Real-World Status in the Treatment of Latent Tuberculosis Infection in People Living with HIV in Korea.

This retrospective study analyzed medical records of 1,392 people living with HIV (PLWH) diagnosed with latent tuberculosis infection (LTBI) at two provincial central hospitals from 2011 to 2022. LTBI was diagnosed in 152 patients (10.9%) patients aged ≥18 years. Among the 113 patients who initiated treatment, 96 (85.0%) completed isoniazid therapy, while 17 (15.0%) discontinued due to patient refusal, liver function test abnormalities, and other reasons. During a mean follow-up period of 55.0±31.0 months, two cases of active tuberculosis were reported in both the treatment non-completion group (3.6%) and the completion group (2.1%). This study provides recent real-world insights into LTBI treatment among PLWH in Korea.
