Background and study aims Telemedicine has progressed significantly in recent years, with newer, more integrated information technology systems improving healthcare delivery. The development of the world’s first cloud-based capsule platform could allow safe and timely virtual analysis of videos from a network of linked hospital centers. We aimed to assess the efficacy of Medtronic’s PillCam Remote Reader System. Methods PillCam remote reader technical data were collected from the capsule endoscopy (CE) database over 8 months. User-reported performance was collect using an online survey. Outcomes included overall procedure success, video-upload/report-download rates and speeds, encryption/decryption rates, and user/reader satisfaction. Results Data from 377 studies encompassing seven different readers was collected (318 small bowel capsules, 59 colon capsules). Overall procedure success was 100% (all videos reported). Two upload delays occurred (< 24 hours). There were no encryption/decryption errors. Seven of seven respondents felt it easy to access and use vs one of seve for the old system. Six of seven respondents felt department efficiency increased. Benefits included off-site reading and multisite-conferences. Issues included offsite difficulty accessing other hospital systems. Conclusions PillCam remote reader is a reliable, secure, and effective capsule analysis platform and should be incorporated into any CE service development plan.

Background: Local audits of Helicobacter pylori (H. pylori) prescriptions and outcomes are necessary to assess guideline awareness among clinicians and treatment effectiveness. Aims: The aims were to investigate first-line prescriptions and effectiveness over a 10-year period in Ireland and evaluate the influence of the 2017 Irish consensus guidelines on these trends. Methods: Data were collected at e-CRF AEG-REDCap from the European Registry on H. pylori management (Hp-EuReg) and quality reviewed from 2013 to 2022. All treatment-naïve cases were assessed for effectiveness by modified intention-to-treat (mITT) analysis. Multivariate analysis was also performed. Results: Data from 1000 patients (mean age 50 ± 15 years; 54% female) were analyzed. Clarithromycin (C) and amoxicillin (A) triple therapy represented 88% of treatments, followed by sequential C, A, and metronidazole (M) therapy (4.3%) and triple C + M (2.7%). Bismuth quadruple therapy was prescribed in 1.7% of cases. Treatment durations of 14, 10, and 7 days accounted for 87%, 4.5%, and 8.5% of prescriptions, respectively. High-, standard-, and low-dose proton pump inhibitors (PPIs; 80 mg, 40 mg, and 20 mg omeprazole equivalent b.i.d.) were used in 86%, 0.9%, and 13% of cases, respectively. The overall eradication rate was 80%, while it was 81% for triple C + A. Good compliance and high-dose PPI were associated with higher overall mITT eradication rates (OR 4.5 and OR 1.9, respectively) and triple C + A eradication rates (OR 4.2 and OR 1.9, respectively). Overall eradication rates increased from 74% pre-2017 to 82% (p < 0.05) by the end of 2022. Similarly, the triple C + A eradication rates increased from 76% to 83% (p < 0.05). Conclusions: While first-line treatment effectiveness improved in clinical practice over time, cure rates remain below 90%. Alternative first-line strategies are required in Ireland.

Background: CCE is a diagnostic tool lacking clinical data on false negative rates. We aimed to assess this rate and the reader/technical error breakdown. Methods: False negative CCEs were identified after comparing to a colonoscopy database. Missed pathology characteristics and study indications/quality were collated. Cases were re-read by experts and newly identified lesions/pathologies were verified by an expert panel and categorised as reader/technical errors. Results: Of 532 CCEs, 203 had an adequately reported comparative colonoscopy, 45 (22.2%) had missed polyps, and 26/45 (57.8%) reached the colonic section with missed pathology. Of the cases, 22 (84.6%) had adequate bowel preparation. Indications included 13 (50%) polyp surveillance, 12 (46%) GI symptoms, 1 (4%) polyp screening. CCE missed 18 (69.2%) diminutive polyps and 8 (30.8%) polyps ≥ 6 mm, 18/26 (69.2%) of these were adenomas. Excluding incomplete CCE correlates, colonoscopy total and significant polyp yield were 97/184 (52.7%) and 50/97 (51.5%), respectively. CCE total polyp and significant polyp false negative rate was 26.8% (26/97) and 16% (8/50), respectively. Following re-reading, reader and technical error was 20/26 (76.9%) and 6/26 (23.1%). Total and significant missed polyp rates were 20.6% (20/97) and 14% (7/50) for reader error, 6.2% (6/97) and 2% (1/50) for technical error. Conclusions: False negative CCE rate is not insubstantial and should be factored into clinical decision making.

Helicobacter pylori (H. pylori) eradication rates have fallen globally, likely in large part due to increasing antibiotic resistance to traditional therapy. In areas of high clarithromycin and metronidazole resistance such as ours, Maastricht VI guidelines suggest high dose amoxicillin dual therapy (HDADT) can be considered, subject to evidence for local efficacy. In this study we assess efficacy of HDADT therapy for H. pylori eradication in an Irish cohort. To assess the efficacy of HDADT therapy for H. pylori eradication in an Irish cohort as both first line, and subsequent therapy for patients diagnosed with H. pylori. All patients testing positive for H. pylori in a tertiary centre were treated pro spectively with HDADT (amoxicillin 1 g tid and esomeprazole 40 mg bid × 14 d) over a period of 8 months. Eradication was confirmed with Urea Breath Test at least 4 wk after cessation of therapy. A delta-over-baseline > 4% was considered positive. Patient demographics and treatment outcomes were recorded, analysed and controlled for basic demographics and prior H. pylori treatment. One hundred and ninety-eight patients were identified with H. pylori infection, 10 patients were excluded due to penicillin allergy and 38 patients refused follow up testing. In all 139 were included in the analysis, 55% (n = 76) were female, mean age was 46.6 years. Overall, 93 (67%) of patients were treatment-naïve and 46 (33%) had received at least one previous course of treatment. The groups were statistically similar. Self-reported compliance with HDADT was 97%, mild side-effects occurred in 7%. There were no serious adverse drug reactions. Overall the eradication rate for our cohort was 56% (78/139). Eradication rates were worse for those with previous treatment [43% (20/46) vs 62% (58/93), P = 0.0458, odds ratio = 2.15]. Age and Gender had no effect on eradication status. Overall eradication rates with HDADT were disappointing. Despite being a simple and possibly better tolerated regime, these results do not support its routine use in a high dual resistance country. Further investigation of other regimens to achieve the > 90% eradication target is needed.

Background: There has been a reduction in successful H. pylori eradication rates recently, which is largely attributed to increasing antibiotic resistance. In areas of high dual clarithromycin and metronidazole resistance such as ours, Maastricht VI/Florence guidelines recommend bismuth quadruple therapy (BQT) as first line of therapy; however, the availability of bismuth was poor in Ireland until recently. Similarly, tetracycline, a component of BQT, is restricted locally, with doxycycline (D) being approved and reimbursed for most indications. Aims: To assess the efficacy of BQT-D therapy for H. pylori eradication in an Irish cohort. Methods: All patients testing positive for H. pylori in three Irish referral centres by urea breath test, stool antigen, or histology were treated prospectively with BQT-D (bismuth subcitrate 120 mg QDS, metronidazole 400 mg TDS, doxycycline 100 mg BD and esomeprazole 40 mg BD) for 14 days. Eradication was evaluated with a urea breath test (UBT) >4 weeks after therapy cessation or by stool antigen testing, as available. Outcomes were recorded and analysed according to demographics and H. pylori treatment history of the patients. Results: 217 patients completed post-eradication testing. Of which, 124 (57%) were female, with a mean age 52 years. 180 patients (83%) were treatment-naïve. A total of 165/180 (92%) of the treatment-naïve patients had successful eradication. There was no association between eradication and gender or age in this cohort (p = 0.3091, p = 0.962 respectively). A total of 29 patients received this therapy as second-line therapy, of which 22 (76%) had successful eradication. Eight patients received the regimen as rescue therapy, with seven (88%) having successful eradication. No serious adverse events were reported. Eleven individuals (6.5%) commented on the complicated nature of the regimen, with 11 tablets being taken at five intervals daily. Conclusions: BQT-D as first-line therapy for H. pylori infection is highly effective in a high dual-resistance population, achieving >90% eradication. BQT-D as a second-line treatment performed less well. Our data support BQT-D as a first-line treatment.
