Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis.
The bacteria usually attack the lungs, but they can also damage other parts of the body.
TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks.
One is more likely to get TB if the person has a weak immune system.
PTB Category IV MDR-TB
![Page 40: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/40.jpg)
Symptoms of TB in the lungs include:
Cough for two or more weeks, with or without:
FeverChest and/or back pains not referable to any
MS disorderHemoptysis or recurrent blood-streaked
sputumSignificant weight lossOther symptoms, such as sweating, fatigue,
body malaise, shortness of breath
![Page 41: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/41.jpg)
If not treated properly, TB can be deadly.
One can usually cure active TB by taking several medicines for a long period of time.
People with latent TB can take medicine so that they do not develop active TB.
![Page 42: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/42.jpg)
What is DOTS?
Tuberculosis is completely curable through short-course chemotherapy.
Treating TB cases who are sputum-smear positive (and who can therefore spread the disease to others) at the source, it is the most effective means of eliminating TB from a population.
![Page 43: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/43.jpg)
What is DOTS?
DOTS or Directly Observed Treatment Short course is the internationally recommended strategy for TB control that has been recognized as a highly efficient and cost-effective strategy.
DOTS comprises five components:
![Page 44: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/44.jpg)
5 Components of DOTS
1. Sustained political and financial committment.
TB can be cured and the epidemic reversed if adequate resources and administrative support for TB control are provided.
![Page 45: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/45.jpg)
5 Components of DOTS
2. Diagnosis by quality ensured sputum-smear microscopy.
Chest symptomatics examined this way helps to reliably find infectious patients.
![Page 46: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/46.jpg)
5 Components of DOTS
3. Standardized short-course anti-TB treatment (SCC) given under direct and supportive observation (DOT).
Helps to ensure the
right drugs are taken at the right time for the full duration of treatment.
![Page 47: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/47.jpg)
5 Components of DOTS
4. A regular, uninterrupted supply of high quality anti-TB drugs.
Ensures that a credible national TB program does not have to turn anyone away.
![Page 48: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/48.jpg)
5 Components of DOTS
5. Standardized recording and reporting
Helps to keep track of each individual patient and to monitor overall program performance.
![Page 49: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/49.jpg)
The new global Stop TB Strategy builds on the DOTS strategy, which remains the fundamental basis for TB control.
The six additional essential elements in the new strategy are:
![Page 50: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/50.jpg)
The six additional essential elements in the new strategy are:
1. Sustaining, improving and accelerating quality DOTS expansion
2. Addressing TB-HIV, MDR-TB and other special challenges
TB/HIV collaborative interventions DOTS-Plus for MDR-TB Reaching vulnerable, high risk groups
![Page 51: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/51.jpg)
The six additional essential elements in the new strategy are:
3. Contributing to health system strengthening
TB control innovations that strengthen health systems Adaptation of innovations from other TB control
programs Practical Approach to Lung Health
4. Engaging all care providers
Public-private partnerships Ensuring equitable access to international standards of
care for TB to all
![Page 52: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/52.jpg)
The six additional essential elements in the new strategy are:
5. Empowering patients and communities
Advocacy, communication and social mobilization Community-based TB care
6. Enabling and promoting research
Program-based operational research Development of new diagnostics, drugs and vaccines

Global Situation of MDR-TB
MDR-TB is present in five continents, a third of the countries surveyed having levels above 2% among new patients.
In Latvia 30% of all patients for treatment had MDR-TB.
Russia when surveyed had 5% with MDR-TB. In the Dominican Republic, 10% had MDR-TB. In Africa, Ivory Coast had also emergence of
MDR-TB.Preliminary reports from Asia (India and China)
show high levels of drug resistance as well. In the State of Delhi, India, 13% of all TB patients had MDR-TB.

Philippine Setting
Data from Makati Medical Center DOTS Clinic (2003) indicates high incidence of MDR TB.
Approximately 30% of isolates tested were resistant to all five first line drugs, 39.4% to four, 16.8% to three, 12.1% to two.
Fluoroquinolone resistance was noted in 40.9% isolates.
![Page 68: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/68.jpg)
Epidemiology
MDR-TB afflicts countries with poor health infrastructure
Also likely to break out in industrialized countries
During the late 1980s and early 1990s outbreaks of MDR-TB in North America and Europe killed over 80% of those who contracted it.
The major TB outbreak in New York in the early 1990s was primarily a MDR-TB epidemic, with one in ten cases being drug-resistant.

Key factors for the management of MDR TB:
Diagnosis of MDR TB Reliable susceptibility testing Prevention of MDR TB In new cases In old cases Designing an appropriate regimen Essential Drugs Second line Drugs Cross resistance Ranking with respect to Efficacy, Cost, Tolerance Reliable drug supply of second line drugs
![Page 70: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/70.jpg)
Principles to be followed while treating MDR-TB patients:
Starting MDR-TB drug regimen Check the history of the patient carefully for previous treatment regimens. Check whether all drugs in the previous regimens have been taken and for
how long. Determine the status of sputum smears at all junctures (in terms of
positivity ,conversions and sensitivities – if available).
Confirmed/ Strongly suspect MDR TB
Counsel the Patient and family members
Send Tissue / sputum for culture and sensitivity testing (if available)
Start MDR Regimen
![Page 71: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/71.jpg)
Treatment Plan:
Use at least 4 – 5 drugs as long as these include 2 drugs not previously taken.
Do not add a single drug to a failing regimen to avoid resistance to the new drug.
Consider continuing with isoniazid and rifampicin (most bactericidal) despite resistance.
Either pyrazinamide or ethambutol may be discontinued.

Treatment Plan:
Continue treatment for 18 months more from the time the patient’s sputum becomes AFB and culture negative.
Get cultures to check sensitivity of TB organism.
![Page 73: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/73.jpg)
Treatment Plan:
Consider surgery for unilateral cavitary lesions in whom MDR-TB is established in the laboratory.

Prevention
1. Vaccination
Attenuated strain of M. bovis, bacille Calmette-Guerin (BCG)
Protects infants and young children below 5 years of age
Efficacy unclear in other situations
![Page 75: Case 2 Tbdots-mdr](https://reader033.vdocument.in/reader033/viewer/2022061123/547563f6b4af9f276c8b4715/html5/thumbnails/75.jpg)
Prevention
2. Treatment of latent infection
Candidates for chemoprophylaxis are identified by TST (Tuberculin Skin Testing)
(+) – determined by reaction size and risk group
If (+), consider drug treatment
