|Living with PF
Pulmonary (lung) fibrosis, is a scarring of the lungs, and is the consequence of untreated pulmonary inflammation (alveolitis). It is often also referred to as interstitial lung disease.
Pulmonary fibrosis (PF) can occur by itself or as secondary to some autoimmune diseases, including systemic sclerosis (SSc, scleroderma).
What is pulmonary fibrosis? Pulmonary fibrosis is scarring throughout the lungs. Pulmonary fibrosis can be caused by many conditions such as sarcoidosis, hypersensitivity pneumonitis, asbestosis, certain medications, etc. MedicineNet
About 70% of patients with diffuse scleroderma develop some degree of pulmonary fibrosis, which is the most common cause of death directly related to scleroderma. Therefore, prompt diagnosis and aggressive treatment of pulmonary fibrosis is very important.
Esophageal dilatation and interstitial lung disease in systemic sclerosis (SSc): A cross-sectional study. Increasing esophageal diameter on high–resolution computed tomography in patients with SSc is associated with more severe radiographic interstitial lung disease, lower lung volumes, and lower DLCO % predicted.

Clinical characteristics and survival in idiopathic pulmonary fibrosis (IPF) and connective tissue disease-associated usual interstitial pneumonia (CTD-UIP). Although the survival of CTD-UIP patients was similar compared with that of IPF/UIP patients, it appears that Undifferentiated Connective Tissue Disease influences the survival rate of CTD-UIP patients.

Good outcome of interstitial lung disease in patients with scleroderma associated to anti-PM/Scl antibody. Several features and prognosis of ILD in SSc may be modified depending on the identified immunological profile. Seminars in Arthritis and Rheumatism, 07/15/2014. (Also see Antibodies in Systemic Scleroderma)
Symptoms of pulmonary fibrosis include shortness of breath (dyspnea) on exertion. In treating scleroderma, its best to identify pulmonary fibrosis before it is so advanced that it shows up on x-ray. That is why your doctor may order an echocardiogram, or other tests. ISN.
Pulmonary Fibrosis Correlations and Complications. Pulmonary fibrosis can be correlated or complicated with the following conditions, such as esophageal issues, cancer, connective tissue diseases, heart problems, infections, pulmonary hypertension and thyroid diseases. ISN.

Living with Pulmonary Fibrosis requires a constant awareness of your symptoms, your breathing, your surroundings, and your overall well-being. Work closely with your doctors on treatments, diet and exercise. If you require oxygen therapy, use it. It protects your heart as well as improves the quality of your life. ISN.
Dangers of Oxygen
Treatments for Pulmonary Fibrosis include oxygen therapy, oral and IV cyclophosphamide, biologic agents, Mycophenolate Mofetil (cellcept), and lung transplants. There are current clinical trials that are studying the effectiveness of various treatments for scleroderma. Some of these trials are using the treatment's effect on the patient's pulmonary fibrosis as a measurement criterion. ISN.

Th–17 cytokines and interstitial lung involvement in systemic sclerosis (SSc). In diffuse SSc patients our results show a clear link between Th–17 cytokines measured both in exhaled breath condensate and in serum with interstitial lung involvement.

Netrin–1 Regulates Fibrocyte Accumulation in the Decellularized Fibrotic Sclerodermatous Lung Microenvironment and in Bleomycin–Induced Pulmonary Fibrosis. Netrin–1 regulates bleomycin–induced pulmonary fibrosis in mice and it might be a novel therapeutic target in scleroderma–related interstitial lung disease. PubMed, Arthritis Rheumatol, 2016 May;68(5):1251-61.
Frequency of circulating topoisomerase–I–specific CD4 T cells predicts presence and progression of interstitial lung disease (ILD) in scleroderma. Topo–I–specific T cells can be reliably quantified in the peripheral blood of patients with scleroderma, exhibit a pro–inflammatory Th17 phenotype, and predict progression of ILD. BioMed Central, Arthritis Research & Therapy, 05/04/2016. (Also see Causes of Scleroderma: B Cells and T Cells)
M10, a caspase cleavage product of the hepatocyte growth factor receptor, interacts with Smad2 and demonstrates antifibrotic properties in vitro and in vivo. M10 peptide interacts with Smad2 and demonstrates strong antifibrotic effects in vitro and in vivo in an animal model of lung fibrosis and should be considered as a potential therapeutic agent for systemic sclerosis and other fibrosing diseases. PubMed, Transl Res, 2016 Apr;170:99-111. (Also see Skin Fibrosis)
Research of Lung Fibrosis in Scleroderma (SSc) Reveals High Levels of Antibodies That Correlate with Disease Progression. Circulating antibodies against specific chemokine receptors exist in higher levels in patients with SSc and these antibodies correlate with disease progression and clinical manifestations of the disease. Scleroderma News, 02/25/2016.
Scleroderma–related Interstitial Lung Disease (SSc–ILD) Not Linked to Idiopathic Interstitial Pneumonia. The study confirmed that SSc–ILD and idiopathic interstitial pneumonia are different diseases, not sharing a genetic basis. Scleroderma News, 02/02/2016. (Also see Lung Involvement)
Fewer Mycophenolate Adverse Events in Scleroderma Lung Study. Mycophenolate mofetil can be substituted for cyclophosphamide for the immunosuppressive treatment of scleroderma-related interstitial lung disease and might even be safer. Medscape, 11/02/2015.

Pleural irregularity (PI), a new ultrasound sign for the study of interstitial lung disease(ILD) in systemic sclerosis (SSC) and antisynthetase syndrome (ASS). PI is useful for evaluation of ILD in SSc and ASS patients and can be incorporated into a diagnostic algorithm in SSc patients to reducing the need for exposure to ionising radiation.
