Corticosteroids, especially dexamethasone, play a critical role in chemotherapy for pediatric hematological malignancies. We previously observed that patients with complaints of headache or photophobia during corticosteroid administration had high intraocular pressure (IOP).
We measured IOP during corticosteroid administration in 15 patients with acute leukemia or lymphoma undergoing treatment at our institution from January 2016 to December 2018. IOP was measured by an ophthalmologist within seven days of the initiation of standard dose of corticosteroid, which was defined as 60 mg/m /day for prednisolone and 10 mg/m /day for dexamethasone.
Fifteen patients received 52 courses of chemotherapy containing corticosteroids. IOP exceeded 21 mmHg among 13 patients in 28 courses. Twelve of the 13 patients were administered topical treatment, and six of the 12 patients needed additional diuretic agents. IOP during the chemotherapy courses containing dexamethasone was significantly higher compared with IOP during the chemotherapy courses containing prednisolone. Only two patients complained of symptoms, such as headache and photophobia, and one of the two patients underwent trabeculotomy. Funduscopic findings were normal in all patients. There was a dose-associated decrease in IOP with reduction of dexamethasone dose.
IOP should be measured during administration of substantial corticosteroid doses even in patients with no symptoms. Further investigations regarding the level of IOP for intervention need to be conducted.
皮质类固醇,尤其是地塞米松,在儿科血液系统恶性肿瘤的化疗中起着关键作用。我们之前观察到,在皮质类固醇给药期间出现头痛或畏光症状的患者眼压(IOP)较高。
我们在 2016 年 1 月至 2018 年 12 月期间对我院收治的 15 例急性白血病或淋巴瘤患者在接受皮质类固醇治疗期间进行了 IOP 测量。IOP 由眼科医生在开始使用标准剂量皮质类固醇后的七天内测量,定义为泼尼松龙 60mg/m2/天,地塞米松 10mg/m2/天。
15 例患者接受了 52 次含皮质类固醇的化疗。在 28 次化疗中,13 例患者中有 13 例的 IOP 超过 21mmHg。13 例患者中有 12 例接受了局部治疗,其中 6 例需要额外的利尿剂。含地塞米松的化疗课程中的 IOP 明显高于含泼尼松龙的化疗课程中的 IOP。只有两名患者出现头痛和畏光等症状,其中一名患者接受了小梁切开术。所有患者眼底检查均正常。随着地塞米松剂量的减少,IOP 呈剂量相关下降。
即使在无症状患者中,也应在给予大剂量皮质类固醇时测量 IOP。需要进一步研究干预的 IOP 水平。
