To investigate the potential association between statin use and giant cell arteritis (GCA) course.
Using the French National Health Insurance system, we included patients with incident GCA from the Midi-Pyrenees region, southern France, from January 2005 to December 2008 and randomly selected 6 controls matched by age, sex, and date of diagnosis. Statin exposure was compared between patients with GCA and their controls before GCA occurrence with a logistic regression. Influence of statin exposure on prednisone requirements during GCA course was explored with a Cox model, considering statin exposure as a time-varying variable.
The cohort included 103 patients (80 women, mean age 74.8 ± 9 yrs, mean followup 48.9 ± 14.8 mos), compared to 606 controls. Statin exposure (27.2% of patients with GCA and 23.4% of controls) was not associated with GCA occurrence (adjusted OR 1.2, 95% CI 0.76-1.96; p = 0.41). Diabetes mellitus was significantly associated to GCA occurrence (adjusted OR 0.38, 95% CI 0.11-0.72; p = 0.008). After diagnosis, exposure to statins up to 20 months was associated with maintenance while taking low prednisone doses (p = 0.01).
Statin exposure was not associated with GCA occurrence in the general population. However, exposure to statins up to 20 months may favor a quicker corticosteroid tapering. Based on those results, statin effect on GCA course should not be definitively ruled out.
探讨他汀类药物使用与巨细胞动脉炎(GCA)病程之间的潜在关联。
利用法国国家医疗保险系统,我们纳入了2005年1月至2008年12月来自法国南部米迪 - 比利牛斯地区的初发GCA患者,并随机选取6名年龄、性别和诊断日期匹配的对照。采用逻辑回归比较GCA患者及其对照在GCA发病前的他汀类药物暴露情况。使用Cox模型探讨他汀类药物暴露对GCA病程中泼尼松需求的影响,将他汀类药物暴露视为一个随时间变化的变量。
该队列包括103例患者(80名女性,平均年龄74.8±9岁,平均随访48.9±14.8个月),对照为606名。他汀类药物暴露(GCA患者中为27.2%,对照中为23.4%)与GCA发病无关(校正比值比1.2,95%置信区间0.76 - 1.96;p = 0.41)。糖尿病与GCA发病显著相关(校正比值比0.38,95%置信区间0.11 - 0.72;p = 0.008)。诊断后,长达20个月的他汀类药物暴露与低剂量泼尼松维持治疗相关(p = 0.01)。
在一般人群中,他汀类药物暴露与GCA发病无关。然而,长达20个月的他汀类药物暴露可能有利于更快地减少皮质类固醇用量。基于这些结果,不应完全排除他汀类药物对GCA病程的影响。
