RODRIGUEZ-GONZALEZ, Moisés  e  CASTELLANO-MARTINEZ, Ana. Coronary vasospasm in a child allergic to latex: Kounis syndrome. Arch. argent. pediatr. [online]. 2019, vol.117, n.5, pp.e514-e518. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2019.e514.

Kounis syndrome consists of the simultaneous occurrence of anaphylaxis and acute coronary syndrome. It is a rare entity that may be underdiagnosed in paediatrics. The clinical presentation is variable, atypical and usually unexpected, and it carries possible serious complications such as ventricular arrhythmias, myocardial infarction and sudden death. Therefore, an early diagnosis and treatment for myocardial revascularization and the anaphylactic reaction are crucial. We report the case of an 11-year-old male who, after contact with latex, presented an anaphylactic reaction associated with coronary vasospasm, with rapid and complete recovery after administration of intramuscular adrenaline. The cardiological study ruled out coronary pathology as the cause of the event. The allergy study revealed a latex-fruit (kiwi and pineapple) cross-reactivity syndrome. The patient was diagnosed with type I Kounis syndrome triggered by latex, recommending the avoidance of possible triggers.
