The Utility of Ischemia Modified Albumin (IMA) in Sepsis

2014-08-27 03:39:36 | BioPortfolio


The purpose of this study is to determine if levels of ischemia modified albumin (IMA) in blood are elevated in patients with suspected infection and are predictive of severity of illness in patients with sepsis.

In order to compare subjects with infection to those without infection who are representative of the ED population at each site, a group of non-infected control patients will be enrolled. Each hospital will enroll subjects with age (by decade) and sex matched controls to reflect the population of subjects suspected of infection.


Sepsis is an unconquered challenge in medicine, affecting people of all ages and demographics. Severe sepsis affects approximately 751,000 patients in the United States per annum, with healthcare costs approaching $16.7 billion dollars a year. Mortality from severe sepsis and septic shock approaches 30 - 70 % with 215,000 deaths annually. Thus, sepsis is a disease with healthcare dollars and mortality rates approaching those of heart disease and cancer.

Identifying patients with sepsis, and in particular hypoperfusion, is a challenge to the clinician. A variety of clinical and laboratory findings are helpful, but there is no single test to identify sepsis or assess its severity.

Ischemia and reactive oxygen species play a significant role in the pathogenesis of sepsis. Moreover, there is evidence to suggest that septic shock results in dysfunction of autoregulatory mechanisms and misdistribution of blood flow, precipitating both regional and global ischemia. A method that can help rapidly assess hypoperfusion would be clinically useful. Ischemia modified albumin (IMA) is a potential marker for ischemia in acute coronary syndrome patients; thus, it is hypothesized that IMA may be also useful as a prognostic biomarker for clinical identification of infection and the severity of illness in patients with sepsis.

Medical and Biotech [MESH] Definitions

Systemic inflammatory response syndrome with a proven or suspected infectious etiology. When sepsis is associated with organ dysfunction distant from the site of infection, it is called severe sepsis. When sepsis is accompanied by HYPOTENSION despite adequate fluid infusion, it is called SEPTIC SHOCK.

Acute neurological dysfunction during severe SEPSIS in the absence of direct brain infection characterized by systemic inflammation and BLOOD BRAIN BARRIER perturbation.

Blood infection that occurs in an infant younger than 90 days old. Early-onset sepsis is seen in the first week of life and most often appears within 24 hours of birth. Late-onset occurs after 1 week and before 3 months of age.

Test to determine the presence of blood infection (e.g. SEPSIS; BACTEREMIA).

Sepsis associated with HYPOTENSION or hypoperfusion despite adequate fluid resuscitation. Perfusion abnormalities may include, but are not limited to LACTIC ACIDOSIS; OLIGURIA; or acute alteration in mental status.
