Background

Definitions of medication overuse headache have changed over time.

Objective

To evaluate the clinical characteristics of medication overuse headache patients admitted for inpatient withdrawal therapy over a period of 32 years.

Methods

We included all patients with medication overuse headache treated from 1 January 1984 to 31 December 2015. We obtained all data from the medical reports and defined three periods, P1 (1984–1993), P2 (1994–2003), and P3 (2004–2015). The p-value adjusted for multiple comparisons was set to 0.005.

Results

Within 32 years, a total of 787 patients accounted for 904 admissions for MOH. From P1 to P3, the proportion of patients with preexisting migraine increased from 44.3% to 53.3% (chi2 = 9.0, p = 0.01) and that with preexisting tension-type headache decreased from 47.9% to 34.6% (chi2 = 9.3, p < 0.01). The median time since onset of headache and medication overuse headache decreased from 20 to 15 years (p < 0.001) and from 3 to 2 years (p < 0.001). The median cumulative number of single doses decreased from 120 to 90 per month (p = 0.002). Overuse of triptans, non-opioid analgesics, and opioids increased, whereas overuse of ergotamines decreased over time (p < 0.001 for all tests). The use of prophylactic medication before admission increased from 8.3% to 29.9% (chi2 = 89.5, p < 0.001).

Conclusion

This retrospective study in a large number of patients with medication overuse headache admitted for inpatient withdrawal therapy over a period of 32 years shows a trend towards changes in the preexisting headache type, a decrease in the time since onset of headache and medication overuse headache, a decrease in the number of drug doses used per month, changes in the type of drugs overused, and an increase in, but still low rate, of prophylactic medication prior to admission.

在 32 年的时间里,787 名住院治疗的患者出现药物过度使用性头痛。

背景

药物过度使用性头痛的定义随着时间的推移而改变。

客观的

评估在 32 年内接受住院戒断治疗的药物过度使用性头痛患者的临床特征。

方法

我们纳入了 1984 年 1 月 1 日至 2015 年 12 月 31 日治疗的所有药物过度使用性头痛患者。我们从医学报告中获取所有数据并定义了三个时期,P1(1984-1993)、P2(1994-2003)和 P3(2004-2004- 2015)。针对多重比较调整的p值设置为 0.005。

结果

在 32 年内,共有 787 名患者占 MOH 的 904 人入院。从 P1 到 P3,预先存在偏头痛的患者比例从 44.3% 增加到 53.3%(chi 2  = 9.0,p  = 0.01),预先存在紧张型头痛的患者比例从 47.9% 下降到 34.6%(chi 2  = 9.3,p  < 0.01)。头痛和药物过度使用头痛发作后的中位时间从 20 年减少到 15 年(p  < 0.001),从 3 年减少到 2 年(p  < 0.001)。单次剂量的中位累积次数从每月 120 次减少到 90 次(p  = 0.002)。曲坦类药物、非阿片类镇痛药和阿片类药物的过度使用增加,而麦角胺的过度使用随着时间的推移而减少。 对于所有测试,p < 0.001)。入院前预防性药物的使用从 8.3% 增加到 29.9%(chi 2  = 89.5,p  < 0.001)。

结论

这项在 32 年内接受住院戒断治疗的大量药物过度使用性头痛患者的回顾性研究显示,先前存在的头痛类型有变化的趋势,自头痛发作和药物过度使用性头痛以来的时间减少,这是每月使用的药物剂量减少,过度使用的药物类型发生变化,入院前预防性药物的使用率有所增加,但仍然很低。
