Abstract

Background

RSV is a leading cause of ARI, including CAP, in older adults. Data available often underestimate RSV-related ARI incidence. We estimated RSV-related ARI hospitalization incidence from a prospective CAP study, adjusting for undiagnosed RSV infections due to nasopharyngeal/nasal swab testing only.

Methods

Active surveillance of adult CAP hospitalizations in Germany was conducted between 2021–2023. Nasopharyngeal/nasal swabs were RSV-tested, and age-group specific proportions were applied to calculate RSV-related CAP incidence. This was divided by the CAP proportions among RSV-related ARI hospitalizations (from multispecimen study) to extrapolate RSV-related ARI rates.

Results

Among 1040 radiologically confirmed CAP cases, 3.7% tested RSV-positive via nasopharyngeal/nasal swab, corresponding to 7.8% after adjusting for underdetection. For 18–59 and ≥60 years, adjusted RSV-related CAP hospitalization rates (95% CI) were 4.9 (1.8–10.9) and 115.6 (78.8–163.6); adjusted RSV-related ARI hospitalization rates were 19.8 (6.8–50.1) and 401.6 (260.7–609.3) per 100,000, respectively. Within 30 days of an RSV-related CAP admission, 18.2% of those ≥65 years died, and 11.1% and 36.4% had cardiovascular events among those 18–64 and ≥65 years, respectively.

Conclusions

Older adults in Germany experience a high burden of RSV-related ARI hospitalizations, including CAP, underscoring RSV vaccination’s potential utility for this population.

包括CAP在内的ARIs的rsv相关住院发生率：来自德国前瞻性ThEpiCAP研究的数据。

背景：RSV是老年人急性呼吸道感染（包括急性呼吸道感染）的主要原因。现有数据往往低估了呼吸道合胞病毒急性呼吸道感染的发病率。我们从一项前瞻性CAP研究中估计了RSV相关的ARI住院发生率，调整了仅因鼻咽/鼻拭子检测而未确诊的RSV感染。方法：在2021-2023年期间对德国成人CAP住院进行主动监测。对鼻咽/鼻拭子进行rsv检测，并采用年龄组特定比例计算rsv相关的CAP发病率。将其除以与呼吸道合胞病毒相关的ARI住院患者的CAP比例（来自多样本研究），以推断与呼吸道合胞病毒相关的ARI发病率。结果：1040例CAP放射学确诊病例中，经鼻咽/鼻拭子检测rsv阳性的占3.7%，剔除未检出因素后为7.8%。对于18-59岁和≥60岁的患者，校正rsv相关CAP住院率（95% CI）分别为4.9（1.8-10.9）和115.6（78.8-163.6）。调整后的rsv相关ARI住院率分别为19.8(6.8-50.1)/ 10万和401.6(260.7-609.3)/ 10万。在rsv相关的CAP入院30天内，≥65岁的患者中有18.2%死亡，18-64岁和≥65岁的患者中分别有11.1%和36.4%发生心血管事件。结论：德国老年人经历了与呼吸道合胞病毒相关的ARI住院的高负担，包括CAP，强调了呼吸道合胞病毒疫苗接种对这一人群的潜在效用。
