Decreased Microvilli Length, and Associated Gene Expression Changes, in Patients With Crohn’s Disease

In an analysis of intestinal tissues from patients with Crohn’s disease (CD), researchers identified specific changes in gene expression patterns that associate with histologic changes, such as differences in microvilli length. Decreased microvilli length, via decreased expression of the microvilli gene set, might contribute to epithelial malfunction and the chronic

Is it Safe or Effective to Combine Therapies for Inflammatory Bowel Diseases?

Little is known about the efficacy and safety of combination targeted therapy for inflammatory bowel diseases (IBD), despite their use in treatment of other immune-mediated disorders. In a review article in the September issue of Clinical Gastroenterology and Hepatology, Robert P. Hirten et al discuss findings from studies of biologic

Does Mucosal Healing Mean Transmural Healing in Children With Crohn’s Disease?

 One-third of children with Crohn’s disease have healing in only the mucosa or the bowel wall (not both), researchers report in the July issue of Clinical Gastroenterology and Hepatology. Levels of fecal calprotectin below 300 μg/identify children with mucosal healing. In patients with CD, mucosal healing is associated with reduced risk of relapse,

  • What Happens When Patients With Crohn’s Disease in Remission Stop Taking Infliximab?

What Happens When Patients With Crohn’s Disease in Remission Stop Taking Infliximab?

When patients with Crohn’s disease in sustained remission stopped taking infliximab for a median 7 years, almost one fifth did not require retreatment or have a major complication, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Fewer than one fifth of patients required surgery or developed a complex perianal fistula. Increasing numbers of patients

Does Immunomodulator Therapy for IBD During Pregnancy Affect Newborn Response to Vaccines?

Rates of adequate serologic response to Haemophilus influenzae B (HiB) and tetanus vaccines are similar among infants born to women with inflammatory bowel diseases (IBD) treated with immunomodulator or biologic agents compared to women who did not receive these immunosuppressive drugs during pregnancy, researchers report in the January issue of Clinical Gastroenterology

  • Does Asthma Increase Risk for Inflammatory Bowel Diseases?

Does Asthma Increase Risk for Inflammatory Bowel Diseases?

A population-based case–control study published in the September issue of Clinical Gastroenterology and Hepatology associates asthma with later development of Crohn’s disease (CD) and with ulcerative colitis (UC). Although the etiology of asthma and inflammatory bowel diseases (IBD) are not well understood, they both involve complex interactions among genetic and environmental factors and the

  • Is Endoscopic Balloon Dilation Better Than Surgery for Patients With Crohn’s Disease-related Strictures?

Is Endoscopic Balloon Dilation Better Than Surgery for Patients With Crohn’s Disease-related Strictures?

In patients with Crohn’s disease (CD), surgical treatment of ileocolonic anastomosis strictures reduces risk of further surgery compared with endoscopic balloon dilation (EBD), researchers report in the August issue of Clinical Gastroenterology and Hepatology. However, endoscopic balloon dilation (EBD) delays time until need for a second surgery; EBD should be therefore attempted first

  • How Could the Intestinal Microbiota Contribute to Celiac Disease?

How Could the Intestinal Microbiota Contribute to Celiac Disease?

Bacteria in the small intestine metabolize gluten differently, to increase or decrease its immunogenicity, researchers report in the October issue of Gastroenterology. This interaction between microbes and gluten could help determine the risk for autoimmune enteropathy in genetically susceptible individuals and underlie the reported association between dysbiosis and celiac disease.

  • Is Dietary Fiber OK for Patients With Crohn’s Disease or Ulcerative Colitis?

Is Dietary Fiber OK for Patients With Crohn’s Disease or Ulcerative Colitis?

Intake of dietary fiber reduces risk of disease flares in patients with Crohn’s disease, but not ulcerative colitis, researchers report in the August issue of Clinical Gastroenterology and Hepatology. Recommendations to limit dietary fiber should therefore be re-evaluated. Inflammatory bowel diseases (IBD) have been associated with an abnormal mucosal immune response to

  • Can Microbial Dysbiosis Cause Colonic Inflammation?

Can Microbial Dysbiosis Cause Colonic Inflammation?

Dysbiosis contributes to the pathogenesis of inflammatory bowel diseases (IBD) by altering colonic expression of genes that regulate inflammation and the immune response, researchers report in the July issue of Cellular and Molecular Gastroenterology and Hepatology. An altered intestinal microbiota composition has been associated with IBD. However, it is not
