    Strongyloidosis - helminthiasis (nematodes), parasitic disease, occurring with lesions of the gastrointestinal tract and allergic manifestations.

    Pathogen - small threadlike roundworm (nematode)
    Strongyloides stercoralis
    (Ugritsa intestinal). Male 0.7 mm, female - 2.2 mm. Eggs are oval,
    transparent, size 3-5x3 m. The life cycle takes place with a change
    free-living and parasitic generations. During migration ugritsy
    reach sexual maturity; female fertilization occurs in the lungs.
    Mature individuals of parasites in the intestinal mucosa (usually
    liberkyunovyh glands in the duodenum), and
    massive infection may penetrate the mucosa
    pyloric part of the stomach, small and large intestines, bile and
    pancreatic ducts. Of the eggs laid in the intestines out
    rhabditiform (non-invasive) larva to 300-400 microns allocated
    with feces. In unfavorable conditions, after 1-4 days the larvae
    develop in filariform (infected) form, and enabling - in
    adults able to give rise to a generation as rhabditiform so
    filariform and larvae.

    Disease
    widespread. Most cases are recorded in
    tropical countries. In temperate countries, the greatest risk
    are mines and tunnels with a warm and humid climate. A source
    infection - a sick man. The main mode of transmission - fecal-oral
    and contact.




    How is strongyloidosis

    What strongyloidosis
    On
    characteristic of the early stages of allergic skin and lungs, on
    later dominated by lesions of the gastrointestinal tract. For minor infections observed asymptomatic (30% of all patients). Migrating larvae
    the body causes fever, rash papular (small
    flat papules, nodules), itching, hives and swelling.

    Intestinal stage is accompanied by abdominal pain
    varying intensity (in severe cases - Acute pain with the rise
    body temperature, anemia, cachexia (emaciation of the body)), nausea, vomiting, diarrhea with
    mucus. In severe cases, a chair - a putrid odor, contains blood,
    mucus and undigested food residue. Pulmonary lesions resemble
    those in ascariasis and hookworm.

    At risk -
    Patients with compromised immune systems. Characterized by heavy
    enterocolitis, liver, heart, lungs and central nervous system. Symptoms:
    severe abdominal pain, diffuse pulmonary infiltrates,
    ileus, meningitis, shock, sepsis.

    Methods of research - in the early phase of the migration detect larval parasites in sputum.

    On
    intestinal helminth larvae detected in the content and
    freshly feces (after taking laxatives) by Berman.

    at
    strongyloidiasis is suspected in the case of the first negative result
    the study was repeated 3-5 times at weekly intervals.



    Treatment and prevention of strongyloidiasis

    • Mebendazole 200 mg (children 100mg) p 2 / day for 3 days.

    Prevention:

    • Compliance with the rules of personal hygiene
    • Decontamination of the mines and land
    • Sanitary and educational work among the population in endemic areas
    • One month after the treatment is carried out control scatological study.
