Acute kidney failure is common in children in the Pediatric Intensive Care Unit (PICU). You are being asked to participate in this study because your child is being treated for kidney failure with continuous veno-venous hemofiltration (CVVH). CVVH is a continuous, gentle form of removing excess fluids and small wastes from the blood, similar to kidney dialysis (artificial kidney). It is an accepted therapy for temporary support of kidney failure. In some patients with acute kidney failure, beginning CVVH is followed by a temporary decrease of urine output. The reason why this happens is currently unknown. The purpose of this study is to determine why this happens.
Acute renal failure is common in children in the pediatric intensive care unit. Renal replacement therapies such as peritoneal dialysis (PD), intermittent hemodialysis (IHD), and continuous venovenous hemofiltration (CVVH) have been used in the management of acute renal failure. CVVH is becoming increasingly utilized in pediatric acute renal failure. However, in patients who have acute renal failure, the institution of CVVH is often followed by a progression to oliguria or anuria. The underlying pathophysiology of this change is unknown. We believe that this progression is influenced by changes in the renin-angiotensin axis, cytokine response, and other modifiers of renal hemodynamics. By serially measuring components of those systems, this study will attempt to elucidate the pathophysiology of the decreased urine output seen with institution of CVVH. Once this process is understood, future studies should focus on prevention and treatment of this complication.
The decrease in urine output seen after the initiation of CVVH is associated with increased angiotensin converting enzyme (ACE) levels, increased renin activity, increased angiotensin II levels, increased atrial naturetic peptide (ANP) levels, increased endothelin-1 levels, increased arginine vasopressin (AVP) levels, and alterations of cytokine levels and modulators of apoptosis.

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.
Conditions in which the KIDNEYS perform below the normal level in the ability to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal insufficiency can be classified by the degree of kidney damage (as measured by the level of PROTEINURIA) and reduction in GLOMERULAR FILTRATION RATE. The most severe form is KIDNEY FAILURE. Renal function may deteriorate slowly (RENAL INSUFFICIENCY, CHRONIC) or precipitously (RENAL INSUFFICIENCY, ACUTE).
Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.
A syndrome that is associated with microvascular diseases of the KIDNEY, such as RENAL CORTICAL NECROSIS. It is characterized by hemolytic anemia (ANEMIA, HEMOLYTIC); THROMBOCYTOPENIA; and ACUTE RENAL FAILURE.
A diuretic and renal diagnostic aid related to sorbitol. It has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity.
