Inflammatory bowel disease

Inflammatory bowel disease (IBD) is a frequently occurring disease that seriously influences the patient's quality of life. To decrease adverse effects and improve efficacy of therapeutics, nanomedicines have been widely used to treat IBD. However, how to thoroughly release payloads under an inflammatory microenvironment and synergistic therapy of IBD need to be further investigated. To address this issue, cyclosporine A (CsA)-loaded, folic acid (FA)-modified, pH and reactive oxygen species (ROS) dual-responsive nanoparticles (FA-CsA NPs) were fabricated using pH/ROS-responsive material as carrier...

Background: Inflammatory bowel disease (IBD) affects all ages and backgrounds, and many individuals require surgical intervention during their disease course. The adoption of laparoscopic techniques in this patient population has been slow, including intracorporeal anastomosis (ICA). The aim of our study was to determine if ICA was feasible and safe in patients with IBD undergoing laparoscopic right hemicolectomy (LRHC). Methods: This is a retrospective, single institution cohort study of elective and emergent cases of LRHC at a single academic center...

We aimed to identify when magnetic resonance imaging (MRI) would be useful to diagnose patients with suspected axial spondyloarthropathy (AxSpA) without evidence of sacroiliitis on radiographs. We retrospectively reviewed electronic medical records of patients who underwent pelvis MRI after radiographs at the rheumatology clinic in a single tertiary center in Korea. Patients underwent imaging from January 2020 to July 2022. We collected data including complete blood count, erythrocyte sedimentation rate, C-reactive protein (CRP), human leukocyte antigen (HLA)-B27, history of acute anterior uveitis (AAU), peripheral arthritis, dactylitis, inflammatory bowel disease (IBD), enthesopathy, and psoriasis...

Aeromonas species are emerging human enteric pathogens. This study examines the isolation of Aeromonas and other enteric bacterial pathogens from patients with and without inflammatory bowel disease (IBD). This study also investigates the intestinal epithelial pathogenic mechanisms of Aeromonas veronii . The isolation rates of seven enteric bacterial pathogens from 2,279 patients with IBD and 373,276 non-IBD patients were compared. An A. veronii strain (AS1) isolated from intestinal biopsies of a patient with IBD was used for pathogenic mechanism investigation, and Escherichia coli K12 was used as a bacterial control...

Cervical cancer (CC) is the fourth most common cancer affecting women worldwide. The risk of women immunosuppressed due to AIDS or organ transplantation is well documented, as most cases are caused by persistent human papillomavirus (HPV) infection and immunosuppression can prevent clearing HPV. Although European guidelines advise that inflammatory bowel disease (IBD) women under immunosuppression should be screened for CC as regularly as high-risk patients, quality evidence is lacking in our country. We performed a retrospective case-control (2020-2021) study to analyse the risk factors associated with the appearance of low-grade (LSIL) or high-grade (HSIL) squamous intraepithelial cervical lesions in patients with IBD...

BACKGROUND AND AIMS: Outpatient clinical notes are a rich source of information regarding drug safety. However, data in these notes are currently underutilized for pharmacovigilance due to methodological limitations in text mining. Large language models (LLM) like BERT have shown progress in a range of natural language processing tasks but have not yet been evaluated on adverse event detection. METHODS: We adapted a new clinical LLM, UCSF BERT, to identify serious adverse events (SAEs) occurring after treatment with a non-steroid immunosuppressant for inflammatory bowel disease (IBD)...

Inflammatory bowel disease is a common condition in cats, characterized by recurring gastrointestinal signs with histologic evidence of intestinal inflammation. A 9-month-old neutered male Sphynx cat was presented with a 5-week history of vomiting and hematochezia. Conservative patient management with a therapeutic gastrointestinal formula, antibiotics, and antiemetics resulted in a positive response to treatment, with relapse of signs when the medications were discontinued. A new finding of marked eosinophilia and basophilia was identified 3 months after the initial presentation...

BACKGROUND: The increased prevalence of inflammatory bowel disease (IBD) among patients with obesity and type 2 diabetes suggests a causal link between these diseases, potentially involving the effect of hyperglycemia to disrupt intestinal barrier integrity. AIM: To investigate whether the deleterious impact of diabetes on the intestinal barrier is associated with increased IBD severity in a murine model of colitis in mice with and without diet-induced obesity. METHODS: Mice were fed chow or a high-fat diet and subsequently received streptozotocin to induce diabetic-range hyperglycemia...

BACKGROUND: Pulmonary carcinoids are rare, low-grade malignant tumors characterized by neuroendocrine differentiation and relatively indolent clinical behavior. Most cases present as a slow-growing polypoidal mass in the major bronchi leading to hemoptysis and pulmonary infection due to blockage of the distal bronchi. Carcinoid syndrome is a paraneoplastic syndrome caused by the systemic release of vasoactive substances that presents in 5% of patients with neuroendocrine tumors. Due to such nonspecific presentation, most patients are misdiagnosed or diagnosed late and may receive several courses of antibiotics to treat recurrent pneumonia before the tumor is diagnosed...

BACKGROUND: The causes for immune-mediated inflammatory diseases (IMIDs) are diverse and the incidence trends of IMIDs from specific causes are rarely studied. The study aims to investigate the pattern and trend of IMIDs from 1990 to 2019. METHODS: We collected detailed information on six major causes of IMIDs, including asthma, inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis, psoriasis, and atopic dermatitis, between 1990 and 2019, derived from the Global Burden of Disease study in 2019...

BACKGROUND: For adults with inflammatory bowel disease (IBD), they experience many challenges in dietary decision-making. Thus, this study examined the perspective and experiences of adults with IBD in dietary decision-making. OBJECTIVE: This study aimed to explore the perception and consideration of people with IBD in their daily dietary decisions through monitoring, interpretation and action during the decision-making process. DESIGN: A qualitative study of individuals affected by IBD was conducted through semistructured interviews...

RATIONALE AND OBJECTIVES: To investigate if the combination of multishot diffusion imaging-based multiplexed sensitivity encoding intravoxel incoherent motion (MUSE-IVIM) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is feasible for staging Crohn's disease (CD) activity. MATERIALS AND METHODS: A total of 65 CD patients were enrolled and analyzed in this retrospective study. The simplified endoscopic score for Crohn's disease (SES-CD) and magnetic resonance index of activity (MaRIA) were used as the reference...

In patients with suspected phaeochromocytoma, biochemical screening of urine or blood for excess secretion catecholamines and/or their metabolites is performed. Elevated levels of catecholamines and metanephrines help in establishing the diagnosis of phaeochromocytoma. In two patients with adrenal lesions who were subjected to biochemical testing significantly elevated urinary normetanephrines appeared to establish the diagnosis of phaeochromocytoma. However, on subsequent investigations, this was demonstrated to be a 'false positive' finding...

Glucocorticoids have been widely used in the treatment of ulcerative colitis, but not all patients benefit from this therapy due to hormone resistance. Mir-150-5p has been reported to enhance the efficacy of glucocorticoids, and low serum mir-150-5p expression has been linked to glucocorticoid resistance in ulcerative colitis patients. The aim of this study was to elucidate the mechanisms of mir-150-5p regulation on glucocorticoid resistance. An ulcerative colitis mouse model was used to evaluate changes in ulcerative colitis symptoms, inflammatory factors, and glucocorticoid resistance-related gene expression...

Pyoderma gangrenosum (PG) is a rare, noninfectious inflammatory disease of unknown etiology that affects the skin and mucous membranes. The development of PG after partial small bowel resection is very rare and can initially resemble an infectious complication, although it is an inflammatory disease.This report presents the case of a 55-year-old man who underwent partial small bowel resection for incomplete intestinal obstruction and developed postoperative infection-like manifestations, including redness and swelling of the incision, severe pain, and yellow-green turbid fluid from the drainage tube...

Immunoglobulin A nephropathy (IgAN) is the most common glomerulonephritis. It leads to end-stage kidney disease in about a third of the patients within 10 to 20 years. The pathogenesis of IgAN is incompletely understood. It is believed that a dysregulation of the mucosal immune system leads to undergalactosylation of IgA, followed by formation of IgG autoantibodies against undergalactosylated IgA, circulation of these IgG-IgA immune complexes, deposition of the immune complexes in the mesangium, ultimately resulting in glomerular inflammation...

The use of orally-administered therapeutic proteins for treatment of inflammatory bowel disease (IBD) has been limited due to the harsh gastrointestinal environment and low bioavailability that affects delivery to diseased sites. Here, a nested delivery system, termed Gal-IL10-EVs (C/A) that protects interleukin 10 (IL-10) from degradation in the stomach and enables targeted delivery of IL-10 to inflammatory macrophages infiltrating the colonic lamina propria, is reported. Extracellular vesicles (EVs) carrying IL-10 are designed to be secreted from genetically engineered mammalian cells by a plasmid system, and EVs are subsequently modified with galactose, endowing the targeted IL-10 delivery to inflammatory macrophages...

Background: Inflammatory bowel disease (IBD) is a complex and multifactorial inflammatory condition, comprising Crohn's disease (CD) and ulcerative colitis (UC). While numerous studies have explored the immune response in IBD through transcriptional profiling of the enteric mucosa, the subtle distinctions in the pathogenesis of Crohn's disease and ulcerative colitis remain insufficiently understood. Methods: The intact bowel wall specimens from IBD surgical patients were divided based on their inflammatory status into inflamed Crohn's disease (iCD), inflamed ulcerative colitis (iUC) and non-inflamed (niBD) groups for RNA sequencing...

A severe form of autoimmune-mediated inflammatory bowel disease (IBD) is termed as ulcerative colitis (UC) which ultimately results in significant mucosal damage and ulceration. Herbal remedies may be employed as an alternative for treatment of UC instead of conventional medications such as Sulfasalazine. Promising natural remedies for the treatment of IBD, including colitis, are propolis extract (PP) and thymoquinone (TQ). This study is aimed at assessing the potential of liposomal formulations of TQ and Egyptian PP in combination therapy on improving their therapeutic efficacy against ulcerative colitis in order to maximize the potential of their beneficial clinical effects...
