Allergies Linked to Lower Brain Cancer Rate in Study
Posted 7 Feb 2011 by Drugs.com
MONDAY, Feb. 7 – If you suffer from allergies, take heart: Researchers say you may be less likely to develop a tough-to-treat brain cancer, possibly because your immune system is on high alert. It's not clear how this knowledge might improve prevention or treatment of brain cancer, but the study's lead author said the findings pave the way for further research. "We need to do more studies to really get at that underlying mechanism. Then we might be able to do things that would influence people who might have a higher risk or may have a family history," said Bridget J. McCarthy, a research associate professor of epidemiology at the University of Illinois at Chicago. The lesions studied are known as gliomas, the most common type of adult brain tumor. They account for more than half of the 18,000-plus malignant brain tumors diagnosed in the United States every year, according to the U.S. ... Read more

Meat Might Be Behind Many Unidentified Allergic Reactions
Posted 1 Mar 2010 by Drugs.com
SUNDAY, Feb. 28 – A carbohydrate in meat called alpha-gal may be the unrecognized cause of recurring severe allergic reactions in some patients, a new study suggests. The study included 60 people in Australia and the United States who experienced the recurrent severe allergic reaction known as anaphylaxis with no known cause. Allergy tests revealed that 25 of the 60 patients had positive responses to alpha-gal. A positive response was considered a level of greater than 1.0 international units per milliliter of immunoglobulin E (IgE). The tests did not identify any other allergens that would explain the cause of anaphylaxis in the 25 patients who were positive for alpha-gal or in the other 35 patients, the study authors noted. The findings were scheduled to be presented Sunday at the American Academy of Allergy, Asthma & Immunology annual meeting, in New Orleans. "These studies continue ... Read more

Penicillin Allergy Might Not Include Related Antibiotic
Posted 27 Feb 2010 by Drugs.com
SATURDAY, Feb. 27 – Most patients who have a history of penicillin allergy can safely take antibiotics called cephalosporins, U.S. researchers say. Cephalosporins – which are related to penicillin in their structure, uses and effects – are the most frequently prescribed class of antibiotics. "Almost all patients undergoing major surgery receive antibiotics to reduce the risk of infections. Many patients with a history of penicillin allergy don't get the cephalosporin because of a concern of possible drug reaction. They might get a second-choice antibiotic that is not quite as effective," study author Dr. James T. Li, of the Mayo Clinic in Rochester, Minn., said in a news release from the American Academy of Allergy, Asthma & Immunology. He and his colleagues conducted penicillin allergy skin tests on 178 patients who reported a history of severe allergic (anaphylactic) reaction to ... Read more

Kids' Peanut Allergies Might Be Tamed: Study
Posted 27 Feb 2010 by Drugs.com
SATURDAY, Feb. 27 – Help may be on the way for children with serious peanut allergies, with two new studies suggesting that slowly increasing consumption might build kids' tolerance over time. Both studies were small, and designed to build upon each other. They focused on peanut-allergic children whose immune systems were prompted to slowly develop tolerance to the food by consuming a controlled but escalating amount of peanut over a period of up to five years. "The current goal with this work is not to allow patients with peanut allergies to consciously eat peanuts, but to prevent the severe symptoms that can occur should they have accidental ingestion," noted study co-author Dr. Tamara Perry, an assistant professor of pediatrics at the University of Arkansas for Medical Sciences College of Medicine in Little Rock, Ark. "Of course the ultimate goal would be to promote tolerance that ... Read more
