Threshold dose distribution and eliciting dose of cashew nut allergy

A previous study1 found that 137 of 179 cashew nut sensitized children (76.5%) suspected of having cashew nut allergy had a positive double-blind, placebo-controlled food challenge (DBPCFC result), with 63 of 137 children (46%) manifesting subjective and/or objective symptoms to the lowest dose (1 mg of cashew nut protein). The primary aim of this study was to determine the distribution of threshold doses and the eliciting doses (EDs) in this population. The secondary aim was to investigate whether children who reacted to 1 mg of cashew nut (n = 63) could react to even lower doses than 1 mg (low-dose follow-up study).
