Quiescent Tuberculosis
Overview of Quiescent Tuberculosis
Quiescent Tuberculosis, also known as Latent Tuberculosis Infection (LTBI), is a form of tuberculosis where a person is infected with the tuberculosis bacteria but does not show any symptoms and cannot spread the disease to others. It differs from active TB, which causes illness and is contagious. Although people with quiescent or latent TB appear healthy, the bacteria remain in their bodies in an inactive state and can become active later in life, especially if the immune system weakens. Detecting and treating latent TB is crucial to prevent future outbreaks of active TB disease.
Types of Quiescent Tuberculosis
- Latent Tuberculosis: The TB bacteria are present but inactive. No symptoms, not contagious.
- Active Tuberculosis: The bacteria are multiplying, causing illness. This form is contagious.
- Pulmonary TB: Affects the lungs and is the most common and infectious type.
- Extrapulmonary TB: Affects other body parts like lymph nodes, bones, kidneys, or brain.
- Miliary TB: A rare, severe form where bacteria spread throughout the body by the bloodstream.
- Drug-resistant TB: Caused by bacteria resistant to standard TB medications.
Symptoms of Quiescent Tuberculosis
- No cough, fever or chest pain
- No weight loss or fatigue
- Normal chest X-ray and physical exam
- Positive TB skin test or blood test only
- Can live without symptoms for years unless activated
Causes of Quiescent Tuberculosis
- Infection by Mycobacterium tuberculosis bacteria
- Inhalation of droplets from a person with active TB
- Close contact with someone having contagious pulmonary TB
- Weakened immune system allowing dormant bacteria to activate
- Living in crowded or poorly ventilated areas
- History of untreated or incomplete TB treatment
Complications in Quiescent Tuberculosis
- Can turn into active TB if not treated
- Increased risk in people with weak immune systems (HIV, cancer, diabetes)
- May affect lungs, bones, kidneys, brain or lymph nodes if reactivated
- Potential public health risk if it becomes active and spreads
- Missed diagnosis can delay early prevention
Risk Factors of Quiescent Tuberculosis
- Living with someone who has active TB
- Weakened immune system or chronic illness
- HIV infection or organ transplant
- Long-term use of immunosuppressive drugs
- Malnutrition or poor general health
- Healthcare workers in TB-endemic areas
- People from countries with high TB prevalence
- Homelessness, incarceration or substance abuse history
Preventions of Quiescent Tuberculosis
- Regular TB screening for high-risk individuals
- Prompt treatment of latent TB to prevent activation
- Ensuring good ventilation in living and working spaces
- Using protective masks in TB-prone settings
- BCG vaccination in countries with high TB rates
- Avoiding close contact with active TB patients
- Strengthening immune health through proper nutrition
- Education on TB symptoms and transmission
Diagnosis of Quiescent Tuberculosis
- Tuberculin Skin Test (TST): A small injection under the skin to check for immune response.
- Interferon-Gamma Release Assays (IGRAs): A blood test for detecting TB infection.
- Chest X-ray: Helps rule out active TB disease.
- Medical history evaluation and physical examination to assess risk factors and symptoms.
- Further tests may be advised if activation is suspected.
Treatments of Quiescent Tuberculosis
- Antibiotic therapy: Medications such as isoniazid or rifapentine regimens to kill dormant TB bacteria.
- Treatment duration: Usually lasts from 3 to 9 months depending on the drug combination.
- Complete course: Important to finish the full treatment even without symptoms.
- Regular monitoring: Required during treatment to check for side effects.
- High success rate: Prevents the development of active TB in most cases.
Prognosis of Quiescent Tuberculosis
- Most individuals remain symptom-free throughout life if untreated.
- With proper treatment, the risk of developing active TB is greatly reduced.
- Those who complete treatment rarely develop TB in the future.
- Better outcomes are observed in individuals without other medical conditions.
- Early intervention provides long-term health and protection.
