PIERRE, Reinaldo et al. Multicenter study on the epidemiology of pediatric eosinophilic esophagitis in latinamerica. Gen [online]. 2016, vol.70, n.4, pp.125-130. ISSN 2477-975X.

Aims: To evaluate epidemiological features of pediatric patients with eosinophilic esophagitis in Latinamerica and therapeutical options indicated by pediatric gastroenterologists in our continent. Patients and methods: multicenter, observational, transversal study. 36 Centers of Pediatric Gastroenterology and Endoscopy from 10 latinamerican countries participated giving clinical and sociodemographic information about pediatric patients with EoE diagnosed and treated during the last two years (study period). Results: 372 cases of pediatric EoE were evaluated during period 2014-2016 (108 cases were evaluated during trimester April-June 2016). 46,72% of cases were school age children, with dysphagia been the main clinical symptom in 71,8% of patients. 87,2% of patients received diet as a main indication of treatment, 55,3% received swallowed steroids (12,8% as monotherapy) and 6% were treated with montelukast among others. There were no reports of patients under treatment with biological drugs. Conclusions: epidemiological features of our study group suggest a higher prevalence of pediatric EoE in male school age children and adolescents. Most frecuent clinical symptoms are dysphagia, vomiting and gastroesophageal reflux symptoms. Treatment is based mainly on diet and swallowed steroids. A continental prevalence study is necessary to evaluate the behavior of the disease in different regions of Latinamerica.
