RESUMEN
BACKGROUND AND AIM: The burden of childhood asthma and its risk factors is an important but neglected public health challenge in Latin America. We investigated the association between allergic symptoms and dietary intake in children from this region. METHODS: As part of the International Study of Asthma and Allergies in Childhood (ISAAC) Phase III, questionnaire collected dietary intake was investigated in relation to risk of parental/child reported current wheeze (primary outcome) and rhino-conjunctivitis and eczema. Per-country adjusted logistic regressions were performed, and combined effect sizes were calculated with meta-analyses. RESULTS: 143,967 children from 11 countries had complete data. In children aged 6-7 years, current wheeze was negatively associated with higher fruit intake (adjusted odds ratio [aOR] 0.65; 95% CI 0.74, 0.97). Current rhino-conjunctivitis and eczema were statistically negatively associated with fruit intake (aOR 0.72; 95% CI 0.64, 0.82; and OR 0.64, 95% CI 0.56, 0.74, respectively). Vegetable intake was negatively associated with risk of symptoms in younger children, but these associations were attenuated in the 13-14 years old group. Fastfood/burger intake was positively associated with all three outcomes in the older children. CONCLUSION: A higher intake of fruits and vegetables was associated with a lower prevalence of allergic symptoms in Latin American children. Conversely, intake of fastfood was positively associated with a higher prevalence of wheeze in adolescents. Improved dietary habits in children might help reduce the epidemic of allergic symptoms in Latin America. Food interventions in asthmatic children are needed to evaluate the possible public health impact of a better diet on respiratory health.

Allergies comprise a set of highly prevalent diseases. When allergic processes are not controlled, they can endanger patients' health and lives, and have an important economic and social impact. The aim of this paper is to present a practical consensus of the scientific evidence on the use of immunotherapy in allergic diseases. A collaborative review made by various institutes and universities in Colombia was carried out upon request of the Asociación Colombiana de Alergia, Asma e Imunología, led by general practitioners, allergists, immunologists, internists and paediatricians with experience in the field of allergies. As a result, based on current national and international scientific evidence, we describe in detail what immunotherapy is about, its indications, contraindications and its economic and health benefits. Conclusions show immunotherapy as a clinically effective and safe treatment, which can substantially reduce the cost of the overall treatment of allergic patients.

Las alergias constituyen un conjunto de enfermedades de gran prevalencia. Cuando los procesos alérgicos no se controlan, pueden poner en peligro la salud e, incluso, la vida de los pacientes y, además, su efecto económico y social es considerable. El objetivo de esta revisión es presentar un consenso práctico de la información científica disponible sobre el empleo de la inmunoterapia en las enfermedades alérgicas con la colaboración de varios institutos y universidades de Colombia, por solicitud de la Asociación Colombiana de Alergia, Asma e Inmunología. La revisión incluyó aspectos prácticos presentados desde el punto de vista de médicos generales, alergólogos, inmunólogos, internistas y pediatras con experiencia en el campo de las alergias. Con base en la evidencia científica actual a nivel nacional e internacional, se describió de forma detallada en qué consiste la inmunoterapia, sus indicaciones, contraindicaciones y sus beneficios para la salud, así como en el ámbito socioeconómico. Se concluyó que la inmunoterapia es efectiva y segura, y que, además, puede reducir sustancialmente el costo del tratamiento global de los pacientes alérgicos.

BACKGROUND: Diet might influence the risk of allergic diseases. Evidence from developing countries with high prevalence of childhood asthma is scant. METHODS: Information on wheeze, rhinitis, and eczema was collected from 3209 children aged 6-7 years in 2005, who were taking part in the International Study on Asthma and Allergy in Children (ISAAC) in Colombia. Intake frequency of twelve food groups was assessed. Associations between each food group and current wheeze, rhino-conjunctivitis, and eczema were investigated with multiple logistic regressions, adjusting for potential confounders. Simes' procedure was used to test for multiple comparisons. RESULTS: 14.9% of children reported wheeze in the last 12 months, 16% rhino-conjunctivitis, and 22% eczema. Eczema was negatively associated with consumption of fresh fruits and pulses three or more times per week (adjusted Odds ratio (aOR): 0.64; 95% Confidence Interval (CI): 0.49 to 0.83; p value = 0.004; and aOR: 0.62, 95% CI: 0.47 to 0.80; p value < 0.001, respectively). Current wheeze was negatively associated with intake of potatoes (aOR: 0.44, 95% CI: 0.31 to 0.62, p value = 0.005), whilst this outcome was positively associated with consumption of fast food (aOR: 1.76, 95% CI: 1.32 to 2.35, p value = 0.001). These associations remained statistically significant after controlling for multiple comparisons. CONCLUSIONS: A traditional diet might have a protective effect against eczema and wheeze in Colombian children, whilst intake of fast foods increases this risk.

Presentamos los casos de siete pacientes (5 mujeres y 2 hombres) con edades comprendidas entre los 4 y 38 anos e historia de infecciones recurrentes por Staphylococcus aureus, y elevacion de los niveles sericos totales de inmunoglobulina E (IgE). El cuadro clinico se caracterizo por la presencia de abscesos subcutaneos multiples cuyas localizaciones mas frecuentes incluian las axilas (6/7) y las extremidades (3/7). Otras localizaciones menos frecuentes fueron los gluteos, el cuero cabelludo, las glandulas mamarias, la vulva y el perine. En cinco de siete pacientes la enfermedad se inicio antes de los 3 anos de edad. Dos de estos pacientes desarrollaron asma bronquial y otros 3 presentaron severos cuadros de eczema cronico. Las biopsias de piel practicadas en estos ultimos pacientes fueron compatibles con el diagnostico patologico de dermatitis cronica inespecifica. Todos los pacientes presentaron anemia microcitica hipocromica y marcada eosinofilia en sangre periferica. Cuatro pacientes presentaron elevaciones en los niveles sericos de alfa-2-globulina e inmunoglobulina G (IgG). Mientras que los estudios de migracion celular fueron normales en todos los pacientes, dos de ellos presentaron deterioro en el mecanismo oxidativo de la fagocitosis
