RT Journal Article SR Electronic T1 Treatment of lethal pertussis vaccine reaction with histamine H1 antagonists JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 1068 OP 1068 DO 10.1212/WNL.37.6.1068 VO 37 IS 6 A1 Peroutka, Stephen J. A1 Kitamura, Kumiko A1 Lim, Mae A1 Steinman, Lawrence YR 1987 UL http://n.neurology.org/content/37/6/1068.abstract AB We studied mortality after pertussis immunization in the mouse. Without treatment, 73 of 92 animals (80%) died after injection of bovine serum albumin (BSA) on day +7 of pertussis immunization. After pretreatment with 3 mg of cyproheptadine, 2 mg mianserin, or 2 mg clorpheniramine, only 5 of 105 animals (5%) died after receiving BSA on day +7 (I) <0.001). Blockade of histamine H1 receptors may reduce mortality in pertussis immunization-induced encephalopathy in mice.
