继发于肥大细胞疾病的全身过敏反应

定义

继发于肥大细胞疾病的过敏性休克症状是由于肥大细胞介质释放过多，特别是组胺，可能包括瘙痒和潮红、腹痛、腹泻、呼吸困难、心动过速或深度低血压。它既发生在儿童也发生在成人，但即使没有荨麻疹色素病变，在成人中也会发生。基础类胰蛋白酶水平一直很高。在膜翅目螫伤后和术前围手术期，已经描述过致命的过敏性休克。

Symptoms of anaphylaxis secondary to mast cell disorders result from excessive mast cell mediator release, especially histamine, and may include pruritus and flushing, abdominal pain, diarrhea, dyspnoea, tachycardia, or profound hypotension. It happens in both children and adults, but in adults it can occur even without urticaria pigmentosa lesions. Levels of basal tryptase are constantly high. Fatal anaphylaxis has been described following hymenoptera stings and in the preoperative period.
