We report the case of a 7-month-old child with failure to thrive. Celiac disease was suspected because of highly raised antigliadin IgA and IgG antibodies and subtotal villous atrophy. In peripheral blood mononuclear-cells cellular proliferation was found in response to birch pollen, rye pollen and hazelnut extract. Born in June 1992 the infant had not yet experienced a birch pollen season. He had been fed with birch pollen allergy-associated carrot, apple and potato beginning at 6 weeks of life. In the serum, specific IgG, IgM and IgA to birch pollen and profilin, rye pollen and hazelnut antigens were detectable, indicating possible in utero sensitization or T cell cross-reactivity due to early sensitization with related food antigens.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D000485	Allergens	Antigen-type substances that produce immediate hypersensitivity (HYPERSENSITIVITY, IMMEDIATE).	Allergen
D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
