Interferon Gamma Release Assays (IGRA) Testing Versus Tuberculin Skin Test in Renal Transplant Recipients

Interferon gamma release assays (IGRA) have been shown to be more specific and sensitive for the detection of tuberculosis (latent or active infection) than the tuberculin skin test (TST) in immunocompetent individuals. However, very little data are available concerning the relative performance of IGRA and TST in immunosuppressed individuals from other causes than HIV.

The investigators hypothesize that IGRAs would be more sensitive and specific than the TST in a group of renal transplant recipients under chronic immunosuppressive treatment for detecting latent tuberculosis infection.

Primary Outcome Measures:
  • Agreement between results of QuantiFERON-Gold-in-tube and probability of latent tuberculosis infection [ Time Frame: Up to 3 years ]
    Agreement between probability of latent tuberculosis infection - established on the basis of a questionnaire and chest X-ray - and results of QuantiFERON-Gold-in-tube is computed

  • Agreement between results of T-SPOT.TB and probability of latent tuberculosis infection [ Time Frame: Up to 3 years ]
    Agreement between probability of latent tuberculosis infection - established on the basis of a questionnaire and chest X-ray - and result of T-SPOT.TB is computed

Secondary Outcome Measures:
  • Agreement between results of IGRA tests and TST in renal transplant recipients [ Time Frame: Up to 3 years ]
    Agreement between results of IGRA testing and between each IGRA test and TST will be determined by computing kappa values

Renal transplant recipients
Inclusion criteria: All renal transplant recipients followed by the Division of Nephrology aged above 18 years, and having accepted study protocol after informed consent

Detailed Description:

In a recent study (Triverio PA et al. "Interferon-gamma release assays versus tuberculin skin testing for detection of latent tuberculosis in haemodialysis patients". Nephrol Dial Transplant 2009; 24: 1952-6), the investigators had compared 2 IGRAs (T-SPOT.TB and Quantiferon Gold) with the TST and shown that one IGRA was clearly more sensitive than the TST but that both tests had a very low sensitivity for detecting prior TB.

This study applies the same protocol to renal transplant recipients undergoing routine annual check-up visits: questionnaire with detailed collection of risk factors for latent tuberculosis infection (LTBI), history of prior contact with tuberculosis (TB), BCG (Bacille of Calmette and Guerin vaccine), prior TB or LTBI, treatment for TB or LTBI, analysis of chest X-ray for signs of prior TB, on-going treatment, level of immunosuppression (CD4 lymphocytes), simultaneous blood sampling for T-SPOT.TB and Quantiferon Gold, and tuberculin skin testing.
