ABSTRACT
Resumen:Introducción: La piedra angular del tratamiento de alergia alimentaria es la eliminación de los alimentos causantes. Sin embargo, los niños que restringen el consumo de alimentos básicos tienen un mayor riesgo de desnutrición.El objetivo del estudio fue identificar el estado nutricional de pacientes con dieta de eliminación e identificar la proporción de pacientes del grupo con verdadera alergia alimentaria.Métodos: Se realizó un estudio transversal de enero a octubre de 2014 en el Hospital Infantil de México Federico Gómez. Se incluyeron pacientes de 1 a 11 años con historia de eliminación de, al menos, uno de cinco alimentos (huevo, leche, trigo, maíz, soya) por un mínimo de 6 meses. Se realizó la valoración nutricional completa y se compararon los índices antropométricos con tablas de Z score para la edad. Se analizaron los datos por medio de estadística descriptiva, y posteriormente con prueba de Kruskal-Wallis y correlación de Spearman.Resultados: Los alimentos más frecuentemente eliminados fueron leche, soya, huevo, maíz y trigo. Al comparar el número de alimentos eliminados de la dieta con los distintos índices antropométricos evaluados, se encontró que entre mayor cantidad de alimentos eliminados, el score Z de peso para la edad (PE) y talla para la edad (TE), así como peso para la talla (PT) fueron menores, y el más afectado fue la reserva grasa. Solamente en el 5% de los niños se corroboró alergia alimentaria.Conclusiones: Nuestro estudio confirma la necesidad de una correcta asesoría nutricional en aquellos pacientes que cuenten con dietas de eliminación, así como el sobrediagnóstico que existe de alergia alimentaria.
Abstract:Background: The backbone of food allergy treatment is the restriction of causative foods. These interventions have shown that children who restrict the consumption of basic foods have a higher risk of malnutrition.The aim of the study was to identify the nutritional status of patients with elimination diet, characterizing their anthropometric indexes and identifying the percentage of patients in the group with true food allergies.Methods: A cross-sectional study was carried out from January to October 2014 at the Hospital Infantil de Mexico Federico Gomez. Patients 1 to 11 years of age with a history of elimination of at least one of five foods (eggs, milk, wheat, corn, soybeans) for a minimum of 6 months were included. Full nutritional assessment was performed by comparing the anthropometric indexes to z score for age. Data analysis used descriptive statistics. Kruskal-Wallis and Spearman correlation were performed.Results: The most frequent eliminated foods were milk, soy, eggs, corn, and wheat. Comparing the number of foods eliminated with different anthropometric indexes, with a greater amount of eliminated food, the z-score of weight/age (W/A), height/age (H/A) and weight/height (W/H) were lower and the most affected index was fat reserve. Only in 5% of children was food allergy confirmed.Conclusions The study confirms the need for nutrition counseling for patients who have elimination diets and overdiagnosis of food allergy.

ABSTRACT
OBJECTIVE: To evaluate factors associated with mortality and infections in patients with systemic lupus erythematosus (SLE) and diffuse alveolar hemorrhage (DAH). METHODS: A retrospective chart review was carried out for medical admissions of patients with a diagnosis of SLE and DAH in 9 hospitals. Clinical and laboratory data were recorded for each patient at DAH diagnosis. RESULTS: We included 57 episodes of DAH of 50 patients (7 recurrences), 49 women (86%), 14 juvenile SLE (24.6%); 24 had died (42.1%). In the chart review we detected infection in 22 episodes (38.6%): 8 invasive fungal infections, 16 bacterial infections, and 2 patients had both types. In the bivariate analysis, factors associated with mortality were high Acute Physiology and Chronic Health Evaluation II scores, requirement of mechanical ventilation (OR 15.0, 95% CI 1.9 to 662.2), infections (fungal or bacterial; OR 3.2, CI 0.9 to 11.1), renal failure (OR 4.9, CI 1.4 to 18.0), and thrombocytopenia (OR 4.3, CI 1.2 to 15.6). We found similar mortality between children and adults. Infections were associated with treatment for SLE, requirement of mechanical ventilation, hypocomplementemia, and high levels of C-reactive protein. CONCLUSION: Infection is a frequent finding in patients with DAH and SLE; we found similar mortality between adult SLE and juvenile SLE. Factors that we describe associated with infections may influence the therapeutic selection for these patients.
