WEST PALM BEACH, Fla. _ Children who keep avoiding peanuts after they outgrow their peanut allergy have a higher risk that their peanut allergy will return, according to a study in this month's Journal of Allergy & Clinical Immunology.

For the study, Dr. David M. Fliescher of Johns Hopkins University School of Medicine and colleagues studied 68 patients who had previously outgrown their peanut allergy.

They wanted to determine the percentage of patients who reacquire peanut allergy later; identify any risk factors for recurrent peanut allergy; and develop specific recommendations for treating patients who have outgrown peanut allergy.

The researchers found that patients who have outgrown their peanut allergy have approximately an 8 percent chance of it reoccurring. The study found this risk is significantly higher in patients who continue to avoid eating peanuts after their allergy is resolved.

Based on the study's results, researchers recommend that patients eat concentrated forms of peanuts at least once a month after outgrowing their peanut allergy.

Stent's effect limited

While the placement of stents in newly reopened coronary arteries has been shown to reduce the need for repeat angioplasty procedures, researchers from the Duke Clinical Research Institute have found that stents have no impact on mortality over the long term.

Duke researchers said their findings have important economic and clinical implications for physicians who are deciding whether their heart patients should receive coronary artery bypass surgery, or less-invasive angioplasty, which includes the placement of a stent.
