Nonimmediate allergic reactions induced by Mesna
نویسندگان
چکیده
Mesna (2-mercaptoethane sulfonate Na), a drug that alleviates cyclophosphamide (CYC)-induced hemorrhagic cystitis, is frequently used to treat cancer and collagen diseases. A 33-year-old woman presented with high fever during CYC-based induction therapy for systemic lupus erythematosus. Her final diagnosis was mesna-induced drug hypersensitivity. Although mesna is widely used, allergic reactions are rare. This may be because of misdiagnosis as a primary disease flare-up, infection, or CYC-induced hypersensitivity reaction, which are commonly reported. Thus, accurate diagnosis is important for completion of the CYC-based regimen.

متن کاملUpdate on the evaluation of hypersensitivity reactions to betalactams.
Hypersensitivity reactions to betalactams (BLs) are classified as immediate or nonimmediate. The former usually appear within 1 h of drug-intake and are mediated by specific IgE-antibodies. Nonimmediate reactions are those occurring more than 1 h after drug-intake, and they can be T-cell mediated. The diagnostic evaluation of allergic reactions to BLs has changed over the last 5 years, for seve...
