Today, helminthiasis is the most common parasitic disease, and its causative agents are helminths - two types of worms: flatworms and roundworms.A typical feature of helminth infections in humans is the nonspecificity of symptoms, i.e. the signs of the disease are consistent with many other pathologies.People are interested in the question: "How to determine whether parasites are present in the body, can I identify worms in the intestines at home?"
Signs of helminthiasis
The clinical course of the disease is divided into two stages - acute and chronic.The acute phase begins the moment the parasite enters the body and lasts from weeks to months.Symptoms in the acute phase appear due to body sensitivities - allergic reactions to the introduction of foreign substances (parasites), including:
- Increased body temperature.
- Violation of general health.
- Dyspeptic symptoms - diarrhea, constipation, nausea and vomiting.
- Joint and muscle pain.
- Pain in different parts of the abdomen.
- Apathy, loss of appetite, persistent fatigue.
- Rashes and itching appear on various parts of the body.
- Swollen lymph nodes.
The chronic phase is characterized by a variety of symptoms, depending on the species, location and reproduction intensity of the worm.It is characterized by increased gastrointestinal disorders, decreased immunity, frequent allergic reactions, nervousness, irritability, weight loss, and sleep disturbances.Patients often complain: "I'm constantly plagued by diarrhea and abdominal pain, and I feel exhausted"—symptoms that should prompt doctors to consider a helminth infection.
Even the most experienced doctors can't make a correct diagnosis based on symptoms alone, making it nearly impossible to detect worms at home.
Scatological methods for diagnosing the disease
All methods of diagnosing helminthiasis can be divided into two categories of studies:
- Direct - Allows doctors to directly detect the worm itself, its body fragments, and eggs or larvae.Examine the infected person's stool, urine, bile, sputum, or blood, as well as tissue and scraping material.
- Indirect – identification of pathological changes in the human body due to the presence of worms.The method allows doctors to examine blood images, the status of the immune system, the structure and functional disorders of affected organs.Among indirect methods, doctors often use X-rays and immunological diagnostic methods, as well as morphological blood tests.
A common direct method of diagnosing helminthiasis is fecal examination, which can be microscopic or macroscopic helminthoscopy.
Macroscopic helminthoscopy can examine the entire worm or its parts—segments, tapeworms, scolex.If the eggs of the parasite are not passed along with the stool, or their numbers are not sufficient for detection, for example, when identifying pork or cattle tapeworms, fragments of the worm can be seen in the stool, while in the case of pinworms, the entire pinworm can be seen.
You can detect parasites or their parts by visually examining your stool.Stool can also be examined using a magnifying glass or microscope if a differential diagnosis is required or if there is doubt about the reliability of the results.
Microworm microscopy gets its name from the use of a microscope.It allows you to identify parasite larvae or eggs in stool that is prepared in a special way on a glass slide before microscopic examination.This research is very reliable and allows doctors to differentiate between certain types of helminthiasis.
Special diagnostic methods for various forms of helminthiasis
You can find out if you have certain types of parasites in your body using specific diagnostic methods.The choice of method is made by the physician based on clinical data.
Diagnosis of taeniasis
Today, detecting pork or cattle tapeworms is quite difficult because fragments of the parasite are not usually passed out of the body in feces.The doctor may perform scrapings from the perianal area and microscopic helminthoscopy of stool.
Diagnosis of pinworm disease
How do you identify the parasite that causes pinworms in your body?The study was conducted in the morning without washing the perianal area.The simplest method is to use a wooden spatula or cotton swab dipped in glycerin solution for perianal scraping.The resulting material was transferred to a glass slide and subsequently examined under a microscope.
The modern method of scraping is to use adhesive tape (e.g. Scotch tape) to cut the material into 9-10 cm long strips.Apply the adhesive side of the tape to the perianal folds and smooth with a spatula, then carefully peel it off and transfer to the slide.Be careful when pasting to avoid air bubbles to prevent distortion of research results.
Microscopy of intestinal contents can identify not only intestinal parasites but also parasites located in the liver and gallbladder during opiodosis, fascioliasis, and other invasions.
Sputum examination to diagnose pulmonary helminthiasis
To identify parasites in the lungs and trachea, it is necessary to examine sputum, which is spread on a special plastic plate or glass and covered with another piece of glass.First, the material is inspected with the naked eye and only then with a microscope.
Study of Trichinellosis and Cysticercosis Muscle Tissue
To identify the larval form of Trichinella spiralis, a small piece of the gastrocnemius or biceps muscle is surgically removed, separated into individual fibers in the laboratory, and placed between two glass slides supplemented with glycerol.When looking at tissue samples under a microscope, Trichinella spiralis larvae are clearly visible.
The identification of cysticerci is also done after taking muscle or subcutaneous tissue.A small bubble of up to 2 cm in size can be seen with the naked eye.The bubble is crushed, its contents placed between glasses and viewed microscopically to determine the viability of the resulting parasite.
Diagnosis of schistosomiasis
To detect schistosomiasis, urine collected at noon was used as material.
In addition to urine, the material can also be feces, which undergo certain processing and microscopic examination.
Immunological methods for diagnosing helminthiasis
The most modern methods of identifying helminths today are various immunological studies.Similar diagnostic methods apply to helminthiasis, in which the pathogen is localized in the tissue itself or in an early stage of development and spreads throughout the body via the bloodstream.Skin and intradermal testing are considered informative methods that can reveal the presence of parasitic antibodies.
Direct immunological diagnostic methods include:
- Immunofluorescence antibody reaction (IFA) is used to detect cysticercosis and trichinellosis.
- Application of ring precipitation reaction in the diagnosis of trichinellosis.
- Latex agglutination is used to diagnose alveolar coccosis and hydatid disease.
- Immunoenzyme reactions diagnose echinococcosis, opioditis, trichinellosis, and alveolar coccosis.
Self-diagnosis of helminthiasis – is it possible?
Is it possible to test for the presence of parasites in the body at home without expert help?The answer to this question is unequivocal - no.All existing body computer diagnostic methods advertised on the Internet, as well as other uncertified and scientifically unproven methods, are unable to identify pathogens and make a correct diagnosis.Furthermore, refusing medical treatment with “non-traditional” diagnostic and treatment methods can lead to dangerous consequences, including patient disability and death.You should not ignore scientific advances and try to diagnose it yourself - it can be dangerous.In case of suspicious symptoms, it is best to consult a doctor.
