Effectiveness of fecal microbiota transplantation for severe diarrhea after drug-induced hypersensitivity syndrome.

ABSTRACT: The aim of this study was to assess effectiveness of fecal microbiota transplantation (FMT) in treating intestinal failure associated with drug-induced hypersensitivity syndrome (DIHS).A 32-year-old Chinese woman, who developed DIHS-associated multiple organ dysfunction syndrome (MODS) manifesting as combined dysfunction of the intestine, liver, and kidney, was treated with 4 times of FMT at a frequency of once every 6 days. The structure and composition of the patient's fecal microbiota were analyzed by 16S rRNA-based molecular techniques. The clinical outcomes after FMT treatment were assessed by abdominal contrast-enhanced computed tomography (CT), characterization of fecal microbiota, measurement of serum inflammatory markers, and other clinical examinations.After 4 rounds of FMT were administered, the patient showed dramatic improvement in MODS and severe diarrhea with these clinical conditions under control. We consistently observed significant alteration in her gut microbiota, mainly involving considerable enrichment in Firmicutes members and depletion of Proteobacteria opportunistic organisms. Moreover, this reconstituted bacterial community composition correlated with fecal output, T helper cells, and inflammatory markers. Abdominal contrast-enhanced CT scans before and after FMT indicated significant improvement in inflammation and edema within the small intestine and colon of the patient. Notably, after completion of the fourth FMT, the level of inflammation in the intestine and colon had returned to normal. Over 6 months of follow-up, the intestinal mucous remained normal.Our results represent a breakthrough in the clinical management of MODS and suggest new therapeutic avenues to pursue for microbiota-related indications.

Project description:Altered gut microbiota are assumed to be involved in the pathogenesis of irritable bowel syndrome (IBS). However, gut microbiota alterations reported in different studies are divergent and sometimes even contradictory. To better elucidate the relationship between altered gut microbiota and IBS, we characterized fecal microbiota of diarrhea-predominant IBS (IBS-D) patients and further explored the effect of rifaximin on gut microbiota using bacterial 16S rRNA gene-targeted pyrosequencing. In our study, IBS-D patients defined by Rome III criteria and age-and-gender matched healthy controls (HC) were enrolled to investigate the fecal microbiota alterations. These IBS-D patients were then treated with rifaximin for 2 weeks and followed up for 10 weeks. Fecal microbiota alterations, small intestine bacterial overgrowth (SIBO) and gastrointestinal (GI) symptoms of IBS-D patients were analyzed before and after treatment. Our results showed fecal microbiota richness but not diversity was decreased in IBS-D patients as compared to HC and there were alterations of fecal microbiota at different taxonomy levels. The abundant phyla Firmicutes was significantly decreased and Bacteroidetes was increased in IBS-D patients. Moreover, the alterations of predominant fermenting bacteria such as Bacteroidales and Clostridiales might be involved in the pathophysiology of IBS-D. In addition, rifaximin was effective in terms of SIBO eradication and even GI symptoms of IBS-D patients achieved at least 10-week improvement after treatment. Furthermore, rifaximin induced alterations of some special bacteria rather than affected the overall composition of microbiota in IBS-D patients. Meanwhile, a potential decrease in propanoate and butanoate metabolism was found in these IBS-D patients after rifaximin treatment. Taken together, there were alterations of gut microbiota in IBS-D patients as compared to HC. Rifaximin could relieve GI symptoms, modify gut microbiota in IBS-D patients and eradicate SIBO in those patients with SIBO, suggesting an additional therapeutic mechanism of rifaximin in the treatment of IBS-D. Our findings of compositional gut microbiota alterations in IBS-D and the effect of rifaximin on the gut microbiota implied that altered gut microbiota were associated with the pathogenesis of IBS.

Project description:BACKGROUND:Antibiotic-associated diarrhea (AAD) is a risk factor for exacerbating the outcome of critically ill patients. Dysbiosis induced by the exposure to antibiotics reveals the potential therapeutic role of fecal microbiota transplantation (FMT) in these patients. Herein, we aimed to evaluate the safety and potential benefit of rescue FMT for AAD in critically ill patients. METHODS:A series of critically ill patients with AAD received rescue FMT from Chinese fmtBank, from September 2015 to February 2019. Adverse events (AEs) and rescue FMT success which focused on the improvement of abdominal symptoms and post-ICU survival rate during a minimum of 12 weeks follow-up were assessed. RESULTS:Twenty critically ill patients with AAD underwent rescue FMT, and 18 of them were included for analysis. The mean of Acute Physiology and Chronic Health Evaluation (APACHE) II scores at intensive care unit (ICU) admission was 21.7 ± 8.3 (range 11-37). Thirteen patients received FMT through nasojejunal tube, four through gastroscopy, and one through enema. Patients were treated with four (4.2 ± 2.1, range 2-9) types of antibiotics before and during the onset of AAD. 38.9% (7/18) of patients had FMT-related AEs during follow-up, including increased diarrhea frequency, abdominal pain, increased serum amylase, and fever. Eight deaths unrelated to FMT occurred during follow-up. One hundred percent (2/2) of abdominal pain, 86.7% (13/15) of diarrhea, 69.2% (9/13) of abdominal distention, and 50% (1/2) of hematochezia were improved after FMT. 44.4% (8/18) of patients recovered from abdominal symptoms without recurrence and survived for a minimum of 12 weeks after being discharged from ICU. CONCLUSION:In this case series studying the use of FMT in critically ill patients with AAD, good clinical outcomes without infectious complications were observed. These findings could potentially encourage researchers to set up new clinical trials that will provide more insight into the potential benefit and safety of the procedure in the ICU.
