Background
The presence of pre-formed IgA anti–β2-glycoprotein I antibodies (IgA-aB2GP1ab) has been related to early graft loss after
kidney transplant. Because β2-glycoprotein I is produced in both the kidney and heart, we aimed to assess whether
the presence of these antibodies may also be associated with poor outcomes after heart
transplantation (HT).
Methods
A 2-year follow-up retrospective analysis of 151 consecutive patients who underwent
HT between 2004 and 2012 was performed to assess the role of this pre-formed antibody
type in HT. The population was divided into 2 groups according to the presence of
IgA: Group 1 was positive for IgA-aB2GP1ab (47 patients, 31.1%), and Group 2 was negative
for IgA-Ab2GP1ab (104 patients, 68.9%).
Results
Early mortality rates within the first 3 months were higher in Group 1 (27.7%) than
in Group 2 (9.6%). No differences in donor and recipient characteristics or in causes
of death were observed between groups. Multivariate analysis identified the presence
of IgA-aB2GP1ab, female gender and blood type A as independent risks factors for early
mortality after HT. A greater incidence of thrombotic events during the first 3 months
post-HT in Group 1 (23.4% vs 5.8%) and a greater presence of risk factors for thrombotic
events, which may have exacerbated them, were observed. After this period, no increase
in mortality or in thrombotic events was found when the 2 groups were compared.
Conclusion
Pre-transplant presence of IgA-aB2GP1ab is associated with both increased early mortality
rates and higher thrombotic events after HT.
