Finally, our results neither support nor refute the idea that a positive IGRA result, in the absence of treatment for LTBI, is associated with a higher risk of reactivation of LTBI, compared with a positive tuberculin skin test result alone.

What is LTBI in healthcare?
Latent tuberculosis infection (LTBI) is the presence of M. tuberculosis organisms (tubercle bacilli) without symptoms or radiographic or bacteriologic evidence of TB disease. Approximately 90-95% of those infected are able to mount an immune response that halts the progression from LTBI to TB disease. However, because prevention of TB has major public health implications, the Centers for Disease Control and Prevention (CDC) and the United States Preventive Services Task Force (USPSTF) recommend testing populations that are at increased risk for TB infection and treating those for whom TB disease has been ruled out. Health care providers must communicate the risks and benefits of treatment to their patients and encourage adherence and treatment completion.

What is the cause of TB?
Tuberculosis (TB) is caused by bacteria called Mycobacterium tuberculosis (M. tuberculosis). The bacteria, or germ, usually attack the lungs. TB germs can attack any part of the body, such as the kidney, spine, or brain. There is good news. People with TB can be treated if they seek medical help.
Is TB worse among minorities?
While the number of TB cases in the United States has gone down, TB still has worse effects among racial and ethnic minorities. This is because certain minority groups are more likely to have TB risk factors that can increase the chance of developing the disease (see page 8). This booklet answers common questions about TB.
How does TB spread?
The TB germs are spread into the air when a person with infectious TB disease of the lungs or throat coughs, speaks, or sings. People nearby may breathe in these TB germs and become infected. When a person breathes in TB germs, the TB germs can settle in the lungs and begin to grow.

Can TB be inactive?
In most people who breathe in TB germs and become infected, the body is able to fight the TB germs to stop them from growing. The TB germs become inactive, but they remain alive in the body and can wake up and become active later. This is called latent TB infection, or LTBI for short. People with LTBI.

What is LTBI treatment?
Treatment for latent tuberculosis infection (LTBI) is of particular concern in patients with inflammatory bowel disease (IBD) initiating biologic therapies to prevent tuberculosis (TB) reactivation. This study aimed to evaluate the effectiveness of LTBI treatment in IBD patients receiving biologic therapy.
When did IBD patients receive biologic therapy?
There was a retrospective review of all IBD patients diagnosed with LTBI following a tuberculin skin test (TST) and/or interferon gamma release assay (IGRA) and who received biologic therapy between 2002 and 2016. The primary outcome was tuberculosis reactivation after completion of LTBI treatment.
What are the immunologic therapies for UC?
The treatment of inflammatory bowel diseases (IBD), such as ulcerative colitis (UC) and Crohn’s Disease (CD), was revolutionized by the development of targeted immunologic therapies (“biologics”) against tumor necrosis factor alpha (TNF-α), integrins, and interleukins. 1, 2 One significant risk of using these newer therapies is an increased risk of infection; specifically, reactivation of latent tuberculosis infections (LTBI) in patients on biologic medications. 3–5 TNF-α has a role in recruiting inflammatory cells to sites of infection, enhancing phagocytosis, and aids in the development and maintenance of granulomas. 6–8 Hence, the impairment of these immune pathways increases the risk of reactivation of LTBI in patients taking anti-TNF-α agents. 6–8 The risk of LTBI reactivation in patients taking anti-integrin medications does not seem to carry the same risk as patients taking anti-TNF-α agents, as a recent meta-analysis showed only 1 case of tuberculosis (TB) in 1 of 643 patients. 9
