Diffuse lung diseases

Racquel Domingo-Gonzalez, Oliver Prince, Andrea Cooper, Shabaana A Khader
Chemokines and cytokines are critical for initiating and coordinating the organized and sequential recruitment and activation of cells into Mycobacterium tuberculosis-infected lungs. Correct mononuclear cellular recruitment and localization are essential to ensure control of bacterial growth without the development of diffuse and damaging granulocytic inflammation. An important block to our understanding of TB pathogenesis lies in dissecting the critical aspects of the cytokine/chemokine interplay in light of the conditional role these molecules play throughout infection and disease development...

BACKGROUND AND OBJECTIVE: Idiopathic pulmonary fibrosis (IPF) is a progressive disease with poor prognosis and variable clinical course. Although matrix metalloproteinase-7 (MMP-7) is emerging as an important IPF biomarker, reproducibility across studies is unclear. We aimed to determine whether a previously reported prognostic threshold for MMP-7 was predictive of mortality in an independent cohort of IPF patients. METHODS: MMP-7 concentrations obtained from heparinized plasma samples were determined by ELISA in 97 patients with IPF and 41 healthy controls...

BACKGROUND: Palliative care has been recommended as a means to assist patients with idiopathic pulmonary fibrosis (IPF) in managing symptom burden and advanced care planning. Timing of referral is important because although most patients display a gradually progressive course, a minority experience acute deterioration, an outcome associated with high mortality. AIM: To describe characteristics of IPF patients referred to a specialty lung disease center over a 10-year period who experienced acute deterioration and subsequent intensive care unit (ICU) admission, including frequency and timing of referral to palliative care...

Foreign body granulomatosis is a rare complication of intravenous injection of pulverized oral prescription tablets. We present the case of an active duty male who was ultimately diagnosed with foreign body granulomatosis caused by the crushing and intravenous injection of acetaminophen with oxycodone (Percocet). The 24-year-old patient initially presented with multiple syncopal episodes, hemoptysis and hypoxia. The patient presentation and imaging findings involved in foreign body granulomatosis can mimic many pulmonary disorders and can be widely variable...

Plasma-cell post-transplantation lymphoproliferative disorder (PC-PTLD) is a rare monomorphic PTLD entity divided into plasma cell myeloma (PCM) and plasmacytoma-like lesion (PLL) PTLD. To date, there are no exhaustive published cytogenetic data on PC-PTLD. We report array-based comparative genomic hybridization (aCGH) of 10 cases of PCM and PLL-PTLD. Patients had received kidney (n=6), heart (n=2), lung (n=1) or bone marrow (n=1) transplantation. There were six men and median age at time of PTLD was 56.5 years (3-74)...

A 44-year-old male developed interstitial lung disease (ILD) during treatment with rituximab (375 mg/m(2) weekly intravenous × 4 weeks) for the management of immune thrombocytopenia (ITP). After 1 month of treatment he developed dyspnea, fever (38.9 °C), an increase of C-reactive protein (CRP) and white blood cells with hypoxemia, and decreased platelets. Chest X-ray and high-resolution computed tomography revealed diffuse bilateral lung infiltrates. He was diagnosed with severe ILD; rituximab was discontinued, and treatment with fluticasone combined with salmeterol, methylprednisolone, and omeprazole was started, with an improvement of symptoms over 15 days with normalization in CRP at 30 days...

Objective The influence of smoking on the pathogenesis and clinical course of interstitial pneumonia has recently attracted attention. To clarify the influence of smoking on the clinical patient characteristics and therapeutic effects in patients with interstitial pneumonia presenting with a non-specific interstitial pneumonia (NSIP) pattern, we compared the clinical patient characteristics and therapeutic effects in smokers and nonsmokers in this study. Methods We divided 31 NSIP (16 idiopathic nonspecific interstitial pneumonia and 15 collagen vascular disease-associated nonspecific interstitial pneumonia) patients into smoker and non-smoker groups for each case...

BACKGROUND: Lung volume reduction surgery (LVRS) performed to treat patients with severe diffuse emphysema was reintroduced in the nineties. Lung volume reduction surgery aims to resect damaged emphysematous lung tissue, thereby increasing elastic properties of the lung. This treatment is hypothesised to improve long-term daily functioning and quality of life, although it may be costly and may be associated with risks of morbidity and mortality. Ten years have passed since the last version of this review was prepared, prompting us to perform an update...

RATIONALE: Patients without a known history of lung disease presenting with a spontaneous pneumothorax are generally diagnosed as primary spontaneous pneumothorax. However, occult diffuse cystic lung diseases such as Birt-Hogg-Dubé syndrome (BHD), lymphangioleiomyomatosis (LAM), and pulmonary Langerhans cell histiocytosis (PLCH) can also first present with a spontaneous pneumothorax, and their early identification by high-resolution computed tomographic (HRCT) imaging of chest has implications for subsequent management...

PURPOSE: To present a method for simultaneous acquisition of alveolar oxygen tension (PA O2 ), specific ventilation (SV), and apparent diffusion coefficient (ADC) of hyperpolarized (HP) gas in the human lung, allowing reinterpretation of the PA O2 and SV maps to produce a map of oxygen uptake (R). METHOD: An imaging scheme was designed with a series of identical normoxic HP gas wash-in breaths to measure ADC, SV, PA O2 , and R in less than 2 min. Signal dynamics were fit to an iterative recursive model that regionally solved for these parameters...

Culturing cells at the air-liquid interface (ALI) is essential for creating functional in vitro models of lung tissues. We present the use of direct-patterned laser-treated hydrophobic paper as an effective semi-permeable membrane, ideal for ALI cell culture. The surface properties of the paper are modified through a selective CO2 laser-assisted treatment to create a unique porous substrate with hydrophilic regions that regulate fluid diffusion and cell attachment. To select the appropriate model, four promising hydrophobic films were compared with each other in terms of gas permeability and long-term strength in an aqueous environment (wet-strength)...

BACKGROUND: Visceral adipose tissue (VAT) was shown to be increased in patients with chronic obstructive pulmonary disease (COPD) compared to control subjects with comparable body mass index (BMI). Our aim was to determine the relation of VAT by dual-energy x-ray absorptiometry (DEXA) in patients with COPD by disease severity, BMI, other indices of body composition and static lung volumes. METHODS: 294 COPD patients admitted for rehabilitation were studied. Lung function, static lung volumes and body composition (i...

Pulmonary nodular lymphoid hyperplasia (PNLH) may show heavy lymphoplasmacytic infiltrates with increased Immunoglobulin G4 (IgG4)-positive plasma cells as in IgG4-related disease (IgG4-RD). However, it is unclear whether PNLH could be a manifestation of IgG4-RD. A recent study reported the presence of Epstein-Barr virus (EBV) in IgG4-related lymphadenopathy. We postulated that a subset of PNLH might represent IgG4-related lung disease (IgG4-RLD) with EBV-positive lymphocytes as has been reported in IgG4-related lymphadenopathy...

Idiopathic interstitial pneumonias are a heterogeneous group of diffuse lung diseases characterized by distinct clinicopathologic entities with the usual interstitial pneumonia (UIP) being the most common. The pattern of UIP can be seen in idiopathic pulmonary fibrosis (IPF) as well as in secondary causes, most commonly in connective tissue diseases. IPF is usually progressive and associated with a very poor prognosis, and newer therapies pose a risk of serious complications; therefore, diagnostic certainty is crucial...

The direct toxicity of cigarette smoke and the body's subsequent response to this lung injury leads to a wide array of pathologic manifestations and disease states that lead to both reversible and irreversible injury to the large airways, small airways, alveolar walls, and alveolar spaces. These include emphysema, bronchitis, bronchiolitis, acute eosinophilic pneumonia, pulmonary Langerhans cell histiocytosis, respiratory bronchiolitis, desquamative interstitial pneumonia, and pulmonary fibrosis. Although these various forms of injury have different pathologic and imaging manifestations, they are all part of the spectrum of smoking-related diffuse parenchymal lung disease...

BACKGROUND: Organizing pneumonia (OP) can be idiopathic or secondary to some clinical situations. If an etiological cause is not present, this phenomenon is called cryptogenic OP. Secondary OP is associated with various diseases that are known to induce the OP. OBJECTIVES: The aim of this study was to evaluate the clinical features of the cases with OP and compare the patients diagnosed by bronchoscopic transbronchial biopsy with patients diagnosed by surgical lung biopsy...

Löffler syndrome, a fulminant eosinophilic pneumonitis associated with the larval migratory phase of human parasites, is rarely reported in the United States. A previously healthy 8-year-old male was hospitalized with tachypnea, cough, hypoxemia, and fever of one week's duration. History revealed exposure to pigs on his family's farm in southernmost Louisiana, where the patient was responsible for cleaning the farm's pigpens. His fingernails were soiled and extremely short, with the edge of the nail bed exposed secondary to onychophagia...
