Introduction: We sought to evaluate the effect of proton pump inhibitor (PPI) use on the development and severity of iron deficiency anemia (IDA) in celiac disease (CD).

Methods: We conducted a retrospective chart review of patients older than 18 years of age at Milton S. Hershey Medical Center who were diagnosed with CD. We analyzed four cohorts of celiac patients: (1) IDA diagnosis with PPI usage, (2) no IDA diagnosis with PPI usage, (3) IDA diagnosis with no PPI usage, and (4) no IDA diagnosis with no PPI usage. We also stratified celiac patients with IDA by anemia severity.

Results: Of 366 celiac patients, 92 (25.1%) were diagnosed with IDA, of which 60 (65.2%) were on a PPI. The mean Hgb of celiac patients with IDA on a PPI was 11.1 g/dL and 12.1 g/dL for those without PPI (p = 0.04). For all celiac patients on a PPI without IDA, the mean was 13.3 g/dL and 13.7 g/dL for those without PPI (p = 0.02). PPI use occurred in 12 (70.6%) of the 17 patients with low severity anemia, 11 (64.7%) of the 17 patients with medium severity and 6 (85.7%) of the 7 patients with severe (p = 0.55).

Conclusions: There is significant association between PPI use and IDA in celiac patients (p < 0.0001). Of those with IDA on PPIs, the distribution of the severity of anemia is not statistically different compared to those not on PPI. Discontinuation of PPIs or usage of alternative acid suppressive treatments may be indicated in patients with CD and iron deficiency anemia.

Introduction: Celiac disease is an autoimmune condition that affects approximately 1% of the population worldwide. Although its main impact often concerns the small intestine, resulting in villous atrophy and nutrient malabsorption, it can also cause systemic manifestations, particularly when undiagnosed or left untreated.

Method: Attention is directed to the possible psychological, psychiatric, and organic brain manifestations of celiac disease. Specific topics related to the influence and risk of such manifestations with respect to celiac disease are defined and discussed. Overall, eighteen main topics are considered, sifted from over 500 references.

Results: The most often studied topics were found to be the effect on quality of life, organic brain dysfunction and ataxia, epilepsy, Down syndrome, generalized psychological disorders, eating dysfunction, depression, and schizophrenia. For most every topic, although many studies report a connection to celiac disease, there are often one or more contrary studies and opinions. A bibliographic analysis of the cited articles was also done. There has been a sharp increase in interest in this research since 1990. Recently published articles tend to receive more referencing, up to as many as 15 citations per year, suggesting an increasing impact of the topics. The number of manuscript pages per article has also tended to increase, up to as many as 12 pages. The impact factor of the publishing journal has remained level over the years.

Conclusion: This compendium may be useful in developing a consensus regarding psychological, psychiatric, and organic brain manifestations that can occur in celiac disease and for determining the best direction for ongoing research focus.

Introduction: Celiac disease (CD) is a chronic immune-mediated disorder triggered by gluten ingestion in genetically predisposed individuals. Historically, CD was primarily recognized and described as a disease of the Caucasian population. Data from a national survey in 2015 revealed that 0.79% of the population was formally diagnosed with celiac disease, with the non-Hispanic white population having a prevalence of 4-8 times higher than other underrepresented races. Although there is evidence that CD affects minorities at higher than reported rates, there is little data on its effects on minority populations. Our study aimed to characterize celiac-related complications among underrepresented populations in a large health database.

Methods: We performed a cohort study among patients aged ≥18, utilizing the TriNetX US Collaborative Network. Two cohorts of patients (minority and non-Hispanic white) with CD were identified between 2016 and 2021. Cohorts were propensity scores matched on demographics and baseline clinical characteristics. Outcomes were assessed up to 1 year after the index event (CD diagnosis), including vitamin/mineral deficiencies and hospital visits. Data were analyzed using the TriNetX Analytics function.

Results: Each group was matched with 817 patients. Compared to the non-Hispanic white population, the minority group had a similar incidence of iron, vitamin B, and zinc deficiencies. The minority group had a higher risk of vitamin D deficiency, anemia secondary to iron deficiency, inpatient hospital stays, and emergency department visits.

Conclusion: Our results indicate that minority patients with celiac disease have a higher incidence of vitamin D and iron deficiency.

Introduction: Evidence for the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) between a basket catheter and a balloon catheter for endoscopic common bile duct stone (CBDS) removal is lacking. This study aimed to compare ERCP outcomes using a basket catheter and a balloon catheter for endoscopic CBDS removal.

Methods: This multicenter retrospective study included 904 consecutive patients with native papilla who underwent endoscopic stone removal for CBDS ≤10 mm using a basket catheter and/or a balloon catheter at three institutions in Japan. ERCP outcomes between the basket and balloon groups were compared using inverse probability of treatment weighting (IPTW) method.

Results: ERCP-related adverse events occurred in 6.5% (29/449) and 7.7% (35/455) of patients in the basket and balloon groups, respectively (IPTW-adjusted p = 0.52). The incidences of post-ERCP pancreatitis, cholangitis, and perforation were similar in the basket and balloon groups (3.8% vs. 2.9%, 1.3% vs. 0.9%, and 0.7% vs. 0.7%, respectively). However, bleeding incidences were significantly higher in the balloon group than in the basket group (3.3% vs. 0.7%, IPTW-adjusted p = 0.012). Successful complete stone removal at one ERCP session using a single catheter was achieved in 17.8% (80/449) in the basket group and in 81.3% (370/455) in the balloon group (IPTW-adjusted p < 0.001).

Discussion: A balloon catheter is more likely to complete stone extraction for CBDS ≤10 mm with a single catheter at one endoscopic stone removal session. However, the risk for post-ERCP bleeding is higher in the balloon group than in the basket group.

Background: High-quality colonoscopic surveillance can lead to earlier and increased detection of colorectal neoplasia in patients with inflammatory bowel disease (IBD). In IBD clinical trials, endoscopy is used to assess mucosal disease activity before and after treatment but also provides an opportunity to surveil for colorectal neoplasia during follow-up.

Summary: Best practices for colorectal cancer identification in IBD clinical trials require engagement and collaboration between the clinical trial sponsor, site endoscopist and/or principal investigator, and central read team. Each team member has unique responsibilities for maximizing dysplasia detection in IBD trials.

Key messages: Sponsors should work in accordance with scientific guidelines to standardize imaging procedures, design the protocol to ensure the trial population is safeguarded, and oversee trial conduct. The site endoscopist should remain updated on best practices to tailor sponsor protocol-required procedures to patient needs, examine the mucosa for disease activity and potential dysplasia during all procedures, and provide optimal procedure videos for central read analysis. Central readers may detect dysplasia or colorectal cancer and a framework to report these findings to trial sponsors is essential. Synergistic relationships between all team members in IBD clinical trials provide an important opportunity for extended endoscopic evaluation and colorectal neoplasia identification.

Introduction: Chronic pancreatitis (CP) is a relevant chronic medical problem whereby delayed presentation and poor patient understanding can cause adverse effects. Quality of patient information available on the internet about CP is not known.

Methods: A systematic review of the information about CP available online using the search term "chronic pancreatitis" in using the search engine Google has been conducted. The quality of the top 100 websites returned from this search term was analysed using the validated Ensuring Quality Information for Patients (EQIP) tool (maximum score 36). Additional items were included in the website analysis specific to CP.

Results: In total, 45 websites were eligible for analysis. The median EQIP score of the websites was 16 (interquartile range 12-19.5). The majority of websites originated from the USA and the United Kingdom with 31 and 11 websites, respectively. Provision of additional information was inconsistent, with most websites covering information regarding aetiology and advocating alcohol and tobacco cessation, but only few reporting on more complex issues.

Conclusion: Internet available information about CP is of limited quality. There is an immediate need for high quality, patient targeted, and informative literature accessible on the internet about this topic.

Background: Palliative care patients frequently present with clinically significant gastrointestinal bleeding. Due to the existence of confounding comorbidities and a remarkably reduced state of general health in many cases, the management of gastrointestinal bleeding in this population is often challenging.

Summary: This review summarizes and discusses the role of thalidomide in gastrointestinal bleeding with a special focus on palliative care patients. In addition, an illustrative case report is presented. Thalidomide may be beneficial in gastrointestinal bleeding by exerting antiangiogenic effects. The drug has an acceptable safety profile. Side effects like neurotoxicity may limit its use but can be monitored safely. Due to thalidomide's thrombin generation potential, patients managed with thalidomide-containing regimes should be closely monitored for deep venous thrombosis. Given its teratogenicity, thalidomide should not be administered to women of childbearing potential who are not using adequate contraception.

Key message: Physicians caring for patients in a palliative care setting should be aware of thalidomide as an effective therapeutic option when endoscopy fails to find a bleeding source or for those patients who cannot or refuse to undergo endoscopy but present with recurrent or obscure gastrointestinal bleeding.

Introduction: Recently, the detection of superficial non-ampullary duodenal epithelial tumors (SNADETs) including adenomas and superficial duodenal carcinomas has increased. Various endoscopic treatment methods have also been reported for SNADETs, but there are few reports on the natural history. The aim of this study was to analyze factors related to tumor growth and determine the characteristics of SNADETs which need early therapeutic intervention.

Methods: A single-center, retrospective study was performed on the medical records of 309 patients with SNADETs who underwent endoscopic or surgical resection between January 2010 and May 2021. Of these, 41 patients who were followed up for more than 1 year by endoscopy were analyzed. The primary outcome was an analysis of the tumor growth speed. Secondary outcomes were the relationship between the tumor growth speed and mucin phenotype, tumor size and findings of magnifying endoscopy with narrow-band imaging (M-NBI).

Results: The observation period was 24 months (13-182). Tumor growth speed was 1.1 mm/year (0-21.6). Tumor diameter ≥10 mm at first detection (p = 0.004; odds ratio 19.5 [2.03-186.96]) and mixed type by M-NBI (p = 0.036; odds ratio 9.69 [1.05-89.88]) were identified as risk factors of tumors growing at a rate of ≥3 mm/year. There was no statistically significant difference in the speed of tumor growth between the different mucin immunohistochemical phenotypes.

Conclusion: Initial tumor size and findings of M-NBI are useful to predict tumor growth and consider early intervention.

Introduction: Clear guidelines for colorectal lung metastasis (LM) treatment are not available. This study aimed to provide insight into the treatment strategies and efficacy of local and systemic therapy in patients with LM eligible for (potentially) curative treatment.

Methods: This was a retrospective study of patients with ≤5 LM discussed in two tertiary referral centers. Patient and tumor characteristics were compared between treatment groups. Treatment strategies were compared between centers and survival data between treatment groups, local treatment modalities, and treating centers.

Results: Ninety-two patients (median 2 LMs) were included. Seventy-one (77%) patients underwent local treatment (17 surgery, 13 ablation, 38 radiotherapy, 3 combination of local treatments) and 21 (23%) with systemic therapy alone. The latter group more frequently had extrapulmonary metastases (81.0% vs. 26.8%, p < 0.001) and synchronous presentation of LM (23.8% vs. 7.0%, p = 0.045). Choice of local versus systemic therapy and time to start treatment after diagnosis (median 109 days, IQR 44-240 vs. 88 days, IQR 53-168) were comparable between centers. Three-year survival rates did not differ between treatment groups, local treatment modalities, or treating centers.

Conclusion: Treatment strategies and oncological outcomes were rather similar between centers. Survival outcomes were not different between locally and systemically treated patients.
