What is the Mantoux test

The incidence of tuberculosis is sufficiently high throughout the world, including in our country. However, childhood tuberculosis in Russia are rare thanks to the timely detection and treatment of this disease. Detection of tuberculosis in children Tuberculosis in children - Actual problems of modern  Tuberculosis in children - Actual problems of modern
   due to the fact that, penetrating into the organism Mycobacterium tuberculosis cause sensitization (allergy) body. Allergies to identify Mycobacterium tuberculosis using Mantoux test, which is carried out by intradermal tuberculin - extract (lysate) from Mycobacterium tuberculosis, heat-killed.

Sensitization of the organism Mycobacterium tuberculosis is also being developed in response to vaccination against tuberculosis - BCG.

Reaction to Mantoux, a child may be different depending on the time that has elapsed since the BCG, and possible infection. On the third day after setting the Mantoux test at the injection site may occur a slight thickening of the skin - a papule. It is measured and evaluated. In order not to confuse the papule with reddening of the skin, it pressed against a transparent ruler - papule becomes white and has a clear edge. Measure the transverse dimension of the papules without taking into account its surrounding redness. Redness is recorded only if there is no papules.

Evaluation Mantoux test in children

When checking the Mantoux test is assessed on strictly defined criteria:

  • r.Mantu negative - a complete lack of infiltration (papule) at the injection site or a trace of infiltration injections with no more than 1 mm;
  • r.Mantu questionable - infiltrate the size of 2-4 mm, or only redness of any size without infiltration;
  • positive r.Mantu - infiltrate a diameter of 5 mm or more infiltration or growth with respect to the last year more than 5 mm (increasing r.Mantu); weakly positive r.Mantu - infiltration of 5-9 mm, medium intensity - 10-14 mm, expressed - 15-16 mm;
  • hyperergic (expressed excessively) r.Mantu - infiltration of 17 mm or more, or vesicles, necrotic (with the formation of vesicles and necrosis) reaction, regardless of the size of infiltration, lymphangitis and lymphadenitis Lymphadenitis - when inflamed lymph nodes  Lymphadenitis - when inflamed lymph nodes
   (inflammation of the adjacent lymphatic vessels and lymph nodes), child screenings (the emergence of several hotbeds around the main, parent).

Normal Mantoux children

What a r.Mantu considered normal in children? Normal reaction may be different, depending on the time elapsed from the date of vaccination against tuberculosis (BCG), which is conducted for all children in the hospital, as well as the size of the hem, the remainder of the vaccination:

  • 1 year of life, or one year after BCG - the norm is the quantity of infiltration after r.Mantu 5-15 mm (if after BCG scar was equal to 6-10 mm) or 5-11 mm (BCG scar from 2-5 mm);
  • 2 years of life - Mantoux test rate in children, if the size of the infiltrate remained unchanged or slightly decreased compared to last year; the value of BCG scar does not matter;
  • 3-5 years of life - the size of infiltration is reduced and does not exceed 5-8 mm;
  • 6-7 years of life - fading reaction to the doubtful or negative.

Bad Mantoux test a child

"Bad" r.Mantu - is a relative term. Since almost all TB-infected adult population, it is set to the time of the introduction of the organism Mycobacterium tuberculosis, ie tubinfitsirovanie. Moment tubinfitsirovaniya accompanied superelevation r.Mantu, that is, its growth compared to the previous figures. It says that under unfavorable conditions (fatigue, malnutrition, frequent stress and so on), a child may develop TB Tuberculosis - a full recovery is not guaranteed  Tuberculosis - a full recovery is not guaranteed
 .

A sign of turn shall be considered:

  • the appearance of the first positive r.Mantu (infiltration of 5 mm or more), though it was negative or doubtful;
  • previous amplification reaction by 5 mm or more;
  • hyperergic reaction (infiltration of more than 17 mm) irrespective of the limitations of vaccination;
  • r.Mantu kept at more than 12 mm after 3-4 years after BCG vaccination.

If you suspect an infection should first eliminate all factors that could affect the r.Mantu. It is an allergy to the components of tuberculin or to any other substances, which contacted the child, recently transferred disease, the introduction of a vaccine a month ago and so on.

The child, who was identified turn fully examined in order to eliminate the disease of tuberculosis, being treated with anti-TB drugs and watch for a year.

Mantoux test in children is very important. Due to its systematic, it is possible to prevent and promptly identify cases of childhood tuberculosis.
