Women with inherited thrombophilia and recurrent miscarriage might benefit from preconceptional antiagreggation with low-dose acetylsalicylic acid (ASA), but concerns about severe adverse reactions may prevent physicians from performing this treatment in patients with ASA hypersensitivity. We report the first known case of ASA desensitization in a 41-year-old woman with inherited thrombophilia, who had homozygosity (4G/4G polymorphism) of the plasminogen activator inhibitor-1 (PAI-1) gene and first trimester recurrent miscarriage, and had previously presented with anaphylaxis to ASA. Desensitization was completed despite one self-limited adverse reaction, and the patient has maintained a daily ASA intake of 100 mg with good tolerance.
