Critical review of ISAAC results for atopic dermatitis in tropical cities
Abstract
In different epidemiological medical tests -specifically the ones tested in tropical regions- a substantial increase has been observed in the prevalence of atopic dermatitis. ISAAC is the largest international test to analyze dermatitis epidemiology, which tested the prevalence of the most prevalence of the most common childhood atopic diseases in almost 200 points in more than 50 countries around the world. According to that test, the prevalence of dermatitis in tropical countries, especially in those from Latin America, was higher in comparison with other regions with a mode of 15%. That percentage among those populations using the same survey suggests that some genetic and environmental factors have an important effect on the development of dermatitis. However, considering that the surveys were completed by participants, it is possible that there was a misidentification of the disease and a tilt made from the patient, therefore comparative tests with cohort studies of the region are needed in order to determine if they are clinically relevant or not. In this article, we compare the prevalence of dermatitis reported by the ISSAC in tropical countries and some studies using other commonly diagnostic methods tested in the region.
En diversos análisis epidemiológicos —especialmente en aquellos realizados en regiones del trópico— se ha observado notable aumento en la prevalencia de la dermatitis atópica. El estudio internacional más extendido que evalúa la epidemiología de la dermatitis es el estudio ISAAC, que examinó la prevalencia de las enfermedades atópicas más prevalentes en la infancia en casi 200 centros en más de 50 países del mundo. De acuerdo con este estudio, la prevalencia de dermatitis en países tropicales, especialmente de América Latina, fue mayor en comparación con otras regiones, con una moda de 15 %. Esta mayor prevalencia entre poblaciones que utilizan la misma encuesta sugiere que algunos factores genéticos y ambientales tienen un efecto importante en el desarrollo de la dermatitis. Sin embargo, teniendo en cuenta que las encuestas fueron completadas por los participantes, es posible que existiera sesgo e identificación errónea de la enfermedad por parte del individuo, por lo que es necesario realizar estudios comparativos con los estudios de cohorte de la región para determinar si son clínicamente relevantes o no. En este artículo comparamos la prevalencia de dermatitis reportada por el estudio ISAAC en países tropicales y algunos estudios en la región que utilizaron otros métodos diagnósticos.
