Secondary antibody deficiency is associated with development of infection in kidney transplantation: Results of a multicenter study.

Background: We performed a multicenter study to assess the association between secondary antibody deficiency (immunoglobulin G [IgG] hypogammaglobulinemia combined with low levels of specific antibodies) and development of infection in kidney transplantation.

Methods: We prospectively analyzed 250 adult kidney recipients at four centers. The assessment points were before transplantation and 7 and 30 days after transplantation.

Monitoring of early humoral immunity to identify lung recipients at risk for development of serious infections: A multicenter prospective study.

Background: Infection is still a leading cause of death during the first year after lung transplantation. We performed a multicenter study among teaching hospitals to assess monitoring of early humoral immunity as a means of identifying lung recipients at risk of serious infections.

Methods: We prospectively analyzed 82 adult lung recipients at 5 centers in Spain.
