title: Immunodeficient states and associated rheumatic manifestations.
abstract: The molecular mechanisms of the primary immunodeficiencies have been further explored and provide insights into the regulation of the immune response and its role in autoimmune disease, infection, and malignancy. The critical role of CD40-CD40 ligand-mediated effects in T cell-dependent B cell activation, shown through the study of patients with common variable immunodeficiency and hyper IgM syndrome, suggests a potential narrow target for immunomodulatory therapy. A mouse model for chronic granulomatous disease has been developed and promises to be a source of future information. Optimal cost-effective therapy for primary immunodeficiencies continues to be defined, with the results of a large series of patients treated with subcutaneous immunoglobulin infusions reported. Further experience with polyethylene glycol adenosine deaminase and interleukin-2 conjugates is discussed.
