Eosinophilic Esophagitis: Update on Diagnosis and Treatment in Pediatric Patients.
Rossetti, D, Isoldi, S, Oliva, S
Paediatric drugs. 2020;(4):343-356
Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated inflammatory disorder characterized by symptomatic esophageal dysfunction and an eosinophil-predominant inflammation of the esophagus. EoE arises from interaction between genetic and environmental factors. In pediatric patients, clinical manifestations vary depending on age, from a gastroesophageal reflux disease (GERD)-like condition to severe dysphagic symptoms. Upper endoscopy is considered the gold standard for diagnosis and monitoring of EoE; however, significant efforts are underway to identify noninvasive diagnostic tools and biomarkers to avoid repetitive invasive procedures. Therapeutic first-line options currently available for EoE are elimination diets, proton pump inhibitors (PPIs), and steroids. The aim of treatment is to improve clinical symptoms while obtaining mucosal healing and avoiding long-term complications. Dietary treatment options comprise different empiric diets or an exclusively amino acid formula. Despite the efficacy of diets, compliance is often challenging. PPIs and topical steroids represent the main pharmacological options for EoE, and both can induce and maintain remission. Topical steroids have been reported as more effective, but data on long-term safety remain insufficient for both these and PPIs. Endoscopic dilations are currently reserved for severe untreated fibrostenotic disease unresponsive to medical therapies. Several biologic agents are available but not yet approved for EoE.

Abstract
Laparoscopic floppy Nissen fundoplication (LFNF) is an effective treatment for gastroesophageal reflux disease. The duration of convalescence, after noncomplicated LFNF, may depend on several factors of which pain, fatigue and sociocultural factors are the most important. Nausea and vomiting occur mainly on the day of operation. Glucocorticoids are well known for their analgesic, anti-inflammatory, immune-modulating and antiemetic effects. We therefore undertook the present study to investigate whether preoperative dexamethasone could improve surgical outcome in patients undergoing uncomplicated laparoscopic floppy Nissen fundoplication. From March 2005 to April 2008, 82 patients were randomized to receive dexamethasone (8 mg) intravenously, 90 min before skin incision or saline (placebo). Patients received a similar standardized anesthetic, surgical and multimodal analgesic treatment. The primary end points were pain and fatigue. Preoperatively and at several times during the first 24 postoperative hours, we measured C-reactive protein (CRP), interleukin-6 and 1 (IL-6, IL-1), pain scores and nausea, and the number of vomiting episodes were registered. Dexamethasone significantly reduced postoperative levels of CRP (p = 0.01), IL-6 and IL-1 (p < 0.05), fatigue (p = 0.01) and overall pain during the first 24 postoperative hours (p < 0.05) and the total requirement of analgesic (ketorolac) (p < 0.05). Dexamethasone also reduced nausea and vomiting on the day of operation (p < 0.05). Preoperative dexamethasone (8 mg) reduced pain, fatigue, nausea and vomiting in patients undergoing uncomplicated LNF when compared with placebo.

Tolerance of probiotics and prebiotics.
Marteau, P, Seksik, P
Journal of clinical gastroenterology. 2004;(6 Suppl):S67-9
Abstract
The clinical efficacy of probiotics and prebiotics has been proved in several clinical settings. The authors review their proved or potential side effects. Probiotics as living microorganisms may theoretically be responsible for 4 types of side effects in susceptible individuals: infections, deleterious metabolic activities, excessive immune stimulation, and gene transfer. Very few cases of infection have been observed. These occurred mainly in very sick patients who received probiotic drugs because of severe medical conditions. Prebiotics exert an osmotic effect in the intestinal lumen and are fermented in the colon. They may induce gaseousness and bloating. Abdominal pain and diarrhea only occur with large doses. An increase in gastroesophageal reflux has recently been associated with large daily doses. Tolerance depends on the dose and individual sensitivity factors (probably the presence of irritable bowel syndrome or gastroesophageal reflux), and may be an adaptation to chronic consumption.
