BACKGROUND: Inflammatory bowel disease (IBD) is a chronic disease of unknown etiology in which genetic factors contribute to development of disease. Single nucleotide polymorphisms (SNPs) in multidrug resistance 1 (MDR1) gene encoding transporter P-glycoprotein have been associated with IBD, but their role in disease susceptibility remains unclear. Therefore, the aim of this study was to investigate the association of three MDR1 polymorphisms, C1236T (rs1128503), G2677T/A (rs2032582) and C3435T (rs1045642), with Serbian IBD patients...

Studies of the human intestinal microbiome in patients with inflammatory bowel disease (IBD) consistently show that there are differences (an abnormal or unbalanced microbiome, "dysbiosis") when compared to healthy subjects. We sought to describe changes in the microbiome in individual patients over time, and determine the clinical factors that are associated with significant alteration. Forty-two mucosal biopsies were collected from 20 patients that were spaced an average of 2.4 years apart. These were analysed using bacterial 16S rRNA gene high-throughput sequencing methods...

Triggering receptor expressed on myeloid cells 1 (TREM-1)-expressing intestinal macrophages are significantly increased in the colons of patients with inflammatory bowel disease (IBD). We focused here on the effects of guggulsterone on macrophage modulation in colitis as a potential therapeutic molecule in human IBD and explore the underlying mechanisms. Gene expression in macrophages was examined and wound healing assay using HT-29 cells was performed. Colitis in wild type and IL-10-, TLR4-, and MyD88-deficient mice was induced via the administration of 2,4,6-trinitrobenzene sulfonic acid (TNBS) into the colon...

OBJECTIVES: Cytomegalovirus (CMV) disease is more common in immunocompromised patients but may occur in people with normal immune function. In addition, CMV enterocolitis can aggravate inflammatory bowel diseases (IBD), but there was little knowledge of differences in clinical and endoscopic features of CMV enterocolitis between patients with IBD and without IBD. The aim of this study was to determine the difference in clinical implication in CMV enterocolitis between the IBD patients and non-IBD patients...

BACKGROUND: Diagnosis of pediatric inflammatory bowel diseases (IBD) remains challenging. We aimed at the value of immunohistochemical assessment of CD30+ lymphocytes in the intestinal mucosa in differential diagnosis between pediatric Crohn's disease (CD) and ulcerative colitis (UC) and its utility as a predictor of future differentiation in patients with IBD unclassified (IBDU). METHODS: Seventy-four treatment naive pediatric patients with IBD (33 CD, 30 UC and 11 IBDU) were enrolled into the study...

Infectious bursal disease virus (IBDV) belongs to the Birnaviridae family and is the etiological agent of a highly contagious and immunosuppressive disease (IBD) that affects domestic chickens ( Gallus gallus ). IBD or Gumboro disease leads to high morbidity and mortality of infected animals, and is responsible for major economic losses to the poultry industry world-wide. IBD is characterized by a massive loss of IgM-bearing B lymphocytes and the destruction of the bursa of Fabricius. The molecular bases of the IBDV pathogenicity are still poorly understood, nonetheless, an exacerbated cytokine immune response and B cell depletion due to apoptosis are considered main factors contributing to the severity of the disease...

Birnaviruses are unconventional members of the double-stranded RNA (dsRNA) viruses group that are characterized by the lack of a transcriptionally active inner core. Instead, the birnaviral particles organize their genome in ribonucleoprotein complexes (RNPs) composed by dsRNA segments, the dsRNA-binding VP3 protein, and the viral encoded RNA-dependent RNA-polymerase (RdRp). This and other structural features suggests that birnaviruses may follow a completely different replication program from that followed by members of the Reoviridae family, supporting the hypothesis that birnaviruses are the evolutionary link between single-stranded positive RNA (+ssRNA) and dsRNA viruses...

We assessed the subsequent risk of cholelithiasis development in patients with inflammatory bowel diseases (IBDs) such as Crohn's disease (CD) or ulcerative colitis (UC). We identified 8186 patients who aged ≥20 years and were diagnosed with IBD between 2000 and 2010 as the study cohort. A total of 8186 patients without IBD were selected by frequency-matching according to age, sex, comorbidities, and the index date of diagnosis, and they were identified as the control cohort. To measure the incidence of cholelithiasis, all patients were followed up until the end of 2011...

OBJECTIVE: Currently, a biosimilar of Remicade is available (CT-P13). Switching patients from Remicade to a biosimilar is still under debate, especially for patients with inflammatory bowel disease (IBD). In a retrospective study, we investigated the feasibility and safety of switching patients with IBD from Remicade to a biosimilar infliximab. PATIENTS AND METHODS: At two large general hospitals in The Netherlands, adult patients with a diagnosis of Crohn's disease or ulcerative colitis being treated with Remicade were asked to switch to the biosimilar infliximab (CT-P13)...

PURPOSE OF REVIEW: The intestinal microbiome is thought to play a role in the pathogenesis of inflammatory bowel disease (IBD). There are many shared clinical manifestations between IBD and spondyloarthritis (SpA), of which the most common are peripheral arthritis and uveitis. Clinical overlap along with similar genetics between these diseases suggests a possible shared pathogenetic mechanism, which might center on the intestinal microbiota. In this review, we discuss the available evidence that SpA is a microbiome-driven disease and indicate how SpA-associated uveitis could be tied to gut dysbiosis...

Background and aim: Nationwide epidemiological data on ulcerative colitis (UC) in Spain are lacking. The primary objective was to assess the epidemiology of UC at hospital gastroenterology units and the use of hospital resources (characteristics and facilities) for the management of UC in Spain. Methods: A retrospective, multicenter, epidemiological, cross-sectional study (EPICURE study) analyzed data from hospital registries and records from UC patients admitted and treated in 2011 at a representative selection of Spanish sites...

Interactions among the gut microbiome, dysregulated immune responses, and genetic factors contribute to the pathogenesis of inflammatory bowel disease (IBD). Nlrx1 -/- mice have exacerbated disease severity, colonic lesions, and increased inflammatory markers. Global transcriptomic analyses demonstrate enhanced mucosal antimicrobial defense response, chemokine and cytokine expression, and epithelial cell metabolism in colitic Nlrx1 -/- mice compared to wild-type (WT) mice. Cell-specificity studies using cre-lox mice demonstrate that the loss of NLRX1 in intestinal epithelial cells (IEC) recapitulate the increased sensitivity to DSS colitis observed in whole body Nlrx1 -/- mice...

Corticosteroids and antibodies to tumor necrosis factor (anti-TNF) are mainstays of treatment of acutely active IBD and while anti-TNF therapy is indicated for maintenance therapy, chronic corticosteroid therapy is associated with known significant risks. Nonetheless, chronic or recurrent corticosteroid treatment in IBD is common. In this edition of the journal Lewis et al. use Medicaid and Medicare databases to contrast adverse outcomes in persons with IBD and either corticosteroid or anti-TNF use. Compared to high dose corticosteroid use, anti TNF therapy is associated with less risk for death in Crohn's disease but no statistical difference in death outcomes in ulcerative colitis...

BACKGROUND: The increasing incidence of inflammatory bowel disease (IBD) in western countries has led to the hypothesis that obesity-related inflammation could play a role in the etiology of IBD. However, this hypothesis lacks confirmation in studies of individuals prior to the typical onset of IBD in young adulthood. METHODS: In a cohort of 316,799 individuals from the Copenhagen School Health Records Register (CSHRR), we examined whether BMI at ages 7 through 13 years was associated with later IBD...

PURPOSE: The timing of J-pouch surgery following colectomy for children with very early-onset colitis is controversial, with some advocating early reconstruction and others delaying reconstruction because of fear that the colitis may be owing to Crohn's disease (CD). We sought to determine the long-term incidence of CD in this population and whether there may be clinical features that predict the risk of CD. METHODS: Children with noninfectious colitis diagnosed prior to age 10, who underwent subtotal colectomy and ileostomy from 2000 to 2015, were reviewed...

This paper engages critically with the global assemblage framing sickle cell and thalassaemia disorders as a 'global health crisis'; and the promise of genomics, largely DNA-based carrier/pre-conceptual screening, prenatal diagnosis with a view to terminations, deployed in framing a solution to these historically racialised spectrum of diseases as essentially preventable. Sickle cell and thalassaemia are recessively inherited, potentially life-threatening haemoglobin disorders with significant variation of severity, often needing life-long treatment...

Inflammatory bowel disease (IBD) is a collection of inflammatory conditions of colon and small intestine which affect millions of individuals worldwide and the prevalence amount is on the rise. The organ failure as well as loss of tissue function is because of the inflammatory reaction which is the major contributor of tissue healing leading to lifelong debilitation. To stop the tough consequences of inflammation every patient pursues alternative therapy to relieve symptoms. Green tea polyphenols (GTPs) play significant roles in down regulating signaling pathways because GTPs exert effective antioxidant properties and regulate Toll-like receptor 4 (TLR4) expression via certain receptor, inhibited endotoxin-mediated tumor necrosis factor alpha (TNF-α) production by blocking transcription nuclear factor-kappa B (NF-kB) activation and upstream of mediated I kappa B kinase complex pathway activities, as well as intrusion with the flow of cytokines and synthesis of cyclooxygenase-2 (COX-2)...
