An association between idiopathic pulmonary fibrosis (IPF) and advancing age is suspected since IPF occurs primarily in patients over 60 years of age. Though, little is known about the disease in the elderly. The aim of this study was to characterize elderly IPF patients using data from the longitudinal, German-wide INSIGHTS-IPF registry. Patients were grouped into elderly (≥75 years) and nonelderly IPF (<75 years) at the time of enrollment into the study. Baseline clinical characteristics, comorbidities, health related quality of life (HRQoL), medical therapy and survival were compared between age groups. Effects of antifibrotic therapy on forced vital capacity (FVC) were analyzed over 24 months. Of 1,009 patients, 350 (34.7%) were ≥75 years old. Elderly IPF patients compared to younger patients had a higher number of comorbidities (3.6 ± 2.5 vs. 2.8 ± 2.3; < 0.001). The mean ± SD EQ-5D score (0.64 ± 0.21 vs. 0.69 ± 0.21; = 0.005), and the overall WHO-5 score (13.1 ± 5.9 vs. 14.3 ± 6.0; = 0.015) were significantly lower while the UCSD-SOBQ (52.6 ± 31.2 vs. 45.5 ± 31.2; = 0.030) was significantly higher in elderly patients, indicating a more impaired HRQoL and more breathlessness. At baseline, 55.4% of elderly and 56.8% of nonelderly patients with IPF were treated with antifibrotic therapy ( = 0.687). For FVC decline after initiation of antifibrotic therapy, there was neither a significant difference between age groups at the different time points over 24 months (beta: 0.41; 95%-CI: -0.98 to 1.81; = 0.563) nor over the whole course of time (beta: -0.05; 95%-CI: -0.20 to 0.09; = 0.478). All-cause mortality was higher in elderly patients (49.1 vs. 37.9%; HR 1.65; 95%-CI 1.36-2.00; < 0.001). Antifibrotic therapy was associated with improved survival in IPF patients, independent from age (<75 years: beta 0.76; 95%-CI: 0.59-0.99; = 0.049; ≥75 years: beta 0.71; 95%-CI: 0.51-0.98; = 0.043). In real life, a significant proportion of IPF patients are ≥75 years old, characterized by higher number of comorbidities and global reduced HRQoL. However, the effect of an antifibrotic therapy was similar between age groups and associated with a survival benefit emphasizing the importance for an early antifibrotic therapy in IPF, independent from age.
由于特发性肺纤维化(IPF)主要发生在60岁以上的患者中,因此怀疑其与年龄增长有关。然而,对于老年患者的这种疾病知之甚少。本研究的目的是利用德国全国性的纵向INSIGHTS-IPF注册中心的数据,对老年IPF患者进行特征描述。在研究入组时,将患者分为老年组(≥75岁)和非老年IPF组(<75岁)。比较了年龄组之间的基线临床特征、合并症、健康相关生活质量(HRQoL)、药物治疗和生存率。分析了抗纤维化治疗对用力肺活量(FVC)在24个月内的影响。在1009例患者中,350例(34.7%)年龄≥75岁。与年轻患者相比,老年IPF患者的合并症数量更多(3.6±2.5对2.8±2.3;P<0.001)。老年患者的平均±标准差EQ-5D评分(0.64±0.21对0.69±0.21;P=0.005)和总体WHO-5评分(13.1±5.9对14.3±6.0;P=0.015)显著更低,而UCSD-SOBQ评分(52.6±31.2对45.5±31.2;P=0.030)显著更高,表明老年患者的HRQoL受损更严重,呼吸急促更明显。基线时,55.4%的老年IPF患者和56.8%的非老年IPF患者接受了抗纤维化治疗(P=0.687)。在开始抗纤维化治疗后,FVC下降在24个月内的不同时间点,年龄组之间均无显著差异(β:0.41;95%置信区间:-0.98至1.81;P=0.563),在整个时间段内也无显著差异(β:-0.05;95%置信区间:-0.20至0.09;P=0.478)。老年患者的全因死亡率更高(49.1%对37.9%;HR 1.65;95%置信区间1.36-2.00;P<0.001)。抗纤维化治疗与IPF患者生存率提高相关,与年龄无关(<75岁:β 0.76;95%置信区间:0.59-0.99;P=0.049;≥75岁:β 0.71;95%置信区间:0.51-0.98;P=0.043)。在现实生活中,相当一部分IPF患者年龄≥75岁,其特征是合并症数量更多,整体HRQoL降低。然而,抗纤维化治疗在年龄组之间的效果相似,并与生存获益相关,强调了在IPF中早期抗纤维化治疗的重要性,与年龄无关。
