Abstract
The clinical usefulness of a hypoallergenic rice (HRS-1) which was produced by enzymatic decomposition of the constituent proteins of original rice was evaluated in a multicentre study in 44 subjects with recalcitrant atopic dermatitis (AD), who were suspected of having rice allergy. The subjects were fed for at least 4 weeks with HRS-1 instead of eliminating both regular rice and wheat from their daily diet. The extent of overall skin lesions was expressed by using the AD affected area and severity index (ADASI). A statistically significant decrease in ADASI was observed at the 2nd and the 4th week readings and at the end of the study. A provocation test with regular rice was carried out in 5 of 44 subjects following the HRS-1 therapy. An obvious increase in ADASI was found in all of these 5 cases just after this procedure. On final evaluation, 77% of the patients tested showed 'moderate' to 'remarkable' improvement, and 59% of the patients a 'moderate' to 'remarkable' reduction in use of the steroid ointment concomitantly used for the treatment. Finally, HRS-1 was evaluated as 'useful' or 'very useful' in 69% of the subjects.
