Tuberculosis: Treatment and Prevention
In the pleural thoracentesis is useful to relieve symptoms and to cultivate the bacillus.
The pharmacological treatment of pulmonary tuberculosis can be divided into various schemes depending on the type of Tb. But the primary drugs include the Izonizaida (HAIN), ethambutol, streptomycin, para-aminosalicylic acid (PAS) and Rifampicin.
The secondary drugs are cycloserine, viomycin, pyrazinamide, kanamycin, capreomycin, ethionamide, and thiacetazone and are indicated when the microorganism shows resistance, so that can not be adequately treated with a combination of the primary drugs.PREVENTION
In chemoprophylaxis is not intended to prevent infection, but prevent the development of the disease in subjects who have been infected. And the only drug that has proven effective in such cases is to isoniazid at a dose of 10 mg / kg / day for children and 300 mg/day in adults.
BCG VACCINE .- The BCG vaccine was developed by Calmette and Guérin from a strain of Mycobacterium bovis that was subcultured 231 times, until it lost its power to infect (pathogenicity) man.
BCG vaccination prevents TB infection and limit its spread, why it applies to infants and decreases the frequency of severe forms (miliary and meningeal).
Usually given in the deltoid region, intradermal in all children from birth to 14 years old without previous tuberculin test. The protection provided decreases after 10 years so another application is recommended especially for children living in endemic areas (high risk).
