[Treatment of severe flares in Crohn's disease and ulcerative colitis].

Background: In chronic inflammatory bowel diseases (IBD), severe flares are characterized by intense inflammatory activity and a high disease burden for patients. Treatment addresses both short-term goals (e.g.

Induction and maintenance of mucosal healing in Crohn's disease with ustekinumab in clinical practice across all care levels in Germany (MUCUS).

The impact of ustekinumab (UST) on mucosal- and fistula healing and extraintestinal manifestations (EIM) in Crohn's disease (CD) were not fully elucidated in the registration trials. In this prospective, multicenter study (EudraCT number: 2017-005151-83) we evaluated the German label real-world-effectiveness of UST to achieve the primary endpoint of combined clinical and endoscopic response at week 52 and several secondary endpoints. Of 79 screened we enrolled 52 patients (female n = 28, bionaïve n = 13, biologic n = 39).

Selective Uptake Into Inflamed Human Intestinal Tissue and Immune Cell Targeting by Wormlike Polymer Micelles.

Inflammatory bowel disease (IBD) has become a globally prevalent chronic disease with no causal therapeutic options. Targeted drug delivery systems with selectivity for inflamed areas in the gastrointestinal tract promise to reduce severe drug-related side effects. By creating three distinct nanostructures (vesicles, spherical, and wormlike micelles) from the same amphiphilic block copolymer poly(butyl acrylate)-block-poly(ethylene oxide) (PBA-b-PEO), the effect of nanoparticle shape on human mucosal penetration is systematically identified.

Fatigue in patients with inflammatory bowel disease-strongly influenced by depression and not identifiable through laboratory testing: a cross-sectional survey study.

Background: Fatigue is a debilitating and highly relevant symptom in patients with inflammatory bowel disease (IBD). However, awareness of fatigue and treatment options remains limited. This study was aimed at elucidating the influence of disease activity and common complications (pain, anemia, depression, anxiety and quality of life) on fatigue in patients with IBD to identify potential interventional targets for treating physicians.

Glucocorticoids regulate lipid mediator networks by reciprocal modulation of 15-lipoxygenase isoforms affecting inflammation resolution.

Glucocorticoids (GC) are potent anti-inflammatory agents, broadly used to treat acute and chronic inflammatory diseases, e.g., critically ill COVID-19 patients or patients with chronic inflammatory bowel diseases.

Treatment Strategies in Inflammatory Bowel Diseases.

Background: The prevalence of inflammatory bowel disease (IBD) is rising globally. In Germany, these conditions affect 0.7% of the population, or approximately 600 000 patients.

[Fecal microbiota transplantation: indications, risks and opportunities].

Fecal microbiome transfer (FMT) involving the transfer of the microbiome of healthy stool donors to patients with various diseases has been performed in Germany in clinical studies and individual treatment attempts. There is no doubt that FMT is an effective therapeutic principle for recurrent Clostridium difficile infection and ulcerative colitis. From a medico-legal point of view, it should be stressed that, in Germany, the microbiome to be transferred is regarded as a drug, the manufacture of which is subject to the Medicines Act and the risk information from the Federal Institute for Drugs and Medical Devices.

Transfer of FRozen Encapsulated multi-donor Stool filtrate for active ulcerative Colitis (FRESCO): study protocol for a prospective, multicenter, double-blind, randomized, controlled trial.

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease with significant morbidity and mortality. Although the precise cause remains unknown, disturbances in the intestinal microbial community have been linked to its pathogenesis. Randomized controlled trials in UC and relapsing Clostridioides difficile infection (CDI) have established fecal microbiota (FM) transfer (FMT) as an effective therapy.

[Inflammatory bowel disease during the COVID-19 pandemic: manifestations and management].

The COVID-19 pandemic is significantly affecting the lives of patients with inflammatory bowel disease (IBD). Those affected and their relatives have numerous questions about the risk of the disease, the course of a possible SARS-CoV-2 infection or the influence of CED-specific therapy on these. Many IBD patients also have additional questions about the safety and effectiveness of a vaccination against SARS-CoV-2.

[Effects of SARS-CoV-2 Infection on Symptoms and Therapy of Inflammatory Bowel Disease].

Introduction: The influence of a SARS-CoV-2 infection on inflammatory bowel disease (IBD) has not yet been well characterized and it is unclear whether this requires an adaptation of the immunosuppressive therapy.

Methods: A national register was established for the retrospective documentation of clinical parameters and changes in immunosuppressive therapy in SARS-CoV-2 infected IBD patients.

Results: In total, only 3 of 185 IBD patients (1.

Results from the German registry for refractory celiac disease.

Refractory celiac disease (RCD) refers to a rare subgroup of patients with celiac disease who show clinical signs of malabsorption despite a gluten-free diet. RCD is divided into an autoimmune phenotype (RCD type I) and pre-lymphoma (RCD type II). To reflect the clinical reality in managing this disease in Germany, a national register was established based on a questionnaire developed specifically for this purpose.

T Cell Response After SARS-CoV-2 Vaccination in Immunocompromised Patients with Inflammatory Bowel Disease.

Background: Vaccination is a promising strategy to protect vulnerable groups like immunocompromised inflammatory bowel disease [IBD] patients from an infection with SARS-CoV-2. These patients may have lower immune responses. Little is known about the cellular and humoral immune response after a SARS-CoV-2 vaccination in IBD patients.

An Update for Pharmacologists on New Treatment Options for Inflammatory Bowel Disease: The Clinicians' Perspective.

The introduction of anti-tumor necrosis factor antibodies resulted in a considerable expansion of the options available for the treatment of inflammatory bowel disease. Unfortunately, approximately one third of treated patients do not respond to these modalities, and drug efficacy may be lost over time. These drugs are also associated with contraindications, adverse events, and intolerance.

The COVID-19 Pandemic: Fears and Overprotection in Pediatric Patients with Inflammatory Bowel Disease and Their Families.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has influenced the lives of people worldwide. Little is known about the effects of the COVID-19 pandemic on the behavior and fears of pediatric patients with inflammatory bowel disease (IBD) and their families. We conducted a survey to determine the COVID-19 exposure, related perceptions, and information sources; medication compliance; and patients' and parents' behaviors, fears, and physician contact.

[A surgically relevant summary of the addendum to the S3 guidelines of the DGVS on Crohn's disease and ulcerative colitis : Treatment of chronic inflammatory bowel diseases in the COVID-19 pandemic].

In order to improve the care of patients with chronic inflammatory bowel diseases during the coronavirus disease 2019 (COVID-19) pandemic, the currently valid guidelines of the German Society for Gastroenterology, Digestive and Metabolic Diseases (DGVS) on Crohn's disease and ulcerative colitis were extended within a virtual conference to include current and practically relevant recommendations. The addendum addresses in particular the risk of COVID-19 infections in patients with chronic inflammatory bowel diseases, the diagnostics under the conditions of the pandemic, the consequences for the pharmacotherapy and operative treatment of the underlying disease. It also addresses general measures for protection against infections and for adjunctive treatment of patients with chronic inflammatory bowel diseases.

Self-assessment of treatment targets in patients with inflammatory bowel disease using a survey.

Background: Physicians can improve their relationships with patients by understanding and meeting patients' treatment targets, leading to higher adherence to therapy and improved disease prognosis. In the current study, we performed a questionnaire-based survey to further understand treatment targets in patients with inflammatory bowel disease (IBD).

Methods: We created a questionnaire based on a point-allocation scale with 10 treatment target items.

Towards an Interpretable Classifier for Characterization of Endoscopic Mayo Scores in Ulcerative Colitis Using Raman Spectroscopy.

Ulcerative colitis (UC) is one of the main types of chronic inflammatory diseases that affect the bowel, but its pathogenesis is yet to be completely defined. Assessing the disease activity of UC is vital for developing a personalized treatment. Conventionally, the assessment of UC is performed by colonoscopy and histopathology.

Inflammatory Bowel Disease in the COVID-19 Pandemic: the Patients' Perspective.

Background: The coronavirus disease 2019 [COVID-19] pandemic is affecting lives worldwide. The influence of inflammatory bowel disease [IBD] medication and IBD itself on COVID-19 is controversial. Additionally, IBD-focused guidance is scarce.

Fecal Microbiota Transfer.

Background: Fecal microbiota transfer (FMT) is increasingly being used in Ger- many, as in other countries, for the treatment of recurrent Clostridioides difficile infection (rCDI). FMT is now being performed both for research and in individual patients outside of clinical trials. No compulsory standards have been established to date for donor screening or for the method of fecal transfer.
