This case was reported in a literature article and described the occurrence of anaphylaxis in a 44-year-old female subject who received Flu seasonal TIV Dresden. This case refers to patient 18 in the literature article. The subject's past medical history included anaphylaxis and allergic rhinitis. Concurrent medical conditions included asthma and drug allergy. On an unknown date, several minutes after receiving Flu seasonal TIV Dresden, the subject developed anaphylaxis. Serious criteria included GSK medically significant and life threatening. Additional event(s) included generalized pruritus, generalized rash, wheezing, shortness of breath, throat tightness, hoarse voice, cough, vomiting and diarrhea. The subject was treated with antihistamine, steroid (unspecified), oxygen and bronchodilator. The outcome of anaphylaxis was recovered/resolved. The outcome(s) of the additional event(s) included generalized pruritus (recovered/resolved), generalized rash (recovered/resolved), wheezing (recovered/resolved), shortness of breath (recovered/resolved), throat tightness (recovered/resolved), hoarse voice (recovered/resolved), cough (recovered/resolved), vomiting (recovered/resolved) and diarrhea (recovered/resolved). The investigator considered that there was a reasonable possibility that the anaphylaxis, generalized pruritus, generalized rash, wheezing, shortness of breath, throat tightness, hoarse voice, cough, vomiting and diarrhea may have been caused by Flu seasonal TIV Dresden.
