Purpose of review Tuberculosis (TB) is a millenarian chronic infection and, yet, remains a major global health problem. The interaction between systemic lupus erythematosus (SLE) and TB is complex, as one seems to be a risk factor for the development of the other. SLE patients are more likely to develop TB, that is more frequently extrapulmonary, with more extensive pulmonary involvement, and with a higher relapse rate. Recent findings Different studies suggest that TB is more prevalent in SLE patients and that TB may actually be a risk factor for the development of the disease. Molecular and epidemiological data suggest that TB may be involved in the pathogenesis of SLE. Summary We reviewed the most relevant aspects of TB infection in SLE patients, including the burden of TB, its role in inducing flare and its perpetuation, risk evaluation and prevention, and pearls and pitfalls when assessing extrapulmonary TB in SLE patients. We conclude that a high suspicion of TB in SLE patients from endemic countries should be kept in mind, especially in those with nephritis and high cumulative doses of corticosteroids.
