An observational study of Colorectal Disorders and Colorectal Neoplasms, run by University Hospital of Patras at 1 site in Greece.
Trial summary
Butyrylcholinesterase (BChE) is an α-glycoprotein synthesized in the liver. BchE's serum level decreases in many clinical conditions such as acute and chronic liver damage, inflammation, injury and infections, and malnutrition. Read more about this study

About this study
Butyrylcholinesterase (BChE) is an α-glycoprotein synthesized in the liver. BchE's serum level decreases in many clinical conditions such as acute and chronic liver damage, inflammation, injury and infections, and malnutrition. The Investigators prospectively evaluate patients undergoing elective procedures for colorectal diseases. Blood samples are collected preoperatively (at day 0), post-operatively in the recovery room (day 1), and on the subsequent four days (days 2, 3, 4, and 5) for assessment of BChE, C-reactive protein, and white blood cell concentrations. The same surgical team operates all patients and is blinded to the study. Patients are monitored for post-operative infection by using standard laboratory and clinical methods. If surgical site infection (SSI) is suspected the wound is swabbed and empirical antibiotics are started. The aim of the current trial is to study whether BChE is a reliable marker for the presence of SSI in patients undergoing colorectal surgery.
Read the detailed description
Butyrylcholinesterase (BChE or BuChE) is a cholinesterase enzyme that is very similar to acetylcholinesterase (AChE). However, though the role and function of AChE in the human body are widely studied and known, BChE is usually referred to as an 'orphan enzyme' because its specific physiological role is still under question. Lastly, it has been found, however, that BChE has more specific functions than it was previously believed and acetylcholine (ACh), which will be further analyzed, can affect the immune system and is associated with inflammation-related events. Butyrylcholinesterase is an enzyme that for several years was not considered to have a specific physiological role but lately, it has been observed that plays an important role in inflammation as acetylcholine is a major player of the 'cholinergic anti-inflammatory pathway' inhibiting inflammation. It has been proved that BChE activity can be affected by several diseases. Low-grade inflammation is associated with an increase of its levels whereas a reduction is observed when systemic inflammation is present. However, future research is needed in order to be widely used in clinical practice as a biomarker for several pathological conditions involving inflammation. Therefore, the aim of this study is to present information about butyrylcholinesterase, its function, and its role in the human body, highlighting its association with inflammation analyzing past studies about this subject. The Investigators prospectively evaluate patients undergoing elective procedures for colorectal diseases. Blood samples are collected preoperatively (at day 0), post-operatively in the recovery room (day 1), and on the subsequent four days (days 2, 3, 4, and 5) for assessment of BChE, C-reactive protein, and white blood cell concentrations. The same surgical team operates all patients and is blinded to the study. Patients are monitored for post-operative infection by using standard laboratory and clinical methods. If surgical site infection (SSI) is suspected the wound is swabbed and empirical antibiotics are started. The aim of the current trial is to study whether BChE is a reliable marker for the presence of SSI in patients undergoing colorectal surgery.

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?
Value of Butyrylcholinesterase as a Marker of Surgical Site Infection Following Surgery for Colorectal Diseases (time frame: November 6th 2019 to March 1st 2023). 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 NCT04748744, which also lists 2 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 15 Jun 2023.
