Аннотация
BACKGROUND: Hypersensitive reactions (HSRs) often require that the provoking medication be discontinued but chemotherapeutic drugs are often essential for the treatment of the disease. Rapid drug desensitization is a procedure that induces temporary tolerance to the drug allowing continuation of treatment in patients who have presented HSRs. Most of the desensitization protocols use 3 bags with sequential dilutions of the drug, which are infused in gradual steps. However, it has not been sufficiently investigated whether dilution is essential for successful desensitization.
OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of a new one-bag desensitization protocol which uses a single solution of 1 mg/mL throughout the procedure allowing to reduce time and simplifying the desensitization procedure.
METHODS: Retrospective observational study was carried out in adult patients with HSRs to chemotherapy agents who received a new nondilution one-bag desensitization protocol between 2016 and 2021.
RESULTS: A total of 130 desensitization procedures with an undiluted one-bag protocol were performed on 17 patients with HSRs to chemotherapy. One hundred and seven (82.3%) were for desensitization to CBDCA, 15 (11.5%) for oxaliplatin, 4 (3.1%) for paclitaxel and 4 (3.1%) for brentuximab. All of the 130 procedures were successfully accomplished, and all patients could receive their target dose. No breakthrough reactions (BTRs) occurred in 77% (100/130) of desensitizations, and only mild reactions (grade 1) with skin symptoms were observed in 23% (30/130) of desensitizations.
CONCLUSION AND RELEVANCE: The undiluted one-bag desensitization protocol was safe and effective and has been adopted as the standard of care at our institution in treating patients with HSRs to chemotherapeutic drugs as it requires less time and simplifies the desensitization procedure, optimizing risk management.
