Background: Irritable bowel syndrome (IBS) has been associated with microbial dysbiosis. Aim: To investigate the efficacy of faecal microbiota transplantation (FMT) in the treatment of IBS. Methods: Forty-nine IBS patients were randomised to receive autologous or allogenic FMT via colonoscopy. The primary endpoint was a sustained, minimum of 50point, reduction in the IBS Symptom Severity Score. The secondary outcomes were levels of anxiety and depression, changes in quality of life, gut microbiota and faecal water content as assessed with validated questionnaires, intestinal microbiota composition and stool dry weight.Results: The primary endpoint was not achieved in either group. However, there was a transient reduction in the mean IBS Symptom Severity Score in the FMT group at 12 weeks after treatment as compared to baseline (P = 0.01). The groups did not differ in the number of patients achieving clinical response at 12 weeks. In the FMTtreated patients, microbial composition had changed to resemble that of the donor and the stool water content decreased significantly compared to baseline. The depression score decreased in patients with a reduction in IBS symptoms after FMT, but not in those placebo-treated patients who experienced a reduction in IBS symptoms. Conclusions: FMT provided only a transient relief of symptoms, although it induced a sustained alteration in the microbiota of IBS patients. Therefore, FMT delivered by a single infusion via colonoscopy cannot be recommended as a treatment for IBS in clinical practice. ClinicalTrials.Org, Trial registration number: NCT03561519.

BackgroundIn a previous study we observed an increasing trend in candidemia in Finland in the 1990s. Our aim was now to investigate further population-based secular trends, as well as outcome, and evaluate the association of fluconazole consumption and prophylaxis policy with the observed findings.MethodsWe analyzed laboratory-based surveillance data on candidemia from the National Infectious Diseases Register during 2004-2007 in Finland. Data on fluconazole consumption, expressed as defined daily doses, DDDs, was obtained from the National Agency for Medicines, and regional prophylaxis policies were assessed by a telephone survey.ResultsA total of 603 candidemia cases were identified. The average annual incidence rate was 2.86 cases per 100,000 population (range by year, 2.59-3.09; range by region, 2.37-3.85). The highest incidence was detected in males aged >65 years (12.23 per 100,000 population). Candida albicans accounted for 67% of cases, and C. glabrata ranked the second (19%), both without any significant change in proportions. C. parapsilosis accounted for 5% of cases and C. krusei 3% of cases. The one-month case-fatality varied between 28-32% during the study period. Fluconazole consumption increased from 19.57 DDDs per 100,000 population in 2000 to 25.09 in 2007. Systematic fluconazole prophylaxis was implemented for premature neonates, patients with acute leukemias and liver transplant patients.ConclusionThe dominant proportion of C. albicans remained stable, but C. glabrata was the most frequent non-albicans species. The proportion of C. glabrata had increased from our previous study period in the presence of increasing use of fluconazole. The rate of candidemia in Finland is still low but mortality high like in other countries.

Extraintestinal CDIs occur mainly in hospitalized patients with significant comorbidities. Extraintestinal CDIs in the abdominal area may result from either intestinal perforation after infection or after intestinal surgery. Wound infections may result from colonization by feces. Clostridium difficile may reach distant sites via bacteremia. Mortality in extraintestinal CDIs is associated with the severity of underlying diseases.

A prospective, randomized, double-blind study was designed to compare Clostridium difficile immune whey (CDIW) with metronidazole for treatment of laboratory-confirmed, recurrent, mild to moderate episodes of Clostridium difficile-associated diarrhoea (CDAD). CDIW was manufactured by immunization of cows in their gestation period with inactivated C. difficile vaccine. The resulting colostrum was processed, immunoglubulins were concentrated and the end-product containing high titres of C. difficile immunoglobulin was used as CDIW. 20 patients received metronidazole at a dosage of 400 mg t.i.d. and 18 patients CDIW 200 ml t.i.d. The study was interrupted early because of the bankruptcy of the sponsor. After 14 d of treatment, all 20 (100%) of 20 patients had responded to metronidazole therapy, compared with 16 (89%) of 18 who had received CDIW. 70 d after the beginning of treatment, sustained responses were observed in 11 (55%) of 20 patients receiving metronidazole and 10 (56%) of 18 patients treated with CDIW. In this preliminary study CDIW was as effective as metronidazole in the prevention of CDAD recurrences and it was well tolerated.

We herein describe the establishment of the Helsinki Vascularized Composite Allotransplantation (VCA) program and its execution in the first two face transplant cases. Methods & patients: The Helsinki VCA program initially required the fulfillment of legal, hospital, financial, and ethical requirements. Thereafter, the assembling of a multidisciplinary team commenced. A team of Plastic, maxillofacial and ENT surgeons comprise the facial VCA team. The protocol involves collaboration with the Solid Organ Transplant (SOT) team, transplant immunology, immunosuppression, microbiology, psychiatric evaluation, well-defined VCA indi-1 AL and PL designed and performed the study, collected and analyzed data and wrote the paper. PL was the leader of the program. HM, HJ, JL, V-JA, SJ, A-JÄ, AE, SS, HI and AM all participated in the development of the face transplant program and collected and analyzed data and contributed to writing the paper.

Fecal microbiota transplantation (FMT) is an effective therapy for recurrent Clostridioides difficile infection (rCDI) and is also considered a potential treatment for a wide range of intestinal and systemic diseases. FMT corrects the microbial dysbiosis associated with rCDI, and the engraftment of donor microbiota is likely to play a key role in treatment efficacy. For disease indications other than rCDI, FMT treatment efficacy has been moderate. This may be partly due to stronger resilience of resident host microbiota in patients who do not suffer from rCDI. In rCDI, patients typically have undergone several antibiotic treatments prior to FMT, depleting the microbiota. In this study, we addressed the effect of broad-spectrum antibiotics (Ab) as a pre-treatment to FMT on the engraftment of donor microbiota in recipients. We conducted a pre-clinical study of FMT between two healthy mouse strains, Balb/c as donors and C57BL/6 as recipients, to perform FMT within the same species and to mimic interindividual FMT between human donors and patients. Microbiota composition was assessed with high-throughput 16S rDNA amplicon sequencing. The microbiota of Balb/c and C57BL/6 mice differed significantly, which allowed for the assessment of microbiota transplantation from the donor strain to the recipient. Our results showed that Ab-treatment depleted microbiota in C57BL/6 recipient mice prior to FMT. The diversity of microbiota did not recover spontaneously to baseline levels during 8 weeks after Ab-treatment, but was restored already at 2 weeks in mice receiving FMT. Interestingly, pre-treatment with antibiotics prior to FMT did not increase the overall similarity of the recipient’s microbiota to that of the donor’s, as compared with mice receiving FMT without Ab-treatment. Pre-treatment with Ab improved the establishment of only a few donor-derived taxa, such as Bifidobacterium, in the recipients, thus having a minor effect on the engraftment of donor microbiota in FMT. In conclusion, pre-treatment with broad-spectrum antibiotics did not improve the overall engraftment of donor microbiota, but did improve the engraftment of specific taxa. These results may inform future therapeutic studies of FMT.
