Pathogenesis Some infected older persons, given enough time, will eventually eliminate the viable AFB and revert to a negative tuberculin reaction status. 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. 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 These older persons have no lasting immunity and are thus susceptible to re infection

Diagnosis: Clinical Manifestations Diagnosis: Clinical Manifestations The presence of acute or chronic illnesses existing concurrently with tuberculosis may obscure the diagnosis by altering the presentation 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 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 Infection Diagnosis: Testing for M. tuberculosis Infection Mantoux tuberculin skin test (TST) Skin test that produces delayed-type hypersensitivity reaction in persons with M. tuberculosis infection Quantiferon Gold Blood test that measures and compares amount of interferon-gamma (IFN- ) released by blood cells in response to antigens
Diagnosis: QuantiFERON ® - Gold Test Diagnosis: QuantiFERON ® - Gold Test Cells that recognize the antigen release interferon- Cells that recognize the antigen release interferon- Amount of interferon released in response to tuberculin is compared to amount released in response to other antigens 5 Amount of interferon released in response to tuberculin is compared to amount released in response to other antigens 5
