Abstract
Current treatments for chronic diarrhea have limited efficacy and several side effects. Probiotics have the potential to alleviate symptoms of diarrhea. This randomized, double-blind, placebo-controlled trial evaluates the effects of administering the probiotic Lactiplantibacillus plantarum P9 (P9) strain in young adults with chronic diarrhea (Clinical Trial Registration Number: ChiCTR2000038410). The intervention period lasts for 28 days, followed by a 14-day post-intervention period. Participants are randomized into the P9 (n = 93) and placebo (n = 96) groups, with 170 individuals completing the double-blind intervention phase (n = 85 per group). The primary endpoint is the diarrhea symptom severity score. Both intention-to-treat (n = 189) and per-protocol (n = 170) analyses reveal a modest yet statistically significant reduction in diarrhea severity compared to the placebo group (20.0%, P = 0.050; 21.4%, P = 0.048, respectively). In conclusion, the results of this study support the use of probiotics in managing chronic diarrhea in young adults. However, the lack of blood parameter assessment and the short intervention period represent limitations of this study.

Yu W, Kang C, Zhang Y, Li Q, Zhang Z, Zheng Y, Liu X, Yan J. The San-Qi-Xue-Shang-Ning formula protects against ulcerative colitis by restoring the homeostasis of gut immunity and microbiota. JOURNAL OF ETHNOPHARMACOLOGY 2023; 305:116125. [PMID: 36603786 DOI: 10.1016/j.jep.2022.116125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 12/28/2022] [Accepted: 12/29/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulcerative colitis (UC) is a major cause of morbidity and mortality due to repetitive remissions and relapses, and many severe complications, including colitis-associated cancer (CAC). The San-Qi-Xue-Shang-Ning (SQ) formula has been utilized in clinical practice to treat gut diseases, but its pharmacological evidence is limited and awaits elucidation. AIM OF THE STUDY Here, we elucidated the molecular mechanisms of the SQ formula. MATERIALS AND METHODS Its therapeutic value in combating UC and CAC was predicted from network pharmacology and weighted gene co-expression network analysis (WGCNA). Experimental colitis models were established by feeding dextran sodium sulfate (DSS) to C57BL/6N mice for 7 days, and they were subjected to the SQ formula for 14 days. High-throughput technologies and biochemical investigations were executed to corroborate the anti-colitis effect. RESULTS Network pharmacology and WGCNA demonstrated that the targets of the SQ formula were associated with interleukin-17 (IL-17), tumor necrosis factor (TNF), IL-1b and peroxisome proliferators-activated receptor (PPAR) signaling pathways, and correlated with the survival in patients with colorectal cancer. In mice with colitis, the SQ treatment hindered colitis progression in a dose-dependent manner, as evidenced by the rescued colon length and weight loss, improved colonic epithelial integrity, and abolished crypt loss. In addition to the suppressed serum IL-17, TNFα, and IL-1b levels, the SQ-treated colitis mice exhibited decreased colonic protein abundance of hypoxia-inducible factor-1α (HIF-1 α), PPARα, and Caspase3 (Casp3) with an increased PPARγ expression. Concurrently, the high dose of SQ promoted the alternative activation of peritoneal macrophages by increasing Arg1 and inhibiting iNOS2, thereby facilitating the migration of NCM460 cells and controlling TNF-induced reactive oxygen species production and apoptosis in intestinal organoids. In colitis-accompanied dysbiosis, the SQ formula reversed the decreased microbiota diversity indexes and restored the microbiome profile in the murine colitis models. CONCLUSION The SQ formula is a potent anti-colitis drug that facilitates inflammation resolution and restores gut microbiota homeostasis.

Protective Effect of Dietary Polysaccharides from Yellow Passion Fruit Peel on DSS-Induced Colitis in Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:6298662. [PMID: 36285298 PMCID: PMC9588357 DOI: 10.1155/2022/6298662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 08/17/2022] [Accepted: 09/27/2022] [Indexed: 11/17/2022]
Abstract
Inflammatory bowel disease (IBD) is a complex inflammatory disorder characterized by chronic and spontaneously relapsing inflammation of the gastrointestinal tract. IBD includes two idiopathic disorders: Crohn’s disease (CD) and ulcerative colitis (UC). In particular, UC causes inflammation and ulceration of the colon and rectum. There is no cure for UC. The pharmacological treatment is aimed at controlling and/or reducing the inflammatory process and promoting disease remission. The present study investigated the possible protective effects of soluble dietary fiber (SDF) isolated from yellow passion fruit peel in the dextran sulfate sodium- (DSS-) induced colitis model in mice, induced by 5% of DSS. The animals were treated with SDF (10, 30, or 100 mg/kg (po)), and the disease activity index was monitored. Colon tissues were collected, measured, and prepared for oxidative stress, inflammation, and histology analysis. SDF improved body weight loss, colon length, and disease activity index and prevented colonic oxidative stress by regulating GSH levels and SOD activity. Furthermore, SDF reduced colonic MPO activity, TNF-α, and IL-1β levels and increased IL-10 and IL-6 levels. As observed by histological analysis, SDF treatment preserved the colonic tissue, the mucus barrier, and reduced inflammatory cell infiltration. Although this is a preliminary study, taken together, our data indicate that SDF may improve the course of DSS-UC. More studies are needed to explore and understand how SDF promotes this protection.

Front Nutr 2022; 9:921875. [PMID: 35757257 PMCID: PMC9218693 DOI: 10.3389/fnut.2022.921875] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Accepted: 05/13/2022] [Indexed: 12/20/2022] Open
Abstract
Diarrhea is one of the common adverse reactions in antibiotic treatment, which is usually caused by the imbalance of intestinal flora, and probiotics play an important role in the structure of intestinal flora. Therefore, this experiment studied the regulatory effect of Lactiplantibacillus plantarum 2-33 on antibiotic-associated diarrhea (AAD) mice. First, the AAD mice model was established by the mixed antibiotic solution of gentamicin sulfate and cefradine. Then, the physiological indexes and diarrhea of mice were observed and recorded by gastric perfusion of low dose (1.0 × 107 CFU/ml), medium dose (1.0 × 108CFU/ml), and high dose (1.0 × 109 CFU/ml) strain 2-33. 16S rRNA gene V3-V4 regions were sequenced in colon contents of mice in control group, model group, self-healing group, and experimental group, respectively, and the diversity of intestinal flora and gene function prediction were analyzed. The results showed that the intestinal flora of AAD mice was not significantly regulated by gastric perfusion of strain 2-33 to 7 days, but the relative abundance and diversity of intestinal flora of AAD mice were significantly improved by gastric perfusion to 14 days (p < 0.05). In addition, at the genus level, the relative abundance of Lactobacillus increased significantly, and the relative abundance of Enterococcus and Bacillus decreased significantly (p < 0.05). In addition, the regulation of strain 2-33 on intestinal flora of AAD mice was time- and dose-dependent, short-term gastric perfusion, and low dose had no significant effect (p > 0.05). Strain 2-33 can significantly increase the levels of anti-inflammatory cytokines IL-4 and IL-10, significantly decrease the levels of proinflammatory cytokines TNF-α and IFN-γ (p < 0.05), and can also adjust carbohydrate metabolism, amino acid metabolism, and energy metabolism to normal levels, thus accelerating the recovery of intestinal flora structure of AAD mice. In summary, strain 2-33 can improve the structure and diversity of intestinal flora of AAD mice, balance the level of substance and energy metabolism, and play a positive role in relieving diarrhea, maintaining and improving the intestinal microecological balance.
