late on set bowel inflammatory disease

MicroRNAs (miRNAs) are a group of non-coding RNAs that play a critical role in regulating epigenetic mechanisms in inflammation-related diseases. Inflammatory bowel diseases (IBDs), which primarily include ulcerative colitis (UC) and Crohn's disease (CD), are characterized by chronic recurrent inflammation of intestinal tissues. Due to the multifactorial etiology of these diseases, the development of innovative treatment strategies that can effectively maintain remission and alleviate disease symptoms is a major challenge...

BACKGROUND Postoperative ileus (POI) remains the most common complication after colectomy for inflammatory bowel disease (IBD). Delayed POI (DPOI) can develop late (>14 days) after colectomy in clinical settings, with unknown etiology. The aim of this study was to address a novel entity of POI after colectomy for ulcerative colitis (UC). MATERIAL AND METHODS The data of 263 UC patients who underwent colectomy from Jan 1, 2013 to May 31, 2021 were collected. DPOI was defined as POI occurring on or after postoperative day (POD) 14 with apparent resolution from obligatory POI...

BACKGROUND: Amyloidosis is a rare disease characterized by extracellular deposition of misfolded protein aggregated into insoluble fibrils. Gastrointestinal involvement in systemic amyloidosis is common, but is often subclinical or presents as vague and nonspecific symptoms. It is rare for gastrointestinal symptoms to be the main presenting symptom in patients with systemic amyloidosis, causing it to be undiagnosed until late-stage disease. CASE SUMMARY: A 53 year-old man with diarrhea, hematochezia, and weight loss presented to a community hospital...

Crohn's Disease (CD) refers to a chronic transmural bowel inflammation affecting a range between 5 and 15 per 100,000 person-years worldwide 1. In patients with stricturing CD, the transmural pattern of inflammation may trigger the development of sinus tracts able to connect to other tissues, leading to the formation of fistulas or abscesses 2. Intra-psoas abscesses are rare, affecting between 0.4-4.3% of patients with CD 3. We present the case of a 36-year-old male with no past medical history except for a two-week worsening lumbosciatalgia not responding to standard nonsteroidal anti-inflammatory drugs, who complained sudden abdominal pain, with right lower abdominal stiffness combined to a severe edema and erythema of the right lower limb, extended from the gluteus down to the knee, involving the anteromedial and posteromedial areas of his thigh...

BACKGROUND: Crohn's disease is one of the two categories of inflammatory bowel diseases that affect the gastrointestinal tract. The heritability estimate has been reported to be 0.75. Several genes linked to Crohn's disease risk have been identified using a plethora of strategies such as linkage-based studies, candidate gene association studies, and lately through genome-wide association studies (GWAS). Nevertheless, to our knowledge, a compendium of all the genes that have been associated with CD is lacking...

With dermatologic side effects being fairly prevalent following vaccination against COVID-19, and the multitude of studies aiming to report and analyze these adverse events, the need for an extensive investigation on previous studies seemed urgent, in order to provide a thorough body of information about these post-COVID-19 immunization mucocutaneous reactions. To achieve this goal, a comprehensive electronic search was performed through the international databases including Medline (PubMed), Scopus, Cochrane, Web of science, and Google scholar on July 12, 2021, and all articles regarding mucocutaneous manifestations and considerations after COVID-19 vaccine administration were retrieved using the following keywords: COVID-19 vaccine, dermatology considerations and mucocutaneous manifestations...

PURPOSE OF REVIEW: Despite advances in medical and surgical therapy in inflammatory bowel disease (IBD) management, intestinal stomas can be needed in a significant proportion of patients. The impact of stomas in patients' lives is significant, and the topic is still challenging for different specialties involved in IBD care. RECENT FINDINGS: Indications for intestinal ostomies in IBD can occur in elective (malnutrition, anemia, or previous steroids) or emergency (perforation, abdominal abscess, obstruction) settings...

Mesenchymal stem cells (MSCs) have been spotlighted in the field of cell therapies as a promising tool for the treatment of intractable inflammatory diseases. However, their therapeutic potency still shows a gap between preclinical and clinical settings, and distinctive characteristics of specific tissue-derived MSCs and definitive ways to maximize their beneficial functions have not been fully elucidated yet. We previously identified the unique MSCs population from human palatine tonsil (TMSCs) and revealed their superior properties in proliferation and ROS regulation...

Perfluoroalkyl substances (PFAS) can act as surfactants and have been suggested to be capable of affecting gut mucosa integrity, a possible factor in the pathogenesis of inflammatory bowel disease (IBD). So far, only PFOA has been shown to have a positive association with ulcerative colitis. The present study aimed to investigate the association of PFAS and clinically diagnosed IBD in the Ronneby cohort, a population with high PFAS exposure (especially high PFOS and PFHxS) from Aqueous Film-Forming Foam through drinking water, using registry data...

BACKGROUND: To evaluate whether changes in expression of CD39 by regulatory T lymphocytes (Treg) impact treatment response in inflammatory bowel disease. To then define the biological role of expression of CD39 on Treg in an animal model of colitis. METHODS: A prospective study of consecutive patients commencing anti-tumor necrosis factor therapy with infliximab (IFX) or adalimumab (ADA), who were then followed for 12 months. Treatment responses were defined both symptomatically and by endoscopy showing mucosal healing...

Although several studies have investigated the essential roles of inflammation in tumor progression, not many have systematically analyzed gene expression patterns across diverse cancers in the context of inflammation. In this study, in order to better understand the inflammatory scenario, we initially constructed the inflammatory timeline (IT) based on two gene expression profiles during inflammatory progression (inflammatory bowel disease and Helicobacter pylori infection). Then, we separately identified the differentially expressed genes (DEGs) from 25 cancer-related microarray data...

In recent years, genome wide association studies have revolutionized the understanding of the genetic architecture of complex disease, particularly in the context of disorders that present in old age, such as type 2 diabetes and cardiovascular disease. This new era is made all the more compelling by the fact that, through extensive validation efforts, there is now very strong consensus among human geneticists on what the key loci are that contribute to the pathogenesis of these traits. However, as these variants have been almost exclusively uncovered in an adult setting, there is the question of when these genetic variants start exerting their effects; indeed many may start setting up an individual's predisposition to a disease of old age very early on in life...

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with uncertain etiopathogenesis. CD can involve any site of gastrointestinal tract from mouth to anus and is associated with serious complications such as bowel stricture, perforation, abscess, and fistula formation. The incidence and prevalence rates of CD in Korea are still low compared with those of Western countries, but are rapidly increasing during the past decades. The diagnosis of CD is a challenging issue in some clinical situations and it is often difficult to differentiate CD from intestinal tuberculosis or Behçet's enterocolitis which are more prevalent in Korea than in Western countries...

"Pouchitis" is a term for nonspecific mucosal inflammation of the pouch after total proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis. Pouchitis is the most frequent complication of the pelvic pouch at the late stage. To improve the accuracy of the pouchitis diagnosis, sets of clinical symptoms and endoscopic findings (with or without histology of biopsy samples) have previously been evaluated. Endoscopic findings are central to the diagnosis, and a universal consensus of various endoscopic findings must be the initial step toward an objective diagnosis of pouchitis...

BACKGROUND/PURPOSE: Intestinal lesions observed in gastroschisis (Gx) are accompanied by neonatal gastrointestinal dysfunction. This study examines the effects of transplacental dexamethasone on the eviscerated intestine of fetal rats with Gx. METHODS: Gx was created surgically in rat fetuses on gestational day 18, and the dams were treated either with 0.4 mg/kg intraperitoneal dexamethasone or with vehicle only on days 19 and 20. The intestine recovered on day 21 were processed for total DNA and protein...

Inflammatory disorders such as autoimmune diseases and graft rejection are mediated by activated leukocytes, particularly T lymphocytes, which penetrate the inflamed tissue and perpetuate or amplify the immune reaction. In an unstimulated state, leukocytes do not readily adhere to the vascular endothelium. However, inflammatory signals induce the expression of proteins on the endothelial cell surface that promote the adhesion and extravasation of activated immune cells from the circulation into the underlying tissues...

BACKGROUND AND PURPOSE: To assess the correlation between different general and organ specific quality of life and morbidity scoring methods in a cohort of men treated with radical radiotherapy for prostate cancer. MATERIALS AND METHODS: Men who had been treated with radical radiotherapy (50 Gy in 16 fractions over 21 days) for localized prostate cancer more than 3 years previously and who had no evidence of recurrent disease were invited to take part in the study...
