Immunogenicity, Immunological Memory and Monitoring of Disease Activity Following an Anamnestic Immunization With the 13-Valent Pneumococcal Conjugate Vaccine in Children With Idiopathic Nephrotic Syndrome.

ABSTRACT

Anamnestic 13-valent pneumococcal conjugate vaccine immunization did not affect the relapse risk in pediatric idiopathic nephrotic syndrome. Pneumococcal serotype (PS)-specific antibody titers increased significantly in all groups. Children receiving immunomodulatory treatments (IMTs) displayed significantly lower levels of PS-specific antibodies for 3/8 serotypes tested. PS-specific B-cell counts significantly increased only in healthy controls and patients receiving corticosteroids.
