Descriptive Information
Brief Title  ICMJE PNEUMOCELL - Conjugated Pneumococcal Vaccination in Patients With Immunoglobulin G-deficiency
Official Title  ICMJE PNEUMOCELL - Conjugated Pneumococcal Vaccination in Patients With Immunoglobulin G-deficiency
Brief Summary The aim is to study the immune response to conjugated pneumococcal vaccination (Prevenar13) in Immunoglobulin G-deficient patients and healthy controls. Our hypothesis is that the antibody response will be impaired in patients as compared with controls. In contrast, we postulate that the cellular immune response will be intact.
Detailed Description Ten patients with Immunoglobulin G1 and/or Immunoglobulin G2 deficiency will be enrolled together with 10 age and sex- matched controls. Blood-samples will be drawn at base-line and after 1, 2 and 4 weeks post-vaccination. Serum will be analyzed for opsonophagocytic antibodies. Peripheral blood monocytic cells (PBMCs) will be isolated, frozen and later analyzed for all time-points simultaneously. PBMCs will be stimulated with vaccine-antigens for 3-5 days and cellular activation markers will be measured together with cytokines (Interferon-gamma, Interleukin (IL)-5, IL-13, IL-10, IL-17, IL-22). In addition, levels of antimicrobial peptides in nasal fluid will be measured at baseline and after 4 weeks post-vaccination.
