Abstract:
Oral mite anaphylaxis (OMA) caused by mite-containing food that was initially reported in 1993 has become commonly known after accumulating the case reports. Although it has been pointed out as being related to aspirin intolerance overseas, there are only a few cases reported in Japan so far, particularly no case for children. We report a child case which is seemingly related to OMA and aspirin intolerance. The case is for a boy at the age of 10. After eating Takoyaki with the ingredient of mite-containing flour, he was diagnosed as OMA due to the occurrence of anaphylaxis with respiratory discomfort, abdominal pain, and vomiting. One month later, he was suspected of aspirin intolerance, since he presented with symptoms such as swelling of the eyelid and coughing after taking loxoprofen which he never have taken, and intradermal test with loxoprofen was negative. Because the mechanism with a connection between mite allergy and aspirin intolerance still remains unknown, it would be necessary to accumulate more cases and clarify the pathology in future.
Insights
Oral mite anaphylaxis (OMA) is a rare food allergy. This case report details a 10-year-old boy experiencing OMA and potential aspirin intolerance, highlighting a possible link in children.
Area of Science:
- Allergy and Immunology
- Pediatric Medicine
- Gastroenterology
Background:
- Oral mite anaphylaxis (OMA), triggered by consuming mite-contaminated food, was first reported in 1993.
- While OMA is recognized globally, cases, especially in children, are infrequent in Japan.
- A potential association between mite allergy and aspirin intolerance has been noted internationally.
Observation:
- A 10-year-old boy experienced anaphylaxis, including respiratory distress, abdominal pain, and vomiting, after eating Takoyaki containing mite-contaminated flour, leading to an OMA diagnosis.
- He later exhibited eyelid swelling and coughing after ingesting loxoprofen, a non-steroidal anti-inflammatory drug, suggesting possible aspirin intolerance.
- An intradermal test for loxoprofen yielded negative results.
Findings:
- This case presents a potential link between oral mite anaphylaxis and aspirin intolerance in a pediatric patient.
- The co-occurrence of OMA and suspected aspirin intolerance in this child warrants further investigation.
- The underlying mechanisms connecting mite allergy and aspirin intolerance remain unclear.
Implications:
- This report underscores the importance of considering aspirin intolerance in children diagnosed with OMA, particularly when they exhibit adverse reactions to NSAIDs.
- Further research and case accumulation are crucial to elucidate the pathological relationship between mite allergy and aspirin intolerance.
- Understanding this connection may lead to improved diagnostic and management strategies for allergic conditions in children.
