Pulmonary disease by mycobacterium intracellulare in an immunocompetent patient: Report of a case in Peru

Abstract

We present the case of an immunocompetent patient whose illness began at age 49 with a cough, followed by purulent and hemoptoic sputum; bronchiectasis was diagnosed. Three years later, after hemoptysis, she underwent medial segmentectomy of the middle lobe and was asymptomatic for months. When tuberculosis was found in the pathology report, she was treated with 4HREZ2R2H2. Five years later her BK was 2+, thus receiving a new scheme of 4HREZ2R2H2, which did not succeed in obtaining negative results and the treatment was declared as a failure. After genotyping her Mycobacterium intracellulare culture, the patient received azithromycin, moxifloxacin and ethambutol. There was improvement, but she abandoned the treatment at 8 months; she restarted it 18 months later, along with treatment for depression and gastroesophageal reflux. After one month the patient was asymptomatic, but she had a dermal reaction to moxifloxacin which was replaced with amikacin. One year later, she was cured and discharged, at the age of 64.
