Hábitos alimentares e estado nutricional de pacientes com doença celíaca do sul do Brasil / Eating habits and nutritional status of patients with celiac disease in south brazil

ABSTRACT Background: Celiac disease is defined as a chronic autoimmune disease that affects the small intestine in genetically predisposed people, triggered by exposure to gluten. The only treatment for celiac disease to date is a lifelong gluten-free diet. Eating habits of celiacs play an important role in their nutritional status. Objective: To evaluate the eating habits and nutritional status of patients with celiac disease in Rio Grande do Sul. Methods: This is a cross-sectional study with patients diagnosed with celiac disease residing in Rio Grande do Sul (Brazil) over 18 years of age. An online questionnaire was applied with calls through social networks and also by the Associação dos Celíacos do Brasil - Rio Grande do Sul Section. Sociodemographic data, history of celiac disease, general medical history, reported weight and height and food consumption data (SISVAN food frequency questionnaire and general questions) were collected. Results: The sample consisted of 142 individuals with a mean age of 39.75±11.5 years, 94.4% were women and 93% were white. The patients showed care regarding a gluten-free diet, with the majority not ingesting gluten (82.2%) and being careful regarding cross-contamination by gluten in their homes (85.9%) and in restaurants (62, 4%). Most patients also had good eating habits, with frequent consumption of fruits, vegetables, meats, eggs and low frequency of processed foods and fats. Body weight before and after the diagnosis of celiac disease did not show significant changes (62.3±13.8 versus 63.6±11.7 kg; P=0.147); however, there was an improvement in the classification of nutritional status by body mass index (malnourished: 11.6% before versus 2.3% after; P=0.016). Conclusion: Most celiac disease patients in this study have good eating habits with a balanced gluten-free diet and improved nutritional status after diagnosis according to body mass index classification.

RESUMO Contexto: A doença celíaca é definida como uma doença crônica autoimune que afeta o intestino delgado em pessoas geneticamente predispostas, desencadeada pela exposição ao glúten. O único tratamento para doença celíaca até o momento é uma dieta isenta de glúten por toda a vida, levando em consideração que os hábitos alimentares de celíacos desempenham um papel importante em seu estado nutricional. Objetivo: Avaliar os hábitos alimentares e o estado nutricional de pacientes com doença celíaca do Rio Grande do Sul. Métodos: Trata-se de um estudo transversal com 142 pacientes com diagnóstico de doença celíaca residentes no Rio Grande do Sul (Brasil) e maiores de 18 anos. Para realização deste estudo, foi aplicado um questionário on-line com divulgação através de redes sociais e também pela Associação dos Celíacos do Brasil - Seção Rio Grande do Sul. Foram coletados dados sociodemográficos, histórico da doença celíaca, história clínica geral, peso e altura referidos e dados de consumo alimentar através de questionário de frequência alimentar do SISVAN e questões gerais. Resultados: A amostra foi constituída por 142 indivíduos com idade média de 39,75±11,5 anos, sendo 94,4% mulheres e 93% de etnia branca. Os participantes apresentaram cuidados em relação a dieta isenta de glúten, sendo que a maioria não ingere glúten (82,2%) e possuem cuidados em relação a contaminação cruzada por glúten em suas casas (85,9%) e em restaurantes (62,4%). A maioria da amostra também apresentou bons hábitos alimentares, com o consumo frequente de frutas, legumes, verduras, carnes, ovos e pouco frequente de industrializados e gorduras. O peso corporal antes e após o diagnóstico de doença celíaca não apresentou mudanças significativas (62,3±13,8 versus 63,6±11,7 kg; P=0,147); entretanto, houve melhora na classificação do estado nutricional pelo índice de massa corporal (11,6% versus 2,3% de desnutridos; P=0,016). Conclusão: A maioria dos pacientes com doença celíaca deste estudo apresentam bons hábitos alimentares com uma dieta isenta de glúten balanceada e com melhora do estado nutricional após o diagnóstico de acordo com a classificação do índice de massa corporal.

Clinical spectrum & changing presentation of celiac disease in Indian children

Background & objectives: Celiac disease (CD) is a genetic immune mediated disorder characterised by gluten intolerance. This single centre study, from north India was aimed to assess the clinical, serological and histological profile of CD in a large cohort of children and the changing trends in its presentation. Methods: A review of clinical details of CD children diagnosed between 2000 and 2019 and currently on follow up was performed. Information on demography, symptoms, associated conditions, serology, biopsy findings and gluten-free diet were analyzed. Results: The mean age (±standard deviation) of 891 children included in the study, at onset and at diagnosis was 4.0±2.7 and 6.2±3.1 yr, respectively. Growth faltering, abdominal pain, abdominal distension and diarrhoea were presenting symptoms in 70, 64.2, 61.2 and 58.2 per cent, respectively. A positive family history of CD was present in 14 per cent and autoimmune conditions in 12.3 per cent of children. Thyroid disorders were seen in 8.5 per cent of children and Type 1 diabetes mellitus (T1DM) in 5.7 per cent. The duration of breastfeeding had a weak positive correlation with age at onset and diagnosis of CD (P<0.001). Non-classical CD was significantly more common in children aged >10 yr and in those presenting after 2010 (P<0.01). T1DM and hypothyroidism occurred more frequently in non-compliant children. Interpretation & conclusions: This was the largest single centre study, pertaining to the presentation and follow up of CD in children. Infants and young children were more likely to present with classical symptoms of diarrhoea, abdominal distension and growth failure while older children presented with non-classical CD. There was a trend towards non-classical forms of CD in recent years.

Coeliac disease knowledge and treatment: Potential factors associated with adherence to gluten-free diet

@#Introduction: Lack of adherence to a strict gluten-free diet (GFD) is the main reason for poorly controlled disease in patients with coeliac disease (CD). This study aimed to assess the association between knowledge of CD and its medical diet to the adherence of GFD among adult patients with CD. Methods: A cross-sectional study was carried out with a total of 90 adult patients with CD (aged between 18-65 years). The data collecting instruments were a combination of four questionnaires as follows: assessment of knowledge of coeliac disease (AKCD), gluten-free diet knowledge scale (GFD-KS), coeliac disease adherence test (CDAT), and questions on potential factors influencing GFD adherence among patients. Results: An average knowledge score of five points out of seven was obtained from 46 participants (51%). Mean score for knowledge on gluten-free diet was seven points out of 17 in 59 participants (65%). Adequate adherence to GFD was observed in 56% of the participants. No association was found between knowledge of CD and GFD to the adherence of GFD (p>0.050). Participants who had higher adherence scores were discussing GFD with a specialist, obtaining educational materials, had enhanced symptoms associated with CD, and did not complain about the taste of GFD (p<0.050). Conclusion: Patients with CD has adequate knowledge of CD and adherence of GFD. No association was found between the knowledge of CD and GFD to the adherence of GFD. Further research might explore other potential factors influencing the adherence to GFD.

Does a Gluten-free Diet Improve Metabolic Syndrome Parameters? A Systematic Review

Abstract To review scientific evidence on the effects of a gluten-free diet on body composition and improvement of clinical and biochemical parameters of metabolic syndrome. The Preferred Reporting Items for Systematic Reviews and Meta-Analyzes - PRISMA guidelines were followed. A literature search was performed in the PubMed, ScienceDirect, Trip Database, Bireme and Scielo databases, without language restriction, until March 2021. The terms "gluten-free diet", "obesity", "metabolic syndrome", and "weight loss", and Boolean operators (AND/OR) were used. The clinical hypothesis was structured according to the acronym PICOT. Randomized clinical trials with adult and elderly humans without a diagnosis of celiac disease, consuming a gluten-free diet, evaluating associations of the effects of this diet on weight loss and metabolic syndrome components were considered eligible. To assess the risk of bias, the RoB2 was used. A total of 3,198 articles were identified and, after the screening and evaluation of pre-defined eligibility criteria, four studies were included in the qualitative analysis. Weight loss was not associated with a gluten-free diet. However, individuals under a gluten-free diet had lower mean waist circumference, fat percentage (-2.3%) and serum triglyceride levels. The impact of a gluten-free diet on metabolic syndrome parameters is still controversial. In individuals without gluten sensitivity or celiac disease, the consumption of a gluten-free diet appears to provide no nutritional benefit.

Conclusion: In the celiac patients studied, poor adherence to the gluten-free diet is associated with worse health-related quality of life.

Sorghum, germinated millet and chia cookies: development, chemical composition and sensory analysis

The objective of this work was to develop cookies using sorghum, germinated millet and chia flours. Four formulations (F) were used: F-sorghum (100% sorghum flour); F-Sorghum + chia (50% sorghum flour and 50% chia flour), F-millet (100% millet flour) and F-millet + chia (50% millet flour and 50% chia flour). The germinated millet flour was submitted to microbiological analysis. All cookies were evaluated in relation to chemical and sensory analyses, according to AOAC and hedonic nine-point scale, respectively. The statistical analysis was performed by the variance analysis and Tukey test at 5% probability. The F-millet formulation showed the least humidity content (4.59 ± 0.25g/100g), while chia containing cookies showed lesser concentrations of carbohydrates (F-sorghum + chia: 44.35 ± 4.34g/100g and F-millet + chia: 41.03 ± 1.40g/100g) and higher ash content (F-sorghum + chia: 3.80 ± 0.02g/100g and F-millet + chia: 3.42 ± 0.24g/100g) and of protein (F-sorghum + chia: 15.38 ± 0.44 g/100g and F-millet + chia: 18.06 ± 0.53 g/100g). The caloric value and the lipids content did not differ among formulations. The sensory analysis had 57 evaluators. The cookies produced with chia and germinated millet had higher rates for flavor, texture and general impression. In general, all tested biscuits had good sensory acceptance and nutritional quality being an alternative to increase the consumption of bioactive compounds and antioxidants(AU)

El objetivo fue desarrollar galletas utilizando harina de sorgo, mijo germinado y chía. Se utilizaron cuatro formulaciones (F): F-sorgo (100% harina de sorgo); Sorgo F + chía (50% harina de sorgo y 50% harina de chía), mijo F (100% harina de mijo) y mijo F + chía (50% harina de mijo y 50% harina de chía). La harina de mijo germinada se sometió a análisis microbiológico. Las galletas fueron sometidas a análisis químico y sensorial, según la AOAC y una escala hedónica de nueve puntos, respectivamente. El análisis estadístico se realizó mediante análisis de varianza y prueba de Tukey al 5% de probabilidad. La formulación F-mijo tuvo menor contenido de humedad (4,59 ± 0,25 g/100g), mientras que las galletas que contenían chía tuvieron concentraciones más bajas de carbohidratos (F-sorgo + chía: 44,35 ± 4,34 g/100g y F-mijo + chía: 41,03 ± 1,40 g / 100g), mayor contenido de cenizas (F-sorgo + chía: 3,80 ± 0,02 g/100g y F-mijo + chía: 3,42 ± 0,24 g/100g) y proteínas (F-sorgo + chía: 15,38 ± 0,44 g/100g y F mijo + chía: 18,06 ± 0,53 g/100g). El valor calórico y el contenido de lípidos no difirieron entre las formulaciones. El análisis sensorial contó con 57 evaluadores. Las galletas producidas con chía y mijo germinado tenían notas más altas de sabor, textura e impresión general. Las galletas testadas tuvieron buena aceptación sensorial y calidad nutricional, siendo una alternativa para incrementar el consumo de compuestos bioactivos y antioxidantes(AU)

Características clínicas, demográficas y acceso a los productos sin gluten de pacientes con enfermedad celíaca registrados en la FUPACEL / Clinical and demographic characteristics, and access to gluten free products of patients with celiac disease registered in the FUPACEL

La enfermedad celíaca (EC) es una enfermedad inflamatoria autoinmune que afecta la mucosa del intestino delgado que lleva a un estado de mal absorción en pacientes genéticamente susceptibles desencadenada por la ingesta de gluten. Tiene síntomas inespecíficos, complicaciones asociadas y no existe a nivel nacional una ley de apoyo económico para las personas con dificultad para seguir una dieta libre de gluten. El objetivo de este estudio observacional, descriptivo, de corte transversal fue describir las características clínicas, demográficas y acceso a productos sin gluten de 237 pacientes con enfermedad celíaca registrados en la Fundación Paraguaya de Celiacos (FUPACEL) en el 2020 y que aceptaron responder una encuesta en línea publicada en la página oficial de la FUPACEL. El 70,4% de los participantes era del sexo femenino, la edad de diagnóstico fue en el 34,5% entre 20-30 años, 48 % tenía algún familiar con EC, el 69,1% presentó distensión abdominal como sintomatología inicial, 16,8% presentó hipotiroidismo como patología asociada, y 42% fue hospitalizado al menos una vez. El 82,7% de los encuestados respondió que la dieta era suficiente como tratamiento, 48% tenía un trabajo y podía solventar los gastos, sin embargo, el 79,3% opinó tener acceso limitado a los productos sin gluten, el 92% que los alimentos sin gluten eran costosos y que se necesitaba una ley de apoyo económico para solventar los gastos. La mayoría reconoció que la dieta sin gluten como tratamiento era suficiente, sin embargo, por su alto costo se necesita una ley de apoyo económico para las personas con enfermedad celiaca

Celiac disease (CD) is an autoimmune inflammatory disease that affects the mucosa of the small intestine that leads to a state of malabsorption in genetically susceptible patients triggered by the ingestion of gluten. It has nonspecific symptoms, associated complications, and there is no national financial support law for people with difficulty following a gluten-free diet. The objective of this observational, descriptive, cross-sectional study was to describe the clinical, demographic characteristics and access to gluten-free products of 237 patients with celiac disease registered in the FUPACEL in 2020 who accepted to answer a online survey published in the official FUPACEL webpage. Seventy-point four percent of the patients were female, their age of diagnosis was between 20-30 years in 34.5%, 48% had relatives with CD, 69.1% presented abdominal distension as initial symptoms, hypothyroidism was present in 16.8% as associated pathology, and 42% were hospitalized at least once. Eighty-two-point seven percent of those surveyed answered that diet was sufficient as a treatment, 48% had a job and could afford expenses, however, 79.3% said they had limited access to gluten-free products, 92% that gluten-free foods were expensive and a financial support law was needed to cover the costs. Most recognized that a gluten-free diet as a treatment was sufficient, however, due to its high cost, a law of financial support is needed for people with celiac disease

Factores que limitan la adherencia a la dieta y la calidad de vida en enfermos celiacos chilenos durante COVID-19 / Factors that limit adherence to diet and quality of life in Chilean celiac patients during COVID-19

La enfermedad por coronavirus (COVID-19) es altamente contagiosa y las medidas de confinamiento dinámico han demostrado que reducen significativamente el número de contagios, sin embargo, pueden alterar la disponibilidad de alimentos afectando la adherencia a la dieta libre de gluten (DLG) y la calidad de vida (CV) en la enfermedad celiaca (EC). El objetivo de este estudio fue evaluar los factores que limitan, la adherencia a la dieta libre de gluten y la calidad de vida en personas con enfermedad celiaca en periodo de pandemia por COVID-19. Métodos Se aplicaron encuestas on-line respecto a adherencia a la DLG, CV y acerca de los factores que han generado dificultad para llevar una DLG en este escenario. Resultados Se analizaron 216 encuestas de enfermos celiacos, mayores de 15 años, de los cuales un 91% eran mujeres con un promedio de edad de 36 + 10,7 años y con 5,8 + 6,0 años de enfermedad. El 56,48% tenía una excelente adherencia a la DLG y un 43,52% una buena CV. El costo elevado de los alimentos sin gluten fue la pregunta con mayor porcentaje de respuesta, asociándose con regular y mala adherencia a la DLG (valor p=0,001) y con pobre CV (valor p=0,023). Conclusión En periodo de pandemia por COVID-19, el costo de los alimentos se asocia con adherencia regular y mala a la DLG y con pobre CV(AU)

Coronavirus disease (COVID-19) is highly contagious and dynamic confinement measures have shown to significantly reduce the number of infections, however, they can alter the availability of food, affecting adherence to a gluten-free diet (GFD) and quality of life (QoL) in celiac disease (CD). The objective of this study was to evaluate the limiting factors, adherence to a gluten-free diet and quality of life in people with celiac disease in a COVID-19 pandemic period. Methods. On-line surveys were applied regarding adherence to the GFD, CV, and factors that have generated difficulty in carrying out a GFD in this setting. Results. 216 surveys of celiac patients over 15 years of age were analyzed, of which 91% were women with an average age of 36 + 10.7 years and with 5.8 + 6.0 years of the disease. 56.48% had excellent adherence to the GFD and 43.52% had a good QoL. The high cost of gluten-free foods was the question with the highest response percentage, associated with regular and poor adherence to the GFD (p-value = 0.001) and with poor QoL (p-value = 0.023). Conclusion. In a COVID-19 pandemic period, the cost of food is associated with regular and poor adherence to the GFD and with poor QoL(AU)

Detección de trazas de soja y de leche en productos libres de gluten: desarrollo de dos enzimoinmunoensayos competitivos / Detection of traces of soy and milk in gluten-free products: development of two competitive enzyme immunoassays / Detecção de vestígios de soja e leite em produtos livres de glúten: desenvolvimento de dois enzimoimunoensaios competitivos

Resumen El objetivo del presente trabajo fue el desarrollo de dos enzimoinmunoensayos competitivos (EIC) para la detección de trazas de soja y de leche en productos libres de gluten. Como anticuerpos primarios se utilizaron antisueros policlonales de conejo específicos contra proteínas de soja o de leche. Se determinaron las concentraciones óptimas de antígenos a inmovilizar en la placa y las concentraciones de anticuerpos primarios a utilizar en la competencia. Las curvas de calibración se ajustaron utilizando concentraciones crecientes de un extracto de producto de soja y de un extracto de leche descremada en polvo. El producto de soja y la leche descremada se extrajeron con buffer Tris-HCl 0,0625 M con dodecilsulfato de sodio al 3% y sulfito de sodio 0,1 M al 2%. Se evaluaron los parámetros de validación: linealidad, límites de detección y de cuantificación, recuperación y precisión en el día y entre días, los cuales resultaron adecuados. Se analizaron 9 productos libres de gluten con los EIC desarrollados y con kits de ELISA comerciales. Ambos EIC se comportaron de manera similar con respecto a los kits comerciales. Los EIC permitieron confirmar la presencia de leche en las muestras que la declaraban. En algunas muestras que no declaraban ni leche ni soja, ambos EIC detectaron su presencia (resultados confirmados con los kits comerciales). Los EIC desarrollados poseen menor costo que los kits y, por lo tanto, éstos podrían utilizarse como métodos de screening. Cuando esta metodología resulte negativa, debe confirmarse con un método más sensible (comercial) para garantizar la ausencia de proteínas de soja o de leche.

Abstract The aim of this study was to develop two competitive enzyme immunoassays (CEI) to detect the presence of traces of soy and milk in gluten-free products. Specific rabbit polyclonal antiserums against soy protein and other against elemilk protein were used as primary antibodies. Optimal antigen concentrations to be immobilized on the plate and primary antibody concentrations to be used in competition were determined. The calibration curves were fitted using increasing concentrations of an extract of soy product and of defatted milk powder. The soy product and the defatted milk were extracted with Tris-HCl buffer 0,0625 M with 3% sodium dodecyl sulfate and 2% sodium sulfite 0.1 M. The validation parameters were evaluated: linearity, limit of detection and quantification, recovery and precision on the day and in between days. They were appropriate. Nine commercial samples of gluten-free products were analyzed with these developed CEI and commercial ELISA kits. It was observed that both CEI behaved similarly with respect to the commercial kits. The enzyme immunoassays confirmed the presence of milk in samples that declared it. In some samples that did not declare the presence of milk or soy, both enzyme immunoassays detected their presence -these results were confirmed using commercial kits. The developed CEI have a lower cost than the commercial kits, so these could be used as screening methods. When this methodology is negative, it should be confirmed with a more sensitive (commercial) method to ensure the absence of soy or milk protein.

Resumo O objetivo do presente trabalho foi o desenvolvimento de dois enzimoimunoensaios competitivos (EIC), para a detecção de vestígios de soja e leite em produtos livres de glúten. Antissoros policlonais de coelho específicos contra proteínas de soja ou de leite foram utilizados como anticorpos primários. Foram determinadas as concentrações ótimas de antígenos a serem imobilizados na placa e as concentrações de anticorpos primários a serem utilizadas na competição. As curvas de calibração foram ajustadas usando concentrações crescentes de um extrato de produto de soja e de um extrato de leite em pó desnatado. O produto de soja e o leite desnatado foram extraídos com tampão Tris-HCl 0,0625 M com dodecil sulfato de sódio a 3% e sulfito de sódio 0,1 M a 2%. Os parâmetros de validação foram avaliados: linearidade, limite de detecção e quantificação, recuperação e precisão no dia e entre os dias, os quais resultaram adequados. Nove produtos livres de glúten foram analisados com os EIC desenvolvidos e com kits de ELISA comerciais. Os dois EICs se comportaram de maneira semelhante em relação aos kits comerciais. Os EIC permitiram confirmar a presença de leite nas amostras que o declararam. Em algumas amostras que declaravam nem leite nem soja, ambos os EIC detectaram sua presença (resultados confirmados usando kits comerciais). Os EIC desenvolvidos têm um custo menor que os kits, portanto, eles poderiam ser utilizados como métodos de triagem. Quando esta metodologia é negativa, deve ser confirmada com um método mais sensível (comercial) para garantir a ausência de proteínasda soja ou do leite.

Conhecimento de estudantes de Gastronomia acerca da doença celíaca / Knowledge of Gastronomy students about celiac disease

Objetivo: Avaliar o conhecimento de estudantes do curso de Gastronomia acerca da doença celíaca. Métodos: Estudo descritivo realizado com estudantes de um curso de Tecnologia em Gastronomia de Dourados-MS. Coleta de dados realizada em abril de 2019, por meio da aplicação de questionário organizado em três seções: (1) Sociodemográfica; (2) Conhecimento acerca da doença celíaca e dieta isenta de glúten; e (3) Conhecimento sobre cuidados especiais em preparações culinárias para celíacos. Resultados: Participaram 60 estudantes, com média de idade de 31,5 anos, sendo a maioria do sexo feminino (70%) e tendo se autodeclarado branca (73,3%). A maioria já ouviu falar da doença celíaca e glúten (61,7% e 100%, respectivamente), todavia 66,1% responderam erroneamente ou não souberam responder sobre o conceito da doença. Somente 15,5% acertaram que glúten é uma proteína. Apenas 24,5% dos estudantes mencionaram corretamente todos os cereais que contêm glúten e 5,4% indicaram corretamente todas as opções de substitutos para os cereais com glúten. Embora a maioria tenha relatado práticas convergentes sobre cuidados especiais em preparações isentas de glúten, um número expressivo de estudantes errou ou não soube responder sobre o compartilhamento de óleo, utensílios/equipamentos entre alimentos com e sem glúten (31,6% e 41,7%, respectivamente). Aproximadamente um terço dos estudantes (31,6%) não considera necessário verificar a presença de glúten no rótulo dos alimentos. Conclusão: Os estudantes de Gastronomia apresentaram conhecimento insatisfatório acerca da doença celíaca, dieta isenta de glúten e práticas culinárias para evitar a contaminação cruzada por glúten, o que pode implicar futuramente a qualidade dos serviços prestados na área de alimentação por esses profissionais e, consequentemente, na qualidade de vida dos celíacos. Os achados indicam a necessidade de reforma do currículo e criação de diretrizes curriculares para os cursos de Tecnologia em Gastronomia no Brasil. (AU)

Data collection was carried out in April 2019 through the application of a questionnaire organized in three sections with open and closed questions: (1) Sociodemographic issues; (2) Knowledge about celiac disease and gluten-free diet and (3) Knowledge about special care in culinary preparations for people with celiac disease. Results: Sixty students with an average age of 31.5 years old participated, most of them female (70%) and self- declared white (73.3%). Most of them have heard of celiac disease and gluten (61.7% and 100%, respectively) although the majority (66.1%) answered wrongly or was not able to answer about the concept of celiac disease. Only 15.5% believed that gluten is a protein. Only 24.5% of students correctly mentioned all the gluten-containing cereals and 5.4% correctly indicated all options to replace them. Although most of the students reported converging special care practices in gluten-free preparations, a significant number of students were wrong or not able to answer about sharing oil, utensils, and equipment for gluten and gluten-free foods (31.6% and 41.7% respectively). Approximately one-third of the students (31.6%) did not consider it necessary to verify the presence of gluten on food labels. Conclusion: The Gastronomy students present unsatisfactory knowledge about celiac disease, gluten-free diet, and culinary practices to prevent cross-contamination by gluten, which may affect the future quality of food services provided by these professionals and, consequently, in the quality of life of celiac consumers. The findings indicate the need to reform the curriculum and create curricular guidelines for Technology in Gastronomy courses in Brazil. (AU)

La dieta libre de gluten, ¿se diferencia de la alimentación general?: Estudio comparativo entre niños celíacos y no celíacos / Does the Gluten Free Diet differ from the general diet?: Comparative study between celiac and non-celiac children

Introducción: la enfermedad celíaca (EC) es una patología multisistémica, precipitada por la ingesta de gluten que requiere de la eliminación de por vida de los alimentos que lo contienen con el fin de mejorar la sintomatología. Sin embargo, esta supresión alimentaria podría alejar a quienes la padecen de los requerimientos nutricionales recomendados. El objetivo del presente estudio fue conocer la ingesta promedio de macronutrientes en los/as niños/as celíacos/as con dieta libre de gluten (DLG) y compararla con la alimentación de niños/as no celíacos/as. Materiales y método: el estudio se llevó a cabo en población celíaca y no celíaca (grupo control) de 6 a 11 años de ambos géneros. En ella se realizó la evaluación del consumo alimentario a través de dos recordatorios de 24 hs. Se utilizó como análisis estadístico la prueba Bayesiana de Estimación de una Diferencia de Medias - Método Exacto. Resultados: se estudiaron 40 celíacos y 40 no celíacos. No se observaron diferencias significativas en el nivel socioeconómico, ni en el estado nutricional. Se observó que la mayoría de los celíacos sobrepasaron las recomendaciones de hidratos de carbono y proteínas, al igual que el grupo control. Conclusión: la DLG realizada por los niños de 6 a 11 años presenta un mayor y excesivo consumo de hidratos de carbono y grasas en comparación con las IDR.

Introduction: Celiac Disease (CD) is a multisystem pathology, caused by gluten intake, and requires the elimination of gluten food for life to improve symptoms. However, this dietary suppression could keep celiac away from the recommended nutritional requirements. The objective of the present study was to know the average intake of macronutrients in celiac children with a gluten-free diet (DLG) and compare it with the diet of non-celiac children. Materials and Methods: the study was carried out in celiac and non- celiac population (control group) of 6 to 11 years old, of both genders. In it, the evaluation of food consumption was made through two 24-hour reminders. The Bayesian test of Estimation of Difference of Means - Exact Method was used as statistical analysis. Results: 40 celiac and 40 non-celiac were studied. There were no significant differences in socioeconomic status or nutritional status. It was observed that the majority of celiacs exceeded carbohydrate and protein recommendations, as did the control group. Conclusion: the GFD performed by celiac children aged 6 to 11 years old presents a grater and excessive consumption of carbohydrates and fats compared to RDI.

Alimentos potenciales a base de yuca y camote como fuente de carbohidratos complejos para contribuir en la dieta de personas con intolerancia al gluten / Potential foods based on yucca and sweet potato as a source of complex carbohydrates to contribute to the diet of people with gluten intolerance

Esta investigación de campo se enfocó en hacer un estudio sobre la alimentación de las personas celiacas en El Salvador asociadas en ACELYSES. Se propuso un recetario de alimentos libres de gluten como fuente de carbohidratos complejos, a base de yuca, camote y otros vegetales inocuos para contribuir en la dieta de personas con intolerancia al gluten (celíacos). Para la elaboración de las 27 recetas fue necesario dar prioridad a la inocuidad y control de la contaminación cruzada, es decir, que los alimentos no hayan sido contaminados con gluten en ningún proceso. Otro aspecto importante fue analizar la trazabilidad de las materias primas que se deben utilizar para preparar los alimentos, así como los utensilios con los que se preparan, a fin de evitar riesgos a las personas con esta patología. Se realizaron pruebas sensoriales y hedónicas a través de focus group para obtener la opinión de aceptación de las recetas propuestas; igualmente, se elaboró una tabla con el contenido nutricional de cada receta, lo cual permitirá al usuario informarse del consumo de grasas, carbohidratos y otros minerales en beneficio de su salud.

This field research was focused on conducting a study of the diet of people with celiac disease in El Salvador associated with ACELYSES. A recipe book for gluten-free foods was proposed as a source of complex carbohydrates, based on yucca, sweet potato and other harmless vegetables to contribute to the diet of people with gluten intolerance (celiacs). For the preparation of the 27 recipes, it was necessary to give priority to safety and control of cross contamination, that means that the food had not been contaminated with gluten in any process. Another important aspect was to analyze the traceability of the raw materials that should be used to prepare food, as well as the utensils with which they are prepared, in order to avoid risks to people with this pathology. Sensory and hedonic tests were carried out through focus groups to obtain the opinion of acceptance of the proposed recipes; Likewise, a table was prepared with the nutritional content of each recipe, which can allow the user to find out about the consumption of other fats, carbohydrates and minerals for the benefit of their health.

Intussusception associated with celiac disease in a child: case report and review of literature

Intussusception and celiac disease both are common in children.' Intussusception has been rarely associated with celiac disease in children, which mostly involved small bowel, are transient without classical symptoms, reduced spontaneously and rarely needs intervention. Authors are reporting a 2-year girl who presented initially as gastroenteritis and later on intestinal obstruction and on investigation revealed ileo-ileal intussusception which resolved spontaneously during laparotomy preparation. The patient had growth retardation and microcytic hypochromic anemia and on further evaluation diagnosed with celiac disease. This case report highlights the need of celiac testing in children with intussusception, and such intussusception resolved spontaneously with gluten free diet and rarely needs any active intervention, thus preventing from undue nonsurgical or surgical interventions for intussusception.

Response to gluten free diet in sero-positive celiac disease children suffering from severe acute malnutrition in age group 1-5 years

Background: Diagnosis of celiac disease in children suffering from severe acute malnutrition without duodenal biopsy or HLA typing is a dilemma. The objective of this study was to study the response to gluten free diet in sero-positive Celiac Disease children suffering from severe acute malnutrition in age group 1-5 years.Methods: This prospective, observational, hospital-based study was conducted at MTC of tertiary care medical college hospital of southern Rajasthan from Dec. 2017 to Nov. 2018. Total 110 children with SAM were enrolled and screened for celiac disease on the basis of tissue tTg-IgA/IgG serology. Seropositive cases were kept on gluten free diet for short period of time and observed for the resolution of symptoms and improvement in growth, monitored by anthropometry on discharge and follow up visit.Results: Mean weight gain (gm/kg/day) on follow up was 3.87'3.49 in seropositive and 1.88'3.79 in seronegative cases (P-value<0.05). Mean weight gain was 6.43'3.28gm/kg/day in only tTg-IgA positive and 3.04'2.95 gm/kg/day in only tTg-IgG positive cases (P-value-<0.05). The mean weight gain in strictly gluten free adherent sero-positive cases was 4.89'2.97 gm/kg/day while in gluten free non-adherent patients it was -0.49'1.70 (P-value <0.001). Mean weight gain in probable (tTg-Ig-A <10 times ULN) and presumptive (tTg-IgA >10 times ULN) Celiac disease were 3.44'3.73 and 5.44'3.78, respectively without statically significant difference (P-value >0.05).Conclusions: In situations where facility of duodenal biopsy and or HLA DQ2/DQ8 typing is not available, resolution of symptoms and improvement in growth on gluten free diet confirms the diagnosis of celiac disease.

Prevalencia de anticuerpos anti-Saccharomyces cerevisiae en pacientes celíacos / Prevalence of anti-Saccharomyces cerevisiae antibodies in celiac patients / Prevalência de anticorpos anti-Saccharomyces cerevisiae em pacientes celíacos

La enfermedad celíaca (EC) es una condición inflamatoria crónica del intestino delgado causada por intolerancia al gluten. El tratamiento consiste en la dieta libre de gluten (DLG). Los anticuerpos anti Saccharomyces cerevisiae (ASCA) están dirigidos contra la pared celular de la levadura, se asocian a enfermedades autoinmunes, y se propone la permeabilidad intestinal alterada como causa de activación de la inmunidad humoral. El objetivo del trabajo fue determinar la prevalencia de ASCA IgG e IgA en pacientes celíacos bajo tratamiento y evaluar la asociación de ASCA con el grado de adherencia a la DLG. Se analizaron 59 sueros de pacientes adultos celíacos con alta o baja adherencia a la DLG, y se determinó ASCA IgG e IgA. Se halló una prevalencia de ASCA IgG y/o IgA del 44%. Se encontró asociación entre ASCA-IgG y adherencia a DLG (OR 4,04 IC 95%: 1,32-12,38). La prevalencia de ASCA en la población celíaca estudiada es similar a la reportada en la bibliografía. La menor prevalencia de ASCA IgG en pacientes con una estricta DLG respecto de aquellos con baja adherencia, indicaría que su presencia depende del nivel de ingesta de gluten, sugiriéndolos como herramienta complementaria en el seguimiento del paciente celíaco.

Celiac disease (CD) is a chronic inflammatory condition of the small intestine caused by gluten intolerance. The treatment consists of gluten free diet (GFD). Anti Saccharomyces cerevisiae antibodies (ASCA) are directed against the cell wall of yeast, associated with autoimmune diseases, and an altered intestinal permeability is proposed as a cause of activation of humoral immunity. The objective of this work was to determine the prevalence of IgG and IgA ASCA in celiac patients under treatment and to evaluate the association of ASCA with the degree of adherence to GFD. Fifty-nine serum samples from adult celiac patients with high or low adherence to GFD were analyzed, determining IgG and IgA ASCA. A 44% prevalence of IgG and/or IgA ASCA was found. An association was discovered between IgG ASCA and GFD adherence (OR 4.04, 95% CI: 1.32-12.38). The prevalence of ASCA in the studied celiac population is similar to that reported in the literature. The lower prevalence of IgG ASCA in patients with a strict GFD compared to those with low adherence would indicate that their presence depends on the level of gluten intake, suggesting them as a complementary tool in the follow-up of the celiac patient.

A doença celíaca (DC) é uma condição inflamatória crônica do intestino delgado causada pela intolerância ao glúten. O tratamento consiste na dieta sem glúten (DSG). Os anticorpos anti Saccharomyces cerevisiae (ASCA) são dirigidos contra a parede celular da levedura, associados a doenças autoimunes, e à permeabilidade intestinal alterada como causa da ativação da imunidade humoral. O objetivo foi determinar a prevalência de ASCA IgG e IgA em pacientes celíacos em tratamento; avaliar a associação de ASCA com o grau de adesão ao DSG. Foram analisados 59 soros de pacientes celíacos adultos com alta ou baixa adesão ao DSG, determinando ASCA IgG e IgA. Foi encontrada uma prevalência de SCA IgG/ou IgA de 44%. Foi encontrada uma associação entre ASCA-IgG e a adesão ao DSG (OR 4,04 IC 95% 1,32-12,38). A prevalência de ASCA na população celíaca estudada é semelhante à relatada na literatura. A menor prevalência de ASCA IgG em pacientes com rigorosa DSG, em comparação àqueles com baixa adesão, indicaria que sua presença depende do nível de ingestão de glúten, sugerindo-os como uma ferramenta complementar no seguimento do paciente celíaco.

Eficacia de la dieta libre de gluten en el síndrome Gilles de la Tourette con enfermedad celíaca. Reporte de caso / Efficacy of the gluten-free diet in the Gilles de la Tourette syndrome with celiac disease. Case Report

RESUMEN Fundamentación: El síndrome Gilles de la Tourette es un proceso neuropsiquiátrico de causa desconocida caracterizado por múltiples tics. Los desórdenes relacionados al gluten cubren múltiples manifestaciones clínicas inmunológicas ante el consumo de gluten; incluyen la enfermedad celíaca y la sensibilidad al gluten no celíaca. Se han publicado casos de síndrome Gilles de la Tourette con sensibilidad al gluten no celíaca, pero ninguno relacionado con la enfermedad celíaca clásica. Reporte de caso: Paciente masculino de 20 años, con diagnóstico de EC desde la infancia y cuadro típico de Tourette diagnosticado recientemente. Mostró excelente respuesta y remisión clínica neurológica y conductual después de establecerse rigurosamente una dieta libre de gluten. Conclusiones: Es necesario incluir entre los grupos de riesgo de sensibilidad al gluten los niños con trastornos neuropsicológicos como los aquí referidos. La enfermedad celíaca clásica debe incluirse entre las posibles asociaciones con el síndrome Gilles de la Tourette. La dieta restrictiva también mejora en estos casos la evolución de ambas enfermedades.

ABSTRACT Background: The Gilles de la Tourette syndrome is a neuropsychiatric process of unknown cause characterized by multiple tics. Disorders related to gluten cover multiple immunological clinical manifestations when eating gluten; they include celiac disease and non-celiac gluten sensitivity. There have been cases of Gilles de la Tourette syndrome with sensitivity to non-celiac gluten, but none related to classic celiac disease. Case report: A 20-year-old male patient, with a CD diagnosis from childhood and typical GTS pattern recently diagnosed. He showed excellent response and clinical neurological and behavioral remission after rigorously establishing a gluten-free diet. Conclusions: Children with neuropsychological disorders such as those referred here need to be included among the risk groups with gluten sensitivity. Classical celiac disease should be included among the possible associations with the Gilles de la Tourette syndrome. The restrictive diet also improves the evolution of both diseases in these cases.

Efectos de la edad al momento del diagnóstico y cumplimiento de la dieta sobre los parámetros de crecimiento de los pacientes con celiaquía / Effects of age of diagnosis and dietary compliance on growth parameters of patients with celiac disease

Introducción. El objetivo fue evaluar la relación entre edad al diagnóstico y cumplimiento de dieta sin gluten (DSG) y su efecto sobre el crecimiento de niños celiácos y factores que influenciaron el cumplimiento de la DSG. Población y métodos. Se incluyeron pacientes celíacos con seguimiento en nuestro hospital entre enero 2015 a enero 2017. Se los clasificaron según edad al diagnóstico y cumplimiento de la DSG. Se compararon características antropométricas al diagnóstico y durante el seguimiento. Resultados. Participaron 73 pacientes con edad promedio de 10,4 ± 4,5 años; 35 (47,9%), los pacientes de talla baja al diagnóstico; eran mayores (7,8 ± 4,2 años) que los demás (5,1 ± 4,3 años de edad) (p= 0,005). Al diagnóstico, 33 (45,2%) pacientes tenían ≤6 años y 40 (54,8%) tenían >6 años. Los puntajes Z de estatura y peso a la edad >6 años eran significativamente menores que los diagnosticados a ≤6 años, en el diagnóstico (p= 0,01 y 0,04, respectivamente) como en el último control (p= 0,001 y 0,001, respectivamente). Tuvieron cumplimiento riguroso con DSG en 45 (61,6%) pacientes. Al comparar datos antropométricos , el aumento del índice de masa corporal (IMC) y del puntaje Z de peso en el grupo que cumplió la dieta fue significativamente mayor que en el otro grupo.Conclusiones. Demorar el diagnóstico de celiaquía afectó la estatura y peso. El cumplimiento de la DSG mejoró los parámetros de crecimiento, principalmente, el puntaje Z de peso y el IMC.

Introduction. The objective of this study was to evaluate the relation between age at diagnosis and compliance to gluten free diet (GFD) on growth in children with celiac disease and the factors that influenced compliance to GFD. Population and Methods. Celiac disease (CD) patients with villous atrophy followed in our hospital between January 2015 and January 2017, were included. They were classified according to diagnosis age and GFD compliance. Patients' anthropometric characteristics at diagnosis and follow-up were compared. Results. There were 73 patients with 10.4 ± 4.5 years of average age, 35 (47.9%) patients had a short stature at diagnosis, the ages of patients who had short stature (7.8 ± 4.2 years) were higher than those who did not (5.1 ± 4.3 years) (p= 0.005). At diagnosis, 33 (45.2%) patients were aged ≤6 years, 40 (54.8%) were aged >6 years. The height and weight z-scores of patients who were diagnosed at >6 years of age were significantly lower than those who were diagnosed ≤6 years of age both at diagnosis (p= 0.01 and 0.04) and at last control (p= 0.001 and 0.001), respectively. Forty-five (61.6%) patients were fully compliant with GFD. In comparison of anthropometric data in terms of GFD compliance, the increase in BMI and weightz-score in the fully compliant group was found to be significantly higher when compared with the other group. Conclusions. Delay in CD diagnosis negatively affected both the height and weight and other growth parameters. GFD compliance positively affected the patients' all growth parameters, especially weight and BMI z-score.

Factores que inciden en la adherencia a la dieta libre de gluten en adultos celíacos de la Ciudad Autónoma de Buenos Aires / Factors that have an impact on adherence to gluten-free diet in celiac adults in Buenos Aires City

Introducción: la dieta libre de gluten (DLG) es el único tratamiento disponible para la enfermedad celíaca (EC). El objetivo de este trabajo es describir la perspectiva de los usuarios de los servicios de la Dirección General de Desarrollo Saludable (DGDS) con EC con respecto a la realización de la dieta. Materiales y método: estudio descriptivo de corte transversal. Entre septiembre de 2015 y diciembre de 2016, se realizaron encuestas autoadministradas a personas con diagnóstico de EC, usuarias de servicios de la DGDS. Resultados: se encuestaron 271 personas (89,3% mujeres; 10,9% hombres). La mayoría con nivel educativo alto (43,2%) o medio (54,6%), residentes en la CABA (71,6%). El 78,6% había realizado algún control por la EC en los últimos 12 meses y el 77,8% había asistido alguna vez al nutricionista para consultar sobre la DLG. El 28,4% participaba en alguna asociación de celíacos, las que a su vez fueron las fuentes de información más confiables (61,9%), seguidas por médicos (58,7%) y nutricionistas (51,2%). El símbolo oficial fue la estrategia más utilizada para identificar alimentos libres de gluten. Comer fuera del hogar y viajar fueron las situaciones de mayor dificultad para la realización de la DLG y el costo de los alimentos es percibido como un factor que la obstaculiza. Con respecto a la percepción sobre el nivel de adherencia a la DLG, el 71,8% de los encuestados consideró que adhería totalmente. Para describir el sentimiento originado por tener que realizar la DLG, las palabras más mencionadas fueron aceptación, placer, bienestar, enojo, impotencia, trastorno y agotamiento (45,3% fueron términos asociados a sentimientos positivos y 54,7% a sentimientos negativos). Conclusión: la DLG impone dificultades a las personas con EC. Conocer las percepciones y las estrategias que emplean para poder adherir a la dieta es de gran utilidad en el diseño de intervenciones.

Introduction: the gluten-free diet (GFD) is the only available treatment for celiac disease (CD). The objective of this work is to describe the perspectives of the users of CD services given by the Directorate-General for Health Development (DGHD) with respect to the fulfillment of GFD. Materials and Method: cross-sectional study. Between September 2015 and December 2016 self-reported surveys were carried out on people diagnosed with CD, also users of the services given by DGHD. Results: 271 people (89.3% female; 10.9% male) participated in the survey. The majority presented high (43.2%) or middle (54.6%) level of education and resided in Buenos Aires City (71.6%). 78.6% had carried out at least one CD control in the previous 12 months and 77.8% had previously consulted with a nutritionist regarding GFD. 28.4% participated in some CD association, which was the most reliable source of information (61.9%), followed by doctors (58.7%) and nutritionists (51.2%). The official symbol was the most common strategy used to identify gluten-free products. Eating out and traveling were the situations which entailed the greatest difficulties for GFD fulfillment, and the cost of gluten-free products was perceived as an obstacle. With respect to the perception upon the level of adherence to the GFD, 71.8% of participants considered they totally adhered. When describing the feelings originated as a consequence of GFD, the most mentioned were acceptance, pleasure, wellbeing, anger, helplessness, disorder and exhaustion (45.3% were terms associated with positive feelings and 54.7%, with negative feelings). Conclusions: GFD entails difficulties in people with CD. Obtaining insight on the perceptions and strategies followed in order to fulfill the diet is of great use in the design of interventions.
