Phenotypic parameters predict time to normalization in infants with hypogammaglobulinemia.

Purpose: Infants with recurrent infection may be found to have hypogammaglobulinemia without impaired specific antibody responses. Many will be diagnosed with transient hypogammaglobulinemia of infancy.

Methods: This study used a parametric survival analysis of 100 infants with hypogammaglobulinemia to predict time to normalization.
