Help, Doc! My Asthma/COPD Is Still Wheezing.
Case #1:Obstructive Lung Dz Mngmt
A 55 year old man who has a history of COPD, OSA, CAD, CKD, jaundice, & childhood asthma admitted for dyspnea. He is still wheezing & hypoxemic despite 5 d steroids & antibiotics. What do you do next?
a. Order Th2 genotype testingb. Treat empirically for PEc. Order inpatient PFTsd. Order Chest CT to rule-out other causes

❏ When to just start empiric tx of asthma or COPD?❏ “Classic cases”
❏ For everyone else, PFTs are very helpful❏ Spirometry - FEV1, FVC, FEV1/FVC ratio -
with bronchodilator response❏ Full PFT - Includes TLC & DLCO
PFTs: Low-Risk and High-Yield!

Key Point
Don’t let the bronchodilator reversibility overly sway you. COPD pts can have some BD responsiveness, and asthma pts can show no responsiveness.
Key Point
All that wheezes is not asthma...nor COPD! Keep your ddx very broad and think outside the [lung] box.

Common Asthma & COPD Mimics - Can Delay Dx
❏ Vocal cord dysfunction❏ Allergic bronchopulmonary
aspergillosis❏ Vasculitides such as
Eosinophilic Granulomatosis with Polyangiitis
❏ Infections such as Strongyloides
❏ Pulmonary embolism❏ Decompensated CHF❏ Obesity❏ Bronchiectasis❏ Occupational/environment
al lung diseases❏ Malignancy (lung or mets)❏ Interstitial lung diseases
What about Reactive Airways Disease?
Different from Reactive Airways Dysfunction Syndrome -
Acute wheezing in response to inhaled irritant

Diagnostically, When to Refer? Anytime if:
❏ Basic diagnostics are not helpful (PFTs, Chest CT)❏ You need advanced testing (e.g.
methacholine/bronchoprovocation testing, exercise testing, bronchoscopy, etc.)
❏ You suspect an asthma/COPD mimic❏ You just need extra diagnostic help!
Therapeutically, When to Refer? Anytime if:
❏ Severe asthma requiring ICU stay❏ Uncontrolled asthma despite step-up therapy❏ You are considering omalizumab or other IgE-mediated tx❏ You suspect an asthma mimic

Key Point
ICU Admission for asthma and intubation are strong predictors for fatal or near-fatal asthma. These patients can die before they reach the hospital.
Key Point
Don’t forget non-pharm management: smoking cessation, pulmonary rehab, trigger avoidance, exercise, flu vaccine & Pneumovax.

Steroids in Septic Shock: The Swinging Pendulum
❏ Current guidelines: Use hydrocort in septic shock if adequate fluid resuscitation & vasopressors haven’t restored HD stability...but weak rec based on low evidence
❏ 10 years ago, CORTICUS Trial of NEJM 2008 - now ADRENAL in NEJM 2018
❏ Second line of the editorial:❏ “Glucocorticoids have been used as an adjuvant therapy for
septic shock for more than 40 years.”

❏ ADRENAL randomized 3685 pts w/ septic shock to continuous IV infusion of hydrocortisone (200mg/24 hrs) vs. placebo
❏ NO difference in 90-day mortality (~28% in both groups)❏ Lower # of days on pressors (3 vs. 4)

Case #3: Management of Recurrent Pleural EffusionsA 65 year old woman is readmitted for pleural effusion of unknown etiology. Last thoracentesis had negative cytology & cx. You:
a. Repeat the thoracentesisb. Refer for pleurodesisc. Refer for pleural biopsyd. Place a PleurX catheter
Dig Deep to Find an Etiology, Since Diff Mngmt❏ Never place a chest tube to drain hepatohydrothorax.❏ Consider serial drainage + diuretics for recurrent transudates❏ If drainage slows but effusion persists:
❏ Consider reimaging: loculation? tube position?❏ Consider TPA and DNAase
❏ If chest pain with chest tube beyond expected:❏ Consider: tube dysfunction/malpositioning?❏ Consider complications like infxn, lung lac,
diaphragm injury, reexpansion pulm edema
