Primary Outcome Measures:
  • Concordance between the Quantiferon-TB Gold assay and the tuberculin skin test
  • Correlation of the test results to the patient's risk of latent TB infection

Secondary Outcome Measures:
  • Factors associated with discordance between the TST and the QFT-G test
  • Frequency of anergy in this patient population

Detailed Description:
Tuberculosis (TB) is an important cause of morbidity and mortality in organ transplant recipients. Although the tuberculin skin test (TST) is recommended for screening of latent tuberculosis infection (LTBI) in all candidates for liver transplantation, the performance of the TST in this setting is less than optimal, due to a lack of specificity and a lack of sensitivity in a population that is relatively immunocompromised. Recently, a new test named QuantiFERON-TB Gold (QFT-G) has been approved for the diagnosis of LTBI. QFT-G is expected to be more specific than TST. However, there are no studies defining the performance of QFT-G in a population of patients on a waiting list for liver transplantation. We plan to estimate the usefulness of the QFT-G test for the diagnosis of LTBI in a cohort of patients with end-stage liver disease. We hypothesize that the QFT-G test will correlate better with the risk of LTBI.
