Bicarbonate and Lipocalin in Systemic Inflammatory Response Syndrome (SIRS) Study - Full Text View

Sponsor:	Austin Health
Information provided by:	Austin Health
ClinicalTrials.gov Identifier:	NCT00706771

Purpose

The investigators will determine the efficacy of intravenous sodium bicarbonate in reducing progression to overt acute renal failure in patients with low urine output, the systemic inflammatory response syndrome, and early acute renal impairment as defined by a new and experimental test of renal function, serum neutrophil gelatinase-associated lipocalin (NGAL).

Detailed Description:

The investigators hypothesise:

In patients with SIRS (including the subsets of patients with greater illness severity, such as severe sepsis and septic shock), sodium bicarbonate will delay or avert the development of acute renal failure (RIFLE class I, F, L or E).
In patients with SIRS (including the subsets of patients with greater illness severity, such as severe sepsis and septic shock), serum NGAL is a sensitive and specific predictor of the subsequent development of acute renal failure (RIFLE class I, F, L or E).
Serum NGAL can accurately identify patients with SIRS who will gain the greatest benefit from an intervention capable of delaying or averting the progression of early renal impairment to acute renal failure.
Changes in serum NGAL with and without treatment with sodium bicarbonate are more predictive of subsequent clinical course at an earlier time point than are conventionally measured markers of renal function (serum creatinine, serum urea, calculated glomerular filtration rate) and other experimental markers of renal function (urine IL-18 and NGAL, serum or urine cystatin C).

To test these hypotheses the investigators have designed a protocol that simultaneously tests both NGAL as a diagnostic strategy and sodium bicarbonate as a therapeutic intervention.
