Drugs and Medicines to be Used in Tuberculosis

There are approximately 8.8 million cases of tuberculosis worldwide, added than 40% of these cases are in South East Asia; India has 53.3% of South East Asian burden. Globally, one man is infected with tubercle bacilli every second. Till about the first half of the century, the diagnostic verdict of tuberculosis was considered a death knell. It meant psychological depression, social isolation, and economic hardships for the family. The only treatment available was rest and a protein comfortable diet, and when possible, the patient was sent to a sanatorium for a exchange of environment. He would go to any comer of the state to consult the most all around physicians, the crudest quacks, or priests with assumed healing powers, and was receptive to any available advice. Today, the prospects of a tuberculosis patient have changed entirely. It is no longer considered a dreaded disease but one which can be effectively controlled and cured by drugs.
Tuberculosis, a tissue-destroying (necrotizing) infection, is caused by inhalation of the tubercle bacilli (mycobacterium tuberculosis). The lungs are most commonly affected, on the contrary it may spread to the kidneys, bowels, bones, lymph nodes, meninges, or any other thing of the body. This infection may cause clinical disease either 1) shortly after inoculation*, sometimes called 'primary' tuberculosis; or 2) after months or decades of dormancy, which is erroneously referred to as 'reinfection' tuberculosis. Active tuberculosis is potentially fatal and may be transmitted to susceptible individuals. About one-third of the cases are discovered when the patient comes with a low grade fever; another one-third with unrelated complaints; and the remaining are those undergoing routine medical examination. In some cases of HIV infected persons, tuberculosis occurs in the rapidly progressive form.
Diagnosis
A tuberculosis patient may not be aware about his illness as the symptoms approximative fever, blackness sweating, cough, and headache appear slowly and are gentle in nature. In the severe form, there may be breathlessness and palpitation on exertion, blood in the sputum (hemoptysis), bitterness in the chest or abdomen and weight loss. The diagnosis is made by a positive tuberculin skin test (Mantoux test), sputum subject for tubercle bacilli (acid quickly bacilli), high ESR (blood test), and Radioactivity of the lungs which shows opacities or cavities (shadows) at the apex or elsewhere.
Treatment
The treatment of tuberculosis consists of preventive therapy and curative therapy.
Preventive Therapy
Preventive therapy of tuberculosis has two large-scale goals: 1) to prevent infection in an idiosyncratic with a negative tuberculin test nevertheless who has had intimate contact with an active case; 2) to an prevent active disease in an individual who is infected however does not have any symptoms (significant reaction to tuberculin test, but chest X-ray is negative).
In children who come in contact with tuberculosis patients, tuberculin testing is essential. If the inspection is negative, BCG vaccination should be given. However, If the elimination is positive, a chest X-ray is essential. If this is abnormal, a diagnosis of primary tuberculosis is feasible and conventional anti-tuberculosis treatment should be given. Provided the chest Radiograph is normal, then chemoprophylaxis with isoniazid 5 to 10 mg/kg daily for 6 to 12 months is recommended.
Patients receiving corticosteroids or immuno-suppressive treatment, or who develop diabetes or malignancy should be examined for an old 'inactive' tuberculosis lesion wound up an Actinism and sputum inquiry as it may become active in them. It may be wise to come across a trail of anti-tubercular drugs to make the patient 'safe' and avoid the disease from developing.
Note: BCG vaccination has been used for various decades for conferring immunity against tuberculosis bacilli. However, controversy exists regarding its efficacy. In India, it has been shown to provide protection against tuberculosis alone in about 30% patients.
