The 2011 Annual Meeting of the American College of Allergy, Asthma & Immunology

The annual meeting of the American College of Allergy, Asthma & Immunology was held from Nov. 3 to 8 in Boston, and attracted more than 3,500 participants from around the world, including allergy and immunology specialists as well as other health care professionals. The conference featured presentations focusing on the latest advances in the prevention and treatment of asthma, food and medication allergies, immune dysfunction, and sleep apnea.

Jacqueline Ross, M.D., of the University of Michigan Health System in Ann Arbor, and colleagues found that both self-reported depression and depression found through a validated screening tool was associated with poorer asthma quality-of-life and worse asthma control in older adults (over 65 years of age).

"While traditional indicators of poor asthma control, including number of hospitalizations, unscheduled visits, and number of attacks, were also associated with lower quality of life and asthma control among older adults in our study, comorbid depression appeared to be a major contributor to these outcomes as well," Ross said. "In conclusion, the results of this study suggest that, although other asthmatic populations may benefit most from aggressive treatment of asthma severity, the older asthmatic likely requires a more integrative approach in treatment. If we treat the physical aspects of the disease, as well as the psychological and social aspects, we may find greater success in asthma control and improved quality of life for these individuals."

In another study, Matthew Greenhawt, M.D., also of the University of Michigan Health System in Ann Arbor, and colleagues found that a single dose of the trivalent seasonal flu vaccination may be safe for children with egg allergy.

"The investigators found that splitting the doses of flu vaccine into two doses, administering 20 percent of the dose, waiting a few minutes and then giving the rest of the dose (if no reaction occurred) was generally safe. In addition, they also found that administering the vaccine completely in one dose under the supervision of an allergy specialist was equally safe and well tolerated," said Gailen D. Marshall Jr., M.D., Ph.D., editor-in-chief of the Annals of Allergy, Asthma & Immunology. "At this point, it can be recommended to administer the flu vaccination in children with egg allergy under close medical supervision. The authors did not recommend that children with egg allergy be administered the vaccine without close office observation but it is likely that will occur in the future, as the amount of egg in the flu vaccines is relatively uniform across the board and the amount of egg protein within the vaccines is getting less and less."

Terri Moncrief, M.D., of the Cincinnati Children's Hospital Medical Center, and colleagues found that children with asthma from homes with single parents were 50 percent more likely to revisit the emergency room or be rehospitalized within 12 months of an index hospitalization as compared to children from dual-parent households.

"There were four variables we evaluated, including mobility of the child (routine care outside the home), psychological strain on the primary caregiver (high score on a screen for mental illness), time strain (higher ratio of children to adults in the household), and income strain (lower annual household income)," Moncrief said. "We found a significant difference between homes of single and married parents with respect to each of the strains. In particular, income strain and time strain were associated with an increased likelihood of repeat health care use."

ACAAI: Statin Treatment Tied to Worse Asthma Control

MONDAY, Nov. 7 (HealthDay News) -- The use of cholesterol-lowering statin drugs by patients with extrinsic asthma may worsen their asthma control, according to a study presented at the annual meeting of the American College of Allergy, Asthma & Immunology, held from Nov. 3 to 8 in Boston.
