Objective: Repeated respiratory infection (RRI) is one kind of pediatric commonly encountered disease. We analysed variety of the function of the pituitary-adrenal axis of the sick children whom had been treated with glucocorticoid hormone, researched rational administration in order to control RRI and improve the health status of children.

Methods: 71 cases of RRI, and 35 cases of them are under 5 years of age, 36 of them between 5-12. In 28cases, routine dose of Prednisone (p.o) or Hydrocortisone (iv.dr) were used, it is the hormone treatment group. The radio-immunity technique was applied. All the subjects were sampled at 8-9 o’clock a.m, after refrigerated contrifugation, 200ul of serum was conserved in refrigerator.

Results: In seven of the RRI group, it was found that the concentration of serum cortisol had increased. The difference of serum concentration of cortisol, ACTH between RRL group and control group is insignificant. The result is identical between the age groups. Comparing with the control group, the difference of concentrations in insignificant (P<0.05). The frequence of episode, course of disease and seriousness of illness are insignificant.

Conclusion: The reaction of this axis is favorable in stress state. The secretion of glucocorticoid hormone increases temporarily. It can’t change the axis to administer with glucocorticoid, and the administration can’t improve the curative effect. So glucocorti-Coid shouldn’t be used generally to RRI.
