Abstract

We report a case of an adult male with a history of recurrent cough and chest pain for five years. Mycobacterium arosiense was identified in his alveolar lavage fluid, and whole-exome sequencing revealed heterozygosity for CD209 in this patient. After 17 months of combined antibiotic therapy, the patient recovered completely.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
