Oropharyngeal and nasopharyngeal specimens collected by swabbing are the pillars of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostics. Commercially available rapid antigen tests and self-sampling polymerase chain reaction services have made specimen collection available anytime and anywhere in nonmedical settings. In this study, we report the case of a 45-year-old man who accidentally ingested a swab during self-performed SARS-CoV-2 rapid antigen testing. Imaging studies revealed an elongated foreign body in the stomach. Urgent gastroscopy confirmed the presence of the swabbing applicator in the gastric lumen, which was retrieved using a loop without any complications. Millions of SARS-CoV-2 tests are performed daily, of which an increasing proportion are performed by laypeople. Foreign bodies account for a particular set of complications, which can be avoided by cautious sampling and using the correct technique. Radiopaque labeling of instruments would be useful. Otherwise, rare serious events can occur that may require immediate medical interventions., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2021, Molnár et al.)

Background : GEMINI trials demonstrated the therapeutic efficacy of vedolizumab (VDZ) in Crohn's disease (CD) and ulcerative colitis (UC). Research design and methods : Aim of this study was to determine the real-life effectiveness of VDZ on endoscopic healing in the Hungarian nationwide cohort of inflammatory bowel disease (IBD) patients based on the changes on clinical and endoscopic scores. Every adult IBD patient in the country (121 UC and 83 CD) who completed the short-term VDZ therapy was enrolled, of which 72 UC and 52 CD patients could complete the long-term therapy. Results : The rates of endoscopic healing were substantially higher in UC compared with CD patients during the short- and long-term therapy (52.9% vs. 21.7%, p < 0.0001, and 51.4% vs. 21.2%, p = 0.015, respectively). In CD, the rate of endoscopic healing was lower at week 14 compared with week 22 (14.5% vs. 37.0%, p = 0.026). Prior anti-TNF-α therapy (88.73%) was not associated with a significant decrease in therapeutic response. The average disease duration was significantly lower in CD patients achieving endoscopic healing at week 52 (11.75 vs. 5.27 years, p = 0.007). Conclusions : VDZ therapy is an effective therapeutic option in anti-TNF-α refractory IBD. However, the endoscopic healing rate was substantially lower and showed a significant delay in CD compared with UC.

Introduction: Adalimumab was approved for the treatment of ulcerative colitis refractory to conventional therapy several years later than infliximab in Europe. Due to the relatively low remission rate observed in Ultra trials, data on the efficacy of adalimumab in ulcerative colitis are really helpful in the daily practice., Aim: The aim of this study was to prospectively collect data on induction and maintenance adalimumab therapy in patients with ulcerative colitis treated in Hungarian centres., Method: This prospective study collected data of all patients with ulcerative colitis treated with adalimumab in 10 Hungarian centres. The primary endpoints of the study were rates of remission, response and primary failure at week 12, and the rate of continuous clinical response, remission and loss of response at weeks 30, and 52. Secondary endpoints were endoscopic outcome at week 52 and comparison of the efficacy of adalimumab between treatment naive and infliximab-experienced patients., Results: 73 patients with active ulcerative colitis were enrolled in the study. 75.3% of the patients exhibited clinical response after the induction at week 12. The probability of maintaining adalimumab treatment was 48.6% at week 52 with a continuous clinical response in 92% of these patients. Mucosal healing was achieved in 48.1% of the patients at week 52. Dose intensification was performed in 17.6% of the patients. Minor side effects developed in 4% of the patients and 5.4% of the patients underwent colectomy during the 1-year treatment period., Conclusions: These results coming from the real clinical setting demonstrate a favourable efficacy of adalimumab induction and maintenance therapy in patients with ulcerative colitis.

Background and Aim: Adalimumab [ADA] was approved for the treatment of ulcerative colitis [UC] refractory to conventional therapy in 2012 in Europe. Due to the observed discrepancies between clinical trials and practice, data on the outcome of ADA therapy are really needed from the real life. The aim of this study was to estimate the short- and long-term efficacy and safety of ADA in UC patients from each Hungarian biological centre., Patients and Methods: This prospective study consisted of UC patients treated with ADA in 10 Hungarian inflammatory bowel disease centres. The primary endpoints of the study were rates of continuous clinical response, remission, non-response and loss of response at Weeks 12, 30, and 52.The secondary endpoints included mucosal healing at Week 52 and the comparison of the efficacy of ADA between biological naive and infliximab [IFX]-treated groups. Colonoscopy was performed before starting the therapy and at Week 52., Results: In all, 73 active UC patients were enrolled in the study: 67.1% of the patients received previous IFX therapy; 75.3% of the patients showed short-term clinical response at Week 12. The probability of maintaining ADA was 48.6% at Week 52 with a continuous clinical response in 92% of these remaining patients. Mucosal healing was achieved in 48.1% of the patients at Week 52. Escalation of ADA was performed in 17.6%, and minor side effects developed in 4% of the patients; 5.4% of the patients underwent colectomy during the 1-year treatment period., Conclusion: UC is a progressive disease that may need early aggressive therapy to prevent structural and functional complications. The results of our study demonstrated the favourable efficacy of short- and long-term ADA treatment for patients with UC., (Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO).

Objective: Iron isomaltoside 1000 (Monofer®) is a high-dose intravenous (IV) iron, which in a recent 8 weeks trial in inflammatory bowel disease (IBD) subjects with iron deficiency anemia (IDA) demonstrated good tolerability and efficacy. The present trial is an extension to this trial, which evaluates the need for additional high IV iron doses to maintain a stable hemoglobin (Hb) ≥12.0 g/dl., Material and Methods: This was a prospective, open-label, 12 months trial of European IBD subjects willing to participate after completing the lead-in trial. Subjects were allowed re-dosing with 500-2000 mg single doses of iron isomaltoside 1000 infused over ∼15 min at 3 months intervals depending on a predefined algorithm. Outcome measures included Hb, safety parameters and need for additional iron dosing., Results: A total of 39 subjects were enrolled of which 34 subjects required re-dosing with a median cumulative 1-year dose of 1.8 g (mean cumulative dose 2.2 g). The mean (SD) Hb was 12.3 (1.5) g/dl at baseline, 12.8 (1.6) g/dl at 3 months, 12.8 (1.6) g/dl at 6 months, 12.9 (1.4) g/dl at 9 months and 12.9 (1.6) g/dl at 12 months. Seventy-four percent of subjects who had an Hb ≥12.0 g/dl at baseline were able to maintain Hb ≥12.0 g/dl till the end of the trial at 12 months. Nonserious probably related hypersensitivity reactions without significant hypotension were reported at the beginning of the infusion in two subjects, who recovered without sequelae., Conclusion: Repeated treatment of iron deficiency with iron isomaltoside 1000 could avoid episodes of IDA without major safety issues.

Background/aims: Smoking may alter the natural course of Crohn's disease (CD). Smokers are more likely to develop complications, relapses and have a greater risk for surgery. In contrast, in ulcerative colitis (UC), smoking might improve the disease course. Our aim was to assess the combined effect of disease phenotype, smoking, and immunomodulator [azathioprine (AZA), AZA/biological] treatment on the risk of intestinal resection/reoperation in CD and colectomy in UC., Patients/methods: Six hundred and eighty-one inflammatory bowel disease patients were analyzed (CD: 340, male/female: 155/185, duration: 9.4+/-7.5 years; UC: 341, male/female: 174/164, duration: 11.5+/-9.7 years). Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits. Medical records were retrospectively analyzed., Results: Smoking was present in 45.5% in CD and 15.8% in UC. CD patients who underwent at least one bowel resection comprised 46.5%. In an univariate analysis, disease location, behavior, AZA, or AZA/biological use before surgery [odds ratio (OR): 0.26 and 0.22, P<0.001] and smoking (OR: 1.61, P = 0.03) were associated with risk for first surgery. Smoking, AZA, or AZA/biological (P<0.001) use before first surgery and disease behavior were independently associated with risk for surgery in a proportional Cox-regression analysis. Perianal disease (OR: 3.2, P = 0.001) and frequent relapses (OR: 4.8, P<0.001) but not smoking, AZA, or AZA/biological use after first surgery were predictive for reoperation. In UC, the rate of colectomy was 5.6%. Disease location (P = 0.001) and smoking status (P = 0.02) were independently associated with risk for colectomy in a proportional Cox-regression analysis., Conclusion: Our data suggest that early AZA/biological therapy reduces the risk for first operation but not reoperation in CD, in both smokers and nonsmokers. In contrast, smoking was associated with a decreased need for colectomy in UC.

Aim: To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine (AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn's disease (CD)., Methods: Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed (M/F: 155/185, duration: 9.4 +/- 7.5 years) with a complete clinical follow-up. Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively. Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits., Results: A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean disease duration of 9.0 +/- 7.2 years. In a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/biological therapy use were independent predictors of disease behavior change. In a subsequent Kaplan-Meier survival analysis and a proportional Cox regression analysis, disease location (P = 0.001), presence of perianal disease (P < 0.001), prior steroid use (P = 0.006), early AZA (P = 0.005) or AZA/biological therapy (P = 0.002), or smoking (P = 0.032) were independent predictors of disease behavior change., Conclusion: Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients.

Background: Malignant oesophageal stenosis can be caused by cancer of the oesophagus, gastric cardia, lungs, mediastinum or, rarely, breast. Most of these cases are inoperable due to advanced stage of the disease, comorbidities or age of the patients; and palliative treatment can be applied only. The quality of life is mostly determined by the extent of dysphagia. Several methods are available to palliate dysphagia. Hereby, the authors review their results with palliation of malignant oesophageal obstruction applying self-expanding metal stents., Patients and Methods: 68 endoscopic stent implantations were performed in 64 patients (15 female and 49 male) with malignant dysphagia between 2003 and 2008. After radiological investigations, distally deployed covered stents with or without an antireflux valve were placed, depending on the localization of the tumour. In one patient with a stenosis localized in the upper third of the oesophagus a proximally deployed covered stent was used. The aim was to re-establish oral nutrition and cover possible fistulas., Results: Significant improvement of swallowing was detected in every patient. Average dysphagia score has improved from 3.2 to 1.7. Technical difficulties during stenting occurred in a relatively low percentage of patients only (2 in 68; i.e. 2.94%). Fistulas were covered in every case. Early stent migration (<7 days) happened in one case. One patient suffered non-fatal myocardial infarction two days after stent placement. In 5 cases tumour in- and overgrowth, in 4 cases bleeding was seen as late complications. Oesophago-tracheal fistula was noted in three patients after stent implantation. Late stent migration (>7 days) occurred in two patients. Re-stenting was necessary in four cases, while three patients needed an upper GI endoscopy for cleansing the stent caused by food obstruction., Conclusions: According to our data self-expanding metal stents are highly effective and safe for improving dysphagia. Stent-related complications are relatively rare. This method is highly recommended for palliation of malignant dysphagia.
