Herpes virus types (1,2,3,4,5,6,7,8): symptoms and treatment Skip to content. Treatment and symptoms of the herpes virus type six in children and adults - a list of drugs and prevention How type 6 herpes is infected

Speaking of herpes, many parents imagine a classic picture - an unpleasant blistering rash crawls out on the lip or nose, it itches and itches. Many are sure that it appeared due to hypothermia, a cold. In fact, everything is much more complicated. Herpes is a virus. There are 8 herpetic viruses in total. The most “childish” of them is the herpes virus type 6 in children.

What it is?

Medical science has studied the five herpetic viruses well and in detail, with respect to the rest there are still more questions than answers.

The first is the herpes simplex virus., which appears in the form of blistering plaques on the lips, mucous membranes of the nose, less often in the mouth and throat. It has nothing to do with colds. Although the truth is that it is hypothermia that can become a trigger for the activation of the virus, which had previously quietly existed in the body and did not manifest itself.

The second type of herpes virus- this is a very unpleasant member of the family, which causes a genital infection. It manifests itself as a small watery rash in the genital area and is quite dangerous for pregnant women.

herpetic virus type 3 well known to all adults, it calls childhood disease- chickenpox, which is also popularly called "chickenpox".
Fourth herpetic representative- Epstein-Barr virus, which, if all favorable circumstances coincide, can cause meningitis, toxic hepatitis, and even oncological tumors.

Fifth type of viruses has a well-defined name - cytomegalovirus. It causes a very specific disease - cytomegaly.
Herpetic viruses of the sixth, seventh and eighth types have not yet been sufficiently explored. They do not yet have names, they are designated by the letter abbreviation VG-6,7,8. Of this mysterious trinity, the sixth virus is the most studied. As for the seventh and eighth, scientists managed to formulate and describe only the symptoms, and quite approximately.

The seventh type of herpes virus causes chronic fatigue, frequent depression, swollen lymph nodes and a temperature that can stay without dropping and visible reasons several months.

Eighth herpes infects cells immune system, causing the occurrence of lymphomas, including oncological lesions of the lymphoid tissue.

How does it work?

To understand how VG-6 “works”, you need to understand the principle of the impact of all herpetic viruses, it is approximately the same for each type. Once in the human body, such a virus never leaves it. After the acute stage (and most of the diseases caused by these viruses are of an acute and violent nature), a period of calm begins - the virus exists quietly. A relapse is the result of exposure to certain factors - stress, hypothermia, weakened immunity due to another disease.

Herpes viruses have their own DNA, they can contact the immune system of their carrier, and therefore remain with a person for life. These agents affect not only people, but also animals, as well as birds.

Once in the body, the herpetic aggressors insert their own DNA into the affected target cells, forcing them to refuse to perform their duties and begin to ensure the vital activity of the virus itself.

According to the degree of prevalence, aggressiveness, structure of their genome, all herpesviruses are divided into alphaherpes, betaherpes and gammaherpes.

The sixth type of herpes also has conditional classification. It is divided into two types - 6A and 6B. Both are distributed in such a way that they are found in the blood of 95% of the world's population. 6A is considered a neurovirulent virus that can infect nerve cells, spreading most often through the bloodstream. As an assumption, scientists put forward the version that 6A is the root cause of the development of multiple sclerosis, but there is not enough evidence yet.

6B causes such a mysterious disease in children as sudden exanthema, which is also called infantile roseola (and which received another name for the type of pathogen - "sixth disease"). Children are at risk, and the youngest representatives of humanity are babies under 2 years old. Many affected children are between the ages of 9 months and a year.

Danger

In fairness, it should be noted that the herpes virus 6A is dangerous only for those who have pathologically reduced immunity. This condition should be understood not as a runny nose and frequent acute respiratory viral infections, but serious illness immune system (this is, for example, HIV infection). When parents say that a child has weak immunity, these statements in most cases have nothing to do with real immune weakness.

The most common is the 6B virus. Many carriers are not even aware that a foreign agent with its own DNA lives in their body.

Even if pink roseola one day manifests itself, after that the human immunity will suppress the activity of the virus all his life, due to which it is possible not to get sick with an acute infection anymore.

Considering that most of the adult population has such a virus in their body, the child usually becomes infected in the very first months of his independent life in this world. Most often, it is infected from the mother. Herpesvirus is usually spread through saliva.

Many pediatricians believe that the sixth herpes type B is not very dangerous. Possible negative consequences can only be associated with those symptoms that, in the acute stage of the disease, are themselves dangerous for babies under 2 years old. This is a high fever that can cause convulsions, loss of consciousness, dehydration, disturbances in the activity of the central nervous system.

Quite rarely, herpesvirus type six causes complications such as meningitis, pneumonia, and inflammation of the heart muscle. In most children, the disease remains unidentified - the pediatrician determines acute respiratory infections or acute respiratory viral infections, the mother feeds the crumbs compote for 3-5 days, and this is where it all ends. And only then, when there is a need to do a blood test for antibodies, the laboratory assistant will identify specific antibodies to the sixth type of herpes virus.

Symptoms

Usually incubation period lasts up to half a month. The active phase of the disease (roseola) begins with a sharp increase in temperature. The thermometer can rise to 39.0-40.0 degrees. There are usually no other symptoms - no runny nose, no cough, no intestinal manifestations are observed. True, they may slightly increase The lymph nodes- submandibular, cervical and occipital.

It is possible to suspect a herpetic viral infection only after 3-4 days, when the temperature drops. The fact is that after a fever and fever during the day, the baby is covered with a pink blistering rash. He still has no complaints, the rash does not cause inconvenience and discomfort. It can last for about a week or a little more, then it passes without leaving scars, scars, marks, without changing skin pigmentation.

The rash is 3-5 mm in size (each fragment), often a white border can be seen around the pimple. The greatest number of rashes in a child is observed on the face, back and abdomen.

Diagnostics

The manifestations of the sixth herpes are quite difficult to recognize even for a very good doctor. Mom usually calls the doctor for initial stage diseases when the baby has a high temperature. There is no rash or other characteristic signs of a herpetic lesion at this moment, so the doctor most often diagnoses SARS.

If the doctor was invited at the stage of rash formation, then the first thing he would think is rubella. The rash is very much like rubella. Diagnosis at this stage will be to exclude rubella, for this the baby will take blood for analysis.

Roseola is often mistaken for an allergy. Having established the first diagnosis (“SARS”), the doctor will definitely prescribe several syrups, rectal suppositories, and tablets. The definition of a rash as a manifestation of a drug allergy would be quite justified, but it cannot be called correct.

Due to the combination of the above reasons, the diagnosis of "roseola" is quite rare in Russian pediatrics, and the fact that the child has been ill with it, parents begin to guess much later, after reading articles about the sixth herpes (or when the presence of antibodies to VH- 6).

Treatment

The infection caused by the herpes virus of the sixth type does not need special treatment. Many pediatricians are inclined to this point of view, although there are also such representatives of the profession who (even realizing that the baby almost certainly has roseola) prescribe an impressive list of antiviral drugs.

Usually, the child's immunity copes with a foreign agent on its own, in 3-5 days. The drug manufacturers set the same terms as the duration of the course of treatment.

It is up to parents to decide whether or not to pay for drugs that do not affect the recovery process. However, it is still worth asking the doctor who prescribed antiviral therapy how these drugs will help and whether they will help at all.

Since the herpes virus is considered lifelong, it cannot be cured. However, it is possible to alleviate the child's condition with severe course and severe symptoms. For this, there are drugs designed specifically for the treatment of herpetic diseases. This, for example, "Acyclovir".

Ointment "Acyclovir" can be used to treat rashes if they cause discomfort to the baby. Parents may be confused age limit in the instructions for use of the drug - for children from 3 years. But such a restriction by the manufacturer is not established because the ointment harms children under three. The effect on the body of an infant is poorly understood; experiments on children were not performed for ethical reasons.

The ointment can be used for roseola caused by the sixth herpes, in dosages that will be half as low as stated by the manufacturer. If the child is already a year old, you can give "Acyclovir" in tablets, strictly observing the dosage and remembering the duration of the course of treatment.

In a very severe form of the disease (which is extremely rare), the child is hospitalized and intravenous infusions of Acyclovir are given to him in a hospital of an infectious diseases hospital.

Considering all of the above, it can be noted that the treatment of manifestations of herpes of the sixth type with symptoms that are mild, expressed in moderate and moderate degrees should be carried out according to a reasonable scheme:

Antipyretic drugs in the first stage of the disease. High temperature (from 38.5) can be reduced with the help of "Paracetamol", "Ibuprofen" - in the dosage allowed by age. Rubbing with alcohol and cold water are not recommended, because they disrupt heat transfer, can cause vasospasm.

Antiherpetic drugs in the second stage of the disease. Cream and ointment "Acyclovir" ("Zovirax"), tablets "Acyclovir" for children from one year old. The use of the drug "Isoprinosine" is not entirely justified, since it shows some activity only against herpesvirus types 1-5 (inclusive). It has no effect on herpes of the sixth type, it does not weaken the symptoms.

There are no preventive measures against the sixth herpes virus, there are no vaccinations against it. You should be aware of this, but you should not get depressed.

In stage acute illness For parents, some useful tips to help alleviate the condition of the child are useful:

At the initial stage of the disease, which occurs against the background of a fever, you should provide the baby with a plentiful drinking regimen in order to prevent dehydration. You should drink often, little by little, the drink should be warm. It is very good if the temperature of the liquid is equal to the temperature of the body - so the drink will be more quickly absorbed by the body.

The minimum amount of liquid can be calculated simply: the baby's weight must be multiplied by 30. The resulting number in grams will indicate the physiological need for liquid.

From the first hours after the temperature rises, the child is contagious to others., it should be isolated from communication with other children. It will be contagious throughout the acute period, and with the appearance of a rash, it will cease to be a source of infection. He will be able to walk, communicate.
The baby in the first few days should be provided with a calm regimen. It is best to put him to bed, ventilate the room more often, make sure that it is not very hot in it (no more than 20 degrees Celsius).

It is not always necessary to use antiherpetic agents, but only when the rash in the second stage of the disease causes inconvenience. The kid combs her, she interferes with his sleep (this happens if the room is hot enough, the baby sweats in his sleep). It makes no sense to cauterize the rashes with alcohol, antiseptics.
For severe infection(if a child has vomiting added to the fever), be sure to use oral rehydration agents - these are Regidron, Humana Electrolyte, Smecta and other drugs.
Folk remedies to treat herpes is not worth it, because even pharmaceutical preparations by and large, they are powerless against him, to say nothing of garlic, aloe juice and earwax, which they love to smear any herpetic rashes of their grandmother.
After an illness, special attention should be paid to strengthening the immunity of the child., because a strong immune system will not allow a relapse. To do this, you need to ensure that the child's diet is rich in vitamins, trace elements, minerals, so that the baby spends enough time in the fresh air. If you have not done hardening before, it's time to try and make these procedures systematic.

The child should actively move, attend the sports section (as far as possible), spend less time at the computer or in front of the TV. Be sure to do all the age-appropriate preventive vaccinations. They do not protect against herpes infections, but significantly reduce the risk of contracting other viral diseases that greatly undermine the state of the child's immune defenses.

All these measures will balance the "opportunities" of herpes and immunity, and the virus will remain in a "sleeping" state, without interfering with the full and rich life of the child in the future.

Dr. Komarovsky talks about the herpes virus and its varieties in the next video. You can also read more about Dr. Komarovsky's opinion on type 6 herpes in children in another article.

To date, the human herpes virus type 6 (HHV-6) has been the least studied. It was found relatively recently, in 1985-1986, but, nevertheless, the scale of distribution does not allow us to consider it insignificant and harmless.

The disease that causes this type of herpesvirus is divided into 2 types:

Herpes virus 6 A (or HHV-6 infection);
Virus 6 B (or HHV-6-B infection).

Like other herpes viruses, HHV is completely incurable. Currently, no such medicines have yet been created that could remove the virus from the body without a trace and prevent its return.

Most often, a patient who has been ill once develops immunity, as a result of which the external manifestations of the disease become invisible or become mild. However, the absence of external signs of the presence of strains in the body does not mean that they complete absence. They continue to be in it, waiting for the right opportunity to show up again (usually even a slight weakening of the immune system, SARS, colds, and the like is enough for the successful development of the virus).

As a rule, everyone is born with immunity to this disease, since it is transmitted from the mother. But, in the absence of these antibodies in the mother (this happens if she did not suffer from pathologies that are caused by the presented microorganisms), the child, usually during the first year of life, becomes infected and a protective mechanism forms independently.

Often herpes type 6 is confused with the similar HHV-7. Therefore, it is almost impossible to accurately determine the type of strain in a particular person.

Virus subtypes

There are several varieties of herpesviruses of the 6th group, characterized by their defining features:

Subspecies A. Herpes type 6 in adults has subspecies A. It is also known as a neurotropic infection. Herpes simplex virus type 6 (HSV-6) group A in adults usually gives complications to the activity of the central nervous system, which can later cause the development of sclerosis. Especially often the disease is observed in patients with poor health, for example, in patients with HIV.
Subspecies B. Herpes virus type 6 in children is more common of this particular subspecies.

On the this moment the herpes virus type 6 has not yet been attributed to its individual signs. It is only known that if a person falls ill with it for the first time, then, as a rule, the signs of the manifestation of the disease are fixed in the form of roseola, and there are also a number of diseases whose connection with herpes has not yet been definitely proven, however, the frequency of occurrence of such in infected people is much higher .

These diseases include:

chronic fatigue;
diseases of the central nervous system;
lymphadenitis;
febrile convulsions;
mononucleosis and some others.

V rare cases aggravation of the course of the disease and the development of such diseases as:

malignant limf;
lymphoproliferative pathologies.

It should also be noted that the sixth herpes virus can have a detrimental effect on the development of a child while still in the womb. With a strong infection, even the death of the baby is possible.

Also, HHV-6 can initiate the development of the following pathologies:

HIV infection;
diseases of the ENT organs.

Symptoms

Often this virus affects children due to weak immunity. The onset of infection with a type 6 virus in a child is indicated by a slight subfebrile temperature, which lasts for 2-3 days and is accompanied by a slight fever. The disease can then follow several paths.

Light form

Herpes type 6 in children can go away in a fairly mild form, and therefore it can be confused with diseases similar in symptoms (rubella, chicken pox, etc.). However, a detailed analysis will help to accurately establish the nature of the unhealthy condition. It is also possible for the parents themselves to determine the disease - in case of pressing on skin rashes, they will change color to white, which cannot be observed with rubella.

In general, this path of development and manifestation of the disease is characterized by itchy skin rashes on such parts of the body as:

back;
limbs;
stomach;
there are single rashes in the throat and on other mucous membranes of the body.

Signs of the 6th type of herpes in a child

complex shape

If the infection has gone along the second path of development, then in addition to skin rashes, the child has:

a sharp increase in temperature;
fever;
convulsions are possible.

This form of manifestation may be accompanied by purulent discharge from the nose, coughing, vomiting and other unpleasant conditions. After the manifestation of these symptoms, you should immediately consult a specialist.

Testing for the presence of infection should be done at the first symptoms, because this disease can be complicated, causing such consequences:

pneumonia;
hepatitis;
myocarditis;
meningoencephalitis.

Features in adults

Herpes type 6 in adults is not excluded, the symptoms of which will manifest themselves when conditions favorable for the development of pathology are formed. As a rule, any adult, having been ill in childhood, received lifelong immunity to this infection.

The strain of the virus is dormant in the body, waiting for a convenient opportunity to reappear. The development of the disease is favorably affected by the weakening of the immune system, fatigue, various diseases. If the disease was not previously tolerated, then in adults the symptoms appear similar to children.

Currently, overwork is a particularly common cause of the development of the herpes virus type 6 in adults. This is due, first of all, to the ever-increasing role of intellectual and mental stress in life.

The following symptoms may signal the presence of HHV-6:

aggressiveness, intolerance;
chronic fatigue;
general depressed state;
apathy;
constant stress.

How HHV-6 is transmitted

There are several ways to transmit the virus to the human body:

Through blood - transfusion. It is worth being extremely careful with this manipulation, because many serious diseases are transmitted along with blood, which do not have the possibilities and methods of treatment, including AIDS.
From mother to child - a mother's blood and vaginal secretions may be positive for the strain. In this case, the virus is transmitted to the baby during childbirth. It is important that the virus cannot be transmitted from mother to baby during breastfeeding. However, contact of an infected person with a newborn, especially kissing, should be avoided, as this can lead to infection through saliva.
Physical contact with an infected person.
Oral (HHV is also found in saliva) way.

It is necessary to know how this disease is transmitted in order to have time to prevent its occurrence in yourself and your relatives or, in case of infection, to prevent the infection from starting.

Diagnostics

Only an experienced specialist can make an accurate diagnosis indicating herpes in the body. There are several laboratory methods for detecting this disease:

ELISA (enzymatic immunoassay)

It is one of the most expensive and complex analyzes. Nevertheless, thanks to it, it is possible, by the presence of titers of two types of antibodies igm and igg, to judge the presence of the disease and identify the DNA of the herpes virus, as well as diagnose the presence of immunity to it (whether primary infection or repeated - relapse).

The titers of igm antibodies indicate the primary infection of the organism; credits igg - about the second. If no antibodies are found in the body, this is proof that the person is absolutely healthy.

PCR (polymerase chain reaction)

The study of the main set of biological fluids of the human body to identify the DNA of viruses, including HHV.

Complete virological analysis

It occurs by seeding cells isolated from the patient's body on a nutrient medium containing herpes strains.

Based on the observed development of cells and the virus itself, as well as igg indicators, one can conclude that this disease is present, as well as determine its type.

Despite the rather large possibilities of medicine, the appointment of tests for the presence of HHV in the body is not always advisable. If the patient's disease progresses in enough mild stage, then there is no need to take him for examination, because most likely it will pass by itself even before the results of the analysis come.

Treatment

It is worth noting that the treatment of type 6 herpes will not completely destroy this virus in the body. But, nevertheless, the treatment of type 6 herpes in adults and children includes taking the following drugs that inhibit the activity of microbes:

Antiherpes drugs - the most active effect on HHV-6 of the drug brivudine was noted. In addition, doctors ask patients to pay attention to the fact that acyclovir cannot be used to treat type 6 herpes, and the drug foscarnet has many side effects.

Immunoglobulins are drugs that contain an active protein that acts as a stimulator of the human immune system. Antiherpes immunoglobulins include amixin, polyoxidonium. However, the greatest efficiency was noted with the use of herpimun 6.

Interferons are drugs aimed at increasing immunity. A necessary tool, due to the fact that a weakened body stimulates the development of the virus. The most common are Derinat and Panavir. With a significant weakening of the body, in case of ineffectiveness of the drugs considered, the doctor prescribes a special antiviral vaccination.

Vitamins - during the period of weakening the protective properties of the body, it is necessary to supply it with individual vitamins, such as A, C, E. Taking vitamin complexes is allowed.
Antiviral medicines- drugs. aimed specifically at suppressing the virus.
To combat the herpes virus 6 subtype A, the drug foscarnet is most often used.
Treatment of subtype B requires the drug ganciclovir. It is important to remember that taking antiviral drugs is possible only according to the doctor's instructions. Children under 12 years of age are strictly prohibited from using them.
In addition, in a serious condition of the patient, it is possible to take antipyretics such as nurofen, ibuprofen and others.

Treatment of children according to Komarovsky

Yevgeny Komarovsky developed his own method of how to treat herpes. According to his principle, the treatment of type 6 herpes in children includes:

quarantine - isolating the child from contact with peers, as well as, if possible, with family members for seven days;
antibiotic treatment, as well as taking anti-inflammatory drugs;
after quarantine, the child can safely attend kindergarten or other educational institutions, freely contacting people around him.

This method is also widely used in the treatment chickenpox in young years.

Prevention of HHV-6

To prevent the development of the herpes virus of the 6th variety in yourself or your child, the prevention of this disease will help, because the infection is a consequence of a weakened immune system. It is necessary to carry out activities aimed at strengthening it. These include:

Proper and balanced eating - it is useful to include more fruits and vegetables in your menu, this is especially important in the autumn-winter period.
Newborn babies need breast-feeding, because exactly mother's milk contains the full composition of the nutrients necessary for the development of the body, which in the future will have a beneficial effect on immunity.
Active life - physical activity strengthens the body, preventing the development of viruses or other diseases.
The correct mode of the day - there should be a clear separation between work and rest. Each person must find a daily regimen in which his body will be most comfortable. In no case should you forget about a full sleep.
Taking vitamins - in winter it is quite difficult to include fresh fruits and vegetables in your diet. In this regard, the supply of the body with useful vitamins and elements practically stops. To maintain your health, you need to take vitamin complexes (Vitrum, Alphabet), which can significantly strengthen the body. But, it is worth considering that before you start taking any drugs, you need to consult a specialist.

Thus, although HHV-6 is incurable and difficult to diagnose, its occurrence can be avoided through careful health care. If the first symptoms are observed in an adult or a child, then an immediate appeal to a specialist is necessary to further determine the therapeutic measures.

Mankind knows 8 types of herpetic infection. The most common are herpes simplex viruses (HSV). Statistics show that the frequency of infection with this disease prevails even over SARS. What is the difference and how does herpesvirus type 6 manifest itself?

Peculiarities

Herpes type 6 is a DNA-containing infectious virus of a spherical shape with 30 structural proteins of the Herpesviridae family. It was discovered in 1986 by biochemists from the USA in the process of monitoring patients with lymphoreticular pathology. There are two types of the virus: type A and B.
The first subtype is diagnosed extremely rarely. The risk group includes people with severely weakened immunity against the background of progressive HIV infection, hemoblastosis, pathological changes central nervous system. This disease occurs regardless of age.

As for the second subtype of this herpesvirus, it is more common. The infection is present in the blood of almost every person. For a long time, it can "sleep", and when provoking factors (hepatitis, pneumonia, etc.) occur, it is activated and manifests itself with characteristic symptoms. Children in the first years of life are mainly affected by the virus, they are often diagnosed with sudden exanthema.

As a result of infection with the herpes virus type 6, a protective stable immunoglobulin is produced, which remains in the body throughout life. Statistics show that almost 100% of the total population in adulthood have antibodies against the described herpevirus.

Risk groups for HHV 6 (herpesvirus 6):

pregnant,
premature babies,
newborns,
people over 65,
blood recipients,
carriers of HIV in the AIDS stage,
patients undergoing radiation therapy
people who have promiscuous sex.

An important aspect of the manifestation of the virus is its ability to disguise itself as other diseases, therefore clinical picture looks varied. Herpes type 6 in adults is accompanied by symptoms characteristic of diseases such as pneumonia, influenza, tonsillitis.

Typical symptoms and signs of infection

In the older age group, there are complaints of weakness, headaches, fever up to 390C, swollen lymph nodes, redness of the throat, pharynx, rash on the body, exacerbation of chronic and past nosologies, pain in muscles and joints. Syndrome manifests itself chronic fatigue with overwork and disturbed sleep, as a result of which a person becomes more irritable, emotionally unstable.

V childhood in the presence of the described infection, a characteristic small rash forms, covering the entire body. Its predecessor is a sharp increase in body temperature, inactivity, irritability. The rashes do not cause severe itching, disappear after a few days. Often, pediatricians mistake type 6 herpes virus in children for rubella, measles, otitis media, meningitis, and bacterial pneumonia.

The course of the disease in children

Symptoms of herpes type 6 are manifested in children with a disease called sudden exanthema (syn. baby roseola), which is one of the most common childhood diseases. Mostly babies from 8 months to one and a half years old are sick, and by the age of 5, almost 100% of children have antibodies to the virus in their blood.

The incubation period is 3-7 days, sometimes it lasts up to 17 days. The herpes virus type 6 begins in a child with a high temperature, reaching 39-40 0C, agitation, insomnia, lack of appetite, sometimes liquid stool. In some cases, febrile convulsions progress. On the 4-6th day, the fever disappears and after 10-20 hours, in 25% of cases, skin rashes appear in the form of pale pink spots with a diameter of 2-5 mm.

Localization of the rash:

abdominal area,
back,
breast,
elbows,
knees,
person, but in rare cases.

After 2-3 days the rash disappears. In most cases, the disease resolves on its own, does not require treatment and ends without complications, but cases of a manifest course have been established. Sometimes HHV type 6 is asymptomatic, mild, or accompanied by signs of a common ARVI. Parents do not even suspect that the child was infected and successfully survived the disease, but the temporary rash that appears is often attributed to an allergic reaction caused by medication.

Causes and ways of transmission

This virus, along with EBV infection and other herpes viruses, is very widespread among all population groups. The carrier is both a patient with an acute, erased or latent form of the disease, and a healthy person-carrier. The disease can be transmitted from a woman to a child during childbirth, tactile contact, kissing. Often, HHV infection occurs due to the use of non-sterile instruments in medical facilities.

Methods of transmission of infection:

airborne,
contact household,
parenteral (diagnostic, therapeutic manipulations),
transplacental,
sexual.

You can become infected through saliva, sputum, mucus, tears, urine, the contents of vesicles (blisters that appear in an infected person), blood, personal hygiene, children's toys.

Modern diagnostic methods

The presence of herpes type 6 is determined using special diagnostic methods. In particular, these are:

examination of biomaterial under a microscope,
the binding reaction of antibodies to the antigen of the virus,
the procedure for isolating the causative agent of infection on special cultures,
genetic research.

The diagnostic criteria are the identification of Tzank giant cells and Unn cells. The role of the simultaneous use of several methods of examination is also important.

To determine the activity of the process, the presence of relapses, the chronic stage of the disease, it is important to conduct a simultaneous complex of laboratory tests to detect negative or positive immunoglobulins, and assess the immune status. Diagnostic process:

The immunofluorescent diagnostic method is based on the determination of the described virus in the blood. If its concentration is high, the results will be most accurate. The procedure consists in mixing the obtained blood with antibodies and laboratory special dyes for subsequent examination under a microscope. The activated virus reacts and begins to glow, which can be detected during the study.
PCR is a sensitive reaction, during which DNA of the virus of interest is detected in the examined material. The mechanism consists in repeated stopping of a certain gene, which makes it possible to determine the type of pathogen, its qualitative and quantitative indicators as accurately as possible.
Enzyme-linked immunosorbent assay (ELISA) is a reaction in which the antigen-antibody complex is released. In this case, the herpetic virus acts as an antigen, a foreign component for the human body, upon reaction with which the immune system produces antibodies (Ig or immunoglobulins). These protective antibodies with the blood stream enter the site of infection and suppress it. When conducting an analysis for herpes, the following classes of immunoglobulins are distinguished:

IgM– refer to the first antibodies that are found in the blood within 2 weeks after infection,

IgG- antibodies indicating the presence of the described virus in the body for a long time. If there is a relapse of the disease, the amount of antibodies produced increases dramatically.

cultural method. Its essence is based on the initial isolation of the virus from the biomaterial for subsequent infection of special biological objects in the laboratory. Such a study is more often applicable for scientific purposes, takes a lot of time and requires impressive costs.

Diseases associated with HHV type 6

The described pathology is accompanied by extensive symptoms. Statistics show that the primary infection in the vast majority of cases occurs in early childhood in the form of roseola. The virus, when it enters the body, reduces the immune response and occasionally leads to the development of concomitant diseases:

chronic fatigue syndrome,
necrotizing lymphadenitis (inflammation of the lymph nodes, leading to their necrotic destruction),
CNS disorders - meningitis, encephalitis, multiple sclerosis,
mononucleosis unrelated to Epstein-Barr virus infection.

The described herpesvirus affects the course of pathologies of the upper respiratory tract such as acute and chronic tonsillitis, rhinosinusitis. The role of type 6 herpes in the onset of chronic fatigue syndrome is discussed by many authors of scientific papers.

Big and small diagnostic criteria last:

Unexplained, constant fatigue, not associated with physical or mental labor.
Exclusion of other causes of CFS.
High temperature up to 38 0С, pain and perspiration in the oral cavity.
Moderate enlargement of peripheral lymph nodes.
Violation of night sleep.
Agitation, unclear consciousness, decreased attention.
Decrease in the level of professional, educational activity.

The diagnosis of CFS associated with herpes type 6 is established by a neurologist in the presence of major and minor criteria. Treatment of HHV-6 involves the use of several types of drugs:

Antiviral medicines. A prime example is Acyclovir, which effective action against viruses of the herpes group. Immunoglobulins that contribute to the production of specific antibodies when an infection enters the body.
Interferons.
Immunomodulators maintain the normal protective function of the body, prevent re-infection with HHV.
Antipyretic drugs are applicable when too high temperature accompanying herpevirus 6.
Reception of complex multivitamins.

The indicated medicines are taken after a preliminary examination by a specialist. The doctor prescribes individual therapy, selects the optimal medications that will help to adequately treat the patient and eliminate the accompanying symptoms. If bacterial infections develop in parallel, antibiotics are prescribed to the patient.

Complications of herpes virus infection

HHV 6 is not deadly, but occasionally, when it enters the body, it provokes the following complications:

sclerosis,
meningoencephalitis,
myocarditis,
autoimmune diseases,
retrobulbar neuritis,
angina,
liver failure,
epileptic seizures,
cancerous neoplasms in the form of lymphoma, leukemia, brain tumor.

It is difficult to prove that the above diseases are caused by HHV 6. With timely treatment to the clinic and adequate therapy, complications can be avoided.

Prevention of infection with herpes

The high susceptibility of the population to the described infection makes effective preventive measures difficult. Only social isolation will help prevent infection with the “sixth” type virus, so meeting with it is almost inevitable. In such a situation, the emphasis should be on preventing severe variants of the course of the infection and the development of its complications.

It is important to take measures to increase overall immunity, try to keep breastfeeding up to a year, adhere to a rational and balanced diet.

Vitamin therapy, the use of local antiseptics and barrier contraceptives can also help. A personal measure of prevention will be an attentive attitude to your health and maintaining it at the highest level. Should be abandoned bad habits(smoking, drinking), observe a normal activity regimen and get enough sleep. It is important to avoid stressful situations that negatively affect overall well-being and the functioning of the immune system.

The herpes virus is in the body of almost every person, and up to a certain point, the immune system successfully copes with it. Under the influence of various factors and with a decrease in the body's defenses, pathology is accompanied by the appearance of pronounced symptoms.

In children, immunity has not yet fully formed, so children are especially susceptible to pathogens of various types. Most often, type 6 herpes virus is diagnosed in children, which affects lymphocytes. It is resistant to drugs and has 2 types.

The mechanism of action of the herpes virus type 6

A characteristic difference of the herpes simplex virus type 6 is the presence of a dense shell with receptors. Their main constituent element is the CD46 protein, which is localized on the cell surface. It is for this reason that the virus settles in the body in a short time.

Having entered the body, the pathogen tries to get into CD4+ cells, which are gradually converted into T-lymphocytes that can suppress immune responses. Due to this property, the viruses induce the phenotype of T-lymphocytes and combine with the CD46 protein.

Types of herpes type 6

The herpes virus type 6 is divided into two subtypes that differ in DNA and clinical manifestations.

Today, the most neurovirulent is herpes type 6, which is mainly diagnosed in patients with pathologies of nerve fibers, among which the most common is multiple atherosclerosis. The development of such an ailment has nothing to do with the age of the patient, and sometimes it is diagnosed even in infants. main reason The development of multiple sclerosis is considered to be infection with herpes 6A of the nerve tissues of the spinal cord and brain. Medical practice shows that often the herpes virus 6A is diagnosed in people with HIV.

Herpes of type 6 group B has been more widely studied by specialists and it is believed that it causes such a pathology as baby roseola. Having penetrated into the body, viruses begin to react with immune factors, and, having got into the epidermis along with the blood, destroy tissues. A characteristic manifestation of such an ailment is the rise of the body in the absence of any signs of a cold. With such a pathology, the lymph nodes increase, and on the 3-4th day a red rash forms, which gradually spreads to other areas.

Features of herpes type 6 in children

With type 6 herpes in children, the symptoms and treatment are determined by the type of pathogen and the individual characteristics of the organism. Most often, the virus enters the body of a child in infancy, starting from the 3rd month of his life. It is during this period that antibodies received from the mother stop working in the body. A small number of children are infected at birth, this happens if the mother has caught the virus in the last weeks of pregnancy.

In the event that the infection lives in the body of the parents, then they can infect the child directly by contact with him. The most common way of infection is considered to be airborne, and its transmission from breast milk impossible.

Symptoms

In children, the infection often occurs in the form of roseola and fever. Both of these pathologies are accompanied by a rise in temperature up to 40 degrees, severe chills and constant weakness.

The course of roseola is accompanied by the appearance of the following symptoms:

an increase in regional lymph nodes and their soreness;
rhinitis and nasal congestion;
pain in the abdomen;
upset stool and vomiting;
loss of appetite or its complete absence;
sleep problems;
damage to the conjunctiva of the organs of vision;
rashes on the skin;
swelling of the tonsils and throat.

When the temperature rises and the nervous system is damaged, epileptic seizures and other disorders may appear. The child's immunity is greatly reduced and under the influence of infection, the development of sepsis and pneumonia is possible.

The main symptom of the herpes virus type 6 in children is a rash on the body. It usually occurs after a decrease in temperature, does not cause any pain and does not itch.

When the infection of the throat mucosa is affected, they speak of a pathology such as mononucleosis.

It is characterized by the appearance of the following symptoms:

rise in temperature;
pain when swallowing;
swelling of the mucous membrane of the throat;
enlarged lymph nodes and their soreness;
pain in the abdomen and diarrhea;
body intoxication.

Medical practice shows that it is quite difficult to establish the cause of the pathology and diagnose the pathogen. It is for this reason that the prescribed therapy often turns out to be incorrect, which worsens the patient's condition.

How is herpes type 6 diagnosed?

In the case of primary infection, it is quite problematic to identify and recognize the virus. It is even more difficult to determine it during the inactive stage, and do this with the help of laboratory research. Sometimes doctors mistake the symptoms of the herpes virus for manifestations of other diseases.

To determine the exact type of pathogen in the body, the following studies are usually carried out:

PCR diagnostics helps to identify the virus in the body, and determine its type through DNA.
ELISA makes it possible to recognize the virus within a week after it enters the body, even before the development of the clinical picture.
The cultural method helps to establish the presence of the herpes virus in the blood long before the rash on the body.

Treatment Methods

To date, it is problematic to completely get rid of the herpetic virus of any type. The main focus is on preventing relapses and keeping the virus inactive. The choice of one or another method of therapy is determined clinical manifestations pathology.

For the treatment of herpes virus type 6, certain groups of drugs can be selected:

Immunomodulators help to support and raise the body's defense mechanisms. Most often, medications such as Kipferon, Neovir and are prescribed.
Antipyretics are intended for systematic therapy. To their help, in case of exacerbation viral infection, are resorted to when the temperature rises and the need to reduce it.
Immunoglobulins are mainly selected against the herpes virus type 6, and Amiksin, Likopid and Gerpimun 6 are considered the most effective.

To increase immunity can be selected vitamin complexes containing vitamins A, E and C.

Antivirals

It is necessary to start therapy for herpes type 6 in adults and children immediately after diagnosis. Complex treatment involves the usual use of antiviral drugs that suppress the activity of the virus and completely destroy it. Children are usually selected drugs based on, since they are highly effective in combating such a pathogen.

The course of therapy lasts at least 5 days, but with severe course pathology treatment can last 10-14 days.

Consequences and complications

The danger of the herpes virus type 6 for a child is that such a pathology causes an increase in body temperature. Against the background of such a course of the disease, severe febrile convulsions and malfunctions in the functioning of the nervous system may appear.

Often, this form of the virus provokes the development of such complications in the body as damage to the lungs and membranes of the heart, as well as encephalitis and meningitis. In the event that in children's body gets 6 and herpetic infection, then the consequence of this condition may be mental retardation and deviations in the psycho-emotional state.

Herpes virus type 6 poses a threat to infants with congenital or acquired immunodeficiency. With such a pathological condition, the state of the immune system worsens, other infections join, and death is possible. In such a situation, treatment is carried out with the use of potent stimulants.

Prevention

In fact, even the most thorough therapy does not guarantee that the child's body will not encounter the virus. With type 6 of the herpes virus, strong immunity is developed in the body, and with its normal operation and the absence of relapses of chronic pathologies, the development of infection is completely excluded.

Prevention of type 6 herpes infection includes some activities:

avoid contact of the child with colds;
increase the immunity of the child;
during epidemics, avoid hypothermia of the body;
timely eliminate any signs of colds.

The success of therapy for herpes type 6 in childhood is determined by how the parents respond to the infection in a timely manner. At the same time, the herpes virus type 6 does not always require effective treatment. The fact is that it rarely provokes serious complications. When type 6 herpes is detected, you can find out what it is and what complications such an infection can cause.

Herpesviruses (Herpesviridae) is a large family of DNA-containing viruses that cause a variety of diseases in humans and other mammals.

Most of the population of our planet is infected with herpesviruses. There are 8 members of the herpesvirus family that infect humans. One of them is the human herpes virus type 6 ( HHV-6). According to international classification HHV-6 is a DNA virus of the subfamily Betaherpesvirinae of the genus Roseolovirus. This virus is ubiquitous. HHV-6 is the common collective name for the human herpesvirus 6A and 6B serotypes.

Presumably strains HHV-6A are neurovirulent. HHV-6B are more often isolated from patients with lymphoproliferative and immunosuppressive diseases. Antibodies to HHV-6 found in most (up to 90%) people. At birth, most children are seropositive due to maternal antibodies, the titer of which decreases by 5 months. However, by one year of age, the ratio of seropositive to seronegative children is the same as in older children and adults. Maternal antibodies protect against infection HHV-6 in the first months of life, but after a decrease in their titer, infection may manifest itself, for example, as a sudden exanthema.

The virus is in the human body salivary glands and nasopharyngeal mucus, in the latent phase is stored in monocytes/macrophages. Under natural conditions, the main route of transmission of the virus is airborne. In most cases, infection occurs postnatally. Infection is possible during blood transfusions, organ transplantation, when using medical instruments contaminated with the virus.

Diseases associated with primary acute HHV-6 infection: chronic fatigue syndrome, sudden exanthema in newborns and children, infectious mononucleosis in adolescents and adults, not associated with Epstein-Barr virus infection, histiocytic necrotizing lymphadenitis. Primary HHV-6 infections in adults are rare, since infection mainly occurs in childhood from 4 months. up to 3 years. The disease is characterized by an acute onset - the temperature often rises to 39 °, in the following days moderate intoxication is observed. On the fourth day, the temperature drops, almost simultaneously, signs of a rash appear in the form of pale pink discrete elements 2-5 mm in diameter. Most often, rashes appear on the back, subsequently moving to the chest and abdomen, to the extensor surfaces of the arms and legs. After 2-3 days, the rash disappears, leaving mostly no traces. Peripheral blood studies show the presence of neutropenia, leukopenia, monocytosis, and relative lymphocytosis.

Diseases associated with persistent HHV-6 infection: lymphoproliferative diseases (lymphadenopathy, polyclonal lymphoproliferation), malignant lymphomas (non-Hodgkin's lymphoma, peripheral T-cell leukemia, B-cell lymphoma, dermatopathic lymphadenopathy, lymphogranulomatosis. HHV-6B can be considered as a co-factor of diseases such as multiple sclerosis, chronic fatigue syndrome, fibromyalgia, AIDS, optic neuritis. Recent studies have shown a potential role HHV-6(possibly option A) in the development of chronic Hashimoto's thyroiditis.

Diagnosis of infection caused by human herpesvirus type 6 is based on the use of immunological methods and the detection of the virus in media by PCR.

From the point of view of a practical physician, the relevance of detecting the herpes virus type 6 in patient media is determined not so much by the direct action of the virus as by its ability, in association with other viral or bacterial infections, to significantly aggravate their course.

For example, chronic cystitis caused by E. Coli (urine culture 103-104 CFU) in association with HHV-6 detected in the urine, may recur for several months, despite adequate antibacterial urological treatment. There were 5 such patients under our supervision.

Long-term recurrent respiratory infections in adults and children are often associated with the association of "common" infections (adenoviruses, rhinoviruses, coccal flora) and herpesvirus type 6. Under our supervision there were 27 patients aged 3 to 35 years who complained of frequent (more than 15 times a year) diseases of the nasopharynx. In 19 of them during PCR analysis of saliva was isolated HHV-6 virus. In 2 patients, together with HHV-6 EBV was also isolated, one had an isolated CMV infection, and 3 had an isolated EBV infection.

The effectiveness of targeted blood autonosodes for the treatment of chronic viral hepatitis B and G was shown in our report at last year's conference. In this work, we investigated the effectiveness of using direct targeted salivary nosodes and inverse targeted urinary nosodes for the treatment of viral and bacterial infections associated with HHV-6.

For treatment, a direct autonosode was made from the patient's saliva using the IMEDIS software and was targeted according to the Kuprum D400 optimality criterion. In addition, each patient received their constitutional preparation in a low dilution. Patients who did not have any viruses isolated in saliva received the usual bioresonance and homeopathic treatment. After 5 weeks, a control analysis of saliva by PCR was performed to determine the previously identified virus. In 16 out of 19 patients, the virus HHV-6 has not been highlighted. EBV was isolated from one patient. Pronounced regression of clinical symptoms was observed in 24 out of 27 patients.

During treatment chronic cystitis an inverse urine autonosode aimed at Cuprum D400 and PBR with an inductor on the area was used Bladder. All 5 patients managed to achieve regression of clinical symptoms and cessation of virus isolation within a month. Follow-up of more than 6 months.

Conclusions:

Persistent HHV-6 infection can significantly aggravate the course of other viral and bacterial infections.
Targeted autonosodes of saliva or urine are effective drugs, for treatment chronic diseases associated with HHV-6, and possibly EBV and CMV infections.
