Doctors have issued a warning over vaping after a British teenager almost died from serious respiratory failure linked to e-cigarettes.
Ewan Fisher, 19 , was treated at Nottingham University Hospitals NHS Trust for “catastrophic” respiratory failure and ended up on life support.
He was under age when he purchased vaping equipment over the counter from a local shop and had been vaping for four to five months before he was taken ill aged 16.
Ewan was treated for hypersensitivity pneumonitis (HP) which is a type of allergic reaction to something breathed in which results in inflammation of the lung tissue.
He became so ill that he was put on a type of life support, extra corporeal membrane oxygenation (Ecmo), which is an exterior artificial lung that puts oxygen into the blood and pumps it around the body.
Writing in the journal Archives of Disease in Childhood, doctors said the “previously well young person presented with a catastrophic respiratory illness” which put his life in danger.
Dr Jayesh Mahendra Bhatt, a consultant in paediatric respiratory medicine at Nottingham University Hospitals NHS Trust, who treated Ewan, told the PA news agency: “The evidence we gathered showed that it was that (vaping) that was to blame.
“I know at least one colleague who has seen a similar case.”
Scientists are becoming increasingly divided over whether vaping causes harm to human health.
While evidence continues to be published on risks associated with vaping, Public Health England (PHE) stands by its claim that vaping is 95per cent less harmful than smoking.
It says non-smokers should not try vaping, but smokers would be far healthier if they made the switch to e-cigarettes.
In the new study, doctors said Ewan, a previous smoker, was admitted to hospital following a week of fever, a persistent cough and increasing difficulty with breathing.
His condition deteriorated rapidly and he developed respiratory failure, and was put on Ecmo plus intravenous antibiotics and steroids.
Ten days later, his condition became critical and he developed severe muscle weakness, requiring a long period of rehabilitation.
The teenager told medics “he had recently started to use e-cigarettes fairly frequently, using two different liquids, purchased over the counter”.
The listed ingredients for both vaping liquids were the same apart from the unnamed flavourings.

Ewan told doctors he had smoked cannabis a year previously but not recently.
After two months, he was still suffering and so skin tests were taken with vaping fluid, which made his symptoms worse.
Blood samples also showed that he had more antibodies to one of the two liquids, raising the possibility this might have been the source of his reaction. After 14 months, Ewan eventually recovered.
The doctors said: “There are two important lessons here. The first is always to consider a reaction to e-cigarettes in someone presenting with an atypical respiratory illness. The second is that we consider e-cigarettes as ‘much safer than tobacco’ at our peril.”
British Lung Foundation medical director Dr Nick Hopkinson said the findings showed it was “possible the patient’s illness could have been due to an allergic response to a component of e-cigarette vapour”.
However, he said it can often be difficult to make an accurate diagnosis for this condition.
“In Britain, 3.6 million people vape and youth use remains low,” he added.
“If this was a common problem or a significant risk we would expect many more cases.
“Advice remains that smoking carries a huge health risk and smokers need to quit if at all possible.”
Rosanna O’ Connor, director of drugs, alcohol, tobacco and justice at Public Health England, said: “We continue to keep the evidence under review, including all safety and health concerns reported to the e-cigarette regulator, the Medicines and Healthcare products Regulatory Agency (MHRA).
“However, smoking kills half of life-long smokers and accounts for almost 220 deaths in England every day.
“Our advice remains that while not completely risk free, UK regulated e-cigarettes carry a fraction of the risk of smoked tobacco.
“This view is held by many across the world, including the Royal College of Physicians, Cancer Research UK, the British Medical Association and the National Academy of Sciences in the US.”–PA
