Safety of sublingual immunotherapy started during the pollen season
Sublingual immunotherapy (SLIT) is safer than subcutaneous immunotherapy (SCIT) and this has lead to the reconsideration of the use of ultra-rush schedules for SLIT. The aim of this study was to assess the safety of ultra-rush SLIT in pollen-allergic children according to different timing of administration in relation to the pollen season.In total, 34 children with pollen-induced rhinitis and 36 with pollen-induced asthma and rhinitis, were enrolled and assigned to three study groups: group 1 (n = 17 patients): conventional pre-seasonal-SLIT treatment; group 2 (n = 23 patients), seasonal SLIT ended before the pollen seasonal peak; group 3 (n = 30 patients), SLIT began after the pollen seaso…
Safety of sublingual-swallow immunotherapy in children aged 3 to 7 years
Background The minimum age to start specific immunotherapy with inhalant allergens in children has not been clearly established, and position papers discourage its use in children younger than 5 years. Objective To assess the safety of high-dose sublingual-swallow immunotherapy (SLIT) in a group of children younger than 5 years. Methods Sixty-five children (51 boys and 14 girls; age range, 38-80 months; mean ± SD age, 60 ± 10 years; median age, 60 months) were included in this observational study. They were treated with SLIT with a build-up phase of 11 days, culminating in a top dose of 300 IR (index of reactivity) and a maintenance phase of 300 IR 3 times a week. The allergens used were ho…
Comparison of ammoniated and nonammoniated extracts in children with latex allergy
Background: The use of ammoniated or nonammoniated latex extracts for the diagnosis of latex allergy is still a matter of debate. The aim of our study was to compare the characteristics of the two types of extracts by immunoblotting and RAST techniques in children with ascertained latex allergy. Methods: Ammoniated (AL) and nonammoniated latex (NAL) extracts were prepared and blotted on SDS-PAGE to resolve their components. Also a solid phase for RAST assays was prepared with the two extracts. The sera from 18 children (mean age 11.4 years, range 6–15 years), with ascertained latex allergy (clinical history, skin test, CAP-RAST and provocation) were used for the experiments. Results: The…
CD4(+)IL-13(+) cells in peripheral blood well correlates with the severity of atopic dermatitis in children.
BACKGROUND In atopic dermatitis (AD) a Th1/Th2 imbalance has been reported, and interleukin (IL)-13 seems to play a pivotal role in the inflammatory network. We tried to assess the correlation between the immunological marker CD4(+)IL-13(+) and the clinical phase of extrinsic AD in children. METHODS Twenty children with AD were studied. Assessed parameters were: clinical severity (SCORAD index), total serum immunoglobulin E (IgE), blood eosinophil count, and percentage of CD4(+)IFNgamma(+), CD4(+)IL-4(+), CD4(+)IL-13(+) T cells. Determinations were carried out in the acute phase and after clinical remission were achieved. Ten nonatopic-matched children served as controls. RESULTS At baselin…
