低剂量甲氨蝶呤 (MTX) 引起中枢神经系统 (CNS) 毒性的报道很少,报道的症状主要包括头晕和头痛。我们回顾了 25 名连续接受低剂量 MTX 治疗的患者的记录,发现其中 5 名患者自发报告了不愉快的颅部感觉、情绪改变或记忆障碍。 3 名患者 5 次再次服用 MTX,导致所有病例中枢神经系统症状复发。 CNS 毒性是 2 名患者停止使用 MTX 的唯一原因。这 5 名患者与 20 名无 CNS 毒性的患者在年龄(平均 68 岁与 50 岁)和基线血清肌酐水平(1.3 mg/dl 对 0.9 mg/dl)方面存在差异,但 MTX 的每周剂量(12 mg 对 16 mg)则没有差异。这些结果表明,中枢神经系统毒性比之前报道的更为常见,特别是在患有轻度肾功能不全的老年患者中。
Central nervous system (CNS) toxicity from low-dose methotrexate (MTX) has been reported rarely, and reported symptoms consist primarily of dizziness and headache. We reviewed the records of 25 consecutive patients treated with low-dose MTX, and found 5 who had spontaneously reported unpleasant cranial sensations, mood alteration, or memory impairment. Rechallenge with MTX on 5 occasions in 3 patients led to recurrent CNS symptoms in all cases. CNS toxicity was the sole reason for discontinuation of MTX in 2 patients. These 5 patients differed from the 20 without CNS toxicity in age (mean 68 versus 50) and baseline serum creatinine level (1.3 mg/dl versus 0.9 mg/dl), but not in weekly dosage of MTX (12 mg versus 16 mg). These results suggest that CNS toxicity is more common than previously reported, particularly in older patients with mild renal insufficiency.
