Background: Sex is an important part of life for many adults, yet sexual function may be impacted by chronic respiratory diseases such as pulmonary fibrosis (PF). This multinational study sought to characterise the impact of PF on sex and sexual function, using mixed quantitative and qualitative methodology.
Methods: We analysed data from a patient registry, a clinical study, an online survey and patient interviews to accomplish our objective and develop a conceptual framework for describing the effects of PF on sex-related quality of life. These cohorts used three distinct questionnaires, University of California, San Diego Shortness of Breath Questionnaire (UCSD-SOBQ), Sheffield Profile for Assessment and Referral to Care (SPARC) questionnaire, and Changes in Sexual Function Questionnaire (CSFQ), to assess sexual dysfunction, respectively. Individual patient interviews were conducted and qualitatively evaluated using thematic analysis.
Results: Dyspnoea with sexual activity affected 2054/2759 (74%) of registry patients, associated with male sex, lower forced vital capacity (FVC) % predicted, lower diffusing capacity of the lung for carbon monoxide (DLCO) % predicted and worse cough. Distress due to the effect of PF on their sex life was reported in 52/225 (23%) of the clinical cohort, associated with younger age, male sex, lower DLCO % predicted and worse cough. Sexual dysfunction was common, affecting 56/67 (83%) female and 63/73 (86%) male survey respondents. Qualitative analysis of patient interviews identified several themes, including sex life limitations, changes in interpersonal relationships and quality of life. All patients wanted to discuss sex with trusted healthcare providers.
Conclusions: In this multinational study, patients with PF reported engaging in sex and sexual activities but were adversely impacted by the effect of PF on their sex life, with both physical and psychological limitations. Sexual dysfunction was common, driven by multiple disease domains. Sexual health appears to be an important component of comprehensive patient care.

BACKGROUNDFEV1Q (Forced Expiratory Volume in 1 s Quotient) is a race-neutral expression of lung function. The validity and utility of FEV1Q across Global South populations has not been previously explored.METHODSWe conducted a post-hoc analysis of data from the Global Excellence in COPD Outcomes-1 (GECo1 and GECo2) studies in which a random age- and sex-stratified population of 10 709 people were recruited in Nepal, Peru and Uganda. The FEV1 first percentile (used to derive FEV1Q) was estimated in those with COPD by site and sex. We examined associations between FEV1Q, risk factors and respiratory morbidity. We estimated the rate of decline in FEV1Q. We evaluated the discriminative accuracy of FEV1Q in diagnosing COPD.FINDINGSThe first percentile FEV1 in those with COPD at 0·43 L in women and 0·52 L in men is similar to those previously used to calculate FEV1Q. Lower FEV1Q was associated with older age, lower socioeconomic status, shorter height, and greater smoking pack-years. We estimated that decline in FEV1Q with age was 0·65 (95%CI: 0·64; 0·67) units/10 years, more rapid in those continuing to smoke at 0·82 (95%CI: 0·77; 0·87) units/10 years. FEV1Q was lower in those with prior respiratory hospitalizations and impairment in daily activities due to respiratory disease, and associated with future hospitalization risk in the GECo2 study. Pre-bronchodilator FEV1Q had reasonable diagnostic accuracy for COPD (AUC 0·87(95%CI:0·85-0·88)), similar to pre-bronchodilator FEV1% predicted (AUC 0·88(95%CI:0·87-0·90)).INTERPRETATIONOur data support the validity and utility of FEV1Q as a race-neutral approach to lung function assessment in diverse settings, including the Global South where the burden of lung disease is greatest.FUNDINGThis study was funded by the Medical Research Council (grant MR/P008984/1) under a Global Alliance for Chronic Diseases call.

QUESTIONChronic lung allograft dysfunction (CLAD) is the leading cause of late graft failure after lung transplantation. Fibroblast activation protein (FAP) is selectively upregulated in activated fibroblasts under fibrotic conditions. We asked whether FAP expression is increased in chronic lung allograft dysfunction and whether it can serve as an early diagnostic marker.MATERIALS AND METHODSWe performed single-cell RNA sequencing on two murine orthotopic lung transplant models (C57BL/6→C57BL/10 and BALB/c→C57BL/6) and human lung tissue from five controls and five patients with CLAD. We quantified FAP expression by immunohistochemistry in transbronchial biopsies from 240 lung transplant recipients (62 with CLAD and 178 without CLAD). Receiver-operating characteristic curves determined an optimal FAP-positive area threshold. Kaplan-Meier analysis and Cox proportional hazards models assessed the association between FAP positivity and CLAD.RESULTSIn both murine and human single-cell data, FAP expression was confined to pathogenic fibroblast subsets and was significantly elevated in CLAD. In the clinical cohort, a threshold of 10.8 percent FAP-positive area discriminated chronic dysfunction with an area under the curve of 0.78 (95% CI, 0.72-0.85), sensitivity of 65%, and specificity of 84%. FAP positivity predicted shorter CLAD-free survival (p<0.0001) and overall survival (p=0.03). The hazard ratio for CLAD was 5.23 (95% CI, 3.11-8.82; p<0.001), remaining significant after multivariable adjustment (hazard ratio 5.43; 95% CI, 3.22-9.16; p<0.001).ANSWERFAP expression is elevated in CLAD and is associated with subsequent CLAD and survival. Tissue FAP may enable early risk stratification and inform clinical surveillance; however, given its moderate discrimination, prospective validation in multicenter cohorts is warranted.
