Necatoriasis

Description:

Necatoriasis (necatorosis)  - the helminthosis from group of ankilostomidoz caused by Necator americanus parasitizing in a small bowel; proceeds with the dispeptic phenomena, symptoms of an allergy and development of hypochromia anemia: it is widespread in tropical and subtropical zones.

Necatoriasis symptoms:

The incubation interval of a disease lasts 40-60 days. In most cases the disease proceeds asymptomatically. At heavier current the symptomatology depends on a way of penetration of parasites into an organism. At penetration through skin there is an itch and burning of skin, different rash (erythematic, papular, vesicular, pustular) which can remain within several months. The massive invasion leads to hypostases of extremities. At migration of larvae through respiratory tracts development of the catarral phenomena is possible, there are short wind, rattles, development of bronchitis, pleurisy, pneumonia is possible. At later stage, at hit in digestive tract, the duodenitis with heartburn, absence or strengthening of appetite, sometimes a food faddism (desire is, for example, clay), nausea, vomiting, pains in epigastric and hepatic area, quite often followed by diarrhea develops.

The most characteristic display of a disease – a hypochromia iron deficiency anemia. It is attached by teeth to walls of a mucous membrane of a gut. On site fixings of helminth arise erosion and ulcers to 2 cm in the diameter, at the same time can be shown long intestinal bleedings which cause development of an iron deficiency anemia. Blood protein (hypoalbuminemia) decreases.

The central nervous system is surprised, slackness, lag in intellectual and physical development appears.

Necatoriasis reasons:

The necatoriasis activator – a nekator (Necator americanus) parasitizing in a small intestine of the person is more often in a duodenum. Nekator has no teeth in the oral capsule, instead of them at him two cutting plates. Eggs of both helminths of an oval form.
Necator americanus register in Asia, Africa and America

Treatment of the Necatoriasis:

At the expressed anemia (hemoglobin is lower than 67 g/l) use iron preparations, transfusions of eritrotsitny weight. Deworming is carried out by Naftamonum, Kombantrinum or levamisole. Naftamonum is appointed on an empty stomach within 2-5 days. A single dose for adult 5 g. For elimination of bitter taste and nausea it is better to give drug in 50 ml of warm sugar syrup. Kombantrinum (Pyrantelum) appoint in a daily dose 10 mg/kg in two steps after food, and levamisole (decarice) in a daily dose of 2,5 mg/kg in one step. Treatment by these drugs continues 3 days. Efficiency about 80%.
