    Notes: Celiac disease (CD) and chronic urticaria (CU) are both sustained by immune mechanisms, but there are so far few data on their clinical association. We performed a case–control study to determine the occurrence of CD in urticaria and matched control children, and to assess the clinical relevance of this association. Children and adolescents were diagnosed to have severe chronic idiopathic urticaria in the presence of hives for more than 6 wk poorly or not responsive to oral antihistamines. Other known causes of urticaria had to be excluded. A matched control group without urticaria was enrolled. In both groups, the presence of CD was searched by assaying antitransglutaminase and antiedomysial antibodies, and confirmed with endoscopic intestinal biopsy. Results. CD was diagnosed and confirmed in 4/79 (5.0%) of children with CU and in 17/2545 (0.67%) of the controls (p = 0.0003). In the four children with urticaria and CD the gluten free diet (GFD) lead to complete remission of urticaria within 5–10 wk, whereas the disappearance of serological markers occurred in longer times (5–9 months). Conclusions. The presence of CD in children with CU was significantly more frequent than in controls. GFD resulted in urticaria remission. CD may be regarded in such subjects as a cause of CU.

    Notes: Background Immunotherapy is a recognized treatment for allergic respiratory diseases.Objective To study the usefulness of immunotherapy in combination with optimal pharmacological therapy.Methods Thirty-eight children (8–14 years) suffering from seasonal asthma±rhinoconjunctivitis due to Parietaria poorly controlled by anti-allergic drugs treatment were selected. After randomization according to a double-blind placebo-controlled design they received active sublingual immunotherapy (15 children) or placebo (15 children) for 13 months combined with inhaled fluticasone twice a day during the pollen season. Eight children were taken as control, whereas all patients were instructed to take symptomatic drugs on need. Early and late skin response to the allergen were assessed in all patients before and after treatment. Drug and symptom scores, as well as visual analogue scores (VASs) and Parietaria pollen counts were assessed during the pollen season.Results Groups were well balanced for age, gender, early and late skin response before treatment. Four children dropped out, in one case in relationship with active sublingual immunotherapy (SLIT) administration. Chest and nose symptoms, as well as drug scores and VASs were significantly better in both the active or placebo SLIT+fluticasone (S+F) as compared to the control group (P between 〈0.001 and 0.043). Eye symptoms were significantly better in the active S+F group as compared to control (P=0.025). The VASs were significantly better in the active S+F group as compared to the placebo S+F group (P=0.037). The early skin response decreased significantly in the active S+F group (P〈0.001), whereas the late skin response changed significantly in all groups, with an increase in the placebo+fluticasone group (P=0.019) and in the control group (P=0.037) and a decrease (P〈0.0001) in the active S+F group.Conclusion The clinical efficacy of S+F is equal to that of fluticasone alone, but the addition of SLIT has effects also on non-bronchial symptoms.

    Sublingual immunotherapy abrogates seasonal bronchial hyperresponsiveness in children with Parietaria-induced respiratory allergy: a randomized controlled trial (2004)

    Notes: Background:  The use of immunotherapy in asthmatic children is still controversial. Sublingual immunotherapy (SLIT) may represent an advance, due to the good safety profile, but little is known about its effects on lung function and nonspecific bronchial responsiveness.Objective:  The aim of this study was to assess the effects of SLIT on these parameters, in children with Parietaria pollen-induced asthma.Methods:  Thirty children with asthma solely due to Parietaria who participated in a previous randomized, placebo-controlled trial with SLIT were studied: pulmonary function test and methacholine challenge were carried out at baseline in winter 1999 (out season), during the 1999 season (before randomization), and during the 2001 season.Results:  Before randomization, there was a significant fall in methacholine provocation concentration during the pollen season vs baseline in both groups (SLIT group 9.78 ± 5.95 mg/ml vs 3.37 ± 2.99 mg/ml; placebo 8.70 ± 6.25 mg/ml vs 2.44 ± 2.25 mg/ml; P = .005). In the second pollen season, the response to methacholine returned to baseline values in the active group (9.10 ± 7.7 mg/ml; P = NS vs baseline), whereas in the placebo group a significant increase in reactivity was still present (2.46 ± 2.26; P = 0.008 vs baseline). No significant difference in FEV1 and FEF25−75 between the two groups was observed at all times.Conclusions:  Our data show that SLIT abrogates the seasonal bronchial hyperreactivity in children with asthma due to Parietaria. This may be regarded as an indirect evidence of the effect on bronchial inflammation.

    Molecular analysis of sequence variants in the Fcɛ receptor I β gene and IL-4 gene promoter in Italian atopic families (2004)

    Notes: Background:  The genetic variants in the Fcɛ receptor I β gene (Glu237Gly) and the T allele of the (C590T) polymorphism of interleukin (IL)-4 gene promoter were reported to be associated with atopy. But the data of the studies in different populations are contrasting with one another.Methods:  A group of 25 Italian nuclear families were studied. In each family at least two allergic subjects were present. The allergic children were 65 and the allergic relatives were 35. One hundred and three nonallergic unrelated controls included outpatiens with no history of atopy. The (C590T) promoter polymorphism of the IL-4 and the genetic variant Glu237Gly of Fcɛ RI β genes were analysed by the polymerase chain reaction-restriction fragment length polymorphism method.Results:  A significant difference was observed in the genotype frequency at codon 237 of the Fcɛ RI β gene between allergic children and nonatopic control (P 〈 0.01) and in the allergic relatives (P 〈 0.001). In the children, the Glu237Gly polymorphism was also associated with elevated circulating levels of immunoglobulin E. The -590C/T allele of IL-4 promoter gene showed no association with atopy.Conclusions:  In our study, the Glu237Gly polymorphism of the Fcɛ RI β gene was associated with atopy. Our results have not pointed out an association between the (C590T) promoter polymorphism of the IL-4 gene and atopy. These data suggest the potential role of the Fc RI β gene in the development of the allergy.
