Thank you for your inquiry.
Anaphylaxis to growth hormone must be extremely rare. I am only aware of two cases in the literature, one that you cited and one other (1). Both of these are in the older literature. I could not find any other reference to anaphylaxis to growth hormone even in the package insert of recombinant DNA growth hormone.
Based on these two case reports, however, IgE-mediated reactions to growth hormone can occur, and can be treated successfully with a desensitization regimen.
Thank you again for your inquiry and we hope this response is helpful to you.
