BACKGROUND: Approximately 30% of patients with Crohn disease (CD) are unresponsive to biologics. No previous study has focused on a plant-based diet in an induction phase of CD treatment. OBJECTIVE: To investigate the remission rate of infliximab combined with a plant-based diet as first-line (IPF) therapy for CD. METHODS: This was a prospective single-group trial conducted at tertiary hospitals. Subjects included consecutive adults with a new diagnosis (n = 26), children with a new diagnosis (n = 11), and relapsing adults (n = 9) with CD who were naïve to treatment with biologics...

OBJECTIVE: To investigate the impacts of particulate matter 2.5 (PM2.5) from straw burning on the acute exacerbation of lung fibrosis in mice and the preventive effects of N-acetylcysteine (NAC). METHODS: The composition, particle size, and 30-min concentration change in an exposure system of the PM2.5 from straw-burning were determined. Forty C57BL male mice were equally randomized to two groups: bleomycin (BLM)-induced lung fibrosis with an exposure to air (BLM+air) and BLM+PM2...

We consecutively examined the utility of measurements of percentage of immature platelet fraction (IPF%) and absolute IPF number (A-IPF) in predicting thrombopoietic recovery in 15 adult patients who underwent allogeneic hematopoietic stem cell transplantation (allo-SCT). Four patients were excluded from the evaluation due to insufficient data. Platelet count and IPF were measured by Sysmex XN-1000 (XN), a newer generation analyzer. First, we confirmed that platelet count measured by XN was more accurate than by XE-2100 (XE)...

Little is known about when symptoms of idiopathic pulmonary fibrosis first develop. We identified incident cases of idiopathic pulmonary fibrosis-clinical syndrome (IPF-CS) from a UK primary care database and assessed the frequency of consultations for common symptoms in the 5 years prior to diagnosis. 1671 cases were identified with 5 years of data prior to diagnosis. Breathlessness was the most common symptom, followed by cough. Cases were significantly more likely than controls to experience these symptoms (p<0...

Glutaminolysis is the metabolic process of glutamine, of which aberration has been implicated in several pathogeneses. While we and others recently found a diversity of metabolic dysregulations in organ fibrosis, it is unknown if glutaminolysis regulates the pro-fibrotic activities of myofibroblasts, the primary effector in this pathology. In this study, we found that lung myofibroblasts demonstrated significantly augmented glutaminolysis that was mediated by elevated Glutaminase 1 (Gls1). Inhibition of glutaminolysis by specific Gls1 inhibitors CB-839 and BPTES as well as Gls1 siRNA blunted the expression of collagens, but not that of Fibronectin, Elastin or myofibroblastic marker smooth muscle actin α (SMA-α)...

Organ fibrosis, including idiopathic pulmonary fibrosis (IPF), is associated with significant morbidity and mortality. Since currently available therapies have limited effect, there is need to better understand the mechanisms by which organ fibrosis occurs. We have recently reported that TGF-β, a key cytokine which promotes fibrogenesis, induces the expression of the enzymes of the de novo serine and glycine synthesis pathway in human lung fibroblasts and that phosphoglycerate dehydrogenase (PHGDH, the first and rate limiting enzyme of the pathway) is required to promote collagen protein synthesis downstream of TGF-β...

600 patients aged ≥18 years will be randomised in a 1:1 ratio to nintedanib or placebo. Patients with diagnosis of IPF will be excluded. The study population will be enriched with two-thirds having a usual interstitial pneumonia-like pattern on HRCT. The primary endpoint is the annual rate of decline in forced vital capacity over 52 weeks. The main secondary endpoints are the absolute change from baseline in King's Brief Interstitial Lung Disease Questionnaire total score, time to first acute interstitial lung disease exacerbation or death and time to all-cause mortality over 52 weeks...

BACKGROUND: Recent evidences show that Pulmonary Rehabilitation (PR) is effective in patients with Interstitial Lung Disease (ILD). It is still unclear whether disease severity and/or etiology might impact on the reported benefits. We designed this prospective study 1) to confirm the efficacy of rehabilitation in a population of patients with ILDs and 2) to investigate whether baseline exercise capacity, disease severity or ILD etiology might affect outcomes. METHODS: Forty-one patients (IPF 63%, age 66...

Idiopathic pulmonary fibrosis (IPF), the most common form of idiopathic interstitial pneumonia (IIP), is characterized by irreversible scarring of the lung parenchyma and progressive decline in lung function leading to eventual respiratory failure. The prognosis of IPF is poor with a median survival of 3-5 years after diagnosis and no curative medical therapies. Although the pathogenesis of IPF is not well understood, there is a growing body of evidence that genetic factors contribute to disease risk. Recent studies have identified common and rare genetic variants associated with both sporadic and familial forms of pulmonary fibrosis, with at least one-third of the risk for developing fibrotic IIP explained by common genetic variants...

Idiopathic pulmonary fibrosis (IPF) is characterized by a disturbed pulmonary redox balance associated with inflammation. To restore this balance, antioxidants are often suggested as therapy for IPF but previous clinical trials with these compounds and their precursors have not been successful in the clinic. The exogenous antioxidant quercetin, which has a versatile antioxidant profile and is effective in restoring a disturbed redox balance, might be a better candidate. The aim of this study was to evaluate the protective effect of quercetin on oxidative and inflammatory markers in IPF...

Cellular senescence, the irreversible loss of replicative capacity in somatic cells, plays a causal role in the development of age-related pathology and in a number of age-related chronic inflammatory diseases. The ageing lung is marked by an increasing number of senescent cells, and evidence is mounting that senescence may directly contribute to a number of age-related respiratory diseases, including chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). Telomere dysfunction and alterations in mitochondrial homeostasis frequently occur in cellular senescence and are important to the development of the often detrimental senescence-associated secretory phenotype (SASP)...

Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease with limited therapeutic options and unknown etiology. IPF is characterized by epithelial cell injury, impaired cellular crosstalk between epithelial cells and fibroblasts, and the formation of fibroblast foci with increased extracellular matrix deposition (ECM). We investigated the role of runt-related transcription factor 2 (RUNX2), a master regulator of bone development that has been linked to profibrotic signaling. RUNX2 expression was up-regulated in lung homogenates from patients with IPF and in experimental bleomycin-induced lung fibrosis...

Fibrosis, which can be defined as an abnormal or excessive accumulation of extracellular matrix (ECM), particularly fibrillar collagens, is a key driver of progressive organ dysfunction in many inflammatory and metabolic diseases, including idiopathic pulmonary fibrosis (IPF), cirrhosis, nephropathy, and oral submucous fibrosis (OSF). It has been estimated to contribute to ∼45% of deaths in the developed world. Therefore, agents that target specific fibrotic pathways, with the consequence of slowing, arresting, or even reversing the progression of tissue fibrogenesis, are urgently needed...

Idiopathic pulmonary fibrosis (IPF) is a fatal age-associated disease that is characterized by progressive and irreversible scarring of the lung. The pathogenesis of IPF is not completely understood and current therapies are limited to those that reduce the rate of functional decline in patients with mild-to-moderate disease. In this context, new therapeutic approaches that substantially improve the survival time and quality of life of these patients are urgently needed. Our incomplete understanding of the pathogenic mechanisms of IPF and the lack of appropriate experimental models that reproduce the key characteristics of the human disease are major challenges...

The past few years have signaled a major breakthrough on the management of idiopathic pulmonary fibrosis (IPF). Finally, we have drugs in our arsenal able to slow down the inexorable disease natural course. On the other hand, the latter evidence has increased the responsibility for a timely and accurate diagnosis. Establishment of IPF diagnosis directly affects the choice of appropriate treatment. The current diagnostic guidelines represent a major step forward providing an evidence-based road map; yet, clinicians are encountering major diagnostic dilemmas that inevitably affect therapeutic decisions...

Previous studies in our lab have demonstrated that Adenosine A2a receptor (A2aR) gene-knockout mice were vulnerable to pulmonary fibrosis induced by bleomycin (BLM). Inhibition of the SDF-1/CXCR4 axis has been reported to protect the lungs from fibrogenesis in BLM-exposed mice. Little is yet known about the relationships between A2aR and the SDF-1/CXCR4 axis in idiopathic pulmonary fibrosis (IPF). This study probes the role of A2aR in the fibrotic process and explores the relationship between A2aR and the SDF-1/CXCR4 axis in BLM-induced pulmonary fibrosis in mice...
