    (Universidade Federal de São Paulo (UNIFESP), 2011-01-31) Ribeiro, Camila Cury [UNIFESP]; Morais, Mauro Batista de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Objective: To evaluate the knowledge and practice of pediatricians, gastroenterologists pediatricians, allergists and nutritionists regarding the primary prevention of food allergy. Methods: A descriptive cross-sectional study that enrolled pediatricians (n = 80), gastro-pediatricians (n = 120), allergists (n = 100) and nutritionists (n = 220), an amount of 520 professionals. The instrument collects used was a self-administered questionnaire prepared by the authors based on current recommendations of the major committees and societies related to prevention of food allergy. Results: The average age of professionals was 29.1 ± 5.8 years. The vast majority of the professionals was female, constituting a total 90.4% (n = 470) of respondents. The average time of graduation of professionals was 7.2 ± 5.8 years. Regarding the recommendation of exclusion diet on pregnancy, 89 (17.1%) professionals agreed with such practice, being the most indication by nutritionists. The gastro-pediatricians statistically differ from the others professionals by submitting the lowest rate of recommendation (p < 0.001). The recommendation of maternal exclusion diet on lactation was indicated by more number of professionals, constituting 40.8% (n = 212) of the sample, with the highest recommendation by nutritionists and pediatricians compared to pediatricians and allergists (p < 0.001). The duration of exclusive breastfeeding considered ideal was the period of 4 to 5.9 months indicated by 52.9% (n = 275) of professionals, according with the choices of most nutritionists, pediatricians and pediatricians. However, most allergists (65%; n = 65) indicated the range of 6 to 7.9 months. Regarding the time of introduction of complementary feeding, 218 (41.9%) professionals recommended modify the age of introduction to prevent the development of food allergy. The main period indicated was aged 6 to 7.9 months, indicated by 118 (54.1%) of respondents. Comparing the indication of the time of introduction of complementary feeding among professionals, 70 (70%) of allergists affirmed modify the time of introduction of complementary feeding (p < 0.001). The majority of special infant formulas indicated in case of impossibility of breastfeeding to prevent the development of food allergies were: Alfare® (70.6%), Neocate® (66.2%), Pregomin® (57.5%) and Nan HA® (42.1%). Conclusions: This study revealed there are misconceptions regarding the prevention of food allergy among all the categories of professionals. Our results confirm that the evaluation of knowledge and professional practice contributes to the definition of content that should be part of continuing education programs in the area of food allergy.

    Deficiência de vitamina D em crianças e adolescentes com alergia alimentar
    (Universidade Federal de São Paulo (UNIFESP), 2021) Pereira, Andressa Perez Dos Santos [UNIFESP]; Sarni, Roseli Oselka Saccardo [UNIFESP]; Universidade Federal de São Paulo
    Objective: To describe serum levels of vitamin D in children and adolescents with Food Allergy (FA) and to verify the association with the foods involved, time of sun exposure and nutritional status. Method: Through a cross-sectional study, 79 patients with FA, aged 2 to 15 years, attended at a referral clinical center, Brazil, were evaluated.Clinical data and blood samples were collected for analysis of 25(OH)D, calcium, phosphorus, alcaline phosphatase, parathyroid hormone and ultra-sensitive C- reactive protein. The cutoff point used for vitamin D deficiency was <20ng/mL. Multivariate linear regression analysis was performed to determine the impact of FA on serum vitamin D concentrations. Results: Vitamin D deficiency was detected in 45,6% of patients with a median age of 6.9 years (IQ 4,7;10,2), with approximately one-fourth pubertal and post-pubertal (p=0,037). The median of 25(OH)D serum levels was 21,1 ng/mL (IQ 17,8;26). FA to multiple foods (inverse) and time of sun exposure (direct) were independently associated with 25(OH)D serum levels (p=0,034 and p=0,014, respectively). The history of allergy to cow’s milk also pointed to lower levels [19,1ng/mL (IQ16,6; 24,4) vs 22,2 ng/mL (IQ18,1; 27,1) (p=0,056)]. Conclusions: Vitamin D deficiency reached about half of individuals with FA. Allergy to multiple foods and shorter sun exposure were associated with lower levels of vitamin D, reinforcing the importance of monitoring vitamin D status in patients with FA.
