ABSTRACT

Introducción. La prueba de provocación oral (PPO) para el diagnóstico de alergia a las proteínas de la leche de la vaca (APLV) presenta riesgos y requiere de recursos. Nuestro objetivo fue evaluar condiciones y pruebas complementarias para identificar una alta probabilidad de APLV. Población y métodos. Análisis secundario sobre estudio de pacientes atendidos en una unidad de alergia entre 2015 y 2018. Se determinaron las probabilidades prepruebas asociadas a los síntomas y sus combinaciones, y las probabilidades pospruebas luego de realizadas pruebas cutáneas y determinación de inmunoglobulina E (IgE) sérica. Resultados. Se evaluó la información de 239 pacientes. Se observaron probabilidades mayores al 95 % en pacientes con angioedema y combinación de urticaria y vómitos. Usando puntos de corte propuestos por Calvani et al., la combinación de vómitos con rinitis, sin angioedema, también superó el 95 %. Conclusión. Se ofrece una metodología para identificar pacientes en los que puede diagnosticarse APLV sin realización de PPO.


Introduction. The oral food challenge (OFC) for the diagnosis of cow's milk protein allergy (CMPA) poses risks and requires resources. Our objective was to assess conditions and complementary tests used to identify a high probability of CMPA. Population and methods. Secondary analysis of a study of patients seen at a unit of allergy between 2015 and 2018. Pre-testing probabilities associated with symptoms and their combinations and post-testing probabilities after skin prick testing and serum immunoglobulin E (IgE) levels were determined. Results. The data from 239 patients were assessed. A probability greater than 95% was observed for angioedema and a combination of urticaria and vomiting. Based on the cut-off points proposed by Calvani et al., the combination of vomiting with rhinitis, without angioedema, also exceeded 95%. Conclusion. A methodology is provided to identify patients in whom CMPA may be diagnosed without an OFC.

ABSTRACT

La leche humana es el estándar de oro para la nutrición del bebé y debe iniciarse en la primera hora de vida. La leche de vaca, de otros mamíferos o las bebidas vegetales no se deben ofrecer antes del año de vida. Sin embargo, algunos niños requieren, al menos en parte, de fórmulas infantiles. Aun con las sucesivas mejoras a lo largo de la historia mediante la incorporación de oliogosacáridos, probióticos, prebióticos, sinbióticos y postbióticos, las fórmulas infantiles siguen siendo perfectibles para reducir la brecha de salud entre los bebés amamantados y aquellos alimentados con fórmula. En este sentido, se espera que la complejidad de las fórmulas siga aumentando a medida que se conozca mejor cómo modular el desarrollo de la microbiota intestinal. El objetivo de este trabajo fue realizar una revisión no sistemática del efecto de los diferentes escenarios lácteos sobre la microbiota intestinal.


Human milk is the gold standard for infant nutrition, and breastfeeding should be started within the first hour of life. Cow's milk, other mammalian milk, or plant-based beverages should not be offered before 1 year of age. However, some infants require, at least in part, infant formulas. Even with subsequent enhancements throughout history, with the addition of oligosaccharides, probiotics, prebiotics, synbiotics, and postbiotics, infant formulas still have room for improvement in reducing the health gap between breastfed and formula-fed infants. In this regard, the complexity of infant formulas is expected to continue to increase as the knowledge of how to modulate the development of the gut microbiota is better understood. The objective of this study was to perform a non-systematic review of the effect of different milk scenarios on the gut microbiota.

ABSTRACT

O desenvolvimento e a ampliação do uso das vacinas durante décadas contribuíram para o controle e erradicação de doenças infecciosas, causando um grande impacto na saúde pública no mundo. A análise de segurança das vacinas percorre criteriosos processos e fases dos estudos clínicos, um dos pilares essenciais para aprovação regulatória e utilização do produto na população. O evento supostamente atribuído à vacinação e imunização (ESAVI), terminologia atual, é definido como qualquer ocorrência médica indesejada após a vacinação que possui, ou não, uma relação causal com o uso de uma vacina ou outro imunobiológico. Cabe ressaltar que eventos adversos mais raros ou inesperados, incluindo os eventos de hipersensibilidade, poderão ocorrer na fase pós-comercialização, quando as vacinas são aplicadas em milhões de pessoas. Neste artigo, serão discutidos os principais aspectos relacionados aos eventos adversos de hipersensibilidade pós-vacinais de interesse do especialista, e os desafios frente ao reconhecimento do agente causal e conduta a ser adotada. Além disso, serão revisados os potenciais alérgenos presentes nas vacinas de uso rotineiro para auxiliar o profissional de saúde na identificação de pacientes com potencial de risco de ESAVI por tais componentes. A atualização do conhecimento acerca da segurança e dos benefícios das vacinas pelos profissionais de saúde, sobretudo em populações especiais, contribui para condutas em imunização mais apropriadas, reduzindo o risco de exposição a um possível alérgeno em pessoas comprovadamente alérgicas às vacinas ou a alguns dos seus componentes, além de evitar contraindicações desnecessárias em eventos coincidentes ou não graves.


The expansion of vaccine use and development in recent decades has contributed to the control and eradication of infectious diseases, causing a major impact on public health worldwide. Vaccine safety analysis, which involves careful processes and clinical study, is one of the essential pillars of regulatory approval and use in the population. In current terminology, events supposedly attributable to vaccination and immunization (ESAVI) are defined as any unwanted medical occurrence after vaccination that may or may not have a causal relationship with vaccines or other immunobiologicals. It is noteworthy that rare or unexpected adverse events, including hypersensitivity, can occur during the post-marketing phase, when vaccines are administered to millions of people. In this article, we will discuss the main aspects of post-vaccine hypersensitivity events of interest to specialists and challenges to recognizing the causal agent and appropriate clinical practice. Potential allergens in routine vaccines will also be reviewed to help health professionals identify patients with a potential risk of ESAVI due to such components. Updating health professionals' knowledge about the safety and benefits of vaccines, particularly in special populations, can contribute to more appropriate clinical practice regarding immunization, reducing the risk of exposure to possible allergens in people with allergies to vaccines or their components, avoiding unnecessary contraindications in coincidental or non-serious events.

ABSTRACT

Objective: To investigate the natural history and risk factors for continued allergy in infants with IgE-mediated cow's milk protein allergy (CMPA). Methods: This was a prospective cohort study that included 72 infants under 24 months of age diagnosed with IgE-mediated CMPA in the allergy clinic of the Children's Hospital, Capital Institute of Pediatrics from October 2019 to November 2020. General information, clinical manifestations, serum total IgE, cow's milk specific IgE, and cow's milk protein component specific IgE were collected. Follow-ups were conducted at 24 and 36 months of age, and the patients were divided into the persistent allergy group and the tolerance group based on whether they developed cow's milk tolerance at 36 months of age. Mann-Whitney U test, chi-square test, and binary Logistic regression were used for intergroup comparison and multivariate analysis. Results: Among the 72 CMPA children, there were 42 boys and 30 girls, with an age of 10 (7, 15) months at enrollment. Cow's milk protein tolerance was observed in 32 cases (44%) and 46 cases (64%) at 24 and 36 months of age, respectively. There were 26 cases in the persistent allergy group and 46 cases in the tolerance group. The proportion of respiratory symptoms, history of wheezing, positive specific IgE for α-lactalbumin and the total IgE level in the persistent allergy group were higher than that in the tolerance group (7 cases (27%) vs. 0, 6 cases (23%) vs. 2 cases (4%), 67% (14/21) vs. 26% (10/39), 225 (151, 616) vs. 48 (21, 185) kU/L, χ2=10.82, 4.16, 9.57, Z=4.07, all P<0.05). Multivariate Logistic regression analysis showed that anaphylaxis (OR=21.14, 95%CI 2.55-175.14, P=0.005), a history of allergic rhinitis (OR=5.94, 95%CI 1.54-22.86, P=0.005), elevated milk specific IgE (OR=1.04, 95%CI 1.01-1.08, P=0.024), and positive casein specific IgE (OR=6.64, 95%CI 1.39-31.69, P=0.018) were risk factors for continuous CMPA. Conclusions: Most infants with IgE-mediated CMPA can achieve tolerance within 3 years. Anaphylaxis, a history of allergic rhinitis, elevated milk specific IgE levels, and casein sensitization are risk factors for continuous allergy.

ABSTRACT

El parto prematuro, la cesárea, el uso de antibióticos y la lactancia materna limitada son señalados como responsables en parte del aumento de enfermedades crónicas no transmisibles en niños, como las alergias, principalmente la alergia a la proteína de la leche de vaca (APLV). Quienes desarrollan enfermedades alérgicas muestran diferencias en la composición de su microbiota intestinal durante los primeros meses de vida, en comparación con los que no lo hacen. Las intervenciones tempranas para modular la microbiota intestinal y el sistema inmunológico pueden ser herramientas claves para el abordaje y tratamiento de la APLV. El criterio clínico y el trabajo interdisciplinario de alergólogos, gastroenterólogos, inmunólogos, microbiólogos y nutricionistas le permitirá al pediatra lograr un adecuado diagnóstico y un tratamiento oportuno. En este contexto, el empleo de bióticos (prebióticos, probióticos, sinbióticos y posbióticos) como herramientas nutricionales complementarias tiene un presente con sustento científico y un futuro promisorio para la prevención y tratamiento de estas patologías.


Preterm birth, C-section, antibiotic use, and limited breastfeeding are blamed in part for the increasing incidence of chronic noncommunicable diseases among children, such as allergies, mainly cow's milk protein allergy (CMPA). Those who develop allergic diseases, against those who do not, show differences in the composition of their gut microbiota during the first months of life. Early interventions to modulate the intestinal microbiota and the immune system may be the key tools for the management of CMPA. Clinical judgment and the interdisciplinary work of allergists, gastroenterologists, immunologists, microbiologists, and nutritionists will allow pediatricians to achieve an adequate diagnosis and a timely treatment. In this setting, the use of biotics (prebiotics, probiotics, synbiotics, and postbiotics) as supplementary dietary tools is scientifically supported at present and seems to be very promising for the prevention and treatment of these conditions.

ABSTRACT

A urticária aguda é uma causa frequente de consulta com alergistas, caracterizada por urticas e/ou angioedema. Embora autolimitada e benigna, pode causar desconforto significativo e raramente representar uma doença sistêmica grave ou reação alérgica com risco de vida. Nesta revisão, elaborada pelo Departamento Científico de Urticária da Associação Brasileira de Alergia e Imunologia, foram abordadas as principais questões referentes ao tema para auxiliar o médico especialista e generalista.


Acute urticaria is a frequent cause of consultations with allergists, being characterized by wheals and/or angioedema. Although self-limited and benign, it may cause significant discomfort and uncommonly represent a serious systemic disease or life-threatening allergic reaction. In this review prepared by the Urticaria Scientific Department of the Brazilian Association of Allergy and Immunology, the main questions about this topic are addressed to help specialists and general practitioners.

ABSTRACT

Nas últimas décadas observa-se aumento na prevalência mundial de alergia alimentar, que já acomete aproximadamente 6% das crianças, atribuído à interação entre fatores genéticos, ambientais e alterações na resposta imunológica e pode envolver reações mediadas por IgE, não mediadas e mistas. As formas não IgE mediadas decorrem de reação de hipersensibilidade tardia, mediada por linfócitos T e afetam prioritariamente o trato gastrointestinal, como a Síndrome da enterocolite induzida por proteína alimentar (FPIES), Síndrome da proctocolite alérgica induzida por proteína alimentar (FPIAP), Síndrome da enteropatia induzida por proteína alimentar (FPE) e doença celíaca. As características destas reações podem ser diferenciadas por sua apresentação clínica, gravidade, idade de início e história natural. Entre as reações alérgicas aos alimentos não IgE mediadas, a proctocolite alérgica é a mais frequente. Geralmente ocorre no primeiro ano de vida e apresenta excelente prognóstico. Embora costume ter um curso benigno, traz grande preocupação aos cuidadores por frequentemente cursar com quadro de hematoquezia exigindo diagnóstico diferencial adequado. O conhecimento e manejo da proctocolite alérgica é de suma importância para a prática médica em Alergia e Imunologia. Seu diagnóstico é baseado na história clínica seguindo-se dieta de exclusão, especialmente do leite de vaca, com subsequente provocação oral, que geralmente pode ser realizada no domicílio. O diagnóstico preciso é importante, para se evitar dietas de exclusão desnecessárias. Nesta revisão foram utilizados artigos publicados nos últimos anos, com busca realizada através da base PubMed envolvendo revisões, diagnóstico e tratamento de alergias não IgE mediadas, com foco em proctocolite alérgica.


An increase in the worldwide prevalence of food allergies has been observed in the past decades, currently affecting 6% of children. This increase has been associated with the interaction between genetic, environmental, and immune response factors and can be observed in IgE, non-IgE, and mixed mediated reactions. Non-IgE mediated food allergies result from delayed-type hypersensitivity and mostly affect the gastrointestinal tract, such as food protein-induced enterocolitis syndrome (FPIES), food protein-induced allergic proctocolitis (FPIAP), food protein-induced enteropathy (FPE), and celiac disease. These reactions can be differentiated by their clinical presentation, severity, age at onset, and natural history. Among non-IgE-mediated allergic reactions to food, allergic proctocolitis is the most frequent. It usually develops in the first year of life and has excellent prognosis. Although it has a benign course, allergic proctocolitis is challenging for health care professionals because it often presents with hematochezia, requiring an accurate differential diagnosis. Knowledge and management of allergic proctocolitis is of paramount importance for medical practice in allergy and immunology. Its diagnosis is based on clinical history followed by elimination diet, especially cow's milk, with subsequent oral food challenge, which may usually be performed at home. Accurate diagnosis is important to avoid unnecessary elimination diets. For this review, PubMed database was searched for recently published literature reviews and studies on the diagnosis and treatment of non- IgE mediated allergies, with a focus on allergic proctocolitis.

ABSTRACT

En las últimas décadas, se ha observado una mayor prevalencia, persistencia y gravedad de la alergia a la proteína de leche de vaca (APLV). Se han postulado diversas hipótesis respecto a posibles mecanismos responsables, con énfasis en el papel de la microbiota en la inducción y el mantenimiento de la tolerancia inmunitaria, así como la importancia del establecimiento temprano de una microbiota saludable a través de la promoción de la lactancia materna, el parto por vía vaginal, el uso racional de antibióticos e inhibidores de la bomba de protones, junto con la introducción temprana y variada de alimentos. La utilización de probióticos y la inmunoterapia específica para alérgenos (ITA) emergen como las estrategias terapéuticas con más evidencia a favor para la adquisición de tolerancia. El objetivo de esta revisión ha sido describir la información actual respecto a los mecanismos inmunitarios involucrados en la APLV, el papel de la microbiota y las perspectivas futuras en el tratamiento.


In recent decades, a higher prevalence, persistence, and severity of cow's milk protein allergy (CMPA) have been observed. Different hypotheses have been proposed in relation to potential responsible mechanisms, with emphasis on the role of the microbiota in the induction and maintenance of immune tolerance as well as the importance of establishing a healthy microbiota in an early manner through the promotion of breastfeeding, vaginal delivery, rational use of antibiotics and proton pump inhibitors, along with an early introduction of varied foods. The use of probiotics and allergenspecific immunotherapy (AIT) come up as the treatment strategies with the greatest evidence in favor of tolerance acquisition. The objective of this review was to describe the information currently available about the immune mechanisms involved in CMPA, the role of microbiota, and future treatment perspectives.

ABSTRACT

Objetivos: Descrever uma população de crianças com alergia à proteína do leite de vaca (APLV) IgE mediada, submetidas ao teste de provocação oral (TPO) com alimentos processados vs. in natura, e comparar características clínico-epidemiológicas e laboratoriais, avaliando preditores de desfecho ao uso dessas diferentes apresentações de proteína. Métodos: Estudo transversal realizado em ambulatório de alergia de um hospital terciário em Fortaleza, Ceará. A coleta dos dados foi realizada entre outubro de 2018 a setembro de 2019. O questionário foi preenchido com os dados epidemiológicos, clínicos e laboratoriais encontrados no prontuário; amostra total de 49 crianças, com APLV IgE mediada tolerantes ao TPO com alimentos processados ou in natura. Resultados: Na comparação das características clinico-epidemiológicas das populações tolerantes a alimentos in natura vs. processados (respectivamente), a maioria apresentou dados semelhantes, como sexo masculino (60% vs. 57,9%), etnia parda (73,3% vs. 68,4%), idade gestacional a termo (80% vs. 77,8%), sem intercorrências durante a gestação (58,3% vs. 80,0%) ou parto (70% vs. 78,9), média de idade materna (32 anos vs. 35 anos), escolaridade materna (ensino médio completo - 43,3% vs. 47,4%), idade de início dos sintomas de APLV entre 1 e 6 meses (76,7% vs. 68,4%), aleitamento materno exclusivo entre 4 e 6 meses (60% vs. 68,45%), histórico de alergia familiar alimentar (73% vs. 68,4%), sendo as principais comorbidades alérgicas as respiratórias (38,9% vs. 35,7%) e alimentares (38,9% vs. 35,7%). Em relação aos dados laboratoriais, a maioria das frações de proteína no grupo tolerante a alimentos in natura e a alimentos processados apresentou valores ≤ 10 kU/L. Foi constatado que a idade materna (p = 0,006) e a idade de introdução de fórmula complementar (p = 0.020) se correlacionam de forma estatisticamente significante no grupo de pacientes tolerantes a alimentos processados. Conclusões: Foi observado que a idade materna (p = 0,006) e a idade de introdução de fórmula complementar (p=0.020) se correlacionam de forma estatisticamente significante no grupo de pacientes tolerantes alimentos processados. Os dados laboratoriais seguiram distribuição proporcionais entre os dois grupos, com maior frequência de valores ≤ 10 kU/L para todas as frações de proteína do leite de vaca, sem significância estatística. Estudos populacionais semelhantes em populações APLV IgE mediada são importantes para caracterizar melhor esse fenótipo e otimizar ferramentas diagnósticas e protocolos de tratamento. Destaca-se também o papel da terapia baked, que auxilia na aquisição de tolerância a diferentes apresentações da PLV de forma mais breve, melhorando, portanto, a qualidade de vida desses pacientes (AU)


Objectives: To describe the population of children with IgE-mediated CMPA tolerant to processed or raw CMP in the OFC, comparing their clinical, epidemiological and laboratory characteristics and evaluating the possible predictors of outcomes associated with these different presentations of CMP. Methods: Cross-sectional study carried out in an allergy clinic of a tertiary hospital in Fortaleza, Ceará. Data collection was carried out between October 2018 and September 2019. The questionnaire was filled out with epidemiological, clinical and laboratory data found in the medical records. The total sample was composed of 49 children with IgE-mediated CMPA tolerant to processed or raw foods in the OFC. Results: The comparison of the clinical and epidemiological characteristics of populations tolerant to raw foods vs. processed (respectively) showed similarities, such as the predominance of the male gender (60% vs. 57.9%); mixed ethnicity (73.3% vs. 68.4%); delivery at term (80% vs. 77 .8%); no complications during pregnancy (58.3% vs. 80.0%) or childbirth (70% vs. 78.9); mean maternal age (32 years vs. 35 years); level of education of the mothers (complete high school - 43.3% vs. 47.4%); age of onset of CMPA symptoms between 1 and 6 months (76.7% vs. 68.4%); exclusive breastfeeding for 4 to 6 months (60% vs. 68.45%); family history of food allergy (73% vs. 68.4%); and respiratory (38.9% vs. 35.7%) and food allergies (38.9% vs. 35.7%) as the main allergic comorbidities. Regarding laboratory data, most protein fractions had values ≤ 10 kU/L in both groups. It was found that maternal age (p = 0.006) and age of introduction of formula (p = 0.020) were statistically significant in the group of patients tolerant to processed foods. Conclusions: It was observed that maternal age (p = 0.006) and age of introduction of formula (p = 0.020) were statistically significant in the group of patients tolerant to processed foods. Laboratory data were proportionally distributed across the two groups, with a higher frequency of values lower than or equal to 10 kU/L for all CMP fractions, with no statistical significance between the groups. Similar population studies in IgE-mediated CMPA populations are important to better characterize this phenotype and optimize diagnostic tools and treatment protocols. The role of baked therapy is also noteworthy, as it helps patients to develop tolerance to different presentations of CMP more quickly, improving their quality of life (AU)

ABSTRACT

Introducción. La alergia a las proteínas de la leche de vaca es la alergia alimentaria más frecuente en los niños y para su diagnóstico se emplean historia clínica dirigida y prueba de provocación oral (PPO), el dosaje sérico de inmunoglobulina E específica (sIgE) y pruebas cutáneas de puntura (SPT, por su sigla en inglés). Sin embargo, su utilidad diagnóstica es difícil de establecer en la población local. El objetivo fue evaluar la utilidad de las pruebas para el diagnóstico de alergia a las proteínas de la leche de vaca (PLV) en la población estudiada. Población y métodos. Análisis retrospectivo de datos de pacientes atendidos en la Unidad de Alergia del Hospital Elizalde entre 2015 y 2018. Se evaluaron SPT y sIgE para leche, alfa-lactoalbúmina, beta-lactoglobulina y caseína, seguidos de PPO y se determinó la utilidad diagnóstica para cada prueba, y sus combinaciones. Resultados. Se evaluaron las pruebas de 239 pacientes. La PPO fue hospitalaria en el 54,8 % de los casos, por reexposición domiciliara en el 35,5 % y en el 9,6 % por incorporación de PLV a la madre. La mayor especificidad fue la de SPT con caseína (96,7 %; intervalo de confianza [IC95%]: 90,8-99,3) y la mayor sensibilidad, la de la combinación de SPT y sIgE con los 4 alérgenos (55,3 %; IC95%: 45,7-64,6). Conclusiones. El trabajo estableció la utilidad diagnóstica de las SPT y el sIgE en la población estudiada.


Introduction. Cow's milk protein allergy is the most common food allergy among children. It can be diagnosed based on a guided history taking and using an oral food challenge (OFC), serum specific immunoglobulin E levels (sIgE), and skin prick tests (SPT). However, it is difficult to establish their diagnostic performance in the local population. Our objective was to assess the usefulness of tests used to diagnose cow's milk protein (CMP) allergy in the studied population. Population and methods. Retrospective analysis of data from patients seen at the Unit of Allergy of a tertiary care pediatric hospital between 2015 and 2018. SPT and sIgE tests were done for milk, alpha-lactalbumin, beta-lactoglobulin, and casein, followed by an OFC, and the diagnostic usefulness of each test, as well as their combination, was established. Results. The tests of 239 patients were assessed. OFC was performed at the hospital in 54.8 % of cases, via a rechallenge test at home in 35.5 %, and through CMP intake by the mother in 9.6 %. The highest specificity was observed with the casein SPT (96.7 %; 95 % confidence interval [CI]: 90.8-99.3) and the highest sensitivity, with the 4-allergen SPT and sIgE combination (55.3 %; 95 % CI: 45.7-64.6). Conclusions. The study established the diagnostic usefulness of SPT and sIgE in the studied population.

ABSTRACT

El parto prematuro, las cesáreas, los antibióticos y la lactancia materna limitada contribuyen al aumento de enfermedades crónicas no transmisibles. El objetivo fue realizar una revisión descriptiva del uso de probióticos en pediatría, con foco en la cepa Lactobacillus rhamnosus GG. Ciertos probióticos han demostrado ser eficaces en la diarrea aguda y en la diarrea asociada a antibióticos. L. rhamnosus GG y Saccharomyces boulardii pueden acortar la duración y los síntomas. L. reuteri DSM 17938 y L. rhamnosus GG fueron efectivos para el abordaje del cólico del lactante. El uso de esta cepa en fórmulas infantiles para alergia a las proteínas de leche de vaca promovería la adquisición más temprana de tolerancia. En la prevención de dermatitis atópica, la administración de L. rhamnosus GG durante el embarazo redujo su manifestación en el bebé. El empleo de probióticos como coadyuvantes es una posibilidad para considerar en la práctica pediátrica actual.


Preterm birth, C-sections, antibiotics, and limited breastfeeding contribute to the increase in noncommunicable diseases. Our objective was to perform a descriptive review of probiotic use in pediatrics, focused on Lactobacillus rhamnosus GG. Certain probiotics have demonstrated to be effective in acute diarrhea and antibiotic-associated diarrhea. L. rhamnosus GG and Saccharomyces boulardii may shorten their duration and symptoms. L. reuteri DSM 17938 and L. rhamnosus GG were effective to manage infant colic. The use of this strain in infant formulas for cow's milk protein allergy may promote an earlier tolerance acquisition. In relation to the prevention of atopic dermatitis, the administration of L. rhamnosus GG during pregnancy reduced its development in the infant. The use of probiotics as adjuvants is a possibility to consider in current pediatric practice.

Resultados: Na comparação das características clinico-epidemiológicas das populações tolerantes a alimentos in natura vs. processados (respectivamente), a maioria apresentou dados semelhantes, como sexo masculino (60% vs. 57,9%), etnia parda (73,3% vs. 68,4%), idade gestacional a termo (80% vs. 77,8%), sem intercorrências durante a gestação (58,3% vs. 80,0%) ou parto (70% vs. 78,9), média de idade materna (32 anos vs. 35 anos), escolaridade materna (ensino médio completo - 43,3% vs. 47,4%), idade de início dos sintomas de APLV entre 1 e 6 meses (76,7% vs. 68,4%), aleitamento materno exclusivo entre 4 e 6 meses (60% vs. 68,45%), histórico de alergia familiar alimentar (73% vs. 68,4%), sendo as principais comorbidades alérgicas as respiratórias (38,9% vs. 35,7%) e alimentares (38,9% vs. 35,7%). Em relação aos dados laboratoriais, a maioria das frações de proteína no grupo tolerante a alimentos in natura e a alimentos processados apresentou valores ≤ 10 kU/L. Foi constatado que a idade materna (p = 0,006) e a idade de introdução de fórmula complementar (p = 0.020) se correlacionam de forma estatisticamente significante no grupo de pacientes tolerantes a alimentos processados. Conclusões: Foi observado que a idade materna (p = 0,006) e a idade de introdução de fórmula complementar (p=0.020) se correlacionam de forma estatisticamente significante no grupo de pacientes tolerantes alimentos processados. Os dados laboratoriais seguiram distribuição proporcionais entre os dois grupos, com maior frequência de valores ≤ 10 kU/L para todas as frações de proteína do leite de vaca, sem significância estatística. Estudos populacionais semelhantes em populações APLV IgE mediada são importantes para caracterizar melhor esse fenótipo e otimizar ferramentas diagnósticas e protocolos de tratamento. Destaca-se também o papel da terapia baked, que auxilia na aquisição de tolerância a diferentes apresentações da PLV de forma mais breve, melhorando, portanto, a qualidade de vida desses pacientes.

ABSTRACS: Objectives: To describe the population of children with IgE-mediated CMPA tolerant to processed or raw CMP in the OFC, comparing their clinical, epidemiological and laboratory characteristics and evaluating the possible predictors of outcomes associated with these different presentations of CMP. Methods: Cross-sectional study carried out in an allergy clinic of a tertiary hospital in Fortaleza, Ceará. Data collection was carried out between October 2018 and September 2019. The questionnaire was filled out with epidemiological, clinical and laboratory data found in the medical records. The total sample was composed of 49 children with IgE-mediated CMPA tolerant to processed or raw foods in the OFC. Results: The comparison of the clinical and epidemiological characteristics of populations tolerant to raw foods vs. processed (respectively) showed similarities, such as the predominance of the male gender (60% vs. 57.9%); mixed ethnicity (73.3% vs. 68.4%); delivery at term (80% vs. 77 .8%); no complications during pregnancy (58.3% vs. 80.0%) or childbirth (70% vs. 78.9); mean maternal age (32 years vs. 35 years); level of education of the mothers (complete high school - 43.3% vs. 47.4%); age of onset of CMPA symptoms between 1 and 6 months (76.7% vs. 68.4%); exclusive breastfeeding for 4 to 6 months (60% vs. 68.45%); family history of food allergy (73% vs. 68.4%); and respiratory (38.9% vs. 35.7%) and food allergies (38.9% vs. 35.7%) as the main allergic comorbidities. Regarding laboratory data, most protein fractions had values ≤ 10 kU/L in both groups. It was found that maternal age (p = 0.006) and age of introduction of formula (p = 0.020) were statistically significant in the group of patients tolerant to processed foods. Conclusions: It was observed that maternal age (p = 0.006) and age of introduction of formula (p = 0.020) were statistically significant in the group of patients tolerant to processed foods. Laboratory data were proportionally distributed across the two groups, with a higher frequency of values lower than or equal to 10 kU/L for all CMP fractions, with no statistical significance between the groups. Similar population studies in IgE-mediated CMPA populations are important to better characterize this phenotype and optimize diagnostic tools and treatment protocols. The role of baked therapy is also noteworthy, as it helps patients to develop tolerance to different presentations of CMP more quickly, improving their quality of life. (AU)

ABSTRACT

Objective: To analyze the clinical features of IgE-mediated cow's milk protein allergy (CMPA) in children aged 0-5 years. Methods: This cross-sectional study collected the data on children diagnosed with CMPA in the Department of Allergy at the Children's Hospital of the Capital Institute of Pediatrics from October 2019 to November 2020 and improved peripheral blood routine,total IgE defection, milk specific IgE (sIgE) defection,SPT and milk component defection,diagnosis of severe anaphylaxis based on clinical manifestations. Rank-sum test and chi-square test are used for statistical analysis of clinical characteristics between groups. Results: A total of 106 children (67 boys and 39 girls) were enrolled with the age of 15 (8, 34) months, including 42 cases (≤ 1 year of age), 39 cases (>1-<3 years of age) and 25 cases(≥3 years of age), the onset age of 6 (5, 8) months. Among them, 95 cases (89.6%) were reacted after consuming milk or its products, 42 cases (39.6%) had reaction due to skin contact and 11 cases (10.4%) reacted after exclusive breastfeeding. The onset time of milk product consumption was 45 (1, 120) min, skin contact pathway was 10 (5, 30) min and symptoms in breastfeeding pathway was 121 (61, 180) min. There was statistical difference among the time of symptoms (χ2=77.01, P<0.001).The cutaneous reaction was most common (100 cases, 94.3%), followed by digestive (20 cases, 18.9%) and respiratory (16 cases, 15.1%), and the nervous symptoms (1 case, 0.9%) were uncommon and 24 cases (22.6%) had at least one episode of anaphylaxis. There were 87 cases (82.1%) also diagnosed with other food allergies, 94 cases (88.7%) with previous eczema, 57 cases (53.8%) with history of rhinitis, and 23 cases (21.7%) with history of wheezing. The total IgE level was 191.01 (64.71, 506.80) kU/L, and the cow's milk sIgE level was 3.03 (1.11, 15.24) kU/L. The maximum diameter of the wheal in SPT was 8.2 (4.0, 12.0) mm. Component resolved diagnosis showed that 77 cases (81.9%) were sensitized to at least one out of 4 main components, including casein, α lactalbumin, β lactoglobulin and bovine serum albumin.The possibility of anaphylaxis in children with milk sIgE grade Ⅳ-Ⅵ was higher than that in children with grade 0-Ⅲ (57.7% (15/26) vs. 12.5% (10/80), OR=9.545, 95%CI 3.435-26.523). Children with milk SPT ≥+++ had a higher probability of anaphylaxis than those with milk SPT ≤++ (34.4% (11/32) vs. 11.5% (3/26), OR=4.016, 95%CI 0.983-16.400). Anaphylaxis were more common in α lactalbumin positive children than in negative children (34.3% (13/38) vs. 14.2% (8/56), χ2=1.23,P=0.042). Conclusions: CMPA in children has early onset and diversified clinical manifestations, which are mainly cutaneous symptoms. Most children are sensitized to at least one allergen component. Serum sIgE level, SPT reaction and allergen components play important roles in the diagnosis and evaluation of CMPA, and higher milk sIgE level may predict a higher risk of anaphylaxis.

ABSTRACT

ABSTRACT Objective To assess linear growth and weight gain in infants with suspected cow's milk protein allergy with gastrointestinal manifestations, seen at a gastropediatrics clinic. Methods A retrospective cohort study conducted with demographic, clinical, anthropometric and dietary information on 84 infants first seen between 2015 and 2018 and followed-up for six months. Stature-for-age, weight-for-age, and body mass index-for-age in z-scores were evaluated according to the cut off points established by the World Health Organization in 2006. Accelerated growth or catch-up was considered a gain ?0.67 in the z-score of the referred indices, evaluated at 3 and 6 months. Results Median age at baseline was 4.0 months and 88.1% of the infants were already in diet exclusion. Regarding the anthropometric evaluation short stature frequency was 15.5% and the underweight frequency was 8.3% and 3.6% respectively based on the weight-for-age and body mass index-for-age indices. High recovery growth was observed during the follow-up period but was not considered catch up. In boys, the gains in weight-for-age and body mass index-for-age were significant (p=0.02 and p=0.01 respectively) and close to the threshold that characterizes the catch up, 0.58 and 0.59, respectively. In girls, significant gains in stature-for-age and weight-for-age (0.38 and 0.37 respectively, p=0.02 for both) were observed. Conclusion Infants with suspected cow's milk protein allergy with gastrointestinal manifestations should have early access to specialized nutritional counseling to avoid exposure to allergenic food and control allergy symptoms, thereby avoiding malnutrition and ensuring adequate nutritional recovery.


RESUMO Objetivo Avaliar o crescimento linear e o ganho de peso de lactentes com suspeita de alergia à proteína do leite de vaca, com manifestações gastrointestinais, atendidos em um ambulatório de gastropediatria. Métodos Estudo de coorte retrospectivo, com informações demográficas, clínicas, antropométricas e dietéticas de 84 lactentes que iniciaram atendimento entre 2015 e 2018 e foram acompanhados durante seis meses. Foram avaliados os índices estatura/idade, peso/idade e índice de massa corporal/idade em escore-z, segundo os pontos de corte da Organização Mundial de Saúde de 2006. Considerou-se crescimento acelerado (ou catch-up growth) um ganho ?0,67 escore-z nos referidos índices, avaliados em três e seis meses. Resultados No baseline, a mediana de idade foi 4,0 meses e 88,1% dos lactentes já estavam em dieta de exclusão. A frequência de baixa estatura foi de 15,5% e a de baixo peso foi de 8,3% e de 3,6% segundo os índices peso/idade e índice de massa corporal/idade, respectivamente. Houve elevado crescimento de recuperação durante o período de acompanhamento, mas que não configurou catch up. Nos meninos, ganhos no peso/idade e índice de massa corporal/idade foram significantes (p=0,02 e p=0,01) e próximos do limiar que caracteriza catch up: 0,58 e 0,59, respectivamente. Nas meninas, foram observados ganhos significantes na estatura/idade e peso/idade, de 0,38 e 0,37 (p=0,02 para ambos). Conclusão Demonstrou-se que lactentes com suspeita de alergia à proteína do leite de vaca, com manifestações gastrointestinais, deveriam ter acesso precoce ao aconselhamento nutricional para evitar exposição ao alimento alergênico, controlar sintomas e, assim, evitar a desnutrição ou garantir recuperação nutricional adequada.

ABSTRACT

La leche humana es el alimento ideal para los lactantes y sus beneficios se manifiestan en el corto y el largo plazo. En situaciones de crisis es cuando más se debe enfatizar en la lactancia materna, considerada una de las intervenciones más costo-efectivas para reducir la morbimortalidad infantil. Más allá de las múltiples ventajas que la leche humana tiene en relación con el vínculo madre-hijo y las capacidades biológicas e inmunológicas, lo más importante es que la leche materna cubre todas las necesidades nutricionales. Cuando la lactancia materna no es posible, la Organización Mundial de la Salud recomienda, como primera opción, las fórmulas infantiles. La segunda opción es leche de vaca (LV) diluida, que conlleva riesgos de deficiencias nutricionales en el lactante que deben ser monitoreadas en forma estrecha y oportunamente subsanadas. Los principales riesgos de deficiencias en el lactante que recibe LV diluida son las de hierro, cinc, vitaminas A, D, C y E, aminoácidos y ácidos grasos esenciales


Breast milk is the ideal food for infants and its benefits can be observed in the short and long term. In crisis situations, breastfeeding should be promoted the most because it is one of the most cost-effective interventions aimed at reducing infant morbidity and mortality. In addition to the multiple advantages of breast milk in the mother-child bond and biological and immune properties, the most relevant characteristic of breast milk is that it covers all nutritional needs. When breastfeeding is not possible, the World Health Organization recommends infant formula as the first option. The second option is diluted cow's milk, which entails the risk for nutritional deficiency that should be strictly monitored and timely resolved. When infants are fed with diluted cow's milk, they are mainly at risk for iron, zinc, vitamin A, D, C, and E, amino acid, and essential fatty acid deficiency.

ABSTRACT

Introdução:As alergias alimentares são definidas como uma reação imunológica adversa que se repete mediante a exposição a determinado alimento. Essas reações variam da anafilaxia (mais grave) à manifestações gastrointestinais.Objetivo:avaliar a eficácia da suplementação com probióticos no tratamento de alergias alimentares em crianças, na redução dos sintomas e/ou na aquisição de tolerância, identificando cepa mais eficaz, relação dose-resposta e efeitos adversos de seu uso. Metodologia:Esta é uma revisão integrativa de literatura. Para busca de ensaios clínicos e outras revisões, utilizamos as bases científicas ScienceDirect, SciELO, BVS, LILACS, PubMed e MEDLINE, com as palavras-chave "probiotics", "treatment", "food allergy", "children", e "infant". Após a aplicação dos critérios de exclusão, foram selecionados quatro ensaios clínicos randomizados, cinco revisões e uma metanálise; a amostra de todos os estudos foi de lactentes com alergia à proteína do leite de vaca. Resultados:Os estudos apontaram que o uso de fórmula infantil extensamente hidrolisada com Lactobacillus rhamnosus, em doses de 1x106 a 5x108 cfu/g, é eficaz tanto em acelerar a melhora do eczema atópico, como em induzir tolerância em crianças na faixa de idade de 1 mês a 3 anos que não tenham reações anafiláticas ao leite de vaca. Conclusões:Há evidências escassas de que o uso de fórmula infantil extensamente hidrolisada com Lactobacillus rhamnosus, em doses de 1x10


Introduction:Food allergies are defined as an adverse immunological reaction that is repeated through exposure to a particular food. These reactions range from anaphylaxis (more severe) to gastrointestinal manifestations.Objective:To evaluate the effectiveness of probiotics in the treatment of food allergies in children, relieving symptoms or inducing tolerance, identifying the most effective strain, dosage and adverse effects. Methodology:This is an integrative literature review. We performed a systematic search using the keywords "probiotics", "treatment", "food allergy", "children", and "infant" in the following scientific databases: ScienceDirect, SciELO, BVS, LILACS, PubMed, and MEDLINE. After applying the exclusion criteria, we selected four randomized clinical trials, five reviews and one meta-analysis. In all of them, the children were diagnosed with cow's milk allergy. Results:The studies have indicated that the use of extensively hydrolysed milk formula with the addition of Lactobacillus rhamnosus with dosage ranging from 1x106 to 5x108 cfu/g is effective in inducing tolerance and reducing severity of eczema in infants with no history of anaphylactic symptoms. Conclusions:There is limited evidence that the use of extensively hydrolysed milk formula with the addition of Lactobacillus rhamnosus, at doses of 1x10

ABSTRACT

INTRODUCTION: Cow's milk protein allergy requires changes in family habits to maintain children's health. OBJECTIVE: This study evaluated the effects of cow's milk protein allergy on the health of children, the quality of life of parents and children, and the adopted parental styles. METHODS: Control case study. The case group consisted of children with cow's milk protein allergy, from eight months to five years old, and those guardians, and the Control Group, for healthy children of the same age group, and their parents. The quality of life of the child (TNO-AZL Preschool Children Quality of Life) and the caregiver (SF-36) were evaluated; parental style (Parental Beliefs and Care Practices Scale); and socioeconomic and health data of the child. The Mann-Whitney test was used to compare the groups (p <0.05). RESULTS: 76 dyads from the case group and 44 from the control group participated. Children with cow's milk protein allergy had a lower quality of life in the health dimension, worse nutritional status, followed up with a larger number of health professionals. Those in charge of the case group offered less body stimulation to the children. Those in the control group had a lower quality of emotional life CONCLUSIONS: Cow's milk protein allergy had an impact on the health and nutritional status of children, on the corporal stimulation received by the children, and on the quality of emotional life of those guardians.


INTRODUÇÃO: A alergia à proteína do leite de vaca requer alterações dos hábitos familiares para manutenção das condições de saúde das crianças. OBJETIVO: Este estudo analisou os efeitos da alergia à proteína do leite de vaca sobre a saúde de crianças, qualidade de vida de responsáveis e crianças e sobre os estilos parentais adotados. MÉTODO: Estudo caso controle. O grupo caso foi constituído por crianças com alergia à proteína do leite de vaca, de oito meses a cinco anos de idade, e seus responsáveis, e o Grupo Controle, por crianças saudáveis, de mesma faixa etária, e seus responsáveis. Foram avaliadas a qualidade de vida da criança (TNO-AZL Preschool Children Quality of Life) e do responsável (SF-36); estilo parental (Escala de Crenças Parentais e Práticas de Cuidado); e dados socioeconômicos e de saúde da criança. O teste de Mann-Whitney foi utilizado para comparar os grupos (p <0,05). RESULTADOS: Participaram 26 díades do grupo caso e 44 do grupo controle. Crianças com alergia proteína do leite de vaca apresentaram menor qualidade de vida na dimensão saúde, pior estado nutricional, realizaram acompanhamento com maior número de profissionais da saúde. Os responsáveis do grupo caso ofereceram menor estimulação corporal às crianças. Responsáveis do grupo controle apresentaram menor qualidade de vida emocional. CONCLUSÃO: A alergia à proteína do leite de vaca impactou na saúde e no estado nutricional das crianças, na estimulação corporal recebida pelas crianças, e na qualidade de vida emocional dos responsáveis.

ABSTRACT

El raquitismo afecta la diferenciación y mineralización del cartílago de crecimiento como consecuencia, en última instancia, de una alteración en los niveles de fósforo y/o calcio. El secundario a la deficiencia de vitamina D es la forma más frecuente (raquitismo carencial). Las manifestaciones clínicas durante los primeros años de vida suelen comprometer en forma más marcada las epífisis de los huesos.Se describe el caso de un lactante de 8 meses con diagnóstico de alergia a la proteína de la leche de vaca que presentó múltiples fracturas patológicas mientras se encontraba bajo tratamiento con fórmulas lácteas a base de aminoácidos. Se efectuó el diagnóstico de raquitismo hipofosfatémico por deficiencia de fósforo y, tras 3 meses de tratamiento con sales de fosfato, calcio, calcitriol, el abandono paulatino de la leche elemental y el descenso gradual de la medicación antiácida, el paciente evolucionó con curación clínico-radiológica del cuadro


The rickets is a disease that affects the differentiation and mineralization of the growth cartilage, as an ultimate consequence of a balance loss in calcium and phosphate levels. Vitamin D deficiency is the most common cause of the rickets (nutritional rickets). Its clinical manifestation during the first years of life involves long bones epiphysis in a more severe way.We report an 8-month-old infant who was diagnosed with cow ́s milk protein allergy and suffered from multiple fractures while receiving elemental formula as part of his treatment. The final etiology was hypophosphatemic rickets secondary to phosphate deficiency, and after 3 months of phosphate, calcium and calcitriol supplementation, in addition to the gradually reduction of the proportion of elemental formula intake and the decline of the antacid doses, clinical and radiological heal was achieved.
