Study Notes
Tuberculosis (TB) Quiz #2 Study Notes
-
Microorganism: Mycobacterium tuberculosis is the causative agent of tuberculosis. It's an acid-fast bacillus with a waxy outer capsule.
-
Latent TB: A person with latent TB has been exposed to the bacteria but is not currently infectious or showing symptoms. The bacteria are present but inactive.
-
Active TB: This is an infectious form of TB where the bacteria are actively replicating and can spread to others. Symptoms include a productive cough with blood-tinged sputum, fatigue, weight loss, night sweats, and fever.
-
TB Transmission: TB is spread through airborne droplets produced when an infected person coughs, sneezes, speaks, or sings. It's crucial to note that TB is not spread through casual contact like touching a person's skin.
-
Risk Factors for Active TB: Immunocompromised individuals, such as those undergoing chemotherapy, are at higher risk of developing active TB. Also, individuals with poor living conditions and inadequate healthcare access have a higher prevalence of TB.
-
Diagnosis of TB: A positive Mantoux (PPD) test, sputum culture (gold standard) and chest X-ray help confirm a diagnosis. A positive PPD means further testing is needed, a chest X-ray is often next.
-
Treatment & Management: TB treatment requires a multi-drug regimen and must be completed fully. Early diagnosis and treatment are crucial to prevent transmission and development of drug-resistant TB. Failure to complete the treatment can lead to the development of drug-resistant forms of TB.
-
Treatment Side Effects: Some TB medications have side effects like optic neuritis (rifampin & ethambutol).
-
Treatment Adherence: Directly Observed Therapy (DOT) is a strategy used to improve treatment adherence by having a healthcare worker observe the patient taking their medication.
-
Preventing TB Spread: To prevent the spread of TB, patients should be placed in airborne isolation in a negative-pressure room. All those around the patient should be wearing N95 masks as a precaution.
-
Non-infectious Criteria: A patient is considered non-infectious when they have had three consecutive negative AFB sputum smears, experience clinical improvement, and have been undergoing treatment for at least two weeks.
-
Prophylactic Treatment: HIV-positive individuals with latent TB and healthcare workers exposed to active TB should receive prophylactic treatment to prevent the progression to active TB.
Clinical Manifestations
- Characteristic Symptoms: A productive cough with blood-tinged sputum (hemoptysis) is a key symptom of active TB. Other symptoms include night sweats, weight loss, and fatigue.
Diagnostic Testing
- Gold Standard: The gold standard for confirming active tuberculosis is sputum culture.
Complications
- Major Complications: One major complication of untreated or poorly managed TB is pulmonary fibrosis, which is permanent lung scarring. Miliary TB occurs when the bacteria have spread beyond the lungs through bloodstream dissemination. A complication of active TB that may present with severe clinical symptoms is a significant amount of blood loss in secretions, which can be life threatening. Poor management of TB can have long term negative consequences on health.
