Although certain neurological conditions such as microcephaly are recognized as associated features of some IEIs, NDDs are less well described. We reviewed published clinical descriptions of IEIs and found a number of comorbid NDDs in these patients, including autism spectrum disorder (ASD), behavioral deficits, and intellectual disability. Given the lack of uniform assessments for NDDs, we suspect they may be underdiagnosed in IEIs.

Although most cases occur outside healthcare settings, data indicate a high emergency admission rate due to insect stings.

Targeting risk factors could be a clue to improve these statistics and the prognosis of the disease.Potential risk factors for severe HVA in the European population are basal serum tryptase (BST) above 8 μg, mast cell disorders, the absence of skin symptoms, and cardiovascular conditions requiring the use of beta blockers and ACE inhibitors.

HVA clinical patterns could be worsened by one Hymenoptera sting, a patient's history with mast cell disorders, or cardiovascular diseases.
