Etiology, Epidemiology and Prognostics of Acute Kidney Injury (AKI)

Fudan University

Status: Completed

Conditions: Nutrition Disorders; Renal Failure

Study type: Observational

Funder types: Other

Identifiers

NCT00953992

KY2009-107

Details and patient eligibility

About

• To investigate the etiology, epidemiology and prognostic factors of acute kidney injury.
• To find out risk factors that relate with the prognosis of acute kidney injury,focusing on inflammation, oxidative stress and nutritional status.
• To study on the relationship between gene polymorphism and prognosis of acute kidney injury.

Full description

1. to investigate the relationship between preexisting malnutrition and adverse outcomes in patients with AKI

   • Several nutritional assessment methods such as anthropometric, clinical and biochemical evaluations have been used; however, no single indicator is considered to be a "gold standard."

2. to evaluate the association of serum nutritional variables and prognosis of acute kidney injury

3. Given the different half-lives of serum nutritional markers, we hypothesized that the utility of serum nutritional variables as prognostic predictors may differ in early death (<7 days) and late death (>7 days, <28 days) patients.
