ABSTRACT

BACKGROUND: Patients with idiopathic pulmonary fibrosis (IPF) frequently have multiple comorbidities, which may influence survival but go under-recognised in clinical practice. We therefore report comorbidity, antifibrotic treatment use and survival of patients with IPF observed in the multi-national EMPIRE registry. METHODS: For this prospective IPF cohort, demographics, comorbidities, survival and causes of death were analysed. Comorbidities were noted by the treating physician based on the patient's past medical history or as reported during follow-up. Comorbidities were defined as prevalent when noted at enrolment, or as incident when recorded during follow-up. Survival was analysed by Kaplan-Meier estimates, log-rank test, and Cox proportional hazards models. Hazard ratios (HR) were adjusted for gender, age, smoking status and FVC at enrolment. RESULTS: A population of 3,580 patients with IPF from 11 Central and Eastern European countries was followed every 6 months for up to 6 years. At enrolment, 91.3% of patients reported at least one comorbidity, whereas more than one-third (37.8%) reported four or more comorbidities. Five-year survival was 53.7% in patients with no prevalent comorbidities, whereas it was 48.4%, 47.0%, 43.8% and 41.1% in patients with 1, 2, 3 and ≥ 4 comorbidities, respectively. The presence of multiple comorbidities at enrolment was associated with significantly worse survival (log-rank test P = 0.007). Adjusted HRs indicate that risk of death was increased by 44% in patients with IPF reporting ≥ 4 comorbidities at baseline compared with no comorbidity (P = 0.021). The relationship between number of comorbidities and decreased survival was also seen in patients receiving antifibrotic treatment (63% of all patients; log-rank test P < 0.001). Comorbidity as cause of death was identified in at least 26.1% of deaths. CONCLUSIONS: The majority of patients with IPF demonstrate comorbidities, and many have comorbidity-related deaths. Increasing numbers of comorbidities are associated with worse survival; and this pattern is also present in patients receiving antifibrotic therapy.

ABSTRACT

More than 380 medications are known to cause pulmonary toxicity. Selected drugs that are important causes of pulmonary toxicity fall into the following classes: cytotoxic, cardiovascular, anti-inflammatory, antimicrobial, illicit drugs, miscellaneous. The adverse reactions can involve the pulmonary parenchyma, pleura, the airways, pulmonary vascular system, and mediastinum. Drug-induced lung diseases have no pathognomonic clinical, laboratory, physical, radiographic or histological findings. A drug-induced lung disease is usually considered a diagnosis of exclusion of other diseases. The diagnosis of drug-mediated pulmonary toxicity is usually made based on clinical findings. In general, laboratory analyses do not help in establishing the diagnosis. High-resolution computed tomography scanning is more sensitive than chest radiography for defining radiographic abnormalities. The treatment of drug-induced lung disease consists of immediate discontinuation of the offending drug and appropriate management of the pulmonary symptoms. Glucocorticoids have been associated with rapid improvement in gas exchange and reversal of radiographic abnormalities. Before starting any medication, patients should be educated about the potential adverse effects of the drug. Amiodarone is an antiarrhythmic agent used in the treatment of many types of tachyarrhythmia. Amiodarone-caused pulmonary toxicity is a well-known side effect (complication) of this medication. The incidence of amiodarone-induced lung disease is approximately 5-7%.
