Determination of Specific Biomarkers of Angioneurotic Crisis
An observational study of Angioedema, run by University Hospital, Grenoble at 1 site in France.
Trial summary
Diagnosis of angioedema (AE) is difficult especially in emergency room. Two forms should be evoked: histaminic AE (allergic or not, which represent 95% of cases) and bradykinic AE (hereditary or acquired deficiency, with or without C1 Inhibitor) rarer but with more severe prognosis.

About this study
Diagnosis of angioedema (AE) is difficult especially in emergency room. Two forms should be evoked: histaminic AE (allergic or not, which represent 95% of cases) and bradykinic AE (hereditary or acquired deficiency, with or without C1 Inhibitor) rarer but with more severe prognosis. The distinction is based on clinical features (spontaneous crisis duration, presence of concomitant hives, atopic history...). Sometimes it could be difficult to make the difference. Nowadays, there is no biological marker of the crisis. The search for biomarkers could improve the diagnostic and therapeutic management of AE. Previous work has identified targets: D-dimer, C4, and VE-cadherin. We wanted to know the sensitivity and specificity of these markers.
We conducted a prospective study evaluating the D-dimer assays, complement and VE-cadherin during an episode of AE. Three groups of patients were tested: bradykinic AE (peripheral or abdominal attacks), histaminic AE, and abdominal pain (non-bradykinic and non-histaminic etiology) at the time (day 0) and at distance from the crisis (D7).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Diagnosis of angioedema (AE) is difficult especially in emergency room. Two forms should be evoked: histaminic AE (allergic or not, which represent 95% of cases) and bradykinic AE (hereditary or acquired deficiency, with or without C1 Inhibitor) rarer but with more severe prognosis. The distinction is based on clinical features (spontaneous crisis duration, presence of concomitant hives, atopic history...). Sometimes it could be difficult to make the difference. Nowadays, there is no biological marker of the crisis. The search for biomarkers could improve the diagnostic and therapeutic management of AE. Previous work has identified targets: D-dimer, C4, and VE-cadherin. We wanted to know the sensitivity and specificity of these markers.
We conducted a prospective study evaluating the D-dimer assays, complement and VE-cadherin during an episode of AE. Three groups of patients were tested: bradykinic AE (peripheral or abdominal attacks), histaminic AE, and abdominal pain (non-bradykinic and non-histaminic etiology) at the time (day 0) and at distance from the crisis (D7).

Questions about this trial
What is this clinical trial studying?
An observational study of Angioedema, run by University Hospital, Grenoble at 1 site in France.
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 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 Sep 2017. 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 France. 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?
VE CADHERIN SENSITIVITY AND SPECIFICITY (time frame: 7 DAYS). 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 NCT02833675, which also lists 23 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 29 Sep 2017.
