研究概览
简要总结
Individuals with systemic lupus erythematosus (SLE, lupus) appear to be at increased risk for the development of shingles, a painful reactivation of the varicella zoster virus that causes chicken pox.
The investigators propose to study the immune response to commercially available Zostavax vaccine (shingles vaccine) in adult patients with SLE who have minimal disease activity and are on mild immunosuppressant medications, and to compare the immune response to that seen in healthy people following vaccination. Acceptable immunosuppressive drugs permitted in the study are those felt to be safe according to Centers for Disease Control guidelines.
Ten healthy people and 10 SLE patients (all over 50 years of age) will be recruited to receive a single, standard dose of Zostavax. Blood samples and physical examination will be performed prior to injection, then 2,6,and 12 weeks following vaccination. All participants will receive active vaccine, there is no placebo group.

研究组 & 干预措施
SLE patients
Subjects with mild SLE over age 50 years will receive open-label Zostavax vaccine.
干预措施: Zostavax vaccine (Drug)
Healthy subjects
Healthy subjects aged 50 years and older without any history of autoimmune disease will receive zostavax vaccine. Immune responses to varicella zoster virus and adverse events will be compared to those seen in SLE patients
干预措施: Zostavax vaccine (Drug)
结局指标
主要结局
Cell-mediated immune response to varicella at 12 weeks following vaccination
时间窗: 12 weeks
Peripheral blood will be drawn at baseline, then at 2,6, and 12 weeks following vaccination. Peripheral blood mononuclear cells will be assessed for measures of varicella-zoster specific immunity.
次要结局
- Antibody response to Zostavax vaccination(12 weeks)
- Adverse events(12 weeks)
