Description
Summary:Abstract Background Advances in the field of genetics of interstitial lung diseases (ILDs) have led to the recent consensus statements made by expert groups. International standards for genetic testing in ILD have not yet been established. We aimed to examine current real-world strategies employed by pulmonologists working with familial ILD. Methods A panel of pulmonologists with expertise in ILD developed an international survey aimed at clinicians working with ILD. The survey consisted of 74 questions divided into eight topics: characteristics of respondents, diagnosis, screening of first-degree relatives, screening tools, genetic testing methods, lung transplantation, ethical concerns, and future needs. Results Overall, 237 pulmonologists from 50 countries participated. A family history of ILD was asked for by 91% of respondents while fewer asked for symptoms related to telomere disorders. Respondents stated that 59% had access to genetic testing, and 30% to a genetic multidisciplinary team (MDT). Many respondents were unaware of specific genetic testing methods. Pathogenic genetic variants were seen as a potential contraindication for lung transplantation in 6–8% of respondents. Genetic screening of relatives was supported by 80% of respondents who indicated insufficient evidence and a lack of formal guidelines for genetics and ILD. Only 16% had a standardized program. Conclusion Most pulmonologists ask for a family history of ILD and recommend genetic testing for ILD and screening in relatives but have limited knowledge of specific tests and access to genetic MDT. Evidence-based guidelines to inform patients, relatives, and physicians are still warranted.
