This presentation was based on diagnosing a fictional patient, KB, here is the additional information from this particular presentation:
IAL Asthma Case
CC: “I need to refill my Ventolin”
KB is a 25-year-old female who presents to your community based asthma clinic for an evaluation. She reports, “My asthma has gotten so much worse since I’ve moved back up here. I’ve been waking up at night coughing and wheezing, plus I just can’t seem to get my errands done because I feel so out of breath for days after an attack”. Upon further questioning KB describes having symptoms of wheezing almost daily, with 2-3 exacerbations per week, along with a disrupted sleep pattern in which she wakes up about once a week with symptoms. KB brought a log of her peak flow readings from when she was in Miami, but she lost her PF meter during the move. Her personal best was estimated to be 485 L/min. She also states, “I’ve been going through my Ventolin like crazy, I really think I need another one”.

2. Epidemiology
• Asthma is classified as inflammation of the airways
leading to narrow passages and trouble breathing.
Patients usually have symptoms of coughing and
wheezing.
• 20 million Americans affected (1 in 15 americans)
• 50% of asthma cases are “allergic asthma”
• Asthma is the most common chronic childhood
disease and is also more common in children than
adults.

3. Patient Summary
• KB is a 25 y/o female that is presenting with
uncontrolled asthma and exacerbations. She wakes
up at least once a night with coughing a wheezing.
She finds it difficult to do errands after an attack
because she feels so out of breath. She is wheezing
daily and has 2-3 exacerbations per week.
• KB has recently moved from Florida and now lives in
an old apartment. She says that her asthma has
gotten worse after the move.
• Her personal best peak flow was 485L/min but her
4. Exams and History
• KB has had asthma since 1992. She has been hospitalized once and
has never been intubated.
• KB suffers from seasonal allergies (pollen and ragaweed). Also has
allergies to dried fruit, aspirin and peanuts
• Physical exam is normal expect she has a high respiratory rate of 20.
KB is unable to get air out of her lungs because of the asthma. Her
lungs also have bilateral wheezing.
• Family history is unimpressive
• In social history it should be noted that she lives an active lifestyle (so
the exacerbations may be exercise induced) and her asthma has
worsened upon moving.
5. Goals of Therapy
• Control KBs asthma
• Decrease frequency of exacerbations
• Decrease dependence on SABA
• Increase awareness of environmental and behavioral
factors
• Get KBs PEF in the green zone
• Streamline KBs medication regimen to better control
6. Medications
• Ventolin HFA 2puffs q4-6h prn
• Flovent HFA 110mcg 2puffs BID (last filled in 2009)
• Ibuprofen 200mg prn for headache
• Tums 2tablets qid prn for heartburn
• Ehinacea extract prn for onset of cold/flu

8. Classifying KB’s Asthma
• KB would be classified as having moderate persistent
asthma because she has daily symptoms and she
wakes up once a week from coughing and wheezing.
• KBs PEF cannot be determined because she lost her
peak flow meter
• We can help control KBs asthma by revamping her
medication regimen and suggesting some
environmental changes.
9. Environmental/Behavioral
Changes
• KBs asthma worsened when she moved into an old
apartment. Mold and dust from the apartment may
be aggravating her asthma. KB should dust
frequently and clean her pillows and blankets. KB
should even consider getting plastic allergen covers
for her furniture.
• Don’t go out on high pollen days.
• Take the Ventolin before exercise
10. Management of KBs Allergies
• KB is allergic to aspirin and is also taking ibuprofen.
Ibuprofen and aspirin come from the same derivative
so there may be cross reactivity.
• KB is also allergic to peanuts so we must take note of
the propellants used in some of the HFA inhalers.
Some of the propellants (in Combivent for example)
have are based in lecithin.

11. Medications
• KB has not been compliant with her ICS (Flovent)
which is used for long term chronic asthma.
• We suggest counseling KB on the importance of using
the ICS every day for chronic symptoms and using the
Ventolin for acute attacks only.
• Explain that the ICS must be taken daily even when
symptoms are clearing. Effects won’t be seen for 1-2
weeks with full effects in 4-8 weeks.
• Also cousel KB on the importance of not overusing
the Ventolin because it can lead to serious side effects.
12. Therapy Alternatives
• If KB still presents with uncontrolled asthma at
follow up consider the following:
• Oral corticosteroid burst therapy if exacerbations
persist
• Increase the dose of ICS (Flovent 88mcg -> 220mcg)
• Long Acting Beta Agonists in conjunction with ICS
• Leukotrine modifiers (salmeterol) because they are
good for exercise and allergy induced asthma.
13. Echinacea
• Echinacea is believed to be an immuno-stimulant.
• Asthma is a disease cause by an over-reactive immune
system.
• Additionally, asthma is treated by inhaled cortico-
steroids, which are immuno-suppressants.
• These factors all make the use of Echinacea illogical
during the treatment of asthma.
• Bottom line, strongly advise KB to discontinue echinacea.

14. Counseling Points
• KB may not be getting the most benefit from her inhaler. Counsel KB on how to
use the inhaler and encourage the use of a spacer

16. Summary
• Recommend thorough cleaning of KB’s new living
environment.
• Strongly advise discontinuing echinacea.
• Stress the importance of using the ICS everyday, even
when symptoms are clearing.
• Discontinue ibuprofen.
• Counsel patient on importance of compliance and
how to use an inhaler correctly
