Definition!
TB is spread from person to person through the air when someone with active TB disease coughs or sneezes. The disease is more common in areas with poor sanitation, crowded living conditions, and limited access to healthcare.
Symptoms!
1.
Persistent cough: A cough that lasts
for more than two weeks is one of the most common symptoms of TB.
2.
Chest pain: Chest pain may be
present and can worsen while coughing or breathing.
3.
Coughing up blood: Coughing up blood
or sputum with blood is also a symptom of TB.
4.
Fever: A low-grade fever
that lasts for several weeks is a common symptom of TB.
5.
Night sweats: Night sweats that
soak your clothes and sheets, even when the room is cool, are a common symptom
of TB.
6.
Weight loss: Unexplained
weight loss or loss of appetite is another common symptom of TB.
7.
Fatigue: Feeling weak or
tired all the time is another symptom of TB.
8.
Other symptoms: In some cases, TB
can cause symptoms such as joint pain, abdominal pain, or a rash.
It's important to note that not everyone who is infected with TB will have symptoms. People with latent TB infection may not have any symptoms at all but can still develop active TB disease later if they do not receive treatment. If you suspect you may have TB, you should see a healthcare provider for an evaluation and diagnosis.
Diagnostic Tools for Tuberculosis!
Here are some common diagnostic tools for
TB:
1.
Tuberculin skin test (TST): This test involves
injecting a small amount of purified protein derivative (PPD) into the skin on
the forearm. The healthcare provider will then check the site for a reaction
after 48 to 72 hours. A positive result indicates that the person has been
infected with TB bacteria, but it does not indicate whether the infection is
latent or active.
2.
Interferon-gamma release assays
(IGRAs):
These blood tests can detect the presence of TB bacteria in the body by
measuring the release of interferon-gamma in response to TB antigens. IGRAs are
more specific than TST and are less likely to be affected by previous BCG
vaccination.
3.
Chest X-ray: This imaging test
can show abnormalities in the lungs, such as areas of inflammation, cavities,
or nodules. A chest X-ray alone is not enough to diagnose TB, but it can help
confirm the diagnosis in combination with other diagnostic tests.
4.
Sputum Culture: This test
involves collecting a sample of sputum (phlegm) and growing it in a laboratory
to see if TB bacteria are present. This test can take several weeks to produce
results, but it is the most accurate way to diagnose TB.
5.
Molecular tests: These tests, such
as the GeneXpert MTB/RIF assay, can detect TB bacteria in sputum samples within
a few hours using a rapid, automated molecular test. These tests can provide
results quickly and accurately, but they may not be available in all settings.
It's important to seek medical attention
if you suspect you may have TB, and to follow the healthcare provider's
instructions for diagnostic testing and treatment.
Types of Tuberculosis!
1.
Latent TB infection: In this type, a
person is infected with TB bacteria, but the bacteria are not causing any
symptoms. The person is not contagious and does not feel sick. However, the
bacteria can become active later if the person's immune system becomes
weakened. People with latent TB infection may be treated with antibiotics to
prevent the bacteria from becoming active.
2.
Active TB disease: In this type, the
TB bacteria are actively multiplying and causing symptoms. Active TB disease
can affect the lungs (pulmonary TB), but it can also affect other parts of the
body (extrapulmonary TB), such as the brain, kidneys, or spine. Active TB
disease is contagious and can be spread from person to person through the air
when someone with active TB disease coughs or sneezes.
1.
Drug-susceptible TB: This is the most
common form of TB, and it can be treated with a combination of antibiotics.
2.
Multidrug-resistant TB (MDR-TB): This form of TB
is resistant to at least two of the most powerful antibiotics used to treat TB.
MDR-TB is more difficult to treat than drug-susceptible TB and requires longer
treatment with different antibiotics.
3.
Extensively drug-resistant TB
(XDR-TB):
This is a rare and more severe form of TB that is resistant to several
antibiotics. XDR-TB is more difficult to treat and requires specialized care.
It's important to get a proper diagnosis and treatment for TB, as the disease can be serious and potentially life-threatening if left untreated.
Treatment Options!
Here are some common treatment options for TB:
1.
First-line drugs: The most common
drugs used to treat TB are Isoniazid, Rifampin, Ethambutol,
and Pyrazinamide. These drugs are usually taken together for six to nine
months, depending on the type and severity of TB.
2.
Second-line drugs: If a person has
multidrug-resistant TB (MDR-TB) or extensively drug-resistant TB (XDR-TB), they
may require treatment with second-line drugs. These drugs are less effective
than first-line drugs and may have more side effects. Treatment for MDR-TB and
XDR-TB can take up to two years or longer.
3.
Directly observed therapy (DOT): This is a
treatment approach where a healthcare provider or trained healthcare worker
watches the person take their medication to ensure they are taking it correctly
and consistently. DOT can help improve treatment outcomes and reduce the risk
of drug-resistant TB.
4.
Supportive care: In addition to
medication, people with TB may require supportive care to manage their symptoms
and improve their overall health. This may include adequate nutrition, rest,
and treatment for any other health conditions they may have.
It's important to follow the recommended treatment regimen and attend all scheduled appointments with your healthcare provider to ensure the best possible outcome.
