Background: Inflammatory bowel diseases with an early-onset form (EO-IBDs) make up a special disease group with certain clinical and phenotypic characteristics. This article discusses the features of such early onset in a group of children, based on five years of monitoring a registry of children with IBD from a specialized center. Methods: This retrospective single-center cohort study included pediatric patients diagnosed with EO-IBD between 2019 and 2024. Clinical, laboratory, and endoscopic data were collected from medical records, including fecal calprotectin, inflammatory markers, disease activity indices, and endoscopic severity scores. Localization was classified according to the Paris system, and histological activity was assessed using the IBD-DCA score. Results: There were 20 patients with ulcerative colitis (UC) and 17 with Crohn’s disease (CD). Clinical activity was moderate or high (p = 0.179). UC was more characterized by diarrhea and rectal bleeding. CD was more often accompanied by abdominal pain, weight loss, and fever. In total, 82.4% of patients with CD had an inflammatory form. UC-like intestinal lesion was typical of both nosologies—L3 64.7% and E4 60% forms in CD and UC, respectively. Morphological activity was moderate for both nosologies (p = 0.54). IBD-U was present in 43.2% of patients. The median time after which it was possible to diagnose UC was 24 weeks (IQR 20–48) and 40 weeks (IQR 30–45.5) for CD (p = 0.56). Conclusions: Our study confirms the presence of characteristic signs of EO-IBD development, such as a frequent family history of IBD, high or moderate clinical activity during diagnosis verification, colon damage, and a high frequency of extraintestinal manifestations.

Background/Objectives: Pediatric inflammatory bowel disease (pIBD), including Crohn’s disease (CD), ulcerative colitis (UC), and IBD-unclassified (IBD-U), exhibits unique clinical features compared to adult-onset disease. This study aimed to describe phenotypic characteristics of pIBD in the north-west region of Romania over a 21-year period and to compare our findings with those of other studies worldwide. Methods: We conducted a retrospective study of children under 18 years of age, from the north-west region of Romania, diagnosed with pIBD between 2000 and 2020 at the Emergency Clinical Hospital for Children, Cluj-Napoca. Disease phenotype at diagnosis was established according to the Paris classification. Data were collected from the hospital records and analyzed using descriptive statistics and univariate analysis of categorical variables. A p-value < 0.05 was considered statistically significant. Results: Ninety-four patients were included (CD: 51.0%; UC: 43.6%; IBD-U: 5.4%), with a median age at diagnosis of 14 years (11–15.7). Very early-onset IBD accounted for 5.3% of cases. The likelihood of being diagnosed with CD after 10 years of age was significantly higher compared to UC (OR = 4.75, 95% CI: 1.10–29.07, p = 0.03). UC most frequently presented as pancolitis (51.2%), while CD most often involved the ileocolonic region (56.3%). Inflammatory behavior was the most common CD phenotype (69%). Upper gastrointestinal involvement was documented in 18.7% of CD cases, with detection rates increasing after 2014. Perianal disease and growth impairment were significantly associated with complicated CD behavior (p = 0.03, and p = 0.007 respectively). Our findings are broadly consistent with other published reports. Conclusions: This study provides the first detailed phenotypic characterization of pIBD in this region. Our findings reflect trends observed in other populations and underscore the importance of standardized diagnostic evaluation. Full article

Inflammatory bowel diseases (IBDs), including Crohn’s disease (CD), ulcerative colitis (UC), and IBD-unclassified (IBD-U), are chronic inflammatory disorders of the gastrointestinal tract. Chronic inflammation in the course of IBD is an important initiating factor of fibrosis of the intestinal wall. Intestinal fibrosis is one of the most common and important complications of IBD and, due to the irreversibility of the process and the need for surgical treatment, currently poses a major clinical challenge. In this review, we presented in detail the process of intestinal wall fibrosis at the molecular, immunological, and clinical levels. We characterized the mediators, including transforming growth factor β (TGF-β), tumor necrosis factor-α (TNF-α), and others participating in this process. We also described the type 2 epithelial–mesenchymal transition (EMT) process closely associated with chronic inflammation, leading to excessive development of connective tissue in the intestinal wall in the course of IBD.

Background: Chronic inflammatory bowel disease significantly impacts patients’ everyday lives. Despite receiving regular medical care in gastroenterological or family medicine consultations, patients with inflammatory bowel disease (IBD) still experience a lack of information. To evaluate these deficits, we analyzed the main points of interest raised in an online consultation forum offered as a supplementary resource for patients. Methods: We analyzed 20 years of online consultation data at three time points, 2003 (launch of the forum), 2013, and 2024, and compared them against each other. A total of 681 patients participated in the consultations during these years. The clinical profiles of the participants included Crohn’s disease (CD, n = 209), ulcerative colitis (UC, n = 140), unclassified colitis (IBDU, n = 30), and individuals with no specified diagnosis (NSD, n = 303). Results: Patients with ulcerative colitis demonstrated interest in topics such as diet and nutrition, as well as treatment with biologics. Patients with Crohn’s disease expressed interest in diet, nutritional management, and treatment with biologics. Additionally, they showed interest in pain management, diagnostic imaging, and stress management. In the case of patients with unclassified colitis, a broad range of topics was addressed, with no single area emerging as particularly prominent. Patients with no specified diagnosis exhibited interest in diet and nutrition, laboratory diagnostics, and pain therapy. Conclusions: For patients with inflammatory bowel disease, online consultations represent a valuable complement to standard medical care. They provide additional support and contribute to enhancing patients’ confidence in managing their condition. A broad spectrum of disease-related topics was addressed during the consultations. Identified information gaps can be systematically discussed and subsequently reduced. Full article

Inflammatory bowel disease (IBD), encompassing Crohn’s disease (CD), ulcerative colitis (UC), and IBD unclassified (IBD-U), is a complex intestinal disorder influenced by genetic, environmental, and microbial factors. Recent evidence highlights the gut microbiota as a pivotal biomarker and modulator in IBD pathogenesis. Dysbiosis, characterized by reduced microbial diversity and altered composition, is a hallmark of IBD. A consistent decrease in anti-inflammatory bacteria, such as Faecalibacterium prausnitzii, and an increase in pro-inflammatory species, including Escherichia coli, have been observed. Metabolomic studies reveal decreased short-chain fatty acids (SCFAs) and secondary bile acids, critical for gut homeostasis, alongside elevated pro-inflammatory metabolites. The gut microbiota interacts with host immune pathways, influencing morphogens, glycosylation, and podoplanin (PDPN) expression. The disruption of glycosylation impairs mucosal barriers, while aberrant PDPN activity exacerbates inflammation. Additionally, microbial alterations contribute to oxidative stress, further destabilizing intestinal barriers. These molecular and cellular disruptions underscore the role of the microbiome in IBD pathophysiology. Emerging therapeutic strategies, including probiotics, prebiotics, and dietary interventions, aim to restore microbial balance and mitigate inflammation. Advanced studies on microbiota-targeted therapies reveal their potential to reduce disease severity and improve patient outcomes. Nevertheless, further research is needed to elucidate the bidirectional interactions between the gut microbiome and host immune responses and to translate these insights into clinical applications. This review consolidates current findings on the gut microbiota’s role in IBD, emphasizing its diagnostic and therapeutic implications, and advocates for the continued exploration of microbiome-based interventions to combat this debilitating disease.

Background and Objectives: Ulcerative colitis (UC) and Crohn’s disease (CD) are idiopathic inflammatory bowel diseases (IBDs) without a unique, gold standard diagnostic test. UC and Crohn’s colitis are impossible to distinguish in approximately 10% of cases. The term IBD type unclassified (IBD-U) is recommended for cases of chronic colitis showing overlapping endoscopic, radiological, and biopsy histological features between UC and CD, while indetermined colitis is reserved for colectomy specimens. Our aim was to assess the role of small-bowel capsule endoscopy (SBCE) in the diagnostic work-up of IBD-U. Materials and Methods: We retrospectively studied the cases of IBD-U explored by SBCE in a tertiary referral gastroenterology center. Patients were investigated using SBCE after contraindications were excluded. Diagnostic criteria for small bowel CD consisted in more than three ulcerations, irregular ulcers, or stenosis, and the Lewis score was used for the quantification of inflammation. The immediate impact of reclassification and outcome data was recorded over a follow-up period of more than one year. Results: Twenty-eight patients with IBD-U were examined using SBCE. Nine patients had small bowel lesions that met the diagnostic criteria for CD, resulting in a reclassification rate of 32.1%. In five of these cases, the treatment was subsequently changed. In the remaining nineteen examinations, no significant findings were observed. There were no complications associated with SBCE. Median follow-up time was 32.5 months (range 12–60). During follow-up, twelve patients were classified as having UC, and seven remained as having an unclassified type; one case of colectomy, for medically refractory UC, was recorded. Conclusions: SBCE is a useful safe tool in the work-up of IBD-U, allowing reclassification in about one third of cases, with subsequent treatment modifications. SBCE may provide a definite diagnosis, enhance the comprehension of the disease’s progression, and optimize the short- and long-term management strategy. Full article

Antibody testing in inflammatory bowel disease (IBD) can add to diagnostic accuracy of the main subtypes Crohn’s disease (CD) and ulcerative colitis (UC). Whether modern modeling techniques such as supervised and unsupervised machine learning are of value for finer distinction of subtypes such as IBD-unclassified (IBD-U) is not known. We determined the antibody profile of 100 adult IBD patients from the Swiss IBD cohort study with known subtype (50 CD, 50 UC) as well as of 76 IBD-U patients. We included ASCA IgG and IgA, p-ANCA, MPO- and PR3-ANCA, and xANCA measurements for computing different antibody panels as well as machine learning models. The AUC of an optimized antibody panel was 85% (95%CI, 78–92%) to distinguish CD from UC patients. The antibody profile of IBD-U patients was closely related to UC. No specific antibody profile was predictive for IBD-U nor for re-classification. The panel diagnostic was in favor of UC reclassification prediction with a correct assignment rate of 69.2–73.1% depending on the cut-off applied. Supervised machine learning could not distinguish between CD, UC, and IBD-U. More so, unsupervised machine learning suggested only two distinct clusters as a likely number of IBD subtypes. Antibodies in IBD are supportive in confirming clinical determined subtypes CD and UC but have limited capacity to predict IBD-U and reclassification during follow-up. In terms of antibody profiles, IBD-U is not a distinct subtype of IBD. Full article

Introduction: Patients with Inflammatory Bowel Disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), are at high risk of developing malignancies, so prevention and adherence to cancer screening may improve detection. The aim of this study was to assess compliance with medical recommendations, especially primary and secondary prevention of cancer. Methods: This one-center cross-sectional study was carried out between June and December 2021 amongst patients at the Department of Internal Medicine and Gastroenterology, IBD Division, National Medical Institute of Ministry of Interior Affairs and Administrations, or the outpatient clinic. Patients with IBD were asked to complete an anonymous questionnaire, which included 42 questions concerning lifestyle, cancer risk factors, cancer history, and checkups. Statistical methods: The results of the qualitative variables were expressed as frequencies and percentages. We used Fisher’s exact test and the Chi-squared test. A value of p < 0.05 was considered significant. Statistical analyses were performed with the SPSS statistical package. Results: A total of 313 patients were enrolled in the study: 145 women and 168 men. In the group, 182 had Crohn’s disease (CD), 120 had ulcerative colitis (UC), and 11 with IBDU (unclassified IBD). Most participants had a disease duration of over 8 years and received biological treatment, corticoids, and/or immunosuppressive therapy. Amongst respondents, 17% (31) of patients with CD and 25.8% (31) with UC were overweight, and 10.5% (19) with CD and 15.8% (19) with UC were obese (p = 0.017). We found that 16.3% of all respondents were smokers (79.6% (144) with CD, 90.8% (109) with UC, and 72.7% (8) with IBDU; p = 0.053), and 33.9% declared that they consumed alcohol (39.4% (71) with CD, 26.9% (32) with UC, and 18.2% (2) with IBDU; p = 0.045). A total of 25.4% of patients were exposed to UV radiation, but only 18.8% used sunblock. In addition, 58.8% (67) of patients with CD and 35.8% (19) with UC receiving immunosuppressants had regular laboratory tests (p = 0.02). Furthermore, 41.4% (46) of patients with UC, 27.1% (49) of patients with CD, and 70.0% (7) of patients with IBDU declared not to perform any dermatological control (p = 0.013). A total of 77% of patients had abdominal ultrasound. Out of 52.9% of patients for whom colonoscopy was recommended, only 27.3% had it performed (16.9% (30) with CD vs. 43.1% (50) with UC p < 0.001). Most examinations were ordered by gastroenterologists. Female patients had regular breast control (CD, 78.6% (66); UC, 91.2% (52); IBDU, 50% (2); p = 0.034), and 93.8% (76) had gynecological examinations. Additionally, 80.2% of patients knew about HPV, but most declared not to be vaccinated. A total of 17.9% of patients had urological control, but most had no important pathology detected. Conclusions: According to our study, many patients are still exposed to risk factors, such as obesity, smoking, and low physical activity, that are modifiable. Laboratory tests in patients with immunosuppressive treatment should be performed regularly. Systematic control, especially dermatological checkups, should be recommended. Additionally, not only gastrologists but also other specialists and GPs should remind patients about regular checkups. Primary prevention, such as HPV vaccinations, should be recommended to all patients. Full article

Inflammatory bowel diseases (IBDs) are chronic relapsing inflammatory conditions of the gastrointestinal tract, encompassing Crohn’s disease (CD), ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBD-U). They are currently considered as systemic disorders determined by a set of genetic predispositions, individual susceptibility and environmental triggers, potentially able to involve other organs and systems than the gastrointestinal tract. A large number of patients experiences one or more extraintestinal manifestations (EIMs), whose sites affected are mostly represented by the joints, skin, bones, liver, eyes, and pancreas. Pancreatic abnormalities are not uncommon and are often underestimated, encompassing acute and chronic pancreatitis, autoimmune pancreatitis, exocrine pancreatic insufficiency and asymptomatic elevation of pancreatic enzymes. In most cases they are the result of environmental triggers. However, several genetic polymorphisms may play a role as precipitating factors or contributing to a more severe course. The aim of this paper is to provide an updated overview on the available evidence concerning the etiology, pathogenesis and clinical presentation of pancreatic diseases in IBD pediatric patients.

(1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD—Crohn’s disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)—during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31–56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery. Full article
