Cytokine and Growth Factor Changes and Correlation With Clinical Outcomes Following Acupuncture for TMD

Deskripsi
Temporomandibular disorder (TMD) is known to be the second most frequent musculoskeletal pain condition following low back pain. According to the NIDCR, TMD affects 5%-12% of the population at an annual cost estimated at 4 billion dollars in the US. Recent studies that have investigated acupuncture as a treatment for musculoskeletal pain have reported various results. Several meta-analyses and systematic reviews of randomized controlled trials suggest that acupuncture treatment improves TMD-related pain. Its mechanism of action in improving TMD pain, however, is largely unclear.
Elevated levels of pro-inflammatory cytokines, e.g., MCP-1 and IL-8 have been found in circulating blood of patients with TMD. Upregulated pro-inflammatory cytokine levels have been correlated with greater sensitivity to pain evoking stimuli. Abnormalities in levels of pro-inflammatory cytokines are often accompanied by alterations in levels of anti-inflammatory cytokines, e.g., IL-1ra, which are associated with reductions in pain and inflammation. The effects of acupuncture on pro- and anti-inflammatory cytokines, growth factors, and clinical pain and function have not been reported in a prospective cohort of TMD patients at multiple time points in the clinical setting. The proposed mechanistic study seeks to ascertain if acupuncture compared to sham acupuncture produces measurable changes in circulating pro- and anti-inflammatory cytokines and growth factors in a manner that is associated with patient self-reports of pain and function over a 4-week treatment period. Cytokine and growth factor levels will be measured in blood and saliva; saliva will be used to measure cytokine levels only.
