This Article [5] [1] Although the prevalence of TB in the United States has decreased approximately 63% in the past 2 decades (3.2 TB cases per 100,000 people in 201234), current diagnostic recommendations conclude that IGRAs permit several advantages over the TST in clinical practice.7,12,23,35⇓⇓⇓–39 Because IGRAs have specific antigens that target M. tuberculosis, they do not react with common NTM23,39 or BCG vaccine strains12,36 and do not produce an immunologic “boost.”40,41 Although there are additional costs, the administrative and laboratory analytical techniques for IGRAs follow a standard, objective protocol and provide results within 24 hours, enabling the identification and management of patients with LTBI from hard-to-reach groups.42, IGRAs have been recommended as tests in the diagnosis of M. tuberculosis infection in several different clinical scenarios.37,38,43 IGRAs should be administered in adults, including BCG-vaccinated individuals37,38 or people with immunocompromising conditions.23,44 They should also be administered in situations where the TST has a positive result or in hard-to-reach population groups.42,45 In addition, IGRAs may be considered in children >5 years old who have a suspected LTBI, whether from a high-incidence country or with confirmed household contacts.42,46 However, another physician with expertise in the diagnostics and management of TB should review any clinical case where a child with an immunocompromising condition presents with a suspected LTBI.42, However, there may arise clinical scenarios in which IGRA diagnostic measures conclude a qualitative result as indeterminate or a quantitative value in the borderline zone after testing patients with a suspected diagnosis of LTBI.

The 12-dose regimen of INH and rifapentine (RPT), or a once weekly dose for 3 months, can be prescribed for HIV-negative patients >12 years old.58,68 Because RPT is a pharmacological derivative of RIF, clinical trials have demonstrated that although adverse effects are similar to monotherapy INH or RIF, there are fewer drug–drug interactions with RPT.63 One multicenter randomized clinical trial concluded that participants who followed this 12-dose regimen by DOT demonstrated increased compliance to treatment and equivalent therapeutic outcomes when compared with those taking INH monotherapy.69,70 Key diagnostic and treatment recommendations for practice according to the Strength of Recommendations Taxonomy are presented in Table 4.71.
