Diagnostic value of rectal mucosal acetylcholinesterase levels in Hirschsprung's disease
Insights
Measuring acetylcholinesterase (AChE) activity in rectal biopsies aids Hirschsprung
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Biochemistry
Background:
- Hirschsprung's disease is a congenital condition affecting the large intestine.
- Accurate diagnosis is crucial for timely intervention.
- Acetylcholinesterase (AChE) is an enzyme relevant to neuronal function.
Purpose of the Study:
- To evaluate the diagnostic utility of acetylcholinesterase (AChE) activity in rectal biopsies for Hirschsprung's disease.
Main Methods:
- Rectal biopsy specimens were collected from 68 children suspected of Hirschsprung's disease.
- Acetylcholinesterase (AChE) activity was quantified in the biopsy tissues.
- Enzyme activity levels were compared between confirmed Hirschsprung's cases and controls.
Main Results:
- Children with Hirschsprung's disease exhibited significantly higher mean AChE activity (30.5 X 10(-7) units/g tissue) compared to non-Hirschsprung cases (mean 5.0 X 10(-7) units/g tissue).
- The highest AChE activity in the non-Hirschsprung group was 10.9 X 10(-7) units/g tissue.
- Results were not influenced by patient age, sex, biopsy method, or blood presence.
Conclusions:
- Assaying acetylcholinesterase (AChE) activity in rectal biopsies is a simple, rapid, and effective method for diagnosing Hirschsprung's disease.
- This biochemical test offers a valuable diagnostic tool in pediatric surgical and gastroenterological practice.
Abstract:
Acetylcholinesterase (AChE) activity was measured in rectal biopsy specimens obtained from 68 children aged between 2 days and 14 1/2 years in whom Hirschsprung's disease was suspected. The diagnosis was subsequently established in 12; in these, the mean AChE activity was found to be 30.5 X 10(-7) units/g tissue (range 16.9 to 63.0). The 56 non-Hirschsprung cases had a mean of 5.0 X 10(-7) units/g tissue (S.D. 2.2), the highest value in this group being 10.9. The results were unaffected by age, sex, nature of biopsy procedure, or the presence of blood. It is suggested that the assay of AChE activity in rectal biopsy material is a simple and quick procedure that is useful in the diagnosis of Hirschsprung's disease.
