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
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 This study
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 Results may not be published yet.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.

Summary

This study tested whether a blood sample can predict how severe COVID-19 will become in kidney transplant patients with mild to moderate symptoms. Researchers measured a protein called IL-6 after stimulating the blood sample. They followed 52 patients to see if IL-6 levels were linked to worsening illness, such as needing intensive care. The goal is to find early warning signs to improve patient care.

What this could mean

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

What this could lead to
If successful, this could help doctors identify which kidney transplant patients with COVID-19 are at higher risk of severe illness, allowing earlier intervention.
What could go wrong
This is a small, observational study (52 participants) that only looks at biomarkers, not a treatment. The findings may not apply to all patients or lead to direct clinical changes.
