ALB and schistosomiasis: We found that three biochemical indicators of liver injury including serum levels of aspartate transaminase (AST, PT-test = 1.84 × 10-6), serum levels of albumin (PT-test = 4 × 10-13), serum levels of hyaluronic acid (HA, PT-test = 2.62 × 10-17) and ascites grade (Px2 = 3.52 × 10-14) showed significant differences between the PVD normal (n=745) and abnormal (n=239), which means that these indicators were related to the progression of schistosomiasis (Table 1).
