About this study

Official title: Is Adrenomedullin Upregulation Due to Apical Periodontitis Independent of Periodontal Disease?

The aim of the present study was to investigate the relationship between Apical periodontitis (AP) severity and inflammatory markers (IL-12, TNF-alpha), and Mid-Regional Pro Adrenomedullin (MR-proADM) in patients with AP. A total of 174 subjects were divided into three categories: AP group (n=82), Chronic periodontitis (CP) group (n=42), healthy control group (n=50). Blood samples were collected from all of the patients. Enzyme-linked immunosorbent assay was used to evaluate the samples.

Read the detailed description

Bone destruction in apical periodontitis (AP) depends on the microorganisms' efficiency to breach the host-epithelial barrier and various antimicrobial peptides. Mid-regional pro adrenomedullin (MR-proADM) is one such potent antimicrobial peptide, which plays a regulatory and stabilizing role among proinflammatory and anti-inflammatory cytokines. A broad range of cells and tissues produce MR-proADM such as adrenal medulla, kidney, lungs, and endothelial cells. MR-proADM was found to be present in circulation and in various biological fluids. It is reported to function both as a generalized hormone and locally affecting autocrine or paracrine mediator. Its plasma level is usually elevated in certain conditions such as heart failure, hypertensive situations, cerebro-vascular events, chronic kidney failure, diabetes mellitus, sepsis and periodontitis. Besides these, MR-proADM has drawn attention as it stimulates the proinflammatory cytokine IL-6 and suppresses cytokines, like TNF- α, for regulating inflammation, being a potent of inhibitor of apoptosis and stimulating angiogenesis in tumor cells. However, there is still a large information gap on MR-proADM. Despite all these effects, there is not enough information in the literature about the effect of MR-proADM on oral and dental health and its effectiveness in apical periodontitis. Whether AP can cause any alterations in the MR-proADM value is also unknown.

Therefore, the aim of this study is to investigate the relationship between AP severity and inflammatory markers (IL-12, TNF-alpha), and MR-proADM in patients with AP. In addition, the results will be compared with the results of healthy controls and patients with chronic periodontitis.

Questions about this trial

What is this clinical trial studying?

A study testing Apical periodontitis and Chronic periodontitis in people with Periapical Periodontitis, run by Istanbul Medipol University Hospital at 1 site in Turkey (Türkiye).

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 1 inclusion and 1 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 29 Aug 2023. 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 Turkey (Türkiye). 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?

Mid-Regional Pro Adrenomedullin levels (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Aug 2023.
