Acupuncture improves the symptoms, intestinal microbiota, and inflammation of patients with mild to moderate Crohn's disease: A randomized controlled trial.

Researchers in China studied whether acupuncture could help people with Crohn's disease, a chronic inflammatory bowel condition that causes abdominal pain, diarrhea, and other digestive problems. The study included 66 patients with mild to moderate Crohn's disease whose symptoms weren't adequately controlled by medication alone. Half received real acupuncture with moxibustion (a warming technique) three times per week for 12 weeks, while the other half received sham (fake) acupuncture as a comparison.

The results were encouraging. After 12 weeks, 42% more patients in the real acupuncture group achieved clinical remission compared to the sham group, and 45% more experienced significant symptom improvement. These benefits lasted through the 48-week study period. The acupuncture group also showed lower disease activity scores, reduced inflammation markers in the blood, and better endoscopic findings when doctors examined their intestines. Importantly, patients had fewer disease flare-ups during the follow-up period.

Researchers discovered that acupuncture appeared to work through multiple mechanisms: it increased beneficial anti-inflammatory bacteria in the gut (particularly Faecalibacterium prausnitzii and Roseburia faecis), strengthened the intestinal barrier, and reduced inflammatory signaling molecules in the bloodstream. These findings suggest acupuncture may offer a valuable complementary treatment option for people with Crohn's disease, particularly those who haven't responded adequately to conventional medications.

For patients considering acupuncture for Crohn's disease, it's important to work with a licensed acupuncturist experienced in treating digestive conditions and to maintain communication with your gastroenterologist.

This randomized, sham-controlled trial (n=66) evaluated acupuncture plus moxibustion for mild-to-moderate active Crohn's disease unresponsive to conventional treatment. Patients received three sessions weekly for 12 weeks with 36-week follow-up. The acupuncture group demonstrated significantly higher clinical remission rates versus sham at week 12 (difference: 42.4%, 95% CI: 20.1%-64.0%) and clinical response rates (difference: 45.5%, 95% CI: 24.0%-66.9%), sustained through week 48. Secondary outcomes showed significant reductions in CDAI scores, C-reactive protein, endoscopic severity index, histopathological scores, and recurrence rates. Mechanistic investigations revealed increased operational taxonomic units and relative abundance of anti-inflammatory bacteria (Faecalibacterium prausnitzii, Roseburia faecis), decreased plasma diamine oxidase and lipopolysaccharide (suggesting enhanced intestinal barrier integrity), and downregulation of Th1/Th17-related cytokines. Clinical takeaway: Acupuncture with moxibustion demonstrates sustained efficacy for inducing and maintaining remission in treatment-refractory CD through microbiome modulation, intestinal barrier enhancement, and immune regulation.
