Iron deficiency hidden by inflammation: a new test may see through it

NCT ID NCT07739524

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 explores whether a blood test can accurately detect iron deficiency in hospitalized elderly patients who have inflammation, a condition that often masks true iron levels. Researchers will analyze blood samples from patients over 75 with high inflammation to develop a model that predicts iron status once inflammation subsides. The goal is to help doctors distinguish between true iron deficiency and anemia caused by inflammation, leading to better and faster care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Analysis of blood samples for iron-related biomarkers
What this could lead to
If successful, this could lead to a simple blood test that accurately identifies iron deficiency in elderly patients during inflammation, improving treatment decisions and reducing delays.
What could go wrong
This is an observational study, so it won't directly test a treatment. The predictive model may not be accurate enough for widespread use, and results may not apply to all elderly patients.

Inclusion Criteria: 1. Age ≥ 75 years. 2. Hospitalization with CRP \> 50 mg/L at admission. 3. Non-opposition expressed by patient or legally authorized representative Exclusion Criteria: 1. Advanced chronic kidney disease (estimated glomerular filtration rate \< 30 mL/min/1.73 m²) or chronic dialysis. 2. Severe hepatic impairment (Child-Pugh score B or C). 3. Severe hematological disorders (active hematologic malignancy or known myelodysplastic syndrome) or known iron metabolism disorders that may bias the study results (e.g., thalassemia, advanced hemochromatosis). 4. Hemoglobin \< 9g/L 5. Treatment with intravenous iron within 12 weeks or oral iron within 4 weeks prior to enrollment. 6. Blood transfusion within 3 months prior to enrollment 7.
