Patients with extensive disease started taking 5 mg/kg of IFX were more likely to require dose escalation compared to those with limited or moderate disease. All of the patients with moderate and extensive disease started taking 10 mg/kg of IFX remained on this dose. These results suggest that patients with more extensive disease may benefit from higher initial IFX dosing as it relates to durability of the treatment.
Biliary atresia is a common cause of cholestasis in infants and is a time-sensitive diagnosis. A survey was distributed to pediatric primary care providers in order to assess variations in diagnosis and management of cholestasis. Participants were identified from physician parent groups on social media and regional pediatric residency programs. Information on knowledge and interpretation of screening tests, past experience/behavior, confidence, and comfort level managing cholestasis, as well as demographic information was collected. Out of 116 eligible respondents, 94.8% were confident in diagnosing hyperbilirubinemia but only 10.3% knew the biochemical definition of direct hyperbilirubinemia. Of the 56% of providers who had some knowledge of the guidelines, 18.5% stated the guidelines changed the way they evaluate cholestasis. These results demonstrate a gap in knowledge of diagnosing and evaluating cholestasis, which could provide the framework for standardized screening, leading to earlier identification of biliary atresia.
The pathogenesis of eosinophilic esophagitis (EoE) involves Th2-mediated eosinophil recruitment and degranulation into the esophagus. However, measuring serum Th2 cytokines, eosinophils, and eosinophil-derived products does not reliably distinguish EoE from control populations. Non-invasive methods to diagnose EoE are lacking. We evaluated the diagnostic value of a novel candidate biomarker of EoE: 15(S)-hydroxyeicosatetraenoic acid (HETE). We used immunoassay to measure 15(S)-HETE and cytokine profiles in patients undergoing endoscopy with known or suspected EoE. 31 subjects were enrolled, 16 with EoE, and 15 with an alternate diagnosis. 15(S)-HETE was elevated in the EoE group compared to non-EoE group. The sensitivity and specificity of 15(S)-HETE to be used as a non-invasive marker is 50% and 80%, respectively. 15(S)-HETE may aid in the diagnosis of EoE.
Introduction. Gastrointestinal (GI) symptoms commonly occur during diabetic ketoacidosis (DKA) and typically resolve with treatment. However, GI complications can persist after DKA resolves. The incidence of upper GI bleeding during DKA in adults has been described, with erosive esophagitis one of the most common lesions. The incidence of GI bleeding or erosive esophagitis in children with DKA has not been previously reported. We performed a retrospective chart review of DKA admissions in children 0 to <18 years with type 1 diabetes mellitus (T1DM) at a pediatric hospital between January 2009 and July 2016. Among 395 episodes of DKA over 7.5 years, erosive esophagitis occurred during two DKA admissions (0.5%) and there were no episodes of GI bleeding. Case presentations. Both episodes of erosive esophagitis occurred in adolescent males with known T1DM who presented with severe DKA. Both developed odynophagia after resolution of DKA and were readmitted for DKA recurrence. Upper endoscopy for both patients showed erosive esophagitis. Biopsies were negative for infection, though candida was found during one patient’s endoscopy. Both had resolution of their esophagitis symptoms with medication management; neither has had recurrence. Conclusion. Erosive esophagitis, a rare complication of pediatric DKA, can manifest with odynophagia or substernal chest pain. This complication can lead to DKA recurrence, likely due to increased insulin resistance from inflammation and pain and from reduced oral intake and insulin administration. Patients with odynophagia associated with DKA should be monitored closely to allow timely evaluation and treatment of esophagitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
