About this study
Official title: C-Reactive Protein / Albumin Ratio as a Predictive Inflammatory Marker for Postoperative Systemic Inflammatory Response Syndrome and/or Sepsis in Polytraumatized Patients in ICU
The goal of this observational study is to determine the value of CRP/Albumin Ratio as an inflammatory marker for predicting the development of postoperative Systemic Inflammatory Response Syndrome and/or Sepsis in polytraumatized patients admitted to Intensive care unit.
The main question it aims to answer is whether CRP/Albumin Ratio can be used as predictive inflammatory marker for postoperative Systemic Inflammatory Response Syndrome and/or Sepsis or not.
Read the detailed description
The development of postoperative Systemic Inflammatory Response Syndrome (SIRS) or Sepsis is a very serious complication that has been associated with high morbidity, mortality, and increased length of inpatient stay.
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection.
As surgical interventions lead to well-understood metabolic, neuroendocrine, and immune responses, the stress responses to surgery contribute to increased postoperative complications mostly caused by increased levels of Pro-inflammatory cytokines in response to surgical injury, which leads to changes of circulating acute phase proteins, such as albumin and C-reactive protein (CRP).
The CRP to albumin ratio (CAR) is a new index calculated by dividing CRP by the albumin level. It has been assumed to have predictive value in determining morbidity and mortality in many critical diseases.

Questions about this trial
What is this clinical trial studying?
An observational study of Crp, run by Ain Shams University at 1 site in Egypt.
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 5 inclusion and 5 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 2 Apr 2025. 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 Egypt. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Evaluate the relation of CRP/ albumin ratio to the prediction of postoperative SIRS or sepsis in polytrauma patients. (time frame: The patients will be evaluated for 5 days postoperatively). 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 NCT06050759, which also lists 9 linked publications.
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 2 Apr 2025.
