Today, helminths are the most common parasitic diseases, the causative agents of which are helminths - two types of worms: flat and round.A characteristic feature of helminth infections in the human body is non-specific symptoms, that is, signs of the disease are consistent with many other pathologies.People are interested in the question: "How to determine the presence of parasites in the body and is it possible to recognize helminths in the intestines at home?"
Signs of helminth disease
The clinical course of the disease is divided into two stages - acute and chronic.The acute phase begins from the moment the helminth enters the human body and lasts from several weeks to several months.Symptoms of the acute phase develop as a result of the body's sensitivity - an allergic reaction in response to the invasion of a foreign agent (parasite) and include:
- Body temperature increases.
- General health violations.
- Indigestion symptoms - diarrhea, constipation, nausea and vomiting.
- Pain in joints and muscles.
- Abdominal pain in many different locations.
- Lethargy, loss of appetite, constant fatigue.
- Skin rash, itching of various parts of the body.
- Enlarged lymph nodes.
The chronic phase is characterized by a variety of symptoms, depending on the helminth species, location and intensity of reproduction.Characterized by increasing disturbances in the functioning of the gastrointestinal tract, weakened immunity, frequent allergic reactions, stress, irritability, weight loss and sleep disorders.Patients often complain: “I often have diarrhea and stomach pain, I feel exhausted” - such symptoms make doctors think about helminth infection.
Even the most experienced doctor cannot make an accurate diagnosis based on symptoms alone, so it is difficult to detect worms at home.
Methods of diagnosing diseases
All methods of diagnosing helminthiasis can be divided into two types of studies:
- Direct - allows doctors to directly detect the helminth, its body fragments, as well as eggs or larvae.The infected person's stool, urine, bile, sputum or blood, as well as tissue and debris are examined.
- Indirect – determines pathological changes in the human body as a result of the presence of helminths.This method allows doctors to examine blood images, the state of the immune system, and structural and functional disorders of affected organs.Among indirect methods, doctors often use X-ray and immunological diagnostic methods as well as morphological blood tests.
A common direct method for diagnosing helminthiasis is pathological examination, which can include microscopic and macroscopic helminthoscopy.
Diagnosis by macroscopic helminthoscopy helps detect the entire helminth or its parts - segments, cestodes, scolex.Such a study is prescribed by the doctor if the eggs of the parasite are not excreted with the feces or their quantity is insufficient for detection, for example, when determining pork or beef tapeworms, helminth segments can be seen in the feces, and in case of pinworm disease, entire pinworms can be seen.
You can detect parasites or their parts by visually examining the stool.If it is necessary to differentiate the diagnosis or there is doubt about the reliability of the results, the stool will be additionally examined with a magnifying glass or microscope.
Microscopic examination is called due to the use of a microscope.It allows you to identify parasite larvae or eggs in feces, prepared in a special way on glass slides before examination under a microscope.This research is quite reliable and allows doctors to distinguish several types of helminths from each other.
Special diagnostic methods for different forms of helminthiasis
You can find out if your body has certain types of parasites using specific diagnostic methods.The choice of method is made by the doctor based on clinical data.
Diagnosis of taeniadoses
Detecting pork or beef tapeworms is quite difficult today, because parasite segments are often not eliminated from the body through feces.The doctor may use the method of scraping the perianal area and examining the stool with helminthoscopy.
Diagnosis of enterobosis
How to identify parasites in the body that cause intestinal diseases?The study was performed in the morning, without washing the perianal area.The simplest method is to scrape around the anus with a wooden spoon or cotton swab dipped in a glycerin solution.The resulting material is transferred to a glass slide, then examined under a microscope.
A modern type of scraping is to take the material with tape, for example, tape, cut into strips 9-10 cm long.The tape is applied with the adhesive side to the perianal folds and flattened with a spatula, then carefully peeled off and transferred to a glass slide.It is important to paste carefully, without air bubbles, to avoid distorting the research results.
Microscopy of intestinal contents helps identify not only intestinal parasites but also those localized to the liver and gallbladder in opisthorchiasis, fasciolosis, and other invasions.
Sputum testing to diagnose pulmonary helminths
To identify parasites localized in the lungs and trachea, sputum is examined, smeared on a special plastic or glass plate and covered with another glass plate on top.First of all, the material is examined with the naked eye, and only then a microscope is used.
Research on muscle tissue in trichinosis and tapeworms
To identify the larval forms of Trichinella, a small piece of the gastrocnemius or biceps muscle is surgically removed, which is divided into individual fibers in the laboratory and placed between two glass slides supplemented with glycerol.When observing tissue samples under a microscope, Trichinella larvae are clearly seen.
Identification of hydatid cysts is also done after removing muscle tissue or subcutaneous tissue.With the naked eye, you can see a small bubble up to 2 cm in size.This bubble is crushed, its contents are placed between glasses and observed microscopically to determine the viability of the resulting parasites.
Diagnosis of schistosomiasis
To detect schistosomiasis, urine collected in the middle of the day was used as material.
In addition to urine, the material can also be feces, which must undergo certain processing and microscopic examination.
Immunological methods for diagnosing helminths
The most modern methods for identifying helminths today are various immunological studies.Similar diagnostic methods are suitable for helminths, the causative agent of which is located in the tissues or is in the initial stages of development and spreads throughout the human body through the bloodstream.Skin and intradermal testing are considered an informative method that can reveal the presence of parasite antibodies.
Direct immunodiagnostic methods include:
- Immunofluorescent antibody (IFA) reaction to detect helminthiasis and trichinosis.
- Ring precipitation reaction in the diagnosis of trichinosis.
- Latex agglutination reaction for diagnosing alveolar disease and echinococcosis.
- Immune response in the diagnosis of echinococcosis, opisthorchiasis, trichinosis and alveolococcosis.
Self-diagnosis of helminths – is it possible?
Is it possible to check for the presence of parasites in the body at home without the help of a specialist?The answer to this question is unequivocal - no.All existing methods of computerized diagnosis of the body, advertised on the Internet, as well as other uncertified and scientifically unfounded methods, are unable to identify the pathogen and provide an accurate diagnosis.Additionally, withholding medical care in favor of “non-traditional” methods of diagnosis and treatment can lead to dangerous consequences, including patient disability and death.You should not ignore scientific advances and try to diagnose yourself - this can be dangerous.At the first suspicious symptoms, it is better to consult a doctor.
