Abstract
OBJECTIVE: Interstitial lung diseases (ILDs) are diverse pulmonary disorders marked by diffuse lung inflammation and fibrosis. The variability in characteristics and treatment approaches complicates diagnosis and management. In advanced cases requiring transplantation, determining indications and selecting suitable candidates presents additional challenges. METHODS: Of all patients with non-IPF ILD between December 2016 to December 2022 were analyzed retrospectively. Patients were categorized into two groups: transplanted patients and deceased patients on the waiting list. Clinical data and survival outcomes were compared between groups. RESULTS: Of the 43 patients, 20 underwent lung transplantation while 23 died awaiting transplantation. Waiting list mortality was 53.4%, with median waiting times similar between groups (3 months for transplant patients and 6 months for those on the waiting list). There were no significant differences between groups in age, gender, height, BMI, 6-minute walk test (6MWT), or forced vital capacity (FVC). The prevalence of pulmonary hypertension (PH) was 76.7% in right heart catheterizations, similar in both groups. One single and 19 bilateral lung transplants were performed. Overall, 13 of the 20 patients survived to discharge from the hospital. One-year mortality was 7/20 (35%). The median follow-up was 34 months, with a 1-year conditional survival of 90.9% at 3 years and 70.7% at 5 years. CONCLUSIONS: This study underscores the importance of further research into non-IPF ILDs. Lung transplantation remains a viable option that can significantly enhance both the quality and longevity of life for patients with advanced ILD.
