About this study

Official title: Pilot Study of Endoscopic Ultrasound as an Early Diagnostic Tool for Evaluation of Suspected Primary Sclerosing Cholangitis

Primary sclerosing cholangitis (PSC) is a rare chronic cholestatic liver disease, typically affecting middle aged men and is frequently associated with inflammatory bowel disease. Establishing diagnosis in early stages of cholestatic hepatopathy is still a clinical challenge and based on invasive diagnostic procedures: endoscopic retrograde cholangiography (ERC) or percutaneous liver biopsy are needed when magnetic resonance cholangiopancreaticography remains inconclusive. As these procedures are associated with significant risks for the patient, the goal of this study is to evaluate, if endoscopic ultrasound (EUS) of the biliary tract is a useful diagnostic tool in suspected PSC.

Read the detailed description

Different parameters of the common bile duct (wall thickness and irregularity, irregularity of the common bile duct and enlarged lymph nodes) are measured in patients with cholestatic hepatopathy of unknown causes via endoscopic ultrasound (EUS).

This EUS of the CBD is performed from the bulbar position in the duodenum and at least 5 cm of bile duct had to be visualized to correctly analyze bile duct structure.

Further diagnostic work-up of these patients is performed following current guidelines, and definite diagnosis is compared with results of EUS parameters measured. Thus, diagnostic yield of EUS in patients with suspected PSC is further evaluated.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01556412
Study groupRoleWhat they receive
Chronic hepatopathy suspicious of PSCAll patients with chronic hepatopathy of unknown origin and a high risk of primary sclerosing cholangitis as the underlying disease for chronic hepatopathy. This group includes all patients with cholestatic hepatopathy (predominantly elevated gamma-glutamyltransferase and alkalic phosphatase) and positive ANCAs (Anti-neutrophil cytoplasmic antibodies) and/or inflammatory bowel disease in medical history. Other explanations of cholestatic hepatopathy (like pancreatic tumor or cholelithiasis) must not be apparent in patients eligible for this study. Furthermore, infection oder extrahepatic cholestasis already proven by laboratory results or percutaneous ultrasound, which make endoscopic retrograde cholangiography necessary, are exclusion criteria in this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Suspicion of PSC in endosonographic ultrasound

    Endosonographic ultrasound of the common bile duct

    Four different diagnostic parameters evaluated during endosonographic ultrasound are evaluated in predicting primary sclerosing cholangitis:

    • Wall thickening ≥ 1.5 mm
    • Irregular wall structure of the common bile duct
    • Irregular caliber of the common bile duct
    • Lymph nodes proven in the perihilar region of at least 10 mm diameter were defined as enlarged.

    With 2 of 4 criteria positive, patients were classified as suspected diagnostic PSC by means of EUS.

    Measured: From date of endosonographic ultrasound until the date of definite diagnosis of cholestatic hepatopathy, up to 3 months (participants will be followed as outclinic patients in our center for an expected average of 6 weeks until definite diagnosis)

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Sclerosing Cholangitis, run by Tischendorf, Jens, M.D. at 1 site in Germany.

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 21 Oct 2014. 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 Germany. 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?

Suspicion of PSC in endosonographic ultrasound (time frame: From date of endosonographic ultrasound until the date of definite diagnosis of cholestatic hepatopathy, up to 3 months (participants will be followed as outclinic patients in our center for an expected average of 6 weeks until definite diagnosis)). 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 NCT01556412, which also lists 3 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 21 Oct 2014.
