Abstract
INTRODUCTION The administration of proton pump inhibitors (PPIs) is anticipated to elevate an individual's susceptibility to enteric infections as a result of altering the gut flora. The influence of PPIs on the clinical manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still uncertain. This study aims to investigate the impact of PPI usage on the clinical manifestation of COVID-19, namely its gastrointestinal symptoms. METHODS This is a cross-sectional cohort study involving COVID-19 patients. Patients were interviewed using a predesigned questionnaire that asked about their demographics, clinical manifestations of COVID-19 infection, and the extent and type of PPIs in use. PPI usage was confirmed by reviewing patients' electronic medical records. The primary outcome was to establish any association between the use of PPI and the symptoms and clinical presentation of COVID-19. RESULTS Out of a total of 254 participants, 69 (27.2%) were considered PPI users. Patients who were on PPI medications reported a significantly lower rate of myalgia (27.5% vs 51.9%; p = 0.0006) and heartburn (5.7% vs 15.6%; p = 0.03) but had a significantly higher rate of abdominal pain (27.5% vs 13.5%; p = 0.001) and diarrhoea (28.9% vs 14.5%, p = 0.02) when compared to those who were not using PPIs. Patients on PPIs were also shown to have significantly higher odds of developing diarrhoea (OR 2.0, 95% CI: 1.08 to 3.93, p = 0.02) and abdominal pain (OR 2.0, 95% CI: 1.22 to 3.93, p = 0.03), but a lower risk of developing myalgia (OR 0.5, 95% CI: 0.3 to 0.9, p = 0.02) when compared to non-PPI users. CONCLUSION This study shows that the use of PPIs could impact COVID-19 clinical presentation toward more gastrointestinal manifestations. Further studies investigating the link between other acid suppression medications and COVID-19 manifestations and severity should be carried out.

Clarke LM, Allegretti JR. Review article: The epidemiology and management of Clostridioides difficile infection-A clinical update. Aliment Pharmacol Ther 2024; 59:1335-1349.

Abstract
BACKGROUND Clostridioides difficile is the most common cause of healthcare-associated infection, and severe cases can result in significant complications. While anti-microbial therapy is central to infection management, adjunctive therapies may be utilised as preventative strategies. AIM This article aims to review updates in the epidemiology, diagnosis, and management, including treatment and prevention, of C. difficile infections. METHODS A narrative review was performed to evaluate the current literature between 1986 and 2023. RESULTS The incidence of C. difficile infection remains significantly high in both hospital and community settings, though with an overall decline in recent years and similar surveillance estimates globally. Vancomycin and fidaxomicin remain the first line antibiotics for treatment of non-severe C. difficile infection, though due to lower recurrence rates, infectious disease society guidelines now favour use of fidaxomicin. Faecal microbiota transplantation should still be considered to prevent recurrent C. difficile infection. However, in the past year the field has had a significant advancement with the approval of the first two live biotherapeutic products-faecal microbiota spores-live brpk, an oral capsule preparation, and faecal microbiota live-jslm-both indicated for the prevention of recurrent C. difficile infection, with additional therapies on the horizon. CONCLUSION Although the prevalence of C. difficile infection remains high, there have been significant advances in the development of novel therapeutics and preventative measures following changes in recent practice guidelines, and will continue to evolve in the future.

Abstract
Background Clostridioides difficile infection (CDI) represents a significant healthcare challenge associated with antibiotic use and healthcare settings. While healthcare facility-onset CDI (HO-CDI) rates have been extensively studied, the incidence and risk factors of CDI in various settings, including the community, require further investigation. Aim This study aims to examine the incidence rates of CDI in a major governmental hospital in Bahrain, identify risk factors for CDI, and assess the effectiveness of infection control measures. Method We conducted a retrospective study at the Salmaniya Medical Complex (SMC), analyzing all confirmed cases of CDI over a 30-month period from January 2021 to June 2023. CDI cases were screened using glutamine dehydrogenase antigen detection and confirmed using molecular assays like polymerase chain reaction and/or toxin assays for confirmation. The study categorized CDI cases based on their onset (hospital or community) and explored associated risk factors, including antibiotic use, proton pump inhibitor (PPI) therapy, and patient demographics. Infection control practices were also evaluated for their role in managing CDI. Results About 57 new CDI cases were identified during the study period, with a HO-CDI incidence rate of 0.5 per 10,000 patient days. While HO-CDI rates remained stable, community-onset (CO)-CDI cases increased. The median patient age was 61.8 years, without notable differences between genders. Key risk factors for CDI were antimicrobial therapy, use of acid-reducing agents, age, and underlying comorbidities. The mortality rate stood at 35.1%. The ATLAS score (i.e., age, treatment with antibiotics, leukocyte count, albumin level, and serum creatinine) was a reliable predictor of mortality. Critical care admission and low albumin levels emerged as significant independent risk factors for mortality. Conclusions The study demonstrates a low incidence rate of HO-CDI at SMC, attributed to effective infection control and antibiotic stewardship programs. The overall CDI rate increased during the study period, driven by a rise in CO cases; further investigating the risk factors among this category in our study revealed that most patients were exposed to antibiotic therapy within the past three months of their CDI diagnosis. The rise in CO-CDI cases underscores the need for broader community-based interventions and awareness regarding antibiotic and PPI use.

Abstract
PURPOSE Patients with cancer are vulnerable to Clostridioides difficile infection (CDI) due to their disease, treatment and regular hospital contact, yet if CDI-recurrence is more common remains unclear, and differences among cancer types remain unexplored. METHODS This Swedish nationwide population-based cohort included all 43,150 individuals with recorded CDI (2006-2019) to assess CDI-recurrence in individuals with and without cancer, with binary multivariable logistic regression, stratified by anatomical location, and survival status. RESULTS Compared to those without cancer (N = 29,543), ongoing cancer (diagnosis < 12 months; N = 3,882) was associated with reduced recurrence (OR = 0.81, 95% CI 0.73-0.89), while there was no association with cancer history (diagnosis ≥ 12 months; N = 9,725). There was an increased 8-week all-cause mortality (Ongoing cancer: OR = 1.58, 95% CI 1.43-1.74; Cancer history: OR = 1.45, 95% CI 1.36-1.55) compared to those without cancer. Among CDI-survivors, those with ongoing cancer presented with a decreased odds of recurrence (OR = 0.84, 95% CI 0.76-0.94), compared to those without cancer history, with no association for those with cancer history (OR = 1.04, 95% CI 0.97-1.1). Large variations were seen across cancer types, with the highest observed proportion of recurrence in oral and mesothelial cancer, and the lowest for esophageal cancer, although no statistically significant OR were found. CONCLUSION The population-based study indicates that individuals with cancer may have fewerrecurrences than expected, yet variations by cancer type were large, and mortality was high.

Abstract
BACKGROUND Low-dose aspirin (LDA) administration is associated with an elevated risk of recurring peptic ulcer (PU) and gastrointestinal (GI) hemorrhage. AIMS This systematic review and Bayesian network meta-analysis aimed to comprehensively assess the effectiveness of diverse medications in preventing the recurrence of PU and GI hemorrhage in patients with a history of PU receiving long-term LDA therapy. METHODS This systematic review and network meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was registered on PROSPERO (CRD42023406550). We searched relevant studies in main databases from inception to March 2023. All statistical analyses were performed using R (version 4.1.3), with the "Gemtc" (version 1.0-1) package. The pooled risk ratio (RR), corresponding 95% credible interval (95% CrI), and the surface under the cumulative ranking curve (SUCRA) were calculated. RESULTS 11 Randomized clinical trials (RCTs) were included. The analysis underscored pantoprazole was the most efficacious for reducing the risk of PU recurrence (RR [95% CrI] = 0.02 [0, 0.28]; SUCRA: 90.76%), followed by vonoprazan (RR [95% CrI] = 0.03 [0, 0.19]; SUCRA: 86.47%), comparing with the placebo group. Pantoprazole also performed well in preventing GI hemorrhage (RR [95% CrI] = 0.01[0, 0.42]; SUCRA: 87.12%) compared with Teprenone. CONCLUSIONS For patients with a history of PU receiving LDA, pantoprazole and vonoprazan might be the optimal choices to prevent PU recurrence and GI hemorrhage.

Abstract
Clostridioides difficile is a well-recognized healthcare-associated pathogen, with its significance widely recognized in adult populations. Despite this, there is limited data on the significance of detection within paediatric populations, both for individual patient management and wider transmission risk-based considerations. High rates of colonization are understood to occur in infants, with increasing levels up to 11 months, and colonization rates similar to adults by 8 years old. Sources of C. difficile are ubiquitous, with detection in companion animals and food sources, as well as within the clinical and wider environment. Due to the close interactions that occur between children and the environment, it is understandable that increasing recognition is afforded to the community acquisition of C. difficile in children. Other risk factors for the detection of C. difficile in children are similar to those observed in adults, including prior hospitalization and underlying conditions affecting gut health and motility. Recent studies have shown rising awareness of the role of asymptomatic carriage of C. difficile in healthcare transmission. Prior to this, paediatric patient populations were less likely to be screened due to uncertainty regarding the significance of detection; however, this increased awareness has led to a review of possible carriage testing pathways. Despite this increased attention, C. difficile infection remains poorly defined in paediatric populations, with limited dedicated paediatric data sets making comparison challenging. This is further complicated by the fact that infection in children frequently self resolves without additional therapies. Due to this, C. difficile remains a management challenge in paediatric settings.

Abstract
OBJECTIVE Proton pump inhibitors (PPIs) are widely prescribed with proven efficacy in many indications, yet longstanding controversy about potential adverse events persists. We aimed to acquire knowledge about perceptions of outpatient PPI long-term prescribing (≥8 wk) among primary and specialty care trainees at 2 Canadian Universities. METHODS Family medicine, internal medicine, and gastroenterology trainees completed a web-based survey that included 20 clinical scenarios assessing trainee knowledge about PPI efficacy. Contextual PPI prescribing decisions were also elicited, balancing possible PPI indications versus side effects. Management strategies were compared between junior and senior trainees, as well as across training programs. RESULTS Over a 4-month period,163 trainees (age <26 y: 12%; age 26 to 45: 88%; 59% females) participated in the survey (family medicine: 51%, internal medicine: 44%, and gastroenterology: 5%); 83% were considered junior residents. Only 42% had received formal education on prescribing PPI long-term. Overall, 93% believed they would benefit from such teaching, with 98% stating they would follow related guidelines. No between-group differences were noted in knowledge of appropriate PPI indications nor possible side effects when comparing juniors to seniors, or among different specialties. Across different management scenarios, inappropriate PPI discontinuation was chosen by 14.3% to 67.2%, whereas inappropriate PPI continuation was reported in up to 57%. Trainee seniority and specialty did not differ in appropriate deprescribing rates. CONCLUSIONS Training level and primary versus specialty care settings are associated with frequent inappropriate PPI prescribing and deprescribing. These findings highlight the need for and may inform future educational programs on PPI usage.

Abstract
INTRODUCTION Limited studies have evaluated the association between Clostridium difficile infection (CDI) and the duration of proton pump inhibitor (PPI) or histamine H2-receptor blocker (H2RA) use and provided a cutoff duration for PPI or H2RA use to mitigate a substantially increased risk of CDI. We aimed to evaluate these associations in hospitalized patients using a nationwide insurance claims database. METHODS We conducted a nested case-control study to identify cases with a first ever record of CDI in a study cohort undergoing PPI or H2RA therapy from the National Health Insurance Database from 2012 to 2018. Each case was matched with one control by age, sex, and calendar year. We used conditional logistic regression to estimate the sensitivity, specificity, and area under the receiver operating characteristic curve (AUC ROC). Youden's J statistic was used to identify the optimal cutoff duration in days for PPI or H2RA use. RESULTS In the main analysis, the AUC ROC was 0.64 (95% CI 0.63-0.66) and optimal cutoff duration was 15 days for PPI users. The AUC ROC was 0.63 (95% CI 0.62-0.64) and optimal cutoff duration was 16 days for H2RA users. In the sensitivity analyses, the results were similar to those of the main analysis, and the optimal cutoff duration was in the range of 14-15 days. CONCLUSIONS The optimal cutoff duration for PPI and H2RA use was about 2 weeks. It is necessary to be cautious regarding the risk of CDI in patients taking PPIs or H2RAs for longer than 2 weeks.

Using whole genome sequencing to characterize Clostridioides difficile isolates at a tertiary center in Melbourne, Australia. ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2024; 4:e7. [PMID: 38234420 PMCID: PMC10789990 DOI: 10.1017/ash.2023.529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 11/26/2023] [Accepted: 11/28/2023] [Indexed: 01/19/2024]
Abstract
Objective Clostridioides difficile infection (CDI) is the commonest cause of healthcare-associated diarrhea and undergoes standardized surveillance and mandatory reporting in most Australian states and territories. Historically attributed to nosocomial spread, local and international whole genome sequencing (WGS) data suggest varied sources of acquisition. This study describes C. difficile genotypes isolated at a tertiary center in Melbourne, Australia, their likely source of acquisition, and common risk factors. Design Retrospective observational study. Setting The Royal Melbourne Hospital (RMH), a 570-bed tertiary center in Victoria, Australia. Methods Short-read whole genome sequencing was performed on 75 out of 137 C. difficile isolates obtained from 1/5/2021 to 28/2/2022 and compared to previous data from 8/11/2015 to 1/11/2016. Existing data from infection control surveillance and electronic medical records were used for epidemiological and risk factor analysis. Results Eighty-five (62.1%) of the 137 cases were defined as healthcare-associated from epidemiological data. On genome sequencing, 33 different multi-locus sequence type (MLST) subtypes were identified, with changes in population structure compared to the 2015-16 period. Risk factors for CDI were present in 130 (94.9%) cases, including 108 (78.8%) on antibiotics, 86 (62.8%) on acid suppression therapy, and 25 (18.2) on chemotherapy. Conclusion In both study periods, most C. difficile isolates were not closely related, suggesting varied sources of acquisition and that spread of C. difficile within the hospital was unlikely. Current infection control precautions may therefore warrant review. Underlying risk factors for CDI were common and may contribute to the proportion of healthcare-associated infections in the absence of proven hospital transmission.

Manzoor F, Manzoor S, Pinto R, Brown K, Langford BJ, Daneman N. Does this patient have Clostridioides difficile infection? A systematic review and meta-analysis. Clin Microbiol Infect 2023; 29:1367-1374. [PMID: 37327874 DOI: 10.1016/j.cmi.2023.06.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 05/27/2023] [Accepted: 06/08/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND The clinical features and predictors of Clostridioides difficile infection overlap with many conditions. OBJECTIVES We performed a systematic review to evaluate the diagnostic utility of clinical features (clinical examination, risk factors, laboratory tests, and radiographic findings) associated with C. difficile. METHODS Systematic review and meta-analysis of diagnostic features for C. difficile. DATA SOURCES MEDLINE, EMBASE, CINAHL, and Cochrane databases were searched up to September 2021. STUDY ELIGIBILITY CRITERIA Studies that reported clinical features of C. difficile, a valid reference standard test for confirming diagnosis of C. difficile, and a comparison among patients with a positive and negative test result. PARTICIPANTS Adult and paediatric patients across diverse clinical settings. OUTCOMES Sensitivity, specificity, likelihood ratios. REFERENCE STANDARD Stool nucleic acid amplification tests, enzyme immunoassays, cell cytotoxicity assay, and stool toxigenic culture. ASSESSMENT OF RISK OF BIAS Rational Clinical Examination Series and Quality Assessment of Diagnostic Accuracy Studies-2. METHODS OF DATA SYNTHESIS Univariate and bivariate analyses. RESULTS We screened 11 231 articles of which 40 were included, enabling the evaluation of 66 features for their diagnostic utility for C. difficile (10 clinical examination findings, 4 laboratory tests, 10 radiographic findings, prior exposure to 13 antibiotic types, and 29 clinical risk factors). Of the ten features identified on clinical examination, none were significantly clinically associated with increased likelihood of C. difficile infection. Some features that increased likelihood of C. difficile infection were stool leukocytes (LR+ 5.31, 95% CI 3.29-8.56) and hospital admission in the prior 3 months (LR+ 2.14, 95% CI 1.48-3.11). Several radiographic findings also strongly increased the likelihood of C. difficile infection like ascites (LR+ 2.91, 95% CI 1.89-4.49). DISCUSSION There is limited utility of bedside clinical examination alone in detecting C. difficile infection. Accurate diagnosis of C. difficile infection requires thoughtful clinical assessment for interpretation of microbiologic testing in all suspected cases.

Appropriateness of proton pump inhibitors use in noncritically ill hospitalized children in a tertiary hospital in Saudi Arabia. Saudi Pharm J 2023; 31:101723. [PMID: 37608963 PMCID: PMC10440568 DOI: 10.1016/j.jsps.2023.101723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 07/24/2023] [Indexed: 08/24/2023] Open
Abstract
Background Studies assessing the appropriate use of proton pump inhibitors (PPIs) for hospitalized noncritically ill pediatric patients are lacking. Therefore, this study aimed to assess the suitability of PPI prescriptions in noncritically ill pediatric patients. Methods This cross sectional retrospective study was conducted at a maternity hospital in Qassim, Saudi Arabia from November 2020 to January 2021. All noncritically ill hospitalized children aged 14 years and below who received PPIs were included. The endpoints included the number and percentage of patients who appropriately received PPIs in general and in each age category. The collected data were analyzed using Microsoft Excel (version 2208, Microsoft Corp., Redmond, WA, USA). Results In total, 332 medical records were screened, of which 246 were included. Of all patients, 49.2% were children and 50.8% were infants, with the average age at admission being 5.39 ± 5.4 years years. More than half of the patients were female, and the average weight of patients was 19.8 kg. Omeprazole was appropriately used in 95 (38.5%) patients. Based on age groups, omeprazole was appropriately used in 66.3% of children and 38.4% of infants. Conclusion The use of omeprazole in noncritically ill pediatrics was only deemed appropriate in 38.6% of the study population. This result indicates that this medication was overused in the institution. Additional research is required to confirm this on a nationwide scale.

The Environment, Farm Animals and Foods as Sources of Clostridioides difficile Infection in Humans. Foods 2023; 12:foods12051094. [PMID: 36900611 PMCID: PMC10000743 DOI: 10.3390/foods12051094] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 02/21/2023] [Accepted: 02/28/2023] [Indexed: 03/08/2023] Open
Abstract
The recent discovery of the same Clostridioides difficile ribotypes associated with human infection in a broad range of environments, animals and foods, coupled with an ever-increasing rate of community-acquired infections, suggests this pathogen may be foodborne. The objective of this review was to examine the evidence supporting this hypothesis. A review of the literature found that forty-three different ribotypes, including six hypervirulent strains, have been detected in meat and vegetable food products, all of which carry the genes encoding pathogenesis. Of these, nine ribotypes (002, 003, 012, 014, 027, 029, 070, 078 and 126) have been isolated from patients with confirmed community-associated C. difficile infection (CDI). A meta-analysis of this data suggested there is a higher risk of exposure to all ribotypes when consuming shellfish or pork, with the latter being the main foodborne route for ribotypes 027 and 078, the hypervirulent strains that cause most human illnesses. Managing the risk of foodborne CDI is difficult as there are multiple routes of transmission from the farming and processing environment to humans. Moreover, the endospores are resistant to most physical and chemical treatments. The most effective current strategy is, therefore, to limit the use of broad-spectrum antibiotics while advising potentially vulnerable patients to avoid high-risk foods such as shellfish and pork.

Abstract
BACKGROUND Vonoprazan, a potassium-competitive acid blocker (VPZ), significantly reduces postoperative bleeding after gastric ESD; however, there is no consensus on the appropriate treatment duration. We conducted a randomized controlled study to demonstrate that the 3-week administration of VPZ is not inferior to the 8-week administration for ulcer healing. METHODS This is a prospective, open-label multicenter randomized controlled trial. Patients aged 20-85 years undergoing gastric ESD were included in this study. The key exclusion criteria were patients with bleeding tendencies and those taking NSAIDs, steroids, PPIs, or VPZ medications. Eligible patients were randomly assigned to the VPZ 3w or 8w treatment group. The primary endpoint was the proportion of patients with complete closure of the post-ESD wound at 24 weeks after ESD. The key secondary endpoints included the proportion of patients with complete closure of the post-ESD wound at 8 weeks and the proportion of bleeding or perforation more than 3 weeks after ESD. RESULTS From May 2018 to October 2020, 234 patients were included. The proportion of patients with complete ulcer closure was significantly lower in the 3w group than in the 8w group (70.8% vs. 90.6%) at 8 weeks post-treatment. The complete closure rates at 24 weeks in the 3w and 8w groups were 99.1% and 99.2%, respectively. The absolute difference in the closure rate at 24 weeks was - 0.059% [95% confidence interval (CI) -3.4% to 3.2], and the lower limit of the 95% CI exceeded -10%, the preset threshold. None of the patients developed delayed bleeding 3 weeks after ESD. CONCLUSION This multicenter randomized study demonstrated that 3 weeks of treatment with VPZ is sufficient for ulcer healing.

Abstract
Overuse of antacids is associated with the development and recurrence of Clostridioides difficile infection (CDI). Discontinuation of unnecessary antacids for CDI management is advocated; however, the clinical pervasiveness on the discontinuation of antacids remains unclear. We conducted a single-center retrospective observational study to determine the rate of antacid discontinuation following CDI diagnosis. Among 51 patients (58 infections; median age 76.5 years, range 69-82; 53.5% women) treated with antimicrobials against C. difficile, 41 had been treated with antacids, and of these, 18 exhibited no indication for antacid administration. However, none had discontinued antacid use. While CDI provides an opportunity for antacid stewardship, it is not implemented in clinical practice. In addition to the efforts of individual clinicians, the dissemination of knowledge of the indications and side effects of antacids, establishment of a multidisciplinary support system, and creation and implementation of a clinical stewardship pathway are necessary to increase the deprescription of antacids in patients with CDI.

Abstract
Background Advanced age and underlying comorbidities are associated with greater rates of recurrence in patients with Clostridioides difficile infection (CDI). Reducing the likelihood of recurrence through treatment with an antimicrobial followed by a microbiota replacement therapy can decrease the burden of this infection and improve patient outcomes. We report the efficacy and safety of RBX2660, a microbiota-based live biotherapeutic, in older adults with recurrent CDI, grouped by comorbidities. Methods In this post hoc subgroup analysis of the PUNCH CD3 trial, we assessed outcomes in older adults (age ≥65 years) grouped by Charlson Comorbidity Index severity scores at screening (moderate [3-4] and severe [≥5]) and by the presence of underlying cardiac, renal, or gastrointestinal disorders. Results RBX2660 treatment success rates in older adults with comorbidities were consistent across subgroups and similar to those in the total RBX2660-treated population. A greater percentage of RBX2660-treated older adults remained free of CDI recurrence through 8 weeks following treatment compared with placebo-treated participants in all but 2 subgroups assessed. Across all subgroups, most treatment-emergent adverse events (TEAEs) were mild or moderate in severity and related to a preexisting condition. None of the serious or life-threatening TEAEs that occurred were related to RBX2660 or its administration. Occurrence of TEAEs did not cluster in any subgroup. Conclusions RBX2660 is efficacious and safe in older adults with recurrent CDI and underlying comorbidities.

Abstract
Proton pump inhibitors (PPIs) have several limitations to their efficacy including insufficient acid suppression, slow onset of action, and variable efficacy among patients due to CYP2C19 metabolism. Potassium-competitive acid blockers inhibit H+-K+-ATPase in a reversible and K+-competitive manner, are novel acid suppressive drugs with rapid onset of action, meal independence, and prolonged control of intragastric acidity compared to PPIs. Potassium-competitive acid blockers exhibited non-inferior therapeutic efficacies on reflux esophagitis, gastric ulcers, and Helicobacter pylori eradication. The review is focused on the unmet needs across the acid-related diseases and recent updates on clinical studies using vonoprazan and tegoprazan.

Abstract
Clostridioides difficile infection (CDI) is associated with high mortality rates among patients with chronic illnesses. We aimed to identify avoidable risk factors to reduce the mortality rate in CDI patients. A total of 306 patients with diarrhea and clinical suspicion of CDI were enrolled, and fecal samples were gathered from 145 patients. CDI was diagnosed by fecal positivity for the C. difficile tcdB gene. Risk factors associated with death within 180 days were identified using Cox regression analysis. The fecal microbiota was determined through bacterial 16S rRNA gene sequencing. Of the patients with diarrhea, 240 (mean age, 69.1 years) were positive for CDI, and 91 died within 180 days. Multivariate analysis revealed that male sex, high Charlson Comorbidity Index and McCabe scores, high serum C-reactive protein levels, low hematocrit levels, low absolute eosinophil counts, high neutrophil/lymphocyte ratios, and daily use of proton pump inhibitors (PPIs) were independent risk factors for overall mortality. Cumulative analyses confirmed the association of duration-dependent PPI use with a high mortality rate. Fecal microbiota analyses showed associations of decreased relative abundance of Ruminococcus gnavus (P = 0.001) and Prevotella copri (P = 0.025) and increased relative abundance of Parabacteroides merdae (P = 0.001) and Clostridioides difficile (P = 0.040) with higher mortality rates in patients with CDI. Moreover, these microbiota changes were correlated with the duration of PPI use. IMPORTANCE This article demonstrates that daily PPI use was the only avoidable risk factor for death. With more extended PPI use, the mortality rate was higher in patients with CDI. Decreases in Prevotella copri and Ruminococcus gnavus and increases in Parabacteroides merdae and Clostridioides difficile in line with daily PPI use duration were significantly associated with the death of CDI patients. Our findings provide in-depth insights into the cautious use of PPIs in chronically ill patients with CDI.

Abstract
Clostridium difficile infection (CDI) is the most common nosocomial infection in hospitals. Despite the fact that CDI has treatment options, recurrence is common after the treatment, recurrence will occur in approximately 20%-35% of people initially affected, with 40%-60% of these having a second recurrence. Patients are more likely to have several recurrences after the second, which can lead to antibiotic overuse, and as a result, CDI-related health care expenses, hospitalizations, and mortality are on the rise. The first treatment to receive Food and Drug Administration (FDA) approval for the prevention of C. difficile recurrence is bezlotoxumab, a novel human monoclonal antibody against C. difficile toxin B. In the present systematic review, we assessed various studies from PubMed, PubMed Central (PMC), Google Scholar, and Science direct that evaluated the efficacy of bezlotoxumab in the prevention of recurrent C. difficile (rCDI), and we also briefly discussed the pathophysiology of C. difficile and the risk factors for recurrence of C. difficile. The major MODIFY trial has proven the efficacy, pooled analysis of MODIFY 1 AND 2 trials demonstrated the following results as compared to placebo (bezlotoxumab: 129/781 [16.5] placebo:206/773 [26.6] -10.0% [95% CI -14.0 to -6.0], p<0.0001) with number needed to treat (NNT) of 10. All other observational studies also showed a positive response with bezlotoxumab in the prevention of C. difficile. In conclusion, bezlotoxumab is a great option adjunctive with standard of care CDI antibiotics for the prevention of rCDI in high-risk adults.

Abstract
Objective To determine whether the long-term care facility (LTCF) Centers for Medicare & Medicaid Services (CMS) Antimicrobial Stewardship (AMS) mandate was associated with a change in the combined rate of LTCF-acquired multidrug-resistant organism infection or colonization (MDRO-I/C) and Clostridioides difficile infection (CDI). Design Retrospective quasi-experimental study. Setting A 233-bed community hospital. Participants LTCF residents 75 years of age and older with MDRO-I/C or CDI admitted to the hospital before the AMS mandate in 2015 through 2016 or after the mandate in 2018 through 2019. Intervention LTCF CMS AMS mandate. Main Outcomes Measures Rates of LTCF-acquired MDRO-I/C and CDI. MDRO-I/C were defined by a culture positive for methicillin-resistant Staphylococcus aureus or extended-spectrum beta-lactamase-producing Enterobacterales. CDI was defined by a positive test for C. difficile using a multistep algorithm of toxin, glutamate dehydrogenase, and nucleic acid amplification tests. These specimens must have been collected within 48 hours of hospital admission. Results There were 33 residents with either LTCF-acquired MDRO-I/C or CDI out of a total of 205 hospitalized residents with MDRO-I/C or CDI in 2015 and 2016, resulting in a rate of 16.10%. In comparison, there were 38 residents with either LTCF-acquired MDRO-I/C or CDI out of a total of 253 hospitalized residents with MDRO-I/C or CDI in 2018 and 2019 resulting in a rate of 15.02%. The difference in the combined rate of LTCF-acquired MDRO-I/C and CDI was -1.08% (P = 0.75). Conclusion The AMS mandate was not associated with a significant change in the combined rate of LTCF-acquired MDRO-I/C and CDI, suggesting a need for more robust AMS programs in LTCFs.

Abstract
Clostridioides difficile infection (CDI) is one of the most common causes of antibiotic-associated diarrhea. The pathogenesis of this infection participates in the unstable colonization of the intestines with the physiological microbiota. Solid-organ-transplant (SOT) patients and patients after hematopoietic stem cell transplantation are more prone to CDI compared to the general population. The main CDI risk factors in these patients are immunosuppressive therapy and frequent antibiotic use leading to dysbiosis. The current review article provides information about the risk factors, incidence and course of CDI in patients after liver, kidney, heart and lung transplantation and hematopoietic stem cell transplantation.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are one of the most prescribed drugs in the world. Frequent use and long-term maintenance of these drugs drew the attention of researchers for sporadic adverse effects reports. OBJECTIVE The purpose of this narrative review is to discuss appropriate data and causality related to these adverse events and PPIs. METHODS A narrative review was conducted by systematizing information about safety and adverse events on PPIs from 2015 to 2020. A structured search on Pubmed was performed to identify systematic reviews and meta-analysis investigating the following situations: a) gastric cancer; b) micronutrients deficiency; c) acid rebound; d) infections; e) fractures; f) dementia; g) kidney disease; and h) sudden death and cardiovascular changes. RESULTS Recent studies have potentially associated PPIs with some adverse events as osteoporosis-related fractures. There are also reports of intestinal infections, including Clostridium difficile, besides poor vitamins absorption and minerals such as vitamin B12, magnesium, and iron. Furthermore, there are some dementia, pneumonia, kidney disease, myocardial infarction, and stroke reports. For kidney diseases, studies consistently suggest that the use of PPI may be associated with an increased risk of adverse kidney events, especially in the elderly, with long-term PPI use and pre-existing kidney disease. Another additional question is whether chronic PPI use would also lead to the onset of gastric cancer. The abrupt discontinuation of PPIs is also related to increased gastric acid production above pre-PPI treatment levels; this phenomenon is called acid rebound. CONCLUSION The key to mitigate adverse effects is the rational use of PPIs at the lowest effective dose and in the shortest possible duration. Although these adverse effects have a potential clinical impact, their causal association is still subject to validation.

Abstract
Gastroesophageal reflux disease (GERD) continues to be among the most common diseases seen by gastroenterologists, surgeons, and primary care physicians. Our understanding of the varied presentations of GERD, enhancements in diagnostic testing, and approach to patient management have evolved. During this time, scrutiny of proton pump inhibitors (PPIs) has increased considerably. Although PPIs remain the medical treatment of choice for GERD, multiple publications have raised questions about adverse events, raising doubts about the safety of long-term use and increasing concern about overprescribing of PPIs. New data regarding the potential for surgical and endoscopic interventions have emerged. In this new document, we provide updated, evidence-based recommendations and practical guidance for the evaluation and management of GERD, including pharmacologic, lifestyle, surgical, and endoscopic management. The Grading of Recommendations, Assessment, Development, and Evaluation system was used to evaluate the evidence and the strength of recommendations. Key concepts and suggestions that as of this writing do not have sufficient evidence to grade are also provided.

Abstract
The human stomach functions as both a digestive and innate immune organ. Its main product, acid, rapidly breaks down ingested products and equally serves as a highly effective microbial filter. The gastric epithelium has evolved mechanisms to appropriately handle the myriad of injurious substances, both exogenous and endogenous, to maintain the epithelial barrier and restore homeostasis. The most significant chronic insult that the stomach must face is Helicobacter pylori (Hp), a stomach-adapted bacterium that can colonize the stomach and induce chronic inflammatory and pre-neoplastic changes. The progression from chronic inflammation to dysplasia relies on the decades-long interplay between this oncobacterium and its gastric host. This review summarizes the functional and molecular regionalization of the stomach at homeostasis and details how chronic inflammation can lead to characteristic alterations in these developmental demarcations, both at the topographic and glandular levels. More importantly, this review illustrates our current understanding of the epithelial mechanisms that underlie the pre-malignant gastric landscape, how Hp adapts to and exploits these changes, and the clinical implications of identifying these changes in order to stratify patients at risk of developing gastric cancer, a leading cause of cancer-related deaths worldwide.

Abstract
SCOPE In 2009, the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) published the first treatment guidance document for Clostridioides difficile infection (CDI). This document was updated in 2014. The growing literature on CDI antimicrobial treatment and novel treatment approaches, such as faecal microbiota transplantation (FMT) and toxin-binding monoclonal antibodies, prompted the ESCMID study group on C. difficile (ESGCD) to update the 2014 treatment guidance document for CDI in adults. METHODS AND QUESTIONS Key questions on CDI treatment were formulated by the guideline committee and included: What is the best treatment for initial, severe, severe-complicated, refractory, recurrent and multiple recurrent CDI? What is the best treatment when no oral therapy is possible? Can prognostic factors identify patients at risk for severe and recurrent CDI and is there a place for CDI prophylaxis? Outcome measures for treatment strategy were: clinical cure, recurrence and sustained cure. For studies on surgical interventions and severe-complicated CDI the outcome was mortality. Appraisal of available literature and drafting of recommendations was performed by the guideline drafting group. The total body of evidence for the recommendations on CDI treatment consists of the literature described in the previous guidelines, supplemented with a systematic literature search on randomized clinical trials and observational studies from 2012 and onwards. The Grades of Recommendation Assessment, Development and Evaluation (GRADE) system was used to grade the strength of our recommendations and the quality of the evidence. The guideline committee was invited to comment on the recommendations. The guideline draft was sent to external experts and a patients' representative for review. Full ESCMID endorsement was obtained after a public consultation procedure. RECOMMENDATIONS Important changes compared with previous guideline include but are not limited to: metronidazole is no longer recommended for treatment of CDI when fidaxomicin or vancomycin are available, fidaxomicin is the preferred agent for treatment of initial CDI and the first recurrence of CDI when available and feasible, FMT or bezlotoxumab in addition to standard of care antibiotics (SoC) are preferred for treatment of a second or further recurrence of CDI, bezlotoxumab in addition to SoC is recommended for the first recurrence of CDI when fidaxomicin was used to manage the initial CDI episode, and bezlotoxumab is considered as an ancillary treatment to vancomycin for a CDI episode with high risk of recurrence when fidaxomicin is not available. Contrary to the previous guideline, in the current guideline emphasis is placed on risk for recurrence as a factor that determines treatment strategy for the individual patient, rather than the disease severity.

Acid Suppression Does Not Improve Laryngomalacia Outcomes but Treatment for Oropharyngeal Dysphagia Might Be Protective. J Pediatr 2021; 238:42-49.e2.

Abstract
OBJECTIVE To determine whether the use of acid suppression and thickened feeds impact laryngomalacia outcomes in infants, including supraglottoplasty risk, time to supraglottoplasty, and hospitalization risk. STUDY DESIGN We performed a retrospective cohort study to compare risk and time with supraglottoplasty and frequency and duration of hospitalizations for infants diagnosed with laryngomalacia at Boston Children's Hospital between January 1 and December 31, 2017. The primary outcomes were supraglottoplasty requirement, time to supraglottoplasty, and hospitalization risk. Multivariate analyses were performed to determine predictors of supraglottoplasty and hospitalization risk after adjusting for laryngomalacia severity and comorbidities in addition to propensity score adjustment. Kaplan-Meier curves were created to determine the impact of acid suppression use on time to supraglottoplasty. RESULTS In total, 236 subjects with mean age 62.6 ± 4 days were included in the analysis; 55% were treated with acid suppression. Subjects treated with acid suppression had a greater risk of supraglottoplasty (hazard ratio 3.36, 95% CI 1.36-8.29, P = .009), shorter time to supraglottoplasty (5.64 ± 0.92 vs 7.98 ± 1.92 months, P = .006), and increased respiratory hospitalization risk (relative risk 1.97, 95% CI 1.01-3.85, 0.047), even after adjustment for covariates. Subjects receiving thickening had fewer respiratory hospitalization nights and longer time to supraglottoplasty (9.3 ± 1.7 vs 4.56 ± 0.73 months, P = .004), even after adjustment. CONCLUSIONS Acid suppression use does not reduce the frequency of supraglottoplasty and related hospitalizations compared with untreated subjects. However, patients treated with thickening have decreased hospitalization and longer time to supraglottoplasty, suggesting that thickening of feeds may be a preferred intervention over acid suppression.

Abstract
Gastroesophageal reflux disease (GERD) is a condition in which gastric contents regurgitate into the esophagus or beyond, resulting in either troublesome symptoms or complications. GERD is heterogeneous in terms of varied manifestations, test findings, and treatment responsiveness. GERD diagnosis can be established with symptomatology, pathology, or physiology. Recently the Lyon consensus defined the “proven GERD” with concrete evidence for reflux, including advanced grade erosive esophagitis (Los Angeles classification grades C and or D esophagitis), long-segment Barrett’s mucosa or peptic strictures on endoscopy or distal esophageal acid exposure time > 6% on 24-hour ambulatory pH-impedance monitoring. However, some Asian researchers have different opinions on whether the same standards should be applied to the Asian population. The prevalence of GERD is increasing in Asia. The present evidence-based guidelines were developed using a systematic review and meta-analysis approach. In GERD with typical symptoms, a proton pump inhibitor test can be recommended as a sensitive, cost-effective, and practical test for GERD diagnosis. Based on a meta-analysis of 19 estimated acid-exposure time values in Asians, the reference range upper limit for esophageal acid exposure time was 3.2% (95% confidence interval, 2.7-3.9%) in the Asian countries. Esophageal manometry and novel impedance measurements, including mucosal impedance and a post-reflux swallow-induced peristaltic wave, are promising in discrimination of GERD among different reflux phenotypes, thus increasing its diagnostic yield. We also propose a long-term strategy of evidence-based GERD treatment with proton pump inhibitors and other drugs.

Abstract
BACKGROUND AND STUDY AIMS Proton pump inhibitors (PPI) are one of the most often prescribed drugs worldwide. They were thought to have a great safety profile before adverse effects in case of long-term medication were discussed recently. Undoubtedly, the use of PPI has to be based on a clear indication. In this retrospective analysis, we investigated the number of patients being discharged from a gastroenterological department with a PPI medication. We also analyzed if this recommendation was based on an established indication and if dose and duration of therapy were correct. PATIENTS AND METHODS 1612 discharge letters from the period January 1st to June 30th 2011 were evaluated. Patients being discharged with a recommendation of PPI use were assigned to one of four groups: (1) PPI recommendation correct according to guidelines indication, dose and duration of treatment; (2) PPI recommendation correct according to guidelines indication, but with failing or false dose or duration of treatment; (3) PPI recommendation rational but not based on guidelines; (4) Failing indication, wrong recommendation. For a more detailed analysis the patients of group 1 to 4 were then assigned to various subgroups according to comorbidities and concomitant medication. RESULTS 808 of 1612 discharge letters (50,1%) recommended a PPI use. Assignment to the four groups were as follows: (1) n=344 (42,6%); (2) n=115 (14,2%); (3) n=159 (19,7%); (4) n=190 (23,5%). CONCLUSIONS At time of discharge, PPI are frequently and partially uncritically recommended. Therefore, there is a need for a more intensive education of training interns and for a more critical review of the discharge letters by senior physicians. Even in case of optimal realization of these needs about 20% of debatable recommendations are not based on current guidelines.

Abstract
INTRODUCTION Clostridioides difficile (C. difficile) infection (CDI) is the most common cause of antibiotic-associated diarrhea and one of the common infections in healthcare facilities. In recent decades, there has been an emerging threat of community-acquired CDI (CA-CDI). Environmental transmission of C. difficile in the community setting has become a major concern, and animals are an important reservoir for C. difficile causing human diseases. AREAS COVERED In this article, the molecular epidemiology of C. difficile in animals and recent evidences of zoonotic transfer to humans are reviewed based on an electronic search in the databases of PubMed and Google Scholar. EXPERT OPINION C. difficile can be found in stool from diarrheal dogs and cats; therefore, household pets could be a potential source. C. difficile will threaten human health because hypervirulent C. difficile ribotype 078 strains have been found in retail chickens, pig farms, and slaughterhouses. Risk factors for fecal C. difficile carriage in animals include young age, dietary changes, and antibiotic abuse in domestic animals. With the advent of whole genome sequencing techniques, there will be more solid evidence indicating zoonotic transfer of C. difficile from animals to humans.

Abstract
Protein-based targeting reagents, such as antibodies and non-antibody scaffold proteins, are rapidly inactivated in the upper gastrointestinal (GI) tract. Hydrochloric acid in gastric juice denatures proteins and activates pepsin, concentrations of which reach 1 mg/mL in the mammalian stomach. Two stable scaffold proteins (nanobody and nanofitin), previously developed to be protease-resistant, were completely digested in less than 10 min at 100-fold lower concentration of pepsin than found in the stomach. Here we present gastrobodies, a protein scaffold derived from Kunitz soybean trypsin inhibitor (SBTI). SBTI is highly resistant to the challenges of the upper GI tract, including digestive proteases, pH 2 and bile acids. Computational prediction of SBTI's evolvability identified two nearby loops for randomization, to create a potential recognition surface which was experimentally validated by alanine scanning. We established display of SBTI on full-length pIII of M13 phage. Phage selection of gastrobody libraries against the glucosyltransferase domain of Clostridium difficile toxin B (GTD) identified hits with nanomolar affinity and enzyme inhibitory activity. Anti-GTD binders retained high stability to acid, digestive proteases and heat. Gastrobodies show resilience to exceptionally harsh conditions, which should provide a foundation for targeting and modulating function within the GI tract.

Abstract
OBJECTIVE To assess the impact of prophylactic omeprazole and famotidine on the incidence and severity of gastrointestinal (GI) adverse events (AEs) in dogs with cancer treated with single agent piroxicam. ANIMALS 39 dogs with a cytologic or histologic diagnosis of cancer with no history of GI disease and received piroxicam. PROCEDURES A prospective, randomized, placebo-controlled, double-blinded clinical trial was performed. All dogs received piroxicam (0.3 mg/kg [0.14 mg/lb], PO, q 24 h) and either omeprazole (1 mg/kg [0.45 mg/lb], PO, q 12 h), famotidine (1 mg/kg, PO, q 12 h), or placebo (lactose; PO, q 12 h). Monthly assessments of GI AEs were performed and scored by using the Veterinary Comparative Oncology Group's Common Terminology Criteria for Adverse Events (version 1.1). RESULTS Compared with dogs in the placebo group, more dogs in the omeprazole group (84.6% vs 36.4%) and famotidine group (80.0% vs 36.4%) experienced GI AEs by day 56. The severity of GI AEs was higher in the omeprazole group, compared with the placebo group. CONCLUSIONS AND CLINICAL RELEVANCE Omeprazole was not helpful in reducing the frequency or severity of GI AEs and was associated with more frequent and severer GI AEs in dogs with cancer treated with single agent piroxicam. Proton-pump inhibitors and H2-receptor antagonists should not be prescribed as prophylaxis with NSAIDs for dogs with cancer.

Abstract
Clostridioides difficile infection (CDI) is an urgent health threat being the most common healthcare-associated infection, and its management is a clinical conundrum. Over 450 000 infections are seen in the United States with similar incidence seen in the rest of the developed world. The majority of infections seen are mild-moderate with fulminant disease and mortality being rare complications seen in the elderly and in those with comorbidities. The most common complication of CDI is recurrent infection with rates as high as 60% after three or more infections. A dilemma in the management of primary and recurrent CDI is testing due to the high sensitivity of the nucleic acid amplification tests such as the polymerase chain reaction, which leads to clinical false positives if patients are not chosen carefully (with symptoms) before testing. A newer testing regimen involving a 2-step strategy is emerging using glutamate dehydrogenase as a screening strategy followed by enzyme immunoassay for the C. difficile toxin. Microbiota restoration therapies are the cornerstone of management of recurrent CDI to prevent future recurrences. The most common modality of microbiota restoration is faecal microbiota transplantation, which has been tainted with heterogeneity and adverse events such as serious infectious transmission. The success rates for recurrence prevention from microbiota restoration therapies are over 90% compared with less than 50% of recurrence prevention with courses of antibiotics. This has led to development and emergence of standardized microbiota restoration therapies in capsule and enema forms. Capsule-based therapies include CP101 (positive phase II results), RBX7455 (positive phase I results), SER-109 (positive phase III results) and VE303 (ongoing phase II trial). Enema-based therapy includes RBX2660 (positive phase III data). This review summarizes the principles of management and diagnosis of CDI and focuses on emerging and existing data on faecal microbiota transplantation and standardized microbiota restoration therapies.

Abstract
BACKGROUND Studies have had conflicting results regarding the influence of acid-suppression medications (ASMs) during hospitalization on the recurrence of Clostridioides difficile infection (CDI). METHODS A systematic review and meta-analysis investigating the association between recurrent CDI and ASM use in inpatients was performed. Relevant literature was identified using Medline, Google Scholar, and Web of Science. All human studies were considered regardless of publication date. Case-control and cohort studies and clinical trials were included if they contained the necessary information to calculate appropriate statistics related to the objective of this study. Review articles, meta-analyses, and commentaries were excluded; however, their references were searched to identify any studies missed. The random-effects model was selected since significant heterogeneity in study design was identified. To evaluate the sensitivity of the analysis various subgroup analyses were performed. RESULTS Our search identified 9 studies involving 5668 patients of whom 1003 (17.7%) developed recurrent CDI. Patients on ASM were 64% more likely to develop recurrent CDI than patients not on ASM (OR, 1.64; 95% CI, 1.13-2.38; P = .009; I2 = 79.54%). Proton pump inhibitor (PPI) use was associated with an 84% increased risk of recurrent CDI versus no ASM (OR, 1.84; 95% CI, 1.18-2.85; P = .007; I2 = 83.4%). CONCLUSIONS ASM use during hospitalization was associated with a 64% increase in recurrent CDI. The association was greater with PPI use. Due to significant heterogeneity in the analyses, additional studies are essential to further elucidate iatrogenic effects of ASM. Unnecessary PPI use should be discontinued.

Abstract
BACKGROUND AND GOALS Clostridioides difficile infection (CDI) recurs in 10% to 15% after fecal microbiota transplantation (FMT). We identify predictors, and describe management and outcome of patients with recurrent CDI after FMT in a predominantly outpatient cohort. METHODS A nested case-control study of patients undergoing FMT for recurrent CDI from August 2012 to January 2017 was performed. FMT failure was defined as recurrent diarrhea with positive C. difficile stool test during follow-up (≥2 mo). Controls (patients without FMT failures) were matched to cases 1:1 for sex and timing of FMT±1 month. RESULTS Overall, 522 patients underwent FMT; 70 [13.4%; median age 53.8 years (range, 18 to 89 y), 54.3% females] recurred within a median 5.6 months (range, 0.2 to 34.9 mo). Number of prior CDI episodes, prior CDI treatment, and prior CDI-related hospitalizations were similar in cases and controls. Systemic antibiotics after FMT (54.3% vs. 21.4%, P<0.0001), inflammatory bowel disease (IBD) (34.3% vs. 15.7%, P=0.01), pseudomembranes at FMT (4.3% vs. 0%, P=0.03), and poor bowel preparation (68.5% vs. 31.4%, P=0.01) were associated with FMT failure. On multivariate analysis, IBD [odds ratio (OR) 4.34; 95% confidence interval (CI), 1.24-15.15], systemic antibiotics (OR 7.39; 95% CI, 3.02-18.07), and poor bowel preparation (OR 3.84; 95% CI, 1.59-9.28) predicted FMT failure with an area under the curve of 0.78. Among FMT failures, 37 (52.8%) were managed with antibiotics, 32 (45.7%) with repeat FMT after antibiotics and 1 with colectomy. CONCLUSIONS Use of systemic antibiotics, IBD, and poor bowel preparation predict FMT failure. Patients with FMT failure can be managed with antibiotics and/or repeat FMT.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recently emerged as a highly virulent respiratory pathogen that is known as the causative agent of coronavirus disease 2019 (COVID-19). Diarrhea is a common early symptom in a significant proportion of patients with SARS-CoV-2 infection. SARS-CoV-2 can infect and replicate in esophageal cells and enterocytes, leading to direct damage to the intestinal epithelium. The infection decreases the level of angiotensin-converting enzyme 2 receptors, thereby altering the composition of the gut microbiota. SARS-CoV-2 elicits a cytokine storm, which contributes to gastrointestinal inflammation. The direct cytopathic effects of SARS-CoV-2, gut dysbiosis, and aberrant immune response result in increased intestinal permeability, which may exacerbate existing symptoms and worsen the prognosis. By exploring the elements of pathogenesis, several therapeutic options have emerged for the treatment of COVID-19 patients, such as biologics and biotherapeutic agents. However, the presence of SARS-CoV-2 in the feces may facilitate the spread of COVID-19 through fecal-oral transmission and contaminate the environment. Thus gastrointestinal SARS-CoV-2 infection has important epidemiological significance. The development of new therapeutic and preventive options is necessary to treat and restrict the spread of this severe and widespread infection more effectively. Therefore, we summarize the key elements involved in the pathogenesis and the epidemiology of COVID-19-associated diarrhea.

Abstract
Clostridioides difficile infection occurs when the bacterium produces toxin that causes diarrhea and inflammation of the colon. These guidelines indicate the preferred approach to the management of adults with C. difficile infection and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation process. In instances where the evidence was not appropriate for Grading of Recommendations Assessment, Development, and Evaluation but there was consensus of significant clinical merit, key concept statements were developed using expert consensus. These guidelines are meant to be broadly applicable and should be viewed as the preferred, but not the only, approach to clinical scenarios.

Abstract
OBJECTIVE To evaluate deprescribing of select high-risk medications (HRMs) in an Acute Care for the Elderly (ACE) unit with pharmacist involvement compared with usual care in older people. DESIGN Retrospective, single-center case-control study. SETTING Medical-surgical units at an urban academic medical center. PARTICIPANTS Patients 65 years of age and older admitted April-June 2019, with 1 or more of the following target HRMs prior to admission were included in the study: acid suppressants, antipsychotics, or insulin. Patients admitted to the ACE unit were included in the case group; all other patients were randomly matched by HRMs in a 2:1 ratio into the control group. INTERVENTIONS The Acute Care for the Elderly pharmacist reviewed patients' medications to identify and deprescribe select HRMs. Deprescribing was defined as discontinuation, dose or frequency reduction. RESULTS A total of 47 patients with 56 HRMs and 89 patients with 126 HRMs were included in the case and control groups, respectively. The primary outcome of HRMs deprescribed were similar between the case and control groups (21.4% and 25.4%; P = 0.56). Among the HRMs deprescribed (discontinued, dose or frequency reduced), 83.2% were complete discontinuations in case patients and 34.4% were complete discontinuations in control patients.

Abstract
OBJECTIVES The purpose of this study was to identify risk factors for initial complicated Clostridioides difficile infection (CDI). METHODS This retrospective cross-sectional study included adult patients with initial episodes of CDI who received ≥72 h of CDI-active antimicrobials. Patients were categorised into one of two groups: complicated CDI or uncomplicated CDI. A total of 513 patients were screened for inclusion, with complicated CDI patients exhibiting abnormal abdominal CT findings or experiencing death within 30 days post-CDI diagnosis. RESULTS A total of 203 patients met the inclusion criteria, comprising 143 (70.4%) with uncomplicated CDI and 60 (29.6%) with complicated CDI. Complicated CDI patients were more likely to have been exposed to fluoroquinolones (48.3% vs. 30.8%; P = 0.017) and to carbapenems for a longer duration prior to CDI diagnosis (7 days vs. 3 days; P = 0.019). They were more likely to receive oral vancomycin (65.0% vs. 46.9%; P = 0.018) and rectal vancomycin (5.0% vs. 0%; P = 0.025) compared with uncomplicated CDI patients. Logistic regression identified previous fluoroquinolone exposure increased the risk of complicated CDI, while previous abdominal surgery decreased the risk. CONCLUSION Almost one-third of included patients experienced a complicated episode of CDI as their initial episode. Further research is warranted to elucidate the extent of influence of prior antibiotics on the development of complicated CDI.

Abstract
Der gastroösophageale Reflux, auch GERD genannt (gastroesophageal reflux disease) ist mit einer Prävalenz von 20-30% der erwachsenen Bevölkerung ein weit verbreitetes Problem. Davon abzugrenzen ist der häufig in der HNO-Praxis anzutref-fende laryngopharyngeale Reflux (LPR), bei dem es sich um eine durch den Magensäurereflux bedingte Entzündung der oberen Atemwege handelt. Die Unterschiede im klinischen Bild charakterisieren die widersprüchliche Beziehung der beiden klinischen Entitäten und erschweren die Diagnosestellung. Darüber hinaus muss ein besonderes Augenmerk auf Beschwerden des Magen- und Darmtrakts gelegt und deren Behandlung nicht vernachlässigt werden. Neben diätetischen Ratschlägen zählen einige pflanzliche Arzneimittel zu den Therapieoptionen. Alginate, die ein Aufstossen verhindern, bewähren sich in der Praxis. Kombinationsarzneimittel aus der europäischen und tibetischen Tradition spielen eine wesentliche Rolle in der Behandlung, nicht nur des LPR sondern auch bei Verdauungsproblemen des oberen und unteren Verdauungstrakts, wie Reizmagen und Reizdarm. The gastroesophageal reflux, also called GERD (gastroesophageal reflux disease), is a widespread problem with 20–30% of the adult population concerned. The laryngopharyngeal reflux (LPR), which is an inflammation of the upper respiratory system due to reflux of gastric acids, is a frequently encountered problem of the gastrointestinal practitioner and should be separated from GERD. The differences in the clinical image characterize the contradictory relationship of both clinical entities and complicate the diagnosis. In addition, the focus should also be turned on eventual disorders of the gastrointestinal tract and, if necessary, they should be treated, too. Besides dietetic advice some herbal medicines belong to the therapeutic options. Alginates, which prevent reflux, have proved a great value in the practice. Multicomponent mixtures originating from the European and Tibetan herbal medicine traditions play a major role in the treatment, not only for LPR, but also for the upper and lower digestive pathologies such as functional dyspepsia and irritable colon.

Abstract
OBJECTIVES Proton pump inhibitor (PPI) therapy is a potentially modifiable risk factor for recurrent Clostridioides difficile infection (CDI). Citing an absence of clinical trials, many guidelines do not provide recommendations for addressing PPI management. Our aim was to perform an updated systematic review and meta-analysis evaluating the association between PPI use and recurrent CDI addressing prior methodological limitations. METHODS Data sources were MEDLINE and EMBASE. Eligible studies were cohort and case-control studies; there were no restrictions on study setting or duration of follow-up. Participants were adults with prior CDI who did or did not receive PPI therapy and were assessed for recurrent CDI. Summary (unadjusted) odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random effects model. Prespecified subgroup analyses were performed to explore heterogeneity including study design, study quality, duration of follow-up, adjustment for confounders, and outcome definition. RESULTS Sixteen studies were included in the meta-analysis, comprising 57 477 patients with CDI, of whom 6870 (12%) received PPIs. The rate of recurrent CDI was 24% in patients treated with PPIs versus 18% in those who were not. A meta-analysis that pooled unadjusted odds ratios demonstrated higher odds of recurrent CDI in patients who received PPIs (OR 1.69, 95%CI 1.46-1.96) versus those who did not. There was moderate heterogeneity between studies (I2 56%); however, a sensitivity analysis restricted to studies with 56 days of follow-up substantially reduced the heterogeneity (OR 1.59, 95%CI 1.36-1.85; I2 12%). An analysis restricted to multivariate studies that combined adjusted ORs also demonstrated higher odds of recurrent CDI in patients who received PPIs (OR 1.49, 95%CI 1.12-2.00). No publication bias was identified. CONCLUSIONS We found significantly higher odds of recurrent CDI among users of PPIs that persisted across multiple sensitivity analyses. These results support stronger recommendations for PPI stewardship at CDI diagnosis.

Abstract
Proton pump inhibitors (PPIs) are a risk factor for hospital-acquired Clostridium difficile infection (CDI). Much PPI use is inappropriate, and interventions to reduce PPI use, such as for stress ulcer prophylaxis in all critically ill patients, are essential to reduce CDI rates. This mixed-methods study in a combined medical-surgical intensive care unit at a tertiary academic medical center used a human factors engineering approach to understand barriers and facilitators to optimizing PPI prescribing in these patients. We performed chart review of patients for whom PPIs were prescribed to evaluate prescribing practices. Semistructured provider interviews were conducted to determine barriers and facilitators to reducing unnecessary PPI use. Emergent themes from provider interviews were classified according to the Systems Engineering Initiative for Patient Safety model. In our intensive care unit, 25% of PPI days were not clinically indicated. Barriers to optimizing PPI prescribing included inadequate provider education, lack of institutional guidelines for stress ulcer prophylaxis, and strong institutional culture favoring PPI use. Potential facilitators included increased pharmacy oversight, provider education, and embedded decision support in the electronic medical record. Interventions addressing barriers noted by front line providers are needed to reduce unnecessary PPI use, and future studies should assess the impact of such interventions on CDI rates.

External validation of two prediction tools for patients at risk for recurrent Clostridioides difficile infection. Therap Adv Gastroenterol 2021; 14:1756284820977385. [PMID: 33456500 PMCID: PMC7797589 DOI: 10.1177/1756284820977385] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 11/03/2020] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND One in four patients with primary Clostridioides difficile infection (CDI) develops recurrent CDI (rCDI). With every recurrence, the chance of a subsequent CDI episode increases. Early identification of patients at risk for rCDI might help doctors to guide treatment. The aim of this study was to externally validate published clinical prediction tools for rCDI. METHODS The validation cohort consisted of 129 patients, diagnosed with CDI between 2018 and 2020. rCDI risk scores were calculated for each individual patient in the validation cohort using the scoring tools described in the derivation studies. Per score value, we compared the average predicted risk of rCDI with the observed number of rCDI cases. Discrimination was assessed by calculating the area under the receiver operating characteristic curve (AUC). RESULTS Two prediction tools were selected for validation (Cobo 2018 and Larrainzar-Coghen 2016). The two derivation studies used different definitions for rCDI. Using Cobo's definition, rCDI occurred in 34 patients (26%) of the validation cohort: using the definition of Larrainzar-Coghen, we observed 19 recurrences (15%). The performance of both prediction tools was poor when applied to our validation cohort. The estimated AUC was 0.43 [95% confidence interval (CI); 0.32-0.54] for Cobo's tool and 0.42 (95% CI; 0.28-0.56) for Larrainzar-Coghen's tool. CONCLUSION Performance of both prediction tools was disappointing in the external validation cohort. Currently identified clinical risk factors may not be sufficient for accurate prediction of rCDI.

Abstract
Clostridioides difficile infection (CDI), formerly known as Clostridium difficile, continues to be the most common healthcare-associated infection worldwide. With the shifting epidemiology towards higher a incidence of community-acquired CDI and the continued burden on the healthcare system posed by high rates of CDI recurrence, there has been an impetus to advance the diagnostic testing and treatment strategies. Recent advancements over the past decade have led to rapidly changing guidelines issued by the Infectious Diseases Society of America and European Society of Clinical Microbiology and Infectious Diseases. With our comprehensive review, we aim to summarize the latest advances in diagnosing and treating CDI and thus attempt to help readers guide best practices for patient care. This article also focusses on cost-effectiveness of various therapies currently available on the market and provides an analysis of the current evidence on a relatively new monoclonal antibody therapy, Bezlotoxumab, to treat recurrent CDI.

Abstract
BACKGROUND Fecal microbiota transplantation (FMT) is highly effective for preventing recurrent Clostridioides difficile infection (CDI). Durability (no recurrence despite additional risk factor exposure) of FMT protection is largely unknown. We studied the durability of FMT in patients with recurrent CDI. METHODS We conducted a retrospective study of adults undergoing FMT for recurrent CDI. Data collected included demographics, CDI risk factors (comorbidities, healthcare exposure, non-CDI antibiotic use, acid suppressant medications), and future CDI episodes. Durable response to FMT was defined as lack of CDI episodes within 1 year post-FMT despite risk factor exposure. RESULTS Overall, 460 patients were included (median age, 57 years [18-94]; 65.2% female). Comorbidities included chronic liver disease, 12.8% (n = 59); cancer, 11.7% (n = 54); chronic kidney disease, 3.9% (n = 18); and inflammatory bowel disease, 21.9% (n = 101). Overall, 31.3% (n = 144) received antibiotics, 21.7% (n = 100) received acid suppressants, and 76.8% (n = 350) had healthcare exposure after FMT. Of 374 patients with risk factor exposure, 78.1% (95% confidence interval [CI], 72.7%-84.0%) had durable response to FMT at 1 year. On multivariable analysis, antibiotic use was independently associated with decreased durability of FMT (hazard ratio, 0.27; 95% CI, .15-.49; P < .001). CONCLUSIONS The majority of patients had a durable response to FMT despite exposure to CDI risk factors. Antibiotic exposure after FMT independently predicted loss of durability of FMT. Larger studies are needed to define predictors of durable response in patients with and without exposure to antibiotics.

Abstract
Proton pump inhibitors (PPIs) are commonly used for the treatment of gastric acid-related disorders, and are generally well tolerated. However, by reducing the secretion of gastric acid in the long term, PPI can increase the risk of inducing an imbalance in the gut microbiome composition. Moreover, gastric hypochlorhydria that is caused by PPIs favors the survival and migration of oral bacteria in the lower part of the gastrointestinal tract, with a possible induction of pro-inflammatory microenvironment. Therefore, gut dysbiosis that is associated with the use of PPI has been found to cause adverse infectious and inflammatory diseases. In this regard, adverse effects of the PPI-related gut dysbiosis have been reported in different observational studies, but their clinical relevance remains unclear. Therefore, the aim of this review was to explore the available data on the PPI-related gut dysbiosis in order to better understand its clinical significance.

Abstract
BACKGROUND Clostridioides difficile infection (CDI) is associated with poor outcomes in inflammatory bowel disease (IBD) patients. Data are scarce on efficacy of fecal microbiota transplant (FMT) for recurrent CDI in IBD patients. METHODS We reviewed health records of IBD patients (18 years of age or older) with recurrent CDI who underwent FMT. Outcomes of FMT for CDI were assessed on the basis of symptoms and stool test results. RESULTS We included 145 patients (75 women [51.7%]; median age, 46 years). Median IBD duration was 8 (range, 0-47) years, 36.6% had Crohn disease, 61.4% had ulcerative colitis, and 2.1% had indeterminate colitis. Median number of prior CDI episodes was 3 (range, 3-20), and 61.4% had received vancomycin taper. Diarrhea resolved after FMT in 48 patients (33.1%) without further testing. Ninety-five patients (65.5%) underwent CDI testing owing to post-FMT recurrent diarrhea; 29 (20.0%) had positive results. After FMT, 2 patients received empiric treatment of recurrent CDI without symptom resolution, suggesting IBD was the cause of symptoms. The overall cure rate of CDI after FMT was 80.0%, without CDI recurrence at median follow-up of 9.3 (range, 0.1-51) months. Forty-three patients (29.7%) had planned IBD therapy escalation after CDI resolution; none de-escalated or discontinued IBD therapy. Overall, 7.6% had worsening IBD symptoms after FMT that were treated as new IBD flares. No clinical predictors of FMT failure were identified. CONCLUSIONS Few patients had new IBD flare after FMT. Fecal microbiota transplantation effectively treats recurrent CDI in IBD patients but has no apparent beneficial effect on the IBD course.

Ribaxamase, an Orally Administered β-Lactamase, Diminishes Changes to Acquired Antimicrobial Resistance of the Gut Resistome in Patients Treated with Ceftriaxone. Infect Drug Resist 2020; 13:2521-2535.

Abstract
Introduction Intravenous (IV) β-lactam antibiotics, excreted through bile into the gastrointestinal (GI) tract, may disrupt the gut microbiome by eliminating the colonization resistance from beneficial bacteria. This increases the risk for Clostridium difficile infection (CDI) and can promote antimicrobial resistance by selecting resistant organisms and eliminating competition by non-resistant organisms. Ribaxamase is an orally administered β-lactamase for use with IV β-lactam antibiotics (penicillins and cephalosporins) and is intended to degrade excess antibiotics in the upper GI before they can disrupt the gut microbiome and alter the resistome. Methods Longitudinal fecal samples (349) were collected from patients who participated in a previous Phase 2b clinical study with ribaxamase for prevention of CDI. In that previous study, patients were treated with ceftriaxone for a lower respiratory tract infection and received concurrent ribaxamase or placebo. Extracted fecal DNA from the samples was subjected to whole-genome shotgun sequencing and analyzed for the presence of antimicrobial resistance (AMR) genes by alignment of sequences against the Comprehensive Antibiotic Resistance Database. A qPCR assay was also used to confirm some of the results. Results Database alignment identified ~1300 acquired AMR genes and gene variants, including those encoding β-lactamases and vancomycin resistance which were significantly increased in placebo vs ribaxamase-treated patients following antibiotic exposure. qPCR corroborated the presence of these genes and supported both new acquisition and expansion of existing gene pools based on no detectable copy number or a low copy number in pre-antibiotic samples which increased post-antibiotics. Additional statistical analyses demonstrated significant correlations between changes in the gut resistome and clinical study parameters including study drug assignment and β-lactamase and vancomycin resistance gene frequency. Discussion These findings demonstrated that ribaxamase reduced changes to the gut resistome subsequent to ceftriaxone administration and may help limit the emergence of AMR.

Abstract
Proton pump inhibitors (PPIs) are one of the most common medications taken by patients worldwide. PPIs are used to treat acid-related disorders, including gastroesophageal reflux disease, peptic ulcer disease, Helicobacter pylori infection, and nonsteroidal anti-inflammatory drug/stress ulceration. For some of these diseases, long-term treatment is necessary. With such prolonged use, concern and investigation into potential adverse effects has increased. In addition, data are available regarding potential anticancer effects of PPIs, especially regarding solid tumors. The aim of this review is to assess the literature on PPIs with regard to common concerns, such as drug-drug interactions, the intestinal microbiome, dementia and central nervous system disease, and osteoporosis, as well as to highlight potential negative and positive impacts of the drug in cancer.
