A variety of anti-infective drugs and blood products were used in the treatment, and all achieved lasting remission.Conclusions:Children with high-risk ALL after severe infection can acquire lasting remission, which may be related with the production of infection stimulating inflammatory factors and cytokines to activate certain immune pathways, or various kinds of antibiotics, blood products participating in the immune regulation to make the body regain the immune surveillance function of the tumor cells.
