Immune Reconstitution Inflammatory Syndrome (IRIS) is rare in immunocompetent individuals. This case shows IRIS can occur in immunocompetent children with central nervous system tuberculosis.
Area of Science:
- Immunology
- Infectious Diseases
- Neurology
Background:
- Immune Reconstitution Inflammatory Syndrome (IRIS) is an exaggerated inflammatory response during immune recovery, typically seen in immunocompromised patients.
- While rare, IRIS can manifest even in immunocompetent individuals, presenting a diagnostic challenge.
Observation:
- A 5-½-year-old immunocompetent female child diagnosed with central nervous system (CNS) tuberculosis without HIV infection.
- The patient developed paradoxical IRIS, characterized by clinical worsening despite anti-tuberculosis treatment.
Findings:
- The patient's condition improved with supportive care and continued anti-tuberculosis therapy.
- This case highlights that tuberculosis-associated IRIS is possible in immunocompetent hosts.
Implications:
- Clinicians should consider IRIS in the differential diagnosis of worsening neurological symptoms in immunocompetent patients with tuberculosis.
- Understanding IRIS in diverse populations is crucial for effective management of infectious diseases and inflammatory responses.

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.

Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis V
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 II
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...
