Trial for the Diagnosis of Sarcoidosis (GRANULOMA)
|ClinicalTrials.gov Identifier: NCT00872612|
Recruitment Status : Completed
First Posted : March 31, 2009
Last Update Posted : December 7, 2015
This randomized study investigates two different diagnostic strategies for patients with suspected pulmonary sarcoidosis stage I/II.
The objective is to assess the role of endosonography (EBUS/ EUS - FNA) in demonstrating non-caseating granulomas in comparison with conventional bronchoscopy (TBLB + EBB).
Also the researchers investigate the additional value of BAL, in relation to endosonography and conventional bronchoscopy (TBLB + EBB), in diagnosing sarcoidosis.
Thirdly the researchers aim to assess the rate of complications in both the endosonography and conventional bronchoscopic workup.
|Condition or disease||Intervention/treatment||Phase|
|Sarcoidosis||Procedure: EUS-FNA/EBUS-TBNA + BAL Procedure: EBB + TBLB + BAL||Phase 3|
Sarcoidosis is the most prevalent interstitial lung disease in Western-Europe and the US. The disease is most prevalent in young adults. To set the final diagnosis of sarcoidosis, the following parameters need to be present:
- A clinical and radiological suspicion of sarcoidosis stage I/II.
- A tissue diagnosis of disease-specific non-caseating granulomas.
- Exclusion of possible alternative diagnoses as lung cancer or tuberculosis.
Nowadays, a bronchoscopy with lung biopsies is advised to set a tissue diagnosis of sarcoidosis. However, these biopsies are only diagnostic in 70% of the procedures and they are associated with a 3% risk of coughing up blood and a 4% risk of a lung collapse.
Since recently, a new diagnostic procedure has come available. This procedure, endo-sonography, makes it possible to biopsy lymph nodes in the chest under direct visualization and has a diagnostic accuracy of 85%. The associated risk of complications appears to be small (<1%)
We consider the current standard for the diagnostics of sarcoidosis to be outdated, considering the clinical availability of endo-sonography. We expect that endo-sonography is more frequent diagnostic for a tissue diagnosis of sarcoidosis.
Also we hypothesize that this technique is safer and more preferred by patients.

Procedure: EUS-FNA/EBUS-TBNA + BAL
EUS-FNA = Endoscopic Ultrasound guided fine needle aspiration of mediastinal lymph nodes.
EBUS-TBNA = Endobronchial Ultrasound guided transbronchial needle aspiration of mediastinal and hilar lymph nodes.
BAL = bronchoalveolar lavage
Active Comparator: B
Conventional bronchoscopy arm
Procedure: EBB + TBLB + BAL
EBB = Endobronchial biopsy TBLB = Transbronchial biopsy BAL = Bronchoalveolar lavage
