The treatment of latent tuberculosis infection (LTBI) is essential to controlling and eliminating TB by reducing the risk that TB infection will progress to disease. Latent tuberculosis will convert to active tuberculosis in 10% of cases (or more in cases of immune compromised patients).
A patient is expected to be free from all living TB bacteria after six months of therapy in Pulmonary TB or 8-10 months in Miliary TB. [ citation needed ] Latent tuberculosis or latent tuberculosis infection (LTBI) is treated with three to nine months of isoniazid alone.
Diagnosis of latent TB relies on the tuberculin skin test (TST) or blood tests. [10] Prevention of TB involves screening those at high risk, early detection and treatment of cases, and vaccination with the bacillus Calmette-Guérin (BCG) vaccine. [3] [4] [5] Those at high risk include household, workplace, and social contacts of people with ...
FDG PET/CT can play several useful roles in patients with confirmed or suspected TB. [16] These roles include detection of active TB lesions, assessment of disease activity, differentiation between active and latent disease, assessment of disease extent (staging), monitoring response to treatment, and identification of potential biopsy target. [16]
Treatment of latent TB infection typically involves using a single drug for a prolonged period of time—the most common approach is Isoniazid for 9 months. Treatment of active TB disease is typically a combination of antibiotics, which results in patients being non-infectious to others usually within a few weeks.
Tuberculosis creates cavities visible in x-rays like this one in the patient's right upper lobe.. A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary.
The tuberculosis (TB) blood test, also called an Interferon Gamma Release Assay or IGRA, is a way to diagnose latent TB. A variety of neurological complications have been noted in miliary tuberculosis patients—tuberculous meningitis and cerebral tuberculomas being the most frequent. However, a majority of patients improve following ...
Clinical evaluation and additional tests (such as a chest radiograph, sputum smear, and culture) are needed to differentiate between a diagnosis of latent TB or active TB. Advantages of the test are: Requires a single patient visit to draw a blood sample. Results can be available within 24 hours.
