巨细胞动脉炎

巨细胞动脉炎(Giant cell arteritis,GCA),又称颞动脉炎,为主要进犯大型血管的发炎性疾病[4][7]。症状包含头痛、太阳穴疼痛、流感样症状英语flu-like symptoms复视、张口困难(jaw claudication)[3]。并发症包含眼动脉阻塞,造成视力受损主动脉剥离,以及主动脉瘤等等[4]。巨细胞动脉炎与风湿性多发性肌痛症英语polymyalgia rheumatica[4]

巨细胞动脉炎的详细致病原因目前尚未阐明[2]。大型动脉的血管滋养管发炎可能为潜在致病机转[4]。该疾病主要进犯头颈部的血管,但有时也会进犯胸部的血管[4][8]。诊断需依据症状、抽血检查,及医学影像进行,若须确诊必须进行浅颞动脉活体组织切片[4]。然而有约10%患者的颞动脉是正常的[4]

治疗上通常会给予高剂量的糖皮质激素,如强的松(prednisone)或泼尼松龙(prednisolone)[4]。症状缓解后,每两周可以减少约10-20%的剂量[4]。减药到一定剂量后,则需减缓减药速度[4]。为了避免类固醇的副作用,治疗上也可以配合双磷酸盐类英语bisphosphonates避免骨质流失,或是氢离子帮浦阻断剂减少肠胃道症状[4]

巨细胞动脉炎通常只会在50岁以上发生,其中更常见于70岁以上的人[4]。约有15,000分之一的50岁以上患者可能发生[2]。女性[4]北欧人又较其他族群容易发生[5]。患者的预期寿命通常不受影响[4]。该病于1890年首次为人记述[1]
