About this study
Official title: Evaluation of Corticosteroid as Modulators of Humeral and Cellular Immune Response in Open Heart Surgery in Egyptian Population
Cardiac surgery and cardiopulmonary bypass (CPB) initiate a whole-body systemic inflammatory response (SIRS) characterized by the activation of leukocytes, monocytes, and the complement cascade. Multiple mediators of the inflammatory process are released, including cytokines, endothelin, adhesion molecules, and oxygen free radicals. An exaggerated release of these mediators may contribute to numerous postoperative end-organ complications, including myocardial dysfunction, neurologic impairment, respiratory failure, altered renal and hepatic function, bleeding disorders, and multiple organ failure. Although most cardiac surgical patients do not experience major adverse events, it is likely that the inflammatory response impairs clinical recovery to some degree in all patients.
A large number of therapeutic strategies have been developed to attenuate the inflammatory reaction to CPB and thereby enhance recovery of the cardiac surgical patient. Intraoperative corticosteroid administration has been studied extensively as a primary pharmacologic anti-inflammatory treatment option.
Read the detailed description
Investigations have shown that clinical outcomes have been improved, worsened, or unaffected by the intraoperative administration of dexamethasone or methylprednisolone Limited data suggest that low-dose corticosteroids may be as effective as high-dose treatment in reducing complications but with fewer potential side effects MicroRNAs (miRNAs) are protein regulators that play an important role in a wide range of cellular functions. There is increasing evidence for the close relationship between miRNA expression, Th17 cell differentiation and disease pathology The miRNA, miR-155, which was the subject of this study, has a range of known biological functions, which include the induction of Toll like receptor (TLR) activation in monocytes /macrophages and the modulation of TLR signaling, facilitating pro-inflammatory cellular responses and initiating systemic inflammatory responses, as well as regulating Treg cell differentiation, maintenance, and function. The expression of this miRNA can be induced by inflammatory cytokines, such as tumor necrosis factor α (TNFα), that are released into the circulation in the initial stages of a systemic inflammatory response. In another study, demonstrated that miR-155 enhanced Treg and Th17 cell differentiation and Th17 cell function by targeting (suppressor of cytokine signaling 1) SOCS1.
In this study, the investigators will compare effect of low dose intra-operative corticosteroid (dexamethasone and methylprednisolone) as anti-inflammatory modulators through detection of T regulatory cells(Tregs) and IL-17 and correlate relation between Treg, IL-17 and micro RNA-155.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Cardiac surgery and cardiopulmonary bypass (CPB) initiate a whole-body systemic inflammatory response (SIRS) characterized by the activation of leukocytes, monocytes, and the complement cascade. Multiple mediators of the inflammatory process are released, including cytokines, endothelin, adhesion molecules, and oxygen free radicals. An exaggerated release of these mediators may contribute to numerous postoperative end-organ complications, including myocardial dysfunction, neurologic impairment, respiratory failure, altered renal and hepatic function, bleeding disorders, and multiple organ failure. Although most cardiac surgical patients do not experience major adverse events, it is likely that the inflammatory response impairs clinical recovery to some degree in all patients.

Intraoperative corticosteroid administration has been studied extensively as a primary pharmacologic anti-inflammatory treatment option.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing solumedrol and Dexamethasone phosphate in people with Systemic Inflammatory Response Syndrome, run by Assiut 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 2 inclusion and 4 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 14 Jun 2021. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
measure anti-inflammatory effect through detection T regulatory cell level by4 color flow cytometry analysis to quantify % of Tregs (CD4, CD25,FoxP3) (time frame: 72 hours post operative). 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 NCT03876041, which also lists 5 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 14 Jun 2021.
