Fear of repeated injections in children younger than 4 years receiving subcutaneous allergy immunotherapy.

ABSTRACT: Allergy immunotherapy during early childhood may have potential benefits for the prevention of asthma and allergy morbidity. However, subcutaneous immunotherapy has not yet been prospectively researched in children younger than 4 years, primarily because of safety concerns, including the fear and psychological distress young children may experience with repeated needle injections.To quantify fear in atopic children younger than 4 years with a history of wheezing who are receiving subcutaneous immunotherapy.Fear of injection was graded during a total of 788 immunotherapy injection visits in 18 children (age, 37 months; SD, 9 months) receiving subcutaneous allergy immunotherapy. The parent and the injection nurse assigned fear scores on a scale of 0 to 10 after each injection visit.At the time of analysis, children had a median of 49 injection visits (range, 12-88) during a median study period of 81.5 weeks (range, 15-165 weeks). Fifteen children (83%) lost their fear of injections during the study. A fear score of 0 was achieved after a mean of 8.4 visits (SD, 7.4). The more injection visits were missed, the more likely children were to retain fear of injections (hazard ratio, 0.13; 95% confidence interval, 0.02-1.02; P=.05). Age, adverse events, number of injections at each visit, and change of injection personnel were not associated with increased fear.Our analysis suggests that most children receiving weekly subcutaneous immunotherapy lose their fear of injections during the treatment course. Children with increased intervals between visits may be at higher risk of experiencing fear of injections.clinicaltrial.gov identifier NCT01028560.

Project description:For egg allergy, dietary avoidance is the only currently approved treatment. We evaluated oral immunotherapy using egg-white powder for the treatment of children with egg allergy.In this double-blind, randomized, placebo-controlled study, 55 children, 5 to 11 years of age, with egg allergy received oral immunotherapy (40 children) or placebo (15). Initial dose-escalation, build-up, and maintenance phases were followed by an oral food challenge with egg-white powder at 10 months and at 22 months. Children who successfully passed the challenge at 22 months discontinued oral immunotherapy and avoided all egg consumption for 4 to 6 weeks. At 24 months, these children underwent an oral food challenge with egg-white powder and a cooked egg to test for sustained unresponsiveness. Children who passed this challenge at 24 months were placed on a diet with ad libitum egg consumption and were evaluated for continuation of sustained unresponsiveness at 30 months and 36 months.After 10 months of therapy, none of the children who received placebo and 55% of those who received oral immunotherapy passed the oral food challenge and were considered to be desensitized; after 22 months, 75% of children in the oral-immunotherapy group were desensitized. In the oral-immunotherapy group, 28% (11 of 40 children) passed the oral food challenge at 24 months and were considered to have sustained unresponsiveness. At 30 months and 36 months, all children who had passed the oral food challenge at 24 months were consuming egg. Of the immune markers measured, small wheal diameters on skin-prick testing and increases in egg-specific IgG4 antibody levels were associated with passing the oral food challenge at 24 months.These results show that oral immunotherapy can desensitize a high proportion of children with egg allergy and induce sustained unresponsiveness in a clinically significant subset.
