About This Study

Summary

Although medications like antibiotics are important weapons for fighting illness, they can have unwanted side effects. Clinicians use various tools, including laboratory tests, to monitor whether the treatment a patient receives is both effective and safe for them. For example, two antibiotics used to treat antimicrobial-resistant gram-negative infections (meropenem and cefepime) can decrease kidney function in some patients.

The "gold standard" method for assessing kidney function involves using a marker compound (iohexol), but some patients have allergic reactions to iohexol. As a potential alternative, the OPTIMIZE-GNI study is investigating cystatin (Cys-C), a normal protein produced by cells in the body and released into the bloodstream. The goal of the OPTIMIZE-GNI study is to show that, in terms of estimating kidney function, using Cys-C is at least as accurate as using iohexol. Having accurate information about patients’ kidney function helps physicians to tailor their treatment plans to minimize side effects and maximize therapeutic benefit.

To be included in OPTIMIZE-GNI, participants must be / have

  • Adult (18 years or older) ICU patient
  • Documented or suspected antimicrobial-resistant gram-negative infection currently being treated with meropenem or cefepime

To be included in OPTIMIZE-GNI, participants must not be / have

  • Hypersensitivity or allergic reaction to iohexol, any other contrast agent, or iodine
  • Prior history of severe cutaneous reactions to iohexol, any contrast agents, or iodine
  • Received iohexol within 1 day prior to enrollment OR expected to receive iohexol for clinical care during the study
  • Major surgery within 2 days prior to enrollment
