The objective of the study is to verify effects of nebulized 3% saline hypertonic solution (HS) in comparison to normal saline (NS) in addition to epinephrine in hospitalized children with bronchiolitis. Infants were randomly assigned either to receive every 6 hours nebulized NS (group I) or 3% HS (group II) in addition to epinephrine (1.5 mg) and to conventional treatment. The main endpoints of this study were the length of stay (LOS) in hospital and the clinical response score (CSS). Patients presented a significant decrease in CSS from the first through the third day of treatment, present in the first group but even more evident in the second group (p=0.0001). Comparison between group I and II data shows significant decrease in CSS in the 3% HS-treated patients both at the second (p<0.005) and at the third day of treatment (p<0.005). Infants in the NS control group had a mean LOS of 5.6±1.6 days, whereas children treated with 3% HS were discharged with a LOS of 4.9±1.3 days, reaching a significant decrease in stay (p<0.05). In hospitalized patients bronchiolitis nebulized 3% HS and epinephrine significantly decreased symptoms and LOS as compared to 0.9% NS and epinephrine.

Allergic rhinitis is characterized by local inflammation. Nasal lavage may be a useful treatment, however, there are few studies on this topic. This study aims to evaluate the effects of Ischia thermal water nasal irrigation on allergic rhinitis symptoms and airway inflammation during the period of natural exposure to Parietariapollen in children with allergic rhinitis and intermittent asthma. Forty allergic children were randomly divided into two groups: the first group (Group 1) practiced crenotherapy with thermal water aerosol for 15 days per month, for three consecutive months, the control group (Group 2) was treated with 0.9% NaCl (isotonic) solution. In addition, all children were treated with cetirizine (0.5 gtt./kg/day once daily). Nasal symptom assessment, including Total Symptom Score (TSS), spirometry, and exhaled nitric oxide (FeNO) were considered before the treatment (T0), at the end of the treatment (T1) and again 2 weeks after the end of the treatment (T2). The study was registered in the Clinical Trials.gov(NCT01326247). Thermal water significantly reduced both TSS and FeNO levels and there was a significant relationship between reduction of nasal symptoms and FeNO values at the end of treatment with thermal water. In conclusion, this study shows that nasal crenotherapy with the hyper-mineral chloride-sodium water of Ischia was effective in children with seasonal allergic rhinitis based on the sensitivity to Parietaria. These results demonstrate that this natural treatment may be effective in a common and debilitating disease such as the allergic rhinitis.

We evaluated the bronchial hyperreactivity (BHR) with a new bronchial challenge test, mannitol dry powder, in a paediatric population with intermittent allergic asthma or allergic rhinitis who did not respond to an exercise challenge test. We selected 50 children, aged 9–16 years, with intermittent allergic bronchial asthma (Group 1) or allergic rhinitis without clinical manifestation of asthma for at least 12 months (Group 2). All patients performed the following tests in three different days (> 48 hours apart): Day 1: exhaled nitric oxide (FeNO) determination followed by baseline spirometry and reversibility to inhaled β2-agonists; Day 2: exercise challenge test followed by FeNO determination; Day 3: mannitol challenge test followed by FeNO determination. Forty children completed the study. Eighteen subjects of Group 1 (90%) and 5 subjects of Group 2 (25%) resulted positive to the mannitol test. Positive mannitol challenge subjects showed no statistically significant differences compared to negative subjects as regard baseline spirometry, reversibility to salbutamol and response to the exercise challenge test, but they had significantly higher FeNO values. In conclusion, the mannitol challenge test can be a diagnostic tool more useful than the exercise challenge test to identify BHR in a paediatric population with intermittent allergic asthma or allergic rhinitis because it is better reproducible, quick and easy to perform and well tolerated.

The role of inhaled corticosteroids in asthma exacerbation is debated. We compared high doses of nebulized budesonide versus high doses of nebulized flunisolide, in association with a short-acting beta-2-agonist, in the treatment of moderate asthma exacerbation in preschool children. In this randomized, parallel group, simple blind study, 46 children aged between 3 and 5 years affected by an acute moderate asthma attack were treated with nebulized flunisolide (Group 1) 40 μg/kg twice daily for 7 days and then 20 μg/kg twice daily for 14 days, or with nebulized budesonide (Group 2) 0.5 mg twice daily for 7 days then 0.25 mg twice daily for 15 days. Inhaled salbutamol (MDI+ spacer − 200 μg 4 times daily) was administered during the first 3 days of the study and then as needed. At TO, T7 and T21 days, airway resistances were evaluated with the forced oscillation technique before and after inhalation of inhaled salbutamol (200 mcg). Parents recorded symptoms and drug use on a diary card. Forty children completed the study. Airway resistances were significantly reduced at T7 (p< 0.01 flunisolide; p< 0.05 budesonide) and T21 (p< 0.05 flunisolide; p< 0.05 budesonide) versus T0 in both groups, although at T7 the reduction occurred faster in group 1 than in group 2 (p<0.01). During the first 7 days of treatment, symptom scores decreased in both groups; however, the decrease was greater in group 1 (p< 0.05). High doses of inhaled flunisolide and budesonide are both effective in the management of moderate asthma exacerbations in pre-school-age children, but the flunisolide therapeutic effect was faster than budesonide.
