Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To research and explore the antibody protection and immune memory after vaccination in children with KHE during sirolimus administration. To explore the feasibility (safety and efficacy) of vaccination in a timely manner during the administration of sirolimus in children with KHE. To search for back-up plans for vaccination regimens for KHE patients taking sirolimus in children who do not respond to primary vaccination.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Children with KHE have an early onset. KHE usually occurs in infants and young children less than 1 year old, of which neonates account for about 38.5%-60% of all cases. Due to the immunosuppressive effect of sirolimus, the vaccination was usually suspended after taking it, and children would be in a state of no immune protection. These children are at greatly increased risk of exposure to microorganisms and consequent infection. Therefore, it is necessary to vaccinate them against infectious diseases. However, vaccination with live vaccines has the potential to cause severe infections through reversion of the vaccine strain to a pathogenic form. Moreover, studies have also shown that protective antibodies are severely affected in transplant patients taking immunosuppressive drugs and in patients with solid tumors after chemotherapy. Loss of immune memory is very common, and marked deficits in B cell function and humoral immunity can persist even for years.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cases

Individuals diagnosed with KHE and treated with sirolimus. After immunoglobulin and flow cytometry assays, as well as outpatient evaluation and assessment, those participants will be vaccinated with live attenuated vaccines or inactivated vaccines in a timely order according to the advice. (Sirolimus Rapamycin 0.8mg/m2 bid po)

Intervention Type OTHER

No intervention

Controls

Healthy children with no immunodeficiency disease, vaccinated according to the National Immunization Program. Particpants should be age-matched with the case group.
