Best treatments for anaphylaxis

Understanding anaphylaxis

"Anaphylaxis" is the medical-index heading for a sudden, whole-body allergic reaction. The NLM's MeSH record defines it as "an acute hypersensitivity reaction due to exposure to a previously encountered ANTIGEN" whose course "may include rapidly progressing URTICARIA, respiratory distress, vascular collapse, systemic SHOCK, and death," and files the terms anaphylactoid reaction and anaphylactic shock under the same heading. According to MedlinePlus (NLM), the most common causes are reactions to foods (especially peanuts), medications, and stinging insects; it adds that other causes include exercise and exposure to latex. The 2023 AAAAI/ACAAI practice parameter puts lifetime prevalence at 1.6% to 5.1%. The point people get wrong is the recognition threshold: StatPearls (NCBI Bookshelf) states that "consideration for anaphylaxis is appropriate in the presence of 2 or more involved systems, even in the absence of airway involvement or hypotension" — so no collapse and no wheeze does not rule it out. StatPearls also reports that reactions "can also occur biphasically in up to 20% of cases," with symptoms recurring and peaking 8 to 11 hours after the initial reaction; that is why it recommends emergency department observation for 4 hours before discharge. On confirming it afterwards, the 2023 parameter says the diagnosis "can be supported by an elevated acute serum tryptase level," while cautioning that many cases of anaphylaxis are not associated with a tryptase elevation above the usual laboratory cutoff — a normal result does not undo the diagnosis. One age-specific point from that parameter: in infants, it suggests clinicians be aware that anaphylaxis is unlikely to be the initial reaction to a food or medication on first exposure. This is general information, not medical advice.
