[Reasons for recurrent respiratory tract inflammations in children].

Respiratory tract inflammations are among the most frequent diseases in children. In natural conditions, respiratory tract is constantly prone to environmental pathogens. In fighting the respiratory tract infections both non-specific and specific: humoral and cellular immune mechanisms, related to mucosa-associated lymphoid tissue (MALT), take part.

Humoral and cellular immunity in children with Mycoplasma pneumoniae infection: a 1-year prospective study.

To determine whether children have persistent abnormalities in cellular and humoral immunity development after acute Mycoplasma pneumoniae infection, serum immunoglobulin G (IgG), IgA, IgM, and IgE levels and lymphocyte phenotypes were determined. There were no changes in the levels of IgG, IgM, IgA, or CD4+ or CD19+ lymphocytes that were measured in M. pneumoniae-positive patients after 3 months or after 12 months, but there were increases in these in M.
