Acupuncture therapy in autoimmune diseases: A narrative review.

Researchers reviewed over two decades of studies examining how acupuncture affects autoimmune diseases—conditions where the immune system mistakenly attacks the body's own tissues. The review included laboratory studies on animals and clinical trials involving human patients with conditions like rheumatoid arthritis, multiple sclerosis, psoriasis, inflammatory bowel disease, fibromyalgia, and Sjögren's syndrome. The scientists found that acupuncture appears to work through several mechanisms in the body. In laboratory studies, acupuncture reduced inflammation by decreasing harmful inflammatory chemicals while increasing protective ones, improved the function of regulatory immune cells, and activated the body's natural anti-inflammatory pathways involving the vagus nerve. For pain relief, acupuncture affected both the area being treated and the central nervous system. When looking at human clinical trials, the strongest evidence supported using acupuncture for rheumatoid arthritis, fibromyalgia, Crohn's disease, and Sjögren's syndrome. There was also some evidence suggesting acupuncture might help with symptoms of multiple sclerosis, myasthenia gravis, psoriasis, and ankylosing spondylitis, though more research is needed. For patients with autoimmune conditions, this review suggests acupuncture may offer benefits both by reducing inflammation at a cellular level and by providing pain relief. The treatment appears to be most helpful when used alongside conventional medical care rather than as a replacement. If you're considering acupuncture for an autoimmune condition, seek a licensed acupuncturist with experience treating autoimmune disorders.

This narrative review analyzed randomized controlled trials, systematic reviews, and meta-analyses published between 2000-2023 examining acupuncture's effects on autoimmune diseases. Preclinical models demonstrated that acupuncture downregulated pro-inflammatory cytokine expression, upregulated IL-10, enhanced Treg cell differentiation, and modulated macrophage polarization in rheumatoid arthritis and ulcerative colitis models. Mechanistic studies identified vagal-adrenal and cholinergic anti-inflammatory pathways as key mediators of acupuncture's anti-inflammatory effects, while analgesic mechanisms involved both peripheral and central anti-nociceptive pathways. Clinical evidence from RCTs most strongly supports acupuncture use in rheumatoid arthritis, fibromyalgia, Crohn's disease, and Sjögren's syndrome. Preliminary evidence suggests potential symptomatic benefits for multiple sclerosis, myasthenia gravis, psoriasis, and ankylosing spondylitis. Clinical takeaway: Acupuncture demonstrates immunomodulatory effects through multiple pathways and has Level I evidence supporting its use as adjunctive therapy in select autoimmune conditions, particularly for pain management and inflammation reduction.
