Background: Chronic lung disease predisposes to serious consequences of respiratory viruses. While increasing influenza immunization rates in older adults signals an awareness of the impact of influenza, children with asthma are infrequently immunized. While respiratory syncytial virus (RSV) is recognized as an important target of vaccine development for infants, its impact on adults is underappreciated.
Methods: We performed a retrospective cohort study to estimate rates of hospitalizations, deaths, outpatient visits, and antibiotic courses due to influenza and RSV in persons with chronic lung disease in the Tennessee Medicaid program from 1995 to 1999. Differences between study event rates when influenza was cocirculating with RSV and event rates when RSV was circulating alone were used to calculate influenza-attributable morbidity. Differences in rates when RSV was circulating alone and during summer months were calculated to assess the effect of RSV.
Results: Influenza- and RSV-associated hospitalizations were highest at the extremes of age. There were an estimated 8 and 23 hospitalizations per 1000 children younger than 5 years annually due to influenza and RSV, respectively. There were 23 and 18 hospitalizations, as well as 2 and 5 deaths per 1000 persons 65 years or older annually due to influenza and RSV, respectively. Both viruses were associated with an excess of outpatient visits in children, and antibiotic prescriptions in all age groups.
Conclusion: Among persons with chronic lung disease, influenza virus and RSV accounted for 15% to 33% of acute respiratory hospitalizations in children, 7% to 9% of such hospitalizations in adults, and 9% of deaths in those 65 years or older.

Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial lung disease with a poor prognosis. Its non-specific clinical symptoms make accurate prediction of disease progression challenging. This study aimed to develop molecular-level prognostic models to personalize treatment strategies for IPF patients.

Ataxia-telangiectasia (A-T) is an ultrarare autosomal recessive disorder and occurs in all racial and ethnic backgrounds. Clinically, children and young people with A-T are affected by sinopulmonary infections, neurological deterioration with concomitant bulbar dysfunction, increased sensitivity to ionizing radiation, immunodeficiency, a decline in lung function, chronic liver disease, endocrine abnormalities, cutaneous and deep-organ granulomatosis, and early death. Pulmonary complications become more frequent in the second decade of life and are a leading cause of death in individuals with A-T.

Long-term survival after lung transplantation is limited due to chronic lung allograft dysfunction (CLAD), which encompasses two main phenotypes: bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS). Donor-derived cell-free DNA (dd-cfDNA) is a biomarker for (sub)clinical allograft injury and could be a tool for monitoring of lung allograft health across the (pre)clinical spectrum of CLAD. In this proof-of-concept study, we therefore assessed post-transplant plasma dd-cfDNA levels in 20 CLAD patients (11 BOS and 9 RAS) at three consecutive time points free from concurrent infection or acute rejection, during stable condition, preclinical CLAD, and established CLAD ( = 3 × 20 samples).

Background: In COPD patients with severe right-sided emphysema, complete major and incomplete minor fissure, implantation of one-way valves in both the right upper (RUL) and middle lobes (ML) is a possible approach for endoscopic lung volume reduction. The aim of this retrospective analysis was to evaluate the response to therapy and the complication rate at 90 days (90d-FU) after combined RUL-ML valve implantation.
Methods: This retrospective, monocentric study included all patients from the Thoraxklinik Heidelberg who underwent RUL-ML valve treatment between 2012 and 2023 with available follow-up data.
