AI Article Synopsis

  • Trefoil factors (TFF) and mucins, produced by goblet cells, are important for gut barrier function during infections and inflammation, particularly in pediatric inflammatory bowel diseases (IBD) like Crohn's disease (CD) and ulcerative colitis (UC).
  • In biopsies from children, TFF2 mRNA levels were lower in inflamed tissues in CD and UC compared to healthy controls, while non-inflamed tissues showed higher TFF2 levels in CD.
  • The research indicates notable changes in mucin and TFF gene expression in children with IBD, suggesting they could play a role in mucosal healing and may serve as biomarkers for disease progression, warranting further investigation.

Article Abstract

In the intestinal mucosa trefoil factors (TFF) and mucins (Muc) - primarily produced by goblet cells - are thought to play a major role in providing barrier function during infection and inflammation. To investigate their role in pediatric Crohn's disease (CD) and ulcerative colitis (UC) we obtained mucosal biopsies of children with CD, UC and healthy controls and analyzed genetic expression. Levels of TFF2 mRNA were lower in inflamed mucosal samples (terminal ileum (TI) and duodenum) of children with CD, but higher in non-inflamed mucosal samples when compared to healthy controls (p < 0.05). Similarly, TFF2 levels in the TI were significantly lower in inflamed UC tissue. Adjustment for goblet cell density revealed slightly less marked, yet significantly different gene expression in IBD and controls. Furthermore, TI expression of TFF2 and Muc2 was inversely correlated with interleukin-8 expression in CD (p = 0.027). In Summary, our data demonstrate significant changes in Muc and TFF mRNA expression in pediatric patients with IBD suggesting a role in mucosal healing. Further studies are needed to elucidate a potential use as biomarkers for disease progression.

Obesity is associated with changes in the gut microbiota, as well as with increased permeability of the intestinal wall. In 130 non-obese volunteers, 57 patients with metabolically healthy obesity (MHO), and 76 patients with metabolically unhealthy obesity (MUHO), bacterial DNA was isolated from stool samples, and the 16S rRNA gene was sequenced. The metabolic profile of the microbiota predicted by PICRUSt2 (https://huttenhower.

Evaluation of Ocular Parameters in Newly Diagnosed Obsessive-Compulsive Disorder Children With Eye-Rubbing Compulsion.

Clin Pediatr (Phila)

December 2024

Department of Child and Adolescent Psychiatry, Recep Tayyip Erdogan University, Rize Training and Research Hospital, Merkez/Rize, Turkey.

Purpose: To determine the ocular structural changes in obsessive-compulsive disorder (OCD) children with eye-rubbing compulsion.

Methods: Participants recruited at the child and adolescent psychiatry clinic were evaluated for the OCD diagnosis. All patients underwent imaging with Scheimpflug corneal topography (Sirius, CSO, Italy), Tomey EM-4000 specular microscopy (Nagoya, Japan), and Lenstar LS 900 (Haag-Streit AG, Switzerland) optical biometry.

Benign prostatic hyperplasia(BPH) is a common disease in middle-aged and elderly men, with lower urinary tract symptoms as the main manifestation, severely affecting the quality of life of patients. The pathogenesis of BPH is not yet fully understood, and there are still some challenges and limitations in western medicine treatment for BPH. Therefore, finding new and more effective treatment strategies is urgent.

It is imperative to preserve the integrity of the gastrointestinal system in spite of the persistent existence of harmful chemicals and microbial flora in the gut. This is made possible by essential healing initiators called Trefoil factors which helps in mucosal reconstitution and tissue development on the gastrointestinal surface. The trefoil factors are a class of abundant secreted proteins that are essential for epithelial continuity (TFFs).

Infecting humans with controlled doses of small intestinal helminths, such as human hookworm, is proposed as a therapy for the colonic inflammatory disease ulcerative colitis. Strengthening the colonic mucus barrier is a potential mechanism by which small intestinal helminths could treat ulcerative colitis. In this study, we compare C57BL/6 mice infected with the small intestinal helminth and uninfected controls to investigate changes in colonic mucus.
