Membrane Phospholipids

Ulcerative colitis is a chronic inflammatory bowel disease with unclear etiology. An insufficient amount of data on the etiopathogenetic mechanisms of the disease creates opportunities to research them at the cellular level, including the membrane level. Since the functional state of the cytoplasmic membrane largely depends on protein-lipid interactions, we studied the effect of the proportional ratio of three proteins (glucose transporter, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and glutathione-S-transferase (GST)) on the level of phosphatidylethanolamine and phosphatidylcholine in the erythrocyte membrane of patients with ulcerative colitis during an acute attack. The study involved 51 patients with ulcerative colitis during the acute attack and 26 clinically healthy individuals. The groups are comparable by gender and age to study the proteins of the cytoplasmic membrane, Laemmli electrophoresis technique in polyacrylamide gel was used, followed by an assessment of the intensity of protein bands staining on electropherograms. Phospholipid fractions were obtained using thin-layer chromatography and their content was assessed using the Mathcad 2001 Professional system. Statistical processing was carried out by the program Statistica 10.0 for Windows. Changes of phosphatidylcholine and phosphatidylethanolcholine levels in patients and healthy individuals are not of the same type and are interrelated with changes in the proportion of membrane proteins of the glucose transporter, GAPDH and GST. The proportions of proteins that affect the level of phospholipids have calculated. In patients with ulcerative colitis, a decrease in the level of the studied membrane lipids have revealed in comparison with the clinically healthy group, in addition, an increase in the proportion of the glucose transporter and a decrease in the proportion of GST have noted. In addition, the relationship between an increase in the level of the cytoplasmic membrane phospholipids in ulcerative colitis and a change in the proportion of GAFDH in a smaller direction, which slows down the process of glucose oxidation, was determined. The obtained data confirm the strengthening of the processes of antioxidant protection and the increased need for energy supply of the cell membrane in patients with ulcerative colitis during an acute attack.

AbstractUlcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) induced by dysregulation of the immune response in the intestinal mucosa. Although the underlying mechanisms of UC development are not fully understood, disruption of gut microbiota, “dysbiosis”, is thought to lead to the development of IBD. Persimmon (Ebenaceae Diospyros kaki Thunb.)-derived tannin, which is a condensed polymeric tannin consisting of catechin groups, has antioxidant, anti-inflammatory, and antimicrobial activities. In this study, we assessed the effect of persimmon-derived tannin on a murine model of UC established by dextran sulfate sodium-induced colitis in female mice. Dietary supplementation of tannin significantly decreased disease activity and colon inflammation. A hydrolysate of tannin directly suppressed expression of inflammatory genes in macrophages in vitro. In faecal microbiota, the relative abundance of Bacteroides was increased significantly by tannin supplementation. Alpha-diversity indices in colitis-induced mice were significantly higher in the tannin diet group compared with the control diet group. Additionally, expansion of Enterobacteriaceae and Enterococcus, which is associated with disease progression of IBD, was remarkably suppressed in the tannin diet group. These results suggest that persimmon-derived tannin ameliorates colon inflammation in UC through alteration of the microbiota composition and immune response, which may be a promising candidate for IBD therapy.

Annotation. At the turn of the 21st century, chronic inflammatory bowel disease (CIBD) has become a global disease with accelerating morbidity in industrialized countries with a prevalence exceeding 0.3%. These data underscore the need for research into the prevention of inflammatory bowel disease and innovations in health care systems to manage this complex and costly disease. The information from a personal anamnesis of 40 women patients with ulcerative colitis (clinical group (main). In the second group (control), 30 practically healthy pregnant women with a physiological course of gestation were included, which did not have in their history of inflammatory intestinal diseases. Statistical processing of research results was performed using the software package Statistica 6.0. The arithmetic mean (M) and the standard deviation error (± m) (p<0.05) were determined, as well as the odds ratio (OR), confidence interval (CI) at p=95%. It was found that for women with ulcerative colitis is characterized by the presence of a history of obstetric pathology, such as: spontaneous miscarriage of OR 3.33, 95% CI [1.06-10.53], p=0.04 and blood secretions of OR 3.0, 95% CI [1.00-8.98], p=0.0496; among extragenital pathology in the anamnesis: children's infectious diseases of OR 4.85, 95% CI [1.25-18.85], p=0.02, chronic bronchitis of OR 7.54, 95% CI [1,56-36, 41], p=0.01, varicose veins OR 4.33, 95% CI [1.11-16.95], p=0.035, chronic gastritis OR 6.0, 95% CI [1,23-29, 31], p=0.03, anemia of OR 15.0, 95% CI [4.53-49.68], p<0.0001, allergy history of OR 6.65, 95% CI [1.73-25.60], p=0.006; among gynecological complications – premenstrual syndrome OR 6.0, 95% CI [1.55-23.15], p=0.009, algomenorrhea OR 8.14, 95% CI [2.12-31.24], p=0.002 , salpingo-oophoritis, OR 7.54, 95% CI [1.56-36.41], p=0.01. Because CIBD during pregnancy is associated with an increased risk of adverse effects on the mother and fetus, information on socio-anamnestic and clinical analysis of pregnant women with ulcerative colitis will be useful to health care providers in making decisions about CIBD during pregnancy.

Abstract Objectives The purpose of this paper is to summarize the current evidence on probiotics’ uses as an adjuvant for ulcerative colitis (UC) and provide an understanding of the effect of probiotics supplement on the immune system and inflammatory responses among UC patients and subsequent therapeutic benefits. Content A narrative review of all the relevant published papers known to the author was conducted. Summary UC is a chronic inflammatory bowel disease (IBD) that results in inflammation and ulceration of the colon and rectum. The primary symptoms of active disease are diarrhea, abdominal pain, and rectal bleeding. About 70% of the human immune system (mucosal-associated lymphoid tissue) originates in the intestine. Probiotics are live microorganisms that help in stabilizing the gut microbiota (nonimmunologic gut defense), restores normal flora, and enhance the humoral immune system. Probiotics especially Bifidobacterium, Saccharomyces boulardii, and lactic acid-producing bacteria have been used as an adjunct therapy for treating UC to ameliorate disease-related symptoms and reduce relapse rate. Probiotics, in general, modulate the immune system through their ability to enhance the mucosal barrier function, or through their interaction with the local immune system to enhance regulatory T cell responses, decrease the pro-inflammatory cytokines such as tumor necrosis factor alpha and interleukin 1 beta and increase anti-inflammatory factor interleukin 10. Outlook More studies are needed to explore the properties of the various probiotic bacterial strains, their different uses, as well as the dosage of probiotics and duration for treating different disorders. Further clinical investigations on mechanisms of action and how probiotics modulate the immune system may lead to further advances in managing IBD.
