Objective: To examine and compare the characteristics of food protein-induced enterocolitis syndrome (FPIES) caused by rice and cows milk/soy.
Design: Retrospective study of children presenting with FPIES to the Childrens Hospital at Westmead, NSW, Australia, over a 16-year period.
Results: There were 14 children with 26 episodes of rice FPIES compared with 17 children with 30 episodes of cows milk (n = 10) or soy (n = 7) FPIES. Children with rice FPIES were more likely to have FPIES caused by other foods (36%) than children with FPIES caused by cows milk/soy (0%). Rice caused more episodes of FPIES before a correct diagnosis was made (median 4 (range 1–4) vs median 2 (range 1–4)) and triggered more severe reactions with higher rates of intravenous fluid resuscitation (42% vs 17%) than reactions caused by cows milk/soy.
Conclusions: This study highlights the emerging importance of rice, a food commonly thought to be "hypoallergenic", as a significant trigger of FPIES. Paediatricians should be aware that rice not only has the potential to cause FPIES, but that such reactions tend be more severe than those caused by cows milk/soy.
