Real-life data on the effectiveness of extensively hydrolyzed protein-based formula and amino acid-based formula in regaining weight and height in infants on a cow's milk protein elimination diet.

OBJECTIVE: To compare the effectiveness of extensively hydrolyzed protein-based formula (EHF) or amino acid-based formula (AAF) in reversing the weight and height deficit in infants on a cow's milk protein elimination diet. METHODS: Infants from a retrospective cohort who were fed EHF (n = 17) or AAF (n = 16) for at least 2 months on a cow's milk protein elimination diet were included. The weight and height values recorded in the infants' medical records were obtained. RESULTS: The mean age of the infants at the start of EHF and AAF were 5.8 ± 2.6 and 4.4 ± 2.5 months, respectively (P = 0.061). There was no difference between the groups in terms of the monthly weight gain (373.0 ± 212.2 and 453.1 ± 138.5 g, P = 0.223, respectively, for EHF and AAF), while the monthly increase in height was greater in the group fed with AAF (1.3 ± 0.5 and 1.8 ± 0.6, P = 0.030). A comparison between the difference in the initial z-score and in the oral challenge test of weight-for-age (+0.7 ± 1.2 and +1.3 ± 1.4, P = 0.262, respectively, for the EHF and AAF groups), height-for-age (+0.2 ± 1.1 and +1.2 ± 1.8, P = 0.090), and body mass index (BMI)-for-age (+0.7 ± 1.3 and +0.7 ± 1.5, P = 0.971) did not reveal a statistically significant difference between the groups. Correlation coefficients showed that the greater the initial nutritional deficit, the greater the positive variation between the beginning of each formula and the oral challenge test. CONCLUSION: EHF and AAF provided similar increases in the weight-for-age, height-for-age, and BMI-for-age z-scores in both groups. The monthly increase in height was greater in infants who received AAF.

Attitudes and practice of caregivers for cow's milk allergy according to stages of behavior change.

OBJECTIVE: To verify the attitudes and practices of dietary management for cow's milk allergy by caregivers according to the stages of behavior change. METHODS: Observational, cross-sectional study involving 30 caregivers of children with cow's milk allergy who were followed up in a specialized outpatient clinic, from July 2018 to May 2019. Data collection included a structured questionnaire about sociodemographic aspects, social classification and an adapted algorithm to classify the stages of behavior change based on a trans-theoretical model. RESULTS: Most caregivers (26/30) were females aged 20 to 48 years and belonging to social classes C, D and E. Regarding the stages of behavior change for the dietary management of cow's milk allergy according to the model, 80% of the participants (24/30) were in the action stage, while 20% (6/30) were in the maintenance stage. CONCLUSIONS: The attitudes and practices of caregivers for the dietary management of cow's milk allergy are influenced by feelings and emotions that can interfere with communication and the understanding of dietary guidelines; however, these caregivers are in different stages of action and maintenance to change behavior that correspond to their attitudes and practices.

Outcome of food intake and nutritional status after discontinuation of a cow’s-milk-free diet post negative oral food challenge in infants and children

Objective To evaluate the outcome of food intake and nutritional status post discontinuation of a cow’s-milk-free diet after a negative oral food challenge.Methods This was a prospective, uncontrolled study that evaluated food intake and nutritional status of a cohort of 80 infants and children under 5 years of age. Food intake and nutritional status were evaluated on the day of the oral food challenge test and after 30 days. Weight and height were measured on the day of the test and after 30 days.Results The mean age of the patients was 18.7 ± 12.4 months, and 58.7% were male. After discontinuation of the elimination diet, the children showed daily intake increases in (P < 0.001), protein (P < 0.001), carbohydrates (P = 0.042), calcium from foods (P < 0.001), calcium from foods and supplements (P < 0.001), phosphorus (P < 0.001), and vitamin D from foods (P = 0.006). The Z-scores (n = 76) on the day of the oral food challenge test and 30 days after restarting the consumption of cow’s milk were as follows: weight-for-age (P < 0.001) and height-for-age (P < 0.001), respectively.Conclusion Cow’s milk protein in the diet was associated with increased intake of energy, proteins, carbohydrates, calcium, phosphorus, and vitamin D, in addition to an increase in the Z-scores for weight-for-age and height-for-age (aU)

RESUMO Objetivo: Verificar as atitudes e práticas do manejo dietético da alergia ao leite de vaca por cuidadores segundo os estágios de mudança do comportamento. Métodos: Trata-se de estudo observacional e transversal que contou com 30 cuidadores de crianças com alergia ao leite de vaca, atendidas em ambulatório especializado, no período de julho de 2018 a maio de 2019. A coleta de dados contou com formulário estruturado que incluiu aspectos sociodemográficos, classificação social e algoritmo adaptado para classificar os estágios de mudança do comportamento de acordo com o modelo transteórico. Resultados: A maioria dos cuidadores (26/30) é do sexo feminino, com idade entre 20 e 48 anos e pertence às classes sociais C, D e E. Quanto aos estágios de mudança do comportamento em relação ao manejo dietético da alergia ao leite de vaca, segundo o modelo transteórico, é possível observar que 80% dos participantes (24/30) se encontram no estágio de ação, enquanto 20% (6/30) no estágio de manutenção. Conclusões: As atitudes e práticas de cuidadores de crianças sobre o manejo dietético na alergia ao leite de vaca são influenciadas por sentimentos e emoções que podem interferir na comunicação e no entendimento das orientações dietéticas. Esses cuidadores se encontram em estágios de ação e manutenção em relação à mudança de comportamento correspondentes às suas atitudes e práticas.

Knowledge and practice of pediatricians and nutritionists regarding treatment of cow's milk protein allergy in infants / Conhecimento e prática de pediatras e nutricionistas sobre o tratamento da alergia às proteínas do leite de vaca em lactentes

ABSTRACT Objective This study evaluated the knowledge and practices of pediatricians and nutritionists about cow's milk protein allergy in infants, with an emphasis on issues related to the exclusion diet and nutritional status. Methods A cross-sectional, descriptive study was performed with a convenience sample of 204 pediatricians and 202 nutritionists randomly invited in scientific events in the city of São Paulo, from November 2014 to March 2016. Results Between 1.5% and 21.0% of respondents indicated inadequate products for the treatment of cow's milk protein allergy, including goat's milk, beverages or juices based on soy extract, lactose-free milk formula and partially hydrolyzed formula. The daily calcium recommendation for children between zero and 36 months of age was correctly indicated by 27.0% of pediatricians and 46.0% of nutritionists (p=0.001). Additionally, 96.1% of pediatricians and 82.7% of dietitians (p<0.001) provided guidance on about labels of industrialized products. Conclusion Pediatricians and nutritionists present gaps in knowledge about cow's milk protein allergy treatment in infants and educational strategies that increase the knowledge of the professionals are important for the management of cow's milk protein allergy.
