Allergies and Appendicitis: A Surprising Link

Kids with allergies have a lower risk for complicated appendicitis, which sometimes requires multiple surgeries and longer hospital stays, according to a study from Lund University and Skåne University Hospital in Sweden. Results of this 10-year study were published in JAMA Pediatrics.

The Swedish study involved 605 children under 15 who had surgery for appendicitis between 2007 and 2017. The researchers compared outcomes for children with common allergies to pollen and animal fur (102 children) to those without allergies (503 children) and found that those with allergies were three times less likely (19.6 percent vs. 46.9 percent) to have complicated appendicitis.

Worldwide, appendicitis is the most common reason for emergency abdominal surgery (called appendectomy) and often occurs in young people. About one-third of children with appendicitis develop a complicated form, for reasons that aren’t fully understood. Results of this study suggest there may be an immunological component to complicated appendicitis and may lead to new diagnostic tools, such as blood tests.
