[Behavior of serum concentrations of immunoglobulins G, M and A in the 1st week of illness in children with bacterial and viral diseases].

The serum concentrations of the immune globulins in children with acute infection of the upper respiratory tract, angina lacunaris, mumps and acute infection of the urinary tract within the first week of illness were analysed. In the adequate age group the values (altogether 540) of healthy and diseased children were confronted and statistically compared. Here the following characteristic changes were shown: the acute infection of the upper respiratory tract was characterized by an increase of IgG. In mumps a decrease of IgA was stated. As to the infections of the urinary tract in the younger age group an increase of IgM existed, in the older age group a decrease of IgA. The results refer to the dynamics of the immune globulins in the initial phase of the individual diseases.
