Objective:Eosinophilic esophagitis (EoE) is associated with significant morbidity in children. Strategies for optimizing its outcomes are hence essential. We aimed to review the strategies for medical management of EoE in children.Methods:We conducted a systematic review of randomized controlled trials (RCTs) of medical interventions in children with EoE, using the Cochrane methodology. Databases including PubMed, EMBASE, CINAHL, Cochrane Central Library, and Google scholar were searched up to March 2016. Primary outcomes included histological (peak eosinophil count) and symptomatic remission. Secondary outcomes were improvement in endoscopic and other histological parameters and adverse effects.Results:A total of 5 RCTs (N=448) with low to unclear risk of bias were included. The interventions included topical oral steroids, swallowed enteral steroids and anti- interleukin (IL)5 agent. Pooling of data from all trials was not possible owing to significant heterogeneity in interventions. Meta-analysis of data (N=141) from 3 RCTs (oral viscous budesonide: 2, fluticasone: 1) showed significant histological remission in the intervention versus control group participants (risk difference: 10.32 [95% confidence interval: 3.04, 35.03]; P=0.0002), level of evidencelow. Compared with anti-IL5 agent, the trials assessing steroids reported high rates of clinical remission. Clinical remission did not correlate with histological improvement in any trial. Except for systemic corticosteroids, there were no significant adverse effects related to other interventions.Conclusions:Limited low-quality evidence exists on the effects of various interventions in children with EoE. The beneficial effects of swallowed steroid need to be confirmed in large well-designed RCTs.

Objective(s): Helicobacter pylori are among most common human pathogens affecting at least half of the world's population. Mobility is one of the important primary factors in bacterial colonization and invasion. The purpose of this research is cloning, expression, and purification of FlaA protein specific epitopes in order to evaluate their antigenicity and immunogenicity. Materials and Methods: The antigenic region of the flaA gene was bioinformatically predicted using Epitope mapping software's and the predicted epitopes were expressed in a prokaryotic expression vector. The antigen was injected into the animal model (mice BALB/c) and some indicators including IgG1, IgG2a, IgA, IFN-gamma, and IL 5 were measured. Results: The immunogenicity studies in animal models by measuring serum antibodies (IgG1, IgG2a, and IgA) and cytokines (IFN-gamma and IL5) revealed that the rFlaA induces a proper immune response in animal models. Conclusion: The recombinant FlaA protein is antigenic and immunogenic. Therefore, it might be used in order to design of specific diagnostic kits and recombinant vaccines against H. pylori.
