Friend describes trying to help girl

One friend said the girl's companions weren't aware of the allergy beforehand.
MONTREAL (AP) -- Thinking she was having an asthma attack, Christina Desforges burst into a friend's room and woke him in a desperate search for medicine.
Friends called an ambulance as her breathing grew labored, but Desforges collapsed a moment after she stepped outside. She died four days later.
It quickly became clear the 15-year-old girl succumbed to a peanut allergy -- not from nuts she ate, but a peanut-butter sandwich her boyfriend had consumed before kissing her that day.
A friend of the couple's said in a television interview that Desforges' boyfriend and other companions had no idea she was allergic to peanuts. An allergist said Wednesday that the teenager's friends and relatives should have been warned about her condition.
"Some people have an extremely low threshold," said Dr. Rhoda Kagan, an allergist at Montreal Children's Hospital. "This varies greatly from person to person and is highly unpredictable."
She called Desforges' case "very rare and worrisome."
Friend's thoughts
One friend, Michael St. Gelais, said he was devastated by the case.
"I felt guilty at first because if I had realized earlier she was [allergic], we could probably have saved her," he said in an interview with Canadian Broadcasting Corp. "However, we did as much as we could and I don't think there was more we could have done."
Desforges, who lived in Saguenay, about 155 miles north of Quebec City, was almost immediately given a shot of adrenaline, a standard tool for treating anaphylactic shock brought on by an allergy to peanuts. But she died Nov. 23 at a Quebec hospital.
Symptoms of peanut allergies can include hives, plunging blood pressure and swelling of the face and throat, which can block breathing.
"There are several images stuck in my mind," St. Gelais said. "We went upstairs because she really was having more difficulty breathing. The minute we went outside, she collapsed."
A memorial took place Saturday and an autopsy was being performed Wednesday.
Desforges' mother declined to talk to The Associated Press.
