Definition of TB
Tuberculosis or TB is defined as an infectious disease that is triggered by the bacteria Mycobacterium tuberculosis. TB typically affects the lungs but can also infect several other organs within the body. A person may become infected with the bacteria if he or she inhales miniature particles of sputum that are airborne.
Symptoms of TB
TB infection will typically begin in the upper portion or lobe of the lungs. It is possible for the immune system to impede the proliferation of the bacteria.
Consequently the immune system can cause the lung infection to become inactive. Nevertheless if the immune system is incapable of containing the TB bacteria, the bacteria will multiply becoming active in the lungs and also will be able to travel to other areas in the body.
The symptoms may not occur until months later. The normal symptoms that are evident in an active TB infection may include the following:
• Unexpected weight loss
• Night Sweats
• Coughing which may be associated with sputum and/or blood.
• Shortness of breath
Treatment for TB
In cases where it is discovered that the person has an inactive from of infection, treatment with an antibiotic may be administered to reduce the risk that the person will develop an active infection. The antibiotic that may be utilized is isoniazid (INH). This should be used for twelve months to ensure that the infection is entirely destroyed.
Active TB is typicallytreated with a few kinds of medications including isoniazid. Rifampin (Rifadin), ethambutol (Myambutol), and pyrazinamide along with the major medication isoniazid (INH). Four drugs are generally taken for the first two months of therapy to help destroy any probable resistant strains of bacteria. Once this course is completed the number of medications used is generallydecreased to two drugs for the rest of the treatment. This will depend on drug sensitivity testing that is generally relevant at this point in the course of treatment. Streptomycin, a medication that is injected, can be utilized, specifically when the disease is intenseand/or if the individualcannot or does not wish to take the medications orally. It is probable for treatment to last several months or even as much as years.
Surgery on the lungs may be utilized to aid in curing the disease, nonetheless it is rarely performed.
