What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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
