Fibrotic Lung Diseases

Progressive fibrosing interstitial lung disease (PF-ILD) describes a phenotypic subset of interstitial lung diseases characterized by progressive, intractable lung fibrosis. PF-ILD is separate from, but has radiographic, histopathologic, and clinical similarities to idiopathic pulmonary fibrosis. Two antifibrotic medications, nintedanib and pirfenidone, have been approved for use in patients with idiopathic pulmonary fibrosis. Recently completed randomized controlled trials have demonstrated the clinical efficacy of antifibrotic therapy in patients with PF-ILD. The validation of efficacy of antifibrotic therapy in PF-ILD has changed the treatment landscape for all of the fibrotic lung diseases, providing a new treatment pathway and opening the door for combined antifibrotic and immunosuppressant drug therapy to address both the fibrotic and inflammatory components of ILD characterized by mixed pathophysiologic pathways.

Background:There is no specific treatment for interstitial lung disease (ILD) secondary to Rheumatoid Arthritis (RA) other than the treatment of RA without extra-articular involvement. Current regimens usually include corticosteroid therapy with or without immunosuppressants (IS), there is no consensus for the treatment.Objectives:To analyze the different treatment regimens in a cohort of patients with ILD and RA in our clinical practice.Methods:Descriptive study of 57 patients treated in our Hospital (1/1/2018 until 12/31/2019) with a diagnosis of RA (ACR 2010 criteria) and secondary ILD.The most recent American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Society (ALAT) guidelines define three HRCT (High Resolution Computed Tomography) patterns of fibrosing lung disease in the setting of idiopathic pulmonary fibrosis (IPF): definite Usual Interstitial pneumonia (UIP) (traction bronchiectasis and honeycombing), possible UIP and inconsistent with UIP. The distinction between definite UIP and possible UIP in these to the presence or absence of honeycombing. Approved by the Ethics Committee.Quantitative variables are expressed as mean (SD) and dichotomous variables as percentages (%). Statistical analysis with SPSS version 21.Results:21 men and 36 women were included, with a mean age of 69 ± 10 years (mean ± SD), history of smoking (smokers 14%, non-smokers 43%, former smokers 42%). Clinical ILD at diagnosis (dyspnea 61%, dry cough 56%, crackling 70%, acropachy 7%). 84% were positive rheumatoid factor and 70% positive anticitrullinated protein antibody.Diagnosis of ILD by HRCT in 100% of patients with different patterns: defined UIP 26 (45%), probable UIP 2 (3%) and not UIP 29 (50%). The diagnosis of ILD was confirmed by biopsy in 12 patients.79% underwent (T) treatment prior to the diagnosis of ILD with glucocorticoids and disease-modifying drugs (DMARD). Among the traditional DMARDs used were: Methotrexate 68% (there were no cases of MTX pneumonitis), Leflunomide 47%, Hydroxychloroquine 26% and Sulfasalazine 21%. Biological therapy in 15 patients: Etanercept 19%, Adalimumab 5%, Infliximab 3% and Certolizumab 2%. Two patients presented an exacerbation and rapid progression of the ILD during the T with Etanercept with the final result of death.T with IS after the diagnosis of ILD in 80% of patients (Azathioprine 15, Rituximab 14, Abatacept 10, Tocilizumab 4, Sarilumab 1, Mofetil mycophenolate 1 and Cyclophosphamide 1).Two patients with defined UIP perform T with antifibrotic: 1st Nintedanib (INBUILD Trial, This article was published on September 29, 2019, at NEJM.org) 2nd Pirfenidone (initial diagnosis of IPF Idiopathic Pulmonary Fibrosis and subsequent of seropositive RA with UIP). Both improved greater than 10% in forced vital capacity (FVC) and diffusion capacity of the lung for carbon monoxide (DLCO) in the 6 months after onset of T.Conclusion:Our results, in general, agree with what is published in the literature. Prospective, multicentre and larger sample studies are necessary to better define which patients would benefit more from IS T or antifibrotic T (or if the antifibrotic should be added to the previous IS).Disclosure of Interests:None declared

IntroductionAntisynthetase syndrome (ASyS) is a rare autoimmune connective tissue disease (CTD), associated with autoantibodies targeting tRNA synthetase enzymes, that can present to respiratory (interstitial lung disease (ILD)) or rheumatology (myositis, inflammatory arthritis and systemic features) services. The therapeutic management of CTD-associated ILD and idiopathic pulmonary fibrosis (IPF) differs widely, thus accurate diagnosis is essential.MethodsWe undertook a retrospective, multicentre observational cohort study designed to (1) evaluate differences between ASyS-associated ILD with IPF, (2) phenotypic differences in patients with ASyS-ILD presenting to respiratory versus rheumatology services, (3) differences in outcomes between ASySassociated with Jo-1 versus non-Jo-1 autoantibodies and (4) compare long-term outcomes between these groups.ResultsWe identified 76 patients with ASyS-ILD and 78 with IPF. Patients with ASyS were younger at presentation (57 vs 77 years, p<0.001) with a female predominance (57% vs 33%, p=0.006) compared with IPF. Cytoplasmic staining on indirect immunofluorescence was a differentiating factor between ASyS and IPF (71% vs 0%, p<0.0001). Patients with ASyS presenting initially to respiratory services (n=52) had a higher prevalence of ASyS non-Jo-1 antibodies and significantly fewer musculoskeletal symptoms/biochemical evidence of myositis, compared with those presenting to rheumatology services (p<0.05), although lung physiology was similar in both groups. There were no differences in high-resolution CT appearances or outcomes in those with Jo-1 versus non-Jo-1 ASyS-ILD.ConclusionsExtended autoimmune serology is needed to evaluate for ASyS autoantibodies in patients presenting with ILD, particularly in younger female patients. Musculoskeletal involvement is common in ASyS (typically Jo-1 autoantibodies) presenting to rheumatology but the burden of ILD is similar to those presenting to respiratory medicine.

Abstract Background: Although cigarette smoking is a major risk factor for lung cancer, the incidence rate of lung cancer among non-smokers is notable. The etiology and potential mechanism of non-smoker lung cancer are worthy of further research. This study was designed to explore the collective effects of environmental factors and the relationship between environmental exposure index (EEI) and lung cancer among non-smokers by evaluating the joint effects among lung disease history, environmental factors, and family history of lung cancer without smoking confounders.Methods: A total of 767 never-smoked lung cancer cases and 767 sex- and age-matched controls were selected from the department of Thoracic Surgery and Respiratory Medicine of three hospitals in Fujian, China. We used two methods to develop the EEI according to 12 statistically significant environmental risk factors. Restricted cubic spline (RCS) was applied to analyze the non-linear relationship between EEI and lung cancer in non-smokers. Combined effects, additive interaction, and multiplicative interaction were assessed among lung disease history, EEI, and family history of lung cancer to estimate susceptibility to develop lung cancer.Results: Lung disease history, especially asthma, was significantly associated with an increased risk of lung cancer with an odds ratio (OR) for asthma history of 14.720 (95% CI: 1.877–115.449). Family history of lung cancer was related to susceptibility of lung cancer (OR = 3.347, 95% CI: 1.930–5.806). According to type of relatives and cancer, a parental or children’s history and a sibling’s history of lung cancer were significantly associated with an increased risk of lung cancer. The positive association between EEI and lung cancer was apparently stronger in those with lung disease history or family lung cancer history. Furthermore, there was a addictive interaction between EEI and lung disease history, and a possibly addictive interaction between EEI and family lung cancer history on development of lung cancer.Conclusions: There were combined effects among lung disease history, environmental exposures, and family history of lung cancer toward susceptibility to lung cancer in Chinese non-smokers. Non-smokers who had a family history of lung cancer were at higher risk of lung cancer than non-smokers who had lung disease history. Non-smokers with family cancer history may obtain benefits from removal of environmental exposures and active treatment of lung disease.

Pulmonary hypertension frequently complicates interstitial lung disease, where it is associated with a high mortality. Patients with this dual diagnosis often fare worse than those with pulmonary arterial hypertension (PAH) alone and respond poorly to standard PAH therapy, often dying of right ventricular (RV) failure. We hypothesize that nitric oxide synthase (NOS) uncoupling is important in the pathogenesis of interstitial lung disease-associated pulmonary hypertension, and this process can be abrogated by phosphodiesterase type 5 (PDE5) inhibition to improve pulmonary vascular remodeling and right ventricular function. Intratracheal bleomycin (4 U/kg) or saline control was administered to C57/BL6 mice after anesthesia. After recovery, animals were fed a diet of sildenafil (100 mg·kg−1·day−1) or vehicle for 2 wk when they underwent hemodynamic measurements, and tissues were harvested. Survival was reduced in animals treated with bleomycin compared with controls and was improved with sildenafil (100.0 vs. 73.7 vs. 84.2%, P < 0.05). RV/LV+S ratio was higher in bleomycin-alone mice with improvement in ratio when sildenafil was administered (33.00 ± 0.01% vs. 20.98 ± 0.01% P < 0.05). Histology showed less pulmonary vascular and RV fibrosis in the group cotreated with sildenafil. Bleomycin was associated with a marked increase in superoxide generation by DHE histological staining and luminol activity in both heart and lung. Treatment with sildenafil resulted in a concomitant reduction in superoxide levels in both heart and lung. These data demonstrate that PDE5 inhibition ameliorates RV hypertrophy and pulmonary fibrosis associated with intratracheal bleomycin in a manner that is associated with improved NOS coupling and a reduction in reactive oxygen species signaling.

Although chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) have distinct clinical features, both diseases may coexist in a patient because they share similar risk factors such as smoking, male sex, and old age. Patients with both emphysema in upper lung fields and diffuse ILD are diagnosed with combined pulmonary fibrosis and emphysema (CPFE), which causes substantial clinical deterioration. Patients with CPFE have higher mortality compared with patients who have COPD alone, but results have been inconclusive compared with patients who have idiopathic pulmonary fibrosis (IPF). Poor prognostic factors for CPFE include exacerbation, lung cancer, and pulmonary hypertension. The presence of interstitial lung abnormalities, which may be an early or mild form of ILD, is notable among patients with COPD, and is associated with poor prognosis. Various theories have been proposed regarding the pathophysiology of CPFE. Biomarker analyses have implied that this pathophysiology may be more closely associated with IPF development, rather than COPD or emphysema. Patients with CPFE should be advised to quit smoking and undergo routine lung function tests, and pulmonary rehabilitation may be helpful. Various pharmacologic agents may be beneficial in patients with CPFE, but further studies are needed.
