatment for end-stage renal disease. Alongside limited availability of donors, rejection and premature graft loss are main barriers to kidney transplantation. Donor-specific antibodies pre-transplantation may arise due to to prior solid organ transplantation, pregnancy or blood transfusions. Their presence is considered a risk of graft failure. The impact of DSA is differently reported in literature, also according to the technique by which DSA have been measured. Techniques such as the complement-dependent cytotoxicity crossmatch, the immunofluorescence crossmatch and the Luminex Single Antigen Bead have different sensitivities for detecting DSA. Historically, our kidney transplant program has been advocating living donor transplantation and as a result the majority of transplantations are with a living donor. In this context and in the absence of a compatible living donor, pretransplant DSA have not been considered an absolute contra-indication for transplantation. The aim of the current study is to determine the effect of DSAs on rejection and death-censored graft survival in living donor kidney transplantation. Participants are adults who underwent a living donor kidney transplantation between 2010 and 2019 in the presence of DSA. Control subjects are both immunized and non-immunized kidney transplant recipients in the same period. This is a retrospective, case control study. Death-censored graft survival is analyzed for all patients and compared by presence of DSA and other predicting variables, such as immunization level, age, sex and HLA mismatches. Furthermore, biopsy proven rejection, patient survival, kidney function, length of hospital stay and proteinuria are analyzed. Also, a predefined subgroup analysis is performed in the DSA positive patients. These are compared according to amount, strength and HLA-class of DSAs.
