Filter by:Crohn's disease is an intestinal inflammatory disease, causing abdominal pain, diarrhea and other symptoms. The intestinal flora disorder is closely related to the occurrence and development of Crohn's disease. Acupuncture can induce remission of Crohn's disease during mild to moderate active period, improve clinical symptoms such as abdominal pain. This study is to screen the intestinal bacteria related to abdominal pain in CD, and explore the effects of acupuncture on the intestinal flora related to abdominal pain in CD patients.
Multidisciplinary techniques such as multimodal neuroimaging, microbiology, and bioinformatics were applied to study the differences in correlation characteristics between gut microbes, functional brain networks, and peripheral inflammation among patients with active Crohn's disease (CD), CD in remission, and healthy subjects.
Machine learning algorithms are applied to discover gut flora markers that predict the clinical efficacy of acupuncture, so as to screen the appropriate population for acupuncture and optimise the allocation of healthcare resources.
Aim of the study: To evaluate risk factors of endoscopic relapse after ileocolic resection in a cohort of Crohn's disease patients treated with anti-TNF agents. Methods: From 2014 to 2022, all consecutive patients who underwent ileocolic resection for Crohn's disease treated with anti-TNF agents in two referral tertiary center were prospectively collected. Considering exclusion criteria, data from 114 patients were analyzed. The cohort was separated into 2 groups according to study period. Short and long-term outcomes were compared between the two groups. Primary outcome: Endoscopic recurrence (defined as > i2 lesions according to Rutgeerts classification) 6 months after surgery
The loss of response rate of ustekinumab(UST) is high, and the specific mechanism has not yet been elucidated. Molecular markers that can accurately predict the efficacy of UST are urgently needed to provide theoretical basis for guiding individualized treatment. Therefore, this study intends to explore the impact of intestinal epithelial fucosylation levels on the efficacy of UST in patients with Crohn's disease(CD), aiming to provide predictable molecular markers for UST to accurately treat CD.
Bowel urgency is commonly defined as the sudden need to rush to the bathroom to empty one's bowel. In the field of inflammatory bowel disease (IBD) (including Crohn's disease (CD) and ulcerative colitis (UC)), bowel urgency is part of the top five research priorities for future IBD nursing research, and it is a symptom that patients consider to be most important when prioritizing their disease control. Urgency is a patient-reported outcome associated with compromised quality of life and future risk of hospitalizations, corticosteroids, and colectomy in patients with UC. A meta-analysis of 321 studies examining bowel urgency revealed that only one-third of these clinical studies clearly defined the concept of bowel urgency. Definition of bowel urgency was heterogeneous as 14 different definitions were identified. In most of these studies, non-validated questionnaires were used. They are based on subjective responses of the patients, and they could determine evaluation bias. These data emphasize the lack of standardization in bowel urgency assessment.
The objective of this trial is to test whether a smartphone app, SMART-IBD, is effective in improving medication adherence and self-management skills in adolescents with IBD. The investigators will conduct a randomized control trial to compare a sample of 15 youth (ages 13-17) with IBD using an app that has educational content and medication reminders to 15 youth in an attention control group. The length of the intervention will include one month of baseline adherence data collection, one month of intervention, and one month of post-treatment adherence data collection.
Methotrexate is one of the immunosuppressants used in chronic inflammatory bowel disease (IBD). It is indicated as monotherapy for induction and maintenance treatment of Crohn's disease (CD), or in combination with anti-tumor necrosis factor (TNF) agents for prevention of immunization. The main objective is to assess the persistence rate of methotrexate treatment in patients followed for chronic inflammatory bowel disease (IBD).
Inflammatory bowel disease (IBD) comprises a series of disorders of unknown cause, such as ulcerative colitis (UC), Crohn's disease (CD) and indeterminate colitis (IC), associated with an over-the-top immune response that produces lesions of variable depth and extent in the intestine. They have a chronic course, without cure and with an unpredictable evolution. Clinical symptoms of CD are characterized by malaise, weight loss, fever, diarrhoea, abdominal pain, vomiting, sometimes palpable mass, perianal disease, among others. The disease is most frequently located in the ileocecal area, but all the entire digestive tract from the oral cavity to the rectum may be affected. The involvement of the upper gastrointestinal tract (UGT) (L4) in CD is frequently undiagnosed. From 1-7% of patients with CD refer symptoms or signs that are due to UG involvement. Chronic iron deficient anaemia, in the absence of digestive symptoms, is the only guiding sign that may alert about the diagnosis. Furthermore, retrospective cohort studies suggest that CD of the UGT is associated with a worse prognosis. The systematic study of the UGT in the initial evaluation of CD at the time of diagnosis is not generally recommended in adulthood, European Crohn's and Colitis Organisation (ECCO) guidelines recommend upper endoscopy only if there are upper digestive symptoms (vomiting, dyspepsia, etc.). In the case of gastroscopy, gastric biopsies have to be performed due to the possible presence of focal active gastritis, which is considered very specific of CD. This statement is based on a limited series of cases published in 1980. On the other hand, systematic performance of duodenal biopsies is not recommended. This fact has caused that the histopathology of duodenal CD is very unknown and the need to perform duodenal biopsies of the UGT is still a matter of debate. Macro and microscopic findings from the UGT have generally been used to differentiate between UC and CD in cases of IC. Among the macroscopic findings highlight the presence of sores or ulcers and most specific and frequent microscopic findings are granulomas and chronic inflammatory infiltrate respectively. However, it is known that CD can cause lymphocytic infiltration of the duodenal epithelium (duodenal lymphocytosis or lymphocytic enteritis) and villus atrophy. These are findings are characteristically found in celiac disease, and therefore, these histological lesions of the duodenum also propose the differential diagnosis between celiac disease and CD. In addition, it must be considered that many of the patients with IBD take immunosuppressive for disease control, which have been reported to be the cause of lymphocytic enteritis and duodenal villus atrophy. This proposed drug-induced enteropathy is based only in a few series of cases in the context of treatment with azathioprine and methotrexate. There are no studies systematically evaluate how often these drugs can cause a "sprue like" enteropathy. The lymphocytic enteritis of celiac disease has been associated with a specific pattern of lymphocyte subpopulations (increase in the percentage of CD3+TCRγẟ+ lymphocytes and decrease in the percentage of CD3-). It is unknown if CD duodenal lymphocytes is associated with a specific CD cytometric pattern. If so, the evaluation of lymphocyte subpopulations could be of great diagnostic aid when considering the differential diagnosis between celiac disease, CD and other forms of duodenal lymphocytosis.
It is uncertain whether vitD3 supplementation is beneficial for the remission of Crohn's disease (CD). The effects of vitD3 supplements on the efficacy of ustekinumab in Chinese CD patients were retrospectively analyzed. Methods: Patients with moderate to severe CD were recorded. These patients were initially treated with UST. VitD3 supplementation was defined as 400IU/d vitD3 supplementation during the first infusion of UST and continued throughout the follow-up period. Disease activity was assessed using Harvey Bradshaw Index.
