Idiopathic pulmonary fibrosis (IPF) is a progressive age-related lung disease, the cause of which is not been fully understood. IPF is a devastating disease with mortality worse than many cancers, and treatment options are limited. IPF is thought to occur after recurrent injury to the alveolar epithelium followed by abnormal repair characterized by the formation of fibroblast and myofibroblast foci and excessive deposition of extracellular matrix. An updated classification of the idiopathic interstitial pneumonias has encouraged a large number of clinical trials. On the whole, these have disappointed. Improvements in molecular techniques have developed our understanding of IPF and with it identified new pathways and potential targets for therapeutic intervention. These insights are leading to interest in biomarkers of disease progression and prognosis and to novel anti-fibrotic agents and a more targeted approach to the treatment of IPF. 相似文献

特发性肺纤维化(idiopathic pulmonary fibrosis, IPF)是病因不明,组织病理学主要为普通间质性肺炎,局限于肺部的慢性纤维化型间质性肺炎。该病致死率高,对人群健康危害性高。近年来,随着人口老龄化、空气污染的加剧导致其发病率逐年上升,我们对于IPF的认识也在不断提高,研究发现IPF患者常合并其他疾病,包括肺气肿、肺癌、心血管疾病等。存在合并症的IPF患者临床症状更多,患者的生存质量差。其中合并肺动脉高压会降低IPF患者的生存率,本文就IPF合并肺动脉高压进行综述,以期为IPF合并肺动脉高压的诊疗方案与进一步研究提供新思路,以期提高 IPF患者的生活质量及改善预后。 相似文献

Idiopathic pulmonary fibrosis (IPF) represents a particularly aggressive disease, the aetiology of which still remains unknown. The natural history of the disease often leads to respiratory failure and death, with a mortality rate greater than some cancers. To date, no management approach has proven to be efficacious for the treatment of this disease. IPF has been characterised as an 'epithelial-fibroblastic disorder', characterised by abnormal wound healing with excessive fibrosis and minimal inflammation. These emerging data have focused attention on antifibrotic drugs. Interferon-gamma1b (IFN-gamma1b) has recently been proposed as a promising candidate for the treatment of IPF. The reason for this is that IFN-gamma1b has the ability to modulate the Th1/Th2 imbalance and to suppress fibroblast activation. The view that IPF is untreatable at present requires reconsideration, as improved survival has been suggested in three controlled trials of IFN-gamma1b in IPF therapy. 相似文献

Despite several advances in treatment, idiopathic pulmonary fibrosis (IPF) remains a progressive, symptomatic, and terminal disease in patients not suitable for lung transplantation. With disease progression, IPF often leads to a constellation of symptoms, including dyspnea, cough, anxiety, and depression. Palliative care is appropriate to support these patients. However, traditional curriculum in palliative care has often focused on supporting patients with malignant disease, and clinicians are not universally trained to manage patients with progressive nonmalignant diseases such as IPF. Current antifibrotic therapies aim to slow disease progression but are not able to reduce symptoms or improve daily function and health-related quality of life (HRQL). Palliative care in this patient group requires an understanding of the clinical characteristics of IPF, comorbidities, common medications used, and nonpharmacological strategies that can be undertaken to improve daily function and HRQL. This review focuses on IPF management strategies and their effects on symptoms, exercise tolerance, HRQL, and survival. Pharmacological interactions and considerations related to commonly used palliative care medications are also reviewed. This review highlights the needs of patients with IPF and caregivers, psychosocial function, patient-reported assessment tools, and topics related to advance care planning. 相似文献

Idiopathic pulmonary fibrosis (IPF) affects hundreds of thousands of people worldwide, reducing their quality of life and leading to death from respiratory failure within years of diagnosis. Treatment options remain limited, with only two FDA-approved drugs available in the United States, neither of which reverse the lung damage caused by the disease or prolong the life of individuals with IPF. The only cure for IPF is lung transplantation. In this review, we discuss recent major advances in our understanding of the role of the immune system in IPF that have revealed immune dysregulation as a critical driver of disease pathophysiology. We also highlight ways in which an improved understanding of the immune system’s role in IPF may enable the development of targeted immunomodulatory therapies that successfully halt or potentially even reverse lung fibrosis. 相似文献

Idiopathic pulmonary fibrosis (IPF) is a dreadful, chronic, and irreversibly progressive fibrosing disease leading to death
in all patients affected, and IPF acute exacerbations constitute the most devastating complication during its clinical course.
IPF exacerbations are subacute/acute, clinically significant deteriorations of unidentifiable cause that usually transform
the slow and more or less steady disease decline to the unexpected appearance of acute lung injury/acute respiratory distress
syndrome (ALI/ARDS) ending in death. The histological picture is that of diffuse alveolar damage (DAD), which is the tissue
counterpart of ARDS, upon usual interstitial pneumonia, which is the tissue equivalent of IPF. ALI/ARDS and acute interstitial
pneumonia share with IPF exacerbations the tissue damage pattern of DAD. 'Treatment' with high-dose corticosteroids with or
without an immunosuppressant proved ineffective and represents the coup de grace for these patients. Provision of excellent
supportive care and the search for and treatment of the 'underlying cause' remain the only options. IPF exacerbations require
rapid decisions about when and whether to initiate mechanical support. Admission to an intensive care unit (ICU) is a particular
clinical and ethical challenge because of the extremely poor outcome. Transplantation in the ICU setting often presents insurmountable
difficulties. 相似文献

特发性肺纤维化(IPF)是一种慢性进行性的间质性肺病,其发病机制目前尚无定论。成纤维细胞直接参与IPF过程的理论已被广泛接受,同时研究认为IPF的形成、发展与炎症、免疫息息相关,主要表现为免疫细胞与成纤维细胞间的相互作用。外泌体是细胞间进行生物信息通信的重要载体,不同细胞来源的外泌体携带着不同的信号因子,可作为免疫细胞与成纤维细胞的桥梁,在IPF的炎症反应和免疫调节中发挥作用,同时外泌体或将成为临床诊断和治疗IPF的重要方法。该文就不同细胞来源的外泌体在IPF中的研究进展进行综述,以了解外泌体作为细胞间信息交流的载体在调节IPF的形成与发展中的作用。 相似文献

BackgroundIdiopathic pulmonary fibrosis (IPF) is a chronic, progressive and fatal pulmonary fibrotic disease and useful biomarkers are required to diagnose and predict disease activity. CCN2 (connective tissue growth factor; CTGF) has been reported as one of the key profibrotic factors associated with transforming growth factor-β (TGF-β), and its assay has potential as a non-invasive measure in various fibrotic diseases. Recently, we developed a new subtraction method for determination of plasma CCN2 levels. We examined the utility of plasma CCN2 levels as a surrogate marker in IPF.MethodsPlasma CCN2 levels were calculated in 33 patients with IPF, 14 patients with non-IPF idiopathic interstitial pneumonias (IIPs) and 101 healthy volunteers by sandwich enzyme-linked immunosorbent assay (ELISA) using specific monoclonal antibodies for two distinct epitopes of human CCN2. We evaluated the utility of plasma CCN2 levels by comparison with clinical parameters.ResultsPlasma CCN2 levels were significantly higher in patients with IPF than in those with non-IPF IIPs and healthy volunteers. Importantly, plasma CCN2 levels showed significantly negative correlation with 6-month change of forced vital capacity (FVC) in patients with IPF.ConclusionsPlasma CCN2 is a potential biomarker for IPF. 相似文献
