Chronic opisthorchiasis - as a systemic pathology and issues of comorbidity. Clinic, diagnosis, treatment

The article shows that chronic opisthorchiasis is a systemic and comorbid disease caused by the trematode Opistorhis felineus when consuming fish of the carp family that is not sufficiently salted or heat-treated. The systemic nature of the disease lies in the fact that with opisthorchiasis, the organs of the helminth’s permanent habitat are affected; organs located on the paths of its migration, as well as intact organs and systems. The described syndromes and symptoms indicate the comorbidity of the pathology. The author describes a three-stage system for the treatment of chronic opisthorchiasis, including gentle specific therapy.
