Background Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe adverse drug reaction including integumentary and internal organs. An extensive literature review of DRESS in the pediatric population has not been performed. Methods A literature search was performed to find reports of pediatric DRESS published between 1997 and March 2019. If not already included, each case was scored based on RegiSCAR criteria. Only “probable” or “definite” cases of DRESS were included in the analysis, totaling 130 cases. Results In the pediatric population, the average age of diagnosis for DRESS was 8.7 years old. The most common causative drugs include antiepileptics (50%) and antibiotics (30.8%). Time from drug exposure to DRESS presentation averaged 23.8 days. Common clinical symptoms include rash (99.2%) (typically morbilliform (89.2%)), fever (96.2%), eosinophilia (90%), and lymphadenopathy (74.6%). Human herpesvirus‐6 reactivation was observed in 16.1% of cases. The most commonly affected internal organ was the liver (80%), followed by the spleen (21.5%) and kidney (15.4%). Management strategies involved, either alone or in combination, included corticosteroids (intravenous 60.8% and oral 41.5%), intravenous immunoglobulins (12.3%), plasmapheresis (2.3%), and ganciclovir (1.5%). Long‐term sequelae occurred in 10.8% of patients, most commonly hypothyroidism (3.8%), liver failure (3.1%), and diabetes (2.3%). The mortality rate was 5.4%. Conclusion This literature review highlights the presentation and course of pediatric DRESS. Morbilliform eruption, fever, and eosinophilia appear to be clinical hallmarks of pediatric DRESS. Common causative agents, specifically carbamazepine, are comparable to the adult population. Furthermore, the mortality rate from DRESS is significant and is similar between pediatric and adult patients.
Atopic dermatitis (AD) is a chronic inflammatory skin condition that can have tremendous impact on quality of life for affected children and adults. First-line therapy for acute management of AD includes topical therapies such as corticosteroids, calcineurin inhibitors, and, more recently, the phosphodiesterase inhibitor crisaborole. Topical agents have remained the mainstay therapy for decades; however, there has been a longstanding need for topical therapies with high efficacy and low risk of adverse effects with long-term use. Given the ongoing advances in understanding the pathogenesis of AD, there are novel targets for pharmacological intervention. We are now in an unprecedented time with more than 40 topical treatments in the pipeline for AD in addition to many developments and treatments on the horizon. This review summarizes selected therapeutic topical agents in later phases of development that target various aspects in the pathogenesis of AD such as Janus kinase inhibition (ruxolitinib and delgocitinib), phosphodiesterase-4 inhibition (roflumilast and difamilast), aryl hydrocarbon modulation (tapinarof), and modulation of the microbiome. We also review novel targeted therapies that are in early phase clinical trials, including AMTX-100, BEN-2293, and PRN473. Preliminary findings on efficacy and tolerability of most of these agents are promising, but further studies are warranted to evaluate the long-term safety and efficacy of these novel agents against the current standard of care.
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.
