Pathophysiological Study of Characteristics of the Changes in the Cutaneous Immune System After Intradermal Antigen Injections (LBP003)
LBP003: Characteristics of the Changes in the Cutaneous Immune System After Intradermal Antigen Injections
연구 개요
상세 설명
Realisation of 2 groups of healthy subjects with 2 intradermal injection of 50 µl of tuberculin + 2 intradermal injection of 50 µl of physiological serum. 5 biopsy performed on 2 Tuberculin injection site, 2 physiological serum site and 1 on healthy skin site :
- Group A : healthy young subjects(18 to 40 years old) : 18 subjects
- Sub-group A1 (biopsy 30 minutes after injection) : 6 subjects
- Sub-group A2 (biopsy 4 hours after injection) : 6 subjects
- Sub-group A3 (biopsy 72 hours after injection) : 6 subjects
- Group B : healthy old subjects(60 to 75 years old) : 18 subjects
- Sub-group B1 (biopsy 30 minutes after injection) : 6 subjects
- Sub-group B2 (biopsy 4 hours after injection) : 6 subjects
- Sub-group B3 (biopsy 72 hours after injection) : 6 subjects
Determination of the best time (30 minutes, 4 hours or 72 hours)for intradermal vaccination caracteristics after group A and B data analysis. From these results, last group of immunosuppressed patients performed:Group C with 6 immunosuppressed patients (18 to 60 years old)
