Successful desensitization with anakinra in a case with immediate hypersensitivity reaction

1. Physicians and allergy specialists caring for patients undergoing bariatric surgery should be aware of the delayed anaphylactic reactions from drugs, specifically the antibiotics. 2. The mechanism of anaphylaxis in these patients may or may not be different, but the absorption of drugs seems to be the issue and requires more studies. 3. We encourage physicians to report anaphylactic and other allergic reactions in patients undergoing bariatric operations to have further idea about these reactions.
