Toxocar larvae, affecting the internal organs of a person, carry a serious threat to the patient infected by them. Their main danger is reduced to the occurrence of systemic allergic reactions with multiple characteristic manifestations. In addition to this, they can significantly worsen their functional activities when they settle in vital organs and encapsulate them. Infection by them occurs as a result of ingestion of invasive eggs having microscopic dimensions into the intestine. The larva hatched from them penetrates into the intestinal wall and begins a journey through the human body with the blood flow, causing the appearance of various severe pathologies.
Most often there is a visceral form of toxocariasis, which is characterized by the defeat of internal organs. On the Internet, there are many photographs that clearly demonstrate the danger that arises when a patient develops this type of infestation. Also on the site you can find a photo of eggs of these parasites, which is made under a microscope. Only in these photographs can be considered as an unfertilized egg Toksokara, and an egg with a developing larva in it, since it is impossible to see them with the naked eye because of the microscopic size.
Visceral Toxocarose
Many are interested in what organs are affected by the larvae of parasites in this form of invasion and with what signs it occurs. The visceral or systemic type of helminthiosis is characterized by the ingress of a large number of toxocar eggs into the human body. Out of them, in the small intestine, larvae emerge, which are carried along the body by the current of blood and settle in the pancreas, lungs, liver, heart and other vital internal organs. Thus there is a following symptomatology:
- Abdominal syndrome( stool disorders, flatulence, vomiting, pain in the abdomen);
- An allergy that corresponds to vesicular and urticaria skin rashes, which look like bubbles with clear liquid;
- Enlargement of various lymph nodes;
- Hepatic syndrome, expressed in the compaction and soreness of the enlarged liver;
- Diseases of the respiratory system beginning with simple catarrhal phenomena and up to a severe asthmatic state. In patients with a visceral form of invasion, when infected with larvae toxocar respiratory organs can develop chronic bronchitis, and there is always an asthmatic component( cough with shortness of breath);
- Acute infectious-toxic syndrome( rising in the evenings of temperature, lethargy and weakness).
In case of visceral toxocariasis there may be a lesion of pancreatic larvae that flows into pancreatitis and the brain. In the latter case, helminthiasis is accompanied by epileptic seizures and paralysis. It is also possible to infect the heart, in which myocarditis develops. In the absence of treatment for this type of infestation, anemia or hypergammaglobulinemia develops rapidly in patients.
Treatment of visceral toxocarosis
In the case when toxocar larvae hatched from eggs in large numbers have populated vital internal organs of a person, long-term therapy is needed to get rid of them, which should be carried out under the supervision of a specialist. Before the appointment of a therapeutic course, a special diagnosis is mandatory, which consists in examining the patient's blood for antibodies to the antigens of these helminths. The analysis of feces in the case of toxocarosis is ineffective, since it is impossible to detect the eggs and larvae of the parasite in it. Treatment of pathology is currently imperfect. The point here is that all medicines used for therapeutic purposes exert a destructive effect only on migratory larvae of toxocar. Encapsulated same remain viable. All therapeutic measures are performed using antinematous drugs:
- Mebendazole( Vermox) is used 2 times a day for at least 2 weeks. The dose of a single dose is 100 mg;
- Medamin is prescribed at 10 mg / kg body weight per day. Therapy is carried out by several repeated cycles of 10-14 days;
- The dosage of Albendazole is the same as that of Medamin, but unlike it, the drug is more toxic and can trigger the occurrence of adverse reactions such as abdominal pain, dizziness and nausea.
Due to the fact that all these drugs used to drive migratory larvae toxocar have high toxicity, and therapeutic courses with their long enough duration, they should be appointed only by a specialist and applied under his supervision. This will help to avoid side effects, and also make the process of destroying parasites more effective. As a supportive and auxiliary therapy for diseases caused by larvae toxocar diseases of internal organs, experts advise to use and recipes of traditional medicine. But their use is also allowed only after the diagnosis and consultation with a doctor.
