[Immunobiomarkers in healthy children from two Polish cities]

Determination of lymphocyte subpopulation values and immunoglobulin concentrations is an important tool in the assessment of immunologic system. The only way to establish their reference values in pediatrics is to perform research on large populations of healthy children from different age ranges in various areas of the world. Such research was conducted within the framework of the Central European Study of Air pollution and Respiratory Health (CESAR). It involved examination of children 9-11 years old from six countries in Central-Eastern Europe. We present the results of the Polish section of CESAR and compare them to the data provided by different authors from all over the world. Our data are relatively numerous: we examined 80 children recruited from primary schools in two Polish cities, Swietochlowice and Pszczyna. The values are similar to those obtained by other researchers. There is a need to establish an extensive and uniform data base of immunobiomarkers for healthy children in different age groups.
