4A 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.
5Basic 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
6Common 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.
34Latent TB Infection (LTBI)
- LTBI is the presence of M. tuberculosis
organisms (tubercle bacilli) without symptoms or
radiographic evidence of TB disease.
35Terminology
- 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.
36LTBI 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.
37Factors 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

97Case AD Treatment
- Pt received INH for 3 weeks (7-18-01 to 8-8-01)
until resistance patterns came back ,along with
Rifampin, PZA, ETH, and Vit. B. - Original cultures showed MTB resistant to INH.
- Pt then received (8-9-01 to 10-9-01) Levoquin 500
QD, Rifampin, PZA, ETH, and Vit B6 for 2 months. - Pt then received (10-10-01 to 12-10-01) LEV, RIF,

ETH, and Vit. B6 for 1 month. - Pt then received (1-3-02 to 9-19-02) PZA, ETH,
LEV and Vit B6 for 9 months - Pt. had positive sputums for 4 months after
starting treatment, but the cultures never grew
anything.
98Case AD Treatment
- What does it mean that the patient had positive
sputums for 4 months, but the cultures were
repeatedly negative? - Patient was coughing up dead bacterium for months.
99Case AD Follow-up
- Patient was cured of active tuberculosis but
continued to smoke and died of end-stage lung
disease in 2005 at age 53.
100Case AD Key Take Home Points
- Resistant TB exists in the US
- Homelessness is a risk factor for TB
- Alcoholism is a risk factor or TB
101Case 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,
increasing fevers, weight loss, night sweats,
increased sputum production, SOB and right leg
pain. Long history of smoking, but quit several
years before. Unsure if having hemoptysis as
nearly blind and didnt see well. Family had
noticed large weight loss in previous 3 months.
Had been seen at SLRMC ER on 12/30 with similar
complaints and sent home. - PMH
- 1. () Diabetes on oral meds,
- 2. s/p below the knee amputation for poor
circulation in 6/03 - 3. () legally blind in both eyes from cataracts
and surgery - 4. High Cholesterol
102Case CN Treatment and Follow-up
- Pt. hospitalized from 1/20 until 1/27. Multiple
AFB smears came back positive for acid-fast
organisms. Drug therapy (4 drug INH, RIF, ETH,
and PZA from 1/22/04 until 3/10/04 3 drug
therapy INH, RIF, PZA from 3/11 until 3/25 2
drug therapy from 3/26 until 5/27). - Culture of mycobacteria did grow M TB in the
state lab. - Pt. was rehospitalized from 2/10 until 2/20 at
SLRMC for wasting and malnourishment. Peg Tube
placed. - Patient got 4 months of treatment. Moved back to
Mexico and took 1 month of meds with him
Contact made with hospital in Mexico. - He has not resurfaced in Sioux City since 2004.
103Case 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.
104Case DW MH 318507
- DW is a 60 year old man who presented to the SCHC
in May 2002. He was a known diabetic and
hypertensive who had been out of care for 3 and ½
years. He made his way to an ENT physician who
saw him for a hoarse voice and sore throat of
several months duration. He was taken to
surgery. He was referred for primary care
follow-up of his multiple medical problems. to
the office with hoarse voice and sore throat for
several months. Patient denied any cough, fever,
night sweats. - PMH, 1. () Diabetes, A1C 8.8
- 2. () chronic alcoholism,
- 3. () COPD,
- 4. () HTN,
105Case DW Treatment and FollowUp
- Multiples sputums came back positive for
acid-fast bacilli which were subsequently
identified as M. Tb at the state hygenic lab. - Patient was started on 4 drug therapy including
INH 300 QD, Rifampin 600 QD, Pyrazinamide 1500
QD, and Ethambutol 1600 QD Also vitamin B6,
Glucophage (for diabetes), HCTZ and Accupril (for
hypertension), and an ASA QD (for CAD
prophylaxis). - PT did 2 months of 4 drug TB therapy 4 further
months of INH and Rifampin Sputums and cultures
turned negative for M. TB and X-Ray normalized.
Patient was cured of active TB. - PT did however continue to drink alcohol heavily.
106Case DW Follow-Up
- 1 year from start of diagnosis, patient developed
epigastric pain EGD was done and biopsy of
Esophageal lesion showed Adenocarcinoma
(Barretts esphagus). Further workup showed
metastases in the liver. Patient lived several
months and died of metastatic esophageal cancer.
107Case 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. - You can still have active TB in a pt. with a
negative PPD. - Homelessness/poor living conditions are a flag
for TB
108Case HN MH 082144
- H. N. was a 49 year old African American man who
presented to the MHC ER on January 29th, 2004
with fever, cough productive of brown phlegm,

Streptomycin shots for 18 months, at the
suggestion of the Iowa state TB specialist. - Pt. continued with routine hearing screening and
vision screening (semi-compliant) while on
Ethambutol.
115Case CR Take-Home Points
- Inner-cities and prisons are both high-risk
locales for TB. - TB treatment can be complicated by resistance,
underlying medical conditions (nephropathy), and
non-adherence. - TB meningitis can present with headache.
- TB can present in multiple sites simultaneously-
here lung and CNS.
116Case J C-D SL 17416196

2/19/03 (INH, RIF) - Thus, patient got multi-drug therapy for about 8
months
119Case J C-D Follow-up
- Patient did well and moved away from the
community. About 2 years later, ca. 2004-5, I
met his niece in Sioux City and she said he was
alive and well in Florida.
120Case 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.
121Case 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.
He denied SOB, fevers, chills, sweats or weight.
He had had some recent pleuritic-type chest pain
which is worse with cough. - PMH No previous hospitalizations or surg.

mediastinal mass.
123Case SS Treatment
- Repeat CT scan was done after 6 months with total
disappearance of the mass. - Patient is alive and well in Siouxland.
124Case 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.
125LG 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.
126LG- 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.
127LG- 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.
128TB 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.
129TB 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.
130Take 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.
131Case 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.
132Case 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
133Case 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
134Mycobacteria 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.
135Mycobacteria 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
136Mycobacteria 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.
137Mycobacteria 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.
