Table 3 Peanut-Allergic Siblings of Index Children

From: Should Younger Siblings of Peanut-Allergic Children Be Assessed by an Allergist before Being Fed Peanut?

Siblings of Index Child Sibling from Table 2 Confirmed Diagnosis with Allergist* Evidence of IgE SPT or capRast
Cases    
1 6 Yes capRast > 100 kUa/L
2 7 Yes capRast > 100 kUa/L
3 9 Yes capRast > 100 kUa/L
4 17 Yes SPT mean wheal diameter 21 mm
Controls    
1 NA Yes SPT mean wheal diameter 21 mm
2 NA Yes capRast > 100 kUa/L
3 NA Yes Large SPT+ (no measurement recorded)
4 NA Yes SPT mean wheal diameter 8 mm
5 NA Yes capRast = 90.3 kUa/L
6 NA Yes capRast = 22.8 kUa/L
7 NA Yes SPT mean wheal diameter 14 mm
8 NA Yes SPT: 4+ reaction (pseudopods)
9 NA No Not confirmed
10 NA Yes capRast > 100 kUa/L
11 NA Yes capRast = 2.3 kUa/L; no oral challenge
  1. capRAST = FEIA for peanut-specific IgE; NA = not available; SPT = skin-prick test.
  2. *Allergist diagnosis included a definitive history of an adverse reaction to ingestion of peanut and evidence (in vivo or in vitro) of IgE toward peanut. Only control 9 was not confirmed.
