About this study
Official title: Persistent Inflammation, Immunosuppression and Catabolism Syndrome (PICS): A New Horizon for Surgical Critical Care Subtitle. Kidney Response to Sepsis Affects Angiogenic Balance and Likelihood of CCI and PICS
This study investigates the mechanism by which kidney dysfunction perpetuates inflammation, immunosuppression, and catabolism (PICS) in chronic critical illness. The investigators will test the hypothesis that persistent kidney dysfunction in sepsis associated by chronic critical illness contributes to decreased survival through the development of PICS. In chronic critical illness, the persistence of the inflammatory state may lead to capillary rarefication in the kidney causing accelerated chronic kidney disease. Progression of chronic kidney disease during chronic critical illness can drive PICS. Indeed, many of the features of chronic critical illness are consistent with the protein-energy malnutrition and muscle wasting associated with chronic kidney disease. Thus, the kidney can play a contributory role in chronic critical illness and PICS.
Read the detailed description
The main goal of this project is to measure kidney filtration function at day 14 or the day of discharge from hospital (whichever occurs first), in order to determine the presence and magnitude of persistent kidney dysfunction after sepsis episode and to longitudinally assess further decline of kidney function at one year follow-up. The measure of the glomerular filtration rate (GRF) in patients with chronic critical illness and controls (sepsis patients discharged from ICU before day 14) will be used to determine to what degree of kidney dysfunction contributes to decreased survival and increase in chronic kidney disease at year one after sepsis onset.
GFR assessment will be determined at approximately day 14 or approximately at the day of discharge from the ICU and at the one-year follow-up:
- Determine GFR by Iohexol clearance and/or
- Estimated GFR by urea concentration and creatinine clearance
- Estimated GFR using calculations with serum creatinine

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GFR by IohexolDiagnostic test
Also called omnipaque
Participants may receive a normal saline dilution of Iohexol 0.5-1 ml given by IV push. Blood or urine will be collected and measured to determine glomerular filtration rate measurements. This test will be repeated in one year.
Urine CollectionDiagnostic test
Both groups of sepsis participants will have urine collected for at least 4 hours to as long as 24 hours or more. The urine volume determined and a sample sent to the lab for determination of creatinine and urea concentration. This test will be repeated in one year.
Blood samplesDiagnostic test
Both groups of sepsis participants will provide peripheral blood samples to the research staff. The samples will be sent to the laboratory for serum creatinine results. This test will be repeated in one year.
| Study group | Role | What they receive |
|---|---|---|
| Inhospital group at day 14 | Experimental | This group of sepsis participants remain hospitalized at day 14. GFR assessment is performed at inpatient day 14 and again at 1 year follow up. Receives: Diagnostic Test: GFR by Iohexol; Diagnostic Test: Urine Collection; Diagnostic Test: Blood samples |
| Discharged prior to 14 days | Active comparator | The group of patients were discharged before 14 days. GFR assessment at time of discharge and again at 1 year follow up. Receives: Diagnostic Test: GFR by Iohexol; Diagnostic Test: Urine Collection; Diagnostic Test: Blood samples |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

The investigators will test the hypothesis that persistent kidney dysfunction in sepsis associated by chronic critical illness contributes to decreased survival through the development of PICS.

Progression of chronic kidney disease during chronic critical illness can drive PICS.

What is this clinical trial studying?
A study testing GFR by Iohexol, Urine Collection and Blood samples in people with Sepsis, run by University of Florida at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Delta Curve Between Calculated GFR and GFR Measured by Iohexol at Baseline (time frame: For Arm 1 baseline is measured GFR at 14 days inhospital with sepsis or sepsis diagnosis. For Arm 2 baseline is measured GFR at discharge date prior to day 14 of hospitalizaton with sepsis or sepsis diagnosis.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02276066, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2024.
