We quantitated the amount of circulating IgG capable of binding to normal donor platelets in vitro using an 125I-monoclonal anti-human IgG assay, as well as the amount of IgG associated with the patients' platelets before and following therapy. We found no evidence for a decrease in platelet-specific IgG antibodies in these patients undergoing an acute response to therapy. These data suggest that the short-term efficacy of intravenous gammaglobulin is due to effects other than a substantive reduction in platelet reactive antibodies, such as the alteration of IgG-coated platelet destruction.}, issn = {0006-4971}, doi = {10.1182/blood.V73.3.662.662}, url = {https://doi.org/10.1182/blood.V73.3.662.662}, eprint = {https://ashpublications.org/blood/article-pdf/73/3/662/599313/662.pdf}, }
