Low serum IgA levels were found in patients taking phenytoin, together with evidence of depressed T cell function. There was no correlation between the dose or the serum level. A correlation was found, however, with HL-A status, patients with a low IgA showing increased frequency of HL-A2. It is suggested that epileptic patients with HL-A2 status are likely to develop IgA deficiency when given phenytoin.
服用苯妥英钠的患者血清免疫球蛋白A(IgA)水平较低,同时有T细胞功能受抑制的证据。剂量或血清水平之间无相关性。然而,发现与人类白细胞抗原(HL-A)状态相关,IgA水平低的患者HL-A2的频率增加。有人提出,具有HL-A2状态的癫痫患者服用苯妥英钠时可能会出现IgA缺乏。
