Abstract:
Cases of active tuberculosis (TB) in the U.S. Military have fallen over the last century in large part due to improved screening and treatment options. The subset of multidrug-resistant TB (MDR-TB) is almost nonexistent within the U.S. Military. We present a case of MDR-TB in an active duty U.S. Military health care worker and discuss several considerations for treatment that may present challenges for U.S. Military medical practitioners. A 30-year-old active duty Soldier was referred to Army public health services after a bronchoscopy sample was positive for Mycobacterium tuberculosis complex. Sputum smears were negative for acid-fast bacilli, suggesting lower risk for community spread. One month after initiation of the standard 4-drug regimen for active TB, genetic susceptibility testing found the patient's M. tuberculosis isolate to be resistant to rifampin, isoniazid, and pyrazinamide. Contact investigation efforts among co-workers and family members fortunately found no new interferon-gamma release assay conversions. Coordination of public health assets to ensure a successful treatment regimen occurred across varied local, state, and federal agencies. Atypical medications required coordination with the FDA for procurement. An extensive surveillance plan for medication adverse effects was required. Finally, questions of public health authority versus patient autonomy arose requiring multidisciplinary input and ethical discussions.

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
