title: Immunotherapy with alginate-conjugated two grass pollen extract in patients with allergic rhinoconjunctivitis.
abstract: The aim of the present study was to evaluate the clinical and immunological effects of specific immunotherapy with alginate-conjugated two grass pollen extract in patients with rhinoconjunctivitis. A total of 52 patients were admitted to the study. Before and after 3 years of immunotherapy quantitative skin test (QST) to Dactylis glomerata (Dg) and to Phleum pratense (Php), variation of grass specific IgE and IgG4 and nasal challenge with the aqueous extract of the two grasses were compared. Each patient kept a daily record of symptoms and medication required during pollen season. In all patients a significant decrease in QST and a significant increase in grass specific IgG4 was observed. In 47 patients a significant decrease in nasal symptom scores and drug consumption was observed. In 5 patients no significant decrease in nasal symptom scores was observed.
