The Interrelationships between Intestinal Permeability and Phlegm Syndrome and Therapeutic Potential of Some Medicinal Herbs.
Park, J, Choi, TJ, Kang, KS, Choi, SH
Biomolecules. 2021;(2)
Abstract
The gastrointestinal (GI) tract has an intriguing and critical role beyond digestion in both modern and complementary and alternative medicine (CAM), as demonstrated by its link with the immune system. In this review, we attempted to explore the interrelationships between increased GI permeability and phlegm, an important pathological factor in CAM, syndrome, and therapeutic herbs for two disorders. The leaky gut and phlegm syndromes look considerably similar with respect to related symptoms, diseases, and suitable herbal treatment agents, including phytochemicals even though limitations to compare exist. Phlegm may be spread throughout the body along with other pathogens via the disruption of the GI barrier to cause several diseases sharing some parts of symptoms, diseases, and mechanisms with leaky gut syndrome. Both syndromes are related to inflammation and gut microbiota compositions. Well-designed future research should be conducted to verify the interrelationships for evidence based integrative medicine to contribute to the promotion of public health. In addition, systems biology approaches should be adopted to explore the complex synergistic effects of herbal medicine and phytochemicals on conditions associated with phlegm and leaky gut syndromes.

The Role of the Gluten-Free Diet in the Management of Seronegative Enteropathy.
Szaflarska-Popławska, A
Nutrients. 2021;(11)
Abstract
The differential diagnosis and treatment of seronegative enteropathy, also termed seronegative villous atrophy (SNVA), is a clinical challenge. Although seronegative coeliac disease (CD) is a frequent cause of SNVA, the aetiology can include immune-mediated, inflammatory, infectious, and drug-related forms. As a misdiagnosis of SNVA can result in patients being unnecessarily placed on a lifelong strict gluten-free diet or even given incorrect immunosuppressive therapy, the aim of this paper is to provide an evidence-based and practical approach for the workup and management of SNVA.

New insights in intestinal ischemia-reperfusion injury: implications for intestinal transplantation.
Lenaerts, K, Ceulemans, LJ, Hundscheid, IH, Grootjans, J, Dejong, CH, Olde Damink, SW
Current opinion in organ transplantation. 2013;(3):298-303
Abstract
PURPOSE OF REVIEW Ischemia-reperfusion injury is inevitable during intestinal transplantation and can negatively affect the transplant outcome. Here, an overview is provided of the recent advances in the pathophysiological mechanisms of intestinal ischemia-reperfusion injury and how this may impact graft survival. RECENT FINDINGS The intestine hosts a wide range of microorganisms and its mucosa is heavily populated by immune cells. Intestinal ischemia-reperfusion results in the disruption of the epithelial lining, affecting also protective Paneth cells (antimicrobials) and goblet cells (mucus), and creates a more hostile intraluminal microenvironment. Consequently, both damage-associated molecular patterns as well as pathogen-associated molecular patterns are released from injured tissue and exogenous microorganisms, respectively. These 'danger' signals may synergistically activate the innate immune system. Exaggerated innate immune responses, involving neutrophils, mast cells, platelets, dendritic cells, as well as Toll-like receptors and complement proteins, may shape the adaptive T-cell response, thereby triggering the destructive alloimmune response toward the graft and resulting in transplant rejection. SUMMARY Innate immune activation as a consequence of ischemia-reperfusion injury may compromise engraftment of the intestine. More dedicated research is required to further establish this concept in man and to design more effective therapeutic strategies to better tolerize intestinal grafts.

Gut flora in health and disease.
Guarner, F, Malagelada, JR
Lancet (London, England). 2003;(9356):512-9
Abstract
The human gut is the natural habitat for a large and dynamic bacterial community, but a substantial part of these bacterial populations are still to be described. However, the relevance and effect of resident bacteria on a host's physiology and pathology has been well documented. Major functions of the gut microflora include metabolic activities that result in salvage of energy and absorbable nutrients, important trophic effects on intestinal epithelia and on immune structure and function, and protection of the colonised host against invasion by alien microbes. Gut flora might also be an essential factor in certain pathological disorders, including multisystem organ failure, colon cancer, and inflammatory bowel diseases. Nevertheless, bacteria are also useful in promotion of human health. Probiotics and prebiotics are known to have a role in prevention or treatment of some diseases.

Clinical aspects of small-bowel transplantation.
Veenendaal, RA, Ringers, J, Baranski, A, van Hoek, B, Lamers, CB
Scandinavian journal of gastroenterology. Supplement. 2000;(232):65-8
Abstract
AIM: To update clinical aspects of small-bowel transplantation. METHODS Critical review of the literature. RESULTS The two major functions of the small bowel are absorption of food and protection of the body against ingested pathogens. The highly developed immune system of the bowel, necessary for the latter function, prevented successful small-bowel transplantation during the 1960s and 1970s by provoking early and severe rejection of the graft. The introduction of cyclosporin in the 1980s enabled small-bowel transplantation with a moderate success rate. Further improvement of immunosuppressive regimens, especially the introduction of tacrolimus and aggressive surveillance for and treatment of infections, has resulted in a slow but steady improvement of transplant results during the past decade. At this moment, however, long-term parenteral nutrition is still the first-line treatment of the short-bowel syndrome world-wide because of the excellent results with regard to patient survival. CONCLUSION Although results of small-bowel transplantation are steadily improving, especially due to better immunosuppressive regimens, long-term parenteral nutrition is still the first-line treatment of short-bowel syndrome.
