[New recommendations on the diagnosis and treatment of eosinophilic esophagitis in children and adults].

Besides gastro-esophageal reflux, eosinophilic esophagitis (EoE), is the most frequently diagnosed chronic inflammatory disease both in children and adults. Clinical symptoms depend on the age of the patient and the time of the disease. In infants and younger children feeding disturbances, physical development retardation, vomiting and abdominal pain are most frequent. Difficulty in solid food swallowing, food impaction in the esophagus and chest pain are the most frequent symptoms in older children and adults. In the endoscopic study of the esophagus, esophagitis, rings and esophageal stricture may be visible. Traits of chronic inflammation and eosinophilic infiltration are present in histologic examination. In the year 2017, an international experts' working group, headed by A.J. Lucendo, under the auspices of UEG - United European Gastroenterology, ESPGHAN - European Society of Pediatric Gastroenterology, Hepatology and Nutrition, EAACI - European Academy of Allergy and Clinical Immunology, EUREOS - European Society of Eosinophilic Oesophagitis, elaborated diagnostic and therapeutic recommendations for eosinophilic esophagitis using the GRADE method (Grading of Recommendations Assessment, Development and Evaluation). The international experts' group included gastroenterologists, aerologists, pediatricians, laryngologists, pathologists and epidemiologists. The wide spectrum of specialists in various fields made it possible to consider various aspects of the disease in their recommendations.
