Atherosclerosis is the main cause for most cardiovascular diseases, and new biomarkers for this condition are always needed. Peptidase M20 domain containing 1 (PM20D1) is associated with both lipid metabolism and obesity. However, no study focuses on the role of PM20D1 in carotid atherosclerosis. The present study aimed to investigate the role of PM20D1 in carotid atherosclerosis patients. The present prospective observational study contained a total of 231 carotid atherosclerosis patients, who went to our department between July 2018 and December 2019. Blood samples and medical characteristics were also obtained from 231 healthy individuals with the same body mass index distribution of carotid atherosclerosis patients. Serum PM20D1 was determined using enzyme-linked immunosorbent assay. Clinical and demographic characteristics of all patients were collected, including age, sex, body mass index and medical history. Levels of C-reactive protein, tumor necrosis factor, homocysteine, as well as total cholesterol, triglyceride, high-density leptin cholesterol and low-density leptin cholesterol were recorded. Statistical analysis was conducted using the SPSS software, with p<0.05 as statistically different. Serum PM20D1 levels were markedly lower in carotid atherosclerosis patients when compared to the healthy control, which were significantly lower in severe carotid atherosclerosis patients and carotid atherosclerosis/stroke patients. Patients with unstable plaques showed markedly lower PM20D1 when compared to patients with stable plaques. No significant difference was found among carotid atherosclerosis patients with different body mass index. Patients with higher PM20D1 levels showed significantly lower expression of C-reactive protein, tumor necrosis factor, homocysteine, triglyceride, total cholesterol and low-density leptin cholesterol. PM20D1 was negatively correlated with C-reactive protein, tumor necrosis factor, homocysteine, total cholesterol and low-density leptin cholesterol in carotid atherosclerosis patients, and could be used as a biomarker for severe carotid atherosclerosis patients or carotid atherosclerosis patients with stroke. Sex, tumor necrosis factor, homocysteine and PM20D1 were risk factors for carotid atherosclerosis. PM20D1 was decreased in carotid atherosclerosis patients and was associated with severity, plaque stability, and levels of C-reactive protein, tumor necrosis factor, homocysteine, triglyceride, total cholesterol and low-density leptin cholesterol in carotid atherosclerosis patients.
