Content
Etiology. Epidemiology
The causative agent of trematode Metagonimus yokogawai (Yokogawa, 1911) with a length of 1-2.5 mm, width of 0.4-0.7 mm. The body is covered with small spines, the abdominal sucker is merged with the mouth. Eggs have dimensions of 0.023–0.029 x 0.014–0.018 mm with a lid on one and a thickening of the shell on the other end. Adult parasites are localized in the small intestine of humans, dogs, cats. The development takes place with the change of two hosts - freshwater mollusks and various species of fish (trout, Ussuri whitefish, Amur bream, carp, crucian carp, uplift, etc.).
Human infection occurs when eating raw fish and accidentally swallowing its scales. The disease is common in China, Korea, Japan, in the Amur basin, as well as on Sakhalin.
Pathogenesis
Sensitization of the organism with helminth antigens and damage to the mucous membrane of the small intestine by the larvae and adults of the parasite play a role.
At an early stage, febrile, pruritus, eosinophilia are characteristic of the person suffering from metagonimosis. A little later develop enteritis, manifested by pain in the upper abdomen, nausea, prolonged diarrhea. The duration of the invasion is about 1 year.
Treatment
The diagnosis is based on the detection of helminth eggs in the feces.
Patients are hospitalized, treatment is carried out with an ether extract of male fern, as well as naphthamone and praziquantel.
The prognosis is favorable.
