How the Epstein Barr virus manifests itself in children. Treatment of children infected with the Epstein-Barr virus. How the virus is transmitted.

Good afternoon, dear readers!

Viral diseases affect all of us, but children are especially sensitive to them. Every year science releases new viruses that constantly mutate and take on new forms.

One of the most common is the Epstein-Barr virus, the symptoms of which we will consider in children.

The word "herpes" is familiar to many today. It is often associated with lip rashes. However, there are a lot of herpes viruses.

The onset of a rash after using amoxicillin is not uncommon. Confidence diagnosis requires an examination that confirms the presence of the virus or indirectly detects its presence. In most cases, patients recover without complications, and transmission of the virus can last from several months to several years. In immunocompetent patients, it is rarely fatal, but episodes of relapse may occur. Valgacyclovir is an alternative.

The best online environment for teaching and learning medicine and health. Professional, financial and personal return of teachers. For students, the best medical classes on the Internet! Transmitted by toxoplasma gondia, it does not usually show symptoms in immunocompetent patients and can be acquired in three different ways.

Some readers will sincerely ask the question: What is the Epstein-Barr virus? After all, such a diagnosis from pediatricians and district police officers almost never heard. Indeed, the asymptomatic nature of the disease does not allow to establish it in time, and mainly complications have to be treated.

Epstein-Barr infection also belongs to herpes.

From soil, sand and debris contaminated with faeces from pets such as cats. Its clinical picture is mixed with the clinical picture of mononucleosis in healthy people, since it manifests itself mainly as a localized adenopathy, which can be generalized in up to 30% of cases. Along with this picture, there may be such general symptomslike a fever, malaise, headache and fatigue. A less common patient may present with myalgia, arthralgia, abdominal pain, and monophagia in addition to maculopapular rash.

This disease is also called latent infection, since its symptoms often do not appear at all. It is transmitted by airborne droplets, but it can also pass after a blood transfusion.

Against the background of a virus infection, a significant decrease in immunity occurs. In this regard, complications and secondary diseases develop:

Laboratory tests are completely nonspecific and may show slight elevations in liver markers. Atypical lymphocytes are also present here. The gold standard, which is rarely used in healthy patients, is due to the imaging of Toxoplasma in body fluids or tissues. Treatment of mild forms in normal people need not be performed if this condition in pregnant women early in pregnancy complicates organ damage such as the heart or retina, the use of pyrimethamine with sulfadizine for one month is the therapy of choice, binding of folic acid to therapy.

lymphoma;
nasopharyngeal cancer;
hepatitis;
angina;
sclerosis;
chronic fatigue syndrome;
damage to the skin and mucous membranes.

The Epstein-Barr virus today is associated with and often causes cancer.

The most common complication is infectious mononucleosis, which affects lymphoma and leads to cancer. The incubation period ranges from 2 to 15 days, on average a week.

This syndrome is nothing more than a syndrome of mononucleosis, mediated by symptomatic seroconversion of those who acquired the virus, and occurs with an outbreak of plasma viremia. The clinical picture is typical for an acute viral syndrome with fever, pharyngitis, lymphadenopathy, headache, malaise and may be accompanied by an erythematous maculopapular rash. During this period, opportunistic infections were observed. Most patients recover from illness with a latency period for the virus, but up to 10% progress to the potentially fatal fulminant form.

Symptoms

Is it possible to determine the disease at home, because its symptoms have been erased? It is worth taking a close look at the sick child. Some of the symptoms below may help you:

temperature rise to 38-40 degrees (passes in waves):
severe intoxication;
weakness;
headache;
muscle pain;
joint pain;
angina;
fast fatiguability;
poor sleep;
swollen lymph nodes;
nausea;
abdominal pain, diarrhea;
sometimes - herpes rash;
leukopenia, thrombocytopenia.

When diagnosing, an analysis is made for the virus, for this a blood test is taken. If antibodies are present in it, then the child has an infection in the body. Only carefully collected data allow us to conclude that a virus is present in the body and must be treated.

With antiretroviral therapy in this phase, some patients experience negative effects from seroconversion, but most of them return with the return of viremia to the seroconverter. Several other diseases can be the cause of mononucleosis syndrome and should be investigated according to clinical suspicion. Among the others infectious diseases we can mention secondary syphilis, leptospirosis, hepatitis virus infection, herpes virus infection and others. For non-infectious reasons, we must take into account lymphomas, allergic conditions and adverse reactions to medicines, of which they are most commonly associated with phenytoin and carbamazepine.

Types of manifestation

Unfortunately, the statistics are disappointing. Almost 90% of the world's population are infected with this infection and are its carriers.

The Epstein-Barr virus can manifest itself in different ways, so it can only be detected using special tests:

Infectious mononucleosis is sometimes called mono or kissing. It is most commonly caused by the Epstein-Barr virus, which is found in the herpesvirus family of organisms. In most cases, the virus is inactive, but sometimes the virus multiplies and is spilled in saliva and other body fluids.

primary infection - in most cases it is asymptomatic, immunity is acquired for a long time. But if the patient has weak immunity, there is a risk of developing mononucleosis;
chronic form - the symptoms are erased, so it is very difficult to diagnose the disease;
generalized chronic form - affects the kidneys, central nervous system, myocardium;
erased form of secondary immunodeficiency;
oncological manifestations;
autoimmune diseases.

Clinical manifestations are expressed in three forms:

Gaining facts about infectious diseases

The Epstein-Barr virus spreads from one person to another in saliva, blood and other body fluids. Close contact is usually required, such as kissing or sexual contact. Although infection can occur at any age, mononucleosis is most common in people between the ages of 15 and 30.

When there are signs and symptoms of mononucleosis, they usually include the following.

Sore throat, including white patches at the back of the throat.
Swollen lymph glands in the back of the neck, groin, and armpits.

In addition to these classic symptoms, some children may have one or more of the following signs and symptoms.

asymptomatic form;
respiratory syndrome;
mononucleosis.

Unfortunately, the disease can only be cured by early stageuntil it took on more severe forms. But since most of the planet is infected with the infection, it remains only to talk about the formation of persistent immunity to the virus.

How to treat?

Treatment includes a whole range of measures:

Decreased appetite Enlarged liver and spleen Increased sensitivity to light. This virus can cause several types of cancer. It is unclear why some people infected with the virus get cancer while the vast majority do not. This serious infection can lead to liver failure, a decrease in blood cells, or cancer, and is often fatal. The incubation period of infectious mononucleosis is 30 to 50 days.

When to call your pediatrician

See your pediatrician if your child has the underlying symptoms described here, especially fever, sore throat, fatigue, and enlarged glands. The diagnosis of infectious mononucleosis is usually made through medical history, physical examination, and blood tests. These tests may include a complete blood count to check for unusual-looking white blood cells.

antiherpetic drugs;
interferons;
etiotropic drugs (Acyclovir, Foscarnet, Valacyclovir), Groprinosin (the effectiveness of any antiviral drugs Until proven, studies have shown that after the use of these drugs the number of patients almost did not decrease);
immunoglobulins;
antibiotics (according to indications, if a secondary infection joins);
vitamin and mineral complexes;
hepatoprotectors (blood thinners);
antipyretic;
antihistamines (for allergies).

Inosine pranobex (Groprinosin) remains one of the leading drugs in treatment. It inhibits the synthesis of viral proteins. It slows down the synthesis of the RNA of the virus. As a result, the infection cannot multiply.

Most treatment for mononucleosis aims to make your baby more comfortable until the infection goes away on its own. Some pediatricians may recommend giving your boy acetaminophen to reduce fever and relieve pain.

A sore throat can be treated by gargling with hot water and salt.
Bed linen can be important for child fatigue.

Because the virus causes mononucleosis, infected children should not be treated with antibacterial agents.

Children with infectious mononucleosis should not participate in sports until the swelling of their spleen has disappeared. If the body enters an area with an enlarged spleen, the spleen can rupture or rupture, leading to internal bleeding that can lead to death. Keep in mind that this is unusual and that mononucleosis is rarely fatal.

The second most important drug in treatment is an analogue of human interferon. It further inhibits reproduction and destroys the RNA template.

The therapy also imposes some restrictions on the child's lifestyle. A sparing diet is prescribed, because of the possible enlargement of the spleen, such children should not go in for sports, heavy physical exertion is contraindicated, since the spleen can rupture. In the acute course of the disease, bed rest should be observed.

Most cases of infectious mononucleosis disappear after 1-3 weeks. Patients with an abnormal immune system can have a more severe infection that further weakens the immune system, leading to cancer or death caused by liver failure and bacterial infections.

It is difficult to prevent the spread of this virus because people who have been infected can spread the virus for the rest of their lives. Your boy should avoid contaminated saliva by not sharing drinking glasses, water bottles, or utensils.

Unfortunately, the effectiveness of the treatment has not been conclusively proven. Doctors are desperately arguing about the effect of interferon and its benefits for the body.

There is an opinion that the introduction of artificial interferon only prevents the body from fighting the infection on its own, because, receiving help from the outside, our body begins to be lazy and does not produce its own interferon. As a result, immunity falls, and treatment requires more and more doses of interferon from the outside.

There is no vaccine to protect against infectious mononucleosis. When to share and when not to share? Your child should not share drink glasses, water bottles, or utensils that can carry contaminated saliva. The information contained on this website should not be used as a substitute medical care and the advice of your pediatrician. There may be variations in treatment that your pediatrician may recommend based on individual facts and circumstances.

Children and adolescents with mononucleosis can have flu symptoms that go away on their own after a few weeks of rest and plenty of fluids. Mono is usually caused by the Epstein-Barr virus, a very common virus that most children are exposed to at some point during their growing up. But adolescents and young adults who become infected often develop mono.

On the other hand, if a child has an acute course of the disease, neither the parents nor the doctor are able to sit and wait "until it passes by itself." Despite side effects drugs, they are prescribed, and some positive results are recorded.

Unfortunately, parents are not able to completely protect their child from infection. It remains to strengthen the immune system so that the baby suffers the disease asymptomatically and develops antibodies to it.
Mono is spread by kissing, coughing, sneezing, or any contact with the saliva of a person infected with the virus. It can also be spread by sharing straw or tableware. Researchers believe that mono can be spread sexually as well.

It is likely that those who have had monosymptoms do not get sick or do not show symptoms again. Symptoms usually appear about 4-7 weeks after exposure to the virus and may include. Very tired fever sore throat with swollen tonsils, which may have white patches; loss of appetite; swollen lymph nodes; headaches; muscle pain; weakness; pain in the abdomen or spleen; rash; abdominal pain. Mono symptoms usually go away within 2-4 weeks. However, in some teens, tiredness and weakness can last for months.

Until next time, friends!

It was discovered in the sixties of the last century by the scientist M.E. Epstein and his assistant I. Barr during microscopic studies of cells of a malignant tumor, which later came to be called Burkitt's lymphoma.

transmission path

To make a diagnosis, a doctor may do a blood test and physical exam to check things like swollen tonsils and an enlarged liver or spleen, which are often signs of infection. Doctors recommend that children who receive mono avoid sports for at least a month after symptoms have disappeared, because the spleen usually enlarges temporarily from the disease. An enlarged spleen can easily rupture - causing internal bleeding and abdominal pain - and requires emergency surgery.

Most children who receive mono recover completely without problems. These can include liver or spleen problems, anemia, meningitis, difficulty breathing, or heart inflammation. There is no vaccine to protect the Epstein-Barr virus. But you can protect your kids from mono by making sure they avoid close contact with anyone who has it.

They become infected in childhood and adolescence. Although the features and its distribution have been studied for 40 years, they remain not fully understood. Infected by aerosol, transmissible, and it can also be transmitted through contact with an infected person, through mother's milk and sexually (through oral sex).

Infection in childhood occurs through toys on which the wearer's saliva remains hidden form... Among adults, it is common to spread dangerous virus when kissing with saliva. This method is considered very common and familiar.

Many people who have mono do not have symptoms, but they can still pass them on to others. Therefore, children should wash their hands well and often and not share drinks or eat utensils with other people, even people who seem healthy. The best treatment for mono is plenty of rest, especially at the onset of the illness when the symptoms are most severe. Acetaminophen or ibuprofen can help relieve fever and muscle pain. Never give aspirin to a child who has a viral illness because its use is associated with Reye's syndrome, which can lead to liver failure and can even be fatal.

Entering the salivary glands, thymus, cells of the mouth and nasopharynx, the Epstein-Barr virus begins to infect the human body. With a decrease in immunity, the latent one can turn into an open form, causing a number of dangerous diseases.

Pathogenesis

There are 4 stages in the pathogenesis:

At the first stage it is introduced into the oral cavity and nasopharynx, it enters the salivary ducts, into the nasopharynx, where it multiplies, infecting healthy cells.

In the second stage enters the lymph nodes through the lymphatic tracts, damage to B-lymphocytes and dendritic cells occurs, causing their avalanche-like reproduction, this leads to swelling and enlargement of the lymph nodes.

Stage three - the central nervous system and lymphoid tissues are affected, along with other important organs: heart, lungs, etc.

Stage four characterized by the development of specific immunity against the virus, in which the following result is obtained:

complete recovery;
or the infection becomes chronic.

Two forms are known - typical and atypical. A typical one has all the symptoms, characteristic diseases, in an atypical one - only 2-3 symptoms (maybe even one). Atypical ones are detected on the basis of laboratory test data.

In terms of severity, it can be in mild, medium-severe and severe forms. In severe cases, the body temperature reaches its maximum, a feverish state lasts for a long time, the lymph nodes, as well as the spleen, and sometimes the liver, become greatly enlarged.

Adenoiditis persists for a long time, the tonsils are strongly hyperemic, the tongue is coated, the leukocyte count in the general blood test is higher than normal.

Diagnostics

Diagnosis is carried out on the basis of patient complaints, according to the manifestations of primary symptoms and data from laboratory blood tests.

Important for the diagnosis are:

1. Indicators general analysis blood. After the introduction of the B virus, the lymphocytes become infected, and their active reproduction begins. The process leads to an increase in their concentration in the blood. Such cells have received the scientific name "atypical mononuclear cells".

In infected individuals, ESR, the number of leukocytes and lymphocytes are above normal. Platelets also increase or, on the contrary, may be reduced, the same with hemoglobin indicators (hemolytic or autoimmune anemia is observed). When viewed under a microscope, doctors identify them.

2. To accurately determine the infection with the virus, take blood for tests to identify antibodies against antigens... When antigens enter the bloodstream, they are recognized by the cells of the immune system.

3. A biochemical analysis of blood taken from a vein on an empty stomach reveals a protein in the acute phase, elevated bilirubin levels indicate liver disease.

ALT, AST, LDH are special proteins found in the cells of the body. When an organ is damaged, they enter the bloodstream, and their increase indicates a disease of the liver, pancreas or heart.

4. A consultation of narrow specialists is held with the involvement of an immunologist and an ENT doctor, oncologist and hematologist. The final conclusions are made on the basis of clinical studies with a blood clotting test, x-rays of the nasopharynx and chest, Ultrasound of the abdominal organs.

Initial symptoms of the virus Epstein Barr, indicative of patient infection

Incubation period acute form lasts about a week after implementation. The patient begins to develop a picture similar to an acute respiratory illness.

These are the initial symptoms:

the temperature rises to critical indicators, the patient shivers;
sore throat, plaque can be seen on swollen tonsils;
on palpation, an increase in lymph nodes is felt under the jaw, on the neck, in the groin and armpits.

In the analysis of blood, the appearance of atypical mononuclear cells is observed - young cells that are similar to lymphocytes and monocytes.

A person gets tired quickly, appetite and performance decrease. A papular rash can be seen on the body and hands. The activity of the gastrointestinal tract is disrupted. Sore muscles and joints can often be found in patients. They often suffer from insomnia and chronic fatigue syndrome.

Associated diseases

The most dangerous disease, which can cause, is considered Filatov's disease, or it is also called infectious mononucleosis. The incubation period of this disease is usually about a week, but can last up to 2 months.

At the beginning, the patient begins to feel chills and malaise, joint and muscle pains, the throat swells, the patient gets tired quickly, and does not sleep well.

The body temperature gradually rises and reaches critical - up to 40 degrees, the patient has a fever. The main defining symptom viral infection polyadenopathy is considered, which appears 5-6 days after manifestation and is characterized by an increase in all lymph nodes. They become slightly painful during palpation.

Nausea and pain in the abdomen leads to vomiting. The skin remains unchanged, but herpetic eruptions are sometimes observed. The palatine tonsils become inflamed, with back wall pus is discharged from the pharynx. Nasal breathing becomes difficult, accompanied by a nasal voice.

Later, the spleen enlarges (the phenomenon of splenomegaly), which returns to normal in 2-3 weeks. It is accompanied by the appearance of a rash on the body, papules and spots, roseola points, as well as hemorrhages.

Sometimes there is mild jaundice with dark urine.

A person who has had infectious mononucleosis will no longer get sick, but will remain a carrier for life. The Epstein Barr virus is dangerous for its complications: meningoencephalitis, serous meningitis, and there may also be a threat of encephomyelitis.

Those infected with the Epstein-Barr virus can develop other diseases:

lymphogranulomatosis;
systemic hepatitis;
lymphoma, including Burkitt's lymphoma;
malignant tumors of the nasopharynx;
neoplasms in the salivary glands, gastrointestinal system;
herpetic lesions of the genitals and skin;
hairy leukopenia; chronic fatigue syndrome;
multiple sclerosis;
proliferative syndrome, which develops in those who have acquired immunodeficiency or from birth.

With the development of infection, B - lymphocytes increase so much that the functioning of important internal organs is impaired. Many children with congenital immunodeficiency die from this disease. Those who survive suffer from lymphoma, anemia, agranulocytosis, or hypergammaglobulinemia.

Treatment

Boy Epstein Barr

The infection should be treated by a doctor who specializes in infectious diseases, and if a tumor is detected in the form of neoplasms, an oncologist. Patients with severe infectious mononucleosis are subject to immediate hospitalization with the appointment of an appropriate diet and bed rest.

Active treatment begins with the use of drugs to stimulate phagocytes and natural killer cells, creating an antiviral state of healthy cells.

The effectiveness of such appointments has been proven:

interferon preparations - alpha: acyclovir and arbidol, viverone, valtrex and isoprinosine;
intramuscular injection of roferon and reaferon-EC;
intravenous administration of immunoglobulins such as pentaglobin and intraglobin, which also give good results;
immunomodulatory drugs: derinat, lycopid and leukinferon;
biological stimulants (solcoseryl and actovegin).

An auxiliary role in the treatment is played by the complex intake of vitamins and antiallergic drugs, such as tavegil and suprastin.

If purulent sore throat is detected, a course of antibiotics is prescribed for a week or for 10 days (cefazolin or tetracycline).

With an increase in body temperature, antipyretic paracetamol tablets are prescribed, and when coughing, mucaltin or libexin tablets are prescribed. With difficulty breathing through the nose, naphthyzine drops help.

Patients can be treated on an outpatient basis by prescribing interferon-alpha under systematic laboratory control. After three to four months, blood must be donated for biochemical analysis for immunological examination and PCR diagnostics.

The treatment may take two to three weeks or several months, depending on the severity and complications, as well as its types (acute or chronic).

If a disease is detected, the saliva of the rest of the family should be examined in order to avoid re-infection.

Why Epstein Barr is dangerous

On the face

It is a serious danger for its complications. At the very beginning of the disease, in the very first weeks, it can lead to damage to the central nervous system. Often there are meningitis, psychosis and hemiplegia.

Sometimes the Epstein Barr virus provokes autoimmune hemolytic anemia. The emerging pain in the abdomen, radiating to the left shoulder, may indicate a ruptured spleen. With strong swelling of the tonsils, obstruction of the upper respiratory tract is sometimes observed.

During pregnancy, the Epstein Barr virus can cause intrauterine infection of the fetus and lead to pathology of its important organs and lymph nodes.

Preventive measures against Epstein Barr virus

You should not be afraid of the virus, since it is impossible to avoid infection. Adults already have immunity, as they have antibodies to the Epstein-Barr virus developed after an illness in childhood.

If a child has a good immune system, it shouldn't be overly protected from infection. It has been noticed: the earlier children get sick with the Epstein Barr virus, the weaker the course of the disease will be. Maybe they won't even feel it. And immunity will be developed for life in children who have been ill.

For those with weak immunity, a special vaccine is currently being developed to protect the body from infection with this virus.

The most effective prevention is considered to increase the resistance caused by the Epstein Barr virus, strengthening the immune system.

Here are the mandatory prevention measures:

Hardening from birth is recommended. Kids should be gradually taught to swim in warm water with body temperature and walk in the fresh air, and will also help in hardening the application cold water for douches throughout life.
Leading a healthy lifestyle, competently, scientifically it is necessary to properly formulate a balanced diet with the introduction of fresh vegetables and fruits. Vitamins and trace elements contained in them, special multivitamins should support the body at a high level.
Avoid any somatic diseases that weaken the immune system.
Psychological and physical stress also negatively affects the state of the body and reduces immunity.
We have to live with the motto “movement is life”, spend a lot of time outdoors in any weather, do feasible sports: skiing in winter and swimming in summer.
