As soon as they penetrate in the skin of the host, the larvae of ancilostomideos can provoke, in the place of the penetration, traumatic injuries, followed for vascular phenomena. After some minutes, appear the first signals and symptoms: a sensation of bite, hipertermia, prurido and edema resultant of the inflammatory process or urticariforme dermatitis. Depending on the amount of worms, the infectado one can or not develop the illness. This is detected when the lost blood due to infection, starts to intervene with the life of the patient. The sanguine loss is an important cause of ferropriva anemia, not only because of its frequency, but also because the diagnosis and the handling of the hemorrhagic injury are of great importance for the process of cure and welfare of the patient. With the purpose esteem the effect of the sanguine loss in rocking of the iron, 1 ml of blood contains 0,5 approximately mg of iron. Thus assumed, a negative rocking can be configured with small loss of blood, as of 3 the 4 ml/dia (1,5 the 2 mg of iron). The gradual loss of iron, through the injury of the intestinal mucosa, caused for the espoliadora action of the parasite, causes the clinical picture of ferropriva anemia, what it can intensified depending on the degree of infection for the parasite, beyond ferric losses also has the proteinic loss.
In the ancilostomtica anemia, the iron lack leads to the deficient production of hemoglobina. Consequently, the oxygen transport becomes insufficient. In this manner, the organism cannot synthecize necessary proteins, in virtue of the lack of the element most important in its metabolism, the oxygen. The ancilostomtica anemia is a ferropriva anemia that if it installs in insidioso way has a parasitado organism, and generally is decurrent of some reinfeces. This is the natural consequence of environment where the individuals of low partner-economic classroom and the agricultural zone live.
