RESUMEN
BACKGROUND: Intestinal failure (IF) is defined by a need for intravenous (IV) supplementation. Patients may present with multiple morbidities, and IV treatments carry a risk for catheter-related complications. Few studies described patient characteristics and clinical outcomes according to type of IF. METHODS: We consecutively included patients who were admitted to a newly established inpatient IF unit (IFU) from 2013 through 2017. We evaluated patient characteristics and clinical outcomes of all patients' first admission. Outcomes included IF classification, length of stay, central line-associated blood stream infection (CLABSI), and discharge on home parenteral support (HPS). Follow-up was conducted six months after discharge for mortality and the continued need for HPS. RESULTS: A total of 236 patients were evaluated, including 39 (17%) with type 1 IF, 123 (52%) with type 2 IF, and 74 (31%) with type 3 IF. Of 91 who had a central venous catheter (CVC) on admission, CLABSI was present in 11 (12%). The CLABSI occurrence during admission was 2 (1%) of 173 patients with a CVC. Mean length of stay declined from mean 33 days (95% confidence interval (CI): 26.2-42.5) in 2013 to 15 days (95% CI: 12.2-17.7) in 2017 (p < 0.0001). Undiagnosed comorbidity was revealed in 165 patients (70%) with unchanged frequency during the study period (p = 0.8). Sixty-seven (28%) patients were discharged with HPS. CONCLUSIONS: Inpatients with IF present with multiple morbidities. CLABSI should be investigated on admission. A low inpatient CLABSI rate may be achieved through the implementation of a specialised IFU.

BACKGROUND: Clostridioides (Clostridium) difficile infection (CDI) is a leading cause of antibiotics-associated diarrhoea. Faecal microbiota transplantation (FMT) is effective for recurrent CDI and may be provided as a home treatment to frail, older people. METHODS: We present four consecutive patients with recurrent CDI, treated at home using nasojejunal tube-delivered or encapsulated donor faeces. The primary outcome was combined clinical resolution and a negative CD toxin test 8 weeks post-treatment. RESULTS: All four patients had severe CDI and all improved clinically following one FMT. Sustained resolution following one FMT was observed in one patient. Two patients had recurrence and received a second FMT using capsules; both achieved resolution. One patient who had recurrence declined from further FMT due to fear of relapse and was established on long-term vancomycin. No adverse events related to FMT were observed. CONCLUSION: Frail older people may benefit from FMT. Home treatment is a viable option and may be considered both for clinical cure and for palliation.

Clostridioides difficile infection may be complicated by co-infection with other pathogens. We here describe the successful use of faecal microbiota transplantation to eradicate concomitant C. difficile and extensively drug-resistant (XDR) KPC-producing Klebsiella pneumoniae. Donor microbiota efficiently engrafted in the patient, and a donor-like microbial assemblage persisted in the patient during six months follow-up. The report explores the potential for the donor microbiota to eradicate and replace multi-resistant microorganisms.

Renal transplant recipients (RTRs) are highly susceptible to infections, and antimicrobial resistance is an increasing problem with limited treatment options. Faecal microbiota transplantation (FMT) is effective for recurrent Clostridium difficile infection and may be used for patients with intestinal carriage of multidrug-resistant (MDR) microorganisms. We present a RTR who suffered from recurrent urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase-producing (ESBL+) Klebsiella pneumoniae. Blood and urinary isolates revealed the same antibiotic susceptibility pattern, and whole-genome sequencing confirmed identical isolates in blood and urine. Despite several treatments with meropenem, the patient experienced recurrent infections that caused hospitalisation. ESBL+ K. pneumoniae was isolated in faeces. In an attempt to decolonise the gut, FMT was performed. A few days after nasojejunal infusion of donor faeces, the patient experienced a single relapse of UTI. During the subsequent 12 months, no further episodes of UTI occurred. Absence of ESBL+ K. pneumoniae in urine and faeces was demonstrated during follow-up. We conclude that FMT may be an effective treatment in RTRs with recurrent UTIs caused by intestinal colonisation with MDR organisms.
RESUMEN
Fecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridioides difficile infection and is potentially beneficial in other microbiota-related disorders. The provision of FMT in routine clinical practice requires an extensive infrastructure that is reliant on voluntary donors. Alongside an increasing demand for FMT, the logistic barriers of a large-scale donor-dependent operation and the difficulties among health authorities to regulate FMT limit the dissemination of sustainable FMT services. Blood centers are large organizations that handle a multitude of donor-dependent operations on a daily basis. Blood and feces share many of the same dependencies, and feces may present a new opportunity for the blood services to handle. In this paper, we describe how an FMT service may be established and embedded within the blood service infrastructure, and we explain the benefits of using blood donors as feces donors. We further explore the current indications of FMT, the challenges related to the lack of legislation, and the future perspectives for blood banks to meet a new and increasing demand.

Nonalcoholic fatty liver disease (NAFLD) and its inflammatory and often progressive subtype nonalcoholic steatohepatitis (NASH) are becoming the leading cause of liver-related morbidity and mortality worldwide, and a primary indication for liver transplantation. The pathophysiology of NASH is multifactorial and not yet completely understood; however, innate immunity is a major contributing factor in which liver-resident macrophages (Kupffer cells) and recruited macrophages play a central part in disease progression. In this Review, we assess the evidence for macrophage involvement in the development of steatosis, inflammation and fibrosis in NASH. In this process, not only the polarization of liver macrophages towards a pro-inflammatory phenotype is important, but adipose tissue macrophages, especially in the visceral compartment, also contribute to disease severity and insulin resistance. Macrophage activation is mediated by factors such as endotoxins and translocated bacteria owing to increased intestinal permeability, factors released from damaged or lipoapoptotic hepatocytes, as well as alterations in gut microbiota and defined nutritional components, including certain free fatty acids, cholesterol and their metabolites. Reflecting the important role of macrophages in NASH, we also review studies investigating drugs that target macrophage recruitment to the liver, macrophage polarization and their inflammatory effects as potential treatment options for patients with NASH.

As the use of fecal microbiota transplantation (FMT) has gained momentum, an increasing need for continuous access to healthy feces donors has developed. Blood donors constitute a healthy subset of the general population and may serve as an appropriate group for recruitment. In this study, we investigated the suitability of blood donors as feces donors. In a prospective cohort study, we recruited blood donors onsite at a public Danish blood bank. Following their consent, the blood donors underwent a stepwise screening process: First, blood donors completed an electronic pre-screening questionnaire to rule out predisposing risk factors. Second, eligible blood donors had blood and fecal samples examined. Of 155 blood donors asked to participate, 137 (88%) completed the electronic pre-screening questionnaire, 16 declined, and 2 were excluded. Of the 137 donors who completed the questionnaire, 79 (58%) were excluded mainly due to having an allergy, being overweight, or presenting gastrointestinal complaints. Among the remaining 58 (37%) donors, complete blood and feces screenings were obtained from 46 (79%). Of these 46 donors, 15 (33%) were excluded primarily due to abnormal blood results or the presence of apathogenic intestinal parasites. Overall, 31 (20%; 95% confidence interval 14-27%) of the 155 blood donors qualified as feces donors. In conclusion, blood donors constitute a suitable and motivated population for a continuous recruitment of voluntary feces donors. We found that a stepwise recruitment procedure was feasible and that 20% of the blood donors were eligible for feces donation.
