Abstract
Ulcerative colitis, a chronic inflammatory condition affecting the rectum and colon to varying degrees, is linked to a dysregulated immune response and the microbiota. Sodium (aS,9R)-3-hydroxy-16,17-dimethoxy-15-oxidotricyclo[12.3.1.12,6]nonadeca-1(18),2,4,6(19),14,16-hexene-9-yl sulfate hydrate (SDH) emerges as a novel diarylheptane compound aimed at treating inflammatory bowel diseases. However, the mechanisms by which SDH modulates these conditions remain largely unknown. In this study, we assessed SDH's impact on the clinical progression of dextran sodium sulfate (DSS)-induced ulcerative colitis. Our results demonstrated that SDH significantly mitigated the symptoms of DSS-induced colitis, reflected in reduced disease activity index scores, alleviation of weight loss, shortening of the colorectum, and reduction in spleen swelling. Notably, SDH decreased the proportion of Th1/Th2/Th17 cells and normalized inflammatory cytokine levels in the colon. Furthermore, SDH treatment modified the gut microbial composition in mice with colitis, notably decreasing Bacteroidetes and Proteobacteria populations while substantially increasing Firmicutes, Actinobacteria, and Patescibacteria. In conclusion, our findings suggest that SDH may protect the colon from DSS-induced colitis through the regulation of Th1/Th2/Th17 cells and gut microbiota, offering novel insights into SDH's therapeutic potential.

Complementary Therapeutic Effect of Fecal Microbiota Transplantation in Ulcerative Colitis after the Response to Anti-Tumor Necrosis Factor Alpha Agent Was Lost: A Case Report. Biomedicines 2024; 12:800. [PMID: 38672155 PMCID: PMC11048579 DOI: 10.3390/biomedicines12040800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 03/22/2024] [Accepted: 03/28/2024] [Indexed: 04/28/2024] Open
Abstract
In patients with ulcerative colitis (UC), the development of an antidrug antibody (ADA) to anti-tumor necrosis factor (TNF)α agent is a crucial problem which aggravates the clinical course of the disease, being cited as one of the most common causes for discontinuing anti-TNFα treatment. This is due to ADA eventually causing secondary LOR, leading to discontinuation of anti-TNFα treatment. Recently, research on the microbiome and relationship between worsening UC and dysbiosis has been conducted. Further, investigations on the association between the microbiome and secondary LOR are increasing. Here, we present the therapeutic effect of fecal microbiota transplantation (FMT) on a 42-year-old man with secondary LOR and high ADA levels. FMT has recently been used for the treatment of, and for overcoming, drug resistance through microbiome modification. Stool samples were collected from the patient before and 4 weeks after FMT. Symptoms, including hematochezia and Mayo endoscopy sub-scores, improved after FMT, while ADA levels decreased by one-third to less than half the value (29 ng/mL) compared to before FMT (79 ng/mL). Additionally, the trough level of infliximab became measurable, which reflects the improvement in the area under the concentration (AUC). Butyricicoccus, Faecalibacterium, Bifidobacterium, Ligilactobacillus, Alistipes, and Odoribacter, which regulate immune responses and alleviate inflammation, also increased after FMT. We report a case in which microbiome modification by FMT increased the AUC of anti-TNFα in a patient who developed secondary LOR during anti-TNFα treatment, thereby improving symptoms and mucosal inflammation.

Abstract
Patients affected by inflammatory bowel diseases (IBD) can nowadays benefit from a growing number of pharmacological options. However, in moderate-to-severe cases, the therapeutic response is still far from optimal, and treatment changes and optimizations are often required. Thus, researchers in this field are strongly engaged in studies aiming to identify new potential therapeutic targets. Extracellular vesicles (EVs) are tiny subcellular bodies with a phospholipid bilayer envelope containing bioactive molecules, which are released from different cells and are involved in intercellular communication. Recent pre-clinical data show their emerging role in the pathogenesis and treatment of IBD. In our review, we summarize current evidence about the function of EVs as active therapeutic agents in ulcerative colitis and Crohn's disease, analyzing the properties of EVs derived from different cellular sources and the mechanisms through which they may improve intestinal inflammation.
