• Patients receiving any antibiotics for treatment of an infection
• A history of allergy to any of the investigational products/components
• Patients meeting the North American Consortia for Study of End Stage Liver Disease (NACSELD) criteria for acute-on-chronic liver failure (ACLF) with ≥ 2 organ failures by NACSELD-ACLF criteria at time of enrollment
• Profoundly immunocompromised patients, including patients with primary immunodeficiency, solid organ transplant recipients, any history of hematopoietic stem cell transplant (HSCT), ongoing cancer treatment, neutropenia < 500 cells/mm3, HIV untreated or with CD4 < 200 cells/mm3, immunosuppressive medications, including rituximab, anti-cytokine therapy, anti-rejection medications, chronic corticosteroids (a dose ≥ 20mg of prednisone daily for ≥ 1 month), biologic therapy for autoimmune condition
• Patients who are allergic to both ampicillin/sulbactam and meropenem; These are the two empiric antibiotic therapies that every strain is susceptible to; If a patient is allergic to only one of these medications, they may still be approached for enrollment
• Patients with liver disease from Hepatitis C
• History of total colectomy
• Patients with untreated psychiatric conditions, including illicit substance use disorders, that may interfere with reliable follow-up
• Chronic or prophylactic antibiotic administration other than rifaximin, ciprofloxacin, or trimethoprim-sulfamethoxazole; -Rifaximin will be either temporarily held or switched to another non-antibiotic therapy (e.g. lactulose or sodium benzoate) during the treatment phase of the trial. Potential subjects in whom the treating hepatologist deem it unsafe to pause or switch from Rifaximin therapy during the 7-10 day treatment phase will be excluded from the study
• Patients with known intestinal barrier dysfunction, including active GI bleeding, enteropathy (including celiac disease), clinically active inflammatory bowel disease (Crohn's or Ulcerative Colitis), ischemic colitis, microscopic colitis, graft versus host disease (GVHD), or gastrointestinal malignancy; o Active inflammatory bowel disease (IBD) will be defined based on a combination of:; Symptoms (diarrhea and/or abdominal pain without another explanation); Laboratory evidence of inflammation (e.g. elevated CRP or fecal calprotectin without another explanation); and; Either radiologic, endoscopic, and/or histologic evidence of active IBD; If IBD is suspected, this will be investigated with the general GI consult service prior to approaching for enrollment; If patients carry a diagnosis of IBD but do not meet the above criteria, they will be eligible for enrollment unless their IBD is managed with a systemic immunosuppression medication (e.g. anti-TNF-alpha therapy); If any form of the above intestinal disorders is suspected, they will be investigated with the general GI consult service prior to approaching for enrollment
• Special populations:; Women of childbearing age will have a:; Negative serum pregnancy test at screening; Use a medically acceptable and highly effective method of birth control for at least 6 weeks following completion of treatment; Another investigational drug or LBP:; Prior use will be permitted; Concurrent use will preclude enrollment; Use will be restricted for the duration of the study (12 months after commensal consortia completion); Patients who are prescribed ACE-inhibitors and receive a consortium containing C. comes will receive more frequent blood pressure monitoring; Patients who are prescribed metformin will require either:; Switch to another medication for diabetes control; or; More frequent Vitamin B12 monitoring at 1, 3, 6, and 12 months of enrollment
• MELD score >30 at time of enrollment
• Patients who are currently admitted to the intensive care unit for vasoactive support or mechanical ventilation
• Patients with delayed gastrointestinal motility as evidenced by ≤ 2 bowel movements per week at the time of enrollment
• Patients with existing inflammatory arthritis
• Patients who do not intend to continue their care on a routine basis at the University of Chicago beyond 6 months from the time of enrollment
• Unable to participate based on medical judgement of the care team
• If a Vitamin B12 deficiency is discovered, it will be repleted as clinically indicated
