Objective: To analyze the cause of the anaphylactic reaction after a standard artificial insemination process in a patient diagnosed with asthma.
Design: Case report.
Setting: Residencia Sanitaria Virgen de la Arrixaca (Murcia, Spain) and University of the Basque Country (Vitoria, Spain).
Patient(s): A 30-year-old woman with a previous medical history compatible with respiratory allergy who suffered an anaphylactic reaction after an artificial insemination with spermatozoids in capable medium (Upgraded B2 INRA medium; Laboratories CCD, Paris, France).
Intervention(s): Cutaneous tests and specific IgE levels to inhalant allergens, grass and Olea pollens, and insemination medium were performed.
Main outcome measure(s): Specific IgE levels to mammal epithelia and bovine serum albumin (BSA).
Result(s): Skin prick tests were positive for inhalant allergens such as mites, cat, dog, horse, and rabbit epithelia, grasses and Olea pollens, and the insemination medium. The beta-lactamic tests were negative. The determination of specific IgE demonstrated positive values to mammal epithelia and mammal serum albumins including BSA.
Conclusion(s): We report a case of an anaphylactic reaction to the BSA included in the insemination culture medium induced by a subclinical sensitivity to serum albumins of mammal epithelia. A previous testing with the medium is recommended and specific testing might be needed in women who have a history of animal epithelium allergies.
