Abstract
Long COVID is estimated to have affected 6.9 % of US adults, 17.8 million people in the US alone, as of early 2023. While SARS-CoV-2 is primarily considered a respiratory virus, gastrointestinal (GI) symptoms are also frequent in patients with coronavirus disease 2019 (COVID-19) and in patients with Long COVID. The risk of developing GI symptoms is increased with increasing severity of COVID-19, the presence of GI symptoms in the acute infection, and psychological distress both before and after COVID-19. Persistence of the virus in the GI tract, ensuing inflammation, and alteration of the microbiome are all likely mediators of the effects of SARS Co-V-2 virus on the gut. These factors may all increase intestinal permeability and systemic inflammation. GI inflammation and dysbiosis can change the absorption and metabolism of tryptophan, an important neurotransmitter. Long COVID GI symptoms resemble a Disorder of Gut Brain Interaction (DGBI) such as post infection Irritable Bowel Syndrome (IBS). Current standards of treatment for IBS can guide our treatment of Long COVID patients. Dysautonomia, a frequent Long COVID condition affecting the autonomic nervous system, can also affect the GI tract, and must be considered in Long COVID patients with GI symptoms. Long COVID symptoms fall within the broader category of Infection Associated Chronic Conditions (IACCs). Research into the GI symptoms of Long COVID may further our understanding of other post infection chronic GI conditions, and elucidate the roles of therapeutic options including antivirals, probiotics, neuromodulators, and treatments of dysautonomia.
期刊介绍:
Life Sciences is an international journal publishing articles that emphasize the molecular, cellular, and functional basis of therapy. The journal emphasizes the understanding of mechanism that is relevant to all aspects of human disease and translation to patients. All articles are rigorously reviewed.
The Journal favors publication of full-length papers where modern scientific technologies are used to explain molecular, cellular and physiological mechanisms. Articles that merely report observations are rarely accepted. Recommendations from the Declaration of Helsinki or NIH guidelines for care and use of laboratory animals must be adhered to. Articles should be written at a level accessible to readers who are non-specialists in the topic of the article themselves, but who are interested in the research. The Journal welcomes reviews on topics of wide interest to investigators in the life sciences. We particularly encourage submission of brief, focused reviews containing high-quality artwork and require the use of mechanistic summary diagrams.
