Level of igg antibodies to toxoplasma. Toxoplasmosis. Causes, symptoms, diagnosis and treatment of pathology. The process of deciphering the results

The carriers of the disease are felines, often ordinary domestic cats, which can infect a child, namely a girl, at an early age. The most striking manifestation of toxoplasmosis occurs during pregnancy. Until this moment, the gondi can calmly remain in the woman’s body without showing any signs of itself.

People also at risk include:

• with weakened immunity;
• patients with aggravated HIV infection;
• patients at oncology clinics after chemotherapy procedures;
• after an organ or bone marrow transplant.

The main areas affected by toxoplasmosis include the central nervous system and organs of vision. The disease manifests itself in the patient's feverish state, seizures, confusion, loss of coordination, blurred vision, and inflammation of the brain, or encephalitis.

Primary infection of a pregnant woman can lead to infection of the fetus through the placenta in up to 40% of all internal organs. This means that severe consequences are possible, and, as an option, fetal death. This is especially observed in the last trimester, says the head of the children's department of the Moscow clinic for children and adolescents SM-Doctor na Priorova, infectious disease specialist Tatyana Leonidovna Tarasova.

Analytical diagnostics for toxoplasmosis

In healthy and physically strong people, symptoms of the disease are completely absent. Only pronounced cases of immunosuppression bring the patient to the diagnostic room regarding the need to begin treatment.

The data of the enzyme immunoassay - ELISA for Ig G antibodies, their quantitative determination in blood serum, called quantitative analysis, are taken into account. Reference values, norm:

1. A negative indicator is less than 1.6 U/ml.
2. Positive – greater than or equal to 3.0 U/ml.
3. Doubtful – from 1.6 to 2.9 U/ml.

If the blood test gives indicators in the “doubtful” category, laboratory tests for antibodies are carried out two weeks later.

The essence of the enzyme immunoassay of blood serum for IgG, IgA and IgM antibodies lies in the field of determining the avidity of IgG to Toxoplasma.

If the number of IgG and IgM antibodies is detected in the titers, the norm is exceeded, or is in the “doubtful” category, a series of additional studies of protozoan DNA is carried out to identify the activity of the causative agent of the disease. Additionally, urine and blood tests are taken to determine the duration of the disease.

We should not forget that antibodies are produced by the human body in any case of an inflammatory process, both internal and in case of external infected injuries.

Immunoglobulin M, or Ig M

Depending on how long ago a person was infected with toxoplasma, antibodies also have their own age category. The designations G and M were introduced as recognition symbols to identify early and late Ig immunoglobulins formed during the development of the disease. Thus, Ig G antibodies belong to the category of late formations, and Ig M are early antibodies formed at the time of the initial infection of the human body by protozoa.

21 days after infection, the amount of IgM antibodies reaches its maximum quantitative levels in the blood plasma. Two months later they disappear without a trace. The presence of immunoglobulins of this type in the titer indicates that toxoplasmosis has caused the acute stage of the disease.

Immunoglobulin G, or Ig G

The body produces this type of antibody 72 hours later than IgM. Antibodies reach their maximum amount only 30 days after infection. This type of globulin does not disappear without a trace; on the contrary, Ig can be found throughout human life. It is he who tends to provide a person with immunity to one or another infectious disease that he has had.

When the results of tests for toxoplasmosis indicate the presence of antibodies of this category, a woman planning to conceive a child need not worry - even if her body is affected by protozoa, the fetus will no longer be in danger, states infectious disease specialist T.L. Tarasova.

Immunoglobulin A, or IgA

Any laboratory equipped with appropriate equipment can participate in these tests for toxoplasmosis. But the requirements for it are very strict. Despite the fact that the threshold norm may vary somewhat among all laboratories, Ig G avidity, or an assessment of the ability of an antibody of a given type and its ability to bind toxoplasma to neutralize it, is necessarily displayed on the appropriate blank. Thus, the analyzes indicate that Ig has a low or high degree of avidity. The higher the body's immune response, the higher the avidity of antibodies.

Norm of indicators and interpretation of the result

Indicators of laboratory tests for diagnosis of toxoplasmosis have their own standards - threshold, or reference values. A negative answer indicates a value below the threshold level, a positive answer indicates a value above the reference threshold.

Upon repeated examination, a jump in the amplitude of antibodies over 30% indicates the entry of the infectious process into the active stage, whereas such a phenomenon is observed during primary infection, when the increase in globulin G titers increases threefold in two weeks.

Interpretation of the ratios of immunoglobulins M and G in tests for toxoplasmosis:

In conclusion, it should be noted that more worthy scientific systems and methods for determining the presence of a disease do not yet exist today. Among the disadvantages, one can note the considerable cost of tests for toxoplasmosis, since the requirements for equipment are very high.

According to statistics, every third resident of Russia is infected with toxoplasmosis. At the same time, carriers of the disease often do not even realize that they are sick, because the infection may not manifest itself at all.

Since in most cases the course of the disease is asymptomatic, insufficient attention is paid to diagnostic and therapeutic methods of treatment. Meanwhile, the infection can lead to dangerous consequences, and sometimes even death.

But what does it mean if Toxoplasma gondii is detected in the blood? What is the norm and deviations of indicators, how do immunoglobulin IgG and IgM contribute to the diagnosis of infection and how can the disease be cured?

The most severe course is congenital toxoplasmosis. Therefore, it is especially important to diagnose this disease before pregnancy.

In general, the symptoms of toxoplasmosis in adults do not manifest themselves in any way. But the disease is most severe in children infected after intrauterine development and in patients with weakened immune systems.

The following forms of toxoplasmosis are distinguished:

1. spicy;
2. congenital;
3. ophthalmic;
4. CNS toxoplasmosis;
5. common.

The main signs of the congenital form of the disease in children include inflammation of the retina and small vessels, deafness, skin rashes, and jaundice.

Also, the child’s head may be disproportionate in size, and some children are lagging behind in psychomotor development.

As with any other infection, the human body reacts to toxoplasma by launching the immune system. As a result, it produces special antibodies, immunoglobulins of the IgM and IgG protein groups.

Having identified a pathogen (antigen), immune cells begin to produce antibodies to Toxoplasma. These helpers are called immunoglobulins of the ig g group. When they find the required antigen, they destroy its structure.

With the development of toxoplasmosis, the norm in the blood of igg to toxoplasma gondii is the detection of the IgG group of immunoglobulins on the third day after infection. Such antibodies persist throughout life, thanks to which the body is protected from reinvasion.

When infected with toxoplasmosis, other types of immunoglobulins of the IgM class also come into play to fight the disease. Igm toxoplasmosis is detected immediately after the pathogen enters the body.

However, IgM does not protect a person from re-infection.

After all, this type of immunoglobulin ceases to be produced after 2-4 weeks after infection.

Methods for diagnosing the disease

Often, to identify toxoplasmosis, an immunological and serological study is carried out, with the help of which antibodies to toxoplasma gondii are detected. Such techniques make it possible to detect not only the presence of antibodies, but also the time of onset of the development of the acute stage of the disease.

Special techniques are also used to identify the causative agent of the disease. For this purpose, microscopy and PCR diagnostics are used.

In addition, instrumental diagnostic methods can be used. However, such studies are carried out only in controversial situations and in cases where patients have serious complications. Along with this, the patient is prescribed an ultrasound and computer examination.

Sometimes a biological test is done to detect toxoplasma infection. It can also be used to find out if the body has class G antibodies to Toxoplasma.

The essence of the procedure is as follows: initially, a special allergen is injected under the skin. If swelling appears after a while, this means that the answer is positive.

However, for maximum reliability of the results, the reaction must be observed for at least 48 hours.

How to decipher the results?

When detecting antibodies to Tocho plasma in blood serum, the results may be different. So, if igg is positive and igm is negative, then this indicates that the person has strong immunity to toxoplasmosis for life.

Similar results can be found in 65% of the adult population. When igm is negative, igg is positive - this is a combination of antibodies in the blood of men, children and women planning pregnancy without carrying out any therapeutic measures.

If igg and toxoplasma antibodies are negative, and igm antibodies to toxoplasma are positive, then this indicates a primary infection with toxoplasmosis. Thus, there is a risk of intrauterine infection.

In this case, you need to donate urine and blood for the DNA of the pathogen for PCR diagnostics. Also, after 14 days, it is necessary to undergo an igg and igm toxoplasmosis test again, in which the igg value should not be positive.

When antibodies like class g to toxoplasma are positive and igm is also positive, then there is a possibility of primary infection. However, you need to know that igm can be positive from 90 days to two years after the illness.

If toxoplasmosis igm is negative, like igg, then this is a normal indicator indicating the absence of infection. It is noteworthy that women with such results, who are pregnant or are just planning a pregnancy, are in the risk category. Therefore, they need to be examined every trimester.

For this purpose, tests can be repeated at 22-24 weeks and immediately before birth. If seroconversion occurs, amniocentesis and PCR are performed to detect infection, and then therapy is carried out for the infected mother and child.

If igm is detected in the blood of a newborn above normal, the diagnosis can be confirmed, but only if a high level of this group of antibodies was also detected in the mother’s blood. In latent and chronic forms of infection in newborns, when the infection occurred in the first or second trimester of pregnancy, anti toxoplasma gondii igm may not be detected.

In this situation, infection is indicated by the dynamics of igg. But for reliability, it is necessary to study the igg indicators of the mother.

A newborn with lgg constantly becomes higher. In the absence of the disease, igg antibodies were not detected in the child's blood when the mother is seronegative, or their level decreases (elimination of maternal antibodies).

In the video in this article, experts will talk about the symptoms and treatment of toxoplasmosis.

The causes of the occurrence are always associated with contact with an infected person or animal. Cats are especially dangerous in terms of disease transmission. Toxoplasma can only multiply normally in the intestines of cats, excreted along with feces. For this reason, it is recommended to check domestic cats for toxoplasmosis, treat them promptly, and limit contact of pregnant women with them.

Testing for toxoplasma should be done regularly, especially in people planning to have a child. Toxoplasmosis IgM negative indicates the absence of infection, however it can quickly appear upon contact with an animal.

Infection, as a rule, occurs not through the animal’s fur, but through its feces (cleaning the toilet), through contaminated soil, that is, through dirty hands.

The most dangerous form of toxoplasmosis is congenital, in which case almost all systems and organs are affected.Main symptoms:

• Damage to the fetus in the womb. If infection occurs during or before pregnancy, miscarriages, premature birth, and intrauterine fetal death are possible. Congenital toxoplasmosis can also lead to damage to the central nervous system, retardation in physical and mental development, severe mental retardation, severe eye damage, and blindness.
• Fever. Acute acquired toxoplasmosis occurs as an acute infectious disease. Weakness, chills, high body temperature, and delirium often occur. At this stage, the disease is easily confused with mononucleosis or encephalitis.
• Inflammation of internal organs. Toxoplasma causes inflammation of many organs and tissues. You can see it. Due to liver inflammation, nausea and vomiting are often observed. If Toxoplasma affects the lungs, pneumonia may develop.
• There is also a form of carriage, when a person does not get sick himself, but can transmit the disease to others. In the chronic course of the disease, there are no pronounced symptoms, but a slight increase in body temperature, enlargement of the liver, and headaches may occur. Under unfavorable conditions (stress, other diseases), the chronic form becomes acute.

Methods for diagnosing and treating toxoplasmosis

The most effective method for diagnosing toxoplasmosis remains a serological blood test. The patient's blood is taken, which is then examined for the presence of the pathogen (enzyme-linked immunosorbent test).

As a rule, this diagnostic method is very informative and practically does not give erroneous results if the material is correctly collected and stored. When Toxoplasma enters the bloodstream, immunoglobulins begin to be produced after some time. The incubation period of Toxoplasma is short - a couple of weeks. During this time after infection, the body begins to form an immune response, releasing immunoglobulins into the blood. For the greatest reliability of the analysis, it can be repeated after 1-2 weeks.

Immunoglobulins in the blood (antibodies to a specific antigen) are classified and those that correspond to a reaction to Toxoplasma are isolated.

The presence of IgM immunoglobulins in the blood indicates the presence of infection.In addition to ELISA, toxoplasmosis can be detected using the polymerase chain reaction method. To do this, material is taken (blood or cerebrospinal fluid) and with the help of special reagents the DNA structure of the pathogen is restored, after which it is identified.

Diagnosis of toxoplasmosis is very important, since this disease must be distinguished from many similar infectious diseases.The doctor collects anamnesis before prescribing an examination, but it is impossible to identify toxoplasmosis only on the basis of symptoms; it has no characteristic signs.

More information about toxoplasmosis can be found in the video:

The acute form of toxoplasmosis usually resolves on its own. The immune system copes with the infection. If treatment is required, antimalarial and antibacterial drugs are usually prescribed. Complex drug therapy also includes multivitamin complexes, drugs to strengthen the immune system, and antihistamines.

Treatment is prescribed only if there are symptoms of the disease. During pregnancy, treatment is prescribed by a gynecologist depending on the duration and severity of the disease.If the treatment is successful, then after complete recovery the person develops stable, lifelong immunity to toxoplasma.

The doctor should decipher the test results. The result contains information for the doctor, so it cannot be used for independent diagnosis and self-medication.

Antibodies to Toxoplasma are called Anti-Toxo-IgM. They appear and are recognized in the blood 2 weeks after infection. These do not always disappear along with the infection; they can circulate in the blood for some time, so only the attending physician should interpret the result and prescribe further examination.

The test is quite reliable and informative. Errors are unlikely, but interpretation may be ambiguous. There are 3 options for the test result for toxoplasma:

• . A positive result indicates the presence of an acute infection of toxoplasmosis in the body, a recent infection, or congenital toxoplasmosis if the analysis is carried out in the first days of a newborn’s life. Antibodies can remain in the blood for up to a year even after complete recovery. It is worth remembering that for a pregnant woman, a positive test for toxoplasmosis is in any case an alarming signal. The pregnant woman is carefully observed, examined and the test for toxoplasma is repeated several times.
• . A negative test result indicates the absence of infection or the incubation period, when antibodies have not yet begun to be produced. A negative result usually indicates the absence of both acute and chronic infection. If there is any doubt that the infection could have occurred recently, the test should be repeated after 2 weeks. In a newborn, this analysis is interpreted unambiguously, since there is no incubation period for intrauterine infection, so a negative result clearly indicates the absence of infection.
• Doubtful. The result is considered questionable if the concentration of immunoglobulins of the IgM class in the blood is very low. In this case, no diagnosis is made, and it is recommended to repeat the test after a few weeks to confirm the result. A questionable result is often found at the very beginning of the disease.

Toxoplasmosis during pregnancy

It can be asymptomatic and heal on its own, which does not bring much inconvenience to the average person, but can become a real tragedy for a pregnant woman.

Often pregnant women refuse to get rid of their pets on the doctor’s recommendation and neglect stories about the consequences of toxoplasmosis. If a woman decides to keep the animal, she is warned about safety rules (do not touch or remove the potty, ask other family members to do this, use gloves and constantly wash your hands).

In the first trimester of pregnancy, the disease is milder and can be harmless for. During this period, the placenta has not yet formed, so the likelihood of Toxoplasma penetrating into the fetus is low. If the immune system copes with the pathogen, then there is a possibility of a favorable outcome.

In the second trimester, the danger is much higher. If the infection enters the blood, the risk of intrauterine infection of the fetus increases. The infection, entering the fetal blood, accumulates in the brain, affecting the central nervous system and optic nerves. There is a high probability that a child infected in utero with toxoplasmosis will be born with deformities incompatible with life. As a rule, such children with severe and deep lesions die either in the womb or some time after birth.

The third trimester is the most dangerous in terms of infection; here the probability of infection of the fetus through the mother’s blood reaches 60%.

If the infection occurred before the 3rd trimester, there is a chance that the child has already developed immunity and will be born healthy. However, this health may be apparent. There is a so-called latent form, when a child is born without abnormalities, but after a few weeks or months (and sometimes years) the consequences of the infection begin to appear.

Despite this, toxoplasmosis in a pregnant woman cannot be considered an indication for termination of pregnancy. The woman is carefully examined and undergoes various tests. If the amount of toxoplasma in the blood and amniotic fluid is large and constantly increasing, the risk of infection of the fetus is very high.Treatment of toxoplasmosis during pregnancy is still considered questionable, since the results are not always obvious, and harm from antibiotics is often more likely.

Test for toxoplasmosis

Currently, timely blood testing for toxoplasmosis allows not only to stabilize, but also to completely get rid of the infection. An analysis to detect toxoplasma is prescribed:

• women planning pregnancy or after conception;
• people with weakened immune systems;
• with enlarged lymph nodes for no apparent reason;
• HIV-infected patients;
• with pain of unknown origin, accompanied by fever, chills;
• with simultaneous enlargement of the spleen and liver;
• after an organ transplant or blood transfusion;
• if the previous analysis result was questionable.

Modern medicine offers several types of tests for toxoplasmosis. The most popular methods are:

• ELISA. The abbreviation stands for enzyme immunoassay, during which immunoglobulins IgG and IgM (G and M) are detected in the blood. These are antibodies that the body produces when the pathogen penetrates. During infection, immunoglobulins accumulate in different concentrations in the blood - this is called antibody titers.
• PCR. Polymer chain reaction is used if a blood test for toxoplasmosis gives a questionable result. The essence of the method is to identify the DNA and RNA molecules of the pathogen. For research, a sample of the carrier’s urine, blood, and saliva is taken.

What are antibodies to toxoplasma

Group M immunoglobulins

If toxoplasmosis is detected in the blood, immunoglobulin M (IgM) will be the first to respond to an acute infection. They are an indicator of humoral immunity, which protects the body from antigen proteins that are soluble in blood or other liquids. Class M antibodies to Toxoplasma appear in the blood already 2-3 days after the penetration of foreign microorganisms, reaching a maximum amount on 21 days. 2 months after infection, the amount of immunoglobulin IgM decreases to almost zero.

Anti toxoplasma gondii igg

Class G antibodies to Toxoplasma after infection in the carrier’s blood appear later (after several weeks), but remain longer (up to 2 years). The presence of Anti toxoplasma gondii igg in the analysis indicates that the body has previously encountered this infection, and it recognized it. If G antibodies are detected, we can also talk about the chronic course of the infection. At this stage, treatment for toxoplasmosis is not required. A certain amount of IgG immunoglobulin in the blood remains throughout a person’s life, even after recovery.

What is the difference between IgG and IgM antibodies?

M antibodies detected in the blood tell the doctor about the patient's recent infection with toxoplasmosis. The amount of IgM is only 10% of all immunoglobulins. If it is elevated, this indicates the presence of infection and inflammation in the body. If IgM antibody levels are low, this indicates immunodeficiency. Anti Toxoplasma Gondii IgG immunoglobulins are the most common. Their number makes up 80% of the total antibody levels. Due to their great functionality, antibodies to Toxoplasma IgG provide a positive effect on the body:

• strengthen protective forces;
• neutralize toxic substances;
• contribute to the formation of immunity in the fetus during pregnancy.

Decoding indicators

A blood test for antibodies is done using ELISA (enzyme-linked immunosorbent assay). It has threshold (maximum permissible) and reference (average) values. If the marker value is below the pore titer, then the analysis result is negative, and if it is higher, it is positive. Each laboratory has its own standards for IgG immunoglobulin levels. Decoding of indicators in various combinations:

Interpretation of enzyme immunoassay based on avidity indicators

To determine the phase of development and duration of the disease, an additional study of immunoglobulins is sometimes performed. As a result of laboratory analysis of blood serum, an avidity index for Toxoplasma is obtained. Studying antibodies in this way provides a quick opportunity to find out the strength of their connection with a foreign agent. The longer the infection remains in the body, the higher the avidity value.

Antibodies to toxoplasmosis during pregnancy

If a woman is diagnosed with IgG positive toxoplasmosis during pregnancy in the absence of IgM antibodies, this means that in the past she had contact with this infection, so now she has a strong immunity that will protect against secondary infection. This result shows that class G immunoglobulins will also protect the child in the womb, because they easily penetrate the placental barrier.

If the expectant mother has positive IgM in the absence of IgG, then this is a dangerous factor for the unborn child. If the primary infection with Toxoplasma occurs in the 12th week of pregnancy, then the risk of developing congenital anomalies in the fetus increases, because during this period the embryo develops kidneys, liver and other parts of the body. In some cases, pathological changes in the child’s body lead to his death at birth.

The progression of toxoplasma in a pregnant woman before the 30th week can cause damage to the baby’s visual organs and/or brain. An infection acquired by the expectant mother at this stage of pregnancy can lead to the following pathologies in the child:

• hydrocephalus (water on the brain);
• complete blindness;
• underdevelopment of cataracts and brain.

In severe cases of infection, the child may experience damage to the liver, spleen, hematopoietic system, and digestive organs. If Toxoplasma progresses or remains untreated, a pregnant woman may have a miscarriage. If the infection occurs in the last stages, then there is a high risk of premature birth. During breastfeeding, if the mother does not have an active form of toxoplasmosis, infection through breast milk is excluded.

More recently, the diagnosis of toxoplasmosis during pregnancy was the main indication for its termination. Today, a woman with this pathology is under individual monitoring by doctors and needs additional clinical studies. The main indications for testing for toxoplasmosis in pregnant women:

• complete lack of appetite;
• body aches;
• general weakness;
• sleep disturbance;
• intestinal disorder;
• increase in body temperature up to 38 ° C;
• enlarged liver;
• increased sweating;
• sore throat;
• enlarged lymph nodes.

What to do if IgM is positive

Treatment of toxoplasma in pregnant women begins at 12–16 weeks. If positive antibodies to Toxoplasma IgM are detected in the absence of IgG (primary infection) at an early stage, the woman is offered an abortion. This is due to the fact that to get rid of toxoplasma it is necessary to take antibiotics, which will negatively affect the development of the fetus.

In the absence of intrauterine infection (according to the results of PCR of amniotic fluid), doctors prescribe macrolide antibacterial drugs: Spiramycin, Macropen. They are able to accumulate in the placenta, preventing the vertical transmission of toxoplasma.

• Antiviral. After administration, viruses are integrated into DNA, suppressing its synthesis (Ganciclovir, Panavir, Foscarnet).
• Immunoglobulins. Capable of forming the immunity of a pregnant woman and child (Pentaglobin, Octagam).
• Interferons. They inhibit the active reproduction of viral particles and limit their movement (Viferon, Realdiron).

The basis for the prevention of Toxoplasma infection is the implementation of hygiene standards, the choice of safe food preparation methods, and compliance with the rules for keeping pets. To reduce the risk of infection you should:

• wash your hands before and after preparing food;
• wear gloves while cultivating the soil;
• do not consume raw goat milk;
• avoid eating undercooked or raw meat;
• Always wash vegetables, fruits and berries before eating;
• Avoid direct contact with cat feces (change the litter box using gloves).
