Peaks and EVALIs
Vaping: The act of inhaling a vapor from a vaporizer
In contrast to smoking, which is burning a substance and inhaling it
You aren’t burning anything when you vape, just heating it
Routes to Vape
E-cigs: Simple, disposable devices pre-filled with some liquid - gives the feel of smoking a real cigarette
Vape pens: reusable don’t look like pens; you purchase refills for
Desktop Vaporizers/Vape mods: for enthusiasts; for people who want to control flavor, consistency and more
What Substances are in vaping fluid?
“Don’t tell me what I can vape”
E-liquids “vape juice” - may or may not contain nicotine
Dry herbs (usually marijuana)
Waxes/Oily concentrates (usually marijuana)
Vaporizing oily concentrates: “Dabbing”
Vitamin E acetate: fatty substance used to carry THC - may be associated with EVALI
epidemiology
Average age 28
Many are male
Of the reported cases, 82% vaped product with THC
Symptoms
Most common presenting symptoms: dyspnea, cough, chest pain, fever and chills, GI symptoms. URI symptoms have not been a feature, but fever, hypoxia are
Phenotypes/Radiology
Diagnosis
Confirmed
Vaping or dabbing 90 days before symptoms onset
Pulmonary infiltrate (laterality not specified)
Absence of pulmonary infection on initial work up
No alternative plausible diagnoses (like cardiac, rheumatologic, or neoplastic process)
Probable
Still have vaping or dabbing 90 days before symptom onset and pulmonary infiltrates
Still have no alternative plausible diagnosis
But here – pulmonary infection is identified on the initial workup
With the caveat being that the clinical team does NOT think that the pulmonary infection is the sole cause of the patient’s symptoms
Summary
Diagnostic criteria include
Hx vaping in past 90 days
Infiltrates
No alternative plausible diagnosis
We have confirmed cases (which have NO infection in the initial workup) and probable cases (which have an infection in the initial workup but the clinicians do NOT believe this is the sole cause of the patient’s presentation)
Don’t forget to incorporate questions on vaping in your routine history for all of your patients
Make sure you ask questions about what the patient vaporizes, where they get it, how much of it they vape, and if they add anything else in the mix
When working up these patients – perform your classic pneumonia workup. Add in ESR, CRP, HIV, and maybe a viral panel
Treatment is pretty uninspiring thus far – steroids, O2, and antibiotics
Report your case to your local health department
From a counseling standpoint, don’t start vaping, don’t switch back to smoking cigarettes
