Infectious mononucleosis in children – symptoms,treatment, complications

Update: December 2018

A disease called infectious mononucleosis was first
described N.F. Filatov in 1885 and became known as
idiopathic lymphadenitis. it острое инфекционное вирусное
a disease that is characterized by an increase in the size of the spleen
and liver, white blood change and disorder
reticuloendothelial system complicated by lymphadenopathy.

It has been established that this disease causes a particular herpetic virus.
Epstein-Barr (4 types), affecting the lymphoid-reticular
the cloth. When it enters the body by airborne droplets it affects
the epithelium of the oropharynx, then with blood and regional lymph nodes.
Epstein-Barr virus remains in the human body for life, and
with a decrease in immunity can periodically recur.

Причины инфекционного mononucleosis у детей

Most of all, children under 10 are predisposed to this disease.
years old. As a rule, the child is often in a closed team,
for example, in kindergarten or in a school where transmission is possible
by airborne droplets. The virus dies very quickly when hit
into the environment, therefore contamination occurs only when close
contacts, so it can not be called very contagious. Virus
Epstein-Barr in a sick person is in particles of saliva,
therefore, infectious mononucleosis can be transmitted from person to person.

  • kiss
  • coughing
  • sneeze
  • use of common utensils

It is noteworthy that boys suffer from infectious mononucleosis in
two times more often than girls. Thus, there is a possibility of easy

period. Some people do not experience any symptoms.
diseases, however, are virus carriers and represent
potential danger to others. Virus проникает в организм
through the respiratory tract, and the incubation period of the disease is
about 5-15 days. In some cases, it can last up to one and a half
months.

Virus Эпштейна-Барр очень распространенная инфекция, до
At 5 years of age, over 50% of children become infected with this type and

Moreover, the infection of the adult population according to various data
is 85-90% and only in some children or adults is this
the virus is expressed by symptoms called infectious
mononucleosis.

Since today there is practically no infection from viruses.

baby in the next 2-3 months. Если симптомов mononucleosis не
will appear, therefore, either the child is infected, or immunity
coped with the virus and the infection passed safely.

If the child has symptoms of general intoxication – chills,
fever, weakness, rash, swollen lymph nodes – to
which doctor to contact? First to the district pediatrician or
to the family doctor, then to the infectious disease specialist.

Инфекционный мононуклеоз у детей

Симптомы инфекционного mononucleosis разнообразны. Sometimes
common phenomena of a prodromal nature, such as
malaise, weakness and catarrhal symptoms. Gradually
the state of health worsens, the temperature rises to subfebrile,
there is constant sore throat and difficulty breathing
due to nasal congestion. A characteristic phenomenon can also be called
hyperemia of the mucous membrane of the oropharynx, as well as pathological
overgrowth of tonsils.

Sometimes заболевание начинается внезапно, и его симптомы ярко
are expressed. In this situation, it is not excluded:

  • fever, it proceeds differently (usually 38 -39C) and
    lasts a few days or even a month
  • increased sweating, chills, drowsiness, weakness
  • signs of intoxication – headache, aching muscles and
    pain when swallowing

Then comes the culmination of the disease, that is, manifest
the main features of the clinical picture of infectious
mononucleosis, в том числе:

  • sore throat – there is a granularity of the posterior wall of the pharyngeal mucosa,
    her hyperemia, follicular hyperplasia, probably hemorrhage
    mucous
  • hepatosplenomegaly – enlarged liver and spleen
  • lymphadenopathy – lymphadenopathy
  • total body intoxication
  • appearance of a rash on the body

A rash with mononucleosis most often occurs at the onset of the disease,
simultaneously with fever and lymphadenopathy, it can also
be quite intense, localized on the legs, hands, face,
stomach and back in the form of small red or pale pink spots.
The rash does not require treatment, because it does not itch, it can not be anything
smear, it is independently eliminated as the struggle intensifies
immunity with the virus. But, если ребенку назначили антибиотик и
the rash began to itch – this indicates an allergic reaction to
antibiotic (most often it is a penicillin series of antibiotics –
ampicillin, amoxicillin), because the rash in mononucleosis does not
itching

But, наиболее важным симптомом инфекционного mononucleosis,
traditionally considered polyadenitis. It arises as a result.
hyperplasia of lymphoid tissue. In most cases on the tonsils
nasopharynx and palate develop islet overlays of gray or
whitish-yellowish. Their consistency is loose and lumpy,
they are easily removed.

Besides того, увеличиваются периферические лимфатические узлы. AT
they are delayed actively breeding virus. Especially intense
lymph nodes grow on the back of the neck: they become very
noticeable when the child turns his head to the side. Beside
located lymph nodes are interconnected, and almost always their
the lesion is bilateral in nature.

Palpation of the lymph nodes is not very painful, they are mobile
and not tightly in contact with the skin. Sometimes увеличиваются и лимфоузлы,

this area and provoke the occurrence of signs of acute abdomen.

Для инфекционного mononucleosis характерна гепатоспленомегалия,
that is, a pathological enlargement of the spleen and liver. These bodies
very sensitive to the disease, so changes in them begin
occur in the first days after infection. Spleen can
increase so much that its tissues do not withstand pressure, and she
torn.

The first 2-4 weeks there is a continuous increase in the size of these
organs, to some extent it continues after recovery
baby When body temperature returns to physiological
values, normalization of the state of the spleen and
the liver.

Diagnosis of the disease

Для начала, чтобы подтвердить диагноз инфекционного mononucleosis
in a child, the doctor usually prescribes the following tests:

  • Blood test for antibodies IgM, IgG to Epstein-Barr virus
  • General and biochemical blood test
  • Ultrasound of the internal organs, especially the liver and
    spleen

difficult. The main signs of the development of the disease is considered
tonsillitis, enlarged lymph nodes, liver and spleen,
fever. Eye doctor can not determine a sore throat in a child or
infectious mononucleosis, therefore serological
research. Hematologic changes serve as a secondary symptom.
инфекционного mononucleosis.

Анализ крови при мононуклеозе у children:

  • According to the results of the general blood test can be judged by the number
    leukocytes, lymphocytes and monocytes.
  • ESR is also increased.
  • Of course, the indicator of the presence of atypical
    mononuclear cells – cells with large basophilic cytoplasm. ABOUT
    развитии инфекционного mononucleosis говорит увеличение их
    content in the blood up to 10%. It should be borne in mind that atypical
    elements do not appear in the blood immediately, and sometimes only after 2-3
    weeks after infection. Atypical mononuclear cells are
    oval or round elements whose size can reach to
    sizes of large monocyte. These atypical elements are also called
    �”Monolymphocytes” or “wide plasma lymphocytes”.

When differentiating the diagnosis, first of all, you need to distinguish
tonsillitis from sore throat, eliminate Botkin’s disease, acute leukemia,
lymphogranulomatosis and pharyngeal diphtheria, which have similar symptoms.
For the most accurate diagnosis in difficult cases, analyze
determination of antibody titer to a specific Epstein-Barr virus.
There are also fast modern laboratory techniques.
studies that allow you to get results through
as short as possible, for example PCR.

Persons with infectious mononucleosis undergo
several serological studies conducted every few
месяцев, на предмет определения наличия ATИЧ-инфекции, поскольку она
also provokes high blood levels of mononuclears.

Also, if you experience symptoms of angina, you should visit
otolaryngologist and pharyngoscopy to correctly identify
the cause of this disease, since it can be different
etiology.

How not to get infected from a sick child to adults and others
children?

If the family has a child or an adult who is sick
infectious mononucleosis, do not get infected with the rest of the family
It will be difficult enough, not because the virus is very contagious, but
because even after recovery, the ill child or
An adult may periodically excrete a virus with particles of saliva in
environment and remains a virus carrier for life.

Therefore, the need for quarantine with infectious mononucleosis
нет,  даже если здоровые члены семьи в период болезни ребенка
for sure, infection will occur later, during
when the patient has already recovered and will return to normal routine
of life. With a slight course of the disease, it is not necessary to isolate
child and set quarantine, he can return to school as
just get better.

How to treat infectious mononucleosis in children

To date, there is no specific treatment for infectious diseases.

an antiviral drug that would effectively suppress
virus activity. ABOUTбычно заболевание лечится в домашних conditions
in severe cases in the inpatient setting and recommended
only bed rest.

Clinical indications for hospitalization:

  • High temperature 39, 5 and above
  • severe symptoms of intoxication
  • development of complications
  • threat of asphyxia

There are several ways to treat mononucleosis in
children:

  • Therapy is mainly aimed at relieving the symptoms of infectious
    mononucleosis
  • Pathogenetic therapy in the form of antipyretics for
    children (ibuprofen, paracetamol in syrup)
  • Antiseptic local preparations for the relief of angina, and
    also as a local non-specific immunotherapy, prescribed
    drugs Imudon and IRS 19.
  • Desensitizing agents
  • Restorative therapy – vitamin therapy, including vitamins
    groups B, C and R.
  • If changes in liver function are detected, a special
    diet, choleretic drugs, hepatoprotectors
  • Immunomodulators in conjunction with antiviral drugs
    have the greatest effect. Imudon, Child may be appointed.
    Anaferon, Viferon, and Cycloferon at a dose of 6-10 mg / kg. Sometimes
    has a positive effect metronidazole (Trichopol,
    Flagyl).
  • Since the secondary microbial flora does not rarely join,
    antibiotics that are prescribed only in case of complications are shown
    and intense inflammation in the oropharynx (except
    antibiotics of the penicillin series, which are precisely in infectious
    mononucleosis in 70% of cases cause severe allergic
    reaction)
  • When antibiotic therapy is prescribed at the same time probiotics
    (Acipol, Narine, Primadophilus Children, etc., see the entire list
    probiotics with prices and composition)
  • In case of severe hypertoxic course, a short-term
    course of prednisolone (20-60 mg per day for 5-7 days), he
    used at risk of asphyxiation
  • Installation of tracheostoma and transfer to artificial ventilation
    the lung is carried out with a strong swelling of the larynx and with difficulties with
    breathing in children
  • When the spleen ruptures, an emergency procedure is performed.
    splenectomy.

Прогноз и последствия mononucleosis

Infectious mononucleosis in children usually has a fairly
favorable prognosis. However, the main condition for the absence
consequences and complications is timely diagnosis
leukemia and regular monitoring of changes in the composition of the blood. Besides
In addition, it is very important to monitor the condition of children until their final
recovery.

In one clinical study that was conducted with

who have suffered mononucleosis, attended by 150 people. Within half a year
after the transfer of the virus, the patients were watched by doctors,

  • Normally, if the body temperature in infectious mononucleosis
    above 37.5 lasts the first few weeks from the start

    can be considered normal.
  • Angina with infectious mononucleosis or sore throat lasts
    1-2 weeks on average
  • Lymph nodes return to normal in

  • Drowsiness, fatigue, weakness persist after
