TY - JOUR T1 - The second recurrence of <em>Mycobacterium avium</em> complex lung disease after successful treatment for first recurrence JF - European Respiratory Journal JO - Eur Respir J DO - 10.1183/13993003.01038-2018 VL - 53 IS - 1 SP - 1801038 AU - Byoung Soo Kwon AU - Tae Sun Shim AU - Kyung-Wook Jo Y1 - 2019/01/01 UR - http://erj.ersjournals.com/content/53/1/1801038.abstract N2 - The recurrence rate of Mycobacterium avium complex (MAC) lung disease (LD) after successful treatment is approximately 10–48% [1–3]. These episodes represent true relapse from the same MAC strain or a reinfection with a new strain [1, 2, 4]. Nodular bronchiectatic (NB) type, old age, lower body mass index (BMI) and M. avium isolates are related to recurrence [3, 5, 6].Approximately 60% of patients who are successfully treated for their first recurrence of MAC lung disease eventually experience a second recurrence. Approximately half of the second recurrence patients require anti-MAC treatment. http://ow.ly/3G2R30meImC ER -
