Gastroenteric tube feeding plays a major role in the management of patients with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, and patients who are critically ill. However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.
Most segments of the gastrointestinal tract secrete HCO3−, but the molecular nature of the secretory mechanisms has not been identified. We had previously speculated that the regulator for intestinal electrogenic HCO3− secretion is the cystic fibrosis transmembrane regulator (CFTR) channel. To prove this hypothesis, we have now measured HCO3− secretion by pH‐stat titration, and recorded the electrical parameters of in vitro duodenum, jejunum and ileum of mice deficient in the gene for the CFTR protein (‘CF‐mice’) and their normal littermates. Basal HCO3− secretory rates were reduced in all small intestinal segments of CF mice. Forskolin, PGE2, 8‐bromo‐cAMP and VIP (cAMP‐dependent agonists), heat‐stable enterotoxin of Escherichia coli (STa), guanylin and 8‐bromo‐cGMP (cGMP‐dependent agonists) and carbachol (Ca2+ dependent) stimulated both the short‐circuit current (ISC) and the HCO3− secretory rate (JHCO3‐) in all intestinal segments in normal mice, whereas none of these agonists had any effect on JHCO3‐ in the intestine of CF mice. To investigate whether Cl−–HCO3− exchangers, which have been implicated in mediating the response to some of these agonists in the intestine, were similarly active in the small intestine of normal and CF mice, we studied CF gradient‐driven 36Cl− uptake into brush‐border membrane (BBM) vesicles isolated from normal and CF mouse small intestine. Both the time course and the peak value for 4,4’‐diisothiocyanostilbene‐2’,2‐disulphonic acid (DIDS)‐inhibited 36Cl− uptake was similar in normal and CF mice BBM vesicles. In summary, the results demonstrate that the presence of the CFTR channel is necessary for agonist‐induced stimulation of electrogenic HCO3− secretion in all segments of the small intestine, and all three intracellular signal transduction pathways stimulate HCO3− secretion exclusively via activation of the CFTR channel.
BACKGROUND & AIMS: Swallowed topical-acting corticosteroids are recommended as first-line therapy for eosinophilic esophagitis (EoE). Asthma medications not optimized for esophageal delivery are sometimes effective, although given offlabel. We performed a randomized, placebo-controlled trial to assess the effectiveness and tolerability of a budesonide orodispersible tablet (BOT), which allows the drug to be delivered to the esophagus in adults with active EoE. METHODS: We performed a double-blind, parallel study of 88 adults with active EoE in Europe. Patients were randomly assigned to groups that received BOT (1 mg twice daily; n ¼ 59) or placebo (n ¼ 29) for 6 weeks. The primary end point was complete remission, based on clinical and histologic factors, including dysphagia and odynophagia severity 2 on a scale of 0-10 on each of the 7 days before the end of the double-blind phase and a peak eosinophil count <5 eosinophils/high power field. Patients who did not achieve complete remission at the end of the 6-week double-blind phase were offered 6 weeks of open-label Gastroenterology 2019;157:74-86 CLINICAL AT treatment with BOT (1 mg twice daily). RESULTS: At 6 weeks, 58% of patients given BOT were in complete remission compared with no patients given placebo (P < .0001). The secondary end point of histologic remission was achieved by 93% of patients given BOT vs no patients given placebo (P < .0001). After 12 weeks, 85% of patients had achieved remission. Six-week and 12-week BOT administration were safe and well tolerated; 5% of patients who received BOT developed symptomatic, mild candida, which was easily treated with an oral antifungal agent. CONCLUSIONS: In a randomized trial of adults with active EoE, we found that budesonide oral tablets were significantly more effective than placebo in inducing clinical and histologic remission.

The overall prevalence of anemia in patients with Crohn's disease was 27% (95% confidence interval, 19-35) and 21% (95% confidence interval, 15-27) in patients with ulcerative colitis. Thereby, 57% of the anemic patients were iron deficient.
Background and Aims: The IL-12/23 inhibitor ustekinumab (UST) opened up new treatment options for patients with Crohn’s disease (CD). Due to the recent approval, real-world German data on long-term efficacy and safety are lacking. This study aimed to assess the clinical course of CD patients under UST therapy and to identify potential predictive markers. Methods: Patients with CD receiving UST treatment in three hospitals and two outpatient centers were included and retrospectively analyzed. Rates for short- and long-term remission and response were analyzed with the help of clinical (Harvey–Bradshaw Index (HBI)) and biochemical (C-reactive protein (CRP), Fecal calprotectin (fCal)) parameters for disease activity. Results: Data from 180 patients were evaluated. One-hundred-and-six patients had a follow-up of at least eight weeks and were included. 96.2% of the patients were pre-exposed to anti- TNFα agents and 34.4% to both anti-TNFα and anti-integrin antibodies. The median follow-up was 49.1 weeks (95% CI 42.03-56.25). At week 8, 51 patients (54.8%) showed response to UST, and 24 (24.7%) were in remission. At week 48, 48 (51.6%) responded to UST, and 25 patients (26.9%) were in remission. Steroid-free response and remission at week eight was achieved by 30.1% and 19.3% of patients, respectively. At week 48, 37.6% showed steroid-free response to UST, and 20.4% of the initial patient population was in steroid-free remission. Conclusion: Our study confirms short- and long-term UST effectiveness and tolerability in a cohort of multi-treatment-exposed patients.
Summary Background : Crohn's disease is complicated by fistulas in 20–40% of patients at some time during the course of their illness. Azathioprine has been reported to heal fistulas in 30–40% of cases. Long‐lasting effects by the anti‐tumour necrosis factor‐α antibody infliximab most often require repeated infusions. Methotrexate has been shown to be an effective drug in maintaining remission in Crohn's disease. Aim : To evaluate the combination of infliximab and methotrexate as therapy for fistulas in patients with Crohn's disease. Methods : Twelve consecutive patients (mean age, 29.5 years) with fistulizing Crohn's disease resistant or intolerant to azathioprine were followed prospectively. Patients received three infusions of infliximab (5 mg/kg) and long‐term methotrexate (20 mg/week). Therapy success was defined as sustained closure of fistulas ≥ 6 months after fistula closure. Results : In four of the 12 patients, complete closure of fistulas that persisted for ≥ 6 months (median follow‐up, 13.25 months) was observed. In three further patients, a partial response was noted. In five patients, persistent therapy success could not be achieved or therapy had to be stopped due to side‐effects. Conclusions : A combination of infliximab with long‐term methotrexate may be a promising concept in fistulizing Crohn's disease. Our data indicate the need for larger controlled trials.
Our investigation demonstrates for the first time gender-specific differences in the therapeutic management in a large cohort of IBD patients.
Although intravenous iron supplementation is recommended in IBD patients, current German practice still relies on oral therapy, even in severe anaemia. The high incidence of severe anaemia in this cohort reflects inadequate iron replacement and status monitoring. While the proportion of IBD patients with inadequately treated anaemia/iron deficiency is unknown, greater awareness of existing guidelines for iron deficiency management in IBD patients appears necessary.
