Objective: To study on the changes of red cell immunity in children with acute infectious diseases including acute upper respiratory infections (AURI), acute bronchopneumonia and acute infectious diarrhea and control group (40 cases normal children.

Methods: The indexes of red cell immune function including: the rosette formation of RBC-C3b receptor (RBC-C3bRR), the rosette formation RBC immunocomplex (RBC-ICR), the rosette formation of the RBC enhancing factors (REF) and the rosette formation RBC inhibitory factors (RIF), which were detected by Ys yeast methods.

Results: the RBC-C3bRR, RBC-ICR, REF and RIF in control group were as following respectively: RBC-C3bRR 13.140±1.606, RBC-ICR 6.785±1.452, REF 64.637±13.804 and RIF 20.283±8.251; 54 cases children with AURI were: 11.237±3.744, 4.909±2.879, 44.909±12.405 and 22.920±4.928; 74 cases children with acute bronchopneumonia were: 8.016±2.725, 5.531±1.397, 51.809±13.689 and 22.203±5.733; 66 cases children with acute infectious diarrhea were: 8.641±2.137, 6.706±1.800, 48.700±13.410 and 24.944±6.155; the RBC-C3bRR, RBC-ICR, REF in children with AURI and acute bronchopneumonia were lower than that of  control group (p<0.05), and EIF was the same as normal(p>0.05); the RBC-C3bRR, REF and RIF  in children with acute infectious diarrhea were lower than that of control group (p<0.05), and the RBC-ICR was higher than that of control group (p<0.05).

Conclusion: The results show that the red cell immune function in children with acute infectious diseases is decreased and the changes of  red cell immunity in children with acute infectious diseases are probably relation to the kinds of pathogenic organisms and infectious parts.
