title: Clinical and immunological studies of timothy antigen D immunotherapy.
abstract: The response to preseasonal immunotherapy with aqueous grass extract, timothy antigen D, or water-soluble timothy (WST) in alginate was compared in patients sensitive to grass pollen. Injections of antigen D in alginate produced little evidence of clinical or immunologic response. Treatment with aqueous grass extract or WST in alginate, on the other hand, significantly reduced the seasonal rise in grass-specific IgE. Aqueous extract therapy was also associated with a decline in leukocyte sensitivity during the pollen season, while WST treatment produced the greatest rise in hemagglutinating antibodies.
