简要总结
Colonization by Multiple Drug Resistant Organisms (MDROs) during patient hospitalization requires expensive isolation measures and renders the return or transfer to other departments or institutions often impossible. Currently there is no specific treatment available. Patients have to wait for spontaneous clearance which can take months or does not happen at all.
The study will test the effect of Fecal Microbiota Transfer (FMT) on gut MDRO colonization. The focus will be on patients with a long-term colonization by Gram-negative bacteria for which isolation is warranted. Participants will be randomized into two treatment groups; allogenic FMT versus autologous FMT. A third group of participants will be monitored but will not receive an FMT. Decolonization rate will be compared one month after treatment. Additionally gut microbial composition will be studied up to one year after FMT.
详细描述
This double-blind controlled randomized study will test the efficacy of Fecal Microbiota Transfer (FMT) on gut Multiple Drug Resistant Organism (MDRO) colonization.
Participants:
The study targets hospitalized patients (>18 years old) that need to stay in isolation because of colonization by Carbapenem-resistant Enterobacteriales (CRE), non-E. coli Enterobacteriales that produce extended spectrum beta-lactamase (ESBL) or Multi Drug Resistant (MDR) Pseudomonas and MDR Acinetobacter species. Participants will be randomized in two groups (allogenic and autologous FMT). Additionally a third group of participants will be monitored without intervention.
Treatment:
Participants in the allogenic FMT- group will receive treatment using healthy donor microbiota preferably through naso-duodenal/-jejunal administration (Cortrak). Donor material will be supplied by the Ghent Stool Bank. The colonization status will be monitored on a regular basis (at least once per week) by culturing fecal swabs. Additionally fecal samples will be taken on fixed time points for microbial composition analysis (16S ribosomal ribonucleic acid metagenomics).

入选标准
- •Participants must be at least 18 years of age, and must sign the 'informed consent' form and thus agree with the data collection, sampling and FMT.
- •At least 2 consecutive confirmations of MDRO colonization in faeces, which complicate the necessary follow-up and/or therapy for the patient.
- •Participants must be able to endure the treatment (evaluated by treating physician).
排除标准
- •Inflammatory bowel disease (Crohn's disease, ulcerative colitis ...)
- •Diagnosed hereditary blood disease (Haemophilia, Von Willebrand ...)
- •Chronic liver disease
- •Active drug use or alcohol abuse / dependence, which according to the researchers' opinion may interfere with the patient's participation in the study
- •Simultaneous use of probiotics (except yoghurt)
- •Existing immune deficiency (congenital or acquired), or concomitant immunomodulatory treatment (including systemic corticosteroids) in the 12 weeks prior to randomization, nasal or inhaled corticosteroid use is permitted
- •Positive pregnancy test (or potentially pregnant)
- •Breastfeeding
- •Severe food allergy (anaphylaxis, urticarial)
- •Antibiotic treatment up to 7 days before FMT, or planned to start within one month after FMT.
研究组 & 干预措施
Allogenic FMT
Participants in the allogenic FMT- group will receive FMT-treatment using healthy donor microbiota supplied by the Ghent Stool Bank. The donor stool (50g) is processed shortly after production and tested intensively. It's frozen at -80°C until administration via naso-duodenal/-jejunal tube (Cortrak).
干预措施: Allogenic FMT (Biological)
Autologous FMT
Participants in the autologous FMT- group will receive FMT-treatment using their own microbiota to account for effects due to the treatment itself. Their stool is processed as close to the treatment as feasible. It's processed and frozen at -80°C until administration via naso-duodenal/-jejunal tube (Cortrak).
干预措施: Autologous FMT (Biological)
结局指标
主要结局
Number of participants with decolonization success/failure
时间窗: 1 month after treatment
These participants were screened positive for MDRO's in stool cultures before treatment and monitored at least once per week up to 1 month after treatment. "Decolonization" = 3 consecutive negative cultures in minimal time span of 2 weeks.
次要结局
- Treatment effect on microbial community in participants(up to 1 year after treatment)
- Treatment tolerability(1 month after treatment)
- Side effects(up to 1 year after treatment)
