Abnormal lactic dehydrogenase isoenzyme patterns in ulcerative colitis with precancerous change
Gut
|January 1, 1971
Summary
Lactic dehydrogenase isoenzyme analysis in rectal biopsies revealed significant changes in patients with ulcerative colitis and precancerous conditions. This enzyme pattern may aid in detecting precancer in ulcerative colitis.
Area of Science:
- Biochemistry
- Gastroenterology
- Oncology
Background:
- Ulcerative colitis is a chronic inflammatory bowel disease.
- Precancerous changes in ulcerative colitis increase colorectal cancer risk.
- Early detection of precancer is crucial for patient outcomes.
Purpose of the Study:
- To investigate the isoenzyme pattern of lactic dehydrogenase in rectal biopsies.
- To determine if lactic dehydrogenase isoenzyme patterns can help identify precancer in ulcerative colitis.
Main Methods:
- Rectal biopsies were obtained from six patients with ulcerative colitis.
- Histological precancerous changes were independently recognized.
- Isoenzyme patterns of lactic dehydrogenase were measured.
Main Results:
- A significant increase in the ratio of lactic dehydrogenase isoenzymes IV + V to I + II was observed.
- This specific isoenzyme shift was noted in patients with precancerous changes.
Conclusions:
- Lactic dehydrogenase isoenzyme measurement shows potential as a biomarker.
- It may complement traditional histology for precancer detection in ulcerative colitis.
- Further research is warranted to validate these findings.

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

79
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows...

57
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal...

69
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The...
