crohn’s disease

Uma Keyal, Yeqiang Liu, Anil Kumar Bhatta
Inflammatory bowel disease (IBD) is a chronic relapsing disease of the gastrointestinal tract with unknown etiology and pathogenesis. It includes Crohn's disease (CD) and ulcerative colitis (UC). Approximately one-third of the patients with IBD are seen to develop extraintestinal manifestations, among which cutaneous manifestations are the most common and should be managed in close collaboration with a dermatologist. Depending upon the nature of the association, skin conditions associated with IBD can be listed under 4 categories: specific, reactive, secondary to malnutrition or malabsorption, and secondary to drug therapy...

OBJECTIVES: While infliximab pharmacokinetics are associated with therapy outcome in adult IBD population, limited data is available in pediatric patients. We aimed to define the relationship between Infliximab trough and antibodies' levels (IFX-TL, ATI) and clinical, biomarker remission. METHODS: IFX-TL and ATI were routinely obtained between 2011-2017. Associations with clinical and inflammatory (C-reactive protein, CRP) end-points were studied throughout the first year of infliximab therapy...

Background: The Montreal classification defines L4 Crohn's disease (CD) as any disease location proximal to the terminal ileum, which anatomically includes L4-esophagogastroduodenal (EGD), L4-jejunal, and L4-proximal ileal involvement. L4-jejunal disease was established to be associated with poor prognosis. However, the outcome of patients with L4-proximal ileal disease or L4-EGD remains to be clarified. Our study aimed to investigate whether the outcome differs among CD patients with L4-EGD, L4-jejunal, and L4-proximal ileal disease...

Inflammatory bowel diseases (IBDs) are chronic, idiopathic, relapsing disorders of unclear etiology affecting millions of people worldwide. Aberrant interactions between the human microbiota and immune system in genetically susceptible populations underlie IBD pathogenesis. Despite extensive studies examining the involvement of the gut microbiota in IBD using culture-independent techniques, information is lacking regarding other human microbiome components relevant to IBD. Since accumulated knowledge has underscored the role of the oral microbiota in various systemic diseases, we hypothesized that dissonant oral microbial structure, composition, and function, and different community ecotypes are associated with IBD; and we explored potentially available oral indicators for predicting diseases...

Recent studies suggested that excessive Th1/17 cells concomitant with regulatory T cell deficiency might play important roles in Crohn's disease. Anti-CD52 mAb, which aims on CD52 antigen on mature immunocytes, has both T cell depletion and immunosuppressive activities. In this study, we evaluated the therapeutic effects and possible mechanisms of anti-CD52 treatment on interleukin-10 deficient mouse. Anti-mouse CD52 mAb was administered to C3H.IL-10-/- mice intraperitoneally 20μg per week for 2 weeks. The disease activity index, body weight, the histological grading of colitis, and levels of TNF-α, IFN-γ, IL-17 and IL-6 in colon were quantified after treatment...

Proteus species, members of the Enterobacteriaceae family, are usually considered commensals in the gut and are most commonly recognized clinically as a cause of urinary tract infections. However, the recent identification of Proteus spp. as potential pathogens in Crohn's disease recurrence after intestinal resection serves as a stimulus to examine their potential role as gut pathogens. Proteus species possess many virulence factors potentially relevant to gastrointestinal pathogenicity, including motility; adherence; the production of urease, hemolysins, and IgA proteases; and the ability to acquire antibiotic resistance...

The development of colorectal cancer in long-standing Crohn's disease (CD) patients has become a major complication. Therapeutic guidelines for CD-associated cancer (CDAC) have already been established in Western countries; however, specific guidelines are not currently available in Japan. Surveillance of the residual intestine for cancer screening is important for long-standing CD patients. The present case report describes the occurrence of rectal carcinoma in a patient with a 25-year history of CD. A 37-year-old male with a 17-year history of CD underwent semi-emergent subtotal colectomy and ileostomy for bowel obstruction secondary to the transverse colon stenosis, and multiple severe stenosis and inflammation...

Mesenchymal stem cells (MSCs; also referred to as mesenchymal stromal cells) have attracted much attention for their ability to regulate inflammatory processes. Their therapeutic potential is currently being investigated in various degenerative and inflammatory disorders such as Crohn's disease, graft-versus-host disease, diabetic nephropathy and organ fibrosis. The mechanisms by which MSCs exert their therapeutic effects are multifaceted, but in general, these cells are thought to enable damaged tissues to form a balanced inflammatory and regenerative microenvironment in the presence of vigorous inflammation...

OBJECTIVE: Inflammatory bowel disease (IBD) patients with Clostridium difficile co-infection (CDCI) have an increased risk of morbidity and mortality. We aim to evaluate the impact of CDCI on in-hospital outcomes among adults with IBD hospitalized in the USA. PATIENTS AND METHODS: Using the 2007-2013 Nationwide Inpatient Sample, hospitalizations among US adults with Crohn's disease (CD), ulcerative colitis (UC) and CDCI were identified using ICD-9 coding. Hospital charges, hospital length of stay (LOS), and in-hospital mortality was stratified by CD and UC and compared using χ-testing and Student's t-test...

Background: In Crohn's disease (CD) a small bowel study-in addition to colonoscopy-is considered necessary for diagnosis/staging. In this study we re-examined the role of capsule endoscopy (CE), colonoscopy, imaging tests [magnetic resonance enterography/computed tomographic enterography (MRE/CTE)], and inflammatory markers [fecal lactoferrin and C-reactive protein (FL/CRP)] in CD patients who had undergone intestinal resection and in those who never had surgery. Methods: In this retrospective study 43 consecutive patients underwent CE because of staging/symptoms unexplained by colonoscopy/imaging...

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) typically clinically manifest with symptoms like chronic diarrhea, cramps, abdominal pain, and rectal bleeding. However, symptoms of abnormal anorectal function seem to be of equal importance, regardless of the presence or absence of perianal disease. OBJECTIVES: The aim of this study was to assess stool patterns and the prevalence of symptoms of disordered anorectal function, particularly urgency and fecal incontinence, and their severity in patients with inflammatory bowel diseases (IBDs)...

Human adult stem cells, including umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs), have recently been considered a promising alternative treatment for inflammatory bowel disease (IBD) due to their unique immunomodulatory properties and ability to promote tissue regeneration. However, despite many years of research and pre-clinical studies, results from clinical trials using these cells have been diverse and conflicting. This discrepancy is caused by several factors, such as poor engraftment, low survival rate, and donor-dependent variation of the cells...
