Health officials said on Friday that a fifth person in the US has died from a mysterious lung illness linked to vaping.

There are now 450 possible cases in 33 states and one territory, five deaths, and one death under investigation.

Doctors and health officials in states with the earliest and largest number of cases have published detailed descriptions of the acute lung disorder in people who vape in a series of articles in the New England Journal of Medicine, describing the surge in cases as “worrisome”.

Officials said the definitive cause of the illness remains unknown.

However, “the severity of the illness and the recent increase in incidence of this clinical syndrome indicates that these cases represent a new or newly recognised and worrisome cluster of pulmonary diseases related to vaping”, according to a report by health department officials in Wisconsin and Illinois, who conducted a joint investigation of 53 patients.

The Centres for Disease Control and Prevention (CDC) warned that no consistent e-cigarette products have been linked to the disorder.

While some patients used marijuana-based products, some reported using marijuana and nicotine products and a smaller group reported using nicotine only.

“We are getting a clearer focus, and the investigation is narrowing,” said Ileana Arias, the acting deputy director for noninfectious diseases at CDC.

Officials said no specific device or substance has been linked to all the cases.

The Food and Drug Administration (FDA) is analysing samples collected from patients across the country who have fallen ill and testing them for a broad range of chemicals, including nicotine, THC – the active ingredient in marijuana that produces the high – and “cutting agents” to dilute solutions and other substances.

“We believe chemical exposure is likely associated with the illnesses,” said Dana Meaney-Delman, who is heading CDC’s lung injury response.

This week, New York state and FDA labs told officials they found vitamin E acetate, an oil derived from vitamin E, in samples of marijuana products collected from patients who had taken ill after vaping.

New York state officials have said the oil is a key focus of the state’s investigation.

FDA officials have stressed, however, that no one substance, including vitamin E acetate, has been identified in all samples.

And identifying compounds in samples will not necessarily answer questions about causality, they said.

The Indiana State Department of Health reported the state’s first vaping-related death this week.

The person died “due to severe lung injury linked to a history of e-cigarette use or ‘vaping’”, according to health officials.

The death was confirmed on Thursday and the patient was identified only as being over the age of 18.

On Friday, the Minnesota health department said a 65-year-old patient died in August due to lung injuries related to vaping. The patient died after a “long and complicated hospitalisation”, officials said.

Health authorities said on Friday they are investigating Los Angeles County’s first known death associated with vaping. Illinois and Oregon have also each reported a death.

The rising case counts drew an angry tweet from senator Dick Durbin, who threatened to call for the resignation of acting FDA chief Ned Sharpless.

Most patients have been young and healthy. They had similar symptoms, including a cough, chest pain or shortness of breath, which appeared to take place over several days to several weeks before hospitalisation, according to a CDC report released on Friday.

All patients reported using e-cigarettes, which officials define as battery-operated devices that heat a liquid and deliver an aerosolised product.

Clinicians in Utah and North Carolina said they had identified the presence of abnormal immune cells in the lungs of some patients, which could be a “useful marker” for a diagnosis of a rare form of pneumonia known as lipoid pneumonia, according to findings reported by University of Utah Hospital clinicians in the New England Journal of Medicine on Friday.

“That can occur when either oils or lipid-containing substances enter the lungs,” said Daniel Fox, a pulmonologist and critical care physician at WakeMed Health and Hospitals in North Carolina.

Dr Fox said he had treated five patients, and those cases were to be reported on Friday by North Carolina’s health department.

Mystery lung illness linked to vaping reported in nearly 100 people

In the joint investigation by Wisconsin and Illinois health departments, the earliest report of symptoms took place in mid-April.

Most of the 53 patients were young healthy men, with a median age of 19. All but three patients were hospitalised. More than half required intensive care.

One-third needed respirators to keep breathing. All used e-cigarettes or related products within 90 days of getting sick; a significant number reported vaping in the week before falling ill.

Around 84 per cent of the patients told doctors they used THC in e-cigarette devices. They reported using 14 different brands of THC products; the most common one was marketed under the “Dank Vape” label.

That label is sold online and industry sources say marketers often fill an empty cartridge with potentially unsafe ingredients and sell to unsuspecting customers.

Patients also reported using 13 brands of nicotine products in a wide range of flavours.

Fifteen patients said they only used THC products; seven said they used nicotine-only products, adding to the mystery of what exactly has caused healthy teenagers and young adults to suffer such severe injuries. Doctors have said that patients, especially teenagers, are often reluctant to say whether they have used marijuana products.

Health officials have said they are focusing on contaminants and counterfeit substances as a likely cause, narrowing the possible culprits to adulterants in vaping products purported to have THC, although they have not ruled out adulterants in nicotine vaping products.

E-cigarette aerosol generally contains fewer toxic chemicals than conventional cigarette smoke, officials have said. But e-cigarette aerosol is not harmless and can expose consumers to substances known to damage health, including ultra-fine particles, heavy metals, volatile organic compounds and other harmful ingredients.

Many of the chemicals in e-cigarette liquids may “undergo thermal degradation” when they are heated, producing new compounds with potentially harmful consequences.

“Alone or in combination, these substances could result in a variety of pulmonary illnesses,” the authors of the study on the Wisconsin and Illinois investigation wrote.

The illnesses could include lipoid pneumonia and could result in severe lung injury and a very serious condition known as acute respiratory distress syndrome.
