A new paper in Transplantation takes up an old question – can you passively transfer asthma or allergy? It seems so – the current study reports in 5 of 42 patients elevated IgE plus allergy symptoms. This is in line with earlier reports. Sorry to say — you can get allergy also by bone marrow transplantation.
Another paper in Blood on the same topic:
A total of 16 nonallergic recipients with allergic donors were reported to develop allergic disease posttransplant, however, conclusive information was available for only 5 cases. Allergic disease was reported to abate in 3 allergic recipients with nonallergic donors, however, conclusive information was available for only 2 cases. Problems in interpreting the reports include incomplete data on allergic disease in the donor or recipient pretransplant, not knowing the denominator, and the lack of controls. In summary, review of the literature generates the hypothesis that allergic disease is transferable
