SUMMARY Although the existence of national data on BBIs provides much-needed information on the epidemiology of these serious injuries, there are no prospective studies available to guide management decisions. As a result, treatment recommendations are primarily based on expert opinion from related clinical experience. The single-center experience of the serious esophageal BBI cases presented in this article is the largest published outside of the compiled national data and offers important lessons for the management of future cases. Additional study is needed to better define the role of acid blockade, endoscopy, and MRI in the postremoval management of these cases and determine optimal timing for initiation of enteral feeding. Advocacy efforts are ongoing and vital in order to minimize the occurrence of these potentially fatal injuries.
In summary, the endocannabinoid system is induced in murine ileitis but is downregulated in chronic murine and human intestinal inflammation, and CB2R activation attenuates murine ileitis, establishing an anti-inflammatory role of the endocannabinoid system.
Background Inflammatory bowel disease is a lifelong disease of the gastrointestinal tract whose annual incidence and prevalence is on the rise. Current immunosuppressive therapies available for treatment of inflammatory bowel disease offer limited benefits and lose effectiveness, exposing a significant need for the development of novel therapies. In the clinical setting, cannabis has been shown to provide patients with inflammatory bowel disease symptomatic relief, although the underlying mechanisms of their anti-inflammatory effects remains unclear. Methods This review reflects our current understanding of how targeting the endocannabinoid system, including cannabinoid receptors 1 and 2, endogenous cannabinoids anandamide and 2-arachidonoylglycerol, atypical cannabinoids, and degrading enzymes including fatty acid amide hydrolase and monoacylglycerol lipase, impacts murine colitis. In addition, the impact of cannabinoids on the human immune system is summarized. Results Cannabinoid receptors 1 and 2, endogenous cannabinoids, and atypical cannabinoids are upregulated in inflammation, and their presence and stimulation attenuates murine colitis, while cannabinoid receptor antagonism and cannabinoid receptor deficient models reverse these anti-inflammatory effects. In addition, inhibition of endocannabinoid degradation via monoacylglycerol lipase and fatty acid amide hydrolase blockade can also attenuate colitis development, and is closely linked to cannabinoid receptor expression. Conclusions While manipulation of the endocannabinoid system in murine colitis has proven to be largely beneficial in attenuating inflammation, there is a paucity of human study data. Further research is essential to clearly elucidate the specific mechanisms driving this anti-inflammatory effect for the development of therapeutics to target inflammatory disease such as inflammatory bowel disease.
The trend towards decriminalization of cannabis (marijuana) continues sweeping across the United States. Colorado has been a leader of legalization of medical and recreational cannabis use. The growing public interest in the medicinal properties of cannabis and its use by patients with a variety of illnesses including inflammatory bowel disease (IBD) makes it important for pediatric gastroenterologists to understand this movement and its potential impact on patients. This article describes the path to legalization and “medicalization” of cannabis in Colorado as well as the public perception of safety despite the known adverse health effects of use. We delineate the mammalian endocannabinoid system and our experience of caring for children and adolescents with IBD in an environment of increasing awareness and acceptance of its use. We then summarize the rationale for considering that cannabis may have beneficial as well as harmful effects for IBD patients. Finally, we highlight the challenges federal laws impose on conducting research on cannabis in IBD. The intent of this article is to inform health care providers about the issues around cannabis use and research in adolescents and young adults with IBD.
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.
