The Role of Statins on Helicobacter pylori Eradication: Results from the European Registry on the Management of H. pylori (Hp-EuReg).

Statins could increase the effectiveness of Helicobacter pylori eradication therapies due to their anti-inflammatory effect. The aim of this study was to analyze the impact of this therapeutic association in real life. This is a multicenter, prospective, non-interventional study aimed at evaluating the management of H. pylori by European gastroenterologists. Patients were registered in an e-CRF by AEG-REDCap from 2013 to 2020. The association between statin use and H. pylori eradication effectiveness was evaluated through multivariate analysis. Overall, 9988 and 705 patients received empirical and culture-guided treatment, respectively. Overall, statin use was associated with higher effectiveness in the empirical group (OR = 1.3; 95%CI = 1.1-1.5), but no association was found with first-line treatment effectiveness (N = 7738); as an exception, statin use was specifically associated with lower effectiveness of standard triple therapy (OR = 0.76; 95%CI = 0.59-0.99). In the rescue therapy empirical group (N = 2228), statins were associated with higher overall effectiveness (OR = 1.9; 95%CI = 1.4-2.6). However, sub-analyses by treatment schemes only confirmed this association for the single-capsule bismuth quadruple therapy (OR = 2.8; 95%CI = 1.3-5.7). No consistent association was found between statin use and H. pylori therapy effectiveness. Therefore, the addition of statins to the usual H. pylori treatment cannot be currently recommended to improve cure rates.

European Registry on Helicobacter pylori Management: Effectiveness of First and Second-Line Treatment in Spain.

The management of Helicobacter pylori infection has to rely on previous local effectiveness due to the geographical variability of antibiotic resistance. The aim of this study was to evaluate the effectiveness of first and second-line H. pylori treatment in Spain, where the empirical prescription is recommended. A multicentre prospective non-interventional registry of the clinical practice of European gastroenterologists concerning H. pylori infection (Hp-EuReg) was developed, including patients from 2013 until June 2019. Effectiveness was evaluated descriptively and through a multivariate analysis concerning age, gender, presence of ulcer, proton-pump inhibitor (PPI) dose, therapy duration and compliance. Overall, 53 Spanish hospitals were included, and 10,267 patients received a first-line therapy. The best results were obtained with the 10-day bismuth single-capsule therapy (95% cure rate by intention-to-treat) and with both the 14-day bismuth-clarithromycin quadruple (PPI-bismuth-clarithromycin-amoxicillin, 91%) and the 14-day non-bismuth quadruple concomitant (PPI-clarithromycin-amoxicillin-metronidazole, 92%) therapies. Second-line therapies were prescribed to 2448 patients, with most-effective therapies being the triple quinolone (PPI-amoxicillin-levofloxacin/moxifloxacin) and the bismuth-levofloxacin quadruple schemes (PPI-bismuth-levofloxacin-amoxicillin) prescribed for 14 days (92%, 89% and 90% effectiveness, respectively), and the bismuth single-capsule (10 days, 88.5%). Compliance, longer duration and higher acid inhibition were associated with higher effectiveness. "Optimized" H. pylori therapies achieve over 90% success in Spain.

Screening for latent tuberculosis infection in patients with inflammatory bowel disease: Can interferon-gamma release assays replace the tuberculin skin test?

BACKGROUND/AIMS: Screening for latent tuberculosis infection is mandatory before starting anti-tumor necrosis factor therapy. New assays based on interferon-γ (IFN-γ) release have recently become available and may be more accurate. The aim of this study was to compare QuantiFERON-TB and tuberculin skin test in screening for latent infection in patients with inflammatory bowel disease. MATERIALS AND METHODS: We prospectively screened 138 patients with inflammatory bowel disease for latent tuberculosis infection with chest X-ray, tuberculin skin test, and a third-generation QuantiFERON-TB test. The association of the results in both tests with immunosuppression or inflammatory activity was determined by logistic regression. RESULTS: The tuberculin skin test and QuantiFERON-TB were positive in 21.7% and 24.6% of the patients, respectively. Overall, 71% patients were receiving immunosuppressants. Concordance between the two tests was moderate (κ=0.59; 95% confidence interval (CI), 0.43-0.75) and was higher in immunosuppressant-naïve patients (κ=0.75; 95% CI, 0.52-0.97) than in immunosuppressed patients (κ=0.51; 95% CI, 0.30-0.72). In both the tests, disease activity and receiving immunosuppression were not associated with the test results. Nevertheless, QuantiFERON-TB was negatively influenced with two or more immunosuppressive drugs. CONCLUSION: Concordance between the two tests was moderate, and it appears lower with immunosuppression. QuantiFERON-TB alone may be appropriate in immunosuppressant-naïve patients. Both tests should be considered in immunosuppressed patients.

The utility of faecal calprotectin to predict post-operative recurrence in Crohns disease.

OBJECTIVE: Endoscopic recurrence in Crohns disease occurs in up to 80% of patients during the first year after surgery. Due to this, these patients need close monitoring. Faecal calprotectin has been proposed to be used as a non-invasive marker to monitor inflammatory activity. Up to now the use of faecal markers in endoscopic recurrence has been scarcely studied and with contradictory results. MATERIAL AND METHODS: This was a cross-sectional observational study of diagnostic validity. It included all patients with Crohns disease (CD) and ileocolic resection retrospectively who had had an ileocolonoscopy and a determination of faecal calprotectin before this colonoscopy, from 2007 to 2015. RESULTS: Ninety-seven patients were included. We observed that the mean value of faecal calprotectin increased as the Rutgeerts score increased. The variable of that most statistical significance obtained in bivariate analysis was faecal calprotectin (p < 0.0001). Area under curve (AUC) of faecal calprotectin in endoscopic recurrence was 0.74 (95% CI: 0.644-0.842), and an optimal cut-off of 60 mcrgr/gr, obtained a score of 0.45 using Youden test. This indicated that calprotectin would have 88% Sensitivity and 58% Specificity in detecting any recurrence, the NPV was approximately 83,9%. None of the other variables studied had a significant correlation. CONCLUSION: Faecal calprotectin predicts endoscopic recurrence in CD patients who have gone through surgery, however the cut-off point is still a problem so we cannot recommend calprotectin as a substitute of colonoscopy for CD monitoring and treatment adjustment.

Ovesco system for treatment of postpolypectomy bleeding after failure of conventional treatment.

The clip Ovesco (Ovesco, Tübingen, Germany) is a novel endoscopic method for mechanical compression of tissue in the gastrointestinal tract. The indications for treatment are closure of perforations and fistulas and control of bleeding in which the conventional endoscopic treatment has failed. We report two cases about the use of an Ovesco (over-the-scope clip, OTSC) system to control persistent bleeding postpolypectomy after failure of usual treatment.

Clipping for endoscopic perforations: initial success but late complication requiring surgery.

INTRODUCTION: This response discusses the article by Kim and colleagues entitled "endoscopic clip closure versus surgery for the treatment of iatrogenic colon perforations developed during diagnostic colonoscopy: a review of 115,285 patients". Iatrogenic colonoscopic perforation, although uncommon, implies serious management problems for endoscopists and surgeons. Nonoperative treatment currently is recommended under certain conditions, and endoscopic clips can primarily close iatrogenic perforations, helping to avoid surgery. Of the 27 colonoscopic perforation cases presented in the article by Kim and colleagues, 16 were managed by endoscopic clipping closure and 11 by primary surgery. Conservative treatment failed for three patients. Only perforation size obtained statistical significance among the nine variables contrasted between the 11 cases with primary surgery and the 13 cases with successful endoscopic clipping. The results for the three patients whose endoscopic closure failed are not reported. AUTHORS' OPINION: The authors of this letter think it would have been interesting if these three patients had been included in the analysis due to the high importance of discovering factors that can predict failure of endoscopic clipping for perforations. CONCLUSIONS: To call attention to possible late complications requiring surgery even when initial conservative management of endoscopic perforation succeeds, the authors of this letter present a case of a colocutaneous (actually, sigmoid-scrotal) fistula in a patient 2 weeks after an apparently successful closure of colonoscopic perforation with an "over-the-scope" clip.

Diffuse intestinal ganglioneuromatosis an uncommon manifestation of Cowden syndrome.

Diffuse intestinal ganglioneuromatosis is a hamartomatous polyposis characterized by a disseminated, intramural or transmural proliferation of neural elements involving the enteric plexuses. It has been associated with MEN II, neurofibromatosis type 1 and hamartomatous polyposis associated with phosphatase and tensin homolog mutation. We report the case of a female patient with a history of a breast and endometrial tumor who presented in a colonoscopy performed for rectal bleeding diffuse ganglioneuromatosis, which oriented the search for other characteristic findings of Cowden syndrome given the personal history of the patient. The presence of an esophagogastric polyposis was also noted. Cowden syndrome is characterized by skin lesions, but it is rarely diagnosed by these lesions, because they are usually overlooked. Intestinal polyposis is not a major diagnostic criterion but it is very useful for early diagnosis. The combination of colonic polyposis and glucogenic acanthosis should orient the diagnosis to Cowden syndrome.
