Acute hypersensitivity pneumonitis found in user of e-cigarettes: Case study

More evidence is growing regarding the dangers of e-cigarettes, and now the latest findings show cases of acute hypersensitivity pneumonitis in users. The findings come from researchers at the VA Hospital in White River Junction, Vermont. The researchers report that they have found cases of acute hypersensitivity pneumonitis related to e-cigarettes and flavored e-cigarettes with the ingredient diacetyl.

The case study involved a 60-year-old cigar smoking male who was admitted to the hospital with chills, fever and a cough. After three days of treatment with ceftriaxone and azithromycin, the gentleman was discharged and went home feeling normal once again.

After a month’s time, the gentleman had the same symptoms once again. He presented a fever as well as hypoxemic – a condition where the body is oxygen deprived. A chest CT revealed he had bilateral upper lung zone crackles and bilateral upper lobe predominant ground glass opacities. With further questioning the patient revealed he was a heavy user of flavored e-cigarettes.

Diagnosis was inhalation injury as well as acute hypersensitivity pneumonitis associated with the use of the e-cigarette. After his second visit the patient stopped use of the e-cigarettes and the symptoms did not return. After a three-month follow up, a chest CT revealed everything was back to normal.

Lead researcher, Dr. Graham Atkins, said, “The use of e-cigarettes in the United States is increasing rapidly and the flavorings used, many of which contain diacetyl, may be harmful. This case adds to the growing body of research indicating e-cigarettes pose a health risk.”

The findings will be shared during the CHEST 2015 conference in Montreal, Canada on October 27th.
