title: Telomeropathies: an emerging spectrum of disorder with important implications for patients with interstitial lung disease.
abstract: Growing evidence demonstrates that a number of clinical disorders may be related to genetic defects in telomeres replication and extensions. Overall, these syndromes are referred to as telomeropathies or telomeres disorders or syndromes; they are increasingly being identified. In adulthood, idiopathic pulmonary fibrosis (IPF) is the most common symptom of telomeropathy. IPF is a progressive and fatal disease characterized by scarring of the lungs that thickens the interstitium ultimately leading to irreversible respiratory failure. Starting from this basis, the present review analyzes and discusses the findings of a relevant paper by Gautam George and colleagues from the Division of Pulmonary and Critical Care Medicine at Brigham and Women's Hospital and Harvard Medical School in Boston (USA) recently appeared on the prestigious journal CHEST. In a cohort of patients addressed to lung transplantation, authors were able to demonstrate that subclinical bone marrow and liver abnormalities can be seen in patients with interstitial lung disease (ILD) and short telomeres, in some cases in the absence of clinically significant abnormalities in peripheral blood count and liver function tests. This observation sustains the rationale for further studies aimed to validate telomere length testing as a useful parameter as part of the evaluation for transplant candidacy. A deeper clarification of the complex link between IPF and short telomeres and telomeropathies is required for a new ILD classification, aimed to a fullpersonalized approach to the disease.
