ABSTRACT=<sec id="sec1"><title>Background and aims</title><p>Hepatitis B virus (HBV) infection is the most common cause of liver cirrhosis. Portal venous system thrombosis (PVST) is a major complication of liver cirrhosis. Recently, it has been shown that C-type lectin-like receptor 2 (CLEC-2) and galectin-1 participate in the activation and aggregation of platelets, thereby promoting the development of thrombosis. This cross-sectional study aims to evaluate the association of serum CLEC-2 and galectin-1 levels with PVST in patients with HBV-related liver cirrhosis.</p></sec><sec id="sec2"><title>Methods</title><p>Overall, 65 patients with HBV-related liver cirrhosis were included, of whom 23 had PVST and 42 did not have. Serum CLEC-2 and galectin-1 levels were measured using enzyme-linked immunosorbent assay kits. PVST was assessed by contrast-enhanced computed tomography and/or magnetic resonance imaging scans. Subgroup analyses were conducted according to the degree and location of PVST.</p></sec><sec id="sec3"><title>Results</title><p>Patients with PVST had significantly higher serum CLEC-2 (<italic>p</italic> = 0.006) and galectin-1 (<italic>p</italic> = 0.009) levels than those without. Patients with partial/complete PVST or fibrotic cord (<italic>p</italic> = 0.007; <italic>p</italic> = 0.002), but not those with mural PVST (<italic>p</italic> = 0.199; <italic>p</italic> = 0.797), had significantly higher serum CLEC-2 and galectin-1 levels than those without PVST. Patients with superior mesenteric vein thrombosis had significantly higher serum CLEC-2 (<italic>p</italic> = 0.013) and galectin-1 (<italic>p</italic> = 0.025) levels than those without PVST. Patients with main portal vein thrombosis had higher serum CLEC-2 (<italic>p</italic> = 0.020) and galectin-1 (<italic>p</italic> = 0.066) levels than those without PVST, but the difference in serum galectin-1 level was not significant between them.</p></sec><sec id="sec4"><title>Conclusion</title><p>Serum CLEC-2 and galectin-1 levels may be associated with the presence of PVST in HBV-related cirrhotic patients, but this association should be dependent upon the degree of PVST.</p></sec>
