REVIEW
Fengge Zhu, Xueyuan Bai, Xiangmei Chen
Fibrosis is defined as an excessive deposition of extracellular matrix (ECM), which leads to the destruction of organ structure and impairment of organ function. Fibrosis occurs not only in kidney but also in lung, liver, heart, and skin. Common pathways of fibrosis are thought to exist. Renal interstitial fibrosis is a complex process that involves multiple molecular signaling and multiple cellular components, in which B cells appear to be one of the emerging important players. B cells may affect fibrosis through cytokine production and through interaction with other cells including fibroblasts, macrophages and T cells...

Introduction: Antisynthetase syndrome (ASS) is characterized by the presence of anti-Jo-1 antibodies in conjunction with clinical findings of fever, polymyositis-dermatomyositis, and interstitial lung disease (ILD). Inflammatory myopathies carry a high risk of malignancy, but this association is less well outlined in ASS. We present the case of a patient with ASS who developed non-Hodgkin's lymphoma with acute hypoxemic respiratory failure. Case Presentation: A 44-year-old female with ASS presented with acute hypoxemic respiratory failure...

I am a young doctor who graduated from the Medical University of Silesia in 2014. After 13 months of postgraduate training, passing a state examination and successful completion of the admission process I made a decision to specialise in Respiratory Medicine. I started working in a large clinical hospital that provides junior doctors with excellent opportunities for training and career development. The respiratory unit is highly specialised and deals with sleep-related medical problems, interstitial lung diseases and respiratory failure, which may be treated using noninvasive mechanical ventilation...

Chilaiditi sign is the peculiar radiographic presentation of interposition of colon between diaphragm and liver. When associated with symptomatology, it is called as chilaiditi's syndrome. Though rare, respiratory symptoms may be present. In such cases, it becomes difficult to determine if the symptomatology is due to the syndrome only, or there is some underlying lung involvement, until this is specifically considered in the differential diagnosis. We present a male patient, where thorough investigations revealed Interstitial Lung Disease (ILD), along with Chilaiditi sign on chest radiograph...

PURPOSE OF REVIEW: To provide an overview of recently published articles covering interstitial lung disease associated with rheumatoid arthritis (RA-ILD). RECENT FINDINGS: Over the past year, many studies replicated previous findings in more diverse and occasionally larger populations internationally. Specifically, the association among cigarette smoking, high rheumatoid factor titer, elevated anticitrullinated protein antibody (ACPA) levels, and RA-ILD was strengthened...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic progressive interstitial lung disease with severe pulmonary fibrosis. The main cause of IPF-associated death is acute exacerbation of IPF (AE-IPF). This study aims to develop a rat model of AE-IPF by two intratracheal perfusions with bleomycin (BLM). METHODS: Ninety male Sprague Dawley (SD) rats were randomized into three groups: an AE-IPF model group (BLM + BLM group), an IPF model group (BLM group), and a normal control group...

BACKGROUND: Innate T helper type 2 (Th2) immune responses mediated by interleukin (IL)-33, thymic stromal lymphopoietin (TSLP), and IL-25 have been shown to play an important role in pulmonary fibrosis of animal models; however, their clinical implications remain poorly understood. METHODS: TSLP, IL-25, and IL-33 concentrations were measured in bronchoalveolar lavage fluids obtained from normal controls (NCs; n = 40) and from patients with idiopathic pulmonary fibrosis (IPF; n = 100), non-specific interstitial pneumonia (NSIP; n = 22), hypersensitivity pneumonitis (HP; n = 20), and sarcoidosis (n = 19)...

The lung alveoli slowly self-renew pneumocytes, but their facultative regeneration capacity is rapidly efficient after an injury, so fibrosis infrequently occurs. We recently observed Keratin 14 (KRT14) expression during diffuse alveolar damage (DAD), but not in controls. We wonder if KRT14 may be a marker of pneumocyte transition from quiescence to regeneration. Quantitative PCR and Western blot analyses highlighted the presence of KRT14 (mRNA and protein) only in human lung samples with DAD or interstitial lung disease (ILD)...

Interstitial pneumonia with autoimmune features (IPAF) is a term to describe individuals with both interstitial lung disease (ILD) and combinations of other clinical, serologic, and/or pulmonary morphologic features, which presumably originate from an underlying systemic autoimmune condition, but do not meet current rheumatologic criteria for a defined connective tissue disease (CTD). Predominantly, interstitial pneumonia arises in the course of an established CTD, but it is not so rare for the ILD to be the first, and possibly the one and only manifestation of a latent CTD...

OBJECTIVES: To investigate risk factors for radiation-induced pneumonitis (RP) after hypofractionated stereotactic body radiotherapy (SBRT) in patients with lung tumors. METHODS: From May 2004 to January 2016, 66 patients with 71 primary or metastatic lung tumors were treated with SBRT; these 71 cases were retrospectively analyzed for RP. To explore the risk factors for RP, the following factors were investigated: age, sex, performance status, operability, number of treatments, respiratory gating, pulmonary emphysema, tumor location, and subclinical interstitial lung disease (ILD)...

The complement system contributes to ventilator induced lung injury (VILI). We hypothesized that pretreatment with the C1 esterase inhibitor (C1INH) Berinert® constrains complement activation consecutively inducing improvements in arterial oxygenation and histological pulmonary damage. At baseline, male Sprague-Dawley rats underwent mechanical ventilation in a conventional mode (PIP 13 cm H2O, PEEP 3 cm H2O). In the Control group, the ventilator setting was maintained (Control, n = 15). The other animals randomly received intravenous pretreatment with either 100 units/kg of the C1-INH Berinert® (VILI-C1INH group, n = 15) or 1 ml saline solution (VILI-C group, n = 15)...

The most well-known disease caused by cotton dust is byssinosis though it is also associated with chronic obstructive airways disease, and very rarely, interstitial lung disease. Obliterative bronchiolitis has never been reported in this setting. We report a 63-year-old, nonsmoker male, who presented with complaints of cough and exertional dyspnoea for 10 years. He had worked in textile industry for 35 years and symptoms had persisted even after quitting. Examination revealed prolonged expiration with expiratory wheeze, and pulmonary function tests revealed severe airflow limitation with air trapping and impaired diffusion capacity...

BACKGROUND: The crocidolite variety of asbestos is banned. However, chrysotile, which is not prohibited, is still used in developing countries in making products such as clutch plate. Fourteen workers from a small-scale clutch plate-manufacturing factory were analyzed for asbestos-induced lung disease as one of their colleagues had expired due to asbestosis. AIMS: This study was conducted to evaluate the awareness of workers, the prevalence and type of asbestos-induced lung disease, and the sensitivity and specificity of diffusion test...

AIMS: Co-trimoxazole maintains a well-established role in the treatment of Pneumocystis jirovecii and Toxoplasma gondii, as well as urinary tract infections. Observational studies report hyperkalemia associated with co-trimoxazole which may stem from an amiloride-like potassium sparing effect. Our study reports on changes in serum potassium on patients without acute infections, and the influence of concomitant anti-kaliuretic drugs on this effect. METHODS: Post-hoc analysis of a randomised controlled trial in patients with interstitial lung disease who were assigned to placebo or 960 mg twice daily co-trimoxazole...

This study aims to explore the clinical characteristics and risk factors of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD). This is a retrospective study of 550 patients with RA. All patients underwent chest high-resolution computed tomography (HRCT) scanning. (1) Two hundred thirty-seven out of five hundred fifty (43.1%) patients with RA were diagnose with ILD. 13.5% ILD occurred before RA onset, 69.6% ILD occurred within 10 years of RA onset, and 16.9% ILD occurred more than 10 years after RA onset...

Pericytes are perivascular PDGFRβ+ stromal cells required for vasculogenesis and maintenance of microvascular homeostasis in many organs. Because of their unique juxtaposition to microvascular endothelium, lung PDGFRβ+ cells are well situated to detect pro-inflammatory molecules released following epithelial injury and promote acute inflammatory responses. Thus, we hypothesized that these cells represent an unrecognized immune surveillance or injury-sentinel interstitial cell. To evaluate this hypothesis, we isolated PDGFRβ+ cells from murine lung and demonstrated that they have characteristics consistent with a pericyte population (referred to as pericyte-like cells for simplicity hereafter)...

Purpose To investigate the prevalence of diffuse pulmonary ossification (DPO) in patients with fibrosing interstitial lung disease (ILD) and determine whether there are differences among the types of ILDs. Materials and Methods Institutional review board approval was given and patient consent was not required for this study. The study population comprised 892 consecutive patients with fibrosing ILD, including 456 patients with idiopathic pulmonary fibrosis (IPF) (men, 366; women, 90; median age, 72 years [range, 38-93 years]), 244 with nonspecific interstitial pneumonia (men, 79; women, 165; median age, 60...
