Abstract
Mycobacterium tuberculosis (MTB) can disseminate to extrapulmonary organs, particularly in severely immunosuppressed patients. Confirmation of active MTB infection is often difficult in subjects with a contraindication for invasive procedures. A case of disseminated MTB infection after hematopoietic stem cell transplantation is reported herein. Circulating cell-free DNA from the patient showed positive amplification of an MTB complex-specific sequence using a digital PCR technique. The MTB infection was confirmed by positive acid-fast staining and an approved quantitative PCR assay using liver tissue obtained at autopsy. The detection of MTB in circulating cell-free DNA using this technique may represent a less invasive diagnostic tool for pulmonary and extrapulmonary MTB infections.
