Abstract
Opisthorchiasis secondary to Opisthorchis viverrini infection leads to cholangiocellular carcinoma through chronic inflammation of the bile ducts and possibly inducing autoimmunity. It was hypothesized that plasma autoantibodies directed against self-proteins are biomarkers for opisthorchiasis. Plasma from patients with opisthorchiasis was tested using proteins derived from immortalized cholangiocyte cell lines, and spots reacting with plasma were excised and subjected to LC-MS/MS. Seven protein spots were recognized by IgG autoantibodies, and the highest matching scored protein was actin-related protein 3 (ARP3). The antibody against ARP3 was tested in plasma from 55 O. viverrini-infected patients, 24 patients with others endemic parasitic infections and 17 healthy controls using Western blot and ELISA. Immunoreactivity against recombinant ARP3 was significantly more prevalent in opisthorchiasis compared to healthy controls at Western blotting and ELISA (P < 0.05). Plasma ARP3 autoantibody titres were also higher in opisthorchiasis compared to healthy individuals (P < 0.01) and other parasitic infections including Strongyloides stercoralis (P < 0.001), echinostome (P < 0.05), hookworms (P < 0.001) and Taenia spp. (P < 0.05). It was further characterized in that the ARP3 autoantibody titre had a sensitivity of 78.18% and specificity of 100% for opisthorchiasis. In conclusion, it may be suggested that plasma anti-ARP3 might represent a new diagnostic antibody for opisthorchiasis.

Abstract
To investigate the possible involvement of autoimmune mechanisms in the development of hepatosplenic schistosomiasis (HSS), 234 patients with chronic Schistosoma mansoni infections were screened for a wide range of non-organ-specific autoantibodies as well as for antibodies reacting with the GOR peptide and with a liver-specific autoantigen, the hepatic asialoglycoprotein receptor (ASGP-R). Thirty-five (15.0%) were seropositive for antinuclear, smooth muscle or gastric parietal cell antibodies at low titres (< or = 1:80), and 15/176 (8.5%) had anti-GOR, all of whom had concomitant hepatitis C viral (HCV) infections. Anti-ASGP-R was found in 64 (27.4%) of the 234 patients at titres similar to those found in 18 untreated auto-immune hepatitis patients studied concurrently. Anti-ASGP-R seropositivity occurred significantly (P < 0.005) more frequently in patients with HSS (62/190, 32.6%) than in those with hepatointestinal schistosomiasis (2/44, 4.5%), but did not correlate with severity of liver disease or with the presence of the non-organ-specific autoantibodies. Anti-ASGP-R was found significantly (P < < 0.0005) less frequently in HSS patients who had had a splenectomy for portal hypertension (5/86, 5.8%) than in those who had not had a splenectomy (57/104, 54.8%). The findings suggest that liver-specific autoreactivity may play a role in the development of HSS.

Abstract
Thymocytotoxic autoantibodies were demonstrated in sera of C3H/HeJms, C57BL/6J, and ddY mice infected with 50 cercariae of Schistosoma japonicum, using C57BL/6J thymocytes as target cells in the trypan blue dye exclusion test. Kinetic study revealed that thymocytotoxic activity began to increase at week 6 of infection, reached a maximum at 8 weeks, and thereafter decreased gradually. Thymocytotoxic antibodies had an optimal reactivity at 4 degrees C and were sensitive to 2-mercaptoethanol treatment, suggesting that they were immunoglobulin M in nature. The cytotoxicity was completely abolished by absorption with C57BL/6J thymocytes but not with S. japonicum parasites or eggs. The antigen reacting with thymocytotoxic antibodies was found in the thymus, brain, spleen, and, to a lesser extent, kidney and liver. In parallel with the appearance of thymocytotoxic antibodies, the increase of background plaque-forming cells to trinitrophenyl, polyvinyl pyrrolidone, and sheep erythrocytes in the spleen of S. japonicum-infected mice suggested that te induction of thymocytotoxic antibodies may be the consequence of polyclonal B-lymphocyte stimulation by the infection.
