Analysis of Clinical Outcomes in Patients Undergoing Acute Dialysis Therapy at Intensive Care Units
Summary
Acute kidney injury is more frequent and the mortality rate would be as high as 50-60% when the renal replacement therapy was needed. Many studies about the timing of start and discontinuation of dialysis, dialysis dose, dialyzer, anticoagulation and dialysates were initiated but the results were still controversial. In addition, more new biomarkers were found to predict the outcome of acute kidney injury and these biomarkers may play an important role for the dilemma of aforementioned studies.
This observational prospective study has two objectives:
1. To find the predictors of outcome for the acute kidney injury with renal replacement therapy and determine the appropriate method.
2. To find the relationship between new biomarkers and acute kidney injury and determine whether it can be a factor for the monitor of the response of the renal replacement therapy.
Description
Background:
Acute kidney injury is more frequent than before and the incidence rate was about 35-50% in hospital. The mortality rate would be as high as 50-60% when the renal replacement therapy was needed. Many studies about the timing of start and discontinuation of dialysis, dialysis dose, dialyzer, anticoagulation and dialysates were initiated but the results were still controversial. In addition, more new biomarkers were found to predict the outcome of acute kidney injury and these biomarkers may play an important role for the dilemma of aforementioned studies
Objectives:
1. To find the predictors of outcome for the acute kidney injury with renal replacement therapy and determine the appropriate method of renal replacement therapy for acute kidney injury
2. To find the relationship between new biomarkers and acute kidney injury and determine whether it can be a factor for the monitor of the response of the renal replacement therapy.
Methods:
1. Study duration: 2010/01/01 to 2011/6/30
2. Patient eligibility : over 18 years-old and admitted to medical intensive care units of National Taiwan University Hospital
3. A prospective study to collect the parameters including underlying diseases, vital signs, biochemistry data, urine output, disease severity scores, dialysis timing, dialysis dose, dialyzer, anticoagulation agents
4. Collect serum and urine sample for biomarkers if patient agree
Statistics:
Normally distributed variables are expressed as means ± SDs. Statistical significance is set at P<0.05. All statistical analyses are performed with SAS statistical software. Comparisons between two groups are assessed with the student's unpaired t test and Mann-Whitney test. Differences between more than two groups are analyzed by ANOVA (ANOVA) using one-way ANOVA. Survival analyses are made with the Kaplan-Meier survival curve and the Cox proportional hazard model.

Medical and Biotech [MESH] Definitions
Acute Kidney Injury
Abrupt reduction in kidney function defined as an absolute increase in serum CREATININE of more than or equal to 0.3. mg/dl, a percentage increase in serum creatinine of more than or equal to 50%, or a reduction in urine output. Acute kidney injury encompasses the entire spectrum of the syndrome including acute kidney failure; ACUTE KIDNEY TUBULAR NECROSIS; and other less severe conditions.
Kidney Tubular Necrosis, Acute
Acute kidney failure resulting from destruction of EPITHELIAL CELLS of the KIDNEY TUBULES. It is commonly attributed to exposure to toxic agents or renal ISCHEMIA following severe TRAUMA.
Kidney Failure
A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.
Kidney Papillary Necrosis
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
Renal Insufficiency, Acute
Conditions in which the function of KIDNEYS deteriorates suddenly in a matter of days or even hours. It is characterized by the sudden drop in GLOMERULAR FILTRATION RATE; (GMR). The most severe stage is when the GFR drops below 15 ml per min (ACUTE KIDNEY FAILURE).
