A patient with cryptogenic fibrosing alveolitis, with both mural and desquamative features, had two lung biopsies at the times of coronary artery surgery. These lung specimens were studied, using light and electron microscopy, with immunofluorescence techniques and electron microanalysis. In addition to the typical changes of cryptogenic fibrosing alveolitis previously reported, we found blue-staining bodies within alveolar macrophages and giant cells. These bodies were 15--25 micrometer in diameter with an iron rich outer rim and core of connective tissue mucin--possibly chondroitin sulphate or dermatan sulphate. It seems unlikely that these blue bodies were due to fibreglass dust to which the patients had had a trivial exposure, but their exact nature and significance remains unclear.. ...

SUMMARY. Twenty patients with unexplained pulmonary fibrosis and circulating antinuclear factor were identified. Diseases commonly associated with antinuclear factor, such as systemic lupus erythematosus or scleroderma, were excluded. Half of the patients showed typical restrictive ventilatory defects and X-ray evidence of severe fibrotic changes. The remaining patients predominantly had evidence of obstructive airway diseases.. Four lung biopsies were available. Three showed histological evidence of interstitial pulmonary fibrosis. Immunofluorescent study of one of the biopsy sections with pulmonary fibrosis from a patient with only IgM serum antinuclear factor showed IgM in the alveolar septa. Relatively little fibrosis was present in immunoglobulin-laden areas whereas no immunoglobulin could be demonstrated in the adjacent alveolar septa showing marked fibrosis. Seven out of 10 patients with X-ray evidence of severe interstitial pulmonary fibrosis and typical restrictive ventilatory defects ...

TY - JOUR. T1 - Abatement of bleomycin-induced increases in vascular permeability, inflammatory cell infiltration, and fibrotic lesions in hamster lungs by combined treatment with taurine and niacin. AU - Wang, Q.. AU - Hyde, D. M.. AU - Giri, S. N.. PY - 1992. Y1 - 1992. N2 - BACKGROUND: The bleomycin (BL) hamster model of interstitial pulmonary fibrosis has been widely used to study the pathogenesis of interstitial pulmonary fibrosis and to screen potentially desirable antifibrotic agents. We have recently shown that taurine and niacin in combination, diminished BL- induced increases in lung lipid peroxidation and hydroxyproline content in hamsters. In the present study, we have evaluated the effects of taurine and niacin on the bronchoalveolar lavage (BAL) cells, and morphologic and morphometric features of the lung in the same model of pulmonary fibrosis. EXPERIMENTAL DESIGN: The hamsters were divided into 4 groups: saline; taurine + niacin + saline; BL; and taurine + niacin + BL. Treatment ...
The mechanisms underlying the pathogenesis of idiopathic pulmonary fibrosis (IPF) involve multiple pathways, such as inflammation, epithelial mesenchymal transition, coagulation, oxidative stress, and developmental processes. The small GTPase, RhoA, and its target protein, Rho-kinase (ROCK), may interact with other signaling pathways known to contribute to pulmonary fibrosis. This study aimed to determine the beneficial effects and mechanisms of fasudil, a selective ROCK inhibitor, on bleomycin-induced pulmonary fibrosis in mice. Our results showed that the Aschcroft score and hydroxyproline content of the bleomycin-treated mouse lung decreased in response to fasudil treatment. The number of infiltrated inflammatory cells in the bronchoalveolar lavage fluid (BALF) was attenuated by fasudil. In addition, fasudil reduced the production of transforming growth factor-β1 (TGF-β1), connective tissue growth factor (CTGF), alpha-smooth muscle actin (α-SMA), and plasminogen activator inhibitor-1 (PAI-1)

The mortality analysis of the members of the BTS CFA cohort identified that there were 46 deaths from lung cancer among 488 people who died (9.4%) and 23 (6.9%) deaths with both idiopathic fibrosing alveolitis and lung cancer mentioned on the death certificates, a figure only marginally higher than the UK co-mortality estimate (5.6%).3. It is plausible that the population-based co-mortality studies2 3 were limited by incomplete listings of pulmonary fibrosis on the death certificates, and diagnostic misclassification may have also contributed to the lack of association between IPF and lung cancer. A far higher prevalence of lung cancer was reported in other studies. The highest were those by Matsushita et al,1 Hironaka and Fukayama6 and Qunn,7 with a lung cancer prevalence of 48.2%, 45.7% and 43.1%, respectively. All of these studies were autopsy studies conducted in Japan and none was blinded. These estimates may be elevated by the increased probability of the presence of lung cancer being ...
TY - JOUR. T1 - A new model of progressive pulmonary fibrosis in rats. AU - Last, Jerold A. AU - Gelzleichter, T. R.. AU - Pinkerton, Kent E. AU - Walker, R. M.. AU - Witschi, H.. PY - 1993. Y1 - 1993. N2 - Sprague-Dawley rats were exposed for 6 h daily to 0.8 ppm of ozone and 14.4 ppm of nitrogen dioxide. Approximately 7 to 10 wk after the initiation of exposure, animals began to demonstrate respiratory insufficiency and severe weight loss. About half of the rats died between Days 55 and 78 of exposure; no overt ill effects were observed in animals exposed to filtered air, to ozone alone, or to nitrogen dioxide. Biochemical findings in animals exposed to ozone and nitrogen dioxide included increased lung content of DNA, protein, collagen, and elastin, which was about 300% higher than the control values. The collagen-specific crosslink hydroxypyridinium, a biomarker for mature collagen in the lung, was decreased by about 40%. These results are consistent with extensive breakdown and remodeling ...

Circulating fibrocytes had been reported to migrate into the injured lungs, and contribute to fibrogenesis via chemokine-chemokine receptor systems including CXCL12-CXCR4 axis. Here we hypothesized that blockade of CXCR4 might inhibit the migration of fibrocytes to the injured lungs and the subsequent pulmonary fibrosis. To explore the antifibrotic effects of blockade of CXCR4, we used a specific antagonist for CXCR4, AMD3100, in bleomycin-induced pulmonary fibrosis model in mice. Administration of AMD3100 significantly improved the loss of body weight of mice treated with bleomycin, and inhibited the fibrotic lesion in subpleural areas of the lungs. The quantitative analysis demonstrated that treatment with AMD3100 reduced the collagen content and fibrotic score (Aschcroft score) in the lungs. Although AMD3100 did not affect cell classification in bronchoalveolar lavage fluid on day 7, the percentage of lymphocytes was reduced by AMD3100 on day 14. AMD3100 directly inhibited the migration of ...
Chronic lung diseases including asthma and idiopathic pulmonary fibrosis (IPF) are characterized by the airway inflammation, airway remodeling, subepithelial fibrosis, and hypoxia. Previous study indicated that hypoxia plays a critical role in tissue fibrosis. In chronic asthma and IPF, the CXCR4/CXCL12 (stromal cell-derived factor-1, SDF-1) axis plays important role in pulmonary fibrosis. CXCL12 is a potent chemokine for homing of CXCR4+ fibrocytes to sites of lung tissue injury, which directly contribute to pulmonary fibrosis. Circulating CXCR4+ fibrocytes and CXC12 were found to be significantly increases in both plasma and lung of the patient with pulmonary fibrosis. Moreover, an anti-CXCL12 neutralizing antibody attenuated bleomycin-induced pulmonary fibrosis in mice. In addition, CXCL12 plays an important role in carcinoma-associated fibroblast differentiation. These results suggest that interfering with CXCL12 network may help to block pulmonary fibrosis. There is increasing evidence ...

The specific role of Toll-like receptor 4 (TLR4) in bleomycin-induced lung fibrosis of mice, a model of human idiopathic pulmonary fibrosis, has not been characterized. We injected bleomycin intratracheally into TLR4 knockout (TLR4-/-) and wild-type (WT) mice. Twenty-one days after injection, mice were sacrificed and their lungs were harvested for pathological, hydroxyproline, mRNA expression, and collagen I analyses. Body weight changes and mortality were observed.

Pulmonary fibrosis may be a secondary effect of other diseases. Most of these are classified as interstitial lung diseases. Examples include autoimmune disorders, viral infections and bacterial infection like tuberculosis which may cause fibrotic changes in both lungs upper or lower lobes and other microscopic injuries to the lung. However, pulmonary fibrosis can also appear without any known cause. In this case, it is termed idiopathic. Most idiopathic cases are diagnosed as idiopathic pulmonary fibrosis. This is a diagnosis of exclusion of a characteristic set of histologic/pathologic features known as usual interstitial pneumonia (UIP). In either case, there is a growing body of evidence which points to a genetic predisposition in a subset of patients. For example, a mutation in surfactant protein C (SP-C) has been found to exist in some families with a history of pulmonary fibrosis. Autosomal dominant mutations in the TERC or TERT genes, which encode telomerase, have been identified in ...

Here, we show the pivotal role of PDGF signaling in the pathogenesis of radiation-induced pulmonary fibrosis. Importantly, our findings suggest that direct inhibition of fibrogenesis by PDGF RTKIs is an effective strategy to attenuate lung fibrosis. We found that three distinct inhibitors of PDGF signaling (Imatinib/Gleevec, SU9518, and SU11657) markedly attenuated pulmonary fibrosis in a mouse model of radiation-induced lung fibrosis (C57/Bl6).. We could demonstrate that treatment of irradiated mice with PDGF RTKIs markedly attenuates the development of fibroblast foci, the hallmark of pulmonary fibrosis, and the subsequent remodeling of the lung architecture. The morphological results were in agreement with qualitative and quantitative high resolution CT scans of mouse lungs, demonstrating that PDGFR inhibition could dramatically attenuate the typical radiological features of lung fibrosis induced by thoracic irradiation.. Interestingly, with respect to the time course of fibrosis development, ...

Feifukang (FFK) is a traditional Chinese medicine composed of herbs that protect lung function. However, difficulty arises regarding the clinical application of FFK due to the complex mechanism of Chinese medicines. This study aimed to investigate the efficacy of FFK and explore its targeted genes and pathways. Histopathological changes and collagen deposition were measured to evaluate the effect of FFK on bleomycin-induced pulmonary fibrosis in mice. The differentially expressed targeted genes and pathways were first screened using RNA sequencing. Then network pharmacology and other experiments were conducted to confirm RNA sequencing data. FFK treatment reduced the pathological score and collagen deposition, with a decrease in α-SMA and collagen. RNA sequencing and network pharmacology results all showed that FFK can ameliorate pulmonary fibrosis through multi-genes and multi-pathways. The targeted genes in JAK-STAT signaling pathway are some of the most notable components of these multi-genes and

Ludhiana, 6th April, 2012 (Shalu Arora and Rector Kathuria) Mrs Amrit Kaur-a 65 year old lady - W/o S. Gurcharan Singh of Janakpuri was in a serious condition. She had developed a large clot in her left leg which was in imminent danger of getting loose and blocking her lungs. She was seen in the Emergency by Dr Harinder Singh Bedi - head of Cardio Vascular Endovascular & Thoracic Surgery at the Christian Medical College & Hospital in Ludhiana. On examination and investigation Dr Bedi found that she already had previous episodes of pulmonary embolism. As it is - she suffered from a lung disease called Interstitial Pulmonary Fibrosis for which she was already under treatment. Her lung functions were very low because of the ILD and any further pulmonary embolism would have been potentially fatal. After a thorough check up she underwent a new procedure called catheter directed thrombolysis (CDT) with a strong blood thinner - tissue plasminogen activator (TPA) . Dr Bedi explained that this clot ...

Idiopathic pulmonary fibrosis is an inexorably fatal disorder characterized by connective tissue deposition within the terminal air spaces resulting in loss of lung function and eventual respiratory failure. Previously, we demonstrated that foci of activated fibroblasts expressing high levels of fibronectin, procollagen, and smooth muscle actin and thus resembling those found in healing wounds are responsible for the connective tissue deposition and scarring in idiopathic pulmonary fibrosis. Using in situ hybridization and immunohistochemistry, we now demonstrate the presence of transforming growth factor beta 1 (TGF-beta 1), a potent profibrotic cytokine, in the foci containing these activated fibroblasts. These results suggest that matrix-associated TGF-beta 1 may serve as a stimulus for the persistent expression of connective tissue genes. One potential source of the TGF-beta 1 is the alveolar macrophage, and we demonstrate the expression of abundant TGF-beta 1 mRNA in alveolar macrophages in ...

Pulmonary fibrosis is more prevalent among men than it is among women. Adults between the ages of 40 and 70 have the highest risk, and approximately 65% of those affected by the condition are over the age of 60. Certain chemotherapy drugs and cardiac medications are potential risk factors, and these drugs are most commonly used by individuals in this age category. Some medical researchers believe that pulmonary fibrosis may begin as an inflammatory response. In tissues like the lungs that dont have the capacity to regenerate, inflammation can lead to scarring. Scar tissue cant support specialized cells, so functional impairment occurs. This theory appears to be supported by the fact that pulmonary fibrosis often arises in conjunction with autoimmune diseases like lupus erythematosus, rheumatoid arthritis, and scleroderma. There are also higher incidences of pulmonary fibrosis among individuals whove been exposed to environmental toxicants like cigarette smoke, asbestos fibers, radiation, and ...
Interleukin-8 (IL-8) is a potent chemo-attractant cytokine responsible for neutrophil infiltration in lungs with idiopathic pulmonary fibrosis (IPF). The IL-8 protein and mRNA expression are increased in the lung with IPF. We evaluated the effect of single nucleotide polymorphisms (SNPs) of the IL-8 gene on the risk of IPF. One promoter (rs4073T>A) and two intronic SNPs (rs2227307T>G and rs2227306C>T) of the IL-8 genes were genotyped in 237 subjects with IPF and 456 normal controls. Logistic regression analysis was applied to evaluate the association of these SNPs with IPF. IL-8 in BAL fluids was measured using a quantitative sandwich enzyme immunoassay, and promoter activity was assessed using the luciferase reporter assay. The minor allele frequencies of rs4073T>A and rs2227307T>G were significantly lower in the 162 subjects with surgical biopsy-proven IPF and 75 subjects with clinical IPF compared with normal controls in the recessive model (OR = 0.46 and 0.48, p = 0.006 and 0.007, respectively).

Our studies demonstrate that signaling via the CCR2 receptor leads to the generation of pro-fibrotic signals following FITC or bleomycin inoculation. In particular, our studies yield several important points: 1) in the absence of CCR2, FITC-induced pulmonary fibrosis is diminished both histologically and quantitatively; 2) the protection is related to the absence of this specific chemokine receptor; deletion of the CCR5 receptor had no effect on the severity of pulmonary fibrosis; 3) the protection conferred by the absence of CCR2 is a generalized phenomenon; CCR2−/− mice are protected from pulmonary fibrosis induced by either FITC or bleomycin; 4) the protection from pulmonary fibrosis seen in CCR2−/− mice is not due to differences in early lung injury caused by the FITC inoculation; 5) despite the absence of the CCR2 receptor, CCR2−/− mice develop an inflammatory cellular response following FITC inoculation that is similar in magnitude and composition compared with the response in ...

December 26, 2017. To date, the molecular basis of pulmonary fibrosis has been poorly understood. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now shown that reduced activity of the transcription factor FoxO3 plays a key role in the development of the disease. In research on mice, the progress of the disease was able to be halted using drugs that boost FoxO3 activity. The researchers are hoping they may have found a possible approach to treatment.. Idiopathic pulmonary fibrosis is currently an incurable lung disease, in which sufferers lose the ability to absorb adequate oxygen. Although the word idiopathic means that the cause is unknown, the disease primarily affects former and active heavy smokers from the age of 50.. An important role in idiopathic pulmonary fibrosis is played by connective tissue cells called fibroblasts. These cells provide structure to the air sacs (alveoli) in the lungs. During development of the disease, characteristic ...
Background Weve previously explored a therapeutic strategy for specifically targeting the profibrotic activity of IL-13 during experimental pulmonary fibrosis using a fusion protein comprised of human IL-13 and a mutated form of exotoxin A (IL13-PE) and observed that the intranasal delivery of IL13-PE reduced bleomycin-induced pulmonary fibrosis through its elimination of IL-13-responsive cells in the lung. of whole lung samples were performed at day 28 after bleomycin. Intrapulmonary infection promoted a neutralizing IgG2A and IgA antibody response in BALF and serum. Surprisingly, histological analysis showed a prior disease attenuated the introduction of bleomycin-induced pulmonary fibrosis, that was further attenuated from the intranasal administration of IL13-PE modestly. Although prior intranasal administration CGI1746 of IL13-PE didnt elicit an antibody response, the systemic administration of IL13-PE induced a solid neutralizing antibody response. Nevertheless, the last systemic ...

Several cases of fatal exacerbations of fibrosing alveolitis associated with rheumatoid arthritis after infliximab treatment have recently been reported.1 We report here a case of fatal exacerbation of pulmonary fibrosis after adalimumab treatment in a patient with polyarthritis related to systemic sclerosis (SSc).. The patient, a 74 year old woman, had been diagnosed 5 years previously with severe Raynauds syndrome, sclerodactyly, pulmonary fibrosis, abnormal oesophageal peristalsis, and non-specific antinuclear antibodies (1/100; indirect immunofluorescence on Hep 2 cells). She also had severe distal polyarthritis affecting the wrists, metacarpophalangeal and proximal interphalangeal joints, with demineralisation but no erosion on x ray examination. She tested negative for rheumatoid factor and anti-cyclic citrullinated peptide antibodies. Successive treatments with low dose prednisone associated with methotrexate, leflunomide or azathioprine were ineffective ...
The study is a major step toward understanding and one day treating pulmonary fibrosis, which affects about 100,000 people in the U.S. The disease often is called idiopathic pulmonary fibrosis because, in most cases, the cause cannot be found. While the prognosis is unpredictable, patients typically survive only three to five years after diagnosis, according to the U.S. National Library of Medicine.. Pulmonary fibrosis slowly robs patients of breath and finally life, said Paul W. Noble, MD, professor and chair of the Department of Medicine and director of the Womens Guild Lung Institute at Cedars-Sinai. In our study, we identified novel potential pathways to finding treatments for this relentless disease. Noble was the studys principal investigator.. The investigators focused on alveoli, the small air sacs at the ends of lung airways. In the alveoli, oxygen and carbon dioxide are exchanged with blood during respiration. Epithelial cells that line the alveoli also make a substance that ...
Mesenchymal stromal/stem cell (MSC) therapy has shown promise in experimental models of idiopathic pulmonary fibrosis (IPF). The aim of this study was to test the therapeutic effects of extracellular vesicles produced by human BM MSCs (MEx) in a bleomycin-induced pulmonary fibrosis model and investigate mechanisms of action. Adult C57BL/6 mice were challenged with endotracheal instillation of bleomycin and treated with MEx concurrently, or for reversal models, at day 7 or 21. Experimental groups were assessed at day 7, 14, or 28. Bleomycin-challenged mice presented with severe septal thickening and prominent fibrosis, and this was effectively prevented or reversed by MEx treatment. MEx modulated lung macrophage phenotypes, shifting the proportions of lung proinflammatory/classical and nonclassical monocytes and alveolar macrophages toward the monocyte/macrophage profiles of control mice. A parallel immunomodulatory effect was demonstrated in the BM. Notably, transplantation of MEx-preconditioned ...
Pulmonary fibrosis (scarring throughout the lungs) symptoms are shortness of breath, coughing, and diminished exercise tolerance. Idiopathic pulmonary fibrosis describes a condition in which the cause is unknown. Pulmonary fibrosis has many causes such as exposure to asbestos, infections, lupus, RA, and medication.
In the present study, TGF-β1 was used to induce the proliferation of lung fibroblasts and generate an in vitro model of pulmonary fibrosis. In a preliminary experiment, treatment with 50 ng/ml TGF-β1 for 48 h induced the proliferation of lung fibroblasts, indicating that this was a suitable concentration to establish the in vitro model. This model has also been used in foreign and domestic studies (31-33). In addition, as lung fibroblasts are considered to participate in pulmonary inflammation and fibrosis in numerous autoimmune diseases, including rheumatoid arthritis (4,34), the model has also been used to investigate pulmonary fibrosis secondary to numerous other diseases in vitro. The present study suggested that TGF-β1 also induced lung fibroblasts to secrete inflammatory cytokine IL-6 and synthesize ColIα and ColIII, which are among the deposited ECM materials (35). It is likely that in lung tissue affected by pulmonary fibrosis, fibroblasts were affected by inflammation for a long ...

Idiopathic pulmonary fibrosis is a chronic, progressive lung disease. This condition causes scar tissue (fibrosis) to build up in the lungs, which makes the lungs unable to transport oxygen into the bloodstream effectively. The disease usually affects people between the ages of 50 and 70. Idiopathic pulmonary fibrosis belongs to a group of conditions called interstitial lung diseases (also known as ILD), which describes lung diseases that involve inflammation or scarring in the lung.. The most common signs and symptoms of idiopathic pulmonary fibrosis are shortness of breath and a persistent dry, hacking cough. Many affected individuals also experience a loss of appetite and gradual weight loss. Some people with idiopathic pulmonary fibrosis develop widened and rounded tips of the fingers and toes (clubbing) resulting from a shortage of oxygen. These features are relatively nonspecific; not everyone with these health problems has idiopathic pulmonary fibrosis. Other respiratory diseases, some of ...

Bleomycin-induced lung fibrosis in mice reproduces some key features of pulmonary fibrosis in humans including alveolar inflammation, myofibroblast proliferation, and collagen deposition. Glucocorticoids have been used as first-line therapy for the treatment of lung fibrosis, although their clinical efficacy is equivocal. We examined the effect of the glucocorticoid, methylprednisolone (MP), and the estrogen metabolite, 2-methoxyestradiol (2MEO) on bleomycin-induced bronchoalveolar inflammation, fibrosis, and changes in lung function. The characterization of the time-course of the bleomycin-induced fibrosis indicated that lung dry mass and hydroxyproline content showed less variance than histopathological assessment of fibrosis. The bleomycin-induced increases in bronchoalveolar lavage (BAL) fluid cell number and protein levels were not significantly influenced by treatment with either MP (1 mg.(kg body mass)(-1).day(-1), i.p.) or 2MEO (50 mg.(kg body mass)(-1).day(-1), i.p.). Lung fibrosis, ...
We evaluated 500 consecutive cases, 426 of which were included: 266 had TBLC and 160 had SLB. 189 patients had idiopathic pulmonary fibrosis, 143 had other fibrotic interstitial lung diseases, and 94 had non-fibrotic interstitial lung diseases. Patients undergoing TBLC had more comorbidities and better preserved lung function compared with those undergoing SLB; among patients with a final MDT diagnosis of idiopathic pulmonary fibrosis, patients undergoing TBLC were older, had more comorbidities, and had a different post-biopsy treatment profile than those who received SLB. The distinction between idiopathic pulmonary fibrosis and other interstitial lung diseases made by MDT diagnosis on the basis of TBLC biopsy had clear prognostic significance, with a 5-year transplant-free survival of 68% (95% CI 57-76) in patients with an MDT idiopathic pulmonary fibrosis diagnosis based on TBLC compared with 93% (87-96) in patients without an idiopathic pulmonary fibrosis diagnosis based on TBLC (hazard ...

Latest industry research report on: Global Idiopathic Pulmonary Fibrosis Therapeutic Market , Industry Size, Share, Research, Reviews, Analysis, Strategies, Demand, Growth, Segmentation, Parameters, Forecasts. A rare lung disease often terminal, idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease affecting the lung interstitium. Patients diagnosed with IPF suffer an extreme lung deterioration resulting a decline in the lung functioning. IPF causes pulmonary fibrosis, which basically means damaging of the lung tissues. Breathing distress is the most common intricacy involved with idiopathic pulmonary fibrosis.. The cause of idiopathic pulmonary fibrosis still remains unknown, however, it is mostly linked with excessive inhalation of smoke or dust, exposure to unhealthy gases and chemicals and smoking of cigarettes. IPF may also be caused due to genetic predisposition or develop from other lung condition.. Some of the medical conditions, which may develop in a patient with ...

Previously, we have shown that heparan sulfate (HS) 6-O-endosulfatase 1 (Sulf1) is a transforming growth factor-β1 (TGF-β1)-responsive gene in normal human lung fibroblasts and functions as a negative feedback regulator of TGF-β1 and that TGF-β1 induces the expression of Sulf1 as well as that of the closely related Sulf2 in a murine model of pulmonary fibrosis. In this study, we focused on the role of Sulf2 in modulating TGF-β1 function and the development of pulmonary fibrosis. We found that Sulf2 mRNA was overexpressed in lung samples from human patients with idiopathic pulmonary fibrosis (IPF), and Sulf2 protein was specifically localized to the hyperplastic type II alveolar epithelial cells (AECs). In vitro, TGF-β1 induced the expression of Sulf2 with accompanied HS 6-O-desulfation in A549 cells, adenocarcinoma cells derived from the type II alveolar epithelium. Using small interference RNA to block Sulf2 expression, we observed a biphasic TGF-β1 response with early enhanced Smad ...
Common intrinsic or interstitial lung diseases include interstitial pulmonary fibrosis, sarcoidosis, and hypersensitivity pneumonitis. The autoimmune (collagen) diseases can affect any joint in the body, including the costochondral and costovertebral joints. Restrictive lung diseases are much less common than asthma; thus, it is not surprising that there are not enough hard data to assess whether such processes increase a divers risk of pulmonary barotrauma. If your lungs cant hold as much air as they used to, you may have a restrictive lung disease. In severe cases, the lung tissue, heart and major vessels may be compromised by the deformity and altered mechanics. The AP and transverse diameters of the chest should increase with inspiration, but do not increase to normal levels in these conditions. Symptoms consist of non-productive cough, wheezing and dyspnea; chest radiography is normal in most cases. This can occur when tissue in the chest wall becomes stiffened, or due to weakened muscles ...

Objectives Reduced caveolin-1 levels in lung fibroblasts from patients with scleroderma and the lungs of bleomycin-treated mice promote collagen overexpression and lung fibrosis. This study was undertaken to determine whether caveolin-1 is deficient in leucocytes from bleomycin-treated mice and patients with scleroderma and to examine the consequences of this deficiency and its reversal.. Methods Mice or cells received the caveolin-1 scaffolding domain (CSD) peptide to reverse the pathological effects of reduced caveolin-1 expression. In bleomycin-treated mice, the levels of caveolin-1 in leucocytes and the effect of CSD peptide on leucocyte accumulation in lung tissue were examined. To validate the results in human disease and to identify caveolin-1-regulated molecular mechanisms, monocytes and neutrophils were isolated from patients with scleroderma and control subjects and caveolin-1, extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), p38, CXC chemokine ...
Idiopathic Pulmonary Fibrosis is a respiratory disease characterized by the formation of scar tissue in the lungs called fibrosis. IPF patients exhibit a rapid increase in fibrosis leading to severe breathing difficulties, a persistent cough, and difficulty in performing daily tasks. It usually affects people between 50 and 70 years old, particularly men and smokers. The disease is fatal and approximately two-thirds of patients succumb within five years of diagnosis. Most IPF patients die of lung failure while waiting for a lung donor.. IPF is estimated to affect over 130,000 Americans. Every year, 48,000 new cases are diagnosed and 40,000 patients die from the disease. Although there are two FDA-approved therapies for IPF, Esbriet (Roche) and OFEV (Boehringer-Ingelheim), there is no cure.. AEOL 10150 in Idiopathic Pulmonary Fibrosis. Data generated in pre-clinical studies performed under the BARDA contract for Lung-ARS suggest that 10150 may prevent the development of fibrosis in diseases such ...
Idiopathic Pulmonary Fibrosis (IPF) is a rare, chronic, progressive fibrosing interstitial pneumonia which is found to affect the middle-aged and older adults; and affects lung tissue (alveoli in particular) by either thickening, stiffening, or persistent and progressive scarring (fibrosis) which increases irreversibly over time. If an individual has IPF, scarring affects the air sacs, limiting the amount of oxygen that gets into the blood. With less oxygen in the blood, one can get breathlessness from everyday activities, like walking. This group of lung disorders is also known as Diffuse Parenchymal Lung Diseases, which is characterized by a broader umbrella of Interstitial Lung Diseases (IDLs).. According to DelveInsight, the total Idiopathic Pulmonary Fibrosis (IPF) prevalent cases in 7 MM was found to be 229,170, in the year 2017..

Pirfenidone in the treatment of idiopathic pulmonary fibrosis: an evidence-based review of its place in therapy George A Margaritopoulos,1 Eirini Vasarmidi,2 Katerina M Antoniou2 1Interstitial Lung Disease Unit, Royal Brompton Hospital, London, UK; 2Department of Thoracic Medicine and Laboratory of Molecular and Cellular Pneumonology, Interstitial Lung Disease Unit, University Hospital of Heraklion, Heraklion, Greece Abstract: The landscape of idiopathic pulmonary fibrosis (IPF) has changed. The significant progress regarding our knowledge on the pathogenesis of the disease together with the experience achieved after a series of negative trials has led to the development of two drugs for the treatment of IPF. Both pirfenidone and nintedanib can slow significantly the rate of disease progression. They are safe with side effects that can be either prevented by close collaboration between health care professionals and patients or treated successfully when they occur, rarely leading to treatment
TY - JOUR. T1 - Mechanisms of neutrophil accumulation in the lungs of patients with idiopathic pulmonary fibrosis. AU - Hunninghake, G. W.. AU - Gadek, J. E.. AU - Lawley, T. J.. AU - Crystal, R. G.. PY - 1981/1/1. Y1 - 1981/1/1. N2 - Neutrophils are a characteristic feature of the alveolitis of idiopathic pulmonary fibrosis (IPF), a chronic disorder limited to lung. One mechanism by which neutrophils may be selectively attracted to lung and not other tissues is via the secretion of a neutrophil-specific chemotactic factor by alveolar macrophages. To evaluate the role of alveolar macrophages in modulating the migration of neutrophils to the lung in IPF, alveolar macrophages, obtained by bronchoalveolar lavage of patients with IPF, were evaluated for their ability to release a chemotactic factor for neutrophils. Unstimulated alveolar macrophages from normal individuals did not release the factor. In patients with IPF, there was a significant correlation between the proportions of neutrophils in ...
Idiopathic pulmonary fibrosis biomarkers: clinical utility and a way of understanding disease pathogenesis Matthew Flynn, Elisabeth S Baker, Daniel J Kass Dorothy P and Richard P Simmons Center for Interstitial Lung Disease, Division of Pulmonary, Allergy, and Critical Care Medicine, University of Pittsburgh, Pittsburgh, PA, USA Abstract: Idiopathic pulmonary fibrosis (IPF) is a typically fatal disease that remains incompletely understood despite intense study and the arrival of drugs that may alter the natural history of the disease. Rendering an accurate diagnosis and predicting prognosis remain challenging problems to clinicians. One potential solution to these clinical problems is the identification of IPF biomarkers, easily measured factors that can be employed to predict clinical behavior. Candidate biomarkers have been identified by research in the laboratory on potential culprit cells or genes that may contribute to the pathogenesis of IPF. In this review, we present the current data on a
Idiopathic pulmonary fibrosis (IPF), the prototype of interstitial lung diseases, has the worst prognosis and is the only interstitial lung disease for which approved pharmacological treatments are available. Despite being considered a rare disease, IPF patients pose major challenges to both physicians and healthcare systems. It is estimated that a large number of IPF patients reside in BRIC countries (Brazil, Russia, India, and China) given their overall total population of approximately 3 billion inhabitants. Nevertheless, the limited availability of chest imaging in BRIC countries is considered a chief obstacle to diagnosis, since high-resolution computed tomography of the chest is the key diagnostic test for IPF. Further, obtaining reliable lung function tests and providing treatment access is difficult in the more rural areas of these countries. However, IPF might represent an opportunity for BRIC countries: the exponentially increasing demand for the enrollment of IPF patients in clinical ...

Idiopathic pulmonary fibrosis (IPF) is a chronic fibrosing interstitial lung disease with a poor prognosis. The impact of malnutrition, especialy fat-free mass (FFM), on mortality is scarcely assessed in IPF patients. This study aimed at identifying factors associated with higher mortaliy in IPF. Nutritional status of 185 consecutive IPF patients from a referal Centre were prospectively evaluated by bioelectrical impedancemeter analysis (BIA) to measure FFM, body mass index (BMI), mid-arm circumference, triceps skinfold thickness, food intake analogue visual scale and biology. Malnutrition was defined as a FFM index (FFMI) |15 in women and |17 in men. Stepwise logistic regressions were performed to identify the factors associated with mortality. Malnutrition prevalence was 28% (52/185). IPF patients with low FFMI had higher mortality compared to patients with normal FFMI (p=0.015). In multivariable analyses, factors independently associated with mortality were active cancer, FFMI and BMI.
Introduction: Pulmonaryhypertension (PH) is a common complication of idiopathic pulmonary fibrosis (IPF) that is associated with poor prognosis. Screening for PH in IPF patients proves to be challenging.. Hypothesis: We hypothesized that combining several non-invasive studies can predict the presence of PH in IPF patients.. Methods: We included 235 IPF patients who underwent right heart catheterization (RHC) as part of the lung transplant evaluation. We measured ECG and echocardiographic variables as well as the pulmonary artery (PA) diameter and ascending aorta (AA) diameters on chest CT. We recorded results of arterial blood gases (ABG), pulmonary function (PFT) and 6-min walk tests (6MWT).. Results: Several variables were predictors of PH in IPF patients in univariate models including arterial oxygenation, 6MWT distance, worse right ventricular (RV) function, the QRS axis, FVC/DLCOc ratio, PA/AA diameter ratio and estimated RV systolic pressure. In multivariate analysis, RV function and PA/AA ...
There are no data regarding the late toxicity of trastuzumab (T) administration with radiotherapy (RT). In this experimental study, we aimed to asses if concurrent or sequential administration of T has any impact for the development of radiation-induced pulmonary fibrosis in rats. Fifty-four female Wistar-albino rats were divided into 6 groups. First group of rats (Group 1; concurrent T) had irradiation to whole thoracic region concurrently with T. Second group (Group 2: sequential T-RT) received thoracic irradiation, 1 week after T. Third group (Group 3: sequential RT-T) had thoracic irradiation first and they had T injection 1 week after RT. Fourth group (Group 4: T only) had only T application. Fifth group (Group 5: RT) had only RT. The last group (Group 6: sham) of rats were observed without any application. A single dose of 12 Gy was given to both lungs with an anterior field at 2 cm depth. T dose which was equivalent to 6 mg/kg adult dose was calculated for each rat, and injected by the ...

Brussels, Belgium, 22 February 2016 - Patient groups from nine European countries have come together to establish the European Idiopathic Pulmonary Fibrosis & Related Disorders Federation (EU-IPFF) in order to defend the interests of European patients with idiopathic pulmonary fibrosis (IPF) through one unified voice. IPF is a progressive, irreversible chronic disease of the lungs,1 with currently no known cure. EU-IPFF will push forward the IPF agenda at European level by improving patient access to treatment, increasing disease awareness, and advocating for research into new treatment options.. The newly formed federation represents an important landmark for the independent IPF patient groups and is the culmination of their continued fruitful collaboration building on initiatives like the IPF World Week Awareness Campaign and the IPF Patient Charter (www.ipfcharter.org). EU-IPFF will continue to collaborate with relevant medical organisations and bodies to ensure that the Charter ...

In this study, after doses of 1 g/kg/day of the traditional Chinese formula Ma-Xing-Shi-Gan-Tang (MXSGT), significant reversal of pneumatocysts was achieved in Spague-Dawley rats with bleomycin-induced lung fibrosis. We found that MXSGT can improve the damaged condition of general cellular membranes. Greatly increased levels of lung NO were found in the bleomycin-induced group, which were then significantly reduced by MXSGT. MXSGT drastically prevented depletion of superoxide dismutase (SOD) and reduced the myeloperoxidase (MPO) activities and malondialdehyde (MDA) levels in lung tissue of rats treated with bleomycin. On the basis of the results presented in this paper, MXSGT prevents bleomycin-induced lung fibrosis, and the mechanism may be due to the inhibitory effect on nitric oxide generation in the bleomycin-induced lung-fibrosis model of rats ...
Idiopathic pulmonary fibrosis is a progressive disease that causes unremitting extracellular matrix deposition with resulting distortion of pulmonary architecture and impaired gas exchange. β-Arrestins regulate G protein (heterotrimeric guanine nucleotide-binding protein)-coupled receptors through receptor desensitization while also acting as signaling scaffolds to facilitate numerous effector pathways. Here, we examine the role of β-arrestin1 and β-arrestin2 in the pathobiology of pulmonary fibrosis. In the bleomycin-induced mouse lung fibrosis model, loss of either β-arrestin1 or β-arrestin2 resulted in protection from mortality, inhibition of matrix deposition, and protected lung function. Fibrosis was prevented despite preserved recruitment of inflammatory cells and fibroblast chemotaxis. However, isolated lung fibroblasts from bleomycin-treated β-arrestin-null mice failed to invade extracellular matrix and displayed altered expression of genes involved in matrix production and ...
Idiopathic pulmonary fibrosis (IPF) is a chronic irreversible and fatal disease caused by a progressive decline in lung function.[1][2] The term pulmonary fibrosis means scarring of lung tissue and is the cause of worsening dyspnea (shortness of breath). Fibrosis is usually associated with a poor prognosis.[1][2][3] IPF belongs to a large group of more than 200 lung diseases known as interstitial lung diseases (ILDs), characterized by the involvement of lung interstitium. IPF usually occurs in adults of between 50 and 70 years of age, particularly those with a history of cigarette smoking, and affects more men than women. Treatment to slow down the progression of the disease may include nintedanib or pirfenidone.[4] ...
