A novel treatment for severe Crohn's disease (CD) using serotonin and dopamine precursors led to sustained remission. This suggests a serotonin-dopamine imbalance may be key in CD pathogenesis.
Area of Science:
- Gastroenterology
- Neurogastroenterology
- Biochemistry
Background:
- Crohn's disease (CD) is a chronic inflammatory bowel disease with limited therapeutic options.
- Current understanding suggests complex etiological factors, including genetic and environmental influences.
Observation:
- A 37-year-old male with a 22-year history of severe, treatment-refractory Crohn's disease was studied.
- The patient underwent a novel treatment protocol involving serotonin and dopamine amino acid precursors.
Findings:
- Symptomatic remission was achieved within 5 days of balancing serotonin and dopamine levels.
- Sustained remission was maintained without conventional Crohn's disease medications.
Implications:
- Elevated serotonin synthesis and tissue levels in Crohn's disease indicate a potential serotonin-dopamine system imbalance.
- This imbalance may lead to serotonin toxicity, suggesting a primary defect in serotonin-dopamine transport, synthesis, and metabolism contributing to Crohn's disease pathogenesis.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
