Ontario reports 2 new 'probable' cases of vaping-related illness

Ontario hospitals have reported two new probablecases ofsevere pulmonary illness related to vaping one in Woodstock and another in Burlington Ontario's health ministry confirms.

Ontario health officials also confirm that a near-fatal casein London, Ont., publicized by the local health unitin September meets the Health Canada definition of the disease.

This brings to 11the number of confirmed or probable cases reported by Health Canada.

The two probable Ontario cases were reported after the province mandated in Septemberthat all publichospitals notify the chief medical officer in cases where they suspect a diagnosis of vaping-related severe pulmonary disease.

One case was reported by Joseph Brant Hospital in Burlington; the other at Woodstock General Hospital.

Health ministry spokesperson Travis Kannsaid in the two Ontario cases listed as probable, both patients have been discharged from hospital.

Citing patient privacy, he would not provide more details about the probable cases, including the severity of their symptoms.

Officials with the Middlesex-London Health Unit (MLHU)which went public with details about the London case in Septemberhave been awaiting official word from the province to confirmthe diagnosis as vaping-related

Dr. Chris Mackie, MLHU'smedical officer of health, said it's crucial the province movequickly to report confirmed details about cases as doctorswork to learn more about the health effects of vaping.

"I'm happy to see this confirmed," said Mackie. "It's good to see the province moving this file ahead."

A study published Thursday in the Canadian Medical Association Journal (CMAJ) contained new details about the London case.

The patient in the London case hasn't been identified, but the CMAJstudy says the otherwise healthy 17-year-old turned up at a local emergency room with a severe cough, shortness of breath and fever.

The teen vaped heavily in the months leading up to his illness. He spent 47 days in hospital and at one stage of his treatment wason life support.

He is now recovering at home but may have permanent lung damage.

"[The CMAJ report]makes a lot of case details public and helps the medical community understand the details of what they're seeing, the importance of this can't be overstated," said Mackie. "This really helps us to understand the risks and to be more aware in the medical community about this issue."

He said it's particularly concerning that in the London case cited in the CMAJ report, the patient wound up with a life-threatening condition after vaping only a few months.

Another concern is that CT scans of the patient in the CMAJ study show patterns of severe inflammation in the lungs.

"It looks like someone has taken a shotgun loaded with birdshot to these lungs," said Mackie. "This short term illness is not something we see with smoking.That is something that we now know can be associated with vaping."

Severe lung damage flagged in CMAJ study

Mackie points out that while the vaping industry often claims its products are safer than smoking cigarettes, there simply isn't enough information to confirm this.

"When you start smoking, it can take years or even decades to have a very serious impact on your life," he said. "Whereas in these situations we're seeing after just a few months life-threatening, and in some cases in the U.S., life-ending effects from vaping within a few months."

Health officials have warned that vaping products use marketing that targetsyoung people.
