Objectives The purpose of this study was to assess the epidemiological, clinical, endoscopic, and pathohistological characteristics of pediatric eosinophilic esophagitis (EoE) in Serbia. found in only 20% of the patients. Since 2016, the number of biopsy samples has increased, but the sampling rate of lamina propria is still low ( 50%). The correlation between the number of biopsies and lamina propria acquisition was strong ( 0.05). In 2 immunocompetent adolescents, EoE was diagnosed after successful treatment of infectious esophagitis. Conclusions An increase in the incidence of EoE in Serbian children is obvious. The biopsy rate in children with nonspecific and reflux symptoms should be increased, as well as the number of biopsy samples for the detection of subepithelial fibrosis. In immunocompetent children with infectious esophagitis, EoE should be suspected and endoscopy may be recommended after successful treatment of illness. test. Nonparametric numerical data were compared using the Mann-Whitney U test. Categorical variables were compared using the 2 test and Fisher’s exact probability. Correlation was performed by Spearman correlation. Statistical significance was founded at = 1.691, 0.05). An increase was obvious in the number of newly diagnosed individuals with EoE in 2016 and 2017 relative to earlier years as demonstrated in Figure ?Number2.2. The number of newly diagnosed EoE individuals per year correlated strongly with the esophageal biopsy rate ( 0.05) and the number of biopsies per examination ( 0.001). In Serbia, about 30% of children diagnosed with pediatric gastrointestinal diseases are referred to University Children’s Hospital. Therefore, the estimated median incidence rate of EoE in Serbian children from 2010C2017 was 0.85 per 100,000 children per year. The highest incidence rates were 3.17 per 100,000 children in 2017 Olprinone Hydrochloride FSCN1 and 1.95 Olprinone Hydrochloride per 100,000 children in 2016. The estimated prevalence of pediatric EoE in Serbia was 6.83 per 100,000 children. Clinical endoscopy and display results in various age ranges are provided in Desk ?Desk2.2. In 6 (17.1%) sufferers, meals impaction was the initial symptom. The youngest patient was a 3-year-old girl with reflux food and symptoms refusal. Reflux symptoms had been more frequent in young ladies (55.6%) than in children (11.5%) (Fisher’s check, = 0.015).

This difference had not been significant ( 0 statistically.05). The median period from the incident of the initial symptoms to medical diagnosis was much longer from 2010 to 2015 (4.5 15.5 months) than from 2016 to 2017 (3.0 23.9 months), without factor ( 0.05). There have been no significant distinctions in Olprinone Hydrochloride age group (Desk ?(Desk2)2) and gender concerning endoscopic results ( 0.05). Inflammatory adjustments (longitudinal furrowing, white plaques) had been within 74.3% of children, fibrostenotic changes (bands, strictures) in 62.9% of children, and both in 48.6% of children. There have been no significant distinctions in sex, age ranges, and kind of symptoms ( 0.05). The real amount of endoscopic signs in each patient was analyzed. In each individual, 4 endoscopic signals were examined: longitudinal furrowing, bands, white plaques, and esophageal strictures. Mucosal edema, often present although, was not defined generally in most endoscopic reviews and, therefore, had not been analyzed. Away from 35 sufferers, 4 (11.4%) kids had regular endoscopic findings. An individual endoscopic indication was within 9 (25.7%) kids, 2 signals in 16 (45.7%) kids, and 3 signals in 3 (17.1%) kids. Seven (20%) kids had pathological.
