In the subtropics and tropics can often find the disease leishmaniasis. The disease is transmitted to humans through mosquito bites. The causative agent - protozoa of the genus Leishmania. Was this pathology in 88 countries, 72 of which are developing countries.

disease leishmaniasis

Quick feature

Live and develop Leishmania in humans or different animals. Quite often, they find foxes, jackals, dogs, some rodents. To date there is no information about the period of infectiousness of animals and humans. We only know one thing. If the skin or blood is the parasite, the host is the source of contamination.

Very dangerous to live in the organism Leishmania. They live in the spleen and liver. Sometimes the parasites settle in the bone marrow. As noted above, this disease isn't just a human beach. Often found leishmaniasis in dogs, domestic rodents.

Historical background

Leishmaniasis was discovered by P. F. Borovsky in 1898. Finding parasites in smears penzenskoy ulcers, the doctor first described them. That is why the disease is called leishmaniasis, "the disease borovskogo". Much later the pathogen will be assigned to a specially created genus Leishmania. And transmission of diseases was established only in 1921.

Today, the disease leishmaniasis is a rare disease that you can catch only in the countries of the tropics, subtropics.

What is a parasite?

A More common disease is cutaneous leishmaniasis. The causative agent of the disease – Leishmania. To the naked eye to examine the parasite impossible. Its dimensions are microscopically small. Length Leishmania - about 3 microns. The parasite has a spherical or oval shape at the middle is the core. The front part contains the Leishmania flagellum, the back is blepharoplast.

The parasite Feeds on the contents of the cells of animals, humans. Protozoa multiply by dividing. In the front there is no flagellum. So begins the process of reproduction, which is an infection of the body.

Propagation

The Disease is easily transmitted. The scheme is simple enough. Insects, bites an infected human or animal, carry a parasite in a healthy body. After a time the patient is diagnosed the disease leishmaniasis.

leishmaniasis symptoms

Pathogens there are several dozen species. About twenty of them pose a danger to human life. They often cause cutaneous leishmaniasis. Complicates treatment of the disease is the fact that parasites are absolutely not sensitive to antibiotic therapy.

Disease Vectors are mosquitoes. After biting an infected person become infected with insects. And a week later already represent the source of the disease. These blood-sucking insects infect the patient that skin form of the disease. The human body can develop antibodies. Once you recover from this form the patient is immune to the disease.

Cutaneous leishmaniasis the disease is able to spread, not only through the blood of the mosquito. The insect can be infected ulcer with discharge.

Classification pathology

There are three types of disease:

  1. Cutaneous Leishmaniasis. the Disease is manifested by extensive lesions manifested papules.
  2. Leishmaniasis cutaneous-mucous. For this disease is characterized by ulcers on the mucous membranes of the mouth, throat, nose.
  3. Visceral Leishmaniasis. This form is diagnosed if Leishmania gets into the lymphatic vessels. With the flow of the fluid it spreads throughout the body. Affects the internal organs. This is mainly spleen, lungs, heart, liver. This form does not have the capacity to build in subsequent immunity to the disease.

Clearly shows the disease leishmaniasis photos below. It is represented by the cutaneous form of the disease.

Share the pathology, depending on who were the reservoir and source of infection. Thus, the cutaneous and visceral leishmaniasis can be of two forms:

    • Anthroponosis the source of the disease is;
    • Zoonotic - a pathogen passes from animals.leishmaniasis treatment

Symptoms of visceral form

Describes the form of the long incubation period. From the moment of infection until the first signs of the disease may take from 20 days to 5 months. Develops gradually visceral leishmaniasis. Symptoms in the initial stages the following:

  • Characterized by General weakness;
  • Pale skin;
  • Loss of appetite until its complete absence.
  • The size of the spleen slightly increased;
  • Marked apathy;
  • Body temperature is increased (the maximum value is 38).

The progression of the disease is characterized by the accession of new symptoms. Marepineta attempts to aggravate the treatment of leishmaniasis. Symptoms in humans are added the following:

  1. Significantly increased temperature (reaching 40). This characteristic has wave-like character. The patient alternates hyperthermia with normal indices.
  2. Cough. This symptom occurs in lesions of the respiratory apparatus.
  3. Enlarged lymph nodes. Identified during the inspection. The increase was greater near the affected organs.
  4. Soreness of the liver, of the spleen during palpation.There has been a significant increase in these organs.

If you don't start a fight with pathology, continues to progress leishmaniasis. Treatment much more complicated. The patient's condition continues to deteriorate.

  • Exhaustion of the patient;
  • The spleen becomes enormous size;
  • The surface of the skin, dry, very pale;
  • Frequent dizziness;
  • There are swelling in the legs;
  • Frequent heartbeat;
  • Increases the volume of the abdomen (abdominal fluid accumulates);
  • May cause diarrhea;
  • Disturbed potency.

The Final stage is characterized by reduced muscle tone, appearance of swelling of entire body, pale codname covers. As a result, the patient dies.

Sometimes diagnosed chronic disease. Signs of illness are almost there. Such a clinic can occur if the seeding leishmaniae internal organs is minimal.

Symptoms skin disease

This form is often recorded in Saudi Arabia, Afghanistan, Brazil, Syria, Iran, and Peru. The incubation period can last from 10 days to 1.5 months.

During the initial stage of the skin surface there is a formation characteristic of the insect bite. This place with a slight boil, resembling tubercle. Palpation of this location causes painful discomfort. After one to two weeks in the center of the tubercle there is a area of dead tissue - necrosis. This place has a black color. Soon it becomes an ulcer. From the center of the wound yellow-red fluid pus.

Near the initial sores begin to encounter secondary tubercles. Acquiring the shape of the wound, they eventually merge. On the skin surface and form one large ulcer.

You Can increase the regional lymph nodes of the patient with the diagnosis of "disease borovskogo". Cutaneous leishmaniasis is characterized by the wounds healing over 2-6 months. And the sores left scars.

Thus, the main symptoms of skin disease are:

  • The appearance of bumps – Leishmania;
  • Destruction of the skin in the place of a tubercle;
  • Expression;
  • Wound healing and scar formation.

Symptoms of skin and mucous forms

This type of disease is leishmaniasis in its manifestations practically does not differ from skin disease. The only difference is the spread of pathology to adjacent mucous membranes.

Causes this form of the parasite found in the New world. Skin and mucous membrane pathology is initially reminiscent of the bite of the animal. Subsequently, patients are involved mucous membranes. Sometimes, the disease deforms the face.

For this pathology to the above symptoms of cutaneous leishmaniasis are added the following features:

  • Runny nose;
  • Stuffy nose;
  • Difficulty swallowing;
  • Epistaxis;
  • Erosions and ulcers in the mouth (lips, gums, tongue);
  • Ulcers in the nasal cavity.

Doctors have identified two types of complications of this form. If joins secondary infection illness, the patient may develop pneumonia. In case of involvement of the respiratory system can be fatal.

Diagnosis of disease

In those countries where the disease is widespread in patients with a combination of clinical symptoms and the results of the analyses suggest the existence of leishmaniasis.

leishmaniasis cutaneous

Other patients need for the final diagnosis, to conduct a study of tissue under a microscope to identify parasites or blood test that can identify antibodies. Known in medicine a skin test, called the test "black leather". Such a study is not perfect, therefore, for the diagnosis of the disease is almost never used.

You Should not forget that many diseases can cause weight loss, fever, organ enlargement, skin lesions. Most illnesses can mimic the symptoms of leishmaniasis. It's typhoid fever, malaria, Chagas disease, toxoplasmosis, tuberculosis, syphilis, histoplasmosis. Therefore, a final diagnosis is possible only by excluding other pathologies.

If you suspect cutaneous leishmaniasis diagnosis begins with a careful collection of epidemiological anamnesis. It turns out the fact of stay of the patient in an area known for outbreaks of disease.

Tests to confirm the diagnosis, carry out the following:

  • Examination of material from ulcers and tubercles;
  • The study of blood (with Romanovsky-Giemsa);
  • Bone marrow puncture;
  • Liver biopsy, lymph nodes, and spleen;
  • Biological sample;
  • Serological tests (IFA, RSK).

Treatment Methods

As previously mentioned, antibiotics in the treatment of diseases ineffective. They are assigned only one case - if for leishmaniasis associated bacterial infection. For different forms of the disease are matched by its methods of dealing with illness. If the patient is diagnosed cutaneous leishmaniasis, treatment is based on the use of local medicines. The visceral form needs a series of injections.

The Disease, occurring in mild form, in special treatment are not required. This disease after a certain period of time passes by yourself. While the unpleasant effects he leaves.

If the patient has low immunity, he is definitely assigned therapeutic treatment. Because the disease is difficult. The lack of the necessary therapeutic measures for the patient is fraught with serious consequences and sometimes death.

The Disease,occurring in severe form, involves surgical intervention. During the operation, the patient removes the spleen.

Treatment of skin pathology

Methods of struggle depend on the shape, stage and progression of such diseases as leishmaniasis. Treatment may include the following methods:

  • Drug therapy;
  • A surgical method;
  • Physiotherapy treatments;
  • Chemotherapy.

The Surgical technique used, if the surface of the skin, there is one small lesion. Such an ulcer excised surgically.

diagnosis of cutaneous leishmaniasis

For therapeutic purposes can use the following physiotherapeutic methods:

  • Elimination of pathology laser;
  • Cryosurgery is the site of the lesion is destroyed by cold;
  • Current treatment - electrocoagulation.

Radical therapies are combined with medicines, antibacterial and anti-inflammatory action.

Medical treatment is based on the following drugs:

  1. "Metronidazole". The course of treatment is usually about 10 days. Perinatal drug is taken three times a day. Single dose-250 mg.
  2. Drugs pentavalent antimony. This is often the drugs: “Saucerman”, “Glucantim”. They are administered with the ineffectiveness of medication "Metronidazole" applied for 2-3 days. These medications are injected intramuscularly and topically. Recommended dose-400-600 mg of medication a day.
  3. “Pentamidine”. This tool is the drug of choice. It is used twice a week, 2-4 mg/kg.
  4. Local antiseptic, disinfectant ointments. They lubricated the affected areas. Effective for this pathology “Kanamicina”, “Gramicidines”, “Rivarola" (1%), “Abraimova" (1%) ointment.
  5. ‘Furacillin”. Recommended gadgets from this solution.

The Medication is often defined courses. Between them, it is recommended to take a break lasting about 2-3 weeks. The dosages given above - average performance. During the treatment standards are selected for each patient individually.

At the first stages of the disease Antiprotozoal drugs (“Saucerman”, “Glucantim”) are injected directly into the affected area. Such injection is advantageously carried out about 3-5 days.

Treatment visceral form

With this form of disease, popular 3 groups of drugs:

  1. Tools pentavalent antimony. Often therapy includes “Saucerman”, “Pentostam”, “Notebase”, “Glucantim”. The drug is administered intramuscularly or intravenously. The dosage of these medicines depends on the age. The maximum rate consists of 20 injection.
  2. Scented diamidine. This medication “Pentamidine”, “Stilbamidine”. Such agents are appointed in ineffective treatment of the above-mentioned pentavalent antimony drugs. The patient will need to pass 3 courses. Between which there is a break in 10 days.
  3. “Amphotericin b". About this medication it is, if all of the mentioned drugs do not provide the necessary therapeutic effect. The duration of therapy may be around 8 weeks.

    leishmaniasis cutaneous pathogen

The treatment may include:

  • Antibacterial drugs: “Metacycline”, “After”;
  • Antifungal agents: “Ketoconazole”;
  • Antimicrobial drugs: "Furazolidone".

Folk medicine

Effective methods can be used by healers to eliminate the disease. Just keep in mind that such methods can not replace the therapy prescribed by the doctor when the disease "leishmaniasis cutaneous". Treatment of folk remedies should be thought of as additional methods to combat disease.

When the cutaneous form of the disease is recommended:

  1. Use of tonics. It is useful to take tincture of aralia, schisandra, ginseng, Eleutherococcus, levzei. They perfectly enhance the protective forces of the organism, contribute to overall improvement. Appropriate any of the drugs consumed twice a day drops to 30.
  2. Freshly squeezed juices. Very useful for patients to use drinks of carrot, potato, cabbage.

Using such methods, always consult your doctor. Some remedies have contraindications and is cure can deliver unpleasant consequences.

Prevention of disease

The Main measures of prevention of the disease is the destruction of sources of infection - rodents and mosquitoes in their breeding areas.

The Seed of the places inhabited by rodents, is within 15 km from the village, which is prevention. This distance corresponds to the distance of the flight of mosquitoes.

To prevent the spread of skin disease, you must prevent the breeding of homeless animals. Home should always be evaluated for infection.

Preventive measures include:

  1. Landscapingresidential zones. Should eliminate breeding areas for mosquitoes and rats.
  2. It is Recommended to eliminate the landfill.
  3. To prevent the flooding of basements.
  4. In a Timely manner to repair all the pipes.
  5. Regularly should be preventive pest control residential and basements.

To Protect the house from blood-sucking insects allow tight mosquito mesh. In addition, it is recommended to use repellents. These simple methods will help to prevent the occurrence of the disease leishmaniasis.

leishmaniasis cutaneous and visceral

Prevention when visiting places that are dangerous based on specific immune therapy. Unfortunately, until today, the current vaccine against the illness be developed.

Conclusion

In most cases the prognosis is favorable. If we talk about cutaneous leishmaniasis, it is rarely fatal. Although often leaves behind disfiguring scars. If proper therapy of the visceral form is almost always fatal as a result of severe malnutrition or organ failure. This can be avoided, but only in a timely manner by fighting with an unpleasant pathology under the guidance of a competent doctor.
