To evaluate Renal outcomes among patients, post liver transplantation at Assiut university.
Full description
It is estimated that 1 in 4 liver transplantation (LT) recipients has an estimated glomerular filtration rate (eGFR) of <60mL/minute/1.73 m2 at the time of LT Renal dysfunction, both before or after LT, is an important comorbidity associated with an increased risk of death, morbidity, and cost. Serum creatinine, a major component of the Model for End-Stage Liver Disease (MELD) score, has driven the increased incidence of renal dysfunction among patients undergoing LT End-stage liver disease (ESLD) is commonly complicated by kidney dysfunction, which in turn leads to a worse prognosis. The kidney dysfunction can be functional or structural, ranging from prerenal azotemia and hepatorenal syndrome causing acute kidney injury to immunoglobulin A (IgA) nephropathy (IgAN) and membranoproliferative glomerulonephritis causing chronic kidney disease Each condition carries a different presentation, treatment, prognosis, and risk of recurrence. Therefore, when ESLD patients undergo evaluation for liver transplant, it is critical to assess their kidney function and understand the cause of any underlying kidney dysfunction LT recipients will continue to worsen due to calcineurin inhibitor toxicity and lack of recovery from hepatorenal syndrome (HRS), necessitating renal replacement therapy Patients who are not expected to recover their kidney function after liver transplant usually benefit from combined liver and kidney transplant (CLKT). Others may need modified immunosuppressive regimens that minimize or avoid use of calcineurin inhibitors to preserve the remaining kidney function.
For assessment of kidney function, Equations that estimate GFR are most commonly used in daily practice. They have the advantage of being inexpensive and results are immediately available. Their disadvantage is that they rely on endogenous biomarkers, which are confounded by non-GFR determinants such as age, sex, muscle mass, drugs, certain chronic conditions, diet and presumably many more Creatinine, the most commonly used biomarker, depends heavily on muscle mass. Pre and intraoperative factors and postoperative complications were evaluated for their impact on development of AKI The preoperative factors MELD, SCr, Bilirubin and INR were highly associated with an increased risk for developing AKI requiring RRT for the post OLT complications, length of ICU stay was associated with the development of AKI Patients with a longer ventilation time and a higher amount of RPC transfusion were more likely to have AKI requiring RRT, whereas these parameters were not associated with milder forms of AKI.
