Adverse Occurrence type:
MPHO Type:
Estimated frequency:
Rare
Time to detection:
3 months
Alerting signals, symptoms, evidence of occurrence:
Relative lack of specific IgG2 anticarbohydrate antibodies in the donor and the recipient after transplant. IgG2 deficiency is considered as a prognostic marker for permanent lack of IgA.
Demonstration of imputability or root cause:
Bone marrow transplant from HLA matched sibling with selective IgA deficiency, results in IgA deficiency in the recipient. This recipient had normal IgA levels prior to transplant. Both the recipient and donor demonstrated the presence of IgA genes and it was speculated that the IgA deficiency is manifested at stem cell level.
Imputability grade:

Expert comments for publication:
One of the few published case of transfer of selective IgA deficiency by marrow transplantation.There are other case reports that demonstrate correction of IgA deficiency in a marrow transplant recipient after transplantation from a donor who had no IgA deficiency
