The total IgE concentration was 165 kU/l, and rice specific IgE (CAP-FEIA, Pharmacia, Uppsala, Sweden) was 13.2 kU/l (Class 3) (Orhan and Sekerel, 2003 ).
A CAP class 4 was obtained to both rice and peanut at age 6 in the patient of Fiocchi et al. (2003) . At age 8, specific IgE to rice was 18.50 UI/mL.
The total IgE concentration was 55 kU/l, and IgE specific to rice (CAP-FEIA, Pharmacia, Uppsala, Sweden) was 4.6 kU/l (Class 3) (Wütherich et al. 2002 ).
Romano et al. (2001)  found that 24/54 patients were CAP positive to rice (32 were either CAP or SPT positive).
Caffarelli et al. (1997)  found a single patient had a positive CAP for rice and peanut.
Guinnepain et al. (1996)  reported a specific IgE of 16.4 kU/l for rice in a single patient.
Urisu et al. (1991)  found that sera from 31 patients which showed positive RAST values for rice grain extract were also RAST positive for RP16KD. In 17 subjects leukocyte histamine releases was also triggered by RP16KD.
Musken et al. (1991)  reported a positive RAST with raw rice but negative with cooked rice in a single patient..
Limas et al. (1990)  reported the 4 sera gave positive RAST (class 2-4).
Matsuda et al. (1988)  reported IgE binding to a purified 16 kDa protein, RAP, by ELISA using each serum at 4 dilutions (1/100 to 1/800).
Shibasaki et al. (1979)  investigated the lymphocyte-stimulating properties of rice glutelin and globulin fractions. All fractions were found to be reactive with specific IgE antibody, and two of three fractions from gel filtration revealed lymphocyte-stimulating activity. RAST inhibition revealed considerable cross-reactivity of IgE antibody with the glutelin and globulin fractions.
