Background and Aims: Many studies have shown a high effectiveness of fecal microbiota transplantation (FMT) in treatment of recurrent or refractory Clostridioides difficile infection (CDI). Nevertheless, data on long term outcomes and complications after FMT are still lacking. We aimed to evaluate the efficacy, the peri- procedural safety profile and the long-term efficacy and safety of FMT for recurrent CDI during a median follow up period of 24 months. Methods: Our study included 60 consecutive patients that were treated from 2015 to 2019 for recurrent CDI. In all patients FMT was performed through the nasoenteric tube placed during gastroscopy. Fresh donor feces were used for FMT from unrelated donors. Pre-FMT preparation included CDI treatment with oral vancomycin 500 mg q.i.d. for at least five days and proton pump inhibitor (PPI) administration before FMT. Follow up data included information about recurrent CDI episodes, early and late complications, health status at 3, 12 and 24 months after FMT. Results: FMT was performed for 60 patients (median age 72.5 years) with recurrent CDI. Clinical improvement after the first FMT procedure was observed in 48 patients (80%). Ten of 12 initially non-responding patients had a clinical resolution after a second FMT leading to an increased overall cure rate of 96.7 %. The remaining two patients needed a third FMT with a final overall cure rate of 100%. Nine of 60 patients were under immunosuppressive therapy. Six immunosuppressed patients were in the group of initial responders and the remaining three in the initially non-responder group. We observed a very low rate of adverse events in the short and long-term after FMT. During the first eight weeks after the FMT procedure, the death of three patients occurred, but they were not related to the FMT procedure. Patients were followed up for a median of 20 months, with the range from 12 to 55 months. During the follow-up period no long-term serious adverse events (SAE) were documented. Conclusions: Our study confirms excellent efficacy rates of FMT in the treatment of recurrent CDI. In addition, this study shows that it is possible to avoid short term SAE when FMT is administered via a nasoenteric tube by following a very stringent peri-procedural patient follow-up protocol. Our study also demonstrates good safety with a low rate of long-term adverse events after FMT.

Background: Various noninvasive biomarkers have been used in the diagnosis, prognosis, and treatment of different gastrointestinal (GI) diseases for years. Novel technological developments and profound perception of molecular processes related to GI diseases over the last decade have allowed researchers to evaluate genetic, epigenetic, and many other potential molecular biomarkers in different diseases and clinical settings. Here, we present a review of recent and most relevant articles in order to summarize major findings on novel biomarkers in the diagnosis of benign and malignant GI diseases. Summary: Genetic variations, noncoding RNAs (ncRNAs), cell-free DNA (cfDNA), and microbiome-based biomarkers have been extensively analyzed as potential biomarkers in benign and malignant GI diseases. Multiple single-nucleotide polymorphisms have been linked with a number of GI diseases, and these observations are further being used to build up disease-specific genetic risk scores. Micro-RNAs and long ncRNAs have a large potential as noninvasive biomarkers in the management of inflammatory bowel diseases and GI tumors. Altered microbiome profiles were observed in multiple GI diseases, but most of the findings still lack translational clinical application. As of today, cfDNA appears to be the most potent biomarker for early detection and screening of GI cancers. Key Messages: Novel noninvasive molecular biomarkers show huge potential as useful tools in the diagnostics and management of different GI diseases. However, the use of these biomarkers in real-life clinical practice still remains limited, and further large studies are needed to elucidate the ultimate role of these potential noninvasive clinical tools.

The outbreak of coronavirus disease 2019 (COVID-19) has recently become a serious issue affecting thousands of people worldwide. It is known that a substantial proportion of patients infected with COVID-19 have abnormal liver function tests; however, the consequences of this information is still not clear. Here we present the first case report of a patient with liver cirrhosis and COVID-19 in our centre. Resolution of COVID-19 symptoms was observed after six days of fever onset. We observed only slight fluctuations of liver enzymes, bilirubin levels and INR without clinical consequences in our case. We suggest testing for severe acute respiratory syndrome coronavirus on any cirrhotic patient on initial presentation, even without symptoms of COVID-19 in areas where the epidemic was prevalent.
