• Of the 1,024 subjects (ndr: bambini), 663 (65%) were vitamin D sufficient, 260 (25%) were insufficient, and 101 (10%) were deficient
– Our current study found that children with asthma who are deficient in vitamin D levels have less improvement in prebronchodilator FEV1 over the course of 1 year when treated with inhaled corticosteroids as compared with children who are sufficient in vitamin D
• These findings support the hypothesis that vitamin D supplementation may enhance the antiinflammatory function of corticosteroids in patients with asthma

Is the Best Offense a Good D-fense?Should We Use Vitamin D as Adjunctive Therapy for Asthma?
The question of whether or not therapeutic use of vitamin D will be beneficial in asthma either as primary therapy or as adjunctive therapy to inhaled corticosteroids can only be answered with a prospective, blinded, randomized, placebo-controlled trial
As of July 2012, according to clinicaltrials.gov, a number of such trials are currently active nationally and internationally, though these appear to be primarily single-center studies of relatively small size given the prevalence of childhood asthma
Therefore, even after completion of these studies, there will likely be a need for a large, multicenter trial of vitamin D therapy in asthma with long-term follow-up similar to the CAMP study

• There are two conflicting hypotheses linking vitamin D to an increasing incidence of asthma and allergic diseases, according to the so-called "paradox of vitamin D"– Both an excess (resulting from supplementation) and a deficiency (due to low
solar exposure and the inability to compensate with diet) of vitamin D have been associated with an increased risk of asthma and allergies in Western countries
• Further studies are necessary to clarify the role of vitamin D in the induction of immune tolerance and the subsequent risk of developing allergic diseases

• In conclusion, evidence of the association among vitamin D and development of food allergy is rather scarce and conflicting
– Recent birth cohort studies showed no relationship between vitamin D deficiency and food allergy; the highest levels of vitamin D correlated with the higher risk of food allergy
– There is a lack of consistent data addressing the topic of vitamin D supplementation to prevent the development of food allergy
• Well designed trials on vitamin D supplementation are needed, particularly concerning food allergy, in order to give more strength and evidence to the hypothesis that vitamin D could really contribute to the prevention strategy

Antioxidant intake and allergic disease in children - 1
Elena Rosenlund et al, CEA 2012
• Background. Antioxidant intake may reduce the risk of allergic disease by protecting against oxidative tissue damage. Major sources of antioxidants in the Western world are fruits, vegetables (vitamin C, b-carotene, a-tocopherol), meat and milk (selenium, magnesium, zinc).
– Children may exclude or eat less of some fruits and vegetables due to crossreactivity between pollen and these foods, complicating assessment of causal relationships
• Objective. To investigate the association between dietary antioxidant intake and allergic disease, taking potential reverse causation into account
• Methods. Data on 2442 8-year-old children from the Swedish birth cohort study BAMSE were analysed
– Children with completed parental questionnaires on exposures and health, including a food-frequency questionnaire and who provided a blood sample were included
– Associations between antioxidant intake during the past year and current allergic disease were analysed using logistic regression

Antioxidant intake and allergic disease in children - 2
Elena Rosenlund et al, CEA 2012
• Results. An inverse association was observed between intake of b-carotene and rhinitis (ORadj, highest vs. lowest quartile, 0.67, 95% CI 0.49–0.93). Magnesium intake was inversely related to asthma (ORadj, 0.65, 95% CI 0.42–1.00) and atopic sensitisation (ORadj, 0.78, 95% CI 0.61–1.00)
• Following exclusion of children who avoided certain fruits, vegetables or milk due to allergic symptoms (n = 285), the inverse association remained between magnesium intake and asthma (ORadj, 0.58, 95% CI 0.35–0.98), whereas all other associations became non-significant
• Conclusion and clinical relevance. Diet modifications due to allergy may affect the antioxidant intake and needs to be considered when investigating the relationship between diet and allergic disease. Magnesium intake seems to have a protective effect on childhood asthma

• In this double blind clinical trial study we evaluated 60 patients with chronic stable asthma. The patients were divided into two groups (A and B) including 30 patients in each group
• In addition to standard asthma treatment (according to stepwise therapy in 4th step of bronchial asthma) in which the patients were controlled appropriately, group A received 1000 mg vitamin C daily and group B received placebo
• Comparing PFT (FEV1, FVC and FEV1/FVC) in group B during the study period showed a significant increase in FEV1 (P<0.05), while the other two parameters remained unchanged
• In group A, who received 1000 mg/day vitamin C, none of the spirometry parameters changed after one month treatment, indicating no effect of vitamin C treatment in the spirometry parameters

Correlation between serum 25-hydroxyvitamin D levels and severity of atopic dermatitis in children
Peroni D et al. British J Dermatol 2011;164, pp1078–1082
37 bb8m-12a
Grazie a Giuseppe Pingitore
Methods Using the SCORAD index, we evaluated the severity of disease in 37 children (17 girls and 20 boys) aged between 8 months and 12 years with AD, consecutively enrolled in the study. Serum levels of 25-hydroxyvitamin D [25(OH)D] were determined by a chemiluminescent method. Specific IgE (sIgE) to Staphylococcus aureus enterotoxins and sIgE to Malassezia furfur were assayed by the ImmunoCAP system. ANOVA and the Pearson correlation test were used for statistical evaluation.
Results We found severe, moderate and mild AD in nine (24%), 13 (35%) and 15 (41%) children, respectively. Mean ± SD serum levels of 25(OH)D were significantly higher (P < 0Æ05) in patients with mild disease (36Æ9 ± 15Æ7 ng mL ) compared with those with moderate (27Æ5 ± 8Æ3 ng mL or severe AD (20Æ5 ± 5Æ9 ng mL. The prevalence of patients with sIgE to microbial antigens increased in relation to vitamin D deficiency and AD severity.
Conclusions. These data suggest that vitamin D deficiency may be related to the severity of AD and advocate the need for studies evaluating the use of vitamin D as a potential treatment in patients with this disease.

Antioxidant intake and allergic disease in children - 1
Elena Rosenlund et al, CEA 2012
• Background. Antioxidant intake may reduce the risk of allergic disease by protecting against oxidative tissue damage. Major sources of antioxidants in the Western world are fruits, vegetables (vitamin C, b-carotene, a-tocopherol), meat and milk (selenium, magnesium, zinc).
– Children may exclude or eat less of some fruits and vegetables due to crossreactivity between pollen and these foods, complicating assessment of causal relationships
• Objective. To investigate the association between dietary antioxidant intake and allergic disease, taking potential reverse causation into account
• Methods. Data on 2442 8-year-old children from the Swedish birth cohort study BAMSE were analysed
– Children with completed parental questionnaires on exposures and health, including a food-frequency questionnaire and who provided a blood sample were included
– Associations between antioxidant intake during the past year and current allergic disease were analysed using logistic regression

Antioxidant intake and allergic disease in children - 2
Elena Rosenlund et al, CEA 2012
• Results. An inverse association was observed between intake of b-carotene and rhinitis (ORadj, highest vs. lowest quartile, 0.67, 95% CI 0.49–0.93). Magnesium intake was inversely related to asthma (ORadj, 0.65, 95% CI 0.42–1.00) and atopic sensitisation (ORadj, 0.78, 95% CI 0.61–1.00)
• Following exclusion of children who avoided certain fruits, vegetables or milk due to allergic symptoms (n = 285), the inverse association remained between magnesium intake and asthma (ORadj, 0.58, 95% CI 0.35–0.98), whereas all other associations became non-significant
• Conclusion and clinical relevance. Diet modifications due to allergy may affect the antioxidant intake and needs to be considered when investigating the relationship between diet and allergic disease. Magnesium intake seems to have a protective effect on childhood asthma

La Vit C Iraniana e l’ AsmaNadi et al, Act Med Iran 2012
• In this double blind clinical trial study we evaluated 60 patients with chronic stable asthma. The patients were divided into two groups (A and B) including 30 patients in each group
• In addition to standard asthma treatment (according to stepwise therapy in 4th step of bronchial asthma) in which the patients were controlled appropriately, group A received 1000 mg vitamin C daily and group B received placebo
• Comparing PFT (FEV1, FVC and FEV1/FVC) in group B during the study period showed a significant increase in FEV1 (P<0.05), while the other two parameters remained unchanged
• In group A, who received 1000 mg/day vitamin C, none of the spirometry parameters changed after one month treatment, indicating no effect of vitamin C treatment in the spirometry parameters
