SUMMARY OBJECTIVE: Children with cow’s milk allergy may be at nutritional risk due to the lower intake of nutrients, such as protein, calcium, and vitamin A, which are present in cow’s milk. The objective was to evaluate children’s diets with Children with cow’s milk allergy compared with healthy controls as well as to compare the intake of proteins and amino acids from the diet followed by Children with cow’s milk allergy who consume special infant formula or plant-based dairy alternatives with Children with cow’s milk allergy who do not consume special infant formula or plant-based dairy alternatives. METHODS: Through a cross-sectional controlled study, the dietary intake of 57 children (27 with immunoglobulin E-mediated Children with cow’s milk allergy and 30 healthy controls) was evaluated. Using 24-h nutritional recalls, the total energy intake value, macronutrients, and amino acids were calculated. RESULTS: No statistically significant difference was found between the Children with cow’s milk allergy group and healthy controls for the intake of proteins and amino acids. However, the Children with cow’s milk allergy do not consume special infant formula or plant-based dairy alternatives group had a lower protein (g/kg) and branched-chain amino acid (mg/kg) intake than the Children with cow’s milk allergy consume special infant formula or plant-based dairy alternatives group. CONCLUSIONS: The Children with cow’s milk allergy group achieved the recommendations for the intake of proteins and amino acids compared to the healthy control group. However, the Children with cow’s milk allergy do not consume special infant formula or plant-based dairy alternatives group had a lower intake of protein (g/kg) and branched-chain amino acid (mg/kg) than the Children with cow’s milk allergy consume special infant formula or plant-based dairy alternatives group.

Resumo Objetivo: Avaliar a espessura do complexo médio-intimal da carótida (CMIC) e os biomarcadores do metabolismo lipídico associados ao risco cardiovascular (RC) em pais de pacientes com ataxia-telangiectasia (AT) e verificar associação com gênero. Método: Estudo transversal prospectivo e controlado com 29 ATM heterozigotos e 14 controles saudáveis. Foram realizados exames bioquímicos e a espessura do CMIC por ultrassonografia. Resultados: A média da medida do CMIC nos ATM heterozigotos foi de 0,72± 0,1 mm (mínimo: 0,5 mm e máximo: 1,0 mm). Observou-se elevado percentual de valores acima do percentil 75 em relação ao referencial populacional (16 [76,2%]), sem diferença estatisticamente significante entre o gênero feminino e o masculino (11/15 [73,3%] vs. 5/6 [83,3%]; p=0.550). A comparação entre os ATM heterozigotos e os controles, estratificados por gênero, mostrou que, nos ATM heterozigotos, as mulheres tinham maiores concentrações de HDL-c em comparação aos homens, e valores mais elevados de PCR-us em relação às mulheres controle. Nos ATM heterozigotos, estratificando segundo gênero, a correlação entre HDL-c e PCR-us foi inversamente proporcional e mais forte entre as mulheres, com tendência à significância estatística. Conclusão: Os ATM heterozigotos não diferiram dos controles em relação aos biomarcadores estudados relacionados ao RC. Entretanto, a maioria deles apresentou aumento na espessura do CMIC, preditor independente de morte, risco para infarto do miocárdio e AVC, quando comparado ao referencial para a mesma faixa etária. Esse achado sugere RC nos ATM heterozigotos e aponta para a necessidade de monitoramento da espessura do CMIC e de orientações nutricionais.

Summary Objective: To evaluate the carotid intima-media complex (CIMC) thickness and lipid metabolism biomarkers associated with cardiovascular risk (CR) in parents of patients with ataxia-telangiectasia and verify an association with gender. Method: A cross-sectional and controlled study with 29 ATM heterozygotes and 14 healthy controls. Biochemical tests and CIMC thickness measurement were performed. Results: The mean CIMC measurement in heterozygous ATM was 0.72 ± 0.1 mm (minimum: 0.5 mm and maximum: 1.0 mm). Noticed high percentage of amounts above 75 percentile compared to the population referential (16 [76.2%]), without any significant statistical differences between the female and the male gender (11/15 [73.3%] vs. 5/6 [83.3%]; p=0.550). The comparison between heterozygous and controls, stratified by gender, showed that in heterozygous ATMs, women had higher concentrations of HDL-c compared to men, as well as higher values of hs-CRP in relation to the control women. In heterozygous ATMs, stratified by gender, the correlation between HDL-c and hs-CRP was inversely proportional and stronger among women, with a tendency to statistical significance. Conclusion: Heterozygous ATMs did not differ from controls in relation to the biomarkers studied related to CR. However, most of them presented increased CIMC, independent predictor of death, risk for myocardial infarction and stroke, compared to the referential for the same age group. This finding suggests CR in the heterozygous ATM and shows to the need to monitor CIMC thickness and nutritional orientations.
