Ultrasound Assessment of Volume in Patients on Continuous Dialysis

Renal failure and resuscitation measures in critically ill patients can result in fluid overload. Fluid overload in renal failure patients can cause harmful effects like pulmonary edema, anasarca and congestive cardiac failure exacerbations among other complications. These have been associated with increased time on the ventilator, increased length of stay in the ICU, and higher overall mortality for patients requiring dialysis in the ICU. The current standard of care for adjusting fluid removal rates in patients on continuous renal replacement therapy relies on clinical judgement. Clinicians take into account factors like the patient's condition, vasopressor requirements, kidney function, total intake and outputs, vital signs, and physical examination findings when making daily changes to fluid removal rates on dialysis machines. Such assessment is highly subjective and can be imprecise/inaccurate leading to hypotension and hemodynamic instability in a critically ill patient. Use of conventional ultrasound by physicians to assess volume status using compressibility of the inferior vena cava has been shown to be a reliable predictor of volume status and can help guide therapy. Such use makes bedside volume assessment a non-invasive, rapid, repeatable point of care tool that can provide objective data to guide fluid removal determine velocity of fluid removal and help identify patients at risk of hypotension and hemodynamic instability during the process of fluid removal. Apart from rare possible local allergic reactions to ultrasound jelly and transient local discomfort, the disadvantages are minimal. Ultrasonography has been considered a safe imaging modality. This protocol will measure inferior vena cava compressibility using the General Electric VScan with Dual Probe, which has FDA approval for abdominal and vascular imaging in humans.

Everolimus Plus Mycophenolic Acid for Kidney Preservation in Liver Transplant Recipients With Impaired Kidney Function

Tacrolimus is the standard immunosuppressive drug used to prevent organ rejection post liver transplant. One side effect of Tacrolimus is nephrotoxicity. Everolimus does not have the nephrotoxicity side effects of Tacrolimus. Replacement of Tacrolimus by Everolimus may have a reduced incidence of renal dysfunction in liver transplant patients who already have chronic kidney disease or peri-operative acute kidney injury. Liver transplant patients receive potent induction immunosuppression in the form of rabbit anti thymocyte globulin. Investigators believe that in conjunction with this induction regimen, patients can be maintained on Everolimus monotherapy without the risk of rejection. Additionally, Everolimus is known to induce tolerance in transplant recipients. Tolerant patients do not require immunosuppression to accept transplant organs. Tacrolimus is a widely used in liver transplant recipients for immunosuppression, however it is associated with nephrotoxicity. Everolimus, on the other hand lacks nephrotoxicity. Whether replacement of tacrolimus by Everolimus preserves kidney function in patients with pre-existing chronic kidney disease or acute kidney injury is not well established. Also, the efficacy and safety of reduced-dose Everolimus with or without Mycophenolate Mofetil in prevention of rejection is unknown. Primary Aim Assess the effect of Everolimus with or without Mycophenolate Mofetil versus Tacrolimus plus Mycophenolate Mofetil therapy on renal function measured by Glomerular Filtration Rate (GFR). Secondary Aims Compare the efficacy of Everolimus plus Mycophenolate Mofetil versus Tacrolimus plus Mycophenolate Mofetil therapy as measured by the following: Biopsy-confirmed acute rejection Hyperlipidemia Proteinuria % regulatory T-cells in circulation NODAT [New Onset Diabetes mellitus After Transplant], hypertension and malignancy Tolerance measured by gene profiling at year 1, 2 and 3

Everolimus Monotherapy as Immunosuppression After Liver Transplant

Tacrolimus is the standard immunosuppressive drug used to prevent organ rejection post liver transplant. One side effect of Tacrolimus is nephrotoxicity. Everolimus does not have the nephrotoxicity side effects of Tacrolimus. Replacement of Tacrolimus by Everolimus may have a reduced incidence of renal dysfunction in liver transplant patients who have near normal kidney function prior to liver transplantation. Other investigators have already shown a benefit in terms of renal function with introduction of Everolimus with reduced-exposure tacrolimus at 1 month after liver transplantation, this benefit has been shown was maintained to 3 years in patients who continued Everolimus therapy with comparable efficacy and no late safety concerns. Investigators in this trial are proposing to advance this approach further by completely eliminating Tacrolimus from patients' immunosuppression protocol. The rationale for this approach is based on a unique induction immunosuppression protocol. Liver transplant patients receive potent induction immunosuppression in the form of rabbit anti thymocyte globulin. Investigators believe that in conjunction with this induction regimen, patients can be maintained on Everolimus monotherapy without the risk of rejection. By completely eliminating Tacrolimus, investigators believe that there may be further benefit in terms of renal function. Additionally, Everolimus is known to induce tolerance in transplant recipients. Tolerant patients do not require immunosuppression to accept transplant organs. The long-term efficacy and safety of Everolimus monotherapy as the maintenance immunosuppression in patients receiving rATG induction is unknown. Primary Aim: Assess the effect of Everolimus monotherapy versus Tacrolimus monotherapy on long term renal function measured by Glomerular Filtration Rate (GFR).
