[PMID: 38676422 DOI: 10.1080/14787210.2024.2347955] [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: 03/14/2023] [Accepted: 04/23/2024] [Indexed: 04/28/2024]
Abstract
INTRODUCTION Strong clinical data demonstrate that inflammatory bowel disease (IBD) is an independent risk factor for Clostridiodes difficile infection (CDI) and suggest a globally increased prevalence and severity of C. difficile coinfection in IBD patients (CDI-IBD). In addition to elderly individuals, children are also at higher risk of CDI-IBD. Rapid diagnosis is essential since the clinical manifestations of active IBD and CDI-IBD are indistinguishable. Antibiotics have been well established in the treatment of CDI-IBD, but they do not prevent recurrence. AREAS COVERED Herein, the authors focus on reviewing recent research advances on the new therapies of CDI-IBD. The novel therapies include gut microbiota restoration therapies (such as prebiotics, probiotics and FMT), immunotherapy (such as vaccines and monoclonal antibodies) and diet strategies (such as groningen anti-inflammatory diet and mediterranean diet). Future extensive prospective and placebo-controlled studies are required to evaluate their efficacy and long-term safety. EXPERT OPINION Available studies show that the prevalence of CDI-IBD is not optimistic. Currently, potential treatment options for CDI-IBD include a number of probiotics and novel antibiotics. This review updates the knowledge on the management of CDI in IBD patients, which is timely and important for GI doctors and scientists.

Abstract
Iron is arguably the most important nutrient in the ongoing battle between hosts and bacteria. Recently in Nature, a unique iron storage organelle, the ferrosome, was discovered in the human pathogen Clostridioides difficile.1 But what is the role of ferrosomes and how do they affect bacterial behavior and infection?

Abstract
PURPOSE OF REVIEW Children with inflammatory bowel disease (IBD) are at increased risk of C. difficile infection (CDI) and experience worse outcomes associated with an infection. In this article, we review recent research on the incidence, diagnosis, complications, and treatment options for CDI in children with IBD. RECENT FINDINGS Children with IBD have an elevated incidence of CDI, but their CDI risk does not associate with established risk factors in adults with IBD. Existing testing methodologies are inadequate at differentiating CDI from C. difficile colonization in children with IBD. Fecal microbiota transplantation offers a durable cure for recurrent CDI. CDI remains a frequent occurrence in children with IBD. Careful clinical monitoring should be used to diagnose CDI and patients with co-occurring IBD and CDI require careful surveillance for worse outcomes. Future research should explore the optimal diagnosis and treatment modalities in this unique patient population.

Abstract
Background The prevalence of Clostridium difficile infection (CDI) as a common complication among inflammatory bowel disease (IBD) has been reported to increase worldwide and has been associated with a poor IBD outcome. Objectives In this study, our aim was to report on the prevalence of CDI among IBD vs. non-IBD patients in King Abdulaziz Medical City (KAMC). Methods This retrospective descriptive study was carried out between 2016 and 2020. Data of 89 patients reported with CDI in KAMC were analyzed for demographics and correlations between various characteristics such as BMI, personal/family history of IBD, infection with CDI, diagnosis, method of diagnosis, and treatment modalities. Results Of the total 89 CDI patients, 59 (66.3%) were adults and 30 (33.7%) were pediatric, of which 36 (40.4%) were females and 53 (59.6%) were males. PCR was the main method of choice for the diagnosis of CDI (89.9%) followed by a positive-culture result (10.0%). Seventy-eight (87.6%) CDI patients were found to be immunocompromised, with two patients diagnosed with IBDs, one with UC, and one with CD. The recurrence rate was 38.4 (30 patients) among the immunocompromised group in comparison to 27.2 (3 patients) in the immunocompetent group (p=0.584). Conclusion In this study, we found that adults were more prone to CDI infection, especially within hospital settings, and most of the CDI infections occurred in immunocompromised individuals, with cancer as the most common cause of it.

Abstract
(1) Background: The Global Leadership Initiative on Malnutrition (GLIM) was published in 2019, and its application has been explored in several diseases. However, the data on malnutrition based on the GLIM in ulcerative colitis (UC) patients are sparse. (2) Methods: This single-center, retrospective cohort study included 605 hospitalized UC patients. Demographics and clinical data were collected from electronic medical records. Nutritional Risk Screening 2002 (NRS 2002) was used as a screening tool, and malnutrition was diagnosed according to the GLIM criteria. The skeletal muscle area of the third lumber cross-section in abdominal computed tomography was used to evaluate muscle mass within one week before or after admission. (3) Results: The prevalence of malnutrition was 64.1% in this cohort, and the prevalences were 34.2, 57.7, and 86.7% in UC patients with mild, moderate, and severe disease activity, respectively. Malnourished patients tended to need surgical treatment (p = 0.080) and had a 2.4 times greater risk of opportunistic infection. The multivariate logistic regression analysis showed that UC patients with malnutrition had a 1.7-fold increased risk of readmission. (4) Conclusions: Nutritional problems deserve more attention in hospitalized UC patients. Malnutrition identified through the GLIM criteria was associated with opportunistic infection, tended to be associated with surgical treatment, and showed a prognosis value for readmission.

Fettucciari K, Dini F, Marconi P, Bassotti G. Role of the Alteration in Calcium Homeostasis in Cell Death Induced by Clostridioides difficile Toxin A and Toxin B. BIOLOGY 2023; 12:1117. [PMID: 37627001 PMCID: PMC10452684 DOI: 10.3390/biology12081117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 08/05/2023] [Accepted: 08/08/2023] [Indexed: 08/27/2023]
Abstract
Clostridioides difficile (C. difficile), responsible for 15-25% of gastrointestinal infections, causes health problems mainly due to the toxic activity of toxins A and B (Tcds). These are responsible for its clinical manifestations, including diarrhea, pseudomembranous colitis, toxic megacolon and death, with a mortality of 5-30% in primary infection, that increase following relapses. Studies on Tcd-induced cell death have highlighted a key role of caspases, calpains, and cathepsins, with involvement of mitochondria and reactive oxygen species (ROS) in a complex signaling pathway network. The complex response in the execution of various types of cell death (apoptosis, necrosis, pyroptosis and pyknosis) depends on the amount of Tcd, cell types, and Tcd receptors involved, and could have as initial/precocious event the alterations in calcium homeostasis. The entities, peculiarities and cell types involved in these alterations will decide the signaling pathways activated and cell death type. Calcium homeostasis alterations can be caused by calcium influx through calcium channel activation, transient intracellular calcium oscillations, and leakage of calcium from intracellular stores. These increases in cytoplasmic calcium have important effects on all calcium-regulated molecules, which may play a direct role in several cell death types and/or activate other cell death effectors, such as caspases, calpains, ROS and proapoptotic Bcl-2 family members. Furthermore, some support for the possible role of the calcium homeostasis alteration in Tcd-induced cell death originates from the similarity with cytotoxic effects that cause pore-forming toxins, based mainly on calcium influx through plasma membrane pores.

Abstract
Clostridioides difficile (C. difficile) is responsible for a high percentage of gastrointestinal infections and its pathological activity is due to toxins A and B. C. difficile infection (CDI) is increasing worldwide due to the unstoppable spread of C. difficile in the anthropized environment and the progressive human colonization. The ability of C. difficile toxin B to induce senescent cells and the direct correlation between CDI, irritable bowel syndrome (IBS), and inflammatory bowel diseases (IBD) could cause an accumulation of senescent cells with important functional consequences. Furthermore, these senescent cells characterized by long survival could push pre-neoplastic cells originating in the colon towards the complete neoplastic transformation in colorectal cancer (CRC) by the senescence-associated secretory phenotype (SASP). Pre-neoplastic cells could appear as a result of various pro-carcinogenic events, among which, are infections with bacteria that produce genotoxins that generate cells with high genetic instability. Therefore, subjects who develop IBS and/or IBD after CDI should be monitored, especially if they then have further CDI relapses, waiting for the availability of senolytic and anti-SASP therapies to resolve the pro-carcinogenic risk due to accumulation of senescent cells after CDI followed by IBS and/or IBD.

Abstract
Crohn's disease (CD) is a type of inflammatory bowel disease (IBD) characterized by chronic transmural inflammation of any portion of the gastrointestinal tract. The etiology of CD remains unknown although genetic, immunological, and acquired factors have been recognized as contributing to its development. Alterations of intestinal microbiota, including Clostridioides difficile (C. difficile), are theorized to alter humoral immunity and contribute toward CD flare pathogenesis. As such, cases of IBD remission can be undone by alterations in the gut microbiota and subsequently confound the diagnosis of inflammatory or infectious etiologies of diarrhea. We present a case of a 73-year-old female with dormant CD for 25 years who experienced an atypical course of diarrhea found to have a CD flare in the setting of acute C. difficile colitis.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) patients are at risk for Clostridioides difficile infection (CDI). The majority of published outcomes data feature medically treated patients. We aimed to analyze outcomes in a large cohort of surgical IBD patients diagnosed with CDI. METHODS All patients with IBD in the ACS NSQIP Colectomy and Proctectomy (2015-2019) modules were identified. The IBD-CDI and IBD cohorts were propensity score weighted on demographic and surgical factors and compared. RESULTS In the entire unmatched cohort (n = 12,782), 119/0.93% patients were diagnosed with CDI (74.2% Crohn's/25.7% UC/Indeterminate colitis) within 30-days of surgery. After propensity score weighting, IBD-CDI was associated with increased risk of readmission (OR 4.55 [3.09-6.71], p < 0.001), reoperation (3.17 [1.81-5.52], p < 0.001) and any complication (2.16 [1.47-3.17], p < 0.001). Any SSI (2.58 [1.67-3.98]), organ space SSI (2.49 [1.51-4.11], both p < 0.001), prolonged ventilation (4.03 [1.39-11.69],p = 0.01), acute renal failure (15.06 [4.26-53.26],p < 0.001), stroke (12.36 [1.26-121.06],p = 0.03), sepsis (2.4 [1.39-4.15],p = 0.002) and septic shock (3.29 [1.36-7.96],p = 0.008) were also higher in the IBD-CDI cohort. Mean length of stay was increased by 39% in CDI patients. CONCLUSION Post colonic resection, IBD-CDI patients have worse outcomes than IBD patients without CDI. These patients represent a particularly vulnerable cohort who require close monitoring for the development of postoperative complications.

Abstract
Inflammatory bowel disease (IBD), comprising Crohn's disease and ulcerative colitis, is a chronic inflammatory condition of the gastrointestinal tract, which is often accompanied by altered gut microbial composition. Gut dysbiosis in IBD is considered to be the reason for the high risk of Clostridioides difficile infection (CDI) in patients with IBD. Therefore, CDI should be evaluated in IBD patients with a symptom flare. Medical treatment of non-severe CDI in IBD is similar to that in non-IBD patients and includes oral vancomycin or fidaxomicin. The risk of recurrent CDI in IBD is higher than in non-IBD patients and this could be mitigated by fecal microbiota transplantation. As CDI may worsen the clinical outcomes of IBD, patients should be carefully monitored and an escalation of IBD therapy needs to be considered when there is no improvement seen with the antimicrobial treatment of CDI. This review discusses the risk, pathophysiology, diagnosis, and management of CDI in IBD.

Abstract
Clostridioides difficile (C. difficile) represents a major health burden with substantial economic and clinical impact. Patients with inflammatory bowel diseases (IBD) were identified as a risk category for Clostridioides difficile infection (CDI). In addition to traditional risk factors for C. difficile acquisition, IBD-specific risk factors such as immunosuppression, severity and extension of the inflammatory disease were identified. C. difficile virulence factors, represented by both toxins A and B, induce the damage of the intestinal mucosa and vascular changes, and promote the inflammatory host response. Given the potential life-threatening complications, early diagnostic and therapeutic interventions are required. The screening for CDI is recommended in IBD exacerbations, and the diagnostic algorithm consists of clinical evaluation, enzyme immunoassays (EIAs) or nucleic acid amplification tests (NAATs). An increased length of hospitalization, increased colectomy rate and mortality are the consequences of concurrent CDI in IBD patients. Selection of CD strains of higher virulence, antibiotic resistance, and the increasing rate of recurrent infections make the management of CDI in IBD more challenging. An individualized therapeutic approach is recommended to control CDI as well as IBD flare. Novel therapeutic strategies have been developed in recent years in order to manage severe, refractory or recurrent CDI. In this article, we aim to review the current evidence in the field of CDI in patients with underlying IBD, pointing to pathogenic mechanisms, risk factors for infection, diagnostic steps, clinical impact and outcomes, and specific management.

OBJECTIVE Patients with inflammatory bowel disease (IBD) are susceptible to Clostridioides difficile infection (CDI), resulting in poor outcomes and recurrence; therefore, the molecular characterization of C. difficle in IBD patients in China needs further investigation. METHODS C. difficile strains were isolated and identified from fecal samples of adult and pediatric IBD patients. Toxigenic strains were typed using multilocus sequence typing (MLST) and whole genomic sequencing (WGS) to construct the phylogenetic tree. Susceptibility to 10 antimicrobials was evaluated using the E-test. RESULTS Among the 838 IBD patients, 82 toxigenic C. difficile were identified, which comprised 46 from adults and 36 children. 90.2% (74/82) of the isolates were positive for both toxin A and toxin B genes (A+B+), while the remaining 9.8% were negative for toxin A gene, but positive for toxin B gene (A-B+). These toxigenic strains were susceptible to metronidazole and vancomycin, but highly resistant to clindamycin, erythromycin, and fluoroquinolones. All moxifloxacin-resistant isolates had mutations resulting in an amino acid substitution in gryA (T82I). The dominant types were ST-35 (20.7%), ST-2 (17.1%), ST-54 (13.4%), and ST-3 (13.4%) in all patients. CONCLUSION The incidence and molecular epidemiology of C. difficile infection in adult IBD patients resembled CDI in the general inpatient population. A higher antibiotic resistance rate was identified among the C. difficile isolates obtained from pediatric IBD patients than adult patients, and few STs accounted for most multidrug-resistant strains. However, the molecular genetic features of the same ST-type between these two groups remains highly correlated.

Abstract
Crohn's disease is a chronic inflammatory disease that can affect any portion of the gastrointestinal tract. Associated symptoms can vary based on the severity of disease, extent of involvement, presence of extraintestinal manifestations, and development of complications. Diagnosis is based on a constellation of findings. Many diseases can mimic Crohn's disease and lead to diagnostic conundrums. These include entities associated with the gastrointestinal luminal tract, vascular disease, autoimmune processes, various infections, malignancies and complications, drug- or treatment-induced conditions, and genetic diseases. Careful consideration of possible causes is necessary to establish the correct diagnosis.

Clin Infect Dis 2022; 74:793-801. [PMID: 34156442 DOI: 10.1093/cid/ciab567] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND Immunosuppressant exposure is associated with risk for Clostridioides difficile infection (CDI). It is unknown whether this risk is shared equally across immunosuppressant classes. METHODS This was a retrospective cohort study. Adults were included if they were tested for community-acquired CDI (CA-CDI) by stool polymerase chain reaction within 72 hours of hospitalization between 2010 and 2019. The primary outcome was CA-CDI requiring hospitalization, defined as a positive stool test. The primary exposure was use of a home immunosuppressant, at any dose or duration, defined based on the medication reconciliation, and categorized as systemic steroids, calcineurin inhibitors, antimetabolites, anti-tumor necrosis factor-alpha agents, anti-CD20 antibody, and all others. RESULTS A total of 10 992 hospitalized patients met criteria for the study including 1793 (16%) with CA-CDI; 23% used 1 or more immunosuppressant class. Among those immunosuppressed, 27% tested positive for CA-CDI compared with 22% among those who were not immunosuppressed (P < .01). After adjustment, calcineurin inhibitors (adjusted odds ratio [aOR], 1.19; 95% confidence interval [CI], 1.01-1.44) were associated with increased risk for CA-CDI. Risk for CA-CDI rose with multiple immunosuppressant classes: aOR, 1.22; aOR, 1.53; and aOR, 2.40 for 2, 3, and 4 classes, respectively. After excluding those with solid organ transplant, the relationship between use of calcineurin inhibitors and CDI increased (aOR, 2.21; 95% CI, 1.40-3.49). CONCLUSIONS The greatest risk for CA-CDI was observed among patients using multiple classes of immunosuppressants and those using calcineurin inhibitors. Future studies should recognize that CDI risk differs based on immunosuppressant class.

Clostridioides difficile Infection in Patients with Inflammatory Bowel Disease May be Favoured by the Effects of Proinflammatory Cytokines on the Enteroglial Network.

Abstract
Clostridioides difficile infection is widespread throughout countries and represents an important cause of nosocomial diarrhoea, with relatively high morbidity. This infection often occurs in patients with inflammatory bowel diseases and may complicate their clinical picture. Here, we propose, on the basis of evidence from basic science studies, that in patients affected by inflammatory bowel diseases, this infection might be facilitated by a derangement of the enteric glial cell (EGC) network caused by the effects of proinflammatory cytokines, such as tumour necrosis factor alpha and interferon gamma, which enhance the cytotoxic effects of C. difficile toxin B on EGCs. This hypothesis, if confirmed, could open the door to alternative treatment approaches to fight C. difficile infection.
