Summary

The screening for latent tuberculosis infection (LTBI) prior to the onset of anti-tumor necrosis factor therapy, as well as a watchful monitoring during the treatment, is strongly recommended. Tuberculin skin test (TST), universally used for this purpose, lacks sensitivity and specificity. The novel screening tools, including QuantiFERON-TB Gold In-Tube (QFT-GIT), have shown a higher specificity compared to TST, but their feasibility in the setting of immunosuppression remains unclear. Aims of this study were to investigate the performance of QFT-GIT and its agreement with TST in patients awaiting anti-tumor necrosis factor (TNF) therapy, and to evaluate the usefulness of serial QFT-GIT during the treatment with biologics to assess whether dynamic changes in interferon (IFN)-gamma levels may be helpful in identifying reactivation of LTBI or cases of newly acquired tuberculosis.

Conditions

  • Inflammatory Rheumatic Diseases

Interventions

BIOLOGICAL

QuantiFERON-TB Gold In-Tube (QFT-GIT)

Patients were randomized to undergo, on the same day, TST and QFT-GIT by means of a randomization list to generate the order by which the 2 tests had to be executed. QFT-GIT was repeated after 3 and 6 months since TNF antagonist onset
