The food-borne liver trematode Opisthorchis felineus causes severe liver damage, including fibrosis. This study shows a comparison of the characteristics between cholangiofibrosis and periductal fibrosis in infected people and in the golden hamster as an experimental model. Comparative evaluation was carried out regarding collagen composition, the number of basic-producing cells, and extracellular-matrix degradation. The results revealed that characteristics of chronic opisthorchiasis due to O. felineus infection in humans and in Syrian hamsters are similar and include well-pronounced development of fibrotic complications in the liver parenchyma. Besides, a difference in fibrogenesis development was demonstrated between chronic O. felineus infection and noninfectious cholecystitis. In this study, we for the first time compared fibrogenesis between humans and model animals against the background of chronic O. felineus infection.

Background: Epidemiologically important food-borne trematodes Opisthorchis viverrini and Clonorchis sinensis are recognized as biological carcinogens of Group 1A, while Opisthorchis felineus is in Group 3 as noncarcinogenic to humans. Mechanisms of the biological carcinogenesis are still elusive. Some studies highlight chronic inflammation as a key factor and common pathway for cancer initiation and progression.

Article Synopsis
  • * In hamster models, researchers found that liver damage varied by species, with O. viverrini linked to a specific type of cancer and O. felineus and C. sinensis causing similar liver fibrosis.
  • * A significant correlation was identified between liver and kidney damage, suggesting a connection in the disease progression caused by these parasites. Future research is encouraged to understand serious complications and the role of other factors in liver fluke-related carcinogenesis

The risk of hepatobiliary complications in Clonorchis and Opisthorchis infection: A systematic review and meta-analysis.

Clonorchis sinensis, Opisthorchis viverrini, and Opisthorchis felineus are the three important liver flukes, infecting approximately 25 million people worldwide. Despite the reporting of the carcinogenesis of these liver flukes, the comprehensive and systematic analysis of the pathogenicity of these parasites in hepatobiliary system is still not sufficient. We conducted a thorough systematic review and search for published articles in MEDLINE, Embase, Cochrane Library, China National Knowledge Infrastructure databases until early 2024.

Article Synopsis
  • A study focused on a 2022 outbreak of Opisthorchis felineus infection in Central Italy, tracing 67 individuals with 47 diagnosed cases linked to a lakeshore restaurant, highlighting patterns from previous outbreaks between 2003-2011.* -
  • Symptoms included fever in most patients, with 16 needing hospitalization; diagnostic tests revealed a high percentage of parasitic eggs in feces and significant lab abnormalities, such as eosinophilia.* -
  • The study emphasizes the difficulty in diagnosing asymptomatic cases and raises concerns about the ineffectiveness of albendazole as a treatment option, advocating for better control measures in endemic regions.*
