Summary:
Researchers have shown that race and possibly genetics play a role in children's sensitivity to developing allergies. Researchers found: African-American children were sensitized to at least one food allergen three times more often than Caucasian children. African-American children with one allergic parent were sensitized to an environmental allergen twice as often as African-American children without an allergic parent.

Research conducted at Henry Ford Hospital shows that race and possibly genetics play a role in children's sensitivity to developing allergies. Researchers found:

  • African-American children were sensitized to at least one food allergen three times more often than Caucasian children.
  • African-American children with one allergic parent were sensitized to an environmental allergen twice as often as African-American children without an allergic parent.

The study will be presented February 23 at the American Academy of Allergy, Asthma and Immunology annual meeting,

"Our findings suggest that African Americans may have a gene making them more susceptible to food allergen sensitization or the sensitization is just more prevalent in African American children than white children at age 2," says Haejim Kim, M.D., a Henry Ford allergist and the study's lead author. "More research is needed to further look at the development of allergy."

Sensitization means a person's immune system produces a specific antibody to an allergen. It does not mean the person will experience allergy symptoms.

According to an AAAI study from 2009-2010, an estimated 8 percent of children have a food allergy, and 30 percent of children have multiple food allergies. Peanut is the most prevalent allergen, followed by milk and shellfish. 1The Henry Ford study consisted of a longitudinal birth cohort of 543 children who were interviewed with their parents and examined at a clinical visit at age 2. Data included parental self-report of allergies and self-reported race (African American or white/non-Hispanic). The children were skin-tested for three food allergens -- egg whites, peanuts and milk -- and seven environmental allergens.

Key findings:

  • 20.1 percent of African-American children were sensitized to an food allergen compared to 6.4 percent in Caucasian children.
  • 13.9 percent of African-American children were sensitized to an environmental allergen compared to 11 percent of Caucasian children.
  • African-American children with an allergic parent were sensitized to an environmental allergen 2.45 times more often than African-American children without an allergic parent.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
