- The major purpose of this study was to assess the association between the potential long-term effects of previous schistosome infection and atherogenic dyslipidemia. Among 1597 men aged ⩾45years who received health examinations and lived in previous schistosomiasis-endemic regions of China, 465 patients with previous schistosome infection were selected as study subjects, and 1132 subjects formed the control group. The risk factors for cardiovascular disease were measured and compared between the previous schistosome infection and control groups. The Atherogenic Index of Plasma, triglycerides, waist circumference and body mass index were significantly lower in the previous schistosome infection group than in the control group (all P values <0.001), whereas high-density lipoprotein–cholesterol was significantly higher in the previous schistosome infection group (P<0.001). In the Atherogenic Index of Plasma quartiles (Q1–Q4), the percentages of subjects with previous schistosome infection were 55.89% (Q1), 25.44% (Q2), 16.33% (Q3), and 18.8% (Q4), respectively (χ2=139.86, P<0.001). A logistic regression analysis based on previous schistosome infection as the independent variable and Atherogenic Index of Plasma as the dependent variable revealed that previous schistosome infection was significantly negatively correlated with Atherogenic Index of Plasma (odds ratio=0.583, 95% confidence interval: 0.440–0.772, P<0.001) after adjustment for body mass index, waist circumference, diastolic blood pressure and uric acid, suggesting that previous schistosome infection is an independent factor associated with Atherogenic Index of Plasma. The potential long-term effects of previous schistosome infection may reduce the Atherogenic Index of Plasma in Chinese men. However, further studies are required to investigate the protective human immune response against schistosome infections. The development of a schistosomiasis vaccine may effectively prevent the development and progression of atherosclerosis.
