Association of serum resistin with blood stasis syndrome in traditional Korean medicine for metabolic diseases: A cross-sectional multicenter observational study.

Background: Blood stasis syndrome (BSS) is considered as the cause of several chronic disease including metabolic diseases in traditional East Asian medicine. In this study, we investigated the levels of serum resistin and other proteins related to metabolic syndrome (MS) and several other diseases categories to identify the association with BSS.

Methods: This was a cross-sectional, multicenter study of patients recruited from seven traditional Korean Medicine (TKM) hospitals. To identify whether there was an association with BSS in specific disease conditions, including MS, serum protein levels were evaluated using the multiplex method.

Results: A total of 885 patients (419 patients with BSS, 376 patients without BSS, and 90 healthy controls) participated in the study, and 139 patients had MS. The resistin and insulin levels were significantly higher in patients with BSS than in patients without BSS and normal subjects ( = 0.002 and  = 0.046, respectively). Patients with BSS who had MS exhibited significantly higher resistin levels than those in patients without BSS and normal subjects ( = 0.049). In addition, the levels of serum resistin were significantly correlated with symptoms of the BSS, especially dark red gums, dark facial complexion, and nocturnal pain.

Conclusions: Despite several limitations, these results demonstrated that resistin levels are potentially associated with the pathogenesis of BSS in MS.
