睾酮缺乏在患有慢性阻塞性肺病 (COPD) 的男性中很常见,并且可能会加剧病情。研究表明,睾酮替代疗法 (TRT) 可能对慢性阻塞性肺病 (COPD) 男性的呼吸系统结局产生有益影响。然而,迄今为止,还没有大规模的具有全国代表性的研究检验过这种关联。该研究的目的是评估 TRT 是否可以降低患有慢性阻塞性肺病的中老年男性因呼吸道疾病住院的风险。我们进行了两项回顾性队列研究。首先,使用 Clinformatics Data Mart(美国最大的商业保险人群之一的数据库),我们检查了 450 名年龄在 40-63 岁、患有慢性阻塞性肺病 (COPD) 的男性,他们在 2005 年至 2014 年之间开始了 TRT。其次,使用国家 5% 医疗保险数据库,我们检查了 253 名患有慢性阻塞性肺病 (COPD) 的男性,他们在 2008 年到 2013 年之间开始了 TRT。双重差分 (DID) 统计模型,用于比较平行时间段内 TRT 用户与匹配的 TRT 非用户的呼吸前和呼吸后住院率。 DID 分析显示,与非使用者相比,TRT 使用者的呼吸系统住院率相对下降幅度更大。具体而言,与不使用 TRT 的中年患者相比,中年 TRT 使用者的呼吸系统住院治疗减少了 4.2%(-2.4 减少 vs. 1.8 增加;p = 0.03);与未使用 TRT 的患者相比,老年 TRT 使用者的呼吸系统住院治疗减少了 9.1%(减少 -0.8 对比增加 8.3;p = 0.04)。这些发现表明 TRT 可能会减缓 COPD 患者的疾病进展。未来的研究应该在更大的患者群体中检验这种关联,特别关注特定的生物学途径。
Testosterone deficiency is common in men with chronic obstructive pulmonary disease (COPD) and may exacerbate their condition. Research suggests that testosterone replacement therapy (TRT) may have a beneficial effect on respiratory outcomes in men with COPD. To date, however, no large-scale nationally representative studies have examined this association. The objective of the study was to assess whether TRT reduced the risk of respiratory hospitalizations in middle-aged and older men with COPD. We conducted two retrospective cohort studies. First, using the Clinformatics Data Mart—a database of one of the largest commercially insured populations in the United States—we examined 450 men, aged 40–63 years, with COPD who initiated TRT between 2005 and 2014. Second, using the national 5% Medicare database, we examined 253 men, aged ≥66 years, with COPD who initiated TRT between 2008 and 2013. We used difference-in-differences (DID) statistical modeling to compare pre- versus post-respiratory hospitalization rates in TRT users versus matched TRT nonusers over a parallel time period. DID analyses showed that TRT users had a greater relative decrease in respiratory hospitalizations compared with nonusers. Specifically, middle-aged TRT users had a 4.2% greater decrease in respiratory hospitalizations compared with nonusers (−2.4 decrease vs. 1.8 increase; p = 0.03); and older TRT users had a 9.1% greater decrease in respiratory hospitalizations compared with nonusers (−0.8 decrease vs. 8.3 increase; p = 0.04). These findings suggest that TRT may slow disease progression in patients with COPD. Future studies should examine this association in larger cohorts of patients, with particular attention to specific biological pathways.
