Cmv igg treatment. What does positive IgG for cytomegalovirus mean? How does the cytomegalovirus infection work?

(CMV) is one of the causative agents of herpes infection. Detection of immunoglobulins (Ig) in the blood allows you to determine the stage of development of the disease, the severity of the infectious process and the state of immunity. The class of immunoglobulins G indicates immunological memory - the penetration of cytomegalovirus into the body, the carriage of infection, the formation of stable immunity. For the correct diagnosis of the disease, it is carried out in parallel with the indicators of the concentration in the blood of Ig M and the avidity index. Next, we will consider in detail what this means - cytomegalovirus Ig G is positive.

When infectious agents, including viruses, enter the body, the immune system produces protective protein substances - antibodies or immunoglobulins. They bind to pathogenic agents, block their reproduction, cause death, and remove them from the body. For each bacterium or virus, specific immunoglobulins are synthesized that are active against only these pathogens. CMV, when it enters the body, penetrates the cells of the nervous and immune systems, the cells of the salivary glands and remains in them in a latent state. This is the carrier phase of the virus. With a significant decrease in immunity, an exacerbation of the infection occurs.

Antibodies come in different classes: A, M, D, E, G. When cytomegalovirus infection is detected, immunoglobulins of class M and G (Ig M, Ig G) are of diagnostic value.

Antibodies come in different classes: A, M, D, E, G. When cytomegalovirus infection is detected, immunoglobulins of class M and G (Ig M, Ig G) are of diagnostic value. Immunoglobulins M are produced from the first days of infection penetration into the body and during exacerbation of the disease. Ig M have large sizes of protein molecules, neutralize viruses, lead to recovery. Ig G are smaller in size, are synthesized 7-14 days after the onset of the disease and are produced in small quantities throughout a person's life. These antibodies are an indicator of immunological memory for CMV and keep the virus under control, preventing it from multiplying and infecting new host cells. With re-infection or exacerbation of the infection, they are involved in the rapid neutralization of viruses.

Evaluation of the results of the analysis for the detection of class G immunoglobulins

Antibodies in the blood are detected using immunological laboratory diagnostics - enzyme immunoassay (ELISA). To determine the stage of the disease and the level of immunity to cytomegalovirus, the presence of Ig G, Ig M, in the blood or other biological fluid is assessed. The analysis only for the content of class G immunoglobulins does not have sufficient diagnostic value and is not prescribed separately.

The structure of the immunoglobulin G (Ig G) molecule.

Possible results of ELISA for the determination of antibodies to CMV.

1. Ig M - negative, Ig G - negative. It means that the body has never encountered, there is no stable immunity, there is a high probability of infection with CMV.
2. Ig M is positive, Ig G is negative. It means that the primary penetration of the infection into the body, the acute phase of the disease, stable immunity has not yet been developed.
3. Ig M - positive, Ig G - positive. It means an exacerbation of the disease against the background of a chronic course or carriage, which is associated with a sharp inhibition of the body's defenses.
4. Ig M - negative, Ig G - positive. It means the phase of recovery after a primary infection or exacerbation of the disease, the period of the chronic course of the disease, carriage, a strong immunity to CMV has been developed.

For the correct interpretation of the stage of the disease, the presence of Ig G and Ig M in the blood is carried out along with the determination of the value of the Ig G avidity index - the ability of antibodies to bind to the virus. At the beginning of the disease, this indicator is low, as the infectious process develops, the avidity index increases.

Evaluation of the results of the Ig G avidity index.

1. Avidity index less than 50% - low ability to bind class G immunoglobulins with cytomegalovirus, early phase of the acute period of the disease.
2. An avidity index of 50-60% is a questionable result, the analysis must be repeated after 10-14 days.
3. Avidity index over 60% - high ability to bind class G immunoglobulins to the virus, late phase of the acute period, recovery, carriage, chronic course of the disease.
4. Avidity index 0% - there is no cytomegalovirus infection in the body.

When determining Ig G in blood or other biological fluid, the avidity index cannot be equal to 0%.

The role of the determination of class G immunoglobulins

Primary infection and carriage of CMV at a normal level of immunity is asymptomatic without appreciable harm to health. Sometimes, during infection and exacerbation of the infection, a mononucleosis syndrome occurs, the clinical signs of which are similar to the manifestations of a cold: weakness, headache, subfebrile temperature (37-37.6), tonsillitis, enlargement of regional lymph nodes. In most cases, cytomegalovirus infection goes unnoticed, diagnostics for the detection of antibodies is not carried out.

For a contingent of people who are at risk for developing severe forms of the disease, the detection of Ig G in the blood is of great importance. In these patients, CMV affects the brain (meningoencephalitis), liver (hepatitis), kidneys (nephritis), eyes (retinitis), lungs (pneumonia), which can be fatal. During pregnancy, infection or exacerbation of infection leads to intrauterine death of the fetus, the formation of malformations, prenatal cytomegalovirus infection. An assessment of the level of class G antibodies is carried out to prescribe antiviral therapy and determine the prognosis of the disease.

At-risk groups:

• congenital immunodeficiencies;
• acquired immunodeficiencies;
• artificial immunodeficiencies (glucocorticoids, chemotherapy, radiation therapy);
• transplantation of internal organs;
• severe chronic diseases;
• intrauterine development of the fetus.

An analysis for the determination of Ig G and Ig M in blood or other biological fluids is prescribed regularly for early detection of primary infection and exacerbation of the disease.

Risk group - patients with immunodeficiency conditions

A sharp decrease in the body's defenses in immunodeficiencies leads to a decrease in the synthesis of class G immunoglobulins, which occurs constantly after the primary infection with CMV. Against this background, the virus passes from a latent ("sleeping") state into an active phase of life - it destroys the cells of the salivary glands, the nervous and immune systems, multiplies, affects the tissues of the brain and internal organs. When the immune system is depressed, severe forms of the disease develop.

To control the activity of cytomegalovirus in the body, patients with immunodeficiency conditions are prescribed routine blood tests for Ig G, Ig G, Ig M avidity index. Patients receiving immunosuppressive therapy - cancer treatment, autoimmune diseases, after organ transplantation, immunological diagnostics are carried out for timely appointment of antiviral drugs and prevention of disease progression.

Risk group - fetus during fetal development

At the stage of pregnancy planning, in the first and second half of gestation, a woman needs to take a blood test for the content of antibodies to CMV. Assessment of immunological memory to cytomegalovirus infection determines the risks of intrauterine infection and fetal death.

The main risk group is people with immunodeficiency conditions (HIV, AIDS, the effects of chemotherapy).

1. Ig G is positive, avidity index is more than 60%, Ig M is negative. Means that . The mother's body has developed immunity to cytomegalovirus infection. Exacerbation of the disease is unlikely, in most cases it is safe for the fetus.
2. Ig G is negative, avidity index is 0%, Ig M is negative. Means that there is no immunity to CMV in the mother's body. There is a risk of primary infection with cytomegalovirus infection during pregnancy. A woman needs to adhere to preventive measures to prevent infection and donate blood for antibodies to CMV.
3. Ig G - positive, avidity index over 60%, Ig M - positive. It means that against the background of a decrease in immunity, an exacerbation of the infection occurred. It is necessary to monitor the development of the disease and the condition of the fetus. In most cases, the intrauterine development of the child proceeds normally, since the mother has an immunological memory for cytomegalovirus.
4. Ig G is negative, avidity index is less than 50%, Ig M is positive. The result of the analysis means a high risk of intrauterine infection of the fetus and the absence of immunity in the mother. When infected in the first 12 weeks of pregnancy, malformations are formed or intrauterine death of the child occurs. In the second half of pregnancy, prenatal cytomegalovirus infection of the fetus develops. Depending on the severity of the infection, observation, antiviral therapy, medical abortion, or premature delivery are prescribed.

The evaluation of the diagnostic results for the detection of antibodies to CMV is carried out by a doctor. When establishing the severity of the course of the disease and for prescribing therapy, the clinical picture, anamnesis of the disease, the presence of concomitant pathology, and the results of other diagnostic methods are taken into account.

The presence of class G immunoglobulins in the blood and other biological fluids indicates a past cytomegalovirus infection and the formation of stable immunity. In people with a healthy immune system, this is an indicator of protection against re-infection and exacerbation of the disease.

More on this topic:

What it is? Cytomegalovirus is a genus of viruses in the herpesvirus family. This virus is quite common, today cytomegalovirus antibodies can be found in about 10-15% of adolescents, and in 40% of adults. Below, we will give a full description of this disease, as well as consider the causes, symptoms and treatments for cytomegalovirus.

Causes and ways of infection with cytomegalovirus

Cytomegalovirus (from lat. Cytomegalovirus) is actually a relative of herpes vulgaris, because it belongs to the group of herpesviruses, which includes, in addition to herpes and cytomegalovirus, also two diseases such as infectious mononucleosis and.

The presence of cytomegalovirus is noted in blood, semen, urine, vaginal mucus, and also in tears, which determines the possibility of infection by it through close contact with these types of biological fluids.

How does infection occur? Cytomegalovirus infection can occur:

• when using contaminated items,
• by blood transfusion and even by airborne droplets,
• as well as during sexual contact,
• during childbirth and pregnancy.

The virus is also found in blood, saliva, cervical secretions, semen, and breast milk.

If a person has already become infected with cytomegalovirus, then he becomes its carrier for life.

Unfortunately, it is not possible to recognize the presence of cytomegalovirus immediately - this disease has an incubation period that can last up to 60 days. During this period, the disease may not manifest itself in any way, but after that, there will definitely be an unexpected and sharp outbreak, which in most cases can be provoked by stress, hypothermia or a general decrease in the immune system.

Once in the blood, cytomegalovirus causes a pronounced immune reaction, manifested in the production of protective protein antibodies - immunoglobulins M and G (IgM and IgG) and an antiviral cellular reaction - the formation of CD 4 and CD 8 lymphocytes.

People who have a normal immune system may be infected with cytomegalovirus and not know about it, as the immune system will keep the virus suppressed, therefore, the disease will be asymptomatic, without causing harm. In rare cases, in people with normal immunity, cytomegalovirus can cause a mononucleosis-like syndrome.

In people with weak or weakened immunity (HIV-infected, cancer patients, etc.), cytomegalovirus causes serious illness, damage occurs:

• eye,
• lungs
• brain and digestive system,
• which eventually leads to death.

Cytomegalovirus is the most dangerous in only two cases. These are people with weakened immune systems and children who were infected while the fetus was in the womb of a mother who contracted the virus during pregnancy.

Symptoms of cytomegalovirus in women

In women, the symptoms of cytomegalovirus will appear depending on the form of the disease. The disease begins with an incubation period of 20-60 days. At this time, the pathogen actively multiplies in the cells, and there are no signs of the disease.

If the woman's immunity is not weakened, then no symptoms of the disease will be observed. In some cases, a woman may be concerned about:

• flu-like symptoms
• a slight increase in temperature up to 37.1 ° C,
• weakness,
• slight discomfort.

Signs in men

Stopping on the symptoms of cytomegalovirus in men, the following manifestations can be distinguished:

• temperature increase;
• chills;
• headache;
• swelling of the mucous membranes and nose;
• enlarged lymph nodes;
• runny nose;
• skin rash;
• inflammatory diseases that occur in the joints.

As you can see, the listed manifestations are similar to the manifestations observed in acute respiratory infections and acute respiratory viral infections. Meanwhile, it is important to take into account that the symptoms of the disease occur only after 1-2 months from the moment of infection, that is, after the end of the incubation period.

Diagnostics

We found out what cytomegalovirus is, and now let's find out how the disease is diagnosed. To diagnose sexually transmitted infections (STIs), methods are used based on the detection of the virus that causes the disease in the body. However, this disease is different. After all, it can be detected with the help of a special study of blood, urine, saliva, smears, semen and scrapings, which are taken from the genital organs during the primary infection or during an exacerbation of the infection.

1. For the purpose of diagnosis, a laboratory determination of specific antibodies to cytomegalovirus, immunoglobulins M and G, is carried out in the blood. The presence of immunoglobulins M may indicate a primary infection with cytomegalovirus or a reactivation of a chronic cytomegalovirus infection. Determination of high titers of IgM in pregnant women may threaten infection of the fetus. An increase in IgM is detected in the blood 4-7 weeks after infection with cytomegalovirus and is observed for 16-20 weeks.
2. An increase in immunoglobulins G develops during the period of attenuation of the activity of cytomegalovirus infection. Their presence in the blood indicates the presence of cytomegalovirus in the body, but does not reflect the activity of the infectious process.
3. To determine the DNA of cytomegalovirus in blood cells and mucous membranes (in the materials of scrapings from the urethra and cervical canal, in sputum, saliva, etc.), the method of PCR diagnostics (polymerase chain reaction) is used. Especially informative is the quantitative PCR, which gives an idea of ​​the activity of cytomegalovirus and the infectious process it causes.
4. The diagnosis of cytomegalovirus infection is based on the isolation of cytomegalovirus in clinical material or a fourfold increase in antibody titer.

It is worth noting that it is advisable to take tests for cytomegalovirus for women who are planning a pregnancy. It is also necessary to pass a similar analysis to those people who very often have a cold, since a cold can be a manifestation of this infection.

It is necessary to treat cytomegalovirus infection in a complex way, therapeutic therapy should include drugs that are directly aimed at combating the virus, at the same time, these drugs should increase the protective functions of the body and strengthen the immune system. At present, no such remedy has yet been invented that could completely cure cytomegalovirus, it remains in the body forever.

The main goal of the treatment of cytomegalovirus is the suppression of its activity.. People who are carriers of this virus need to adhere to a healthy lifestyle, eat well, and consume the amount of vitamins necessary for the body.

Due to the fact that in the vast majority of cases the body itself is able to cope with cytomegalovirus, the treatment of the infection associated with it is most often limited to easing the symptoms and reducing the suffering of the patient.

To reduce the temperature characteristic of almost all forms of cytomegalovirus infection, use the usual Paracetamol. Aspirin is not recommended due to possible side effects associated with the viral nature of the disease.

It is also very important for carriers of this disease to lead a normal and proper lifestyle that provides a person with the right amount of fresh air, a balanced diet, movement and all the factors that strengthen the immune system.

In addition, there are a large number of immunomodulatory drugs that are prescribed to strengthen the immune system. In general, treatment with immunomodulators can last several weeks, and only a doctor prescribes such treatment. It should be noted that such treatment is possible if the cytomegalovirus is latent, so these drugs are used for prevention, but not for treatment.

Prevention

It is worth noting that cytomegalovirus is the most dangerous during the initial infection, so it is necessary to take all precautions when contacting already infected people and about preventing this infection. And especially such caution is very important for pregnant women who are not carriers of cytomegalovirus. Therefore, pregnant women, in order to protect their health and the health of the baby, need to give up casual sex.

Prevention of cytomegalovirus for everyone else comes down to observing the basic rules of personal and sexual hygiene.

1. You should not enter into new intimate contacts without a condom: this advice from doctors is repeated more and more often and is more relevant than ever.
2. When communicating with casual acquaintances, one should not use the same washing utensils and utensils, it is necessary to keep oneself and one's home clean, wash one's hands thoroughly after contact with money and other objects held in the hands of other people.

In addition, it is very important to work on strengthening the immune system, since a healthy immune system, even if cytomegalovirus accidentally enters the body, will not allow the development of an acute cytomegalovirus infection.

Chemotherapy for malignant neoplasms, immunosuppressive therapy for internal organ transplants) CMV causes severe disease (damage to the eyes, lungs, digestive system and brain) that can lead to death.

Prevalence and ways of infection with cytomegalovirus

• in everyday life: by airborne droplets and by contact - with saliva when kissing
• sexually: contact - with sperm, mucus of the cervical canal
• in blood transfusion and organ transplantation
• transplacental route - intrauterine infection of the fetus
• child infection during childbirth
• infection of the child in the postpartum period through breast milk from a sick mother.

Clinical manifestations of cytomegalovirus

The duration of the incubation period of cytomegalovirus is from 20 to 60 days. The acute phase of the disease lasts from 2 to 6 weeks: fever and signs of general intoxication, chills, weakness, headache, muscle pain, bronchitis. In response to the primary introduction, an immune restructuring of the body develops. After the acute phase, asthenia persists for many weeks, sometimes vegetative-vascular disorders. Multiple lesions of internal organs.

The most common CMV infection manifests itself as:

• SARS (acute respiratory viral infection). In this case, patients complain of weakness, general malaise, fatigue, headaches, runny nose, inflammation and enlargement of the salivary glands, with profuse saliva and whitish deposits on the gums and tongue.
• Generalized form of CMV infection with damage to internal (parenchymal) organs. There is inflammation of the liver tissue, adrenal glands, spleen, pancreas, kidneys. This is accompanied by frequent "causeless" pneumonia, bronchitis, poorly amenable to antibiotic therapy; there is a decrease in the immune status, the number of platelets in the peripheral blood decreases. Damage to the vessels of the eye, intestinal walls, brain and peripheral nerves is not uncommon. Enlargement of the parotid and submandibular salivary glands, inflammation of the joints, skin rash.
• Damage to the organs of the genitourinary system in men and women is manifested by symptoms of chronic nonspecific inflammation. If the viral nature of the existing pathology is not established, the diseases do not respond well to antibiotic therapy.

Pathology of pregnancy, fetus and newborn are the most serious complications of CMV infection. The maximum risk of developing this pathology occurs when the fetus is infected during pregnancy. However, it must be remembered that problems often arise in pregnant women with the activation of a latent infection with the development of viremia (the release of the virus into the blood) with subsequent infection of the fetus. Cytomegalovirus is one of the most common causes of miscarriage.

Intrauterine CMV infection of the fetus leads to the development of severe diseases and lesions of the central nervous system (mental retardation, hearing loss). In 20-30% of cases, the child dies.

Diagnosis of CMV infection

Diagnosis of herpesvirus (HSV and CMV) infections:

1. Diagnosis of HSV and CMV - infections can be diagnosed (especially with asymptomatic, atypical and latent forms of herpes) only on the basis of the detection of the virus in the biological fluids of the body (blood, urine, saliva, genital tract secretions) by PCR or by special cell culture. PCR answers the question: the virus is detected or not, but does not give an answer about the activity of the virus.
2. Seeding on cell culture not only detects the virus, but also provides information about its activity (aggressiveness). Analysis of the results of sowing against the background of treatment allows us to make a conclusion about the effectiveness of the therapy.
3. IgM antibodies may indicate either a primary infection or an exacerbation of a chronic infection.
4. IgG antibodies- they only say that the person met the virus, the infection occurred. IgG in herpesvirus infections persist for life (unlike, for example, from chlamydia). There are situations in which IgGs are of diagnostic value.

MAKE AN APPOINTMENT

Treatment should be comprehensive, including immune and antiviral therapy. Cytomegalovirus quite quickly leaves the periphery and ceases to be excreted from biological fluids (blood, saliva, breast milk) - a latent phase of infection sets in, - well-conducted immunotherapy activates the body's defense mechanisms that control the activation of latent CMV infection in the future.

Cytomegalovirus - CMV treatment is a rather difficult task. As, in fact, all viral diseases caused by pathogens adapted to modern drugs.

Poses a potential threat to human health. The virus is one of the most common opportunistic pathogens. When exposed to certain factors, it is activated and causes a vivid clinical picture of cytomegaly. In some people, the virus is in an opportunistic state throughout life, not showing up at all, but causing impaired immune defenses.

Of particular danger is the disease for infants and young children, when the virus covers all organs or systems, leading to serious complications, up to the death of the patient. There are still no known effective drugs for the complete expulsion of the virus from the body. If you are infected with cytomegalovirus, drug treatment is carried out to achieve a long-term therapeutic remission in a chronic course and eliminate local manifestations of the infection.

What you need to know about the virus

Cytomegaly appears to be an infectious disease of viral etiology. In some sources, there is a different name - cytomegalovirus infection (in the abbreviation CMV).

Cytomegalovirus is a member of a large group of herpesviruses. The cells affected by the viral agent increase significantly in size, hence the name of the disease - cytomegaly (translated from Latin - "giant cell"). The disease is transmitted through sexual, domestic or blood transfusion routes. The most unfavorable is the transplacental route of transmission.

The symptom complex resembles the development of a persistent cold, which is accompanied by a runny nose, malaise and general weakness, pain in the articular structures, increased salivation due to inflammation of the salivary glands. Pathology rarely has vivid symptoms, mainly proceeding in the latent phase. With generalized forms of damage to the body by viral agents, drug treatment and antiviral drugs are prescribed. There is no alternative effective treatment.

Many people are carriers of cytomegalovirus infection without even knowing it. Only 30% of the viral disease has a chronic course, exacerbated by local symptoms in the form of a herpetic rash, as well as general malaise. Antibodies to cytomegalovirus exist in 13-15% of adolescents, 45-50% in adult patients. The viral agent is often activated after exposure to factors that reduce immunity.

Cytomegalovirus poses a great danger to persons who have undergone organ or bone marrow transplantation, who have congenital forms of the disease or HIV status. The condition is dangerous during pregnancy, leads to serious consequences for the fetus: anomalies in the development of internal organs or systems, deformities and physical disability, miscarriage. For this, a collegial decision of the attending pediatrician and other narrow specialists is necessary.

Cytomegalovirus - treatment

The feasibility of therapy is proportional to the severity of the course and the potential danger to the patient's body. After some diagnostic measures, the risks of a possible threat are determined, an assessment is made of the pathological process. With signs of generalization, drug correction is prescribed. With a short episode of virus activation and while maintaining the patient's normal state of health, no special treatment is carried out. With a burdened clinical history of the patient, the doctor monitors the general condition, controls the level of antigen in the blood as part of laboratory diagnostics.

Often a completely healthy person who has been ill with a virus without any consequences acquires strong immunity. The viral agent itself, at the same time, remains in the body forever, transforms into a conditionally pathogenic form. There is a chronization of the pathology with periods of short-term exacerbations, subject to a pronounced decrease in immune defense. The goals of drug correction of the disease are:

• reducing the negative impact of the virus;
• relief of existing symptoms;
• ensuring stable remission in chronic disease.

Important! In humans, against the background of absolute health, the virus is asymptomatic, and the disease stops on its own. Many patients do not notice when the virus is activated and when its pathogenic activity is reduced.

The main indications for starting treatment

Unfortunately, cytomegalovirus is not treated completely. Medications can only strengthen local immunity and prevent new episodes of exacerbation. Therapy is prescribed in the following cases:

• immunodeficiency diseases of any origin;
• generalized spread of the viral agent;
• preparation of organ transplantation, for chemotherapy in oncological diseases;
• complicated clinical history of the patient (pathology of internal organs or system);
• pregnancy of a woman (often the first trimester);
• preparation for the treatment of encephalitis, meningeal infections.

The main symptoms and modern treatment of cytomegalovirus in women

Before determining treatment tactics, a differential diagnosis of cytomegalovirus infection with influenza conditions, SARS and other infectious diseases is carried out. It is the similarity of the symptoms of cytomegaly with the classic manifestations of the common cold and untimely or inadequate treatment that provokes the development of severe complications.

What funds can be assigned

So, during the examination, cytomegaloverus was diagnosed - drug treatment will be prescribed in most cases. Conservative and drug therapy are the only ways to correct the condition of patients with CMVI. Pharmaceutical forms are numerous: ointments (liniments) for external use, tablets for oral use, injections for intravenous administration, drops, suppositories.

To eliminate exacerbations of a viral disease, the following groups of drugs are prescribed:

• symptomatic (pain relief, elimination of inflammatory foci, vasoconstriction in the nose, in the sclera);
• antiviral (the main task is to suppress the pathogenic activity of the virus: Panavir, Cidofovir, Ganciclovir, Foscarnet);
• drugs to eliminate complications (multiple groups and pharmacological forms);
• immunomodulators (strengthening and restoration of the immune system, stimulation of the body's natural defenses: Viferon, Leukinferon, Neovir);
• immunoglobulins (binding and removal of viral particles: Cytotect, Neocytotect).

Drugs for the treatment of cytomegalovirus are prescribed in a complex manner. Additionally, vitamin complexes with an enriched mineral composition are prescribed to restore the overall resistance to colds and other chronic pathologies that lead to a decrease in immunity. In systemic autoimmune diseases, as a rule, lifelong drug therapy is prescribed.

Important! With cytomegaly in men, a high therapeutic effect was proved by Ganciclovir, Foscarnet, Viferon, in women - Acyclovir, Cycloferon and Genferon.

Drug treatment has a number of disadvantages due to side effects. The toxicogenic effect is often expressed in dyspeptic disorders, decreased appetite, and the appearance of allergies. Iron deficiency anemia often develops.

Antivirals

To achieve the maximum therapeutic effect, guanosine analogues are prescribed:

• Virolex;
• Acyclovir;
• Zovirax.

The active substance quickly penetrates the cells of the virus, destroys their DNA. These drugs are characterized by high selectivity and low toxicogenic properties. The bioavailability of Acyclovir and its analogues varies from 15 to 30%, and with increasing doses it decreases by almost 2 times. Medicines based on guanosine penetrate into all cellular structures and tissues of the body, in rare cases causing nausea, local allergic manifestations, and headaches.

In addition to Acyclovir, its analogues are prescribed Ganciclovir and Foscarnet. All antiviral agents are often combined with immunomodulators.

Interferon inducers

Interferon inducers stimulate the secretion of interferons within the body. It is important to take them in the first days of an exacerbation of the infection, since on day 4-5 or later their use is practically useless. The disease is running, and the body is already producing its own interferon.

Inductors inhibit the development of CMV, are often well tolerated by the body, promote the synthesis of immunoglobulin G, natural interferons, interleukins. Known drugs containing interferon include Panavir. The drug has a pronounced anti-inflammatory effect, helps with severe pain, reduces the intensity of unpleasant symptoms.

Viferon also helps with viral activity, has a convenient form of suppositories for rectal administration, which is convenient in the treatment of children of any age. Of the interferon inducers, Cycloferon, Inosine-pranobex and its analogues Isoprinosine, Groprinosin are isolated. The latter drugs have a low degree of toxicity, suitable for the treatment of children and pregnant women.

Immunoglobulin preparations

Immunoglobulins are protein compounds in the human body and warm-blooded animals that transport antibodies to pathogenic agents during biochemical interaction. When exposed to CMV, a specific immunoglobulin Cytotect is prescribed, which contains antibodies to cytomegalovirus. Among other things, the composition of the drug includes antibodies to the herpes virus type 1.2, to the Epstein-Barr virus. Therapy with immunoglobulins is necessary to restore the general protective resources of the body to the penetration of viral agents.

Doctor Komarovsky's opinion on cytomegalovirus

Another effective remedy for cytomegalovirus is Intraglobin (III generation), Octagam or Alphaglobin (IV generation). The latter types of drugs meet the most stringent requirements, suitable for patients with severe renal dysfunction (including pre-dialysis and dialysis periods).

To achieve maximum therapeutic results, immunoglobulins are prescribed in the form of injections (Pentaglobin). Medicines in the form of injections directly affect the root of the problem, quickly eliminate the symptoms of a generalized manifestation of the disease. In addition, the chemical composition of new generation drugs is not disturbed before interacting with altered cells.

List of the most effective drugs

Despite the wide range of remedies for the relief of CMV symptoms, doctors always build individual therapeutic tactics. Before prescribing a specific medicine, it should be clarified which symptoms of the infection are present in a particular patient. This takes into account: the patient's clinical history, age, weight, general somatic status, complications and other factors that may interfere with proper treatment.

For therapy, the following popular means are used:

• Foscarnet. Refers to antiviral drugs for the treatment of severe forms of pathology complicated by cytomegaly. It is prescribed for reduced immunity. The active substance destroys the pathogenic cell, breaks the biological chain of the virus, stops the reproduction of viral agents.
• Ganciclovir. Antiviral agent for the treatment of cytomegalovirus with a complicated course (diseases of the kidneys, liver, respiratory organs, generalized inflammatory foci). It is widely used to prevent congenital infections, especially if the virus in the mother's body is in the phase of active reproduction. Release form tablets and crystalline powder.
• Cytotec. Being an immunoglobulin, the drug is prescribed for the complex elimination of the infection. The tool compares favorably with low toxicity, the absence of specific and absolute contraindications. The drug is used to prevent large-scale damage by cytomegalovirus in various social groups. Among the side effects are back pain, hypotension, stiffness in the movement of the joints, dyspeptic disorders. If negative conditions appear, the medication is stopped and the doctor is consulted for an alternative prescription.
• Neovir. Belongs to a large group of immunomodulators. Available in solution for injection. It is used for therapeutic correction and prevention of the disease in children or adults with autoimmune diseases, other pathologies, which during the period of exacerbation greatly reduce local immunity. The dosage is determined individually in each case.
• Viferon. Widely used in pediatric practice. Available in the form of suppositories for rectal administration. It is used in the complex therapy of infectious diseases of any origin, complicated or simple in course. Effective for pneumonia, bronchitis, colds as a prevention of possible CMV. Among the side effects are allergic manifestations (itching in the perianal region, urticaria).
  
• Bischofite. Anti-inflammatory agent for the prevention and treatment of cytomegaly, herpes infection. Available as a gel in a tube or a balm in a glass container. Can be used as a topical remedy for blisters, rashes and inflammation. When applied externally, it resembles the effect of using mineral water, healing mud.

Be sure to use vitamins and other tonics that stimulate the work of many internal structures of the body. The most necessary for viral infections include vitamins C and B9.

Vitamin C is a powerful antioxidant, has regenerative properties, restores cells that are involved in the inhibition of the activity of pathogenic agents. B vitamins are necessary for the normal functioning of the nervous system, support the normal function of the bone marrow, and are responsible for the resistance of the immune system to external or internal negative factors.

Timely diagnosis and detection of severe forms of infection will reduce the level of complications, prevent the generalization of the pathological process. When stopping an exacerbation with a medical method, it is important to take into account a number of important criteria, to conduct a differential diagnosis. Preventive measures during a woman's pregnancy, in young children, as well as the correct treatment tactics will save patients from unpleasant manifestations of cytomegalovirus for a long time.

Cytomegalovirus is herpes type 5. In medicine, it is referred to as CMV, CMV, cytomegalovirus.

Doctors diagnose the disease using polymerase chain reaction (PCR) and enzyme immunoassay (ELISA). The patient receives a referral if symptoms of CMV are present.

If the response of a blood test to cytomegalovirus IgG is positive - what does this mean, a person must know for sure, because. the virus constantly lives in the body and carries the risk of exacerbation in a generalized form.

CMV is transmitted by airborne, contact and household routes. Unprotected sex and kissing also lead to infection with cytomegalovirus, since the infection is concentrated in the semen of men, and in women it is contained in the discharge from the vagina and cervix. In addition, the virus is found in saliva and urine. Positive cytomegalovirus IgG occurs in almost all adults.

The essence of the IgG analysis for cytomegalovirus is to search for specific antibodies in various biomaterials of a person who is suspected of having an infection. IgG is an abbreviation for the Latin word "immunoglobulin". It is a protective protein that is produced by the immune system in order to destroy the virus. With the entry of each new virus into the body, the immune system produces specific immunoglobulins, or antibodies. As a person grows older, there are more of them.

The letter G defines the class of immunoglobulins. In addition to IgG, there are antibodies of other classes:

If the body has never met with a certain virus, there will be no antibodies to it at the moment. If immunoglobulins are present in the blood, and the analysis shows a positive result, then the virus has entered the body. It is impossible to completely get rid of CMV, however, it may not bother its owner for a long time, as long as his immunity remains strong. In a latent form, viral agents live in the cells of the salivary glands, blood and internal organs.

IgG can be described as follows. These are antibodies against a specific virus that are cloned by the body from the moment they first appear. The production of IgG antibodies occurs after infection is suppressed. It is also necessary to know about the existence of fast immunoglobulins - IgM. These are large cells that react with maximum speed to the penetration of the virus. But this group of antibodies does not form immunological memory. After 4 - 5 months, IgM become useless.

The detection of specific IgM in the blood indicates a recent infection with the virus. At the current time, most likely, the disease is acute. To fully understand the situation, the specialist should pay attention to other indicators of the blood test.

The relationship of cytomegalovirus with immunity with a positive test

If a patient with strong immunity learns from a doctor that his cytomegalovirus hominis IgG is elevated, there is no need to worry. An immune system that works flawlessly keeps the virus under control and the infection goes unnoticed. Occasionally, a person notices causeless malaise, sore throat and fever. This is how mononucleosis syndrome manifests itself.

But even without pronounced signs of illness, a person should be less in society and refuse close contact with relatives, children and pregnant women. The active phase of the infection, which is manifested by an increase in IgG levels, makes a person a distributor of the virus. It can infect weakened others, and for them CMV will be a dangerous pathogen.

People with various forms of immunodeficiency are susceptible to cytomegalovirus and any pathogenic flora. In them, positive cytomegalovirus hominis IgG is an early sign of such serious diseases as:

• Encephalitis is brain damage.
• Hepatitis is a pathology of the liver.
• Retinitis is an inflammation of the retina that leads to blindness.
• Gastrointestinal diseases - new or chronic recurrent.
• Cytomegalovirus pneumonia - a combination with AIDS is fraught with a fatal outcome. According to medical statistics, death occurs in 90% of cases.

In patients with severe immunodeficiency, positive IgG signals a chronic course of the disease. Aggravation happens at any time and gives unpredictable complications.

CMV Igg positive during pregnancy and neonates

In pregnant women, the purpose of the analysis for cytomegalovirus is to determine the degree of risk of viral damage to the fetus. The results of the test help the doctor develop an effective treatment regimen. A positive IgM test adversely affects pregnancy. It signals the primary lesion or recurrence of chronic CMV.

The virus carries an increased danger in the first trimester during the primary infection of the expectant mother. Untreated, type 5 herpes causes fetal malformations. With relapses of the disease, the likelihood of a teratogenic effect of the virus on the fetus is reduced, but the risk of mutations still exists.

Infection with cytomegalovirus in the second or third trimester of pregnancy is fraught with the development of a congenital form of the disease in a child. Also, infection can occur at the time of childbirth.

If a blood test showed a positive result of cytomegalovirus IgG during pregnancy, which means such a response, the doctor should explain to the expectant mother. The presence of specific antibodies indicates the presence of immunity to the virus. But the fact of exacerbation of the infection is associated with a temporary weakening of the immune system.

In the absence of IgG to cytomegalovirus, the analysis suggests that the female body first encountered the virus after conception. There is a high risk of damage to the fetus and maternal organism.

A positive IgG in a newborn baby confirms that the baby was infected either during fetal development, or when passing through the birth canal of an infected mother, or immediately after birth.

An increase in IgG titer by 4 times in a two-fold blood test with an interval of 1 month confirms the suspicion of a neonatal infection. If in the first 3 days after birth, specific IgG to cytomegalovirus are detected in the blood of a child, the analysis indicates a congenital disease.

In childhood, cytomegalovirus infection can occur both asymptomatically and with severe symptoms. The virus gives quite serious complications - blindness, strabismus, jaundice, chorioretinitis, pneumonia, etc.

What to do if cytomegalovirus hominis igg is elevated

In the absence of obvious health problems and strong immunity, you can do nothing. It is enough to consult a doctor and let the body fight the virus on its own. Medicines designed to suppress viral activity are prescribed by doctors in extreme cases and only to those patients who have been diagnosed with immunodeficiencies of varying complexity, or have a history of chemotherapy or organ transplantation.

Strictly under the supervision of a doctor, patients with cytomegalovirus undergo treatment using the following means:
