Incidence, risk factors for active tuberculosis infection and changes of IGRA in patients with Takayasu arteritis : a prospective cohort study

There is limited evidence to support the association between tuberculosis (TB) and the occurrence of Takayasu arteritis (TAK). To investigate the incidence of active TB (ATB) in TAK and explore the impact of anti-rheumatic therapy on the occurrence of ATB or reactivation of Latent TB infection (LTBI) and their effect on interferon-γ release assay (IGRA) results, we conducted a prospective study based on the Chinese Registry for Systemic Vasculitis cohort. The standard incidence ratio (SIR) was calculated and stratified by age. Kaplan-Meier analysis was used to determine the effect of variables on ATB or LTBI reactivation in patients with TAK. Data from 825 patients with TAK in the registry were analysed. During a median follow-up of 5 years, 5 patients developed ATB with a crude incidence of 154 (95%CI:57-381) person-years/100,000. The SIR was 5.59 (95%CI:1.81-13.04). Glucocorticoids and conventional disease-modifying anti-rheumatic drugs (cDMARDs) did not increase the risk of ATB or LTBI reactivation (P > 0.05). However, the use of tumour necrosis factor inhibitor (TNFi) increased the risk of ATB in patients with LTBI (P < 0.001). Furthermore, the value of the IGRA assay decreased after treatment (P < 0.05). In conclusion, the incidence of TB infection is markedly increased in patients with TAK and patients with TAK are at high risk of developing ATB. Treatment with glucocorticoids and cDMARDs does not significantly increase the risk for ATB in patients with TAK. Moreover, IGRA may have limited effectiveness in monitoring ATB infection or LTBI reactivation in patients with TAK.
