Among the many helminthic infestations (more than 300 species), one of the most unpleasant is parasites in human blood. At the same time, the symptomatology of the pathology is so diverse that a person can treat a non-existent disease for years, and the enemy cannot be recognized by sight. We will understand below what types of helminths can live and multiply in human blood, as well as what is the clinical picture of pathologies.

In humans, several types of parasites can be detected in the blood. Moreover, each of them carries potential harm to the body. So, a person can be a biological carrier of such helminths:

  • Munsonella. Worm eggs are transmitted to humans through the bite of wood lice. In this case, the parasite becomes sexually mature individuals only in the human bloodstream. The disease that such a parasite provokes is called mansonellosis.
  • Trypanosome. They are the simplest pathogenic protists. When it enters the blood of a person, it sticks to leukocytes and erythrocytes. They feed on carbohydrates and glycoproteins obtained from their host's blood plasma. Bloodsucking insects are intermediate carriers of tryponasoma. Man becomes the final habitat. Basically, the multiplication of this worm occurs in the lymph nodes and in the spinal cord. It is noteworthy that the parasite has a protective shell that prevents the human immune system from recognizing it.
  • Nematodes (round parasites). These include whipworm, roundworm, pinworm. The human body for such worms is an intermediate environment. The carriers of the helminth are mosquitoes and bedbugs.
  • Hemosporidia. The simplest, which reproduces asexually. The parasite infects red blood cells.
  • Toxoplasma. A parasite that, with strong immunity, leaves the human body on its own within 3-8 months. The most dangerous helminth for pregnant women in the 1-2 trimester of gestation.
  • Guinea worm. A complex and dangerous helminth that lives in several countries of Central Asia. It is able to grow to enormous sizes in the body of its biological host. Remove such a helminth called "subcutaneous dragon" only by surgery.
  • Plasmodium malaria. It mainly parasitizes in erythrocytes, but it strongly affects the human liver. The helminth feeds on hemoglobin. Growth and reproduction occurs exclusively in the bloodstream.

In addition to the above types of helminths, there are those that parasitize in the intestines, but in a certain cycle of their life they enter the bloodstream, disrupting it. These worms include:

  • Amoeba. It is mainly attached to the intestinal walls and feeds on blood cells.
  • Wide ribbon. When released into the bloodstream, it seriously disrupts blood flow.
  • Schistosoma. Capable of blocking the lumen of blood vessels, entering the bloodstream.
  • Ankylostoma. It not only circulates with the blood throughout the body, but also releases a substance into the blood that reduces its clotting. As a result, a person has a protein deficiency.
  • Echinococcus. Provokes anemia by feeding on human blood.

The appearance of parasites in the blood of a person provokes a variety of symptoms. But at the same time, it is worth knowing that infection occurs in the following ways:

  • Bites of animals infected with helminthic infestation;
  • Bites from blood-sucking insects;
  • Penetration of parasites through the damaged epidermis in humans;
  • Transfusion of contaminated donor blood;
  • Through dirty hands, vegetables, fruits and meat products.

When the blood is damaged by a helminthic infection, the patient develops the following symptoms:

  • Allergic skin rashes due to decreased immunity and poisoning of the body by the waste products of helminths;
  • Soreness in muscles and joints due to toxins;
  • Anemia and anemia;
  • Disorders of the nervous system and, as a result, dizziness, hallucinations, nerves, sleep disorders;
  • Frequent colds;
  • Soreness in the area of ​​the heart, liver, abdomen;
  • Weight loss for no other apparent reason;
  • Hair loss and brittle nails, pallor of the skin.

To identify individuals parasitizing in the patient's blood, it is necessary to use one or several modern diagnostic methods. These are:

  • Immunoassay blood test (ELISA). Allows you to identify parasites by the reaction of antibodies to antigens in the blood. It is not a method for determining the type of parasites in the human body, but only allows you to confirm the diagnosis suggested by the attending physician.
  • Serological analysis of the patient's blood and feces. Allows you to identify helminth eggs at the stage of their reproduction. It is informative only by 30%, since the biomaterial can be collected during the absence of egg laying by the parasite.
  • Hemoscanning. An analysis that allows you to assess the condition of erythrocytes and determine their mobility. Also, with this diagnostic method, it is possible to identify the presence of glued erythrocytes, which is a confirmation of the presence of worms in the blood.

In addition to the listed diagnostic methods, the attending physician must take into account the patient's medical history and take into account all conditions that could lead to a potential infection with helminthic invasion (rest in Africa and Asia, a raw food diet, work in potentially dangerous conditions).

To completely get rid of parasites in the blood, it is necessary to undergo a complex multi-stage treatment with anthelmintic drugs. In this case, the effectiveness of therapy depends both on the correctness of the diagnosis and on compliance with all the prescriptions of the attending physician. The principle of action of all modern drugs is to immobilize individuals of the parasite and in their subsequent removal from the bloodstream. It is worth knowing that only a specialist can prescribe symptoms and treatment. In this case, the dosage of taking drugs should also be selected by the attending parasitologist or infectious disease specialist. The following drugs can be used to treat helminthic invasion in the blood:

  • Piperazine and Vormil;
  • Azinox and Helmintox;
  • Nemozole and Fenasal.

Throughout the therapy, you should adhere to a special diet that excludes carbohydrates (including simple ones), meat and fish, and alcohol in any form. Food should be as simple and digestible as possible.

Prevention

To avoid helminthic invasion, it is necessary to follow basic rules of personal hygiene, which will be preventive measures of infection. These rules are:

  • Thorough hand washing after each visit to the toilet, contact with animals, handling meat and fish, and after working in the garden and vegetable garden.
  • Thorough washing of vegetables, fruits and herbs before use.
  • Fighting insects in the house (flies, bugs, cockroaches, mosquitoes, etc.).
  • Timely and regular treatment of pets with anthelmintic drugs.
  • Swimming only in special reservoirs intended for recreation of the population.
  • Eating high-quality clean water (boiled or specially purified).

Compliance with such simple rules will allow you to insure your health and life against serious problems that can be provoked by parasites. Remember, your health is only in your hands.
