Pathogenesis

Some infected older persons, given enough time, will eventually eliminate the viable AFB and revert to a negative tuberculin reaction status.

A major component of the immune system affected by aging is a decline in the ability of aging T- lymphocytes to produce specific cytokines.

These older persons have no lasting immunity and are thus susceptible to re infection

Case Report

Retrospective study, 7439 pts under DOTS, Jan 1996 to March 2001 Treatment outcomes of NSP geriatric TB patients vs younger

pts• Lower sputum conversion: 75.3% vs 85.7%• Lower cure rates: 69.2% vs 80.7%• Higher exclusion rates from DOTS: 2.3% vs 0.15%• Higher treatment failure rates

ObjectivesOf Programme 2012-2017

1. Achieve 90% notification rate for all.

2. Achieve 90% success rate for new and 85% for re-treatment.

3. To improve the outcomes of Drug Resistant cases.

4. Achieve decreased morbidity and mortality of HIV and TB.

5. Improve outcomes TB care in private sector.

Control Strategies

Stopping Progression from infection to active disease

Diagnosing & treating active disease

Between young and elderly TB patients No significant difference in• Adverse drug reactions• Favorable Treatment outcomes

Management Strategies

Strategy for early case detection by improving diagnostic facilities

Diagnostic algorithm should go beyond the passive case finding

Communication strategies to bring people to health facilities

Improve the living standards

Development of the wave of tuberculosis epidemic through time

Future -Strategies

New tools : Point of care test New policies : Use of Technology New Delivery models : Public

Private/Private mix Resources : High allocation Innovative amendment in RNTCP

Diagnosis: Clinical Manifestations

The presence of acute or chronic illnesses existing concurrently with tuberculosis may obscure the diagnosis by altering the presentation

Tuberculosis in an elderly person with chronic obstructive pulmonary disease (COPD) or lung cancer may be misdiagnosed, delaying therapy or may be completely missed, only to be found at autopsy

Diagnosis: Testing for M. tuberculosis InfectionMantoux tuberculin skin test (TST)Skin test that produces delayed-type hypersensitivity reaction in persons with M. tuberculosis infection Quantiferon GoldBlood test that measures and compares amount of interferon-gamma (IFN-) released by blood cells in response to antigens

Diagnosis: QuantiFERON®-Gold Test

• Cells that recognize the antigen release interferon-

• Amount of interferon released in response to tuberculin is compared to amount released in response to other antigens5
