title: Anaphylactoid reactions with intraperitoneal cisplatin.
abstract: OBJECTIVE
  To report the occurrence of anaphylactoid reactions to intraperitoneal cisplatin in 3 patients.
  
  
  METHODS
  While conducting a protocol evaluating the efficacy of intraperitoneal cisplatin and hyperthermia in the treatment of recurrent ovarian cancer, 3 patients were noted to exhibit anaphylactoid reactions. A 43-year-old woman received cisplatin 60 mg/m2 in 15 minutes during her sixth cycle of therapy. She developed pruritus, edema, and urticaria over both hands. The reaction subsided after treatment with diphenhydramine and dexamethasone. A 57-year-old woman received 400 mL (62.4 mg) of a cisplatin solution concentrated to deliver cisplatin 100 mg/m2 during her first attempted therapy. At this point, she developed whole body urticaria and pruritus with edema of the extremities. The reaction was aborted with diphenhydramine and dexamethasone. Despite premedication with dexamethasone prior to a second attempt at therapy, she again experienced similar symptoms after receiving 500 mL (78 mg) of cisplatin solution. A 55-year-old woman received 2 cycles of therapy with cisplatin 100 mg/m2 without difficulty. During her third cycle, she again received cisplatin 100 mg/m2 over 30 minutes and developed palmar pruritus, urticaria, and edema. Symptomatology resolved with diphenhydramine. Despite premedication with diphenhydramine and dexamethasone, she experienced generalized pruritus and urticaria, as well as headache and chest pain/tightness, after her next infusion. For both the second and third patients, symptomatology failed to resolve until the intraperitoneal cisplatin solution was withdrawn.
  
  
  CONCLUSIONS
  Anaphylactoid reactions have been described previously with cisplatin administration. No dose-rate effect has been reported, however. We observed 5 reactions in 3 patients that appear to be related to a high dose-infusion time ratio, indicating that dose and rate of infusion may be important factors in precipitating anaphylactoid reactions with cisplatin.
  
  
  CONCLUSIONS
  We conclude that a high dose combined with a short infusion time increases the risk of anaphylactoid reactions with the administration of intraperitoneal cisplatin. There was no indication that the increase in anaphylactoid reactions was associated with the use of hyperthermia.
