Increase in de novo allergies after paediatric liver transplantation: The Brisbane experience

Abstract

Pediatric liver transplantation is a successful procedure with 10-yr survival rate of 70%; following transplantation, the emphasis on promoting good quality of life is important. The increasing prevalence of allergic disorders in the general population and an increase in food allergy following solid organ transplantation are described in patients, especially in children, but the contribution to morbidity post-OLT has not been addressed. Identifying the incidence de novo allergies post-OLT performed by QLTS over 11 yr. Comprehensive medical record review of OLT recipients during study period. From 1st July 1998 to 1st August 2009, 78 children received 85 cadaveric OLT; 60 children survived. Allergic disease was documented in 24/60 (40%) survivors. De novo food allergies were diagnosed in 12/60 (20%) (Table 2), 9/12 occurred in children who were infants at time of transplant. Ten of 12 had severe allergies, six anaphylactic; 6/60 (10%) carry an EpiPen. Only 31/60 (51%) diagnosed are followed in Queensland, suggesting severe allergic disease in our cohort is an underestimate. Serious allergic disease post-OLT is clinically important, especially in infants at time of transplant, and should be targeted for specialist allergist referral and risk management. [Table: see text].
