[Effects of SARS-CoV-2 Infection on Symptoms and Therapy of Inflammatory Bowel Disease]. / Auswirkungen einer SARS-CoV-2-Infektion auf Symptomatik und Therapie chronisch-entzündlicher Darmerkrankungen.

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 (1.6 %) were tested for SARS-CoV-2 infection because of abdominal symptoms. In the course of COVID-19 disease, 43.5 % developed diarrhea, abdominal pain or hematochezia (risk of hospitalization with vs. without abdominal symptoms: 20.0 % vs. 10.6 %, p < 0.01). With active IBD at the time of SARS-CoV-2 detection, there was an increased risk of hospitalization (remission 11.2 %, active IBD 23.3 % p < 0.05). IBD-specific therapy remained unchanged in 115 patients (71.4 %); the most common change was an interruption of systemic therapy (16.2 %). DISCUSSION: New abdominal symptoms often appeared in SARS-CoV-2 infected IBD patients. However, these only rarely led to SARS-CoV-2 testing. A high IBD activity at the time of SARS-CoV-2 detection was associated with an increased risk of hospitalization.

Integrating the Patient Perspective to Validate a Measure of Disease Severity in Inflammatory Bowel Disease: Online Survey of Patients and Their Physicians.

BACKGROUND: The patient perspective is essential for assessing disease severity, but it is not always adequately considered. We describe how a comprehensive clinical disease severity index (DSI) for inflammatory bowel disease (IBD) correlates with patient global self-assessment (PGSA). METHODS: In an individually linked parallel online survey, physicians provided the DSI, and patients provided self-assessed severity using a global question and visual analog scale (0-100) (PGSA). Mean DSI values by PGSA were calculated with 95% confidence intervals. Pearson correlation (r) and the intraclass correlation coefficient were calculated for PGSA vs DSI. Positive predictive values for identifying severe disease with PGSA categories as a reference were based on a threshold >22 points. RESULTS: The primary analysis included 89 pairs (46 Crohn's disease [CD], 43 ulcerative colitis [UC]) with strict criteria and 147 pairs when less stringent. Common reasons for exclusion were missing values for albumin or colonoscopy. Mean DSI values showed no clear trend with increasing PGSA in CD but good discrimination between moderate, severe, and very severe PGSA in UC. For PGSA on the visual analog scale, r was 0.54 for CD and 0.59 for UC (difference in means: CD 27.7, UC 13.8; intraclass correlation coefficient: CD 0.48, UC 0.58). A high DSI predicted severe disease in 76.2% of CD and 65.2% of UC. CONCLUSIONS: The DSI showed good discrimination for patient-reported disease severity in UC but performed unsatisfactorily in CD. Correlations were moderate. Further refinement of the DSI is suggested to better reflect the patient perspective.

The performance of an inflammatory bowel disease severity score was compared with self-perceived severity based on an individually linked online survey of patients and their physicians. Agreement and prediction of severe disease were moderate and should be improved by integrating the patients' perspective.

One-week once-daily triple therapy with esomeprazole, moxifloxacin, and rifabutin for eradication of persistent Helicobacter pylori resistant to both metronidazole and clarithromycin.

AIM: To investigate a 1-week once-daily triple therapy with esomeprazole, moxifloxacin, and rifabutin for rescue therapy of Helicobacter pylori infection. METHODS: Consecutive patients (n = 103) with at least one previous treatment failure and H. pylori infection resistant to both metronidazole and clarithromycin were treated with esomeprazole 40 mg, moxifloxacin 400 mg, and rifabutin 300 mg, given once daily for 7 days. Eradication was confirmed by histology and culture. CYP2C19 status was determined by polymerase chain reaction-restriction fragment length polymorphism. RESULTS: Intention-to-treat and per-protocol eradication rates were 77.7% (68.4-85.3) and 83.3% (74.4-90.2). Five patients discontinued prematurely (4.8%). Eradication was achieved in 93.1% of poor/intermediate metabolizers and in 78.8% of homozygous extensive metabolizers (p = .14). Eradication rates in patients with one, two, three, and four or more previous failures were 78.3%, 89.6%, 68.6%, and 88.9%, respectively (p = .21). The regimen was effective in seven of nine patients who previously failed quadruple therapy. Post-treatment resistance to moxifloxacin and rifabutin was detected in two (12.5%) and five (31%) patients after treatment failure. CONCLUSION: Once-daily triple therapy with esomeprazole, moxifloxacin, and rifabutin is a promising, safe, and convenient regimen for rescue therapy of H. pylori infection that may serve as a valuable alternative to quadruple therapy, particularly for patients with intolerance to amoxicillin.

Boswellia serrata extract for the treatment of collagenous colitis. A double-blind, randomized, placebo-controlled, multicenter trial.

BACKGROUND AND AIMS: The objective of this study was to investigate the effect of Boswellia serrata extract (BSE) on symptoms, quality of life, and histology in patients with collagenous colitis. MATERIALS AND METHODS: Patients with chronic diarrhea and histologically proven collagenous colitis were randomized to receive either oral BSE 400 mg three times daily for 6 weeks or placebo. Complete colonoscopy and histology were performed before and after treatment. Clinical symptoms and quality of life were assessed by standardized questionnaires and SF-36. The primary endpoint was the percentage of patients with clinical remission after 6 weeks (stool frequency

7-day triple therapy of Helicobacter pylori infection with levofloxacin, amoxicillin, and high-dose esomeprazole in patients with known antimicrobial sensitivity.

BACKGROUND AND AIMS: Failed primary anti-Helicobacter pylori therapy results in a high rate of antimicrobial resistance. This necessitates a search for new regimens to cure H. pylori infection. The aim of this study was to evaluate the efficacy and tolerability of a new levofloxacin-containing 7-day triple therapy and to compare it with that of standard French triple therapy in patients with known H. pylori susceptibility to MET (metronidazole) and CLA (clarithromycin). PATIENTS AND METHODS: Sixty-one patients with documented antibiotic sensitivity (E-test) and an indication for anti-H. pylori treatment based on the Maastricht Consensus 2/2000 guidelines were randomized to receive either esomeprazole 2 x 40 mg, levofloxacin 2 x 500 mg, and amoxicillin 2 x 1 g for 7 days (ELA, n = 30), or esomeprazole 2 x 20 mg, clarithromycin 2 x 500 mg, and amoxicillin 2 x 1 g for 7 days (ECA, n = 31). A cure check was performed 4-6 weeks after conclusion of therapy. RESULTS: Sixty-one patients were randomized to the two treatment groups. Twenty-eight of 30 patients of the ELA group were available for per-protocol (PP) analysis, of whom 26 (92.9% CI: 76-99%; intention-to-treat [ITT] analysis 86.7% CI: 68-96%) became H. pylori negative compared with 26 of the 31 patients of the ECA group (83.9%, CI: 66-93% both PP and ITT analyses). Five patients of the ELA group showed CLA resistance, three of whom also showed MET resistance, and all five were treated successfully. Two patients with levofloxacin-resistant strains, one in each group, were cured. Both regimens were generally well tolerated with minor adverse events being seen in 15 patients (51.7%) of the ELA group and in 13 (40.6%) of the ECA group. None of the patients discontinued treatment prematurely due to adverse events. CONCLUSION: The data of this pilot study suggest a better than 80% efficacy of the new 7-day levofloxacin triple therapy, which is within the range of the French triple therapy in patients with MET- and CLA-susceptible strains. The data suggest that the new levofloxacin triple therapy may also be an option in patients with MET- and CLA-resistant H. pylori strains.

Oral budesonide therapy improves quality of life in patients with collagenous colitis.

INTRODUCTION: Collagenous colitis is an idiopathic microscopic colitis characterised by watery diarrhoea. The impact of collagenous colitis on quality of life has not been assessed. Our aim was to assess quality of life in patients with this condition and compare the effect of treatment with budesonide capsules or placebo on this parameter. METHODS: Patients with chronic diarrhoea and histologically-proven collagenous colitis were randomised to receive either budesonide controlled-release capsules (Entocort capsules, AstraZeneca, Lund, Sweden), 9 mg/day, or placebo for 6 weeks. Quality of life was measured using the validated Gastrointestinal Quality of Life Index (GIQLI) at baseline and after 6 weeks. With the GIQLI, scores range from 0 to 144, with higher scores representing better quality of life. RESULTS: Complete quality of life assessment was available in 29 patients (budesonide: n=17; placebo: n=12). At baseline, quality of life was low in patients with collagenous colitis (mean 76). After 6 weeks of treatment, the mean GIQLI score increased significantly in the budesonide group (from 67 to 92, p<0.001), but remained unchanged in the placebo group (86-88). The mean score of the dimensions symptoms (p=0.001), emotional functioning (p=0.003) and physical functioning (p=0.017) increased significantly in the budesonide group compared with the placebo group. A significantly larger proportion of patients in the budesonide group experienced improved stool consistency (p<0.01) and a significant reduction in the mean stool frequency compared with those in the placebo group (p<0.01). CONCLUSION: Quality of life is seriously reduced in patients with collagenous colitis. Six-week treatment with oral budesonide controlled-release capsules significantly improves quality of life and clinical symptoms compared with placebo in these patients.

A prospective, randomized study of quadruple therapy and high-dose dual therapy for treatment of Helicobacter pylori resistant to both metronidazole and clarithromycin.

BACKGROUND AND AIM: Failure of primary anti-H. pylori therapy results in a high rate of antimicrobial resistance. Here, we investigated the efficacy of high-dose dual therapy and quadruple therapy as salvage treatments for eradication of H. pylori resistant to both metronidazole and clarithromycin. PATIENTS AND METHODS: Patients with at least one treatment failure and infected with H. pylori resistant to both metronidazole and clarithromycin, were randomized to receive either omeprazole 4 x 40 mg and amoxicillin 4 x 750 mg; or omeprazole 2 x 20 mg, bismuthcitrate 4 x 107 mg, metronidazole 4 x 500 mg and tetracycline 4 x 500 mg. Both regimens were given for 14 days. In cases of persistent infection, a cross-over therapy was performed. RESULTS: Eighty-four patients were randomized. Cure of H. pylori infection was achieved in 31 patients after dual therapy and in 35 patients after quadruple therapy (per protocol: 83.8% (95% CI, 67.9-93.8) and 92.1% (95% CI, 78.6-98.3), respectively (p=0.71); intention to treat: 75.6% (95% CI: 59.7-87.6) and 81.4% (95% CI: 66.6-91.6), respectively (p=0.60)). Cross-over therapy was performed in six of nine patients, four of whom were cured of the infection. CONCLUSION: Both high-dose dual therapy and quadruple therapy are effective in curing H. pylori infection resistant to both metronidazole and clarithromycin in patients who experienced previous treatment failures.

Budesonide treatment for collagenous colitis: a randomized, double-blind, placebo-controlled, multicenter trial.

BACKGROUND & AIMS: Collagenous colitis is an idiopathic microscopic colitis characterized by chronic watery diarrhea, a typical subepithelial collagen layer, and lymphoplasmacellular infiltration. We investigated the effect of budesonide on symptoms and histology in patients with collagenous colitis in a randomized, double-blind, placebo-controlled multicenter trial. METHODS: Patients with chronic diarrhea and histologically proven collagenous colitis were randomized to receive either oral budesonide (Entocort capsules; AstraZeneca, Sodertalje, Sweden) 9 mg/day for 6 weeks or placebo. Complete colonoscopy was performed before and after treatment. Histopathology was assessed by a single pathologist blinded to the patients' treatment. Clinical symptoms were assessed by standardized questionnaires. RESULTS: Fifty-one patients were randomized; 45 patients were available for per protocol analysis. The rate of clinical remission was significantly higher (P < 0.001) in the budesonide group than in the placebo group (per protocol 86.9% vs. 13.6%, respectively; intention-to-treat 76.9% vs. 12.0%, respectively). Histologic improvement was observed in 14 patients of the budesonide group (60.9%) and in 1 patient of the placebo group (4.5%; P < 0.001). Two patients in the budesonide group (7.7%) and 1 patient in the placebo group (4.0%) discontinued treatment prematurely because of side effects. CONCLUSIONS: Oral budesonide (Entocort capsules) is an effective and safe treatment modality for patients with collagenous colitis. Long-term follow-up of these patients is necessary to investigate whether clinical and histologic remission is sustained.
