Fig. 1From: Chest roentgenography is complementary to interferon-gamma release assay in latent tuberculosis infection screening of rheumatic patientsThe chemoprophylaxis after LTBI screening. Forty-six patients had positive IGRA results. Forty patients received isoniazid LTBI treatment. Thirty-one (77.5%) completed LTBI therapy and one of them had late hepatitis at the end of nine-month isoniazid therapy. Five patients prematurely stopped chemoprophylaxis due to adverse drug effects. Two patients decided to stop biologics and isoniazid prophylaxis. One stopped biologics and LTBI treatment due to NTM in sputum. Another one received chest specialist follow-up instead of chemoprophylaxis.
