There are 4.5 billion people recorded worldwide as suffering from parasitic infections (infestations).In addition, the number of people infected with helminths (worms) is constantly increasing.
Causes of helminthiasis infection
It is not difficult to introduce worms into your body.Here are just a few causes of infection familiar to everyone from childhood:
- Insufficient hygiene.The desire to eat unwashed fruits and vegetables, not to wear gloves while working in the garden and not to worry about hygiene procedures leads to infection with a variety of helminths.
- Addiction to street fast food.It is no secret that sellers of such foods do not always undergo medical examinations and often neglect basic hygiene.And their products are not stored in the best conditions.Another group at risk are lovers of street whites and pastries.
- Love for exotic cuisines, including dishes based on raw fish and shellfish containing parasites.It is sushi and roll enthusiasts who are responsible for the increased incidence of flukes, tapeworms, roundworms, roundworms and worms.
- Nothe ability to adequately protect oneself from infections while resting.Love for the "Turkish coasts" has led to an increase in cases of infection with exotic helminthiasis: schistosomiasis, hookworm and dracunculiasis.After walking barefoot on an overseas beach, you can bring back from your trip not only pleasant impressions, but also dangerous worms.
- Pet infectionwho often sleep with their owners.Those who like to “kiss” their pet run the risk of contracting parasites.
What parasites live in the human body
If an adult had the opportunity to look into his body, he would be horrified:
- Nematodes –pinworms, roundworms, whipworms, roundworms, toxocara, trichinella.Large helminths gather into huge balls, blocking the intestinal lumen and causing obstruction, requiring surgical treatment.Doctors remove an incredible amount of parasites from the intestines of these people during surgery.
- Tapewormsappear among those who love to taste rare meat and raw fish.Causes digestive problems, anemia, allergies.Children experience seizure-like convulsions.The most dangerous helminth of this group is echinococcus, the larvae of which form huge cysts in the human body.When they rupture, the parasites disperse throughout the body.The infection can be fatal.
- Strokes of luck– Flukes, flukes and flukes are dangerous parasites that suck blood from the vessels of the liver, pancreas, intestines and bladder.
- Protozoa– leishmania, amoeba, lamblia, etc.Although these tiny parasites are only visible under a microscope, they can cause dangerous complications, including intestinal perforation and liver abscesses, which are fatal.
By what signs can one suspect the presence of “strangers”: if your stomach hurts, it means that someone lives there
Signs of the presence of helminths:
- Abdominal pain- the most common sign of helminth infection.It can be constant, periodic and affect certain areas of the abdomen.Pain in the right hypochondrium during helminthiasis indicates damage to the liver and gallbladder by worms.
- Digestive disorders– diarrhea, constipation, irregular bowel movements.Sometimes patients see crawling segments of worms or even entire parasites in their feces.Reduced food absorption and gastrointestinal dysfunction lead to weight loss.
- Anemia.The worms suck blood from the body and interfere with the digestion of food.The human host does not feed itself, but the worms.Patients complain of weakness, fatigue, loss of strength and dizziness.
- Damage to the urinary tractcaused by parasites that live in the kidneys and bladder.Patients complain of lower back pain and swelling.Sometimes traces of blood are visible in the urine.
- Slow chronic vaginitis.Roundworms and pinworms crawl from the anus into the genital tract, causing vaginal dysbiosis and provoking the development of thrush.Women are treated for itching and discharge, without realizing that parasites are the problem.
- Skin manifestations.Worm infection poisons the body and suppresses the immune system, causing allergies.The rashes vary from small blisters to large focal areas.
- Inflammation of the mucosaand itching in the anal area caused by irritation from crawling worms.
- General worsening of health.Weak immunity, poor digestion and anemia weaken the body, which cannot resist infections.A person is haunted by constant colds, acute respiratory infections and acute respiratory viral infections.
Because ultrasound is more effective than traditional tests for worms and other parasites
Giving stool or scraping does not always reveal worms.The fact is that parasites have a certain development cycle and do not always lay eggs.There is a whole group of extraintestinal helminthiases, in which worms live outside the intestine.In this case, a stool test will not provide any information.
Ultrasound of the abdominal cavity shows changes characteristic of the presence of parasites in the liver and pancreas.It is harmless, non-traumatic and can be used many times.
If the doctor does not find live helminths and 100% signs of their presence on the ultrasound, he will suspect an infection and prescribe further examination.It is also helpful to have an ultrasound if tests for worms come back positive.The study will show where the parasites are hiding.
Signs of helminthiasis determined by ultrasound of the abdominal cavity: semi-living organs and live worms
When examining the gastrointestinal tract using modern 3D and 4D devices, doctors often see live parasites in the intestine.If helminths are not detected, their presence can be suspected by an enlarged pancreas, compacted in the head area.The spleen is also too large.
The liver is enlarged due to parasitic infections from flukes, flukes, and flukes.Reveals areas of dystrophy that impede the functioning of the organ.
The gallbladder also suffers.Patients experience stagnation of bile, causing pain in the right hypochondrium.Sometimes bladder function is so impaired that the organ is not detected at all by ultrasound.
The presence of parasites leads to the formation of abscesses - purulent liver lesions that are life-threatening.In 85% of cases, abscesses form in a lobe of the liver.Other departments suffer less frequently.Purulent lesions are characteristic of hepatic amoebiasis - infection with a protozoan - an amoeba that enters the liver region from the intestine.
Significant changes in the liver are observed during echinococcosis, a parasitic disease in which cavities filled with helminth larvae form inside the organ.Ultrasound shows round formations with clear boundaries.These are cysts that contain parasites.Over time, calcium is deposited around echinococcal lesions.Such formations have a dense structure, so on ultrasound they seem lighter than surrounding tissues.
With prolonged infection, large cysts with partitions are formed, similar to wheel spokes or large honeycombs.There is destruction of the bile ducts.Doppler examination reveals a disturbance in blood flow.
For lovers of Japanese cuisine.Parasites - as a gift
A wide variety of parasites are found among Asian exotic enthusiasts, but the most common is opisthorchiasis, the Chinese fluke infection.The source of helminths is unprocessed fish containing parasites.
At the onset of the disease, ultrasound reveals eosinophilic infiltrates in the liver and gallbladder: dense formations with clear boundaries.If the fight against helminths is postponed until better times, foci of dead cells will appear in these organs, resembling spotty areas, and the liver ducts will lose their elasticity.The situation can lead to the development of liver failure.
If the urinary tract becomes a victim of parasites
Echinococcus affects not only the liver, but also the kidneys.When the parasite enters the kidney tissue, a single-chambered cyst (bladder) containing the larvae forms.Gradually increasing in size, the hydatid cyst destroys the organ.Large parasitic cysts adhere to the liver, spleen, and intestines.
Schistosomiasis is contracted by those who enjoy walking barefoot along the warm beaches of overseas countries.The larvae of the parasite enter the bloodstream through the skin and are then transported to the bladder along with the blood.Having settled there, they cause the appearance of compactions - infiltrates that appear in response to irritation of the walls of the bladder.As the infection spreads, the kidneys are affected.
Blood test with enzyme immunoassay: we bring helminths to clean water
This test can detect infection with one or more types of parasites.It is carried out due to the presence of nematodes, toxocara, trichinella, opisthorchis trematodes, echinococci, Chinese trematodes, etc.
The principle of the test is based on the body's immune response to the presence of helminths.Infection with worms causes the production of protein antibodies, which are detected during the analysis.Since each parasite causes the formation of a certain immunoglobulin, the test results show which helminths are found in the human body.
The assay reacts to all forms of parasites: eggs, larvae, adult worms.Accuracy is over 90%.The examination shows not only the presence of the infection, but also its degree.
After treatment, the test is repeated.A positive result can be observed for some time after the death of the parasites.The immunoglobulin concentration will gradually decrease over several more months.Then the analysis will become “clean”.For the study, blood is taken from a vein on an empty stomach in a volume of 3-5 ml.The analysis is performed twice.
Ultrasound and immunoglobulin tests can identify helminthiases and begin treatment.Thanks to their use, the number of cases of incorrect diagnoses leading to complications has decreased.The main thing is to promptly consult a doctor if you suspect a helminth infestation.
