The three main allergens are storage proteins: Ana o 1, Ana o 2 (cupin superfamily) and Ana o 3 (prolamin superfamily).&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; Lifetime avoidance of cashew nut is currently recommended for those with CNA. However, little is known about the natural history of CNA.&lt;/p&gt;&lt;p&gt;We report a cohort of five children with severe anaphylaxis to cashew nut who recovered and were able to eat cashew nut after a successful oral food challenge (Table 1). They all presented severe anaphylaxis according to the ordinal food allergy severity score (oFAAS-5)&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; (grade 3 to grade 5) at diagnosis at a mean age of 3 years [1.5–4]. Two patients had no atopy, one had a personal and familial atopic history and two others had only personal atopy. They all had no allergies or sensitizations to peanuts or tree nuts. Three patients consumed native cashew (between one and three cashew units) during the first reaction and two patients consumed cashew in cooked meals (unknown quantity). Allergology explorations were performed a mean 1.1 years [0.15–5] after the first reaction. All patients were sensitized to pistachio, but only two had a confirmed food allergy to pistachio. Skin prick tests (SPTs) were performed with commercial extract (ALK-Abello) and were deemed positive when wheal size was ≥ 3 mm. Cashew SPTs were positive for four children (mean 6 mm, range [3–20]). Cashew-specific IgEs (ImmunoCap® by Phadia 1000 System, Thermo Fisher Scientific) were positive for all patients, with a mean of 1 KU/L [0.36–2.49]. The recombinant Ana o 3 was not tested for at diagnosis for three patients and was positive for two of them (0.63 and 1.97 KU/L). After the reaction, they all observed strict avoidance of cashew and pistachio in their diet, without any recurrence. During a mean follow-up of 2.4 years (range [1–4]), the SPT and the cashew-specific IgEs became negative (Figure 1) and all patients tested negative for recombinant Ana o 3. An oral food challenge in four patients was successful at a cashew nut cumulated dose of 7800 mg. One patient refused the challenge, but after a successful pistachio challenge, he ate one cashew unit at home without any reaction.&lt;/p&gt;&lt;p&gt;We reported the cases of five children who presented severe anaphylaxis to cashew nut and who spontaneously recovered after a mean follow-up of 2.4 years [1–4]. As for peanut, ingestion of cashew is associated with a high rate of severe anaphylactic reactions,&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; but in our cohort it seemed not to be correlated with persistence of the allergy.

The LPT test is based on a single blood sample and has mostly been used to detect drug hypersensitivity.
