Among the many diseases caused by various parasites, opisthorchiasis has a special place. Opisthorchiasis – a disease that affects the liver and pancreas. These organs are affected as a result of infection human intestinal worms – opistorhami. Infection occurs through the diseased fish. The causative agent of this disease is a cat fluke.
Most of this parasite is common in the Ob, Irtysh, Volga and Kama rivers. Excretion a sick person or animal parasite eggs get into water, ingested snails and other mollusks, multiply there and go into the water already in the form of larval cercariae. Cercariae penetrate in cyprinids, where live up to the moment when the fish are not caught. Man, eating bad fried or undercooked fish gets to live larvae into the duodenum. From there the larvae migrate to their favorite places – the bile ducts liver and pancreas.
After 3-4 weeks the parasites mature and begin to lay eggs. Alarming state of affairs in terms of incidence of opisthorchiasis, especially in the Tyumen region, where in 2007 only victims opisthorchiasis has more than 4,000 area residents and has not yet achieved a positive clinic. Pathogens opisthorchiasis live in such delicious representatives of the fish population as roach, rudd, ide, dace, rudd, bream, crucian carp, tench and others. And still the main cause of the disease is non-compliance with hygiene. Let's split the fish are well treated thermally and destroyed all larvae. But if you cut the vegetables for a salad on a poorly washed fish cutting board, then the portion of the parasites you get for sure. On this occasion, well said Tatyana Stepanova, Director of the Institute of Regional Infectious Pathology Rospotrebnadzor Tyumen region. Its meaning words is reduced to what we can determine the level of awareness of the population in terms of incidence of parasitic disease – the higher the first, the lower the latter. A little about the symptoms of the disease opisthorchiasis. The majority of patients the early stage of the disease does not manifest or observed only a slight increase in blood eosinophil. The incubation period is 2-3 weeks. The disease manifests itself suddenly, the patient begins fever and pain in the right hypochondrium. This state lasts from one to three weeks, it is accompanied by a high temperature of 39 degrees and above. Opisthorchiasis in the chronic form makes itself felt pain in the upper abdomen, mainly in the right hypochondrium, nausea, aversion to greasy foods, dryness and bitterness in the mouth. Very often there are cases of depression. The people are of the opinion that it is impossible to cure completely opisthorchiasis, but it's not true. Main – apply a comprehensive method of treatment because of chronic opisthorchiasis affected organs digestive system. Apply cholagogue, enzyme preparations, affecting the tone and motility gastrointestinal tract; dietetics. The most effective tool for the specific treatment is praziquantel. Treatment is carried out at the rate of daily doses of 40-75 mg per 1 kg of body weight and assigned to receive 3.3. Children under 2 years of praziquantel is not recommended to take.
