Continual observation of clinical and immunological parameters, in particular of salivary IgA, in tonsillectomised children.

In 106 tonsillectomised children the following parameters were measured before and after operation: clinical parameters (length, weight, postoperative complications), haematological parameters (BSR, Hg, PCV, RBC, and WBC), and immunological parameters (IgG, IgA, IgM, and salivary IgA); in a number of children measurements were taken over a period of more than 3 years. Standard values of salivary IgA in relation to total salivary protein were determined in noninfected children of various age groups. Compared to the standard and initial values, we found some statistically significant changes in the serum immunoglobulin levels and in the salivary IgA, but no irreversible pathological decrease in the above-mentioned parameters.
