Do citrus fruits worsen Crohn's symptoms?

"Immune sensitization to food, yeast and bacteria in Crohn’s disease" in Alimentary Pharmacology and Therapeutics (2001) [full article]
"The following groups of antigens were utilized: ...
3 Citrus mix (grapefruit, lemon, lime and sweet orange), 1/10 weight for volume. ...
The following positive proliferative responses were noted in Crohn’s disease patients: 13 to milk, 16 to cabbage, 14 to cereal, nine to citrus, 16 to peanut, 18 to E. coli, 11 to Bacteroides, 10 to Klebsiella, six to bakers yeast, and nine to brewers yeast."

"Gut mucosal response to food antigens in Crohn's disease" in Alimentary Pharmacology and Therapeutics (2002) [full article]
"Although the strongest data were obtained for a response to citrus fruit and yeast antigens, the individual data supported the possibility of an abnormal response to the full range of antigen groups tested. In an individual, any one or more of these protein groups may be important." [emphasis mine]
