A Brief Introduction of TB- Consumption
  • Consumption- the name for Tuberculosis 100-200
    years ago.
  • Death Certificate- William Guentzel, 1888 at age
    37 in Oak Creek, Wisconsin
  • When I saw this death certificate in about 1977,
    I thought he died of alcoholism- he consumed
    alcohol to death.
  • When we hear of consumption problems today in
    2009, we think of obesity.
  • 100-200 years ago, when they heard of consumption
    problems, it was someone who had wasting disease-
    their body was being consumed by tuberculosis.

5
Basic Definition of TB
  • Tuberculosis- Disease caused by the organism
    Mycobacterium tuberculi
  • Mycobacterium Genus of bacteria
  • M. Tb- spread by pulmonary droplets
  • Dissemination- after entry into the lungs, can
    then disseminate and affect multiple different
    body systems

6
Common Sites of TB Disease
  • Lungs
  • Pleura
  • Central Nervous System
  • Lymphatic System
  • Genitourinary System
  • Bones and joints
  • Disseminated (miliary TB)

    Nodularity and increased reticular pattern in
    the remainder of the Right Lung suggesting
    Co-existent Bronchopneumonia
  • No CT done.

34
Latent TB Infection (LTBI)
  • LTBI is the presence of M. tuberculosis
    organisms (tubercle bacilli) without symptoms or
    radiographic evidence of TB disease.

35
Terminology
  • Treatment of latent TB infection replaces the
    terms preventive therapy and chemoprophylaxis
    to promote greater understanding of the concept
    for both patients and providers.
  • Targeted tuberculin testing is used to focus
    program activities and provider practices on
    groups at the highest risk for TB.

36
LTBI vs. Pulmonary TB Disease
  • Latent TB Infection
  • TST or QFT positive
  • Negative chest radiograph
  • No symptoms or physical findings suggestive of TB
    disease
  • Pulmonary TB Disease
  • TST or QFT usually positive
  • Chest radiograph may be abnormal
  • Symptoms may include one or more of the
    following fever, cough, night sweats, weight
    loss, fatigue, hemoptysis, decreased appetite
  • Respiratory specimens may be smear or culture
    positive

tuberculin skin test QFT (QuantiFERON-TB and
QuantiFERON-Gold) is a blood test to detect M.
tuberculosis infection.
37
Factors That May Cause False-Positive TST
Reactions
  • Nontuberculous mycobacteria
  • Reactions caused by nontuberculous mycobacteria
    are usually ? 10 mm of induration
  • BCG vaccination
  • Reactivity in BCG vaccine recipients generally
    wanes over time positive TST result is likely
    due to TB infection if risk factors are present

101
Case CN MH 392957 SL 17633359
  • CN was a 58 year old Hispanic man who presented
    to MHC ER on 1/20/04 with phlegm production,

103
Case CN Key Points
  • Pts. can have active TB even with a negative PPD.
  • Immunocompromised patients (here with Diabetes)
    are more likely to get TB
  • TB is more common in immigrants, because they
    come from areas with endemic TB
  • TB can present in a miliary (disseminated)
    picture and also with large cavities.

104
Case DW MH 318507
  • DW is a 60 year old man who presented to the SCHC

    months and died of metastatic esophageal cancer.

107
Case DW Key Take Home Points
  • TB can present in places other than the lungs, in
    this case it was the larynx.
  • TB is more prevalent in medically non-compliant
    and compromised people- he not only had
    uncontrolled diabetes and alcoholism, but also an
    occult esophageal cancer.

120
Case J Key Points
  • Patient had previous treatment for active
    tuberculosis Watch such patients closely (if
    they are compliant), and look for recurrence.
  • Immigrants have a higher incidence of TB.

121
Case SS MH 053499
  • S. S. is a 19 year old immigrant from SE Asia who
    presented to the ER at MHC in 2001 after coughing
    up blood for 2 to 3 weeks in increasing amounts.

123
Case SS Treatment
  • Repeat CT scan was done after 6 months with total
    disappearance of the mass.
  • Patient is alive and well in Siouxland.

124
Case SS Key Points
  • Thousands of cases of Sputum and biopsy (-) TB
    are treated every year in the world.
  • Immigrants are at higher risk for TB, even many
    years after arrival.
  • Patient may also have been infected with atypical
    mycobacterium.

125
LG 2/22/2008
  • Patient was a 23 year old Ethiopian Oromo male
    who presented to the MHC ER in Sioux City stating
    that he had a swelling on his neck for awhile.
    Interpreter serves were poor, but he denied pain.
    He recalled no injury or scratch. He denied any
    fevers, lightheadedness, or syncope.

126
LG- Treatment
  • Patient started on 4 drug TB therapy on 2/29/08
    by Dr. Swanson. On 3/26, culture of lymph node
    aspirate identified as M.TB, so this patient did
    have Tuberculosis.

127
LG- Labs
  • Patient started on 4 drug TB therapy on 2/29/08.
    Completed 2 months of 4-drug therapy (Directly
    observed therapy) and 4 more months of 2 drug
    therapy (2 times weekly, DOT). He also did
    Vitamin B6 for 6 months.

128
TB of the Lymph Nodes
  • Patients with lymphatic TB usually present with
    signs and symptoms related to their site of
    disease, although, as with TB anywhere, symptoms
    may be nonspecific (constitutional) or they may
    be absent.
  • Hilar and mediastinal lymphadenopathy are common
    features of primary TB infection, but they also
    may be present in reactivation TB.
  • Enlarged intrathoracic lymph nodes may compress
    airways, creating focal wheezing or bronchial
    obstruction.
  • Source John Bernardo Chapter 19, Tuberculosis,
    in Patricia Walker and Elizabeth D. Barnett,
    eds., Immigrant Medicine, Philadelphia Elsevier
    Saunders, 2007 p. 262.

129
TB of the Lymph Nodes
  • Infected lymph nodes may enlarge further during
    treatment, in a phenomenon often attributed to a
    reconstitution of the cellular immune response,
    as with TB/AIDS patients who are undergoing
    treatment for both diseases.
  • Cervical lymph nodes are commonly the primary
    site of disease.
  • Aspiration of infected material or biopsy are
    often required to differentiate TB lymphadenitis
    from other causes of lymph node enlargement in
    the neck.
  • As with TB adenitis anywhere, treatment with
    multiple drugs is effective, but enlargement of
    involved lymph nodes during treatment, especially
    early, is common.
  • Source John Bernardo Chapter 19, Tuberculosis,
    in Patricia Walker and Elizabeth D. Barnett,
    eds., Immigrant Medicine, Philadelphia Elsevier
    Saunders, 2007 p. 262.

130
Take Home Points- Case LG
  • 1. TB is common amongst immigrants.
  • 2. gt20 of TB cases in immigrants present as
    extrapulmonary TB.
  • 3. In immigrants and Africans, the TB and HIV
    epidemics are linked, so patients with TB need an
    HIV test.
  • 4. Cervical TB, scrofula, is still seen in the
    US, especially amongst immigrants.

131
Case JM
  • HPI Patient was a 33 year old Hispanic male who
    was admitted to MHC on 10/17/01 by Dr. Swanson.
    He had been diagnosed with HIV in June (06/01) at
    a nearby Family Practice office. He had had a
    long history of bouts of low blood pressure,
    dizziness, blurry vision, fatigue. He also had
    oral candidiasis on that day he was seen there.
  • He was subsequently seen on SCHC for entry labs
    on 9/17/01 and he was found to have a CD4 count
    of 50, HIV RNA Viral Load of 241,230.
  • He then came to SCHC for a new patient visit on
    9/27. He was found to have an elevated temp up
    to 101.9 and some slightly enlarged lymph nodes.
    Rapid Strep was negative.

132
Case JM
  • After admission on 10/17, fevers remained high.
    On 10/22, acid-fast sputums came back positive,
    so patient was started on INH, Ethambutol,
    Pyrazinamide, and Rifabutin on 10/22 to treat
    presumed tuberculosis.
  • On 10/20, a surgeon was consulted to biopsy
    cervical lymph node Surgeon declined noting
    Patient has evidence of fevers. Doubt that he
    has any significant malignant adenopathy at this
    time. Would recommend that he be treated for an
    infectious source for his symptoms and if he has
    persistent adenopathy, despite other measures,
    over the next week or two, could reconsider
    biopsy at that time.
  • Correct answer Presumably A Mycobacteria TB, but
    cannot rule out D Mycobacteria Avium

133
Case JM
  • After starting on TB meds (10/22), pt defervesced
    (starting 10/25). He received Epogen and
    Neupogen and by 11/9, his WBC was up to 3370 and
    his H/H 9.9. By 11/9 patient he had 3 negative
    acid-fast sputums and was sent home on 4 drug TB
    treatment INH, PZA, ETH, and Rifabutin. During
    that time, he continued on Combivir and Kaletra.
  • Over the next 2 months, Mycobacterial cultures
    came back positive for Mycobacterium Avium.
  • So real correct answer D) Mycobacterium Avium

Mycobacteria Avium (MAC)
  • Results from disseminated infection with
    Mycobacterium avium-intracellulare.
  • Although prior to the AIDS epidemic, disseminated
    MAC infection had been reported only rarely, this
    infection became one of the most important
    opportunistic infections associated with AIDS in
    many parts of the world.
  • Disseminated MAC occurs almost exclusively in
    AIDS patients with an absolute CD4 count lt50
    however localized MAC infection can occur at
    higher CD4 counts, especially among patients with
    advanced AIDS who have been immune reconstituted
    by ART.
  • In 1992 (before multidrug ART), in the West
    disseminated MAC had an incidence among Americans
    with AIDS of 10 per 100 patient-years by 1998,
    that incidence had declined to 2 per 100
    patient-years as a result of ART.
  • Disseminated MAC has been less common in parts of
    the world where tuberculosis is more prevalent.

Mycobacteria Avium- Clinical manifestations
  • Symptoms are nonspecific and include fever,
    drenching sweats, wasting, and fatigue.
  • Enlargement of the liver, spleen, and abdominal
    lymph nodes are also seen.
  • Anemia, neutropenia, and thrombocytopenia occur
    with bone marrow involvement, and diarrhea,
    malabsorption, and abdominal pain indicate GI
    infection.
  • There have also been reports of localized
    disease, including diarrhea/malabsorption,
    cervical lymphadenitis, pneumonitis,
    pericarditis, osteomyelitis, skin or soft tissue
    abscesses and genital ulcers.
  • Rapid CD4 rebounds due to ART have produced
    Immune reconstitution Associated MAC

136
Mycobacteria Avium-Radiology
  • Involvement of pulmonary parenchyma results in
    diffuse, heterogenous interstitial patterns with
    or without lymphadenopathy.
  • No definite patterns distinguish this or other
    species of mycobacteria from TB on chest films.
  • Also, acid fast sputum stains do not distinguish
    M. avium from M. Tb. A culture is needed to
    delineate the species of Mycobacteria.

137
Mycobacteria Avium-Treatment
  • Induction Macrolide such as clarithromycin 500
    mg BID or azithromycin 500-600 mg PO QD combined
    with either ethambutol 15 mg/kg po QD, or
    rifabutin 300 mg po QD, or perhaps both agents
    for 1 year with discontinuation after immune
    restoration to CD4 count greater than 100.
  • Prophylaxis Azithromycin 1200 mg po Q week or
    Clarithromycin for all HIV patients with CD4
    count less than 50.
