Rabies vaccine for cats side effects

Sometimes the Mantoux test, popularly referred to as the "button", is mistakenly considered a vaccination. And when someone intelligibly explains to mothers that what was injected at school, kindergarten or in the treatment room to the offspring in the pen is not a vaccine, but a test, a test, then a lot of questions arise. The well-known pediatrician Yevgeny Komarovsky tells what Mantu is and why such an injection is given.

What it is

The tuberculin test is a diagnostic method, a test for the presence in the body of a microbe that causes tuberculosis - tubercle bacillus. For these purposes, the child is injected subcutaneously with a special drug, which is based on the microenvironment of the causative agent of the disease - tuberculin. Then experts evaluate the body's response to the injected substance. The fact is that people suffering from tuberculosis, infected, and those who are healthy, react diametrically opposite to tuberculin. This reaction is similar to the manifestations of an allergy: if a person has a microbe that causes tuberculosis, tuberculin causes a certain inadequate allergic (immune) response, if the child does not have a bacillus, nothing happens.

Dr. Komarovsky will tell the children in more detail and thoroughly all the questions on the topic of mantoux in the next video.

To date, the Mantoux test is considered an effective diagnostic method all over the world. Alternative ways to find out if a child has TB also exist, but they are few. One of the modern samples - "Diaskintest" is still being introduced. In Russia, the drug is registered and certified completely officially. Its diagnostic action is based on the isolation of some specific antigen proteins that are sensitive only to the aggressive causative agent of tuberculosis. If the usual Mantoux test can give a reaction to the components of the BCG vaccine, then Diaskintest gives a positive reaction only to microbes that are pathogenic. From this point of view, the new test is more perfect. If it is negative, there is no disease; if it is positive, there is a disease.

Why do it

A vaccine aimed at ensuring that the child develops anti-tuberculosis immunity is done even in the maternity hospital. It's called BCG. However, despite vaccination, a child can contract tuberculosis, although the vaccine significantly reduces this likelihood. This is due to the gradual decrease in antibodies to tubercle bacillus. If the baby has not developed immunity at all after the first vaccination, he is given a second one - before school, at the age of 7 years.

In our environment there is always someone who is a carrier of a tuberculosis bacillus, we encounter such people in transport, in a store, on the street, because the policy of the Russian state does not provide for the strict isolation of people with such a diagnosis from society.

Mantoux test should be carried out once a year, starting from the moment when the child is 1 year old. If the test gives a negative result, this is interpreted as the fact that immunity to the tubercle bacillus was not formed after the maternity hospital vaccine, and the doctor has the right to recommend such babies to conduct a tuberculin test not once, but 2 times a year, so as not to "miss" the disease.

It is necessary to make samples according to the existing rules in different hands. If this year the child was done on the left, then in a year it should be done on the right. The place for the introduction of tuberculin is always the same - the inner surface of the forearm, its middle third. If you saw that the test was made in the other third of the forearm, you can not count on the correct result.

Sample Rules

As before vaccination, before the Mantoux test, about a month in advance, you should make sure that the baby feels good. He should be healthy, he should not have any acute diseases and manifestations of allergies. If the child has a fever, it is better to postpone the date of the test to a later date.

You can not do a test if the child has skin diseases, especially during the period of exacerbation, if he has a history of diagnoses " Bronchial Asthma" or "Rheumatism", and also if quarantine is currently declared in the children's team that the child visits. All these are strict contraindications.

After any regular calendar vaccination, a Mantoux test should be carried out no earlier than a month later. Also, more than 30 days must pass after the illness. If you properly prepare for a diagnostic test, then the results are less likely to be false or erroneous.

Is it possible to swim

You can often hear the opinion that a child after a Mantoux test cannot be bathed for 3-4 days. Yevgeny Komarovsky claims that this is not so, and it is absolutely not contraindicated to wash, it is possible to wet the injection site of tuberculin. But there are still a number of restrictions and prohibitions regarding that very “button”:

• The injection site of tuberculin should not be intensively scratched and rubbed (including with a washcloth).
• The injection site is strictly forbidden to lubricate with antiseptics, iodine, as well as ointments.
• On the Mantoux test, you can not stick a plaster, tie a bandage, make compresses and lotions.
• The child should not be dressed in long-sleeved clothing that is not appropriate for the weather, as the release of sweat and friction of the fabric against the sample site can cause a pronounced positive erroneous reaction.

Sample results

A qualified medical professional should evaluate the body's response to tuberculin. However, mothers are usually eager to figure out the intricacies of diagnosis on their own. Their desire is quite understandable and understandable, says Yevgeny Komarovsky. Especially for moms and dads, he explains what the Mantoux reaction can tell.

Accounting is carried out 72 hours after the test. Therefore, the most convenient day for diagnosing is Friday, in most Russian clinics this day is chosen so that the doctor has the opportunity to evaluate the result exactly 72 hours later (on Monday). The place of introduction of tuberculin changes during this time. Sometimes there is redness (hyperemia). Often there is some swelling, an increase in size, induration at the injection site, it is called a papule. The health worker measures not redness, but an enlarged papule, for this they must use a transparent ruler.

The reaction might be:

• negative. If there is any redness, there is no increase in the injection area.
• Doubtful, debatable. If there is redness (hyperemia) or a papule no larger than 2-4 mm. In this situation, the doctor, having assessed the general condition of the child and looked at his medical record, can both equate the result to negative and prescribe additional diagnostic studies.
• Positive. A mild result is determined if the size of the papule is from 5 to 9 mm. The average result - the papule has a size of 10 to 14 mm. A pronounced result is a papule with a diameter of more than 15-16 mm.
• Excessive. The size of the papule with this result is always more than 17 mm. In addition, there is a general reaction of the body - an increase in lymph nodes, the appearance of sores on the skin, signs of an inflammatory process in the papule itself. Such a result in a high degree of probability may indicate developing tuberculosis.

Disturbing results

Sometimes parents are faced with a situation where a sample that was previously always negative is converted into a positive one (and there was no BCG vaccination). In medicine, this phenomenon is called "tuberculin test bend". If it occurs, this may mean that the child has become infected with a tubercle bacillus. Chad will be assigned a consultation with a TB doctor, he will need to take an x-ray of his lungs and undergo additional studies, after which the child will be prescribed treatment.

Infection with a dangerous disease can also be suspected if the Mantoux test, after a positive result (after BCG vaccination), gradually decreased annually, and then suddenly increased sharply (was 5 mm, became 9 mm). Such changes in the size of the papule are also the basis for additional examination and treatment, if necessary.

If for 4-5 years the Mantoux test remains pronounced (more than 12 mm in transverse measurement), this may also indicate the development of pulmonary tuberculosis.

If the parents refuse the test

Recently, a lot of unprofessional and unreliable information has appeared about the dangers of the Mantoux test. So, scary stories about the toxicity of this diagnostic test due to the phenol it contains are “walking” on social networks on the Internet. Therefore, the number of parents who refuse to test their children has increased significantly. Yevgeny Komarovsky claims that the introduction of tuberculin in no way poses any danger to the child.

Phenol as a preservative is indeed contained in the drug, which is administered intradermally, but its amount is very small (about the same amount is contained in 5-6 ml of urine). By the way, phenol is a natural substance for the human body, it is excreted in the urine as a breakdown product of certain compounds. In order for a child to be exposed to the toxic effects of tuberculin, he needs to inject about a thousand doses per day!

Very often, parents have a question whether it is necessary to give the child antihistamines before the test. Yevgeny Komarovsky argues that this cannot be done. Since the main purpose of the Mantoux test is to see if there is an allergic reaction to tuberculin, antihistamines can interfere with this.

The concept of a single "norm" when conducting a tuberculin test in children does not exist.

• Doctor Komarovsky

Traditional medicine first discovered the fact that vaccination is effective. But the possibilities of our ancestors regarding this technique were limited and based on chance. In our time, vaccinations are already used as a full-fledged way of large-scale prevention of infectious, viral and bacterial diseases.

While still in the hospital, the baby is given the BCG vaccine, which helps prevent the development of a complex and deadly type of tuberculosis. When a child turns one year old, he is annually given an immunological Mantoux tuberculin test, which helps to detect the presence of tuberculosis infection in the body.

From childhood, adults remember how some substance was injected under their skin with the help of a special pistol device. After that, a spot appeared at the injection site, which could not be wetted and combed. A few days later, the nurse took measurements of this formation with a ruler, and recorded the results in a journal. This is the Mantoux vaccination.

This research method allows you to evaluate how the human body reacts when antigens of the pathogen enter it. In addition, a tuberculin test is performed to confirm the presence of tuberculosis or to evaluate the effectiveness of ongoing medical therapy.

There are the following body responses to Mantoux in children:

• The absence of any manifestations - redness or subcutaneous compaction. This is a negative result.
• The appearance of a slight redness no larger than 0.5 cm. If the result is doubtful, a second vaccination may be prescribed three months after the first test.
• A reaction is considered positive when a seal and a papule up to 1.5 cm in size form at the injection site, around which the skin turns red.
• If the size of the "button" exceeds 1.5 cm, we are talking about a hyperergic (increased) reaction to the tuberculin test.

The drug used for testing undergoes special cleaning and processing in the laboratory. It is absolutely safe for the health of the child. When administering a vaccine, it is necessary to adhere to the established rules and observe the indicated proportions.

The test results are affected by the presence of certain pathologies in the child's body, non-compliance with the rules for administering the drug, ignoring the conditions for transporting and storing the vaccine.

Rules for conducting an immunological test

Tuberculin testing is done to the child annually. The baby must be over one year old. Each subsequent test is carried out regardless of whether the previous result was positive or negative.

After 3 days from the date of injection of Mantoux, the diameter of the formed “button” is measured. According to the measurements, the exacerbation of the protective function in relation to the Koch's wand is estimated.

It is the size of the papule that is considered indicative. The number of bacteria in the body that cause the development of tuberculosis, and the intensity of the immune response directly affect the size of the "plaque" and increase the likelihood of getting this disease.

A hyperemic area of ​​the skin around the papule does not indicate the presence of a reaction of the body's defense system to tuberculosis or the presence of the disease itself.

Usually the Mantoux reaction is done in clinics, in educational and preschool institutions. Parents do not need to worry that the test will be done without their presence. The procedure is practically painless and not dangerous. The Tuberculin vaccine consists of the waste products of the tuberculosis bacillus, it does not contain the Koch bacillus itself. Therefore, it is impossible to introduce the disease during tuberculin diagnostics.

Adults should ensure that the child does not wet the injection site, does not comb it. You can not lubricate the vaccination with a brilliant green solution or peroxide, and also stick it with a plaster. Such actions may affect the results of the test and give skewed results. After evaluating the reaction, if the wound is inflamed, it can be treated with antiseptic agents.

It is important to know that the tuberculin test does not apply to classical vaccinations, and should be carried out even when the child is exempt from preventive immunization.

If the child's body has responded positively to the tuberculin vaccine, then Dr. Evgeny Komarovsky strongly advises not to panic and conduct an additional examination.

The reaction to the test is not one hundred percent proof that the child will get tuberculosis. No doctor will make a guaranteed diagnosis right away. It is necessary for all children to do the Mantoux test, since the tubercle bacillus is spreading very intensively and the probability of "catching" it is very high.

Contraindications for the test

Tuberculin has been used in medicine for many years. However, its mechanism of action has not been fully understood to date. There are no definitive results of studies of the interaction of the drug with the immune system.

It should be noted that the vaccine does not pose a serious threat to humans (including children), it is effective and expedient. The substance tuberculin does not provoke accidental side effects and does not apply to toxic substances. There are some restrictions for testing for tuberculosis, but there are not many.

Pediatrician Komarovsky draws attention to the fact that the introduction of the drug under the skin to children who are not one year old will not give a true result. The child's body is being formed, and this specificity makes it difficult to establish the correct diagnosis. Also, the accuracy of the Mantoux reaction is affected by the presence of BCG vaccination, so it must be done without fail in the first seven days after the birth of the child.

What are the contraindications for tuberculin diagnostics? These include:

• Skin diseases.
• Rash of allergic origin.
• Bronchial asthma.
• Acute somatic diseases.
• Individual intolerance to the vaccine.
• epileptic seizures.

Contraindications in children include the presence of chronic ailments, acute respiratory diseases. The test should be done only after the complete recovery of the child.

The immunological test does not provoke the appearance of adverse reactions in somatic diseases in children. The dose of tuberculin is so small that it is unable to radically affect the entire body.

After measuring the infiltrate, you can do other vaccinations. Immunization with several vaccines at the same time is not allowed so that one drug does not affect the action of another. If the child has been vaccinated against diphtheria and tetanus, measles and rubella, mumps, then Mantoux can be examined no earlier than 30 days later.

The need for tuberculin diagnostics

The tuberculosis test is one of the most effective to control the number of cases of infection with the Koch bacillus. With the help of the Mantoux test, the following tasks are solved:

• Adults and children who are first infected with the bacillus are identified.
• Patients are identified in whom the infection has been present for more than a year and their immunity responds to tuberculin.
• Tuberculosis is confirmed in people who are affected by Koch's bacillus, but they do not have any symptoms of the disease.
• Children who need to be re-tested (revaccinated) are selected.

To date, the tuberculin test is the only effective method for detecting tuberculosis. But it is worth remembering that if there are contraindications, the Mantoux reaction is not carried out.

Adverse reactions to vaccination

In childhood, a tuberculin test can give the following side effects: allergic reactions, skin problems, constipation. But for some reason, neither pediatricians nor allergists recognize them.

Often the body reacts to tuberculin in the following way: it hurts and dizzy, the temperature may rise, the person has a fever, vomiting spasms appear, rashes of allergic etiology, edema, asthmatic attacks are fixed on the skin, the skin at the injection site begins to itch. There are cases of massive side effects on Mantoux.

Contacting a phthisiatrician

Pediatrician Komarovsky draws the attention of adults to the fact that a child's positive response to the vaccine does not mean that he has tuberculosis. Attentive parents should be wary if:

• After each subsequent vaccination, susceptibility to tuberculin increases.
• The size of the papule has sharply increased during the calendar year (no less than half a centimeter).
• The child was in an area where there is a high probability of contracting tuberculosis.
• The child was in contact with a person who has an open form of the disease.
• There are relatives in the family who have been ill with tuberculosis, or they were once infected.

In the presence of such facts, children should be referred to a TB specialist for consultation. The doctor will determine for what reasons the reaction to the test is positive and establish a diagnosis.

Actions in case of a positive result

If the body reacted to the diagnosis with a plus sign, then the child is prescribed an additional examination, which includes x-rays, a blood test, and bacteriological sputum culture. Family members should also be examined.

The high-risk group for tuberculosis with pronounced symptoms of the disease includes schoolchildren and adolescents. About 10 percent of the children who were first diagnosed with bacillus infection have primary tuberculosis with all the clinical features characteristic of the disease. These children must be registered in a tuberculosis dispensary for at least one year. They are prescribed prophylactic treatment, which lasts three months.

After 12 months, the child is transferred to be observed by the local pediatrician. The patient is listed on the card as "infected for more than a year." Then it is necessary to conduct a repeated test for susceptibility to tuberculin.

In the absence of an increase in the reaction to the test and a hyperergic response, the child continues to be observed by the doctor on the usual basis. It is necessary to carefully monitor the data of the Mantoux test annually. An increasing reaction to the vaccine indicates an exacerbation of the infection.

Children who have been infected for more than one year, and who have a hyperergic reaction, continue to be registered in the tuberculosis dispensary. They belong to the group of patients "infected with an indefinite statute of limitations."

Inactive tuberculosis mycobacteria(Koch sticks). For setting the sample, the inner surface of the forearm is used.

The meaning of the study is that after the introduction of tuberculin, T-lymphocytes interacting with Mycobacterium tuberculosis, this provokes inflammatory response in the skin.

The presence or absence of a reaction to a tuberculous pathogen is assessed by the size of the focus of inflammation.

If there is a reaction, means the organism either infected, or recently vaccinated(BCG vaccine containing mycobacterium "bovine" type). Tuberculin is an allergen, therefore, in an organism predisposed to such reactions it can cause side effects. Before its introduction be aware of the contraindications, and if they are, use alternative diagnostic methods to avoid side effects from Mantoux vaccination.

Have been vaccinated: side effects and complications in a child

Children first encounter the Mantoux test in one year old, since earlier diagnosis is uninformative due to the characteristics of the child's body - increased skin sensitivity of infants.

The result is evaluated after three days after the Mantoux test. A papule (a specific rounded seal) that forms at the injection site of tuberculin can be of various sizes:

1. Missing or having a diameter up to 1 mm- is regarded as a negative result, which means that antibodies to tuberculin have not been developed in the body. In this case, they are vaccinated against tuberculosis (BCG);
2. Papule size from 2 to 4 mm indicates the so-called doubtful reaction. Redness without papule is also interpreted;
3. How positive reactions are deciphered by size, exceeding 0.5 cm, to be more precise:
   • 0.5-0.9 cm- weakly positive;
   • 1.0-1.4 cm- medium positive;
   • 1.5-1.6 cm- strongly positive.

For children, this procedure is carried out annually up to the age of fourteen.

In this case, the norm of the size of the papule differs according to the age of the child:

• at the age of one - from 0.5 to 1 cm;
• at the age of two (this is the peak of the immune response to tuberculin) - 0.8-1.6cm;
• after three years and up to six no more than 1 cm;
• at the age of six or seven, the reaction in almost everyone is negative or doubtful, since by this time the immune response is weakening, children at 7 years old re-vaccinate against tuberculosis;
• after vaccination, the reaction is maximum in the first three years, and then decreases, therefore, for seven to nine-year-old children, the normal size of the papule is 1.0-1.6 cm, For 10-12 year olds — 0,5-0,6 , and aged 13-14 years old the reaction to tuberculin decreases again, so the results of the test are negative or doubtful.

Photo 3. It is against these tuberculosis bacteria that Mantoux is vaccinated.

Adults are diagnosed less often. For this, there must be evidence in the form of contact with tuberculosis patients or the need for repeated anti-tuberculosis vaccination.

In addition, this is how tuberculosis is defined in active form. In adults, this test is quite reliable, since after the age of fourteen practically no one puts Mantoux, which means that the immune response can only be due to infection.

At the same time, the reaction in adults is the same as in children - papules in the place where Mantoux was placed. The sizes of papules with a negative or doubtful reaction are the same, but in the case of infection of the body with a tubercle bacillus, they differ slightly:

• 0.5-1.7cm- the reaction is positive;
• > 2.1 cm- an active disease.

Reaction after Mantoux - consequences in children and adults

Since tuberculin administered for diagnostic purposes is an allergen, the most common side effect is allergy. In addition, the composition of the diagnostic preparation includes phenol as a preservative, which can also cause unwanted reactions after Mantoux:

• itching and pain at the injection site, swelling of the arm;
• rash on the arm where the test was performed;
• weakness and fatigue;
• subfebrile condition (temperature 37 - 38°С);
• heat ( above 38°C);
• anaphylaxis;
• angioedema;
• pustular and inflammatory skin lesions at the injection site.

Photo 5. Mantoux reaction on the skin - a false positive result on the test due to pre-existing diseases of the patient.

To minimize such unpleasant reactions to Mantoux and side effects in children, you should inform the doctor about all the ailments that may be contraindications to the study:

• dermatological ailments: it is in this case that there is a high risk of infection with the introduction of the drug and the development of a purulent-inflammatory disease;
• in general, any disease in an acute form or chronic in the acute stage, since tuberculin can provoke an aggravation of the patient's condition;
• epilepsy;
• research is not carried out within a month after any vaccinations, except for rubella and measles - in these cases, within 1.5 months(otherwise there will be a false positive result) and within a month after quarantine for any disease in organized groups.

Important. Also, to reduce the likelihood of developing adverse reactions to Mantoux in children, it is necessary before the test and before evaluating the results, you should refuse chocolate,coffee, honey,nuts And citrus fruits. If allergic reactions to this procedure have already been observed before, then antihistamines should be taken. three days after the test Mantu.

The child fell ill, became capricious, had diarrhea

Sometimes you can hear from parents that after they made Mantoux, the child got sick. This in no way means that the disease is caused by Koch's wand and the reaction to Mantoux gave complications in children. It’s just that the procedure was carried out at a time when the child was already sick, and the symptoms had not yet manifested themselves, and not the Mantoux vaccination gave such consequences. The same can be said about gastrointestinal disorders in the form of vomiting or diarrhea after Mantoux in a child - here the “culprit” of this condition is not a complication after Mantoux in a child, but incipient disease(most often rotavirus).

Reference. There are frequent complaints from parents that, after the Mantoux vaccination, the child became capricious. This is primarily due to those diseases that already started(asymptomatic) at the time of sampling. And, as already noted, a side effect of the test can be lethargy and weakness, as well as diarrhea in a child, which is why the child will express dissatisfaction with the help of whims.

Large and red papule: should I be worried?

If the child has a reaction to the introduction of tuberculin positive then he will be referred for a consultation phthisiatrician.

false positive the reaction may be with recent infectious diseases, vaccinations, or with an allergic reaction.

This is also a consequence of improper handling of the injection site, because it is not in vain that it is advised not to wet or rub the area where the sample was placed after the introduction of tuberculin.

That is, a big papule at all does not necessarily mean infection mycobacteria and complications after Mantoux in a child and the fact that after they were vaccinated, the child fell ill.

Is different "tuberculous" papule and by coloring - it has clear boundaries and more bright color, moreover, after two weeks, there are no traces of the usual papule, and with tuberculosis, a brown trace remains.

So, the large size of the papule is a reason to visit a phthisiatrician to avoid the consequences of Mantoux in a child. In addition, you will need to pass:

• fluorographic or x-ray examination of the lungs;
• analysis of blood, urine and feces;
• CT (computed tomography);
• ELISA (enzymatic immunoassay);
• PCR (polymerase chain reaction).

Large papule with negative diaskin test

If the Mantoux test is strongly positive, and diaskin test- on the contrary, it is negative, then the reason here is in the different specifics of these diagnostic procedures.

The Mantoux test detects infection with any mycobacteria, including those that are not dangerous to humans, as well as those that are part of the tuberculosis vaccine.

But the diaskin test only reacts to those mycobacteria that cause tuberculosis in humans.

That's why no reaction during diaskin test means with a high degree of probability that tuberculosis in a patient absent. At the same time, the positivity of the Mantoux test here most likely means an immune response due to the previously administered anti-tuberculosis vaccine, and the reaction to Mantoux does not mean complications in children.

In 1890, Robert Koch discovered tuberculin and was sure that this substance would help get rid of tuberculosis, but he was wrong. Nevertheless, his discovery helped create the easiest way to diagnose this terrible disease - the tuberculin test, or, as it is also called, the Mantoux reaction.

Very often, people confuse Mantoux with a vaccine, and this is fundamentally not true. This test has nothing to do with vaccination and is a special diagnostic test necessary to detect the presence of Koch's bacillus in the body.

The test is carried out with the help of intradermal administration of tuberculin and the subsequent assessment of the reaction that has arisen in response to this administration. There are two main types of tuberculin diagnostics:

1. Individual. It is carried out only according to indications;
2. Bulk. This type is carried out for all children at a certain age in countries that are characterized by an increased incidence of the disease.

This study is necessary to identify children who need to be vaccinated, as well as to timely identify those infected.

For the study, two types of tuberculin are used.

1. Alttuberculin (ATK). The so-called tuberculin Koch. Consists of mycobacteria neutralized by heating. Its main disadvantage is that it contains impurities, so the risk of a false positive reaction is quite high. That is why now this type is practically not used in medical practice;
2. Purified tuberculin (PPD). This type of tuberculin is characterized by the fact that it is completely purified from all impurities that could be obtained during the growth of mycobacteria on a nutrient medium.

Is the Mantoux vaccine harmless, what are its contraindications

It is important to understand that the Mantoux test is necessary for the early detection of tuberculosis, so its implementation is of great diagnostic value. Most pediatricians agree that this procedure is completely safe for children. Moreover, both healthy and for children with various chronic diseases.

However, there are contraindications for this procedure:

• acute infectious diseases;
• allergic conditions;
• skin diseases;
• a history of epileptic seizures or a confirmed diagnosis of epilepsy.

In addition, the test is transferred if the child was vaccinated less than a month before it.

Reaction to Mantoux in a child at risk

There are several types of reaction to tuberculin test:

1. Anergy. There is no reaction to the sample (negative);
2. Normergy. There is a moderate reaction;
3. Hyperergy. Insufficient reaction;
4. Hypoergy. Increased response.

It should be noted that third-party factors can influence the severity of the reaction, for example, a decrease in sensitivity to the Mantoux test is observed under the following conditions:

• taking antiallergic drugs;
• a history of recent polio vaccination;
• taking hormonal drugs;
• taking vitamins. in particular, group B. it is also possible to reduce the reaction when taking vitamin C and D.

An increase in sensitivity can be observed in some diseases, namely:

• thyroid disease. in particular Graves' disease;
• pneumonia;
• bronchial asthma;
• acute rheumatic fever;
• the presence of chronic foci of infection;
• flu.

It should also be said about the turn of the Mantoux test.

This concept is called the early period of tuberculosis infection, in which a hyperergic reaction is possible, but there are no local signs of the process.

The turn is set in the following cases:

1. When a negative sample becomes positive;
2. An increase in the diameter of the sample in comparison with the previous one by 6 mm or more.

In any case, the turn of the test does not mean that the child has tuberculosis. This may indicate that mycobacterium tuberculosis has entered the body, but not the development of the disease itself.

Mycobacterium tuberculosis under a microscope

Normally, the Mantoux test is performed from 12 months and is done every year until the child reaches 14 years of age. However, there are risk factors due to which the test has to be done twice a year starting from 6 months. These factors include:

• for any reason, the child was not vaccinated with BCG in the maternity hospital;
• HIV infection;
• diabetes;
• Chronical bronchitis;
• long-term treatment with hormonal drugs.

In the event that a child who has not been vaccinated in the first year of life is given BCG-M, the Mantoux test schedule changes to normal.

Mantoux Care

It is extremely important to understand what rules must be followed after the test. Yes, it is prohibited:

• scratching the injection site;
• lubricate the papule with any drugs or creams;
• apply a bandage or patch to the injection site.

Some parents mistakenly believe that after the Mantoux test, you should not wash or wet the injection site. However, this is fundamentally wrong.

The reason for such an erroneous judgment is that earlier tests were used that were administered not intradermally, but cutaneously, and getting water into the injection site could distort the result.

Now this method of administration is not used, so after the test, you can safely take a bath.

How to measure Mantoux in a child

The first thing you need to know is that the sample is evaluated three days later, after the introduction of tuberculin. First, there is an external evaluation. The reaction can manifest itself in two ways:

1. Redness;
2. Infiltration. This species is characterized by the formation of a dense protruding area at the injection site - papules.

Then the size of the papule is measured with a transparent ruler in the transverse direction. It is important to remember that it is not redness that is evaluated, but the size of the infiltrate.

So, the following types of reactions are distinguished:

1. Negative. Completely no changes on the skin;
2. Doubtful. The papule is absent or does not exceed 4 mm;
3. Mild. The size of the papule varies from 5 to 9 mm;
4. Medium. The size of the papule is 10-14 mm;
5. Expressed. The size of the papule is greater than 14 but less than 17 mm;
6. Hyperergic. The papule diameter exceeds 17 mm.

In any case, the Mantoux test occurs in all children individually and depends on several factors.

Norma Mantoux in children by years

Depending on age, the normal size of papules may vary.

In the first year, the large size of the papule is explained by the recent vaccination. Also, the results of the examination may depend on the immunity passed from mother to child.

Side effects of the Mantoux reaction and allergy symptoms

The most common side effects of the procedure are all kinds of allergic reactions. So, quite often, in the form of side effects, they reveal:

• increase in body temperature;
• the appearance of a rash;
• loss of appetite;
• lethargy;
• nausea and vomiting;
• attacks of bronchial asthma.

However, side effects are usually associated with the mistakes of doctors who did the Mantoux test in the presence of contraindications.

What does Dr. Komarovsky say about the Mantoux test in children

According to Dr. Komarovsky, supporters of the ban on Mantoux often say that the mixture contains phenol.

However, it is contained in such a low dosage that for a negative effect on the body, more than 1000 samples must be injected. It should also be noted that phenol is formed in the body and is normal, and is also found in many foods that are often eaten.

1. The Mantoux test must be performed before vaccination;
2. If this was not possible, then the test is allowed only one month after vaccination;
3. It is not recommended to conduct a Mantoux test after using blood products. You need to wait 2 weeks;
4. It is recommended that the annual sampling be carried out in the same season. Best in autumn time;
5. When introducing samples, it is necessary to alternate hands. For example, in even years to the left, in odd years to the right.

Thus, according to Dr. Komarovsky, Mantoux is a fairly safe test, which is extremely important in the diagnosis of such a serious disease as tuberculosis.

Refusal of the Mantoux test, search for an alternative

Sometimes, parents are extremely negative about this test, or the child has a strong allergic reaction to Mantoux. In such cases, the study is not possible. However, it is important to control the development of such a serious pathology as tuberculosis.

To this end, modern medicine offers the following research methods:

1. Immunogram. This study allows you to assess the state of the body's immune system. However, it does not accurately determine whether an infection has occurred or not;
2. Suslov's method. Concludes in the study of a drop of blood to which tuberculin is added. This technique is also characterized by low diagnostic significance and is considered reliable only in half of the cases;
3. Serological study. Aimed at the detection of IgG specific for the antigen of mycobacteria;

In any case, the Mantoux test remains the most accessible and accurate method for testing for tuberculosis.
