About this study
Official title: A Prospective Observational Study of Usefulness of a T Cell-based Assay for Latent Tuberculosis Infection in Hematopoietic Stem Cell Transplant Recipients
The aim of this study is to estimate the usefulness of a T cell-based assay (i.e. Quantiferon-Gold In-Tube assay) for diagnosis of latent tuberculosis infection (LTBI) in bone marrow transplant recipients. For this purpose, the investigators enrolled bone marrow transplant recipients and observed the developement of tuberculosis after the transplantation.
Read the detailed description
All adult bone marrow transplant recipients admitted to Asan Medical Center will be enrolled.
Quantiferon-Gold In-Tube assay will be performed.
Isoniazid prophylaxis will be given only to patients with clinical risk factors (i.e. recent contact with active pulmonary TB patient or inadequate treatment history with abnormal CXR). However, isoniazid prophylaxis will be not given based on positive TST or positive Quantiferon-Gold In-Tube assay.

Where is the study taking place?
The record lists 1 site in South Korea. 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?
development of tuberculosis (time frame: after transplantation). 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 NCT01021124, 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 18 Jul 2013; AzTrials last refreshed its copy on 6 Nov 2026.
