A safe protocol for rapid desensitization in patients with cystic fibrosis and antibiotic hypersensitivity.

Background: CF patients often demonstrate hypersensitivity to one or multiple antibiotics due to frequent and repeated exposures. Attempts at antibiotic desensitization in this population are historically complicated by higher reaction rates, failure to complete the procedure and consequent withholding of first-line therapy. This study evaluates the outcomes of a rapid desensitization protocol developed at our institution.

Hypersensitivity reactions to chemotherapy: outcomes and safety of rapid desensitization in 413 cases.

Background: Hypersensitivity reactions (HSRs) to chemotherapeutic drugs, including mAbs, often require that the provoking medication be discontinued, thus raising a dilemma for the caregiver: further use could precipitate a severe, even fatal, allergic reaction on re-exposure, but alternative drugs might be poorly tolerated or much less effective compared with the preferred agent.

Objective: We have developed a standardized rapid desensitization protocol for achieving temporary tolerization to drug allergens. In this study we evaluate the safety and efficacy of this protocol.

Perioperative anaphylaxis in a 44-year-old man.

This article presents a case report of perioperative anaphylaxis in a previously nonallergic 44-year-old man undergoing cervical spine surgery. After receiving general anesthesia with midazolam, propofol, lidocaine, fentanyl, rocuronium, and sevoflurane and cefazolin for prophylaxis, the patient developed hypotension, tachycardia, bronchospasm, and generalized erythema. A serum tryptase concentration was markedly elevated 2 hours after the anaphylactic episode.
