Can a common blood thinner be safe for ICU patients with liver issues?
NCT ID NCT07751874
First seen Aug 07, 2026 · Last updated Sep 21, 2026 · Updated 1 time
Summary
This study looks at whether a blood-thinning method called citrate anticoagulation is safe and practical for critically ill patients with acute kidney injury who may not process citrate normally. It follows 50 ICU patients who need kidney replacement therapy and are at risk for citrate buildup. The goal is to see how often citrate toxicity occurs and whether this approach can be used without causing harm.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- continuous renal replacement therapy with regional citrate anticoagulation
- What this could lead to
- If successful, this could support the safe use of citrate anticoagulation in patients with impaired citrate metabolism, potentially expanding treatment options for acute kidney injury in the ICU.
- What could go wrong
- This is an observational study with a small sample size, and it does not compare against other treatments. The risk of citrate toxicity remains a concern, and results may not apply broadly.

Inclusion Criteria: * Need for renal replacement therapy in the ICU with any of the following criteria: * anticipation of severely impaired citrate metabolism (serum lactate ≥ 5 mmol/l in patients with shock or requirement of a dextrose drip to prevent hypoglycemia or spontaneous INR \> 3 and/or requirement of fresh frozen plasma to maintain INR \< 3 in patients with cirrhosis or acute liver failure or acute on chronic liver failure) * development of citrate toxicity under CRRT with RCA due to worsening citrate metabolism Exclusion Criteria: * Pregnancy * A known hypersensitivity to citrate compounds * Refusal of informed consent
