TREATMENT
GUIDELINES
TUBERCULOSIS
Dr. Aswini Kumar Mohapatra
Professor and Head
Dept. of Pulmonary Medicine
AIMS OF TREATMENT –
1. To cure the patient of TB
2. To prevent death from active TB
3. To prevent death from relapse of TB
4. To decrease transmission of TB to others
5. To prevent development of acquired drug
resistance
INITIAL / INTENSIVE PHASE (2 months)
CONTINUATION PHASE (4 - 6MONTHS)
NEW CASES
SMEAR POSITIVE SMEAR NEGATIVE
1.Tuberculosis suspect-
 Any person who presents with symptoms or
signs suggestive of TB
2.Definite case of TB-
 Patient with M.TB complex identified from a
clinical specimen, either by culture or by a newer
method such as molecular line probe assay
 One or more initial sputum smear examinations
positive for AFB is also considered to be a
‘definite’ case
3. Case of TB-
 A definite case of TB or one in which a health
worker has diagnosed TB and has decided to treat
the patient with a full course of TB treatment
 Cases of TB also classified according to the-
a. anatomical site of the disease
b. bacteriological results
c. history of previous treatment
d. HIV status of the patient
4. Smear negative PTB cases-
Smear negative PTB cases should either:
A. Sputum smear negative but culture positive for
M. tuberculosis
OR
B. meet the following diagnostic criteria :
 decision by a clinician to treat with a full course
of anti TB therapy; and
 radiographic abnormalities consistent with active
pulmonary TB and either:
-laboratory or strong clinical evidence of HIV
infection
or:
- if HIV negative and no improvement in response
to a course of broad spectrum antibiotics
A. FIRST LINE DRUGS:-
 Isoniazid (H)
 Rifampicin (R)
 Pyrazinamide (Z)
 Streptomycin (S)
 Ethambutol (E)
B. SECOND LINE DRUGS:-
 Para-amino salicylic Acid
 Ethionamide
 Cycloserine
 Kanamycin / Amikacin / Capreomycin
 Macrolides
 Fluroquinolones

Three properties:
1. Bactericidal activity
2. Sterilizing activity
3. Ability to prevent resistance
(bacteriostatic activity)
 INH and Rifampicin-
Most powerful bactericidal drugs
active against all population of TB bacilli
 Rifampicin -
most potent sterilizing drug
 Pyrazinamide -
bactericidal- active only in acidic environment
 Streptomycin -
Bactericidal- against rapidly multiplying bacilli

1. NEW CASE-
A patient who has never had treatment for TB
OR
Who has taken ATT <1 month
2. REPALSE-
A patient previously treated for TB declared
cured / treatment completed
Subsequently diagnosed with bacteriologically positive
(smear or culture) tuberculosis
3. TREATMENT FAILURE-
A patient who while on treatment, remained or
became again smear positive five months or later after
commencing treatment
OR
Initially smear negative before starting treatment and
became smear positive after the second month of
treatment
4. DEFAULTER-
A patient who returns to treatment, positive
bacteriogically, following interruption of
treatment for 2 months or more
5. OTHERS-
All cases that do not fit the above difinitions.
Chronic Case A patient who is sputum
positive at the end of a retreatment regimen
6. TRANSFER IN-
A patient who has been transferred from another
TB register to continue treatment
Recommended treatment regimens are similar
irrespective of site of the disease
A patient with both pulmonary and extra
pulmonary TB
Classified as a case of PTB
