Abstract:
Tuberculosis (TB) and leprosy are major mycobacterial infections in Indonesia, but coinfection is rare. We describe a 57-year-old male with pulmonary TB and borderline lepromatous leprosy complicated by reversal reaction. He also had type 2 diabetes mellitus and oral candidiasis. TB was confirmed by GeneXpert MTB/RIF, rifampicin-sensitive sputum culture, and chest radiography, showing right suprahilar infiltrates. Leprosy was diagnosed by slit skin smear positive for Mycobacterium leprae. During the 6th month of multidrug therapy (MDT), he developed reversal reaction with fever, painful erythematous plaques, and sensory loss. Management included systemic corticosteroids, continuation of MDT without rifampicin, anti-TB drugs, and supportive care. Clinical improvement was observed after treatment modification. This case highlights the complex immunological interplay between M. leprae and Mycobacterium tuberculosis, therapeutic challenges of drug interactions, and the importance of multidisciplinary management.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

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.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
