ObjectiveTo explore the distribution law of traditional Chinese medicine (TCM) syndrome types in patients with psoriasis vulgaris complicated by metabolic disorders based on the same pathogenic factors as blood-heat and blood-stasis in the pathogenesis of psoriasis and metabolic disorders and to further analyze the correlation between adiponectin and the distribution law.MethodsFrom 1 January 2018 to 31 December 2019, patients diagnosed with psoriasis in the inpatient or outpatient department of Dermatology Ward of Shanghai Yueyang Hospital and normal participants who underwent physical examination in the physical examination center over the same period were retrospectively reviewed. Demographic data, medical history, metabolic disorder indices, and TCM syndrome indices of psoriasis patients and healthy volunteers were evaluated.ResultsWe included 307 patients with psoriasis and 613 healthy controls. On analyzing past medical history, the proportion of overweight and obesity and the comorbidity of diabetes in the psoriasis group (53.42 and 14.66%) were significantly higher than in the control group (43.88 and 7.67%, respectively; p < .05). The abnormal rates of triglyceride (34.20%), high-density lipoprotein cholesterol (50.49%), and HbA1c (18.57%) levels in the psoriasis group were higher than those in the normal control group (26.75, 17.13, and 12.56%, respectively). Overall, the incidence of metabolic disorders in psoriasis patients (267/307, 86.97%) was higher than that in the normal controls (484/613, 78.96%). Among the different syndrome types, the blood-stasis group had significantly higher rates of hypertension, diabetes, and abnormal glycosylated hemoglobin (46.07, 19.10, and 24.72%, respectively) than those of the control group (27.57, 7.67, and 12.56%; p < .05). Patients with blood stasis syndrome had the highest metabolic disorder comorbidity rate (93.26%) and lowest adiponectin level (p < .05).ConclusionsTCM syndrome differentiation of psoriasis, especially the diagnosis of blood-stasis syndrome, prompts the early screening of patients with metabolic comorbidities. For patients with psoriasis with metabolic disorder, TCM for promoting blood circulation and removing blood stasis can be compatibly applied without contraindications.Trial RegistrationThe trial was registered at ClinicalTrials.gov (Trial ID: NCT03942185).
