Reveal Kidney Stress Early. Drive Better Outcomes.

Acute Kidney Injury (AKI)

Acute kidney injury (AKI) is a syndrome that consists of an abrupt loss of kidney function. It affects more than 70% of intensive care units (ICU) patients1,2. In critical care settings, current diagnosis tools are lagging, so prevention is key. An early implementation of nephroprotective measures can indeed reduce the incidence of both moderate and severe stages of AKI.

What is Acute Kidney Injury?

Acute Kidney Injury is an abrupt loss of kidney function that develops within 7 days. It is currently diagnosed using serum creatinine and urine output. It is a frequent syndrome in the ICU, where patients show hemodynamic instability, present various comorbidities, and are exposed to nephrotoxic drugs which put them at risk of developing AKI.  

What is the Healthcare Burden of AKI?

Acute kidney injury is an increasing global challenge for patients, healthcare providers, and societies:  

  • 13.3 million new cases of AKI per year3
  • 74% of ICU patients develop AKI1,2
  • 42% of septic patients in ICUs have AKI4

AKI is associated with serious short and long-term complications, including longer hospital and ICU stays and increased mortality rates. AKI survivors are also at increased risk of developing chronic kidney disease (CKD) and cardiovascular complications. Greater severity, prolonged duration, and recurrent episodes of AKI amplify its overall impact. Also, when an acute kidney injury progresses to a chronic kidney disease, the patient's well-being, quality of life, and families are all impacted. 

Healthcare costs associated with AKI management are high and exceed those of common cancers.5 In the absence of successful therapies to treat AKI, prevention is paramount. Identifying patients at high-risk of AKI provides a window of treatment for the healthcare community. 

While tools already exist to diagnose AKI, serum creatinine levels and urine output are lagging indicators in critically ill patients, with low sensitivity and specificity.6 In this setting, AKI is therefore generally diagnosed late.

What is Our Solution for AKI?

bioMérieux has developed an assay that detects kidney stress when intervention can still make a difference. It is intended to be used in acutely ill patients in conjunction with clinical evaluation, to aid in identifying patients at risk for developing moderate or severe AKI within the following 12 hours.

With an early warning, healthcare providers can personalize medicine and confidently rule out patients from nephroprotective measures, or implement nephroprotective measures to improve patient outcomes and reduce costs7,8, and potentially reduce the development of new comorbidities.
