Angiostrongilyoz (Angiostrongilidoz, angiostrongylidosis) — the helminthosis from group of nematodoses which is characterized by damage of a brain.
The parasite causes eosinophilic meningoentsefalita. Quite often larvae find in spin and a brain, an anterior chamber of an eye.
Having got into TsNS, parasites perish over time. However they manage to cause pathological changes which in hard cases become the reason of permanent neurologic disturbances and even death. Migration of larvae is followed by proteolysis, formation of eosinophilic infiltrates and hemorrhages. In the subsequent around the died parasites the centers of a necrosis and a granulematozny inflammation are formed. The incubation interval makes from 2 to 35 days.
The severe headache (with the sudden or gradual beginning) which can be localized in a forehead, a nape or temples is characteristic. Also the stiff neck, nausea, vomiting, paresthesias are noted. Fever, damage of third and other cranial cranial nerves, epileptic seizures, paralyzes, confusion of consciousness are occasionally observed.
Often drowsiness develops. The patient is in a fever, body temperature increases to 38 — 39 'Page. Such state can proceed up to 4 weeks.
In hard cases death is possible.
The activator — Angiostrongylus cantonensis nematode — a parasite of rats. Larvae of helminth are allocated to the environment with a stake. Fresh-water and land mollusks — intermediate owners, shrimps and crabs — so-called reservoir owners.
Diseases are endemic in many countries of Southeast Asia (Vietnam, Thailand, Malaysia, Indonesia, China, Japan, Philippines), in the Pacific region (Australia), Central and South America (Cuba, Puerto Rico, Brazil), Africa (island of Madagascar), the Middle East (Egypt).
The person catches at consumption of different types of mollusks, crabs and shrimps in a crude or half-baked look.
For treatment of a pulmonary angiostrongilyoz Levamisole (for example Citarin – L) in a dose of 7,5 mg/kg of live weight subcutaneously within 2 days is recommended. Usual side effect for this drug – hypersalivation reduction, vomiting, etc. Fenbendazole (for example, Panacur) in a dose of 20 - 50 mg/kg of live weight within 5 days is better transferred.
